(a) Each Owner agrees to pay the Operator, in the manner provided in Section 5.7.3, for each Extra requested by it as determined in accordance with the cost accounting system for the Plant established by the Owners Committee. The cost accounting system shall be installed and used throughout the term of this Agreement by the Operator to determine the proper allocation among the Owners of the costs of operating the Cast House. (b) If the Owners Committee does not approve a proposed change in the cost accounting system requested by an Owner, the Owner requesting a change shall have the right to request the Auditors to review the cost accounting system then being employed to ascertain whether such system should be changed in the manner sought by such Owner in order more accurately to allocate costs among the Owners. The expenses of such Auditors' review shall be borne by the Owner which requested the review, if the Auditors determine no change is required, or by the Owner which voted against the requested change, if the Auditors recommend such change. Any change in such system recommended by the Auditors shall be effective for the calendar months following the calendar month in which the request was made for review by the Auditors. 5.7.3 Calculation of Charges. The Operator shall calculate charges for Operating Costs, Extras and other amounts as may be due from the Owners or a particular Owner, prepare statements to the Owners relating to their respective shares of Operating Costs and such other amounts, and receive and deposit into the Operator's bank account(s) all sums paid to the Operator for the account of the Owners, all in the manner provided in the procedures established by the Owners Committee. 5.7.4 Payment of Charges. (a) Charges for Operating Costs, Extras and other amounts as may be due under this Agreement shall be collected from the Owners by the Operator at the times and in the manner provided in the procedures established by the Owners Committee. 15 (b) In general, it is intended that the Operator shall have neither more than nor less than such funds as are required to operate the Plant efficiently. Each Owner shall make funds available so they may be drawn on a daily basis through the Operator's bank account. The procedures to be established by the Owners Committee shall require the Operator to give the Owners Committee periodic cash forecasts and reasonable advance notice of any major payments that may be required to be made. (c) Notwithstanding any dispute with respect to the amount requested to be paid by an Owner, each Owner shall pay the amount requested within ten (10) days after the receipt of such request, all payments being subject to adjustment as provided in Sections 5.7.5 and 5.7.6. 5.7.5 Year End Adjustments. (a) Within ninety (90) days after the end of each calendar year the Operator shall submit to the Owners: (i) financial statements showing the items of the Operating Costs for such year, (ii) a statement showing the Extras performed during such year, and (iii) a statement showing any other amounts payable by each Owner or received from each Owner under this Agreement, all of which statements shall reflect adjustments for partial calendar months included in such calendar year and shall be audited by the Auditors. (b) Within ten (10) days after the receipt of such statements, all such adjustments, including any repayment from the Operator, shall be made as may be necessary to make the respective payments of each Owner for such year conform to its respective obligations under this Agreement for such calendar year, as shown by such statements. 5.7.6 Resolution of Disputed Charges. (a) If any Owner disputes the calculation or allocation of charges for Operating Costs, Extras or any other amounts hereunder, it shall give notice of such dispute to the Operator and the other Owners setting forth the details of its dispute. If the disputing Owner and the Operator cannot satisfactorily resolve the dispute within thirty (30) days, the disputing Owner may request the dispute to be referred to the Auditors, whose decision shall be binding on the parties. Payments arising out of resolution of such disputes shall be made within ten (10) days of the resolution. (b) If the Auditors recommend an adjustment which exceeds the lesser of $100,000 or five percent (5%) of the amount in dispute, the Auditors' fees shall be paid by the Operator. Otherwise, the disputing Owner shall pay the Auditors' fees. 5.7.7 Financing and Other Costs. Each of the Owners shall pay and be responsible for its own (i) charges for interest and other costs related to financing its payments required to be made hereunder, and (ii) costs of transportation of Alumina. 16 5.7.8 Power Contract. In the event that the Owners agree that the current power contracts entered into by the Operator for the supply of electrical power to the Plant may be assigned to an Owner, pro rata, the Owners shall enter into an agreement containing terms and conditions acceptable to the Owners which provides, inter alia, that the Owners shall have the obligation to supply their pro rata share of electrical power to the Plant for the operation thereof at its then rated capacity and that the Owner to which its pro rata portion of the power contract is assigned shall reimburse the other Owner for any increase in Operating Costs attributable to any replacement source of electrical power and for any reduction in capacity of such other Owner as a result of any failure to provide such electrical power. 5.7.9 Management Fee. For each calendar quarter during the term of this Agreement, GAC shall pay to the Operator, quarterly in arrears, a fee (the "Management Fee") as full compensation for all services of the Operator provided under this Agreement. The Management Fee payable by GAC shall be based solely upon the value of Aluminum Product produced at the Plant. The Management Fee for a calendar quarter shall be an amount equal to the product obtained by multiplying (x) the amount in pounds of Aluminum Product produced for the account of GAC as an Owner during the applicable calendar quarter and (y) 3/4 of 1% of the arithmetic average of the daily settlement price per pound of aluminum on the London Metal Exchange ("LME") as published in "Metal Bulletin" as the seller's price under the caption "Daily Metal" for each calendar month during the calendar quarter immediately preceding the calendar quarter for which payment is to be made. The LME settlement price is a basis agreed to by the parties upon which a value of Primary Aluminum in major free world markets can be established. If a significant change occurs in its historic relationship to free world values, and such change is for a duration of nine (9) months or longer, the parties, upon the request of either of them, agree to meet to discuss in good faith an alternative basis for establishing such value. If the LME shall cease to trade aluminum or the aluminum settlement price of the LME is no longer published, the "value of Primary Aluminum" shall mean the generally accepted substitute for the aluminum settlement price of the LME. If there is no such generally accepted substitute the parties in good faith shall select a substitute. Failing such agreement, the "value of Primary Aluminum" shall be submitted to arbitration as provided in Section 13.11. The Operator shall invoice GAC for the amount of the Management Fee due for each calendar quarter promptly after the end of such calendar quarter and GAC shall pay such amount within ten (10) calendar days after receipt of such invoice.

The preceding sentence shall not be deemed to limit the Operator's obligation to repay any amounts billed to and paid to it as Operating Costs which are ultimately determined by the Auditors not to be Operating Costs. Article VII CONVERSION Section 7.1 Conversion Rights and Obligations. 7.1.1 Obligation to Convert. The rights and obligations of the Owners to convert Alumina to Molten Metal or Primary Aluminum at the Plant are set forth in this Article VII. (a) Except as otherwise provided in this Agreement (i) the Operator shall endeavor to operate the Plant at Rated Capacity or higher; (ii) each Owner agrees to supply or cause to be supplied to the Plant the quantity of Alumina necessary for the production of such Owner's Basic Tonnage and Allocated Excess Tonnage, if any; and (iii) each Owner will be entitled to Molten Metal produced at the Plant in proportion to its Basic Tonnage and its Allocated Excess Tonnage, if any, provided it supplies Alumina for conversion in accordance with the provisions of this Article VII. 20 7.1.2 Reduction of Basic Tonnage. (a) If, from time to time, an Owner desires to reduce its Basic Tonnage, it shall notify the other Owner, at least ninety (90) days prior to the date that it desires the reduction to become effective, of the amount of the reduction, the date the reduction is to be effective and the period of time (which shall not be less than ninety (90) days) that such reduction is to be in effect. (b) If an Owner gives notice to reduce its Basic Tonnage, the other Owner (the "eligible Owner") shall have the right to assume all or part of the available tonnage or conversion capacity, for all or a portion of the time that such tonnage or conversion capacity shall be made available, such right to be exercised by giving notice to the Owner seeking to reduce its Basic Tonnage, within sixty (60) days of receipt of the notice of reduction, specifying the amount of the available tonnage to be assumed and the period of time that such assumption is to be in effect. (c) The giving of the notice of assumption specified in paragraph (b) shall thereby commit the eligible Owner to convert the tonnage in the amount and for the time therein designated upon the terms herein provided. Any portion of the reduction in tonnage or tolled tonnage of an Owner which is committed for by the other Owner pursuant to this Section 7.1.2 for any period of time shall not be part of the Basic Tonnage of the Owner making the reduction for such period and shall for such period be part of the Basic Tonnage of the Owner which committed for the tonnage made available by such reduction or offer to Toll. 7.1.3 Failure to Convert Basic Tonnage. If (i) an Owner has given notice to the other Owner pursuant to Section 7.1.2 to reduce its Basic Tonnage and the other Owner does not commit to convert all of the tonnage made available by such reduction pursuant to Section 7.1.2, or (ii) an Owner fails (for any reason, including a reason constituting force majeure) to supply Alumina sufficient for the production of its Basic Tonnage and the other Owner does not utilize the tonnage made available by such failure, then the Owner making the reduction or failing to supply, as the case may be, shall pay to the other Owner, within thirty (30) days after the end of each calendar month, the amount of any increase in the Operating Costs per Ton incurred by such other Owner during such calendar month which is attributable to such reduction or failure to supply. The amount of any such increase shall be determined by the Operator by reference to the cost accounting system utilized for the Plant, and shall be subject to possible adjustment as provided in Section 5.7.5. 21 7.1.4 Available and Allocated Excess Tonnage. (a) The Operator shall promptly notify the Owners of the availability of any capacity to produce Primary Aluminum in excess of Rated Capacity (the amount of such excess expressed in Tons being herein referred to as "Available Excess Tonnage"). The notice shall specify the amount of Available Excess Tonnage and the approximate date such tonnage can be delivered. Each Owner may request the Operator at any time to determine the amount of Available Excess Tonnage. Each of the Owners shall give the Operator notice within thirty (30) days after receipt of the Operator's notice stating the portion of its share of such Available Excess Tonnage, such share to be based upon each Owner's Basic Tonnage, that it desires to utilize and the period during which it desires to commit for such use. If any Owner fails to give such notice or commits for less than all of its proportionate share of such Available Excess Tonnage the other Owner shall have the option to convert all or any part of the remaining portion of the Available Excess Tonnage. An Owner that has elected to take less than all of its Available Excess Tonnage shall have the right, upon six months notice to the other Owner, to convert all or any part of its proportionate share of Available Excess Tonnage allocated to the other Owner. (b) Available Excess Tonnage which is allocated to an Owner for any period of time is herein called the "Allocated Excess Tonnage" of such Owner for such period. (c) The Owners shall bear any increase in Operating Costs per Ton of Molten Metal incurred because the Plant is being operated in excess of Rated Capacity in proportion to their respective Allocated Excess Tonnages. The amount of any such increase shall be determined by the Auditors, and the costs of such determination shall be borne by the Owners in proportion to their respective Allocated Excess Tonnages. 7.1.5 Production Deficiencies. If at any time for any reason (not attributable to the default of an Owner) the production of the Plant is insufficient to meet scheduled deliveries of Molten Metal, deliveries of Molten Metal shall be reduced as follows: (i) the delivery of Allocated Excess Tonnages, if any, shall be reduced in proportion to the Owners' respective Allocated Excess Tonnages and, if there is any remaining deficiency, (ii) deliveries of Basic Tonnages to the Owners shall be reduced in proportion to their respective Basic Tonnages. Section 7.2 Alumina Supply. 7.2.1 Alumina Delivery Obligations. Alumina shall at all times be delivered to the Plant by each Owner or for that Owner's account in sufficient quantities so that, with due consideration for the quality of Alumina and the capacity of the alumina storage facilities at the Plant, there shall be sufficient Alumina on hand at all times for the Plant to produce the particular Owner's Basic Tonnage and Allocated Excess Tonnage. 7.2.2 Unloading of Alumina. (a) Alumina to be provided by each Owner shall be delivered at the Plant in a vessel with acceptable storage conditions and unloading characteristics reasonably adapted to the characteristics of the facilities for the delivery of Alumina at the Plant. Alumina furnished by an Owner may be commingled and shipped in common with Alumina belonging to the other Owner, and commingled at the Plant, provided that Alumina from different sources shall not be commingled. 22 (b) Each Owner shall pay all freight and shall be responsible for all other charges to effect delivery of its Alumina to the Plant. All unloading costs shall be Operating Costs. (c) If extra demurrage, freight or other costs are incurred by an Owner by reason of any other Owner's failure to comply with an agreed upon delivery schedule or otherwise through the fault of any other Owner, the Owner at fault shall pay the non-defaulting Owner upon demand an amount determined by such non-defaulting Owner as sufficient to compensate the non-defaulting Owner for excess costs so incurred by them. The defaulting Owner shall have the right to review the records upon which such calculation was based. (d) The Operator shall keep complete records with respect to the Alumina furnished and converted for each Owner. 7.2.3 Quality of Alumina. If for any reason an Owner does not supply Alumina which meets the minimum specifications set forth in Exhibit A to this Agreement, the Operator may, but shall not be required to, accept such Alumina for conversion. If such Alumina is accepted for conversion, the Operator shall determine the difference, if any, in costs of handling and processing such Alumina into Molten Metal, and any increase in costs shall be for the account of such Owner. The amount of any such increase shall be determined by the Operator, and shall be subject to possible adjustment as provided in Section 5.7.5. Section 7.3 Title. 7.3.1 Title to the Alumina furnished by an Owner and to the Molten Metal to which that Owner is entitled hereunder and to the Primary Aluminum cast therefrom shall be in that Owner, provided that where Alumina or Molten Metal is commingled in storage or processing each Owner shall have an undivided interest in such Alumina to the extent of the amount supplied and in such Molten Metal to the extent of its Basic Tonnage plus Allocated Excess Tonnage, if any. 7.3.2 At an Owner's request, the Operator shall (i) issue a holding certificate in customary form, or (ii) execute such financing statements or documents of similar nature as may be requested by the Owner to evidence its ownership of Alumina, Molten Metal or Primary Aluminum, as the case may be. Section 7.4 Shipment, Delivery, Sampling and Weighing. 7.4.1 Production Schedules and Deliveries. (a) So long as the Aluminum Supply Agreement shall be in effect, Molten Metal produced at the Plant shall be allocated first to delivery under and in accordance with the terms of the Aluminum Supply Agreement, for the credit of each Owner in accordance with its Interest. (b) Primary Aluminum produced at the Cast House shall be delivered to the Owner entitled thereto pursuant to its instructions immediately upon completion of production of such Primary Aluminum. Deliveries shall be made to the Owners at the Plant on rail cars, trucks or other forms of transport. 23 (c) The Owners shall be advised periodically of Plant production schedules and the Owners shall arrange among themselves to take delivery of Molten Metal or Primary Aluminum in amounts and at intervals which are consistent with the Plant's production capacity and storage facilities. If the Owners are unable to agree upon a schedule consistent with the Plant's production capacity and storage facilities, deliveries shall be made by the Operator pursuant to this Section 7.4.1 in as equitable a manner as possible, giving due regard to the Basic Tonnages and Allocated Excess Tonnages of the Owners. 7.4.2 Failure to Take Delivery. If production is lost or increased costs are incurred due to the failure of an Owner to take delivery of Primary Aluminum in accordance with established schedules, the costs resulting from such reduced production or increased costs shall be for the account of such Owner. The amount of any such costs shall be determined by the Operator, and shall be subject to possible adjustment as provided in Section 5.7.5. 7.4.3 Sampling, Analysis and Weights. (a) The Owners Committee shall from time to time establish procedures for representative sampling and analysis of Alumina, Molten Metal and Primary Aluminum in accordance with good industry practice to insure that the Alumina delivered to the Plant, the Molten Metal produced at the Plant and Primary Aluminum received by the Owners from the Plant comply with the quality standards established by the Owners Committee. The Operator shall conduct such representative sampling and analysis in accordance with the procedures established by the Owners Committee. (b) Unless the Owners Committee unanimously agrees otherwise, the Operator shall use its best efforts to produce Molten Metal (i) first, in accordance with the specifications therefore in the Aluminum Supply Agreement, and (ii) thereafter, which has a minimum purity of ninety-nine and seven-tenths percent (99.7%) aluminum and Primary Aluminum which meets Aluminum Association standards. (c) The quantity of Alumina delivered in each shipment shall be taken from the bill of lading for that shipment, provided that such weight may be confirmed or checked by vessel displacement survey in light and loaded condition at the Plant or, at the Operator's discretion, may be determined or checked by scale weights. The quantities of Molten Metal and Primary Aluminum delivered shall be determined by scale weights. Weights shall be certified by the Operator to the Owners and the same weighing devices or methods shall be uniform on shipments to the Owners. Analyses and weights so made shall be presumptively correct, but each Owner shall have the right to investigate such analyses and weights and the method of determining same and to check the same by other analyses and weights made at its own expense, and mistakes when ascertained shall be promptly corrected. 24 7.4.4 Storage. (a) If an Owner so requests, the Operator shall place such Owner's Primary Aluminum in storage at the Plant for a handling charge covering costs which shall be determined by the Operator and billed to that Owner. (b) At an Owner's request, the Operator shall take such commercially reasonable measures as appropriate to segregate all Primary Aluminum stored for that Owner. (c) As of the end of each calendar month, the Operator shall inform each of the Owners regarding the quantity and composition of Primary Aluminum products in storage. 7.4.5 Markings. At an Owner's request and at such Owner's cost, the Operator shall mark all Primary Aluminum products owned by that Owner with a distinctive mark acceptable to that Owner which shall be sufficient to identify that product as the property of that Owner. Section 7.5 Cast House. 7.5.1 Use of Equipment in Cast House. (a) The Cast House time available for casting Molten Metal on behalf of the Owners shall be allocated between the Owners in proportion to their respective Basic Tonnages and Allocated Excess Tonnages, if any. (b) Not later than 25 days before the beginning of each calendar month, the Owners shall notify the Operator as to the Cast House capacity for which they wish to subscribe with respect to each form of Primary Aluminum. When the Cast House capacity so subscribed for a particular form of Primary Aluminum exceeds the available capacity, then the Operator shall allocate the available capacity between the Owners in proportion to their Basic Tonnages and Allocated Excess Tonnages, if any, and shall consult with each Owner regarding alternative forms of Primary Aluminum. Not later than 18 days before the beginning of such calendar month the Operator will notify the Owners of the Cast House capacity allocated to them with respect to each form of Primary Aluminum. (c) If during any calendar month the actual production of any form of Primary Aluminum by the Cast House is less than the Cast House capacity subscribed for in such period for that form of Primary Aluminum, the Cast House capacity allocated to each Owner with respect to that form of Primary Aluminum shall be reduced in proportion to the Owners' respective Allocated Excess Tonnages and, if there is any remaining deficiency, such allocated capacity shall then be reduced in proportion to the Owners' respective Basic Tonnages. Similar adjustments shall be made to the extent that the Cast House has insufficient capacity to produce alternative forms of Primary Aluminum requested by an Owner as a result of a reduction in allocated capacity under the preceding sentence. (d) The rules governing the allocation of Cast House capacity to give effect to the provisions of clauses (a) - (c) of this Section 7.5.1 shall be determined by the Owners Committee. 25 Article VIII INSURANCE AND CASUALTY Section 8.1 Insurance. 8.1.1 Coverage Requirements. The Operator shall be, and shall cause each of the Owners to be, a named or additional insured on all public liability, property and casualty insurance policies applicable to the Plant and the Plant Assets. The Operator shall also maintain such other insurance relating to conversion operations of the Plant necessary to protect the Owners' interests, including insurance on Alumina upon discharge at the Plant and Primary Aluminum while in storage at the Plant. The initial insurance requirements are set forth in Exhibit E, and such requirements may be changed from time to time by the unanimous vote of the Owners Committee. 8.1.2 Product Liability Coverage. The Owners agree that each will separately insure for all product liability claims relating to Primary Aluminum sold by such Owner. The Owners further agree that each will indemnify and hold the other Owner and the Operator harmless from any loss, cost, damages or liability of any nature whatsoever arising out of any product liability claim relating to such Owner's Primary Aluminum, and that any such liability shall survive the termination of this Agreement. Each Owner will deliver to the Operator and to the other Owner certificates of insurance evidencing their product liability coverage with commercially reasonable limits and containing endorsement naming the other Owner, its Affiliates and the Operator as additional named insureds, waiving subrogation against the other Owner, its Affiliates and the Operator, providing that such coverage shall be primary to any other coverage as to such Owner's Primary Aluminum and product liability claims arising therefrom and providing at least ten (10) business days notice of modification or cancellation of coverage. Section 8.2 Casualty. If the Plant or the Plant Assets are damaged or destroyed in whole or in part, in any respect, the Operator shall repair the damaged portion or rebuild or replace the destroyed portion in such manner as to restore the same as nearly as possible to the capacity thereof immediately prior to such damage or destruction, except that if the cost of repairing such damage exceeds $2.5 million, the Owners must consent unanimously to such repairs. The Operator shall not be obligated to expend for such purpose more than the proceeds of its insurance plus any amounts paid to it by the Owners on account of any deductibles and self-insurance. Section 8.3 Condemnation. In the event of condemnation of a portion of the Plant which adversely affects the production capacity or efficiency of the Plant, the Owners shall share in the production of the Plant in the manner specified in Section 7.1.5. The Operator shall take such action as is necessary, consistent with prudent business practice, to use the proceeds of condemnation to restore the capacity and efficiency of the Plant as it or they existed prior to such condemnation, unless otherwise instructed by the Owners, in which case the proceeds shall be divided between the Owners in proportion to their respective Interests. 26 Article IX RESTRICTIONS ON DISPOSITION OF PROPERTY OR INTERESTS Section 9.1 Transfers of Interests. 9.1.1 Restriction. Except as otherwise provided in this Article IX or in Article X, neither this Agreement nor any Interests shall at any time be transferred by any Owner without the express prior written consent of the other Owner. For purposes of this Article IX and Article X, transfer shall mean any sale, assignment, conveyance, exchange or other transfer. 9.1.2 Transfers to Affiliates. An Owner may transfer its entire Interest to an Affiliate, provided (a) such Affiliate shall become a party to this Agreement and shall expressly assume the due and punctual performance of all of the obligations of the transferor hereunder, (b) any such assignment shall not release the transferor from any obligations under this Agreement except to the extent that such obligations are performed by the transferee, and (c) the Parent Guarantee delivered by a Parent Guarantor with respect to the obligations of the transferor Owner is amended, if requested by the other Owner, to include a guarantee of the obligations of such transferee. 9.1.3 Transferee to Become Party to this Agreement. In the event of a transfer to a third Person of all or a portion of an Interest, such third Person shall execute and become a party to this Agreement and such transfer shall become effective only upon such execution. This Section 9.1.3 shall not apply to a Secured Party which shall acquire an Interest in accordance with Section 9.2.3, unless such Secured Party shall retain and not transfer its ownership of the acquired Interest, but shall apply to any Person to which a Secured Party shall transfer such Interest. 9.1.4 Reconstitution of Interests. The Owners acknowledge that, subject to their unanimous consent, it may at some future time be in their mutual best interests to reconstitute each of their Interests by each Owner conveying to the other Owner an undivided interest in the conveying Owner's Owner's Plant Assets (the "Reconstitution"), so that thereafter each Owner would hold a pro rata undivided interest as tenant in common (having waived all rights of partition) in all of the fixed and movable property and assets then comprising the Plant. Any such Reconstitution shall not affect the rights and obligations of the parties set forth in this Agreement except as specifically provided for in this Article IX and Article X. 9.1.5 Transfers of Part of an Interest. Subject to Section 9.1.6, in the event of a transfer by an Owner of a portion of an Interest, as provided for herein, before the occurrence of the Reconstitution, the transferring Owner and the transferee shall agree upon the percentage of the total Owner's Plant Assets of all of the Owners that is represented by the Owner's Plant Assets of the transferring Owner to be transferred to the transferee (assuming that the five pot lines at the Plant constitute one hundred percent (100%) of such total Owner's Plant Assets and that one pot line constitutes twenty percent (20%) of such total Owner's Plant Assets), and the remainder of the portion of the Interest to be transferred by the transferring Owner to the transferee shall consist of an undivided interest, as tenant in common, in an equal percentage in the Jointly-Owned Property and an equal percentage of the membership units of CAK. In the event of a transfer by an Owner of a portion of an Interest as provided for herein after the occurrence of the Reconstitution, the portion of the Interest so transferred shall consist of an undivided interest, as tenant in common, in the Plant Assets, in an equal percentage in all of such Plant Assets, together with an equal percentage of the membership units of CAK. 27 9.1.6 Minimum Interest. Except for the transfers involving all of an Owner's Interest or as a result of the application of Section 10.5, no transfer shall be permitted under this Owners Agreement if, as a result of such transfer, either the new Owner or the Transferring Owner would hold less than a twenty percent (20%) Interest in the Plant. Section 9.2 Voluntary Encumbrances. 9.2.1 Restrictions. An Owner (for purposes of this Section 9.2, the "Granting Owner") may agree to grant a mortgage or otherwise agree to grant a Lien on its Interest or any portion thereof, provided (a) the rights of the mortgagee or lienholder (for purposes of this Agreement, the "Secured Party") are expressly limited to the Interest of the Granting Owner (to the extent so encumbered) in such assets and shall not impair or otherwise affect title to the Interest of the non-granting Owner (including its transferees under this Article IX) or its right to any increase in the value of its Interest, and any rights in the encumbered Interest which the Secured Party may assert, acquire or transfer, whether through foreclosure or otherwise, shall in all events be subject to the non-granting Owner's rights under this Agreement (including without limitation the rights of the non-granting Owner under Section 2.3.2 and Articles IX and X), and (b) prior to the granting of any such Lien by a Granting Owner the non-granting Owner shall have approved in writing the form and substance of the provisions required under clause (a) and the validity and enforceability of the document in which such provisions are contained, and (c) the Granting Owner shall notify the non-granting Owner and the Operator in writing of the identity, address and contact information of the Secured Party and, promptly upon the occurrence thereof, the Granting Owner shall notify the non-granting Owner of the exercise of any rights with respect to the Lien by the Security Party (other than rights to access and/or information) and/or the release of the Lien. 9.2.2 Acknowledgment of Liens. (a) GAC acknowledges that NSA and its Affiliates are, as of the date hereof, granting a Lien on the Interest of NSA to secure in part the Notes (and may grant a Lien in connection with any refinancing thereof), and that GAC has reviewed and approved the form and substance of the mortgage and other documents and instruments evidencing such Lien and the validity and enforceability of the provisions setting forth the rights of GAC, as Owner hereunder, as incorporated therein, and that the grant of such Lien and the filing of such mortgage and other documents, in and of themselves, shall not give rise to any rights of GAC to acquire the Interest of NSA set forth in this Article IX, including without limitation under Section 9.3. 28 (b) The Owners acknowledge and agree that either Owner shall be entitled to grant a Lien on its Inventory or any portion thereof; provided however, that any such Lien shall be subject to the right of the non-granting Owner, if such Owner shall exercise its rights to use the Interest of a Defaulting Owner under Section 10.4.1, to use the Inventory of such Granting Owner or Defaulting Owner. The Operator shall be entitled to take such actions as may be required in connection with the enforcement of the rights of such Secured Party, provided that any increased costs incurred by the Operator in connection therewith shall not be Operating Costs but shall be chargeable to the Owner granting such Lien as a cost related to financing. 9.2.3 Condition Precedent to Enforcement of Voluntary Encumbrances. Prior to the exercise by a Secured Party of any foreclosure rights under any Lien granted by a Granting Owner on its Interest, the Secured Party shall give at least sixty (60) days' prior written notice to the other Owner of its intent to exercise such rights and the principal amount (and not any interest) secured by the Lien which is in default, and the other Owner shall have the right (but not the obligation) to acquire all or part of the Interest of the Granting Owner upon payment to the Granting Owner (without prejudice to the rights of the Secured Party in such proceeds) within that sixty (60) day period of the Fair Market Value of the Interest or part thereof being purchased. The Granting Owner shall take all necessary steps to ensure that the transfer of the Interest (or portion thereof as applicable) is free and clear of the Lien of the Secured Party. In the event that the other Owner shall have delivered a written notice to the Granting Owner of its intent to exercise the right granted pursuant to this Section 9.2.3 and shall have made payment of the amount provided for in the immediately preceding sentence, then the Granting Owner shall execute and deliver to the non-granting Owner instruments evidencing the transfer of its Interest (or if appropriate, portion of its Interest) to the non-granting Owner. The non-granting Owner's rights under this Section 9.2.3 are in addition to its rights under the provisions required under Section 9.2.1 and in addition to any claims for damages which such non-granting Owner may have against the Granting Owner. 9.2.4 Secured Party's Rights; Non-Granting Owners' Rights. If the non-granting Owner fails to exercise its right to purchase all or a part of the Granting Owner's Interest as provided in Section 9.2.3, the Secured Party shall have the right in the name and on behalf of the Granting Owner, to sell the Granting Owner's Interest or that part not acquired by the other Owner, subject in all events to the prohibition against partition provided for in Section 2.3.2 and the requirements of Sections 9.1.3 and 9.1.5, but not subject to the provisions of Sections 9.3.2(a), (b), (c) or (f) or 9.4. The transferee shall be subject to the provisions of Sections 9.3.2(d)(ii), (iii) and (iv) and 9.3.2(g). Section 9.3 Right of First Refusal. 9.3.1 Restrictions. Absent the express prior written consent of the other Owner and except for transfers permitted pursuant to Sections 9.2.3 and 9.4.1 and transfers to the other Owner pursuant to Section 10.5, no Owner shall offer to transfer, or transfer, all or any part of its Interest to any Person (other than as provided in Section 9.1.2) except as provided in this Section 9.3. 29 9.3.2 Right and Procedure. (a) An Owner that desires to transfer its Interest or a part of the Interest ("Transferring Owner") to a third Person, and has reached basic agreement with such third Person regarding the terms and conditions of the transfer, must give notice to the other Owner specifying in detail the price and other terms and conditions upon which the Transferring Owner proposes to sell its Interest or part thereof to the third Person, the percentage of such Interest being transferred and the name of the third Person. (b) Within sixty (60) days after such notice, the other Owner shall notify the Transferring Owner whether it desires to acquire, at the price and on the terms and conditions contained in the Transferring Owner's notice, the Transferring Owner's Interest or part thereof being offered. If the other Owner does not so notify the Transferring Owner it shall be deemed to have rejected the Transferring Owner's offer. (c) If the other Owner accepts the Transferring Owner's offer, the Transferring Owner and the other Owner shall be deemed to have contracted for the sale and purchase of the Transferring Owner's Interest or part thereof on the terms and conditions offered, and a closing of the transaction in accordance with the terms and conditions of the offer shall be made within ninety (90) days after the deemed acceptance. (d) If the other Owner does not elect to purchase the Transferring Owner's Interest or part thereof, the Transferring Owner during the one hundred eighty (180) days following the sixty (60) day period under clause (b) may transfer (on the same terms and conditions offered to the other Owner) its Interest or part thereof to the proposed transferee identified as provided in subsection (a) above (if applicable), provided that the Transferring Owner or the proposed transferee, as the case may be, shall deliver to the other Owner at such closing, as a condition to the transfer, executed originals (in form and substance reasonably satisfactory to the other Owner) of the following documents: (i) certificates of officers of each of the Transferring Owner and the transferee confirming the terms under which the Transferring Owner is transferring the Interest or part thereof to the transferee; (ii) if the transferee does not have a Tangible Net Worth at least equal to $200,000,000, it shall (i) provide to each other Owner and the Operator a guarantee, in the form of the Parent Guarantee attached hereto as Exhibit B-3, of an Affiliate of the proposed transferee or other corporation which has a Tangible Net Worth at least equal to $200,000,000, with Tangible Net Worth under this clause 9.3.2(d)(ii) to be evidenced by the most recent audited financial statement of the transferee or its guarantor, or by a written opinion of a nationally recognized independent accounting firm; or (ii) deliver to the other Owner an irrevocable letter of credit drawn on a U.S. bank holding a long 30 term rating not less than "A" or equivalent from a nationally recognized financial rating agency. Such letter of credit shall be in a form reasonably acceptable to the other Owner, shall name the Operator as beneficiary, shall be in an amount equal to one half of the Owner's Interest times the annual operating and capital budget then in effect in respect of the Plant, and shall have an expiry date not shorter than twelve (12) months, and a replacement letter of credit or Guarantee meeting the requirements of this Section 9.3.2(d)(ii) shall be delivered to the Operator no less than thirty (30) business days prior to the expiry of the then current letter of credit. (iii) the proposed transferee's written undertaking to be bound by all of the terms and conditions of this Agreement as an Owner; and (iv) such opinions of legal counsel to the proposed transferee and any guarantor as the other Owner shall reasonably require. (e) The Transferring Owner shall pay all costs of transfer of its Interest. (f) If the Transferring Owner fails to consummate the third party transfer within the one hundred eighty (180) day period referred to in Section 9.3.2(d), the first rights of the other Owner in the Transferring Owner's Interest shall be deemed to be revived and notice under clause (a) and compliance with the other terms of this Section 9.3 shall be required in respect of any transfer thereafter. (g) Following a transfer of an Interest or part thereof in accordance with the provisions of this Section 9.3, if at any time the Parent Guarantor providing a guarantee of the obligations of the transferee shall cease to have a Tangible Net Worth at least equal to $200,000,000, as evidenced by such Parent Guarantor's most recent unaudited quarterly financial statements, then the transferee Owner or such Parent Guarantor shall promptly notify the other Owner or Owners and shall deliver promptly to the other Owner or Owners an irrevocable standby letter of credit meeting the requirements of Section 9.3.2(d)(ii) and replacements thereof as required thereby. Section 9.4 Involuntary Transfers or Encumbrances. 9.4.1 Deemed Offer to Transfer. Except for transfers pursuant to Section 9.2.3, if the Interest (or any portion thereof) of an Owner is involuntarily transferred or encumbered as a result of judicial process, attachment, execution or judicial sale and such involuntary transfer or encumbrance is not set aside or discharged within sixty (60) days, then the Interest held by that Owner shall be deemed to have been offered for sale to the other Owner on the date the other Owner receives actual notice of the involuntary transfer or encumbrance. The other Owner shall have the option, exercisable before the earlier to occur of (i) the date on which the involuntary transfer or encumbrance is set aside or discharged, or (ii) the date which is sixty (60) days after such actual notice to it, to purchase all or, if the Reconstitution shall have occurred, such part as the other Owner shall determine, of the involuntarily transferred or encumbered Interest for a price equal to Fair Market Value thereof as determined pursuant to Section 9.4.2, payable in cash. The provisions of Section 9.3 shall not apply to any such involuntary transfer. 31 9.4.2 Fair Market Value. "Fair Market Value" shall mean for purposes of this Agreement the fair market value of the relevant Interest or portion thereof agreed upon by the purchasing Owner and the other Owner, a Secured Party and/or a trustee in bankruptcy, as the case may be (an "Interested Party"), subject to the proviso below, or as otherwise determined as provided in this Section 9.4.2. In the event that, within ten (10) days (i) after receipt by the Owner entitled to exercise a right to purchase pursuant to Section 9.2.3 or 9.4.1, of the notice provided for under the relevant Section, or (ii) delivery of notice by a non-defaulting Owner of an exercise of its rights pursuant to Section 10.5, as the case may be, the purchasing Owner and the Interested Party cannot agree upon the fair market value of the Interest or portion thereof to be transferred, then, within five (5) days after such ten (10) day period has expired, such Owner and Interested Party will select an independent appraiser, who will determine the then-current fair market value of the Interest or portion thereof. The Owners hereby agree that (x) any appraiser selected shall be an investment bank or other independent appraiser with expertise in the appraisal of aluminum reduction facilities and (y) the value of the Interest or portion thereof shall be calculated as (A) a value per Ton of production capacity, multiplied by (B) the rated production capacity, in Tons of Molten Metal per year, represented by the Interest or portion thereof to be transferred, provided that, in the case of an appraisal of the Interest or a portion thereof of NSA, the Fair Market Value determined for purposes of any transaction shall in no event be less than the amount determined using the applicable methodology set forth in the indenture entered into by Century with respect to the Notes (or such methodology as may be required by applicable law governing such indenture), so long as such indenture is in force. Such appraiser will determine the fair market value of the Interest or portion thereof within twenty-five (25) days following its selection. In the event that, within the five (5) day period provided for the parties to select an appraiser, the relevant parties are unable to agree upon an appraiser, each of them will within an additional five (5) days after expiration of such period select a professional designee and such designees together shall select an appraiser within five (5) days of their selection. In the event that, within the five (5) day period provided for the designees to select an appraiser, the designees are unable to agree upon an appraiser, each of the relevant parties will within an additional five (5) days after expiration of such period select an independent appraiser and such appraisers together will select a third independent appraiser meeting the criteria specified above, whose determination of the fair market value of the Interest or portion thereof will be final and binding on all parties. This third (3rd) appraiser will have thirty (30) days following its selection to determine the fair market value of the Interest or portion thereof. The costs and expenses of appraisal shall be borne by the Granting Owner or Defaulting Owner, as the case may be. In the event that an appraisal in the manner described above is not completed within the relevant sixty (60) day period provided for a purchasing Owner to purchase an Interest or portion thereof pursuant to Section 9.4.1 (but not Section 9.2.3 or 10.5.2(b)), then such period shall be extended as necessary for the completion of the appraisal, but not for a period longer than an additional thirty (30) days, and payment of the Fair Market Value as so determined shall be made by the purchasing Owner within ten (10) days of the final determination thereof. Section 9.5 Transfer of Ownership of an Owner. Each Owner shall remain, either directly or indirectly, wholly-owned by its respective parent which in the case of NSA shall be Century, and in the case of GAC shall be Glencore or, in the case of an Owner which acquired its Interest under this Article IX, by its ultimate parent company on the date of transfer of the Interest to that 32 Owner. Failure to maintain such ownership of an Owner without the prior written consent of the other Owner (which consent may be freely withheld) shall be deemed to be a default of that Owner under this Agreement and, in addition to any claims for damages which the other Owner may have against the defaulting Owner and its Parent Guarantor (if any), the other Owner may require that the defaulting Owner's Interest be sold and purchased in the manner provided for under Section 10.5. The restrictions on transfer of ownership of an Owner by its parent company set forth in this Section 9.5 shall not apply to a Secured Party which shall acquire ownership of an Interest through the enforcement of its rights under a Lien on such Interest (unless such Secured Party shall retain for its own interest, and not transfer, such Interest), but shall apply to any Person to which such Secured Party transfers such Interest. Section 9.6 Appointment of Operator Upon Transfer. In the event of a transfer by GAC to a non-Affiliate of GAC of all or part of its Interest in accordance with the provisions of this Article IX, NSA or an Affiliate of NSA shall have the right (but not the obligation), in its sole discretion, to terminate the appointment of CAK as Operator and to appoint an Affiliate of NSA as replacement Operator. In the event of a transfer of the Interest of NSA pursuant to a foreclosure on a voluntary Lien in accordance with Section 9.3.2, or an involuntary transfer as specified in Section 9.4, GAC or an Affiliate of GAC shall have the right but not the obligation, in its sole discretion, to terminate the appointment of CAK as Operator and to appoint a replacement Operator. In the event of the termination of the appointment of CAK as Operator in accordance with the first or second sentence of this Section 9.6, the appointment of a replacement Operator shall become effective upon the acceptance by the replacement Operator of such appointment. Section 9.7 Closings. The closings for any transfer of an Owner's Interest pursuant to Section 9.2.3, 9.3.2(c), 9.3.2(d), 9.4.1 or 10.5 shall take place at the principal office of the Operator or at such other location as the parties to the closing may mutually agree. The Transferring Owner shall deliver (i) the requisite instruments of conveyance, sale and assignment with respect to the Transferring Owner's Interest in the Owner's Plant Assets and in the Jointly-Owned Property as tenant in common, and (ii) all other documents as may be reasonably requested by any purchasing owner in order to confirm the Transferring Owner's title to and transfer of its Interest and the authority of its agent, officer or attorney to act in connection with each of the transfers referred to in clauses (i) and (ii) above. Article X DEFAULT Section 10.1 Events of Default. Each of the following shall constitute an "Event of Default" with respect to an Owner (the "Defaulting Owner") for purposes of this Article X: 10.1.1 the failure by that Owner to pay amounts due to the Operator or the other Owner under this Agreement within three (3) full business days (based on recipient's business days and its local banking hours) after notice by the Operator or such other Owner demanding such payment be made; 10.1.2 that Owner transfers or encumbers, or attempts to transfer or encumber, any of its Interest in violation of the terms of Sections 9.2 or 9.3; 33 10.1.3 any default by that Owner (as an owner in any material obligation under this Agreement (other than as described in clauses 10.1.1 or 10.1.2 above) which remains uncured for thirty (30) days after notice of such default from the other Owner; 10.1.4 the filing by that Owner, or any other Person which directly owns fifty-one percent (51%) or more of that Owner's shares of voting stock (that Owner's "Parent"), or (if different from the Parent) the Parent Guarantor of that Owner's obligations under this Agreement, of a voluntary petition in bankruptcy, or for reorganization, rehabilitation or dissolution or other proceeding analogous in purpose or effect; 10.1.5 the filing against that Owner or its Parent or (if different from the Parent) the Parent Guarantor of that Owner's obligations under this Agreement, by its creditors of a petition in bankruptcy or for reorganization, rehabilitation, involuntary liquidation or dissolution or other proceeding analogous in purpose or effect, which is not dismissed or stayed within sixty (60) days of filing; or 10.1.6 any act by that Owner or its Parent or (if different from the Parent) the Parent Guarantor of that Owner's obligations under this Agreement, which results in a default under Section 9.5. Section 10.2 Constitution of Owners Committee Upon Event of Default. Upon the occurrence of an Event of Default and until that Event of Default is cured, the Defaulting Owner shall lose its membership and voting rights on the Owners Committee, and the attendance of a Representative of the Defaulting Owner shall not be required to constitute a quorum for actions by the Owners Committee. Section 10.3 Notification of Secured Party; Right to Cure. Notwithstanding anything to the contrary set forth in this Article X, prior to the exercise of any remedies provided for herein by a non-defaulting Owner upon the occurrence of an Event of Default by a Defaulting Owner, such non-defaulting Owner shall have provided or caused to be provided, to any Secured Party of whose existence it has received written notice pursuant to Section 9.2.1(c) at its address provided in such notice, written notice of such Event of Default and a period of (a) five (5) days, in the case of an Event of Default which consists of a payment default or (b) thirty (30) days with respect an Event of Default which is not a payment default, shall have elapsed since the date of such notice during which the non-defaulting Owner has permitted the Secured Party the opportunity to cure the Event of Default. Section 10.4 Use of Defaulting Owner's Interest. 10.4.1 Right of Non-Defaulting Owner. (a) If an Event of Default is not cured within the applicable time period provided therefor after notice of default is given to the Defaulting Owner by the nondefaulting Owner of its intent to exercise its rights under this Section 10.4, the nondefaulting Owner may exercise the right to use the Defaulting Owner's Interest and perform the obligations of the Defaulting Owner in place of the Defaulting Owner, including using the Defaulting Owner's Alumina or supplying quantities of Alumina sufficient for the production of the Defaulting Owner's Basic Tonnage and Allocated Excess Tonnage. The nondefaulting Owner shall thereby become entitled to sell for the account of the Defaulting Owner all Molten Metal or Primary Aluminum to which the Defaulting Owner would otherwise be entitled. 34 (b) Proceeds received from such sales in excess of one hundred six percent (106%) of the total cost of producing the Defaulting Owner's share of Primary Aluminum, including without limitation the cost of Alumina, Operating Costs, Extras and freight in (for Alumina) and freight out (for Primary Aluminum) (collectively, for purposes of this Section 10.4 and Section 10.5, "Total Costs") shall be applied first to payment of any amounts owed by the Defaulting Owner to the non-defaulting Owner, then to payment of any amounts owed by the Defaulting Owner to the Operator, and the remainder of the excess above 106%, if any, shall be paid to the Defaulting Owner. The non-Defaulting Owner shall be entitled to retain the excess remaining from the one hundred six percent (106%) of Total Costs after payment of such costs, to defray its own expenses. 10.4.2 Non-Defaulting Owner's Costs, etc. The non-defaulting Owner which has elected to exercise its right to use the Defaulting Owner's capacity under this Section 10.4 shall have the right at any time to elect to treat the costs, loss or damage resulting to it from such use as a monetary default as provided in Section 10.7. It shall exercise such right by giving notice to the Defaulting Owner of the amount of expense it has incurred on behalf of the Defaulting Owner. Section 10.5 Option to Purchase Defaulting Owner's Interest. 10.5.1 Agreement on Liquidated Damages. (a) The Owners acknowledge that if a Defaulting Owner fails to cure an Event of Default within thirty (30) days of notice by the non-defaulting Owner of its intent to exercise its rights under this Section 10.5, it will be difficult to measure all of the damages resulting from such failure to cure. Therefore, the Owners agree that, in addition to the rights of the non-defaulting Owner provided for in Section 10.4.1, if an Event of Default is not cured within thirty (30) days after such notice to the Defaulting Owner, then, as reasonable liquidated damages, the Defaulting Owner shall be deemed to have offered its Interest for sale to the non-defaulting Owner, and the non-defaulting Owner shall be entitled to purchase the Interest of the Defaulting Owner, at the price and in the manner provided for in Section 10.5.2 below. (b) In the event that the non-defaulting Owner shall purchase part but not all of the Defaulting Owner's Interest pursuant to Section 10.5.1(a), and shall continue to exercise its rights provided for in Section 10.4.1 with respect to the remaining portion of the Interest retained by the Defaulting Owner, then at any time and from time to time thereafter, subject to Section 10.5.2(d) below, the non-defaulting Owner shall be entitled upon notice given thirty (30) days in advance, to purchase all or any part of the remaining portion of the Interest retained by the Defaulting Owner at the then current Fair Market Value thereof. 35 10.5.2 Exercise of Right to Purchase. In the event of a deemed offer of sale by a Defaulting Owner of its Interest pursuant to Section 10.5.1, the non-defaulting Owner shall be entitled to exercise its right to purchase as follows: (a) the non-defaulting Owner shall give notice of its intent to purchase the Interest or portion thereof within thirty (30) days of the time at which the offer to sell has been deemed to be made; (b) with respect to a purchase by GAC of the Interest of NSA, so long as the indenture entered into by Century with respect to the Notes and any registered notes for which such Notes may be exchanged is in force, payment shall be made in the manner and to the extent required under such indenture, including payment within sixty (60) days of the date on which the offer to sell was deemed to be made, but no later than the date of transfer of the Interest, of an amount in cash at least equal to seventy-five percent (75%) of the total purchase price, with the balance to be paid in accordance with the provisions of Section 10.5.2(c) below; and (c) the non-defaulting Owner shall be entitled to make payment of (i) the balance of the purchase price of the Interest or portion thereof after the payment required pursuant to paragraph (b) above, or (ii) in the event that the indenture referred to in such paragraph (b) is no longer in force, the total purchase price of the Interest or portion thereof which it has elected to purchase, in either case from fifty percent (50%) of the amount of Gross Profits as hereafter defined, if any, derived from the Interest of the Defaulting Owner during each calendar year and not from any other source. (d) Nothing in this Section 10.5 shall prohibit a Secured Party from transferring any Interest of a Defaulting Owner prior to the exercise of a right of purchase by the non-defaulting Owner, and the non-defaulting Owner shall have no rights under Section 10.2, 10.4 or 10.5 against the transferee with respect to the default by the Defaulting Owner, provided that the Secured Party shall have complied with Section 9.2.3 or 9.4.1, as applicable. 10.5.3 "Gross Profits"; "Market Price". For purposes of this Section 10.5: (a) "Gross Profits" means an amount, determined on a cumulative annual basis, with respect to Primary Aluminum produced by use of the relinquished Interest of the Defaulting Owner, equal to the excess, if any, of (i) the Market Price of Primary Aluminum determined on a daily basis over (ii) the Total Costs, determined by reference to billings from the Operator. If the Plant is operating at less than Rated Capacity, it shall be assumed for purposes of calculating "Gross Profits" that the relinquished Basic Tonnage is the operating capacity first reduced. (b) "Market Price" means the mid-point of the bid and asked prices for unalloyed ingot, New York Merchant Price (99.7%), as published in American Metal Market under the heading "AMM Closing Prices - Aluminum" or, if such publication ceases, an equivalent publication. Section 10.6 Attorney-in-Fact. Each Owner hereby irrevocably appoints the other Owner its attorney-in-fact to execute, file and record all instruments necessary to perfect or effectuate the provisions of this Article X during the continuance of an Event of Default. This power of attorney shall be deemed coupled with an interest. 36 Section 10.7 Monetary Defaults. If an Owner fails to make any payment required under this Agreement, the non-defaulting Owner may advance the amount of the defaulted payment on behalf of the Owner in default and treat the same, together with accrued interest, as a demand loan bearing interest from the date of the advance at the Interest Rate plus two percent (2%). Each Owner hereby grants to the other a lien upon its Interest and a security interest in its rights under this Agreement and in its Interest, and the proceeds therefrom, which shall be junior to any Lien granted in compliance with Section 9.2.2, to secure (a) any loan made hereunder, including interest thereon, which shall be in an amount no greater than is reasonably required in order to pay the Operating Costs attributable to the Defaulting Owner, and (b) reasonable attorneys fees and all other reasonable costs and expenses incurred in recovering the loan with interest and in enforcing such lien or security interest, or both. Section 10.8 Appointment of Operator. In addition to the other rights of a non-defaulting Owner specified in this Article X, in the event of a default by NSA which is not cured within thirty (30) days after notice of default is given to NSA by GAC of its intent to exercise its rights under this Section 10.8, GAC shall have the right to terminate the appointment of the Operator and to appoint a replacement Operator, provided that such replacement Operator shall enter into an agreement providing for its appointment on terms and conditions substantially similar to those applicable to the Operator provided for in this Agreement. Article XI COVENANTS Section 11.1 Inspection.

Section 11.2 Liens. Except as may be permitted pursuant to Sections 7.3, 9.2, 10.7 and 11.6, none of the Owners or the Operator shall cause any Liens (other than tax Liens for taxes not past due) to be created or to exist upon the Plant, any Owner's Plant Assets or any Jointly-Owned Property. Each Owner shall notify the other Owner and the Operator or the Operator shall notify the Owners Committee promptly after discovery of the creation of any Liens on such property, and shall discharge forthwith all Liens not so permitted for which it or its employees, agents or contractors are responsible.

Each of the Owners and the Operator shall maintain full corporate power and authority to own, in the case of an Owner, its Interests and to perform its obligations under this Agreement, and shall promptly obtain any consent or approval of or license or permission from any governmental authority which may be required for the performance of such obligations. Section 11.6 Easements. Each Owner shall grant to the other Owner non-exclusive rights of way and easements on, over, through, under and across the real estate comprising a part of its Owner's Plant Assets and such rights of access and use of such Owner's Plant Assets and the other assets comprising its Interest as may be necessary for the operation by the other Owner of the assets comprising such other Owner's Interest.
