     Association of NGG and, effective upon execution of this Agreement, to the
     board of directors of NGG, the parties have agreed that the relationship
     between RECs (being the principal shareholders of NGG) and NGG should be
     regulated in the period prior to Flotation.

                                        RECs, NGG and NGC.

     the "REC Oversight Committee"      means the committee established pursuant
                                        to Clause 3.

                                        execution of this Agreement and 
                                        terminating upon the earlier of the
                                        Flotation or the Termination Date.

     "Termination Date"                 means the date on which directors of NGC
                                        cease to be directors of NGG and

          to a clause, sub-clause or schedule, as the case may be, of or to this
          Agreement;

          unless such contracts or commitments are conditional on Flotation;

     (c)  NGG shall procure that no matters relating to NGC (or its

          to the EGMs, will be carries out by NGC (or such subsidiaries);

          withholding its approval in any case.

          approval of the REC Oversight Committee, such committee shall not be
          entitled to withhold approval unless it has reasonable grounds for
          believing that implementation is likely adversely to affect the
          financial viability of NGC and/or NGG and if the REC Oversight
          Committee does withhold approval it shall provide NGC and NGG with a
          written statement giving details of the grounds for such belief; and
