Ladies and Gentlemen:

Aleris Corporation, a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), an aggregate of [ ] shares of Common Stock, par value $0.01 per share, of the Company, and certain stockholders of the Company named in Schedule 2 hereto (the “Type 1 Selling Stockholders”) and certain stockholders of the Company named in Schedule 3 hereto (the “Type 2 Selling Stockholders” and, together with the Type 1 Selling Stockholders, the “Selling Stockholders”) propose to sell to the several Underwriters an aggregate of [ ] shares of Common Stock of the Company (collectively, the “Underwritten Shares”). In addition, the Selling Stockholders propose to sell, at the option of the Underwriters, up to an additional [ ] shares of Common Stock of the Company (collectively, the “Option Shares”). The Underwritten Shares and the Option Shares are herein referred to as the “Shares.” The shares of Common Stock of the Company to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock.”

The Company hereby confirms its agreement with the several Underwriters concerning the purchase and sale of shares to be sold by the Company and each Selling Stockholder hereby confirms its agreement with the several Underwriters concerning the purchase and sale of shares to be sold by such Selling Stockholder, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement (File No. 333-173721), including a prospectus, relating to the Shares. Such registration statement, as amended at the time it became effective, including the information,

if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Shares. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth in Annex B, the “Pricing Disclosure Package”): a Preliminary Prospectus dated , 2012 and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex B hereto.

“Applicable Time” means [ ] [A/P].M., New York City time, on [ ], 2012.

2. Purchase of the Shares by the Underwriters.

(a) The Company agrees to issue and sell, and each of the Selling Stockholders agrees, severally and not jointly, to sell, the Underwritten Shares to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase at a price per share (the “Purchase Price”) of $[ ] from the Company the respective number of Underwritten Shares set forth opposite such Underwriter’s name in Schedule 1 hereto (or such number increased as set forth in Section 12 hereof) and from each of the Selling Stockholders the number of Underwritten Shares (to be adjusted by you so as to eliminate fractional shares) determined by multiplying the aggregate number of Underwritten Shares to be sold by each of the Selling Stockholders as set forth opposite their respective names in Schedule 2 hereto by a fraction, the numerator of which is the aggregate number of Underwritten Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule 1 hereto and the denominator of which is the aggregate number of Underwritten Shares to be purchased by all the Underwriters hereunder.

In addition, each of the Selling Stockholders agrees, severally and not jointly, as and to the extent indicated in Schedule 2 hereto, to sell, the Option Shares to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase the Option Shares, severally and not jointly, from each Selling Stockholder at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten Shares but not payable on the Option Shares. If any Option Shares are to be purchased, the number of Option Shares to be purchased by each

Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 12 hereof) bears to the aggregate number of Underwritten Shares being purchased by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representatives in their sole discretion shall make. Any such election to purchase Option Shares shall be made in proportion to the maximum number of Option Shares to be sold by each Selling Stockholder as set forth in Schedule 2 hereto.

The Underwriters may exercise the option to purchase Option Shares at any time in whole, or from time to time in part, on or before the thirtieth day following the date of the Prospectus, by written notice from the Representatives to the Company and the Attorneys-in-Fact (as defined below). Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date or later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 12 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Company and the Selling Stockholders understand that the Underwriters intend to make a public offering of the Shares as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Shares on the terms set forth in the Prospectus. The Company and the Selling Stockholders acknowledge and agree that the Underwriters may offer and sell Shares to or through any affiliate of an Underwriter.

(c) Payment for the Shares shall be made by wire transfer in immediately available funds to the accounts specified by the Company and the Attorneys-in-Fact or any of them (with regard to payment to the Selling Stockholders), to the Representatives in the case of the Underwritten Shares, at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP at 10:00 A.M., New York City time, on [ ], 2012, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives, the Company and the Attorneys-in-Fact may agree upon in writing or, in the case of the Option Shares, on the date and at the time and place specified by the Representatives in the written notice of the Underwriters’ election to purchase such Option Shares. The time and date of such payment for the Underwritten Shares is referred to herein as the “Closing Date,” and the time and date for such payment for the Option Shares, if other than the Closing Date, is herein referred to as the “Additional Closing Date.”

Payment for the Shares to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against delivery to the Representatives for the respective accounts of the several Underwriters of the Shares to be purchased on such date or the Additional Closing Date, as the case may be, with any transfer taxes payable in connection with the sale of such Shares duly paid by the Company and the Selling Stockholders, as applicable. Delivery of the Shares shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Representatives shall otherwise instruct. The certificates for the Shares will be made available for inspection and packaging by the Representatives at the office of DTC or its designated custodian not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(d) Each of the Company and each Selling Stockholder acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Selling Stockholders with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Selling Stockholders or any other person. Additionally, none of the Representatives nor any other Underwriter is advising the Company, the Selling Stockholders or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company and the Selling Stockholders shall consult with their own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company or the Selling Stockholders with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company or the Selling Stockholders.

4. Representations and Warranties of the Selling Stockholders. Each of the Selling Stockholders (and in the case of clause (h), solely the Type 2 Selling Stockholders) severally and not jointly represents and warrants to each Underwriter and the Company that:

(a) Required Consents; Authority. All consents, approvals, authorizations and orders necessary for the execution and delivery by such Selling Stockholder of this Agreement and the Power of Attorney (the “Power of Attorney”) and the Custody Agreement (the “Custody Agreement”) hereinafter referred to, to the extent such Selling Stockholder is a party thereto, and for the sale and delivery of the Shares to be sold by

such Selling Stockholder hereunder, have been obtained except (i) for the registration of the Shares under the Securities Act, (ii) for such registration as is required under the Exchange Act, (iii) for such consents, approvals, authorizations, orders or qualifications as may be required by the Financial Industry Regulatory Authority, Inc. (“FINRA”), (iv) such as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Shares, (v) such as will have been obtained prior to the Closing Date and (vi) for such consents, approvals, authorizations, or orders as would not impair in any material respect the ability of such Selling Stockholder to execute, deliver and perform the transactions contemplated by this Agreement, the Custody Agreement and the Power of Attorney, to the extent a party thereto, and such Selling Stockholder has full right, power and authority to enter into this Agreement, the Power of Attorney and the Custody Agreement, to the extent such Selling Stockholder is a party thereto and to sell, assign, transfer and deliver the Shares to be sold by such Selling Stockholder hereunder; this Agreement, the Power of Attorney and the Custody Agreement have each been duly authorized, executed and delivered by such Selling Stockholder, to the extent such Selling Stockholder is a party thereto.

(b) No Conflicts. The execution, delivery and performance by such Selling Stockholder of this Agreement, the Power of Attorney and the Custody Agreement, to the extent such Selling Stockholder is a party thereto, the sale of the Shares to be sold by such Selling Stockholder and the consummation by such Selling Stockholder of the transactions contemplated herein or therein will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of such Selling Stockholder pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which such Selling Stockholder is a party or by which such Selling Stockholder is bound or to which any of the property or assets of such Selling Stockholder is subject, (ii) result in any violation of the provisions of the charter or by-laws or similar organizational documents of such Selling Stockholder or (iii) result in the violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory agency, except, in the case of clause (i) and (iii) above, for any breaches, defaults or violation that would not, individually or in the aggregate, have a material adverse effect on the ability of such Selling Stockholder to execute, deliver and perform the transactions contemplated by this Agreement, the Custody Agreement and the Power of Attorney, to the extent a party thereto.

(c) Title to Shares. Such Selling Shareholder has, and on the Closing Date, and any Additional Closing Date, will have, valid title to, or a valid “security entitlement” pursuant to Section 8-501 of the New York Uniform Commercial Code (the “NYUCC”) in respect of, the Shares to be sold by such Selling Stockholder free and clear of all security interests, claims, liens, equities or other encumbrances and the legal right and power, and all authorization and approval required by law, to enter into this Agreement, and to sell, transfer and deliver the Shares to be sold by such Selling Stockholder or a security entitlement in respect of such Shares. Assuming that each Underwriter acquires its interest in the Shares it has purchased under this Agreement from such Selling Stockholder without notice of any adverse claim (within the meaning of Section 8-105 of the NYUCC) with respect to the Shares, each Underwriter that has purchased such Shares

delivered on the Closing Date and any Additional Closing Date to DTC or other securities intermediary (within the meaning of Section 8-102(a)(14) of the NYUCC) by making payment therefor as provided herein, and that has such Shares credited by book entry to the securities account or accounts (within the meaning of Section 8-501(a) of the NYUCC) of such Underwriters maintained with DTC or such other securities intermediary will have acquired a security entitlement (within the meaning of 8-102(a)(17) of the NYUCC) to such Shares purchased by such Underwriter, and no action based on an adverse claim (within the meaning of Sections 8-102(a)(1) and 8-502 of the NYUCC) may be asserted against such Underwriter with respect to such Shares. For purposes of this representation, such Selling Shareholder may assume that when such payment, delivery (if necessary) and crediting occur, (i) such Shares will have been registered in the name of Cede or another nominee designated by DTC, in each case on the Company’s share registry in accordance with its certificate of incorporation, bylaws and applicable law, (ii) DTC will be registered as a “clearing corporation” (and thus is a “securities intermediary”) within the meaning of Section 8-102(a)(5) of the NYUCC and (iii) appropriate entries to the accounts of the several Underwriters on the records of DTC will have been made pursuant to the NYUCC.

(d) No Stabilization. Such Selling Stockholder has not taken and will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Shares.

(f) Issuer Free Writing Prospectus. Other than the Registration Statement, the Preliminary Prospectus and the Prospectus, such Selling Stockholder (including its agents and representatives, other than the Underwriters in their capacity as such) has not prepared, used, authorized, approved or referred to and will not prepare, use, authorize, approve or refer to any Issuer Free Writing Prospectus, other than (i) any document not constituting a prospectus pursuant to Section 2(a)(10)(a) of the Securities Act or Rule 134 under the Securities Act or (ii) the documents listed on Annex B hereto, each electronic road show and any other written communications approved in writing in advance by the Company and the Representatives.

(g) Registration Statement and Prospectus. As of the applicable effective date of the Registration Statement and any post-effective amendment thereto, the Registration Statement and any such post-effective amendment did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading; and as of the date of the Prospectus and any amendment or supplement thereto and as of the Closing Date and as of the Additional Closing Date, as the case may be, the Prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the representations and warranties set forth in this subsection apply only to statements or omissions made in reliance on and in conformity with the Selling Stockholder’s Information.

(h) Material Information. As of the date hereof, as of the Closing Date and as of the Additional Closing Date, as the case may be, the sale of the Shares by such Type 2 Selling Stockholder is not and will not be prompted by any material information concerning the Company which is not set forth in the Registration Statement, the Pricing Disclosure Package or the Prospectus.

Each of the Selling Stockholders represents and warrants that certificates in negotiable form representing all of the Shares to be sold by such Selling Stockholders hereunder other than any such Shares to be issued upon the exercise of Options, have been, and each of the Selling Stockholders who is selling Shares upon the exercise of Options represents and warrants that duly completed and executed irrevocable Option exercise notices, in the forms specified by the relevant Option Agreement, with respect to all of the Shares to be sold by such Selling Stockholders hereunder have been, placed in custody under a Custody Agreement relating to such Shares, in the form heretofore furnished to you, duly executed and delivered by such Selling Stockholder to Computershare Inc., as custodian (the “Custodian”), and that such Selling Stockholder has duly executed and delivered Powers of Attorney, to the extent such Selling Stockholder shall be a party thereto, in the form heretofore furnished to you, appointing the person or persons indicated in Schedule II hereto, and each of them, as such Selling Stockholder’s Attorneys-in-fact (the “Attorneys-in-Fact” or any one of them the “Attorney-in Fact”) with authority to execute and deliver this Agreement on behalf of such Selling Stockholder, to determine the purchase price to be paid by the Underwriters to the Selling Stockholders as provided herein, to authorize the delivery of the Shares to be sold by such Selling Stockholder hereunder, to authorize (if applicable) the exercise of the Options to be exercised with respect to the Shares to be sold by such Selling Stockholder hereunder and otherwise to act on behalf of such Selling Stockholder in connection with the transactions contemplated by this Agreement and the Custody Agreement.

Each of the Selling Stockholders specifically agrees that the Shares represented by the certificates or the irrevocable Option exercise notice, in either case held in custody for such Selling Stockholder under the Custody Agreement, are subject to the interests of the Underwriters hereunder, and that the arrangements made by such Selling Stockholder for such custody, and the appointment by such Selling Stockholder of the Attorneys-in-Fact by the Power of Attorney, are to that extent irrevocable. Each of the Selling Stockholders specifically agrees that the obligations of such Selling Stockholder hereunder shall not be terminated by operation of law, whether by the death or incapacity of any individual Selling Stockholder, or, in the case of an estate or trust, by the death or incapacity of any executor or trustee or the termination of such estate or trust, or in the case of a partnership, corporation or similar organization, by the dissolution of such partnership, corporation or organization, or by the occurrence of any other event. If any

individual Selling Stockholder or any such executor or trustee should die or become incapacitated, or if any such estate or trust should be terminated, or if any such partnership, corporation or similar organization should be dissolved, or if any other such event should occur, before the delivery of the Shares hereunder, certificates representing such Shares shall be delivered by or on behalf of such Selling Stockholder in accordance with the terms and conditions of this Agreement and the Custody Agreement, and actions taken by the Attorneys-in-Fact pursuant to the Powers of Attorney shall be as valid as if such death, incapacity, termination, dissolution or other event had not occurred, regardless of whether or not the Custodian, the Attorneys-in-Fact, or any of them, shall have received notice of such death, incapacity, termination, dissolution or other event.

flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or from any legal or governmental proceeding, order or decree, which loss or interference, individually or in the aggregate, has or would be reasonably likely to have a Material Adverse Effect.

9. Indemnification and Contribution.

(a) Indemnification of the Underwriters by the Company. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(b) Indemnification of the Underwriters by the Selling Stockholders. Each of the Selling Stockholders severally and not jointly agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above; provided that each Selling Stockholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission has been made in the Registration Statement (or any amendment thereto) including the Rule 430A Information, any preliminary prospectus, the Pricing Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus in reliance upon and in conformity with such Selling Stockholder’s Information; provided further, that the liability under this subsection of each Selling Stockholder shall be limited to an amount (the “Selling Stockholder Amount”) equal to the aggregate net proceeds after underwriting commissions and discounts, but before expenses, to such Selling Stockholder from the sale of Shares sold by such Selling Stockholder hereunder.

(c) Indemnification of the Company and the Selling Stockholders. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of the Selling Stockholders to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the third paragraph under the caption “Underwriting,” the information contained in the seventh and eighth paragraphs describing passive market making under the caption “Underwriting,” and the information contained in the paragraph describing the distribution of prospectuses by electronic means under the caption “Underwriting—Electronic Offer, Sale and Distribution of Shares.”

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 9, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the Indemnifying Person shall not relieve it from any liability

that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 9. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives, any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Stockholders shall be designated in writing by the Attorneys-in-Fact or any one of them. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement, unless such failure to reimburse the Indemnifying Person is based on a dispute with a good faith basis as to either the obligation of the Indemnifying Person arising under this Section 9 to indemnify the Indemnified Person or the amount of such obligation and the Indemnifying Person shall have notified the Indemnified Person of such good faith dispute prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(e) Contribution. If the indemnification provided for in paragraphs (a), (b) and (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company and the Selling Stockholders from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Stockholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Selling Stockholders or the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 9, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several in proportion to their respective purchase obligations hereunder and not joint. The Selling Stockholders’ obligations to contribute pursuant to this Section 9 are several in proportion to their respective Selling Stockholder Amounts and not joint, and shall be limited to an amount equal to the Selling Stockholder Amount.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

10. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

11. Termination.

(a) This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company and the Selling Stockholders, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date,

(i)(a) any of the Company or its subsidiaries shall have sustained any loss or interference with respect to its businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or any legal or governmental proceeding, which loss or interference, in the judgment of the Representatives, has had or has a Material Adverse Effect, or (b) there shall have been, in the judgment of the Representatives, any event or development that, individually or in the aggregate, has or could be reasonably likely to have a Material Adverse Effect such that in either case of (a) or (b) it would be impracticable or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Registration Statement, the Pricing Disclosure Package and the Prospectus;

(ii) trading in securities generally on the New York Stock Exchange or NASDAQ shall have been suspended or materially limited or minimum or maximum prices shall have been established on any such exchange or market;

(iii) a general moratorium on commercial banking activities shall have been declared by New York or United States authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred; or

(iv) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or any other national or international calamity or emergency or (C) any material adverse change in the financial markets of the United States which, in the case of (A), (B) or (C) above and in the judgment of the Representatives, makes it impracticable or inadvisable to proceed with the offering or the delivery of the Shares as contemplated by the Registration Statement, the Pricing Disclosure Package and the Prospectus.

(b) Termination of this Agreement pursuant to this Section 11 shall be without liability of any party to any other party except as provided in Section 13 hereof.

12. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company and the Selling Stockholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company and the Selling Stockholders may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Selling Stockholders or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 12, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company and the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company and the Selling Stockholders shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on the Additional Closing Date, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 12 shall be without liability on the part of the Company, except that the Company and the Selling Stockholders will continue to be liable for the payment of expenses as set forth in Section 13 hereof and except that the provisions of Section 9 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Selling Stockholders or any non-defaulting Underwriter for damages caused by its default.

13. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and the Selling Stockholders (with such expenses shared as between them in accordance with the terms of the Registration Rights Agreement) will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing the Underwriting Agreement; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the reasonable fees and expenses of counsel for the Underwriters in connection therewith); (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA; (ix) all out-of-pocket expenses incurred by the Company in connection with any “road show” presentation to potential investors (it being understood that the Underwriters, collectively, shall bear one-half of the costs associated with any aircraft chartered in connection with the road show); and (x) all expenses and application fees related to the listing of the Shares on the Exchange.

(b) If (i) this Agreement is terminated pursuant to Section 11(a)(i), (ii) the Company or the Selling Stockholders for any reason fail to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason permitted under Section 8 of this Agreement, the Company and the Selling Stockholders (with such expenses shared as between them in accordance with the terms of the Registration Rights Agreement) agree to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

14. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 9 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

15. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Selling Stockholders and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Selling Stockholders or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Selling Stockholders or the Underwriters.

16. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

Re:

Aleris Corporation—Initial Public Offering

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Aleris Corporation, a Delaware corporation (the “Company”) and the Selling Stockholders listed on Schedule 2 to the Underwriting Agreement, providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of common stock of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of ▇.▇. ▇▇▇▇▇▇ Securities LLC (“▇.▇. ▇▇▇▇▇▇”), on behalf of the Underwriters, the undersigned will not, during the period ending 180 days after the date of the prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or other

Exhibit A-1

wise transfer or dispose of, directly or indirectly, any shares of Common Stock, $0.01 per share par value, of the Company (the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any offer, sale, pledge or disposition, (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock without the prior written consent of ▇.▇. ▇▇▇▇▇▇, in each case other than any (A) Securities to be sold by the undersigned pursuant to the Underwriting Agreement, (B) transfers of shares of Common Stock as a bona fide gift or gifts, (C) distributions of shares of Common Stock to members, partners or stockholders of the undersigned, (D) transfers of shares of Common Stock to funds or other entities under common control or management with the undersigned, (E) transfers of shares of Common Stock to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned and (F) bona fide pledges of Common Stock by the undersigned pursuant to customary financing transactions entered into in the ordinary course of business; provided that (i) in the case of any transfer or distribution pursuant to clause (B), (C), (D) or (E) each recipient (if not already party to a lock-up letter similar to this Letter Agreement) shall execute and deliver to the Representatives a lock-up letter in the form of this paragraph and (ii) in the case of any pledge of Common Stock pursuant to clause (F), the pledgee shall, if such pledge is in existence, execute and deliver to the Representatives a lock-up letter in the form of this paragraph upon receipt of such Common Stock, and if such pledge occurs in the future, execute and deliver to the Representatives a lock-up letter in the form of this paragraph at the time such pledge is granted; provided, further, that, in the case of any transfer or distribution pursuant to clause (B), (C), (D) or (E), to the extent that any party (donor, donee, transferor or transferee) is required to make a filing under the Securities Exchange Act of 1934, as amended, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a Form 5 made after the expiration of the 180 day period referred to above), then the undersigned shall have delivered written notice to ▇.▇. ▇▇▇▇▇▇ no less than two business days prior to such transfer or distribution. If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any Company-directed Securities the undersigned may purchase in the Public Offering.

Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions imposed by this Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, in each case, unless ▇.▇. ▇▇▇▇▇▇ waives such extension in writing.

Exhibit A-2

Furthermore, the undersigned may sell shares of Common Stock, debt securities or preferred securities purchased by the undersigned on the open market following the Public Offering if (i) such sales are not required to be reported under Section 16 or Sections 13(d) or (g) of the Securities Exchange Act of 1934, as amended and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales.

Nothing in this Letter Agreement shall prohibit any party hereto from converting or exchanging any debt securities or preferred stock held by it into or for equity securities of the Company, which equity securities shall be subject to the terms of this Letter Agreement.

In addition, the restrictions described in this Letter Agreement shall not apply to tenders of shares of Common Stock, debt securities or preferred securities made in response to a bona fide third party take-over bid made to all holders of shares of Common Stock, debt securities or preferred securities, as applicable, or any other acquisition transaction whereby all or substantially all of the shares of Common Stock, debt securities or preferred stock are acquired by a third party. To the extent that ▇.▇. ▇▇▇▇▇▇ provides a consent described in paragraphs 2 or 3 of this letter to any Type 1 Selling Stockholder that is a signatory to a similar agreement to this Letter Agreement, ▇.▇. ▇▇▇▇▇▇ and the Company shall promptly notify the undersigned within 48 hours of such consent, which shall also be provided on a pro rata basis to the undersigned (such right to be consistent with the terms of the Registration Rights Agreement).

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if (i) the Company withdraws the Registration Statement prior to the execution of the Underwriting Agreement, (ii) the Company notifies the undersigned in writing that it does not intend to proceed with the Public Offering, (iii) the Underwriting Agreement does not become effective on or before June 15, 2012 (the “Underwriting Agreement Effective Date”), subject to the right of the Company on or before June 1, 2012 to extend the Underwriting Agreement Effective Date to July 16, 2012 or (iv) the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, then the undersigned shall be released from all obligations under this Letter Agreement. The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.

Exhibit A-3

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.


Very truly yours,
