9.   QUARTERLY QUALITY AND QUANTITY RECONCILIATION

     a)   Quarterly Reconciliation
          There will be a quarterly reconciliation and quantity and quality for
          the purpose of reconciling the actual quantity and quality of product
          consumed or lost by ICI as against the quantity of product nominated
          by ICI. Reconciliation takes place once every quarter, however within
          the reconciliation process the quantity reconciliation reference
          period is the month and the quality reconciliation reference period is
          the quarter.

     b)   ICI will declare the reconciliation payment due (from STIL to ICI, or
          from ICI to STIL as the case may be) for any quarter to STIL on or
          before the 10/th/ day of the first month following that quarter. This
          declaration ('Quarterly Reconciliation Declaration') will include:

                                       12


          (i)   Declaration of quantities consumed or lost during the quarter
          (ii)  Declaration of reconciliation payment required for quantity
          (iii) Declaration of reconciliation payment required for quality
          (iv)  Declaration of total reconciliation payment due
          (v)   Details of calculations used to compute the reconciliation
                payment due

          The reconciliation payment will be referred to as the 'Total
          Reconciliation Payment'.

     c)   Any reconciliation payment shall be made [+++++] the period of
          reconciliation.

     d)   The financial reconciliation involves three steps designed to
          calculate the payment due for the Net Amount Utilised during the
          previous calendar quarter:

          (i)   Quantity reconciliation -- calculating the 'Quantity
                Reconciliation Payment'
          (ii)  Quality reconciliation -- calculating the 'Quality
                Reconciliation Payment'
          (iii) Overall financial reconciliation -- calculating the "Total
                Reconciliation Payment'
          The total financial amount generated by those three steps represents
          the reconciliation payment in its entirety.


     e)   Process
          ICI will maintain a database of daily and cumulative delivery
          (quantity and quality); and daily consumption and loss.  The data will
          be based on the following sources:

          (i)   Delivery data: based on the Certificate of Quantity and Quality.
          (ii)  Consumption and loss: calculated an a daily basis based on:
                daily stock deltas based on ICI daily stock dip; and quantity
                and quality of products discharged, determined by the
                Certificate of Quantity and Quality
          This database will be used to calculate the actual quantity and
          quality of the Net Amount Utilised during the quarter. Main outputs
          will be

                                       13


          monthly and quarterly quantities of the Net Amount Utilised, and
          cumulative quality of material delivered in the quarter ('Quarterly
          Quality') on FIFO (First In First Out) basis as described in Clause 9
          g) of this Agreement. The data will be kept substantially in the
          format set out in Appendix 7a.


     f)   The Quantity Reconciliation Process
          The quantity reconciliation payment is the difference between the
          amount invoiced for the quarter, and the value of the Net Amount
          Utilised during the quarter. The value of the Net Amount Utilised
          during each month shall be determined by multiplying the prices for
          the nominated Optimix quality during the same month (in accordance
          with Appendix 2); and Net Amount Utilised during each month (as
          calculated from the ICI database detailed in Clause 9 e) above, and
          declared in the Quarterly Reconciliation Declaration). These monthly
          values of the Net Amount Utilised shall then be summed to give the
          quantity reconciliation value during the quarter.

     g)   The Quality Reconciliation Process
          The quality used during the quarter shall be determined on the basis
          of FIFO, the product shall be deemed to be removed from the storage
          tanks in the same order in which that product was delivered into those
          tanks (including any product carried forward from the previous
          quarter). Any product for which payment was not made by ICI during the
          quarter shall be carried forward into the next quarter.

          The quality is determined by the [+++++] For each component, the
          difference between the content for the nominated Optimix quality, and
          its content in the Net Amount Utilised in the quarter, is [+++++]


          to give a reconciliation payment for each component.  The
          reconciliation payments for each of the four components are then
          summed to give the quality reconciliation payment.

     h)   The Overall Financial Reconciliation

          The 'Total Reconciliation Payment' is determined by the sum of the
          Quantity Reconciliation Payment and the Quality Reconciliation
          Payment. These payments are defined in the sections above.

                                       14


     i)   The detailed methodology is defined in Appendix 5.

          Each calculation to be made under this Clause 9 shall be calculated to
          two (2) decimal places and the following arithmetic rules shall be
          applied to do this:

          (i)  If the third decimal place is five (5) or greater than five (5)
               then the third decimal place shall be rounded up to the next
               digit.

          (ii) If the third decimal place is four (4) or less then four (4) then
               the third decimal place will be unchanged.


     j)   Any dispute between the parties arising under this Clause 9 shall be
          referred to an expert for determination pursuant to Clause 21 c) of
          this Agreement


10.  MEASUREMENT, SAMPLING AND TESTING

     a)   The quantity of STIL Product discharged and ICI Product loaded shall
          be that discharged or loaded at the place of delivery and shall be
          based on North Tees Works port meter measurements in accordance with
          API MPMS Chapter 5 or in the absence of port meters, the meters of any
          delivering or receiving vessels. Meters shall be proved on each
          delivery in accordance with API MPMS Chapter 4, except as set forth
          below.

     b)   The quantity and quality of products shall be determined at the place
          of delivery by an independent Inspector instructed in accordance with
          the Agreement and who is satisfactory to both ICI and STIL. Unless
          otherwise agreed STIL will appoint and instruct the Inspector and the
          charges of the Inspector to so act shall be shared equally between ICI
          and STIL. Any charges of the Inspector for performing duties not
          specified in the Agreement will be for the account of the party so
          instructing the Inspector.

     c)   The Inspector shall be instructed to issue and send a telex, cable or
          facsimile showing the quantity and quality of products discharged

                                       15


          and/or loaded to STIL and ICI immediately upon completion of discharge
          or loading of the products and then issue, sign and send the
          Certificate of Quantity and Quality showing the quantity and quality
          of products to ICI and STIL as soon as possible thereafter. The
          Certificate of Quantity and Quality issued shall state the methodology
          and show the calculations used to determine the quantity and quality
          of products.

     d)   The results of measurement, sampling and testing as evidenced by the
          Inspector's certificate shall, for the purposes of this Agreement, be
          treated as conclusive as to the quantity and quality of products
          discharged or loaded, save for fraud or manifest error.

     e)   ICI shall ensure that both the Inspector and STIL's representative has
          full access to any part of the products handling or storage facilities
          deemed necessary by the Inspector or STIL's representative in order to
          determine the quantity and quality of the products discharged or
          loaded. The Inspector shall take and retain two sealed, labelled and
          dated samples from vessel tanks, discharging or loading line and
          receiving tanks for each grade of products delivered under this
          Agreement.

     f)   On every occasion the Inspector takes any other samples in accordance
          with the methodology and procedures described in this Agreement, the
          Inspector shall take two further samples which shall be sealed,
          labelled, dated and retained. STIL, ICI or their respective
          representatives may instruct the Inspector to take and retain other
          samples. The Inspector shall be instructed to retain samples for at
          least 90 days from completion of discharge or loading date and may be
          instructed to retain them for a longer period by ICI or STIL or their
          respective representatives.

     g)   ICI will give or will procure that STIL's representative and the
          Inspector are given full access to and copies of the latest records
          covering the maintenance, calibration and proving of all equipment
          used to determine the quantity of products discharged or loaded in
          order to record that such equipment is in the opinion of the Inspector
          and STIL's representative in a suitable condition to determine
          accurately the quantity of Products discharged or loaded.

                                       16


     h)   For products delivered from STIL's vessel directly into static shore
          tanks (that is shore tanks to or from which no products are being
          pumped other than the products being delivered under this Agreement)
          and where metering facilities are not available, or where in the
          opinion of the Inspector the meter did not perform in accordance with
          API MPMS Chapter 5, or where the meters were not proven for that
          delivery in accordance with API MPMS Chapter 4, the quantity of
          products shall be based on discharge port shore tank gaugings in
          accordance with API MPMS Chapter 3.

          For ICI Products delivered to STIL's vessel directly from ICI's static
          shore tanks (that is shore tanks to or from which no products are

               full storage capacity as defined in Clause 5 a).
          (iv) The date at which ICI may start taking STIL Products from the
               Tank Stocks defined as the On Stream Date shall be agreed between
               the parties but may not fall within the first 20 days following
               the Stock Build Date.

     e)   Notwithstanding Clause 13 d) ICI and STIL shall use their reasonable
          endeavors to accommodate early delivery of reformate and heart-cuts in
          the second and third quarters of [+++++]. Those deliveries shall be
          paid on the [+++++] and such volumes of pre-deliveries shall be taken
          into account as deliveries during the fourth quarter for nomination
          and reconciliation purposes. ICI shall pay for the Tank Heels on the
          [+++++]. The reconciliation process for the fourth quarter of 1999
          will comprise the Tank Heels, the Minimum Operating Stock and the
          quantity consumed or lost by ICI. An example of this process for
          illustrative purposes is contained in Appendix 7b.

     f)   At the termination or other ending of this Agreement, there shall be a
          final reconciliation in accordance with Clause 9 of this Agreement.

                                       20


          ICI shall pay STIL for any product delivered by STIL for which payment
          has not been made. Payment shall be due [+++++] ("Bill of Lading") of
          the last delivery of STIL product. An example of this process for
          illustrative purposes is contained in Appendix 7c.

     g)   Both parties acknowledge that during the transition period as being
          the fourth quarter of [+++++] it may be at times difficult to meet the
          cargo tolerances as specified in Appendix 4 and the C9 specification
          in terms of lead as set forth in Appendix 3. The parties will
          cooperate to mitigate any consequences.


14.  INVOICING AND PAYMENT

     a)   STIL Products
          As soon as reasonably possible after the end of each month, STIL shall
          issue an invoice to ICI (Facsimile accepted) calculated with reference
          to the monthly STIL Products Nomination for that month as defined in
          Clause 6 g).  The price of the Benzene Heartcut and Benzene/Toluene
          Heartcut components of the STIL Product Nomination Split shall be
          calculated with reference to the [+++++] described in Appendix 2.  For
          all STIL Products the price formulas as defined in Clause 8 above
          apply.  An example of the monthly payment calculation is set forth in
          Appendix 7.  Such invoice shell be paid by ICI to STIL [+++++].

     b)   ICI Products
          As soon as reasonably possible after the end of each month, ICI shall
          issue an invoice to STIL (Facsimile accepted).  For all ICI Products
          the price formulas as defined in Clause 8 above apply.
          Such invoice shall be paid by STIL to ICI [+++++].

     c)   Provisional Invoicing
          Where the pricing terms for the product to be supplied hereunder do
          not allow and/or, where needed hereunder, the Inspector's discharged
          quantity figures are not available in time for a final invoice to be
          dispatched in time for payment to be made by the due date, either
          party may invoice the other on a provisional basis.  In the case of a
          provisional invoice, the loaded quantity will be used and a document
          recording the loaded details presented to that other party instead of
          the

                                       21


          discharge details as described in Clause 10. A final invoice will be
          dispatched as soon as is practical thereafter.

          Any resultant additional payment or overpayment will be paid
          immediately by the relevant party to the other.

     d)   Each quarter, a reconciliation shall be conducted as set forth under
          Clause 9 and shall be due for payment on or before [+++++].

     e)   Unless otherwise agreed the payment of any other costs, expenses or
          charges which arise under the terms of this Agreement shall be made
          against presentation of the payee's invoice (following the incurring
          of such costs, expenses or charges) and shall be for immediate
          settlement by the payer on or by the date advised thereon.

     f)   All payments to be made by ICI to STIL under this Agreement shall be
          made free of all charges and without asserting at the time for payment
          any set off, counterclaim or right to withhold whatsoever, unless
          specifically permitted hereunder, in United States Dollars in New York
          to STIL's account number [+++++] with the [+++++] (or to such other
          bank account as may be advised by STIL to ICI from time to time)
          quoting STIL's invoice number and ICI's name.

          All payments to be made by STIL to ICI under this Agreement shall be
          made free of all charges and without asserting at the time for payment
          any set off, counterclaim or right to withhold whatsoever, unless
          specifically permitted hereunder, in United States Dollars direct to
          [+++++] for credit to ICI Petrochemicals account number [+++++] (or to
          such other bank account as may be advised by ICI to STIL from time to
          time) quoting ICI's invoice number and STIL's name.

     g)   Unless otherwise agreed in writing [+++++]

     h)   The foregoing shall not be construed as an indication of any
          willingness on the part of either party, to provide extended credit as
          a matter of course and shall be without prejudice to any rights and
          remedies which that party may have under this Agreement or otherwise.

     i)   Where the last day for payment falls on a Saturday or on a weekday
          other than Monday which is not a banking day in such place as may be

                                       22


          designated by the recipient party for payment, then any such payment
          shall be made on the nearest preceding banking day. Where the last day
          for payment falls on a Sunday or a Monday which is not a banking day
          in such place so designated, then any such payment shall be made on
          the next following banking day.


15.  TAXES AND DUTIES

     a)   All taxes, duties, charges or imposts, whether retroactive or not,
          which are levied in the country in which the Products are discharged
          on or by reference to, or on or by reference to amounts payable with
          respect to the Products or the vessel (other than those defined by
          Worldscale for owners' account) shall be for purchaser's account, and
          the purchaser of each Product shall reimburse the seller for the full
          amount of any such taxes, duties, charges or imposts which the seller
          is obliged to pay.

     b)   The purchaser of each product will obtain at its own risk and expense
          any import license or other official authorization necessary for the
          importation of the goods.

     c)   Without prejudice to the above, as between the parties to the
          Agreement the purchaser of each product shall be responsible for
          complying with Customs entry procedures at the discharge port and
          liable to Customs authorities for all duties and taxes that arise in
          respect of such Customs entry.

     d)   In the absence of a declaration by STIL to the contrary, STIL hereby
          declares that ICI Products taken by STIL are for delivery outside of
          the UK.
16.  ASSIGNMENT/CHANGE OF REFINERY OWNERSHIP

     a)   Any assignment of this Agreement shall be by novation agreement.
          Neither party shall assign this Agreement without the consent of the
          other party, such consent and agreement to novate not to be
          unreasonably withheld.

     b)   If at any time STIL shall announce an intent to sell or close one or
          more of the named refineries, STIL will have the right to terminate

                                       23


          this Agreement upon giving not less [+++++]. Promptly following
          notice, the parties shall meet and discuss the implications thereof
          and shall seek to agree appropriate amendments to this Agreement to
          avoid the termination. In the absence of agreement and provided that
          there is a sale or closure of any one or more of the named refineries,
          this Agreement shall terminate in accordance with the notice.


17.  LIABILITIES

     a)   Except as specifically hereinafter provided, neither party shall be
          liable to the other (whether in contract, negligence and/or tort) for
          any indirect, special or consequential losses or damages, other than
          as specifically set forth herein.

     b)   Any claim in respect of a shortage in quantity or defeat in the
          quality of products will only be considered by the seller of such
          product if notice in writing of such claim is received by the seller
          within forty-five (45) days after the Bill of Lading date (Bill of
          Lading date equals day zero) for the particular cargo and such notice
          is followed by a fully documented claim to be received by the seller
          within sixty (60) days after the Bill of Lading date (Bill of Lading
          date equals day zero). If the buyer fails to give notice of or to
          submit any such claim within the time limits, the buyer's claim is
          deemed to be waived and any liability on the part of the seller
          extinguished.

     c)   If STIL shall default in the delivery of STIL Products, ICI shall be
          entitled:

          (i)  to acquire substitute products from a third party or third
               parties; and/or
          (ii) to acquire downstream products that would otherwise had been
               derived from STIL Products

          and, except as limited below, all additional costs and losses
          reasonably incurred by ICI in so doing shall be promptly refunded by
          STIL to ICI.

          STIL's liability (whether in contract, negligence and/or tort) for
          default in the delivery of STIL Products shall be limited to the price

                                       24


          specified in Clause 8 times the amount of the STIL Products which STIL
          has failed to deliver due to its default under this Agreement.

     d)   If STIL shall default in taking the ICI Products, ICI shall be
          entitled to, and shall at STIL's request sell such products to a third
          party or third parties and, except as limited below, all additional
          costs and losses reasonably incurred by ICI in so doing shall be
          promptly refunded by STIL to ICI. STIL's liability (whether in
          contract, negligence and/or tort) for default in the taking of ICI
          Products shall be limited to the price specified in Clause 8 times the
          amount of the STIL Products which STIL has failed to take due to its
          default under this Agreement.

     e)   If ICI shall default in nominating or taking the STIL Products, STIL
          shall be entitled to and shall at ICI's request sell such products to
          a third party or third parties and except as limited below all
          additional costs and losses reasonably incurred by STIL in so doing
          shall be promptly refunded by ICI to STIL.
          ICI's liability (whether in contract, negligence and/or tort) for
          default in nominating and/or taking the STIL Products and for default
          in delivering the ICI Products shall be limited to the price specified
          in Clause 8 times the amount of the STIL Products which ICI has failed
          to nominate or take or the ICI Products which ICI has failed to
          deliver respectively due to its default under this Agreement.

     f)   If STIL shall supply any STIL Products that shall not meet the
          relevant specification described in Appendix 1, STIL shall promptly
          refund to ICI all costs and losses reasonably incurred by ICI arising
          therefrom provided that STIL's liability (whether in contract,
          negligence and/or tort) under this Paragraph f) shall be limited to
          the price specified in Clause 8 times the amount of the STIL Products
          which failed to meet the relevant specifications described in Appendix
          1.

     g)   If ICI shall supply any ICI Products that shall not meet the relevant
          specification described in Appendix 3, ICI shall promptly refund to
          STIL all costs and losses reasonably incurred by STIL arising
          therefrom provided that ICI's liability (whether in contract,
          negligence and/or tort) under this Paragraph g) shall be limited to
          the price specified in Clause 8 times the amount of the ICI Products
          which failed to meet the relevant specifications described in Appendix
          3.

                                       25


     h)   In all of the circumstances referred to in paragraph c) to g) above,
          each party shall be under a duty to take all reasonable steps to
          mitigate the costs and losses incurred by it.

     i)   Nothing contained in this Clause 17 shall have the effect of excluding
          either party's liability for death and personal injury caused by that
          party's negligence.

     j)   The parties acknowledge that damages may not represent an adequate
          remedy for a default on the part of either party to deliver products
          hereunder and that in the circumstances an order for specific
          performance may be an appropriate remedy.


 18. EXCLUSION OF WARRANTIES/PROVISION OF PRODUCT SAFETY DATA SHEETS

     a)   The product specifications herein constitute the whole of each party's
          obligations with respect to the quality of product to be supplied and
          (save to the extent that exclusion thereof is not permitted or is
          ineffective by operation of law) all statutory or other conditions or
          warranties, with respect to the description, merchantability or
          quality of the products or its fitness for any purpose are hereby
          excluded.

     b)   Notwithstanding the foregoing, each party shall, prior to first
          delivery of the product concerned, provide to the other party product
          safety data sheets relating to their respective products.


 19. DISCHARGE CONDITIONS AND DEMURRAGE

     a)   STIL has the right to deliver and ICI shall accept the delivery of the
          total quantity of STIL Products that STIL is entitled and/or obligated
          to deliver under this Agreement together with the amount of sediment
          and water as might be present in the tanks arising from the handling
          of the STIL Products by STIL and/or companies affiliated to STIL
          and/or the vessel operator acting always as a Reasonable and Prudent
          Operator. ICI shall not be obliged to accept delivery of STIL Products

                                       26


          under this Agreement if it has reasonable grounds to suppose that they
          contain a quantity of water and sediment in excess of such amount.

     b)   ICI shall accept discharge of the STIL Products at a berth which ICI
          shall provide or cause to be provided free of charge and which the
          vessel can safely reach and leave and at which such vessel can lie and
          discharge safely afloat. All charges at the discharge port (including
          berth shifting for backhauls of ICI Products), other than those
          defined by Worldscale as being for owner's account, shall be paid by
          ICI.

     c)   Unless otherwise agreed, for the purposes of this Agreement a full
          cargo shall be deemed to be the full carrying capacity of the vessel.
          The time allowed for discharging a full cargo shall be [+++++] Sundays
          and holidays included, and shall begin to run either:-

          (i)  six (6) hours after notice has been tendered by the Master or his
               representative to ICI, or their representative, of the vessel's
               readiness in all respects to discharge, berth or no berth, at any
               time of the night or day; or

          (ii) when the vessel is securely moored, whichever is earlier

     d)   Such notice of readiness may for the purposes of this Agreement be
          tendered at any time after the vessel has arrived within the customary
          anchorage or waiting place of the port of discharge or, if the vessel
          moves directly to the discharge berth, when the vessel is securely
          moored to the berth.

     e)   [+++++]

     f)   If the vessel is loading ICI Products, the time allowed for loading
          shall be [+++++] Sundays and holidays included, and shall begin to run
          either:

          (i)  If the vessel is discharging STIL Products, at the expiration of
               allowed discharge time as set forth in Clause 19 c) above; or

          (ii) if the vessel is not discharging STIL Products,
               a.   six (6) hours after notice has been tendered by the Master
                    or his representative to ICI, or their representative, of
                    the vessel's readiness in all respects to dis-

                                       27


                    charge, berth or no berth, at any time of the night or day;
                    or

               b.   when the vessel is securely moored, whichever is earlier.

     g)   If the vessel is not loading ICI Products, laytime shall cease on
          disconnection of cargo hoses on completion of discharging. If the
          vessel is loading ICI Products, laytime shall cease on disconnection
          of cargo hoses on completion of loading. Provided, however, that in
          either case, if the vessel is delayed after disconnection of cargo
          hoses for ICI's purposes in excess of one hour, laytime shall continue
          to run and demurrage, if incurred, shall continue to be payable from
          disconnection of cargo hoses until the termination of such delay.

     h)   Time shall not count against laytime, or if the vessel is on
          demurrage, for demurrage, when spent or lost:

          (i)   on an inward passage moving from her waiting place, even if
          lightening has occurred there, to the North Tees Works; or

          (ii)  whilst the vessel is handling or preparing to handle ballast or
          bunkers, unless this is carried out concurrent with discharging or
          other normal cargo operations such that no loss of time is involved,
          or is carried out to comply with shore restrictions; or

          (iii) by any delay due to fault, failure or inefficiency of the
          vessel, or if departure is delayed for vessel's purposes other than
          for reasons pertaining to safety of the vessel over which the vessel
          has no control, or

          (iv)  awaiting tide, tug boats, pilot, daylight or moderation of
          weather prior to berthing, ice, immigration, customs or pratique
          unless any or all of these delays are occasioned by shifting berth for
          ICI's account or unless any or all of these delays are the direct
          result of an initial delay or delays caused to the vessel for ICI's
          account.

          No other event shall suspend the running time to be counted as laytime
          or demurrage even if it is an event of a type described in Clause 20
          a).

                                       28


     i)   If the laytime allowance as provided for in this Clause 19 is exceeded
          ICI shall pay to STIL demurrage for all such excess time at the full
          rate specified below. ICI's liability for demurrage shall be absolute
          and shall not, in any case, be subject to the provisions of an
          exceptions or Force Majeure provision.

     j)   Unless otherwise agreed, the rate of demurrage to be used for the
          purposes of this Agreement shall be as follows:

          (i)    if the vessel is on voyage charter, the rate specified in the
          charterparty; or

          (ii)   if the vessel is not on a voyage charter, then the rate shall
          be the single voyage market level current in London on the date of
          commencement of loading of the voyage concerned for a vessel of
          similar type and summer deadweight to that actually involved. Such
          market level shall be agreed by ICI and STIL and shall be appropriate
          to the site of the vessel concerned. In default of agreement between
          ICI and STIL the market level is to be determined as the average rate
          advised by two independent brokers mutually acceptable to ICI and
          STIL. If ICI and STIL are unable to agree to two independent brokers
          then two such brokers shall be nominated by the Chairman for the time
          being of the London Tanker Brokers' Panel.

     k)   Payment of demurrage duty payable under this Agreement shall be made
          by ICI to STIL [+++++] of STIL's invoice (date of invoice equals day
          zero), and shall comply with the provisions of Clause 14.


 20. FORCE MAJEURE

     a)   If either party is by reason of Force Majeure rendered unable wholly
          or in part to carry out its obligations under this Agreement then (a)
          the party affected shall give notice in writing of such Force Majeure
          to the other party as soon as possible after the occurrence of the
          cause relied on and (b) the party affected shall be released from its
          obligations hereunder to the extent to which they are affected by the
          circumstances of Force Majeure and for the period during which those
          circumstances exist; provided that:

                                       29


          (i)   the party affected shall use all reasonable endeavors to
                terminate or mitigate the effect of the circumstances of Force
                Majeure with all reasonable speed,

          (ii)  nothing in this clause shall relieve either party of its
                obligations to make any payments due hereunder.

     b)   In this clause "Force Majeure" means circumstances beyond the control
          of the party concerned and which notwithstanding the exercise by it of
          reasonable diligence and foresight it was unable to prevent or
          overcome. In assessing the circumstances of Force Majeure the standard
          to be expected of a party shall be that of a Reasonable and Prudent
          Operator.

     For the avoidance of doubt:

          (i)    Force Majeure shall include the failure of a supplier to supply
                 STIL Products to STIL as a result of that suppliers' Force
                 Majeure provided, in such case, that STIL has used its
