5.2  The Company and each of the  Directors  undertakes in favour of Investec to
     execute or to use all reasonable endeavours to procure the execution of all
     such  documents  and to do or procure  the doing of all such  things as may

     AIM Rules, the FSMA and the Criminal Justice Act 1993.

5.4  The  Company  and each of the  Directors  undertakes  promptly  to  provide
     Investec  or  procure  (so far as he is able) that  Investec  is as soon as
     practicable   following  a  request  from   Investec   provided   with  all
     information,  confirmations  and evidence  which  Investec  may  reasonably
     require for the proper performance of its duties hereunder and/or as may be

     and  accurate  in all  material  respects  and not  materially  misleading.
     Furthermore,  if anything occurs within a reasonable time thereafter  which
     renders any such information,  confirmation,  evidence and/or statements of
     opinion  untrue or inaccurate or  misleading in any material  respect,  the
     Company will as soon as practicable notify Investec and take all reasonable
     steps  necessary  to  amend  the  information,  confirmation,  evidence  or
     statement of opinion so as to rectify the matter.

5.5  The Company undertakes to Investec not to alter,  revise,  amend or release
     or agree to any alteration,  revision, amendment or release of any material
     terms or conditions of any service  agreements of senior  executives of the
     Company  without the prior written consent of Investec (such consent not to
     be unreasonably  withheld or delayed),  provided that this clause shall not
     restrict any revisions to the salary or benefits payable under such service
     agreements  which  have  been  approved  by the Board of  Directors  of the
     Company (or a duly appointed and authorised  remuneration  committee of the
     Board).

5.6  For so long as  Investec  shall  be  Nominated  Adviser  or  Broker  to the
     Company,  the Company shall not appoint any other nominated  adviser or any
     other broker.

               Company in or towards the  performance  of the role as  Nominated
               Adviser  hereunder  arising  by  reason of the  contents  of such
               document  or  material  not  being  accurate  or being  unfair or

     commencing on Admission (and notwithstanding  whether Investec is still the
     Company's  Nominated Adviser or not during that period),  where the Company
     is  proposing  to allot for cash new equity  securities  the voting  rights
     attaching to which would (together with any other  allotment(s) for cash of
     equity  securities  within the previous twelve (12) month period  following
     Admission  (or part thereof if  Admission  has taken place less than twelve
     (12) months  prior to such  allotment))  exceed ten per cent.  (10%) of the
     total voting rights attached to all the equity securities of the Company in
     issue,  it shall not (without  the prior  consent in writing of Investec or
     the prior approval by a Shareholder Majority):-

2.1  allot any of them on any  terms to a person  unless it has made an offer to
     each person who holds relevant shares or relevant  employee shares to allot
     to  him on the  same  or  more  favourable  terms  a  proportion  of  those
     securities  which is as nearly as practicable  equal to the proportion held
     by him of the aggregate of the issued relevant shares and relevant employee
     shares; and

2.2  allot any of those  securities  to a person  unless the period during which
     any such offer may be accepted (as referred to in paragraph  4.3 below) has
     expired or the Company has received  notice of the acceptance or refusal of
     every offer so made.

3.   The undertaking in paragraph 2 does not apply to:-

3.1  a  particular  allotment of equity  securities  if these are, or are to be,
     wholly or partly paid up otherwise than in cash;  and securities  which the
     Company  has  offered to allot to a holder of  relevant  shares or relevant
     employee  shares may be allotted  to him, or anyone in whose  favour he has
     renounced his right to their allotment, without contravening paragraph 2.2;
     or

                                                                         PAGE 19

     assignment of the right to their allotment, be held under an employee share
     scheme.

4.   In  relation  to an offer for the  purposes of  paragraph  2.1 above,  such
     offer:-

4.1  shall  be in  writing  and  shall  be made to a  holder  of  shares  either
     personally or by sending it by post (that is to say,  prepaying and posting
     a letter containing the offer) to him or to his registered  address [and if
     sent by post, the offer shall be deemed to be made at the time at which the
     letter would be delivered five (5) days following posting;

4.2  where  shares are held by two or more persons  jointly,  may be made to the
     joint holder first named in the Company's register of members in respect of
     the shares;

4.3  must state a period of not less than twenty one (21) days  during  which it
     may be accepted; and such offer may not be withdrawn before the end of that
     period;

     unless otherwise agreed in writing with Investec.

5.   Neither the Company nor any of the  Directors  shall make any claim against
     Investec or any  Indemnified  Person to recover any damage,  cost,  charge,
     expense,  loss or liability  which the Company or any of the  Directors may
     suffer or incur by reason of or arising out of the  exercise by Investec of
     its discretion as regards the consent referred to in paragraph 2 above.

6.   The  Company  undertakes  to  Investec  (for itself and as trustee for each
     Indemnified  Person) that it will indemnify and hold  harmless,  and at all
     times  keep each  Indemnified  Person  fully and  effectively  indemnified,
     against  all  losses,  claims,  expenses,  liabilities,  actions,  demands,
     proceedings and judgements whatsoever and all reasonable costs, charges and
     expenses  which Investec or any  Indemnified  Person may suffer or incur or
     which may be made against or incurred by Investec or any Indemnified Person
     in any jurisdiction by shareholders of the Company (or any of them) whether
     in their personal capacities,  by way of derivative action on behalf of the
     Company,  or  otherwise  (including,   but  without  limitation,  all  such
     reasonable  costs,  charges  and  expenses  including  any value  added tax
     thereon) as Investec or any Indemnified Person may pay or properly incur in
     responding to,  disputing any such actual or potential  actions,  claims or
     demands or in enforcing  the rights of Investec or any  Indemnified  Person
     under  paragraph 5 above and this  paragraph  6) and which in any such case
     arises  directly or indirectly out of or in connection with or results from
     or is attributable to the exercise by Investec of its discretion as regards
     the consent referred to in paragraph 2 above.

                                                                         PAGE 20
