                                  after such notice of exercise is received);
                                  and with respect to Options for which notice

2.2      Options shall be granted only to such Eligible Employees as the
         Directors shall from time to time determine. No Eligible Employee shall
         be entitled as of right to participate. The extent of any participation
         shall be determined by the Directors in their absolute discretion.

         2.2.1    The Directors shall give notice in writing to any
                  Eligible Employee who they have determined shall be invited to
                  apply for the grant of an Option and such notice shall specify

                  (i)     the maximum number of Shares in respect of which the
                          Eligible Employee may apply for an Option;

                  (ii)    the Exercise price per Share; and

                  (iii)   the amount payable pursuant to rule 2.3 for the grant
                          of an Option.

         2.2.2   The Directors shall be entitled to specify in any invitation
                 given under rule 2.2.1 that:

                  (i)     the Option proposed to be granted shall contain
                          such objective conditions as the Directors may in
                          their discretion think fit being conditions which must
                          be fulfilled prior to exercise of the Option and which
                          are specified in or by the invitation;

                  (ii)    prior to specified dates the Option may not be
                          exercised in full but may only, prior to such dates,
                          be exercised as to specified proportions of the Shares
                          comprised therein.

         2.2.3    Each such Eligible Employee shall be given a notice
                  period from the date of the invitation during which he may
                  apply for an Option. Any such application shall state the
                  number of Shares in respect of which he wishes to be
                  considered for an Option, which number shall not exceed the
                  maximum of Shares specified in the invitation and shall be
                  accompanied by the sum payable pursuant to rule 2.3.

         2.2.4    The receipt of an invitation by an Eligible Employee and
                  any application by an Eligible Employee pursuant thereto shall
                  confer no rights on the Eligible Employee.

2.3      The application by an Eligible Employee for an Option shall be
         accompanied by payment of (pound)1, which payment shall (unless the
         application is rejected) not be refundable and shall not be deemed to
         be a payment on account of the Exercise price. In the event of the
         Directors rejecting an Eligible Employee's application, the payment
         which accompanied such application will be returned to the employee.

2.4      If such Eligible Employee shall make an application for an
         Option, the Directors will consider such application and will, if they
         in their absolute discretion so decide, grant the Option. The Date of
         Grant shall be the date on which the Directors so decide to grant the
         Option. The terms of the option shall include:

         (i)      the number of Shares in respect of which the Eligible
                  Employee has been granted an Option; and

Unapproved Share Option Sheme Rules                                           5

<PAGE>   6

         (ii)     the Exercise price per Share; and

         (iii)    any objective conditions of exercise which must be
                  fulfilled prior to exercise of the Option as may have been
                  specified in or by the relative invitation; and

         (iv)     a statement as to whether, prior to specified dates, the
                  Option may not be exercised in full but may only prior to
                  such dates be exercised as to specified proportions of the
                  Shares comprised therein.

2.5      It shall be a condition of participation in the Scheme that in
         the event of the dismissal of an Option holder from Employment in
         circumstances which could give rise to a claim for wrongful or unfair
         dismissal he shall not become entitled to any damages or any additional
         damages by reason of any alteration consequent thereupon of the Option
         holder's rights or expectations under the Scheme.

2.6      An Option shall be personal to the Option holder and shall not
         be assignable and any purported assignment, charge, disposal or
         dealing with the rights and interests of the Option holder under the
         Scheme shall be void and the Option shall cease to be exercisable,
         save that the devolution of an Option on the death of an Option holder
         whilst in Employment (or within three months of the Option holder
         ceasing to be in Employment) shall entitle the Option holder's
         personal representatives to exercise the Option subject to any
         applicable provisions of these rules.

2.7      Each Option shall be evidenced by an Option certificate in such
         form (not inconsistent with the provisions of the Scheme) as the
         Directors may from time to time determine. An option certificate shall
         be issued by the Company to each Option holder as soon as practicable
         after an Option has been granted. If any such certificate shall be worn
         out, defaced, destroyed or lost, it may be renewed on such evidence
         being provided as the Directors shall require.

3.       LIMITATION OF THE SCHEME

5.       EXERCISE OF OPTIONS - SPECIAL CASES

         Employee by reason of:

         5.1.1    injury or disability or redundancy (within the meaning of the
                  Employment Rights Act 1996);

         5.1.2    retirement either on reaching the age of 65 or at any

                  person who is not a company within the Group;

         5.1.5    any other circumstances approved by the Directors
                  (provided that if such approval is not given within one month
                  of cessation the Option shall lapse),

         any such Options may be exercised within 3 months of such cessation but
         shall lapse to the extent that it has not been exercised at the end of

         employment without notice, his employment shall be deemed to cease on
         the date on which the termination takes effect or, if earlier, the date
         of giving such notice. If the Option holder's employment is terminated
         by the Option holder or by his employer with notice his employment
         shall be deemed to cease on the date when such notice expires.

6.       EXERCISE OF OPTIONS - GENERAL

         to dates specified by the Directors the Option may not be exercised in

         proportions of the Shares comprised therein.

6.3      In no circumstances may an Option be exercised on  or  after the
         seventh anniversary of its Date of Grant.

6.4      Any reference (however expressed) to the exercise of an Option
         or an entitlement to exercise an Option shall be construed as exercise
         or entitlement to exercise (as the case may be) subject to the terms of
         the Option (including without limitation any requirement to satisfy an
         objective condition prior to exercise and any limit on entitlement at
         the date in question imposed pursuant to rule 6.1 save to the extent
         such requirement or limit has been waived by means of a resolution of
         the Directors pursuant to rule 9.1, 9.2, 9.4 or 9.5).

7.       MANNER OF EXERCISE OF OPTIONS

7.1      An Option shall be exercised by the Option holder (or the Option
         holder's personal representatives) giving notice in writing (in such
         form as the Directors may from time to time determine) to the Company
         stating that the Option is thereby exercised and the number of Shares
         in respect of which it is exercised. Such notice shall be accompanied
         by the relevant Option certificate and the Exercise price of the Shares
         in respect of which the Option is exercised. The Company shall, within
         30 days after receipt by the Directors of such notice, Option
         certificate and payment, unless prohibited by any enactment or
         regulation for the time being in force, either (i) allot and issue,
         fully paid, the Shares or (ii) procure the issue and allotment, or
         transfer of the Shares in respect of which the Option has been
         exercised into the name of the Option holder provided that, with
         respect to all Options for which notices of exercise are received by
         the Company on or after the Drag Along Date, no such allotment or
         transfer shall take place until the Qualifying Offer has either become
         unconditional, lapsed, or failed to become unconditional prior to 01
         July 2001.

7.2      Shares allocated on the exercise of an Option shall rank pari
         passu in all respects with the other issued Shares of the same class
         except that they will not rank for any dividend or other distribution
         of the Company made by reference to a record date prior to the date of
         exercise.

7.3      When an Option is exercised only in part the balance shall
         remain exercisable on the same terms as originally applied to the
         original Option and a new Option certificate shall be issued in
         accordance with rule 2.7 in respect of the balance as soon as
         practicable after the partial exercise.

8.       REORGANISATION OF SHARE CAPITAL

8.1      In the event of any reorganisation of ordinary share capital (as
         defined in rule 8.2) the Directors may make such adjustment as they
         consider appropriate with regard to:-

         8.1.1    the maximum number or amount of Shares subject to any Option;
                  and/or

         8.1.2    the Exercise price of any Shares subject to any Option;

                                            PROVIDED THAT

<PAGE>   9

         8.1.3    any such adjustment has been confirmed in writing by the
                  Auditors to be in their opinion fair and reasonable and has
                  been agreed to in writing by Parent; and

         8.1.4    the aggregate Exercise price payable by an Option holder on
                  the exercise of all Option holder Options is not increased;
                  and

         8.1.5    the amount payable to subscribe for any Share subject to any
                  Option shall not be reduced below its nominal value;  and

         8.1.6    the Directors shall give notice in writing to each Option
                  holder affected thereby of any adjustment made pursuant to
                  this rule 8 and may at their discretion deliver to him a
                  revised Option certificate in respect of his Option or an
                  addendum to his Option certificate; and

8.2      For the purpose of rule 8.1, a reorganisation of ordinary share
         capital means any capitalisation issue or rights issue or any
         consolidation, subdivision or reduction of capital.

9.       CHANGE OF CONTROL ETC

         (or any of them) any company obtains control of the Company, the
         Directors shall as soon as reasonably practicable notify every Option
         holder. The entitlement of Option holders to exercise their Options
         shall not be altered (save as may be provided elsewhere under these
         Rules) unless the Directors shall resolve within the period commencing
         six months prior to the date on which any company obtains control of
         the Company and ending three months thereafter that:

         9.1.1    all Options shall lapse on a date to be specified by the

         practicable notify every Option holder of such resolution PROVIDED
         ALWAYS that no Option shall lapse and cease to be exercisable by virtue
         of this rule 9.1 until the later of (a) the date on which any company
         obtains control of the Company and (b) one month after the date on
         which the notification is despatched to Option holders in accordance
         with this rule 9.1.

9.2      If any person:

                  (a)       either alone or together with any person
                            acting in concert with him has obtained control of
                            the Company as a result of a general offer to
                            shareholders in the Company (or any of them) or
                            otherwise; or

                  (b)       having such control makes a general offer to
                            acquire the whole of the issued share capital of the
                            company (other than that which is already owned by
                            him and whether or not excluding that which is
                            already owned by any person acting in concert with
                            him)

I would draw the following points to your attention:

ENTITLEMENT TO EXERCISE THE OPTION

If an option is granted to you, the option will not, or may not, be exercisable
in full immediately. The basis on which your entitlement to exercise your option
will vest is set out in the Application Form.

Your option will not be exercisable unless you have first, save as prohibited by
law, provided the Company with an indemnity in respect of any PAYE, and/or
employer's National Insurance Contributions and/or employee's National Insurance
Contributions which may arise on exercise. The terms of the indemnity are set
out in the Application Form and the implications of the indemnity are explained
in the Employee Guidelines.

Exercise of the option may only be effected in accordance with the Rules of the
Scheme.

EXERCISE PRICE

The price per share payable on exercise of an option is equal to the market
value of one Ordinary Share as determined by the Directors, in accordance with
the Rules of the Scheme.

TAX IMPLICATIONS

A summary of the tax implications under current law of applying for, being
granted and exercising an option is set out in the Employee Guidelines.

PRE-EMPTION RIGHTS AND "BUY-BACK" ARRANGEMENTS

Under the Articles of Association of the Company any Ordinary Shares acquired
following the exercise of your option will be subject to the following
restrictions:

(a)    you will not be permitted to sell your shares to any person until you
       have first offered them for sale to the existing shareholders and the
       Company (or if the Directors so direct) an employee benefit trust;

(b)    if you cease to be an employee or officer of the Company, you may be
       obliged to sell your Shares to the existing shareholders or to the
       Company or (if the Directors so direct) to an employee benefit trust;

in each case at a price and in a manner determined in accordance with the
Articles of Association.

LAPSE OF YOUR OPTION

Your option rights will lapse under the Rules of the Scheme in certain
circumstances and, in particular, if you leave the employment of the Company
your option will normally lapse on the date of your ceasing to be an employee.

Your option is personal to you and will lapse if you sell, transfer, charge or
otherwise deal with the option.

Your option will lapse on the seventh anniversary of its date of grant to the
extent that the option has not been exercised beforehand.

2.       GRANT OF OPTIONS

2.1      The Directors may in their absolute discretion, select from amongst the
         Eligible Employees those who, on a particular occasion, are to be
         invited to apply for Options.

2.2      Options shall be granted only to such Eligible Employees as the
         Directors shall from time to time determine. No Eligible Employee shall
         be entitled as of right to participate. The extent of any participation
         shall be determined by the Directors in their absolute discretion.

         2.2.1    The Directors shall give notice in writing to any Eligible
                  Employee who they have determined shall be invited to apply
                  for the grant of an Option and such notice shall specify

                  (i)    the maximum number of Shares in respect of which the
                         Eligible Employee may apply for an Option;

                  (ii)   the Exercise price per Share; and

                         of an Option.

         2.2.2    The Directors shall be entitled to specify in any invitation
                  given under rule 2.2.1 that:

                  (i)    the Option proposed to be granted shall contain such
                         objective conditions as the Directors may in their
                         discretion think fit being conditions which must be
                         fulfilled prior to exercise of the Option and which
                         are specified in or by the invitation;

                  (ii)   prior to specified dates the Option may not be
                         exercised in full but may only, prior to such dates,
                         be exercised as to specified proportions of the Shares
                         comprised therein.

         2.2.3    Each such Eligible Employee shall be given a notice period
                  from the date of the invitation during which he may apply for
                  an Option. Any such application shall state the number of
                  Shares in respect of which he wishes to be considered for an
                  Option, which number shall not exceed the maximum of Shares
                  specified in the invitation and shall be accompanied by the
                  sum payable pursuant to rule 2.3.

         2.2.4    The receipt of an invitation by an Eligible Employee and any
                  application by an Eligible Employee pursuant thereto shall
                  confer no rights on the Eligible Employee.

2.3      The application by an Eligible Employee for an Option shall be
         accompanied by payment of pound 1, which payment shall (unless the
         application is rejected) not be refundable and shall not be deemed to
         be a payment on account of the Exercise price. In the event of the
         Directors rejecting an Eligible Employee's application, the payment
         which accompanied such application will be returned to the employee.

                                       8

2.4      If such Eligible Employee shall make an application for an Option, the
         Directors will consider such application and will, if they in their
         absolute discretion so decide, grant the Option. The Date of Grant
         shall be the date on which the Directors so decide to grant the Option.
         The terms of the option shall include:

         (i)      the number of Shares in respect of which the Eligible Employee
                  has been granted an Option; and

         (ii)     the Exercise price per Share; and

         (iii)    any objective conditions of exercise which must be fulfilled
                  prior to exercise of the Option as may have been specified in
                  or by the relative invitation; and

         (iv)     a statement as to whether, prior to specified dates, the
                  Option may not be exercised in full but may only prior to such
                  dates be exercised as to specified proportions of the Shares
                  comprised therein.

2.5      It shall be a condition of participation in the Scheme that in the
         event of the dismissal of an Option holder from Employment in
         circumstances which could give rise to a claim for wrongful or unfair
         dismissal he shall not become entitled to any damages or any additional
         damages by reason of any alteration consequent thereupon of the Option
         holder's rights or expectations under the Scheme.

2.6      An Option shall be personal to the Option holder and shall not be
         assignable and any purported assignment, charge, disposal or dealing
         with the rights and interests of the Option holder under the Scheme
         shall be void and the Option shall cease to be exercisable, save that
         the devolution of an Option on the death of an Option holder whilst in
         Employment (or within three months of the Option holder ceasing to be
         in Employment) shall entitle the Option holder's personal
         representatives to exercise the Option subject to any applicable
         provisions of these rules.

2.7      Each Option shall be evidenced by an Option certificate in such form
         (not inconsistent with the provisions of the Scheme) as the Directors
         may from time to time determine. An option certificate shall be issued
         by the Company to each Option holder as soon as practicable after an
         Option has been granted. If any such certificate shall be worn out,
         defaced, destroyed or lost, it may be renewed on such evidence being
         provided as the Directors shall require.

         5.1.5    any other circumstances approved by the Directors (provided
                  that if such approval is not given within one month of
                  cessation the Option shall lapse),

         the Option (including without limitation any requirement to satisfy an
         objective condition prior to exercise and any limit on entitlement at

         form as the Directors may from time to time determine) to the Company
         stating that the Option is thereby exercised and the number of Shares
         in respect of which it is exercised. Such notice shall be accompanied
         by the relevant Option certificate and the Exercise price of the Shares
         in respect of which the Option is exercised. The Company shall, within
         30 days after receipt by the Directors of such notice, Option
         certificate and payment, unless prohibited by any enactment or
         regulation for the time being in force, either (i) allot and issue,
         fully paid, the Shares or (ii) procure the issue and allotment, or
         transfer of the Shares in respect of which the Option has been
         exercised into the name of the Option holder provided that, with

         unconditional, lapsed, or failed to become unconditional prior to 01
         July 2001.

7.2      Shares allocated on the exercise of an Option shall rank pari passu in
         all respects with the other issued Shares of the same class except that
         they will not rank for any dividend or other distribution of the
         Company made by reference to a record date prior to the date of
         exercise.

7.3      When an Option is exercised only in part the balance shall remain
         exercisable on the same terms as originally applied to the original

         Option certificate shall be issued in accordance with rule 2.7 in
         respect of the balance as soon as practicable after the partial
         exercise.

8.       REORGANISATION OF SHARE CAPITAL

8.1      In the event of any reorganisation of ordinary share capital (as
         defined in rule 8.2) the Directors may make such adjustment as they
         consider appropriate with regard to:-

         8.1.1    the maximum number or amount of Shares subject to any Option;
                  and/or

         8.1.2    the Exercise price of any Shares subject to any Option;

            PROVIDED THAT

         8.1.3    any such adjustment has been confirmed in writing by the
                  Auditors to be in their opinion fair and reasonable and has
                  been agreed to in writing by Parent; and

         8.1.4    the aggregate Exercise price payable by an Option holder on
                  the exercise of all Option holder Options is not increased;
                  and

         8.1.5    the amount payable to subscribe for any Share subject to any
                  Option shall not be reduced below its nominal value; and

         8.1.6    the Directors shall give notice in writing to each Option
                  holder affected thereby of any adjustment made pursuant to
                  this rule 8 and may at their discretion deliver to him a
                  revised Option certificate in respect of his Option or an
                  addendum to his Option certificate; and

8.2      For the purpose of rule 8.1, a reorganisation of ordinary share capital
         means any capitalisation issue or rights issue or any consolidation,
         subdivision or reduction of capital.

9.       CHANGE OF CONTROL ETC

9.1      If as a result of a general offer to shareholders in the Company (or
         any of them) any company obtains control of the Company, the Directors
         shall as soon as reasonably practicable notify every Option holder. The
         entitlement of Option holders to exercise their Options shall not be
         altered (save as may be provided elsewhere under these Rules) unless
         the Directors shall resolve within the period commencing six months
         prior to the date on which any company obtains control of the Company
         and ending three months thereafter that:

         9.1.1    all Options shall lapse on a date to be specified by the
                  Directors; and/or

         9.1.2    any or all of the conditions to which exercise is subject are
                  to be waived; and/or

                                       12
<PAGE>   13

         9.1.3    any limits on exercisability imposed pursuant to rule 6.1 are
                  to be waived.

              If the Directors so resolve, the Directors shall as soon as
reasonably practicable notify every Option holder of such resolution PROVIDED
ALWAYS that no Option shall lapse and cease to be exercisable by virtue of this
rule 9.1 until the later of (a) the date on which any company obtains control of
the Company and (b) one month after the date on which the notification is
despatched to Option holders in accordance with this rule 9.1.

9.2      If any person:

                  (a)       either alone or together with any person acting in
                            concert with him has obtained control of the Company
                            as a result of a general offer to shareholders in
                            the Company (or any of them) or otherwise; or

                  (b)       having such control makes a general offer to acquire
                            the whole of the issued share capital of the company
                            (other than that which is already owned by him and
                            whether or not excluding that which is already owned
                            by any person acting in concert with him)

              the Directors shall as soon as reasonably practicable notify every
Option holder. The entitlement of Option holders to exercise their Options shall
not be altered (save as may be provided elsewhere under these Rules) unless the
Directors shall resolve within the period commencing six months prior to the
date on which such person obtains control of the Company or (as the case may be)
makes such a general offer and ending three months thereafter that:

         9.2.1    all Options shall lapse on a date to be specified by the
                  Directors; and/or

         9.2.2    any or all of the conditions to which exercise is subject are

the Company or (as the case may be) makes such a general offer and (b) one month
after the date on which the notification is despatched to Option holders in
accordance with this rule 9.2.

9.3      If at any time before an Option has lapsed any person becomes entitled
         or bound to acquire shares in the Company under sections 428 to 430F
         (inclusive) of the Companies Act 1985 the Directors shall as soon as
         reasonably practicable notify every Option holder and each Option shall
         (subject to the

                                       13
<PAGE>   14

         provisions of these Rules) be exercisable at any time when that person
         remains so entitled or bound and upon the expiration of that period to
         the extent that the Option is not then exercised it shall lapse and
         cease to be exercisable.

9.4      If at any time any or all of the issued share capital of the Company
         shall be:

         9.4.1    admitted to trading on the Alternative Investment Market of
                  the London Stock Exchange or any market which is a successor
                  thereto;

         9.4.2    traded under Rule 26 of the Stock Exchange Yellow Book or

         the entitlement of Option holders to exercise their Options shall not
         be altered (save as may be provided elsewhere under these Rules) unless
         the Directors shall resolve in the period commencing six months prior
         to the date on which the shares are first admitted to trading, traded
         or admitted to the Daily Official List (as the case may be) and ending
         three months after such date that:

         9.2.1    all Options shall lapse on a date to be specified by the
                  Directors; and/or

         9.2.2    any or all of the conditions to which exercise is subject are

         notification is despatched to Option holders in accordance with this
         rule 9.5.

9.6      In the event of notice being given to holders of Shares of a resolution
         for the voluntary winding-up of the Company, the Directors shall as
         soon as reasonably practicable notify every Option holder and all
         Options shall immediately lapse and cease to be exercisable upon the
         commencement of the winding-up of the Company.

10.      ADMINISTRATION AND AMENDMENT

         in any respect.

10.2     In any matter in which they are required to act hereunder the Auditors
         shall be deemed to be acting as experts and not as arbitrators and

10.3     The cost of the implementation and operation of the Scheme (including
         but not limited to the costs relating to the issue of Shares upon the
         exercise of Options) shall be borne by the Company.

         Company, shall be delivered to the Company or sent by pre-paid
         first-class post to the Secretary at its registered office for the time
         being or such other place as the Company may notify from time to time,
         and, if to an Option holder, shall be delivered personally or sent by
         first-class pre-paid post to the Option holder at his risk at the
         address which he shall give to the Company for this purpose, or,
         failing any such address, his last-known place of abode and shall be
         deemed to have served upon delivery if delivered, or at the expiration
         of twenty four hours after posting, if posted, as aforesaid. No notice
         to the Company shall take effect unless the same shall have been

<PAGE>   16

         issue of sufficient shares for the purposes of the Scheme to satisfy
         the exercise in full of all Options for the time being capable of being
         exercised.

10.7     In the event of any dispute or disagreement as to the interpretation of
         the Scheme or of any regulation or procedure or as to any question or

         in their absolute discretion think fit and the decision of the
         Directors shall (except as regards any matter required to be determined
         by the Auditors hereunder) be final and binding upon all persons.

10.8     The Directors may at any time (without prejudice to the rights of
         Option holders under subsisting Options) suspend or terminate the
         operation of this Scheme.

10.9     The Scheme shall be governed by English Law.

10.10    If an allotment of Shares is made to satisfy an exercise of an Option

         months after the date of allotment of such shares.

          GENEVA TECHNOLOGY LIMITED UNAPPROVED SHARE OPTION SCHEME 1998

                               EMPLOYEE GUIDELINES

This document provides guidelines to the Geneva Technology Limited Unapproved
Share Option Scheme 1998, but legal interpretation of a share option grant is
solely dependent on the official Rules of the Scheme provided at the time of the
grant and on the Articles of Association of the Company. These guidelines do not
have any legal significance and do not form part of the official Rules.
Employees may wish to take independent legal or financial advice on the Scheme.

In the following guidelines, words importing the masculine gender shall also
include the feminine gender.

A.       GENERAL

1.       The Company has set up an "Unapproved" Share Option Scheme for
         employees. "Unapproved" in this sense means that the scheme does not
         fall within the Inland Revenue approved share option scheme regime.
         While unapproved schemes do not enjoy the same tax advantages as
         approved schemes, they do provide considerably greater flexibility of
         operation. The company may introduce additional share option schemes in
         the future.

2.       A share option scheme enables participating employees to buy shares
         ("exercise options") in the Company in the future at a pre-determined
         price. There is a binding obligation on the Company to sell but not on
         the employee to buy. The pre-determined price will be fixed at least
         once a year by the Company's Auditors and will be known at the time of
         the grant of the options.

3.       The Company's intention is that over a period of time the value of
         shares will rise and the participants can at some stage in the future
         realise an immediate risk free profit, subject to tax liabilities as
         referred to later. If the shares decrease in value the participant is
         not under an obligation to exercise any of the options.

4.       The share option scheme will be administered by the Directors of the
         Company, and details of the Scheme are subject to change at the
         discretion of the Directors.

B.       THE OPTIONS

1.       GRANT OF OPTIONS

1.1      There should be no tax liability on the grant of options.

1.2      The employee pays pound 1 for the option and this payment will not be
         refundable nor will it be deemed to be a payment on account of the
         eventual price for the shares.

2.       OPTION TERMS AND VALUATION

2.1      Options must be exercised no later than 7 years after they are granted.

2.2      Options will be offered from time to time as determined by the
         Directors. The option price (the price to be paid for the shares at the
         later date of exercising the options) will be determined on the date of
         offer. The option price will be an amount equal to the market value

<PAGE>   18

                  (as determined by the Company's Auditors) of a share on the
                  date on which the offer of options is made.

                  Once the shares are publicly listed the option price will be
                  the middle market quotation for the Company's shares during a
                  period preceding the offer of options as determined by the
                  Auditors.

2.3      The procedure for granting options is that the Directors will invite
         employees selected at their discretion to apply for options over a
         specified number of shares on terms set out in the invitation letter.
         If the employee wishes to apply for the options, he returns a signed
         acceptance form together with a cheque for pound 1 payable to the
         Company. The Directors will then consider the applications and at their
         discretion formally grant options on the terms specified.

3.       ENTITLEMENT TO EXERCISE

3.1      Under the Scheme the participant will generally be entitled to exercise
         options on the basis of the following rules (referred to as the
         'vesting schedule'):-

         At the end of the first twelve months following the date of grant of
         the options (or 12 months from the date of starting with the Company
         whichever is the sooner), 25% of the shares under option. Thereafter,
         the remaining 75% on the basis of 2 1/12% of the shares under option
         for each completed month of employment. The full entitlement will
         therefore have vested by the end of 4 years from the date of grant. The
         precise details of the vesting schedule will be set out on the Option
         Certificate itself.

         The vesting arrangement for particular employees or option grants may
         differ from this formula at the Directors' discretion.

4.       CEASING TO BE AN EMPLOYEE OF THE COMPANY

4.1      If a participant ceases to be an employee of the Company, his options
         will normally lapse immediately.

4.2      In some circumstances such as ceasing to be an employee by reason of
         injury, redundancy, retirement, transfer of the Company's business or
         other exceptional circumstances at the Directors' discretion, the
         participant may exercise his options, to the extent that they has
         vested, provided such exercise occurs within three months of the
         participant ceasing to be an employee.

4.3      Within three months of the employee leaving, or within three months of
         options having been exercised if this is later, the Company will be
         entitled to purchase any of the participant's shares allotted under the
         Scheme at fair value in accordance with the Articles of Association.

5.       TAX ON EXERCISE OF OPTIONS

         The following points regarding tax are based on current tax law and may
         be subject to amendment by future legislation. They are intended for
         general guidance only and should not be read as a definitive guide to
         an individual's particular tax liability:

5.1      An INCOME TAX LIABILITY arises when the participant exercises a share
         option. This is based on the market value of the shares when acquired
         less the option price for the shares. The taxable amount is treated as
         if it were additional income and is added to an employee's earnings for
         the year. A liability to tax will arise on any gain even if there is no
         disposal of the shares acquired.

5.2      Under certain circumstances, the Company may be liable to pay any
         income tax liability, which does arise, under the PAYE scheme. For this
         reason, the participant is required to indemnify the Company for any
         PAYE liability which may arise at the point of exercise.

         You may also be aware that all options issued under unapproved share
         option schemes since 6 April 1999 also attract a National Insurance
         contribution ("NIC") liability for both employers

<PAGE>   19

         and employees at the time of exercise. For this reason, the participant
         is required to indemnify the Company for any employee's NIC liability
         which may arise.

         In addition, the government has announced recently that the legislation
         in relation to employer's NICs on the exercise of options is changing,
         such that the burden of employer NICs may be passed to the employee.
         You will be required to indemnify the Company in respect of employer's
         NICs in addition to the PAYE income tax and employee's NICs which are
         payable on the exercise of the option (and certain other events), if
         the changes are made law. The grant of options is being made subject to
         this condition.

         Before a participant can exercise his option he may therefore be
         required by the Company to:

               either pay an amount equal to the Company's reasonable estimate
                  of the PAYE liability and employee's NICs and employer's NICs
                  which the Company will have to pay over to the tax
                  authorities;

              or provide the Company with a Power of Attorney enabling the
                  Company to sell some of the shares which the participant is
                  acquiring in order to meet these PAYE and NIC costs.

              If the reasonable estimate is too low, the Company will be
                  entitled to claim the balance from the employee later; if the
                  reasonable estimate is too high, the Company will pay the
                  excess back to the employee.

              Employees who are subject to higher rate income tax should not be
                  exposed to any employee NICs because their income should be
                  above the upper earnings threshold for employee's NICs (pound
                  26,000 in 1999/00).

5.3      The Application Form contains in addition a more general indemnity
         under which an applicant agrees to indemnify the Company against any
         tax or social security contributions payable by an employee in relation
         to the option. This indemnity might for example apply if the employee
         releases his option rights for a cash sum or if an employee were
         working overseas and foreign taxes applied to the option.

5.3      The Company will endeavour on public listing or take-over to ensure
         that a participant can dispose of sufficient shares to satisfy any tax
         liability arising.

6.       TAX ON SHARES SOLD

6.1      Any shares sold to a person other than the Company should be subject to
         normal CAPITAL GAINS TAX (CGT) rules. The base cost for CGT purposes
         will be the aggregate of:

                  (a) the price paid for the shares by the participant

                  (b) the amount of the gain which was subject to a charge to
         Income Tax when the option was exercised.

6.2      If the exercise of the options and the disposal are more or less
         contemporaneous there should be little or no charge to CGT. If the
         shares are retained for a period and subsequently sold at a gain, it
         may be possible to reduce or eliminate any liability to CGT by use of
         the annual exemption from CGT (currently pound 7,200).

6.3      The tax rules become significantly more complicated if the shares are
         sold to the Company rather than to other persons or to an Employee
         Benefit Trust, which may be set up in the future anyway in order to
         help alleviate this more onerous tax treatment. Many factors can effect
         the eventual tax treatment where the Company is the purchaser so the
         details of the tax treatment are not set out here. However, as and when
         circumstances arise where such a purchase by the Company may be
         necessary, then the Company will endeavour to minimise the overall
         liability to tax, both for the Company and the individual.

7.       RESTRICTIONS ON SHARES HELD

         7.1      Until such time as shares in the company are publicly listed,
                  employees who wish to sell any of the shares which they have
                  purchased by exercising their options under the Scheme MUST
                  first offer their shares a) to the Company or an Employee
                  Benefit Trust (if such is established) and b) to existing
                  shareholders, at the fair value determined by the Auditors in
                  accordance with the Articles of Association.

C.       OTHER

8.       Options cannot be transferred to anyone else except on death of a
         participant when his personal representatives may exercise any options
         within twelve months of death.

9.       In the event of any reorganisation of share capital the Directors may
         make such adjustments as they think appropriate without prejudice to
         the value of any options.

10.      Although participants will not technically be shareholders in the
         Company until they have exercised options, they will be provided with a
         similar level of information as that required to be given to actual
         shareholders. For example all participants will be supplied with at
         least a synopsis of the Company's annual accounts and report together
         with an indication of the current value of the shares. Upon exercising
         their options, participants will have the full voting rights of other
         shareholders.
