                  and (ii) shall not be relieved of its obligation to make
                  payments of Capacity Fees as provided in Clause 11.01 by the
                  occurrence of any Force Majeure mentioned in sub-paragraph (b)
                  of Clause 16.01 whether affecting NAPOCOR or HOPEWELL.

         16.03    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.

         16.04    If Force Majeure applies prior to the Completion Date the
                  parties will meet to discuss a revised timetable for the
                  completion of the Project and if the Force Majeure has applied
                  for a period in excees of 180 days and such Force Majeure is
                  mentioned in sub-paragraph (b) of Clause 16.01 the provisions
                  of Clause 17.01 shall apply.

         16.05    If Force Majeure applies by the occurrence of any Force
                  Majeure mentioned in sub-paragraph (a) of Clause 16.01 during
                  the Co-operation Period the Co-operation Period shall be
                  extended by a period equal to that during which the effect of
                  the Force Majeure applies provided that if such effect applies
                  for a period in excess of 180 days the parties hereto will
                  meet to discuss the basis and terms upon which the
                  arrangements set out in this Agreement may be continued.

         16.06    The parties hereto will consult with each other and take all
                  reasonable steps to minimize the losses of either party
                  resulting from Force Majeure.

         16.07    If any event of Force Majeure occurs which causes 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 return on its investment is substantially
                  maintained and not prejudiced in any material way and NAPOCOR
                  agrees that it shall promptly, and in good faith, enter into
                  discussions with HOPEWELL to reach such agreement.

17.      Buyout

         17.01    If the circumstances set out in Clause 7.05, Clause 8.07,
                  Clause 16.04, Clause 16.07 or Clause 18 arise or if, not
                  earlier than 5 years after the Completion Date NAPOCOR gives
                  not less than 90 days notice to HOPEWELL that either it
                  wishes to close the Power Station or it wishes to move the
                  gas turbines to elsewhere in the Philippines or if, NAPOCOR
                  has failed to ensure the due payment of any sum due hereunder
                  within three months of its due date then, upon HOPEWELL
                  giving to NAPOCOR not less than 90 days notice requiring
                  NAPOCOR to buyout HOPEWELL or, as the case may be, NAPOCOR
                  giving not less than 90 days notice requiring HOPEWELL to
                  sell out to NAPOCOR, NAPOCOR shall purchase all HOPEWELL's
                  right, title and interest in and to the Power Station and
                  thereupon all HOPEWELL's obligations hereunder shall cease.

         17.02    In respect of any transfer of the Power Station pursuant to
                  Clause 17.01 the provisions of Clause 14 (other than Clauses
                  14.01 and 14.02) shall apply thereto.

         17.03    Subject to Clause 17.04, the purchase price in dollars,
                  payable pursuant to Clause 17.01 will be the total amount of
                  the Capacity Fees payable to HOPEWELL pursuant to Clause
                  11.01 until the Transfer Date upon the assumption that the
                  Contracted Capacity during each year of the Co-operation
                  Period for such period is equal to the lower of the
                  Contracted Capacity last nominated by HOPEWELL and the
                  Nominal Capacity and the resulting figure discounted to its
                  value on the date of completion of the buyout by applying a
                  discount rate equal to the last published Commercial Interest
                  Reference Rate for dollars published by the Organization for
                  Economic Cooperation and Development Provided that no buyout
                  may take place without the consent of HOPEWELL if the
                  purchase price calculated as above is not positive.

         17.04    If the provision of Clause 17.01 apply prior to the
                  Completion Date, the purchase price payable shall be an
                  amount equal to the aggregate of all the costs, expenses and
                  liabilities incurred by HOPEWELL in connection herewith as
                  estimated by an independent accountant jointly appointed by
                  both parties and subject to a maximum amount of $30,000,000
                  plus an amount equal to ten percent (10%) of such aggregate
                  provided such additional amount shall not be payable if the
                  provisions of Clause 17.01 are applicable pursuant to Clause
                  16.04.

         17.05    Completion of a buyout pursuant to Clause 17.01 shall take
                  place on the date of the expiry of the notice specified
                  therein at


                                       25
<PAGE>   29

                  which time NAPOCOR will pay to HOPEWELL the purchase price
                  calculated in accordance with Clause 17.03 or, as the case
                  may be, Clause 17.04 and payable in dollars and HOPEWELL
                  shall warrant that following such buyout the Power Station
                  shall be free from any lien or encumbrance created by
                  HOPEWELL.

         17.06    In the event that the provisions of Clause 17.01 apply
                  pursuant to Clause 16.04 then there shall be deducted from
                  the sum payable pursuant to Clause 17.04 an amount equal to
                  the value, if any, of any insurance proceeds received by
                  HOPEWELL in respect of the event leading to the operation of
                  the provisions of Clause 16.04.

18.      Change in Circumstances

         In the event that as a result of any laws or regulations of the
         Republic of the Philippines, or any agency or other body under the
         control of the Government of the Republic of the Philippines or any
         regional or municipal authority thereof, coming into effect after the
         date hereof, or as a result of any such laws or regulations (including
         any official interpretation thereof which HOPEWELL has relied upon in
         entering into this Agreement) in force at the date hereof being
         amended, modified or repealed or as a result of an increase in the
         cost of insurances or inability to renew insurances (unless such
         increase is due solely to HOPEWELL's prior performance in the
         operation of the Power Station) the interest of HOPEWELL in the Site,
         the Project or the Power Station and/or HOPEWELL's expectation of its
         economic return (net of tax or other imposition) on its investment is
         materially reduced, prejudiced or otherwise adversely affected
         (including, without limitation, any restriction on the ability to
         remit funds in dollars outside of the Philippines) then the parties
         hereto shall meet and endeavour to agree amendments to this Agreement
         and if after 90 days no such agreement has been reached the provisions
         of Clause 17.01 shall apply.

19.      Benefit of Agreement

         19.01    NAPOCOR may not assign or transfer all or any part of its
                  rights, benefits or obligations hereunder Provided that this
                  Clause shall not prevent NAPOCOR from merging or consolidating
                  with any other company which is wholly owned by the Republic
                  of the Philippines where the surviving entity adopts and
                  becomes fully liable to perform NAPOCOR's obligations
                  hereunder.

         19.02    HOPEWELL may not, subject to Clause 19.03, transfer all or any
                  of its obligations hereunder but may, for the purposes of
                  arranging or rearranging finance for the Project, assign or


                                       26
<PAGE>   30
                  transfer to any person providing finance to the Project all or
                  any part of its rights and benefits hereunder but not its
                  obligations and NAPOCOR shall duly acknowledge any such
                  assignment or transfer of which it is given notice.

         19.03    The importation into the Philippines of all equipment for the
                  Project and all other work in connection with the Project
                  which necessarily has to be performed in the Philippines and
                  which HOPEWELL agrees to be responsible for hereunder shall
                  be carried out by HOPEWELL PHILIPPINES which shall undertake
                  to perform HOPEWELL's obligations to perform such work and in
                  consideration of which NAPOCOR shall pay fees as provided in
                  Clause 11; HOPEWELL PHILIPPINES, in carrying out such work and
                  receiving such fees shall act on its own behalf and for its
                  own benefit, and not as an agent or representative of
                  HOPEWELL. For such purpose, HOPEWELL, NAPOCOR and HOPEWELL
                  PHILIPPINES (whose participation HOPEWELL shall procure) shall
                  execute and deliver the Accession Undertaking, upon the
                  effectiveness of which HOPEWELL PHILIPPINES shall become a
                  party hereto without the need for any further action on the
                  part of HOPEWELL or NAPOCOR and the rights and obligations of
                  NAPOCOR and HOPEWELL under this Agreement shall be transferred
                  and amended in accordance with the terms of the Accession
                  Undertaking, as if HOPEWELL PHILIPPINES had executed this
                  Agreement as amended by the terms of the Accession
                  Undertaking.

20.      Warranty

         HOPEWELL hereby warrants that neither it nor its representatives have
         offered any government officer and/or NAPOCOR official or employee any
         consideration or commission for this Agreement nor has it or its
         representatives exerted or utilized any corrupt or unlawful influence
         to secure or solicit this Agreement for any consideration or
         commission; that HOPEWELL shall not subcontract any portion or portions
         of the scope of the work of the Agreement awarded to any official or
         employee of NAPOCOR or to the relatives within the third degree of
         consanguinity or affinity of NAPOCOR officials who are directly or
         indirectly involved in contract awards or project prosecution and that
         if any commission is being paid to a private person, HOPEWELL shall
         disclose the name of the person and the amount being paid and that any
         violation of this warranty shall constitute a sufficient ground for the
         recission or cancellation of this Agreement or the deduction from the
         contract price of the consideration or commission paid without
         prejudice to the filing of civil or criminal action under the
         Anti-Graft Law and other applicable laws against HOPEWELL and/or its
         representatives and NAPOCOR's officials and employees.

                  operated as follows:

                  -        Turbine preparation and     :       8 minutes per
                           up to synchronous                   start unit
                           speed

                  -        Synchronizing and loading   :       12 MW per minute
                           to full load under normal
                           condition, ramp increase
                           not greater than

         6.       Operation Mode

                  The Power Station shall be utilized as a despatchable peaking
                  and base load plant and be expected to be able to operate
                  seven (7) days per week, 24 hours per day.

         7.       Variation of Power Load

                  At any given load, it is estimated that the allowable load
                  change per unit should be not more than 4 MW per minute.

         8.       Emergency Starts

                  It is estimated that 10 minutes notice should be given for an
                  emergency start during which the loading rates should be
                  restricted to those shown in Item 5.

         9.       Heat Rates

                  greater than 12,300 BTU/KWH reckoned at full load condition
                  in


                                       36



<PAGE>   40
                  accordance with the Guarantee Tests described in the
                  Fourteenth Schedule. The Power Station will be tested to
                  establish the Guaranteed Plant Net Heat Rate of 12,300
                  BTU/KWH. If results of the Guarantee Tests show a plant net
                  heat rate greater than 12,300 BTU/KWH then HOPEWELL shall
                  endeavour to refurbish or rehabilitate the units or to
                  otherwise correct the units in order to achieve the Guaranteed
                  Plant Net Heat Rate. NAPOCOR shall not be obliged to pay the
                  Capacity and Energy fees for such period that the Tested Plant
                  Net Heat Rate at maximum continuous rating is equal to or more
                  than 13,500 BTU/KWH except as permitted below (including
                  permitted tolerances). In the event that the Tested Plant Net
                  Heat Rate exceeds 12,300 BTU/KWH at commissioning and Hopewell
                  declares the Power Station to be complete, then the
                  application of Section 5.2 Energy Fees of the Eighth Schedule
                  shall be based on the Tested Plant Net Heat Rate for such
                  period as HOPEWELL is unable to correct the Plant Net Heat
                  Rate.

                  The permitted step increase in the Guaranteed Plant Net Heat
                  Rate shall be no greater than 73.8 BTU/KWH after the lapse of
                  every average 6,000 EOH of the units up to 30,000 EOH and 123

5.       TERMS OF PAYMENT

         5.1      CAPACITY FEES.  Capacity Fees shall be computed on the basis
                  of the following formula:

         A  =  {[(BCR * CC)(1 - TFOH/Nh)] - [(y * 1.05)(BCR)(NC - CC)]}

         where:

         A        =        Total Capacity Payment in Dollars for the
                           Month

         BCR      =        Base Capacity Rate in $/KW/Month

         NC       =        Nominal Capacity, in KW

         TFOH     =        Total Forced Outage Hours

         Nh       =        Total No. of Hours in the Month

         CC       =        Contracted Capacity for the year, in KW

         y        =        variable

         The Base Capacity Rate shall be $5.02 KW/Month.

         The variable y is defined as follows:

                  if 0.95 NC < CC, then y  =  0
                             -
                  if CC < 0.95 NC, then y  =  1

         In the event there is Forced Outage due to accident,
         manufacturing defect, defects in materials or assembly or any
         other similar reasons other than fault or failure of the power
         transformers or high voltage switchgear, and rectification of
         the Forced Outage to restore normal operations has taken or
         can reasonably be expected to take a period in excess of 15
         days, then the formula for the calculation of Capacity Fees
         shall be as follows for the entire period of Forced Outage:


               A  =  (BCR x IC) (1 - TFOH/Nh)

         Where:

         CC       =       the Contracted Capacity in effect immediately
                          prior to the Forced Outage

         and,

         IC       =       CC less the capacity lost due to such Forced
                          Outage.

<PAGE>   54

         Provided that if HOPEWELL is unable to make available the Contracted
         Capacity for reasons which would have been Forced Outage but for the
         fact they relate to faults in or failure of the power transformers or
         high voltage switchgear and such failure continues for more than 30
         days thereafter the Capacity Fee shall be reduced by reference to the
         amount of capacity that HOPEWELL is so unable to make available and
         the Co-operation Period shall be extended by a period equal to the
         period for which such reduction is applicable.

         5.2      ENERGY FEES.  Energy Fees shall be computed on the
                  basis of the following formula:

                      L  =  (BER)  *  ED)  +  O(Vg - Vt)

         where:

         L        =       Energy Fees, in dollars and pesos

                               TESTING PROCEDURES


I.       GUARANTEE TESTS

         (1)      Purpose of the Guarantee Tests

                  To demonstrate to NAPOCOR that the Power Station generator
                  output and the Plant Net Heat Rate are in accordance with the
                  Specifications (the "Guarantee Tests").

         (2)      Test Conditions

                  (a)      All gas turbine generating units of the Power Station
                           will be tested by HOPEWELL and the weighted average
                           results compared to the Guaranteed Plant Net Heat
                           Rate and generating capacity described in the
                           Specifications.

                  (b)      The measuring points will be the fuel supply meters,
                           and the electricity billing meters.

                  (c)      The Power Station is to be tested when the units are
                           in clean condition and the tests will be conducted
                           within 100 hrs. of loaded operation of the unit, or
                           of cleaning, or as agreed between HOPEWELL and
                           NAPOCOR.

                  (d)      Throughout the Guarantee Tests, measurements will be
                           taken while the Power Station is operated at maximum
                           continuous rating ("MCR").

                  (e)      If HOPEWELL notifies NAPOCOR that the Power Station
                           is to be tested for partial completion (for example,
                           (100MW) then the test conditions above and the test
                           procedures below shall apply to such testing provided
                           that (i) in respect of generating capacity, HOPEWELL
                           shall only be required to achieve the minimum
                           capacity which is the object of the test and (ii) in
                           respect of the Tested Plant Net Heat Rate, a value in
                           excess of the Guaranteed Plant Net Heat Rate a value
                           in excess of the Guaranteed Plant Net Heat Rate shall
                           not mean a failure of the of the Guarantee Tests for
                           partial completion if, upon the weighted averaging of
                           the Tested Plant Net Heat Rate with the results from
                           the Guarantee Tests for plant


                                       64
<PAGE>   68
                           completion, such average Tested Plant Net Heat Rate
                           remains within the Guaranteed Plant Net Heat Rate.

                  (f)      If HOPEWELL has successfully completed a partial
                           completion test, then the final Guarantee Test for
                           plant completion shall only be in respect of those
                           units untested.

         (3)      Test Procedures

                  (a)      During testing, both NAPOCOR and HOPEWELL will make
                           every effort to maintain the frequency, load, power
                           factor and stator voltage steady and as near possible
                           to specified values.

                  (b)      Electrical power output will be measured by a three
                           phase integrating watt hour meter (the Billing
                           meter), calibrated at a laboratory approved by
                           HOPEWELL and NAPOCOR immediately prior to the tests.

                  (c)      Fuel flow will be measured by the volumetric flow
                           meter located on the fuel supply pipelines. The
                           meter will be calibrated by an aproved establishment
                           for the load range and calibration curves will be
                           produced for inspection.

                  (d)      All tests points are to be taken under steady state
                           conditions. Steady-state sonditions are assumed to
                           exist when the variation in gas turbine exhaust
                           temperatures and wheelspace temperatures reach a
                           minimum.

                  (e)      When the following fluctuations are exceeded the test
                           results shall be considered by both NAPOCOR and
                           HOPEWELL to determine whether they are acceptable or
                           not. The term "fluctuation" is intended to mean the
                           difference between the maximum or minimum value of a
                           variable for a single test point and average of the
                           values recorded for that variable at the test point.

                  (f)      The tests will be conducted using normal operating
                           fuel with specifications in accordance with the
                           Fourth Schedule. Fuel heating value and specific
                           gravity will be determined by a properly qualified
                           laboratory.

                  (g)      Test readings for the Guarantee Tests will be
                           recorded at ten minutes intervals during one hour
                           period after the units have achieved a steady state
                           condition.

                  (h)      Instrumentation

                           Instruments used to measure performance are all
                           panel instruments unless otherwise mentioned.

                                    Only those measurement items with an
                                    asterisk (see Table I) are required for the
                                    Guarantee Tests.

                           Instruments used to measure the quantities required
                           for the Guarantee Tests will be calibrated over
                           their expected operating ranges.

                           In addition other instruments will be monitored to
                           ensure the units are operated under steady state
                           conditions.

         (4)      Tolerance

                  Only output and heat rate at MCR are guaranteed with
                  tolerance.

                  The measuring tolerance values at MCR are as follows:

                  Tolerance of output        :       1.75%

                  Tolerance of heat rate     :       3.0%
