                               Alumina Deliveries

     Section 3.1 Provision of Alumina Inventory for Basic Tonnage and Renewal
Tonnage.

          3.1.1 Beginning on the "Facility Commencement Date" under the Loan
Agreement Clarendon shall make Alumina Deliveries to NAC in the amounts and at
the times required to permit the full operation of Potline No. 2 (and, if
applicable under Section 3.2, to supply all the requirements for the full
operation of Potline No. 1) through September 30, 1989. The aggregate quantity
of Aluminum required to be produced from such Alumina Deliveries shall be
collectively called the "Basic Tonnage", which term shall include any Aluminum
expected to be delivered prior to September 30, 1989 at the time of the relevant
Alumina Delivery but which was delivered thereafter for whatever reason.

          3.1.2 Clarendon shall have the option to require NAC to Convert
Alumina into Aluminum for one or more additional periods, as provided more fully
in clauses M and (ii) of this Section 3.1.2, in which event Clarendon shall make
Alumina Deliveries to NAC in the amounts and at the times required to permit the
full operation of Potline No. 2 (and, if applicable under Section 3.2, to supply
all the requirements for Potline No. 1) for the periods in question. The
aggregate quantity of Aluminum required to be produced from such Alumina
Deliveries shall be collectively called the "Renewal Tonnage", which term shall
include any Aluminum which at the time of the relevant Alumina Delivery was
expected to be delivered prior to the end of the last period for which Clarendon
has exercised its option but which was delivered thereafter for whatever reason.

               (i) Clarendon shall have the option to require NAC to Convert
Alumina into Aluminum, as provided above in this Section 3.1.2, from October 1,
1989 through September 30, 1991 by giving written notice to NAC to that effect
on or prior to April 1, 1989.

               (ii) If Clarendon exercises the option described in clause M and
if the term of the Smelter Lease Agreement (as defined in the Loan Agreement) is
extended beyond September 30, 1991 by reason of a delay in the closing for NAC's
acquisition of the Smelter, Clarendon shall have the option to require NAC to
Convert Alumina into Aluminum, as provided above in this Section 3.1.2, from
October 1, 1991 through the date on which NAC acquires the Smelter by giving
written notice to NAC to that effect on or prior to July 1, 1991, provided that
Clarendon may terminate its obligation to make Alumina Deliveries after
September 30, 1991 upon at least three (3) months' prior notice to NAC.

          3.1.3 Scheduling of Alumina Deliveries shall be determined as follows:

               (i) Clarendon and NAC shall confer promptly upon execution of
this Agreement for the purpose of reaching mutual agreement as to the schedule
for Alumina

                                       5

Deliveries and the amount of Alumina inventory required at the Smelter during
the period ending December 31, 1987.

               (ii) Clarendon and NAC shall agree by no later than September 30
of each calendar year (starting September 30, 1987) on the schedule for Alumina
Deliveries and the amount of Alumina inventory required at the Smelter during
the following calendar year, without regard to Clarendon's possible exercise of
its rights under Section 3.1.2 or 3.2.

               (iii) Promptly upon Clarendon's exercise of its rights under
Section 3.1.2 with respect to Renewal Tonnage or under Section 3.2 with respect
to Alumina Deliveries for operation of Potline No. 1, Clarendon and NAC shall
confer for the purpose of reaching mutual agreement on amending the existing and
any prospective agreed-upon schedule for Alumina Deliveries to reflect the
changes required by Clarendon's exercise of such rights.

When determining the scheduling of Alumina Deliveries as required under clauses
(i) - (iii) above, the parties shall give due consideration of the capacity of
the Alumina storage facilities at the Smelter and the amount of Alumina required
to be kept on hand at all times to permit the full operation Potline No. 2 (and,
if applicable under Section 3.2, Potline No. 1) on an uninterrupted basis. The
parties shall use their best efforts to schedule Alumina Deliveries in
substantially equal quantities and as equally spaced as commercially reasonable.

          3.1.4 Clarendon shall make Alumina Deliveries in compliance with the
agreed-upon schedule then applicable under Section 3.1.3, subject to
modifications jointly agreed upon by NAC and Clarendon. If NAC incurs extra cost
by reason of Clarendon's failure to meet its Alumina Delivery obligation under
any agreed-upon schedule, subject to modification as provided above, Clarendon
shall pay to NAC an amount sufficient to compensate NAC for its excess costs so
incurred, provided that NAC shall keep complete records with respect to such
excess costs and shall provide Clarendon access to or copies of such records
promptly upon Clarendon's request.

          3.1.5 For purposes of this Section 3.1, "full operation" of a Potline
shall mean the operation permitting the production of Aluminum in the amounts
specified in Section 2.1.2.

     Section 3.2 Potline No. 1.

          3.2.1 Clarendon shall have the option, exercisable by notice to NAC,
to require NAC to operate Potline No. 1 on the condition that Clarendon provides
additional financing to NAC for the excess of (x) the amount determined by the
parties as being reasonably anticipated to cover NAC's startup costs and
increased working capital needs resulting from operating Potline No. 1, over (y)
any NAC funds on hand available for such purpose and the cash flow determined by
the parties as being reasonably anticipated to be generated by the operation of
Potline No. 1. If Clarendon exercises such option, NAC shall enter into a
financing arrangement with Clarendon for the net amount of required additional
financing under substantially the same terms as the Loan Agreement, and
thereafter Clarendon shall supply the

                                       6

Alumina requirements for operating Potline No. 1 and NAC shall Convert such
Alumina Deliveries and make Aluminum Deliveries as provided in Section 3.1.

          3.2.2 NAC may commence operating Potline No. 1 without the financial
assistance of Clarendon as specified in Section 3.2.1 and contract for the sale,
tolling or other arrangements regarding the product of Potline No. 1, provided
that NAC is fully performing its obligations under this Agreement with respect
to Potline No. 2, and its obligations under the Loan Agreement, at the time. If
NAC wishes to commence operating Potline No. 1 as provided above, NAC shall give
Clarendon notice to that effect not less than ninety (90) days prior to the
anticipated start-up date, which shall also be specified in its notice.
Clarendon shall have the option, exercisable by notice to NAC no later than
sixty (60) days prior to the anticipated start-up date specified in NAC's
notice, (a) to increase the Basic Tonnage by a quantity of Aluminum equal to the
output of Potline No. 1 during the period from such start-up until September 30,
1989, and/or (b) if NAC is at that time (or thereafter) required to Convert any
Renewal Tonnage under this Agreement, to increase the Renewal Tonnage by a
quantity of Aluminum equal to the output of Potline No. 1 during the period in
which NAC is required to Convert Renewal Tonnage. Upon Clarendon's exercise of
either of the above options, the quantity of Alumina to be delivered by
Clarendon shall be increased by the amount required to permit Conversion of the
increase in the Basic Tonnage and/or the Renewal Tonnage.

          3.2.3 If Potline No. 1 is restarted and Clarendon is obligated to
provide Alumina for its operation, the provisions of Section 4.2.1(ii) shall be
applicable with respect to Aluminum produced by Potline No. 1 during the first
five (5) months after Potline No. 1's start-up.

     Section 3.3 Alumina Specifications. The Alumina to be delivered under this
Agreement shall be metallurgical grade sandy alumina produced by Alcoa of
Australia, Worsley, Gove or QAL, conforming to the chemical and physical
specifications set forth in Schedules 1 and 2, respectively, unless otherwise
agreed in writing by NAC and Clarendon. The determination of chemical and
physical specifications at load-port shall be final, and NAC shall have the
right, at its own expense and upon at least thirty (30) days' prior notice to
Clarendon, to have its own representative present at such determination.

     Section 3.4 Conversion Ratio. NAC shall be obligated to deliver one (1)
Pound of Aluminum for each one and ninety-four hundredths (1.94) Pounds of
Alumina delivered by Clarendon for Conversion pursuant to this Agreement.
Similarly, the inventory of Alumina in NAC's custody shall be deemed to be
reduced, at the time of Aluminum Delivery, by one and ninety-four hundredths
(1.94) Pounds for each Pound of Aluminum delivered.

     Section 3.5 Weights. Subject to Section 3.7 in the event of split cargoes,
the weight of Alumina delivered under this Agreement shall be determined by
means of a draft survey taken upon loading, and such draft survey shall be
conclusive as to the loaded weight of Alumina. NAC shall have the right, at its
own expense and upon at least thirty (30) days' prior notice to Clarendon, to
have its own representative present at such determination.

                                       7

     Section 3.6 Transportation and Discharge Costs; Risk of Loss In Transit.

          3.6.1 All risk of loss to and costs of transporting Alumina to the
port for Alumina Delivery shall be borne by Clarendon (subject to Section
3.6-2), and NAC shall be responsible for the risk and costs of discharging the
Alumina from the vessel and transporting the Alumina to the Smelter and for all
other charges incurred after Alumina Delivery; provided that, with respect only
to Alumina for which Tolling Charges are to be calculated under Section 6.1.1
(including pursuant to Clarendon's election under Section 6.1.3), Clarendon
shall pay to NAC *** Dollars ($***) per Metric Ton of Alumina as its
contribution towards such costs to be paid by NAC.

          3.6.2 NAC shall designate, by at least sixty (60) days' prior notice
to Clarendon, the delivery port for each scheduled Alumina Delivery from among
the following ports: Portland, Oregon or Vancouver, Tacoma or Longview,
Washington; provided that NAC shall have the right to designate any other
reasonable U.S. West Coast port in its above notice to Clarendon and in such
event all excess transportation charges incurred by Clarendon as a result of the
Alumina Delivery at such other port shall be borne by NAC.

          3.6.3 NAC agrees to discharge Alumina from the delivering vessel at a
rate not less than six thousand (6,000) Metric Tons per Weather Working Day,
Sundays and Holidays Included ("WWDSHINC"). NAC shall indemnify and hold
Clarendon harmless from all losses, liability or expenses arising from any
failure to discharge Alumina at such rate.

     Section 3.7 Split Cargo. Clarendon shall give written advice to NAC if a
particular Alumina Delivery represents less than the total amount of alumina
loaded on the delivering vessel, and in such event the weight of the Alumina
Delivery for purposes of Section 3.5 shall be determined by multiplying (x) the
original bill of lading weight for the entire alumina cargo at the port of
loading, by (y) the percentage of such alumina cargo received by NAC as
determined on the basis of out-turn draft surveys at the time of unloading.

     Section 3.8 Notices of Delivery. Within one (1) working day after each
Alumina Delivery NAC shall give notice to Clarendon of NAC's receipt of the
Alumina, Delivery and shall thereupon, if requested by Clarendon, issue to the
order of Clarendon a warehouse receipt in form and substance satisfactory to

                             Aluminum; Releases and
                                Shipment; Storage

     Section 4.1 Aluminum Deliveries. NAC shall provide the Basic Tonnage and
(if applicable) the Renewal Tonnage to Clarendon by Aluminum Deliveries in
accordance with the releases given by Clarendon pursuant to Section 4.4.

                                       8

     Section 4.2 Aluminum Specifications.

          4.2.1 Subject to Sections 7.3.1(i) and 7.3.3(i), Aluminum delivered by
NAC under this Agreement as T-ingots or sows, or aluminum product used by NAC to
produce extrusion billets or sheet ingot as may be required by Clarendon under
Section 4.2.3, shall satisfy the following specifications:

               (i) unalloyed (Alcoa P1020) aluminum containing not less than
99.7% aluminum, and not more than 0.10% silicon and 0.20% iron, or

               (ii) to the extent that during the first five (5) months after
the restarting of Potline No. 2 NAC is unable to produce Aluminum meeting the
aluminum requirements of clause (i), NAC may deliver as "Aluminum" unalloyed
(Alcoa P1535) aluminum containing not less than 99.5% aluminum, provided that
NAC shall use its best efforts to minimize the amount of Aluminum containing
99.5% aluminum during such initial five-month period.

          4.2.3 Aluminum shall be at Clarendon's option in the form of sows or
T-ingots, or (at an additional charge as provided below) in the form of
extrusion billets or sheet ingot. Clarendon may require NAC to deliver T-ingots
or sows weighing less than the nominal standard of one thousand five hundred
(1,500) Pounds each. Clarendon will advise NAC of its shape requirements prior
to commencement of the month of Aluminum Delivery scheduled for such Aluminum.
If Clarendon elects to require that all or a portion of Aluminum to be delivered
in a particular month be in the form of extrusion billets or sheet ingot, then:

               (i) In addition to the Tolling Charge incurred under Section 6.1,
Clarendon shall reimburse NAC for the additional direct production costs
actually incurred by NAC in casting the extrusion billets or sheet ingot in
accordance with Clarendon's instructions. Such reimbursable costs shall be
adjusted to reflect due allowance for melt loss and additional alloying
components, and shall be reduced by the amount of the direct production costs
which would have been incurred by NAC had the relevant Aluminum been delivered
in the form of sows or T-ingots. Such reimbursable costs shall also include any
adjustments agreed to by the parties to reflect NAC's additional capital costs
incurred in order to produce such extrusion billets or sheet ingot (as provided
more fully below in this Section 4.2.3)

               (ii) In its invoice to Clarendon under Section 6.2 NAC shall
include an itemization of the additional production-related costs for casting
extrusion billets or sheet ingot and the cost savings referred to in clause (i).
NAC shall keep complete records with respect to such additional costs and cost
savings, and shall provide Clarendon access to or copies of such records
promptly upon Clarendon's request.

Nothing in this Section 4.2.3 shall entitle Clarendon to require NAC: to provide
Aluminum as extrusion billets or sheet ingot in a form which cannot be produced
using NAC's then existing facilities at the Smelter, and the parties shall
confer on the proper adjustment to the charges

                                       9

payable by Clarendon under clause (i) above if NAC incurs capital costs at
Clarendon's request to permit NAC to provide Aluminum in the requested form of
extrusion billets or sheet ingot.

     Section 4.3 Stored Aluminum. If Clarendon does not take immediate delivery
of any quantity of Aluminum, NAC will deliver such Aluminum into storage as
provided in Section 5.3, and upon such delivery into storage such Aluminum shall
constitute "Stored Aluminum" for purposes of this Agreement. Subject to release
by Clarendon pursuant to Section 4.4, NAC shall at its sole risk and expense
store Stored Aluminum, in the appropriate storage area pursuant to Section 5.3,
until the date of completion of Aluminum Delivery of the Basic Tonnage and (if
applicable) the Renewal Tonnage and during such additional period, not to exceed
twelve (12) months after the termination of this Agreement, as Clarendon shall
request.

     Section 4.4 Releases. Prior to the beginning of each calendar month
Clarendon shall give NAC a release for shipments of Aluminum Deliveries to be
made in such calendar month containing the following information:

          (i) MT of each lot (minimum of 40,000 Pounds if shipped by truck and
100,000 Pounds if shipped by rail);

          (ii) Delivery date; and

          (iii) Shipping instructions.

If no releases are given, the Aluminum shall be treated as Stored Aluminum, and
Clarendon shall deliver releases containing similar information regarding
shipments of Stored Aluminum at least ten (10) days prior to shipment.

     Section 4.5 Loading Costs; Shipment Arrangements and Costs. NAC shall bear
all costs relating to loading the Aluminum on board the carrier at the Smelter.
NAC will arrange for shipment of Aluminum by the most economical available means
of transportation from the Smelter to the Destination Plant, all in accordance
with the releases given by Clarendon pursuant to Section 4.4. If Clarendon so
requests, NAC shall prepay shipping costs for the account of Clarendon and send
Clarendon invoices for such amount together with copies of the documents
evidencing the invoiced amount, and Clarendon shall reimburse NAC promptly after
its receipt of NAC's invoice and accompanying documentation.

     Section 4.6 Transfer of Risk of Loss. Risk of loss to any Aluminum shall
pass to Clarendon upon delivery of such Aluminum to the carrier at the Smelter
in accordance with Clarendon's release given pursuant to Section 4.4.

                         NAC's Bailment Responsibilities

     Section 5.1 All Title and Rights of Ownership Retained by Clarendon.

          5.1.1 NAC acknowledges and agrees that by the execution of this
Agreement it does not have nor will it obtain, and by its performance under this
Agreement it does not and will not have or obtain, any title to the Bailed
Property or any property right or interest, legal or equitable, therein, except
for its right to possession for purpose of transportation, storage and
Conversion as provided in this Agreement.

          5.1.2 All Alumina delivered by Clarendon under this Agreement shall be
considered to have been delivered for Conversion only. No Alumina or Aluminum
shall be bought or sold hereunder, except as the parties may mutually agree in
writing. No Alumina shall be redelivered as Alumina except in the event this
Agreement is terminated pursuant to Article 10.

     Section 5.2 Prohibition Against NAC's Liens. NAC shall not at any time
directly or indirectly assert for its benefit, or create, incur, assume or
suffer to exist for the benefit of any creditor, any Lien on or with respect to
any Bailed Property, title thereto or any interest therein. NAC shall promptly,
at its own expense, take such action as may be necessary duly to discharge any
such Lien.

     Section 5.3 Segregated Storage; Notices and Markings; Inventory Records.
NAC, at its own expense, will:

          5.3.1 Segregate and store all Alumina prior to using the same for
Conversion, and segregate and store all Stored Aluminum, in fenced or otherwise
contained facilities at the Smelter which are separate from those used for
warehousing materials or products owned by NAC or others, and shall cause to be
conspicuously affixed and displayed on each such facility notices containing the
following language in letters not less than two inches in height:

          "This property is owned by Clarendon Ltd. and held by Northwest
          Aluminum Company pursuant to an Aluminum Toll Conversion Agreement
          between Clarendon Ltd. and Northwest Aluminum Company dated September
          15, 1986 and subject to the provisions thereof, and is also subject to
          a security interest granted by Clarendon Ltd. under a [Loan Agreement)
          between Clarendon Ltd. and [Secured Party]. Any sale, hypothecation or
          other encum brance of this property is in violation of said Aluminum
          Toll Conversion Agreement and [(Loan Agreement]."

                                       11

NAC shall not permit the removal or concealment of any of the above-required
notices.

          5.3.2 Mark all Aluminum (in any of its forms) with a distinctive mark
acceptable to Clarendon which shall be sufficient to identify such Aluminum as
being owned by Clarendon and subject to this Agreement.

     Section 5.4 NAC's Liability for Loss, etc. NAC shall replace, at its own
expense, any Bailed Property which suffers any damage, loss, theft or
destruction, partial or complete, from whatever cause while in the possession of
NAC. Such replacement Bailed Property shall meet the specifications required
under this Agreement, and shall constitute accessions to the Bailed Property and
title thereto shall vest and remain in Clarendon. NAC shall maintain normal
general comprehensive insurance (in form and substance satisfactory to
Clarendon) to protect against such occurrences, and Clarendon shall be an
additional insured and loss payee with coverage equal to at least one hundred
twenty percent (120%) of the average anticipated value of the Bailed Property
over the then current twelve-month period ending on an anniversary of July 1,
1986. Each such insurance policy shall provide that Clarendon shall be given at
least thirty (30) day's prior written notice of termination for whatever reason.

     Section 5.5 Inventory Records. NAC shall maintain an accurate, detailed and
current inventory of all Bailed Property clearly identifying the Bailed Property
as the property of Clarendon, separately from all inventory and other records
for materials, products or other property owned by NAC or others, and shall
submit to Clarendon at all reasonable times upon Clarendon's request and in any
event within the first five (5) days of each calendar month an accurate and
detailed inventory of all Bailed Property as at the last day of the immediately
preceding calendar month or shorter inventory period. Clarendon shall have the
right, exercisable directly or through its regular certified accountants or
other representatives, to verify each such inventory of Bailed Property at any
time during the Smelter's ordinary business office hours at Clarendon's
discretion upon five (5) hours' notice.

     Section 5.6 Taxes. Clarendon shall bear all property taxes and import
duties on the Bailed Property, now imposed or hereafter becoming effective
within the term of this Agreement, and all federal, state or local taxes on
corporate income or sales taxes incurred by Clarendon in connection with the
sale of Aluminum to its customers, now imposed or hereafter becoming effective
within the term of this Agreement. Clarendon shall not be liable for any other
governmental taxes, charges or imposts, including, without limiting the
generality of the foregoing, any federal, state or local taxes on corporate
income incurred by NAC with respect to the Tolling Charges.

                         Tolling Charges; Payment Terms

     Section 6.1 Calculation of Tolling Charges. The Tolling Charges payable
hereunder shall be calculated as follows:

                                       12

          6.1.1 For Aluminum Deliveries made during the period ending on
December 31, 1987, Clarendon shall pay a Tolling Charge per Pound of Aluminum
delivered calculated in accordance with Schedule 3.

          6.1.2 For Aluminum Deliveries with respect to the remainder of the
Basic Tonnage and any Renewal Tonnage, Clarendon shall pay a Tolling Charge in
Dollars per Pound of Aluminum equal to the greater of:

               (i) *** (***%) of the "Aluminum Metal defined in Section 6.1.4)
applicable for the third calendar month immediately preceding the calendar month
in which the Aluminum Delivery occurs, as more fully provided in Section 6.1.4,
or

               (ii) the "Actual Production Costs" (as defined in Section 6.1.5)
for the third calendar month immediately preceding the calendar month in which
the Aluminum Delivery occurs, up to a maximum of $*** per Pound.

          6.1.3 Notwithstanding the foregoing: (i) if for any reason (including
without limitation Force Majeure) the aggregate quantity of Aluminum Deliveries
during the period ending on December 31, 1987 is less than fifty-five thousand
(55,000) Metric Tons, Clarendon shall have the option of paying, with respect to
any of the first Aluminum Deliveries after December 31, 1987 up to the amount of
any such deficiency, a Tolling Charge per Pound of Aluminum based on the method
of calculation set forth in either Section 6.1.1 or Section 6.1.2.; and (ii)
except as provided in W above, if any Aluminum Delivery scheduled to be made in
a calendar quarter is made in a later calendar quarter by reason of the
occurrence of a Force Majeure, the Tolling Charge applicable to such Aluminum
Delivery, when made, shall be the Tolling Charge which would have applied if the
Force Majeure had not occurred.

          6.1.4 For purposes of this Section 6.1, "Aluminum Metal Price" means
the arithmetic average of the lesser, on each day, of (a) the settlement price
of aluminum on the London Metal Exchange ("LME") or (b) the three month seller's
price of aluminum on the LME, in each case as published in "Metal Bulletin" as
the seller's price under the caption "Daily Metal" for the third calendar month
immediately preceding the calendar month of Aluminum Delivery, subject to the
following conditions:

               (i) LME settlement prices shall be converted to U.S. Dollars
using the mid point of the spot Sterling Pound/Dollar exchange rate published in
Metal Bulletin for the relevant day under the caption "MB/Chase Manhattan Forex
Quotations (1400 hours)", and LME three month seller's prices shall be converted
to U.S. Dollars using the mid point of the three month forward Sterling
Pound/Dollar exchange rate published in the Metal Bulletin for the relevant day
under the same caption.

               (ii) The parties agree that the LME reference prices described in
clause (i) are the basis upon which a value of aluminum ingot in major free
world markets can be established. If a significant change occurs in the LME
reference prices' historic relationship

                                       13

to free world values, and such change is for a duration of nine months or
longer, the parties agree, upon the request of either of them, to meet to
discuss in good faith an alternative basis for establishing such value.

               (iii) If the LME at any time publishes only one of the two
reference prices specified in clause (i), the published reference price shall be
used to calculate the "Aluminum Metal Price". If the LME ceases to trade
aluminum or ceases to publish both of such reference prices, the "Aluminum Metal
Price" shall mean the generally accepted substitute for LME reference prices. If
there is no such generally accepted substitute, the parties in good faith shall
select a substitute. Failing such agreement, "Aluminum Metal Price" shall mean
the arithmetic average of the prices of aluminum on the COMEX as published in
Metals Week under the caption "COMEX 1ST POS." during the period set forth at
the beginning of this Section 6.1.4.

          6.1.5 For purposes of this Section 6.1, "Actual Production Costs"
shall mean the actual cash cost to NAC, in U.S. Dollars per Pound, of Converting
Aluminum during the third calendar month immediately preceding the calendar
month of Aluminum Delivery, including the cost of all materials, electricity and
labor and all Smelter lease rent expenses, normal relining expenses, general and
administrative costs and net interest expenses, but excluding depreciation and
amortization of organization costs, as computed in accordance with generally
accepted accounting principles.

     Section 6.2 Invoicing. The Tolling Charge for Aluminum produced and
available for shipping shall be invoiced after the time of Aluminum Delivery,
and not more frequently than once per calendar week. Each invoice for Tolling
Charges shall include an itemization of any additional charges payable by
Clarendon under Section 3.6.1 or 4.2.3, shall reflect any credits to Clarendon
under Section 3.6.2 as specified by Clarendon's notice thereof to NAC or any
adjustment agreed to by the parties under Section 7.3.1(i), and shall be
accompanied by a certificate of Aluminum, quality and quantity for the Aluminum
Deliveries concerned in form and substance acceptable to Clarendon.

     Section 6.3 Payment Terms. Each of NAC's invoices shall be payable in
Dollars in immediately available funds ten (10) days after Clarendon's receipt
of such invoice, provided that if the payment date is a Saturday, Sunday or day
on which banks in Oregon or New York are authorized or required to close,
payment shall be due on the next day which does not constitute any of the
foregoing. Each payment shall be provisional and subject to Clarendon's right to
audit and challenge NAC's determination of quality and quantity or calculation
of amounts payable.

                                       14

                                    Article 7

                         Warranties; Indemnity; Remedies

     Section 7.1 Specifications Warranty. NAC warrants that all Aluminum
tendered for Aluminum Delivery under this Agreement shall conform to the
specifications set forth in Section 4.2.1 unless otherwise agreed under Section
7.3, and shall be free from defects in material and workmanship. Clarendon
warrants that the Alumina it delivers to NAC for Conversion hereunder shall
conform to the specifications set forth herein.

     Section 7.2 Non-Conforming Alumina. If the chemical or physical
specifications determined under Section 3.3 reveal that any Alumina does not
conform to the specifications set forth in this Agreement, or if any Alumina has
been or is believed to have been contaminated after loading, the party
discovering such non-conformity or known or suspected contamination shall give
prompt notice thereof to the other party, and NAC and Clarendon shall
immediately consult and shall make such adjustments as they may agree to be
appropriate.

     Section 7.3 Remedy for Non-Conforming Aluminum.

          7.3.1 If any chemical analysis report delivered by NAC under Section
4.2.2 indicates that the material in question does not satisfy the
specifications for Aluminum under Section 4.2.1, or such material otherwise
fails to meet the requirements set forth in this Agreement, NAC shall give
notice to Clarendon to that effect and shall not make the related Aluminum
Delivery but shall store the nonconforming material separate from Stored
Aluminum. NAC and Clarendon shall promptly confer on whether the payment of an
adjustment amount reflecting the decreased market value of the non-conforming
material is adequate compensation to Clarendon in light of the circumstances
(including without limitation the needs of Clarendon's customer for conforming
material).

               (i) If an adjustment is agreed to by the parties within fifteen
(15) days after Clarendon's receipt of NAC's notice, the non-conforming material
shall be deemed "Aluminum" and "Bailed Property" for purposes of this Agreement,
and the amount of such adjustment shall be reflected in NAC's invoice for such
Aluminum Delivery. If Clarendon has paid the Tolling Charges for the Aluminum
Delivery without adjustment, Clarendon shall invoice NAC f or the amount of the
adjustment and NAC shall pay the invoiced amount within ten (10) days after
receipt of Clarendon's invoice.

               (ii) If an adjustment is not agreed to within fifteen (15) days
after Clarendon's receipt of NAC's notice:

                    (a) NAC shall, at its own expense, purchase conforming
aluminum and deliver the same to Clarendon at the Smelter (or, at Clarendon's
request, to a Destination Plant) within a maximum period of forty-five (45) days
after the date of NAC's notice; provided that NAC shall use its best efforts
with due regard to the circumstances to effect

                                       15

such replacement within as short a period as possible. Any aluminum purchased by
NAC for delivery to Clarendon under the preceding sentence shall be deemed to be
"Aluminum" and "Bailed Property" immediately upon NAC's purchase, and title
thereto shall pass to Clarendon immediately upon NAC's purchase. Clarendon's
liability to reimburse NAC for the cost of shipping the replacement material to
a Distribution Plant shall be the lesser of W the actual shipping costs incurred
by NAC for such delivery, or (y) the costs which could have been incurred for a
shipment from the Smelter in the usual course, assuming the original material
had conformed to the required specifications.

                    (b) Upon the expiration of the fifteen (15) day period, NAC
shall be relieved of all risk and liability to Clarendon with respect to such
non-conforming aluminum (which shall cease to be "Aluminum" and "Bailed
Property" for purposes of this Agreement), and title thereto shall immediately
pass to NAC.

          7.3.2 Clarendon or its representatives or customers may inspect
Aluminum after arrival at the Destination Plant. Clarendon will be deemed to
have accepted the Aluminum if Clarendon fails to give NAC written notice of
rejection within sixty (60) days after such arrival, which notice shall describe
the defects causing rejection. NAC shall have the right, at its own expense, to
inspect the rejected material within fifteen (15) days after the date of Claren
don's notice of rejection.

          7.3.3 If Aluminum is rejected as provided in Section 7.3.2, NAC and
Clarendon shall promptly confer on whether the payment of an adjustment amount
reflecting the decreased market value of the rejected material is adequate
compensation to Clarendon in light of the circumstances (including without
limitation the needs of Clarendon's customer for conforming material).

               (i) If an adjustment is agreed to by the parties within fifteen
(15) days after Clarendon's notice of rejection, the non-conforming shall
continue to be deemed "Aluminum" for purposes of this Agreement, and Clarendon
shall invoice NAC for the amount of the adjustment. NAC shall pay the invoiced
amount within ten (10) days after receipt of such invoice.

               (ii) If an adjustment is not agreed to within fifteen (15) days
after Clarendon's notice of rejection:

                    (a) NAC shall, at its own expense, purchase conforming
aluminum and deliver the same to Clarendon at the Destination Plant within a
maximum period of forty-five (45) days after the date of Clarendon's notice of
rejection; provided that NAC shall use its best efforts with due regard to the
circumstances to effect such replacement within as short a period as possible.
Any aluminum purchased by NAC for delivery to Clarendon under the preceding
sentence shall be deemed to be "Aluminum" and "Bailed Property" immediately upon
NAC's purchase, and title thereto shall pass to Clarendon upon NAC's purchase.

                                       16

                    (b) The rejected aluminum shall immediately cease to be
deemed "Aluminum" for purposes of this Agreement, and Clarendon shall arrange
and facilitate the shipment of the rejected aluminum to NAC - Clarendon's duty
of care with respect to the rejected aluminum while in its custody shall be that
of ordinary diligence. Clarendon shall be relieved of all risk and liability
with respect to such rejected aluminum, and title thereto shall pass to NAC,
immediately upon Clarendon's delivery thereof to the carrier for return to NAC.
NAC shall reimburse Clarendon, within ten (10) days after Clarendon's request
from time to time, for all costs which Clarendon may reasonably incur in
connection with the unloading, load ing, storage, handling and/or shipping of
the rejected aluminum.

     Section 7.4 Remedy for Yield Short-fall. If the yield of Aluminum from the
Alumina does not equal or exceed one Pound of Aluminum for every one and
ninety-four hundredths (1.94) Pounds of Alumina delivered under Alumina
Deliveries, NAC shall promptly, at its own expense, purchase and deliver to
Clarendon at the Smelter, in the same manner as applicable for Aluminum
Deliveries, conforming aluminum sufficient to make up such yield short-fall. Any
aluminum purchased by NAC for delivery to Clarendon under the preceding sentence
shall be deemed to be "Aluminum" and "Bailed Property" immediately upon NAC's
purchase, and title thereto shall pass to Clarendon upon NAC's purchase.

     Section 7.5 Indemnity Regarding NAC's Operation of Smelter. NAC hereby
agrees to indemnify Clarendon, its successors and assigns and its and their
shareholders, directors, officers, employees, agents and customers
(collectively, the "Indemnitees") against, and agrees to protect, save and keep
harmless each Indemnitee from, any and all liabilities, obligations, losses,
damages, claims (including without limitation claims based on warranty, breach
of contract, negligence or strict liability in tort), penalties, actions, suits,
costs, expenses and disbursements (including without limitation legal fees and
expenses) of whatsoever kind and nature, imposed on, incurred by or asserted
against any Indemnitee in any way relating to or arising out of any of the
matters described in Sections 2.2.2 or 2.2.3.

     Section 7.6 Incidental Damages, etc. Except with respect to the indemnity
obligations of NAC under Section 7.5, no party shall be responsible for any
incidental, special or consequential damages suffered by another party arising
from a breach of this Agreement.

                                    Article 8

                                  Force Majeure

     Section 8.1 Force Majeure. The following shall constitute "Force Majeure"
for purposes of this Agreement:

          8.1.1 Any act of God or the public enemy, fire, explosion, perils of
the sea, flood, drought, war, riot, sabotage or embargo, and any interruption of
or delay in transportation, any inadequacy or shortage or failure of supply of
raw materials or equipment, and any breakdowns resulting from any of the
foregoing;

                                       17

          8.1.2 Any labor trouble from whatever cause arising and whether or not
the demands of the employees involved are reasonable and within the affected
party's power to concede;

          8.1.3 Compliance with any order, action, direction or request of any
Regulatory Authority or with any other Applicable Laws; or

          8.1.4 Without limiting the foregoing circumstances, any circumstance
of like or different character beyond the reasonable control of the affected
party.

     Section 8.2 Effect of Force Majeure. If any party is prevented from, or
delayed in, performing any obligation on its part under this Agreement by reason
of Force Majeure, the party so affected shall, upon prompt written notice to the
other party in advance of actual shipments, be excused from making or taking
deliveries to the extent and for the duration of the period that the same is
prevented by reason of Force Majeure. In that event, at the option of Clarendon
by notice to NAC, the total quantity of Alumina to be delivered by Clarendon to
NAC may be reduced by the quantity of Alumina so affected, or the delivery of
the Alumina so affected may be deferred and the dates used for determining Basic
Tonnage and Renewal Tonnage may be extended for the duration of such period;
provided that in all events Clarendon shall have the right to take possession of
any Alumina which cannot timely be Converted by reason of Force Majeure.

     Section 8.3 Notices Regarding Force Majeure. If a party's performance is
affected, or may be affected, by Force Majeure, such party shall give notice
thereof to the other party within seven (7) days after the occurrence of such
Force Majeure, which notice shall include, insofar as known, a statement of the
probable extent to which the affected party will be unable to perform or will be
delayed in performing its obligations hereunder. Each party shall exercise due
diligence to eliminate or remedy any such Force Majeure and to prevent the same
from un necessarily delaying and interrupting its performance hereunder, and
shall give the other party prompt written notice when such Force Majeure shall
have been eliminated or remedied.

the rights or obligations of NAC or Clarendon (for purposes of this Section

transferred, prior to the effectiveness of such assignment or other transfer,
NAC or Clarendon, whichever is not the affected party (for purposes of this
Section 12.2, the "non-affected party") shall be furnished with adequate

ability of any proposed assignee or transferee to perform the affected party's
duties or obligations under this Agreement.

enter into this Agreement in part by the other's financial ability, credit

     Section 13.1 General Provisions. All disputes arising under or by virtue of
this Agreement or concerning any difference of opinion between the parties
hereto concerning their rights and obligations under this Agreement shall be
referred to and determined exclusively by arbitration as provided in this
Article 13; provided, however, that arbitration shall not be invoked with
respect to or be determinative as to:

                                     22

          13.1.1 any claim or demand by Clarendon for indemnification under
Section 7.5,

          13.1.2 any claim or demand by Clarendon in the event NAC fails to
deliver any Aluminum otherwise available for delivery to Clarendon, or (if
applicable) the Bailed Property, as required under this Agreement,

          13.1.3 any claim or demand by Clarendon in connection with NAC's
breach of any of its undertakings under Article 5,

          13.1.4 any claim or demand arising in any litigation or proceeding

to this Agreement is an indispensable party or third party defendant, and

          13.1.5 any claim or demand arising in any litigation or proceeding
commenced by one party to this Agreement against the other in which a third
party is an indispensible party.

Any issue required under this Agreement to be arbitrated shall be submitted to
arbitration in the City of New York in accordance with the Commercial
Arbitration Rules of the American Arbi tration Association then in effect. Such
arbitration shall be conducted by proceedings held in New York City by an
arbitration panel whose members are chosen in the manner provided in Section
13.2 (the "Arbitration Panel"), and the proceedings of the Arbitration Panel
shall be conducted in the manner provided in Section 13.3.

     Section 13.2 Initial Identification of Questions for Arbitration; Selection
of Arbitration Panel. Arbitration may be invoked by either party (the
"Complaining Party") by written notice to the American Arbitration Association
and the other party (the "Respondent"), which notice shall state the name of the
arbitrator appointed by the Complaining Party and shall also state specifically
the question or questions as to which the Complaining Party is demanding
arbitration, the amount claimed, if any, and the relief sought. Notwithstanding
anything to the contrary which may now or hereafter be contained in the rules of
the American Arbitration Association, the selection of the members of the
Arbitration Panel, and the initial identification of the question or questions
to be resolved by the Arbitration Panel, shall take place in the following
manner:

          13.2.1 By notice to the Complaining Party given within twenty (20)
days after receipt of the Complaining Party's demand, the Respondent shall
appoint a second arbitrator and, if it desires, specify in its notice any
additional questions it wishes to have resolved by the Arbitration Panel,
provided that

               (i) The Respondent shall have the right to request one (1)
extension of such twenty (20) day period (not to exceed an additional twenty
(20) days) for its notice, provided such request is given by the Complaining
Party within the twenty (20) day period specified in the first sentence of this
Section 13.2-1.

                                       23

               (ii) If the Respondent fails to give timely notice of appointment
of a second arbitrator, the Respondent shall be deemed to have appointed as its
own arbitrator the arbitrator previously appointed by the Complaining Party and
arbitration shall proceed before the sole arbitrator who alone shall constitute
the Arbitration Panel.

               (iii) If the Respondent fails to give timely notice of additional
questions to be resolved by the Arbitration Panel, the Arbitration Panel shall
consider the questions specified in the Complaining Party's notice pending
submission of any additional questions for resolution by the Arbitration Panel
under Section 13.5.

          13.2.2 If two arbitrators are appointed in the manner specified in
Section 13.2.1, they shall thereupon select a third arbitrator by notice to each
of the Complaining Party and the Respondent in the manner specified in Section
14.5; provided that if the two arbitrators appointed by the parties are unable
to agree as to the third arbitrator within twenty (20) days from the date on
which the Complaining Party received notice from the Respondent of the
appointment of the second arbitrator, the third arbitrator shall be appointed by
the New York Regional Director of the American Arbitration Association upon
application by the Complaining Party. The three arbitrators so named shall
constitute the Arbitration Panel for the settlement of the questions specified
in the Complaining Party's demand for arbitration and (if applicable) the
additional questions specified in the Respondent's notice and such other
questions permitted under Section 13.5.

          13.2.3 If the Arbitration Panel consists of three arbitrators, the
third arbitrator selected in the manner set forth in Section 13.2.2 shall act as
chairman of the Arbitration Panel, and all procedural issues shall be determined
by majority vote.

          13.2.4 Each arbitrator shall be impartial, and no event shall an
individual be appointed or act as an arbitrator who is in any way interested
financially in this Agreement or in the business affairs of either party to this
Agreement.

     Section 13.3 Arbitration Procedure; Decisions. The proceedings of the
Arbitration Panel shall be conducted in accordance with the Commercial
Arbitration Rules of the American Arbitration Association then in effect,
subject to the following conditions:

          13.3.1 Either party may submit any evidence on any question properly
presented to the Arbitration Panel, and may be represented by counsel at all
times during the proceedings if desired. The Arbitration Panel shall be entitled
to consider all documents, papers, testimony or other evidence which the parties
shall offer for submission, even though not otherwise admissible as evidence in
a court of law in the State of New York or any other jurisdiction.

          13.3.2 The Arbitration Panel shall be authorized to permit discovery,
pursuant to the provisions of the Federal Rules of Civil Procedure, if a
majority of the arbitrators deem such discovery to be appropriate in the
circumstances.

                                       24

          13.3.3 The Arbitration Panel shall be bound by the terms of Section
14.3 in interpreting the terms and conditions of this Agreement and the rights
and obligations of the parties hereunder, and shall be bound by any prior
determinations made by other Arbitration Panels appointed under this Article 13.
In no event shall the Arbitration Panel have the authority, by reason of this
Agreement or otherwise, to render a decision which is contrary to the express
intent of the parties as expressed in this Agreement.

          13.3.4 The Arbitration Panel's decisions as to matters in dispute, and
its awards of damages and expenses under Section 13.4, shall be made by the sole
arbitrator or by the majority of the three arbitrators constituting the
Arbitration Panel, as the case may be, on the basis of a written opinion
delivered to both parties which shall set forth the Arbitration Panel's findings
of fact and conclusions of law, and include any dissenting opinion by an
arbitrator. Either party shall have the right, within ten (10) days after
receipt of the Arbitration Panel's decision, to file a motion to reconsider, and
the Arbitration Panel shall thereupon reconsider the issues raised in that
motion and either confirm or change the written opinion previously delivered in
a writing delivered to each of the parties. The cost of such a motion for
reconsideration and any new written opinion by the Arbitration Panel shall be
borne by the moving party.

          13.3.5 Each decision and award as to any questions submitted to the
Arbitration Panel shall be final, binding and conclusive upon the parties and
their respective successors and assigns. Each party agrees to abide by each of
such decisions and awards and further agrees that judgment may be entered upon
any decision and award made hereunder in any court of competent jurisdiction.

          13.3.6 The Arbitration Panel shall be empowered to issue final
decisions and awards as to particular questions to be resolved in the
proceeding, notwithstanding the pendency of other questions requiring
resolution, and to grant such relief under legal and equitable principles,
including interim or preliminary relief, as it deems appropriate.

     Section 13.4 Costs of Arbitration. In the written document settling forth
its decision and award, the Arbitration Panel shall determine which party shall
bear the fees and expenses of the arbitration (including without limitation the
fees of the arbitrators, and administrative expenses) and attorneys' fees
incurred by both parties, or the proportion or amounts of such fees and expenses
which each party shall bear. Notwithstanding the foregoing, each party shall
bear the expense of presenting its own witnesses and evidence to the Arbitration
Panel.

     Section 13.5 Additional Questions; Limitation on Multiple Arbitrations. It
is the parties' intent that all questions in dispute during the pendency of an
arbitration proceeding under this Article 13 be resolved by the Arbitration
Panel selected for such proceeding. In furtherance of such intent, the parties
hereto agree as follows:

          13.5.1 After the initial identification by the parties of the
questions to be resolved under Section 13.2, the Arbitration Panel shall permit
each party to propose additional questions for resolution in the pending
proceeding.

                                       25

          13.5.2 During the pendency of any arbitration proceeding no separate
arbitration proceeding shall be initiated by either party, unless the other
party agrees in writing or the Arbitration Panel in the pending proceeding has
issued a written determination, by vote in accordance with the terms of Section
13-3.3, that the questions proposed for resolution by arbitration can be more
expeditiously and economically resolved in a separate proceeding.

          13.5.3 Any Arbitration Panel organized to consider an arbitrable
question during the pendency of another arbitration proceeding shall be required
as its first order of business to determine whether the terms of this Section
13.5 have been satisfied, and it shall have the discretion to suspend the
proceeding for which it was appointed until final resolution of the questions
submitted in the pending proceeding if such Arbitration Panel determines, by
vote in accordance with the terms of Section 13.3.3, that the results of the
pending proceeding will be germane to the questions presented at the new
proceeding under principles of collateral estoppel.

                                   Article 14

                            Miscellaneous Provisions

     Section 14.1 Entire Agreement; Amendment. This Agreement constitutes the
entire agreement of the parties hereto with respect to the subject matter hereof
and supersedes any prior expressions of intent or understandings with respect to
such subject matter. This Agreement may only be amended, modified, supplemented
or released by an instrument in writing signed by a duly authorized officer of
each of the parties.

     Section 14.2 Waiver; Cumulative Rights. The failure or delay of either
party to require performance by the other of any provision of this Agreement
shall not affect such party's right to require performance of that provision
unless and until performance has been waived in writing. Each and every right
granted under this Agreement or any other document or instrument delivered
hereunder or in connection herewith, or allowed at law or in equity, shall be
cumulative and may be exercised in part or in whole from time to time.

     Section 14.3 Governing Law; Headings. This Agreement shall in all respects
be governed by, and construed in accordance with, the laws of the State of New

not limit or otherwise affect the scope or interpretation of any provision.

     Section 14.4 Consent to Jurisdiction; Service of Process.

          14.4.1 Each party irrevocably agrees that any legal action or
proceeding against it or any of its property (i) for the enforcement of any
arbitration decision under Article 13, and (ii) with respect to those matters
arising out of or with respect to this Agreement for which arbitration is not
required under Section 13.1, may be brought in any jurisdiction where assets of
that party may be found, or in any federal or state court located in the city of
New York, or

                                       26

in two or more of such places, as the other party may elect. By execution and
delivery of this Agreement each party accepts with regard to any such action or
proceeding for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts and waives any defense
it may have as to improper venue or that any of the above courts is an
inconvenient forum.

its behalf service of process in the State of New York in any legal action or

upon delivery thereof to said agent, it is understood that a copy of any such
process served on such an agent shall be promptly forwarded by the person
commencing such proceeding to NAC at its address set forth in Section 14.5, but
the failure of NAC to receive the copy shall not affect in any way the service
of such process as aforesaid. NAC shall at all times maintain an agent to
receive service of process in the State of New York on behalf of itself and its
properties with respect to this Agreement, and if, for any reason, the agent
named above or any successor shall no longer serve as agent on its behalf, NAC
shall promptly appoint a successor and give notice to Clarendon of the

any of the aforementioned courts in any such action or proceeding by the mailing
of copies thereof by registered or certified air mail, postage prepaid, to NAC
at its address set forth in Section 14.5, such service to become effective upon
receipt by NAC. Nothing herein shall affect the right of Clarendon to serve
process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against NAC in any other jurisdiction.

of any jurisdiction to commence any legal action or proceeding with respect to
this Agreement by publi cation.

         Subject to the following conditions:

          (1) For purposes of this rate schedule, the "Monthly Billing Aluminum
Price" shall mean the average price of aluminum in U.S. markets during the third
calendar month prior to the month of Aluminum Delivery. For purposes of this
calculation, the average price of aluminum in U.S. markets shall be the average
U.S. Transaction Price reported for the month by Metals Week, in cents per
Pound, rounded to the nearest one-tenth of a cent.

          (2) If the Monthly Billing Aluminum Price applicable for Aluminum
Deliveries during any calendar month is greater than 53.2(cent) and less than
79.333(cent) and is not equal to a column (B) price, the Tolling Charge to be
applicable for Aluminum Deliveries during that calendar month shall be prorated,
if necessary, to the nearest one-thousandth of one cent. Such proration shall be
based on the actual Monthly Billing Aluminum Price (as determined under clause
(1) above) and the Tolling Charges indicated opposite the column (B) prices
which constitute the price range under this rate schedule which includes the
actual Monthly Billing Aluminum Price.

          For example: If the Monthly Billing Aluminum Price is 57.3(cent), the
          Tolling Charge will be
