<PAGE>   28



         as provided in Part B of Article 7 by the occurrence of any Force
         Majeure mentioned in sub-paragraph (b) of Article 14.1 whether
         affecting NAPOCOR or HOPEWELL.

14.3     PROCEDURE. The party invoking Force Majeure shall:

         (a)      notify the other parties as soon as reasonably possible by
                  telex or cable of the nature of the Force Majeure and the
                  extent to which the Force Majeure suspends the affected
                  party's obligations under this Agreement; and

         (b)      resume performance of its obligations as soon as possible
                  after the Force Majeure condition no longer exists.

         Date the parties will meet to discuss a revised timetable for the
         completion of the Project indicating the proposed completion dates of

         period in excess of 180 days and such Force Majeure is mentioned in
         sub-paragraph (b) of Article 14.1 the provisions of Article 8.5 shall
         apply.

         causes material damage to the Project or the Power Station and such
         event or such damage would not ordinarily be insured against by NAPOCOR
         then HOPEWELL shall not be obliged to reinstate the Power Station, or,
         as the case may be, complete the building of the same, until the
         parties hereto have agreed upon the terms for such reinstatement or
         completion in a manner which will ensure that HOPEWELL's economic

                         ELECTRICITY DELIVERY PROCEDURES


1.       Definition

         "Downtime" means the seventy-three (73) days per Unit per year allowed
         to HOPEWELL by NAPOCOR to allow HOPEWELL to undertake the normal
         inspection, maintenance, repair and overhaul Provided that the amount
         of Downtime for the Power Station shall, in any year, be calculated by
         reference to that aggregate allowance of one hundred and forty six
         (146) days for both Units.

         "Forced Outage" is defined as the inability due to the fault of
         HOPEWELL to meet Contracted Capacity when requested by NAPOCOR (other
         than as a result of any faults in or failure of the power transformers
         or high voltage switchgear) Provided that any failure to meet the
         Contracted Capacity as a result of a reduction in the Availability of
         the Power Station as a result of Downtime or as a result of the Power
         Station commencing generation after a period of non generation shall
         not be Forced Outage.

2.       Measurement of Power Generated

         Measurement of power generated transferred to NAPOCOR shall be made at
         the high voltage side of the main power transformer.

3.       Notice in Change of Output

         Specific procedures for notifications of power requirements shall be
         agreed between HOPEWELL and NAPOCOR prior to the Unit Completion Date
         in respect of Unit 1. Subject to such procedures, the outputs of the
         Units shall be as required by the system controller from time to time,
         provided that changes in output requested by the system controller
         remain within the Specifications and the Operating Parameters.

4.       NOTICE OF DOWNTIME

         NAPOCOR shall prepare annual, monthly and weekly systems operating
         plans and in so doing shall coordinate with HOPEWELL to agree on
         Downtime. NAPOCOR shall grant HOPEWELL allowable Downtime to undertake
         all regular inspection and maintenance in accordance with the
         manufacturer's recommendations.

         HOPEWELL will be allowed a total of 73 days per Unit per year
         (calculated on the basis of an aggregate of one hundred and forty six
         (146) days for both Units) Downtime for normal inspection, maintenance,
         repair and overhaul. If in any year total available period of Downtime
         is not utilised the excess shall be carried forward and added to the
         allowance for the next year.



                                       49
<PAGE>   53

         HOPEWELL will plan with NAPOCOR to ensure that as far as practicable,
         Downtime is undertaken at times to cause minimum disruption to the
         NAPOC power supply.

5.       Notice of Required Electricity

         Whilst the annual, monthly and weekly system operating plans will be
         prepared by NAPOCOR in consultation with HOPEWELL, it is agreed that
         the weekly plan for the following seven days will be the control plan
         and will be that plan referred to as "normal operation plan".

6.       Normal Operations

         Normal operations of the Units are as defined below:

         (a)      Operating in accordance with the weekly normal operation plan
