Tranche upon one Business Days notice (or, in the case of a Mandatory Borrowing of Euro Rate Loans, two Business Days notice) pursuant to each Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on

any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code or any other relevant bankruptcy or insolvency laws
with respect to any Borrower), then each Lender with a Commitment under the relevant Tranche hereby agrees that it shall forthwith purchase (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received
from the relevant Borrowers on or after such date and prior to such purchase) from the relevant Swingline Lender such participations in the outstanding Swingline Loans of such Swingline Lender as shall be necessary to cause the Lenders with

respective Mandatory Borrowing) hereunder for each day thereafter.

(e) Notwithstanding anything to the contrary in Sections
2.01(a), (b), (c) or (d), Section 7.03 or elsewhere in this Agreement, upon at least 10 Business Days prior written notice to Aleris, the Administrative Agent shall have the right to establish reserves
in such amounts, and with respect to such matters, as the Administrative Agent in its Permitted Discretion shall deem necessary, against any Borrowing Base, including, without limitation, (i) an Unpaid Supplier Reserve and a Rent Reserve
against Eligible Inventory included in any Borrowing Base, (ii) Hedge Product Reserves and Bank Product Reserves and (iii) reserves for Priority Payables; provided, however, that the Administrative Agent may not implement
reserves with respect to matters which are already specifically reflected as ineligible Accounts or Inventory or criteria deducted in computing the cost or market value of Eligible Inventory or the Net Liquidation Value of Eligible Inventory; and
provided, further, that the Administrative Agent may only establish or increase a reserve (other than Rent Reserves, Hedge Product Reserves and Bank Product Reserves) after the Restatement Effective Date based on an event, condition or
other circumstance arising after the Restatement Effective Date or based on facts not known to the Administrative Agent as of the Restatement Effective Date. The amount of any reserve established by the Administrative Agent shall have a reasonable
relationship to the event, condition or other matter that is the basis for the reserve. Upon delivery of written notice to Aleris as provided above, the Administrative Agent shall be available to discuss the proposed reserve or increase, and Aleris
and its Subsidiaries may take such action as may be required so that the event, condition or matter that is the basis for such reserve or increase no longer exists, in a manner and to the extent reasonably satisfactory to the Administrative Agent in
the exercise of its Permitted Discretion. In no event shall such notice and opportunity limit the right of the Administrative Agent to establish or change such reserve, unless the Administrative Agent shall have determined in its Permitted
Discretion that the event, condition or other matter that is the basis for such new reserve or such change no longer exists or has otherwise been adequately addressed by the Borrowers.

(f) In the event any of the U.S. Borrowers, the Canadian Borrowers or the European Borrower is unable to comply with the conditions precedent to the
making of Revolving Loans or the issuance of Letters of Credit set forth in Section 7 (including, without limitation, the Borrowing Base limitations set forth in Section 7.03), (x) the U.S./European Lenders authorize the
Administrative Agent, for the account of the U.S./European Lenders, to make U.S. Borrower Revolving Loans to the U.S. Borrowers and (y) the Canadian Lenders authorize the Canadian Administrative Agent, for the account of the Canadian Lenders,
to make Canadian Revolving Loans to the Canadian Borrowers (each, an Agent Advance), which, in each case, (i) may only be made in U.S. Dollars as Base Rate Loans and (ii) may be made at any time or from time to time on

and (C) the date the Required Lenders instruct the Administrative Agent and the Canadian Administrative Agent to cease making Agent Advances (in each
case, the Agent Advance Period). Neither the Administrative Agent nor the Canadian Administrative Agent shall make any Agent Advance to the extent that at such time the amount of such Agent Advance (A) in the case of Agent
Advances made to the Canadian Borrowers, (I) when added to the aggregate outstanding amount of all other Agent Advances made to the Canadian Borrowers and the U.S. Borrowers at such time, would exceed 5% of the Combined U.S./Canadian Borrowing

amount of all other Agent Advances made to the U.S. Borrowers and the Canadian Borrowers at such time, would exceed 5% of the Combined U.S./Canadian Borrowing Base at such time (based on the Borrowing Base Certificate last delivered) less the
European U.S. Borrowing Base Usage at such time or (III) when added to the Aggregate U.S./European Exposure at such time (immediately prior to the incurrence of such Agent Advance), would exceed the Total U.S./European Commitment at such time. It is
understood and agreed that, subject to the requirements set forth above, Agent Advances may be made by the Administrative Agent or the Canadian Administrative Agent in the case of Canadian Borrower Obligations in their respective discretion to the
extent the Administrative Agent or the Canadian Administrative Agent deems such Agent Advances necessary or desirable (x) to preserve and protect the applicable Collateral, or any portion thereof, (y) to enhance the likelihood of, or
maximize the amount of, repayment of the Revolving Loans and other obligations of the Credit Parties hereunder and under the other Credit Documents or (z) to pay any other amount chargeable to or required to be paid by the Borrowers pursuant to
the terms of this Agreement, including payments of reimbursable expenses and other sums payable under the Credit Documents, and that the Borrowers shall have no right to require that any Agent Advances be made. Agent Advances will be deemed
U.S./European Borrower Swingline Loans (if made to the U.S. Borrowers) or Canadian Swingline Loans (if made to the Canadian Borrowers) for all purposes of this Agreement and shall be subject to refunding as a Mandatory Borrowing pursuant to
Section 2.01(d), in each case, notwithstanding (i) after giving effect thereto, the relevant Maximum Swingline Amount may be exceeded and (ii) the other conditions set forth in Sections 2.01(c) or (d), as
applicable may not be satisfied at such time.

2.02 Minimum Amount of Each Borrowing; Limitation on Euro Rate Loans. The aggregate

other matters required by the immediately preceding sentence to be specified in the Notice of Borrowing.

(b) (i) Whenever a Borrower
desires to make a Borrowing of (x) U.S. Borrower Swingline Loans or Canadian Swingline Loans hereunder, such Borrower shall give the relevant Swingline Lender, not later than 1:00 p.m. (New York time) on the date such relevant Swingline Loan is

(c) Without in any way limiting the obligation of any Borrower to confirm in writing any telephonic notice of any Borrowing or prepayment of Loans, the
Administrative Agent or the Canadian Administrative Agent, as applicable, or the relevant Swingline Lender (in the case of a Borrowing of Swingline Loans) may act without liability upon the basis of telephonic notice of such Borrowing or prepayment,
as the case may be, reasonably believed by the Administrative Agent or the Canadian Administrative Agent, as applicable, or such Swingline Lender, as the case, may be, in good faith to be from the president, the chief executive officer or a
Financial Officer of such Borrower, or from any other authorized officer of such Borrower designated in writing by such Borrower to the Administrative Agent or the Canadian Administrative Agent, as applicable, or the Swingline Lender, as the case
may be, as being authorized to give such notices, prior to receipt of written confirmation. In each such case, such Borrower hereby waives the right to dispute the Administrative Agents, the Canadian Administrative Agents or the
Swingline Lenders, as the case may be, record of the terms of such telephonic notice of such Borrowing or prepayment of Loans, as the case may be, absent manifest error.

the relevant Tranche of Loans will, subject to Section 16, make available its pro rata portion (determined in accordance with Section 2.07) of each such Borrowing requested to be made on such date (or, in the
case of Swingline Loans, the respective Swingline Lender shall make available the full amount thereof). All such amounts will be made available in the relevant Available Currency, and in immediately available funds at the Payment Office, and the
Administrative Agent or the Canadian Administrative Agent, as applicable, will make available to the respective Borrower or Borrowers (or to the relevant Swingline Lender, in the case of a Mandatory Borrowing at the Payment Office the aggregate of
the amounts so made available by the Lenders. Unless the Administrative Agent or the Canadian Administrative Agent, as applicable, shall have been notified by any Lender prior to the date of Borrowing that such Lender does not intend to make
available to the relevant Administrative Agent such Lenders portion of any Borrowing to be made on such date (other than in the circumstances described in Section 16), the relevant Administrative Agent may assume that such Lender
has made such amount available to the relevant Administrative Agent on such date of Borrowing and the relevant Administrative Agent may (but shall not be obligated to), in reliance upon such assumption, make available to the relevant Borrower or
Borrowers a corresponding amount. If such corresponding amount is not in fact made available to the relevant Administrative Agent by such Lender, the relevant Administrative Agent shall be entitled to recover such corresponding amount on demand from

Borrower or Borrowers, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the relevant Administrative Agent to such Borrower or Borrowers until the date such
corresponding amount is recovered by the relevant Administrative Agent, at a rate per annum equal to (i) if recovered from such Lender, the overnight Federal Funds Rate (or (x) in the case of Canadian Dollar Denominated Loans, the cost to
the Canadian Administrative Agent of acquiring overnight funds in Canadian Dollars, (y) in the case of Euro Denominated Loans, the cost to the relevant Administrative Agent of acquiring overnight funds in Euros or (z) in the case of Other
Foreign Currency Denominated Loans, the cost to the relevant Administrative Agent of acquiring overnight funds in the applicable Available Currency in which such Other Foreign Currency Denominated Loans were incurred) for the first three days and at
the interest rate otherwise applicable to such Loans for each day thereafter, and (ii) if recovered from the relevant Borrower or Borrowers, the rate of interest applicable to the respective Borrowing, as determined pursuant to
Section 2.08. Nothing in this Section 2.04 shall be deemed to relieve any Lender from its obligation to make Loans hereunder or to prejudice any rights which any Borrower may have against any Lender as a result of any failure
by such Lender to make Loans hereunder; provided that the funding of all U.S./European Revolving Loans which are also denominated in a Specified Foreign Currency shall also be subject to the provisions of Section 16.

Loans or Canadian Prime Rate Loans, as the case may be) made pursuant to one or more Borrowings under a single Tranche into a Borrowing or Borrowings of Bankers Acceptance Loans under such Tranche; provided that (i) Canadian Prime
Rate Loans may not be converted into Bankers Acceptance Loans if any Event of Default is in existence on the date of such conversion and the Canadian Administrative Agent, at the request of the Required Lenders, so notifies the relevant
Borrowers and (ii) Borrowings of Bankers Acceptance Loans resulting from this Section 2.06 shall be limited in number as provided in Section 2.02. Each such conversion shall be effected by the Canadian Borrowers by
giving the Canadian Administrative Agent at its Notice Office, prior to 11:00 a.m.(New York time), at least three Business Days prior to the date of the proposed conversion, a Notice of Conversion/Continuation specifying the Canadian Dollar
Denominated Loans to be so converted into Bankers Acceptance Loans, the Borrowing or Borrowings pursuant to which such Canadian Dollar Denominated Loans were made and the term of the proposed Borrowing of Bankers Acceptance Loans (which,

Bankers Acceptances by reason of circumstances affecting the Canadian money market generally or the relevant Available Currency (other than U.S. Dollars) is not available in sufficient amounts, as determined in good faith by the Administrative
Agent, acting reasonably, to fund any Borrowing of Bankers Acceptance Loans, Non-Dollar Denominated Loans, as the case may be, requested pursuant to Section 2.01;

then, and in any such event, such Lender (or the Administrative Agent, in the case of clauses (i) or (iv) above) shall promptly give notice (by telephone promptly confirmed in writing) to the affected
Borrower and, except in the case of clauses (i) and (iv) above, to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (w) in the case
of clause (i) above, (A) in the event Eurodollar Loans are so affected, Eurodollar Loans shall no longer be available until such time as the Administrative Agent notifies the affected Borrower and the Lenders that the circumstances giving
rise to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing or Notice of Conversion/Continuation given by any Borrower with respect to Eurodollar Loans which have not yet been incurred (including by way of

Euro Rate, (x) in the case of clause (ii) above, the Borrowers agree to pay to such Lender, upon such Lenders written request therefor, such additional amounts (in the form of an increased rate of, or a different method of

hereto), (y) in the case of clause (iii) above, the affected Borrower or Borrowers shall take one of the actions specified in Section 2.10(b) as promptly as possible and, in any event, within the time period required by law and
(z) in the case of clause (iv) above, Bankers Acceptance Loans or Loans in the relevant Available Currency, as applicable (exclusive of any such Loans, that have theretofore been funded), shall no longer be available until such time
as the Administrative Agent notifies the affected Borrower or Borrowers and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing or notice pursuant to
Section 2.03 given by the respective Borrower or Borrowers with respect to such Loans which have not been incurred shall be deemed rescinded by such Borrower or Borrowers. Each of the Administrative Agent and each Lender agrees that if
it gives notice to any Borrower of any of the events described in clause (i), (ii), (iii) or (iv) above, it shall promptly notify such Borrower and, in the case of any such Lender, the Administrative Agent, promptly after it becomes aware
that such event has ceased to exist.

(b) At any time that any Euro Rate Loan is affected by the circumstances described in
Section 2.10(a)(ii), the affected Borrower may and, in the case of a Euro Rate Loan

then being made initially or pursuant to a conversion, cancel such Borrowing (or the conversion thereof) by giving the Administrative Agent telephonic notice (confirmed in writing) on the same date on which such Borrower was notified by the affected
Lender or the Administrative Agent pursuant to Section 2.10(a)(ii) or (iii) or (y) if the affected Euro Rate Loan is then outstanding, upon at least three Business Days written notice to the Administrative Agent,
(A) in the case of a Eurodollar Loan, require the affected Lender to convert such Eurodollar Loan into a Base Rate Loan or (B) in the case of any Non-Dollar Denominated Euro Rate Loan, repay such affected Non-Dollar Denominated Euro Rate

Borrowers may, in lieu of taking the actions described above, maintain such Non-Dollar Denominated Euro Rate Loan outstanding, in which case, the relevant Euro Rate shall be determined on the basis provided in the proviso to the
definition of the relevant Euro Rate unless the maintenance of such Non-Dollar Denominated Euro Rate Loan outstanding on such basis would not stop the conditions described in Section 2.10(a)(iii) from existing (in which case the actions
described above, without giving effect to this proviso, shall be required to be taken) and (ii) if more than one Lender is affected at any time, then all affected Lenders must be treated the same pursuant to this Section 2.10(b).

(c) If any Lender reasonably determines that after the Restatement Effective Date the introduction of or any change in any applicable law
or governmental rule, regulation, order, guideline, directive or request (whether or not having the force of law) concerning capital adequacy, or any change in interpretation or administration thereof by the NAIC or any Governmental Authority,
central bank or comparable agency charged with the administration thereof, will have the effect of increasing the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender based on the
existence of such Lenders Commitments hereunder or its obligations hereunder, then each affected Borrower agrees to pay to such Lender, upon its written demand therefor, such additional amounts as shall be required to compensate such Lender or
such other corporation for the increased cost to such Lender or such other corporation or the reduction in the rate of return to such Lender or such other corporation as a result of such increase of capital. In determining such additional amounts,
each Lender shall act reasonably and in good faith and shall use averaging and attribution methods which are reasonable, provided that such Lenders determination of compensation owing under this Section 2.10(c) shall, absent
manifest error, be final and conclusive and binding on all the parties hereto. Each Lender, upon determining that any additional amounts will be payable pursuant to this Section 2.10(c), shall give prompt written notice thereof to each
affected Borrower, which notice shall show in reasonable detail the basis for calculation of such additional amounts.

(d) Failure or delay
on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lenders right to demand such compensation; provided that (x) the affected Borrower or Borrowers shall not be required
to compensate a Lender pursuant to this Section 2.10 for any increased costs or reductions incurred more than 180 days prior to the date on which such Lender notifies the Borrowers of the change in law or other circumstance described in
Section 2.10(a)(ii) or 2.10(c) giving rise to such increased costs or reductions and of such Lenders intention to claim compensation therefor and

(y) if such change in law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to
include the period of retroactive effect thereof.

2.11 Compensation. Each Borrower agrees to compensate each Lender, upon its
written request (which request shall set forth in reasonable detail the basis for requesting such compensation), for all losses, expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the
liquidation or reemployment of deposits or other funds required by such Lender to fund its Bankers Acceptance Loans, or Euro Rate Loans but excluding loss of anticipated profits and Mandatory Costs) which such Lender may sustain: (i) if
for any reason (other than a default by such Lender or the Administrative Agent) a Borrowing of, or conversion from or into, Euro Rate Loans or Bankers Acceptances Loans does not occur on a date specified therefor in a Notice of Borrowing or
Notice of Conversion/Continuation (whether or not withdrawn by the applicable Borrower or Borrowers or deemed withdrawn pursuant to Section 2.10(a)); (ii) if any prepayment or repayment (including any prepayment or repayment made

Period with respect thereto; (iii) if any repayment (including any repayment made pursuant to Sections 5.01 or 5.02 or as a result of an acceleration of the Loans pursuant to Section 11 or as a result of the
replacement of a Lender pursuant to Sections 2.13 or 13.12(d)) of any Bankers Acceptance Loan occurs on a date which is not the maturity date of the respective Bankers Acceptance Loan, as the case may be; (iv) if any
prepayment of any of its Euro Rate Loans or Bankers Acceptance Loans is not made on any date specified in a notice of prepayment given by any Borrower; or (v) as a consequence of (x) any other default by any Borrower to repay Euro
Rate Loans or Bankers Acceptance Loans when required by the terms of this Agreement or any Note or B/A Instrument held by such Lender or (y) any election made pursuant to Section 2.10(b). Any Lenders or the
Administrative Agents determination of compensation owing to it under this Section 2.11 shall, absent manifest error, be final and conclusive and binding on all the parties hereto.

Administrative Agent to the extent not already reflected on Schedule II, one or more lending offices (which, for this purpose, may include Affiliates of the respective Lender) for the various Loans made, and Letters of Credit participated in,
by such Lender (including, in the case of Canadian Lenders, by designating a separate lending office (or Affiliate) to act as such with respect to Dollar Denominated Loans and Letter of Credit Outstandings versus Non-Dollar Denominated Loans;
provided that, for designations made after the Restatement Effective Date (unless such designation is made after the occurrence of a Conversion Event), to the extent such designation shall result in increased costs under
Section 2.10, 3.06 or 5.04 in excess of those which would be charged in the absence of the designation of a different lending office (including a different Affiliate of the respective Lender), then the Borrowers shall not
be obligated to pay such excess increased costs (although the Borrowers, in accordance with and pursuant to the other provisions of this Agreement, shall be obligated to pay the costs which would apply in the absence of such designation and any
subsequent increased costs of the type described above resulting from changes after the date of the respective designation). Each lending office and Affiliate of any Lender designated as provided above shall, for all purposes of this Agreement, be
treated in the same manner as the



-93-

respective Lender (and shall be entitled to all indemnities and similar provisions in respect of its acting as such hereunder).

(b) Each Lender agrees that on the occurrence of any event giving rise to the operation of Section 2.10(a)(ii) or (iii),
Section 2.10(c), Section 3.06 or Section 5.04 with respect to such Lender, it will, if requested by any Borrower, use reasonable efforts to designate another lending office for any Loans or Letters of Credit
affected by such event, provided that such designation is made on such terms that would not subject such Lender to any material unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender in any material respect,
with the object of avoiding or mitigating the consequence of the event giving rise to the operation of such Section. The Borrowers hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation.
Nothing in this Section 2.12(b) shall affect or postpone any of the obligations of the Borrowers or the right of any Lender provided in Sections 2.10, 3.06 and 5.04.

Commitment to occur on the date set forth in such Incremental Commitment Agreement, which date in any event shall be no earlier than the date on which (w) all fees required to be paid in connection therewith at the time of such effectiveness
shall have been paid (including, without limitation, any agreed upon up-front or arrangement fees owing to the Administrative Agent (or any affiliate thereof)), (x) all Incremental Commitment Requirements are satisfied, (y) all other
conditions set forth in this Section 2.15 shall have been satisfied, and (z) all other conditions precedent that may be set forth in such Incremental Commitment Agreement shall have been satisfied. The Administrative Agent shall
promptly notify each Lender as to the effectiveness of each Incremental Commitment Agreement, and at such time, (i) the Total Commitment (and the Total U.S./European Commitment and/or Total Canadian Commitment, as applicable) under, and for all
purposes of, this Agreement shall be increased by the aggregate amount of such Incremental Commitments, (ii) if the Total U.S./European Commitment is then being increased and the relevant Incremental Commitment Agreement so provides, the Total
European Sub-Commitment shall be increased by the amount specified in such Incremental Commitment Agreement (not to exceed the amount of the related Incremental Commitment); (iii) Schedule I-A shall be deemed modified to reflect the
revised Commitments of the affected Lenders and (iv) to the extent requested by any Incremental Lender, Revolving Loan Notes will be issued, at the expense of each applicable Borrower, to such Incremental Lender in conformity with the
requirements of Section 2.05.

(c) At the time of any provision of Incremental Commitments pursuant to this
Section 2.15, the Borrowers under the relevant Tranche or Tranches shall, in coordination with the Administrative Agent, repay outstanding Revolving Loans of certain of the Lenders under the relevant Tranche or Tranches, and incur
additional Revolving Loans from certain other Lenders under the relevant Tranche or Tranches (including the Incremental Lenders), even though as a result thereof such new Loans (to the extent required to be maintained as Euro Rate Loans) may have a
shorter Interest Period than the then outstanding Borrowings of such Loans, in each case to the extent necessary so that all of the Lenders under the relevant Tranche or Tranches participate in each outstanding Borrowing of Revolving Loans under the
relevant Tranche or Tranches pro rata on the basis of their respective Commitments under the relevant Tranche or Tranches (after giving effect to any increase in the Total Commitment (and the Total U.S./European Commitment and/or Total
Canadian Commitment, as applicable) pursuant to this Section 2.15) and with each affected Borrower under the relevant Tranche being obligated to pay to the respective Lenders any costs of the type referred to in Section 2.11
and such amounts, as reasonably determined by the respective Lenders, to compensate them for funding the various

Revolving Loans during an existing Interest Period (rather than at the beginning of the respective Interest Period, based upon rates then applicable thereto)
in connection with any such repayment and/or incurrence. All determinations by any Lender pursuant to the preceding sentence shall, absent manifest error, be final and conclusive and binding on all parties hereto. Without limiting the obligations of
the Borrowers under this Section 2.15(c), the Administrative Agent and the Lenders agree that they will use their commercially reasonable efforts to attempt to minimize the costs of the type referred to in Section 2.11 that
the Borrowers would otherwise incur in connection with the implementation of any Incremental Commitments.

2.16 Interest Act (Canada);
Criminal Rate of Interest; Nominal Rate of Interest. (a) Notwithstanding anything to the contrary contained in this Agreement or in any other Credit Document, solely to the extent that a court of competent jurisdiction finally determines
that the calculation or determination of interest or any fee payable by the Canadian Borrowers in respect of the ABL Obligations pursuant to this Agreement and the other Credit Documents shall be governed by the laws of any province of Canada or the
federal laws of Canada, in no event shall the aggregate interest (as defined in Section 347 of the Criminal Code, R.S.C. 1985, c. C-46, as the same shall be amended, replaced or re-enacted from time to time) payable by the Canadian
Borrowers to the Agents or any Lender under this Agreement or any other Credit Document exceed the effective annual rate of interest on the credit advances (as defined in that section) under this Agreement or such other Credit Document
lawfully permitted under that section and, if any payment, collection or demand pursuant to this Agreement or any other Credit Document in respect of interest (as defined in that section) is determined to be contrary to the provisions of
that section, such payment, collection or demand shall be deemed to have been made by mutual mistake of the Agents, the Lenders and the Canadian Borrowers and the amount of such payment or collection shall be refunded by the relevant Agents and
Lenders to the Canadian Borrowers. For the purposes of this Agreement and each other Credit Document to which the Canadian Borrowers is a party, the effective annual rate of interest payable by the Canadian Borrowers shall be determined in
accordance with generally accepted actuarial practices and principles over the term of the loans on the basis of annual compounding for the lawfully permitted rate of interest and, in the event of dispute, a certificate of a Fellow of the Canadian
Institute of Actuaries appointed by the for the account of the Canadian Borrowers will be conclusive for the purpose of such determination in the absence of evidence to the contrary.

(b) For the purposes of the Interest Act (Canada) and with respect to Canadian Credit Parties only:

(i) whenever any interest or fee payable by the Canadian Borrowers is calculated using a rate based on a year of 360 days or 365 days, as
the case may be, the rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (x) the applicable rate based on a year of 360 days or 365 days, as the case may be, (y) multiplied by the actual number
of days in the calendar year in which such rate is to be ascertained and (z) divided by 360 or 365, as the case may be; and

(ii) all calculations of interest payable by the Canadian Borrowers under this Agreement or any other Credit Document are to be made on the basis of the nominal interest rate described herein and therein and not on the basis of effective
yearly rates or on any other basis which gives effect to the principle of deemed reinvestment of interest.

The parties hereto acknowledge that there is a material difference between the stated nominal interest rates and the effective yearly rates of interest and
that they are capable of making the calculations required to determine such effective yearly rates of interest.

2.17 Canadian
Lenders. (a) So long as no Significant Event of Default is in existence and no Conversion Event has occurred, each Canadian Lender shall at all times be a Canadian Resident or, at its option, such Canadian Lender shall designate an
Affiliate of such Lender which is a Canadian Resident (which Affiliate shall be a signatory to this Agreement and be listed on Schedule I-B hereto, or shall become a party hereto by signing an assumption agreement in form and substance
reasonably satisfactory to the Canadian Administrative Agent) to act as a Canadian Lender hereunder, in which case the Affiliate so designated as a Canadian Lender hereunder shall be required to be satisfactory to (and approved by) the Canadian
Administrative Agent and shall at all times hold the Canadian Commitment (and all extensions of credit pursuant thereto) of the respective Canadian Lender. To the extent legally entitled to do so, the Canadian Administrative Agent and each Canadian
Lender shall, upon written request by any Canadian Borrower, deliver to such Canadian Borrower or the applicable taxing authority, any form or certificate required in order that any payment by any Canadian Borrower under this Agreement may be made
free and clear of, and without deduction or withholding for or on account of, any Taxes, provided that (x) in determining the reasonableness of such a request such Person shall be entitled to consider the cost (to the extent unreimbursed
by the Canadian Borrower) which would be imposed on such Person of complying with such request, and (y) nothing in this Section 2.17(a) shall require a Lender to disclose any confidential information (including, without limitation,
its tax returns or its calculations).

(b) A Canadian Lender may change its Affiliate acting as Canadian Lender hereunder but only pursuant
to an assignment in form and substance reasonably satisfactory to the Canadian Administrative Agent (with the consent of the Administrative Agent), where the relevant assignee represents and warrants, unless a Significant Event of Default is in
existence or a Conversion Event has occurred, that it is an Affiliate of the relevant Canadian Lender and represents and warrants that it is a Canadian Resident and will act directly as a Canadian Lender with respect to the Canadian Commitment of
the relevant Canadian Lender.

(c) In connection with any assignment pursuant to Section 2.13 or 13.04 of all or any
part of the Canadian Commitment of any Canadian Lender the Assignment and Assumption Agreement shall, unless a Significant Event of Default is in existence or a Conversion Event has occurred, contain the representation and warranties specified in
the Assignment and Assumption Agreement including that it is a Canadian Resident.

(d) The foregoing shall in no event limit the sales or
purchases of participations in Canadian Revolving Loans after the occurrence of a Conversion Event or a Significant Event of Default.

2.18
Provisions Regarding Bankers Acceptances, Drafts, etc. The parties hereto agree that the provisions of Schedule III shall apply to all Bankers Acceptances, Bankers Acceptance Loans, Drafts and B/A Equivalent Notes
created hereunder, and that the provisions of Schedule III shall be deemed incorporated by reference into this Agreement as if such provisions were set forth in their entirety herein.

2.19 U.S./European Lenders. Each U.S./European Lender party hereto on the Restatement Effective
Date represents that it is a Swiss Qualifying Bank or a Swiss Non-Qualifying Bank as further indicated on Schedule I-C. Any Lender which ceases to be a Swiss Qualifying Bank shall promptly notify Aleris that it has ceased to be a Swiss
Qualifying Bank. If as a result of such event the number of Swiss Non-Qualifying Banks under this Agreement exceeds the number ten, then, so long as no Significant Event or Default is in existence, Aleris shall have the right to request that the
relevant Lender assign or transfer by novation all of its rights and obligations under this Agreement to an Eligible Transferee qualifying as a Swiss Qualifying Bank or another Lender qualifying as a Swiss Qualifying Bank, all in accordance with
Section 13.04. The Administrative Agent shall have no responsibility for determining whether or not an entity is a Swiss Qualified Bank, but shall track the number of U.S./European Lenders from time to time that were unable to represent
that they were Swiss Qualifying Banks in order to determine whether the number of Swiss Non-Qualifying Banks under this Agreement exceeds the number ten; provided that the Administrative Agent shall have no liability for any determinations
made hereunder unless such liability arises from its gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a non-appealable decision).

SECTION 3. Letters of Credit.

Letters of Credit issued for the account of the European Borrower) or the Canadian Commitments (in the case of any Letters of Credit issued for the account of the Canadian Borrowers), as applicable, and shall be participated in (as more fully

terms and conditions set forth herein, each Issuing Lender agrees that it will, at any time and from time to time on and after the Restatement Effective Date and prior to the 30th day prior to the Final Maturity Date, following its receipt of the
respective Letter of Credit Request, issue for account of the respective Account Party, one or more Letters of Credit as are permitted to remain outstanding hereunder without giving rise to a Default or an Event of Default, provided that no
Issuing Lender shall be under any obligation to issue any Letter of Credit of the types described above if at the time of such issuance:

(i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain such Issuing Lender from issuing such Letter of Credit or any requirement of law

effect with respect to such Issuing Lender as of the date hereof and which such Issuing Lender reasonably and in good faith deems material to it; or

(ii) such Issuing Lender shall have received from any Borrower, any other Credit Party or the Required Lenders prior to the issuance of such Letter of Credit notice of the type described in the second sentence of
Section 3.03(b).

Letter of Credit) shall constitute a Letter of Credit for all purposes of this Agreement and shall be deemed issued on the Restatement Effective Date.

(i) no Letter of Credit shall be issued the Stated Amount of which, when added to the Letter of Credit Outstandings (for this purpose, using the Dollar Equivalent of all amounts denominated in a currency other than U.S. Dollars) (exclusive of

Credit shall be extendible (including pursuant to an automatic extension provision on terms satisfactory to the applicable Issuing Lender) for successive periods of up to 12 months for each such extension and (B) the day that is five Business
Days prior to the Final Maturity Date.

3.03 Letter of Credit Requests; Minimum Stated Amount. (a) Whenever the respective
Account Parties desire that a Letter of Credit be issued for their account, the respective Account Parties shall give the Administrative Agent and the relevant Issuing Lender at least two Business Days (or such shorter period as is acceptable
to such Issuing Lender) written notice thereof (including by way of facsimile). Each notice shall be in the form of Exhibit C, appropriately completed (each, a Letter of Credit Request) to specify: (i) the name of the

(b) The making of each Letter of Credit Request
shall be deemed to be a representation and warranty by the applicable Borrowers to the Lenders that such Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.02. Unless the respective
Issuing Lender has received notice from any Borrower, any other Credit Party or the Required Lenders before it issues a Letter of Credit that one or more of the conditions specified in Section 6 or 7 are not then satisfied, or
that the issuance of such Letter of Credit would violate Section 3.02, then such Issuing Lender shall, subject to the terms and conditions of this Agreement, issue the requested Letter of Credit for the account of the respective Account
Parties in accordance with such Issuing Lenders usual and customary practices. Upon the issuance of or modification or amendment to any standby Letter of Credit, each Issuing Lender shall promptly notify the respective Account Parties and the
Administrative Agent in writing of such issuance, modification or amendment and such notice shall be accompanied by a copy of such Letter of Credit or the applicable modification or amendment thereto, as the case may be. Promptly after receipt of
such notice the Administrative Agent shall notify the L/C Participants, in writing, of such issuance, modification or amendment.

Amounts shown on Schedule IV) shall not be less



-102-



---

than $50,000 (or the equivalent amount thereof in the applicable Available Currency) or such lesser amount as is acceptable to the applicable Issuing Lender.

3.04 Letter of Credit Participations. (a) Immediately upon the issuance by an Issuing Lender of any Letter of Credit, such
Issuing Lender shall be deemed to have sold and transferred to each Lender in the applicable Tranche, and each such Lender (in its capacity under this Section 3.04, each, an L/C Participant) shall be deemed irrevocably
and unconditionally to have purchased and received from such Issuing Lender, without recourse or warranty, an undivided interest and participation, to the extent of such L/C Participants Facility Percentage in such Letter of Credit, each
Drawing or payment made thereunder and the obligations of the respective Account Parties under this Agreement with respect thereto (although Letter of Credit Fees shall be payable directly to the Administrative Agent for the account of the
respective Lenders as provided in Section 4.01(b) and the L/C Participants shall have no right to receive any portion of any Facing Fees with respect to any such Letters of Credit), and any security therefor or guaranty pertaining
thereto. Upon any change in the Commitments of any Tranche and, as a result thereof, the Facility Percentages of the applicable Tranche, of the respective Lenders pursuant to Section 2.19 or 13.04, it is hereby agreed that, with
respect to all outstanding Letters of Credit and Unpaid Drawings relating thereto, there shall be an automatic adjustment to the participations pursuant to this Section 3.04 to reflect the new Facility Percentages of the respective
Lenders of the applicable Tranche (or in the circumstances provided in the proviso to the immediately preceding sentence, the Percentages of the respective Lenders). With respect to each Letter of Credit from time to time outstanding, the percentage
participations therein of the various Lenders calculated as provided above in this Section 3.04(a) (including as provided in the proviso to the immediately preceding sentence) are herein called the L/C Participation
Percentages of the various Lenders in such Letters of Credit.

(b) In determining whether to pay under any Letter of Credit, no
Issuing Lender shall have any obligation relative to the other Lenders other than to confirm that any documents required to be delivered under such Letter of Credit appear to have been delivered and that they appear to substantially comply on their
face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by an Issuing Lender under or in connection with any Letter of Credit issued by it shall not create for such Issuing Lender any resulting liability to the
Account Parties, any other Credit Party, any Lender or any other Person unless such action is taken or omitted to be taken with bad faith, gross negligence, or willful misconduct on the part of such Issuing Lender (as determined by a court of
competent jurisdiction in a final and non-appealable decision).

(c) In the event that an Issuing Lender makes any payment under any Letter
of Credit issued by it and the respective Account Parties shall not have reimbursed such amount in full to such Issuing Lender pursuant to Section 3.05(a), such Issuing Lender shall promptly notify the Administrative Agent, which shall
promptly notify each relevant L/C Participant of such failure, and each such L/C Participant shall promptly and unconditionally pay to such Issuing Lender the amount of such L/C Participants L/C Participation Percentage of such unreimbursed
payment in the relevant Available Currency in same day funds. If the Administrative Agent so notifies, prior to 12:00 noon (New York time) on any Business Day, any L/C Participant required to fund a payment under a Letter of Credit, such L/C
Participant shall make available to the applicable Issuing Lender in the relevant Available Currency such



-103-



---

L/C Participants L/C Participation Percentage of the amount of such payment on such Business Day in same day funds. If and to the extent such L/C
Participant shall not have so made its L/C Participation Percentage of the amount of such payment available to the applicable Issuing Lender, such L/C Participant agrees to pay to such Issuing Lender, forthwith on demand such amount, together with
interest thereon, for each day from such date until the date such amount is paid to such Issuing Lender at the overnight Federal Funds Rate for the first three days and at the interest rate applicable to Revolving Loans that are maintained as Base
Rate Loans for each day thereafter. The failure of any such L/C Participant to make available to an Issuing Lender its L/C Participation Percentage of any payment under any Letter of Credit issued by such Issuing Lender shall not relieve any such
other L/C Participant of its obligation hereunder to make available to such Issuing Lender its L/C Participation Percentage of any payment under any Letter of Credit on the date required, as specified above, but no such L/C Participant shall be
responsible for the failure of any such other L/C Participant to make available to such Issuing Lender such other L/C Participants L/C Participation Percentage of any such payment.

(d) Whenever an Issuing Lender receives a payment of a reimbursement obligation (or interest thereon) as to which it has received any payments from the
respective L/C Participants pursuant to clause (c) above, such Issuing Lender shall pay to each such L/C Participant which has paid its L/C Participation Percentage thereof in the relevant Available Currency and in same day funds, an amount
(net of any interest owing to such Issuing Lender with respect to such reimbursement obligation) equal to such L/C Participants share (based upon the proportionate aggregate amount originally funded by such L/C Participant to the aggregate
amount funded by all such L/C Participants) of the principal amount of such reimbursement obligation and interest thereon (accruing after the funding of the respective participations) so received by the Issuing Lender.

(e) Upon the request of any L/C Participant, each Issuing Lender shall furnish to such L/C Participant copies of any standby Letter of Credit issued by
it and such other documentation as may reasonably be requested by such L/C Participant.

(f) The obligations of the L/C Participants to
make payments to each Issuing Lender with respect to Letters of Credit shall be irrevocable and not subject to any qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all
circumstances, including, without limitation, any of the following circumstances:

(i) any lack of validity or
enforceability of this Agreement or any of the other Credit Documents;

(ii) the existence of any claim, setoff, defense or
other right which Aleris or any of its Subsidiaries may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent,
any L/C Participant, or any other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between Aleris or any Subsidiary of
Aleris and the beneficiary named in any such Letter of Credit);



-104-



---

(iii) any draft, certificate or any other document presented under any Letter of Credit
proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(iv) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Credit Documents; or

(v) the occurrence of any Default or Event of Default.

3.05 Agreement to Repay Letter of Credit Drawings. (a) Subject to Section 3.05(b), (i) the U.S. Borrowers hereby jointly and severally agree (with respect to the U.S. Letters of Credit),
(ii) the Canadian Borrowers jointly and severally agree (with respect to the Canadian Letters of Credit) and (iii) the European Borrower agrees (with respect to the European Letters of Credit) to reimburse each Issuing Lender by making
payment to the Administrative Agent in the relevant Available Currency in immediately available funds at the Payment Office for any payment or disbursement made by such Issuing Lender under any Letter of Credit issued by it (each such amount, so
paid until reimbursed by the applicable Account Party, an Unpaid Drawing), not later than one Business Day following receipt by the applicable Account Party of notice of such payment or disbursement (provided that no such
notice shall be required to be given if a Default or an Event of Default under Section 11.05 shall have occurred and be continuing, in which case the Unpaid Drawing shall be due and payable immediately without presentment, demand,
protest or notice of any kind (all of which are hereby waived by the Borrowers)), with interest on the amount so paid or disbursed by such Issuing Lender, to the extent not reimbursed prior to 12:00 noon (New York time) on the date of such payment
or disbursement, from and including the date paid or disbursed to but excluding the date such Issuing Lender was reimbursed by the respective Account Parties therefor at a rate per annum equal to the Base Rate in effect from time to time plus
the Applicable Margin as in effect from time to time for Revolving Loans that are maintained as Base Rate Loans; provided, however, to the extent such amounts are not reimbursed prior to 12:00 noon (New York time) on the third Business
Day following the receipt by the respective Account Parties of notice of such payment or disbursement or following the occurrence of a Default or an Event of Default under Section 11.05, interest shall thereafter accrue on the amounts so
paid or disbursed by such Issuing Lender (and until reimbursed by the respective Account Party) at a rate per annum equal to the rate otherwise applicable to the respective Unpaid Drawing as provided above, plus 2%, with all such interest
payable pursuant to this Section 3.05 to be payable on demand. Notwithstanding anything to the contrary in the preceding sentence, the relevant Account Party may, subject to the conditions to borrowing set forth herein, request in
accordance with Section 2.03 that such payment be financed with a Revolving Loan or a Swingline Loan, in an equivalent amount and, to the extent so financed, such Account Partys obligation to make such reimbursement shall be
discharged and replaced by the resulting Revolving Loan or Swingline Loan. Each Issuing Lender shall give the respective Account Parties and the Administrative Agent prompt written notice of each Drawing under any Letter of Credit issued by it,
provided that the failure to give any such notice shall in no way affect, impair or diminish the Borrowers obligations hereunder.

(b) The joint and several obligations of the U.S. Borrowers, the joint and several obligations of the Canadian Borrowers and the obligations of the European Borrower, as



-105-



---

the case may be, under this Section 3.05 to reimburse each Issuing Lender with respect to drafts, demands and other presentations for payment
under Letters of Credit issued by it (each, a Drawing) (including, in each case, interest thereon, if any) shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense
to payment which Aleris or any of its Subsidiaries may have or have had against any Lender (including in its capacity as an Issuing Lender or as a L/C Participant), including, without limitation, any defense based upon the failure of any drawing
under a Letter of Credit to conform to the terms of the Letter of Credit or any nonapplication or misapplication by the beneficiary of the proceeds of such Drawing; provided, however, that the Borrowers shall not be obligated to
reimburse any Issuing Lender for any wrongful payment made by such Issuing Lender under a Letter of Credit issued by it as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Issuing Lender (as
determined by a court of competent jurisdiction in a final and non-appealable decision).

3.06 Increased Costs. (a) If at any
time after the Restatement Effective Date, the introduction of or any change in any applicable law, rule, regulation, order, guideline or request or in the interpretation or administration thereof by the NAIC or any Governmental Authority charged
with the interpretation or administration thereof, or compliance by any Issuing Lender or any L/C Participant with any request or directive by the NAIC or by any such Governmental Authority (whether or not having the force of law), shall either
(i) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against Letters of Credit issued by any Issuing Lender or participated in by any L/C Participant, or (ii) impose on any Issuing Lender or
any L/C Participant any other conditions relating, directly or indirectly, to this Agreement or any Letter of Credit; and the result of any of the foregoing is to increase the cost to any Issuing Lender or any L/C Participant of issuing, maintaining
or participating in any Letter of Credit, or reduce the amount of any sum received or receivable by any Issuing Lender or any L/C Participant hereunder or reduce the rate of return on its capital with respect to the Letters of Credit (except for
changes in the rate of tax on, or determined by reference to, the net income or net profits (or any franchise or similar tax imposed in lieu of a net income or net profits tax of such Issuing Lender or such L/C Participant or, in the
case of an Issuing Lender or L/C Participant that is a flow-through entity for tax purposes, a member or a partner of such Issuing Lender or L/C Participant, pursuant to the laws of the country or national jurisdiction (or any political subdivision
thereof) in which it is organized or in which its principal office or applicable lending office is located), then, upon the delivery of the certificate referred to below to the Account Parties by any Issuing Lender or any L/C Participant (a copy of
which certificate shall be sent by such Issuing Lender or such L/C Participant to the Administrative Agent), such Account Party agrees to pay to such Issuing Lender or such L/C Participant such additional amount or amounts as will compensate such
Issuing Lender or such L/C Participant for such increased cost or reduction in the amount receivable or reduction on the rate of return on its capital. Any Issuing Lender or any L/C Participant, upon determining in good faith that any additional
amounts will be payable pursuant to this Section 3.06, will give prompt written notice thereof to the respective Account Party, which notice shall include a certificate submitted to such Account Party by such Issuing Lender or such L/C
Participant (a copy of which certificate shall be sent by such Issuing Lender or such L/C Participant to the Administrative Agent), setting forth in reasonable detail the basis for and the calculation of such additional amount or amounts necessary
to compensate such Issuing Lender or such L/C Participant. The certificate required to

twelve-month period, the full $500 shall be payable on the date of issuance of such standby Letter of Credit and on each such anniversary thereof and (y) in respect of trade Letters of Credit, in an amount to be agreed with the respective
Issuing Lender. Except as otherwise provided in the proviso to the immediately preceding sentence, accrued Facing Fees shall be due and payable quarterly in arrears on each Quarterly Payment Date and upon the first day on or after the termination of
the Total Commitment, upon which no Letters of Credit remain outstanding.

(d) Each Borrower agrees to pay to each Issuing Lender, for its

Commitment and/or the Total Canadian Commitment, as elected by Aleris. Each reduction to (x) the Total U.S./European Commitment pursuant to this Section 4.02(a) shall apply to proportionately and permanently reduce the U.S./European
Commitment of each U.S./European Lender (based on its relevant U.S./European Percentage) and (y) the Total Canadian Commitment pursuant to this Section 4.02(a) shall apply to proportionately and permanently reduce the Canadian
Commitment of each Canadian Lender (based on its relevant Canadian Percentage).

---

Lender or each directly affected Lender or (ii) that any Lender becomes a Defaulting Lender, Aleris may, subject to its compliance with the requirements
of Section 13.12(d) (in the case of a non-consenting Lender, but not a Defaulting Lender), upon five Business Days prior written notice to the Administrative Agent at the Notice Office (which notice the Administrative Agent shall
promptly transmit to each of the Lenders) terminate all of the Commitments of such Lender (other than any such Commitment which is being maintained by such Lender (and not being terminated by Aleris) as provided in Section 13.12(d), so
long as (x) all Loans (other than any such Loans that are being maintained by such Lender (and not being repaid by Aleris) as provided in Section 13.12(d)), together with accrued and unpaid interest, Fees and all other amounts,
owing to such Lender are repaid concurrently with the effectiveness of such termination pursuant to Section 5.01(b) (at which time Schedule I-A shall be deemed modified to reflect such changed amounts) and (y) such
Lenders L/C Participation Percentage of all outstanding Letters of Credit under any relevant Tranche is cash collateralized by the respective Account Parties in a manner reasonably satisfactory to the Administrative Agent and the respective
Issuing Lenders. After giving effect to the termination of the Commitments of any Lender pursuant to this Section 4.02(b), such Lender shall no longer constitute a Lender for purposes of this Agreement, except with respect to
indemnifications under this Agreement (including, without limitation, Sections 2.10, 2.11, 3.06, 5.04, 12.06 and 13.01), which shall survive as to such repaid Lender. In cases where any Commitment of any
Lender is terminated pursuant to this Section 4.02(b), except in cases where such Commitment is replaced in full, after giving effect to the termination of any such Commitment of a given Lender pursuant to this
Section 4.02(b), there shall occur automatic adjustments (as determined by the Administrative Agent) in the U.S./European Percentages and Canadian Percentages (and as a result thereof in the related L/C Participation Percentages) of the
remaining Lenders.

(c) Each reduction to, or termination of, the Total
U.S./European Commitment and the Total Canadian Commitment pursuant to this Section 4.03 as provided above (or pursuant to Section 4.02(a)) shall be applied to proportionately reduce or terminate, as the case may be, the

case of Base Rate Loans and (y) prior to 12:00 noon (New York time) at the Notice Office (1) at least one Business Day before the date of such
prepayment of its intent to prepay Canadian Prime Rate Loans (other than Swingline Loans), (2) on the date of such prepayment in the case of Swingline Loans and (3) at least three Business Days before the date of such prepayment of its
intent to prepay Euro Rate Loans or Bankers Acceptance Loans, which notice (in each case) shall specify whether U.S. Borrower Revolving Loans, Canadian Revolving Loans, European Borrower Revolving Loans, U.S. Borrower Swingline Loans, European
Borrower Swingline Loans or Canadian Swingline Loans shall be prepaid, the amount of such prepayment and the Types of Loans to be prepaid and, in the case of Euro Rate Loans, the specific Borrowing or Borrowings pursuant to which such Euro Rate
Loans were made, and which notice the Administrative Agent shall, except in the case of Swingline Loans, promptly transmit to each of the Lenders; (ii) (x) each partial prepayment of Revolving Loans (other than Swingline Loans) pursuant to
this Section 5.01(a) shall be in an aggregate principal amount of at least $5,000,000 (or such lesser amount as is acceptable to the Administrative Agent), provided that (x) if any partial prepayment of Eurodollar Loans made
pursuant to any Borrowing shall reduce the outstanding principal amount of Eurodollar Loans made pursuant to such Borrowing to an amount less than the Minimum Borrowing Amount applicable thereto, then such Borrowing may not be continued as a
Borrowing of Eurodollar Loans (and same shall automatically be converted into a Borrowing of Base Rate Loans) and any election of an Interest Period with respect thereto given by such Borrower shall have no force or effect and (y) in the case
of partial prepayments of any Borrowing of Euro Rate Loans, the European Borrower shall use reasonable efforts to allocate such prepayments in a manner so that Borrowings do not remain outstanding in amounts less than the Minimum Borrowing Amount
applicable thereto (and, to the extent such Borrowings would remain outstanding in amounts which are less than the Minimum Borrowing Amount applicable thereto, in the case of Euro Rate Loans, the European Borrower shall repay any Borrowings which
are less than the Minimum Borrowing Amount applicable thereto at the end of the then current Interest Period, unless at such time the European Borrower combines separate Borrowings into one Borrowing, which such Borrowing shall be greater than or
equal to the Minimum Borrowing Amount); (iii) each prepayment pursuant to this Section 5.01(a) in respect of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans, provided that at
such Borrowers election in connection with any prepayment of Revolving Loans pursuant to this Section 5.01(a), such prepayment shall not, so long as no Default or Event of Default then exists, be applied to any Revolving Loan of a
Defaulting Lender; and (iv) prepayments of Bankers Acceptance Loans may not be made prior to the maturity date of the respective underlying Bankers Acceptances or B/A Equivalent Notes, as the case may be.

(b) In the event of (i) a refusal by a Lender to consent to certain proposed changes or waivers with respect to this Agreement which have been
approved by the Required Lenders as (and to the extent) provided in Section 13.12(d) but which require the consent of each Lender or each directly affected Lender or (ii) any Lender becoming a Defaulting Lender, any Borrower may,
upon five Business Days prior written notice to the Administrative Agent at the Notice Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders) repay all Loans, together with accrued and unpaid interest,
Fees, and other amounts owing to such Lender (or owing to such Lender with respect to each Tranche which gives rise to the need to obtain such Lenders individual consent) so long as (1) in the case of the repayment of Revolving Loans of
any Lender of any Tranche pursuant to this Section 5.01(b), (x) the Commitments of the respective Tranche or Tranches of such Lender are terminated concurrently



-110-

with such repayment pursuant to Section 4.02(b) (at which time Schedule I-A shall be deemed modified to reflect the changed Commitments)
and (y) such Lenders L/C Participation Percentage of all outstanding Letters of Credit of the respective Tranche or Tranches is cash collateralized by such Borrower in a manner reasonably satisfactory to the Administrative Agent and the
Issuing Lenders and (2) in the case of any non-consenting Lender, but not a Defaulting Lender, (x) the consents, if any, required under Section 13.12(d) in connection with the repayment pursuant to this
Section 5.01(b) have been obtained and (y) the repayment of such Lenders Loans is otherwise made in accordance with, and subject to the requirements of, said Section 13.12(d) to the extent applicable.

5.02 Mandatory Repayments. (a) (i) On any day on which any one or more of the following conditions shall exist, the Borrowers shall

Acceptance Loans pursuant to clause (iii) below in such amount as may be required to cause such conditions to cease to exist on such day:

(t) the Aggregate U.S. Borrower Exposure exceeds 100% (or, during an Agent Advance Period, 105%) of the U.S. Borrowing Base at such time less the Aggregate Non-U.S. Borrowing Base Usage at such time;

(u) the Aggregate U.S./European Exposure exceeds 100% (or, during an Agent Advance Period, 105%) of the Combined U.S./European Borrowing Base at such
time less the Canadian U.S. Borrowing Base Usage at such time;

(v) the sum of the Aggregate U.S. Borrower Exposure and the
Aggregate Canadian Exposure exceeds 100% (or, during an Agent Advance Period, 105%) of the Combined U.S./Canadian Borrowing Base at such time less the European U.S. Borrowing Base Usage at such time;

(w) the Aggregate Exposure at such time exceeds 100% (or, during an Agent Advance Period, 105%) of the Total Borrowing Base at such time;

For purposes of this Section 5.02(a)(i) the relevant Borrowing Bases will be based upon the Borrowing Base Certificate most recently
delivered.

(ii) If any condition set forth in sub-clauses (x), (y) or (z) of Section 5.02(a)(i)
exists solely as a result of currency fluctuations of Non-Dollar Denominated Loans, then the repayments or cash collateralizations required pursuant to Section 5.02(a)(i) shall



-111-



---

only be required if the relevant excess amount (for this purpose, using the Dollar Equivalent thereof) exceeds 105% of the relevant permitted maximum amount
of the relevant Commitment as then in effect as provided in Section 5.02(a)(i) for more than three consecutive Business Days (at which time the excess of 100% shall be required to be eliminated).

long as no Event of Default then exists, an amount equal to the Net Sale Proceeds therefrom shall not be required to be so applied on such date to the extent that Aleris has given written notice to the Administrative Agent within such ten Business
Day period stating that such Net Sale Proceeds shall be used to purchase assets used, or to be used, in the businesses permitted pursuant to Section 10.10 within 15 months following the receipt thereof (or, if within 15 months following
receipt thereof, Aleris or any of its Subsidiaries enters into a legally binding commitment to reinvest such Net Sale Proceeds, within 180 days following the expiration date of such 15 month period), and (ii) if all or any portion of such Net
Sale Proceeds not required to be so applied as provided above in this Section 5.02(c) are not so reinvested within such time period (or such earlier date, if any, as Aleris or the relevant Subsidiary determines not to reinvest the Net

within such ten Business Day period stating that such Net Insurance Proceeds shall be used to replace or restore properties or assets in respect of which such Net Insurance Proceeds were paid within 15 months following the date of the receipt of
such Net Insurance Proceeds (or, if within 15 months following the receipt thereof, Aleris or any of its Subsidiaries enters into a legally binding commitment to reinvest such Net Insurance Proceeds, within 180 days of the date following the
expiration date of such 15-month period), and provided, further, that if all or any portion of such Net Insurance Proceeds not required to be so applied pursuant to the preceding proviso are not so used within such time period (or such
earlier date, if any, as Aleris or the relevant Subsidiary determines not to reinvest the Net Insurance Proceeds relating to such Recovery Event as set forth above), an amount equal to such remaining portion shall be applied on the last day of such
period (or such earlier date, as the case may be) as provided above in this Section 5.02(d) without regard to the preceding proviso.

(g) Notwithstanding anything to the contrary contained in Sections 5.02(b), (c) and (d), so long as any Term Loans are
outstanding, then to the extent that any cash proceeds referred to in any such clause of this Section 5.02 are used to repay outstanding Term Loans, the repayments otherwise required pursuant to such clauses of this
Section 5.02 shall not be required to the extent of the respective net cash proceeds so applied, provided that if at the time of any required repayment pursuant to Sections 5.02(b), (c) or (d), the sum (the
Sum) of (1) Excess Availability and (2) the amount of the cash and Cash Equivalents of Aleris and its Subsidiaries (other than cash and Cash Equivalents which are Restricted, on deposit in an Exempted Deposit Account or
to be applied to repay Term Loans) is less than $100,000,000, the amounts required to be applied pursuant to such Sections (before giving effect to this clause (g)) shall be applied first to the repayment of the Loans to the extent required to cause
the Sum to equal $100,000,000 and thereafter to the Term Loans to the extent required under the Term Loan Agreement.

(i) Notwithstanding anything in this Section 5.02 to the contrary, it is understood and
agreed that none of Sections 5.02(b) through (d), inclusive, shall require that amounts received by any Foreign Subsidiary or Foreign Subsidiaries or a Domestic Subsidiary which is a Subsidiary of a Foreign Subsidiary be used to
repay ABL Obligations owed by any U.S. Credit Parties.

(j) Notwithstanding the foregoing provisions of this Section 5.02
(other than clause (a) of this Section 5.02, which clause shall not have the benefits of this sentence), if at any time the mandatory repayment of Loans pursuant to this Section 5.02 would result in the Borrowers
incurring breakage costs under Section 2.11 as a result of Euro Rate Loans being repaid other than on the last day of an Interest Period applicable hereto (any such Euro Rate Loans, Affected Loans), Aleris may elect,
by written notice to the Administrative Agent, to have the provisions of the following sentence be applicable so long as no Default or Event of Default then exists. At the time any Affected Loans are otherwise required to be prepaid, Aleris may
elect to deposit 100% (or such lesser percentage elected by Aleris as not being repaid) of the principal amounts that otherwise would have been paid in respect of the Affected Loans with the Administrative Agent to be held as security for the
obligations of the respective Borrowers hereunder pursuant to a cash collateral agreement to be entered into in form and substance reasonably satisfactory to the Administrative Agent and shall provide for investments of such deposits in Cash
Equivalents, with such cash collateral to be released upon the request of Aleris from such cash collateral account (and applied to repay the principal amount of such Euro Rate Loans) upon each occurrence thereafter of the last day of an Interest
Period applicable to such Euro Rate Loans (or such earlier date or dates as shall be requested by Aleris, with the amount to be so released and applied on the last day of each Interest Period to be the amount of such Euro Rate Loans to which such
Interest Period applies (or, if less, the amount remaining in such cash collateral account); provided that (i) interest in respect of such Affected Loans shall continue to accrue thereon at the rate provided hereunder until such Affected
Loans have been repaid in full and (ii) at any time while an Event of Default has occurred and is continuing or upon written notice from the Required Lenders, the Required Lenders may direct the Administrative Agent (in which case the
Administrative Agent shall, and is hereby authorized by the Borrowers to, follow said directions) to apply any or all proceeds then on deposit in such collateral account to the payment of such Affected Loans. All risk of loss in respect of
investments made as contemplated in this clause (j) shall be on the Borrowers. Under no circumstances shall the Administrative Agent be liable or accountable to the Borrowers or any other Person for any decrease in the value of the cash
collateral account or for any loss resulting from the sale of any investment so made.

5.03 Payments and Computations; Maintenance of
Accounts; Statement of Accounts. (a) Except as otherwise specifically provided herein, all payments under this Agreement and under any Note shall be made to the Administrative Agent for the account of the Lender or Lenders entitled thereto

Currency Denominated Loans (or Commitments relating thereto) at any time prior to the occurrence of a Conversion Event. Nothing in the succeeding clauses of this Section 5.03 shall affect or alter the Borrowers obligations to the
relevant Administrative Agent, the Collateral Agent, the Issuing Lenders and the Lenders with respect to all payments otherwise required to be made by the Borrowers in accordance with the terms of this Agreement and the other Credit Documents.

of each of the Borrowers (collectively, the Credit Account) in which each Borrower will be charged with all loans and advances made by the Lenders to such Borrower for such Borrowers account, including the Loans, the Letter
of Credit Outstandings, and the Fees, Expenses and any other ABL Obligations relating thereto. Each Borrower will be credited, in accordance with this Section 5.03, with all amounts received by the Lenders from such Borrower or from
others for its account, including, as set forth above, all amounts received by the Administrative Agent and applied to the ABL Obligations. In no event shall prior recourse to any Accounts or other Collateral be a prerequisite to the Administrative
Agents right to demand payment of any Obligation upon its maturity. Further, the Administrative Agent shall have no obligation whatsoever to perform in any respect any of Aleris or any of its Subsidiaries contracts or obligations
relating to the Accounts.

(f) After the end of each month, the Administrative Agent shall send Aleris and each Lender a statement
accounting for the charges, loans, advances and other transactions occurring among and between the Administrative Agent, the Lenders, the Issuing Lenders and each Borrower during that month. The monthly statements shall, absent manifest error, be
final, conclusive and binding on each Borrower and the Lenders.

5.04 Net Payments. (a) All payments made by or on behalf of
any Credit Party under any Credit Document (including, in the case of each Borrower, in its capacity as a guarantor pursuant to Section 14) in each case will be made without setoff, counterclaim or other defense. Except as provided in
Section 5.04(b), all such payments will be made free and clear of, and without deduction or withholding for, any Taxes. If any Taxes are levied or imposed with respect to such payment, the relevant Borrower (and any Credit Party making
the respective payment or which has guaranteed the obligations of the relevant Borrower) agrees to pay the full amount of such Taxes to the appropriate taxing authority, and shall pay to the applicable Section 5.04 Indemnitee such
additional amounts as may be necessary so that every payment of all



-119-



---

amounts due under this Agreement or under any other Credit Document, after withholding or deduction for or on account of any Taxes (including, for the
avoidance of doubt, withholding and deductions applicable to additional amounts payable under this Section 5.04), will not be less than the amount provided for herein or in such other Credit Document. The respective Borrowers will
furnish to the Administrative Agent within 45 days after the date the payment of any Taxes is due pursuant to applicable law certified copies of tax receipts or other evidence reasonably satisfactory to the Administrative Agent evidencing such
payment by such Borrowers or the respective Credit Party. The U.S. Borrowers (jointly and severally), the Canadian Borrowers (jointly and severally) and the European Borrower (and any Credit Party making the respective payment or which has
guaranteed the obligations of the respective Borrower), as applicable, agree to indemnify and hold harmless each Section 5.04 Indemnitee and reimburse such Section 5.04 Indemnitee upon its written request (which shall set forth the
basis and calculation of such amount) for the amount of any Taxes so levied or imposed and paid by such Section 5.04 Indemnitee. Notwithstanding anything to the contrary in this Section 5.04(a), (i) any payments required to be
made pursuant to this Section 5.04(a) to an Indirect Section 5.04 Indemnitee shall be made to the Related Pass Through Entity and (ii) any request for reimbursement pursuant to this Section 5.04(a) that is to
be made by an Indirect Section 5.04 Indemnitee shall be made by the Related Pass Through Entity.

each Lender that is a Lender to the U.S. Borrowers and is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) agrees to deliver to Aleris and the Administrative Agent on or prior to the Restatement Effective
Date or, in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to Section 2.13 or 13.04(b) (unless the respective Lender was already a Lender hereunder immediately prior to such
assignment or transfer and is in compliance with the provisions of this paragraph), on the date of such assignment or transfer to such Lender or, in the case of a successor Issuing Lender, the date such Issuing Lender becomes an Issuing Lender,
(i) two accurate and complete original signed copies of U.S. Internal Revenue Service Form W-8ECI or Form W-8BEN (with respect to a complete exemption from withholding under an income tax treaty) (or successor forms) certifying to such
Lenders entitlement as of such date to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note, or (ii) if the Lender is not a bank within the meaning
of Section 881(c)(3)(A) of the Code and cannot deliver forms described in clause (i) above, (x) a certificate substantially in the form of Exhibit D (any such certificate, a Section 5.04(b)(ii)
Certificate) and (y) two accurate and complete original signed copies of U.S. Internal Revenue Service Form W-8BEN (with respect to the portfolio interest exemption) (or successor form) certifying to such Lenders entitlement as
of such date to a complete exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any Note or (iii) in the case of the Administrative Agent and each such Lender, if a Lender
or the Administrative Agent is a foreign intermediary or flow-through entity for U.S. federal income tax purposes, two accurate and complete signed copies of Internal Revenue Service Form W-8IMY (and all necessary attachments) establishing a
complete exemption from United States withholding tax with respect to payments made to the Administrative Agent or the applicable Lender, as the case may be, under this Agreement and under any Note. In addition, the Administrative Agent and each
Lender to the U.S. Borrowers agrees that from time to time after the Restatement Effective Date, when a lapse in time or change in circumstances or law renders the previous certification obsolete, invalid or inaccurate



-120-



---

in any material respect, the Administrative Agent or such Lender will deliver to Aleris and the Administrative Agent two new accurate and complete original
signed copies of U.S. Internal Revenue Service Form W-8ECI, Form W-8BEN (with respect to the benefits of any income tax treaty), or Form W-8BEN (with respect to the portfolio interest exemption) and a Section 5.04(b)(ii) Certificate, or
Form W-8IMY (with respect to foreign intermediary or flow through entity), as the case may be, and such other forms and necessary attachments as may be required in order to confirm or establish the entitlement of such Person to a continued exemption
from United States withholding tax with respect to payments under this Agreement and any Note, or the Administrative Agent and/or such Lender shall immediately notify Aleris and the Administrative Agent of its inability to deliver any such form or
Section 5.04(b)(ii) Certificate, in which case the Administrative Agent and/or such Lender shall not be required to deliver any such new form or Section 5.04(b)(ii) Certificate pursuant to this Section 5.04(b).
Notwithstanding the foregoing, with respect to payments made by any Credit Party under any Credit Document to or for the benefit of a Participant, such Participant shall be required to provide forms and/or certificates pursuant to the preceding
sentences of this Section 5.04(b) only to the extent that such Participant is legally entitled to do so. The Administrative Agent and each Lender that is a Lender to the U.S. Borrowers and is a United States person (as such term is
defined in Section 7701(a)(30) of the Code) for U.S. federal income tax purposes (other than an Administrative Agent or Lender that may be treated as an exempt recipient based on the indicators described in U.S. Treasury Regulation
Section 1.6049-4(c)(1)(ii) except to the extent required by Treasury Regulation Section 1.1441-1(d)(4) (and any successor provision)) agrees to deliver (with respect to itself only) to Aleris and the Administrative Agent, on or prior to
the Restatement Effective Date or, in the case of such an Administrative Agent appointed after the Restatement Effective Date pursuant to Section 12.09 or a Lender that is an assignee or transferee of an interest under this Agreement
pursuant to Section 2.13 or 13.04(b) (unless the respective Lender was already a Lender to the U.S. Borrowers hereunder immediately prior to such assignment or transfer and is in compliance with the provisions of this paragraph),
on the date of such assignment or transfer to such Lender, two accurate and complete original signed copies of U.S. Internal Revenue Service Form W-9 (or successor forms) certifying to such Persons entitlement as of such date to a complete
exemption from United States backup withholding tax with respect to payments to be made under this Agreement and under any other Credit Document. Notwithstanding anything to the contrary contained in Section 5.04(a), but subject to
Section 13.04(b) and the second succeeding sentence, (x) the U.S. Borrowers shall be entitled, to the extent they are required to do so by law, to deduct or withhold Taxes imposed by the United States (or any political subdivision
or taxing authority thereof or therein) from interest, Fees or other amounts payable hereunder for the account of the Administrative Agent and/or any Lender, as the case may be, to the extent that the Administrative Agent and/or such Lender, as the
case may be, has not provided to such Borrower U.S. Internal Revenue Service Forms that establish a complete exemption from deduction or withholding and (y) no Borrower shall be obligated pursuant to Section 5.04(a) to gross-up
payments to be made to the Administrative Agent and/or a Lender (other than a Participant following the occurrence of a Conversion Event), as the case may be, in respect of withholdings, income or similar taxes imposed by the United States federal
government if (I) the Administrative Agent and/or such Lender, as the case may be, has not provided to such Borrower the U.S. Internal Revenue Service Forms required to be provided to such Borrower pursuant to this Section 5.04(b)
or (II) in the case of a payment, other than interest, to the Administrative Agent and/or a Lender (other than a



-121-



---

Participant following the occurrence of a Conversion Event), as the case may be, described in clause (ii) above, to the extent that such forms do not
establish a complete exemption from withholding of such taxes. Except when a Significant Event of Default has occurred and is continuing or following a Conversion Event, and notwithstanding anything to the contrary in Section 5.04(a),
but subject to Section 13.04(b) and the immediately succeeding sentence, (x) the Canadian Borrowers shall be entitled, to the extent they are required to do so by law, to deduct or withhold income or similar Taxes imposed by Canada
(or any political subdivision or taxing authority thereof or therein) from interest, Fees or other amounts payable hereunder for the account of the Canadian Administrative Agent, any Canadian Lender and/or any Issuing Lender in respect of a Letter
of Credit issued in favor of a Canadian Borrower, as the case may be, to the extent that the Canadian Administrative Agent and/or such Canadian Lender or Issuing Lender, as the case may be, is not a Canadian Resident or if the Canadian
Administrative Agent or Canadian Lender or Issuing Lender (if not a Canadian Resident) has not provided forms required by Section 2.17(a) that establish a complete exemption from the withholding of such Taxes (or the withholding of such
Taxes at a reduced rate) and (y) no Canadian Borrower shall be obligated pursuant to Section 5.04(a) to gross-up payments to be made to the Canadian Administrative Agent and/or a Canadian Lender or Issuing Lender, as the case may
be, in respect of withholdings, income or similar Taxes imposed by Canada (or any political subdivision or taxing authority thereof or therein) if (I) the Canadian Administrative Agent, such Canadian Lender and/or such Issuing Lender in respect
of a letter of credit issued in favor of a Canadian Borrower is not a Canadian Resident or (II) the Canadian Administrative Agent or such Canadian Lender or such Issuing Lender (if not a Canadian Resident) has not provided forms required by
Section 2.17(a) that establish a complete exemption from the withholding of such Taxes (or the withholding of such Taxes at a reduced rate). Notwithstanding anything to the contrary contained in the two preceding sentences or elsewhere
in this Section 5.04 and except as set forth in Section 13.04(b), the respective U.S. Borrowers (jointly and severally), Canadian Borrowers (jointly and severally as to amounts payable by any Canadian Borrower) and the
European Borrower (and any Credit Party making the respective payment or which has guaranteed the obligations of the respective Borrower) agree to pay any additional amounts and to indemnify each Lender in the manner set forth in
Section 5.04(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect of any amounts deducted or withheld by it as described in the two immediately preceding sentences as a result of any
changes after the Restatement Effective Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of income or similar taxes; provided,
however, that (x) this sentence shall not apply to the portion of such amounts required to be deducted or withheld by such Borrower or Borrowers to the extent such Borrower or Borrowers would have been required to pay additional amounts
pursuant to Section 5.04(a) irrespective of such change in such applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof and (y) this sentence shall not be read to permit the
Administrative Agent and/or a Lender to a U.S. Borrower to refuse to deliver any Form W-8ECI, Form W-8BEN, Form W-8IMY, orSection 5.04(b)(ii) Certificate, as the case may be, except where, as a result of such change in law, treaty,
governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of income or similar taxes, the Administrative Agent and/or such Lender is unable to deliver such form or certificate as
described above.



-122-



---

(c) Each Lender agrees to use reasonable efforts (consistent with legal and regulatory restrictions and
subject to overall policy considerations of such Lender) to file any certificate or document or to furnish to the relevant non-U.S. Borrower any information, in each case, as reasonably requested by such non-U.S. Borrower that may be necessary to
establish any available exemption from, or reduction in the amount of, any Taxes; provided, however, that nothing in this Section 5.04(c) shall require a Lender to disclose any confidential information (including, without
limitation, its tax returns or its calculations).

(d) If a Borrower pays any additional amount under this Section 5.04 to a
Section 5.04 Indemnitee, and such Section 5.04 Indemnitee determines in its reasonable sole discretion that it has actually received or realized in connection therewith any refund or any reduction of, or credit against
(including, for the avoidance of doubt, any foreign tax credit), its tax liabilities in or with respect to the taxable year in which the additional amount is paid (a Tax Benefit), such Section 5.04 Indemnitee shall pay
to such Borrower an amount (not to exceed the additional amounts paid by such Borrower under this Section 5.04 with respect to Taxes giving rise to such Tax Benefit) that the Section 5.04 Indemnitee shall, in its reasonable
sole discretion, determine is equal to the net benefit, after tax, which was obtained by such Section 5.04 Indemnitee in such year as a consequence of such Tax Benefit; provided, however, that (i) any
Section 5.04 Indemnitee may determine, in its sole discretion consistent with the policies of such Section 5.04 Indemnitee, whether to seek a Tax Benefit; (ii) any taxes that are imposed on a Section 5.04
Indemnitee as a result of a disallowance or reduction (including through the expiration of any tax credit carryover or carryback of such Section 5.04 Indemnitee that otherwise would not have expired) of any Tax Benefit with respect to
which such Section 5.04 Indemnitee has made a payment to such Borrower pursuant to this Section 5.04(d) shall be treated as a Tax for which such Borrower is obligated to indemnify such Section 5.04 Indemnitee
pursuant to this Section 5.04 without any exclusions or defenses; (iii) nothing in this Section 5.04(d) shall require any Section 5.04 Indemnitee to disclose any confidential information to any Borrower
(including, without limitation, its tax returns or its calculations); and (iv) no Section 5.04 Indemnitee shall be required to pay any amounts pursuant to this Section 5.04(d) at any time that a Default or an Event of
Default exists.

(e) If a Borrower determines in good faith that a reasonable basis exists for contesting any Taxes for which additional
amounts have been paid under this Section 5.04 to a Section 5.04 Indemnitee, such Section 5.04 Indemnitee shall cooperate with the Borrower in challenging such Taxes, at the Borrowers expense, if so requested by the Borrower in
writing.

5.05 Minimum Interest Rates and Payments. (a) The various rates of interests provided for in this Agreement
(including, without limitation, under Section 2.08) are minimum interest rates.

(b) When entering into this Agreement, each
party hereto has assumed that the payments required under this Agreement are not and will not become subject to Swiss Withholding Tax. Notwithstanding that the parties hereto do not anticipate that any payment will be subject to Swiss Withholding
Tax, they agree that, in the event that Swiss Withholding Tax should be imposed on interest or other payments (the Relevant Amount) by a Swiss Obligor, any payment of interest due by such Swiss Obligor shall, subject to the
provisions of this Agreement, be increased to an amount which (after making any deduction of the Swiss



-123-



---

Withholding Tax) results in a payment to each Lender entitled to such payment of an amount equal to the payment which would have been due had no deduction of
Swiss Withholding Tax been required. For this purpose, the Swiss Withholding Tax shall be calculated on the full grossed-up amount.

(c)
The European Borrower shall not be required to make an increased payment to any specific Lender (but without prejudice to the rights of all other Lenders hereunder) under paragraph (b) above or under Section 5.04 in connection with
a Swiss Withholding Tax if the European Borrower has breached the Ten Non-Bank Regulations and/or Twenty Non-Bank Regulations as a direct result of (i) the incorrectness of the representation made by such Lender on the Restatement Effective
Date pursuant to the first sentence of Section 2.19 (if Schedule I-C specified that such Lender was a Swiss Qualifying Lender) or (ii) such Lender, as assignee or participant, breaching the requirements and limitations for
transfers, assignments or sub-participations (including Restricted Sub-Participations) pursuant to Section 13.04.

(d) For the
avoidance of doubt, the European Borrower shall be required to make an increased payment to a specific Lender under paragraph (b) above in connection with the imposition of a Swiss Withholding Tax if the European Borrower has breached the Ten
Non-Bank Regulations and/or the Twenty Non-Bank Regulations as a result of its failure to comply with the provisions of Section 10.10 or, if after a Significant Event of Default or Conversion Event, lack of compliance with the Ten
Non-Bank Regulations and/or the Twenty Non-Bank Regulations as a result of assignments or participation effected in accordance herewith.

(e) If requested by the Administrative Agent, a Swiss Obligor shall provide to the Administrative Agent those documents which are required by law and applicable double taxation treaties to be provided by the payer of such tax for each
relevant Lender to prepare a claim for refund of Swiss Withholding Tax. In the event Swiss Withholding Tax is refunded to the Lender by the Swiss Federal Tax Administration, the relevant Lender shall forward, after deduction of costs, such amount to
the Swiss Obligor; provided, however, that (i) the relevant Swiss Obligor has fully complied with its obligations under this Section 5.05; (ii) the relevant Lender may determine, in its sole discretion, consistent
with the policies of such Lender, the amount of the refund attributable to Swiss Withholding Tax paid by the relevant Swiss Obligor; (iii) nothing in Section 5.05 shall require the Lender to disclose any confidential information to
the Swiss Obligor (including, without limitation, its tax returns); and (iv) no Lender shall be required to pay any amounts pursuant to this Section 5.05(e) at any time during which a Default or Event of Default exists.

SECTION 6. Conditions Precedent to Credit Events on the Restatement Effective Date. The obligation of each Lender to make Loans (including by
way of the conversion of the Existing Loans on the Restatement Effective Date as contemplated in Sections 2.01(a), (b) and (c)), and the obligation of each Issuing Lender to issue Letters of Credit (including any
Existing Letters of Credit deemed issued on the Restatement Effective Date as contemplated in Section 3.01(c)), in each case on the Restatement Effective Date, are subject at the time of the making or converting of such Loans or the
issuance or deemed issuance of such Letters of Credit to the satisfaction of the following conditions (unless waived in accordance with Section 13.12):

such Mortgage will create, as security for the obligations purported to be secured thereby, a valid and enforceable perfected security interest in and charge and mortgage lien on the respective Mortgaged Property in favor of the Collateral Agent (or

time that Aleris or any of its Subsidiaries are not in compliance with Section 9.10(a) or (iii) in the event that the Administrative Agent or the Lenders have exercised any of the remedies pursuant to the last paragraph of

Security; Further Assurances; etc. (a) Subject to applicable law and the provisions of this Section 9.11, Aleris shall, and shall cause each of the Credit Parties to, cause (i) each of its Wholly-Owned Subsidiaries (other than

this Agreement in accordance with the terms of this Agreement and (ii) any such Subsidiary that was an Immaterial Subsidiary but, as of the end of the most recently ended Fiscal Quarter has ceased to qualify as an Immaterial Subsidiary, to
become a Credit Party as promptly thereafter as reasonably practicable by executing a Joinder Agreement in substantially the form set forth as Exhibit R hereto (the Joinder Agreement). Upon execution and delivery thereof,
each party to a Joinder Agreement (i) shall automatically become a Guarantor (or, to the extent requested by the Adminitrative Agent or Aleris, a Borrower) hereunder and thereupon shall have all of the rights, benefits, duties, and obligations
in such capacity under the Credit Documents; provided however, that only entities which are organized under the laws of the United States or any state or territory thereof or the laws of Canada or any province or territory thereof
shall be permitted to become a Borrower hereunder and (ii) will simultaneously therewith or as soon as practicable thereafter grant Liens to the Administrative Agent, for the benefit of the Administrative Agent and the Lenders and each other
Secured Creditor at such time party to or benefiting from the Intercreditor Agreement or the Security Documents, on any property of such Credit Party which constitutes Collateral, on such terms as may be required pursuant to the terms of the

-151-



---

as a partnership for federal income tax purposes that holds Equity Interests of a Foreign Subsidiary whose Equity Interests are pledged pursuant to clause
(ii) below or any Domestic Subsidiary which is a Subsidiary of any Foreign Subsidiary, (ii) 65% (or such lesser percentage held by Aleris or such other Credit Party) of the issued and outstanding Equity Interests entitled to vote (within
the meaning of Treas. Reg. Section 1.956-2(c)(2)) and 100% (or such lesser percentage held by Aleris or such other Credit Party) of the issued and outstanding Equity Interests not entitled to vote (within the meaning of Treas. Reg.
Section 1.956-2(c)(2)) in each Foreign Subsidiary directly owned by Aleris or any of the Credit Parties which is a Domestic Subsidiary and (iii) 100% (or such lesser percentage held by Aleris or such other Credit Party) of the issued and
outstanding Equity Interests of each of its Foreign Subsidiaries held by a European Credit Party, to be subject at all times to a first priority perfected Lien in favor of the Administrative Agent pursuant to the terms and conditions of the Credit
Documents or other security documents as the Administrative Agent shall reasonably request; provided, however, this paragraph (b) shall not require Aleris or any of its Subsidiaries to grant a security interest in (i) any
Equity Interests of a Subsidiary to the extent a pledge of such Equity Interests in favor of the Administrative Agent or to secure any debt securities of Aleris or any of its Subsidiaries that would be entitled to such a security interest would
require separate financial statements of a Subsidiary to be filed with the Securities and Exchange Commission (or any other government agency) under Rule 3 10 or Rule 3 16 of Regulation S-X under the Securities Act (or any successor thereto) or any
other law, rule or regulation, (ii) the Equity Interests of any Unrestricted Subsidiary or (iii) any interests in joint ventures and non-Wholly Owned Subsidiaries to the extent the same cannot be pledged without the consent of one or more
third parties.

(c) Without limiting the foregoing, Aleris will, and will cause each of the Credit Parties to, execute and deliver, or
cause to be executed and delivered, to the Administrative Agent such documents, agreements and instruments, and will take or cause to be taken such further actions (including the filing and recording of financing statements, fixture filings,
mortgages, deeds of trust and other documents and such other actions or deliveries of the type required by Section 6, including opinions of counsel, as applicable), which may be required by law or which the Administrative Agent may, from
time to time, reasonably request to carry out the terms and conditions of this Agreement and the other Credit Documents and to ensure perfection and priority of the Liens created or intended to be created by the Security Documents, all at the
expense of the Credit Parties; provided that, in no event will Aleris or any of its Subsidiaries be required to take any action, other than using its commercially reasonable efforts, to obtain consents from third parties with respect to its
compliance with this Section 9.11(c).

(d) Subject to the limitations set forth or referred to in this
Section 9.11, if any material assets (including any real property or improvements thereto or any interest therein) are acquired by Aleris or any Credit Party after the Restatement Effective Date (other than assets constituting Collateral
under the Security Documents that become subject to the Lien in favor of the Administrative Agent upon acquisition thereof), Aleris will notify the Administrative Agent and the Lenders thereof, and, if requested by the Administrative Agent or the
Required Lenders, Aleris will cause such assets to be subjected to a Lien securing the ABL Obligations of such Credit Party and will take, and cause the Credit Parties to take, such actions as shall be necessary or reasonably requested by the
Administrative Agent to grant and perfect such Liens, including actions described in paragraph (c) of this Section 9.11, all at the expense of the Credit Parties.



-152-

(e) If, at any time and from time to time after the Restatement Effective Date, Subsidiaries that are not
Credit Parties because they are Immaterial Subsidiaries comprise in the aggregate more than 5% of Total Assets as of the end of the most recently ended Fiscal Quarter or more than 5% of Consolidated EBITDA of Aleris and the Restricted Subsidiaries
for the most recently ended Test Period, then Aleris shall, not later than 45 days after the date by which financial statements for such Fiscal Quarter are required to be delivered pursuant to this Agreement, cause one or more such Subsidiaries to
become additional Credit Parties (notwithstanding that such Subsidiaries are, individually, Immaterial Subsidiaries) such that the foregoing condition ceases to be true.

(f) Notwithstanding anything to the contrary in this Section 9.11, real property required to be mortgaged under this Section 9.11 shall be limited to real property that is owned in fee by a
Credit Party having a fair market value at the time of the acquisition thereof of $2,500,000 or more (provided that the cost of perfecting such Lien is not unreasonable in relation to the benefits to the Lenders of the security afforded
thereby in the Administrative Agents reasonable judgment after consultation with Aleris).

(g) Notwithstanding anything to the
contrary contained herein, neither Aleris nor any Subsidiary of Aleris shall be required to:

(i) execute and deliver any
Joinder Agreement, Guaranty or any other document or grant a Lien in any Equity Interests or other property held by it if such action (w) is restricted or prohibited by general statutory limitations, financial assistance, corporate benefit,
fraudulent preference, thin capitalization rules or similar principles, (x) would result in adverse tax consequences, (v) is not within the legal capacity of Aleris or such Subsidiary or would conflict with the fiduciary duties
of its directors or contravene any legal prohibition or result in personal or criminal liability on the part of any officer or (z) for reasons of cost, legal limitations or other matters is unreasonably burdensome in relation to the benefits to
the Secured Creditors of Aleris or such Subsidiarys guaranty or security;

(ii) pledge as Collateral any assets
excluded therefrom pursuant to the relevant Security Documents; or

(iii) to the extent it is a Foreign Subsidiary (other
than the Luxco Guarantor) or a Domestic Subsidiary of a Foreign Subsidiary, guarantee the Term Obligations of any U.S. Credit Party.

(h)
If the Administrative Agent, the Collateral Agent or the Required Lenders reasonably determine that they are required by law or regulation to have appraisals prepared in respect of any Real Property of Aleris and its Subsidiaries constituting
Collateral, the Administrative Agent or the Collateral Agent will, at the expense of Aleris, obtain appraisals which satisfy the applicable requirements of the Real Estate Appraisal Reform Amendments of the Financial Institution Reform, Recovery and
Enforcement Act of 1989, as amended, and which shall otherwise be in form and substance reasonably satisfactory to the Administrative Agent.

9.12 Ownership of Subsidiaries; etc. Except as otherwise contemplated by Sections 10.02,
10.05 and 10.11, Aleris will cause each of its Subsidiaries to be a Wholly-Owned Subsidiary. The sale or issuance of the Equity Interests of a Subsidiary of Aleris to a Person other than Aleris or a Subsidiary of Aleris shall
constitute an Investment by Aleris therein at the date of designation in an amount equal to the product of (x) percentage of Aleriss Investment in such Subsidiary (after giving effect to such sales or issuance) and (y) the fair
market value of the net assets of the respective Subsidiary at the time that the Equity Interests in such Subsidiary as sold at issue.

Permitted Acquisition shall consist solely of Qualified Equity Interests of Aleris and no Default or Event of Default shall have occurred and be continuing at the time of the proposed Permitted Acquisition and immediately after giving effect
thereto, (ii) the Payment Conditions are satisfied (both before and after giving effect to the respective Permitted Acquisition) at such time or (iii) subject to the last sentence of this Section 9.13(a), the aggregate consideration
(excluding consideration in form of Qualified Equity Interests, and treating any such consideration as if not paid under this clause (iii) for purposes of determinations pursuant to Sections 10.03(x), 10.05(xvi) and
10.08(i)(y)) for all Permitted Acquisitions made at any time when the Payment Conditions are not satisfied pursuant to this Section 9.13(a) (iii) would not exceed $40,000,000 in the aggregate since the Restatement Effective
Date, less the sum of (1) the aggregate amount of Investments previously made by Aleris or any of its Subsidiaries pursuant to Section 10.05(xvi) since the Restatement Effective Date (determined as the amount originally
advanced, loaned or otherwise invested (without giving effect to any write-downs or write-offs thereof), less any returns on the respective investment not to exceed the original amount invested), (2) the aggregate amount of Dividends previously
paid by Aleris or any of its Subsidiaries pursuant to Section 10.03(x) since the Restatement Effective Date and (3) the aggregate amount of payments, prepayments and redemptions of Indebtedness previously made by Aleris or any of
its Subsidiaries pursuant to Section 10.08(i)(y) since the Restatement Effective Date. If the aggregate consideration for such Permitted Acquisition (determined in accordance with preceding clause (iii)) equals or exceeds $10,000,000
Aleris shall have delivered to the Administrative Agent a certificate executed by one of its Financial Officers certifying compliance with the requirements of preceding clauses (i) through (iii) (to the extent applicable). In the event
that Aleris or a Subsidiary consummates an acquisition, makes an Investment, pays a Dividend or pays, prepays or redeems Indebtedness (each an Action) in reliance on the basket provided under Section 9.13(a)(iii),
Section 10.05(xvi), Section 10.03(x) or Section 10.08(i)(y), as the case may be, and the Payment Conditions are thereafter satisfied, such Action shall be deemed to have been made at a time when the Payment
Conditions are satisfied and shall not be deemed to be a utilization of such basket.

(b) At the time of each Permitted Acquisition
involving the creation or acquisition of a Subsidiary, or the acquisition of any Equity Interests of any Person, the Equity Interests thereof created or acquired in connection with such Permitted Acquisition shall be pledged to the extent required
by Section 9.11.

(c) Aleris will cause each Subsidiary which is formed to effect, or is acquired pursuant to, a Permitted

(ii) immediately after giving effect to such designation, any Investment in such Unrestricted Subsidiary is permitted pursuant to Section 10.05, (iii) none of Aleris, the Canadian Borrowers nor the European Borrower may be
designated as an Unrestricted Subsidiary, and (iv) no Subsidiary may be designated as an Unrestricted Subsidiary if it is a Restricted Subsidiary for the purposes of the New Senior Subordinated Notes, the New Senior Notes or the
Term Loan Agreement. The designation of any Subsidiary as an Unrestricted Subsidiary shall constitute an Investment by Aleris therein at the date of designation in an amount equal to the product of (x) percentage of Aleriss Investment in
such Subsidiary and (y) the net book value of the respective Subsidiary at the time that such Subsidiary is designated an Unrestricted Subsidiary. The designation of any Unrestricted Subsidiary as a Subsidiary shall constitute the incurrence at
the time of designation of any Indebtedness or Liens of such Subsidiary existing at such time.

Aleris hereby designates the ABL Obligations to be Designated Senior Indebtedness under the New Senior Subordinated Note Indenture.

repurchase such property or assets (including sales of accounts receivable with recourse to such Borrower or any of its Subsidiaries), or assign any right to receive income; provided that the provisions of this Section 10.01 shall
not prevent the creation, incurrence, assumption or existence of the following (Liens described below are herein referred to as Permitted Liens):

Credit Documents and any other instruments and agreements referred to herein or therein and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of the Administrative Agent by the
terms hereof and thereof and such other powers as are reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder by or through its officers, directors, agents, employees or affiliates (it being understood and

responsible to any Lender or the holder of any Note for any recitals, statements, information, representations or warranties herein or in any document, certificate or other writing delivered in connection herewith or for the execution,

accordance with the instructions of the Required Lenders.

shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by any Person
that the Administrative Agent believed to be the proper Person, and, with respect to all legal matters pertaining to this Agreement and any other Credit Document and its duties hereunder and thereunder, upon advice of counsel selected by the
Administrative Agent.

Administrative Agents (or such affiliates) gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision).

12.07 The Administrative Agent in its Individual Capacity. With respect to its obligation to make Loans, or issue or participate in Letters of
Credit, under this Agreement, the Administrative Agent shall have the rights and powers specified herein for a Lender and may exercise the same rights and powers as though it were not performing the duties specified herein; and the term
Lender, Required Lenders, holders of Notes or any similar terms shall, unless the context clearly indicates otherwise, include the Administrative Agent in its individual capacity. The Administrative Agent and its
affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, investment banking, trust or other business with, or provide debt financing, equity capital or other services (including financial advisory services) to
any Credit Party or any Affiliate of any Credit Party (or any Person engaged in a similar business with any Credit Party or any Affiliate thereof) as if they were not performing the duties specified herein, and may accept fees and other
consideration from any Credit Party or any Affiliate of any Credit Party for services in connection with this Agreement and otherwise without having to account for the same to the Lenders.

12.08 Holders. The Borrowers and the Administrative Agent shall deem and treat the payee of any Note as the owner thereof for all purposes hereof
unless and until a written notice of the assignment, transfer or endorsement thereof, as the case may be, together with the relevant Assignment and Assumption Agreement shall have been filed with the Administrative Agent or the Canadian
Administrative Agent, as applicable. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or endorsee, as the case may be, of such Note or of any Note or Notes issued in exchange therefor.

Resignation by the Administrative Agent. (a) The Administrative Agent may resign from the performance of all its functions and duties hereunder and/or under the other Credit Documents at any time by giving 20 Business Days prior
written notice to the Lenders and, unless an Event of Default under Section 11.05 then exists, Aleris. Any such resignation by the Administrative Agent hereunder shall also constitute its resignation as an Issuing Lender and Swingline
Lender, in which case the Administrative Agent (x) shall not be required to issue any further Letters of Credit or make any additional Swingline Loans hereunder and (y) shall maintain all of its rights as Issuing Lender or Swingline
Lender, as the case may be, with respect to any Letter of Credit issued by it, or Swingline Loans made by it, prior to the date of such resignation. Such resignation shall take effect upon the appointment of a successor Administrative Agent,
Canadian Administrative Agent or Collateral Agent, as applicable, pursuant to clauses (b) and (c) below or as otherwise provided below.

(b) Upon any such notice of resignation by the Administrative Agent, the Required Lenders shall appoint a successor Administrative Agent, Canadian Administrative Agent or Collateral Agent, as applicable, hereunder or thereunder who shall be

unreasonably withheld or delayed (provided that Aleris approval shall not be required if an Event of Default then exists).

(c) If a successor Administrative Agent shall not have been so appointed within such 20 Business Day period, the resigning Administrative Agent, on
behalf of the Lenders and with the consent of Aleris (which consent shall not be unreasonably withheld or delayed, provided that Aleris consent shall not be required if an Event of Default then exists), shall then appoint a successor
Administrative Agent who shall serve as Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided in clause (b) above.

(d) If no successor Administrative Agent has been appointed pursuant to clause (b) or (c) above by the 45th Business Day after the date on
which such notice of resignation was given by the resigning Administrative Agent, the Administrative Agents resignation shall become effective and the Required Lenders shall thereafter perform all the duties of the Administrative Agent
hereunder and/or under any other Credit Document until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided in clause (b) above.

(e) Upon the resignation of the Administrative Agent pursuant to this Section 12.09, the Administrative Agent shall remain indemnified to the
extent provided in this Agreement and the other Credit Documents and the provisions of this Section 12 shall continue in effect for the benefit of the Administrative Agent for all of its actions and inactions while serving as the
Administrative Agent.

the Security Documents.

(b) The Lenders hereby authorize the Collateral Agent to release any Lien granted to or held by the Collateral
Agent upon any Collateral (i) upon termination of the Commitments and payment and satisfaction of all of the ABL Obligations at any time arising under or in respect of this Agreement or the Credit Documents or the transactions contemplated
hereby or thereby, (ii) constituting property being sold or otherwise disposed of (to Persons other than any Credit Party) upon the sale or other disposition thereof in compliance with Section 10.02, (iii) upon the request of

if approved, authorized or ratified in writing by the Required Lenders (or all of the Lenders hereunder, to the extent required by
Section 13.12), (v) as otherwise may be expressly provided in the relevant Security Documents or (vi) to the extent the property constituting such Collateral is owned by any Guarantor, upon the release of the Guarantor from its

to any other Person to assure that the Collateral exists or is owned by any Credit Party or is cared for, protected or insured or that the Liens granted to the Collateral Agent herein or pursuant hereto have been properly or sufficiently or lawfully
created, perfected, protected or enforced or are entitled to any particular priority, or to exercise or to continue exercising at all or in any manner or under any duty of care, disclosure or fidelity any of the rights, authorities and powers
granted or available to the Collateral Agent in this Section 12.10 or in any of the Security Documents, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent
may act in any manner it may deem appropriate, in its sole discretion, given the Collateral Agents own interest in the Collateral as one of the Lenders and that the Collateral Agent shall have no duty or liability whatsoever to the Lenders,
except for its gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision).

(d) In no event will the Collateral Agent be replaced hereunder (or under any of the other Credit Documents) unless agreed to by the Administrative Agent and the Collateral Agent.

Acknowledgment and Amendment in substantially the form of Exhibit G-4 hereto.

UNLESS IT IS TAKEN WITH THE CONSENT OF THE REQUIRED LENDERS OR, TO THE EXTENT REQUIRED BY SECTION 13.12 OF THIS AGREEMENT, ALL OF THE LENDERS AND THE ISSUING LENDERS, OR APPROVED IN WRITING BY THE ADMINISTRATIVE AGENT, IF SUCH SETOFF OR
ACTION OR PROCEEDING WOULD OR MIGHT (PURSUANT TO CALIFORNIA CODE OF CIVIL PROCEDURE SECTIONS 580a, 580b, 580d AND 726 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE OR SECTION 2924 OF THE CALIFORNIA CIVIL CODE, IF APPLICABLE, OR OTHERWISE) AFFECT OR

hereunder without the prior written consent of all of the Lenders and, no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 13.04 (or as provided in
Section 2.13). Any Lender may grant participations in its rights hereunder, provided that (A) such Lenders obligations under this Agreement shall remain unchanged (B) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (C) the applicable Borrower, the Agents, and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lenders rights and

the sole right to enforce this Agreement and (F) no Lender shall transfer or grant any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to
the extent such amendment or waiver would (i) extend or postpone the final scheduled maturity or any date fixed for any scheduled repayment of principal of, or interest on, the Commitments and/or Loans (or Letters of Credit) that are being
participated in by such participant, (ii) reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with a waiver of applicability of any post-default increase in interest rates) or reduce the principal
amount thereof, or increase the amount of the participants participation over the amount thereof then in effect (it being understood that waivers or modifications of conditions, precedent, covenants, Defaults or Events of Default or of a
mandatory prepayment or mandatory reduction in the Total Commitment shall not constitute a change in the terms of such participation, and that an increase in any Commitment (or the available portion thereof) or Loan shall be permitted without the
consent of any participant if the participants participation is not increased as a result thereof), (iii) consent to the assignment or transfer by any Borrower of any of its rights and obligations under this Agreement or (iv) release

agreement executed by such Lender in favor of the participant relating thereto) and all amounts payable by the Borrowers hereunder shall be determined as if such Lender had not sold such participation and (B) following a Conversion Event each
Participant shall be entitled to receive from relevant Borrowers any incremental costs and indemnities (including, without limitation, pursuant to Section 2.10, 2.11 and 3.06, and 5.04) directly from the Borrowers to
the same extent as if it were the direct Lender as to which its interests were assigned after the occurrence of a Conversion Event as opposed to a participant therein, which incremental costs shall be calculated without regard to
Section 2.12. A participant shall not be entitled to receive any greater payment under Section 2.10, 2.11, 3.06 or 5.04 than what the applicable Lender would have been entitled to receive with respect to the participation sold to
such participant. A participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.04 unless the relevant Borrower is notified of the



-194-



---

participation sold to such participant and such participant agrees, for the benefit of such Borrower, to comply with Section 5.04 as though it
were a Lender.

(b) Subject to clauses (c) and (d) below, any Lender (or any Lender together with one or more other Lenders) may
(x) assign all or a portion of its Commitments and related outstanding ABL Obligations (or, if the Commitments with respect to the relevant Tranche have terminated, outstanding ABL Obligations) hereunder to (i)(A) its parent company and/or any
Affiliate of such Lender which is at least 50% owned by such Lender or its parent company or (B) to one or more other Lenders or any Affiliate of any such other Lender which is at least 50% owned by such other Lender or its parent company
(provided that any fund that invests in loans and is managed or advised by the same investment advisor of another fund which is a Lender (or by an Affiliate of such investment advisor) shall be treated as an Affiliate of such other Lender for
the purposes of this sub-clause (x)(i)(B)), or (ii) in the case of any Lender that is a fund that invests in loans, any other fund that invests in loans and is managed or advised by the same investment advisor of any Lender or by an Affiliate
of such investment advisor or (y) assign all, or if less than all, a portion equal to at least $5,000,000 (for such purposes, using the Dollar Equivalent of any Non-Dollar Denominated Loans), in each case in the aggregate for the assigning
Lender or assigning Lenders of such Commitments and related outstanding ABL Obligations (or, if the Commitments with respect to the relevant Tranche have terminated, outstanding ABL Obligations) hereunder to one or more Eligible Transferees
(treating any funds that invest in loans and are managed or advised by the same investment advisor or by an Affiliate of such investment advisor as a single Eligible Transferee), each of which Eligible Transferees shall become a party to this
Agreement as a Lender by execution of an Assignment and Assumption Agreement, provided that (i) so long as no Significant Event of Default then exists and no Conversion Event has occurred, any assignment of all or any portion of the
Canadian Commitment of any Lender pursuant to clause (x) or (y) above shall be only to a Person who is a Canadian Resident complying with the relevant requirements of Section 2.17, (ii) at such time, Schedule I-A
shall be deemed modified to reflect the Commitments (and, if an assignment of all or any portion of the Canadian Commitment is being made, Schedule I-B shall be deemed modified to reflect the new Canadian Lender) and/or outstanding Loans, as
the case may be, of such new Lender and of the existing Lenders, (iii) upon the surrender of the relevant Notes by the assigning Lender (or, upon such assigning Lenders indemnifying the respective Borrower or Borrowers for any lost Note
pursuant to a customary indemnification agreement) new Notes will be issued, at the relevant Borrowers expense, to such new Lender and to the assigning Lender upon the request of such new Lender or assigning Lender, such new Notes to be in
conformity with the requirements of Section 2.05 (with appropriate modifications) to the extent needed to reflect the revised Commitments and/or outstanding Loans, as the case may be, (iv) so long as no Significant Event of Default
with respect to Aleris then exists the consent of Aleris in each case shall be required in connection with any such assignment pursuant to clause (y) above (each of which consents shall not be unreasonably withheld or delayed), (v) the
consent of the Administrative Agent (or if an assignment of any Canadian Commitment or related outstandings, the Canadian Administrative Agent), each Swingline Lender and each Issuing Lender (for the respective Tranche) shall be required in
connection with any assignment of a Commitment to an Eligible Transferee pursuant to clause (y) above (which consents shall not be unreasonably withheld or delayed), (vi) the Administrative Agent shall receive at the time of each such
assignment, from the assigning or assignee Lender, the payment of a non-refundable assignment fee of $3,500, (vii) no such transfer or assignment will be effective until recorded by the



-195-



---

Administrative Agent on the Register pursuant to Section 13.15 and (viii) unless a Significant Event of Default with respect to Aleris has
occurred and is continuing, no Lender may assign its Commitments or Loans to a Disqualified Lender. To the extent of any assignment pursuant to this Section 13.04(b), the assigning Lender shall be relieved of its obligations hereunder
with respect to its assigned Commitments and outstanding Loans. At the time of each assignment pursuant to this Section 13.04(b) to a Person which is not already a Lender hereunder (other than a Canadian Lender in its capacity solely as
a Lender to the Canadian Borrowers), the respective assignee Lender shall, to the extent legally entitled to do so, provide to Aleris the appropriate Internal Revenue Service Forms and necessary attachments (and, if applicable, a
Section 5.04(b)(ii) Certificate) described in Section 5.04(b). At the time of each assignment pursuant to this Section 13.04(b) to a Person which is not already a Canadian Lender hereunder, the respective assignee
shall, to the extent legally entitled to do so, provide the documents required by Section 2.17(a) and shall, to the extent it is legally entitled to do so, represent that it is a Canadian Resident. To the extent that prior to the
occurrence of a Conversion Event an assignment of all or any portion of a Lenders Commitments and related outstanding ABL Obligations pursuant to Section 2.13 or this Section 13.04(b) would, at the time of such
assignment, result in amounts payable under Section 2.10, 3.06 or 5.04 (other than excess costs paid in respect of Canadian Borrower Obligations or European Borrower Obligations under Section 5.04 with respect
to assignments effected when a Significant Event of Default exists, or after a Conversion Event has occurred) that exceed the respective amounts that would be payable by the Borrowers at such time to the respective assigning Lender under such
Sections in the absence of such assignment, then the Borrowers shall not be obligated to pay such excess amount (although the Borrowers, in accordance with and pursuant to the other provisions of this Agreement, shall be obligated to pay any other
excess amounts or increased costs of the type described above resulting from changes in any applicable law, treaty, governmental rule, regulation, guidelines or order, or in the interpretation thereof, after the date of the respective assignment;
provided, however, that the preceding clause shall not apply to the portion of such excess amounts or increased costs required to be paid by the Borrowers to the extent the Borrowers would have been required to pay additional amounts pursuant to
Section 2.10, 3.06 or 5.04 irrespective of such change in such applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof). Any assignment or transfer by a Lender of its
rights or obligations under this Agreement that does not comply with this Section 13.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with
Section 13.04(a).

(c) In the event of an assignment or transfer of U.S./European Commitments or under the U.S/European Tranche
including Restricted Sub-Participations (but not including participations that are not Restricted Sub-Participations), so long as no Significant Event of Default then exists and no Conversion Event has theretofore occurred, the assignee Lender shall
make the representations in the Assignment and Assumption Agreement as to whether it is a Swiss Qualifying Bank on the effective date of the respective assignment, and if it represents that it is a Swiss Qualifying Bank and if such assignee Lender
is not incorporated in an OECD country at such time, so long as no Significant Event of Default then exists and no Conversion Event has theretofore occurred, Aleris has the right prior to the transfer to request that such new Lender provide to it a
written confirmation signed by the Swiss Federal Tax Administration that it is a bank as per explanatory note of the Swiss Federal Tax Administration No. S-02.123(9.86) as amended from time to time. If the assignee Lender is not a Swiss Qualifying
Bank and there



-196-



---

is reasonable doubt as to whether such assignee Lender counts as one or several Lenders, Aleris has the right (unless a Significant Event of Default then
exists or a Conversion Event has theretofore occurred) prior to the transfer to request that such assignee Lender provide to it a written confirmation signed by the Swiss Federal Tax Administration that such assignee Lender counts as one (or
several, as the case may be) Swiss Non-Qualifying Bank. In the event that the respective assignee (or participant pursuant to a Restricted Sub-Participation) in respect of U.S./European Commitments (or related outstandings to the European Borrower)
is unable or unwilling to represent that it is a Swiss Qualifying Bank, then, unless a Significant Event of Default is in existence or a Conversion Event has occurred, the consent of the Administrative Agent and Aleris shall be required to effect
the respective assignment or Restricted Sub-Participation (which consents shall not be unreasonably withheld or delayed); provided that no such consent shall be given by Aleris if, after giving effect to the respective assignment or
Restricted Sub-Participation, the number of Lenders to the European Borrower or holders of Restricted Sub-Participations pursuant to extensions of credit to European Borrower under this Credit Agreement which are Swiss Non-Qualifying Banks would
exceed 10.

(d) Any Lender which enters into an assignment, transfer or Restricted Sub-Participation (but not including
(x) assignments effected in accordance with the relevant requirements of Sections 13.04(b) and (c), and (y) participations that are not Restricted Sub-Participations) of its U.S./European Commitment or any outstanding
under the U.S./European Tranche shall ensure that:

(i) the terms of such assignment, transfer or sub-participation
agreement prohibit the new Lender or sub-participant from entering into further assignment, transfer or sub-participation agreements (in relation to the rights between it and such Lender) and assigning or granting any interest over the assignment,
transfer or sub-participation agreement, except in each case to a person who is a Swiss Qualifying Bank;

(ii) the new

transferor Lender from any of its obligations hereunder or substitute any such pledgee for such Lender as a party hereto.

(f) In the event
that any Lender shall become a Defaulting Lender or S&P, Moodys and Thompsons BankWatch (or InsuranceWatch Ratings Service, in the case of Lenders that are insurance companies (or Bests Insurance Reports, if such insurance

Lender or any Lender to any other or further action in any circumstances without notice or demand.

13.06 Payments Pro Rata. (a) Except as otherwise provided in this Agreement, the Administrative Agent agrees that promptly after its receipt
of each payment from or on behalf of any Borrower in respect of any ABL Obligations hereunder, the Administrative Agent shall distribute such payment to the Lenders entitled thereto (other than any Lender that has consented in writing to waive its
pro rata share of any such payment) pro rata based upon their respective shares, if any, of the ABL Obligations with respect to which such payment was received.

(b) Each of the Lenders agrees that, if it should receive any amount hereunder (whether by voluntary payment, by realization upon security, by the

Unpaid Drawings, Commitment Commission or Letter of Credit Fees, of a sum which with respect to the related sum or sums received by other Lenders is in a greater proportion than the total of such Obligation then owed and due to such Lender bears to
the total of such ABL Obligations then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for cash without recourse or warranty from the other Lenders an interest in
the ABL Obligations of the respective Credit Party to such Lenders in such amount as shall result in a proportional participation by all the Lenders in such amount; provided that if all or any portion of such excess amount is thereafter
recovered from such Lenders, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

(c) Notwithstanding anything to the contrary contained herein, the provisions of the preceding Sections 13.06(a) and (b) shall be subject to the express provisions of this Agreement which require, or permit, differing

so request, the Administrative Agent, the Lenders and Aleris shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Administrative
Agent or the Required Lenders); provided that, until so amended, (A) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein and (B) Aleris shall provide to the Administrative
Agent and the Lenders financial statements and any other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving
effect to such change in GAAP and (ii) to the extent expressly provided herein, certain calculations shall be made on a Pro Forma Basis.

may be) for the actual number of days (including the first day but excluding the last day; except that in the case of Letter of Credit Fees and Facing Fees, the last day shall be included) occurring in the period for which such interest, Commitment

consent of the Required Lenders, additional extensions of credit pursuant to this Agreement may be included in the determination of the Required Lenders and Supermajority Lenders on substantially the same basis as the extensions of Commitments are

Issuing Lender, amend, modify or waive any provision of Section 3 or alter its rights or obligations with respect to Letters of Credit,
(3) without the consent of the Administrative Agent, amend, modify or waive any provision of Section 12 or any other provision of this Agreement as same relates to the rights or obligations of the Administrative Agent,

Section 2.01(f) or (9) without the consent of the Supermajority Lenders of the affected Tranche, amend, modify or waive any provision of this Agreement in a manner which would have a disproportionate effect on such Tranche (except

Notwithstanding the foregoing, Schedules XVI, XVII and XVIII may be amended by the Administrative Agent in its Permitted Discretion.

(b) Notwithstanding anything to the contrary in this Section 13.12, (i) a Guarantor or a Borrower (other than Aleris, the European Borrower or Aleris Canada) shall automatically be released from its
obligations hereunder and its Guaranty shall be automatically released upon the consummation of any transaction permitted hereunder and the application of the proceeds therefrom in accordance with the provisions of this Agreement as a result of
which such Guarantor or Borrower ceases to be a Subsidiary of Aleris and (ii) so long as no Event of Default has occurred and is continuing and a Responsible Officer of Aleris certifies in an officers certificate to the Administrative
Agent that a Guarantor (A) is an Immaterial Subsidiary, and the release or such Guarantor would not result in any Immaterial Subsidiary being required pursuant to Section 9.12(e) to become a Credit Party hereunder (except to the
extent that on and as of the date of such release, one or more other Immaterial Subsidiaries become Guarantors hereunder and the provisions of Section 9.12(e) are satisfied upon giving effect to all such additions and releases), or
(B) is a Restricted Subsidiary which has been redesignated as an Unrestricted Subsidiary in accordance with Section 9.16, then in the case of each of clauses (A) and (B), the Administrative Agent shall promptly release such
Guarantor from its obligations hereunder and its Guaranty. In connection with any such release, the Administrative Agent shall execute and deliver to any Guarantor or Borrower, at such Guarantors or Borrowers expense, all documents that
such Guarantor or Borrower shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this Section 13.12(b) shall be without recourse to or warranty by
the Administrative Agent.

(c) Notwithstanding anything to the contrary in this Section 13.12, guarantees, collateral
security documents and related documents executed by Foreign Subsidiaries in connection with this Agreement may be in a form reasonably determined by the Collateral Agent and may be amended and waived with the consent of the Collateral Agent at the
request of Aleris without the need to obtain the consent of any other Lenders if such amendment or waiver is delivered in order (i) to reflect local law or advice of local counsel, (ii) to cure ambiguities or defects or (iii) to cause
such guarantee, collateral security document or other document to be consistent with this Agreement and the other Credit Documents.

(d)
If, in connection with any proposed change or waiver of any of the provisions of this Agreement as contemplated by clauses (i) through (v), inclusive, of the first proviso to Section 13.12(a), the consent of the Required Lenders is
obtained but the consent of one or more of such other Lenders whose consent is required is not obtained, then Aleris shall have the right, so long as all non-consenting Lenders whose individual consent is required are treated as described in either
clauses (A) or (B) below, to either (A) subject to compliance with Sections 2.17 and 2.19, replace each such non-consenting Lender or Lenders (or, at the option of Aleris if the respective Lenders consent is
required with respect to less than all Tranches of Loans (or related Commitments), to replace only the respective Tranche of Commitments and/or Loans of the respective non-consenting Lender which gives rise to the need to obtain such Lenders
individual consent) with one or more Replacement Lenders pursuant to Section 2.13 so long as at the time of such replacement, each such Replacement Lender consents to the proposed change or waiver or (B) terminate each Tranche of
such non-consenting Lenders Commitment (if such Lenders consent is required as a result of such Tranche of its Commitment) and/or repay each Tranche of outstanding Loans of such Lender which gave rise to the need to obtain such
Lenders consent and/or cash collateralize its applicable L/C Participation Percentage of the Letter of Credit Outstandings, in accordance with Sections 4.02(b) and/or 5.01(b), provided that, unless the Commitments that are
terminated and Loans that are repaid pursuant to preceding clause (B) are immediately replaced in full at such time through the addition of new Lenders or the increase of the Commitments and/or outstanding Loans of existing Lenders (who must
have consented thereto), then in the case of any action pursuant to preceding clause (B) the Required Lenders (determined after giving effect to the proposed action) shall specifically consent thereto, provided further, that in any event
Aleris shall not have the right to replace a Lender, terminate its Commitments or repay its Loans solely as a result of the exercise of such Lenders rights (and the withholding of any required consent by such Lender) pursuant to the second
proviso to Section 13.12(a).

13.13 Survival. All indemnities set forth herein including, without limitation, in
Sections 2.10, 2.11, 3.06, 5.04, 12.06 and 13.01 shall survive the execution, delivery and termination of this Agreement and the Notes and the making and repayment of the ABL Obligations.

13.14 Domicile of Loans. Each Lender may, subject to Sections 2.17 and 2.19, transfer and carry its Loans and/or participations in
outstanding Letters of Credit at, to or for the account of any office, Subsidiary or Affiliate of such Lender. Notwithstanding anything to the contrary contained herein, to the extent that a transfer of Loans and/or participations in outstanding
Letters of Credit pursuant to this Section 13.14 would, at the time of such transfer, result in amounts payable under Section 2.10, 2.11, 3.06 or 5.04 that exceed the amounts that



-204-



---

would be payable by Borrowers under such sections to the relevant Lender prior to such transfer, then the Borrowers shall not be obligated to pay such
increased costs (although the Borrowers shall be obligated to pay any other excess amounts of the type described above resulting from changes in any applicable law, treaty, governmental rule, regulation, guidelines or order, or in the interpretation
thereof, after the date of the respective transfer).

13.15 Register. Each Borrower hereby designates the relevant Administrative
Agent to serve as its agent, solely for purposes of this Section 13.15, to maintain a register (the Register) on which it will record the Commitments from time to time of each of the Lenders, the Loans made by each of
the Lenders, the amount of any principal or interest due and payable with respect to such Loans and each repayment in respect of the principal amount, and related interest amounts of the Loans of each Lender. Failure to make any such recordation, or
any error in such recordation, shall not affect the Borrowers obligations in respect of such Loans. With respect to any Lender, the transfer of the Commitments of such Lender and the rights to the principal of, and interest on, any Loan made
pursuant to such Commitments shall not be effective until such transfer is recorded on the Register maintained by the Administrative Agent with respect to ownership of such Commitments and Loans and prior to such recordation all amounts owing to the
transferor with respect to such Commitments and for Loans shall remain owing to the transferor. The registration of assignment or transfer of all or part of any Commitments and Loans shall be recorded by the Administrative Agent on the Register only
upon the acceptance by the Administrative Agent of a properly executed and delivered Assignment and Assumption Agreement pursuant to Section 13.04(b). Coincident with the delivery of such an Assignment and Assumption Agreement to the
Administrative Agent for acceptance and registration of assignment or transfer of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Lender shall surrender the Note (if any) evidencing such Loan, and thereupon
one or more new Notes in the same aggregate principal amount shall be issued to the assigning or transferor Lender and/or the new Lender at the request of any such Lender. The Borrowers jointly and severally agree to indemnify the Administrative
Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 13.15.

13.16 Confidentiality. (a) Each Lender agrees that it will not disclose without the prior written consent of Aleris (other
than to Affiliates of such Lender, its employees, auditors, advisors or counsel or to another Lender if such Lender or such Lenders holding or parent company in its reasonable discretion determines that any such party should have access to
such information, provided such Persons shall be subject to the provisions of this Section 13.16 to the same extent as such Lender) any information with respect to the Transaction, the Permitted Holders, Aleris or any of its Subsidiaries
which is now or in the future furnished pursuant to this Agreement or any other Credit Document (other than information that is available to such Lender on a nonconfidential basis prior to such disclosure), provided that any Lender may
disclose any such information (i) as is or has become generally available to the public other than by virtue of a breach of this Section 13.16(a) by the respective Lender, (ii) as may be required in any report, statement or
testimony required to be submitted to any municipal, state or Federal regulatory body having jurisdiction over such Lender or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar regulatory organizations (whether in
the United States or elsewhere) or their successors, (iii) as may be required with respect to any summons or

counterparty (or such professional advisor) agrees to be bound by the provisions of this Section 13.16, and (vii) to any pledgee under Section 13.04(e) or any prospective or actual transferee or participant in connection
with any contemplated transfer or participation of any of the Notes or Commitments or any interest therein by such Lender, provided that such prospective transferee or participant agrees to be bound by the confidentiality provisions contained
in, or provisions no less restrictive than, this Section 13.16. Any person required to maintain the confidentiality of information as provided in this Section 13.16 shall be considered to have complied with its obligation to
do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such Person would accord its own confidential information.

(b) Each Borrower hereby acknowledges and agrees that each Lender may share with any of its Affiliates, and such Affiliates may share with such Lender,
any information related to Aleris or any of its Subsidiaries (including, without limitation, any non-public customer information regarding the creditworthiness of Aleris and its Subsidiaries), if such Lender or such Lenders holding or parent
company in its reasonable discretion determines that any such party should have access to such information provided such Persons shall be subject to the provisions of this Section 13.16 to the same extent as such Lender.

(c) THE PROVISIONS OF THIS SECTION 13.17 ARE NOT INTENDED TO SUMMARIZE ALL RELEVANT PROVISIONS OF THE INTERCREDITOR AGREEMENT. REFERENCE MUST BE
MADE TO THE INTERCREDITOR AGREEMENT ITSELF TO UNDERSTAND ALL TERMS AND CONDITIONS THEREOF. EACH LENDER IS RESPONSIBLE FOR MAKING ITS OWN ANALYSIS AND REVIEW OF THE INTERCREDITOR AGREEMENT AND THE TERMS AND PROVISIONS THEREOF, AND NEITHER THE
ADMINISTRATIVE AGENT NOR THE COLLATERAL AGENT OR ANY OF ITS RESPECTIVE AFFILIATES MAKES ANY REPRESENTATION TO ANY LENDER AS TO THE SUFFICIENCY OR ADVISABILITY OF THE PROVISIONS CONTAINED IN THE INTERCREDITOR AGREEMENT. EACH LENDER IS FURTHER AWARE

incidental thereto to carry out the purposes of this Agreement and the other Credit Documents.

13.19 Special Provisions Regarding
Pledges of Equity Interests in, and Promissory Notes Owed by, Persons Not Organized in the United States. The parties hereto acknowledge and agree that the provisions of the various Security Documents executed and delivered by the Credit Parties
require that, among other things, promissory notes executed by, and Equity Interests in, various Persons owned by the applicable Credit Party be pledged, and delivered for pledge, pursuant to the Security Documents. The parties hereto further
acknowledge and agree that each Credit Party shall be required to take all actions under the laws of the jurisdiction in which such Credit Party is organized to create and perfect all security interests granted pursuant to the various Security
Documents and to take all actions under the laws of the United States, Canada, Switzerland, Germany, Belgium, France and England and any



-207-



---

State, province or territory thereof to perfect the security interests in the Equity Interests of, and promissory notes issued by, any Person organized under
the laws of said jurisdictions (in each case, to the extent said Equity Interests or promissory notes are owned by any Credit Party). Except as provided in the immediately preceding sentence, to the extent any Security Document requires or provides
for the pledge of promissory notes issued by, or Equity Interests in, any Person organized under the laws of a jurisdiction other than those specified in the immediately preceding sentence, it is acknowledged that, as of the Restatement Effective
Date, no actions have been required to be taken to perfect, under local law of the jurisdiction of the Person who issued the respective promissory notes or whose Equity Interests are pledged, under the Security Documents. Aleris hereby agrees that,
following any request by the Administrative Agent or Required Lenders to do so, Aleris shall, and shall cause its Subsidiaries to, take such actions under the local law of any jurisdiction with respect to which such actions have not already been
taken as are determined by the Administrative Agent or Required Lenders to be necessary or desirable in order to fully perfect, preserve or protect the security interests granted pursuant to the various Security Documents under the laws of such
jurisdictions. If requested to do so pursuant to this Section 13.19, all such actions shall be taken in accordance with the provisions of this Section 13.19 and Section 9.11 and within the time periods set forth
therein. All conditions and representations contained in this Agreement and the other Credit Documents shall be deemed modified to the extent necessary to effect the foregoing and so that same are not violated by reason of the failure to take
actions under local law (but only with respect to Equity Interest of, and promissory notes issued by, Persons organized under laws of jurisdictions other than the United States, Canada, Switzerland, Germany, Belgium, France and England and any
State, province or territory thereof) not required to be taken in accordance with the provisions of this Section 13.19, provided that to the extent any representation or warranty would not be true because the foregoing actions
were not taken, the respective representation of warranties shall be required to be true and correct in all material respects at such time as the respective action is required to be taken in accordance with the foregoing provisions of
Section 9.11 and this Section 13.19.

13.20 Post-Closing Actions. Notwithstanding anything to the contrary
contained in this Agreement or the other Credit Documents, the parties hereto acknowledge and agree that:

(a) Aleris and
its Subsidiaries were not required to have filed (or cause to have filed) on or prior to the Restatement Effective Date amendments to financing statements (Form UCC-1) or any amendments to filings with the United States Patent and Trademark Office
or the United States Copyright Office necessary to perfect the security interest purported to be created by the U.S. Security Agreement or the U.S. Pledge Agreement, as applicable. Not later than the 10th day after the Restatement Effective Date,
Aleris and its Subsidiaries shall have filed (or cause to have filed) all of such amendments to financing statements (Form UCC-1) and any amendments to filings with the United States Patent and Trademark Office or the United States Copyright Office
necessary to perfect the security interest purported to be created by the Security Documents.

(b) Aleris and its
Subsidiaries shall be required to take the actions (if any) specified in Schedule XV as promptly as practicable, and in any event within the time



-208-



---

periods set forth in Schedule XV. The provisions of Schedule XV shall be deemed incorporated by reference herein as fully as if set forth
herein in its entirety.

All conditions precedent and representations contained in this Agreement and the other Credit Documents shall be deemed modified
to the extent necessary to effect the foregoing (and to permit the taking of the actions described above within the time periods required above, rather than as elsewhere provided in the Credit Documents), provided that (x) to the extent
any representation and warranty would not be true because the foregoing actions were not taken on the Restatement Effective Date, the respective representation and warranty shall be required to be true and correct in all material respects at the
time the respective action is taken (or was required to be taken) in accordance with the foregoing provisions of this Section 13.20 and (y) all representations and warranties relating to the Security Documents shall be required to
be true immediately after the actions required to be taken by this Section 13.20 have been taken (or were required to be taken). The acceptance of the benefits of each Credit Event shall constitute a representation, warranty and covenant
by Aleris to each of the Lenders that the actions required pursuant to this Section 13.20 will be, or have been, taken within the relevant time periods referred to in this Section 13.20 and that, at such time, all
representations and warranties contained in this Agreement and the other Credit Documents shall then be true and correct without any modification pursuant to this Section 13.20, and the parties hereto acknowledge and agree that the
failure to take any of the actions required above, within the relevant time periods required above, shall give rise to an immediate Event of Default pursuant to this Agreement.

13.21 The PATRIOT Act. Each Lender subject to the USA PATRIOT ACT (Title 111 of Pub. L. 107-56 (signed into law October 26, 2001)) (the
PATRIOT Act) hereby notifies the Borrowers that pursuant to the requirements of the PATRIOT Act, it is required to obtain, verify and record information that identifies the Borrowers and the other Credit Parties and other
information that will allow such Lender to identify the Borrowers and the other Credit Parties in accordance with the PATRIOT Act.

13.22
Judgment Currency. (a) The Credit Parties obligations hereunder and under the other Credit Documents to make payments in any currency (the Obligation Currency) shall not be discharged or satisfied by any tender
or recovery pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by any Agent or the respective Lender of the full
amount of the Obligation Currency expressed to be payable to the such Agent or such Lender under this Agreement or the other Credit Documents. If for the purpose of obtaining or enforcing judgment against any Credit Party in any court or in any
jurisdiction, it becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the Judgment Currency) an amount due in the Obligation Currency, the
conversion shall be made at the rate of exchange (as quoted by the Administrative Agent or if the Administrative Agent does not quote a rate of exchange on such currency, by a known dealer in such currency designated by the Administrative Agent)
determined, in each case, as of the day on which the judgment is given (such day being hereinafter referred to as the Judgment Currency Conversion Date).

(b) If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount
due, each



-209-



---

Borrower covenants and agrees to pay, or cause to be paid, such additional amounts, if any (but in any event not a lesser amount), as may be necessary to
ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of Judgment Currency
stipulated in the judgment or judicial award at the rate or exchange prevailing on the Judgment Currency Conversion Date.

(c) For purposes
of determining any rate of exchange for this Section, such amounts shall include any premium and costs payable in connection with the purchase of the Obligation Currency.

13.23 Abstract Acknowledgment of Indebtedness and Joint Creditorship. (a) Notwithstanding any other provision of this Agreement, each Borrower hereby irrevocably and unconditionally agrees and covenants
with the Collateral Agent by way of an abstract acknowledgment of indebtedness (abstraktes Schuldversprechen) that it owes to the Collateral Agent as creditor in its own right and not as a representative of the other Secured Creditors, sums equal
to, and in the currency of, each amount payable by such Borrower to each of the Secured Creditors under each of the Secured Debt Agreements as and when that amount falls due for payment under the relevant Secured Debt Agreement or would have fallen
due but for any discharge resulting from failure of another Secured Creditor to take appropriate steps, in insolvency proceedings affecting such Borrower, to preserve its entitlement to be paid that amount.

(b) Each Borrower undertakes to pay to the Collateral Agent upon first written demand the amount payable by such Borrower to each of the Secured
Creditors under each of the Secured Debt Agreements as such amount has become due and payable.

(c) The Collateral Agent has the
independent right to demand and receive full or partial payment of the amounts payable by each Borrower under this Section 13.23, irrespective of any discharge of such Borrowers obligation to pay those amounts to the other Secured
Creditors resulting from failure by them to take appropriate steps, in insolvency proceedings affecting such Borrower, to preserve their entitlement to be paid those amounts.

(d) Any amount due and payable by a Borrower to the Collateral Agent under this Section 13.23 shall be decreased to the extent that the other
Secured Creditors have received (and are able to retain) payment in full of the corresponding amount under the other provisions of the Secured Debt Agreements and any amount due and payable by a Borrower to the other Secured Creditors under those
provisions shall be decreased to the extent that the Collateral Agent has received (and is able to retain) payment in full of the corresponding amount under this Section 13.23; provided that no Borrower may consider its
obligations towards a Secured Creditor to be so discharged by virtue of any set-off, counterclaim or similar defense that it may invoke vis-à-vis the Collateral Agent.

(e) The rights of the Secured Creditors (other than the Collateral Agent) to receive payment of amounts payable by each Borrower under the Secured Debt
Agreements are several and are separate and independent from, and without prejudice to, the rights of the Collateral Agent to receive payment under this Section 13.23.



-210-



---

(f) In addition, but without prejudice to the foregoing, the Collateral Agent shall be the joint creditor
(together with the relevant Secured Creditor) of all obligations of each Borrower towards each of the Secured Creditors under the Secured Debt Agreements.

13.24 Special Appointment of Collateral Agent for German Security. (a) (i) Each Lender that is or will become party to this Agreement hereby appoints the Collateral Agent as trustee
(Treuhaender) and administrator for the purpose of holding on trust (Treuhand), administering, enforcing and releasing the German Security (as defined below) for the Secured Creditors, (ii) the Collateral Agent accepts its
appointment as a trustee and administrator of the German Security on the terms and subject to the conditions set out in this Agreement and (iii) the Lenders, the Collateral Agent and all other parties to this Agreement agree that, in relation
to the German Security, no Lender shall exercise any independent power to enforce any German Security or take any other action in relation to the enforcement of the German Security, or make or receive any declarations in relation thereto.

(b) The Collateral Agent shall hold and administer any German Security which is security assigned, transferred or pledged under German law
to it as a trustee for the benefit of the Secured Creditors, where German Security means the assets which are the subject of a security document which is governed by German law.

(c) Each Lender hereby instructs the Collateral Agent (with the right of sub delegation) to enter into any documents evidencing German Security and to
make and accept all declarations and take all actions as it considers necessary or useful in connection with any German Security on behalf of the Secured Creditors. The Collateral Agent shall further be entitled to rescind, release, amend and/or
execute new and different documents securing the German Security.

(d) The Lenders and the Collateral Agent agree that all rights and
claims constituted by the abstract acknowledgment of indebtedness pursuant to Section 13.24 of this Agreement and all proceeds held by the Collateral Agent pursuant to or in connection with such abstract acknowledgment of indebtedness
are held by the Collateral Agent with effect from the date of such abstract acknowledgment of indebtedness in trust for the Secured Creditors and will be administered in accordance with this Agreement and the other Secured Debt Agreements. The
Secured Creditors and the Collateral Agent agree further that the respective Credit Partys obligations under such abstract acknowledgment of indebtedness shall not increase the total amount of the Secured Obligations (as defined in the
respective agreement governing German Security) and shall not result in any additional liability of any of the Credit Parties or otherwise prejudice the rights of any of the Credit Parties. Accordingly, payment of the obligations under such abstract
acknowledgment of indebtedness shall, to the same extent, discharge the corresponding Secured Obligations and vice versa.

13.25
Conflicting Provisions in Security Documents. In the event that any provisions of this Agreement conflict with any Security Document, the provisions of this Agreement shall govern.

13.26 Continuing Effect. This Agreement shall amend and restate in its entirety the Existing ABL Credit Agreement, and all obligations of the
Borrowers thereunder and under



-211-



---

the Credit Documents as in effect immediately prior to the Restatement Effective Date (the Existing Credit Documents) shall be deemed
replaced and extended as obligations under this Agreement and the Credit Documents and be governed hereby and thereby without novation.

SECTION 14. U.S. Borrower Guaranty.

14.01 Guaranty. In order to induce the Administrative Agent, the Collateral
Agent, the Issuing Lenders and the Lenders to enter into this Agreement and to extend credit hereunder, and to induce the other Guaranteed Creditors to enter into Interest Rate Protection Agreements, Other Hedging Agreements and Treasury Services
Agreements and in recognition of the direct benefits to be received by each U.S. Borrower from the proceeds of the Loans, the issuance of the Letters of Credit and the entering into of such Interest Rate Protection Agreements, Other Hedging
Agreements and Treasury Services Agreements, each U.S. Borrower hereby agrees with the Guaranteed Creditors as follows: each U.S. Borrower hereby jointly and severally, unconditionally and irrevocably guarantees the full and prompt payment when due,
whether upon maturity, acceleration or otherwise, of any and all of the Relevant ABL Guaranteed Obligations to the Guaranteed Creditors. If any or all of the Relevant ABL Guaranteed Obligations to the Guaranteed Creditors becomes due and payable
hereunder, each U.S. Borrower, jointly and severally, unconditionally and irrevocably, promises to pay such indebtedness to the Administrative Agent and/or the other Guaranteed Creditors, or order, on demand, together with any and all expenses which
may be incurred by the Administrative Agent and the other Guaranteed Creditors in collecting any of the Relevant ABL Guaranteed Obligations.

14.02 Reinstatement. If a claim is ever made upon any Guaranteed Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Relevant ABL Guaranteed Obligations and any of the aforesaid
payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such payee or any of its property or (ii) any settlement or compromise of any such claim
effected by such payee with any such claimant (including any Guaranteed Party), then and in such event each U.S. Borrower agrees that any such judgment, decree, order, settlement or compromise shall be binding upon such U.S. Borrower,
notwithstanding any revocation of this U.S. Borrower Guaranty or other instrument evidencing any liability of any other Guaranteed Party, and such U.S. Borrower shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or
recovered to the same extent as if such amount had never originally been received by any such payee.

14.03 Bankruptcy.
Additionally, each U.S. Borrower jointly and severally, unconditionally and irrevocably guarantees the payment of any and all of the Relevant ABL Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by the Borrowers upon
the occurrence of any of the events specified in Section 11.05, and irrevocably and unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand, in lawful money of the United States.

14.04 Nature of Liability. The liability of each U.S. Borrower hereunder is primary, absolute and unconditional, exclusive and independent of any
security for or other guaranty of the Relevant ABL Guaranteed Obligations, whether executed by any other guarantor



-212-



---

or by any other party, and the liability of each U.S. Borrower hereunder shall not be affected or impaired by (a) any direction as to application of
payment by any Guaranteed Party or by any other party, or (b) any other continuing or other guaranty, undertaking or maximum liability of a guarantor or of any other party as to the Relevant ABL Guaranteed Obligations, or (c) any payment
on or in reduction of any such other guaranty or undertaking, or (d) any dissolution, termination or increase, decrease or change in personnel by any Guaranteed Party, or (e) any payment made to any Guaranteed Creditor on the Relevant ABL
Guaranteed Obligations which any such Guaranteed Creditor repays to any Guaranteed Party pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each U.S. Borrower waives any right to
the deferral or modification of its obligations hereunder by reason of any such proceeding, or (f) any action or inaction by the Guaranteed Creditors as contemplated in Section 14.06, or (g) any invalidity, irregularity or
enforceability of all or any part of the Relevant ABL Guaranteed Obligations or of any security therefor. To the extent more than one U.S. Borrower guarantees the same Relevant ABL Guaranteed Obligations hereunder, the liabilities of such U.S.
Borrower with respect thereto shall be joint and several.

14.05 Independent Obligation. The obligations of each U.S. Borrower
hereunder are independent of the obligations of any other guarantor, any other party or any Guaranteed Party, and a separate action or actions may be brought and prosecuted against each U.S. Borrower whether or not action is brought against any
other guarantor, any other party or any Guaranteed Party and whether or not any other guarantor, any other party or any Guaranteed Party be joined in any such action or actions. Each U.S. Borrower waives, to the fullest extent permitted by law, the
benefit of any statute of limitations affecting its liability hereunder or the enforcement thereof. Any payment by any Guaranteed Party or other circumstance which operates to toll any statute of limitations as to any Guaranteed Party shall operate
to toll the statute of limitations as to each U.S. Borrower.

14.06 Authorization. Each U.S. Borrower authorizes the Guaranteed
Creditors without notice or demand (except as shall be required by applicable statute and cannot be waived), and without affecting or impairing its liability hereunder, from time to time to:

(a) change the manner, place or terms of payment of, and/or change or extend the time of payment of, renew, increase, accelerate or alter,
any of the Relevant ABL Guaranteed Obligations (including any increase or decrease in the principal amount thereof or the rate of interest or fees thereon), any security therefor, or any liability incurred directly or indirectly in respect thereof,
and this U.S. Borrower Guaranty shall apply to the Relevant ABL Guaranteed Obligations as so changed, extended, renewed or altered;

(b) take and hold security for the payment of the Relevant ABL Guaranteed Obligations and sell, exchange, release, impair, surrender, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time
pledged or mortgaged to secure, or howsoever securing, the Relevant ABL Guaranteed Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset there against;



-213-



---

(c) exercise or refrain from exercising any rights against any Guaranteed Party or others
or otherwise act or refrain from acting;

(d) release or substitute any one or more endorsers, guarantors, any Guaranteed
Party or other obligors;

(e) settle or compromise any of the Relevant ABL Guaranteed Obligations, any security therefor or
any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of any Guaranteed Party to
its creditors other than the Guaranteed Creditors;

(f) apply any sums by whomsoever paid or howsoever realized to any
liability or liabilities of any Guaranteed Party to the Guaranteed Creditors regardless of what liability or liabilities of such Guaranteed Party remain unpaid;

(g) consent to or waive any breach of, or any act, omission or default under, this Agreement, any other Credit Document, any other Secured
Debt Agreement or any of the instruments or agreements referred to herein or therein, or otherwise amend, modify or supplement this Agreement, any other Credit Document, or any other Secured Debt Agreement or any of such other instruments or
agreements; and/or

(h) take any other action which would, under otherwise applicable principles of common law, give rise to
a legal or equitable discharge of such Borrower from its liabilities under this U.S. Borrower Guaranty.

14.07 Reliance. It is not
necessary for any Guaranteed Creditor to inquire into the capacity or powers of any U.S. Borrower or any of its respective Subsidiaries or the officers, directors, partners or agents acting or purporting to act on their behalf, and any Relevant ABL
Guaranteed Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

14.08
Waiver. (a) Each U.S. Borrower waives any right (except as shall be required by applicable statute and cannot be waived) to require any Guaranteed Creditor to (i) proceed against any Guaranteed Party, any other guarantor or any
other party, (ii) proceed against or exhaust any security held from any Guaranteed Party, any other guarantor or any other party or (iii) pursue any other remedy in any Guaranteed Creditors power whatsoever. Each U.S. Borrower waives
any defense based on or arising out of any defense of any Guaranteed Party, any other guarantor or any other party, other than payment of the Relevant ABL Guaranteed Obligations to the extent of such payment, based on or arising out of the
disability of any Guaranteed Party, any U.S. Borrower, any other guarantor or any other party, or the validity, legality or unenforceability of the Relevant ABL Guaranteed Obligations or any part thereof from any cause, or the cessation from any
cause of the liability of any Guaranteed Party other than payment of the Relevant ABL Guaranteed Obligations to the extent of such payment. The Guaranteed Creditors may, at their election, foreclose on any security held by the Administrative Agent,
the Collateral Agent or any other Guaranteed Creditor by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the



-214-



---

extent such sale is permitted by applicable law), or exercise any other right or remedy the Guaranteed Creditors may have against any Guaranteed Party or any
other party, or any security, without affecting or impairing in any way the liability of any U.S. Borrower hereunder except to the extent the Relevant ABL Guaranteed Obligations have been paid. Each U.S. Borrower waives any defense arising out of
any such election by the Guaranteed Creditors, even though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of such U.S. Borrower against any Guaranteed Party or any other party or any
security.

(b) Each U.S. Borrower waives all presentments, demands for performance, protests and notices, including without limitation
notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this U.S. Borrower Guaranty, and notices of the existence, creation or incurring of new or additional Relevant ABL Guaranteed Obligations. Each U.S.
Borrower assumes all responsibility for being and keeping itself informed of each Guaranteed Partys financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Relevant ABL Guaranteed Obligations
and the nature, scope and extent of the risks which such U.S. Borrower assumes and incurs hereunder, and agrees that neither the Administrative Agent nor any of the other Guaranteed Creditors shall have any duty to advise such U.S. Borrower of
information known to them regarding such circumstances or risks.

(c) Each U.S. Borrower hereby acknowledges and affirms that it
understands that to the extent any Relevant ABL Guaranteed Obligations are secured by Real Property located in the State of California, such U.S. Borrower shall be liable for the full amount of the liability hereunder notwithstanding foreclosure on
such Real Property by trustee sale or any other reason impairing such U.S. Borrowers or any Guaranteed Creditors right to proceed against any Borrower or any other guarantor of the Relevant ABL Guaranteed Obligations.

(d) Each U.S. Borrower hereby waives, to the fullest extent permitted by applicable law, all rights and benefits under Sections 580a, 580b, 580d and 726
of the California Code of Civil Procedure. Each U.S. Borrower hereby further waives, to the fullest extent permitted by applicable law, without limiting the generality of the foregoing or any other provision hereof, all rights and benefits which
might otherwise be available to such U.S. Borrower under Sections 2809, 2810, 2815, 2819, 2821, 2839, 2845, 2846, 2847, 2848, 2849, 2850, 2899 and 3433 of the California Civil Code.

(e) Until all Relevant ABL Guaranteed Obligations have been paid in full in cash, each U.S. Borrower agrees that it will not exercise its rights of
subrogation and reimbursement and any other rights and defenses available to such U.S. Borrower by reason of Sections 2787 to 2855, inclusive, of the California Civil Code, including, without limitation, (1) any defenses such U.S. Borrower may
have to this U.S. Borrower Guaranty by reason of an election of remedies by the Guaranteed Creditors and (2) any rights or defenses such U.S. Borrower may have by reason of protection afforded to a Borrower pursuant to the antideficiency or
other laws of California limiting or discharging such Borrowers indebtedness, including, without limitation, Sections 580a, 580b, 580d and 726 of the California Code of Civil Procedure. In furtherance of such provisions, such U.S. Borrower
hereby waives all rights and defenses arising out of an election of remedies of the Guaranteed Creditors, even though that election of



-215-



---

remedies, such as a nonjudicial foreclosure destroys such U.S. Borrowers rights of subrogation and reimbursement against a Borrower by the operation of
Section 580d of the California Code of Civil Procedure or otherwise.

(f) Each U.S. Borrower warrants and agrees that each of the
waivers set forth above is made with full knowledge of its significance and consequences and that if any of such waivers are determined to be contrary to any applicable law or public policy, such waivers shall be effective only to the maximum extent
permitted by law.

14.09 Maximum Liability. It is the desire and intent of each U.S. Borrower and the Guaranteed Creditors that this
U.S. Borrower Guaranty shall be enforced against each U.S. Borrower to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. If, however, and to the extent that, the
obligations of any U.S. Borrower under this U.S. Borrower Guaranty shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances
or transfers), then the amount of each U.S. Borrower obligations under this U.S. Borrower Guaranty shall be deemed to be reduced and such U.S. Borrower shall pay the maximum amount of the Relevant ABL Guaranteed Obligations which would be
permissible under applicable law.

SECTION 15. Nature of U.S. Borrower Obligations; Limitation on Canadian Borrower Obligations and
European Borrower Obligations.

15.01 Nature of U.S. Borrower Obligations and Canadian Borrower Obligations. Notwithstanding
anything to the contrary contained elsewhere in this Agreement, it is understood and agreed by the various parties to this Agreement that

(i) all U.S. Borrower Obligations to repay principal of, interest on, and all other amounts with respect to, all U.S./European Revolving Loans, Letter of Credit Outstandings and all other U.S. Borrower Obligations
pursuant to this Agreement and under any U.S. Borrower Revolving Note (including, without limitation, all fees, indemnities, taxes and other U.S. Borrower Obligations in connection therewith or in connection with the related Commitments) shall
constitute the joint and several obligations of each of the U.S. Borrowers. In addition to the direct (and joint and several) obligations of the U.S. Borrowers with respect to U.S. Borrower Obligations as described above, all such U.S. Borrower
Obligations shall be guaranteed pursuant to, and in accordance with the terms of, the U.S. Borrower Guaranty and the U.S. Subsidiaries Guaranty; and

(ii) all Canadian Borrower Obligations to repay principal of, interest on, and all other amounts with respect to, all Canadian Revolving Loans and all other Canadian Borrower Obligations pursuant to this Agreement and
under any Canadian Revolving Note (including, without limitation, all fees, indemnities, taxes and other Canadian Borrower Obligations in connection therewith or in connection with the related Commitments) shall constitute the joint and several
obligations of each of the Canadian Borrowers. In addition to the direct (and joint and several) obligations of the Canadian Borrowers with respect to Canadian Borrower Obligations as described above, all such



-216-



---

Canadian Borrower Obligations shall be guaranteed pursuant to, and in accordance with the terms of, the Canadian Subsidiaries Guaranty, the Canadian Parent
Guaranty and the U.S. Subsidiaries Guaranty.

15.02 Independent Obligation. The obligations of each U.S. Borrower with respect to
the U.S. Borrower Obligations are independent of the obligations of each other U.S. Borrower or any Guarantor under its guaranty of such U.S. Borrower Obligations, and a separate action or actions may be brought and prosecuted against each U.S.
Borrower, whether or not any other U.S. Borrower or any such Guarantor is joined in any such action or actions. Each U.S. Borrower waives, to the fullest extent permitted by law, the benefit of any statute of limitations affecting its liability
hereunder or the enforcement thereof. Any payment by any U.S. Borrower or other circumstance which operates to toll any statute of limitations as to any U.S. Borrower shall, to the fullest extent permitted by law, operate to toll the statute of
limitations as to each U.S. Borrower.

15.03 Authorization. Each of the U.S. Borrowers authorizes the Administrative Agent and the
Lenders without notice or demand (except as shall be required by applicable statute and cannot be waived), and without affecting or impairing its liability hereunder, from time to time to:

(a) exercise or refrain from exercising any rights against any other U.S. Borrower or any Guarantor or others or otherwise act or refrain
from acting;

(b) release or substitute any other U.S. Borrower, endorsers, Guarantors or other obligors;

(c) settle or compromise any of the U.S. Borrower Obligations of any other U.S. Borrower or any other Credit Party, any security therefor
or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of any U.S. Borrower to
its creditors other than the Lenders;

(d) apply any sums paid by any other U.S. Borrower or any other Person, howsoever
realized or otherwise received to or for the account of such U.S. Borrower to any liability or liabilities of such other U.S. Borrower or other Person regardless of what liability or liabilities of such other Borrower or other Person remain unpaid;
and/or

(e) consent to or waive any breach of, or act, omission or default under, this Agreement or any of the instruments
or agreements referred to herein, or otherwise, by any other Borrower or any other Person.

15.04 Reliance. It is not necessary for
the Administrative Agent or any other Lender to inquire into the capacity or powers of any U.S. Borrower or any of its Subsidiaries or the officers, directors, members, partners or agents acting or purporting to act on its behalf, and any U.S.
Borrower Obligations made or created in reliance upon the professed exercise of such powers shall constitute the joint and several obligations of the U.S. Borrowers hereunder.



-217-



---

15.05 Contribution; Subrogation. No U.S. Borrower shall have any rights of contribution or
subrogation with respect to any other U.S. Borrower as a result of payments made by it hereunder, in each case unless and until the Total Commitment has been terminated and all U.S. Borrower Obligations have been paid in full.

15.06 Waiver. Each U.S. Borrower waives any right to require the Administrative Agent or the other Lenders to (i) proceed against any other
U.S. Borrower, any Guarantor or any other party, (ii) proceed against or exhaust any security held from any U.S. Borrower, any Guarantor or any other party or (iii) pursue any other remedy in the Administrative Agents or the
Lenders power whatsoever. Each U.S. Borrower waives any defense based on or arising out of suretyship or any impairment of security held from any U.S. Borrower, any Guarantor or any other party or on or arising out of any defense of any other
U.S. Borrower, any Guarantor or any other party other than payment in full in cash of the U.S. Borrower Obligations, including, without limitation, any defense based on or arising out of the disability of any other U.S. Borrower, any Guarantor or
any other party, or the unenforceability of the U.S. Borrower Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any other U.S. Borrower, in each case other than as a result of the payment in full in
cash of the U.S. Borrower Obligations.

15.07 Limitation on Canadian Borrower Obligations and European Borrower Obligations.
Notwithstanding anything to the contrary herein or in any other Credit Document (including provisions that may override any other provision), in no event shall the Canadian Borrowers or any other Canadian Subsidiary of any Borrower, the European
Borrower, any other European Distribution Subsidiary of the European Borrower, any other Foreign Subsidiary of Aleris or any Domestic Subsidiary of a Foreign Subsidiary of Aleris guarantee or be deemed to have guaranteed or become liable or
obligated on a joint and several basis or otherwise for, or to have pledged any of its assets to secure, any Obligation of a U.S. Credit Party under this Agreement or any of the other Credit Documents. All provisions contained in any Credit Document
shall be interpreted consistently with this Section 15.07 to the extent possible, and where such other provisions conflict with the provisions of this Section 15.07, the provisions of this Section 15.07 shall
govern.

15.08 Limited Recourse Against Corus Aluminium Inc. Notwithstanding the fact that, as the general partner of Corus LP,
Corus Aluminium Inc. is jointly and severally liable with Corus LP for all of Corus LPs obligations and liabilities provided for herein and under the other Credit Documents, any recourse against Corus Aluminium Inc. pursuant to this Agreement
or any other Credit Document, including without limitation the Canadian Security Agreements, shall be limited exclusively to the assets of Corus LP and the assets of Corus Aluminium Inc. held or owned by it as general partner for and on behalf of
Corus LP and there shall be no recourse against other assets of Corus Aluminium Inc.

15.09 Maximum Liability. It is the desire and
intent of (i) each U.S. Borrower and the U.S./European Lenders and (ii) each Canadian Borrower and the Canadian Lenders, that, in each case, their respective joint and several liability shall be enforced against each U.S. Borrower or
Canadian Borrower, as applicable, to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. If, however, and to the extent that, the obligations of any U.S. Borrower or Canadian
Borrower under any Credit

Document shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law
relating to fraudulent conveyances or transfers), then the amount of each U.S. Borrowers obligations (in the case of any invalidity or unenforceability with respect to a U.S. Borrowers obligations) or each Canadian Borrowers
obligations (in the case of any invalidity or unenforceability with respect to a Canadian Borrowers obligations) under the Credit Documents shall be deemed to be reduced and such U.S. Borrower or Canadian Borrower, as applicable, shall pay the
maximum amount of the ABL Obligations which would be permissible under applicable law.

SECTION 16. U.S./European Revolving Loans;
Intra-Lender Issues.

16.01 Specified Foreign Currency Participations. Notwithstanding anything to the contrary contained
herein, all U.S./European Revolving Loans which are denominated in a Specified Foreign Currency (each, a Specified Foreign Currency Loan) shall be made solely by the U.S./European Lenders (including DBNY) who are not Participating
Specified Foreign Currency Lenders (as defined below). Each U.S./European Lender acceptable to DBNY that does not have Specified Foreign Currency Funding Capacity (a Participating Specified Foreign Currency Lender) shall
irrevocably and unconditionally purchase and acquire and shall be deemed to irrevocably and unconditionally purchase and acquire from DBNY, and DBNY shall sell and be deemed to sell to each such Participating Specified Foreign Currency Lender,
without recourse or any representation or warranty whatsoever, an undivided interest and participation (a Specified Foreign Currency Participation) in each U.S./European Revolving Loan which is a Specified Foreign Currency Loan
funded by DBNY in an amount equal to such Participating Specified Foreign Currency Lenders U.S./European Percentage of the Borrowing that includes such U.S./European Revolving Loan. Such purchase and sale of a Specified Foreign Currency
Participation shall be deemed to occur automatically upon the making of a Specified Foreign Currency Loan by DBNY, without any further notice to any Participating Specified Foreign Currency Lender. The purchase price payable by each Participating
Specified Foreign Currency Lender to DBNY for each Specified Foreign Currency Participation purchased by it from DBNY shall be equal to 100% of the principal amount of such Specified Foreign Currency Participation (i.e., the product of
(i) the amount of the Borrowing that includes the relevant U.S./European Revolving Loan and (ii) such Participating Specified Foreign Currency Lenders U.S./European Percentage), and such purchase price shall be payable by each
Participating Specified Foreign Currency Lender to DBNY in accordance with the settlement procedure set forth in Section 16.02 below. DBNY and the Administrative Agent shall record on their books the amount of the U.S./European Revolving
Loans made by DBNY and each Participating Specified Foreign Currency Lenders Specified Foreign Currency Participation and Funded Specified Foreign Currency Participation therein, all payments in respect thereof and interest accrued thereon and
all payments made by and to each Participating Specified Foreign Currency Lender pursuant to this Section 16.01.

16.02
Settlement Procedures for Specified Foreign Currency Participations. Each Participating Specified Foreign Currency Lenders Specified Foreign Currency Participation in the Specified Foreign Currency Loans shall be in an amount equal to
its U.S./European Percentage of all such Specified Foreign Currency Loans. However, in order to facilitate the administration of the Specified Foreign Currency Loans made by DBNY and the Specified Foreign Currency Participations, settlement among
DBNY and the Participating



-219-



---

Specified Foreign Currency Lenders with regard to the Participating Specified Foreign Currency Lenders Specified Foreign Currency Participations shall
take place in accordance with the following provisions:

(i) DBNY and the Participating Specified Foreign Currency Lenders
shall settle (a Specified Foreign Currency Participation Settlement) by payments in respect of the Specified Foreign Currency Participations as follows: So long as any Specified Foreign Currency Loans are outstanding, Specified
Foreign Currency Participation Settlements shall be effected upon the request of DBNY through the Administrative Agent on such Business Days as requested by DBNY and as the Administrative Agent shall specify by a notice by telecopy, telephone or
similar form of notice to each Participating Specified Foreign Currency Lender requesting such Specified Foreign Currency Participation Settlement (each such date on which a Specified Foreign Currency Participation Settlement occurs herein called a
Specified Foreign Currency Participation Settlement Date), such notice to be delivered no later than 2:00 p.m. (New York time) at least one Business Day prior to the requested Specified Foreign Currency Participation Settlement
Date; provided that DBNY shall have the option but not the obligation to request a Specified Foreign Currency Participation Settlement Date and, in any event, shall not request a Specified Foreign Currency Participation Settlement Date prior
to the occurrence of an Event of Default; provided further, that if (x) such Event of Default is cured or waived in writing in accordance with the terms hereof, (y) no ABL Obligations have yet been declared due and payable under
Article 11 and (z) the Administrative Agent has actual knowledge of such cure or waiver, all prior to the Administrative Agents giving notice to the Participating Specified Foreign Currency Lenders of the first Specified Foreign Currency
Participation Settlement Date under this Agreement, then the Administrative Agent shall not give notice to the Participating Specified Foreign Currency Lenders of a Specified Foreign Currency Participation Settlement Date based upon such cured or
waived Event of Default. If on any Specified Foreign Currency Participation Settlement Date the total principal amount of the Specified Foreign Currency Loans made or deemed made by DBNY during the period ending on (but excluding) such Specified
Foreign Currency Participation Settlement Date and commencing on (and including) the immediately preceding Specified Foreign Currency Participation Settlement Date (or the Restatement Effective Date in the case of the period ending on the first
Specified Foreign Currency Participation Settlement Date) (each such period herein called a Specified Foreign Currency Participation Settlement Period) is greater than the principal amount of Specified Foreign Currency Loans
repaid during such Specified Foreign Currency Participation Settlement Period to DBNY, each Participating Specified Foreign Currency Lender shall pay to DBNY (through the Administrative Agent), no later than 11:00 a.m. (New York time) on such
Specified Foreign Currency Participation Settlement Date, an amount equal to such Participating Specified Foreign Currency Lenders ratable share of the amount of such excess. If in any Specified Foreign Currency Participation Settlement Period
the outstanding principal amount of the Specified Foreign Currency Loans repaid to DBNY in such period exceeds the total principal amount of the Specified Foreign Currency Loans made or deemed made by DBNY during such period, DBNY shall pay to each
Participating Specified Foreign Currency Lender (through the Administrative Agent) on such Specified Foreign Currency Participation Settlement Date an amount equal to such Participating Specified



-220-



---

Foreign Currency Lenders ratable share of such excess. Specified Foreign Currency Participation Settlements in respect of Specified Foreign Currency
Loans shall be made in the respective Available Currency in which such Specified Foreign Currency Loan was funded on the Specified Foreign Currency Participation Settlement Date for such Specified Foreign Currency Loans.

(ii) If any Participating Specified Foreign Currency Lender fails to pay to DBNY on any Specified Foreign Currency Participation
Settlement Date the full amount required to be paid by such Participating Specified Foreign Currency Lender to DBNY on such Specified Foreign Currency Participation Settlement Date in respect of such Participating Specified Foreign Currency
Lenders Specified Foreign Currency Participation (such Participating Specified Foreign Currency Lenders Specified Foreign Currency Participation Settlement Amount) with DBNY, DBNY shall be entitled to recover such
unpaid amount from such Participating Specified Foreign Currency Lender, together with interest thereon (in the same respective currency or currencies as the relevant Specified Foreign Currency Loans) at the Base Rate plus 2.00%. Without
limiting DBNYs rights to recover from any Participating Specified Foreign Currency Lender any unpaid Specified Foreign Currency Participation Settlement Amount payable by such Participating Specified Foreign Currency Lender to DBNY, the
Administrative Agent shall also be entitled to withhold from amounts otherwise payable to such Participating Specified Foreign Currency Lender an amount equal to such Participating Specified Foreign Currency Lenders unpaid Specified Foreign
Currency Participation Settlement Amount owing to DBNY and apply such withheld amount to the payment of any unpaid Specified Foreign Currency Participation Settlement Amount owing by such Participating Specified Foreign Currency Lender to DBNY.

If any Specified Foreign Currency Loans convert to U.S. Dollars pursuant to Section 2.14, a Specified Foreign Currency
Participation Settlement Date shall be deemed to automatically occur on the date of such conversion and DBNY shall receive an amount expressed in the respective Available Currency immediately prior to such conversion.

16.03 Obligations Irrevocable. The obligations of each Participating Specified Foreign Currency Lender to purchase from DBNY a participation in
each Specified Foreign Currency Loan made by DBNY and to make payments to DBNY with respect to such participation, in each case as provided herein, shall be irrevocable and not subject to any qualification or exception whatsoever, including any of
the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any of the other Credit
Documents or of any Loans, against the Borrowers or any other Credit Party;

(ii) the existence of any claim, setoff,
defense or other right which the Borrowers or any other Credit Party may have at any time against the Administrative Agent, any Participating Specified Foreign Currency Lender, or any other Person, whether in connection with this Agreement, any
Specified Foreign Currency Loans, the transactions contemplated herein or any unrelated transactions;



-221-



---

(iii) any application or misapplication of any proceeds of any Specified Foreign Currency
Loans;

(iv) the surrender or impairment of any security for any Specified Foreign Currency Loans;

(v) the occurrence of any Default or Event of Default;

(vi) the commencement or pendency of any events specified in Section 11.05, in respect of the Borrowers or any of its
Subsidiaries or any other Person; or

(vii) the failure to satisfy the applicable conditions precedent set forth in
Section 6 or 7.

16.04 Recovery or Avoidance of Payments. In the event any payment by or on behalf of any
Borrower or any other Credit Party received by the Administrative Agent with respect to any Specified Foreign Currency Loan made by DBNY is thereafter set aside, avoided or recovered from the Administrative Agent in connection with any insolvency
proceeding or due to any mistake of law or fact, each Participating Specified Foreign Currency Lender shall, upon written demand by the Administrative Agent, pay to DBNY (through the Administrative Agent) such Participating Specified Foreign
Currency Lenders U.S./European Percentage of such amount set aside, avoided or recovered, together with interest at the rate and in the currency required to be paid by DBNY or the Administrative Agent upon the amount required to be repaid by
it.

16.05 Indemnification by Lenders. Each Participating Specified Foreign Currency Lender agrees to indemnify DBNY (to the extent
not reimbursed by the Borrowers and without limiting the obligations of the Borrowers hereunder or under any other Credit Document) ratably for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including attorneys fees) or disbursements of any kind and nature whatsoever that may be imposed on, incurred by or asserted against DBNY in any way relating to or arising out of any Specified Foreign Currency Loans or any action
taken or omitted by DBNY in connection therewith; provided that no Participating Specified Foreign Currency Lender shall be liable for any of the foregoing to the extent it arises from the gross negligence or willful misconduct of DBNY (as
determined by a court of competent jurisdiction in a final non-appealable judgment). Without limiting the foregoing, each Participating Specified Foreign Currency Lender agrees to reimburse DBNY promptly upon demand for such Participating Specified
Foreign Currency Lenders ratable share of any costs or expenses payable by the Borrowers to DBNY in respect of the Specified Foreign Currency Loans to the extent that DBNY is not promptly reimbursed for such costs and expenses by the
Borrowers. The agreement contained in this Section 16.05 shall survive payment in full of all Specified Foreign Currency Loans.

16.06 Specified Foreign Currency Loan Participation Fee. In consideration for each Participating Specified Foreign Currency Lenders participation in the Specified Foreign Currency Loans made by DBNY, DBNY agrees to pay to the
Administrative Agent for the account of each Participating Specified Foreign Currency Lender, as and when DBNY receives



-222-



---

payment of interest on its Specified Foreign Currency Loans, a fee (the Specified Foreign Currency Participation Fee) at a rate per annum
equal to the Applicable Margin on such Specified Foreign Currency Loans minus 0.25% on the Unfunded Specified Foreign Currency Participation of such Participating Specified Foreign Currency Lender in such Specified Foreign Currency Loans of
DBNY. The Specified Foreign Currency Participation Fee in respect of any unfunded Specified Foreign Currency Participation in a Specified Foreign Currency Loan shall be payable to the Administrative Agent in the Available Currency in which the
respective Specified Foreign Currency Loan was funded when interest on such Specified Foreign Currency Loan is received by DBNY. If DBNY does not receive payment in full of such interest, the Specified Foreign Currency Participation Fee in respect
of the unfunded Specified Foreign Currency Participation in such Specified Foreign Currency Loans shall be reduced proportionately. Any amounts payable under this Section 16.06 by the Administrative Agent to the Participating Specified
Foreign Currency Lenders shall be paid in the Available Currency in which the respective Specified Foreign Currency Loan was funded (or, if different, the currency in which such interest payments are actually received).
