shall not exceed in aggregate principal amount at any time outstanding the relevant Maximum Swingline Amount. 
 Notwithstanding anything to
the contrary contained in this Section 2.01(c), (i) no Swingline Lender shall be obligated to make any Swingline Loans at a time when a Lender Default exists with respect to a Lender unless such Swingline Lender has entered into
arrangements satisfactory to it and the U.S. Borrowers, the European Borrower and/or Canadian Borrowers, as applicable, to eliminate such Swingline Lender’s risk with respect to the Defaulting Lender’s or Defaulting Lenders’
participation in such Swingline Loans, including by cash collateralizing such Defaulting Lender’s or Defaulting Lenders’ U.S./European Percentage (in the case of U.S./European Borrower Swingline Loans) or Canadian Percentage (in the case
of Canadian Swingline Loans) of the outstanding Swingline Loans, and (ii) no Swingline Lender shall make any Swingline Loan after such Swingline Lender has received written notice from the Borrowers, any other Credit Party or the Required
Lenders stating that a Default or an Event of Default exists and is continuing until such time as such Swingline Lender shall have received written notice (A) of rescission of all such notices from the party or parties originally delivering
such notice or notices or (B) of the waiver of such Default or Event of Default by the Required Lenders. 
 (d) On any Business Day,
either Swingline Lender may, in its sole discretion, give notice to the Lenders under the relevant Tranche (i.e., the U.S./European Lenders in the case of the U.S./European Borrower Swingline Loans and the Canadian Lenders in the case of the
Canadian Swingline Loans) that such Swingline Lender’s outstanding Swingline Loans shall be funded with one or more Borrowings of Revolving Loans under the relevant Tranche (provided that such notice shall be deemed to have been
automatically given upon the occurrence of a Default or an Event of Default under Section 11.05 or upon the exercise of any of the remedies provided in the last paragraph of Section 11), in which case one or more Borrowings
of Revolving Loans constituting Base Rate Loans, in the case of Swingline Loans maintained in U.S. Dollars, Euro Rate Loans subject to an Interest Period of one month, in the case of Swingline Loans maintained in a currency other than U.S. Dollars
or Canadian Dollars, or Canadian Prime Rate Loans, in the case of Canadian Swingline Loans maintained in Canadian Dollars, (each such Borrowing, a “Mandatory Borrowing”) shall be made on the immediately succeeding Business Day (or,
in the case of a Mandatory Borrowing of Euro Rate Loans, the second succeeding Business Day) by all Lenders pro rata based on each such Lender’s Facility Percentage under the relevant Tranche (determined before giving effect to
any termination of the 

  

 -69- 








 
Commitments pursuant to the last paragraph of Section 11) and the proceeds thereof shall be applied directly by such Swingline Lender to repay
such Swingline Lender for such outstanding Swingline Loans. Each Lender with a Commitment under the relevant Tranche hereby irrevocably agrees to make Revolving Loans under the relevant Tranche upon one Business Day’s notice (or, in the case of
a Mandatory Borrowing of Euro Rate Loans, two Business Days’ notice) pursuant to each Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the date specified in writing by the relevant Swingline Lender
notwithstanding (i) the amount of the Mandatory Borrowing may not comply with the Minimum Borrowing Amount otherwise required hereunder, (ii) whether any conditions specified in Section 7 are then satisfied, (iii) whether
a Default or an Event of Default then exists, (iv) the date of such Mandatory Borrowing, and (v) the amount of any Borrowing Base or Commitment at such time. In the event that any Mandatory Borrowing cannot for any reason be made on the
date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code or any other relevant bankruptcy or insolvency laws with respect to any Borrower), then each Lender with a
Commitment under the relevant Tranche hereby agrees that it shall forthwith purchase (as of the date the Mandatory Facility Borrowing would otherwise have occurred, but adjusted for any payments received from the relevant Borrowers on or after such
date and prior to such purchase) from the relevant Swingline Lender such participations in the outstanding Swingline Loans of such Swingline Lender as shall be necessary to cause the Lenders with Commitments under the relevant Tranche to share in
such relevant Swingline Loans ratably based upon their respective Percentages (determined before giving effect to any termination of the Commitments pursuant to the last paragraph of Section 11), provided that (x) all
interest payable on such Swingline Loans shall be for the account of such Swingline Lender until the date as of which the respective participation is required to be purchased and, to the extent attributable to the purchased participation, shall be
payable to the participant from and after such date and (y) at the time any purchase of participations pursuant to this sentence is actually made, the purchasing Lender shall be required to pay the relevant Swingline Lender interest on the
principal amount of participation purchased for each day from and including the day upon which the Mandatory Borrowing would otherwise have occurred to but excluding the date of payment for such participation, at the overnight Federal Funds Rate for
the first three days and at the interest rate otherwise applicable to Revolving Loans maintained as Base Rate Loans (or, in the case of Non-Dollar Denominated Loans, the interest rate that is applicable to the respective Mandatory Borrowing)
hereunder for each day thereafter. 
 (e) Notwithstanding anything to the contrary in Sections 2.01(a), (b), (c) or
(d), Section 7.03 or elsewhere in this Agreement, the Administrative Agent and the Collateral Agent shall have the right to establish reserves in such amounts, and with respect to such matters, as the Administrative Agent or the
Collateral Agent in its respective Permitted Discretion shall deem necessary or appropriate, against any Borrowing Base, including, without limitation, reserves with respect to (i) sums that the respective Borrowers are or will be required to
pay (such as Priority Payables, taxes, priority claims of employees, assessments, insurance premiums, or, in the case of leased assets, rents or other amounts payable under such leases) and have not yet paid (including, without limitation, an Unpaid
Supplier Reserve and a Rent Reserve against Eligible Inventory included in any Borrowing Base), (ii) Hedge Product Reserves and Bank Product Reserves, (iii) Insolvency Administrator Reserves and (iv) amounts owing by the respective
Borrowers or their respective Subsidiaries to any Person to the extent secured by a Lien on, or trust over, any of the Collateral, which Lien or trust, in the Permitted Discretion of 

  

 -70- 








 
the Administrative Agent or the Collateral Agent is capable of ranking senior in priority to or pari passu with one or more of the Liens
granted in the Security Documents (such as Priority Payables or other Liens or trusts in favor of employees, landlords, warehousemen, carriers, mechanics, materialmen, laborers, or suppliers, or Liens or trusts for ad valorem, excise,
sales, or other taxes where given priority under applicable law) in and to such item of the Collateral, provided, however, that the Administrative Agent may not implement reserves with respect to matters which are already specifically
reflected as ineligible Accounts or Inventory. 
 (f) In the event any of the U.S. Borrowers, the Canadian Borrowers or the European Borrower
is unable to comply with the conditions precedent to the making of Revolving Loans or the issuance of Letters of Credit set forth in Section 7 (including, without limitation, the Borrowing Base limitations set forth in
Section 7.03), (x) the U.S./European Lenders authorize the Administrative Agent, for the account of the U.S./European Lenders, to make U.S. Borrower Revolving Loans to the U.S. Borrowers and (y) the Canadian Lenders authorize
the Canadian Administrative Agent, for the account of the Canadian Lenders, to make Canadian Revolving Loans to the Canadian Borrowers (each, an “Agent Advance”), which, in each case, (i) may only be made in U.S. Dollars as
Base Rate Loans and (ii) may be made at any time or from time to time on or after the date the Administrative Agent first receives a Notice of Borrowing requesting an Agent Advance until the earlier of (A) the 30th Business Day after such
date, (B) the date the respective Borrowers or Borrower are again able to comply with the Borrowing Base limitations and the conditions precedent to the making of Revolving Loans and issuance of Letters of Credit, or obtains an amendment or
waiver with respect thereto or (C) the date the Required Lenders instruct the Administrative Agent and the Canadian Administrative Agent to cease making Agent Advances (in each case, the “Agent Advance Period”). Neither the
Administrative Agent nor the Canadian Administrative Agent shall make any Agent Advance to the extent that at such time the amount of such Agent Advance (A) in the case of Agent Advances made to the Canadian Borrowers, (I) when added to
the aggregate outstanding amount of all other Agent Advances made to the Canadian Borrowers and the U.S. Borrowers at such time, would exceed 5% of the Combined U.S./Canadian Borrowing Base at such time (based on the Borrowing Base Certificate last
delivered) less the European U.S. Borrowing Base Usage at such time or (II) when added to the Aggregate Canadian Exposure as then in effect (immediately prior to the incurrence of such Agent Advance), would exceed the Total Canadian Commitment at
such time, or (B) in the case of Agent Advances made to the U.S. Borrowers, (I) when added to the aggregate outstanding amount of all other Agent Advances made to the U.S. Borrowers at such time, would exceed 5% of the U.S. Borrowing Base
at such time (based on the Borrowing Base Certificate last delivered) less the Aggregate Non-U.S. Borrowing Base Usage at such time, (II) when added to the aggregate outstanding amount of all other Agent Advances made to the U.S. Borrowers and the
Canadian Borrowers at such time, would exceed 5% of the Combined U.S./Canadian Borrowing Base at such time (based on the Borrowing Base Certificate last delivered) less the European U.S. Borrowing Base Usage at such time or (III) when added to the
Aggregate U.S./European Exposure at such time (immediately prior to the incurrence of such Agent Advance), would exceed the Total U.S./European Commitment at such time. It is understood and agreed that, subject to the requirements set forth above,
Agent Advances may be made by the Administrative Agent or the Canadian Administrative Agent in the case of Canadian Borrower Obligations in their respective discretion to the extent the Administrative Agent or the Canadian Administrative Agent deems
such Agent Advances necessary or desirable (x) to preserve and protect the applicable Collateral, or any portion thereof, (y) to enhance the 

  

 -71- 








 
likelihood of, or maximize the amount of, repayment of the Revolving Loans and other obligations of the Credit Parties hereunder and under the other Credit
Documents or (z) to pay any other amount chargeable to or required to be paid by the Borrowers pursuant to the terms of this Agreement, including payments of reimbursable expenses and other sums payable under the Credit Documents, and that the
Borrowers shall have no right to require that any Agent Advances be made. Agent Advances will be deemed U.S./European Borrower Swingline Loans (if made to the U.S. Borrowers) or Canadian Swingline Loans (if made to the Canadian Borrowers) for all
purposes of this Agreement and shall be subject to refunding as a Mandatory Borrowing pursuant to Section 2.01(d), in each case, notwithstanding (i) after giving effect thereto, the relevant Maximum Swingline Amount may be exceeded
and (ii) the other conditions set forth in Sections 2.01(c) or (d), as applicable may not be satisfied at such time. 
 2.02 Minimum Amount of Each Borrowing; Limitation on Euro Rate Loans. (a) The aggregate principal amount of each Borrowing of Loans under a respective Tranche of Loans shall not be less than the Minimum Borrowing Amount
applicable to such Tranche of Loans. More than one Borrowing may occur on the same date, but at no time shall there be outstanding more than (x) 15 Borrowings of Euro Rate Loans in the aggregate for all Tranches of Loans and (y) more than
5 Borrowings of Bankers’ Acceptance Loans. 
 (b) Unless the Administrative Agent and the Syndication Agent either otherwise agree in
their sole discretion or have determined that the Syndication Date has occurred, prior to the 30th day following the Initial Borrowing Date (at which time this clause Section 2.02(b) shall no longer be applicable), (i) U.S./European
Revolving Loans and Canadian Revolving Loans may only be incurred and maintained as, and/or converted into, Euro Rate Loans so long as all such outstanding Euro Rate Loans, together with all other outstanding Revolving Loans that are maintained as
Euro Rate Loans, are subject to an Interest Period of one month which begins and ends on the same day and (ii) Canadian Revolving Loans may only be incurred and maintained as, and/or converted into, Bankers’ Acceptance Loans only so long
as such outstanding Bankers’ Acceptance Loans have a term to maturity of 30 days. 
 2.03 Notice of Borrowing. (a) Whenever
a Borrower desires to incur (x) Euro Rate Loans (excluding Borrowings of Swingline Loans and Mandatory Borrowings) or Bankers’ Acceptance Loans hereunder, such Borrower shall give the Administrative Agent at the Notice Office no later than
2:00 P.M. (New York time) at least three Business Days’ prior notice of each Euro Rate Loan or Bankers’ Acceptance Loan to be incurred hereunder, (y) Base Rate Loans hereunder (excluding Borrowings of Swingline Loans and Mandatory

(z) Canadian Prime Rate Loans hereunder (excluding Borrowings of Swingline Loans and Mandatory Borrowings), such Borrower shall give the Administrative Agent at the Notice Office no later than 12:00 Noon (New York time) at least one Business
Day’s prior notice of each Canadian Prime Rate Loan is to be incurred hereunder. Each such notice (each, a “Notice of Borrowing”), except as otherwise expressly provided in Section 2.10, shall be irrevocable and
shall be in writing, or by telephone promptly confirmed in writing, in the form of Exhibit A-1, appropriately completed to specify: (i) the aggregate principal amount or Face Amount, as the case may be, of the Loans to be made pursuant
to such Borrowing (stated in the applicable Available Currency), (ii) the date of such Borrowing (which shall be a Business 

  

 -72- 








 
Day), (iii) whether the respective Borrowing shall consist of U.S. Borrower Revolving Loans, Canadian Revolving Loans or European Borrower Revolving
Loans, (iv) in the case of Dollar Denominated Loans, whether the Dollar Denominated Loans being made pursuant to such Borrowing are to be initially maintained as Base Rate Loans or Eurodollar Loans and, if Eurodollar Loans, the Interest Period
to be initially applicable thereto, (v) in the case of Euro Denominated Loans and Other Foreign Currency Denominated Loans, the Interest Period to be initially applicable thereto, and (vi) in the case of Canadian Dollar Denominated Loans,
whether the respective Borrowing shall consist of Canadian Prime Rate Loans or Bankers’ Acceptance Loans and, if Bankers’ Acceptance Loans, the term thereof (which shall comply with the requirements of Schedule III). The
Administrative Agent shall promptly give each Lender which is required to make Loans of the Tranche specified in the respective Notice of Borrowing, notice of such proposed Borrowing, of such Lender’s proportionate share thereof and of the
other matters required by the immediately preceding sentence to be specified in the Notice of Borrowing. 
 (b) (i) Whenever a Borrower
desires to make a Borrowing of (x) U.S. Borrower Swingline Loans or Canadian Swingline Loans hereunder, such Borrower shall give the relevant Swingline Lender, not later than 1:00 P.M. (New York time) on the date such relevant Swingline Loan is
to be made or (y) European Borrower Swingline Loans hereunder, such Borrower shall give the U.S./European Swingline Lender, not later than 1:00 P.M. (New York time) one Business Day prior to the date such European Borrower Swingline Loan is to
be made, written notice or telephonic notice promptly confirmed in writing of each Swingline Loan to be made hereunder. Each such notice shall be irrevocable and shall be given by or on behalf of the respective Borrower in the form of Exhibit
A-1, appropriately completed to specify: (A) the date of Borrowing (which shall be a Business Day), (B) the aggregate principal amount of the Swingline Loans to be made pursuant to such Borrowing and (C) in the case of Canadian
Swingline Loans or European Borrower Swingline Loans, the relevant Available Currency in which such Swingline Loans are to be denominated. 
 (ii) Mandatory Borrowings shall be made upon the notice specified in Section 2.01(d), with the U.S. Borrowers or Canadian Borrowers, as applicable, irrevocably agreeing, by its incurrence of any Swingline Loan, to the making of
the Mandatory Borrowings as set forth in Section 2.01(d). 
 (c) Without in any way limiting the obligation of any Borrower to
confirm in writing any telephonic notice of any Borrowing or prepayment of Loans, the relevant Administrative Agent or the relevant Swingline Lender (in the case of a Borrowing of Swingline Loans) may act without liability upon the basis of
telephonic notice of such Borrowing or prepayment, as the case may be, believed by the relevant Administrative Agent or such Swingline Lender, as the case, may be, in good faith to be from the president, the chief executive officer or a Financial
Officer of such Borrower, or from any other authorized officer of such Borrower designated in writing by such Borrower to the relevant Administrative Agent or the Swingline Lender, as the case may be, as being authorized to give such notices, prior
to receipt of written confirmation. In each such case, such Borrower hereby waives the right to dispute the relevant Administrative Agent’s or the Swingline Lender’s, as the case may be, record of the terms of such telephonic notice of
such Borrowing or prepayment of Loans, as the case may be, absent manifest error.

not later than 10:00 A.M. (New York time) on the date specified in Section 2.01(d) and (z) in the case of a Borrowing of Euro Denominated Loans and Other Foreign Currency Denominated Loans, no later than 1:00 P.M.] (New York time),
on such date), each Lender with a Commitment under the relevant Tranche of Loans will, subject to Section 16, make available its pro rata portion (determined in accordance with Section 2.07) of each such
Borrowing requested to be made on such date (or, in the case of Swingline Loans, the respective Swingline Lender shall make available the full amount thereof). All such amounts will be made available in the relevant Available Currency, and in
immediately available funds at the Payment Office, and the relevant Administrative Agent will make available to the respective Borrower or Borrowers (or to the relevant Swingline Lender, in the case of a Mandatory Borrowing at the Payment Office the
aggregate of the amounts so made available by the Lenders. Unless the relevant Administrative Agent shall have been notified by any Lender prior to the date of Borrowing that such Lender does not intend to make available to the relevant
Administrative Agent such Lender’s portion of any Borrowing to be made on such date (other than in the circumstances described in Section 16), the relevant Administrative Agent may assume that such Lender has made such amount
available to the relevant Administrative Agent on such date of Borrowing and the relevant Administrative Agent may (but shall not be obligated to), in reliance upon such assumption, make available to the relevant Borrower or Borrowers a
corresponding amount. If such corresponding amount is not in fact made available to the relevant Administrative Agent by such Lender, the relevant Administrative Agent shall be entitled to recover such corresponding amount on demand from such
Lender. If such Lender does not pay such corresponding amount forthwith upon the relevant Administrative Agent’s demand therefor, the relevant Administrative Agent shall promptly notify the relevant Borrower or Borrowers and such Borrower or
Borrowers shall immediately pay such corresponding amount to the relevant Administrative Agent. The relevant Administrative Agent also shall be entitled to recover on demand from such Lender or the relevant Borrower or Borrowers, as the case may be,
interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the relevant Administrative Agent to such Borrower or Borrowers until the date such corresponding amount is recovered by the
relevant Administrative Agent, at a rate per annum equal to (i) if recovered from such Lender, the overnight Federal Funds Rate (or (x) in the case of Canadian Dollar Denominated Loans, the cost to the Canadian Administrative Agent of
acquiring overnight funds in Canadian Dollars, (y) in the case of Euro Denominated Loans, the cost to the relevant Administrative Agent of acquiring overnight funds in Euros or (z) in the case of Other Foreign Currency Denominated Loans,
the cost to the relevant Administrative Agent of acquiring overnight funds in the applicable Available Currency in which such Other Foreign Currency Denominated Loans were incurred) for the first three days and at the interest rate otherwise
applicable to such Loans for each day thereafter, and (ii) if recovered from the relevant Borrower or Borrowers, the rate of interest applicable to the respective Borrowing, as determined pursuant to Section 2.08. Nothing in this
Section 2.04 shall be deemed to relieve any Lender from its obligation to make Loans hereunder or to prejudice any rights which any Borrower may have against any Lender as a result of any failure by such Lender to make Loans hereunder;
provided that the funding of all U.S./European

issuance thereof, the European Borrower Swingline Note of the U.S./European Swingline Lender would not be at least as great as the outstanding principal amount (taking the Dollar Equivalent of all European Borrower Swingline Loans evidenced thereby)
of the European Borrower Swingline Loans made by the U.S./European Swingline Lender at any time outstanding, the U.S./European Swingline Lender may request (and in such case the European Borrower shall promptly execute and deliver) a new European
Borrower Swingline Note in an amount equal to the aggregate principal amount (taking the Dollar Equivalent of all European Borrower Swingline Loans evidenced thereby) of the European Borrower Swingline Loans of the U.S./European Swingline Lender
outstanding on the date of the issuance of such new European Borrower Swingline Note, (iv) mature on the Swingline Expiry Date, (v) bear interest as provided in the appropriate clause of Section 2.08, (vi) be subject to
voluntary prepayment as provided in Section 5.01 and mandatory repayment as provided in Section 5.02 and (vii) be entitled to the benefits of this Agreement and the other Credit Documents. 
 (h) 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. 
 (i) 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 respective Borrower to pay the Loans (and all related ABL 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 (h). At any
time when any Lender requests the delivery of a Note to evidence any of its Loans, the respective Borrower shall promptly execute and deliver to the respective Lender, at such Borrower’s expense, the requested Note in the appropriate amount or
amounts to evidence such Loans.

 2.06 Conversions. (a) Subject to Section 2.02(b), 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 (other than Swingline Loans, which shall at all times be maintained as Base Rate
Loans or Canadian Prime Rate Loans, as the case may be) 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) unless the Required
Lenders otherwise agree, Revolving Loans maintained as Base Rate Loans may only be converted into Eurodollar Loans if no Significant Event of Default or, if elected by the Required Lenders or the Administrative Agent, any other Event of Default is
in existence on the date of the conversion, and (iii) no conversion pursuant to this Section 2.06(a) 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. 
 (b) Mandatory
and voluntary conversions of Bankers’ Acceptance Loans into Canadian Prime Rate Loans shall be made in the circumstances, and to the extent, provided in Schedule III. Except as otherwise provided under Section 2.14,

 (c) The Canadian Borrowers shall have the option to convert, on any Business Day occurring on or after the Initial Borrowing Date, all or a portion at
least equal to the applicable Minimum Borrowing Amount of the outstanding principal amount of Canadian Prime Rate Loans (other than Swingline Loans, which shall at all times be maintained as Base Rate Loans or Canadian Prime Rate Loans, as the case
may be) made pursuant to one or more Borrowings under a single Tranche into a Borrowing or Borrowings of Bankers’ Acceptance Loans under such Tranche; provided that (i) unless the Required Lenders otherwise agree, Canadian Prime
Rate Loans may not be converted into Bankers’ Acceptance Loans if a Significant Event of Default or, if elected by the Required Lenders or the Canadian Administrative Agent, any other Event of Default is in existence on the date of such
conversion and (ii) Borrowings of Bankers’ Acceptance Loans resulting from this Section 2.06 shall be limited in number as provided in Section 2.02. Each such conversion shall be effected by the Canadian Borrowers
by giving the Canadian Administrative Agent at its Notice Office, prior to 11:00 A.M.(New York time), at least three Business Days prior to the date of the proposed conversion, a Notice of Conversion/Continuation specifying the Canadian Dollar
Denominated 

  

 -79- 








 
Loans to be so converted into Bankers’ Acceptance Loans, the Borrowing or Borrowings pursuant to which such Canadian Dollar Denominated Loans were made
and the term of the proposed Borrowing of Bankers’ Acceptance Loans (which, in each case, shall comply with the requirements of Schedule III). The Canadian Administrative Agent shall give each Canadian Lender prompt notice of any such
proposed conversion affecting any of its Canadian Revolving Loans maintained as Canadian Prime Rate 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 Canadian Revolving Loans being converted. 
 2.07 Pro Rata Borrowings. All Borrowings of Revolving Loans of a
given Tranche under this Agreement shall be incurred from the Lenders pro rata on the basis of their Facility Percentages under such Tranche. All Borrowings of U.S./European Borrower Swingline Loans shall be incurred from the
U.S./European Swingline Lender. All Borrowings of Canadian Swingline Loans shall be incurred from the Canadian Swingline Lender. 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. Borrowers (jointly and severally) agree to pay (in the case of U.S. Borrower Revolving Loans and U.S. Borrower
Swingline Loans), the Canadian Borrowers agree to pay (in the case of Canadian Revolving Loans and Canadian Swingline Loans) and the European Borrower agrees to pay (in the case of a conversion of any European Borrower Revolving Loan which is a
Non-Dollar Denominated 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 Canadian Dollar Denominated Loan made to the Canadian Borrowers
and 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 Non-Dollar Denominated 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. Borrowers (jointly and severally) agree to pay (in the case of U.S. Borrower Revolving Loans), the Canadian Borrowers (jointly and
severally) agree to pay (in the case of Canadian Revolving Loans) and the European Borrower agrees to pay (in the case of European Borrower Revolving Loans and European Borrower Swingline 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 Non-Dollar Denominated Euro Rate Loans, any Mandatory Costs. 
 (c) The Canadian Borrowers (jointly and severally) agree to pay (in the case of Canadian Revolving Loans and Canadian Swingline Loans, in each case, which are Canadian 

  

 -80- 








 
Dollar Denominated Loans) interest in respect of the unpaid principal amount of each Canadian Prime Rate Loan made to it from the date the proceeds thereof
are made available to it (which shall, in the case of a conversion contemplated by Schedule III, be deemed to be the date upon which a maturing Bankers’ Acceptance or B/A Equivalent Note is converted into a Canadian Prime Rate Loan
pursuant to said Schedule III, with the proceeds thereof to be equal to the full Face Amount of such maturing Bankers’ Acceptance or B/A Equivalent Note), until the earlier of (i) the maturity thereof (whether by acceleration, or
otherwise) and (ii) the conversion of such Canadian Prime Rate Loan to a Bankers’ Acceptance Loan pursuant to Section 2.06, at a rate per annum which shall be equal to the sum of the Canadian Prime Rate in effect from time to
time during the period such Canadian Prime Rate Loan is outstanding plus the relevant Applicable Margin as in effect from time to time. 
 (d) 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

Canadian Prime Rate, each as in effect from time to time, (2) in the case of overdue principal of, and interest or other overdue amounts owing with respect to, Non-Dollar Denominated Euro Rate Loans, equal to 2% plus the Applicable
Margin for Euro Rate Loans as in effect from time to time 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 (3) 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(d) shall be payable on demand. 
 (e) Accrued (and theretofore unpaid) interest shall be payable (i) in respect of each Base Rate Loan and Canadian Prime Rate Loan (including,
without limitation, Swingline Loans), (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 or Canadian Prime Rate Loans, as the case may be, 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 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. 
 (f)
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 

  

 -81- 








 
conversion into, any Euro Rate Loan (in the case of the initial Interest Period applicable thereto) or prior to 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 (in the case of any subsequent Interest Period), 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 (but otherwise subject to Section 2.02(b)) 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) unless the Required Lenders
otherwise agree, no Interest Period for any Borrowing of Eurodollar Loans may be selected at any time when a Significant Event of Default (or, if elected by the Required Lenders or the Administrative Agent any other Event of Default) is then in
existence; 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. 
 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 Non-Dollar Denominated Euro Rate Loans, to select a one-month Interest Period for such Non-Dollar Denominated Euro Rate Loans, in any case,
effective as of the expiration date of such current Interest Period. 
 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 

  

 -82- 








 
conclusive and binding upon all parties hereto but, with respect to clause (i) below, may be made only by the Administrative Agent or the Canadian
Administrative Agent, as applicable): 
 (i) on any Interest Determination Date that, by reason of any changes arising after
the date of this Agreement 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 (x) any change since the 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 the rate of tax on, or 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) or (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
and/or (y) other circumstances arising since the Effective Date affecting the applicable interbank market; or 
 (iii) at
any time, that the making or continuance of any Euro Rate Loan has been made (x) unlawful by any law or governmental rule, regulation or order, (y) impossible by compliance by any Lender in good faith with any governmental request (whether
or not having force of law) or (z) impracticable as a result of a contingency occurring after the Effective Date which materially and adversely affects the interbank Eurodollar market; or 
 (iv) at any time there is no market for Bankers’ Acceptances by reason of circumstances affecting the Canadian money market generally
or the relevant Available Currency (other than U.S. Dollars) is not available in sufficient amounts, as determined in good faith by the Administrative Agent, acting reasonably, to fund any Borrowing of Bankers’ Acceptance Loans, Non-Dollar
Denominated Loans, as the case may be, requested pursuant to Section 2.01; 
 then, and in any such event, such Lender (or the Administrative
Agent, in the case of clauses (i) or (iv) above) shall promptly give notice (by telephone promptly confirmed in writing) to the affected Borrower and, except in the case of clauses (i) and (iv) above, to the Administrative Agent
of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (w) in the case of clause (i) above, (A) in the event Eurodollar Loans are so affected, Eurodollar Loans
shall no longer be available until such time as the Administrative Agent notifies the affected Borrower and the Lenders that the 

  

 -83- 








 
circumstances giving rise to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing or Notice of Conversion/Continuation given
by any Borrower with respect to Eurodollar Loans which have not yet been incurred (including by way of conversion) shall be deemed rescinded by such Borrower, and (B) in the event that any Non-Dollar Denominated Rate Loan is so affected, the
relevant Euro Rate shall be determined on the basis provided in the proviso to the definition for the relevant Euro Rate, (x) in the case of clause (ii) above, the Borrowers agree to pay to such Lender, upon such Lender’s written
request therefor, such additional amounts (in the form of an increased rate of, or a different method of 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 amounts owed to such Lender, showing in reasonable detail the basis for and the calculation thereof, submitted to the Borrowers
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 respective Borrower or Borrowers shall take one of the actions specified in
Section 2.10(b) as promptly as possible and, in any event, within the time period required by law and (z) in the case of clause (iv) above, Bankers’ Acceptance Loans or Loans in the relevant Available Currency, as
applicable (exclusive of any such Loans, which have theretofore been funded), shall no longer be available until such time as the Administrative Agent notifies the respective Borrower or Borrowers and the Lenders that the circumstances giving rise
to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing or notice pursuant to Section 2.03 given by the respective Borrower or Borrowers with respect to such Loans which have not been incurred shall be
deemed rescinded by such Borrower or Borrowers. Each of the Administrative Agent and each Lender agrees that if it gives notice to any Borrower of any of the events described in clause (i), (ii), (iii) or (iv) above, it shall promptly
notify such Borrower and, in the case of any such Lender, the Administrative Agent, promptly after it 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) or (iii), 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 by giving the Administrative
Agent telephonic notice (confirmed in writing) on the same date that 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 Non-Dollar Denominated Euro Rate Loan, repay all outstanding Borrowings which include such affected Non-Dollar Denominated Euro Rate Loan in full in accordance with the applicable requirements of Section 5.01;
provided that, (i) if the circumstances described in Section 2.10(a)(iii) apply to any Non-Dollar Denominated Euro Rate Loan, the Borrowers may, in lieu of taking the actions described above, maintain such
Non-Dollar Denominated Euro Rate Loan outstanding, in which case, the relevant Euro Rate shall be determined on the basis provided in the proviso to the definition of the relevant Euro Rate unless the maintenance of such Non-Dollar Denominated Euro
Rate Loan outstanding on such basis would not stop the conditions described in Section 2.10(a)(iii) from existing (in which case the actions described above, without giving 

  

 -84- 








 
effect to this proviso, shall be required to be taken) and (ii) if more than one Lender is affected at any time, then all affected Lenders must be
treated the same pursuant to this Section 2.10(b). 
 (c) If any Lender determines that after the 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 the Borrowers agree jointly and severally 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 will act reasonably and in good faith and will 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 the Borrowers, which notice shall show in reasonable detail the basis for calculation of such additional amounts. 
 2.11 Compensation. Each Borrower agrees to compensate each Lender, upon its written request (which request shall set forth in reasonable detail the basis for requesting such compensation), for all losses,
expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its Bankers’ Acceptance Loans, or Euro Rate
Loans but excluding loss of anticipated profits and Mandatory Costs) which such Lender may sustain: (i) if for any reason (other than a default by such Lender or the Administrative Agent) a Borrowing of, or conversion from or into, Euro Rate
Loans or Banker’s Acceptances Loans does not occur on a date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation (whether or not withdrawn by the respective 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 5.01, Section 5.02 or as a result of an acceleration of the Loans pursuant to
Section 11) 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 repayment (including any repayment made pursuant to Sections 5.01 or
5.02 or as a result of an acceleration of the Loans pursuant to Section 11 or as a result of the replacement of a Lender pursuant to Sections 2.13 or 13.12(b)) of any Bankers’ Acceptance Loan occurs on a date
which is not the maturity date of the respective Bankers’ Acceptance Loan, as the case may be; (iv) if any prepayment of any of its Euro Rate Loans or Bankers’ Acceptance Loans is not made on any date specified in a notice of
prepayment given by any Borrower; or (v) as a consequence of (x) any other default by any Borrower to repay Euro Rate Loans or Bankers’ Acceptance Loans when required by the terms of this Agreement or any Note or B/A Instrument held
by such Lender or (y) any election made pursuant to Section 2.10(b). Any Lender’s or the Administrative Agent’s determination of compensation owing to it under this Section 2.11 shall, absent manifest error, be
final and conclusive and binding on all the parties hereto. 
  

 -85- 








 2.12 Change of Lending Office. (a) Each Lender may at any time or from time to time
designate, by written notice to the relevant Administrative Agent to the extent not already reflected on Schedule II, one or more lending offices (which, for this purpose, may include Affiliates of the respective Lender) for the various Loans
made, and Letters of Credit participated in, by such Lender (including, in the case of Canadian Lenders, by designating a separate lending office (or Affiliate) to act as such with respect to Dollar Denominated Loans and Letter of Credit
Outstandings versus Non-Dollar Denominated Loans; provided that, for designations made after the Effective Date (unless such designation is made after the occurrence of a Conversion Event), to the extent such designation shall result in
increased costs under Section 2.10, 3.06 or 5.04 in excess of those which would be charged in the absence of the designation of a different lending office (including a different Affiliate of the respective Lender), then the
Borrowers shall not be obligated to pay such excess increased costs (although the Borrowers, in accordance with and pursuant to the other provisions of this Agreement, shall be obligated to pay the costs which would apply in the absence of such
designation and any subsequent increased costs of the type described above resulting from changes after the date of the respective designation). Each lending office and Affiliate of any Lender designated as provided above shall, for all purposes of
this Agreement, be treated in the same manner as the respective Lender (and shall be entitled to all indemnities and similar provisions in respect of its acting as such hereunder). 
 (b) Each Lender agrees that on the occurrence of any event giving rise to the operation of Section 2.10(a)(ii) or (iii),
Section 2.10(c), Section 3.06 or Section 5.04 with respect to such Lender, it will, if requested by any Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate
another lending office for any Loans or Letters of Credit affected by such event, provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the
object of avoiding the consequence of the event giving rise to the operation of such Section. Nothing in this Section 2.12(b) shall affect or postpone any of the obligations of the Borrowers or the right of any Lender provided in
Sections 2.10, 3.06 and 5.04. 
 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), Section 3.06 or
Section 5.04 with respect to any Lender which results in such Lender charging to any Borrower increased costs in excess of those being generally charged by the other Lenders or (z) in the case of a refusal by a Lender to consent to
certain proposed changes, waivers, discharges or terminations with respect to this Agreement which have been approved by the Required Lenders as (and to the extent) provided in Section 13.12(b) but which requires the consent of each
Lender or each directly affected Lender, subject to the limitations set forth in Section 2.19 Aleris shall have the right, if no Default or Event of Default then exists (or, in the case of preceding clause (z), will exist after giving
effect to such replacement), 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 13.12(b) where the consent of the respective Lender is required with respect 

  

 -86- 








 
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 respective 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 13.04(b) (and with all fees payable pursuant to said Section 13.04(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 respective 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, and all participations in all then outstanding Letters of Credit issued pursuant to the respective Tranche or Tranches where the respective Lender is being
replaced by, 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

Persons which are Eligible Assignees and which will become Lenders as provided below) provide Incremental Commitments under a Tranche and, subject to the applicable terms and conditions contained in this Agreement, make Revolving Loans pursuant

discretion to provide an Incremental Commitment and executed and delivered to the Administrative Agent an Incremental Commitment Agreement in respect thereof as provided in clause (b) of this Section 2.15, such Lender shall not be
obligated to fund any Revolving Loans in excess of its Commitment under any Tranche as in effect prior to giving effect to such Incremental Commitment provided pursuant to this Section 2.15, (ii) any Lender (including any Eligible
Assignee who will become a Lender) may so provide an Incremental Commitment without the consent of any other Lender, (iii) each provision of Incremental Commitments on a given date pursuant to this Section 2.15 shall be in a minimum

Administrative Agent and each such Lender or other Eligible Assignee which agrees to provide an Incremental Commitment (each, an “Incremental Lender”) shall execute and deliver to the Administrative Agent an Incremental Commitment
Agreement, with the effectiveness of such Incremental Lender’s Incremental Commitment to occur on the date set forth in such Incremental Commitment Agreement, which date in any event shall be no earlier than the date on which (w) all fees

(x) all Incremental Commitment Requirements are satisfied, (y) all other conditions set forth in this Section 2.15 shall have been satisfied, and (z) all other conditions precedent that may be set forth in such Incremental

under the relevant Tranche or Tranches, and incur additional Revolving Loans from certain other Lenders under the relevant Tranche or Tranches (including the Incremental Lenders), (even though as a result thereof such new Loans (to the extent
required to be maintained as Euro Rate Loans) may have a shorter Interest Period than the then outstanding Borrowings of the respective such Loans), in each case to the extent necessary so that all of the Lenders under the relevant Tranche or
Tranches participate in each outstanding borrowing of Revolving Loans under the relevant Tranche or Tranches pro rata on the basis of their respective Commitments under the relevant Tranche or Tranches (after giving effect to any
increase in the Total Commitment (and the Total U.S./European Commitment and/or Total Canadian Commitment, as applicable) pursuant to this Section 2.15) and with the relevant Borrowers under the relevant Tranche being jointly and
severally obligated to pay to the respective Lenders any costs of the type referred to in Section 2.11 and such amounts, as reasonably determined by the respective Lenders, to compensate them for funding the various Revolving Loans
during an existing Interest Period (rather than at the beginning of the respective Interest Period, based upon rates then applicable thereto) in connection with any such repayment and/or incurrence. All determinations by any Lender pursuant to the
preceding sentence shall, absent manifest error, be final and conclusive and binding on all parties hereto. 
 2.16 Interest Act (Canada);
Criminal Rate of Interest; Nominal Rate of Interest. (a) Notwithstanding anything to the contrary contained in this Agreement or in any other Credit Document, solely to the extent that a court of competent jurisdiction finally determines
that the calculation or determination of interest or any fee payable by the Canadian Borrowers in respect of the ABL Obligations pursuant to this Agreement and the other Credit Documents shall be governed by the laws of any province of Canada or the
federal laws of Canada, in no event shall the aggregate “interest” (as defined in Section 347 of the Criminal Code, R.S.C. 1985, c. C-46, as the same shall be amended, replaced or re-enacted from time to time) payable by the Canadian
Borrowers to the Agents or any Lender under this Agreement or any other Credit Document exceed the effective annual rate of interest on the “credit advances” (as defined in that section) under this Agreement or such other Credit Document
lawfully permitted under that section and, if any payment, collection or demand pursuant to this Agreement or any other Credit Document in respect of “interest” (as defined in that section) is determined to be contrary to the provisions of
that section, such payment, collection or demand shall be deemed to have been made by mutual mistake of the Agents, the Lenders and the Canadian Borrowers and the amount of such payment or collection shall be refunded by the relevant Agents and
Lenders to the Canadian Borrowers. For the purposes of this Agreement and each other Credit Document to which the Canadian Borrowers is a party, the effective annual rate of interest payable by the Canadian Borrowers shall be determined in
accordance with generally accepted actuarial practices and 

  

 -90- 








 
principles over the term of the loans on the basis of annual compounding for the lawfully permitted rate of interest and, in the event of dispute, a
certificate of a Fellow of the Canadian Institute of Actuaries appointed by the for the account of the Canadian Borrowers will be conclusive for the purpose of such determination in the absence of evidence to the contrary. 
 (b) For the purposes of the Interest Act (Canada) and with respect to Canadian Credit Parties only: 
 (i) whenever any interest or fee payable by the Canadian Borrowers is calculated using a rate based on a year of 360 days or 365 days, as
the case may be, the rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (x) the applicable rate based on a year of 360 days or 365 days, as the case may be, (y) multiplied by the actual number
of days in the calendar year in which such rate is to be ascertained and (z) divided by 360 or 365, as the case may be; and 
 (ii) all calculations of interest payable by the Canadian Borrowers under this Agreement or any other Credit Document are to be made on the basis of the nominal interest rate described herein and therein and not on the basis of effective
yearly rates or on any other basis which gives effect to the principle of deemed reinvestment of interest. The parties hereto acknowledge that there is a material difference between the stated nominal interest rates and the effective yearly rates of
interest and that they are capable of making the calculations required to determine such effective yearly rates of interest. 
 2.17
Canadian Lenders. (a) So long as no Significant Event of Default is in existence and no Conversion Event has occurred, each Canadian Lender shall at all times be a Canadian Resident or, at its option, such Canadian Lender shall designate
an Affiliate of such Lender which is a Canadian Resident (which Affiliate shall be a signatory to this Agreement and be listed on Schedule I-B hereto, or shall become a party hereto by signing an assumption agreement in form and substance
reasonably satisfactory to the Administrative Agent) to act as a Canadian Lender hereunder, in which case the Affiliate so designated as a Canadian Lender hereunder shall be required to be satisfactory to (and approved by) the Administrative Agent
and shall at all times hold the Canadian Commitment (and all extensions of credit pursuant thereto) of the respective Canadian Lender. To the extent legally entitled to do so, the Canadian Administrative Agent and each Canadian Lender shall, upon
written request by any Canadian Borrower, deliver to such Canadian Borrower or the applicable taxing authority, any form or certificate required in order that any payment by any Canadian Borrower under this Agreement may be made free and clear of,
and without deduction or withholding for or on account of, any Taxes, provided that in determining the reasonableness of such a request such Person shall be entitled to consider the cost (to the extent unreimbursed by the Canadian Borrower) which
would be imposed on such Person of complying with such request, and provided further that nothing in this Section 2.17(a) shall require a Lender to disclose any confidential information (including, without limitation, its tax returns or
its calculations). 
 (b) A Canadian Lender may change its Affiliate acting as Canadian Lender hereunder but only pursuant to an assignment
in form and substance reasonably satisfactory to the Administrative Agent (with the consent of the Administrative Agent), where the respective assignee represents and warrants, unless a Significant Event of Default is in existence or a 

  

 -91- 








 
Conversion Event has occurred, that it is an Affiliate of the respective Canadian Lender and represents and warrants that it is a Canadian Resident and will
act directly as a Canadian Lender with respect to the Canadian Commitment of the respective Canadian Lender. 
 (c) In connection with any
assignment pursuant to Section 2.13 or 13.04 of all or any part of the Canadian Commitment of any Canadian Lender the Assignment and Assumption Agreement shall, unless a Significant Event of Default is in existence or a Conversion
Event has occurred, contain the representation and warranties specified in item (2) of Section 1.2 of Annex I to Exhibit M hereto including that it is a Canadian Resident. 
 (d) The foregoing shall in no event limit the sales or purchases of participations in Canadian Revolving Loans after the occurrence of a Conversion Event
or a Significant Event of Default. 
 2.18 Provisions Regarding Bankers’ Acceptances, Drafts, etc. The parties hereto agree that
the provisions of Schedule III shall apply to all Bankers’ Acceptances, Bankers’ Acceptance Loans, Drafts and B/A Equivalent Notes created hereunder, and that the provisions of Schedule III shall be deemed incorporated by
reference into this Agreement as if such provisions were set forth in their entirety herein. 
 2.19 U.S./European Lenders. Each
Lender party hereto on the Initial Borrowing Date represents that it is a Swiss Qualifying Bank or a Swiss Non-Qualifying Bank as further indicated on Schedule I-C. Any Lender which ceases to be a Swiss Qualifying Bank shall promptly notify
Aleris that it has ceased to be a Swiss Qualifying Bank. If as a result of such event the number of Swiss Non-Qualifying Banks under this Agreement exceeds the number ten, then, so long as no Significant Event or Default is in existence, Aleris
shall have the right to request that the respective Lender assign or transfer by novation all of its rights and obligations under this Agreement to an Eligible Transferee qualifying as a Swiss Qualifying Bank or another Lender qualifying as a Swiss
Qualifying Bank, all in accordance with Section 13.04. The Administrative Agent shall have no responsibility for determining whether or not an entity is a Swiss Qualified Bank, but shall track the number of U.S./European Lenders from
time to time that were unable to represent that they were Swiss Qualifying Banks in order to determine whether the number of Swiss Non-Qualifying Banks under this Agreement exceeds the number ten; provided that the Administrative Agent shall
have no liability for any determinations made hereunder unless such liability arises from its gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a non-appealable decision). 
 SECTION 3. Letters of Credit. 
 3.01

Currency and shall be issued on a sight basis only. Each Letter of Credit shall be deemed to constitute a utilization of the U.S./European Commitments (in the case of any Letters of Credit issued for the account of the U.S. Borrowers), the European
Sub-Commitment (in the case of any Letters of Credit issued for the account of the European Borrowers) or the Canadian Commitments (in the case of any Letters of Credit issued for the account of the Canadian Borrowers), as applicable, and shall be

Credit” and collectively, the “European Letters of Credit”, shall mean any Letter of Credit issued for the account of the European Borrower. 
 (b) Subject to and upon the terms and conditions set forth herein, each Issuing Lender agrees that it will, at any time and from time to time on and after the Initial Borrowing Date and prior to the 30th day prior to
the Final Maturity Date, following its receipt of the respective Letter of Credit Request, issue for account of the respective Account Party, one or more Letters of Credit as are permitted to remain outstanding hereunder without giving rise to a
Default or an Event of Default, provided that no Issuing Lender shall be under any obligation to issue any Letter of Credit of the types described above if at the time of such issuance: 
 (i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain such
Issuing Lender from issuing such Letter of Credit or any requirement of law applicable to such Issuing Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Issuing
Lender shall prohibit, or request that such Issuing Lender refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuing Lender with respect to such Letter of Credit any
restriction or reserve or capital requirement (for which such Issuing Lender is not otherwise compensated hereunder) not in effect with respect to such Issuing Lender on the date hereof, or any unreimbursed loss, cost or expense (for which such
Issuing Lender is not otherwise compensated hereunder) which was not applicable or in effect with respect to such Issuing Lender as of the date hereof and which such Issuing Lender reasonably and in good faith deems material to it; 
  

 -93- 








 (ii) such Issuing Lender shall have received from any Borrower, any other Credit Party or
the Required Lenders prior to the issuance of such Letter of Credit notice of the type described in the second sentence of Section 3.03(b); or 
 (iii) a Lender Default exists with respect to any Lender, unless the Issuing Lender has entered into arrangements satisfactory to it and the respective Borrower to eliminate such Issuing Lender’s risk with
respect to the Lender which is the subject of the Lender Default, including by cash collateralizing such Lender’s relevant U.S./European Percentage of the Letter of Credit Outstandings. 
 (c) Schedule IV contains a description of certain letters of credit that were issued pursuant to the Existing Credit Agreement and which remain
outstanding on the Effective Date (and setting forth, with respect to each such letter of credit, (i) the name of the issuing lender, (ii) the letter of credit number, (iii) the name(s) of the account party or account parties,
(iv) the stated amount, (v) the name of the beneficiary, (vi) the expiry date and (vii) whether such letter of credit constitutes a standby letter of credit or a trade letter of credit). Each such letter of credit designated on
Schedule IV as an “Existing Letter of Credit” (if any), including any extension or renewal thereof in accordance with the terms thereof and hereof (each, as amended from time to time in accordance with the terms thereof and hereof,
an “Existing Letter of Credit”) shall constitute a “Letter of Credit” for all purposes of this Agreement and shall be deemed issued on the Effective Date; provided that no letter of credit listed on Schedule
IV and designated as a “Non-Continuing Letter of Credit” shall constitute a “Letter of Credit” for any purpose under this Agreement. 
 3.02 Maximum Letter of Credit Outstandings; Final Maturities; etc. Notwithstanding anything to the contrary contained in this Agreement, (i) no Letter of Credit shall be issued the Stated Amount of which,
when added to the Letter of Credit Outstandings (for this purpose, using the Dollar Equivalent of all amounts denominated in a currency other than U.S. Dollars) (exclusive of Unpaid Drawings which are repaid on the date of, and prior to the issuance
of, the respective Letter of Credit) at such time would exceed $35,000,000, (ii) no Letter of Credit shall be issued at any time when the Aggregate U.S./European Exposure exceeds (or would after giving effect to such issuance exceed) the Total

7.02 and 7.03 and (v) each Letter of Credit shall by its terms terminate (x) in the case of standby Letters of Credit, on or before the earlier of (A) the date which occurs 12 months after the date of the issuance

prior to the Final Maturity Date, and (y) in the case of trade Letters of Credit, on or before the earlier of (A) the date which occurs 180 days after the date of issuance thereof and (B) 30 days prior to the Final Maturity Date.

 3.03 Letter of Credit Requests; Minimum Stated Amount. (a) Whenever the respective Account Parties desire that a Letter of
Credit be issued for their account, the respective Account Parties shall give the Administrative Agent and the respective Issuing Lender at least five Business Days’ (or such shorter period as is acceptable to such Issuing Lender) 

  

 -94- 








 
written notice thereof (including by way of facsimile). Each notice shall be in the form of Exhibit C, appropriately completed (each, a
“Letter of Credit Request”) to specify: (i) the name of the respective Issuing Lender thereof; (ii) whether such Letter of Credit is to be a standby or trade Letter of Credit; (iii) the date of issuance of such Letter
of Credit (which shall be a Business Day); (iv) the initial Stated Amount of such Letter of Credit; (v) the beneficiary of such Letter of Credit and the obligations to be supported by such Letter of Credit; (vi) the stated expiration
date of such Letter of Credit and (vii) whether such Letter of Credit shall be U.S. Letter of Credit a Canadian Letter of Credit or a European Letter of Credit.

Section 6 or 7 are not then satisfied, or that the issuance of such Letter of Credit would violate Section 3.02, then such Issuing Lender shall, subject to the terms and conditions of this Agreement, issue the
requested Letter of Credit for the account of the respective Account Parties in accordance with such Issuing Lender’s usual and customary practices. Upon the issuance of or modification or amendment to any standby Letter of Credit, each Issuing
Lender shall promptly notify the respective Account Parties and the Administrative Agent in writing of such issuance, modification or amendment and such notice shall be accompanied by a copy of such Letter of Credit or the respective modification or
amendment thereto, as the case may be. Promptly after receipt of such notice the Administrative Agent shall notify the L/C Participants, in writing, of such issuance, modification or amendment. 
 (c) On the first Business Day of each week, each Issuing Lender shall furnish the Administrative Agent with a written (including via facsimile) report of
the daily aggregate outstandings of Letters of Credit issued by such Issuing Lender for the immediately preceding week. 
 (d) The initial
Stated Amount of each Letter of Credit (other than Existing Letters of Credit which shall be in the Stated Amounts shown on Schedule IV) shall not be less than $50,000 (or the equivalent amount thereof in the respective Available Currency) or
such lesser amount as is acceptable to the respective Issuing Lender. 
 3.04 Letter of Credit Participations. (a) Immediately
upon the issuance by an Issuing Lender of any Letter of Credit, such Issuing Lender shall be deemed to have sold and transferred to each Lender in the respective Tranche, and each such Lender (in its capacity under this Section 3.04,
each, an “L/C Participant”) shall be deemed irrevocably and unconditionally to have purchased and received from such Issuing Lender, without recourse or warranty, an undivided interest and participation, to the extent of such L/C
Participant’s Facility Percentage in such Letter of Credit, each Drawing or payment made thereunder and the obligations of the respective Account Parties under this Agreement with respect thereto (although Letter of Credit Fees shall be payable
directly to the Administrative Agent for the account of the respective Lenders as provided in Section 4.01(b) and the L/C Participants shall have no right to receive any portion of any Facing Fees with respect to any such Letters of
Credit), and any security therefor or guaranty pertaining thereto. Upon any change in the Commitments of any Tranche 

  

 -95- 








 
and, as a result thereof, the Facility Percentages of the respective Tranche, of the respective Lenders pursuant to Section 2.19 or 13.04,
it is hereby agreed that, with respect to all outstanding Letters of Credit and Unpaid Drawings relating thereto, there shall be an automatic adjustment to the participations pursuant to this Section 3.04 to reflect the new Facility
Percentages of the respective Lenders of the respective Tranche (or in the circumstances provided in the proviso to the immediately preceding sentence, the Percentages of the respective Lenders). With respect to each Letter of Credit from time to
time outstanding, the percentage participations therein of the various Lenders calculated as provided above in this Section 3.04(a) (including as provided in the proviso to the immediately preceding sentence) are herein called the
“L/C Participation Percentages” of the various Lenders in such Letters of Credit. 
 (b) In determining whether to pay under
any Letter of Credit, no Issuing Lender shall have any obligation relative to the other Lenders other than to confirm that any documents required to be delivered under such Letter of Credit appear to have been delivered and that they appear to
substantially comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by an Issuing Lender under or in connection with any Letter of Credit issued by it shall not create for such Issuing Lender
any resulting liability to the Account Parties, any other Credit Party, any Lender or any other Person unless such action is taken or omitted to be taken with gross negligence or willful misconduct on the part of such Issuing Lender (as determined
by a court of competent jurisdiction in a final and non-appealable decision). 
 (c) In the event that an Issuing Lender makes any payment
under any Letter of Credit issued by it and the respective Account Parties shall not have reimbursed such amount in full to such Issuing Lender pursuant to Section 3.05(a), such Issuing Lender shall promptly notify the Administrative
Agent, which shall promptly notify each relevant L/C Participant of such failure, and each such L/C Participant shall promptly and unconditionally pay to such Issuing Lender the amount of such L/C Participant’s L/C Participation Percentage of
such unreimbursed payment in the relevant Available Currency in same day funds. If the Administrative Agent so notifies, prior to 12:00 Noon (New York time) on any Business Day, any L/C Participant required to fund a payment under a Letter of
Credit, such L/C Participant shall make available to the respective Issuing Lender in the relevant Available Currency such L/C Participant’s L/C Participation Percentage of the amount of such payment on such Business Day in same day funds. If
and to the extent such L/C Participant shall not have so made its L/C Participation Percentage of the amount of such payment available to the respective Issuing Lender, such L/C Participant agrees to pay to such Issuing Lender, forthwith on demand
such amount, together with interest thereon, for each day from such date until the date such amount is paid to such Issuing Lender at the overnight Federal Funds Rate for the first three days and at the interest rate applicable to Revolving Loans
that are maintained as Base Rate Loans for each day thereafter. The failure of any such L/C Participant to make available to an Issuing Lender its L/C Participation Percentage of any payment under any Letter of Credit issued by such Issuing Lender
shall not relieve any such other L/C Participant of its obligation hereunder to make available to such Issuing Lender its L/C Participation Percentage of any payment under any Letter of Credit on the date required, as specified above, but no such
L/C Participant shall be responsible for the failure of any such other L/C Participant to make available to such Issuing Lender such other L/C Participant’s L/C Participation Percentage of any such payment. 
  

 -96- 








 (d) Whenever an Issuing Lender receives a payment of a reimbursement obligation (or interest thereon) as

reimbursed by the respective Account Party, an “Unpaid Drawing”), not later than one Business Day following receipt by the respective Account Party of notice of such payment or disbursement (provided that no such notice shall
be required to be given if a Default or an Event of Default under Section 11.05 shall have occurred and be continuing, in which case the Unpaid Drawing shall be due and payable immediately without presentment, demand, protest or notice
of any kind (all of which are hereby waived by the Borrowers)), with interest on the amount so paid or disbursed by such Issuing Lender, to the extent not reimbursed prior to 12:00 Noon (New York time) on the date of such payment or disbursement,
from and including the date paid or disbursed to but excluding the date such Issuing Lender was reimbursed by the respective Account Parties therefor at a rate per annum equal to the Base Rate in effect from time to time plus the Applicable
Margin as in effect from time to time for Revolving Loans that are maintained as Base Rate Loans; provided, however, to the extent such amounts are not reimbursed prior to 12:00 Noon (New York time) on the third Business Day following

including, without limitation, any defense based upon the failure of any drawing under a Letter of Credit to conform to the terms of the Letter of Credit or any nonapplication or misapplication by the beneficiary of the proceeds of such Drawing;
provided, however, that the Borrowers shall not be obligated to reimburse any Issuing Lender for any wrongful payment made by such Issuing Lender under a Letter of Credit issued by it as a result of acts or omissions constituting

Participant, or (ii) impose on any Issuing Lender or any L/C Participant any other conditions relating, directly or indirectly, to this Agreement or any Letter of Credit; and the result of any of the foregoing is to increase the cost to any
Issuing Lender or any L/C Participant of issuing, maintaining or participating in any Letter of Credit, or reduce the amount of any sum received or receivable by any Issuing Lender or any L/C Participant hereunder or reduce the rate of return on its
capital with respect to the Letters of Credit (except for changes in the rate of tax on, or determined by reference to, the net income or net profits (or any franchise or similar tax imposed in lieu of a net income or net profits tax

country or national jurisdiction (or any political subdivision thereof) in which it is organized or in which its principal office or applicable lending office is located), then, upon the delivery of the certificate referred to below to the Account
Parties by any Issuing Lender or any L/C Participant (a copy of which certificate shall be sent by such Issuing Lender or such L/C Participant to the Administrative Agent), such Account Party agrees to pay to such Issuing Lender or such L/C
Participant such additional amount or amounts as will compensate such Issuing Lender or such L/C Participant for such increased cost or reduction in the amount receivable or reduction on the rate of return on its capital. Any Issuing Lender or any
L/C Participant, upon determining that any additional amounts will be payable pursuant to this Section 3.06, will give prompt written notice thereof to the respective Account Party, which notice shall include a certificate submitted to
such Account Party by such Issuing Lender or such L/C Participant (a copy of which certificate shall be sent by such Issuing Lender or such L/C Participant to the Administrative Agent), setting forth in reasonable detail the basis for and the
calculation of such additional amount or amounts necessary to compensate such Issuing Lender or such L/C Participant. The certificate required to be delivered pursuant to this Section 3.06 shall, absent manifest error, be final and
conclusive and binding on the Borrowers.

such termination pursuant to Section 5.01(b) (at which time Schedule I-A shall be deemed modified to reflect such changed amounts) and (y) such Lender’s L/C Participation Percentage of all outstanding Letters of Credit

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

requirements of, said Section 13.12(b) so long as (i) in the case of the repayment of Revolving Loans of any Lender of any Tranche pursuant to this Section 5.01(b), (x) the Commitments of the respective Tranche or

Subsidiaries (other than cash and Cash Equivalents which are Restricted, on deposit in an Exempted Deposit Account or to be applied to repay Term Loans) is less than $100,000,000, the amounts required to be applied pursuant to such Sections (before
giving effect to this clause (h)) shall be applied first to the repayment of the Loans to the extent required to cause the Sum to equal $100,000,000 and thereafter to the Term Loans to the extent required under the Term Loan Agreement.

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

Administrative Agent or the applicable Lender, as the case may be, under this Agreement and under any Note. In addition, the Administrative Agent and each
Lender to the U.S. Borrowers agrees that from time to time after the 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 tax

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

  

 -116- 








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

  

 -117- 








 
certificate or document or to furnish to the relevant non-U.S. Borrower any information, in each case, as reasonably requested by such non-U.S. Borrower that
may be necessary to establish any available exemption from, or reduction in the amount of, any Taxes; provided, however, that nothing in this Section 5.04(c) shall require a Lender to disclose any confidential information
(including, without limitation, its tax returns or its calculations). 
 (d) If a Borrower pays any additional amount under this
Section 5.04 to a Section 5.04 Indemnitee, and such Section 5.04 Indemnitee determines in its reasonable discretion that it has actually received or realized in connection therewith any refund or any reduction of,
or credit against (including, for the avoidance of doubt, any foreign tax credit), its tax liabilities in or with respect to the taxable year in which the additional amount is paid (a “Tax Benefit”), such Section 5.04
Indemnitee shall pay to such Borrower an amount that the Section 5.04 Indemnitee shall, in its reasonable discretion, determine is equal to the net benefit, after tax, which was obtained by such Section 5.04 Indemnitee in
such year as a consequence of such Tax Benefit; provided, however, that (i) any Section 5.04 Indemnitee may determine, in its sole discretion consistent with the policies of such Section 5.04 Indemnitee,
whether to seek a Tax Benefit; (ii) any taxes that are imposed on a Section 5.04 Indemnitee as a result of a disallowance or reduction (including through the expiration of any tax credit carryover or carryback of such
Section 5.04 Indemnitee that otherwise would not have expired) of any Tax Benefit with respect to which such Section 5.04 Indemnitee has made a payment to such Borrower pursuant to this Section 5.04(d) shall be
treated as a Tax for which such Borrower is obligated to indemnify such Section 5.04 Indemnitee pursuant to this Section 5.04 without any exclusions or defenses; (iii) nothing in this Section 5.04(d) shall
require any Section 5.04 Indemnitee to disclose any confidential information to any Borrower (including, without limitation, its tax returns or its calculations); and (iv) no Section 5.04 Indemnitee shall be required to
pay any amounts pursuant to this Section 5.04(d) at any time that a Default or an Event of Default exists. 
 5.05 Minimum
Interest Rates and Payments. (a) The various rates of interests provided for in this Agreement (including, without limitation, under Section 2.08) are minimum interest rates. 
 (b) When entering into this Agreement, each party hereto has assumed that the payments required under this Agreement are not and will not become subject
to Swiss Withholding Tax. Notwithstanding that the parties hereto do not anticipate that any payment will be subject to Swiss Withholding Tax, they agree that, in the event that Swiss Withholding Tax should be imposed on interest or other payments
(the “Relevant Amount”) by a Swiss Obligor, any payment of interest due by such Swiss Obligor shall, subject to the provisions of this Agreement, be increased to an amount which (after making any deduction of the Swiss Withholding
Tax) results in a payment to each Lender entitled to such payment of an amount equal to the payment which would have been due had no deduction of Swiss Withholding Tax been required. For this purpose, the Swiss Withholding Tax shall be calculated on
the full grossed-up amount. 
 (c) The European Borrower shall not be required to make an increased payment to any specific Lender (but
without prejudice to the rights of all other Lenders hereunder) under paragraph (b) above or under Section 5.04 in connection with a Swiss Withholding Tax if the European Borrower has breached the Ten Non-Bank Regulations and/or


  

 -118- 








 
Twenty Non-Bank Regulations as a direct result of (i) the incorrectness of the representation made by such Lender on the Initial Borrowing Date pursuant
to the first sentence of Section 2.19 (if Schedule I-C specified that such Lender was a Swiss Qualifying Lender) or (ii) such Lender, as assignee or participant, breaching the requirements and limitations for transfers,
assignments or sub-participations (including Restricted Sub-Participations) pursuant to Section 13.04. 
 (d) For the avoidance
of doubt, the European Borrower shall be required to make an increased payment to a specific Lender under paragraph (b) above in connection with the imposition of a Swiss Withholding Tax if the European Borrower has breached the Ten Non-Bank
Regulations and/or the Twenty Non-Bank Regulations as a result of its failure to comply with the provisions of Section 10.10 or, if after a Significant Event of Default or Conversion Event, lack of compliance with the Ten Non-Bank
Regulations and/or the Twenty Non-Bank Regulations as a result of assignments or participation effected in accordance herewith. 
 (e) If
requested by the Administrative Agent, a Swiss Obligor shall provide to the Administrative Agent those documents which are required by law and applicable double taxation treaties to be provided by the payer of such tax for each relevant Lender to
prepare a claim for refund of Swiss Withholding Tax. In the event Swiss Withholding Tax is refunded to the Lender by the Swiss Federal Tax Administration, the relevant Lender shall forward, after deduction of costs, such amount to the Swiss Obligor;
provided, however, that (i) the relevant Swiss Obligor has fully complied with its obligations under this Section 5.05; (ii) the relevant Lender may determine, in its sole discretion, consistent with the policies
of such Lender, the amount of the refund attributable to Swiss Withholding Tax paid by the relevant Swiss Obligor; (iii) nothing in this Section 5.05 shall require the Lender to disclose any confidential information to the Swiss
Obligor (including, without limitation, its tax returns); and (iv) no Lender shall be required to pay any amounts pursuant to this Section 5.05 at any time which a Default or Event of Default exists.

Borrowers taken together as a whole, the U.S. Borrowers and their Subsidiaries taken as a whole, the Canadian Borrowers taken together as a whole, the Canadian Borrowers and their Subsidiaries taken as a whole, the European Borrower individually and
the European Borrower and its Subsidiaries taken as a whole, as the case may be, has or have not incurred and does or do not intend to incur, and does or do not believe that it or they will incur, debts beyond its or their respective ability to pay

The amount of contingent liabilities at any time shall be computed as the amount that, in the light of all the facts and circumstances existing at such time,
represents the amount that can reasonably be expected to become an actual or matured liability. 
 (d) Except for the Existing Letters of
Credit outstanding on the Initial Borrowing Date or as disclosed in the financial statements delivered pursuant to Section 8.05(a), there were as of the Initial Borrowing Date no liabilities or obligations with respect to Aleris or any
of its Subsidiaries of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due, but not including accounts payable, accrued liabilities incurred in the ordinary course of business and contractual obligations
of a type not required to be disclosed in financial statements or footnotes thereto) which, either individually or in the aggregate, could reasonably be expected to be material to Aleris and its Subsidiaries taken as a whole. 
 (e) The Projections delivered to the Administrative Agent and the Lenders prior to the Initial Borrowing Date have been prepared in good faith and are
based on assumptions which were believed by management of Aleris to be reasonable when made. On the Initial Borrowing Date, Aleris and each Borrower believe that the Projections are reasonable and attainable, it being recognized by the Lenders,
however, that projections as to future events are not to be viewed as facts and that the actual results during the period or periods covered by the Projections may differ from the projected results and such differences may be material. 

(f) Since December 31, 2005, there has been no change in the financial condition, results of operations or business of Aleris and its
Subsidiaries, which individually or in the aggregate has had, or reasonably could be expected to cause in the future, a Material Adverse Effect.

Administrative Agent. 
 (e) The Borrowers agree that each action required by clauses (a) through (d) of this

convenience in maintaining a record of the Collateral, such written statements and schedules as the Collateral Agent may reasonably require, including, without limitation, those described in Section 9.01, designating, identifying or
describing the Collateral pledged or granted to the Lenders under the Security Documents. The failure by any Borrower or any of their respective Subsidiaries, however, to promptly give the Collateral Agent such statements or schedules shall not
affect, diminish, modify or otherwise limit the Collateral Agent’s security interests (for the benefit of the Lenders) in the Collateral. 
 9.15 Permitted Acquisitions. (a) Subject to the provisions of this Section 9.15 and the requirements contained in the definition of Permitted Acquisition, Aleris and each of its Subsidiaries may from time to time

any Note by the acceptance of such Note shall be deemed irrevocably to authorize, the Facility Agents 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 each Facility Agent by the terms hereof and thereof and such other powers as are reasonably
incidental thereto. Each Facility Agent may perform any of its respective 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 (x) 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 a currency other than U.S. Dollars and (y) the Collateral Agent shall be permitted to designate one of its affiliates (including, without limitation, Citibank Canada) to perform the duties to be performed by the Collateral Agent

or such Affiliate or Subsidiary, and the provisions of this Section 12 shall apply to any such affiliates mutatis mutandis).

 -180- 








 
benefit of its affiliates), each Issuing Lender, the Canadian Administrative Agent, the Collateral Agent and each other Agent (all such Lenders (for their
benefit and the benefit of their respective affiliates), Issuing Lenders, Canadian Administrative Agent, Collateral Agent and other Agents are collectively called, for purposes of this Section 12.01(b), the “Quebec Secured
Parties”) hereby acknowledges and agrees that Citibank Canada shall, for purposes of holding any security granted by the Canadian Borrowers or by any Affiliate or Subsidiary of the Canadian Borrowers on property pursuant to the laws of the
Province of Quebec to secure obligations of the Canadian Borrowers or such Affiliate or Subsidiary under any bond or debenture (the “Quebec Secured Obligations”), be the holder of an irrevocable power of attorney (fondé de
pouvoir) (within the meaning of the Civil Code of Quebec) for all present and future Quebec Secured Parties and holders of any bond or debenture. Each of the Quebec Secured Parties, for itself and for all present and future affiliates

Civil Code of Quebec) in order to hold security granted by any of the Canadian Borrowers or by any of their Affiliate or Subsidiaries in the Province of Quebec to secure the Quebec Secured Obligations. Furthermore, each of the Quebec Secured
Parties hereby appoints the Citibank Canada to act in the capacity of the holder and depositary of such bond or debenture on its own behalf as Collateral Agent and for and on behalf and for the benefit of all present and future Quebec Secured

(fondé de pouvoir) by execution of the relevant Assignment and Assumption Agreement or other relevant documentation relating to such assignment. Notwithstanding the provisions of Section 32 of the An Act respecting the special
powers of legal persons (Quebec), Citibank Canada may acquire and be the holder of any bond or debenture. The Canadian Borrowers hereby acknowledge that such bond or debenture constitutes a title of indebtedness, as such term is used in Article
2692 of the Civil Code of Quebec. 
 12.02 Nature of Duties. (a) No Facility Agent shall have any duties or
responsibilities except those expressly set forth in this Agreement and in the other Credit Documents. Neither the Facility Agents nor any of their respective 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 Facility Agents shall be mechanical and administrative in nature; no Facility Agent shall 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 any Facility 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 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 

  

 -181- 








 
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 Facility Agents (to the same extent as provided for the Facility Agents) as, and to the extent, provided for under
Sections 12.06 and 13.01 (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. 
 12.03 Lack of Reliance on the Facility Agents. Independently and without reliance upon any Facility 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 Letters of Credit 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, no Facility Agent shall 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 the issuance of any Letter of Credit or at any
time or times thereafter. No Facility Agent shall 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

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. 
 12.04 Certain Rights of the Facility
Agents. If a Facility 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, such Facility Agent shall be entitled to
refrain from such act or taking such action unless and until such Facility Agent shall have received instructions from the Required Lenders; and such Facility 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 any Facility Agent as a result of such Facility Agent acting or refraining from acting hereunder or under any other Credit Document in
accordance with the instructions of the Required Lenders. 
 12.05 Reliance. Each Facility 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 message signed, sent or made by any Person that such
Facility 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 such Facility Agent.

  

 -182- 








 12.06 Indemnification. To the extent any Facility Agent (or any affiliate thereof) is not
reimbursed and indemnified by the Borrowers, the Lenders will reimburse and indemnify such Facility 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 such Facility 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 such Facility Agent’s (or such affiliate’s) gross negligence or
willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision). 
 12.07 The Facility
Agents in their Individual Capacities. With respect to its obligation to make Loans, or issue or participate in Letters of Credit, under this Agreement, each Facility 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 each Facility Agent in its respective individual capacity. Each Facility Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of banking,
investment banking, trust or other business with, or provide debt financing, equity capital or other services (including financial advisory services) to any Credit Party or any Affiliate of any Credit Party (or any Person engaged in a similar
business with any Credit Party or any Affiliate thereof) as if they were not performing the duties specified herein, and may accept fees and other consideration from any Credit Party or any Affiliate of any Credit Party for services in connection
with this Agreement and otherwise without having to account for the same to the Lenders. 
 12.08 Holders. The Borrowers and the
Facility Agents shall deem and treat the payee of any Note as the owner thereof for all purposes hereof unless and until a written notice of the assignment, transfer or endorsement thereof, as the case may be, together with the relevant Assignment
and Assumption Agreement shall have been filed with the Administrative Agent or the Canadian Administrative Agent, as applicable. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or
consent, is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee, assignee or endorsee, as the case may be, of such Note or of any Note or Notes issued in exchange therefor. 
 12.09 Resignation by the Facility Agents. (a) Any Facility 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 a Default or an Event of Default under Section 11.05 then exists, Aleris. Any such resignation
by a Facility Agent hereunder shall also constitute its resignation as an Issuing Lender and Swingline Lender, in which case the resigning Facility Agent (x) shall not be 

  

 -183- 








 
required to issue any further Letters of Credit or make any additional Swingline Loans hereunder and (y) shall maintain all of its rights as Issuing
Lender or Swingline Lender, as the case may be, with respect to any Letter of Credit issued by it, or Swingline Loans made by it, prior to the date of such resignation. Such resignation shall take effect upon the appointment of a successor
Administrative Agent, Canadian Administrative Agent or Collateral Agent, as applicable, pursuant to clauses (b) and (c) below or as otherwise provided below. 
 (b) Upon any such notice of resignation by any Facility Agent, the Required Lenders shall appoint a successor Administrative Agent, Canadian 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, Canadian Administrative Agent or Collateral Agent, as applicable, shall not have been so
appointed within such 20 Business Day period, the respective Facility Agent, 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, Canadian Administrative Agent or Collateral Agent, as applicable, who shall serve as Administrative Agent, Canadian Administrative Agent or Collateral Agent, as applicable,
hereunder or thereunder until such time, if any, as the Required Lenders appoint a successor Administrative Agent, Canadian Administrative Agent or Collateral Agent, as applicable, as provided above. 
 (d) If no successor Administrative Agent, Canadian Administrative Agent or Collateral Agent, as applicable, has been appointed pursuant to clause
(b) or (c) above by the 45th Business Day after the date such notice of resignation was given by the respective Facility Agent, such Facility Agent’s resignation shall become effective and the Required Lenders shall thereafter perform
all the duties of the respective Facility Agent hereunder and/or under any other Credit Document until such time, if any, as the Required Lenders appoint a successor Administrative Agent, Canadian Administrative Agent or Collateral Agent, as
applicable, as provided above. 
 (e) Upon a resignation of any Facility Agent pursuant to this Section 12.09, such Facility
Agent shall remain indemnified to the extent provided in this Agreement and the other Credit Documents and the provisions of this Section 12 shall continue in effect for the benefit of such Facility Agent for all of its actions and
inactions while serving as a Facility Agent. 
 12.10 Collateral Matters. (a) Each Lender authorizes and directs the Facility
Agents 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 Facility Agents are hereby 

  

 -184- 








 
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 perfected the security interest in and liens upon the Collateral granted pursuant to the Security Documents. Each of the
Administrative Agent and the Canadian Administrative Agent hereby acknowledges that any Collateral in its possession shall be held for the benefit of the Collateral Agent, subject to the security interests created under the Security Documents and
shall act upon the instructions of the Collateral Agent, without the further consent of any Borrower. The Collateral Agent may perform any of its duties hereunder or thereunder by or through its authorized agents, sub-agents or employees.

 (b) The Lenders hereby authorize each Facility Agent to release any Lien granted to or held by such Facility Agent upon any Collateral
(i) upon termination of the Commitments and payment and satisfaction of all of the ABL Obligations at any time arising under or in respect of this Agreement or the Credit Documents or the transactions contemplated hereby or thereby,
(ii) constituting property being sold or otherwise disposed of (to Persons other than Aleris and its Subsidiaries) upon the sale or other disposition thereof in compliance with Section 10.02, (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 12.10(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 13.12) or (v) as otherwise may be expressly provided in the relevant Security Documents. Upon request by any Facility Agent at any time, the Lenders will
confirm in writing such Facility Agent’s authority to release particular types or items of Collateral pursuant to this Section 12.10. 
 (c) No Facility Agent shall have any 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 any Facility 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 any Facility Agent in this Section 12.10 or in any of the Security Documents, it being understood and agreed
that in respect of the Collateral, or any act, omission or event related thereto, each Facility Agent may act in any manner it may deem appropriate, in its sole discretion, given such Facility Agent’s own interest in the Collateral as one of
the Lenders and that such Facility 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). It
is understood and agreed that the Collateral Agent is a “Facility Agent” and shall be entitled to all indemnification and reimbursement rights in favor of the Facility Agents (to the same extent as provided for the Facility Agents) as, and
to the extent, provided for under Sections 12.06 and 13.01 (which provisions shall be deemed incorporated by reference herein). 
 (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. 
  

 -185- 








 12.11 Delivery of Information. The Facility Agents shall not be required to deliver to any Lender
originals or copies of any documents, instruments, notices, communications or other information received by any Facility Agent from any Credit Party, any Subsidiary, the Required Lenders, any Lender or any other Person under or in connection with
this Agreement or any other Credit Document except (i) as specifically provided in this Agreement or any other Credit Document and (ii) as specifically requested from time to time in writing by any Lender with respect to a specific
document, instrument, notice or other written communication received by and in the possession of the respective Facility Agent at the time of receipt of such request and then only in accordance with such specific request. 
 12.12 The Administrative Agent and the Collateral Agent. If the Administrative Agent or the Collateral Agent proposes any (or proposes any
adjustment or revision to any existing) reserves, advance rates or any other borrowing base eligibility standards, or makes any other proposal regarding a determination or action which may be made by the Administrative Agent or the Collateral Agent
pursuant to this Agreement or any other Credit Document, the non-proposing party shall respond to such proposal within three Business Days. In the event that the Administrative Agent and the Collateral Agent cannot agree on reserves, advance rates,
any other borrowing base eligibility standards or any other action or determination which may be made by the Administrative Agent or the Collateral Agent pursuant to this Agreement or any other Credit Document, the determination shall be made by the
Administrative Agent or the Collateral Agent, as applicable, either asserting the more conservative judgment or declining to permit the requested action for which consent is being sought by the Credit Parties, as applicable. 
 SECTION 13. Miscellaneous. 
 13.01
Payment of Expenses, etc. The U.S. Credit Parties hereby jointly and severally agree to: (i) whether or not the transactions herein contemplated are consummated, pay all reasonable out-of-pocket costs and expenses of each Facility Agent
and its affiliates (including, without limitation, the reasonable fees and disbursements of White & Case LLP and each Facility Agent’s other counsel and consultants) in connection with the preparation, execution, delivery and
administration of this Agreement and the other Credit Documents and the documents and instruments referred to herein and therein and any amendment, waiver or consent relating hereto or thereto, of each Facility Agent and its Affiliates in connection
with its or their syndication efforts with respect to this Agreement; (ii) pay all out-of-pocket costs and expenses of each Facility Agent and, after the occurrence of an Event of Default, each of the Issuing Lenders and Lenders in connection
with the enforcement of this Agreement and the other Credit Documents and the documents and instruments referred to herein and therein or in connection with any refinancing or restructuring of the credit arrangements provided under this Agreement in
the nature of a “work-out” or pursuant to any insolvency or bankruptcy proceedings (including, in each case without limitation, the fees and disbursements of counsel and consultants for the Facility Agent and, after the occurrence of an
Event of Default, counsel for each of the Issuing Lenders and Lenders); (iii) pay and hold each Facility Agent, each of the Issuing Lenders and each of the Lenders harmless from and against any and all present and future stamp, documentary
transfer, sales and use, value added, excise and other similar taxes with respect to the foregoing matters, the performance of any obligation under this Agreement or any other Credit Document or any payment thereunder, and save each Facility Agent,
each of the Issuing Lenders and each of the Lenders harmless from and against any and all liabilities with 

  

 -186- 








 
respect to or resulting from any delay or omission (other than to the extent attributable to such Facility Agent, such Issuing Lender or such Lender) to pay
such taxes; and (iv) indemnify each Facility Agent, each Issuing Lender and each Lender, and each of their respective officers, directors, employees, representatives, agents, affiliates, trustees and investment advisors (individually, an
“Indemnitee”, and collectively, the “Indemnitees”) from and hold each of them harmless against any and all liabilities, obligations (including Remedial Actions), losses, damages, penalties, claims, actions,
judgments, suits, costs, expenses and disbursements (including reasonable attorneys’ and consultants’ fees and disbursements) incurred by, imposed on or assessed against any of them as a result of, or arising out of, or in any way related
to, or by reason of, (a) any investigation, litigation or other proceeding (whether or not any Indemnitee is a party thereto and whether or not such investigation, litigation or other proceeding is brought by or on behalf of any Credit Party)
related to the entering into and/or performance of this Agreement or any other Credit Document or the use of any Letter of Credit or the proceeds of any Loans hereunder or the consummation of the Transaction or any other transactions contemplated
herein or in any other Credit Document or the exercise of any of their rights or remedies provided herein or in the other Credit Documents (but excluding any losses, liabilities, claims, damages or expenses to the extent (x) incurred by reason
of the gross negligence or willful misconduct of the Person to be indemnified (as determined by a court of competent jurisdiction in a final and non-appealable decision), (y) brought solely by an Affiliate of the Person to be indemnified), or
(b) the actual or alleged presence of Hazardous Materials in the air, surface water or groundwater or on the surface or subsurface of any Real Property at any time owned, leased or operated by Aleris or any of its Subsidiaries, the generation,
storage, transportation, handling or disposal of Hazardous Materials by Aleris or any of its Subsidiaries at any location, whether or not owned, leased or operated by Aleris or any of its Subsidiaries, the non-compliance by Aleris or any of its
Subsidiaries with any Environmental Law (including applicable permits thereunder) applicable to any Real Property, or any Environmental Claim asserted against Aleris, any of its Subsidiaries or any Real Property at any time owned, leased or operated
by Aleris or any of its Subsidiaries, including, in each case, without limitation, the reasonable fees and disbursements of counsel and other consultants incurred in connection with any such investigation, litigation or other proceeding (but
excluding any losses, liabilities, claims, damages or expenses to the extent (x) incurred by reason of the gross negligence or willful misconduct of the Person to be indemnified (as determined by a court of competent jurisdiction in a final and
non-appealable decision), (y) brought solely by an Affiliate of the Person to be indemnified) or (z) resulting solely from acts or omissions by Persons other than Aleris and its Subsidiaries with respect to the applicable Real Property
after the Administrative Agent sells the respective Real Property pursuant to a foreclosure or has accepted a deed in lieu of foreclosure; provided that the Credit Parties shall not be required to reimburse the legal fees and expenses of more
than one outside counsel (in addition to and necessary or advisable special counsel and up to one local counsel in each applicable local jurisdiction) for all Indemnitees unless, in the written opinion of outside counsel reasonably satisfactory to
the Credit Parties and the Administrative Agent, representation of all such Indemnitees would be inappropriate due to the existence of an actual or potential conflict of interest. To the extent that the undertaking to indemnify, pay or hold harmless
any Facility Agent, any Issuing Lender or any Lender set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, the Borrowers shall make the maximum contribution to the payment and satisfaction of
each of the indemnified liabilities which is permissible under applicable law. None of 

  

 -187- 








 
Indemnitees shall be responsible or liable to the Credit Parties or any other Person for (and each of the Credit Parties hereby waives) any indirect,
special, punitive or consequential damages (including, without limitation, any loss of profits, business or anticipated savings) which may be alleged as a result of the Credit Documents or the transactions contemplated hereby and thereby.

 13.02 Right of Setoff. (a) In addition to any rights now or hereafter granted under applicable law or otherwise, and not by
way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default, the Administrative Agent, each Issuing Lender and each Lender is hereby authorized at any time or from time to time, without presentment,
demand, protest or other notice of any kind to any Credit Party or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by the Administrative Agent, such Issuing Lender or such Lender (including, without limitation, by Affiliates, branches and agencies of the Administrative Agent, such Issuing Lender or such Lender wherever located) to or for
the credit or the account of Aleris or any of its Subsidiaries against and on account of the ABL Obligations and liabilities of the Credit Parties to the Administrative Agent, such Issuing Lender or such Lender under this Agreement or under any of
the other Credit Documents, including, without limitation, all interests in ABL Obligations purchased by such Lender pursuant to Section 13.06(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, such Issuing Lender or such Lender shall have made any demand hereunder and although said ABL Obligations, liabilities or claims, or any of them, shall
be contingent or unmatured, provided, however, that none of the Administrative Agent, any Issuing Lender or any Lender may offset amounts (i) owed by it to the Canadian Credit Parties (or any of their Subsidiaries) against amounts
owed to such Person by the U.S. Credit Parties (except in respect of the U.S. Credit Parties’ guaranties of the Canadian Credit Parties) or the European Credit Parties and (ii) owed by it to the European Credit Parties (or any of their
Subsidiaries) against amounts owed to such Person by the U.S. Credit Parties (except in respect of the U.S. Credit Parties’ guaranties of the European Credit Parties) or the Canadian Credit Parties. 
 (b) NOTWITHSTANDING THE FOREGOING SUBSECTION (a), AT ANY TIME THAT THE LOANS OR ANY OTHER OBLIGATION SHALL BE SECURED BY REAL PROPERTY LOCATED IN
CALIFORNIA, NO LENDER OR THE ADMINISTRATIVE AGENT SHALL EXERCISE A RIGHT OF SETOFF, LIEN OR COUNTERCLAIM OR TAKE ANY COURT OR ADMINISTRATIVE ACTION OR INSTITUTE ANY PROCEEDING TO ENFORCE ANY PROVISION OF THIS AGREEMENT OR ANY NOTE UNLESS IT IS TAKEN
WITH THE CONSENT OF THE REQUIRED LENDERS OR, TO THE EXTENT REQUIRED BY SECTION 13.12 OF THIS AGREEMENT, ALL OF THE LENDERS, OR APPROVED IN WRITING BY THE ADMINISTRATIVE AGENT, IF SUCH SETOFF OR ACTION OR PROCEEDING WOULD OR MIGHT (PURSUANT TO
CALIFORNIA CODE OF CIVIL PROCEDURE SECTIONS 580a, 580b, 580d AND 726 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE OR SECTION 2924 OF THE CALIFORNIA CIVIL CODE, IF APPLICABLE, OR OTHERWISE) AFFECT OR IMPAIR THE VALIDITY, PRIORITY, OR ENFORCEABILITY OF
THE LIENS GRANTED TO THE COLLATERAL AGENT PURSUANT TO THE SECURITY DOCUMENTS OR THE ENFORCEABILITY OF THE NOTES AND OTHER OBLIGATIONS HEREUNDER, AND 

  

 -188- 








 
ANY ATTEMPTED EXERCISE BY ANY LENDER OR THE ADMINISTRATIVE AGENT OF ANY SUCH RIGHT WITHOUT OBTAINING SUCH CONSENT OF THE REQUIRED LENDERS OR THE
ADMINISTRATIVE AGENT SHALL BE NULL AND VOID. THIS SUBSECTION (b) SHALL BE SOLELY FOR THE BENEFIT OF EACH OF THE LENDERS AND THE ADMINISTRATIVE AGENT HEREUNDER. 
 13.03 Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including telegraphic, telex, telecopier or cable communication)

Lender in a written notice to Aleris and the Administrative Agent. All such notices and communications shall, when mailed, telegraphed, telexed, telecopied, or cabled or sent by overnight courier, be effective when deposited in the mails, delivered
to the telegraph company, cable company or overnight courier, as the case may be, or sent by telex or telecopier, except that notices and communications to the Administrative Agent and Aleris shall not be effective until received by the
Administrative Agent or Aleris, as the case may be. 
 13.04 Benefit of Agreement; Assignments; Participations. (a) This
Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, however, no Borrower may assign or transfer any of its rights, obligations or
interest hereunder without the prior written consent of all of the Lenders and, provided further, that, although (subject to clauses (c) and (d) below) any Lender may transfer, assign or grant participations in its rights hereunder,
such Lender shall remain a “Lender” for all purposes hereunder (and may not transfer or assign all or any portion of its Commitments hereunder except as provided in Sections 2.13 and 13.04(b)) and the transferee, assignee or
participant, as the case may be, shall not constitute a “Lender” hereunder and, provided further, that no Lender shall transfer or grant any participation under which the participant shall have rights to approve any amendment to or
waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) extend or postpone the final scheduled maturity or any date fixed for any scheduled repayment of principal of, or interest on, the
Commitments and/or Loans (or Letters of Credit) that are being participated in by such participant, (ii) reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with a waiver of applicability of any
post-default increase in interest rates) or reduce the principal amount thereof, or increase the amount of the participant’s participation over the amount thereof then in effect (it being understood that a waiver of any Default or Event 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 

  

 -189- 








 
of the Security Documents (except as expressly provided in the Credit Documents) supporting the Loans or Letters of Credit hereunder in which such
participant is participating. In the case of any such participation, (A) 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,
(B) following a Conversion Event each Participant shall be entitled to receive from relevant Borrowers any incremental costs and indemnities (including, without limitation, pursuant to Section 2.10, 2.11 and 3.06, and
5.04) directly from the Borrowers to the same extent as if it were the direct Lender as to which its interests were assigned after the occurrence of a Conversion Event as opposed to a participant therein, which incremental costs shall be
calculated without regard to Section 2.12 and (C) each participant shall have acknowledged in writing that it is bound by the terms of the Re-allocation Agreement. 
 (b) Notwithstanding the foregoing and subject to clauses (c) and (d) below, any Lender (or any Lender together with one or more other Lenders)
may (x) assign all or a portion of its Commitments and related outstanding ABL Obligations (or, if the Commitments with respect to the relevant Tranche have terminated, outstanding ABL Obligations) hereunder to (i)(A) its parent company and/or
any affiliate of such Lender which is at least 50% owned by such Lender or its parent company or (B) to one or more other Lenders or any affiliate of any such other Lender which is at least 50% owned by such other Lender or its parent company
(provided that any fund that invests in loans and is managed or advised by the same investment advisor of another fund which is a Lender (or by an Affiliate of such investment advisor) shall be treated as an affiliate of such other Lender for
the purposes of this sub-clause (x)(i)(B)), or (ii) in the case of any Lender that is a fund that invests in loans, any other fund that invests in loans and is managed or advised by the same investment advisor of any Lender or by an Affiliate
of such investment advisor or (y) assign all, or if less than all, a portion equal to at least $5,000,000 (for such purposes, using the Dollar Equivalent of any Non-Dollar Denominated Loans), in each case in the aggregate for the assigning
Lender or assigning Lenders of such Commitments and related outstanding ABL Obligations (or, if the Commitments with respect to the relevant Tranche have terminated, outstanding ABL Obligations) hereunder to one or more Eligible Transferees
(treating any fund that invests in loans and any other fund that invests in loans and is managed or advised by the same investment advisor of such fund or by an Affiliate of such investment advisor as a single Eligible Transferee), each of which
assignees shall become a party to this Agreement as a Lender by execution of an Assignment and Assumption Agreement, provided that (i) so long as no Significant Event of Default then exists and no Conversion Event has occurred, any
assignment of all or any portion of the Canadian Commitment of any Lender pursuant to clause (x) or (y) above shall be only to a Person who is a Canadian Resident complying with the relevant requirements of Section 2.17,
(ii) at such time, Schedule I-A shall be deemed modified to reflect the Commitments (and, if an assignment of all or any portion of the Canadian Commitment is being made, Schedule I-B shall be deemed modified to reflect the new
Canadian Lender) and/or outstanding Loans, as the case may be, of such new Lender and of the existing Lenders, (iii) upon the surrender of the relevant Notes by the assigning Lender (or, upon such assigning Lender’s indemnifying the
respective Borrower or Borrowers for any lost Note pursuant to a customary indemnification agreement) new Notes will be issued, at the relevant Borrower’s expense, to such new Lender and to the assigning Lender upon the request of such 

  

 -190- 








 
new Lender or assigning Lender, such new Notes to be in conformity with the requirements of Section 2.05 (with appropriate modifications) to the
extent needed to reflect the revised Commitments and/or outstanding Loans, as the case may be, (iv) except in the case of assignments made prior to the Syndication Date and as part of the primary syndication of the Loans and Commitments, so
long as no Event of Default then exists the consent of Aleris in each case shall be required in connection with any such assignment pursuant to clause (y) above (each of which consents shall not be unreasonably withheld or delayed),
(v) the consent of the Administrative Agent (or if an assignment of any Canadian Commitment or related outstandings, the Canadian Administrative Agent), each Swingline Lender and each Issuing Lender (for the respective Tranche) shall be
required in connection with any assignment of a Commitment to an Eligible Transferee pursuant to clause (y) above (which consents shall not be unreasonably withheld or delayed), (vi) the Administrative Agent shall receive at the time of
each such assignment, from the assigning or assignee Lender, the payment of a non-refundable assignment fee of $3,500, (vii) no such transfer or assignment will be effective until recorded by the Administrative Agent on the Register pursuant to
Section 13.15 and (viii) at the time of each assignment pursuant to this Section 13.04(b) to a Person which is not already a Lender hereunder (whether pursuant to clause (v) or (y) above), the respective
assignee shall have acknowledged in writing (which may be in the executed Assignment and Assumption Agreement) that it is bound by the terms of the Re-Allocation Agreement. To the extent of any assignment pursuant to this
Section 13.04(b), the assigning Lender shall be relieved of its obligations hereunder with respect to its assigned Commitments and outstanding Loans. At the time of each assignment pursuant to this Section 13.04(b) to a
Person which is not already a Lender hereunder (other than a Canadian Lender in its capacity solely as a Lender to the Canadian Borrowers), the respective assignee Lender shall, to the extent legally entitled to do so, provide to Aleris the
appropriate Internal Revenue Service Forms and necessary attachments (and, if applicable, a Section 5.04(b)(ii) Certificate) described in Section 5.04(b). At the time of each assignment pursuant to this Section 13.04(b)
to a Person which is not already a Canadian Lender hereunder, the respective assignee shall, to the extent legally entitled to do so, provide the documents required by Section 2.17(a) and shall, to the extent it is legally entitled to do so,
represent that it is a Canadian Resident. To the extent that prior to the occurrence of a Conversion Event an assignment of all or any portion of a Lender’s Commitments and related outstanding ABL Obligations pursuant to
Section 2.13 or this Section 13.04(b) would, at the time of such assignment, result in amounts payable under Section 2.10, 3.06 or 5.04 (other than excess costs paid in respect of Canadian Borrower
Obligations or European Borrower Obligations under Section 5.04 with respect to assignments effected when a Significant Event of Default exists, or after a Conversion Event has occurred) that exceed the respective amounts that would be
payable by the Borrowers at such time to the respective assigning Lender under such Sections in the absence of such assignment, then the Borrowers shall not be obligated to pay such excess amount (although the Borrowers, in accordance with and
pursuant to the other provisions of this Agreement, shall be obligated to pay any other excess amounts or increased costs of the type described above resulting from changes in any applicable law, treaty, governmental rule, regulation, guidelines or
order, or in the interpretation thereof, after the date of the respective assignment). 
 (c) In the event of an assignment or transfer of
U.S./European Commitments or under the U.S/European Tranche including Restricted Sub-Participations (but not including participations that are not Restricted Sub-Participations), so long as no Significant Event of Default then exists and no
Conversion Event has theretofore occurred, the assignee Lender shall 

  

 -191- 








 
make the representations in the Assignment and Assumption Agreement as to whether it is a Swiss Qualifying Bank on the effective date of the respective
assignment, and if it represents that it is a Swiss Qualifying Bank and if such assignee Lender is not incorporated in an OECD country at such time, so long as no Significant Event of Default then exists and no Conversion Event has theretofore
occurred, Aleris has the right prior to the transfer to request that such new Lender provide to it a written confirmation signed by the Swiss Federal Tax Administration that it is a bank as per explanatory note of the Swiss Federal Tax
Administration No. S-02.123(9.86) as amended from time to time. If the assignee Lender is not a Swiss Qualifying Bank and there is reasonable doubt as to whether such assignee Lender counts as one or several Lenders, Aleris has the right (unless a
Significant Event of Default then exists or a Conversion Event has theretofore occurred) prior to the transfer to request that such assignee Lender provide to it a written confirmation signed by the Swiss Federal Tax Administration that such
assignee Lender counts as one (or several, as the case may be) Swiss Non-Qualifying Bank. In the event that the respective assignee (or participant pursuant to a Restricted Sub-Participation) in respect of U.S./European Commitments (or related
outstandings to the European Borrower) is unable or unwilling to represent that it is a Swiss Qualifying Bank, then, unless a Significant Event of Default is in existence or a Conversion Event has occurred, the consent of the Administrative Agent
and Aleris shall be required to effect the respective assignment or Restricted Sub-Participation (which consents shall not be unreasonably withheld or delayed); provided that no such consent shall be given by Aleris if, after giving effect to the
respective assignment or Restricted Sub-Participation, the number of Lenders to the European Borrower or holders of Restricted Sub-Participations pursuant to extensions of credit to European Borrower under this Credit Agreement which are Swiss
Non-Qualifying Banks would exceed 10. 
 (d) Any Lender which enters into an assignment, transfer or Restricted Sub-Participation (but not
including (x) assignments effected in accordance with the relevant requirements of Sections 13.04(b) and (c), and (y) participations that are not Restricted Sub-Participations) of its U.S./European Commitment or any outstanding under the
U.S./European Tranche shall ensure that: 
 (i) the terms of such assignment, transfer or sub-participation agreement prohibit
the new Lender or sub-participant from entering into further assignment, transfer or sub-participation agreements (in relation to the rights between it and such Lender) and assigning or granting any interest over the assignment, transfer or
sub-participation agreement, except in each case to a person who is a Swiss Qualifying Bank; 
 (ii) the new Lender or
sub-participant enters into a unilateral undertaking in favor of each Lender and each Credit Party incorporated in Switzerland to abide by the terms included in the assignment, transfer or sub-participation agreement to reflect sub-clause
(i) above; 
 (iii) the terms of such assignment, transfer or sub-participation agreement oblige the new Lender or
sub-participant, in respect of any further assignment, transfer or sub-participation, assignment or grant, to include a term identical to the provisions of this Sections 13.04(c) and (d) mutatis mutandis, including a requirement
that any further new Lender or sub-participant, assignee or grantee enters into such undertaking; and 
  

 -192- 








 (iv) the identity of the new Lender or sub-participant is permitted to be disclosed to
the Swiss Federal Tax Administration by the European Borrower (if requested by the Swiss Federal Tax Administration to do so). 
 (e) Nothing
in this Agreement shall prevent or prohibit any Lender from pledging its Loans and Notes (other than Canadian Revolving Loans and/or Canadian Revolving 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 (e) shall release the
transferor Lender from any of its obligations hereunder. 
 13.05 No Waiver; Remedies Cumulative. No failure or delay on the part of
the Administrative Agent, the Collateral Agent, any Issuing Lender 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, any Issuing Lender 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, any Issuing Lender 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, any Issuing Lender or any Lender to any other or further action in any circumstances without notice or demand.

 13.06 Payments Pro Rata. (a) Except as otherwise provided in this Agreement, the Administrative Agent agrees that promptly
after its receipt of each payment from or on behalf of any Borrower in respect of any ABL Obligations hereunder, the Administrative Agent shall distribute such payment to the Lenders entitled thereto (other than any Lender that has consented in
writing to waive its pro rata share of any such payment) pro rata based upon their respective shares, if any, of the ABL Obligations with respect to which such payment was received. 
 (b) Each of the Lenders agrees that, if it should receive any amount hereunder (whether by voluntary payment, by realization upon security, by the
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,
Unpaid Drawings, Commitment Commission or Letter of Credit Fees, of a sum which with respect to the related sum or sums received by other Lenders is in a greater proportion than the total of such Obligation then owed and due to such Lender bears to
the total of such ABL Obligations then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for cash without

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

 -196- 








 
definition of Required Lenders or Supermajority Lenders (it being understood that, with the consent of the Required Lenders, additional extensions of credit

(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 each Issuing Lender, amend, modify or waive any provision of Section 3 or alter its rights or obligations with respect to Letters of Credit, (3) without the consent of
the Administrative Agent, amend, modify or waive any provision of Section 12 or any other provision of this Agreement as same relates to the rights or obligations of the Administrative Agent, (4) without the consent of the

as used therein) as such definitions are set forth herein on the Effective Date (or as same may be amended from time to time pursuant to this clause (7)) in a manner which would have the effect of increasing availability thereunder as
determined in good faith by the Administrative Agent or the Collateral Agent, (8) without the consent of the Supermajority Lenders, increase the percentage of the Borrowing Base for which Agent Advances may be made pursuant to
Section 2.01(f) or (9) without the consent of the Supermajority Lenders of the affected Tranche, amend, modify or waive any provision of this Agreement in a manner which would have a disproportionate effect on such Tranche (except
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 Effective Date). Notwithstanding
the foregoing, Schedules XVII, XVIII and XIX may be amended by the Administrative Agent and the Collateral Agent in their Permitted Discretion. 
 (b) If, in connection with any proposed change, waiver, discharge or termination of any of the provisions of this Agreement as contemplated by clauses (i) through (v), inclusive, of the first proviso to Section 13.12(a),
the consent of the Required Lenders is obtained but the consent of one or more of such other Lenders whose consent is required is not obtained, then Aleris shall have the right, so long as all non-consenting Lenders whose individual consent is
required are treated as described in either clauses (A) or (B) below, to either (A) subject to compliance with Sections 2.17 and 2.19, replace each such non-consenting Lender or 

  

 -197- 








 
Lenders (or, at the option of Aleris the respective Lender’s consent is required with respect to less than all Tranches of Loans (or related
Commitments), to replace only the respective Tranche of Commitments and/or Loans of the respective non-consenting Lender which 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, waiver, discharge or termination or (B) terminate each Tranche of such non-consenting Lender’s Commitment
(if such Lender’s consent is required as a result of such Tranche of its Commitment) and/or repay each Tranche of outstanding Loans of such Lender which gave rise to the need to obtain such Lender’s consent and/or cash collateralize its
applicable L/C Participation Percentage of the Letter of Credit Outstandings, in accordance with Sections 4.02(b) and/or 5.01(b), provided that, unless the Commitments that are terminated and Loans that are repaid pursuant to
preceding clause (B) are immediately replaced in full at such time through the addition of new Lenders or the increase of the Commitments and/or outstanding Loans of existing Lenders (who in each case must specifically consent thereto), then in
the case of any action pursuant to preceding clause (B) the Required Lenders (determined after giving effect to the proposed action) shall specifically consent thereto, provided further, that in any event Aleris shall not have the right
to replace a Lender, terminate its Commitments or repay its Loans solely as a result of the exercise of such Lender’s rights (and the withholding of any required consent by such Lender) pursuant to the second proviso to
Section 13.12(a). 
 13.13 Survival. All indemnities set forth herein including, without limitation, in
Sections 2.10, 2.11, 3.06, 5.04, 12.06 and 13.01 shall survive the execution, delivery and termination of this Agreement and the Notes and the making and repayment of the ABL Obligations. 
 13.14 Domicile of Loans. Each Lender may, subject to Sections 2.17 and 2.19, transfer and carry its Loans and/or participations in
outstanding Letters of Credit at, to or for the account of any office, Subsidiary or Affiliate of such Lender. Notwithstanding anything to the contrary contained herein, to the extent that a transfer of Loans and/or participations in outstanding
Letters of Credit pursuant to this Section 13.14 would, at the time of such transfer, result in amounts payable under Section 2.10, 2.11, 3.06 or 5.04 that exceed the amounts that would be payable by
Borrowers under such sections to the respective Lender prior to such transfer, then the Borrowers shall not be obligated to pay such increased costs (although the Borrowers shall be obligated to pay any other excess amounts of the type described
above resulting from changes in any applicable law, treaty, governmental rule, regulation, guidelines or order, or in the interpretation thereof, after the date of the respective transfer). 
 13.15 Register. Each Borrower hereby designates the relevant Administrative Agent to serve as its agent, solely for purposes of this
Section 13.15, to maintain a register (the “Register”) on which it will record the Commitments from time to time of each of the Lenders, the Loans made by each of the Lenders, the amount of any principal or interest due
and payable with respect to such Loans and each repayment in respect of the principal amount, and related interest amounts of the Loans of each Lender. Failure to make any such recordation, or any error in such recordation, shall not affect the
Borrowers’ obligations in respect of such Loans. With respect to any Lender, the transfer of the Commitments of such Lender and the rights to the principal of, and interest on, any Loan made pursuant to such Commitments shall not be effective
until such transfer is recorded on the Register maintained by the Administrative Agent 

  

 -198- 








 
with respect to ownership of such Commitments and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitments
and for Loans shall remain owing to the transferor. The registration of assignment or transfer of all or part of any Commitments and Loans shall be recorded by the Administrative Agent on the Register only upon the acceptance by the Administrative
Agent of a properly executed and delivered Assignment and Assumption Agreement pursuant to Section 13.04(b). Coincident with the delivery of such an Assignment and Assumption Agreement to the Administrative Agent for acceptance and
registration of assignment or transfer of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Lender shall surrender the Note (if any) evidencing such Loan, and thereupon one or more new Notes in the same
aggregate principal amount shall be issued to the assigning or transferor Lender and/or the new Lender at the request of any such Lender. The Borrowers jointly and severally agree to indemnify the Administrative Agent from and against any and all
losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 13.15. 
 13.16 Confidentiality. (a) Subject to the provisions of clause (b) of this Section 13.16, each Lender agrees that it will
use its reasonable efforts not to disclose without the prior consent of Aleris (other than to Affiliates of such Lender, its employees, auditors, advisors or counsel or to another Lender if such Lender or such Lender’s holding or parent company
in its reasonable discretion determines that any such party should have access to such information, provided such Persons shall be subject to the provisions of this Section 13.16 to the same extent as such Lender) any information with
respect to Aleris or any of its Subsidiaries which is now or in the future furnished pursuant to this Agreement or any other Credit Document and which is designated as confidential by Aleris, provided that any Lender may disclose any such
information (i) as has become generally available to the public other than by virtue of a breach of this Section 13.16(a) by the respective Lender, (ii) as may be required or appropriate in any report, statement or testimony
required to be submitted to any municipal, state or Federal regulatory body having or claiming to have jurisdiction over such Lender or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar organizations (whether in
the United States or elsewhere) or their successors, (iii) as may be required or appropriate in 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 13.16, and (vii) to any pledgee under Section 13.04(e) or any
prospective or actual transferee or participant in connection with any contemplated transfer or participation of any of the Notes or Commitments or any interest therein by such Lender, provided that such prospective transferee agrees to be
bound by the confidentiality provisions contained in this Section 13.16. 
 (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), provided such Persons shall be subject to the provisions of this Section 13.16 to the same extent as such Lender.

IN AN AGENCY CAPACITY PURSUANT TO THE TERM CREDIT AGREEMENT, AND EACH LENDER HEREBY IRREVOCABLY WAIVES ANY OBJECTION THERETO OR CAUSE OF ACTION ARISING
THEREFROM. 
 13.18 Aleris as Agent for the Borrowers. Each Borrower hereby irrevocably appoints Aleris as its agent and
attorney-in-fact for all purposes under this Agreement and each other Credit Document, which appointment shall remain in full force and effect unless and until the Administrative Agent shall have received prior written notice signed by the
respective appointing Borrower that such appointment has been revoked. Each Borrower hereby irrevocably appoints and authorizes Aleris (i) to provide the Administrative Agent with all notices with respect to Loans and Letters of Credit obtained
for the benefit of any Borrower and all other notices and instructions under this Agreement or any other Credit Document and (ii) to take such action as Aleris deems appropriate on its behalf to obtain Loans and Letters of Credit and to
exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement and the other Credit Documents. 
 13.19 Special Provisions Regarding Pledges of Equity Interests in, and Promissory Notes Owed by, Persons Not Organized in the United States. The parties hereto acknowledge and agree that the provisions of the various Security
Documents executed and delivered by the Credit Parties require that, among other things, all promissory notes executed by, and Equity Interests in, various Persons owned by the respective Credit Party be pledged, and delivered for pledge, pursuant
to the Security Documents. The parties hereto further acknowledge and agree that each Credit Party shall be required to take all actions under the laws of the jurisdiction in which such Credit Party is organized to create and perfect all security
interests granted pursuant to the various Security Documents and to take all actions under the laws of the United States, Canada, Switzerland, Germany, Belgium, France and England and any 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 Initial Borrowing Date, no actions have been required to be taken to perfect, under local law of the jurisdiction of the Person who issued the respective promissory notes or
whose Equity Interests are pledged, under the Security Documents. Aleris hereby agrees that, following any request by the Administrative Agent or Required Lenders to do so, Aleris shall, and shall cause its Subsidiaries to, take such actions under
the local law of any jurisdiction with respect to which such actions have not already been taken as are determined by the Administrative Agent or Required Lenders to be necessary or desirable in order to fully perfect, preserve or protect the
security interests granted pursuant to the various Security Documents under the laws of such jurisdictions. If requested to do so pursuant to this Section 13.19, all such actions shall be taken in accordance with the provisions of this
Section 13.19 and Section 9.12 and within the time periods set forth therein. All conditions and representations contained in this Agreement and the other Credit Documents shall be deemed modified to the extent necessary to
effect the foregoing and so that same are not violated by reason of the failure to take actions under local law (but only with respect to Equity Interest of, and promissory notes issued by, Persons organized under laws of jurisdictions other 

  

 -201- 








 
than the United States, Canada, Switzerland, Germany, Belgium, France and England and any State, province or territory thereof) not required to be taken in
accordance with the provisions of this Section 13.19, provided that to the extent any representation or warranty would not be true because the foregoing actions were not taken, the respective representation of warranties shall be
required to be true and correct in all material respects at such time as the respective action is required to be taken in accordance with the foregoing provisions of Section 9.12 and this Section 13.19. 
 13.20 Post-Closing Actions. Notwithstanding anything to the contrary contained in this Agreement or the other Credit Documents, the parties hereto
acknowledge and agree that: 
 (a) Aleris and its Subsidiaries were not required to have filed (or cause to have filed) on or
prior to the Initial Borrowing Date financing statements (Form UCC-1) or any filings with the United States Patent and Trademark Office or the United States Copyright Office necessary to perfect the security interest purported to be created by the
U.S. Security Agreement or the U.S. Pledge Agreement, as applicable. Not later than the 10th day after the Initial Borrowing Date, Aleris and its Subsidiaries shall have filed (or cause to have filed) all of such financing statements (Form UCC-1)
and any 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 XVI as promptly as
practicable, and in any event within the time periods set forth in Schedule XVI. The provisions of Schedule XVI 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 Initial Borrowing Date, the respective representation and warranty shall be required to be true and correct in all material respects at the time the respective action is taken (or was
required to be taken) in accordance with the foregoing provisions of this Section 13.20 and (y) all representations and warranties relating to the Security Documents shall be required to be true immediately after the actions
required to be taken by this Section 13.20 have been taken (or were required to be taken). The acceptance of the benefits of each Credit Event shall constitute a representation, warranty and covenant by Aleris to each of the Lenders that
the actions required pursuant to this Section 13.20 will be, or have been, taken within the relevant time periods referred to in this Section 13.20 and that, at such time, all representations and warranties contained in this
Agreement and the other Credit Documents shall then be true and correct without any modification pursuant to this Section 13.20, and the parties hereto acknowledge and agree that the failure to take any of the actions required above,
within the relevant time periods required above, shall give rise to an immediate Event of Default pursuant to this Agreement.

 13.21 The Patriot Act. Each Lender subject to the USA PATRIOT ACT (Title 111 of Pub. L. 107-56
(signed into law October 26, 2001)) (the “Patriot Act”) hereby notifies the Borrowers that pursuant to the requirements of the 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 Act. 
 13.22 Judgment Currency. (a) The Credit Parties’ obligations hereunder and under the other Credit Documents to make payments in any currency (the “Obligation Currency”) shall not be
discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by any
Agent or the respective Lender of the full amount of the Obligation Currency expressed to be payable to the such Agent or such Lender under this Agreement or the other Credit Documents. If for the purpose of obtaining or enforcing judgment against
any Credit Party in any court or in any jurisdiction, it becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the “Judgment Currency”) an
amount due in the Obligation Currency, the conversion shall be made at 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 or exchange prevailing on
the Judgment Currency Conversion Date. 
 (c) For purposes of determining any rate of exchange for this Section, such amounts shall include
any premium and costs payable in connection with the purchase of the Obligation Currency. 
 13.23 Release of Borrower. In the event
that all of the capital stock or other equity interests of one or more Borrowers (other than Aleris, the European Borrower or Aleris Canada) is sold or otherwise disposed of or liquidated in compliance with the requirements of
Section 10.02 (or such sale, other disposition or liquidation has been approved in writing by the Required Lenders (or all the Lenders if required by Section 13.12)) and the proceeds of such sale, disposition or liquidation
are applied in accordance with the provisions of this Agreement, to the extent applicable, such Borrower shall, upon consummation of such sale or other disposition (except to the extent that such sale or disposition is to Aleris or another
Subsidiary thereof), be released as a Borrower and a Guarantor under this Agreement and the other Credit Documents automatically and without further action and this Agreement shall, as to each such Borrower or Borrowers, terminate, and have no
further force or effect (it being understood and

agreed that the sale of one or more Persons that own, directly or indirectly, all of the capital stock or other equity interests of any Borrower (other than
Aleris, the European Borrower or Aleris Canada) shall be deemed to be a sale of such Borrower for the purposes of this Section 12.13). 
 13.24 Lender Acknowledgment. Each Lender acknowledges that it is subject to and bound by the Re-Allocation Agreement. The Re-allocation Agreement is an agreement solely amongst the Lenders (and their successors and assigns) and is
not an agreement to which Aleris or any of its Subsidiaries is party. As more fully provided therein, the Re-allocation Agreement can only be amended by the parties thereto in accordance with the provisions thereof. 
 13.25 European Sales Offices. Notwithstanding anything to the contrary contained herein, all of the Equity Interests of each of the Subsidiaries
of Corus Aluminium NV in existence on the Initial Borrowing Date (each, such Subsidiary, a “European Sales Office”) may be transferred to the European Borrower so long as (i) the respective European Sales Office owns no assets
other than de minimis assets and (ii) the respective European Sales Office has no operations other than the solicitation of sales of finished aluminum product to end-use customers by and on behalf of the European Borrower or the
Specified Manufacturing Subsidiaries, as permitted pursuant to this Agreement. 
 13.26 Abstract Acknowledgement 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 acknowledgement 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 Credit Documents as and when that amount falls due for payment under the relevant Credit Document 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 Credit Documents as such amount has become due and payable. 
 (c) The Collateral Agent has the independent right to demand and receive full or partial payment of the amounts payable by each Borrower under this
Section 13.26, irrespective of any discharge of such Borrower’s obligation to pay those amounts to the other Secured Creditors resulting from failure by them to take appropriate steps, in insolvency proceedings affecting such
Borrower, to preserve their entitlement to be paid those amounts. 
 (d) Any amount due and payable by a Borrower to the Collateral Agent
under this Section 13.26 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 Credit Documents 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 u;
provided that no Borrower may consider its obligations towards a Secured Creditor to be so 

  

 -204- 








 
discharged by virtue of any set-off, counterclaim or similar defence 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 Credit
Documents are several and are separate and independent from, and without prejudice to, the rights of the Collateral Agent to receive payment under this Section 13.26. 
 (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 Credit Documents. 
 13.27 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 acknowledgement of indebtedness pursuant to
Section 13.26 of this Agreement and all proceeds held by the Collateral Agent pursuant to or in connection with such abstract acknowledgement of indebtedness are held by the Collateral Agent with effect from the date of such abstract
acknowledgement of indebtedness in trust for the Secured Creditors and will 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 acknowledgement of indebtedness shall not increase the total amount of the Secured Obligations (as defined in the respective agreement governing German Security) and shall not result in any additional
liability of any of the Credit Parties or otherwise prejudice the rights of any of the Credit Parties. Accordingly, payment of the obligations under such abstract 

  

 -205- 








 
acknowledgement of indebtedness shall, to the same extent, discharge the corresponding Secured Obligations and vice versa. 
 SECTION 14. U.S. Borrower Guaranty. 
 14.01 Guaranty. In order to induce the Administrative Agent, the Collateral Agent, the Issuing Lenders and the Lenders to enter into this Agreement and to extend credit hereunder, and to induce the other Guaranteed Creditors to enter
into Interest Rate Protection Agreements, Currency Hedging Agreements and Treasury Services Agreements and in recognition of the direct benefits to be received by each U.S. Guarantor Party from the proceeds of the Loans, the issuance of the Letters
of Credit and the entering into of such Interest Rate Protection Agreements, Currency Hedging Agreements and Treasury Services Agreements, each U.S. Guarantor Party hereby agrees with the Guaranteed Creditors as follows: each U.S. Guarantor Party
hereby jointly and severally, unconditionally and irrevocably guarantees the full and prompt payment when due, whether upon maturity, acceleration or otherwise, of any and all of the Relevant Guaranteed Obligations to the Guaranteed Creditors. If
any or all of the Relevant Guaranteed Obligations to the Guaranteed Creditors becomes due and payable hereunder, each U.S. Guarantor Party, jointly and severally, unconditionally and irrevocably, promises to pay such indebtedness to the
Administrative Agent and/or the other Guaranteed Creditors, or order, on demand, together with any and all expenses which may be incurred by the Administrative Agent and the other Guaranteed Creditors in collecting any of the Relevant Guaranteed
Obligations. 
 14.02 Reinstatement. If 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 Guaranteed Obligations and any of the aforesaid payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property or (ii) any settlement or compromise of any such claim effected by such payee with any such claimant (including any Guaranteed Party), then and in such event each U.S. Guarantor Party agrees
that any such judgment, decree, order, settlement or compromise shall be binding upon such U.S. Guarantor Party, notwithstanding any revocation of this U.S. Borrower Guaranty or other instrument evidencing any liability of any other Guaranteed
Party, and such U.S. Guarantor Party shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such payee. 
 14.03 Bankruptcy. Additionally, each U.S. Guarantor Party jointly and severally, unconditionally and irrevocably guarantees the payment of any and
all of the Relevant Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by the Borrowers upon the occurrence of any of the events specified in Section 11.05, and irrevocably and unconditionally promises to
pay such indebtedness to the Guaranteed Creditors, or order, on demand, in lawful money of the United States. 
 14.04 Nature of
Liability. The liability of each U.S. Guarantor Party hereunder is primary, absolute and unconditional, exclusive and independent of any security for or other guaranty of the Relevant Guaranteed Obligations, whether executed by any other
guarantor or by any other party, and the liability of each U.S. Guarantor Party hereunder shall not be affected or 

  

 -206- 








 
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 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 Guaranteed Obligations which any such Guaranteed Creditor repays to any Guaranteed Party pursuant to court
order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each U.S. Guarantor Party waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding, or
(f) any action or inaction by the Guaranteed Creditors as contemplated in Section 14.06, or (g) any invalidity, irregularity or enforceability of all or any part of the Relevant Guaranteed Obligations or of any security
therefor. To the extent more than one U.S. Guarantor Party guarantees the same Relevant Guaranteed Obligations hereunder, the liabilities of such U.S. Guarantor Party with respect thereto shall be joint and several. 
 14.05 Independent Obligation. The obligations of each U.S. Guarantor Party hereunder are independent of the obligations of any other guarantor,
any other party or any Guaranteed Party, and a separate action or actions may be brought and prosecuted against each U.S. Guarantor Party whether or not action is brought against any other guarantor, any other party or any Guaranteed Party and
whether or not any other guarantor, any other party or any Guaranteed Party be joined in any such action or actions. Each U.S. Guarantor Party waives, to the fullest extent permitted by law, the benefit of any statute of limitations affecting its
liability hereunder or the enforcement thereof. Any payment by any Guaranteed Party or other circumstance which operates to toll any statute of limitations as to any Guaranteed Party shall operate to toll the statute of limitations as to each U.S.
Guarantor Party. 
 14.06 Authorization. Each U.S. Guarantor Party 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 Guaranteed Obligations (including any increase or decrease
in the principal amount thereof or the rate of interest or fees thereon), any security therefor, or any liability incurred directly or indirectly in respect thereof, and this U.S. Borrower Guaranty shall apply to the Relevant Guaranteed Obligations
as so changed, extended, renewed or altered; 
 (b) take and hold security for the payment of the Relevant 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 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;

  

 -207- 








 (d) release or substitute any one or more endorsers, guarantors, any Guaranteed Party or
other obligors; 
 (e) settle or compromise any of the Relevant Guaranteed Obligations, any security therefor or any liability
(including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of any Guaranteed Party to its creditors
other than the Guaranteed Creditors; 
 (f) apply any sums by whomsoever paid or howsoever realized to any liability or
liabilities of any Guaranteed Party to the Guaranteed Creditors regardless of what liability or liabilities of such Guaranteed Party remain unpaid; 
 (g) consent to or waive any breach of, or any act, omission or default under, this Agreement, any other Credit Document, any Interest Rate Protection Agreement, any Currency Hedging Agreement or any Treasury Services
Agreement or any of the instruments or agreements referred to herein or therein, or otherwise amend, modify or supplement this Agreement, any other Credit Document, any Interest Rate Protection Agreement, any Other Hedging Agreement or any Treasury
Services Agreement or any of such other instruments or agreements; and/or 
 (h) take any other action which would, under
otherwise applicable principles of common law, give rise to a legal or equitable discharge of such Borrower from its liabilities under this U.S. Borrower Guaranty. 
 14.07 Reliance. It is not necessary for any Guaranteed Creditor to inquire into the capacity or powers of any U.S. Guarantor Party or any of their respective Subsidiaries or the officers, directors, partners or
agents acting or purporting to act on their behalf, and any Relevant Guaranteed Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder. 
 14.08 Subordination. Any indebtedness of any Guaranteed Party now or hereafter owing to any Borrower is hereby subordinated to the Relevant
Guaranteed Obligations owing to the Guaranteed Creditors; and if the Administrative Agent so requests at a time when an Event of Default exists, all such indebtedness of any U.S. Guarantor Party to any Guaranteed Party shall be collected, enforced
and received by Aleris for the benefit of the Guaranteed Creditors and be paid over to the Administrative Agent on behalf of the Guaranteed Creditors on account of the Relevant Guaranteed Obligations to the Guaranteed Creditors, but without
affecting or impairing in any manner the liability of such U.S. Guarantor Party under the other provisions of this U.S. Borrower Guaranty. Prior to the transfer by any U.S. Guarantor Party of any note or negotiable instrument evidencing any such
indebtedness of any Guaranteed Party to such U.S. Guarantor Party, such U.S. Guarantor Party shall mark such note or negotiable instrument with a legend that the same is subject to this subordination. Without limiting the generality of the
foregoing, each U.S. Guarantor Party hereby agrees with the Guaranteed Creditors that it will not exercise any right of subrogation which it may at any time otherwise have as a result of this U.S. Borrower Guaranty (whether contractual, under
Section 509 of the 

  

 -208- 








 
Bankruptcy Code or otherwise) until all Relevant Guaranteed Obligations have been irrevocably paid in full in cash. 
 14.09 Waiver. (a) Each U.S. Guarantor Party waives any right (except as shall be required by applicable statute and cannot be waived) to
require any Guaranteed Creditor to (i) proceed against any Guaranteed Party, any other guarantor or any other party, (ii) proceed against or exhaust any security held from any Guaranteed Party, any other guarantor or any other party or
(iii) pursue any other remedy in any Guaranteed Creditor’s power whatsoever. Each U.S. Guarantor Party waives any defense based on or arising out of any defense of any Guaranteed Party, any other guarantor or any other party, other than
payment of the Relevant Guaranteed Obligations to the extent of such payment, based on or arising out of the disability of any Guaranteed Party, any U.S. Guarantor Party, any other guarantor or any other party, or the validity, legality or
unenforceability of the Relevant 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 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 any U.S. Guarantor Party hereunder except to the extent the Relevant Guaranteed Obligations have been paid. Each U.S. Guarantor Party waives any defense arising out of any such election by the
Guaranteed Creditors, even though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of such U.S. Guarantor Party against any Guaranteed Party or any other party or any security.

 (b) Each U.S. Guarantor Party 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 Guaranteed Obligations. Each U.S. Guarantor Party
assumes all responsibility for being and keeping itself informed of each Guaranteed Party’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Relevant Guaranteed Obligations and the
nature, scope and extent of the risks which such U.S. Guarantor Party assumes and incurs hereunder, and agrees that neither the Administrative Agent nor any of the other Guaranteed Creditors shall have any duty to advise such U.S. Guarantor Party of
information known to them regarding such circumstances or risks. 
 (c) Each U.S. Guarantor Party hereby acknowledges and affirms that it
understands that to the extent any Relevant Guaranteed Obligations are secured by Real Property located in the State of California, such U.S. Guarantor 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 such U.S. Guarantor Party’s or any Guaranteed Creditor’s right to proceed against any Borrower or any other guarantor of the Relevant Guaranteed Obligations. 

 

 -209- 








 (d) Each U.S. Guarantor Party hereby waives, to the fullest extent permitted by applicable law, all
rights and benefits under Sections 580a, 580b, 580d and 726 of the California Code of Civil Procedure. Each U.S. Guarantor Party hereby further waives, to the fullest extent permitted by applicable law, without limiting the generality of the
foregoing or any other provision hereof, all rights and benefits which might otherwise be available to such U.S. Guarantor Party 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 Guaranteed Obligations have been paid in full in cash, each U.S. Guarantor Party agrees that it will
not exercise its rights of subrogation and reimbursement and any other rights and defenses available to such U.S. Guarantor Party by reason of Sections 2787 to 2855, inclusive, of the California Civil Code, including, without limitation,
(1) any defenses such U.S. Guarantor Party may have to this U.S. Borrower Guaranty by reason of an election of remedies by the Guaranteed Creditors and (2) any rights or defenses such U.S. Guarantor Party may have by reason of protection
afforded to a Borrower pursuant to the antideficiency or other laws of California limiting or discharging such Borrower’s indebtedness, including, without limitation, Sections 580a, 580b, 580d and 726 of the California Code of Civil Procedure.
In furtherance of such provisions, such U.S. Guarantor Party 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
such U.S. Guarantor Party’s rights of subrogation and reimbursement against a Borrower by the operation of Section 580d of the California Code of Civil Procedure or otherwise. 
 (f) Each U.S. Guarantor Party warrants and agrees that each of the waivers set forth above is made with full knowledge of its significance and
consequences and that if any of such waivers are determined to be contrary to any applicable law or public policy, such waivers shall be effective only to the maximum extent permitted by law. 
 14.10 Maximum Liability. It is the desire and intent of each U.S. Guarantor Party and the Guaranteed Creditors that this U.S. Borrower Guaranty
shall be enforced against each U.S. Guarantor Party to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. If, however, and to the extent that, the obligations of any U.S.
Guarantor Party under this U.S. Borrower Guaranty shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers),
then the amount of each U.S. Guarantor Party’s obligations under this U.S. Borrower Guaranty shall be deemed to be reduced and such U.S. Guarantor Party shall pay the maximum amount of the Relevant Guaranteed Obligations which would be
permissible under applicable law. 
  

 -210- 








 SECTION 15. Nature of U.S. Borrower Obligations; Limitation on Canadian Borrower Obligations and
European Borrower Obligations. 
 15.01 Nature of U.S. Borrower Obligations and Canadian Borrower Obligations. Notwithstanding
anything to the contrary contained elsewhere in this Agreement, it is understood and agreed by the various parties to this Agreement that 
 (i) all U.S. Borrower Obligations to repay principal of, interest on, and all other amounts with respect to, all U.S./European Revolving Loans, Letter of Credit Outstandings and all other U.S. Borrower Obligations
pursuant to this Agreement and under any U.S. Borrower Revolving Note (including, without limitation, all fees, indemnities, taxes and other U.S. Borrower Obligations in connection therewith or in connection with the related Commitments) shall
constitute the joint and several obligations of each of the U.S. Borrowers. In addition to the direct (and joint and several) obligations of the U.S. Borrowers with respect to U.S. Borrower Obligations as described above, all such U.S. Borrower
Obligations shall be guaranteed pursuant to, and in accordance with the terms of, the U.S. Borrower Guaranty and the U.S. Subsidiaries Guaranty; and 
 (ii) all Canadian Borrower Obligations to repay principal of, interest on, and all other amounts with respect to, all Canadian Revolving Loans and all other Canadian Borrower Obligations pursuant to this Agreement and
under any Canadian Revolving Note (including, without limitation, all fees, indemnities, taxes and other Canadian Borrower Obligations in connection therewith or in connection with the related Commitments) shall constitute the joint and several
obligations of each of the Canadian Borrowers. In addition to the direct (and joint and several) obligations of the Canadian Borrowers with respect to Canadian Borrower Obligations as described above, all such Canadian Borrower Obligations shall be
guaranteed pursuant to, and in accordance with the terms of, the Canadian Subsidiaries Guaranty, the Canadian Parent Guaranty and the U.S. Subsidiaries Guaranty. 
 15.02 Independent Obligation. The obligations of each U.S. Borrower with respect to the U.S. Borrower Obligations are independent of the obligations of each other U.S. Borrower or any Guarantor under its
guaranty of such U.S. Borrower Obligations, and a separate action or actions may be brought and prosecuted against each U.S. Borrower, whether or not any other U.S. Borrower or any such Guarantor is joined in any such action or actions. Each U.S.
Borrower waives, to the fullest extent permitted by law, the benefit of any statute of limitations affecting its liability hereunder or the enforcement thereof. Any payment by any U.S. Borrower or other circumstance which operates to toll any
statute of limitations as to any U.S. Borrower shall, to the fullest extent permitted by law, operate to toll the statute of limitations as to each U.S. Borrower. 
 15.03 Authorization. Each of the U.S. Borrowers authorizes the Administrative Agent and the Lenders without notice or demand (except as shall be required by applicable statute and cannot be waived), and without
affecting or impairing its liability hereunder, from time to time to: 
 (a) exercise or refrain from exercising any rights
against any other U.S. Borrower or any Guarantor or others or otherwise act or refrain from acting; 
 (b) release or
substitute any other U.S. Borrower, endorsers, Guarantors or other obligors; 
  

 -211- 








 (c) settle or compromise any of the U.S. Borrower Obligations of any other U.S. Borrower
or any other Credit Party, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any
liability (whether due or not) of any U.S. Borrower to its creditors other than the Lenders; 
 (d) apply any sums paid by any
other U.S. Borrower or any other Person, howsoever realized or otherwise received to or for the account of such U.S. Guarantor Party to any liability or liabilities of such other U.S. Borrower or other Person regardless of what liability or
liabilities of such other Borrower or other Person remain unpaid; and/or 
 (e) consent to or waive any breach of, or act,
omission or default under, this Agreement or any of the instruments or agreements referred to herein, or otherwise, by any other Borrower or any other Person. 
 15.04 Reliance. It is not necessary for the Administrative Agent or any other Lender to inquire into the capacity or powers of any U.S. Borrower or any of its Subsidiaries or the officers, directors, members,
partners or agents acting or purporting to act on its behalf, and any U.S. Borrower Obligations made or created in reliance upon the professed exercise of such powers shall constitute the joint and several obligations of the U.S. Borrowers
hereunder. 
 15.05 Contribution; Subrogation. No U.S. Borrower shall have any rights of contribution or subrogation with respect to
any other U.S. Borrower as a result of payments made by it hereunder, in each case unless and until the Total Commitment has been terminated and all U.S. Borrower Obligations have been paid in full. 
 15.06 Waiver. Each U.S. Borrower waives any right to require the Administrative Agent or the other Lenders to (i) proceed against any other
U.S. Borrower, any Guarantor or any other party, (ii) proceed against or exhaust any security held from any U.S. Borrower, any Guarantor or any other party or (iii) pursue any other remedy in the Administrative Agent’s or the
Lenders’ power whatsoever. Each U.S. Borrower waives any defense based on or arising out of suretyship or any impairment of security held from any U.S. Borrower, any Guarantor or any other party or on or arising out of any defense of any other
U.S. Borrower, any Guarantor or any other party other than payment in full in cash of the U.S. Borrower Obligations, including, without limitation, any defense based on or arising out of the disability of any other U.S. Borrower, any Guarantor or
any other party, or the unenforceability of the U.S. Borrower Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any other U.S. Borrower, in each case other than as a result of the payment in full in
cash of the U.S. Borrower Obligations. 
 15.07 Limitation on Canadian Borrower Obligations and European Borrower Obligations.
Notwithstanding anything to the contrary herein or in any other Credit Document (including provisions that may override any other provision), in no event shall the Canadian Borrowers or any other Canadian Subsidiary of any Borrower or the European
Borrower or any other European Distribution Subsidiary of any Borrower guarantee or be deemed to have guaranteed or become liable or obligated on a joint and several basis or otherwise for, or to have 

  

 -212- 








 
pledged any of its assets to secure, any Obligation of a U.S. Borrower under this Agreement or any of the other Credit Documents (other than any such
Obligation of a U.S. Borrower as a guarantor of direct ABL Obligations of the Canadian Borrowers (in the case of the Canadian Borrowers or their Subsidiaries) or the European Borrower (in the case of the European Borrower or its Subsidiaries)). All
provisions contained in any Credit Document shall be interpreted consistently with this Section 15.07 to the extent possible, and where such other provisions conflict with the provisions of this Section 15.07, the provisions
of this Section 15.07 shall govern. 
 15.08 Limited Recourse Against Corus Aluminium Inc. Notwithstanding the fact that,
as the general partner of Corus LP, Corus Aluminium Inc. is jointly and severally liable with Corus LP for all of Corus LP’s obligations and liabilities provided for herein and under the other Credit Documents, any recourse against Corus
Aluminium Inc. pursuant to this Agreement or any other Credit Document, including without limitation the Canadian Security Agreements, shall be limited exclusively to the assets of Corus LP and the assets of Corus Aluminium Inc. held or owned by it
as general partner for and on behalf of Corus LP and there shall be no recourse against other assets of Corus Aluminium Inc. 
 SECTION 16.
U.S./European Revolving Loans; Intra-Lender Issues. 
 16.01 Specified Foreign Currency Participations. Notwithstanding
anything to the contrary contained herein, all U.S./European Revolving Loans which are denominated in Euros, Swiss Francs, Pounds Sterling and any other Available Currency agreed by DBNY (each, a “Specified Foreign Currency Loan”)
shall be made solely by the U.S./European Lenders who are Participating Specified Foreign Currency Lenders (as defined below). Each U.S./European Lender acceptable to DBNY that does not have Specified Foreign Currency Funding Capacity (a
“Participating Specified Foreign Currency Lender”) shall irrevocably and unconditionally purchase and acquire and shall be deemed to irrevocably and unconditionally purchase and acquire from DBNY, and DBNY shall sell and be deemed
to sell to each such Participating Specified Foreign Currency Lender, without recourse or any representation or warranty whatsoever, an undivided interest and participation (a “Specified Foreign Currency Participation”) in each
U.S./European Revolving Loan which is a Specified Foreign Currency Loan funded by DBNY in an amount equal to such Participating Specified Foreign Currency Lender’s U.S./European Percentage of the Borrowing that includes such U.S./European
Revolving Loan. Such purchase and sale of a Specified Foreign Currency Participation shall be deemed to occur automatically upon the making of a Specified Foreign Currency Loan by DBNY, without any further notice to any Participating Specified
Foreign Currency Lender. The purchase price payable by each Participating Specified Foreign Currency Lender to DBNY for each Specified Foreign Currency Participation purchased by it from DBNY shall be equal to 100% of the principal amount of such
Specified Foreign Currency Participation (i.e., the product of (i) the amount of the Borrowing that includes the relevant U.S./European Revolving Loan and (ii) such Participating Specified Foreign Currency Lender’s
U.S./European Percentage), and such purchase price shall be payable by each Participating Specified Foreign Currency Lender to DBNY in accordance with the settlement procedure set forth in Section 16.02 below. DBNY and the Administrative
Agent shall record on their books the amount of the U.S./European Revolving Loans made by DBNY and each Participating Specified Foreign Currency Lender’s 

  

 -213- 








 
Specified Foreign Currency Participation and Funded Specified Foreign Currency Participation therein, all payments in respect thereof and interest accrued
thereon and all payments made by and to each Participating Specified Foreign Currency Lender pursuant to this Section 16.01. 
 16.02 Settlement Procedures for Specified Foreign Currency Participations. Each Participating Specified Foreign Currency Lender’s Specified Foreign Currency Participation in the Specified Foreign Currency Loans shall be in an
amount equal to its U.S./European Percentage of all such Specified Foreign Currency Loans. However, in order to facilitate the administration of the Specified Foreign Currency Loans made by DBNY and the Specified Foreign Currency Participations,
settlement among DBNY and the Participating Specified Foreign Currency Lenders with regard to the Participating Specified Foreign Currency Lenders’ Specified Foreign Currency Participations shall take place in accordance with the following
provisions: 
 (i) DBNY and the Participating Specified Foreign Currency Lenders shall settle (a “Specified Foreign
Currency Participation Settlement”) by payments in respect of the Specified Foreign Currency Participations as follows: So long as any Specified Foreign Currency Loans are outstanding, Specified Foreign Currency Participation Settlements
shall be effected upon the request of DBNY through the Administrative Agent on such Business Days as requested by DBNY and as the Administrative Agent shall specify by a notice by telecopy, telephone or similar form of notice to each Participating
Specified Foreign Currency Lender requesting such Specified Foreign Currency Participation Settlement (each such date on which a Specified Foreign Currency Participation Settlement occurs herein called a “Specified Foreign Currency
Participation Settlement Date”), such notice to be delivered no later than 2:00 p.m. (New York time) at least one Business Day prior to the requested Specified Foreign Currency Participation Settlement Date; provided that DBNY shall
have the option but not the obligation to request a Specified Foreign Currency Participation Settlement Date and, in any event, shall not request a Specified Foreign Currency Participation Settlement Date prior to the occurrence of an Event of
Default; provided further, that if (x) such Event of Default is cured or waived in writing in accordance with the terms hereof, (y) no ABL Obligations have yet been declared due and payable under Article 11 and (z) the
Administrative Agent has actual knowledge of such cure or waiver, all prior to the Administrative Agent’s giving notice to the Participating Specified Foreign Currency Lenders of the first Specified Foreign Currency Participation Settlement
Date under this Agreement, then the Administrative Agent shall not give notice to the Participating Specified Foreign Currency Lenders of a Specified Foreign Currency Participation Settlement Date based upon such cured or waived Event of Default. If
on any Specified Foreign Currency Participation Settlement Date the total principal amount of the Specified Foreign Currency Loans made or deemed made by DBNY during the period ending on (but excluding) such Specified Foreign Currency Participation
Settlement Date and commencing on (and including) the immediately preceding Specified Foreign Currency Participation Settlement Date (or the Initial Borrowing Date in the case of the period ending on the first Specified Foreign Currency
Participation Settlement Date) (each such period herein called a “Specified Foreign Currency Participation Settlement Period”) is greater than the principal amount of Specified Foreign Currency Loans repaid during such Specified
Foreign Currency Participation Settlement Period to DBNY, each 

  

 -214- 








 
Participating Specified Foreign Currency Lender shall pay to DBNY (through the Administrative Agent), no later than 11:00 A.M. (New York time) on such
Specified Foreign Currency Participation Settlement Date, an amount equal to such Participating Specified Foreign Currency Lender’s ratable share of the amount of such excess. If in any Specified Foreign Currency Participation Settlement Period
the outstanding principal amount of the Specified Foreign Currency Loans repaid to DBNY in such period exceeds the total principal amount of the Specified Foreign Currency Loans made or deemed made by DBNY during such period, DBNY shall pay to each
Participating Specified Foreign Currency Lender (through the Administrative Agent) on such Specified Foreign Currency Participation Settlement Date an amount equal to such Participating Specified Foreign Currency Lender’s ratable share of such
excess. Specified Foreign Currency Participation Settlements in respect of Specified Foreign Currency Loans shall be made in the respective Available Currency in which such Specified Foreign Currency Loan was funded on the Specified Foreign Currency
Participation Settlement Date for such Specified Foreign Currency Loans. 
 (ii) If any Participating Specified Foreign
Currency Lender fails to pay to DBNY on any Specified Foreign Currency Participation Settlement Date the full amount required to be paid by such Participating Specified Foreign Currency Lender to DBNY on such Specified Foreign Currency Participation
Settlement Date in respect of such Participating Specified Foreign Currency Lender’s Specified Foreign Currency Participation (such Participating Specified Foreign Currency Lender’s “Specified Foreign Currency Participation
Settlement Amount”) with DBNY, DBNY shall be entitled to recover such unpaid amount from such Participating Specified Foreign Currency Lender, together with interest thereon (in the same respective currency or currencies as the relevant
Specified Foreign Currency Loans) at the Base Rate plus 2.00%. Without limiting DBNY’s rights to recover from any Participating Specified Foreign Currency Lender any unpaid Specified Foreign Currency Participation Settlement Amount
payable by such Participating Specified Foreign Currency Lender to DBNY, the Administrative Agent shall also be entitled to withhold from amounts otherwise payable to such Participating Specified Foreign Currency Lender an amount equal to such
Participating Specified Foreign Currency Lender’s unpaid Specified Foreign Currency Participation Settlement Amount owing to DBNY and apply such withheld amount to the payment of any unpaid Specified Foreign Currency Participation Settlement
Amount owing by such Participating Specified Foreign Currency Lender to DBNY. 
 If any Specified Foreign Currency Loans convert to U.S.
Dollars pursuant to Section 2.14, a Specified Foreign Currency Participation Settlement Date shall be deemed to automatically occur on the date of such conversion and DBNY shall receive an amount expressed in the respective Available
Currency immediately prior to such conversion. 
 16.03 Obligations Irrevocable. The obligations of each Participating Specified
Foreign Currency Lender to purchase from DBNY a participation in each Specified Foreign Currency Loan made by DBNY and to make payments to DBNY with respect to such participation, in each case as provided herein, shall be irrevocable and not subject
to any qualification or exception whatsoever, including any of the following circumstances: 
 (i) any lack of validity or
enforceability of this Agreement or any of the other Credit Documents or of any Loans, against the Borrowers or any other Credit Party; 
  

 -215- 








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

 (v) the occurrence of any Default or Event of Default; 
 (vi) the commencement or pendency of any events specified in Section 11.05, in respect of the Borrowers or any of its
Subsidiaries or any other Person; or 
 (vii) the failure to satisfy the applicable conditions precedent set forth in
Section 6 or 7. 
 16.04 Recovery or Avoidance of Payments. In the event any payment by or on behalf of any
Borrower or any other Credit Party received by the Administrative Agent with respect to any Specified Foreign Currency Loan made by DBNY is thereafter set aside, avoided or recovered from the Administrative Agent in connection with any insolvency
proceeding or due to any mistake of law or fact, each Participating Specified Foreign Currency Lender shall, upon written demand by the Administrative Agent, pay to DBNY (through the Administrative Agent) such Participating Specified Foreign
Currency Lender’s U.S./European Percentage of such amount set aside, avoided or recovered, together with interest at the rate and in the currency required to be paid by DBNY or the Administrative Agent upon the amount required to be repaid by
it. 
 16.05 Indemnification by Lenders. Each Participating Specified Foreign Currency Lender agrees to indemnify DBNY (to the extent
not reimbursed by the Borrowers and without limiting the obligations of the Borrowers hereunder or under any other Credit Document) ratably for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including attorneys’ fees) or disbursements of any kind and nature whatsoever that may be imposed on, incurred by or asserted against DBNY in any way relating to or arising out of any Specified Foreign Currency Loans or any action
taken or omitted by DBNY in connection therewith; provided that no Participating Specified Foreign Currency Lender shall be liable for any of the foregoing to the extent it arises from the gross negligence or willful misconduct of DBNY (as
determined by a court of competent jurisdiction in a final non-appealable judgment). Without limiting the foregoing, each Participating Specified Foreign Currency Lender agrees to reimburse DBNY promptly upon demand for such Participating Specified
Foreign Currency Lender’s ratable share of any costs or expenses payable by the Borrowers to DBNY in respect of the Specified Foreign Currency Loans to the extent that 

  

 -216- 








 
DBNY is not promptly reimbursed for such costs and expenses by the Borrowers. The agreement contained in this Section 16.05 shall survive payment
in full of all Specified Foreign Currency Loans. 
 16.06 Specified Foreign Currency Loan Participation Fee. In consideration for each
Participating Specified Foreign Currency Lender’s participation in the Specified Foreign Currency Loans made by DBNY, DBNY agrees to pay to the Administrative Agent for the account of each Participating Specified Foreign Currency Lender, as and
when DBNY receives payment of interest on its Specified Foreign Currency Loans, a fee (the “Specified Foreign Currency Participation Fee”) at a rate per annum equal to the Applicable Margin on such Specified Foreign Currency Loans
minus 0.25% on the Unfunded Specified Foreign Currency Participation of such Participating Specified Foreign Currency Lender in such Specified Foreign Currency Loans of DBNY. The Specified Foreign Currency Participation Fee in respect of any
unfunded Specified Foreign Currency Participation in a Specified Foreign Currency Loan shall be payable to the Administrative Agent in the Available Currency in which the respective Specified Foreign Currency Loan was funded when interest on such
Specified Foreign Currency Loan is received by DBNY. If DBNY does not receive payment in full of such interest, the Specified Foreign Currency Participation Fee in respect of the unfunded Specified Foreign Currency Participation in such Specified
Foreign Currency Loans shall be reduced proportionately. Any amounts payable under this Section 16.06 by the Administrative Agent to the Participating Specified Foreign Currency Lenders shall be paid in the Available Currency in which
the respective Specified Foreign Currency Loan was funded (or, if different, the currency in which such interest payments are actually received).
