7.10    Non-Competition and Non-Interference.

(a)Non-Competition. For a period of 2 years from and after the Closing Date, without the prior written consent of Purchaser, Seller will not, and will cause its Affiliates not to, engage directly or indirectly in the manufacturing or production in the United States of the Products produced by the Facility as of the Closing (a “Competing Business”). Notwithstanding anything to the contrary in this Section 7.10(a) and without implication that the following activities otherwise would be subject to the provisions of this Section 7.10(a), nothing in this Agreement shall preclude, prohibit or restrict the Seller or any of its Affiliates

from (i) engaging in a Competing Business that has been acquired by Seller or any of its then Affiliates as a result of a business transaction whereby the Competing Business accounts for less than 20% of the revenues of the acquired business, (ii) making investments in Persons engaging in a Competing Business, in an investment fund or other investment vehicle or by any employee benefit plan or trust of Seller or its then Affiliates, provided that each such investment is an investment where Seller or such Affiliates (A) does not have the right to designate a majority of the members of the board of directors or similar body of such entity or direct the operation or management of any such entity, (B) is not a participant with any other Person in any group with such intention or right, and (C) owns less than 10% of the outstanding voting securities (including convertible securities) of such entity, (iii) purchasing from a Competing Business products for resale to its customers, or (iv) providing assistance to Purchaser in accordance with the terms of this Agreement or the Transition Services Agreement.

(b)Non-Solicitation of Employees. (i) For a period of 3 years from and after the Closing Date, without the prior written consent of Purchaser, Seller will not, and will cause its Affiliates not to, directly or indirectly solicit any Transferring Employee as an employee, independent contractor, or consultant or induce or attempt to induce any such Transferring Employee to terminate his or her employment with Purchaser by resignation, retirement or otherwise and (ii) for a period of 1 year from and after the Closing Date, without the prior written consent of Purchaser, Seller will not, and will cause its Affiliates not to, directly or indirectly, hire any Transferring Employee as an employee, independent contractor or consultant; provided that the foregoing shall not restrict general solicitations of employment through advertisements or other means that are not directed specifically at any Transferring Employee.

(c)Reasonableness of Restrictions. Seller and Purchaser each acknowledges that the time period, territory and scope of the activities proscribed in Sections 7.10(a) and 7.10(b) describe the reasonable limitation on the time and scope of activities necessary to protect Purchaser in the exploitation of its rights hereunder and under the Ancillary Agreements. Each acknowledges and agrees that monetary damages cannot compensate the other and its Affiliates in the event of a violation of any of the foregoing covenants. Accordingly, Seller agrees that in the event of a violation or breach of any covenant set forth in Section 7.10(a) or 7.10(b), Purchaser may institute any action or proceeding to enforce such covenant at law or in equity, including injunctive relief, and Purchaser shall be entitled to recover all costs and attorneys' fees incurred by it in connection with any successful action or proceeding to enforce such covenant. In the event that there shall be any violation of any covenant set forth in Section 7.10(a) or 7.10(b), then the applicable time limitation thereof shall be extended for a period of time equal to the period of time during which such violation continues; and in the event Purchaser is required to seek relief from such violation in any court, board of arbitration or other tribunal, then the covenant shall be extended for a period of time equal to the pendency of any such proceedings, including all appeals.

(d)Reformation. If any court of competent jurisdiction in a final nonappealable judgment determines that the time period, territory and scope of the activities proscribed in Section 7.10(a) or 7.10(b) is unreasonable, arbitrary or against public policy, then the maximum time period, territory and scope or other relevant feature which is determined by such court to be reasonable, not arbitrary and not against public policy shall be enforced against Seller.

7.11    Use of Names and Domain Names. Except as otherwise expressly set forth in this Section 7.11, Purchaser shall ensure that, on or prior to the 30th day following the Closing Date, the Facility ceases the use of the names and/or logos “Alcan,” “Rio Tinto,” and “Rio Tinto Alcan” or any other name and/or logo that is substantially the same or likely to be confused with the same (collectively, the “Names”); provided, however, for the avoidance of doubt, all right, title, and interest of Seller or any Affiliate of Seller in the name “Sebree” shall be assigned to Purchaser. To the extent that any of the Names or related trademarks appear, as of the Closing Date, on any stationery, signage, invoices, receipts, promotional materials, packaging materials, websites or similar commercial materials of the Facility (collectively, “Marked Materials”) or any inventory of the Facility at Closing, Purchaser may use such Marked Materials and sell such inventory from and after the Closing Date until the earlier of (a) with respect to each type of Marked Material enumerated above, the dates on which Purchaser has produced new stationery, signage, invoices, receipts, promotional

materials, packaging materials or other such commercial materials or have modified such websites, as the case may be, or have sold such inventory, and (b) with respect to each type of Marked Material enumerated above (other than inventory, it being understood and agreed that Purchaser shall be under no obligation to change, alter or cease the use of such markings on inventory), as soon as reasonably practicable but in any event no later than 120 days after the Closing Date. Purchaser shall use its commercially reasonable efforts to produce and use new stationery, signage, invoices, receipts, promotional materials, packaging materials and similar commercial materials, and to modify its websites, as soon as practicable. In addition, Seller shall cause any active domain names Related to the Facility to be redirected to a URL identified by Purchaser for a period of 120 days after the Closing Date. At Purchaser's election and as part of such redirection, Seller shall cause to be posted a web page (a) announcing the redirection, (b) making web visitors aware of the identity of Purchaser's URL, and (c) informing the web visitor that they will be redirected to Purchaser's URL within 10 seconds. Notwithstanding the foregoing, Purchaser shall not be obligated to change the Names or related trademarks on Marked Materials in the hands of dealers, distributors and customers at the time of the expiration of the time period set forth in this Section 7.11.

7.12    Books and Records.

(a)Retention by Purchaser. Seller shall have the right to retain copies of all books and records included in the Purchased Assets. Notwithstanding, the foregoing, Purchaser shall make the same reasonably available on and after the Closing Date for inspection and copying by Seller at Seller's expense during normal business hours of Purchaser, upon reasonable request and upon reasonable notice. No such books and records shall be destroyed by Purchaser, except in accordance with Purchaser's standard document retention policies and practice, for a period of at least 7 years after the Closing Date (or until all pending claims hereunder are resolved, if any such claim is pending as of the end of such 7 year period) without first advising Seller in writing and giving Seller a reasonable opportunity to obtain possession thereof.

(b)Retention by Seller. Seller shall retain all books and records and other documents pertaining in any way to Seller and/or the Facility (to the extent not included in the Purchased Assets) in existence on the Closing Date and to make the same reasonably available on and after the Closing Date for inspection and copying by Purchaser, at Purchaser's expense during the normal business hours of Seller, upon reasonable request and upon reasonable notice. No such books, records or documents shall be destroyed by Seller or any of its Affiliates, except in accordance with Seller's standard document retention policies and practice, for a period of at least 7 years after the Closing Date (or until all pending claims hereunder are resolved, if any such claim is pending as of the end of such 7 year period) without first advising Purchaser in writing and giving Purchaser a reasonable opportunity to obtain possession thereof.

(c)Post-Closing Confidentiality. From and after the Closing:

(i)Seller acknowledges that (A) during the course of its ownership of the Purchased Assets and its operation of the Facility, it has generated and had access to confidential information relating to financial performance, employees, suppliers, equipment, designs, drawings, programs, strategies, analyses, profit margins, sales, methods of operation, plans, products, technologies, materials, trade secrets, strategies, and prospects that is unique, specific, and related solely and exclusively to the Business, the Purchased Assets, and the Facility that is not known by or available to the public (collectively, “Confidential Information”) and (B) the unauthorized use or disclosure of any such Confidential Information at any time may constitute unfair competition with Purchaser and would deprive Purchaser of the benefits of this Agreement and the Ancillary Agreements and the transactions contemplated hereby and thereby. Accordingly, from and after the Closing, Seller shall (and shall cause its Affiliates and its and their respective Representatives to) hold in confidence such Confidential Information and will not, directly or indirectly, disclose, publish, or otherwise make available any such Confidential Information to the public or to any Person or use any of the Confidential Information for its own benefit or for the benefit of any other Person, other than Purchaser and its Affiliates.

(ii)Effective upon the Closing, the Confidentiality Agreement shall terminate with respect to information relating to the Purchased Assets, Assumed Liabilities and otherwise Related to the Facility.

7.13    Notices and Consents.

(a)Providing Notices. Subject to Section 7.13(b), prior to the Closing, Seller shall use its commercially reasonable efforts to give all notices required to be given by Seller and to obtain all Consents of any third parties (including any Governmental Entity) necessary to consummate the transactions contemplated by this Agreement. Purchaser shall cooperate with Seller in obtaining such Consents; provided, however, that neither Purchaser nor any of its Affiliates shall be required to pay any amounts or grant any material accommodations (financial or otherwise) in connection with obtaining any Consent. Seller shall provide to Purchaser copies of any such written Consent promptly after it has been obtained.

(b)Power Contract Consent. Notwithstanding anything herein to the contrary, Purchaser shall use its commercially reasonable efforts to cause the condition set forth in Section 6.02(d) to be satisfied. Seller shall, and shall cause its Affiliates and its and their respective Representatives to, cooperate with and use its commercially reasonable efforts to assist Purchaser in satisfying such condition; provided, however, that (i) neither Purchaser or any of its Affiliates nor Seller or any of its Affiliates shall be required to pay any amounts or grant any material accommodations (financial or otherwise) in connection with obtaining any Consent to the assignment of the Power Contract and (ii) without the express written consent of Purchaser, neither Seller nor any of its Affiliates or Representatives shall take any action, including entering into any negotiations or holding any discussions with Kenergy Corp. or Big Rivers Electric Corporation or any of their respective Affiliates or Representatives, with respect to the Power Contract or otherwise relating to obtaining any required Consent thereunder. Notwithstanding the foregoing, Seller and its Affiliates shall have the right to discuss with Kenergy Corp. and Big Rivers Electric Corporation matters relating to the day to day operations and electric service to the Facility under the existing Power Contract.

(c)Cooperation. From the date hereof until the Closing, (i) each of Purchaser and Seller shall use commercially reasonable efforts to resolve any objections as may be asserted by any Governmental Authority with respect to the transactions contemplated by this Agreement, and (ii) Seller shall use commercially reasonable efforts, and Purchaser shall cooperate with Seller, to contest and resist any legal proceeding instituted, or threatened to be instituted, by any Governmental Authority challenging the transactions contemplated by this Agreement as violative of any Law and to have vacated, lifted, reversed or overturned any order, injunction, judgment, decree or ruling, whether temporary, preliminary or permanent, that prohibits or prevents the consummation of the transactions contemplated by this Agreement, including by pursuing all available avenues of administrative and judicial appeal. Notwithstanding anything to the contrary provided herein, (i) no Party will be required to pay any consideration (except filing and application fees) to any other Person from whom any such consents, approvals or authorizations are requested, and (ii) neither Purchaser nor any of its Affiliates shall be required, in connection with the matters covered by this Section 7.13, to (A) commence Litigation (as opposed to defend Litigation), (B) hold separate (including by trust or otherwise) or divest any of its or its Affiliates' businesses, product lines or assets, or any of the Purchased Assets, (C) agree to any limitation on the operation or conduct of the Business, or (D) waive any of the conditions to this Agreement set forth in Section 6.01.

(d)Notice of Developments. Each Party shall give prompt written notice to the other Party of any statement or information contained in such notifying Party's representations and warranties (or Schedules thereto) that is incomplete or inaccurate. During the period between the date of this Agreement and the date that is 3 Business Days prior to the Closing, subject to Purchaser's rights under Section 6.04, Seller shall be entitled to deliver to Purchaser, no later than the 3rd Business Day prior to the Closing, a single update (but not more than one update) to the Seller Disclosure Schedules to the extent information contained therein becomes untrue or incomplete or inaccurate after the date hereof due to events or circumstances first arising or occurring after the date hereof. Subject to Purchaser's rights under Section 6.04, such update shall be deemed to supplement the Seller Disclosure Schedules and accordingly cure

any breach of any representation or warranty of Seller hereunder, but only for purposes of determining whether the conditions in Section 6.01(a) have been satisfied. Such update shall not be deemed to supplement the Seller Disclosure Schedules, to otherwise cure any breach of any representation or warranty of Seller hereunder or to affect Purchaser's right to indemnification pursuant to Article 9.

7.14    Bulk Sales Laws. Each Party hereby waives compliance by the Parties with the provisions of the "bulk sales," "bulk transfer" and similar Laws set forth in Article 6 of the Uniform Commercial Code as it is in effect in the states where the Purchased Assets are located and all other similar Laws of any Government Authority other than bulk-transfer tax notice provisions.

7.15    Real Property Matters.

(a)Conveyance of Fee Simple Title in Real Property. Seller shall convey to Purchaser, at the Closing, by special or limited warranty deeds, in customary form and conforming to the Real Estate Deed, title in fee simple to the Real Property subject only to Permitted Liens and such additional title and survey matters for which Seller is able to obtain affirmative title coverage for the benefit of Purchaser as contemplated by Section 7.15(e).

(b)Title Commitments and Surveys.     Purchaser has ordered or intends to order (i) title commitments for the Real Property (the “Title Commitments”), from a reputable, nationally known, title company (the “Title Company”) and ALTA land title surveys for the Real Property (the “Surveys”) from reputable survey companies. Seller shall use its commercially reasonable efforts to provide the Title Company and the surveyor(s) with information and assistance to permit it to prepare and issue the Title Commitments and the Surveys. Except as provided in this Section 7.15, all costs and expenses associated with obtaining the Title Commitments, copies of documents creating exceptions to title listed in the Title Commitments, and the Surveys shall be borne equally by Seller and Purchaser.

(c)Zoning Letters. Prior to the Closing, Purchaser may obtain a zoning letter or report for the Real Property certifying that the Real Property is in compliance with all applicable zoning laws and ordinances and that the conduct of the Business at the Real Property is a conforming use of the Real Property (collectively, the “Zoning Letters”). Seller shall use its commercially reasonable efforts to provide assistance to permit Purchaser to obtain the Zoning Letters.

(d)Title Exceptions. If the Title Commitments, the Surveys or the Zoning Letters reveal any material title exceptions that do not constitute Permitted Liens (such exceptions, “Unpermitted Exceptions”), then Seller shall either (i) cause such Unpermitted Exceptions to be removed or cured, or (ii) cause the Title Company, at the Seller's sole expense, to provide affirmative title insurance coverage over such Unpermitted Exceptions in connection with the issuance of the Title Policies. If Seller elects to obtain, and the Title Company agrees to provide, affirmative title insurance from the Title Company with respect to any Unpermitted Exceptions, then any Losses incurred by Purchaser with respect to such Unpermitted Exceptions shall not be subject to the indemnification obligations of Seller under Section 9.01 of this Agreement and Purchaser's sole recourse shall be to the Title Company and the Title Policies with respect to those Unpermitted Exceptions for which affirmative title insurance was provided by the Title Company.

(e)Title Policies.     At the Closing, Purchaser intends to obtain from the Title Company ALTA form owner's policies of title insurance insuring in Purchaser an owner's interest in the Real Property free and clear of all Liens (other than the Permitted Liens) and containing such endorsements as Purchaser may reasonably request in an amount equal to the value of the Real Property as reasonably determined by Purchaser (the “Title Policies”). All costs and premiums of the Title Policies, any endorsements that Purchaser may reasonably request in connection with the Title Policies, including extended coverage over the general or standard exceptions, survey endorsements, contiguity endorsements (if applicable), subdivision endorsements, zoning 3.1 endorsements (or equivalent), access endorsements and tax parcel endorsements, shall be borne equally by Seller and Purchaser. In connection with the issuance of the Title Policies, Seller shall furnish such customary affidavits, indemnities or documents as are reasonably

requested by the Title Company or that may be required by the Title Company to remove the standard pre-printed exceptions that may be removed upon provision of an affidavit and/or indemnity to the Title Company.

(f)No Merger of Representations and Warranties.    The Parties agree that the representations and warranties regarding the Real Property will not merge with or into the Real Estate Deed to be delivered by Seller pursuant to this Section 7.15. For the avoidance of doubt, Purchaser agrees that it is accepting title to the Real Property subject to all Permitted Liens (including the permitted exceptions listed on the Real Estate Deed), whether or not such Permitted Liens are listed or described on such Real Estate Deed.

(g)No Condition. For the avoidance of doubt, and notwithstanding anything to the contrary contained in this Section 7.15, Purchaser's obtaining the Surveys and Zoning Letters shall not be a condition to Purchaser's obligation to effect the Closing and consummate the transactions contemplated hereby.

(h)Excess Real Property. The Parties agree that the land north of the road known as “Moss Moss Road” and marked in black on the map attached hereto as Schedule 7.15(h) sets forth the demarcation of that portion of the Real Property which shall be deemed “Excess Real Property”. Following the Closing, the Parties shall cooperate and take such actions as may be necessary to finally determine the legal description of the Excess Real Property. All costs and expenses attributable to the determination of such legal description shall be borne equally by Purchaser and Seller. Following the Closing, in the event Purchaser sells or otherwise transfers to an un-Affiliated third party all or a portion of the Excess Real Property, on terms acceptable to Purchaser in its sole discretion, then Purchaser shall deliver or cause to be delivered to Seller 50% of the Net Proceeds of such sale or transfer. For purposes of this Agreement, “Net Proceeds” means the proceeds payable as consideration by an un-Affiliated third party for the sale or transfer by Purchaser of all or a portion of the Excess Real Property, net of all costs and expenses incurred by Purchaser or its Affiliates with respect to (i) effecting such sale or transfer, including any and all Transfer Taxes and other Taxes payable with respect thereto, or (ii) Purchaser's ownership, operation and management of the Excess Real Property from and after the Closing until the date of such sale or transfer, including all insurance, maintenance, security and other operating costs, including all Taxes paid or payable in connection with the Excess Real Property. Purchaser may, in its sole discretion, require that easements or other residual property rights for the benefit of the Facility and the Real Property that is not the Excess Real Property be retained by Purchaser as a condition to consummation of any sale or transfer of all or a portion of the Excess Real Property to an un-Affiliated third party, in which case Seller will have no rights associated with any such easements or residual property rights. Except with respect to the allocation of Net Proceeds pursuant to the terms of this Section 7.15(h), nothing herein shall prevent Purchaser, its Affiliates or its and their respective Representatives from acting, or refraining from acting, in the best interests of Purchaser or its Affiliates, considering only such factors as the Purchaser, its Affiliates or such Representatives choose to consider. Notwithstanding anything herein to the contrary, in no event will (i) Seller be entitled to any proceeds in connection with a transaction or series of related transactions that involves the sale or transfer by Purchaser of all or substantially all of the Real Property (including the Excess Real Property) and the Facility as a going concern, (ii) Purchaser have any obligation to sell or otherwise transfer the Excess Real Property, (iii) Purchaser or any of its Affiliates or its or their respective Representatives have any fiduciary or other duties to Seller or its Affiliates in connection with the Excess Real Property and this Section 7.15(h), or (iv) Section 7.15(h) be deemed to create any partnership or joint venture between Purchaser and Seller. Seller shall be entitled to, at Seller's sole cost and expense, record a memorandum, in form and substance reasonably satisfactory to Purchaser, in the Office of the Clerk of Henderson County, Kentucky, referencing Seller's rights under this Section 7.15(h); provided that prior to receiving any portion of any Net Proceeds, Seller shall file a release of any such memorandum in form and substance reasonably satisfactory to Purchaser.

7.16    Location of Assets. Seller shall cause all of the Purchased Assets, including original copies of all Assumed Contracts, to be located at the time of the Closing at the Facility.

7.17    Casualty; Condemnation.

(a)In the event that, between the date hereof and the Closing, the Facility or Purchased Assets are subject to damage or destruction resulting in ether (i) repair costs in excess of $5,000,000 or (ii) a reduction in the Facility's output of 10% or more over any period (in each case, a “Casualty”), or condemnation or partial condemnation by a Governmental Authority (a “Condemnation”), Seller shall give notice to Purchaser, as promptly as practicable upon becoming aware thereof, and Purchaser shall have the right to either (i) terminate this Agreement in which event the parties shall have no further obligations to each other except as otherwise set forth in Section 6.07, or (ii) proceed to the Closing, in which case (A) all proceeds from any insurance claims, condemnation awards, compensation or other reimbursements relating to such Casualty or Condemnation received by Seller, whether before, at or after the Closing, shall be paid over to Purchaser at the Closing (or promptly after Seller's receipt thereof if Seller receives such amounts after the Closing), and (B) if such Casualty is not covered under Seller's insurance policies, Seller shall pay to Purchaser an amount reasonably sufficient to allow Purchaser to repair, replace and restore the items subject to such Casualty to pre-damage condition.

(b)Any party receiving a notice of Casualty or Condemnation shall notify the other party to this Agreement in accordance with Section 10.06. Nothing in this Section 7.17 shall be deemed to limit the rights of Purchaser or Seller under Article 9.

7.18    Environmental Matters.

(a)From and after the date hereof, Seller shall not enter into any agreement with the EPA, including any agreement to resolve or settle the EPA NESHAP Claim, that would (i) impose production limitations on the Facility or any use limitation on any of the Purchased Assets, (ii) result in the incurrence of capital expenditures that would be binding on Purchaser following the Closing or that will not be paid by Seller, (iii) result in any business interruption or reduction at the Facility, or (iv) impose any limit on the future ability to increase production output to the Facility's permitted capacity.

(b)From and after the Closing, Purchaser shall not conduct any “Phase II environmental site assessments (ESAs)” (as that term is described in the ASTM E 1903 97 Standard Guide for Environmental Site Assessments) or any other invasive investigation, sampling or monitoring of environmental media at the Real Property unless (i) required by applicable Environmental Law or Law (including any such requirement of Environmental Law or Law relating to any maintenance, repair, renovation or expansion activities); (ii) required or requested by any proceeding, Environmental Permit, judgment, Governmental Authority or Third-Party Claim; (iii) required or requested by a lender, financier or insurance carrier or broker (for the purposes of, or relating to, financing or obtaining insurance) or by a potential purchaser in connection with the direct or indirect sale, lease or other disposition of all or part of the Real Property, the Facility or the Business; (iv) conducted pursuant to a program of a Governmental Authority enacted pursuant to Environmental Law applicable to the operation of the Business, the Facility, the Purchased Assets, or the Real Property which is deemed a self-implementing or “voluntary” program to address or remediate the Release of Hazardous Materials in order to avoid or mitigate liability under Environmental Law, (v) reasonably determined by Purchaser to be necessary for the protection of human safety or health or the environment, or (vi) in connection with activities undertaken in the ordinary course of business. During the 10 year period immediately following the Closing Date, prior to Purchaser conducting any “Phase II environmental site assessments (ESAs)” (as that term is described in the ASTM E 1903 97 Standard Guide for Environmental Site Assessments) or any other invasive investigation, sampling or monitoring of environmental media at the Real Property permitted under this Section 7.18(b), Purchaser shall (w) give notice to Seller, (x) confer with Seller and Seller's representatives, (y) permit Seller and its Representatives to participate in the planning and implementation of the procedures, and (z) provide copies of all resulting reports and other related information reasonably requested by Seller. Purchaser and Seller shall execute and deliver such confidentiality, joint-defense, or other agreements as may be necessary and desirable to allow the participation of Seller and its representatives. Notwithstanding anything herein to the contrary, no failure by Purchaser or its representatives or Affiliates to comply with the provisions of this Section 7.18(b) shall affect any rights a

Purchaser Indemnitee may have to indemnification pursuant to Article 9 unless (and then only to the extent that) Seller can demonstrate that it has been prejudiced by such failure to comply.

7.19    Post-Closing Collections and Payments. From and after the Closing, (a) Purchaser will (i) remit to Seller any payment Purchaser or any of Purchaser's Affiliates receives or collects on any note or receivable that constitutes an Excluded Asset and (ii) reimburse Seller for any payment Seller or any of Seller's Affiliates makes to a third-party in payment of an Assumed Liability and (b) Seller will (i) remit to Purchaser any payment Seller or any of Seller's Affiliates receives or collects on any note or receivable that constitutes a Purchased Asset or that otherwise relates to the operation of the Facility or the Business from and after the Closing and (ii) reimburse Purchaser for any payment Purchaser or any of Purchaser's Affiliates makes to a third-party in payment of a Retained Liability. Each Party will provide the other Party with reasonable detail regarding any such payments. Any remittance or reimbursement required to be made by a Party pursuant to this Section 7.19 will be (a) made net of any outstanding remittance or reimbursement owed to such Party pursuant to this Section 7.19 and (b) made promptly, and in any event not later than the 15th day of the calendar month immediately following the calendar month in which the payment giving rise to such remittance or reimbursement, as applicable, was received or made.

7.20    Audited 2012 Financial Statements. As soon as practicable following the date of this Agreement, and in any event prior to the Closing, Seller shall deliver to Purchaser the Audited 2012 Financial Statements. Purchaser shall reimburse Seller in an amount equal to 50% of its documented third-party out-of-pocket costs incurred by Seller or its Affiliates in connection with the preparation of the Audited 2012 Financial Statements and the various carve-out statements referenced in Section 7.04(a)(ii); provided, however, that in no event will Purchaser reimburse Seller for more than $250,000 of such costs. Without limiting the foregoing, in the event the Audited 2012 Financial Statements are not delivered to Purchaser on or prior to May 15, 2013, then Seller will promptly (and in any event no later than May 16, 2013) pay or cause to be paid to Purchaser, pursuant to wire instructions to be provided to Seller by Purchaser, an amount in cash equal to $1 million.

7.21    Alumina Contract. Notwithstanding anything in the Alumina Contract or the Confidentiality Agreement, Seller shall permit Purchaser to negotiate with Noranda for an alumina sales agreement with Noranda with respect to the supply of alumina to the Facility on terms acceptable to Purchaser. If Purchaser does not enter into such a new alumina sales agreement for the Facility prior to Closing, and subject to Purchaser's rights under Section 6.04(b), from and after the Closing until the Alumina Contract is terminated in accordance with its terms (provided that neither Seller nor any of its Affiliates has affirmatively taken any action, or intentionally failed to take any action, to cause such termination without the prior written consent of Purchaser), upon the request of Purchaser, (a) Seller shall, and shall cause RTA to, act under the Alumina Contract as Purchaser directs (and only as Purchaser directs, provided such direction by Purchaser does not cause RTA to be in breach of the Alumina Contract), (b) Seller shall cause RTA to resell to Purchaser any alumina obtained by RTA under the Alumina Contract pursuant to Purchaser's instructions in the same condition and at the same cost and pursuant to the same terms that such alumina was obtained by RTA from Noranda, and shall cause the alumina to be delivered by Noranda to Purchaser at the Facility, (c) Seller shall not, and shall cause RTA not to, cancel, terminate or otherwise modify or waive the Alumina Contract without Purchaser's express written consent, (d) Seller shall, or shall cause RTA to, enforce (or not enforce) the provisions of the Alumina Contract as Purchaser directs (and only as Purchaser directs, provided such direction by Purchaser does not cause RTA to be in breach of the Alumina Contract) and (e) without the express written consent of Purchaser, neither Seller nor any of its Affiliates or Representatives shall take any action, including entering into any negotiations or holding any discussions with Noranda with respect to the Alumina Contract. For the avoidance of doubt, and provided Seller complies with its obligations under this Section 7.21, Seller shall have no liability to Purchaser for (i) any failure of Noranda to comply with the terms of the Alumina Contract, or (ii) any failure by Purchaser to reach agreement with Noranda or any other Person for the supply of alumina to the Facility.

8.01    Assumption of Union Agreement. Subject to applicable Law, the completion of any legally or contractually required bargaining between Purchaser and the Union on terms reasonably satisfactory to Purchaser, and the receipt of any necessary Consents, upon consummation of the Closing, Purchaser shall become signatory to and shall assume all obligations under the Union Agreement. Subject to the terms thereof, Purchaser shall recognize the Union as the collective bargaining representative of the Transferring Union Employees at the Facility.

8.02    Employment of Union Employees. From and after the Closing, Purchaser shall employ or continue the employment of each Employee who is, as of immediately prior to the Closing, subject to the Union Agreement and (a) actively at work in connection with the Facility, (b) receiving benefits under Seller's Weekly Accident & Sickness Plan, or on workers' compensation, in connection with the Facility, (c) on a leave of absence approved by Seller in connection with the Facility or (d) on layoff with recall rights as provided under the Union Agreement (collectively, the “Union Employees”), in compliance with the Union Agreement, unless such Union Employee voluntarily terminates his or her employment with Purchaser. Notwithstanding the foregoing, nothing in this Agreement shall be construed as requiring Purchaser to recall any Union Employee on layoff with recall rights unless and until an available position exists with respect to such Union Employee in accordance with the terms of the Union Agreement. Union Employees who are employed by or whose employment continues with Purchaser as of the Closing Date shall be referred to as “Transferring Union Employees.” From and after the Closing, Purchaser shall continue the employment of each Transferring Union Employee pursuant to the terms of the Union Agreement, subject to Purchaser's rights to terminate such employment pursuant thereto.

8.03    Employment of Non-Union Employees. Effective as of the Closing, except as set forth on Schedule 8.03, Purchaser shall make offers of employment to each Employee who is, as of immediately prior to the Closing, not subject to the Union Agreement, and who is (a) actively at work in connection with the Facility, (b) receiving short term disability benefits or on workers' compensation, or (c) not actively at work due to vacation, holiday, illness, injury (other than an Employee on long term disability) or jury duty (collectively, all of the foregoing individuals, the “Nonunion Employees”). Nonunion Employees who accept such offers of employment as of the Closing Date shall be referred to as “Transferring Nonunion Employees” and, together with the Transferring Union Employees, collectively the “Transferring Employees.” Notwithstanding anything in the foregoing in this Section 8.03, but subject to the further obligations of Purchaser under this Article 8 with respect to the provision of benefits, nothing in this Agreement shall, from and after the Closing Date, impose on Purchaser any obligation to retain any Transferring Nonunion Employee in its employment.

8.04    Disability.

(a)Seller shall be solely liable and responsible for providing all accident and sickness benefits and short term disability benefits relating to claims incurred by Employees prior to the Closing. Subject only to the obligations of the Provider under the Transition Services Agreement, Purchaser shall be solely liable and responsible for providing all accident and sickness benefits and short term disability benefits relating to claims incurred by Transferring Employees from and after the Closing.

(b)For the avoidance of doubt, Purchaser shall be under no obligation to offer employment to Employees who are receiving benefits under Seller's long term disability plan as of the Closing. Seller shall be solely liable and responsible for providing long term disability benefits to any Transferring Employee relating to claims incurred prior to the Closing and to any claims arising from a claim for accident and sickness benefits or short term disability benefits for which Seller retains liability for pursuant to Section 8.04(a). Subject only to the obligations of the Provider under the Transition Services Agreement, Purchaser shall be solely liable and responsible for providing long term disability benefits to any Transferring Employees relating to claims incurred from and after the Closing to the extent Seller is not liable for such claim pursuant to the immediately preceding sentence.

(c)For purposes of this Section 8.04, a claim shall be deemed "incurred" on the date that the illness, injury or disability that gives rise to the claim occurs, without regard to the time the claim for benefits was actually filed with the applicable benefit plan or program.

8.05    Welfare Plans. Subject to Section 8.04, Seller shall, and shall cause the Business Benefit Plans that are welfare benefits plans within the meaning of Section 3(1) of ERISA (“Seller's Welfare Plans”) to, be liable for all claims incurred with respect to Transferring Employees and their spouses and dependents at or prior to the Closing. Subject only to the obligations of the Provider under the Transition Services Agreement, the plans sponsored by Purchaser or its Affiliates that are welfare benefit plans within the meaning of Section 3(1) of ERISA (“Purchaser's Welfare Plans”) shall provide coverage and benefits for all Transferring Employees and their respective eligible spouses and dependents effective on and after the Closing Date. Subject to Section 8.04 and the Transition Services Agreement, Purchaser and Purchaser's Welfare Plans shall be liable for all claims incurred with respect to Transferring Employees and their eligible dependents after the Closing. For purposes of this Section 8.05, a claim shall be deemed “incurred” on the date that the event, illness, injury or disability that gives rise to the claim occurs (for purposes of life insurance, severance, sickness, accident and disability programs) or on the date that treatment or services are provided (for purposes of health care programs).

8.06    Workers' Compensation Claims. Seller shall be solely responsible for and shall pay any and all workers' compensation and other similar statutory or common law claims asserted by or with respect to Employees (a) outstanding as of the Closing or (b) that arise from or relate to any injury or other compensable event or occupational illness or disease that occurred or is attributable to any event, state of facts or condition that existed or occurred prior to or at the Closing. Purchaser shall be responsible for and shall pay any and all workers' compensation and other similar statutory and common law claims asserted by or with respect to Transferring Employees after the Closing that arise from or relate to any injury or other compensable event or occupational illness or disease that occurred or is attributable to any event, state of facts or condition that existed or occurred after the Closing; provided, however, that liability for claims relating to any events, state of facts or condition occurring both prior to and after the Closing shall be allocated between Purchaser and Seller proportionately with each Party's proportionate share of such liability to be equal to a fraction, the denominator of which shall be the claiming Transferring Employee's total length of such exposure to the claim's underlying cause, and the numerator of which shall be, (i) with respect to Seller, such claiming Transferring Employee's total length of such exposure prior to the Closing, and (i) with respect to Purchaser, such claiming Transferring Employee's total length of such exposure following the Closing.

8.07    Continuing Obligations of Seller. Except as otherwise expressly provided in Section 8.06 or Section 8.12, following the Closing, Seller will continue to be solely responsible for any Losses arising out of, relating to, or resulting from the employment relationship between Seller and the Employees and/or the termination thereof (including, without limitation, Losses related to wages, compensation, benefits, leave, accommodation, vacation, severance pay, termination pay, notice of termination of employment or pay in lieu of such notice whether statutory, contractual or arising under common law, wrongful dismissal or other compensation, payments, benefits, obligations, or liabilities and including any termination of employment with Seller or its Affiliates that occurs as a result of the Closing).

8.08    Obligations of Purchaser. From and after the Closing, Purchaser shall be solely responsible for any Losses (excluding any Losses relating to Retained Liabilities) arising out of, relating to, or resulting from, the employment relationship between Purchaser and the Transferring Employees and/or the termination thereof. For the avoidance of doubt, any Losses accruing after the Closing, but based upon acts, events, or omissions occurring prior to or at the Closing with respect to Seller's employment relationship with the Transferring Employees remain the sole responsibility of Seller pursuant to the terms of Section 8.07 and the exceptions contained therein.

8.09    Compensation and Benefits. Purchaser agrees that during the period commencing at the Closing and ending 18 months after the Closing Date, the Transferring Nonunion Employees will continue to be provided with base salary and incentive compensation opportunities not less than those in effect

immediately prior to the Closing, subject to changes required by applicable Law, as reasonably determined by Purchaser, and (ii) subject to Sections 8.10, 8.12 and 8.15, retirement and welfare benefits, and perquisites that are substantially similar in the aggregate to those provided under the applicable Business Benefit Plans immediately prior to the Closing (the “Purchaser Benefit Plans”). Notwithstanding any provision to the contrary, any change in control severance agreements, severance plan or policy, and any sale, retention, stay or similar bonuses provided by Seller will not be taken into account when determining if Purchaser has met its obligations under the immediately preceding sentence. Purchaser shall cause any Purchaser Benefit Plans in which the Transferring Nonunion Employees are eligible to participate to take into account for purposes of eligibility and vesting, determining the amount of any severance benefits, and for purposes of qualifying for subsidized early retirement benefits (in each case, except to the extent it would result in a duplication of benefits), service by the Transferring Nonunion Employees as if such service were with Purchaser, to the same extent such service was credited under a comparable Business Benefit Plan.

8.10    Medical Benefits and Pre-existing Conditions. Without limiting the application of Section 8.05, Purchaser shall (a) use reasonable best efforts to waive any limitation on medical coverage for Transferring Employees due to pre-existing conditions under the applicable Purchaser Benefit Plans to the extent such limitations were waived for Transferring Employees under the applicable Business Benefit Plans prior to the Closing and (b) to the extent Seller provides such information to Purchaser within 30 days following the Closing Date, credit fully, in the applicable Purchaser Benefit Plans, each Transferring Union Employee and Transferring Nonunion Employee with all deductible payments and other out-of-pocket payments paid by such Transferring Union Employee and Transferring Nonunion Employee under the Business Benefit Plans which provide medical benefits prior to the Closing during the year in which the Closing occurs for the purpose, as applicable, of determining the extent to which any Transferring Union Employee or Transferring Nonunion Employee has satisfied his or her deductible and out-of-pocket maximum under such Business Benefit Plans for such year. Each Party shall timely provide the other Party with such records and information as may be reasonably requested by the other Party in order to enable the Parties to effect the foregoing.

8.11    Severance and COBRA. Purchaser shall adopt one or more severance pay policies effective as of the Closing which, for employment terminations of Transferring Nonunion Employees occurring within 6 months following the Closing Date, provide severance benefits to each Transferring Nonunion Employee on a basis no less favorable than those provided to such Transferring Nonunion Employee under a Business Benefit Plan providing for severance benefits in effect and applicable to him or her immediately prior to the Closing. For the avoidance of doubt, Purchaser shall have no obligation to provide a severance pay plan or policy to Transferring Nonunion Employees whose employment terminates more than 6 months following the Closing Date. Subject only to the obligations of the Provider under the Transition Services Agreement, Purchaser shall have sole responsibility for “continuation coverage” benefits for all Transferring Employees and “qualified beneficiaries” of Transferring Employees for whom a “qualifying event” occurs after the Closing. Seller shall have sole responsibility for “continuation coverage” benefits for all Transferring Employees and “qualified beneficiaries” of Transferring Employees for whom a “qualifying event” occurs prior to or at the Closing (including all qualifying events that occur in connection with the Closing) and for all Employees who do not become Transferring Employees and such Employees' “qualified beneficiaries” for whom a “qualifying event” occurs prior to, at or after the Closing. The terms “continuation coverage,” “qualified beneficiaries,” and “qualifying event” shall have the meanings ascribed to them under Section 4980B of the Code and Sections 601-608 of ERISA.

8.12    Vacation Time. Purchaser shall recognize and honor any earned and unused paid time off and/or vacation time as of the Calculation Time for the benefit of the Transferring Employees, to the extent accrued in the Closing Working Capital.

8.13    Defined Contribution Plans. No later than 30 days following the Closing Date, Purchaser shall cover (or cause to be covered) each Transferring Employee under one or more tax-qualified defined contributions plans and trusts that qualify under Section 401(a) of the Code (collectively, the “Purchaser Contribution Plans”). In addition, Purchaser shall cause one or more Purchaser Contribution Plans to

accept a direct rollover of, or an eligible rollover of, all or a portion of a distribution of the account balance, including any outstanding loan, from the Alcancorp Employees' Savings Plan or the Alcancorp Hourly Employees' Savings Plan of each Transferring Employee who has commenced employment with Purchaser as a rollover contribution; provided, however, that Purchaser Contribution Plans shall only be required to accept rollovers of outstanding loans during the 90 day period following the Closing Date. Seller shall amend the loan procedures under the Alcancorp Employees' Savings Plan or the Alcancorp Hourly Employees' Savings Plan to permit Transferring Employees to continue to make payments of any outstanding loan under such plan during the 90 day period following the Closing Date.

8.14    Pension Plans.

(a)The Assumed Plan. Seller shall transfer or cause its Affiliate to transfer sponsorship of the Assumed Plan to Purchaser or its Affiliates effective as of the Closing. Purchaser or its Affiliates agree to assume sponsorship of the Assumed Plan and assume all assets and liabilities arising under or with respect to the Assumed Plan as of the Closing, including for the avoidance of doubt, all past, present, and future Employees who have rights and benefits thereunder. In connection with the transfer of sponsorship of the Assumed Plan to the Purchaser or its Affiliates:

(i)Seller shall cause the assets of the Assumed Plan that are held in the Rio Tinto America Master Trust (the “Seller Master Trust”) to be transferred in cash to a new trust of which the Purchaser or one of its Affiliates is the settlor (the “Purchaser Trust”);

(ii)Purchaser shall establish the Purchaser Trust as soon as practicable following the Closing;

(iii)Purchaser shall use commercially reasonable efforts to cause the Purchaser Trust to be exempt from tax under Code Section 501(a) and to satisfy the terms of the Union Agreement;

(iv)the Parties shall execute such documents as may be reasonably necessary to cause the transfer of the assets of the Assumed Plan to the Purchaser Trust;

(v)Purchaser shall notify Seller in writing when the Purchaser Trust has been established and when the assets of the Assumed Plan can be transferred to the Purchaser Trust (which notice shall be delivered no later than 60 days after the Closing Date), and Seller shall effect such transfer no later than 7 days after receipt of such notice;

(vi)from the Closing to the date of transfer, Seller shall cause the assets of the Master Trust allocable to the Assumed Plan (the "Allocable Assets") to continue to be invested in accordance with the investment policy and procedures pertaining to the Master Trust, provided that such assets may be converted to cash at the discretion of the Trustee of the Master Trust as may be necessary or desirable to effect such transfer. The Allocable Assets shall reflect gains, losses, expenses, contributions and distributions of the Master Trust of the Assumed Plan incurred from the Closing to the date of transfer; and

(vii)the Assumed Plan and Purchaser shall be responsible for all liabilities and obligations of the Assumed Plan, including benefits accrued prior to the Closing, for which Seller or its relevant Affiliate is liable prior to the Closing and benefits payable to any participants in such plan who retired or separated from service prior to the Closing except to the extent such liabilities arise in connection with Seller's breach of a representation or warranty (whether or not expired) made herein or in any Ancillary Agreement.

Seller shall file all required notices with the Pension Benefit Guaranty Corporation and any other government agency that will be triggered by the Parties entering into this Agreement or by the consummation of the transaction contemplated by this Agreement, in full compliance with applicable Law, including, but not limited to, Section 4043 of ERISA and the regulations thereunder for any reportable event. Seller and Purchaser

shall cooperate to make any and all filings and submissions to the appropriate governmental agencies required to be made by Seller or Purchaser as are appropriate in effectuating the provisions of this Section 8.14. From and after the Closing, Purchaser shall indemnify and hold Seller harmless with respect to any and all liabilities arising under or with respect to the Assumed Plan except to the extent such liabilities arise in connection with Seller's breach of a representation or warranty made under this Agreement.

(b)Alcancorp Pension Plan. For the benefit of the Transferring Nonunion Employees who have accrued benefits under the Alcan Aluminum Corporation Alcancorp Pension Plan (the “Alcancorp Pension Plan”), Seller shall ensure that the Transferring Nonunion Employees cease to participate in and accrue benefits under the Alcancorp Pension Plan. Seller shall cause the Alcancorp Pension Plan to fully vest all of a Transferring Nonunion Employee's benefits under the Alcancorp Pension Plan as of the Closing Date. For the avoidance of doubt, it is agreed and understood that with respect to the Transferring Nonunion Employees and the Alcancorp Pension Plan, (a) Seller shall not cause any assets to be transferred from the Alcancorp Pension Plan to Purchaser or any Purchaser Contribution Plan or any other plan of Purchaser or its Affiliates, (b) neither Purchaser nor any Purchaser Contribution Plan nor any other plan of Purchaser or its Affiliates shall assume any liabilities under the Alcancorp Pension Plan, and (c) all obligations and liabilities under the Alcancorp Pension Plan arising or accruing at any time with respect to the Transferring Nonunion Employees shall remain solely and exclusively with Seller.

8.15    Retiree Medical Coverage. Subject only to the obligations of the Provider under the Transition Services Agreement, Purchaser shall be responsible for providing any post-retirement health and welfare benefits to Transferring Union Employees in accordance with the requirements of the Union Agreement. Seller shall remain responsible and solely liable for providing any post-retirement health and welfare benefits to (a) Employees who do not become Transferring Employees, (b) all former employees of the Facility, and (c) those Nonunion Employees who as of the Closing Date are or, with the passage of time and continued employment with Seller for a period of 5 years after the Closing Date would have become, eligible to receive retiree medical coverage. Notwithstanding the foregoing, this provision shall not constitute an acknowledgment by either Seller or Purchaser that either was obligated to continue to provide any level of such benefits for any period of time.

8.16    WARN Act. Seller shall provide any notices to Employees that may be required under any applicable Law, including the WARN Act or any similar Law, with respect to events that occur prior to or as of the Closing. Purchaser shall provide any notices to Transferring Employees that may be required under any applicable Law, including the WARN Act or any similar Law, with respect to events that occur after the Closing.

8.17    No Third Party Beneficiaries. No provision of this Article 8 shall (a) create any third party beneficiary or other rights in any employee or former employee (including any beneficiary or dependent thereof) of the Seller, of the Purchaser, any of their Affiliates, or any other Person other than the Parties and their respective successors and permitted assigns, (b) constitute or create or be deemed to constitute or create an employment agreement, or (c) constitute or be deemed to constitute an amendment to any employee benefit plan sponsored or maintained by Seller, Purchaser or any of their Affiliates.

8.18    Cooperation. Each of Purchaser and Seller agree to make their respective commercially reasonable efforts and to cooperate fully in complying with the provisions of this Article 8. Without limiting the generality of the foregoing, each of the Parties agrees to execute, deliver and file all documents and to take all such actions as are reasonably necessary or desirable in order to carry out and perform the purpose of this Article 8 and to facilitate the transactions referred to in this Article 8. Without limiting the generality of the foregoing, Seller agrees to use its commercially reasonable efforts to cooperate with Purchaser in endeavoring to obtain the consent of all third party administrators and insurers of the Business Benefit Plans to enter into an agreement with the Purchaser to provide the third party administrators' services and the insurance policies with respect to the Purchaser Benefit Plans after the Closing on the terms and conditions no less favorable than what would have been applicable to Purchaser in 2013.

9.01    Indemnity by Seller. Seller shall, to the fullest extent permitted by Law, indemnify, defend, reimburse, and hold harmless Purchaser and its shareholders, officers, directors, employees and representatives, Affiliates, successors and assigns (each of whom may be an Indemnitee pursuant to this Section 9.01, and all of whom are collectively referred to herein as the “Purchaser Indemnitees”) from and against any and all Losses (including from Third-Party Claims) arising out of, relating to, or resulting from (a) any breach or nonfulfillment by Seller of a covenant or other agreement of Seller set forth in this Agreement or any Ancillary Agreement, (b) the failure to be true and correct as of the date hereof (or the date of execution with respect to any Ancillary Agreement), and as of the Closing (as if made anew at and as of that time), of any representation or warranty of Seller set forth in this Agreement (or the certificate delivered pursuant to Section 6.03(b)) or any Ancillary Agreement, (c) any Excluded Asset or Retained Liability, (d) the EPA NESHAP Claim, including in connection therewith any Losses arising out of, relating to, or resulting from (i) imposed production limitations on the Facility or use limitations on any of the Purchased Assets, (ii) capital expenditures binding on Purchaser following the Closing or that are not paid by Seller, (iii) business interruption or reduction at the Facility, or (iv) imposed limitation on the future ability to increase production output to the Facility's permitted capacity, or (e) any Indemnifiable Labor and Employment Matter.

9.02    Indemnity by Purchaser. Purchaser shall, to the fullest extent permitted by Law, indemnify, defend, reimburse, and hold harmless Seller and its shareholders, officers, directors, employees and representatives, Affiliates, successors and permitted assigns (each of whom may be an Indemnitee pursuant to this Section 9.02, and all of whom are collectively referred to herein as the “Seller Indemnitees”), from and against any and all Losses (including from Third-Party Claims) arising out of, relating to, or resulting from (a) any breach or nonfulfillment by Purchaser of a covenant or other agreement of Purchaser set forth in this Agreement or any Ancillary Agreement, (b) the failure to be true and correct as of the date hereof (or the date of execution with respect to any Ancillary Agreement), and as of the Closing (as if made anew at and as of that time), of any representation or warranty of Purchaser set forth in this Agreement (or the certificate delivered pursuant to Section 6.03(c)) or any Ancillary Agreement, (c) the Assumed Liabilities, (d) the use of the Audited 2012 Financial Statements in any third-party financing obtained by Purchaser or any of its Affiliates, but excluding any Losses that arise out of, relate to or result from the failure to be true and correct as of the date hereof (or the date of execution with respect to any Ancillary Agreement), and as of the Closing (as if made anew at and as of that time), of any representation or warranty (whether or not expired) of Seller set forth in this Agreement (or the certificate delivered pursuant to Section 6.03(b)) or any Ancillary Agreement or that relate to any matter for which Seller has an obligation under Section 9.01 (or would have had such an obligation but for the limitations set forth in Section 9.08), and (e) the Power Contract and the PC Related Agreements to the extent such Losses first arise or accrue at or after, or are otherwise properly attributable to periods commencing at or after, the Closing, including to the extent any Losses arise out of, relate to, or result from the termination of the Power Contract or any PC Related Agreement by Purchaser or any of its Affiliates following the Closing, but excluding any Losses that arise out of, relate to, or result from (i) breaches or defaults under the Power Contract or a PC Related Agreement that (A) occurred at or prior to the Closing, including actions taken with respect to providing the Termination Notice and Termination Certificate, or (B) relate to acts or omissions at or prior to the Closing that, with notice or lapse of time or both, would constitute a breach or default under the Power Contract or any PC Related Agreement, (ii) any breach or nonfulfillment by Seller of a covenant or other agreement of Seller set forth in this Agreement or any Ancillary Agreement or (iii) the failure to be true and correct as of the date hereof (or the date of execution with respect to any Ancillary Agreement), and as of the Closing (as if made anew at and as of that time), of any representation or warranty of Seller set forth in this Agreement (or the certificate delivered pursuant to Section 6.03(b)) or any Ancillary Agreement.

9.03    Notification of Third-Party Claims. Subject to the provisions of Section 7.08 hereof with respect to Tax audits, assessments and proceedings, with respect to any Third-Party Claim against an Indemnitee, the Indemnitee shall deliver to the Indemnitor within the Notice Period a notice setting forth in reasonable detail the facts known to Indemnitee giving rise to such Third-Party Claim and stating that the Indemnitee intends to seek indemnification for such Third-Party Claim from the Indemnitor pursuant to this

Article 9 (“Claim Notice”); provided, that a failure to deliver the Claim Notice within the Notice Period shall not affect the obligations of the Indemnitor with respect to any such Third-Party Claim, unless (and then only to the extent that) the Indemnitor can demonstrate that it has been prejudiced by such failure. Notwithstanding anything to the contrary contained herein, no claim for indemnity by an Indemnitee against an Indemnitor shall be made pursuant to this Article 9 unless notice has been given of such claim to such Indemnitor prior to the applicable survival period, if any, set forth in Section 9.07.

9.04    Defense of Third-Party Claims. Upon receipt of a Claim Notice from an Indemnitee with respect to any Third-Party Claim, the Indemnitor, at its sole expense, may assume the defense thereof with counsel reasonably satisfactory to such Indemnitee and the Indemnitee, at the Indemnitor's expense, shall cooperate in all reasonable respects in such defense; provided, that in order to assume the defense of such Third-Party Claim the Indemnitor must first acknowledge in writing to the Indemnitee its unqualified obligation to indemnify the Indemnitee as provided hereunder; and provided further, that Seller shall not be entitled to assume, at the Indemnitor's expense, the defense of any Third-Party Claim which could reasonably be expected to interrupt or restrict in a material manner Purchaser's ownership, use or operation of the Facility or the Purchased Assets. The Indemnitee shall have the right at its sole expense to employ separate counsel in any action regarding such claim that is being defended by Indemnitor and to participate in the defense thereof; provided, however, that such Indemnitee shall be entitled to participate in any such defense with separate counsel reasonably acceptable to the Indemnitor at the expense of the Indemnitor if (a) so requested by the Indemnitor to participate or (b) in the reasonable opinion of both counsel to the Indemnitee and counsel to the Indemnitor (or, if they disagree, of an independent counsel acceptable to each of them) a conflict or potential conflict exists between the Indemnitee and the Indemnitor that would make such separate representation advisable; provided further that the Indemnitor shall not be required to pay for more than one such counsel (plus any appropriate local counsel) for all Indemnitees in connection with any single Third-Party Claim. If the Indemnitor fails to give the Indemnitee written notice within 30 days after notice from Indemnitee of any Third-Party Claim that Indemnitor is assuming the defense of the Third-Party Claim, or if the Indemnitor fails to assume and continually maintain the defense of the Third-Party Claim, Indemnitee may assume sole control of defense and settlement of such claim, and if that Third-Party Claim is one as to which the Indemnitee was entitled to indemnification hereunder, all Losses incurred by the Indemnitee as a result of the defense and settlement or other resolution of that claim shall be incurred at Indemnitor's expense. If the Third-Party Claim involves only the payment of money, the Indemnitor timely notifies Indemnitee that it will defend such claim, timely and continuously maintains defense of such claim, pays whatever monies are necessary to settle such claim and Indemnitor obtains a release of such claim in favor of the Indemnitee, the Indemnitor may conduct such defense in the name of or on behalf of the Indemnitee or the Indemnitor, and shall have control of the defense and settlement with respect thereto, subject to Indemnitee's right to involve its own counsel at its own expense to protect its interests and the duty of the Parties to cooperate. If the Third-Party Claim involves injunctive or nonmonetary relief, Indemnitor shall not enter into a settlement or consent to any injunction or other nonmonetary relief without the Indemnitee's prior written consent and Indemnitee may fully participate in the defense of such claim at its sole expense (subject to the provisions above relating to the retention of separate counsel at Indemnitor's expense). Notwithstanding any other provision of this Agreement, Purchaser shall have sole responsibility to administer, at Seller's expense, any claims arising out of Seller's indemnification obligations with respect to any Indemnifiable Labor and Employment Matter, and to settle (following first seeking the advice of and consultation with Seller) any claims on terms deemed reasonable by Purchaser in its sole discretion.

9.05    Notice of Other Claims. In the event that any Indemnitee has a claim against any Indemnitor under or in connection with this Agreement that does not involve a Third-Party Claim, the Indemnitee shall notify the Indemnitor of such claim with reasonable promptness following the date on which the Indemnitee becomes aware of any such claim; provided, that a failure to provide any such notice shall not affect the obligations of the Indemnitor with respect to any such claim, unless (and then only to the extent that) the Indemnitor can demonstrate that it has been prejudiced by such failure. The notice shall specify the nature of and specific basis for such claim and the amount of such claim, if known, and shall be accompanied by an invoice in the amount of the claim, if known. Subject to the following sentence, the Indemnitor shall remit

payment for the amount of such claim promptly following receipt from the Indemnitee of the notice and invoice therefor. In the event of a dispute regarding any such claim, the Indemnitee and the Indemnitor shall proceed in good faith to negotiate a resolution of such dispute, and if not resolved through negotiations, such dispute will be resolved by Litigation in an appropriate court of competent jurisdiction. Notwithstanding anything herein to the contrary, no claim for indemnity by an Indemnitee against an Indemnitor shall be made pursuant to this Article 9 unless notice has been given of such claim to such Indemnitor prior to the expiration of the applicable survival period, if any, set forth in Section 9.07.

9.06    Legal Fees; Access and Cooperation. The Indemnitor shall reimburse the Indemnitee for all reasonable legal fees and other out-of-pocket expenses reasonably incurred by the Indemnitee in successfully pursuing any claim for indemnification against the Indemnitor hereunder. The Indemnitor shall also be responsible for the payment of all reasonable legal fees and other out-of-pocket expenses reasonably incurred by the Indemnitee or the Indemnitor in defending any Third-Party Claims, except those legal fees incurred by an Indemnitee who elects to employ separate counsel to participate in the defense of a Third-Party Claim (subject to the provisions in Section 9.04 relating to the retention of separate counsel at Indemnitor's expense). After the Closing, each Indemnitee shall cooperate with each Indemnitor, and each Indemnitor shall cooperate with each Indemnitee, as to all claims for indemnification hereunder, and each Indemnitee shall make available to each Indemnitor, each Indemnitor shall make available to each Indemnitee, as reasonably requested all information, records and documents relating to all claims and shall preserve all such information, records and documents until the termination of any claim or the period during which any claim may be made; provided, however, that no Indemnitee or Indemnitor shall be required to provide access to or to disclose information to the extent such access or disclosure would jeopardize the attorney-client privilege of such Indemnitee or Indemnitor or violate any applicable Law or breach any applicable agreement, in which case such Indemnitee or Indemnitor shall provide access to or disclose such information to the fullest extent permitted by such Law or agreement or consistent with such privilege. Further, each Indemnitee shall also make available to each Indemnitor, as reasonably requested, its personnel (including technical and scientific), agents and other representatives who are responsible for preparing or maintaining information, records or other documents, or who may have particular knowledge with respect to any claim.

9.07    Survival of Representations, Warranties and Covenants. The representations and warranties of each of Seller and Purchaser set forth in this Agreement and in any certificate or instrument delivered in connection herewith shall survive the Closing as follows: (a) the representations and warranties in Sections 4.01 and 5.01 (Organization), Sections 4.02 and 5.02 (Authority), Sections 4.13 and 5.06 (Brokers), and Section 4.14(a) (Title to Assets; Sufficiency), shall survive indefinitely; (b) the representations and warranties in Section 4.09 (Environmental Matters) shall survive until the 10th anniversary of the Closing Date; (c) the representations and warranties in Section 4.10 (Benefit Plans) and Section 4.15 (Safety and Health) shall survive until 90 calendar days after the expiration of the statute of limitations applicable to the matters covered thereby; and (d) all other representations and warranties shall survive until the 2nd anniversary of the Closing Date. The covenants contained in this Agreement shall, subject to any express durations contained therein, survive indefinitely. Seller shall not be required to indemnify any Purchaser Indemnitee with respect to Retained Liabilities described in Section 2.05(g) (other than the EPA NESHAP Claim) unless notice of any such claim for indemnification is provided on or prior to the 20th anniversary of the Closing Date.

9.08    Limitations on Indemnification.

(a)Seller shall not be required to indemnify Purchaser Indemnitees with respect to any claim for indemnification pursuant to Section 9.01(b) (other than with respect to Section 4.09) unless and until the aggregate amount of its Losses exceeds $1 million (the “Threshold Amount”), in which case Seller shall only be responsible for the aggregate amount of such Losses in excess of the Threshold Amount. In no event shall the aggregate liability of Seller to Purchaser Indemnitees with respect to any claim for indemnification pursuant to Section 9.01(b) (other than with respect to Section 4.09 and the certificate to be delivered by Seller to Purchaser in accordance with Section 6.03(b) to the extent it relates to Section

4.09) exceed $8,125,000 (the “Cap”). In no event shall the aggregate liability of Seller to Purchaser Indemnitees with respect to any claim for indemnification pursuant to (i) Section 9.01(b) relating to the representations and warranties set forth in Section 4.09 and the certificate to be delivered by Seller to Purchaser in accordance with Section 6.03(b) to the extent it relates to Section 4.09 or (ii) Section 9.01(c) to the extent it relates to the Retained Liabilities described in Section 2.05(g) (other than the EPA NESHAP Claim), exceed $20 million (the “Environmental Cap”). The Environmental Cap shall be reduced by $2 million on each anniversary following the 10th anniversary of the Closing Date, provided, however, that with respect to any claim for indemnification made against Seller by a Purchaser Indemnitee in which the Environmental Cap applies pursuant to the terms of this Agreement, the amount of the Environmental Cap applicable to such claim shall be the amount of the Environmental Cap as in effect as of the date Seller was first notified of such claim in accordance with the terms of this Agreement.

(b)Subject to the last sentence of this clause (b), Purchaser shall not be required to indemnify Seller Indemnitees with respect to any claim for indemnification pursuant to Section 9.02(b) unless and until the aggregate amount of its Losses exceeds the Threshold Amount, in which case Purchaser shall only be responsible for the aggregate amount of such Losses in excess of the Threshold Amount. Subject to the last sentence of this clause (b), in no event shall the aggregate liability of Purchaser to Seller Indemnitees with respect to any claim for indemnification pursuant to Section 9.02(b) exceed the Cap. With respect to the indemnification pursuant to Section 9.02(d) and Section 9.02(e), the Purchaser's liability thereunder shall not be subject to or limited by either the Threshold Amount or the Cap.

(c)Notwithstanding the foregoing, the limitations set forth in this Section 9.08 with respect to the Threshold Amount and the Cap shall not apply to Losses arising out of, relating to, or resulting from any failure of any representation or warranty contained in Sections 4.01 and 5.01 (Organization), Sections 4.02 and 5.02 (Authority), Section 4.08(c) (Power Contract Termination), Section 4.10 (Benefit Plans), Sections 4.13 and 5.06 (Brokers) or Section 4.14(a) (Title to Assets; Sufficiency) of this Agreement (or any corresponding representation or warranty made in the certificates delivered pursuant to Sections 6.03(b) and 6.03(c)) to be true and correct.

(d)Except for the $1 million cash payment to be made to Purchaser pursuant to the terms of Section 7.20, Purchaser shall not be entitled to indemnification under this Article 9 for Losses to the extent arising from Seller's failure to deliver the Audited 2012 Financial Statements to Purchaser on or prior to May 15, 2013.

(e)Purchaser shall not be entitled to indemnification under this Article 9 for those portions of any Losses to the extent they were included in any adjustment to the Base Purchase Price pursuant to Section 3.01(b) as a result of being included in the Closing Working Capital or the Apportionments. For the avoidance of doubt, no Indemnitee shall be compensated more than once for the same Loss.

(f)The rights to indemnification provided for in this Article 9 shall be THE SOLE AND EXCLUSIVE REMEDY OF PURCHASER INDEMNITEES AND SELLER INDEMNITEES, as the case may be, after the Closing for any breaches of or inaccuracy of any representation, warranty, covenant or agreement of Seller or Purchaser, respectively, herein or any other breach of or claim under this Agreement, AND EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ALL OTHER RIGHTS AND REMEDIES THAT MAY ARISE UNDER, OR EXIST BY VIRTUE OF, APPLICABLE LAW, other than, in each case, with respect to claims of, or causes of action arising from, fraud or intentional misrepresentation and contribution and other claims arising under CERCLA. This Article 9 shall not affect the rights of Purchaser or Seller to obtain specific performance of any provision of this Agreement or appropriate injunctive relief.

9.09    Materiality Qualifications. For purposes of calculating Losses hereunder, any materiality or Material Adverse Effect qualifications in the representations, warranties, covenants and agreements shall be disregarded.

9.10    Knowledge. Except for matters disclosed in the Disclosure Schedules, to the extent that such matters constitute express exceptions to Seller's representations and warranties, the right to indemnification or any other remedy based on representations, warranties, covenants and agreements in this Agreement or the certificates delivered pursuant to Sections 6.03(b) and 6.03(c), or any Ancillary Agreement, shall not be affected by any investigation conducted, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to the accuracy or inaccuracy of any such representation or warranty or Seller's or Purchaser's compliance with any such covenant or agreement.

10.1    Entire Agreement; Amendments. This Agreement, the Ancillary Agreements, and the Disclosure Schedules and exhibits attached hereto and thereto constitute the entire agreement of the Parties with respect to the subject matter hereof and supersede all prior agreements, arrangements and communications of the Parties dealing with such subject matter, whether oral or written. No other promise, agreement, understanding, or representation will be binding unless made in writing and signed by the Parties. All amendments to this Agreement must be in writing and signed by all of the Parties.

10.2    Expenses. Except as otherwise expressly provided in this Agreement, each Party shall pay all costs and expenses incurred by it in respect of the transactions contemplated by this Agreement (including those contemplated by the Ancillary Agreements) and all investigations and proceedings in connection therewith, including expenses of such Party's counsel, accountants and investment advisors.

10.03    Further Assurances. At any time, and from time to time, after the Closing, each Party shall execute such additional instruments and take such action as may be reasonably requested by one or more of the other Parties to confirm or perfect title to any property transferred hereunder or otherwise to carry out the intent and purposes of this Agreement and the Ancillary Agreements.

10.4    Waiver. The failure (with or without intent) of any Party to insist upon the strict performance by any other Party of any provision of this Agreement shall not be deemed to constitute a modification of any of the provisions hereof, or a waiver of the right to insist at any time thereafter upon performance strictly in accordance with the provisions of this Agreement. Any Party may waive any term, condition or provision of this Agreement, but no such waiver shall be effective unless made in a writing signed by the Party against whom the waiver is sought to be enforced. No waiver of any term, condition or provision shall operate as a waiver of any other term, condition or provision of the Agreement, and no waiver of any term, condition or provision shall operate as a continuing waiver except to the extent specifically stated in such waiver.

10.5    Certain Waivers. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EXCEPT (A) WITH RESPECT TO THIRD-PARTY CLAIMS AS TO WHICH SUCH DAMAGES WERE ASSESSED, AND (B) AS PROVIDED IN THE NEXT SUCCEEDING SENTENCE, THE PARTIES TO THIS AGREEMENT EXPRESSLY WAIVE AND FOREGO ANY RIGHT TO RECOVER PUNITIVE OR EXEMPLARY DAMAGES, LOST PROFITS, CONSEQUENTIAL OR SIMILAR DAMAGES, IN EACH CASE IN ANY LITIGATION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ANCILLARY AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. NOTWITHSTANDING THE IMMEDIATELY PRECEDING SENTENCE AND SUBJECT TO THE APPLICATION, IF APPLICABLE, OF THE THRESHOLD AND THE CAP, PURCHASER SHALL BE ENTITLED TO RECOVER LOST PROFITS, CONSEQUENTIAL OR SIMILAR DAMAGES FROM SELLER, BUT ONLY TO THE EXTENT THAT THEY RESULT FROM OR ARE CAUSED BY ANY INTENTIONAL OR KNOWING ACT OR OMISSION OF SELLER OR ANY OF ITS AFFILIATES. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (a) NO REPRESENTATIVE,

AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (b) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (c) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (d) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.05.

10.6    Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been given if (a) delivered in person (to the individual whose attention is specified below) or via facsimile or electronic mail (followed immediately with a copy in the manner specified in clause (b) or (c) hereof), (b) sent by prepaid first-class registered or certified mail, return receipt requested, or (c) sent by FedEx or similar next-day or overnight mail or delivery, as follows:

10.07    Governing Law. This Agreement and the rights and obligations of the Parties shall be governed by and construed in accordance with the internal laws of the State of New York, without presumption or construction against the Party preparing it and without giving effect to the conflicts of law principles thereof, in every respect, including validity, interpretation and performance, notwithstanding that one or more of the Parties to this Agreement may now be or hereafter become domiciled in another state or a foreign country.

10.08    Jurisdiction. The Parties agree that any federal or state court located in New York, New York, shall have jurisdiction over the Parties, and each of the Parties hereby consent to the jurisdiction of such courts. The Parties further acknowledge and agree that this provision does not constitute an exclusive forum selection clause.

10.09    Concerning Warranties. It is the explicit intent and understanding of each of the Parties that no Party nor any of its Affiliates or representatives is making any representation or warranty whatsoever, oral or written, express or implied, other than those set forth in Article 4 and Article 5 (or any corresponding representation or warranty made in the certificates delivered pursuant to Sections 6.03(b) and 6.03(c)), and no Party is relying on any statement, representation or warranty, oral or written, express or implied, made by the other Party or such other Party's Affiliates or representatives (including with respect to any estimates, projections, forecasts, budgets or other forward-looking information delivered or made available to Purchaser or its representatives) except for the representations and warranties set forth in such Articles or in the certificates delivered pursuant to Sections 6.03(b) and 6.03(c). EXCEPT AS OTHERWISE SPECIFICALLY SET FORTH IN THIS AGREEMENT (or in the certificates delivered pursuant to Sections 6.03(b) and 6.03(c)), SELLER EXPRESSLY DISCLAIMS ANY IMPLIED WARRANTY OR REPRESENTATION AS TO CONDITION, MERCHANTABILITY OR SUITABILITY AS TO ANY OF THE PURCHASED ASSETS AND, EXCEPT AS OTHERWISE SPECIFICALLY SET FORTH IN THIS AGREEMENT AND THE CERTIFICATES DELIVERED PURSUANT TO SECTIONS 6.03(B) AND 6.03(C), IT IS UNDERSTOOD AND AGREED THAT PURCHASER TAKES THE PURCHASED ASSETS OF “AS IS” AND “WHERE IS”. The Parties agree that this is an arm's-length transaction in which the Parties' undertakings and obligations are limited to the performance of their obligations under this Agreement. Purchaser acknowledges that it is a sophisticated investor, that it has undertaken a full investigation of the Facility and that it has only a contractual relationship with Seller, based solely on the terms of this Agreement, and that there is no special relationship of trust or reliance between Purchaser and Seller.

10.10    Disclosure Schedules. The disclosure of any matter in the Disclosure Schedules referenced by a particular Section shall be deemed to include and incorporate all disclosures made on any other Disclosure Schedules as and to the extent that the relevance of such matter to such other Disclosure Schedule is reasonably apparent. The disclosure of any matter in the Disclosure Schedules shall expressly not be deemed to constitute an admission by Seller or Purchaser, or to otherwise imply, that any such matter is material for the purposes of this Agreement. The disclosure of any matter in the Disclosure Schedules is not to be treated as constituting or implying any representation, warranty, assurance or undertaking by Seller not expressly set forth in the Agreement, nor to be treated as adding to or extending the scope of any of

Seller's representations or warranties in the Agreement. Unless this Agreement specifically provides otherwise, neither the specification of any dollar amount in any representation or warranty contained in this Agreement nor the inclusion of any specific item or matter in any Schedule is intended to imply that such amount, or higher or lower amounts, or the item or matter so included or other items or matters, are or are not material, and no Party shall use the fact that such amount, item or matter has been set forth in any Schedule in any dispute or controversy between the Parties as to whether any amount, item or matter not described herein or included in any Schedule is or is not material or is or is not in the Ordinary Course of Business, in each case for purposes of this Agreement.

10.11    Illegality or Invalidity. In the event that any provision of this Agreement is held illegal or invalid for any reason, such illegality or invalidity shall at the option of the Party against whom the same is asserted not affect the remaining parts of this Agreement, but this Agreement shall be construed and enforced as if that illegal and invalid provision had never been inserted herein.

10.12    No Third Party Beneficiaries. Except as provided in Article 9 hereof (relating to Indemnitees), nothing in this Agreement shall entitle any Person other than Seller and Purchaser and their respective permitted successors and assigns, to use or rely upon any representation, warranty, or covenant in this Agreement or the Ancillary Agreements or to assert or base any claim, Litigation, remedy or right of any kind under or on this Agreement or the Ancillary Agreements or any representation, warranty, or covenant contained herein or therein.

10.13    Counterparts; Facsimiles and Electronic Signatures. This Agreement may be executed in one or more counterparts, each of which shall be considered an original, and all of which taken together shall constitute one and the same instrument. A facsimile or electronic copy of a signature hereto or to any of the Ancillary Agreements shall be fully effective as of the Closing as if it constituted an original signature hereto. Without limiting the effectiveness of the facsimile or electronic signatures, the Parties agree to deliver or cause to be delivered to each other the original signatures hereto as soon as reasonably practicable following the Closing.

10.14    Successors and Assigns. Seller shall not assign this Agreement or its rights hereunder without the express prior written consent of Purchaser. This Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective permitted transferees, successors and assigns.

Each of the Parties acknowledges that the breach of this Agreement by the other to sell, and cause to be sold, or to purchase or cause to be purchased, the Purchased Assets, shall be enforceable against the breaching Party by a decree of specific performance and appropriate injunctive relief may be applied for and granted in connection therewith, without the requirement to post any bond or security in connection therewith.
