            ----------     ----------

Section 3.2:  Delivery Rates

     (a)   HECO shall advise Chevron of its nominated rate of delivery for each
           month seventy-five days prior to the beginning of that month.

     (b)   Except to the extent that marine deliveries which are required by
           Chevron to meet the delivery requirement are prevented by the
           unavailability of HECO's Barbers Point tankage, beginning the 5th day
           of each month, at all times

                                                                          Page 1
<PAGE>
 
           during that month, Chevron's actual LSFO delivery rate, expressed in
           barrels per day, shall not fall below 85% of HECO's nominated volume
           to be delivered in the month of nomination as computed on a month-to-
           date ratable basis, found by multiplying the month of nomination's
           date by the nominated rate of delivery for that month, without the
           express prior agreement of HECO.

     (c)   Chevron and HECO shall make best efforts to coordinate their separate
           LSFO marine and pipeline deliveries into and out of HECO's storage
           tanks at Barbers Point to minimize operational difficulties and
           costs, including but not limited to tankage availability and vessel
           demurrage.

     (d)   Unless waived by HECO, Chevron's marine deliveries of LSFO shall be
           limited to 250,000 barrels, during:

           (i)  any ten day period, and

           (ii) any calendar month, except during months when Chevron's LSFO
                production facilities at Barbers Point are not operating.

     (e)   Unless waived by HECO, Chevron's actual LSFO deliveries during any
           month shall be limited to 200,000 barrels above HECO's nomination for
           that month.

     (f)   Unless waived by HECO, Chevron shall not deliver LSFO from its
           Barbers Point Refinery into HECO's storage tanks at Barbers Point
           during the fifteen (l5) days immediately preceding the scheduled
           delivery of a marine cargo from a vessel chartered by HECO or HECO's
           representative pursuant to the Facilities and Operating Contract
           between Chevron and HECO, as long as Chevron's LSFO can be delivered
           directly to HECO's storage tanks at Kahe, Waiau or Iwilei.

To provide the flexibility needed by Chevron to meet its obligations to HECO,
the source and type of crude oil and other raw material, the place of
manufacture, and the manufacturer of LSFO for delivery to HECO hereunder shall
be determined solely by Chevron.  The price of all LSFO delivered by Chevron to
HECO hereunder shall be determined in accordance with the terms of this Contract
regardless of where, how and by whom such LSFO is manufactured and regardless of
the type or source of crude oil or other raw materials used in its manufacture.

Section 5.3: Fees, Taxes, Assessments, Levies, etc.

In addition to all other amounts payable by HECO under this Contract, HECO shall
reimburse Chevron for all taxes, assessments, levies and imposts of whatsoever
kind or nature imposed on Chevron by any governmental or quasi-governmental
body, including without limitation the Hawaii General Excise Tax, the Hawaii
Environmental Response Tax, the Customs User Fee, the Federal Superfund Act and
oil spill liability fees, with respect to the sale of product under this
Contract or the receipt by Chevron of payments hereunder.  Notwithstanding the
foregoing, HECO shall not be required to reimburse Chevron for any tax measured
by or based on the net income of Chevron or for real property taxes.  To avoid
duplication of recovery, HECO shall not be required to reimburse Chevron under
this Section 5.3 for any item expressly mentioned by Platt's Oilgram Price
Report or Bunkerwire, or confirmed by Platt's in writing upon inquiry by either
Chevron or HECO, as being included in a price used to compute the billing price
under Section 5.1.

As of the effective date of this Contract, the governmental fees, etc. which are
currently in effect are the Hawaii General Excise Tax (4.167%), the Superfund
Petroleum fee ($0.097 per barrel), the Customs User Fee ($0.002 per barrel), and
the Hawaii Environmental Response Tax ($0.05 per barrel).  The Hawaii General
Excise Tax and the Hawaii Environmental Response Tax will be added to the
invoiced price.  The Superfund Petroleum fee and the Customs User fee will be
added to the LSWR Index of Section 5.1, since Platt's is not currently including
them in their published prices; these fees will not be added to the LA Bunker
index since Platt's is currently including them in their published prices.

Section 5.4: Rounding of Index Averages

All prices, index averages, adjustments thereto and other sums payable hereunder
shall be stated in the nearest thousandth of a dollar.

                         ARTICLE 7: Pipeline Delivery


Section 7:1: LSFO Delivery

Delivery of LSFO by pipeline shall be by one of the following methods.

         (a)   Chevron may deliver LSFO by pipeline from Chevron's Refinery into
               HECO's storage tanks at Barbers Point. Title and risk of loss of
               LSFO so delivered shall pass to HECO at the discharge flanges of
               Chevron's main pipeline feeder/blender pumps, P2027 and P2027A,
               where Chevron's piping systems a connect to HECO's LSFO delivery
               line leading to its storage tanks.

         (b)   Pursuant to the Facilities and Operating Contract between Chevron
               and HECO, Chevron may deliver LSFO by pipeline from Barbers Point
               (either Chevron's refinery or HECO's storage tanks) into HECO's
               storage tanks at Kahe, Waiau and Iwilei. Title and risk of loss
               of LSFO delivered from Chevron's refinery shall pass to HECO at
               the discharge flanges of the main pipeline booster pumps at
               Chevron's refinery. Title and risk of loss of the LSFO delivered
               from HECO's storage tanks shall remain with HECO at all times.

HECO agrees to pay a per barrel pipeline pumping fee for the LSFO delivered
under Section 7.1 (b).  The pipeline pumping fees and the measurement of the
pumped quantities are described in the Facilities and Operating Contract between
Chevron and HECO.

Section 7.2: Determination of Quality

The quality of LSFO delivered to HECO shall be determined on the basis of
samples drawn by Chevron in such a manner as to be representative of each
individual delivery.  Samples shall be drawn from Chevron's tanks prior to
delivery to HECO and shall be divided into four parts.  Separate parts shall be
provided to both HECO and Chevron to determine quality.  The remaining parts
shall be sealed and retained separately by Chevron and HECO.

The official heat content determination shall be based upon an average of
Chevron's and HECO's test results, provided that such results fall within the
ASTM reproducibility standard (currently 50,000 BTU per barrel) for Test D-240.
Chevron and HECO will make best efforts to evaluate heat content and exchange
results within 3 working days.  In the event of an unresolvable difference
between HECO and Chevron, HECO's sealed part shall be provided to an independent
laboratory for an official determination, which shall be final.  In cases of
disagreement or excessive delays in HECO's determination of heat content,
Chevron shall have the right to invoice the sale using a provisional heat
content of 6.2 MM BTU per barrel, with any required adjustments made after final
agreement is reached.  Chevron and HECO shall share equally the cost of
independent tests and determinations.

Section 7.3: Measurement of Quantity

Quantities of LSFO and line displacement stock delivered hereunder shall be
determined at the time of delivery by gauging Chevron's tanks before and after
pumping.  Measurements shall be taken by Chevron or Chevron's agent and
witnessed by HECO or HECO's agent.  However, at HECO's option, measurements may
be taken by a mutually agreed upon independent inspector at both Chevron's
refinery and HECO's receiving facilities.  If a mutually agreed upon independent
inspector is used, Chevron and HECO shall share equally the cost of such
independent inspections.  Volumes delivered hereunder shall be converted to 60
degrees F, using the latest revision of ASTM Table 6.

Section 7.4:  Disputes of Quality and Quantity

If Chevron or HECO has reason to believe that the quality or quantity of product
stated for a particular delivery per Sections 7.2 or 7.3 is incorrect, that
party shall within sixty days of the delivery date, present the other party with
documentation supporting such determination and the parties will confer, in good
faith, on the causes for the discrepancy and shall proceed to correct such
causes and adjust the quality and quantity, if justified, for the deliveries in
question.

                                                                          Page 5

                          ARTICLE 8: Marine Delivery

Section 8.1: Notification of Use of HECO's Barbers Point Tankage

Chevron shall provide HECO at least sixty days advanced notice of its planned
use of a specified volume of no more than 300,000 barrels of HECO's storage
capacity at Barbers Point and HECO shall set aside the requested storage
capacity for the purpose of accepting Chevron's marine delivery.  Chevron shall
then provide HECO with weekly updates on the anticipated arrival date of the
marine cargo.  If Chevron is unable to provide sixty days advance notice, HECO
will make all commercially reasonable efforts to provide Chevron with up to
300,000 barrels of storage capacity at Barbers Point.

Section 8.2: Delivery of Marine Cargo

Chevron may deliver the volume of LSFO specified in Section 8.1 from Chevron's
vessel directly into HECO's storage tanks at Barbers Point.  Chevron shall not
deliver more than the specified volume without prior written approval from HECO.
Chevron may not deliver LSFO from Chevron's vessels  directly into HECO's
storage tanks at Kahe, at Waiau or at Iwilei, without HECO's prior written
approval.  Such approval may be given during unusual circumstances, such as
pipeline maintenance.  Title and risk of loss of LSFO shall pass to HECO at the
flanges where Chevron's piping systems connect to HECO's  piping systems for
HECO's tankage at Barbers Point, Kahe, Waiau or Iwilei.

Section 8.3: Determination of Quantity and Quality

The quantity and quality of LSFO delivered by marine vessel shall be determined
in the manner specified in Sections 7.2, 7.3 and 7.4 of this Contract, except as
follows:

     (a) all measurements and samples shall be made and drawn by or under the
         supervision of an independent inspector, and the costs thereof shall be
         shared equally by Chevron and HECO.
     (b) volume shall be determined by gauging HECO's receiving tank(s) before
         and after pumping; and

     (c) samples to determine quality shall be drawn after the LSFO is
         discharged on Oahu.

Section 8.4:  Delayed Invoicing

Invoicing of marine deliveries of LSFO, in any ten day period, shall be limited
to ten times the average daily rate of HECO's nomination for the month against
which the marine delivery applies.


              ARTICLE 9: Line Displacement Stock and Blend Stock

Section 9.l:   Line Displacement Stock.

HECO shall purchase from Chevron whatever line displacement stock that is
required for Chevron to complete the deliveries of LSFO and that is received
into HECO's tankage at Kahe, Waiau and Iwilei.  The price of No. 2 diesel fuel
or No. 6 fuel oil used as line displacement stock shall be the then-current
pricing for the fuel comprising the line displacement stock in Chevron's supply
contract with HECO and HECO's affiliates, if such a supply contract is in
effect; otherwise its price shall be the then-current Honolulu posted price for
such fuel, less normally available discounts, if any, at the time of purchase.
The price of No. 5 fuel oil used as line displacement stock shall be the sum of
40% of the then-current No. 2 diesel fuel pricing and 60% of the then-current
No. 6 fuel oil pricing in Chevron's supply contract with HECO and HECO's
affiliates, if such a supply contract is in effect; otherwise its price shall be
the then-current Honolulu posted price for No. 5 fuel oil, less normally
available discounts, if any, at the time of purchase.  HECO's minimum purchase
obligation and Chevron's maximum purchase obligation set forth in Article 3
shall be reduced by each physical barrel of line displacement stock sold.

Section 9.2:   Blend Stock

In the event HECO desires to adjust the quality of its LSWR in its Barbers Point
tanks to meet the specifications of Article 4, Chevron shall supply the
necessary blend stock pursuant to Addendum 2.

                                                                          Page 6

line displacement stock sold will be prepared and dated following delivery and
shall be rendered from time to time each calendar month.  The invoices shall
also show as a separate item the estimated amounts of any reimbursements to
which Chevron is entitled pursuant to Section 5.3.

Section 10.2: Payments

Payments of such invoices shall be made in U.S. dollars.  Timing of payments for
sales and deliveries received shall be based upon the invoice issue date which
shall be the invoice date or postmarked mailing date of the invoice, whichever
is later, as follows:

     (a) Payment for a received invoice dated from the 1st through the 10th of a
         month is due on the 20th of the same month.
     (b) Payment for a received invoice dated from the 11th through the 20th of
         a month is due by the last day of the same month.
     (c) Payment for a received invoice dated from the 21st through the last day
         of the month is due on the 10th day of the following month.

Due dates are the dates payments are to reach Chevron.  If the due date falls on
a Saturday, the payment shall be made on the preceding business day.  If such
date falls on a Sunday or a holiday, payment shall be made the following
business day.

Section 10.3: Method of Payment

Payments shall be by bank wire transfer of immediately available funds to:

                           ARTICLE 11: Contingencies

Section 11.1: Definition of Contingency

As used in this Article 11, the term "contingency" means:

                (a) any event reasonably beyond the control of the party 
                    affected;

                (b) compliance, voluntary or involuntary, with a direction or
                    request of any government or person purporting to act with
                    governmental authority; excluding, however, any such
                    direction or request restricting or otherwise regulating
                    combustion of the LSFO to be purchased by HECO hereunder,
                    the effect of which restrictions or regulation upon the
                    parties' performance shall be governed by Section 11.5 of
                    this Contract;

                (c) total or partial expropriation, nationalization,
                    confiscation, requisitioning or abrogation or breach of
                    government contract or concession;

                                                                          Page 7
<PAGE>
 
                (d) closing of, or restriction on the use of, a port or
                    pipeline;

                (e) maritime peril (including but not limited to, negligence in
                    navigation or management of vessel, collision, stranding,
                    destruction, or loss of vessel), storm, earthquake, flood;

                (f) accident, fire, explosion;

                (g) hostilities or war (declared or undeclared), embargo,
                    blockage, riot, civil unrest, sabotage, revolution,
                    insurrection;

                (h) strike or other labor difficulty (whomever's employees are
                    involved), even though the strike or other labor difficulty
                    could be settled by acceding to the demands of a labor
                    group; or

                (i) loss or shortage of supply, production, manufacturing,
                    distribution, refining, transportation, delivery facilities,
                    receiving facilities, equipment, labor, material, power
                    generation or power distribution caused by circumstances
                    which the affected party is not able to overcome by the
                    exercise of reasonable diligence or which the affected party
                    is able to overcome only at substantial additional expense
                    in relation to the expected revenue, benefits or rights
                    related directly to this Contract.

Section 11.2:  Obligations to Sell

Chevron shall not be obligated to sell or deliver LSFO to the extent that
performance of this Contract is prevented, restricted or delayed by a
contingency which significantly affects Chevron's ability to supply, manufacture
or transport LSFO to HECO under this Contract from Chevron's U.S. West Coast and
Hawaiian refineries.  In such circumstances, deliveries of LSFO to HECO may be
reduced on a basis as equitable to HECO as to Chevron's and its affiliates'
other customers of crude and petroleum products, and Chevron shall not be
obligated to acquire additional crude or LSFO but to the extent that it does
acquire additional crude or LSFO, HECO shall be entitled to an equitable share
of the LSFO acquired or derived from the crude acquired, at a price to be agreed
from time-to-time.

Section 11.3:  Obligations to Purchase

HECO shall not be obligated to purchase, receive or use LSFO to the extent that
performance of this Contract in the customary manner is prevented, restricted or
delayed by a contingency.  In such circumstances, purchases from Chevron may be
reduced on any basis as equitable to Chevron as to HECO's other suppliers of
LSFO.

Section 11.4:  Price Effectiveness

If at any time any price determined under this Contract cannot be given effect
because to do so would violate a direction or request of any government or
person purporting to act with governmental authority, HECO and Chevron shall
attempt to agree on an alternate course of action, but failing agreement within
10 days the party adversely affected may suspend performance with respect to the
quantity of LSFO affected by the direction or request.

Section 11.5:  Combustion Specifications

To the extent that any governmental regulation requires combustion of LSFO
meeting more stringent specifications or permits combustion of LSFO meeting less
stringent specifications than those in Article 4, HECO and  Chevron shall
negotiate in good faith to agree on an alternative course of action that will
allow  HECO to comply with such regulation while purchasing the equivalent of
the full quantity of LSFO it would be required to purchase under Article 3, at a
price and on other terms and conditions that are fair to both parties.  Chevron
shall have no obligation to deliver LSFO meeting new specifications if it is not
available for purchase from third parties and Chevron cannot manufacture such
LSFO in existing facilities without new capital investment. If HECO and Chevron
do not agree on such an alternate course of action, then HECO may comply with
such regulation in any reasonable manner it chooses, including the option to
purchase from other sources for its plants located within the area in which such
regulation specifically applies, fuels which will enable HECO to comply with
such regulation. In such case, HECO's minimum purchase obligations and Chevron's
maximum supply obligations under Article 3 shall be reduced accordingly.

                                                                          Page 8
<PAGE>
 
To the extent HECO is unable to utilize fuel to be supplied by Chevron under
this Contract, but HECO does not purchase fuel which meets such requirements
from other sources in an amount equal to the amount by which deliveries under
this Contract are reduced, then purchases from Chevron may be reduced on any
basis as equitable to Chevron as to HECO'S other suppliers of similar fuel  oil.

Any adjustments in price pursuant to this Section 11.5 shall be governed by
Section 11.6, except that the adjustments shall apply to all LSFO delivered
which meets the new specifications.

Section 11.6: Effective Date

In the event of retroactive adjustments hereunder, the charge or credit to HECO
shall be computed and billed to HECO as soon as practical after the adjustment
is known.  In the event of retroactive changes which cause adjustments hereunder
after termination of this Contract, payment shall be made within 15 days after
receipt of written demand therefor by the other party.


Section 11.7:  Refining and/or Delivery Operations Ownership

Chevron's obligations under this Contract shall be contingent on Chevron's
continued ownership or operation of its refining or delivery facilities in
Hawaii or the U.S. West Coast.  Chevron shall have the right to terminate this
Contract in the event the ownership and operation of its refining and delivery
facilities in Hawaii and the U.S. West Coast are transferred to an entity other
than an affiliate.  Chevron shall give HECO 180 days' written notice.


                 ARTICLE 12: Effect of Suspension or Reduction

Section 12.1:  Notice of Suspension or Reduction

In the event of any suspension or reduction of sales and deliveries under
Article 11, Chevron shall not be obligated to sell and HECO shall not be
obligated to buy, after the period of suspension or reduction, the undelivered
quantity of LSFO which normally would have been sold and delivered hereunder
during the period of suspension or reduction.

Section 12.2:  Option to Terminate

If sales and deliveries are suspended under Article 11 for more than 180 days,
Chevron or HECO shall have the option while such suspension continues to
terminate its obligations to the other party under this Contract on 30-days'
written notice to the other party.

Section 12.3:  Prompt Notices

Any party which relies upon Article 11 shall give the other party prompt notice
thereof specifying the anticipated amount and duration of any suspension or
reduction of deliveries.  It shall also give prompt notice when it no longer
expects to rely on Article 11 and deliveries shall be reinstated subject to all
conditions of this Contract, unless this Contract has been terminated previously
under Section 12.2.

Section 12.4:  United States Currency

Nothing in Article 11 shall relieve HECO of the obligation to pay in full in
United States currency for the LSFO sold and delivered hereunder and for other
amounts due by HECO to Chevron under this Contract.

Section 12.5:  Substitute Suppliers

While deliveries are suspended or reduced by Chevron pursuant to Article 11, it
shall not be a breach of this Contract for HECO to buy from a supplier other
than Chevron the quantities of LSFO which Chevron does not deliver.  During this
period of time there will be no minimum volume requirements.  After any
suspension or reduction has ended, minimum and maximum volume requirements of
Article 3 for the annual period in which the suspension or reduction occurred
will be reduced in proportion to the ratio of the number of days within the
annual period during which no suspension or reduction was in effect, to the
number of days within the annual period.

                                                                          Page 9
<PAGE>
 
                   ARTICLE 13: Waiver and Non-Assignability

Section 13.1: Waiver

Waiver by one party of the other's breach of any provision of this Contract
shall not be deemed a waiver of any subsequent or continuing breach of such
provisions or of the breach of any other provision or provisions hereof.

Section 13.2: Non-Assignability

This Contract shall not be assignable by either party without the written
consent of the other, which shall not be unreasonably withheld, except that
either party may assign this Contract to any affiliate, provided that any such
assignment shall not release that party from any of its obligations hereunder,
and except that HECO may assign this Contract to the Trustee under its First
Mortgage Bond Indentures.  Chevron does not, by agreement to such an assignment,
waive any right it may have to terminate this Contract for any breach hereof
occurring at any time before or after any such assignment or release HECO of any
obligations arising under this Contract after any such assignment.  Following
any such assignment, no further assignment may be made without the consent of
Chevron.

Section 13.3: Definitions

In this Article 13 and Sections 11.2 and 11.7, "affiliate" shall mean any
corporation controlling, controlled by or under common control, with either
Chevron or HECO.  "Control" of a corporation shall mean ownership, directly or
indirectly, or at least 50% of the voting shares of such corporation.


                              ARTICLE 14: Default

If HECO or Chevron considers the other party to be in default of any obligation
under this Contract, such party shall give the other party notice thereof.  Such
other party shall then have 30 days in which to remedy such default.   If the
default is not cured, the other party may, without prejudice to any other right
or remedy of such party in respect of such breach, terminate its obligations
under this Contract, except for HECO's obligation to pay in full in United
States currency for the LSFO sold and delivered hereunder and for other amounts
due by HECO to Chevron under this Contract by 45 days notice to the party in
breach.  Any termination shall be without prejudice to accrued rights.  All
rights and remedies hereunder are independent of each other and election of one
remedy shall not exclude another.

In no event shall either party be liable for any indirect, consequential,
special or incidental damages of any kind whether based in contract, tort
(including without limitation negligence or strict liability), warranty or
otherwise.


                       ARTICLE 15: Conflicts of Interest

Conflicts of interest related to this Contract are strictly prohibited. Except
as otherwise expressly provided herein, neither party nor any director, employee
or agent of a party shall give to or receive from any director, employee or
agent of the other party any gift, entertainment or other favor of significant
value, or any commission, fee or rebate.  Likewise, neither party nor any
director, employee or agent of a party shall enter into any business arrangement
with any director, employee or agent of the other party (or any affiliate),
unless such person is acting for and on behalf of the other party,  without
prior written notification thereof to the other party.

In the event of any violation of this Article 15, including any violation
occurring prior to the date of this Contract which resulted directly or
indirectly in one party's consent to enter into this Contract with the other
party, such party may, at its  sole option, terminate this Contract at any time
and, except for obligations to pay in full in United States currency for the
outstanding payment obligations hereunder, shall be relieved of any further
obligation under this Contract.

Both parties agree to immediately notify the other of any known violation of
this Article.

                                                                         Page 10

                          ARTICLE 16: Applicable Law

This Contract shall be construed in accordance with, and all disputes arising
hereunder shall be determined in accordance with, the local law of the State of
Hawaii, U.S.A.


                ARTICLE 17: Public Utility Commission Approval

This Contract is required to be filed with the Hawaii Public Utilities
Commission ("PUC") for approval.  If in the proceedings initiated as a result of
the filing of this Contract, the PUC disapproves or fails to authorize the
recovery of the fuel costs incurred under this Contract through HECO's "Energy
Cost Adjustment Clause", HECO may terminate this Contract by 30 days written
notice to Chevron.

                                ADDENDUM NO. 3
Recovery of Worldscale Fixed Differential For Oil Pollution Liability Insurance

The price formula for LSFO in Section 5.1 of the Contract includes the component
"FREIGHT" that refers to a Worldscale 100 rate published in the current edition
of Worldscale which incorporates a Fixed Rate Differential to reflect the cost
of additional premiums for Oil Spill Liability Insurance on vessels carrying
Persistent Oils applicable to voyages having a destination in the U.S.A..
Chevron acknowledges that any vessel used to transport LSFO that is sold and
purchased under the Contract, including its components and the crude oil from
which the LSFO is derived, shall be required to possess oil spill liability
insurance coverage in the amount of $700 million.

The price formula component "FREIGHT" refers to an AFRA rate applicable to a
vessel size classification of LR-1, or Large Range 1.  This vessel
classification references tanker vessels ranging in size from 45,000 Long Tons
Deadweight to 79,999 Long tons Deadweight.  In order to derive an approximation
of the relationship between Deadweight and Gross Registered Tons for a nominal
vessel consistent with the mathematical average of this vessel size
classification, the average of two vessels that have transported LSFO or its
components to Hawaii in the recent past that are approximately equal to the
midpoint of the LR-1 range were referenced.  These vessels are described as
follows:

<TABLE>
<CAPTION>
 
        Name          Deadweight Tons (DWT)  Gross Registered Tons (GRT)
 
<S>                   <C>                    <C>
M/T London Spirit             62,097                   36,865
M/T London Victory            62,156                   36,865
 
Average                       62,127                   36,865
</TABLE>

The Worldscale 100 rate that is to be included in the computation of FREIGHT is
to be derived in the same manner as the following illustrative example
calculations:

1.  The Worldscale 100 rate in effect from February 19, 1995, shall include a
Fixed Rate Differential which shall be the sum of a. and b. and shall be
computed as follows:

     a. Fixed Rate Differential with respect to the additional insurance
        premiums For Basic $500 million coverage of Oil Pollution Liability
        Insurance on vessels carrying Persistent Oils to and from the U.S.A.

        Fixed Rate Differential  =  $0.27/GRT X 36,865 GRT
                                            62,127

                                 =  $0.160 per Metric Tonne

        For illustrative purposes, this rate may be expressed in U.S. dollars
per barrel as follows:

                                 =    $0.160/Metric Tonne
                                    6.75 barrels/Metric Tonne

                                 =  $0.024/barrel

     b. Fixed Rate Differential with respect to the additional insurance
        premiums for Excess $200 million coverage of Oil Pollution Liability
        Insurance on vessels carrying Persistent Oils to and from the U.S.A.

        Fixed Rate Differential  =  $0.2225/GRT X 36,865 GRT
                                              62,127

                                 =  $0.132 per Metric Tonne

        For illustrative purposes, this rate may be expressed in U.S. dollars
per barrel as follows:

                                 =    $0.132/Metric Tonne
                                    6.75 barrels/Metric Tonne
 
<PAGE>
 
                                 =    $0.020/barrel

The sum of which shall equal $0.2920 per Metric Tonne, or $0.044 expressed in
U.S. dollars per barrel.

2.   The AFRA Worldscale Points and their related Worldscale 100 rate applicable
for each calendar quarter are based upon an average of the three monthly AFRA
publications in the calendar quarter immediately preceding the calendar quarter
of the nominated month of delivery.  Therefore the relevant Fixed Rate
Differentials computed above should be applied as follows:

     A.   With respect to volumes of LSFO nominated during the three (3) months
of the quarter following a change in the published rate (typically February of
each year), the relevant Fixed Rate Differential to be included in the
computation of the price component "FREIGHT" shall be the sum of:
 
          50/90 multiplied by the Fixed Rate Differential computed prior to the
          rate change:

          and 40/90 multiplied by the Fixed Rate Differential computed using the
          revised rate:
 
     B.   With respect to volumes of LSFO nominated for subsequent months,
and continuing for so long as the Fixed Rate Differentials as set forth in
Worldscale Circular shall be applicable, the relevant Fixed Rate Differential to
be included in the computation of the price component "FREIGHT" shall be as
derived in part 1 above.

The volumes of CIFO, Diesel and Jet shown for 1997 shall also apply to any 
Extensions, unless otherwise revised.

     Section 3.2   Prior to the 15th day of each month, HECO shall give Seller a
forecast of each Buyer's monthly lifting of Diesel, CIFO and Jet from each
supply point   for each of the coming three months.  Each Buyer recognizes the
importance to Seller of reasonably accurate lifting forecasts because of
Seller's need to plan production and shipments.

     Section 3.3  Buyers' purchases and Seller's Deliveries of CIFO and Diesel
will occur in a ratable fashion throughout the year.  At the end of each
calendar year, Buyers' CIFO and Diesel purchase performance will each be
reviewed by Seller for ratability.

     i.   If upon review Buyers' volumes in any calendar quarter were less than
15% of the total minimum annual liftings for either CIFO or Diesel, a premium of
$0.42/barrel will be charged to Buyer for the difference between 15% of total
minimum annual liftings of that product and Buyers' actual liftings of that
product.

     ii.  If upon review Buyers' volumes in any calendar quarter were greater
than 35% of the total maximum annual liftings for either CIFO or Diesel, a
premium of $0.42/barrel will be
 
                                                                          Page 6

charged to Buyer for the difference between Buyers' actual liftings of that
product and 35% of total maximum annual liftings of that product.

     iii. Seller understands Buyers' jet fuel purchases will occur in a non-
ratable fashion and no ratability premiums will be applied to jet fuel
purchases.

The pricing of CIFO, Diesel and Jet includes applicable Superfund and Oil Spill 
Liability Trust Fund charges.

    Section 5.2  To provide the flexibility needed by Seller to meet its
obligations to Buyer, the source and type of crude oil and other raw material,
the place of manufacture, and the manufacturer of Oil for delivery to Buyer
hereunder shall be determined solely by Seller.  The price of all Oil Delivered
by Seller to Buyer hereunder shall be determined in accordance with the terms of
this Contract regardless of where, how and by whom such Oil is manufactured and
regardless of the type or source of crude oil or other raw materials used in its
manufacture.

    Section 5.3  In addition to all other amounts payable by Buyer under this
Contract, Buyer shall reimburse Seller for all taxes, assessments, levies and
imposts of whatsoever kind or nature imposed on Seller by any governmental or
quasi-governmental body, including without limitation the Hawaii General Excise
(Gross Income) Tax, the Hawaii Environmental Response Tax and Hawaii Liquid Fuel
Tax, where applicable, with respect to the execution or performance of this
Contract or the receipt by Seller of payments hereunder.  Notwithstanding the
foregoing, Buyer shall not be required to reimburse Seller for any tax measured
by or based on the net income of Seller or for real property taxes.  To avoid
duplication of recovery, Buyer shall not be required to reimburse Seller under
this Section 5.3

                                                                         Page 12

for any item expressly mentioned by Platt's or Bunkerwire, or confirmed by
Platt's or Bunkerwire in writing upon inquiry by either Buyer or Seller, as
being included in a price used to compute PD1, PD2, PF or PJ under Section 5.1.
As of the Contract execution date, the Superfund Petroleum fee of the Superfund
Revenue Act of 1986 is the only tax, assessment, levy or impost implicitly
reimbursed to Seller through inclusion in the Platt's listings within DI, FI and
JI of Section 5.1.

    Section 5.4 Seller will draw representative samples of all Diesel Delivered 
to buyer to determine the BTU content per Section 7.1.  If the BTU content per 
gallon of the representative sample falls within the range of 137,000 to 
141,000, no price adjustment will be made. If the BTU content per gallon is 
below 137,000, or above 141,000, the price charged for the Diesel Delivered to 
Buyer shall be adjusted by multiplying the price determined in Article V, by the
ratio of the actual heat content to 139,000 BTU.  Seller shall credit Buyer's 
account for overpayments and Buyer shall pay Seller for underpayments resulting 
from the BTU adjustments as soon as possible after the close of each month, but 
in no event later than 60 days after the close of a month. Such adjustments to 
either Buyer or Seller will be handled as separate credits or invoices and each 
individual invoice drawn during the month will not be corrected and reissued.


    Section 5.5  Seller will draw representative samples of each CIFO Delivery,
which will be used to determine the CIFO BTU content per Section 7.1.  If the
weighted average BTU content of the CIFO Delivered to Buyer during any half of
any annual period is less than 6.2 MM BTU per physical barrel, the price of such
CIFO delivered to Buyer during each month of that semiannual period shall be
adjusted by multiplying the CIFO price as determined by Section 5.1.ii. for each
month by a ratio of actual average heat content to 6.2 MM BTU and Seller shall
issue Buyer a credit for the difference between such aggregate and the adjusted
price.

    Section 5.6  All prices, adjustments thereto and other sums payable
hereunder shall be stated in the nearest thousandth of a dollar.

                                                                         Page 13

                                  ARTICLE VI
                                  DELIVERIES
    Section 6.1

    i.    Seller agrees to Deliver and MECO and HELCO agree to receive their Oil
          into their nominated barge, F.O.B. the HMT. The delivery rate on
          Diesel shall be 3,000 BPH minimum. The delivery rate on CIFO shall be
          1,600 BPH minimum. Seller agrees to make its best, reasonable efforts
          in operating its current CIFO delivery systems to Deliver CIFO into
          the nominated barge at a temperature above 120(degrees)F. Buyer
          acknowledges that the CIFO delivery temperature is determined by
          Seller's and HECO's scheduling of other fuels in Seller's pipeline,
          and hence cannot be guaranteed.

    ii.   When mutually agreed to, Seller may Deliver and MECO and HELCO may
          receive their Diesel into their nominated barge, F.O.B. Honolulu
          Harbor Piers 31 or 32. The delivery rate shall be 2,000 BPH minimum.

    iii.  When mutually agreed to, Seller may Deliver and MECO and HELCO may
          receive their Oil into their nominated barge, F.O.B. Barbers Point
          Piers 5 or 6. The delivery rate shall be 4,000 BHP minimum.

    iv    Seller and Buyer's agent or a mutually agreed upon independent
          inspector shall inspect the receiving barge cargo tanks to ensure that
          they contain only minimal remains of the previous cargo, before Seller
          will Deliver Oil to be terminaled per Article XI. Remains exceeding
          common commercial practice shall be removed by Buyer to protect the
          quality of the Delivered Oil. Buyer or Buyer's agent may remove the
          remains by any legal method at their disposal, including pumping the
          remains into Seller's slop tank at the HMT, if convenient to Seller.
          Seller shall have the right to charge Buyer for accepting remains if
          the quantity to be removed from any barge or the number of barges

                                                                        Page 14
<PAGE>
 
          requiring remains to be removed becomes excessive. Seller shall have
          the right to flush the receiving barge cargo tanks with a small
          quantity of Seller's Oil before loading the Delivered Oil.

    v.    Seller and Buyer's agent or a mutually agreed upon independent
          inspector shall take a representative sample of the oil in the barge
          cargo tanks, after Seller has delivered Oil into MECO's and HELCO's
          nominated barges. See Addendum 2 hereto for an overview on all
          sampling. This sample will be divided into two parts and dated. One
          part shall be labeled "Seller's Loaded Sample." One part shall be
          sealed and labeled "Buyer's Loaded Retain." These samples shall
          indicate the quality of the mixture of Delivered Oil and the previous
          cargo remains and will provide an early warning of any quality
          problems with the Received Oil as described in Section 11.3.

    Section 6.2  Seller agrees to Deliver and HT&B and YB agree to receive their
Diesel into their nominated vessel F.O.B. the HMT, Pier 31 or 32.  The delivery
rate shall be 175 BPH minimum.

    Section 6.3  Seller agrees to Deliver and HECO agrees to receive its Diesel
under either of the options below.

    i.   Seller will Deliver Diesel from the HDT into HECO's nominated tank
         truck at a delivery rate of 190 BPH minimum.

    ii.  Seller will Deliver Diesel from the Oahu P/L into HECO's storage at
         HECO's Waiau Power Plant, at a delivery rate of 1,000 BPH minimum.

    Section 6.4  Seller agrees to deliver and MECO and HELCO agree to receive
Jet at MECO's or HELCO's respective power plant truck unloading rack.

    Section 6.5  Seller agrees to Deliver and MECO-Molokai agrees to receive its
Oil into its nominated marine terminal at Kaunakakai Harbor, Molokai.  The
delivery rate shall be 1,000 BPH minimum.  Buyer will provide discharge
facilities through an independent third party; Seller has no responsibility to
procure discharge facilities on the island of Molokai.

                                                                         Page 15

    Section 6.6

    i.    For the Delivered Oil under Sections 6.1 and 6.2, care, custody,
          control, title and risk of loss shall pass to Buyer as the Oil passes
          the flange connecting the cargo hose of the Buyer's nominated barge or
          vessel and Seller's pipeline.

    ii.   For the Delivered Diesel under Section 6.3.i., care, custody, control,
          title and risk of loss shall pass to Buyer as the Oil passes the
          flange connecting the cargo hose of the Buyer's nominated tank truck
          or vessel and Sellers' truck loading rack.

    iii.  For the Delivered Diesel under Section 6.3.ii., care, custody,
          control, title and risk of loss shall pass to Buyer as the Oil passes
          the flange connecting Buyer's pipeline at the Waiau Power Plant to the
          Oahu P/L.

    iv.   For the Delivered Diesel under Section 6.5, care, custody, control,
          title and risk of loss shall pass to Buyer as the Oil passes the
          flange connecting the cargo hose of the Seller's nominated barge or
          vessel and the Buyer's designated pipeline.

    v.    For the delivered Jet under section 6.4, care, custody, control, title
          and risk of loss shall pass to Buyer as the jet passes the flange
          connecting the cargo hose of the Seller's tank truck and Buyer's truck
          unloading rack at HELCO's and MECO's respective power plant.

    Section 6.7  Buyer agrees to provide Seller with five (5) days advance
written notice of Oil to be Delivered under Section 6.1, 6.3.ii. or 6.4, and
telephone notification for  Diesel to be Delivered under Section 6.2 or 6.3.i.
Seller shall make all reasonable effort to comply with this notice and advise
Buyer promptly if the delivery time cannot be met.

                                                                         Page 16

                                  ARTICLE VII
                           DETERMINATION OF QUALITY

    Section 7.1  The quality of the Oil purchased by HECO and the quality of Jet
purchased by HELCO and MECO shall be determined on the basis of composite
samples drawn by Seller in such a manner as to be representative of each
Delivery.  The quality of the Oil purchased by MECO or HELCO, i.e., barge
cargos, shall be determined on the basis of composite samples drawn by Seller,
collected at a point prior to entry into each barge, in such a manner as to be
representative of each barge cargo.  The quality of the Oil purchased by MECO-
Molokai shall be determined on the basis of composite samples drawn by Seller
from receiving tanks at the Kaunakakai Terminal after each delivery.  The heat
content of the Oil shall be determined on a monthly weighted average basis for
each Buyer from the same composite samples drawn by Seller at the time and place
described above.  See Addendum 2 hereto for an overview on all sampling.  Such
samples shall be divided into three (3) parts and dated.

    1.  One part shall be used by Seller to determine the heat content (gross
        BTU) per physical gallon and, if needed, the other qualities of Article
        IV ("Seller's Delivered Sample").

    2. One part shall be provided to Buyer for the purpose of verifying Seller's
       determinations ("Buyer's Delivered Sample").

    3. One sealed part shall be provided to Buyer ("Buyer's Delivered Retain").

    Section 7.2  Within sixty (60) days after the end of each month, Buyer shall
give Seller notice of any disagreement with Seller's quality or heat content
determination for Delivered Oil and Delivered Jet during such month.  In the
event that such disagreement is not resolved within thirty (30) days, Buyer's
Delivered Retain shall be submitted to a mutually agreed upon independent
laboratory for inspection, whose determination shall be final and binding on
both parties.  Seller and Buyer shall share equally the cost of such independent
inspections.

                                                                         Page 17
<PAGE>
 
    Section 7.3  If Buyer and Seller agree or the independent inspector
determines that the quality of Delivered Oil and Delivered Jet did not equal the
qualities described in Article IV (regardless if such Oil and Jet passed tests
of conditional acceptance), the Buyer and Seller shall attempt to minimize the
impact.  This may include specification waiver especially if use of Oil and Jet
will not harm Buyer or Seller, or delivering higher quality Oil and Jet in a
timely manner to produce a specification quality blend in Seller's terminal.  If
all such, or similar efforts fail to resolve the quality problem, then Seller at
Seller's expense, shall exchange the non-specification Oil and Jet and other oil
downgraded by commingling with Seller's Oil and Jet, with Oil and Jet meeting
the qualities of Article IV.  However, in no event shall Seller be liable for
any indirect, consequential, special or incidental damages of any kind whether
based in contract, tort (including without limitation negligence or strict
liability), warranty or otherwise allegedly caused by or based upon the
qualities of the Oil and Jet.

                                 ARTICLE VIII
                            MEASUREMENT OF QUANTITY

    Section 8.1  Quantities of the Oil sold and purchased under this Contract at
the HMT shall be determined at the time of each Delivery by gauging the HMT
tanks before and after pumping. Diesel sold and purchased under this Contract
from the Oahu P/L shall be determined at the time of each Delivery by gauging
Seller's tanks at its Barbers Point Refinery before and after pumping. Diesel
sold and purchased under this Contract at the Kaunakakai Terminal shall be
determined at the time of each Delivery by gauging Buyers' tanks at Kaunakakai
before and after pumping. Volumes Delivered hereunder shall be converted to
60(degrees)F, using the latest revision of Table 6 of ASTM IP Petroleum
Measurement Tables, American Edition, ASTM Designation D-1250. Measurements
shall be taken by Seller and witnessed by Buyer or Buyer's agent. However, at
Buyer's option, such measurements shall be taken by a mutually agreed upon
independent inspector. Seller and Buyer shall share equally the

                                                                         Page 18
<PAGE>
 
 cost of independent inspections.  Seller reserves the right to install meters
on the Oahu P/L and to determine quantity as in Section 8.2.

    Section 8.2  Diesel sold and purchased under this Contract at the HDT and
Jet sold and purchased by HELCO and MECO shall be determined at the time of each
Delivery by reading calibrated meters, corrected in each instance to volume at
60(degrees)F in accordance with the latest issue of Table 6 of ASTM IP Petroleum
Measurement Tables, American Edition, ASTM Designation D-1250.  The meters used
at the HDT and Seller's terminals on Hawaii and Maui shall be Seller's meters.
Both Buyer and Seller shall have the right to review each other's routine
certification documents.

    Section 8.3  If Buyer or Seller has reason to believe that the quantity of
Oil and Jet stated for a particular Delivery per Sections 8.1 or 8.2 is
incorrect, the party shall within sixty (60) days of the Delivery date, present
the other party with documentation supporting such determination and the parties
will confer, in good faith, on the causes for the discrepancy and shall proceed
to correct such causes and adjust the quantity, if justified, for the deliveries
in question.

                                  ARTICLE IX

                                  ARTICLE XI
                    SELLER'S FACILITIES ON MAUI AND HAWAII

As used in this Article XI, "Buyer" will refer only to MECO or HELCO.
    Section 11.1

    i.   Seller agrees to provide MECO the use of its storage and handling
         facilities for Diesel Received at Kahului, Maui, and to provide HELCO
         the use of its storage and handling facilities for Diesel and CIFO
         Received at Hilo, Hawaii; for the Delivered Oil under Article VI and
         the third party oil purchased as a result of the force majeure
         conditions of Article XIII, on the terms and conditions described in
         this Article XI. To provide operating flexibility to a valued, long-
         term customer, Seller shall grant HELCO the non-exclusive right to
         terminal oil purchased from third parties at Seller's facility at Hilo,
         Hawaii up to a maximum quantity per calendar year of ------ of diesel
         and ------of fuel oil, which meet the specifications set out herein.
         Buyer agrees to schedule its deliveries such that they contain a
         minimum of ------ of oil such that they arrive at regular intervals.
         For the same reasons, Seller shall grant MECO the non-exclusive right
         to terminal No. 2 diesel fuel purchased from third parties at Seller's
         facility on Maui up to a maximum quantity of ------ per calendar year,
         which meets the specifications set out herein. Buyer agrees to schedule
         its deliveries such that they contain a ------ of diesel fuel and that
         they arrive at regular intervals.

    ii.  Whenever Buyer purchases third party oil which is to be terminaled in
         Seller's facilities, Buyer shall obtain a sample representative of the
         oil in the barge cargo tanks, after the third party supplier has
         completed the loading of such oil into Buyer's nominated barge. See
         Addendum 2 hereto for an overview on all sampling. This sample shall be
         divided into three parts and dated. One part shall be labeled
         "Supplier's loaded sample" and delivered to Seller's representative as
         soon as possible. One part shall be labeled "Buyer's loaded sample."
         One part shall be sealed and labeled "Buyer's loaded retain." These
         samples shall indicate the quality of this mixture of purchased oil and
         the previous

                                                                         Page 22
<PAGE>
 
         cargo remains.  To provide an early warning of any quality problems
with the Received oil, Buyer agrees to perform a preliminary analysis on the
Buyer's loaded sample consisting of API gravity, appearance and, in the case of
diesel fuel, flash point, at the time such third party oil is loaded for
transport.  Buyer also agrees to deliver one copy of such preliminary analysis
promptly to Seller's representative at the Honolulu Marine Terminal and to carry
a second copy on board Buyer's nominated barge for delivery to Seller's
representative upon arrival at the appropriate outer island terminal.  Buyer
further agrees that the cost of any additives which may be required to eliminate
compatibility problems between third party oil and Seller's Oil at the outer
island terminal shall be solely for Buyer's account.

    Section 11.2   Buyer shall provide Seller with estimated arrival times of
the barge transporting the oil for which Buyer desires to use Seller's
facilities on Maui or Hawaii.  Buyer or Buyer's agent shall provide radio or
phone notification to Seller's representative at each unloading location at
least seven days prior to a third-party supplied oil delivery and at least 24
hours prior to a Seller supplied oil delivery.  Buyer or Buyer's agent shall
also provide the Captain of the Port with radio or phone notification at least
24 hours prior to any delivery.  Should the estimated time of arrival change by
two or more hours following the 24 hour arrival report, Buyer or Buyer's agent
shall promptly report the change to Seller's representative and the Captain of
the Port at the place of planned arrival.

    Section 11.3
    i.  Seller shall analyze Seller's Loaded sample of Section 6.1.iv and
        Buyer's supplied results from any Buyer's loaded sample of Section
        11.1.ii for conditional acceptance for receiving the oil, and if
        warranted, analyze Seller's Loaded sample of Section 6.1.iv and
        Supplier's loaded sample of Section 11.1.ii for all the qualities
        described in Article IV, while Buyer's nominated barge is enroute to
        Maui or Hawaii, to reduce the risk of contaminating Seller's terminal
        inventories. See Addendum 2 hereto for an overview of

                                                                         Page 23

        all sampling. If the loaded sample fails conditional acceptance, Seller
        shall promptly notify Buyer of any quality problems with the loaded oil.
        Both Buyer and Seller shall attempt to minimize the impact of any
        quality problem by specifications waiver especially if use of the loaded
        oil will not harm either Buyer or Seller, or by Buyer or Seller
        delivering higher quality oil in a timely manner to produce a
        specification quality blend at Seller's terminal. If all such, and
        similar, efforts fail to resolve the quality problem, then Buyer's
        loaded oil shall not be unloaded into Seller's terminal tanks.
        Buyer may return nonspecification Loaded Oil to Seller's Barbers Point
        refinery, in which case Seller shall replace the non-specification
        Loaded Oil by delivering an equal volume of Oil into Buyer's nominated
        barge at the HMT, in a timely manner.
    ii. All costs and expenses, including transportation, re-refining and
        handling costs incurred in returning and replacing non-specification
        loaded oil and Loaded Oil shall be paid by the party responsible for the
        contamination. Responsibility shall be determined by analyzing the
        Delivered Oil samples of Section 7.1 and the loaded oil samples of
        Section 6.1.iii and Section 11.1.ii. If Buyer and Seller cannot agree
        whether the Delivered Oil or the loaded oil meet the qualities specified
        in Article IV, then the sealed retain of the oil in question, Buyer's
        Delivered retain, Buyer's Loaded retain or Buyer's loaded retain shall
        be submitted to a mutually agreed upon independent laboratory, whose
        determination shall be final and binding on both parties. Seller shall
        have the responsibility for Buyer's transportation and handling costs
        for its own re-refining cost if it is determined that the qualities
        described in Article IV are not met by the Delivered Oil. Otherwise,
        Buyer shall be responsible for Seller's handling and re-refining cost
        and its own transportation and handling costs. The responsible party
        shall reimburse the other party for such costs and expenses within sixty
        (60) days of the delivery date of the non-specification loaded oil.
        However, in no event shall such party be responsible for any indirect,
        consequential, special or incidental damages of any kind whether based
        in contract, tort (including without limitation negligence or strict
        liability), warranty or otherwise

                                                                         Page 24

        allegedly caused by or based upon the quality of the non-specification
        loaded oil. Seller and Buyer shall share equally the cost of any
        independent inspections.

    Section 11.4   Buyer shall be responsible for meeting all Coast Guard dock
watch requirements at Hilo, Hawaii and Kahului, Maui.  Charges levied by any
governmental agency for the use of their facilities at Hilo, Hawaii or Kahului,
Maui, including but not limited to the State of Hawaii's wharf and pipeline
fees, shall be for Buyer's account.

    Section 11.5   Seller will take care, custody and control of Received oil
having conditionally acceptable quality per Section 11.6 at the flange
connecting Seller's independently owned pipeline at each location to the
multiparty diesel pipeline at Kahului Harbor, Maui and the multiparty diesel and
fuel oil pipelines at Hilo Harbor, Hawaii.  Title and risk of loss shall remain
with Buyer.  Seller shall not be responsible for any type of loss of the oil
while it is in Seller's custody except when loss or damage is caused by Seller's
failure to use reasonable care in receiving, handling, storing, or delivering
such oil. Received oil will be commingled with Seller's Oil in Seller's tankage
at Seller's Kahului, Maui or Hilo, Hawaii terminals.

    Section 11.6

    i.    Quality of Received oil at the unloading location shall be determined
          by testing representative samples taken from Carrier's barge tanks.
          See Addendum 2 hereto for an overview of all sampling. Seller, or a
          mutually agreed third party, shall perform the sampling and testing as
          prescribed in the latest API-ASTM laboratory testing standards.
          Samples will be divided into four parts and dated. One part shall be
          tested promptly per Section 11.6.ii. One part shall be labeled
          "Seller's Received Sample," one part shall be sealed and labeled
          "Seller's Received Retain" and one part shall be labeled "Buyer's
          Received Sample" and provided to Buyer.

    ii.   To facilitate Buyer's barge turnaround, one part of the sample taken
          in Section 11.6.i will be promptly tested for its API gravity,
          appearance and in the case of Diesel also for its

                                                                         Page 25
<PAGE>
 
          flash point. Received Oil will be considered conditionally acceptable
          if its API gravity is within 0.3 degrees of its gravity delivered to
          Buyer under Article VI. Received oil will be considered acceptable if
          its API gravity is within 0.3 degrees of the Supplier's loaded sample
          gravity as determined in Section 11.1.ii, and for diesel cargos, if
          its Flash point is above its 150 (degrees)F specification of Section
          4.2.

    iii.  Notwithstanding the above conditional acceptance, Seller may use
          Seller's Received Sample to determine all the qualities described in
          Article IV for Received oil. Within thirty (30) days after each oil
          cargo unloading, Seller shall give Buyer notice of any claim of
          contamination of Seller's Oil from commingling with Received oil. In
          the event that such claim is not resolved within thirty (30) days of
          the original claim, Seller's Received Retain shall be submitted to a
          mutually agreed upon independent laboratory for inspection, whose
          determination shall be final and binding on both parties. Seller and
          Buyer shall share equally the cost of such independent inspections.

    iv.   If Buyer and Seller agree or the independent inspector determines that
          the quality of the Received oil did not meet the qualities described
          in Article IV, and the most recent Delivered Oil did meet the quality
          described in Article IV, both Buyer and Seller shall attempt to
          minimize the impact of any quality problem on Buyer by waiver of
          Buyer's requirement to meet specifications especially if Seller's use
          of the oil will not significantly harm Seller, or by Buyer or Seller
          delivering higher quality oil in a timely manner to produce a
          specification quality blend at Seller's terminal. If all such, and
          similar, efforts fail to resolve the quality problem, then Buyer will
          reimburse Seller the transportation, handling and re-refining costs of
          exchanging Buyer's and Seller's oil, with oil meeting the qualities
          described in Article IV. Such reimbursement shall occur within 60 days
          of Seller's original claim. However, in no event shall Buyer be liable
          for any indirect, consequential, special or incidental damages of any
          kind whether based in contract, tort (including without limitation
          negligence or strict liability), warranty or otherwise allegedly
          caused by or based upon the quality of the Received oil.

                                                                         Page 26

    Section 11.7   The quantity of Received oil and Received Oil over which
Seller takes custody shall be determined at the time of each barge cargo
unloading by gauging Seller's terminal tank before and after pumping. Free water
shall be drawn off prior to each level measurement. Volumes delivered hereunder
shall be converted to 60(degrees)F, using the latest revision of Table 6 of ASTM
IP Petroleum Measurement Tables, American Edition, ASTM Designation D-1250.
Measurements shall be taken by Seller and witnessed by Buyer or Buyer's agent.
However, at Buyer's option, such measurement shall be taken by a mutually agreed
upon independent inspector. Buyer and Seller shall share equally the cost of
independent inspections.

    Section 11.8   In the event that Buyer and Seller have agreed to commingle
their oil in a barge or vessel compartment to reduce freight costs, and there
are discrepancies between either the quantities of oil loaded per Section 6.1
and unloaded per Section 11.7 or the qualities of oil loaded per Section 7.1 and
unloaded per Section 11.6, then Buyer and Seller shall share the benefits or
losses of the discrepancy proportionally to the loaded volumes.

    Section 11.9   Buyer will provide Seller's terminal representative, during
normal working hours, at least 24-hour notice of any transfers required from
Seller's facilities in Kahului or Hilo.

    Section 11.10  Buyer shall regain care, custody and control of Returned Fuel
Oil at the flange connecting Seller's Hilo terminal pipeline to Buyer's
pipeline.

    i.     The quantity of Fuel Oil over which Seller returns custody shall be
           determined at the time of each transfer by gauging Seller's terminal
           tanks before and after pumping. Volumes Returned hereunder shall be
           converted to 60(degrees)F, using the latest revision of Table 6 of
           ASTM IP Petroleum Measurement Tables, American Edition, ASTM
           Designation D-1250. Measurements shall be taken by Seller and
           witnessed by Buyer or Buyer's agent. However, at Buyer option, such
           measurements shall be taken by a mutually agreed upon

                                                                         Page 27

           independent inspector. Buyer and Seller shall share equally the cost
           of independent inspections.

    ii.    Buyer and Seller agree that Buyer shall maintain a positive inventory
           of Fuel Oil at Seller's Hilo terminal for Buyer's use, but
           acknowledge that a small negative inventory may occasionally result
           after Fuel Oil custody transfers from Seller to Buyer. Seller shall
           maintain a record of Buyer's net Fuel Oil inventory stored in its
           Hilo terminal based on receipts as determined in Section 11.7 and
           returns as determined in Section 11.10.i. Seller will provide book
           inventory records once each week, convenient to Seller's normal
           weekly inventory period. If at the end of any annual period, the net
           Fuel Oil inventory is negative, Seller will invoice Buyer and Buyer
           will pay Seller an amount equal to the net negative inventory in
           barrels multiplied by the sum of the December CIFO sales price at the
           end of the annual period per Section 5.1 and the December commercial
           freight rate charged by HELCO's carrier for a minimum cargo size of
           38,000 barrels to Seller at the end of the annual period for CIFO
           transport between Honolulu Harbor, Oahu and Hilo Harbor, Hawaii.

         Section 11.11  Buyer shall regain care, custody and control of Returned
diesel at the end of the fill pipe connecting Seller's terminal pipelines to
Carrier's tank trucks.  Transfers will be made in minimum 5,000 gallons per
delivery load.

    i.    The quantity of diesel over which Seller returns custody shall be
          determined at the time of each transfer by reading Seller's calibrated
          meters corrected in each instance to volume at 60(degrees)F using the
          latest revision of Table 6 of ASTM IP Petroleum Measurement Tables,
          American Edition, ASTM Designation D-1250. If Buyer or Seller have
          reason to believe that the quantity of Returned diesel stated for a
          particular transfer is incorrect, that party shall within fifteen days
          of the transfer date, present the other party with documentation
          supporting such determination and the parties will confer, in good
          faith, on the causes for the discrepancy and shall proceed to correct
          such causes and adjust the quantity, if justified, for the transfers
          in question.

                                                                         Page 28
<PAGE>
 
    ii.   Seller shall maintain records of Buyer's net diesel inventories stored
          at each of its Kahului, Maui and Hilo, Hawaii terminals, based on
          receipts as determined in Section 11.7 and returns as determined in
          Section 11.11.i. Seller will provide book inventory records once each
          week, convenient to Seller's normal weekly inventory period.

    iii.  Seller will periodically reconcile meter measurements with tank
          gaugings. Buyer may review Seller's reconciliation calculations.
          However, there will be no retroactive adjustments to the volumes
          delivered or received as a result of this procedure.

    Section 11.12  Seller shall be under no obligation to provide Buyer
quantities of Returned oil greater than Buyer's current net oil inventory.
However, Seller will attempt to meet Buyer's unanticipated needs, after
considering the needs of its other customers and its own available inventory.

    Section 11.13

    i.    Returned oil transferred by Seller shall meet the qualities described
          in Article IV. Seller shall verify the quality of the Returned oil by
          taking a representative sample of the oil in Seller's tanks on Maui
          and Hawaii after each receipt of Buyer's or Seller's oil. See Addendum
          2 hereto for an overview of all sampling. This sample shall be
          promptly tested by Seller for its API gravity, appearance and in the
          case of diesel also for its flash point. Buyer and Seller agree that
          successful passage of the prompt test on this sample is sufficient
          evidence for Seller to return oil to Buyer, without limiting Buyer's
          rights within Section 11.13.ii. Seller shall also take samples
          representative of the Returned oil after each receipt of Buyer's or
          Seller's oil into Seller's terminal. These samples will be divided
          into three parts and dated. One part shall be labeled "Seller's
          Returned Sample." One part shall be sealed and labeled "Buyer's
          Returned Retain" and one part shall be labeled "Buyer's Returned
          Sample." Both shall be provided to Buyer.

    ii.   Notwithstanding the above conditional acceptance, Buyer may use
          Buyer's Returned Sample to determine all the qualities described in
          Article IV for the Returned oil. Within

                                                                         Page 29
<PAGE>
 
          thirty (30) days after each oil delivery, Buyer shall give Seller
          notice of any claim of contamination and of resulting losses. In the
          event that such claim is not resolved within thirty (30) days of the
          original claim, Buyer's Returned Retain shall be submitted to a
          mutually agreed upon independent laboratory for inspection, whose
          determination shall be final and binding on both parties. Seller and
          Buyer share equally the cost of such independent inspections.

    iii.  If Buyer and Seller agree or the independent inspector determines that
          the quality of the Returned oil did not meet the qualities described
          in Article IV and that the most recent Received Oil and Received oil
          did meet the qualities described in Article IV, both Buyer and Seller
          shall attempt to minimize the impact of any quality problem on Seller
          by waiver of Seller's requirement to meet specifications, especially
          if Buyer's use of the oil will not significantly harm Buyer, or by
          Seller returning higher quality oil to produce a specification quality
          blend at Buyer's plants. If all such, and similar, efforts fail to
          resolve the quality problem, then Seller will, at Seller's expense,
          exchange Buyer's Returned oil and, if appropriate, any of Buyer's
          other similar oil which has been downgraded by commingling with the
          Returned oil, with oil meeting the qualities described in Article IV.
          Seller shall make its best, reasonable effort to replace Buyer's oil
          in a timely manner. However, in no event shall Seller be liable for
          any indirect, consequential, special or incidental damages of any kind
          whether based in contract, tort (including without limitation
          negligence or strict liability), warranty or otherwise allegedly
          caused by or based upon the quality of the Returned oil.

         Section 11.14 Seller will invoice Buyer and Buyer will pay Seller per 
         -------------
Article IX, terminating and handling fees based on the quantities of oil 
determined in Section 11.7 at the rates listed below.

      i. At Kahului, Maui, the terminating and handling fee shall be 
- --------------    


                                                                        Page 30
<PAGE>
 
    ii.  At Hilo, Hawaii, the terminaling and handling fee shall be ---------
 

    For the purpose of invoicing, the terminaling and handling services shall be
    considered received by Buyer when Seller first takes custody of Buyer's oil
    per Section 11.5.


                                  ARTICLE XII
                                 CONTINGENCIES

    Section 12.1   As used in this Article XII, the term "contingency" means:
    (a) any event reasonably beyond the control of the party affected;

    (b) compliance, voluntary or involuntary, with a direction or request of any
government or person purporting to act with governmental authority; excluding,
however, any such direction or request restricting or otherwise regulating
combustion of the oil to be purchased by Buyer hereunder, the effect of which
restrictions or regulation upon the parties' performance shall be governed by
Section 12.5 of this Contract;

    (c) total or partial expropriation, nationalization, confiscation,
requisitioning or abrogation or breach of a government contract or concession;

    (d) closing of, or restriction on the use of, a port or pipeline;

    (e) maritime peril (including but not limited to, negligence in navigation
or management of vessel, collision, stranding, destruction, or loss of vessel),
storm, earthquake, flood;

    (f)  accident, fire, explosion;

    (g) hostilities or war (declared or undeclared), embargo, blockage, riot,
civil unrest, sabotage, revolution, insurrection;

    (h) strike or other labor difficulty (whomever's employees are involved),
even though the strike or other labor difficulty could be settled by acceding to
the demands of a labor group; or,

    (i) loss or shortage of supply, production, manufacturing, distribution,
refining, transportation, delivery facilities, receiving facilities, equipment,
labor, material, power

                                                                         Page 31

generation or power distribution caused by circumstances which the affected
party is not able to overcome by the exercise of reasonable diligence or which
the affected party is able to overcome only at substantial additional expense in
relation to the expected revenue, benefits or rights related directly to this
Contract.

    Section 12.2   Seller shall not be obligated to sell or deliver Oil or Jet
to the extent that performance of this Contract is prevented, restricted or
delayed by a contingency which significantly affects Seller's ability to supply,
manufacture or transport Oil or Jet to Buyer under this Contract from Seller's
U.S. West Coast and Hawaiian refineries.  In such circumstances, Deliveries of
Oil or Jet to Buyer may be reduced on a basis as equitable to Buyer as to
Seller's and its affiliates' other customers of crude and petroleum products,
and Seller shall not be obligated to acquire additional crude, oil or jet but to
the extent that it does acquire additional crude, oil or jet, Buyer shall be
entitled to an equitable share of the oil or jet acquired or derived from the
crude acquired, at a price to be agreed from time to time.

    Section 12.3   Buyer shall not be obligated to purchase, receive or use Oil
or Jet to the extent that performance of this Contract in the customary manner
is prevented, restricted or delayed by a contingency.  In such circumstances,
purchases from Seller may be reduced on any basis as equitable to Seller as to
Buyer's other suppliers of oil or jet.

    Section 12.4   If at any time any price determined under this Contract
cannot be given effect because to do so would violate a direction or request of
any government or person purporting to act with governmental authority, Buyer
and Seller shall attempt to agree on an alternate course of action but failing
agreement within 10 days the party adversely affected may suspend performance
with respect to the quantity of Oil or Jet affected by the direction or request.

                                                                         Page 32
<PAGE>
 
    Section 12.5   To the extent that any governmental regulation requires
combustion of oil or jet meeting specifications other than those in Article IV,
Buyer and Seller shall negotiate in good faith to agree on an alternative course
of action that will allow Buyer to comply with such regulation while purchasing
the equivalent of the full quantity of oil or jet it would be required to
purchase under Article III, at a price and on other terms and conditions that
are fair to both parties. Seller shall have no obligation to deliver oil or jet
meeting new specifications if it is not available for purchase from third
parties and Seller cannot manufacture such oil or jet in existing facilities
without new capital investment.

 If Buyer and Seller do not agree on such an alternative course of action, then
Buyer may comply with such regulation in any reasonable manner it chooses,
including the option to purchase from other sources for its plant located within
the area in which such regulation specifically applies, fuels which will enable
Buyer to comply with such regulation. In such case, Buyer's minimum purchase
requirement under Article III shall be reduced accordingly.

    Section 12.6   Seller's obligations under this Contract shall be contingent
on Seller's continued ownership or operation of its refining or delivery
facilities in Hawaii or the U.S. West Coast.  Seller shall have the right to
terminate this Contract in the event the ownership and operation of its refining
and delivery facilities in Hawaii and the U.S. West Coast are transferred to an
entity other than an affiliate.  Seller shall give Buyer 180 days' written
notice.

                                 ARTICLE XIII
                       EFFECT OF SUSPENSION OR REDUCTION

    Section 13.1   In the event of any suspension of sales and Deliveries under
Article XII, Seller shall not be obligated to sell and Buyer shall not be
obligated to buy, after the period of suspension or reduction, the undelivered
quantity of Oil or Jet which normally would have been sold and delivered
hereunder during the period of suspension or reduction.

                                    Page 33
<PAGE>
 
    Section 13.2   If sales and Deliveries are suspended under Article XII for
more than 180 days, Seller or Buyer shall then have the option while such
suspension continues to terminate its obligations to the other party under this
Contract on 30 days' written notice to the other party.

    Section 13.3   Any party which relies upon Article XII shall give the other
party prompt notice thereof specifying the anticipated amount and duration of
any suspension or reduction of Deliveries. It shall also give prompt notice when
it no longer expects to rely on Article XII and Deliveries shall be reinstated
subject to all conditions of this Contract, unless this Contract has been
terminated previously under Section 13.2.

    Section 13.4   Nothing in Article XII shall relieve Buyer of the obligations
to pay in full in United States currency for the Oil or Jet sold and Delivered
hereunder and for other amounts due to Buyer to Seller under this Contract, nor
relieve Seller of the obligation to return to Buyer the net positive inventory
of Buyer's oil stored in Seller's Hilo, Hawaii and Kahului, Maui terminals.

    Section 13.5   While Deliveries are suspended or reduced by Seller pursuant
to Article XII, it shall not be a breach of this Contract for Buyer to buy from
a supplier other than Seller the quantities of Oil or Jet which Seller does not
Deliver. During this period of time, there will be no minimum volume
requirements. After any suspension or reduction has ended, minimum and maximum
volume requirements for the semiannual period in which the suspension or
reduction occurred will be reduced in proportion to the ratio of the number of
days within the semiannual period during which no suspension or reduction was in
effect, to the number of days within the semiannual period.

                                                                         Page 34

    Section 14.1   Waiver by one party of the other's breach of any provision of
this Contract shall not be deemed a waiver of any subsequent or continuing
breach of such provisions or of the breach of any other provision or provisions
hereof.

    Section 14.2   This Contract shall not be assignable by either party without
the written consent of the other, which shall not be unreasonably withheld,

this Contract at any time and, except for Buyer's obligation to pay in full in
United States currency for the Oil sold and Delivered hereunder and for other
amounts due by Buyer to Seller under this Contract, and for Seller's obligation
to return to Buyer the net positive inventory of Buyer's oil stored in Seller's

any other right or remedy of such party in respect of such breach, terminate its
obligations under this Contract, except for Buyer's obligation to pay in full in
United States currency for the Oil or Jet sold and delivered hereunder and for
other amounts due by Buyer to Seller under this Contract, and for Seller's
obligation to return to Buyer the net positive inventory of Buyer's oil stored

election of one remedy shall not exclude another.

 Except as provided under Sections 18.2 and 18.4, in no event shall either party
be liable for any indirect, consequential, special or incidental damages of any
kind whether based in contract, tort (including without limitation negligence or
strict liability), warranty or otherwise.

 Seller's termination of its obligations to a Buyer in this Contract due to
default by that Buyer shall not terminate Seller's obligations to the remaining
Buyers not in default of this Contract.

or master on the tug, to undertake such measures as are reasonably necessary to
prevent or mitigate the pollution damage.  Seller or its agent shall keep Buyer
advised of the nature and results of any such measures taken and, if time
permits, intended to be taken.  Any of the aforementioned measures shall be at
Buyer's sole expense (except to the extent that such escape or discharge was
caused by the negligence or willful action of Seller or its agent), provided
that if Buyer considers said measures should be discontinued, Buyer shall so
notify Seller or its agent and thereafter Seller or its agent shall have no
right to continue said measures at Buyer's authority or expense except as
provided in Section 18.4.  This provision shall be applicable only between Buyer
and Seller and shall not affect, as between Buyer and Seller, any liability of
Buyer to any third parties, including but not limited to governments.

cooperate with all efforts and to pay all reasonable costs associated with

     4.3  Reallocation of Deliveries.  If during any 15 calendar day period,
deliveries of LSFO by SELLER to Kalaeloa Partners, L.P. ("Kalaeloa") are less
than 20,000 barrels due to an unanticipated equipment outage at the oil-fired
combined cycle facility owned by Kalaeloa at Campbell Industrial Park, SELLER
and BUYER shall agree to reallocate deliveries of LSFO by SELLER, to the extent
required by BUYER and not required by Kalaeloa, to BUYER.  The reallocated LSFO
shall be priced on the same basis as optional purchases as provided for in
Section 4.2.

                                   ARTICLE V
                                     PRICE


     The Product Price in U.S. Dollars ("USD") per barrel shall be determined 
monthly based on the following price formula:

     --------------------------------

     Where:

     P   =   Product Price in U.S. Dollar per barrel for the calendar month of 
             delivery.

     S1  =   Base price which shall consist of Platt's assessed value of
             Singapore Cargoes 0.3% sulfur LSWR Mixed/Cracked. The price per
             barrel shall be the simple average of Friday's high and low prices
             for all dates of publication of Platt's during the period beginning
             the 21st of the second month immediately preceding the nominated
             month of delivery and ending the 20th of the month immediately
             preceding the nominated month of

                                      5  
<PAGE>

         delivery. If Platt's does not publish a high and low prices for a
         particular Friday during the relevant period, the high and low prices
         for the closest preceding day for which a Platt's Oilgram Price report
         is published will be used.

S2   =   The simple average of the high and low prices for Los Angeles Bunker C
         fuel as reported by the Platt's Bunkerwire for all dates of publication
         during the period beginning the 21st day of the second month
         immediately preceding the nominated month of delivery and ending the
         20th day of the month immediately preceding the nominated month of
         delivery, expressed in USD per barrel using a conversion factor of
         6.368 barrels per metric ton.

F1   =   A factor for quality differential of Product delivered such as sulfur 
         content

where F1 = 0.10 x (S2 - S1).

F2   =   The actual gross hear content of each Product Delivery pursuant to
         Section 6.3 and Exhibit A, expressed in million BTUs per barrel with
         three significant figures to the right of the decimal point.

F3   =   A factor for tanker freight defined as follows:

F3   =   F5 + FRD1 + FRD2

         Where F3 is a market index for freight, defined for each calendar 
         quarter as the sum of:

F5   =   The simple average of the Average Freight Rate Assessment ("AFRA")
         Worldscale Points for the average of Large Range 1 vessels, as
         published monthly by London Tanker Brokers Panel Limited for the three
         monthly publications in the calendar quarter immediately preceding the
         calendar quarter of the nominated month of delivery, multiplied by the
         Worldscale 100 rate for voyages between Singapore and Barbers Point,
         Hawaii, applicable to the year of the quarter of the applicable AFRA
         data, expressed in New Worldscale rates, as published by Worldscale
         Associates (London Limited) in its New Worldscale Nominal Freight Scale
         (Worldscale). Monthly AFRA publications show rates of vessel voyages
         which occurred during the period beginning the 16th day of the second
         month immediately preceding that publication and ending the 15th day of

                                       6
<PAGE>
 
         the month immediately preceding the publication. Exhibit B includes an 
         illustrative computation; plus,

FRD1  =  A fixed rate differential, if and as provided by Worldscale, with
         respect to the Additional Insurance Premium for Basic ($500 Million)
         coverage of Oil Pollution Liability Insurance on vessels carrying
         persistent oils to and from the U.S.A., consistent with a typical
         vessel derived in Exhibit C attached to this Contract, plus.

FRD2  =  A fixed rate differential, if and as provided by Worldscale, with
         respect to the Additional Insurance Premium for Excess ($200 Million)
         coverage of Oil Pollution Liability Insurance on vessels carrying
         persistent oils to and from the U.S.A., consistent with a typical
         vessel derived in Exhibit C attached to this Contract.

    This market index for freight will be expressed in USD per barrel, using a 
conversion factor of 6.75 barrels per metric ton.

T    =   The Hawaii General Excise Tax, the Hawaii Environmental Response Tax,
         the Federal Superfund Petroleum Fee, the Federal Oil Spill Liability
         Trust Fund Fee, if and when applicable, and any other tax imposed on
         the sale of Product.

    A sample calculation of the formula for determining the Product Price is
included in Exhibit B, part I.

    Platt's Oilgram Price Report and Platt's Bunkerwire shall include any 
successor publication(s) and, in the event of discontinuance of these 
publications, or the publications referred to in the freight adjustment Exhibit

    The price for Product delivered shall be based on the price for the month of
delivery originally nominated by the BUYER, regardless of the month in which the
quantity of Product nominated is actually delivered. A Delivery is defined as
beginning with the initiation of pumping from SELLER's refinery tank, nominated
issuing tank or vessel to BUYER's Barbers Point Tank Farm and ending with the
subsequent cessation of continuous pumping of Product in such amount as is
determined by the independent inspector's Certificate of Quantity.

    All prices, price components, price component elements, including their
averages and factors, adjustments thereto and other sums payable hereunder in
this Contract shall be stated in the nearest thousandth of a dollar unless
specifically stated otherwise.

                                   ARTICLE VI
                                    DELIVERY

     6.1  Notification and Product Delivery.  Subject to the minimum and maximum
amounts specified in Section 4.1, BUYER will provide SELLER notice
("Nomination") of the amount to be sold and delivered by SELLER and bought and
received by BUYER for each calendar month no later than seventy-five (75) days
prior to the first day of said month ("Nomination Month").  The Nomination shall
specify both the quantities of Product and the delivery timing for the amount to
be sold for the first and second half of the Nomination Month, respectively.  No
later than 10 days prior to the beginning of each calendar month, SELLER will
provide BUYER a schedule of deliveries to be made for the following two months.
The delivery

                                       8
<PAGE>
 
schedule shall specify the approximate quantity, the approximate date and a
characterization of the approximate viscosity, either low, 100 - 200 SSU at 210
DF, medium,  201 - 350 SSU at 210 DF or high, over 350 SSU at 210 DF of each
separate delivery.  SELLER shall notify BUYER of a change to said delivery
schedule because of one of the following causes with respect to each individual
delivery when it shall become known to SELLER:
 
     a)        A change in volume, if such change is in excess of 10% of the
previously advised delivery volume; or

     b)   A change in date, if such change is greater than 2 days from the
previously advised date; or

     c)   A change in the previously advised viscosity characterization.

     BUYER shall not be required to take Delivery, and SELLER shall not be
required to make Delivery of more than fifty percent of a monthly nomination in
any ten consecutive day period.  The minimum and maximum amounts specified in
Section 4.1 to be delivered in any given month may be further modified upon
mutual agreement of the parties.

     If for reasons other than Force Majeure, BUYER's anticipated demand for
LSFO on an annual basis during any calendar year during the term of this
Contract declines below the BUYER's minimum annual quantity set forth in Section
4.1 (the difference between BUYER's anticipated demand and BUYER's minimum
annual quantity being a "Purchase Deficit Position"), then BUYER shall give
prompt written notice to SELLER.

                                       9
<PAGE>
 
     If for reasons other than Force Majeure, SELLER shall have delivered
Product for the Nomination Month such that the delivery rate, expressed in
barrels per day, is below 85% of the nominated volume as computed on a month-to-
date ratable basis, found by multiplying the day of the Nomination Month by the
nominated rate of delivery for that month ("Failure to Supply Position"), then
SELLER shall give prompt written notice to BUYER.

     6.2  Title and Risk of Loss.  Title to Product and the risk of loss of
Product shall pass to BUYER at the connection between the flange of SELLER's
pipeline and BUYER's tank farm pipeline at Barber's Point.

     6.3  Determination of Quality.  The quality and heat content of the Product
shall be determined on the basis of a composite sample(s) drawn by a mutually
agreed upon independent inspector from SELLER's issuing tank(s) in such a manner
as to be representative of each individual Delivery.  SELLER and BUYER shall
share equally the cost of independent inspections.  If the Delivery of Product
is from more than one issuing tank, the specifications of the total Delivery of
Product shall be determined on a volumetric weighted average from the
representative samples drawn by the independent inspector.  The representative
samples drawn from SELLER's tank(s) shall be divided into a minimum of three (3)
parts:

     1.   One part shall be used by for an analysis by SELLER's laboratory  to
determine quality and heat content (gross Btu) per barrel.

     2.   One part shall be provided to BUYER for the purpose of verifying
SELLER's determinations.

                                       10
<PAGE>
 
     3.   At least one part shall be sealed and provided to BUYER, or to the
independent inspector, to be retained.

     SELLER agrees to provide BUYER a copy of SELLER's laboratory analyses of
the tank final samples, or a preliminary laboratory analyses if the analyses of
the tank final samples is not available, showing sulfur content, flash point and
sediment and water content prior to commencing delivery of the Product,
provided, however, that SELLER shall provide BUYER the complete Certificate of
Quality no later than two working days after the completion of the Delivery.
BUYER shall have the right to perform laboratory analyses in order to verify the
results of SELLER's laboratory analyses.  The official determination of gross
heat content shall be based upon SELLER's laboratory results provided that the
arithmetic difference between SELLER's and BUYER's laboratory results is equal
or less than the then existing reproducibility standard (currently 0.40 MJ/kg)
for ASTM test D-240.  If the difference between SELLER's and BUYER's laboratory
results is greater than this ASTM reproducibility standard, the parties will
confer, in good faith, to resolve the difference.  In the event of an
unresolvable difference between BUYER and SELLER, BUYER's sealed sample will be
provided to an independent laboratory for an official determination, which shall
be binding upon the parties.  SELLER and BUYER shall share equally the costs of
independent tests and determinations.

     The Product received by BUYER in a Delivery may include some amount of
pipeline displacement stock ("Pipeline Fill"). The specification of the Pipeline
Fill shall be determined by the SELLER on the basis of SELLER's representative
sample of the storage tank from the which

                                       11
<PAGE>
 
the Pipeline Fill was issued. SELLER agrees to provide BUYER a copy of a
laboratory analysis of the Pipeline Fill's specifications prior to shipment.

     To provide an early warning of any quality problems with the Product,
SELLER agrees to perform a pre-shipment computer simulation blend ("Blend") of
LSFO from each issuing tank and Pipeline Fill on a volumetric weighted average
basis.  The computer simulation shall provide confirmation of the Blend's API
gravity, viscosity and percent by weight sulfur content. SELLER agrees to inform
BUYER or BUYER's representative of the Blend results prior to shipment.

     SELLER agrees that under no circumstances shall it deliver Product to BUYER
should the percent by weight of sulfur content of the Blend, determined by
computing the weighted average by volume of LSFO issued from the SELLER's
tank(s) and the Pipeline Fill volume, be greater than 0.50%, without BUYER's
express written permission.

     If SELLER or BUYER has reason to believe that the quality or quantity of
Product stated for a specific Delivery per Section 6.3 or Section 6.4 is
incorrect, that party shall within thirty (30) days after the later of the date
of the complete Certificate of Quality or the date of the final determination of
gross heat content, present the other party with documents supporting such
determination and the parties will confer, in good faith, on the causes for the
discrepancy and shall proceed to correct such causes and adjust the quality and
quantity, if justified, for the Delivery in question.  In the event of an
unresolvable difference between SELLER and BUYER, the sealed part of the
representative sample in the possession of BUYER or the independent

                                       12
<PAGE>
 
inspector shall be provided to an independent laboratory for an official
determination, which shall be final.  SELLER and BUYER shall share equally the
cost for such independent laboratory determination.

     If the quality of the Product received by BUYER fails to conform to the
requirements of Article III of this Contract, both BUYER and SELLER shall
attempt to minimize the impact of any quality problem by specification waiver if
the use of the Product will not unreasonably cause harm to BUYER, or by SELLER
delivering higher quality oil in a timely manner to produce a specification
quality blend in BUYER's storage tank(s).  If all such, and similar, efforts
fail to resolve the quality problem, then BUYER may return non-specification
Product to SELLER, in which case SELLER shall replace the non-specification
Product to BUYER in a timely manner.  All reasonable costs and expenses,
including BUYER's handling costs incurred in returning and replacing non-
specification Product, shall be paid by SELLER.

     6.4  Determination of Quantity.  Quantities of the Product delivered
hereunder shall be determined at the time of each Delivery by gauging SELLER's
tank(s) immediately before and after pumping. Volumes delivered hereunder shall
be converted to 60 [degrees] F, using the latest revision of ASTM Table 6B.
Measurements shall be taken jointly by representatives of SELLER and BUYER or by
a mutually agreed upon independent inspector. SELLER and BUYER shall share
equally the cost of independent inspections.

     6.5  Purchase Deficit.  So long as the BUYER is in a Purchase Deficit 
Position as defined in Section 6.1.

                                      13

provided that SELLER can supply the balance of BUYER's Product requirements 
within the month nominated. The Purchase Deficit position shall terminate when 
total cumulative purchases under this Contract exceed the minimum annual 
quantities prorated on a monthly basis. Nothing in this Section 6.5 shall be 
construed as a waiver or limitation of any rights or remedies SELLER may have 
with respect to BUYER's failure to comply with Section 4.1.

     6.6  Failure to Supply.  In the event that the SELLER is in a Failure To
Supply Position, both BUYER and SELLER shall attempt to minimize the impact of
any Failure To Supply Position such that it not impose an unreasonable risk to
BUYER.  If the amount of deficient Product is such that SELLER's Delivery of
Product to BUYER in the Nomination Month at the nominated volume, as computed on
a month-to-date ratable basis, is deficient in aggregate by 50,000 barrels,
BUYER may, at its option, purchase the undelivered Product elsewhere at the then
prevailing market rates.  The BUYER will invoice, and the SELLER shall pay, the
cost difference between purchased Product and cost of Product if it had been
delivered by SELLER.  If the BUYER elects to purchase Product from other sources
under this Section 6.6, the annual purchase requirement referenced in Section
4.1 and Section 6.1 shall be reduced correspondingly.

                                    PAYMENT

     7.1  Method of Payment.  Invoices shall be prepared by SELLER after a
Delivery has been completed.  Invoices shall be accompanied by full
documentation, acceptable to the BUYER, including quality certificates, quantity
documentation, and price calculation.  Payment shall be made without discount in
USD within 7 business days from the receipt of invoice by wire transfer of
immediately available funds to:

                               Citibank, New York

                                Account #4064332

     7.2  Payments.  If SELLER's final laboratory result for gross heat content
is unavailable or if said laboratory result is disputed by BUYER pursuant to
Section 6.3, SELLER may issue a provisional invoice calculated on the basis of
the heat-content standard of 6.2 million BTU per barrel.  BUYER shall make
payment for such provisional invoice in accordance with Section 7.1.  If an
invoice incorporating an item other than a heat rate adjustment which is
disputed has been sent to BUYER, then BUYER shall make payment in accordance
with Section 7.1 for such invoice items or that portion of the invoiced delivery
which is not disputed by BUYER and in which case BUYER shall make such
adjustment to taxes and other value-dependent items as are reasonable under the
circumstances.  The provisional invoice or invoice incorporating items in
dispute shall be adjusted in accordance with the terms of Article V by
subsequent invoicing or by issuing a credit or debit with respect to the
original invoice within 7

                                       15
<PAGE>
 
business days of receipt of the independent laboratory determination pursuant to
Section 6.3 or other resolution of the issue in dispute.  BUYER shall make
payment for such subsequent invoices or debits in accordance with Section 7.1.
BUYER shall have the option to apply such credit against payments to be made
subsequent to the receipt of the credit, or if such payments are not expected to
be made within 7 business days, BUYER shall be able to receive said credit in
immediately available funds within 3 business days of SELLER's receipt of
BUYER's written instructions.
 
     7.3  Interest.  Interest will accrue on all amounts not paid within 7
business days of receipt of provisional or final invoice at the then existing
London Inter-Bank Offered Rate (LIBOR).

                                  ARTICLE IX
                                 RENEGOTIATION

     It is understood and agreed that both parties entered into this Contract in
reliance on governmental laws, rules, decrees, orders, regulations, and
interpretations or implementation thereof in effect on the date of execution of
this Contract or any subsequent amendments hereto, to the extent that they
directly or indirectly affect the Product sold hereunder.  If at any time any of
the said laws, rules, regulations, implementations or interpretations thereof
are changed or if new laws, rules, regulations or new interpretations and
implementations thereof become effective, and such change or new laws, rules,
regulations, interpretations or implementations thereof have a significant
adverse economic effect upon either party, such that performance of this
Contract would be inequitable or cause financial hardship to the affected party,
then the affected party shall have the option to call for renegotiation of the
Product Price or any other provision of this Contract the performance of which
by the affected party would be inequitable or cause financial

                                       17
<PAGE>
 
hardship.  Such option shall be exercised by the affected party at any time
after such a change or new law, rule, regulation, interpretation or
implementation thereof is effective, by giving notice to the other party of the
call to renegotiate.  Within ten (10) calendar days after the date of such
notice, the parties shall enter into negotiations and in the event that the
parties do not agree upon a new Product Price or other provision satisfactory to
both parties within forty (40) calendar days after the date of such notice, the
affected party shall have the right to terminate this Contract effective thirty
(30) days after giving notice of termination to the other party within thirty
(30) days immediately following the forty (40) day negotiation period.  Until a
mutually satisfactory new Product Price or other provision has been agreed upon,
or until this Contract is terminated as provided herein, the Product Price or
other provision that was in effect when the request for renegotiation was made
shall continue in full force and effect.

                                   ARTICLE X
                    TAXES, ASSESSMENTS, LEVIES AND IMPOSTS

     BUYER shall reimburse SELLER for all taxes, assessments, levies and imposts
of whatsoever kind or nature imposed on SELLER by any governmental or quasi-
governmental body (including without limitation the Hawaii Gross Excise Tax)
with respect to the sale of Product under this Contract.  Notwithstanding the
foregoing, BUYER shall not be required to reimburse SELLER for any tax measured
by or based on the net income of SELLER or for real

                                       18
<PAGE>
 
property taxes or to duplicate any item of expense of SELLER which is included
in the Product Price as  provided for in Section 4.2 and  Article V of this
Contract.

                                  ARTICLE XI
                                 FORCE MAJEURE

     11.1  Force Majeure.  As used in this contract, an event or act of "force
majeure" is defined as follows:  acts of God, wars, riots, strikes, labor
disputes, lockouts, blockades, insurrections, inability to secure materials or
labor by reason of allocations promulgated by governmental agencies,
unavailability of shipping of crude oil supplies, epidemics, landslides,
lightning, earthquakes, fires, floods, tidal waves, volcanic eruptions,
explosions, failure of machinery or pipelines, or any other causes not within
the control of the affected party.

     11.2  Obligations Suspended.  BUYER's obligation to purchase or receive
Product, or SELLER's obligation to sell or delivery Product, shall be suspended
to the extent performance is prevented by an event or act of force majeure for
any period in which such event or act exists as to the party claiming force
majeure; and so long as such party is exercising its good faith efforts to
overcome such force majeure event.  However, nothing in this Article excuses
BUYER from its obligation to make payments of money due SELLER for Product
already delivered to BUYER.

     11.3  Notice of Force Majeure.  The party claiming force majeure agrees to
give the other party prompt written notice of an act or event of force majeure.
The party claiming force majeure shall use due diligence to cure any act or
event of force majeure, and shall give the other

                                       19
<PAGE>
 
party prompt notice after the act or event of force majeure has terminated.
This Article shall not require any party to settle or compromise any strike or
labor dispute.

     11.4  No Make-Up Requirement.  After the act or event of force majeure has
terminated, SELLER shall not be obligated to sell and deliver and BUYER shall
not be obligated to purchase and receive the undelivered quantity of Product
that normally would have been sold and delivered during the period of force
majeure.

                                  ARTICLE XII
                         PRICE AND ALLOCATION CONTROLS

     12.1  Regulatory Price Suspension.  If SELLER is precluded by statute, or
by regulation, rule, interpretation or order implementing such statute from
obtaining any increase in Product Price, as determined pursuant to this
Contract, the increase shall be suspended until said law, regulation, rule,
interpretation or order permits the increase in whole or in part.  In the event
the law, regulation, rule, interpretation or order is terminated or is later
modified to permit the increase, in whole or in part, the Product Price shall be
increased for deliveries of the Product made thereafter to the level permitted
under this Contract without further action by the parties.

     12.2  Government Regulations.  If the delivery or supply of Product
pursuant to this Contract conflicts with or is limited or prohibited by any
federal, state or local regulations, then to the extent of such conflict,
limitation or prohibition, SELLER shall have no obligation to deliver or supply
BUYER with the Product under this Contract and BUYER shall have no

                                       20
<PAGE>
 
obligation to purchase or receive the Product under this Contract.  BUYER, in
BUYER's discretion, may elect to complete and file any and all required Federal
or state regulatory forms to permit, facilitate, or enable the supply of Product
to BUYER under this Contract.  SELLER shall fully cooperate with BUYER in the
completion and filing of the foregoing forms.

                                 ARTICLE XIII
                                  ASSIGNMENT

     This Contract shall not be assigned by either party without prior written
consent of the other party, and any assignment without such written consent,
shall be void; provided, however, BUYER may assign this Contract to the Trustee
under BUYER's First Mortgage Indenture dated December 1, 1938.

                                  ARTICLE XIV
                                APPLICABLE LAW

     This Contract shall be deemed to be a Contract made under and shall be
governed by and construed in accordance with the laws of the State of Hawaii.
The parties hereby consent to the personal jurisdiction of the federal and state
courts in the State of Hawaii.

                          PUBLIC UTILITIES COMMISSION

     This Contract is required to be filed with the Hawaii Public Utility
Commission (PUC) for approval.  If in the proceedings initiated as a result of
the filing of this Contract, the PUC disapproves or fails to authorize the
recovery of the fuel cost incurred under this Contract through the BUYER's
Energy Cost Adjustment Clause, BUYER may terminate this Contract at any time
within 90 days of disapproval by giving 60 days written notice to the SELLER.

                                  ARTICLE XVI
                    ENTIRE AGREEMENT, WAIVER AND ILLEGALITY

     This Contract incorporates the entire agreement between the parties with
reference to the subject matter and cancels and supersedes as of the date of
execution hereof all prior oral or written understandings, or agreements,
between the parties with respect to the subject matter and may only be modified
by written instrument executed by duly authorized representatives of the
parties.  There are no other agreements which constitute any part of the
consideration for, or any condition to, either party's compliance with its
obligations under this Contract.  Failure to insist upon strict performance of
any provision shall not constitute a waiver of the right to require such
performance, nor shall a waiver in one case constitute a waiver with respect to
a later breach, whether of a similar nature or otherwise.  If any term or
provision of this Contract is held by any Court to be illegal or unenforceable,
the remaining terms, provisions, rights and obligations shall

                                       22

not be affected.  The headings or captions are for  convenience  only  and  have
no  force  or effect  on legal meaning in the construction or enforcement of the
Contract.  Time shall be of the essence in this Contract.

     IN WITNESS WHEREOF, the parties hereto, intending to be legally bound
thereby, have caused this Contract to be executed in duplicate originals by
their duly authorized officers.

                  EXAMPLE DETERMINATION OF FREIGHT COMPONENTS

                     PURSUANT TO ARTICLE IV AND ARTICLE V

Article IV and Article V of this Contract provide for the determination of the 
price per physical barrel of LSFO; which price determination includes the use of
a tanker freight component which references the Worldscale 100 rate for voyages 
between Singapore and Barbers Point, Hawaii, expressed in New Worldscale rates, 
as published by Worldscape Associates (London) Limited in its New Worldwide 
Nominal Freight Scale ("Worldscale"). The current edition of Worldscale 
incorporates a Fixed Rate Differential to reflect the cost of additional 
insurance premiums for Oil Spill Liability Insurance on vessels carrying 
Persistent Oils applicable to voyages having a destination in the U.S.A. SELLER 
acknowledges that any vessel used to transport LSFO that is sold and purchased 
under this Contract, including its components and the crude oil from which the 
LSFO is derived, shall be required to possess oil spill liability insurance 
coverage in the amount of $700 million.

The price formula component "F5" refers to an AFRA rate applicable to a vessel 
size classification of LR-1, or Large Range 1. This vessel classification 
references tanker vessels ranging in size from 45,000 Long Tons Deadweight to 
79,999 Long Tons Deadweight. In order to derive an approximation of the 
relationship between Deadweight and Gross Registered Tons for a nominal vessel 
consistent with this vessel size classification, the average size 
characteristics of two vessels that have transported LSFO or crude oil to Hawaii
are used as reference data. These vessels are described as follows:

The Worldscale rate data that is to be included in the computation of tanker 
freight price formula components "FRD1" and "FRD2," consistent with the 
computation of "F5," is to be derived in the same manner as the following 
illustrative example calculations.

1.   Worldscale 100 rate in effect from February 20, 1995, onwards shall include
     Fixed Rate Differentials a. and b. below and shall be computed as follows:

          a.   Fixed Rate Differential with respect to the additional insurance 
               premiums for Basic $500 million coverage of Oil Pollution 
               Liability Insurance on vessels carrying Persistent Oils to and

     For informational purposes, the total applicable Fixed Rate Differential is
equal to $0.246 per Metric Ton, or $0.036 per barrel.

2.   The AFRA Worldscale Points and their related Worldscale 100 rate applicable
for each calendar quarter are based upon an average of the three monthly AFRA
publications in the calendar quarter immediately preceding the calendar quarter
of the nominated month of delivery. Therefore the relevant Fixed Rate
Differentials computed above may properly be prorated for certain quarterly
periods. Such proration may be computed as follows:

     A.   With respect to volumes of LSFO nominated during the three (3) months
          of the calendar quarter following a change in the published Worldscale
          rate (typically February of each year), the relevant Fixed Rate
          Differentials to be included in the computation of the tanker freight
          price formula component shall be prorated for illustrative purposes as
          follows:

          50/90 multiplied by the Fixed Rate Differential computed prior to the 
          rate change.

          and 40/90 multiplied by the Fixed Rate computed using the revised 
          rate.

     B.   With respect to volumes of LSFO nominated for subsequent months, and
          continuing for so long as the Fixed Rate Differentials as set forth
          in Worldscale Circular shall be applicable, the relevant Fixed Rate
          Differentials to be included in the computation of the price
          components "FRD1" and "FRD2" shall be as derived as in part 1 above.

                                     PRICE

SECTION 5.1
- -----------

     Effective January 1, 1996, or upon initial purchase and monthly thereafter,
the price of the Fuel Oil shall be the simple average of the high and low 
quotations for the Los Angeles Bunker C Fuel Oil as reported by the Platt's 
Bunkerwire on all dates of publication during the period beginning the 21st day 
of the second month preceding the month of delivery and ending the 20th day of 
the month preceding the month of delivery, expressed in U.S. dollars ("USD") per
barrel, converting to barrels from metric tons by dividing by 6.368, ----

     All prices, price formula, including their averages and factors,
adjustments thereto and other sums payable with respect to Fuel Oil hereunder
shall be stated in the nearest thousandth of a dollar unless specifically stated
otherwise.

     A sample calculation for the determination of the price of Fuel Oil as 
defined in this Section 5.1 is included in this Contract as Exhibit C.

SECTION 5.2
- -----------

     The price of Diesel during a calendar month shall be the simple average of 
the Average Weekly Prices for all Pricing Weeks the Thursday date (or, in the
event the Thursday price is not reported, the last reported date) of which fall
during the period beginning the 21st day of the second month preceding the month

<PAGE>
 
sulfur content of 0.5% by weight as assessed by Oil Price Information Service 
("OPIS") for Monday, Tuesday, Wednesday and Thursday of each week ("Pricing 
Week") shall comprise the "Average Weekly Price."

     If OPIS is not published or does not publish a high and low price for a 
particular Monday, Tuesday, Wednesday or Thursday during any particular week, 
the high and low prices for those days in the week for which OPIS does publish a
high and low price will be used in the calculation of the Average Weekly Price.

     All prices, price formula, including their averages and factors, 
adjustments thereto and other sums payable with respect to Diesel hereunder 
shall be stated in the nearest ten-thousandth of a dollar unless specifically 
stated otherwise.

     In addition to all other amounts payable by BUYER under this Contract, 
BUYER shall reimburse SELLER for all taxes, assessments, levies, and imposts of 
whatsoever kind or nature imposed on SELLER by any governmental or 
quasi-governmental body, including without limitation the Hawaii General Excise 
Tax, with respect to the execution or performance of this Contract or the 
receipt by SELLER of payments hereunder.  Notwithstanding the foregoing, BUYER 
shall not be required to reimburse SELLER for any tax measured by or based on 
the net income of SELLER or for real property taxes, or to duplicate any item of
expense of SELLER which is recovered by SELLER under the Product prices provided
for in Sections 5.1 and 5.2.  At

                                       5
<PAGE>
 
the execution of this contract, the taxes, etc. which are currently in effect 
include the Hawaii General Excise Tax (4.167%), the Superfund Petroleum Fee 
($0.097 per barrel or $0.0023 per gallon), the Hawaii Environmental Response Tax
($0.05 per barrel or $0.0012 per gallon) and Hawaii Liquid Fuel Tax ($0.0100 per
gallon). The Federal Oil Spill Liability Trust Fund Fee ($0.05 per barrel or
$0.0012 per gallon) is expected to go into effect January 1, 1996. The Hawaii
Environmental Response Tax and Hawaii Liquid Fuel Tax are not subject to Hawaii
General Excise Tax.

SECTION 5.4
- -----------

     OPIS and Platt's Bunkerwire shall include any successor publication(s) and,
in the event of discontinuance of these publications or assessments for No. 2 
Diesel having a maximum sulfur content of 0.5% by weight or Bunker C Fuel Oil, 
respectively, the parties shall agree upon the use of a similar reporting 
service.

SECTION 5.5
- -----------

     Should the gross heat content ("BTU content") per barrel of the 
representative sample of Fuel Oil drawn in accordance with the procedures set 
forth in Article VIII fall within the range of 6.2 Million ("MM") BTU per Bbl to
6.45 MM BTU per Bbl, no price adjustment will be made.  If the BTU content per 
barrel is below 6.2 MM BTU per Bbl, or above 6.45 MM BTU per Bbl, the price 
charged for the Fuel Oil delivered to BUYER shall be adjusted by multiplying the
price determined in Section 5.1, by the ratio of the actual heat content to 
6.325 MM BTU per Bbl.  A sample calculation for the determination of the price 
adjustment for Fuel Oil as defined in this Section 5.5 is included in Exhibit C 
of this Contract.

                                       6
<PAGE>
 
     Should the BTU content per gallon of the representative sample of Diesel 
drawn in accordance with the procedures set forth in Article VIII fall within
the range of 137,000 to 141,000, no price adjustment will be made. If the BTU
content per gallon is below 137,000, or above 141,000, the price charged for the
Diesel delivered to BUYER shall be adjusted by multiplying the price determined
in Section 5.2, by the ratio of the actual heat content to 139,000 BTU. A sample
calculation for the determination of the price adjustment for Diesel as defined
in this Section 5.5 is included in Exhibit D of this Contract.

     The official heat content determination shall be based upon SELLER's
laboratory results provided that the arithmetic difference between SELLER's and
BUYER's laboratory results is equal to or less than the then existing ASTM
reproducibility standard (currently 0.40 MJ/kg) for test D-240. If the
difference between SELLER's and BUYER's laboratory results for measured gross
heat content should be greater than the reproducibility standard for ASTM test
D-240, the parties will confer, in good faith, to resolve the difference. In the
event of an unresolvable difference between BUYER and SELLER, BUYER's sealed
Barge Tank Samples (as defined in Section 8.3), and also BUYER's sealed Retain
Samples (as defined in Section 8.3) if relevant in the opinion of the
Independent Inspector, will be provided to an independent laboratory for a final
determination, which shall be binding upon the parties. SELLER and BUYER shall
share equally the costs of independent tests determinations.

                                Account #4064332

     If SELLER's final laboratory result for gross heat content is unavailable
or if said laboratory result is disputed by BUYER pursuant to Article VIII,
SELLER may issue a provisional invoice calculated on the basis of the Diesel and
Fuel Oil heat-content standards pursuant to Article V.  BUYER shall make payment
for such provisional invoice in accordance with the instructions of this Section
6.1.  If an invoice incorporating an item other than a heat rate adjustment
which is disputed has been sent to BUYER, then BUYER shall make payment in
accordance with the instructions in this Section 6.1 for such invoice items or
that portion of the invoiced Delivery which is not disputed by BUYER and in
which case BUYER shall make such adjustment to taxes and other value-dependent
items as are reasonable under the circumstances.

The provisional invoice or invoice incorporating items in dispute shall be
adjusted in accordance with the terms of Article V by subsequent invoicing or by
issuing a credit or debit with respect to the original invoice within 7 business
days of receipt of the independent laboratory determination pursuant to Article
VIII or other resolution of the issue in dispute.  BUYER shall make payment for
such subsequent invoices or debits in accordance with the instructions in this
Section 6.1.  BUYER shall have the option to apply such credit against payments
to be made subsequent to the receipt of the credit, or if such payments are not
expected to be made within 15 calendar days, BUYER shall be able to receive said
credit in immediately available funds within 3 business days of SELLER's receipt
of BUYER's written instructions.

     At SELLER's option and election, interest will accrue on all amounts not
paid within 15 days of the date of the invoice at the then existing LIBOR.

onto BUYER's nominated barge, allowable laytime shall be prorated and BUYER's
allowable laytime shall be calculated on the basis of the ratio of the bill of
lading volume of BUYER's cargo to the total bill of lading volume of the entire
cargo loaded onto BUYER's nominated barge or vessel.  Laytime shall cease when
the hoses are disconnected; however, in the event part cargoes are loaded for
BUYER and a third party or parties,  BUYER's laytime shall commence as provided
above if BUYER's cargo is loaded first, or shall commence upon commencement of
loading of BUYER's cargo if BUYER's cargo is not the first to be loaded, and
shall cease upon completion of loading of BUYER's cargo.  Laytime is allotted
and calculated using the barge currently named NOHO HELE (having approximately a
56,000 Bbl capacity).  In the event that BUYER's nominated tank vessel is other
than the NOHO HELE, laytime shall be the capacity of

                                       13
<PAGE>
 
the substitute tank vessel divided by 4,000 Bbl per hour; e.g., a 40,000 Bbl 
barge shall have an allocable laytime of 10 hours.

     Demurrage shall be payable at a rate equal to BUYER'S actual cost of tug 
and tow per hour for each hour used and prorated for each portion of an hour 
used in excess of allowable laytime. In the event the condition of Buyer's 
nominated barge renders it incapable of receiving cargo at the minimum delivery 
rate, such that the time spent loading BUYER's nominated barge (all cargoes) is 
in excess of nineteen (19) hours, SELLER shall have the right to suspend loading
operations and order BUYER's nominated barge to vacate SELLER's Loading Pier or 
Third-Party Pier. SELLER shall not be liable for demurrage to the extent that
allowed laytime is exceeded due to the condition of BUYER's nominated barge or
tug, or is due to events or acts beyond SELLER's reasonable control.

SECTION 7.4

     While it is the intention of the parties to make deliveries of Product at
SELLER's Loading Pier or Third-Party Pier, subject to mutual agreement,
deliveries may be made at SELLER's SPM. In addition to those provisions of this
Article VII not specific to SELLER's Loading Pier or Third-Party Pier, the
following additional provisions will also apply to these SPM deliveries.

     SELLER agrees to make best, reasonable effort to deliver Fuel Oil into the
BUYER's nominated barge at a temperature above 110 deg. F.  BUYER's nominated
barge shall operate in compliance with SELLER's Operations Manual approved by
the U.S. Coast Guard and shall also comply with SELLER's current requirements
for loading at its SPM as amended from time to time.  SELLER may refuse to berth
or load BUYER's nominated barge at SELLER's SPM for

                                       14
<PAGE>
 
failure to comply with SELLER's Operations Manual or requirements as aforesaid
and shall not be liable for any resulting delays or expenses of BUYER.

     An accepted delivery day shall be determined in respect of each SPM loading
pursuant to the provisions of this section.  BUYER shall provide SELLER a
proposed 3-day delivery window upon no less than seven (7) days' notice from the
first proposed delivery day.  The notice shall also specify the amount of the
Product to be delivered, subject to a variation of plus or minus ten (10)
percent at BUYER's option.  The delivery window shall be narrowed to two (2)
days upon no less than three (3) days' notice from the first proposed delivery
day and one (1) day upon no less than two (2) days' notice from the first
proposed delivery day.  A final 24 hour accepted delivery day will be set by
mutual agreement upon receipt of the two (2) day notice.  SELLER may reject the
final proposed delivery day upon providing BUYER 24 hours notice, with an
alternate delivery day being set within one (1) day of BUYER's proposed delivery
day.  Notices may be given by telex, facsimile, radio or telephone.

     When BUYER's nominated barge is ready to load, the master of the barge's
tug shall provide SELLER notice of readiness (NOR), and laytime shall commence
six (6) running hours after receipt of the NOR, or upon the barge's arrival in
berth (all fast), whichever first occurs.  SELLER shall be allowed 24 hours
laytime for loading the entire cargo requested in the seven (7) days' notice.

     BUYER's nominated barge shall vacate the SPM as soon as loading is
completed.  BUYER shall be responsible for any actual loss or damage incurred by
SELLER as a direct result of the failure of BUYER's nominated barge to promptly
vacate the SPM except if such delay is

                                       15
<PAGE>
 
caused by any event or acts beyond the reasonable control of BUYER, including
but not limited to acts of God, fire, governmental acts or labor disturbances.
In no event shall either party be responsible for prospective profits, or
consequential damages allegedly caused by or based upon failure of BUYER's
nominated barge to promptly vacate the SPM.

SECTION 7.5

     When an escape or discharge of oil or any polluting substance occurs in
connection with or is caused by BUYER's nominated barge or its tow, or occurs
from or is caused by loading operations, BUYER or its agents shall promptly take
whatever measures are necessary or reasonable to prevent or mitigate
environmental damage, without regard to whether or not said escape or discharge
was caused by a negligent act or omission of BUYER's nominated barge or SELLER
or BUYER or others.  Failing such action by BUYER or its agents, SELLER, upon
notice to BUYER and on BUYER's behalf, may promptly take whatever measures are
reasonably necessary to prevent or mitigate pollution damage.  Each party shall
keep the other advised of the nature and results of the measures taken, and if
time permits, the nature of the measures intended to be taken.  Each party shall
provide notice to the other pursuant to Section 15.2 or as otherwise  provided
in writing from time to time during the term of this Contract.  The cost of all
such measures taken shall be borne by BUYER except to the extent such escape or
discharge was caused or contributed to by SELLER, and prompt reimbursement shall
be made as appropriate; provided, however, that should BUYER or its agents give
notice to SELLER to discontinue said measures (and to the extent government
authorities allow SELLER to discontinue said measures) the continuance of
SELLER's actions will no longer be deemed to

                                       16
<PAGE>
 
have been taken pursuant to the provisions of this clause.  Notwithstanding any
other provision in this Contract, the foregoing provisions shall be applicable
only between BUYER and SELLER and shall not affect, as between BUYER and SELLER,
any liability of BUYER to any third parties, including the State of Hawaii and
the U.S. Government, if BUYER shall have such liability.

     Should SELLER incur any liability under Chapter 128D of the Hawaii Revised
Statutes as a result of a spill from BUYER's nominated barge during transport,
BUYER shall indemnify and hold SELLER harmless to the extent not caused by
SELLER's negligence.

     BUYER warrants that any vessel used to load Product purchased from SELLER
shall have in place Primary and Excess full Form Protection and Indemnity
insurance including cover for Oil Pollution Clean-Up Liability and Liability for
Oil Pollution Damage with a policy limit of $700,000,000, or the maximum
available, as reflected by the coverage carried by other vessels calling at
SELLER's SPM.

                                 ARTICLE VIII
                       MEASUREMENT, SAMPLING AND TESTING

SECTION 8.1

     A mutually agreed upon independent petroleum inspector (Independent
Inspector) shall attend every Product Delivery.  A Delivery is defined as
beginning with the initiation of pumping of each of Diesel or Fuel Oil from
SELLER's refinery tank or nominated issuing tank to BUYER's nominated vessel and
ending with the subsequent cessation of continuous pumping of Diesel or

                                       17
<PAGE>
 
Fuel Oil in such amount as is determined by the Independent Inspector's
Certificate of Quantity.  Reasonable charges rendered by the Independent
Inspector shall be borne equally by BUYER and SELLER.

SECTION 8.2

     Quantity determination will be made by the Independent Inspector gauging
SELLER's Product shore tanks before and after delivery.  BUYER may verify
SELLER's tank strapping tables at BUYER's election and sole expense.

     All measurements shall be made on the basis of net standard volumes in
barrels corrected to 60 degrees Fahrenheit using the applicable ASTM-IP volume
correction factor tables and should state whether such volumes are measured in
air or in vacuum, with conversion in accordance with the most recent ASTM-IP
Petroleum Measurement Tables (IP200) issued at the date of loading and otherwise
by manual measurements such as ASTM-IP, Chapter 17 Procedures.

     The Independent Inspector shall (1) prepare and sign a certificate stating
the quantity of the load, such certificate to utilize ASTM-IP standards,
including measurement of sediment and water and API specific gravity, (2)
furnish BUYER and SELLER each with a copy of such certificate; and (3) cable or
advise by facsimile the quantity loaded to BUYER and SELLER.  The data in the
inspector's certificate of quantity prepared as provided herein shall, absent
fraud or errors and omissions, be binding and conclusive upon both parties, and
shall be used for verification of the invoice and Bill of Lading.

                                       18
<PAGE>
 
SECTION 8.3

     Unless otherwise specifically provided herein, quality and heat content
determination shall be based upon composite samples drawn from SELLER's issuing
tanks and pipeline in accordance with ASTM sampling procedures in such a manner
as to be representative of each individual Delivery of Fuel Oil and Diesel,
respectively.  If a Delivery of Diesel or Fuel Oil is from more than one issuing
tank, the specifications of the total Delivery of Diesel or Fuel Oil shall be
determined on a volumetric weighted average basis.

     The Independent Inspector shall draw (a) composite samples of diesel and
fuel oil retain ("Retain Samples") prior to the loading of BUYER's nominated
barge, if such diesel and fuel oil retain is accessible to standard sampling
equipment, and (b) barge tank composite samples ("Barge Tank Samples") at the
completion of loading the Diesel and at the completion of loading the Fuel Oil
onto BUYER's nominated barge, in such a manner as to be representative of the
total volume of diesel and fuel oil retain and of each individual Delivery,
respectively.  The samples described in subsections (a) and (b) herein shall be
divided into a minimum of three (3) parts:

     1.  One part shall be retained by SELLER's laboratory for a period of three
(3) months.

     2.  One part shall be provided to BUYER for the purpose of verifying
SELLER's determinations.

     3.  At least one part shall be sealed and provided to BUYER, or to the
Independent Inspector, to be retained.

                                       19
<PAGE>
 
     SELLER agrees to provide BUYER a copy of SELLER's laboratory analyses of
the issuing tank and pipeline samples showing API gravity, sulfur content, flash
point and sediment and water content prior to commencing Delivery.  SELLER shall
provide BUYER the complete Certificate of Quality of the Diesel and the Fuel Oil
no later than two working days after the completion of the Delivery.  BUYER
shall have the right to perform laboratory analyses in order to verify the
results of SELLER's laboratory analyses.

     If SELLER or BUYER has reason to believe that the quality or quantity of
Product stated for a specific Delivery is incorrect, including a dispute as to
the test results of BUYER's samples and SELLER's shore tank and pipeline
samples, then that party shall within thirty (30) days after the later of the
date of the complete Certificate of Quality or the date of the final
determination of gross heat content, present the other party with documents
supporting such determination and the parties will confer, in good faith, on the
causes for the discrepancy and shall proceed to correct such causes and adjust
the quality and quantity, if justified, for the Delivery in question.  In the
event of an unresolvable difference between SELLER and BUYER, BUYER's sealed
Barge Tank Samples, and also BUYER's sealed Retain Samples if relevant in the
opinion of the Independent Inspector, shall be provided to an independent
laboratory for a final determination, which shall be binding on the parties.
SELLER and BUYER shall share equally the cost for such independent laboratory
determination.

     In the event of any quality problems occurring, both SELLER and BUYER shall
attempt to minimize the impact of any such quality problems.  If efforts to
resolve the quality problem fail, BUYER may return off-specification loaded
Product to the SELLER's Barbers Point

                                       20
<PAGE>
 
refinery, in which case SELLER shall replace the off-specification Product by
delivering an equal volume of Product into BUYER's nominated barge in a timely
manner.

     All reasonable costs and expenses, including testing, transportation, 
re-refining, and handling costs incurred in returning and replacing off-
specification Product shall be paid by the responsible party, as determined by
the independent laboratory test results and any other applicable evidence.  In
no event shall either party be responsible for prospective profits, or
consequential damages allegedly caused by or based upon any quality problem with
the Product.

                                  ARTICLE IX
                                 RENEGOTIATION

     It is understood and agreed that both parties entered into this Contract in
reliance on governmental laws, rules, decrees, orders, regulations, and
interpretations or implementation thereof in effect on the date of execution of
this Contract or any subsequent amendments hereto, to the extent that they
directly or indirectly affect the Product sold or purchased hereunder.  If at
any time any of the said laws, rules, regulations, implementations or
interpretations thereof are changed or if new laws, rules, regulations or new
interpretations and implementations thereof become effective, and such change or
new laws, rules, regulations, interpretations or implementations thereof have a
significant adverse economic effect upon either party such that performance of
this Contract would be inequitable or cause substantial financial hardship to
the affected party, then the affected party shall have the option to call for
renegotiation of the price of the Product or any other provision of this
Contract the performance of which by the affected

                                       21
<PAGE>
 
party would be inequitable or cause substantial financial hardship.  Such option
shall be exercised by the affected party at any time after such a change or new
law, rule, regulation, interpretation or implementation thereof is effective, by
giving written notice to the other party of the call to renegotiate.  Within ten
(10) calendar days after the date of such notice, the parties shall enter into
negotiations and in the event that the parties do not agree upon a new price for
the Product or other provision satisfactory to both parties within forty (40)
calendar days after the date of such notice, the affected party shall have the
right to terminate this Contract effective thirty (30) days after giving notice
of termination to the other party.  Said notice of termination shall be given
within thirty (30) days immediately following the forty (40) day negotiation
period.  Until a mutually satisfactory new price for the Product or other
provision has been agreed upon, or until this Contract is terminated as provided
herein, the price for the Product or other provision which was in effect when
the request for renegotiation was made shall continue in full force and effect.

                                   ARTICLE X
                                 FORCE MAJEURE

SECTION 10.1

     Force Majeure.  As used in this contract, an event or act of "force
majeure" is defined as follows:  acts of God, wars, riots, strikes, labor
disputes, lockouts, blockades, insurrections, inability to secure materials or
labor by reason of allocations promulgated by governmental

                                       22
<PAGE>
 
agencies, epidemics, landslides, lightning, earthquakes, fires, floods, tidal
waves, volcanic eruptions, explosions, or any other causes not within the
control of the affected party.

SECTION 10.2

     Obligations Suspended.  BUYER's obligation to purchase or receive Product,
or SELLER's obligation to sell or deliver Product, shall be suspended to the
extent performance is prevented by an event or act of force majeure for any
period in which such event or act exists as to the party claiming force majeure;
and so long as such party is exercising its good faith efforts to overcome such
force majeure event.  However, nothing in this Article excuses BUYER from its
obligation to make payments of money due SELLER for Product already delivered to
BUYER.

SECTION 10.3

     Notice of Force Majeure.  The party claiming force majeure agrees to give
the other party prompt written notice of an act or event of force majeure.  The
party claiming force majeure shall use due diligence to cure any act or event of
force majeure, and shall give the other party prompt notice after the act or
event of force majeure has terminated.  This Article shall not require any party
to settle or compromise any strike or labor dispute.

SECTION 10.4

     No Make-Up Requirement.  After the act or event of force majeure has
terminated, SELLER shall not be obligated to sell and deliver and BUYER shall
not be obligated to purchase and receive the undelivered quantity of Product
which normally would have been sold and delivered during the period of force
majeure.

                         PRICE AND ALLOCATION CONTROLS

SECTION 11.1

     Regulatory Price Suspension.  If SELLER is precluded by statute, or by
regulation, rule, interpretation or order implementing such statute from
obtaining any increase in Product Price, as determined pursuant to this
Contract, the increase shall be suspended until said law, regulation, rule,
interpretation or order permits the increase in whole or in part.  In the event
the law, regulation, rule, interpretation or order is terminated or is later
modified to permit the increase, in whole or in part, the Product Price shall be
increased for deliveries of the Product made thereafter to the level permitted
under this Contract without further action by the parties.

SECTION 11.2

     Government Regulations.  If the delivery or supply of Product pursuant to
this Contract conflicts with or is limited or prohibited by any federal, state
or local regulations, then to the extent of such conflict, limitation or
prohibition, SELLER shall have no obligation to deliver or supply BUYER with the
Product under this Contract and BUYER shall have no obligation to purchase or
receive the Product under this Contract.  BUYER, in BUYER's discretion, may
elect to complete and file any and all required Federal or state regulatory
forms to permit, facilitate, or enable the supply of Product to BUYER under this
Contract.  SELLER shall fully cooperate with BUYER in the completion and filing
of the foregoing forms.  If purchase and receipt of Product pursuant to this
contract conflicts with or is limited or prohibited by any

                                       24
<PAGE>
 
Federal, State, or local regulations, then to the extent of such conflict,
limitation, or prohibition, BUYER shall have no obligation to purchase and
receive the Product under this Contract.

                                  ARTICLE XII
                                  ASSIGNMENT

     This Contract shall not be assigned by either party without prior written
consent of the other party, and any assignment without such written consent
shall be void; provided, however, HECO, HELCO, and MECO may assign their
interests in this Contract to the Trustee under their respective First Mortgage
Indentures.

                                 ARTICLE XIII
                                APPLICABLE LAW

     This Contract shall be deemed to be a Contract made under and shall be
governed by and construed in accordance with the laws of the State of Hawaii.
The parties hereby consent to the personal jurisdiction of the federal and state
courts in the State of Hawaii.

                                  ARTICLE XIV
                     PUBLIC UTILITIES COMMISSION APPROVAL

     This Contract is required to be filed with the Hawaii Public Utilities
Commission for approval.  If in proceedings initiated as a result of the filing
of this Contract, the Public Utilities Commission disapproves or fails to
authorize the recovery of fuel costs incurred under this

                                       25

Contract through the BUYER's Energy Cost Adjustment Clause, BUYER may terminate
this Contract at any time within ninety (90) days of disapproval by giving sixty
(60) days written notice to the SELLER.

                                  ARTICLE XV
                    ENTIRE AGREEMENT, WAIVER AND ILLEGALITY

SECTION 15.1

     This Contract incorporates the entire agreement between the parties with
reference to the subject matter and cancels and supersedes as of the date of
execution hereof all prior oral or written understandings, or agreements,
between the parties with respect to the subject matter and may only be modified
by written instrument executed by duly authorized representatives of the
parties.  There are no other agreements which constitute any part of the
consideration for, or any condition to, either party's compliance with its
obligations under this Contract.  Failure to insist upon strict performance of
any provision shall not constitute a waiver of the right to require such
performance, nor shall a waiver in one case constitute a waiver with respect to
a later breach, whether of a similar nature or otherwise.  If any term or
provision of this Contract is held by any Court to be illegal or unenforceable,
the remaining terms, provisions, rights and obligations shall not be affected.
The headings or captions are for  convenience  only  and  have  no  force  or
effect  on legal meaning in the construction or enforcement of the Contract.
Time shall be of the essence in this Contract.
