(b) Seller shall cause each Acquired Entity to permit Buyer and its representatives to have reasonable access to each Acquired Entity’s premises to conduct a physical audit of inventory.

5.4. Seller Restrictions.

5.5. Seller Post-Closing Confidentiality Obligation. Seller acknowledges that (a) during the course of its affiliation with each Acquired Entity, it has produced and had access to

confidential information relating to each Acquired Entity (“Confidential Information”), and (b) the unauthorized use or disclosure of any Confidential Information at any time would constitute unfair competition with Buyer and would deprive Buyer of the benefits of this Agreement and the transactions contemplated by this Agreement. Seller agrees that it will hold in confidence the Confidential Information and will not, directly or indirectly, disclose, publish, or otherwise make available any of the Confidential Information to the public or to any Person other than its officers, directors or Affiliates; provided, however, that each Seller may disclose Confidential Information if, but only to the extent, required to do so by Law, provided, however, that in such case, Seller shall provide Buyer with prior written notice thereof so that Buyer may seek an appropriate protective order or other appropriate remedy, and Seller shall cooperate with Buyer in connection therewith and provided, further, that, in the event that a protective order or other remedy is not obtained, Seller shall furnish only that portion of such information which, in the opinion of its counsel, Seller is legally compelled to disclose and shall exercise commercially reasonable efforts to obtain reliable assurance that confidential treatment will be accorded any such information so disclosed.

5.6. Seller Non-Compete. Seller agrees that from the Closing until the third anniversary of the Closing, neither it nor any of its Subsidiaries will engage in any Competing Business in the United States of America and/or China. Notwithstanding the foregoing, this Section 5.6 shall not restrict (a) any acquirer of Seller, its Affiliates, its business or any portion thereof or any Affiliate of such acquirer (other than Seller or any Subsidiary of Seller who is a Subsidiary of Seller prior to such acquisition) from engaging in a Competing Business that was conducted by such acquirer or its Affiliates (other than Seller or any Subsidiary of Seller who is a Subsidiary of Seller prior to such acquisition) prior to such acquisition, and (b) acquiring any Person who is engaged in a Competing Business (either directly or through a Subsidiary), provided that the consolidated revenue of such Person and its Subsidiaries for the 12-month period prior to the date of such acquisition derived from Competing Businesses does not exceed 25 percent of the aggregate consolidated revenue of such Person and its Subsidiaries for such 12-month period. In no event shall ownership of five percent or less of the outstanding securities of any class of any issuer whose securities are registered under the Securities Exchange Act of 1934, as amended, standing alone, be deemed to be engaged in a Competing Business, so long as Seller or any Subsidiary of Seller does not have, or exercise, any rights to manage or operate the business of such issuer other than rights as a stockholder thereof. For purposes of this Agreement, “Competing Business” means a business in which 25 percent or more of the gross revenues for the immediately prior fiscal year is derived from (A) recycling zinc metal and (B) producing zinc oxide and zinc dust. From the Closing until the third anniversary of the Closing, Seller will not, and will cause its Subsidiaries not to, directly or indirectly, induce or solicit, or aid or assist any Person to induce or solicit, any employees, salespersons, agents, consultants, distributors, customers or suppliers of any of the Acquired Entities to terminate, curtail or otherwise limit their employment by or business relationship with any of the Acquired Entities. For the avoidance of doubt, nothing in the immediately preceding sentence shall restrict Seller and its Subsidiaries from making sales to its customers and purchases from its suppliers in the ordinary course of business. The parties hereto agree that the provisions of this Section 5.6 are fair, reasonable and reasonably required for the protection of the Acquired Entities. If a court determines, however, that any provision of this Section 5.6 is unreasonable, either in period of time, geographical area or otherwise, then the parties hereto agree that the provisions of this Section 5.6 should be interpreted and enforced to the maximum extent which such court deems reasonable.

5.7. Employee Matters.

(a) Until the first anniversary of the Closing Date, Buyer shall provide (or cause to be provided) to employees (except any Employees covered by a collective bargaining agreement) of the Acquired Entities who are employees of the Acquired Entities immediately prior to the Closing (the “Company Employees”) (x) base compensation and target bonuses (excluding equity compensation) substantially comparable in the aggregate to those levels in effect immediately prior to the Closing and (y) pension and welfare benefits (excluding equity compensation and any defined benefit pension plan) that are substantially comparable, in the aggregate, to those provided to Company Employees immediately prior to the Closing and which pension and welfare benefits have been set forth in the documents listed on Schedule 3.8(a). With respect to Employees covered by a collective bargaining agreement, such collective bargaining agreement shall govern. Notwithstanding the above, nothing herein shall prevent Buyer’s right or obligation to make such changes to a Company Benefit Plan as necessary to conform with Law. The provisions of this Section 5.7(a) shall not preclude Buyer at any time following the Closing from terminating the employment of any Company Employee for any reason (or no reason).

(b) Subject to its obligations under applicable Law, Buyer, as well as its Subsidiaries, shall give credit for purposes of eligibility and vesting to Company Employees under each of their respective plans, programs and arrangements providing pension and welfare benefits (as applicable) in which Company Employees participate, (to the extent Company Employees receive pension and welfare benefits pursuant to plans of Buyer) for all service prior to the Closing with the Acquired Entities, or any predecessor employer to the extent the Acquired Entity recognized such service, for all purposes for which such service (and to the same extent such service) is credited for similarly situated employees of Buyer, but not to the extent crediting such service would result in duplication of benefits, the crediting of service for benefit accruals under a defined benefit pension plan, or service credit under a newly established plan for which prior service is not taken into account for employees of Buyer or its Affiliates generally.

(c) Subject to its obligations under applicable Law, with respect to Company Employees participation in any Benefit Plan of Buyer, (i) Buyer shall waive or cause to be waived all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Company Employees and their eligible dependents and (ii) in the case of any plans providing health benefits with respect to the calendar year in which the acquisition contemplated by this Agreement takes place, for purposes of satisfying any deductible or out-of-pocket requirements, provide each Company Employee and their eligible dependents with credit for any co-insurance and deductibles paid prior to the Closing under the analogous Company Benefit Plan.

(d) On or prior to the Closing Date, Seller shall take all necessary action to cause the account balances and/or accrued benefits of the Company Employees under the Aleris International, Inc. 401(k) Plan to be fully vested and non-forfeitable as of the Closing Date. As of the Closing Date, Seller shall contribute to the Aleris International, Inc. 401(k) Plan the

matching contributions relating to periods prior to the Closing Date based on the amount or percentage that Seller is required to contribute to such plan on behalf of the Company Employees through the Closing Date as if the Company Employees had satisfied all prerequisites for receiving such contributions as of the Closing Date.

With respect to the Aleris International, Inc. 401(k) Plan, from and after the Closing, Buyer shall reimburse Seller for any matching contribution, retirement age-based contribution, if any, or profit sharing contribution, if any, to the extent made by Seller on or after the Closing and to the extent any such amount is reflected as a liability in the Net Working Capital on the Final Statement of Purchase Price and to the extent that it relates to services performed by Company Employees attributable to the period from January 1, 2007 to the Closing.

If (i) a party other than the parties hereto makes a claim or takes other action to enforce any provision in this Agreement as an amendment to any Benefit Plan of Buyer, and (ii) such provision is deemed to be an amendment to such Benefit Plan of Buyer even though not explicitly designated as such in this Agreement, then, solely with respect to such Benefit Plan of Buyer, such provision shall lapse retroactively and shall have no amendatory effect with respect thereto.

(f) The Parties hereto acknowledge and agree that all provisions contained in this Section 5.7 are included for the sole benefit of the Parties hereto, and that nothing in this Agreement, whether express or implied, shall create any third party beneficiary or other rights (i) in any other Person, including any employees or former employees of the Acquired Entities, any participant in any Company Benefit Plan or Benefit Plan of Buyer, or any dependent or beneficiary thereof, or (ii) to continued employment with Buyer or any of its Affiliates.

Schedule 5.8 contains a true, complete and correct list of the names and the sites of employment or facilities of those individuals who suffered an “employment loss” (as defined in the WARN Act) at any site of employment or facility of the Acquired Entities during the 90-day period prior to the date of this Agreement. Schedule 5.8 shall be updated immediately prior to the Closing Date with respect to the 90-day

period prior to the Closing Date. Prior to the Closing Date, Seller agrees to provide any notice required under the WARN Act to any employee of the Acquired Entities as may be reasonably requested by Buyer in writing.

5.11. Brokers’ Fees. Seller (i) will be solely responsible for any obligations to any Person listed in Schedule 3.17, and (ii) will pay or reimburse Buyer for any Losses resulting from or arising out of any such obligations or the matters described in Schedule 3.17.

ARTICLE VI

Taxes

6.1. Indemnification.

(a) Seller shall be responsible for and shall indemnify and hold harmless the Buyer Indemnitees from and against (i) any and all liabilities of the Acquired Entities for Taxes in respect of Pre-Closing Tax Periods, (ii) any and all liabilities of the Acquired Entities pursuant to Treasury Regulation § 1.1502-6 (or any analogous or similar state, local, or foreign Law) for Taxes of any affiliated, consolidated, combined or unitary group of which any of the Acquired Entities (or any of their predecessors) is or has been a member in respect of any taxable period that ends on or before the Closing Date or any taxable period that ends after the Closing Date but only if such taxable period includes the Closing Date, and any and all liabilities for Taxes of any Person otherwise imposed on any Acquired Entity for any Pre-Closing Tax Period, (iii) any and all liabilities for Taxes arising out of, resulting from or otherwise related to the failure of Seller to comply with its covenants, agreements or obligations under this Article VI or Section 5.1(x) (the “Tax Covenants”), (iv) any and all liabilities of the Acquired Entities for Taxes arising from the making of Section 338 Elections with respect to the Acquired Entities, (v) any and all liabilities for Taxes imposed on any Acquired Entity for any Post-Closing Tax Period as a result of any Tax Sharing Agreement entered into by such Acquired Entity (or its predecessor) prior to the Closing, (vi) reasonable accounting, legal and other out of pocket expenses incurred after the Closing arising out of, resulting from or otherwise related to, any breach or inaccuracy of any Tax Representation (as defined below), any breach of any Tax Covenant or the conduct of any Tax Proceeding (except as otherwise provided in Section 6.4), and (vii) any and all liabilities for Taxes arising out of, resulting from or otherwise related to any breach or inaccuracy in any of the representations or warranties contained in Sections 3.13(f), (i), (o), or (p) (the “Tax Representations”) (it being understood that such representations and warranties shall be interpreted without giving effect to any limitations or qualifications as to “materiality” (including the word “material”) as set forth therein), but only to the extent that with respect to each of clauses (i), (ii), (iii) and (v) such Tax liabilities exceed the aggregate amount of such Taxes (excluding deferred Taxes) that was taken into account in determining Net Working Capital, reduced by any prior offsets to Seller’s liability under this Section 6.1(a) or Section 6.2(e), and without duplication for any amounts paid by Seller pursuant to Section 6.2.

(b) Seller shall pay to the Buyer or the Acquired Entities any amount required to be paid by it pursuant to Section 6.1(a) within the latter of (x) five days after Seller receives written notice from Buyer requesting such payment and (y) two days prior to the date that the indemnified Tax or related expense is required to be paid. The amount of indemnification for Taxes or related expenses pursuant to Section 6.1(a) shall be computed without regard to the set-off or other utilization of any loss, deduction or Tax credit of any Buyer Indemnitee realized in, or attributable to, a Post-Closing Tax Period and, in the case of any Buyer Indemnitee other than the Acquired Entities, any net operating losses, capital losses or Tax credits of such Buyer Indemnitee from a Pre-Closing Tax Period. Notwithstanding any other provision of this Agreement, Section 6.1(a) shall not be interpreted to allow a Buyer Indemnitee to be indemnified more than once for the same amount.

(c) If an Acquired Entity has not made a Section 338 Election, the amount of indemnification for Taxes or related expenses pursuant to Section 6.1(a) or any Loss pursuant to Section 9.3 relating to such Acquired Entity shall be computed by taking into account the tax savings to such Acquired Entity resulting from the incurrence of the item for which indemnification is made, after first taking into account all other tax benefits available to such Acquired Entity. Any payments made by Seller or Buyer under this Article VI or Section 9.3 shall be considered by the parties as an adjustment to the Purchase Price and the parties shall not take any position on any Tax Return or otherwise that is inconsistent with that position. Notwithstanding the foregoing, if upon the resolution or settlement of any Tax Proceeding any payment by Seller to Buyer shall be determined to be taxable income, Seller shall increase the amount of the payment to Buyer so that on an after-Tax basis Buyer is left with an amount equal to the amount of the payment due from Seller before taking the imposition of Taxes on the payment or any additional payment into account. In connection with any such Tax Proceeding, provisions similar to those of Section 6.4(c) and (e) shall apply with respect to the conduct, resolution and settlement of such Tax Proceeding with respect to the relevant Post-Closing Tax Period.

6.2. Filing and Payment Responsibility.

(a) Seller and Buyer shall cause each Acquired Entity, to the extent permitted by Law, (x) to join for all Pre-Closing Tax Periods for which Income Tax Returns have not yet been filed, in the Income Tax Returns of the Federal Tax Group and any Income Tax Returns of State, Local or Foreign Tax Groups which such Acquired Entity joined for its most recent Income Tax Return filed before the date hereof or is required to join and which Tax Returns include Seller or its Affiliates (other than Affiliates which are themselves Acquired Entities) in addition to such Acquired Entity and (y) close its taxable year as of the end of the Closing Date. Seller shall timely prepare and file, or cause to be timely prepared and filed, all such Income Tax Returns in a manner consistent with the prior practices applicable to the preparation of such Tax Returns with respect to the Acquired Entities (including all elections, accounting methods and conventions), except as otherwise required by Law, and in accordance with this Agreement. Seller shall be responsible for and shall timely pay, or cause to be timely paid, all Income Taxes due with respect to such Tax Returns. Seller shall provide, or cause to be provided, to Buyer at least thirty (30) days before each such Income Tax Return is required to be filed (including extensions) a copy of the relevant portions of such Tax Return that relate to the Acquired Entities; provided that in the event that an Acquired Entity makes a Section 338 Election, Seller

shall only be required to provide a copy of the portion of such Income Tax Return if such copy is required to be included as an exhibit or attachment to any Tax Return required to be filed pursuant to Section 6.2(b).

(b) Seller shall timely prepare, or cause to be timely prepared, all Separate Tax Returns of the Acquired Entities for Pre-Closing Tax Periods (other than a Pre-Closing Tax Period included in a Straddle Period). Such Separate Tax Returns shall be prepared in a manner consistent with the prior practices applicable to the preparation of such Tax Returns (including all elections, accounting methods and conventions), except as otherwise required by Law, and in accordance with this Agreement. Seller shall provide each such Income Tax Return to Buyer for its review, comment, and consent to filing, which shall not be unreasonably withheld, no less than thirty (30) days prior to the due date for filing such Tax Return (including extensions). Seller shall make such revisions to such Income Tax Returns as are reasonably requested by Buyer, but only to the extent that such revisions are necessary to cause such Tax Return to be prepared in compliance with Law, in accordance with this Agreement, in a manner consistent with the prior practices applicable to the preparation of such Tax Return, or, if there are no such prior practices, in a manner that does not have the effect of distorting the reporting of income or the claiming of expenses or losses in the applicable Pre-Closing Tax Period.

(c) Buyer shall timely prepare and file, or cause to be timely prepared and filed, (x) all Income Tax Returns of the Acquired Entities for all Straddle Periods and (y) all non-Income Tax Returns of the Acquired Entities for Pre-Closing Tax Periods that are required to be filed after the Closing Date. Buyer shall provide, or cause to be provided, to Seller a copy of each such Tax Return at least thirty (30) days prior to the due date for filing such Tax Return (including extensions) for Seller’s review and comment. Buyer shall make such revisions to such Tax Returns as are reasonably requested by Seller to the extent that such revisions relate to Taxes of any Pre-Closing Tax Period, except (i) where a contrary position is required by Law, (ii) to the extent such comments, if incorporated in any such Tax Return, would cause such Tax Return to be prepared in a manner inconsistent with past Tax Returns, or (iii) to the extent such comments, if incorporated in any such Tax Return, could reasonably be likely to have a material adverse effect (relative to the benefit to Seller resulting from incorporating such comments in such Tax Return) on the liability for Taxes of Buyer or any of the Acquired Entities or its other Affiliates in any Post-Closing Tax Period.

(d) Buyer and Seller shall provide each other with a copy of any Income Tax Return of the Acquired Entities that it files or causes to be filed pursuant to Section 6.2(b) or (c) after the Closing (not including any consolidated or combined Income Tax Returns filed pursuant to Section 6.2(a) which includes Seller or any Affiliate of Seller (other than an Acquired Entity)) no later than ten (10) days after the filing of each such Income Tax Return.

(e) Seller shall, not less than five (5) calendar days prior to the due date (without regard to extensions) of any Tax Return referred to in Section 6.2(b) or Section 6.2(c), provide Buyer with the funds to timely pay the Tax liability due and attributable to the Pre-Closing Tax Period with respect to each such Tax Return, but only to the extent such Tax liability exceeds the aggregate amount of Taxes (excluding deferred Taxes) that was taken into account in determining Net Working Capital, reduced by any prior offsets to Seller’s liability under Section 6.1(a) or this Section 6.2(e). In the case of a Tax Return filed pursuant to an extension,

appropriate adjustments shall be made between Seller and Buyer if, at the time the Tax Return is actually filed, the Taxes due and attributable to the Pre-Closing Tax Period with respect to such Tax Return are more or less than the amount, if any, previously paid by Seller.

(f) Allocation of Tax Liability. In the event applicable Law does not require or permit the parties to close state, local or foreign Tax periods as of the Closing Date, the allocation of Tax liability between the Pre-Closing Tax Period and the Post-Closing Tax Period comprising a Straddle Period shall be made in accordance with this Section 6.2(f) as follows:

(i) in the case of Taxes based upon income, gross receipts (such as sales Taxes) or specific transactions involving Taxes other than Taxes based upon income or gross receipts, the amount of Taxes attributable to any Pre-Closing Tax Period or Post-Closing Tax Period included in the Straddle Period shall be determined by closing the books of the applicable Acquired Entity as of the close of the Closing Date and by treating each of such Pre-Closing Tax Period and Post-Closing Tax Period as a separate taxable year; and

(ii) in the case of Taxes that are determined on a basis other than income, gross receipts or specific transactions, the amount of Taxes attributable to any Pre-Closing Tax Period included in the Straddle Period shall be equal to the amount of such Taxes for the Straddle Period multiplied by a fraction, the numerator of which is the number of days in the Pre-Closing Tax Period included in the Straddle Period and the denominator of which is the total number of days in the Straddle Period, and the amount of such Taxes attributable to any Post-Closing Tax Period included in a Straddle Period shall be the excess of the amount of the Taxes for the Straddle Period over the amount of Taxes attributable to the Pre-Closing Tax Period included in such Straddle Period.

6.3. Refunds. Any refunds of Taxes (including any interest paid thereon) for Pre-Closing Tax Periods received by any of the Acquired Entities or by Seller with respect to any of the Acquired Entities or credited to any of the Acquired Entities (“Seller’s Refunds”), shall be for the benefit of Seller, and Buyer shall cause the Acquired Entities to pay over to Seller any Seller’s Refunds promptly upon receipt thereof, provided, however, a Seller’s Refund shall be for the benefit of Buyer rather than Seller and shall not be paid to Seller, and if received by Seller or any of its Affiliates, shall be remitted to Buyer, to the extent that Seller’s Refund (i) was included as an asset in determining Net Working Capital, (ii) is attributable to the carry back of a loss or other Tax attribute from a Post-Closing Tax Period, provided that whenever possible, Buyer will elect not to carry back a loss or other Tax attribute to a Pre-Closing Tax Period, or (iii) arises from an adjustment that results in an increase in Taxes, or a reduction of Tax benefits, in a Post-Closing Tax Period. In addition, subject to the limitations contained herein, if the aggregate payments of estimated Income Taxes made before the Closing Date for all Pre-Closing Tax Periods included in all Straddle Periods of all the Acquired Entities exceed the aggregate liability for Income Taxes for all Pre-Closing Tax Periods included in all Straddle Periods of all the Acquired Entities, Buyer shall pay, or cause to be paid, such net excess amount to Seller promptly upon receiving the benefit of such net excess amount through a reduction of any Tax payment required to be made by the Acquired Entities for Post-Closing Tax Periods. Seller shall have the right, at its expense, to request that Buyer pursue any Seller’s Refund which Seller is entitled to

retain hereunder (including filing amended returns and applying for competent authority or analogous relief), provided, however, Buyer shall not be required to pursue Seller’s Refunds, and Seller shall not pursue, or permit to be pursued, Seller’s Refunds, if Buyer shall determine in its reasonable discretion that pursuing Seller’s Refunds will likely have an adverse effect on Buyer, the Acquired Entities or its other Affiliates in a Post-Closing Tax Period. In the case of a Seller’s Refund that is a credit to any of the Acquired Entities and that Seller is entitled to retain hereunder, Buyer shall cause such Acquired Entity to pay such Seller’s Refund to Seller promptly upon receipt of the benefit of such credit through a reduction in any Tax payment required to be made by any of the Acquired Entities after the Closing.

6.4. Audits.

(a) Buyer shall promptly notify Seller in writing upon receipt by Buyer or its Affiliates of notice of any pending or threatened Tax audit or assessment which would affect the indemnification obligations of Seller in respect of Pre-Closing Tax Periods, provided that the failure to give notice will not relieve Seller of its indemnification obligations except to the extent that its position is actually materially prejudiced as a result of the failure to give timely notice. Subject to Sections 6.4(c) and (d), Seller shall have the sole right, at its expense, to represent the interests of the Acquired Entities and to employ counsel of its choice in any Tax Proceeding relating to Pre-Closing Tax Periods (other than a Tax Proceeding involving a Straddle Period), provided that Seller has acknowledged in writing its indemnification obligation under Section 6.1(a) in respect of the Taxes at issue in such Tax Proceeding if such Tax Proceeding is resolved adversely, by notifying Buyer in writing within fifteen (15) days from the receipt from Buyer of the notice described in the first sentence of this Section 6.4(a) of its intention to assume control of the conduct of such Tax Proceeding. If a shorter response period is required by such notice, and Buyer has not received Seller’s notification by the time the response to the relevant Governmental Entity is required, Buyer may temporarily assume responsibility for such Tax Proceeding, but shall relinquish control to the Seller if the Seller satisfies the requirements of the preceding sentence in the manner and in the time frame specified therein. Buyer shall be entitled (at Buyer’s expense) to attend such Tax Proceeding (whether such Tax Proceeding is conducted in person, by telephone or otherwise) with its representatives and to receive copies of all written communications, materials and submissions related to such Tax Proceeding received from, or provided to, the Governmental Entity and Seller shall keep Buyer informed on a timely basis of all developments. If Seller declines to assume the control of such Tax Proceeding, Buyer shall have the right, at Seller’s expense, to assume control of the conduct and resolution of such Tax Proceeding. The preceding two sentences shall not apply to any Tax Proceeding involving Income Taxes of the Federal Tax Group, the Old Aleris Federal Tax Group, or State, Local and Foreign Tax Groups that include any entity other than an Acquired Entity.

(b) Buyer shall have the right, with counsel of its choice, to represent the interests of the Acquired Entities in any Tax Proceeding involving a Straddle Period of an Acquired Entity. Seller may participate in any such Tax Proceeding at its own expense and Seller shall be kept informed of the progress of such Tax Proceeding. Seller’s consent shall be required prior to the settlement of any Tax Proceeding relating to a Straddle Period, which consent shall not be unreasonably withheld (or delayed).

(c) In the event the resolution of all or a portion of a Tax Proceeding with respect to a Pre-Closing Tax Period the conduct of which is controlled by Seller could result in an increase in Taxes or a loss of Tax benefits in a Post-Closing Tax Period for any Acquired Entity, Seller shall control the conduct and resolution of such Tax Proceeding provided that Seller shall not settle or resolve such Tax Proceeding, if such settlement or resolution would have such effect, without the consent of the Buyer, which shall not be unreasonably withheld or delayed.

(d) In the event a Tax Proceeding involves Pre-Closing Tax Periods and Post-Closing Tax Periods and the parties are not able to separate the periods into separate Tax Proceedings, then Seller and Buyer shall jointly control the conduct and resolution of such Tax Proceeding or portion thereof. Each party shall be entitled to employ counsel of its choice. For the avoidance of doubt, the parties agree and acknowledge that this Section 6.4(d) shall not apply to a Tax Proceeding regarding Income Tax Returns of the Federal Tax Group, the Old Aleris Federal Tax Group, or State, Local and Foreign Tax Groups that include any entity other than an Acquired Entity or any similar group including the Buyer, the Acquired Entities or its other Affiliates for a Post-Closing Tax Period.

(e) If there is a dispute between Seller and Buyer regarding the conduct or resolution of any Tax Proceeding or portion thereof described in Section 6.4(d) or the resolution of any Tax Proceeding or portion thereof described in Section 6.4(b) or (c), such dispute shall be referred to the Tax Arbitrator. Each of Seller and Buyer shall present its position to the Tax Arbitrator, which shall decide which position shall be adopted. The Tax Arbitrator shall not be entitled to accept any other position, unless Seller and Buyer shall so agree in writing. The decision of the Tax Arbitrator shall be final and binding, and its fees and costs shall be paid one-half by Seller and one-half by Buyer.

6.5. Cooperation. After the Closing, Buyer and Seller shall promptly make available or cause to be made available to the other, as reasonably requested, and to any Governmental Entity, all information, records or documents relating to Tax liabilities, potential Tax liabilities, or refunds of or relating to the Acquired Entities for all Pre-Closing Tax Periods and shall preserve all such information, records and documents until the later of ten (10) years from the end of the calendar year in which the Closing occurs or the expiration of any applicable statute of limitations, including any extensions thereof. Buyer and Seller shall cooperate with respect to the filing of any Tax Return pursuant to Section 6.2. Buyer and Seller shall cooperate with each other with respect to any Tax Proceeding. Buyer shall, at Seller’s expense, prepare and provide to Seller any federal, state, local and foreign Tax information packages reasonably requested by Seller for Seller’s use in preparing its Tax Returns or those of the Acquired Entities which it is required to prepare pursuant to Section 6.2(a) or (b). Such Tax information packages shall be completed by Buyer and provided to Seller within 45 days after Seller’s request therefor. Except as otherwise provided in this Section 6.5, each party shall bear its own expenses in complying with the foregoing provisions. As soon as practicable after the Closing Date, but not later than thirty (30) days thereafter, Seller will cause to be delivered to Buyer all of the original books and records (including work papers) and Tax Returns of the Acquired Entities which are in the possession of Seller, its Affiliates or its accountants or other advisors, it being understood that (i) Seller shall be entitled to retain copies of any such Tax Return and (ii) Sellers shall not be required to deliver any Tax Returns which are Taxes Returns of the Federal Tax Group, the Old Aleris Federal Tax Group or State, Local and Foreign Tax Groups of that include any entity other than an Acquired Entity.

6.6. Coordination with Other Provisions. Notwithstanding anything in this Agreement to the contrary, procedural provisions of this Article VI shall govern all claims for indemnification with respect to Taxes.

6.7. Transfer Taxes. Each of Buyer and Seller shall assume liability for and pay 50 percent of all Transfer Taxes arising out of or in connection with the transactions effected pursuant to this Agreement as well as all out-of-pocket costs associated with the preparation and filing of the Tax Returns under this Section 6.7. Buyer shall timely file or cause to be filed all necessary documentation and Tax Returns with respect to such Transfer Taxes and Seller will cooperate with Buyer.

6.8. Period of Limitation. Any claim for indemnification for Taxes under this Article VI shall be brought prior to the expiration of the statute of limitations for the assessment of Taxes that are the subject of the indemnification claim.

6.9. Tax Sharing Agreements. Prior to the Closing, all Tax Sharing shall be terminated, and no additional payments shall be required to be made thereunder by any Acquired Entity.

6.10. Amended Returns. Buyer shall not file any amended Tax Return with respect to any Pre-Closing Tax Period without Seller’s written consent, excepted as otherwise required by Law.

6.11. Section 338 Elections. Seller shall cooperate with Buyer to cause an election to be made, at Buyer’s written request (each such request to be made within 90 days following the Closing Date), under Section 338(h)(10) of the Code with respect to any or all of the Acquired Entities, as designated by Buyer. Seller also shall cooperate with Buyer to cause elections, at Buyer’s written request (each such request to be made within 90 days following the Closing Date), with respect to any or all of the Acquired Entities, as designated by Buyer, under any state or local Law equivalent of Section 338(h)(10); provided that no election shall be made under Section 338(g) of the Code with respect to any Acquired Entity that is a Domestic Corporation within the meaning of Section 7701(a)(4) of the Code. Within 120 days after the Closing, the Buyer shall deliver to Seller a schedule (the “Proposed Section 338 Allocation Statement”) showing a proposed allocation for purposes of Section 338 of the Code (and the state and local equivalents thereof) of the “aggregate deemed sales price” of the assets of the Acquired Entities for which Section 338 Elections are made among the assets of the Acquired Entities, in accordance with applicable Treasury Regulations. The Seller shall have 30 days following receipt of the Proposed Section 338 Allocation Schedule to provide comments thereron and the parties shall work in good faith to reach agreement on any matters in dispute. In the event the dispute cannot be resolved it shall be referred to the Tax Arbitrator. Each of Seller and Buyer shall present its position to the Tax Arbitrator, which shall decide which position shall be adopted. The decision of the Tax Arbitrator shall be final and binding, and its fees and costs shall be paid one-half by Seller and one-half by Buyer. The Proposed Section 338 Allocation Statement as amended to reflect agreed or resolved changes, shall become the “Final Section 338 Allocation Statement”.

The Final Section 338 Allocation Statement shall be amended to reflect any adjustment to the Purchase Price hereunder. Seller and Buyer shall prepare and file, or cause to be prepared and filed, all Tax Returns consistent, and shall not take, or permit to be taken, any position in a Tax Proceeding inconsistent, with the Final Section 338 Allocation Statement as amended pursuant to the preceding sentence.

6.12. Closing Date Activities. Buyer agrees not to engage, and not to cause or permit any of the Acquired Entities to engage, in any transaction after the Closing on the Closing Date outside of the ordinary course of business and not otherwise contemplated by this Agreement. Notwithstanding anything to the contrary in this Agreement, Seller shall not be responsible for, and Buyer shall indemnify Seller, for any Taxes resulting from (i.e. that would not have been payable but for) the violation of this covenant or the covenant in Section 6.11 not to make an election under Section 338(g) of the Code with respect to any Acquired Entity that is a Domestic Corporation.

9.6. Procedure for Third Party Claims.

(a) If any third party shall notify any Party (the “Indemnitee”) with respect to any matter (a “Third Party Claim”) which may give rise to a claim for indemnification against any other Party (the “Indemnitor”) under this Article IX, then the Indemnitee shall promptly notify the Indemnitor thereof in writing; provided, however, that no delay on the part of the Indemnitee in notifying the Indemnitor shall relieve the Indemnitor from any obligation hereunder except to the extent the Indemnitor is actually and materially prejudiced thereby.

(b) The Indemnitor shall have the right, at its option, to assume the defense of any Third Party Claim with its own counsel. If the Indemnitor elects to assume the defense of such Third Party Claim as aforesaid, then:

(i) notwithstanding anything to the contrary contained in this Agreement, the Indemnitor shall not be required to pay or otherwise indemnify the Indemnitee against any attorneys’ fees incurred by the Indemnitee in connection with such Third Party Claim following the Indemnitor’s election to assume the defense of such Third Party Claim, unless (A) the Indemnitor fails to defend diligently the action or proceeding within 10 days after receiving notice of such failure from the Indemnitee; or (B) the Indemnitee reasonably shall have concluded (upon advice of its counsel) that (x) there may be one or more legal defenses available to such Indemnitee or other Indemnitees that are not available to the Indemnitor or (y) a conflict exists which makes representation of both the Indemnitor and the Indemnitee inappropriate under applicable standards of professional conduct; in the case of each of (A) or (B) above, the Indemnitor shall only be required to pay the fees of one counsel of the Indemnitee in each applicable country;

(ii) the Indemnitee shall make available to the Indemnitor all books, records and other documents and materials that are under the direct or indirect control of the Indemnitee or any of the Indemnitee’s agents and that are reasonably necessary for the defense of such Third Party Claim;

(iii) the Indemnitee shall otherwise cooperate as reasonably requested by the Indemnitor in the defense of such Third Party Claim;

(iv) the Indemnitee shall not admit any liability with respect to such Third Party Claim;

(v) the Indemnitor shall not, without the written consent of the Indemnitee, which shall not be unreasonably withheld or delayed, settle or

compromise any pending or threatened Claim in respect of which indemnification may be sought hereunder (whether or not the Indemnitee is an actual or potential party to such Claim) or consent to the entry of any judgment (A) which does not, to the extent that the Indemnitee or any of its Affiliates may have any liability with respect to such Claim, include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnitee of a written release of the Indemnitee and its Affiliates from all liability in respect of such Claim, (B) which includes any statement as to or an admission of fact, culpability or a failure to act, by or on behalf of the Indemnitee or any of its Affiliates, or (C) in any manner that involves any injunctive relief against the Indemnitee or any of its Affiliates or may materially and adversely affect the Indemnitee or any of its Affiliates; and

(vi) if the Indemnitor does not elect to assume the defense of such Third Party Claim within 30 days after receipt of notice from the Indemnitee as described above, then the Indemnitee shall proceed diligently to defend such Third Party Claim with the assistance of counsel reasonably satisfactory to the Indemnitor, provided, however, that the Indemnitee shall not settle, adjust or compromise such Third Party Claim, or admit any liability with respect to such Third Party Claim, without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld or delayed.

9.7. Indemnification Payments as Purchase Price Adjustment. Any payments made by Buyer or Seller under this Article IX shall be considered an adjustment to the Purchase Price.

9.8. Tax Claims. Notwithstanding anything to the contrary contained in this Article IX, the procedures with respect to any liabilities for Taxes as set forth in Article VI shall be governed by Article VI.

9.9. Exclusive Remedy. Except as set forth in Section 10.11 or in the case of fraud or intentional misrepresentation, from and after the Closing, the indemnification rights provided in this Article IX shall be the sole and exclusive remedy available to the Parties hereto with respect to any breach of the representations, warranties, covenants or agreements of the Parties in this Agreement.

9.10. Certain Additional Matters. The amount of any and all Losses under this Article IX shall be (i) determined net of any amounts recovered by an Indemnitee pursuant to any insurance policy, title insurance policy, indemnity, reimbursement arrangement or contract pursuant to which or under which such Indemnitee is a party or has rights, and (ii) if an Acquired Entity has not made a Section 338 Election, any Loss pursuant to Section 9.3 relating to such Acquired Entity shall be computed by taking into account the tax savings to such Acquired Entity resulting from the incurrence of the item for which indemnification is made, after first taking into account all other tax benefits available to such Acquired Entity.
