AGREEMENT TO TOLL CONVERT ALUMINA INTO ALUMINUM (TOLLING CONTRACT) CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT ASTERISKS (*) DENOTE SUCH OMISSIONS The parties to this agreement to toll convert alumina into aluminum are: 1. HYDRO ALUMINUM LOUISVILLE, INC., a Delaware corporation ("Hydro") and 2. GOLDENDALE ALUMINUM COMPANY, a Delaware corporation, formerly known as Columbia Aluminum Corporation (the "Company"). This is an Agreement by Hydro to supply alumina for toll conversion by the Company into standard aluminum ingot and related products as specified by Hydro at the Company's aluminum smelter near Goldendale, Washington, U.S.A. The Company agrees to convert the alumina so provided. Hydro agrees to pay for the conversion. This Agreement is subject to and conditioned upon the execution by Hydro Aluminium a.s., a Norwegian corporation ("HAN"), and the Company of the Third Amendment to the Agreement to Toll Convert Alumina into Aluminum, dated as of July 12, 1987, as amended, between HAN and the Company. The parties agree as follows: 1. Term. The term of this Tolling Contract is ten years from 1 January 1997 through 31 December 2006. 2. Alumina Delivery. Throughout the contract term, Hydro will deliver alumina to the Company's unloading facility in Portland, Oregon for consignment to the Company under appropriate bills of lading or other documents of title. Delivery will be in accord with the shipping requirements specified in Exhibit A. The costs of unloading and storage, at the facility in Portland, and transfer to Goldendale will be borne by the Company and are included in the tolling fee. At all times, Hydro will maintain for the Company's use at Goldendale or its related storage facility, at a minimum, sufficient alumina inventory to support 30 days' scheduled production. The Company shall not use or process any alumina provided by Hydro hereunder for any purpose other than the conversion thereof into aluminum for Hydro in accordance with the terms of this Tolling Contract. 3. Metal Production. Throughout the contract term, the company will operate its potlines and the casting facility at the smelter exclusively to convert Hydro's alumina into standard aluminum products as specified by Hydro. Subject to the Company's product meeting the quality requirements of paragraph 11, Hydro will pay to the Company, a tolling fee for all aluminum metal manufactured using the entire production capability of the production facilities, which the Company shall dedicate solely to the tolling of Hydro's alumina in the quantity of at least 157,000 metric tons of aluminum metal annually. Subject to this annual requirement, the quantity of aluminum metal produced by the Company in any rolling three-month period from tolling Hydro's alumina hereunder may be not less than 37,288 metric tons and not more than 41,213 metric tons. If Hydro fails to deliver alumina sufficient for the Company to produce 157,000 metric tons of aluminum annually at a rate of 1.94 tons of alumina per ton of aluminum, and if such failure results in a production loss for the Company, Hydro will pay a tolling fee measured by the resulting lost production. 4. Tolling Fee. The tolling fee to be paid by Hydro to the Company will be a fraction of the London Metal Exchange ("LME") price for contracts for High Grade aluminum (99.7 or P1020), as follows: LME INDEX TOLLING FEE % OF $/TON LME CONTRACT P1020 --------- ------------------ Below 1,450 *** 1,450-1,700 *** Above 1,700 *** Effective from 1 January 1997 through 31 December 1997, the tolling fee shall be not less than $*** per metric ton. The LME price used for measurement purposes will be the LME cash settlement price as published in Metals Week, averaged for the three-month period immediately preceding the month of production. The tolling fee is applicable to all production of aluminum metal hereunder, as adjusted for the production of casthouse products as set forth in Section 5 or for the production of off-grade aluminum as set forth in Section 11. If during any three-month period, the weekly LME cash price on average is more than $20 per metric ton above the average LME three-month contract price (which condition is called "excess backwardation"), then the LME price for measuring purposes computed for such period (and for any continuing period until such excess backwardation ends) shall be the lower of the LME cash or three-month contract price. Thereafter, the measuring price shall again be the LME cash price. The tolling fee covers all costs of handling, storing and loading the aluminum metal produced hereunder until loaded on board railcar or truck at Goldendale. Hydro will have the right to store a maximum of 90 days inventory at Goldendale without additional charge and the Company shall issue to Hydro a warehouse receipt evidencing the finished goods stored. Hydro shall be entitled, at any time, to direct the Company to release some or all of such stored aluminum for sale. As may be directed by Hydro, and in accordance with appropriate bills of lading or other documents of title, the Company will load Hydro's 2 converted aluminum, for shipment to such location as Hydro directs. On average, at least 90% of the annual production will be delivered by the Company as P1020, subject to the production of casthouse products as set forth in Section 5 or the production of off-grade aluminum as set forth in Section 11. 5. Casthouse Production; Profit Sharing. It is understood that Hydro will require that substantial quantities of the aluminum be delivered in such forms (such as extrusion billet, foundry tee or sheet ingot) or with such alloy contents as shall cause the Company to incur operating production costs above those required to produce standard P1020 ingots (collectively "casthouse products"). All products of casthouse production delivered to Hydro shall be made from aluminum metal tolled for Hydro under this Tolling Contract or from additional aluminum metal provided by Hydro pursuant to the last paragraph of this Section 5. The Company will charge and Hydro will pay an additional casting charge for each casthouse product as follows: (a) For standard 6063 billet, the additional casting charge shall be *** cents per pound; (b) For standard unalloyed 1070 sheet ingot, the additional casting charge shall be *** cents per pound; (c) For other alloys or other forms, such additional charges shall be established by mutual agreement between Hydro and the Company as are appropriate to reflect the additional costs of producing such forms and alloys, in a manner consistent with the establishment of the additional charges set forth in paragraphs (a) and (b). The parties agree to meet f rom time to time, at the request of either party, to determine if changes in the casting charges are appropriate, taking into account the long-term, material changes, if any, in the Company's costs arising as a result of causes beyond the Company's reasonable control. In addition, for each alloy or form, Hydro agrees to pay the Company an amount (the "Profit Share") equal to ***% of the excess of the premium received by Hydro for such alloy or form under the terms of its contracts with its customers over the additional charges for such alloy or form payable by Hydro to the Company under the terms of this Tolling Contract. Such Profit Share shall be calculated on the basis of the relevant economic factors existing at the time Hydro enters into contracts with its customers. The calculation of Profit Share in each particular case shall be done in a manner consistent with the examples set forth in Exhibit B. In the event that Hydro and the Company mutually agree to a profit sharing arrangement with respect to a specific customer contract of Hydro different from that 3 specified herein, then Hydro and the Company shall enter into a written memorandum evidencing such other arrangement. Hydro agrees to place orders for at least 70,000 metric tons of casthouse products each year. Hydro will place orders for casthouse products in commercially reasonable lots that shall not exceed the reasonable capacity of the casthouse as determined by the mutual agreement of the parties from time to time. Hydro shall have the unilateral right to modify its production schedules within 45 days of production if the Company is physically able to accommodate the modifications taking into account its then existing commitments and labor force upon payment by Hydro of any extra costs incurred by the Company as a result of the modifications. The parties agree to pursue increasing casthouse production through the use of additional aluminum metal for the production of value-added products in the casthouse, on such terms and conditions as may be mutually agreed upon by the parties. Supplies of additional aluminum metal provided by Hydro for use in casthouse production shall be subject to such additional casthouse charges as may be mutually agreed upon by the parties, but not to the tolling fee for alumina hereunder. 6. Production Schedules. By the 15th of each calendar month, the parties will agree upon a schedule establishing estimated production requirements in reasonable detail for the next 120 days. Hydro may unilaterally modify any such schedule at any time and from time to time with respect to production to occur more than 45 days from the date of modification. Modification affecting production within the next 45 days may be made upon mutual agreement or unilaterally by Hydro upon payment of any extra costs incurred by the Company as a result of the modification. All production and delivery schedules will incorporate commercially reasonable conditions, including minimum quantity requirements and schedule adjustments for tooling changes and orderly staffing changes. It is understood that the parties will work together (a) to optimize productivity, production output, and quality, and (b) to permit Hydro and the Company to capitalize on market opportunities. Exhibit C states Scheduling Criteria and Delivery Schedules. 7. Alumina Source and Specification. The parties recognize that the smelting process and related environmental control is sensitive to the nature of alumina. By November 30 of each year the parties will seek to mutually agree upon an approximate schedule of alumina deliveries for the following year. Hydro will have the right to supply alumina so long as the alumina supplied by Hydro meets the specifications of Exhibit D. A set of core sources and a procedure for qualification of new sources will be mutually agreed upon. Hydro will use its best efforts to give the Company at least two months prior notice of any impeding change in the sources of its alumina, to the extent consistent with the alumina delivery schedule agreed upon for that year. 4 8. Alumina Usage. The Company will manufacture aluminum as specified by Hydro, which meets United States industry standards, f rom alumina at the rate of 1.94 tons of alumina per ton of aluminum computed on an annual basis, provided that the alumina meets the specifications of paragraph 7. Except as the parties may otherwise expressly agree, the rate referred to in the preceding sentence shall not be affected for any reason, including any event of force majeure. In the event of a failure by the Company to meet this production requirement from alumina supplied by Hydro, the Company shall be obliged to procure additional alumina or aluminum metal sufficient to meet such production requirement, without additional cost to Hydro. Hydro will credit the Company with the market value of any alumina saved by the Company's achieving greater than the required production efficiency, computed on an annual basis, provided that the aluminum produced as a result of such increased efficiency shall be credited to Hydro's account. The parties shall mutually agree upon the procedures for implementing such credits. It is understood that the alumina usage rate is to be based on the production of molten aluminum in accordance with industry standards as mutually agreed upon by Hydro and the Company, and shall be subject to verification in accordance with the provisions of Section 10. Alumina sampling and weight control will be in accordance with Exhibit E. The Company will bear the risk of loss or damage for alumina and aluminum from the time alumina is accepted at the unloading dock until aluminum is certified as loaded for shipment at Hydro's instructions. 9. Consumable Inventory. Hydro and the Company will discuss mutually agreeable arrangements for Hydro to offer magnesium, grain refiner and other raw materials to the Company at competitive prices. 10. Invoices and Payment. The Company will invoice Hydro weekly before 5:00 p.m. Eastern time, on Mondays (or if Monday is a holiday, then on the next business day) by facsimile transmission with each invoice reflecting the tolling fee for finished production for a seven-day period, plus charges for finished casthouse production in accordance with Section 5 hereof (taking into account any additional aluminum metal provided by Hydro) and such other charges as may be appropriate. Finished production means product in shipping condition, whether or not immediately shipped for Hydro. Cast metal which is not sawed at the time of such invoicing shall be invoiced at its P1020 value, with the applicable additional charge subsequently invoiced when such metal is sawed. Invoices will be paid by Hydro and received by the Company's bank within 25 days of facsimile transmission generally on a Thursday (or if Thursday is a state or national holiday, then on the immediately preceding business day). At the time of the payment of each invoice, Hydro shall also pay an amount equal to Hydro's good faith estimate of the Profit Share corresponding to such invoice in accordance with Section 5. Payments will be made in U.S. dollars by wire transfer to the Company's bank in immediately available Federal funds. The Company shall use its best efforts to provide Hydro with a report, in reasonable detail as specified by Hydro, by 5:00 p.m. Eastern time on the first business day of each 5 month, of the inventory, production and shipment tonnages for the immediately preceding month. Within 30 days following the end of each calendar quarter, Hydro shall determine the aggregate Profit Share corresponding to all invoices submitted by the Company during such quarter. If such aggregate Profit Share is greater than the aggregate estimated payments of Profit Share made by Hydro on such invoices, Hydro shall promptly remit the difference to the Company. If such aggregate Profit Share is less than the aggregate estimated payments of Profit Share made by Hydro on such invoices, then the Company shall credit such difference to Hydro's account on future payments to be made by Hydro to the Company hereunder. The parties agree to meet from time to time, at the request of either party, to review the Profit Share calculations, with each party to provide such work papers and other documentation as are reasonably necessary to conduct such a review. For a period of not more than one year after the end of each quarter, Hydro shall permit its books and records to be inspected upon reasonable notice and during normal business hours by an independent accounting firm of national standing of the Company's choice and at the Company's expense. The scope of such inspection shall be limited to determining the Profit Share due to Hydro under Section 5 for such quarter, and such accounting firm shall execute, prior to such inspection, an agreement with Hydro not to disclose the results of such inspection to any person or entity other than the Company and not to disclose to any person or entity, including the Company, the terms or provisions of any contract between Hydro and a customer of Hydro if that customer is also a competitor of the Company with respect to a particular product. Hydro shall have the right, at reasonable times and on reasonable notice, to conduct an audit, using its own personnel and/or an accounting firm of national standing of Hydro's choice and at Hydro's expense, of the Company's books of account, production records and physical inventory in order to verify the alumina usage rate, the invoices and reports submitted by the Company, and such other matters as Hydro may reasonably need to verify in connection with the Company's performance of its obligations hereunder. 11. Product Quality. The Company will manufacture all aluminum metal and casthouse products to the specifications established in writing by Hydro, provided that if the Company does not believe that it can meet such specifications, it shall so notify Hydro within 10 days after its receipt of such specifications. The Company will provide both metallurgical and physical inspection of all products prior to release for shipment. In case of defective production, Hydro and the Company will have the rights provided in paragraph 12. Hydro will have no obligation to take a product or pay a tolling fee for any product which fails to meet specification. Hydro may take out-of-specification product pursuant to Section 3, in which event the tolling fee for such out-of-specification product shall be reduced, on a per pound basis, as follows: 6 Below 99.7 grade aluminum to and including Alcoa P1535 *** cent Below Alcoa P1535 to and including Alcoa 2060 *** cents Below Alcoa 2060 to and including Alcoa 2590 *** cents Below Alcoa 2590 to and including MTO *** cents Below MTO to and including MT1 *** cents Below MT1 to and including MT2 *** cents Below MT2 *** cents Otherwise the Company shall purchase the related alumina from Hydro at Hydro's documented cost and disposition of such product is at the Company's risk. 12. Production Default Provisions. it is understood that each party will have made substantial commitments in expectation that deliveries of alumina and production will take place in accordance with the terms of this Tolling Contract. The following provisions are intended to assure that both parties have every opportunity to achieve the intended benefits of this Tolling Contract, but to provide an orderly process for contract termination if necessary. Hydro will have the right at all times to inspect product and the production process and to offer technical assistance and advice. Hydro shall notify the Company as promptly as possible and in any event within 10 days of discovery of any substandard product or other failure of performance by the Company. If for any period exceeding 90 days more than 4% of the Company's production fails to meet the specifications and/or production schedules required hereunder, then Hydro shall undertake in good faith to provide technical assistance and advice and to propose changes in the Company's production techniques in order to enable performance by the Company of its obligations hereunder. A reasonable time shall be allowed for the good faith efforts of Hydro to provide such advice and of the Company to implement changes proposed by Hydro. Hydro shall give written notice to the Company at such time as it believes that a reasonable time has elapsed for such good faith efforts by Hydro and the Company. If more than 4% of the Company's production fails to meet the specifications and/or production schedules required hereunder for an additional 90 days following such notice by Hydro, then Hydro may terminate this Tolling Contract on 120 days notice. Such remedy shall be in addition to, and not in lieu of, all other remedies as Hydro may have at law or in equity for any breach or default by the Company under this Tolling Contract, including the recovery by Hydro of its cost of settling Hydro's position on LME 7 forward contracts based on this Agreement, and Hydro shall not be required to make an election with respect to its remedies for any such breach or default by the Company. During the termination period, production will be maintained at the maximum level necessary or possible to work off inventories of raw materials while permitting an orderly transfer or closure of operations at the end of the period. If by reason of force majeure, performance by a party of its obligations hereunder is substantially impaired for a period which is reasonably expected to continue for more than 180 days, then the other party may by 30 days prior written notice, terminate this Agreement. 13. Facility Maintenance and Insurance. At all times, the Company will maintain the smelter and all ancillary loading and unloading facilities in first class operating condition. The Company will maintain all-risk casualty insurance in amounts sufficient to repair or replace any facilities damaged in an insured loss, and comprehensive general liability insurance covering liability for personal injury, death or property damage, with policy limits of not less than $____________ per occurrence and $____________ total liability. All such policies shall name Hydro as an insured, to the extent of its insurable interests, shall provide that the insurer may not cancel or refuse to renew such policies without providing Hydro 30 days' prior written notice thereof and shall be in form and substance reasonably satisfactory to Hydro. Hydro will certify to the Company's insurance underwriter on request and from time to time the amount and provisions of its product liability insurance coverage applicable to products manufactured by the Company. On request by the Company, and to the extent permitted by Hydro's insurers, Hydro agrees to name the Company as an additional insured on such insurance, the additional premium, if any, to be paid by the Company. 14. Technology. Hydro agrees to make its expertise and technical assistance available to the Company in order to optimize and upgrade its Soederberg potlines, upon such terms as the parties may mutually agree. Hydro also agrees to discuss its possible participation in the improvement and expansion of the Company's casthouse. At the request of the Company within two years after the date hereof, Hydro will cause an engineering audit of the Company's Soederberg potlines to be performed at no charge to the Company. 15. Ownership of Aluminum and Alumina; Insurance. (a) Title to all inventories of alumina and title to all aluminum metal delivered from the casthouse within the scope of this Tolling Contract will at all times remain vested in Hydro and not in the Company, and the Company shall use and process such alumina in strict accordance with the provisions of Section 1 hereof. All work-in-process, including molten aluminum not yet delivered from the casthouse, will belong to the Company and not to Hydro. The Company shall have title to all residue and slag, including dross, resulting from conversion of the alumina and all conversion process by-products of the 8 alumina, and the Company shall process, recycle or dispose of the same in accordance with all applicable laws. (b) Subject to paragraph 15, the Company covenants that all alumina delivered by Hydro pursuant to this agreement that has not been converted into aluminum and all converted aluminum (except molten aluminum in pots) that has been produced f or Hydro's account shall be at all times free and clear of any lien, charge or encumbrance of any nature whatsoever excluding only those in favor of persons other than the Company created by Hydro and that, upon request by Hydro following the occurrence of a default by the Company as defined below, it will surrender all such alumina or converted aluminum and alumina subject to paragraph 12, to Hydro. (c) Solely in order to protect Hydro's property interest in all alumina and all converted aluminum to which this Agreement relates against any claim made in respect thereof by a creditor of the Company or others claiming through the Company, the Company grants Hydro a security interest in all of the Company's right, title and interest in alumina delivered by Hydro (whether at the Company's unloading facilities or at the smelter) and in finished aluminum goods now and hereafter produced for Hydro's account in the Company's possession, whether located at the Company's address set forth herein or elsewhere, and all proceeds thereof (the "Collateral"), to secure performance of all obligations of the Company to Hydro arising out of the preceding subparagraph, which security interest shall be prior to all other security interests in the Collateral. The following shall constitute defaults by the Company under this security agreement: (i) If the Company shall (A) be generally not paying its debts as they become due, or (B) file any petition or answer seeking for itself any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future bankruptcy, insolvency or similar statute, law or regulation, or (C) file any answer admitting or not contesting the material allegations of a petition filed against the Company in any such proceeding, or (D) seek or consent or acquiesce in the appointment of any trustee, custodian, receiver or liquidator of the Company or of all or any substantial part of its properties or, (E) take corporate action for the purpose of any of the foregoing, or (F) if without the consent or acquiescence of the Company, an order shall be entered constituting an order for relief or approving a petition for relief or reorganization, or any other petition seeking any reorganization, arrangement, competition, readjustment, liquidation, dissolution or other similar relief under any present or future bankruptcy, insolvency or similar statute, law or regulation, or (G) if, without the consent or acquiescence of the Company, an order shall be entered appointing a trustee, custodian, receiver or liquidator of the Company or of all or any substantial part of the properties of the Company; (ii) The Company's demonstrated and continuing inability pursuant to paragraph 12 to deliver finished aluminum goods to Hydro in the quantities and quality required under this Agreement, when called for by the terms hereof; 9 (iii) Breach by the Company of a material obligation under this Agreement; or (iv) Any assertion of any right in the Collateral by any other creditor. In the event of a default under this provision, Hydro shall immediately have the rights of a secured party after default under a security agreement, and the Company agrees to pay reasonable attorneys' fees and legal expenses incurred by Hydro in enforcing such rights. The exercise by Hydro of its rights set forth in this subparagraph 14(c) shall be solely for the purpose of protecting its property interest in alumina and converted aluminum and shall not effect a termination of this Agreement nor alter the rights and obligations of the parties under paragraph 12 or any other provision hereof. (d) The Company agrees that it shall execute and deliver to Hydro such financing or continuation statements as Hydro may request evidencing the Company's status as consignee with respect to alumina delivered by Hydro and with respect to finished aluminum held for the account of Hydro and with respect to finished aluminum held for the account of Hydro, and evidencing Hydro's status as a secured party with respect to the Collateral. Hydro may, at its expense, record any such financing or continuation statements. The Company shall deliver to Hydro any negotiable document of title received for alumina or converted aluminum, title to which, in accordance with this paragraph 14 is in Hydro, forthwith upon the Company's receipt thereof. (e) Each party will maintain casualty insurance in amount and form desired to protect its interests in such inventory. Each party waives its right of subrogation against the other for matters which are or could be insured against pursuant to this subparagraph. 16. Non-Payment. If for any reason other than the Company's failure of performance (and then only after notice to the Company and only to the extent of such non-performance) Hydro fails to deliver alumina to the Company or fails to pay the Company in accordance with paragraph 10, the Company shall be entitled to sell finished product to third parties in such quantities as may be necessary to compensate the Company for all tolling fees and other amounts earned and for the additional costs related to such non-delivery or non-payment. Such sales may be made only after 21 days actual notice or notice by certified mail to Hydro and shall be made in accordance with the Uniform Commercial Code. Hydro hereby grants to the Company a limited security interest in the aluminum inventories on hand from time to time for this purpose, which the Company may assign to its lenders. 17. Force Majeure. Without limiting the Company's obligations set forth in the last sentence of paragraph 8, each party will be excused from performance hereunder as a result of an event of force majeure. Force majeure is defined as any event not reasonably within the control of a party, including but not limited to damage, destruction, or failure of the works or facilities required for performance of a party's obligation hereunder (other than 10 as a result of the Company's breach of its obligations under Section 13), natural disasters, injunctions, and work stoppages whether lawful or not resulting from any labor dispute, but excluding changes in rates for electric power. Each party will promptly notify the other party of such an occurrence, and performance hereunder shall be suspended so long as any such event prevents such performance. Each party will maintain appropriate business interruption insurance to protect its interests. Nevertheless, each party will take all reasonable steps to maintain deliveries of alumina and production of aluminum and to overcome the effects of force majeure. In the event that a party invokes an event of force majeure hereunder on one or more occasions, the term of this Tolling Contract may be extended, at the option of the other party exercisable from time to time on or before the otherwise applicable expiration of the term hereof, for a period of time not in excess of the aggregate amount of time for which the party claimed to be excused from performance hereunder due to one or more events of force majeure. 18. Economic Hardship. In the event that a party believes that its performance as agreed hereunder has been made impracticable by, or all or part of its capacity to perform has been affected by, the occurrence of a contingency the nonoccurrence of which was a basic assumption on which this Tolling Contract was made, such party may give written notice to the other, and the parties agree to meet to discuss a solution that will not unduly prejudice the rights of either party hereunder. 19.

Loose Packed Attrition Index 30% maximum N/A 25 EXHIBIT E SAMPLING, ANALYSIS AND WEIGHING Sampling One sample of each shipment of alumina shall be taken in accordance with the sampling procedures applicable to the load port, which shall be in accordance with international practice. The Company shall have the right to have a representative present at such sampling at its own expense. Such sampling shall be deemed to be a representative sample of the alumina delivered in that shipment. The sample shall be divided into four portions. One portion shall be promptly dispatched to Hydro, one portion shall be promptly dispatched to the Company, one portion shall be used by the alumina producer for analysis, and Hydro shall ensure that one portion (the referee sample) shall be held by the alumina producer for 180 days after the date of the shipment, and then disposed of unless Hydro or the Company has requested in writing that it shall be retained for a longer period. The cost of sampling and dispatch to the Company shall be for the account of Hydro. Analysis of Quality Hydro shall arrange for the alumina producer to analyze the sample retained at the load port for each shipment of alumina within five working days in accordance with the producer's relevant standard practice. Hydro shall send to the Company the results of such analysis (by cable, telex or fax transmission) within 10 days after departure from the port of loading. Hydro shall provide to the Company an original of the certificate of analysis stating the results of the analysis as early as practicable. If the analysis carried out by the producer shows that the sample analyzed conformed with the quality specifications, it will be presumed that the entire shipment from which the sample was taken conforms with such specifications. Within 30 days after receipt of the sample, the Company may notify Hydro that the alumina does not conform to the quality specifications. If the Company does not notify Hydro within this period, the alumina delivered shall be deemed to comply with such specifications. If the Company does notify Hydro within the period, Hydro shall advise the Company within 10 days after such notification is received whether or not Hydro agrees with the Company's analysis. If Hydro does not agree, the referee sample will be analyzed as soon as possible by Alcoa (the "Referee Laboratory"). The Referee Laboratory will analyze the referee sample in accordance with applicable standard analytical procedures for alumina 26 analysis, and a copy of its analysis shall be made available to both the Company and Hydro. Such analysis shall be final and binding, and the quality of the alumina contained in the relevant shipment shall be deemed to be the same as that of the referee sample. The cost of any referee analysis will be borne by the party whose results differ most from those given by the Referee Laboratory. Weight Delivery shall be based on the bill of lading weight of the alumina as determined by draft survey, carried out by a marine surveyor appointed by Hydro on the basis of the ship's displacement at the time of loading. 27 EXHIBIT F ENVIRONMENTAL EXCEPTIONS [To be supplied.] 28 EXHIBIT G NOTICE PROVISION Any notices required to be provided to either party to this Agreement shall be given to the following persons at the addresses set forth below: The Company: Brett Wilcox, Chairman Goldendale Aluminum Company 85 John Day Dam Road Goldendale, WA 98620 Todd A.
