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.

be evidenced in the Register maintained by the Administrative Agent pursuant to Section 11.15 and shall, if requested by such Lender, also be evidenced (i) in the case of U.S. Loans, by a promissory note duly executed and delivered
by each U.S. Borrower substantially in the form of Exhibit B-1, with blanks appropriately completed in conformity herewith (each a U.S. Term Note and, collectively, the U.S. Term Notes) and
(ii) in the case of German Loans, by a promissory note duly executed and delivered by each German Borrower substantially in the form of Exhibit B-2, with blanks appropriately completed in conformity herewith (each, a German Term
Note and, collectively, the German Term Notes).

(b) The U.S. Term Note issued to each Lender that has a U.S.
Commitment or outstanding U.S. Loans shall (i) be executed by the U.S. Borrower, (ii) be payable to such Lender or its registered assigns and be dated the Restatement Effective Date (or, if issued after the Restatement Effective Date, be
dated the date of the issuance thereof), (iii) be in a stated principal amount (expressed in U.S. Dollars) equal to the U.S. Loans of such Lender at such time and be payable in the outstanding principal amount of the U.S. Loans evidenced
thereby from time to time, (iv) mature on the Final Maturity Date, (v) bear interest as provided in the appropriate clause of Section 2.08 in respect of the Base Rate Loans and Eurodollar Loans, as the case may be, evidenced
thereby, (vi) be subject to voluntary prepayment as provided in Section 4.01, and mandatory repayment as provided in Section 4.02, and (vii) be entitled to the benefits of this Agreement and the other Credit
Documents.

(c) The German Term Note issued to each Lender that has a German Commitment or outstanding German Loans shall (i) be
executed by the German Borrower, (ii) be payable to such Lender or its registered assigns and be dated the Restatement Effective Date (or, if issued after the Restatement Effective Date, be dated the date of the issuance thereof), (iii) be
in a stated principal amount (expressed in Euros) equal to the principal amount of the German Loans of such Lender at such time and be payable in the outstanding principal amount of the German Loans evidenced thereby from time to time,
(iv) with respect to each German Loan evidenced thereby, be payable (subject to Section 2.14) in Euros, provided that the obligations with respect to each German Loan evidenced thereby shall be subject to conversion into

Section 2.08, (vii) be subject to voluntary prepayment as provided in Section 4.01, and mandatory repayment as provided in
Section 4.02, and (viii) be entitled to the benefits of this Agreement and the other Credit Documents.

(d) Each Lender
will note on its internal records the amount of each Loan made by it and each payment in respect thereof and prior to any transfer of any of its Notes will endorse on the reverse side thereof the outstanding principal amount of Loans evidenced
thereby. Failure to make any such notation or any error in such notation shall not affect any Borrowers obligations in respect of such Loans.

(e) Notwithstanding anything to the contrary contained above in this Section 2.05 or elsewhere in this Agreement, Notes shall only be delivered to Lenders which at any time specifically request the delivery of such Notes. No
failure of any Lender to request or obtain a Note evidencing its Loans to any Borrower shall affect or in any manner impair the obligations of the applicable Borrower to pay the Loans (and all related Term Obligations) incurred by such Borrower
which would otherwise be evidenced thereby in accordance with the requirements of this Agreement, and shall not in any way affect the security or guaranties therefor provided pursuant to the various Credit Documents. Any Lender which does not have a
Note evidencing its outstanding Loans shall in no event be required to make the notations otherwise described in preceding clause (d). At any time when any Lender requests the delivery of a Note to evidence any of its Loans, the applicable Borrower
shall promptly execute and deliver to the relevant Lender, at such Borrowers expense, the requested Note in the appropriate amount or amounts to evidence such Loans.

2.06 Conversions. Each Borrower shall have the option to convert, on any Business Day, all or a portion equal to at least the Minimum Borrowing
Amount of the outstanding principal amount of Dollar Denominated Loans made pursuant to one or more Borrowings (so long as of the same Tranche) of one or more Types of Dollar Denominated Loans into a Borrowing (of the same Tranche) of another Type
of Dollar Denominated Loan, provided that (i) except as otherwise provided in Section 2.10(b), Eurodollar Loans may be converted into Base Rate Loans only on the last day of an Interest Period applicable to the Loans being
converted and no such partial conversion of Eurodollar Loans shall reduce the outstanding principal amount of such Eurodollar Loans made pursuant to a single Borrowing to less than the Minimum Borrowing Amount applicable thereto, (ii) Loans
maintained as Base Rate Loans may not be converted into Eurodollar Loans if any Event of Default is in existence on the date of the conversion and the Administrative Agent, at the request of the Required Lenders, so notifies the relevant Borrower,
and (iii) no conversion pursuant to this Section 2.06 shall result in a greater number of Borrowings of Eurodollar Loans than is permitted under Section 2.02. Each such conversion shall be effected by the respective
Borrower by giving the Administrative Agent at the Notice Office prior to 2:00 p.m. (New York time) at least three Business Days prior notice (each a Notice of Conversion/Continuation) in the form of Exhibit A-2,
appropriately completed to specify the Loans to be so converted, the Borrowing or Borrowings pursuant to which such Loans were incurred and, if to be converted into Eurodollar Loans, the Interest Period to be initially applicable thereto. The
Administrative Agent shall give each Lender prompt notice of any such proposed conversion affecting any of its Loans. Upon any such conversion the proceeds thereof will be deemed to be applied directly on the day of such conversion to prepay the
outstanding principal amount of the Loans being converted.

2.07 Pro Rata Borrowings. All Borrowings of Loans under each Tranche shall be incurred from the
Lenders pro rata on the basis of their Commitments under such Tranche. It is understood that no Lender shall be responsible for any default by any other Lender of its obligation to make Loans hereunder and that each Lender shall be
obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder.

2.08 Interest. (a) The U.S. Borrower agrees to pay (in the case of U.S. Loans) and the German Borrower agrees to pay (in the case of a conversion of any German Loan into a Dollar Denominated Loan pursuant to
Section 2.14) interest in respect of the unpaid principal amount of each Base Rate Loan (including any German Loan converted into a Dollar Denominated Loan pursuant to Section 2.14) from the date of Borrowing thereof (or, in
the case of a conversion of any German Loan into a Dollar Denominated Loan pursuant to Section 2.14, from the date of the conversion of such Loan) until the earlier of (i) the maturity thereof (whether by acceleration or otherwise)
and (ii) the conversion of such Base Rate Loan to a Eurodollar Loan pursuant to Section 2.06 or 2.09, as applicable, at a rate per annum which shall be equal to the sum of the relevant Applicable Margin as in effect from time
to time plus the Base Rate as in effect from time to time.

(b) The U.S. Borrower agrees to pay (in the case of U.S. Loans) and the
German Borrower agrees to pay (in the case of German Loans) interest in respect of the unpaid principal amount of each Euro Rate Loan from the date of Borrowing thereof until the earlier of (i) the maturity thereof (whether by acceleration or
otherwise) and (ii) in the case of Eurodollar Loans, the conversion of such Eurodollar Loan to a Base Rate Loan pursuant to Section 2.06 or 2.09, as applicable, at a rate per annum which shall, during each Interest Period
applicable thereto, be equal to the sum of the relevant Applicable Margin as in effect from time to time during such Interest Period plus the relevant Euro Rate for such Interest Period plus in the case of Euro Denominated Loans, any
Mandatory Costs.

(c) To the extent permitted by law, overdue principal and overdue interest in respect of each Loan and any other overdue
amount payable hereunder and under any other Credit Document shall, in each case, bear interest at a rate per annum (1) in the case of overdue principal of, and interest or other overdue amounts owing with respect to, Euro Denominated Loans,
equal to 2% plus the Applicable Margin for Euro Rate Loans plus the relevant Euro Rate for such successive periods not exceeding one month as the Administrative Agent may determine from time to time in respect of amounts comparable to
the amount not paid plus any Mandatory Costs and (2) in all other cases, equal to the greater of (x) the rate which is 2% in excess of the rate then borne by such Loans and (y) the rate which is 2% in excess of the rate
otherwise applicable to Base Rate Loans of the respective Tranche of Loans from time to time. Interest that accrues under this Section 2.08(c) shall be payable on demand.

(d) Accrued (and theretofore unpaid) interest shall be payable (i) in respect of each Base Rate Loan, (x) quarterly in arrears on each
Quarterly Payment Date, (y) on the date of any repayment or prepayment in full of all outstanding Base Rate Loans of the respective Tranche of Loans being so repaid or prepaid, and (z) at maturity (whether by acceleration or otherwise)
and, after such maturity, on demand, and (ii) in respect of each Euro Rate Loan, (x) on the last day of each Interest Period applicable thereto and, in the case of an Interest Period



-60-



---

in excess of three months, on each date occurring at three month intervals after the first day of such Interest Period, (y) on the date of any repayment
or prepayment (on the amount repaid or prepaid), and (z) at maturity (whether by acceleration or otherwise) and, after such maturity, on demand.

(e) Upon each Interest Determination Date, the Administrative Agent shall determine the relevant Euro Rate for each Interest Period applicable to the relevant Euro Rate Loans and shall promptly notify Aleris and the
Lenders thereof. Each such determination shall, absent manifest error, be final and conclusive and binding on all parties hereto.

2.09
Interest Periods for Euro Rate Loans. At the time any Borrower gives any Notice of Borrowing or Notice of Conversion/Continuation in respect of the making of, or conversion into, any Euro Rate Loan (such notice shall be given (x) in the
case of the initial Interest Period applicable thereto or prior to 12:00 Noon, on the same date of the making of, or conversion into, such Euro Rate Loan, and (y) in the case of any subsequent Interest Period, no later than 12:00 noon (New York
time) on the third Business Day prior to the expiration of an Interest Period applicable to such Euro Rate Loan), such Borrower shall have the right to elect the Interest Period applicable to such Euro Rate Loan, which Interest Period shall, at the
option of such Borrower be a one, two, three or six month (or, if agreed by all Lenders with Commitments and/or Loans under the relevant Tranche, nine or twelve month) period, provided that (in each case):

(i) all Euro Rate Loans comprising a Borrowing shall at all times have the same Interest Period;

(ii) the initial Interest Period for any Euro Rate Loan shall commence on the date of Borrowing of such Euro Rate Loan (including the date
of any conversion thereto from a Base Rate Loan) and each Interest Period occurring thereafter in respect of such Euro Rate Loan shall commence on the day on which the next preceding Interest Period applicable thereto expires;

(iii) if any Interest Period for a Euro Rate Loan begins on a day for which there is no numerically corresponding day in the calendar
month at the end of such Interest Period, such Interest Period shall end on the last Business Day of such calendar month;

(iv) if any Interest Period for a Euro Rate Loan would otherwise expire on a day which is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided, however, that if any Interest
Period for a Euro Rate Loan would otherwise expire on a day which is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day;

(v) no Interest Period for any Borrowing of Eurodollar Loans may be selected at any time when any Event of Default is then
in existence and the Administrative Agent, at the request of the Required Lenders, has notified the relevant Borrower of same; and

(vi) no Interest Period in respect of any Borrowing of any Tranche of Euro Rate Loans shall be selected which extends beyond the Final Maturity Date.



-61-



---

If by 12:00 Noon (New York time) on the third Business Day prior to the expiration of any Interest Period
applicable to a Borrowing of Euro Rate Loans, any Borrower has failed to elect, or is not permitted to elect, a new Interest Period to be applicable to such Euro Rate Loans as provided above, such Borrower shall be deemed to have elected,
(x) if Eurodollar Loans to convert such Eurodollar Loans into Base Rate Loans and (y) if Euro Denominated Loans, to select a one-month Interest Period for such Euro Denominated Loans, in any case, effective as of the expiration date of
such current Interest Period.

Notwithstanding the foregoing, the German Borrower may split a Borrowing of German Loans into two or more
Borrowings at the end of the Interest Period applicable thereto and may combine Borrowings of German Loans (with Interest Periods ending on the same date) into a single Borrowing of a German Loan at the end of the Interest Period applicable thereto,
in each case by appropriate notice in the respective Notice of Conversion/Continuation and so long as the resultant Borrowings comply with all provisions of this Agreement (including Section 2.02).

2.10 Increased Costs, Illegality, etc. (a) In the event that any Lender shall have determined in good faith (which determination shall, absent
manifest error, be final and conclusive and binding upon all parties hereto but, with respect to clauses (i) and (iv) below, may be made only by the Administrative Agent):

(i) on any Interest Determination Date that, by reason of any changes arising after the Restatement Effective Date affecting the
applicable interbank market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of the relevant Euro Rate; or

(ii) at any time, that such Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect
to any Euro Rate Loan because of any change since the Restatement Effective Date in any applicable law or governmental rule, regulation, order, guideline or request (whether or not having the force of law) or in the interpretation or administration
thereof and including the introduction of any new law or governmental rule, regulation, order, guideline or request, such as, but not limited to (A) a change in the basis of taxation of payment to any Lender of the principal of or interest on
the Loans or the Notes or any other amounts payable hereunder (except for changes in taxes that are determined by reference to the net income or net profits or franchise taxes imposed in lieu thereof of such Lender or, in the case of a Lender that
is a flow-through entity for tax purposes, a member or a partner of such Lender, 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) and (B) a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of the relevant Euro Rate (provided
that increased costs or reductions in the amounts received or receivable with respect to Taxes shall be dealt with exclusively pursuant to Section 4.04); or

(iii) at any time, that the making or continuance of any Euro Rate Loan has been made (x) unlawful by any change since the
Restatement Effective Date in any



-62-



---

applicable law or governmental rule, regulation or order or (y) impossible by compliance by any Lender in good faith with any governmental request
(whether or not having force of law) made after the Restatement Effective Date; or

(iv) if applicable, at any time that
Euros are not available in sufficient amounts, as determined in good faith by the Administrative Agent, acting reasonably, to fund any Euro Denominated Loans 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 U.S. 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 the U.S. Borrower with respect to Eurodollar Loans which have
not yet been incurred (including by way of conversion) shall be deemed rescinded by such U.S. Borrower, and (B) in the event that any Euro Denominated Loan is so affected, Euro LIBOR shall be determined on the basis provided in the proviso to
the definition of Euro LIBOR, (x) in the case of clause (ii) above, the affected Borrower agrees 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 calculating, interest or otherwise as such Lender in its reasonable discretion shall determine) as shall be required to compensate such Lender for such increased costs or reductions in amounts received or receivable hereunder (a
written notice as to the additional amount or amounts owed to such Lender, showing in reasonable detail the basis for and the calculation thereof, submitted to the Borrower by such Lender shall, absent manifest error, be final and conclusive and
binding on all the parties hereto), (y) in the case of clause (iii) above, the affected Borrower 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, Euro Denominated Loans (exclusive of any such Euro Denominated Loans that have theretofore been funded), shall no longer be available until such time as the Administrative Agent
notifies the German 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 pursuant to Section 2.03 given by the respective German
Borrower with respect to such Euro Denominated Loans which have not been incurred shall be deemed rescinded by the German Borrower. 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 actually 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 affected by the circumstances described in Section 2.10(a)(iii), the affected Borrower shall, either (x) if the affected Euro Rate Loan is then being made initially or pursuant to a
conversion, cancel such Borrowing (or the conversion thereof) by giving the Administrative Agent



-63-



---

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 and (B) in the case of any Euro Denominated Loan, repay such affected Euro Denominated Loan in full in accordance with the applicable requirements of
Section 4.01; provided that, if the circumstances described in Section 2.10(a)(iii) apply to any Euro Denominated Loan, the Borrowers may, in lieu of taking the actions described above, maintain such Euro
Denominated Loan outstanding, in which case, Euro LIBOR shall be determined on the basis provided in the proviso to the definition of Euro LIBOR unless the maintenance of such Euro Denominated 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).

(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), will 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 reduction incurred more than 180 days prior to the date on which such Lender notifies such Borrower or Borrowers of the change in law described in
Section 2.10(a)(ii) or 2.10(c) giving rise to such increased costs or reduction 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,



-64-



---

expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its 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 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 pursuant to Section 4.01, Section 4.02 or as a result of an acceleration of the Loans pursuant to Section 9) or conversion of any of its Euro
Rate Loans occurs on a date which is not the last day of an Interest Period with respect thereto; (iii) if any prepayment of any of its Euro Rate Loans is not made on any date specified in a notice of prepayment given by any Borrower; or
(iv) as a consequence of (x) any other default by any Borrower to repay Euro Rate Loans when required by the terms of this Agreement or any Note 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.

2.12 Change of Lending Office. (a) Each Lender may at any time or from time to time designate, by written notice to the 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 by such Lender; 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 or 4.04 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 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) or Section 4.04 with respect to such Lender, it will, if requested by any Borrower, use reasonable efforts to designate
another lending office for any Loans 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 applicable 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 and 4.04.

2.13 Replacement of Lenders. (x) If any Lender becomes a Defaulting Lender or otherwise
defaults in its obligations to make Loans, (y) upon the occurrence of an event giving rise to the operation of Section 2.10(a)(ii) or (iii), Section 2.10(c) or Section 4.04 with respect to any Lender
which results in such Lender charging to any Borrower increased costs or (z) in the case of 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 11.12(d) but which require the consent of each Lender or each directly affected Lender, Aleris shall have the right either (A) to replace such Lender with one or more other Eligible
Transferees, none of whom shall constitute a Defaulting Lender at the time of such replacement (collectively, the Replacement Lender) and each of whom shall be reasonably acceptable to the Administrative Agent or (B) to
replace only (a) the Commitment (and sub-commitments and outstandings pursuant thereto) of the Replaced Lender with an identical Commitment provided by the Replacement Lender or (b) in the case of a replacement as provided in
Section 11.12(d) where the consent of the respective Lender is required with respect to less than all Tranches of its Loans or Commitments, the Commitments, sub-commitments and/or outstanding Loans of such Lender in respect of each
Tranche where the consent of such Lender would otherwise be individually required, with identical Commitments, sub-commitments and/or Loans of the applicable Tranche provided by the Replacement Lender (each such Lender which is replaced by a
Replacement Lender or whose Commitment (or any portion thereof) or Loans (or any portion thereof) is replaced (either pursuant to preceding clause (A) or (B)) is referred to herein as a Replaced Lender); provided that:

(i) at the time of any replacement pursuant to this Section 2.13, the Replacement Lender shall enter into one
or more Assignment and Assumption Agreements pursuant to Section 11.04(b) (and with all fees payable pursuant to said Section 11.04(b) to be paid by the Replacement Lender) pursuant to which the Replacement Lender shall
acquire all of the Commitments and all then outstanding Loans (or, in the case of the replacement of less than all the Tranches of Commitments and outstanding Loans of the relevant Replaced Lender, all the Commitments and/or all then outstanding
Loans relating to the Tranche or Tranches with respect to which such Lender is being replaced) of the Replaced Lender and, in connection therewith, shall pay to (w) the Replaced Lender in respect thereof an amount equal to the sum of
(A) an amount equal to (in the relevant currency or currencies) the aggregate principal of, and all accrued and unpaid interest on, all then outstanding Loans of the respective Replaced Lender under each Tranche with respect to which such
Replaced Lender is being replaced and (B) an amount equal to all accrued, but theretofore unpaid, Fees owing to the Replaced Lender (but only with respect to the relevant Tranche or Tranches, in the case of the replacement of less than all
Tranches then held by the relevant Replaced Lender) pursuant to Section 3.01; and

(ii) all obligations of the
Borrowers due and owing to the Replaced Lender at such time (other than those specifically described in clause (i) of this Section 2.13 in respect of which the assignment purchase price has been, or is concurrently being, paid)
shall be paid in full to such Replaced Lender concurrently with such replacement.

Upon receipt by the Replaced Lender of all amounts
required to be paid to it pursuant to this Section 2.13, the Administrative Agent shall be entitled (but not obligated) and



-66-



---

authorized to execute an Assignment and Assumption Agreement on behalf of such Replaced Lender, and any such Assignment and Assumption Agreement so executed
by the Administrative Agent and the Replacement Lender shall be effective for purposes of this Section 2.13 and Section 11.04. Upon the execution of the respective Assignment and Assumption Agreement, the payment of amounts
referred to in clauses (i) and (ii) of this Section 2.13, if so requested by the Replacement Lender, delivery to the Replacement Lender of the appropriate Note or Notes executed by the relevant Borrowers and the satisfaction of
the other applicable conditions in Section 11.04(b), the Replacement Lender shall become a Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder, except with respect to indemnification provisions under
this Agreement (including, without limitation, Sections 2.10, 2.11, 4.04, 11.06 and 11.01), which shall survive as to such Replaced Lender.

2.14 Special Provisions Applicable to Lenders Upon the Occurrence of a Conversion Event. On the date of the occurrence of a Conversion Event,
automatically (and without the taking of any action) (x) all then outstanding Euro Denominated Loans shall be automatically converted into Loans of the German Borrower (of the same Tranche) maintained in U.S. Dollars (in an amount equal to the
Dollar Equivalent of the aggregate principal amount of the respective Loans on the date such Conversion Event first occurred, which Loans (i) shall continue to be owed by the German Borrower and (ii) shall at all times thereafter be deemed
to be Base Rate Loans), and (y) all principal, accrued and unpaid interest and other amounts owing with respect to such Euro Denominated Loans shall be payable in U.S. Dollars, taking the Dollar Equivalent of such principal, accrued and
unpaid interest and other amounts. The occurrence of any conversion of Euro Denominated Loans to Base Rate Loans as provided above in this Section 2.14 shall be deemed to constitute, for purposes of Section 2.11, a prepayment
of Loans before the last day of any Interest Period relating thereto.

SECTION 3. Fees.

3.01 Fees. Each Borrower agrees to pay to the Administrative Agent such fees as may be agreed to in writing from time to time by Aleris or any of
its Subsidiaries and the Administrative Agent.

3.02 Commitments. Upon at least three 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), Aleris shall have the right, at any time or from time to time, without premium or penalty, to terminate the Total
Commitment in whole. Each reduction to the Total Commitment pursuant to this Section 3.02 shall apply to proportionately and permanently reduce the Commitment of each Lender (based on its respective Percentage).

3.03 Mandatory Reduction of Commitments. (a) The Total Commitment (i.e., the Total U.S. Commitment and the Total German Commitment)
shall terminate in its entirety on June 30, 2007, unless the Restatement Effective Date has occurred on or prior to such date.

(b) In
addition to any other mandatory commitment reductions pursuant to this Section 3.03, the Total Commitment (i.e., the Total U.S. Commitment and the Total German Commitment) shall terminate in its entirety on the Restatement
Effective Date (after giving effect to the incurrence of Loans on such date).

(c) Each reduction to, or termination of, the Total U.S. Commitment and the Total German Commitment
pursuant to this Section 3.03 as provided above shall be applied to proportionately reduce or terminate, as the case may be, the U.S. Commitment and the German Commitment, as the case may be, of each Lender with such a Commitment.

SECTION 4. Prepayments; Payments; Taxes.

4.01 Voluntary Prepayments. (a) Each Borrower shall have the right to prepay the Loans made to such Borrower, without premium or penalty, in whole or in part at any time and from time to time on the
following terms and conditions: (i) such Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) (x) prior to 10:00 a.m. (New York time) at the Notice Office on the date of such
prepayment in the case of Base Rate Loans and (y) prior to 12:00 noon (New York time) at the Notice Office at least three Business Days before the date of such prepayment of its intent to prepay Euro Rate Loans, which notice (in each case)
shall specify whether U.S. Loans or German 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 promptly transmit to each of the Lenders; (ii) each partial prepayment of Loans pursuant to this Section 4.01(a) shall be in an aggregate principal amount of at least
$1,000,000, in the case of U.S. Loans, and 1,000,000, in the case of German Loans (or, in each case, 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 German 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 German 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 German 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 4.01(a) in respect of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans; and (iv) each voluntary
prepayment of Loans pursuant to this Section 4.01(a) shall be applied to reduce the then remaining Scheduled Term Loan Repayments of the relevant Tranche in a manner to be determined by the relevant Borrower at the time that it delivers
a (and as specified in the applicable) notice of prepayment pursuant to this Section 4.01(a) (i.e., in direct order of maturity, in inverse order of maturity or pro rata based upon the then remaining principal amount of each such
Scheduled Term Loan Repayment after giving effect to all prior reductions thereto), although if the applicable Borrower fails to so specify the manner of application in any such notice, such voluntary prepayment shall be applied
(1) first, to reduce the Scheduled Term Loan Repayments (if any) with respect to the relevant Tranche which are due on the four Scheduled Term Loan Repayment Dates immediately



-68-



---

following the date of such prepayment and (2) second, to the extent in excess thereof to reduce the then remaining Scheduled Term Loan Repayments
of the relevant Tranche on a pro rata basis based upon the then remaining principal amount of each such Scheduled Term Loan Repayment of the relevant Tranche after giving effect to all prior reductions thereto.

(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 11.12(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 (x) the consents, if any, required under
Section 11.12(d) in connection with the repayment pursuant to this Section 4.01(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 11.12(d) to the extent applicable.

date set forth below (each, a Scheduled U.S. Term Loan Repayment Date), the U.S. Borrower shall be required to repay that principal amount of U.S. Loans, to the extent then outstanding, as is set forth opposite each such date

(g); provided, however, that so long as no Event of Default then exists, such Net Insurance Proceeds 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 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

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 4.02(d) without regard to the preceding

with this Section 4.02(f) shall be applied as a mandatory repayment of Loans, with each such repayment to be applied to U.S. Loans and German Loans on a pro rata basis, provided that if at the time of a repayment of the
Loans pursuant to Section 4.02(b), (c) or (d), the sum (the Sum) of (1) the Excess Availability under and as defined in the ABL Credit Agreement as in effect on the Restatement Effective Date
and (2) the cash and Cash Equivalents of Aleris and its Subsidiaries (other cash and Cash Equivalents which are Restricted or on deposit in an Exempted Deposit Account (as defined in the ABL Credit Agreement as in effect on the Restatement
Effective Date)) is less than $100,000,000, such repayment shall be applied first to the repayment of outstandings under the ABL Credit Agreement in such amount as may be required to cause the Sum to equal $100,000,000 and thereafter to the
repayment of the Loans as provided above, provided, further, that each amount required to be applied pursuant to Sections 4.02(c) and (d) shall (I) if sourced from Net Sale Proceeds or Net Insurance Proceeds
received by the U.S. Borrower or any of its Domestic Subsidiaries from the sale or condemnation of assets owned by the U.S. Borrower or any of its Subsidiaries, be applied (x) first, to repay principal of U.S. Loans until all U.S. Loans
are paid in full and (y) second, to repay principal of German Loans and (II) if sourced from Net Sale Proceeds or Net Insurance Proceeds received by the German Borrower or any of its Subsidiaries from the sale or condemnation of assets
owned by the German Borrower or any of its Domestic Subsidiaries, be applied (x) first, to repay principal of German Loans until all German Loans are paid in full and (y) second, to repay principal of U.S. Loans. The amount
of each principal repayment of Loans of any Tranche made as required by Sections 4.02(b), (c), (d) and (e) shall be applied to reduce the Scheduled Term Loan Repayments (if any) of the applicable Tranche in
direct order of their maturity.

(g) With respect to each repayment of Loans required by this Section 4.02, the applicable
Borrower or Borrowers may designate the Types of Loans of the applicable Tranche

which are to be repaid and, in the case of Euro Rate Loans, the specific Borrowing or Borrowings of the applicable Tranche pursuant to which such Euro Rate
Loans were made, provided that subject to Section 2.11 and clause (i) of this Section 4.02, each repayment of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans. In the
absence of a designation by the Borrowers as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its sole discretion.

(h) Notwithstanding anything in this Section 4.02 to the contrary, it is understood and agreed that none of Sections 4.02(a)
through (e), 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 Term Obligations owed by any U.S. Credit
Parties.

(i) Notwithstanding the foregoing provisions of this Section 4.02 (other than clause (a) of this
Section 4.02, which clause shall not have the benefits of this sentence), if at any time the mandatory repayment of Loans of a given Tranche pursuant to this Section 4.02 would result in the applicable Borrowers
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 thereto (any such Euro Rate Loans, Affected Loans), such Borrower 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 that any Affected Loans are otherwise required to be prepaid, the
applicable Borrower may elect to deposit 100% (or such lesser percentage elected by such Borrower as not being repaid) of the principal amounts that otherwise would have been paid in respect of such Affected Loans with the Administrative Agent to be
held as security for the obligations of the such Borrower 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 such Borrower from such cash collateral account (and applied to repay the principal amount of such Borrowers Euro Rate Loans) upon each occurrence
thereafter of the last day of an Interest Period applicable to the Euro Rate Loans of such Borrower (or such earlier date or dates as shall be requested by such Borrower, 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 (i) shall be on the applicable Borrower. 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.

4.03 Payments and Computations. 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 not later than 1:00 p.m. (New York time) on the date when due and shall be
made in (x) U.S. Dollars in immediately available funds at the Payment Office of the Administrative Agent in respect of any obligation of the Borrowers under this Agreement except as otherwise provided in the immediately following clause
(y) and (y) subject to Section 2.14, Euros in immediately available funds at the Payment Office of the Administrative Agent, if such payment is made in respect of (i) principal of or interest on Euro Denominated Loans or
(ii) any increased costs, indemnities or other amounts owing with respect to Euro 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 4.03 shall affect or alter the Borrowers obligations to the Administrative Agent, the Collateral Agent 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. Whenever any payment to be made hereunder or under any Note shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day
and, with respect to payments of principal, interest shall be payable at the applicable rate during such extension.

4.04 Net
Payments. (a) All payments made by or on behalf of any Credit Party under any Credit Document (including, in the case of the U.S. Borrower, in its capacity as a guarantor pursuant to Section 12) in each case will be made without
setoff, counterclaim or other defense. Except as provided in Section 4.04(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 4.04 Indemnitee such additional amounts as may be necessary so that every payment of all amounts due under this Agreement or under any other Credit Document, after withholding or deduction for or on account of any
Taxes, will not be less than the amount provided for herein or in such other Credit Document (including, for the avoidance of doubt, withholding and deductions applicable to additional amounts payable under this Section 4.04). The
respective Borrowers will furnish to the Administrative Agent as soon as practicable 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. Borrower and the German 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 4.04 Indemnitee and reimburse such Section 4.04 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 4.04 Indemnitee. Notwithstanding anything to the contrary in this Section 4.04(a), (i) any payments required to be made pursuant to this
Section 4.04(a) to an Indirect Section 4.04 Indemnitee shall be made to the Related Pass Through Entity and (ii) any request for reimbursement pursuant to this Section 4.04(a) that is to be made by an Indirect
Section 4.04 Indemnitee shall be made by the Related Pass Through Entity.

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. Borrower 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 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

Administrative Agent and/or such Lender shall immediately notify Aleris and the Administrative Agent of its inability to deliver any such form or Section 4.04(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 4.04(b)(ii) Certificate pursuant to this Section 4.04(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 4.04(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. Borrower 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

is required to do so by law, to deduct or withhold taxes imposed by the United States federal government (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 the U.S. 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 4.04(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 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 4.04(b) or (II) in the case of a payment, other than interest, to the Administrative Agent and/or a Lender (other than a
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. Notwithstanding anything to the

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 4.04(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 immediately preceding sentence 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 4.04(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, or Section 4.04(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

considerations of such Lender) to file any certificate or document or to furnish to the German Borrower any information, in each case, as reasonably requested by the German 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 4.04(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 4.04 to a Section 4.04 Indemnitee,
and such Section 4.04 Indemnitee determines in its reasonable 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 4.04 Indemnitee shall pay to such Borrower an amount (not to exceed
additional amounts paid by such Borrower under this Section 4.04 with respect to Taxes giving rise to such Tax Benefit) that the Section 4.04 Indemnitee shall, in its reasonable sole discretion, determine is equal to the net
benefit, after tax, which was obtained by such Section 4.04 Indemnitee in such year as a consequence of such Tax Benefit; provided, however, that (i) any Section 4.04 Indemnitee may determine, in its sole
discretion consistent with the policies of such Section 4.04 Indemnitee, whether to seek a Tax Benefit; (ii) any taxes that are imposed on a Section 4.04 Indemnitee as a result of a disallowance or reduction (including
through the expiration of any tax credit carryover or carryback of such Section 4.04 Indemnitee that otherwise would not have expired) of any Tax Benefit with respect to which such Section 4.04 Indemnitee has made a payment
to such Borrower pursuant to this Section 4.04(d) shall be treated as a Tax for which such Borrower is obligated to indemnify such Section 4.04 Indemnitee pursuant to this Section 4.04 without any exclusions or
defenses; (iii) nothing in this Section 4.04(d) shall require any Section 4.04 Indemnitee to disclose any confidential information to any Borrower (including, without limitation, its tax returns or its calculations); and
(iv) no Section 4.04 Indemnitee shall be required to pay any amounts pursuant to this Section 4.04(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 4.04 to a Section 4.04 Indemnitee, such Section 4.04 Indemnitee shall cooperate with such Borrower in challenging such Taxes, at such Borrowers expense, if so requested by such Borrower in writing.

SECTION 5. Conditions Precedent to Loans on the Restatement Effective Date. The obligation of each Lender to make Loans on the Restatement

substantially the form set forth as Exhibit O hereto (the Joinder Agreement). Upon execution and delivery thereof, each party to a Joinder Agreement (i) shall automatically become a Guarantor hereunder and thereupon

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

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 7.10(c).

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 Term 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 7.10, all at the expense of the Credit
Parties.

they are Immaterial Subsidiaries comprise in the aggregate more than 5.0% of Total Assets as of the end of the most recently ended Fiscal Quarter or more than 5.0% 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.

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 in this Agreement, 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;

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.

the case of a Subsidiary of the Swiss CE, to the Swiss CE or a Subsidiary thereof.

(c) Notwithstanding anything to the contrary contained
in this Agreement, Aleris shall not, and shall not permit any Restricted Subsidiary to, cause, make or suffer to exist (i) the sale, conveyance, transfer or other disposition, whether in a single transaction or a series of related transactions,

failure by Aleris or any Subsidiary of Aleris to make such a Special Mandatory Redemption shall not constitute an Event of Default to the extent that such requirement and/or failure does not constitute an event of default under the New Senior Note
Indenture or any other Material Indebtedness; or

9.05 Bankruptcy, etc. (a) An involuntary proceeding shall be commenced or an
involuntary petition shall be filed seeking (i) liquidation, reorganization or other relief in respect of any Borrower or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) or its

9.07 Guaranties. Any Guaranty of any Significant Subsidiary (or any group of Subsidiaries that
together would constitute a Significant Subsidiary) or Aleris shall for any reason cease to be in full force and effect or be declared null and void or any Responsible Officer of any Guarantor that is a Significant Subsidiary (or the Responsible
Officers of any group of Subsidiaries that together would constitute a Significant Subsidiary) or Aleris, as the case may be, denies that it has any further liability under its Guaranty or gives notice to such effect, other than by reason of the
termination of this Agreement or the release of any such Guaranty in accordance with this Agreement; or

9.08 Security Documents.
After the execution and delivery thereof, unless all of the Collateral has been released from the Liens in accordance with the provisions of the Security Documents, any Security Document shall for any reason cease to be in full force and effect or

9.10 Change of Control. A Change of Control shall occur;

then, and in any such event, and at any time thereafter, if any Event of Default shall then be continuing, the Administrative Agent, upon the written request of the Required Lenders, shall by written notice to Aleris, take any or all of the
following actions, without prejudice to the rights of the Administrative Agent, any Lender or the holder of any Note to enforce its claims against any Credit Party (provided that, if an Event of Default specified in Section 9.05
shall occur with respect to any Borrower, the result which would occur upon the giving of written notice by the Administrative Agent as specified in clauses (i) and (ii) below shall occur automatically without the giving of any such
notice): (i) declare the Total Commitment terminated, whereupon all Commitments of each Lender shall forthwith terminate immediately; (ii) declare the principal of and any accrued interest in respect of all Loans and the Notes evidencing
such Loans and all other Term Obligations owing with respect thereto hereunder and thereunder to be, whereupon the same shall become, forthwith due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby
waived by each Credit Party; and (iii) enforce, as Collateral Agent, all of the Liens and security interests created pursuant to the Security Documents securing Term Obligations owing to the Lenders.

In the event of any Event of Default specified in Section 9.04, such Event of Default and all consequences thereof (excluding any resulting payment default)
shall be annulled, waived and rescinded automatically and without any action by the Administrative Agent or the Lenders if, within 20 days after such Event of Default arose, (i) the Indebtedness or guarantee that is the basis for such Event of
Default has been discharged, (ii) the holders thereof have rescinded or



-128-



---

waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (iii) the default that is the basis for such
Event of Default has been cured.

Solely for the purposes of determining whether an Event of Default has occurred under Section 9.04, any
reference in any such paragraph to any Subsidiary shall be deemed not to include any Immaterial Subsidiary affected by any event or circumstance referred to in such Section; provided that if it is necessary to exclude more than one Subsidiary
from Section 9.04 pursuant to this paragraph in order to avoid an Event of Default thereunder, all excluded Subsidiaries shall be considered to be a single consolidated Subsidiary for purposes of determining whether the condition
specified above is satisfied.

SECTION 10. The Administrative Agent and Collateral Agent.

10.01 Appointment. The Lenders hereby irrevocably designate and appoint DBNY as Administrative Agent (for purposes of this Section 10
and Section 11.01 (and all guarantees of obligations pursuant to said Sections, and for purposes of the Security Documents), the term Administrative Agent will include DBNY (and any successor Collateral Agent or
Collateral Agents)) in its capacity as Collateral Agent pursuant to the Security Documents. Each Lender hereby irrevocably authorizes, and each holder of any Note by the acceptance of such Note shall be deemed irrevocably to authorize, the
Administrative Agent to take such action on its behalf under the provisions of this Agreement, the other 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 agreed, for avoidance of doubt and without limiting the generality of the foregoing, that the Administrative Agent shall be permitted to
designate one of its affiliates to perform the duties to be performed by the Administrative Agent hereunder with respect to Loans and Letters of Credit denominated in Euros and the provisions of this Section 10 shall apply to any such
affiliate mutatis mutandis).

10.02 Nature of Duties. (a) The Administrative Agent shall have no duties or
responsibilities except those expressly set forth in this Agreement and in the other Credit Documents. Neither the Administrative Agent nor any of its officers, directors, agents, employees or affiliates shall be liable for any action taken or
omitted by them hereunder or under any other Credit Document or in connection herewith or therewith, unless caused by their gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable
decision). The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Lender or
the holder of any Note; and nothing in this Agreement or in any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other
Credit Document except as expressly set forth herein or therein.

(b) Notwithstanding any other provision of this Agreement or any
provision of any other Credit Document, the Syndication Agent, the Co-Documentation Agents, the Joint



-129-



---

Lead Arrangers and the Joint Book Running Managers are named as such for recognition purposes only, and in their respective capacities as such shall have no
powers, duties, responsibilities or liabilities with respect to this Agreement or the other Credit Documents or the transactions contemplated hereby and thereby; it being understood and agreed that the Syndication Agent, the Co-Documentation Agents,
the Joint Lead Arrangers and the Joint Book Running Managers shall each be entitled to all indemnification and reimbursement rights in favor of the Administrative Agent (to the same extent as provided for the Administrative Agent) as, and to the
extent, provided for under Sections 10.06 and 11.01 (which provisions shall be deemed incorporated by reference herein). Without limitation of the foregoing, neither the Syndication Agent, the Co-Documentation Agents, the Joint Lead
Arrangers nor the Joint Book Running Managers shall, solely by reason of this Agreement or any other Credit Documents, have any fiduciary relationship in respect of any Lender or any other Person.

10.03 Lack of Reliance on the Administrative Agent. Independently and without reliance upon the Administrative Agent, each Lender and the holder
of each Note, to the extent it deems appropriate, has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of Aleris and its Subsidiaries in connection with the making and the continuance
of the Loans and the taking or not taking of any action in connection herewith and (ii) its own appraisal of the creditworthiness of Aleris and its Subsidiaries and, except as expressly provided in this Agreement, the Administrative Agent shall
not have any duty or responsibility, either initially or on a continuing basis, to provide any Lender or the holder of any Note with any credit or other information with respect thereto, whether coming into its possession before the making of the
Loans or at any time or times thereafter. The Administrative Agent shall not be 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, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency of this Agreement or any other Credit Document or the financial condition
of Aleris or any of its Subsidiaries or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any other Credit Document, or the financial condition of
Aleris or any of its Subsidiaries or the existence or possible existence of any Default or Event of Default.

10.04 Certain Rights of
the Administrative Agent. If the Administrative Agent requests instructions from the Required Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any other Credit Document, the Administrative
Agent shall be entitled to refrain from such act or taking such action unless and until the Administrative Agent shall have received instructions from the Required Lenders; and the Administrative Agent shall not incur liability to any Lender by
reason of so refraining. Without limiting the foregoing, neither any Lender nor the holder of any Note shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from
acting hereunder or under any other Credit Document in accordance with the instructions of the Required Lenders.

10.05 Reliance.
The Administrative Agent shall be entitled to rely, and 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



-130-



---

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.

10.06 Indemnification. To the extent the Administrative Agent (or any affiliate thereof) is not reimbursed and indemnified by the Borrowers, the Lenders will reimburse and indemnify the Administrative Agent
(and any affiliate thereof) in proportion to their respective percentage as used in determining the Required Lenders (determined as if there were no Defaulting Lenders) for and against any and all liabilities, obligations, losses,
damages, penalties, claims, actions, judgments, costs, expenses or disbursements of whatsoever kind or nature which may be imposed on, asserted against or incurred by the Administrative Agent (or any affiliate thereof) in performing its duties
hereunder or under any other Credit Document (including, without limitation, any account control agreements entered into pursuant to any Security Agreement) or in any way relating to or arising out of this Agreement or any other Credit Document
(including, without limitation, any account control agreements entered into pursuant to any Security Agreement); provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, claims,
actions, judgments, suits, costs, expenses or disbursements resulting from the 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).

10.07 The Administrative Agent in its Individual Capacity. With respect to its obligation to make Loans
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 respective 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.

10.08 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. 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.

10.09 Resignation by the Administrative Agent. (a) The Administrative Agent may resign from
the performance of all its respective 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 9.05 then exists, Aleris. Such resignation shall take effect upon the appointment of a successor 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 or Collateral Agent, as applicable, hereunder or thereunder who shall be a commercial bank or trust company reasonably acceptable to Aleris, which acceptance shall not 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 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 10.09, the Administrative Agent shall remain indemnified to the
extent provided in this Agreement and the other Credit Documents and the provisions of this Section 10 shall continue in effect for the benefit of such Administrative Agent for all of its actions and inactions while serving as the
Administrative Agent.

10.10 Collateral Matters. (a) Each Lender authorizes and directs the Collateral Agent to enter into the
Security Documents for the benefit of the Lenders and the other Secured Creditors. Each Lender hereby agrees, and each holder of any Note by the acceptance thereof will be deemed to agree, that, except as otherwise set forth herein, any action taken
by the Required Lenders in accordance with the provisions of this Agreement or the Security Documents, and the exercise by the Lenders (or any authorized sub-group thereof) of the powers set forth herein or therein, together with such other powers
as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders. The Collateral Agent is hereby authorized on behalf of all of the Lenders, without the necessity of any notice to or further consent from any Lender, from
time to time prior to an Event of Default, to take any action with respect to any Collateral or Security Documents which may be necessary to perfect and maintain



-132-

perfected the security interest in and liens upon the Collateral granted pursuant to 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 Term 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 8.06, (iii) upon the request of the Borrowers, so long as the fair market
value of any Collateral released in any Fiscal Year pursuant to this Section 10.10(b)(iii) does not exceed $5,000,000, (iv) if approved, authorized or ratified in writing by the Required Lenders (or all of the Lenders hereunder, to
the extent required by Section 11.12), (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 obligations under its Guaranty in accordance with the terms of this Agreement. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Collateral Agents authority to release
particular types or items of Collateral pursuant to this Section 10.10(b).

(c) The Collateral Agent shall have no obligation
whatsoever to the Lenders or 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 10.10 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.

(e) Each Lender authorizes and directs the Collateral Agent and the Administrative Agent to enter into the
intercreditor agreements and related documents in respect of (i) Secured Hedging Agreements and (ii) Other Pari Passu Lien Obligations.

all interests in Term Obligations purchased by such Lender pursuant to Section 11.06(b), and all other claims of any nature or description arising out of or connected with this Agreement or any other Credit Document, irrespective of
whether or not the Administrative Agent or such Lender shall have made any demand hereunder and although said Term Obligations, liabilities or claims, or any of them, shall be contingent or unmatured, provided, however, that none of

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 11.04 (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
obligations under this Agreement, (D) the participant shall not constitute a Lender hereunder, (E) any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain
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 Loans 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 all or substantially all of the
Collateral under all of the Security Documents (except as expressly provided in the Credit Documents) supporting the Loans hereunder in which such participant is participating. In the case of any such participation, the participant shall not have
any rights under this Agreement or any of the other Credit Documents (the participants rights against such Lender in respect of such participation to be those set forth in the 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, provided, further that 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 4.04) 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 or 4.04 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 4.04 unless the relevant Borrower is



-137-



---

notified of the participation sold to such participant and such participant agrees, for the benefit of such Borrower, to comply with Section 4.04 as
though it were a Lender.

(b) Subject to clause (c) below, any Lender (or any Lender together with one or more other Lenders) may
(x) assign all or a portion of its outstanding Term 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 $1,000,000 (taking the Dollar
Equivalent of any amounts denominated in Euros), in each case in the aggregate for the assigning Lender or assigning Lenders of such outstanding Term 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) at such time, Schedule I shall be deemed modified to reflect the outstanding Loans, as the case may be, of such new Lender and of the existing Lenders, (ii) 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 outstanding Loans, as the case may be, (iii) 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), (iv) the consent of the Administrative Agent shall be required in connection with any assignment
pursuant to clause (y) above (which consent shall not be unreasonably withheld or delayed), (v) 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, (vi) no such transfer or assignment will be effective until recorded by the Administrative Agent on the Register pursuant to Section 11.15 and (vii) unless a Significant Event of Default
with respect to Aleris has occurred and is continuing, no Lender may assign its Loans to a Disqualified Lender. To the extent of any assignment pursuant to this Section 11.04(b), the assigning Lender shall be relieved of its obligations
hereunder with respect to its assigned outstanding Loans. At the time of each assignment pursuant to this Section 11.04(b) to a Person which is not already a Lender hereunder (other than a German Lender solely in its capacity as a Lender
to the German Borrower), 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 4.04(b)(ii)
Certificate) described in Section 4.04(b). To the extent that prior to the occurrence of a Conversion Event (but not with respect to assignments effected thereafter) an assignment of all or any portion of a Lenders outstanding Term
Obligations pursuant to Section



-138-



---

2.13 or this Section 11.04(b) would, at the time of such assignment, result in amounts payable under Section 2.10 or
4.04 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 or 4.04 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 11.04 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 11.04(a).

(c) Nothing in this Agreement shall prevent or prohibit any Lender from pledging its Loans and Notes hereunder to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank and,
with prior notification to the Administrative Agent (but without the consent of the Administrative Agent or Aleris), any Lender which is a fund may pledge all or any portion of its Loans and Notes to its trustee or to a collateral agent providing
credit or credit support to such Lender in support of its obligations to such trustee, such collateral agent or a holder of such obligations, as the case may be. No pledge pursuant to this clause (c) shall release the transferor Lender from any
of its obligations hereunder or substitute any such pledgee for such Lender as a party hereto.

11.05 No Waiver; Remedies
Cumulative. No failure or delay on the part of the Administrative Agent, the Collateral Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between any Borrower or
any other Credit Party and the Administrative Agent, the Collateral Agent or any Lender shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document
preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights, powers and remedies herein or in any other Credit Document expressly provided are cumulative and not exclusive
of any rights, powers or remedies which the Administrative Agent, the Collateral Agent or any Lender would otherwise have. No notice to or demand on any Credit Party in any case shall entitle any Credit Party to any other or further notice or demand
in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent, the Collateral Agent or any Lender to any other or further action in any circumstances without notice or demand.

11.06 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 Term 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



-139-



---

respective shares, if any, of the Term 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
exercise of the right of setoff or bankers lien, by counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise), which is applicable to the payment of the principal of, or interest on, the Loans, 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 Term Obligation then owed and due to such Lender bears to the total of such Term 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 Term 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 11.06(a) and (b) shall be subject to the express provisions of this Agreement which require, or permit, differing payments to be made to Non-Defaulting Lenders as opposed
to Defaulting Lenders.

11.07 Calculations; Computations. (a) The financial statements to be furnished to the Lenders pursuant
hereto shall be made and prepared in accordance with GAAP consistently applied throughout the periods involved (except as set forth in the notes thereto or as otherwise disclosed in writing by Aleris to the Lenders); provided that (i) if
at any time any change in GAAP would affect the computation of any financial ratio or requirement set forth in any Credit Document, and either Aleris or the Required Lenders shall 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.

(b) All computations of interest and other Fees hereunder shall be made
on the basis of a year of 360 days (or in the case of Base Rate Loans (and other amounts owing hereunder or under any other Credit Document to which the Base Rate is applicable) 365 or 366 days, as the case may be) for the actual number of days
(including the first day but excluding the last day) occurring in the period for which such interest or Fees are payable.

CITY ON THE TERMS AND FOR THE PURPOSES OF THIS PROVISION REASONABLY SATISFACTORY TO THE ADMINISTRATIVE AGENT UNDER THIS AGREEMENT. EACH BORROWER HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH COURTS LACK PERSONAL JURISDICTION OVER ANY

11.09 Counterparts.
This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same
instrument. A set of counterparts executed by all the parties hereto shall be lodged with Aleris and the Administrative Agent.

11.10
Effectiveness. This Agreement (as amended and restated) shall become effective on the date (the Restatement Effective Date) on which (i) each Borrower, the Administrative Agent, each Lender (which shall include the
Required Lenders (determined immediately before the occurrence of the Restatement Effective Date and without giving effect thereto)) shall have signed a counterpart hereof (whether the same or different counterparts) and shall have delivered the
same (including by way of facsimile transmission) to the Administrative Agent at the Notice Office (or, in the case of the Lenders, shall have given to the Administrative Agent telephonic (confirmed in writing), written or telex notice (actually
received) at such Notice Office that the same has been signed and mailed to it); it being understood that any Existing Lender which does not execute a counterpart hereof shall be replaced in accordance with the provisions of
Section 11.12(d) and (ii) the conditions contained in Section 5 are met to the reasonable satisfaction of the Administrative Agent. Unless the Administrative Agent has received actual notice from any Lender that the
conditions contained in Section 5 have not been met to its satisfaction, upon the satisfaction of the condition described in clause (i) of the immediately preceding sentence and upon the Administrative Agents good faith
determination that the conditions described in clause (ii) of the immediately preceding sentence have been met, then the Restatement Effective Date shall have been deemed to have occurred, regardless of any subsequent determination that one or
more of the conditions thereto had not been met (although the occurrence of the Restatement Effective Date shall not release the Borrowers from any liability for failure to satisfy one or more of the applicable conditions contained in
Section 5). The Administrative Agent will give each Lender prompt written notice of the occurrence of the Restatement Effective Date.

11.11 Headings Descriptive. The headings of the several sections and subsections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

11.12 Amendment or Waiver; etc. (a) Neither this Agreement nor any other Credit Document nor any
terms hereof or thereof may be changed or waived unless such change or waiver is in writing signed by the respective Credit Parties party hereto or thereto and the Required Lenders (although additional parties may be added to (and annexes may be
modified to reflect such additions), and Subsidiaries of Aleris may be released from this Agreement, the Guaranties and the Security Documents in accordance with the provisions hereof and thereof without the consent of the other Credit Parties party
thereto or the Required Lenders), provided that no such change or waiver, shall, without the consent of each Lender (other than a Defaulting Lender) (with Term Obligations being directly affected in the case of following clause (i)),
(i) extend or postpone the final scheduled maturity or any date fixed for any scheduled repayment of principal of any Loan or Note or extend the duration of any Interest Period for a Euro Rate Loan beyond six months, or reduce the rate or
extend the time of payment of interest or Fees thereon (except in connection with the waiver of applicability of any post-default increase in interest rates), or reduce the principal amount thereof, (ii) release all or substantially all of the
Collateral (except as expressly provided in the Credit Documents) under all the Security Documents, (iii) amend, modify or waive any provision of this Section 11.12(a) (except for technical amendments with respect to additional
extensions of credit pursuant to this Agreement which afford the protections to such additional extensions of credit of the type provided to the Commitments on the Restatement Effective Date), (iv) reduce the percentage specified in the
definition of Required Lenders (it being understood that, with the consent of the Required Lenders, additional extensions of credit pursuant to this Agreement may be included in the determination of the Required Lenders on substantially the same
basis as the extensions of Commitments are included on the Restatement Effective Date), or (v) consent to the assignment or transfer by any Borrower of any of its rights and obligations under this Agreement; provided further, that
no such change or waiver shall (1) increase the Commitments of any Lender over the amount thereof then in effect without the consent of such Lender (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 an increase of the Commitment of any Lender, and that an increase in the available portion of any Commitment of any Lender shall
not constitute an increase of the Commitment of such Lender), (2) without the consent of the Administrative Agent, amend, modify or waive any provision of Section 10 or any other provision of this Agreement as same relates to the
rights or obligations of the Administrative Agent, (3) without the consent of the Collateral Agent, amend, modify or waive any provision relating to the rights or obligations of the Collateral Agent, (4) without the consent of the
Syndication Agent, the Co-Documentation Agents or the Joint Lead Arrangers, amend, modify or waive any provision relating to the rights or obligations of the Syndication Agent, the Co-Documentation Agents or the Joint Lead Arrangers, as the case may
be, or (5) 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 for technical amendments
with respect to additional extensions of credit pursuant to this Agreement which afford the protections to such additional extensions of credit of the type provided to the Commitments on the Restatement Effective Date).

(b) Notwithstanding anything to the contrary in this Section 11.12, (i) a Guarantor shall automatically be released from its obligations
hereunder and its Guaranty shall be automatically released upon the consummation of any transaction permitted hereunder as a result of which such Guarantor ceases to be a Subsidiary of Aleris and (ii) so long as no Event of



-143-



---

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 such release of the Guarantor would not result in any Immaterial Subsidiary being required pursuant to Section 7.10(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 7.10(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 8.04(d), 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 upon receipt of such officers certificate from Aleris. In connection with any such release, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantors expense, all
documents that such Guarantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this Section 11.12(b) shall be without recourse to or warranty
by the Administrative Agent.

(c) Notwithstanding anything to the contrary in this Section 11.12, 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 11.12(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) 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, to replace
only the respective Tranche of Loans of the respective non-consenting Lender which gave 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) repay each Tranche of outstanding Loans of such Lender which gives rise to the need to obtain such Lenders consent, in accordance with
Section 4.01(b), provided that, unless the Loans that are repaid pursuant to preceding clause (B) are immediately replaced in full at such time through the addition of new Lenders or outstanding Loans of existing Lenders (who
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 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 11.12(a).

11.13 Survival. All indemnities set forth herein including, without limitation, in Sections
2.10, 2.11, 4.04, 10.06 and 11.01 shall survive the execution, delivery and termination of this Agreement and the Notes and the making and repayment of the Term Obligations.

11.14 Domicile of Loans. Each Lender may transfer and carry its Loans 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 pursuant to this Section 11.14 would, at the time of such transfer, result in amounts payable under Section 2.10,
2.11 or 4.04 that exceed the amounts that 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).

11.15 Register. Each Borrower hereby designates the Administrative Agent to serve as its agent, solely for
purposes of this Section 11.15, 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 11.04(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 11.15.

11.16 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 that such Persons shall be subject to the provisions of this Section 11.16 to the same extent as such Lender) any information with respect to the Transaction, the



-145-



---

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 11.16(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 subpoena or in connection with any litigation, (iv) in order to comply with any law, order, regulation or ruling applicable to such Lender, (v) to the Administrative Agent or the Collateral Agent, (vi) to any direct or indirect
contractual counterparty in any swap, hedge or similar agreement (or to any such contractual counterpartys professional advisor), so long as such contractual counterparty (or such professional advisor) agrees to be bound by the provisions of
this Section 11.16, and (vii) to any pledgee under Section 11.04(c) 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 11.16. Any
person required to maintain the confidentiality of information as provided in this Section 11.16 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 11.16 to the same extent as such Lender.

11.17 INTERCREDITOR

11.19 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, all 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, Germany, Canada, Switzerland, Belgium, France and England and any 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 11.19, all such actions shall be taken in accordance with the provisions of this Section 11.19 and Section 7.10 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 Interests and promissory notes issued by, Persons organized under laws of jurisdictions other than the United States, Germany, Canada, Switzerland, Belgium, France and England and any State, province or territory
thereof) not required to be taken in accordance with the provisions of this Section 11.19, 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 7.10 and this
Section 11.19.

11.20 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



-148-



---

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 XI as promptly as practicable, and in any event within the time periods set forth in Schedule XI. The provisions of Schedule XI 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 11.20 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 11.20 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 11.20 will be, or have been, taken within the relevant time periods referred to in this Section 11.20 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 11.20, 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.

11.21 The PATRIOT Act. Each Lender subject to 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.

11.22 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



-149-



---

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 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 of 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.

11.23 Pledges of Bank Accounts Under General Terms and Conditions. Security created by any general terms and conditions of business of a Secured Creditor over LTIBR owing to a Credit Party shall not secure
directly or indirectly any loans made to any German Borrowing Party (other than the relevant Credit Party itself) under the Credit Documents, but will nonetheless be valid as security for all other obligations secured under such general terms and
conditions of business.

11.24 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 11.24, 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.



-150-



---

(d) Any amount due and payable by a Borrower to the Collateral Agent under this Section 11.24
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 11.24;
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 11.24.

(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.

11.25 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 11.25 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



-151-



---

be administered in accordance with this Agreement and the Credit Documents. 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 applicable 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.

11.26 Absence of Back-to-Back Financing. (a) For the purposes of providing
evidence to the German tax authorities of the absence of any detrimental recourse situation in connection with the tax guidelines issued by the German Federal Ministry of Finance (Bundesfinanzministerium) on 15 July 2004 (IV A2 
S2742a  20/04) and on 22 July 2005 (IV B7  S2742a  31/05) (together, the Decree) in relation to section 8a of the German Corporation Tax Act (Körperschaftssteuergesetz), the Collateral Agent
agrees subject to compliance by the Borrowers with the provisions of clauses (b) and (e) below, to deliver on behalf of each Lender to Aleris acting in this respect as recipient on behalf of each German Borrowing Party no later than 40
Business Days after (i) the Restatement Effective Date, (ii) each accession of a German Borrowing Party to this Agreement as a Borrower and (iii) no later than 40 Business Days after any amendment to this Agreement or any Security

(Bundesministerium der Finanzen) on 20 October 2005 (the Sample). For purposes of enabling the Collateral Agent to issue the Bank Certificate on behalf of each Lender, Aleris will provide the Collateral Agent with a
list of guarantees, Security Documents and restrictions as required in the Sample on (x) the Restatement Effective Date, (y) the date of accession of a German Borrowing Party and (z) the date of any amendment to this Agreement or any
Security Document as set out in clause (iii) above.

(b) Each Borrower undertakes to inform the Collateral Agent without undue delay
if it becomes aware of any incorrectness or incompleteness of a Bank Certificate given or to be given from time to time by the Collateral Agent pursuant to paragraph a) above.

(c) The delivery of a Bank Certificate shall not prejudice the rights of the Collateral Agent or the Lenders under this Agreement or any other Credit
Document. In the event of any inconsistencies between the terms of a Bank Certificate and the terms of an individual Security Document, the terms of the relevant Security Document shall prevail. A Bank Certificate shall under no circumstances
constitute a waiver or release of any Security Document.

(d) Each Borrower confirms to the Collateral Agent and each Lender that:

(i) each Bank Certificate is given by the Collateral Agent for the purpose of delivery to the competent tax authorities of
the German Borrowing Parties to assist the



-152-



---

German Borrowing Parties in the administration of their tax affairs and not for any other purpose,

(ii) the Collateral Agent and the Lenders are not responsible for examining the Credit Parties tax position and that the Bank

(iv) no Bank Certificate creates third party rights of any kind.

(e) It is the common understanding of the parties that no party

(f) Any costs and expenses incurred by the Collateral Agent or any Lender in connection with the provision of a Bank Certificate will be borne by the Borrowers. Neither the Collateral Agent nor any Lender shall be liable as a result of the
delivery of a Bank Certificate. Each Borrower agrees to indemnify the Collateral Agent and each Lender with respect to any potential claims that might be made against the Collateral Agent or any Lender with respect to any Bank Certificate by any
third party, the Borrowers being in this case jointly and severally liable to the Collateral Agent and each Lender for such indemnification. No Borrower will raise any claims against the Collateral Agent or any Lender based on, or in connection
with, a (correct/complete or incorrect/incomplete) Bank Certificate.

(g) For the avoidance of doubt:

(i) None of the Collateral Agent nor any Lender shall be obliged to disclose to any other person any confidential information regarding

-153-



---

(i) the Collateral Agent agrees to deliver to Aleris such updated Bank Certificate; or

(ii) the Lenders agree to issue such Bank Certificate.

Each Borrower releases the Collateral Agent from its general obligation to maintain confidentiality in connection with the requirements of this Section 11.

SECTION 12.
U.S. Borrower Guaranty.

12.01 Guaranty. In order to induce the Administrative Agent, the Collateral Agent, 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 and Other Hedging Agreements and in recognition of the direct benefits to be received by the
U.S. Borrower from the proceeds of the German Loans and the entering into of such Interest Rate Protection Agreements and Other Hedging Agreements, the U.S. Borrower hereby agrees with the Guaranteed Creditors as follows: the U.S. Borrower hereby
unconditionally and irrevocably guarantees the full and prompt payment when due, whether upon maturity, acceleration or otherwise, of any and all of the Relevant Term Loan Guaranteed Obligations to the Guaranteed Creditors. If any or all of the
Relevant Term Loan Guaranteed Obligations to the Guaranteed Creditors becomes due and payable hereunder, the U.S. Borrower, unconditionally and irrevocably, promises to pay such indebtedness to the Administrative Agent and/or the other Guaranteed

12.02 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 Term Loan 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 the U.S. Borrower agrees that any such judgment,
decree, order, settlement or compromise shall be binding upon the U.S. Borrower, notwithstanding any revocation of this U.S. Borrower Guaranty or other instrument evidencing any liability of any Guaranteed Party, and the U.S. Borrower shall be and
remain liable to the



-154-



---

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.

12.03 Bankruptcy. Additionally, the U.S. Borrower unconditionally and irrevocably guarantees the payment of any and all of the
Relevant Term Loan Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by the German Borrower upon the occurrence of any of the events specified in Section 9.05, and irrevocably and unconditionally promises
to pay such indebtedness to the Guaranteed Creditors, or order, on demand, in lawful money of the United States.

12.04 Nature of
Liability. The liability of the U.S. Borrower hereunder is primary, absolute and unconditional, exclusive and independent of any security for or other guaranty of the Relevant Term Loan Guaranteed Obligations, whether executed by any other
guarantor or by any other party, and the liability of the 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 Term Loan 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 Term Loan 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 the 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 12.06, or (g) any invalidity, irregularity or enforceability of all or any part of the Relevant Term Loan
Guaranteed Obligations or of any security therefor.

12.05 Independent Obligation. The obligations of the 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 the 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. The 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 the U.S. Borrower.

12.06 Authorization. The 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 Term Loan 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



-155-



---

incurred directly or indirectly in respect thereof, and this U.S. Borrower Guaranty shall apply to the Relevant Term Loan Guaranteed Obligations as so
changed, extended, renewed or altered;

(b) take and hold security for the payment of the Relevant Term Loan 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 Term Loan
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;

(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 Term Loan 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 any 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, 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 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 the U.S. Borrower from its liabilities under this U.S. Borrower Guaranty.

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

12.08 Waiver. (a) The 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. The U.S. Borrower waives any defense based on or arising out of any defense of any Guaranteed Party,



-156-



---

any other guarantor or any other party, other than payment of the Relevant Term Loan Guaranteed Obligations to the extent of such payment, based on or
arising out of the disability of any Guaranteed Party, the U.S. Borrower, any other guarantor or any other party, or the validity, legality or unenforceability of the Relevant Term Loan 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 Term Loan 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 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 the U.S. Borrower hereunder except
to the extent the Relevant Term Loan Guaranteed Obligations have been paid. The 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 the U.S. Borrower against any Guaranteed Party or any other party or any security.

(b) The 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 Term Loan Guaranteed Obligations. The U.S. Borrower assumes all responsibility for being and keeping itself informed of any Guaranteed Partys financial
condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Relevant Term Loan Guaranteed Obligations and the nature, scope and extent of the risks which the 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 the U.S. Borrower of information known to them regarding such circumstances or risks.

(c) The U.S. Borrower hereby acknowledges and affirms that it understands that to the extent any Relevant Term Loan Guaranteed Obligations are secured by
Real Property located in the State of California, the Guaranteeing Party 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 the German
Borrowers or any Guaranteed Creditors right to proceed against the U.S. Borrower or any other guarantor of the Relevant Term Loan Guaranteed Obligations.

(d) The 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. The 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 the 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
Term Loan Guaranteed Obligations have been paid in full in cash, the U.S. Borrower waives its rights of subrogation and reimbursement and any other

rights and defenses available to the U.S. Borrower by reason of Sections 2787 to 2855, inclusive, of the California Civil Code, including, without
limitation, (1) any defenses the 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 the U.S. Borrower may have by reason of protection
afforded to the German Borrower pursuant to the antideficiency or other laws of California limiting or discharging the German Borrowers indebtedness, including, without limitation, Sections 580a, 580b, 580d and 726 of the California Code of
Civil Procedure. In furtherance of such provisions, the 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 remedies, such as a nonjudicial foreclosure
destroys the U.S. Borrowers rights of subrogation and reimbursement against the German Borrower by the operation of Section 580d of the California Code of Civil Procedure or otherwise.

(f) The 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.

12.09 Maximum Liability. It is the desire and intent of the U.S. Borrower and the Guaranteed Creditors that this U.S. Borrower Guaranty shall be
enforced against the 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 the 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 the U.S.
Borrowers obligations under this U.S. Borrower Guaranty shall be deemed to be reduced and the U.S. Borrower shall pay the maximum amount of the Relevant Term Loan Guaranteed Obligations which would be permissible under applicable law.

SECTION 13. Limitation on German 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 German Borrower, the European Parent Guarantors or 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 Term Obligation of any 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 13 to the extent possible, and where such other provisions conflict with the provisions of this
Section 13, the provisions of this Section 13 shall govern.
