 ARTICLE II 
 THE CREDITS 
 SECTION 2.01. Commitments. (a) Subject to the terms and conditions
and relying upon the representations and warranties herein set forth, each U.S. Lender agrees, severally and not jointly, to make term loans in dollars (the “U.S. Loans”) on the Tender Funding Date and thereafter from time to time
during the Credit Period to one or more of the Borrowers in accordance with the terms hereof; provided, however, that (i) after giving effect to any U.S. Loan, the aggregate principal amount of the outstanding U.S. Loans shall not
exceed the U.S. Commitments and (iii) at all times the aggregate principal amount of all outstanding U.S. Loans made by each U.S. Lender shall equal its Ratable Portion of the aggregate principal amount of all outstanding U.S. Loans. The U.S.
Commitment of each U.S. Lender is set forth on Schedule 2.01 to this Agreement under the caption “U.S. Commitments” or in any applicable Assignment and Assumption. Such U.S. Commitment may be terminated or reduced from time to time
pursuant to Section 2.10 or terminated pursuant to Article VII. Amounts of U.S. Loans prepaid or repaid may not be reborrowed. 
 (b)
Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Canadian/U.S. Lender agrees, severally and not jointly, to make term loans in dollars (the “Canadian/U.S. Loans”) on the
Tender Funding Date and thereafter from time to time during the Credit Period to one or more of the Borrowers in accordance with the terms hereof; provided, however, that (i) after giving effect to any Canadian/U.S. Loan, the
aggregate principal amount of the outstanding Canadian/U.S. Loans shall not exceed the Canadian/U.S. Commitments and (ii) at all times the aggregate principal amount of all outstanding Canadian/U.S. Loans made by each Canadian/U.S. Lender shall
equal its Ratable Portion of the aggregate principal amount of all outstanding Canadian/U.S. Loans. The Canadian/U.S. Commitment of each Canadian/U.S. Lender is set forth on Schedule 2.01 to this Agreement under the caption “Canadian/U.S.
Commitments” or in any applicable Assignment and Assumption. Such Canadian/U.S. Commitment may be terminated or reduced from time to time pursuant to Section 2.10 or terminated pursuant to Article VII. Amounts of Canadian/U.S. Loans
prepaid or repaid may not be reborrowed. 
 SECTION 2.02. Loans. (a) Each Loan shall be made as part of a Borrowing consisting of
Loans made by the Lenders ratably in accordance with their respective applicable Commitments; provided, however, that the failure of any Lender to make any Loan shall not in itself relieve any other Lender of its obligation to lend
hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to make any Loan required to be made by such other Lender). The Loans comprising each Borrowing shall be in an aggregate principal
amount which is an integral multiple of $1,000,000 and not less than $50,000,000 (or an aggregate principal amount equal to the remaining balance of the applicable Commitments, as the case may be). 
 (b) Each Borrowing shall be comprised entirely of LIBOR Loans, U.S. Base Rate Loans or Canadian Base Rate Loans, as the applicable Borrower may request
pursuant to Section 2.03. Each Lender may at its option fulfill its Commitment with respect to any Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided, however, that any exercise
of such option shall not affect the obligation of the applicable Borrower to repay such Loan in accordance with the terms of this Agreement. Borrowings of more than one Type may be outstanding at the same time; provided, however, that
no Borrower shall be entitled to request any Borrowing which, if made, would result in an aggregate of more than twenty separate LIBOR Loans of any Lender being made to the Borrowers and outstanding under this Agreement at any one time. For purposes
of the foregoing, Loans having different Interest Periods, regardless of whether they commence on the same date, shall be considered separate Loans. 
  

 19 








 (c) Each Lender shall make each Loan that is (A) a Base Rate Loan or (B) a LIBOR Loan to be
made by it hereunder on the proposed date thereof by wire transfer of immediately available funds to the Administrative Agent in New York, New York, not later than 2:00 p.m., New York City time, and the Administrative Agent shall by 4:00 p.m., New
York City time, credit the amounts so received to the general deposit account of the Borrower to which such Loan is to be made with Mellon Bank, N.A., or such other account as such Borrower may designate in a written notice to the Administrative
Agent, or, if such Loans are not made on such date because any condition precedent to a Borrowing herein specified shall not have been met, return the amounts so received to the respective Lenders. Unless the Administrative Agent shall have received
notice from a Lender prior to the time of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in accordance with this paragraph (c) and the Administrative Agent may, in reliance upon such assumption, make available to the applicable Borrower on such date a corresponding
amount. If and to the extent that such Lender shall not have made such portion available to the Administrative Agent, such Lender and the applicable Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount is made available to such Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of such Borrower, the interest rate applicable
at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, a rate determined by the Administrative Agent to represent its cost of overnight or short-term funds (which determination shall be conclusive absent
manifest error). If such Lender shall repay to the Administrative Agent such corresponding amount, such amount shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement. 
 (d) Notwithstanding any other provision of this Agreement, no Borrower shall be entitled to request any Borrowing if the Interest Period requested with
respect thereto would end after the Scheduled Maturity Date. 
 SECTION 2.03. Notice of Borrowings. In order to request a Borrowing, a
Borrower shall give written or telecopy notice (or telephone notice promptly confirmed in writing or by telecopy) (a) in the case of a U.S. Base Rate Borrowing, to the Administrative Agent not later than 12:00 noon, New York City time, on the
Business Day of such proposed Borrowing, (b) in the case of a Canadian Base Rate Borrowing, to the Administrative Agent not later than 10:00 a.m., New York City time, one Business Day before such proposed Borrowing, or (c) in the case of a
LIBOR Borrowing, to the Administrative Agent not later than 10:00 a.m., New York City time, three Business Days before such proposed Borrowing. Such notice shall be irrevocable and shall in each case refer to this Agreement, identify the applicable
Borrower and specify (i) whether such Borrowing is to be made under the U.S. Facility or the Canadian/U.S. Facility; (ii) whether such Borrower is a Canadian Borrower or a U.S. Borrower; (iii) whether such Borrowing is to be a LIBOR
Borrowing or a Base Rate Borrowing; (iv) the date of such Borrowing (which shall be a Business Day) and the amount thereof; and (v) if such Borrowing is to be a LIBOR Borrowing, the Interest Period with respect thereto. If no election as
to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be (x) in the case of Loans to Borrowers other than Canadian Borrowers, a U.S. Base Rate Borrowing and (y) in the case of Canadian/U.S. Loans to a
Canadian Borrower, a Canadian Base Rate Borrowing. If no Interest Period with respect to any LIBOR Borrowing is specified in any such notice, then the Borrower giving the notice of Borrowing shall be deemed to have selected an Interest Period of one
month’s duration. The Administrative Agent shall promptly advise the Lenders of any notice given pursuant to this Section 2.03 and of each Lender’s portion of the requested Borrowing. 
  

 20 








 SECTION 2.04. Interest Elections. (a) Subject to the terms and conditions set forth in this
Agreement, at the option of the applicable Borrower, (x) all Loans to Borrowers other than Canadian Borrowers shall be made as U.S. Base Rate Loans or LIBOR Loans, (y) all Canadian/U.S. Loans to a Canadian Borrower shall be made as
Canadian Base Rate Loans or LIBOR Loans. Each Borrowing initially shall be of the Type specified in the applicable Borrowing request and, in the case of a LIBOR Borrowing, shall have an initial Interest Period as specified in such Borrowing request.
Thereafter, the applicable Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing in its existing Type and, in the case of a LIBOR Borrowing, may elect Interest Periods therefor, all as provided in this
Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing (each an “Interest Election Request”). 
 (b) To make
an Interest Election Request, the applicable Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing request would be required under Section 2.03 if such Borrower were requesting a Borrowing of
the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of
a written Interest Election Request signed by the Borrower. 
 (c) Each telephonic and written Interest Election Request shall specify the
following information in compliance with Sections 2.02 and 2.03: 
 (i) the Borrowing to which such Interest Election Request applies and, if
different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall
be specified for each resulting Borrowing); 
 (ii) the effective date of the election made pursuant to such Interest Election Request, which
shall be a Business Day; 
 (iii) whether the resulting Borrowing is to be a Base Rate Borrowing or a LIBOR Borrowing; and 
 (iv) if the resulting Borrowing is a LIBOR Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a
period contemplated by the definition of the term “Interest Period”. 
 If any such Interest Election Request requests a
LIBOR Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
 (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 
 (e) If the applicable Borrower fails to deliver a timely Interest Election Request with respect to a LIBOR Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such 

  

 21 








 
Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to (i) if such Loan is to a Borrower other
than a Canadian Borrower, a U.S. Base Rate Borrowing, or (ii) if such Loan is to a Canadian Borrower, a Canadian Base Rate Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the
Administrative Agent, at the request of the Required Lenders, so notifies Alcoa, then, so long as such Event of Default is continuing (A) no outstanding Borrowing may be converted to or continued as a LIBOR Borrowing and (B) unless repaid,
each LIBOR Borrowing shall be converted to, (x) if such Loan is to a Borrower other than a Canadian Borrower, a U.S. Base Rate Borrowing, and (y) if such Loan is to a Canadian Borrower, a Canadian Base Rate Borrowing, at the end of the
Interest Period applicable thereto. 
 SECTION 2.05. Evidence of Debt; Repayment of Loans. (a) The outstanding principal balance
of each Loan shall be payable on the Maturity Date. 
 (b) Each Lender shall maintain in accordance with its usual practice an account or
accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid such Lender from time to time under this Agreement.

 (c) The Administrative Agent shall maintain accounts in which it will record (i) the amount of each Loan made to a Borrower
hereunder, (ii) the Type of each such Loan and the Interest Period applicable thereto, (iii) the amount of any principal or interest due and payable or to become due and payable from the applicable Borrower to each Lender hereunder and
(iv) the amount of any sum received by the Administrative Agent hereunder from any Borrower and each Lender’s share thereof. 
 (d)
The entries made in the accounts maintained pursuant to paragraphs (b) and (c) above shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of any Borrower to repay the Loans in accordance with their terms. 
 (e) Notwithstanding any other provision of this Agreement, in the event any Lender shall request a promissory note evidencing the Loans made by it
hereunder (each a “Note”) to any Borrower, such Borrower shall deliver such a note, satisfactory to the Administrative Agent, payable to such Lender or its order, and the interests represented by such note shall at all times
(including after any assignment of all or part of such interests pursuant to Section 10.04) be represented by one or more promissory notes payable to the payee named therein or its order. 
 SECTION 2.06. Fees. (a) Alcoa agrees to pay, or cause any other Borrower to pay, in immediately available funds for the account of each
Lender a commitment fee on the actual daily amount by which the Commitments of such Lender exceeds such Lender’s Ratable Portion of the aggregate outstanding principal amount of each of the U.S. Loans and the Canadian/U.S. Loans (the
“Unused Commitment Fee”) from the date that is 60 days after the Effective Date through the end of the Credit Period at the Applicable Unused Commitment Fee Rate, payable in arrears (x) on the last Business Day of each calendar
quarter, commencing on the first such Business Day following the date that is 60 days after the Effective Date and (y) on the date that is the end of the Credit Period. All Unused Commitment Fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days. The Unused Commitment Fee shall be paid on the dates due, in immediately available funds, to the Administrative Agent, for distribution, if and as appropriate, among the Lenders. Once paid, the Unused
Commitment Fee shall not be refundable except in the case of an error which results in the payment of Unused Commitment Fee in excess of that due and payable as of such date, in which case the Administrative Agent shall cause a refund in the amount
of such excess to be paid to Alcoa. 
  

 22 








 (b) Alcoa agrees to pay, or cause any other Borrower to pay, to the Administrative Agent and the
Arrangers, for their respective accounts, the fees payable in the amounts and at the times separately agreed upon among Alcoa, such Borrowers, the Administrative Agent and the Arrangers. 
 SECTION 2.07. Interest on Loans. (a) Subject to the provisions of Section 2.08, the unpaid principal amount of the Loans comprising each
Base Rate Borrowing shall bear interest for each day (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, when the Base Rate is determined by reference to clause (a) of the definition
of each of “Canadian Base Rate” and “U.S. Base Rate”, as applicable, and over a year of 360 days at all other times) at a rate per annum equal to the Base Rate for the Interest Period in effect for such Borrowing
plus the Applicable Margin. 
 (b) Subject to the provisions of Section 2.08, the unpaid principal amount of the Loans comprising each
LIBOR Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin.

 (c) Interest on each Loan shall be payable on the Interest Payment Dates applicable to such Loan except as otherwise provided in this
Agreement. Interest shall accrue from and including the first day of an Interest Period to but excluding the last day of such Interest Period. The applicable LIBO Rate or Base Rate for each Interest Period or day within an Interest Period, as the
case may be, shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. 
 (d) For
the purposes of this Agreement and specifically in respect of any interest or fees on any Loan made to a Canadian Borrower, whenever any interest or any fee is to be calculated on the basis of a period that is less than the actual number of days in
a calendar year (e.g., 360 days), each rate of interest or fee determined pursuant to such calculation is, for the purposes of the Interest Act (Canada), equivalent to such rate (including the rate on which the fee is based) multiplied by the
actual number of days in the calendar year in which such rate is to be ascertained and divided by the number of days used as the basis of such calculation. The parties hereto acknowledge and agree that all calculations of interest under this
Agreement in respect of any Loan to a Canadian Borrower are to be made on the basis of the nominal interest rate described herein 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 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. 
 SECTION 2.08. Default Interest. If any Borrower shall default in the payment of the
principal of or interest on any Loan or any other amount becoming due hereunder, by acceleration or otherwise, such Borrower shall on demand from time to time pay interest, to the extent permitted by law, on such defaulted amount up to (but not
including) the date of actual payment (after as well as before judgment) at a rate per annum equal to (a) in the case of overdue principal of any Loan, the rate otherwise applicable to such Loan as provided in Section 2.07 plus 2% per
annum, or (b) in the case of any other amount, the rate applicable to Base Rate Borrowings plus 2% per annum. 
  

 23 








 SECTION 2.09. Alternate Rate of Interest. In the event, and on each occasion, that on the day two
Business Days prior to the commencement of any Interest Period for a LIBOR Loan, the Administrative Agent shall have determined in good faith that dollar deposits in the principal amounts of the Loans comprising such Borrowing are not generally
available in the London interbank market or other market in which Lenders ordinarily raise dollars to fund Loans of the requested Type, or that the rates at which such dollar deposits are being offered will not adequately and fairly reflect the cost
to any Lender of making or maintaining its LIBOR Loan during such Interest Period, or that reasonable means do not exist for ascertaining the LIBO Rate, then the Administrative Agent shall, as soon as practicable thereafter, give written or telecopy
notice of such determination to Alcoa and the Lenders. In the event of any such determination, any request made by a Borrower after the date of such notice for a LIBOR Borrowing pursuant to Section 2.03 or 2.04 shall, until the Administrative
Agent shall have advised Alcoa and the Lenders that the circumstances giving rise to such notice no longer exist, be deemed to be a request for a Base Rate Borrowing. Each determination by the Administrative Agent hereunder shall be conclusive
absent manifest error. 
 SECTION 2.10. Termination and Reduction of Commitments. (a) The Commitments shall terminate on the
Maturity Date. 
 (b) Upon at least ten Business Days’ prior irrevocable, written or telecopy notice (which notice may be conditioned
upon the closing of any financing arrangement obtained to refinance or replace either of the Facilities) to the Administrative Agent, Alcoa may at any time during the Credit Period in whole permanently terminate, or from time to time in part
permanently reduce, (i) the U.S. Commitments; provided, however, that (x) each such partial reduction shall be in an integral multiple of $5,000,000 and in a minimum principal amount of $50,000,000 and (y) the U.S.
Commitments shall not be reduced to an amount that is less than the aggregate principal amount of the outstanding U.S. Loans (after giving effect to any simultaneous prepayment pursuant to Section 2.11) (each a “U.S. Commitment
Reduction”), or (ii) the Canadian/U.S. Commitments; provided, however, that (x) each such partial reduction shall be in an integral multiple of $5,000,000 and in a minimum principal amount of $50,000,000 and
(y) the Canadian/U.S. Commitments shall not be reduced to an amount that is less than the aggregate principal amount of the outstanding Canadian/U.S. Loans (after giving effect to any simultaneous prepayment pursuant to Section 2.11) (each
a “Canadian/U.S. Commitment Reduction”). 
 (c) Each reduction in Commitments hereunder shall be made ratably among the
applicable Lenders in accordance with each such Lender’s Ratable Portion of the applicable Commitments. Alcoa shall pay, or cause any other Borrower to pay, to the Administrative Agent for the account of the applicable Lenders, on the date of
each such termination or reduction pursuant to this Section 2.10, the Unused Commitment Fee on the amount of the unused Commitments so terminated or reduced accrued to the date of such termination or reduction. 
 SECTION 2.11. Optional Prepayments. (a) Each Borrower shall have the right at any time and from time to time to prepay any Borrowing, in
whole or in part, upon at least three Business Days’ prior written or telecopy notice (or telephone notice promptly confirmed by written or telecopy notice) to the Administrative Agent; provided, however, that each such partial
prepayment shall be in an amount which is an integral multiple of $5,000,000 and not less than $50,000,000. 
 (b) On the date of any
termination or reduction of any Commitment pursuant to Section 2.10, the Borrowers shall pay or prepay so much of the Loans, as shall be necessary in order that, after giving effect to such reduction or termination, the aggregate principal
amount of the outstanding Loans shall not exceed (i) in the case of a U.S. Commitment Reduction, the U.S. Commitments and (ii) in the case of a Canadian/U.S. Commitment Reduction, the Canadian/U.S. Commitments. 
  

 24 








 (c) Each notice of prepayment shall specify the prepayment date and the principal amount of each Loan (or
portion thereof) to be prepaid, shall be irrevocable (but may be conditioned upon the closing of any financing arrangement obtained to refinance or replace either of the Facilities) and shall commit the applicable Borrower to prepay the Loan to
which such notice relates by the amount stated therein on the date stated therein. All prepayments under this Section 2.11 shall be subject to Section 2.15 but otherwise without premium or penalty. On the date of any prepayment of a
Borrowing pursuant to this Section 2.11, the Commitments under the Facility under which such Borrowing was made shall be reduced by an amount equal to the principal amount of such prepayment. All prepayments under this Section 2.11 shall
be accompanied by accrued interest on the principal amount being prepaid to the date of payment. Amounts of Loans prepaid or repaid may not be reborrowed. 
 SECTION 2.12. Mandatory Prepayments. Upon receipt by Alcoa or any of its Subsidiaries of Net Cash Proceeds arising from an Asset Sale, Equity Issuance or Debt Issuance, the Borrowers shall within ten Business
Days of the receipt thereof prepay the Loans in an amount equal to 100% of such Net Cash Proceeds; provided, however, that, notwithstanding the foregoing, (a) if such Net Cash Proceeds are received in connection with any Asset
Sale by Alcan or any of its Subsidiaries at any time prior to the Merger Consummation Date, the Borrowers may delay such mandatory prepayment until a date that is ten Business Days after the Merger Consummation Date, and (b) if a mandatory
prepayment of LIBOR Rate Loans is required pursuant to this Section 2.12 on a date that is not an Interest Payment Date, unless an Event of Default shall have occurred and be continuing, the Borrowers may delay such mandatory prepayment until
the earlier of (i) the next succeeding Interest Payment Date and (ii) a date that is 30 days after the receipt of the applicable Net Cash Proceeds. In the event the amount of Net Cash Proceeds to be applied to a mandatory prepayment
pursuant to this Section 2.12 exceeds the aggregate amount of the outstanding Obligations on the date such prepayment is made, the then current unused Commitments shall be reduced on such date in the amount of such excess (and the Commitments
of each Lender shall be reduced by its Ratable Portion of such amount). All prepayments under this Section 2.12 shall be subject to Section 2.15, if applicable, but otherwise without premium or penalty. All prepayments under this
Section 2.12 shall be accompanied by (i) accrued interest on the principal amount being prepaid to the date of payment and (ii) if, in connection with such prepayment the unused Commitments are to be reduced, the Unused Commitment Fee
on the amount of the unused Commitments so reduced accrued to the date of such prepayment. 
 SECTION 2.13. Reserve Requirements; Change
in Circumstances. (a) Notwithstanding any other provision herein other than Section 2.15(c) and with respect to Taxes (which shall be governed solely and exclusively by Section 2.19), if after the date of this Agreement any change
in applicable law or regulation or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law) shall impose, modify or deem
applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender that makes a LIBOR Loan or shall impose on such Lender or the London interbank market or other
market in which Lenders ordinarily raise dollars to fund Loans of the requested Type any other condition affecting this Agreement or LIBOR Loans made by such Lender, and the result of any of the foregoing shall be to increase the cost to such Lender
of funding, making or maintaining any LIBOR Loan or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), by an amount reasonably determined by such Lender to be material, then
Alcoa will pay or cause the other Borrowers to pay to such Lender upon demand such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 
  

 25 








 (b) If any Lender shall have determined that the applicability of any law, rule, regulation, agreement or
guideline adopted after the date of this Agreement pursuant to the July 1988 report of the Basle Committee on Banking Regulations and Supervisory Practices entitled “International Convergence of Capital Measurement and Capital
Standards”, or the adoption after the date hereof of any other law, rule, regulation, agreement or guideline regarding capital adequacy, or any change in any of the foregoing or in the interpretation or administration of any of the
foregoing by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or any lending office of such Lender) or any Lender’s holding company with any
request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s capital or on the
capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender pursuant hereto to a level below that which such Lender or such Lender’s holding company could have achieved but for such
applicability, adoption, change or compliance (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy) by an amount deemed by such Lender to be material, then
from time to time Alcoa shall pay or cause the other Borrowers to pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered. 
 (c) A certificate of each Lender setting forth such amount or amounts as shall be necessary to compensate such Lender or its holding company as specified
in paragraph (a) or (b) above, as the case may be, together with a statement of reasons for such demand and showing the calculation for such amounts shall be delivered to Alcoa and shall be conclusive absent manifest error. Alcoa shall pay
or cause to be paid to each Lender the amount shown as due on any such certificate delivered by it within ten days after its receipt of the same. 
 (d) Except as provided in this paragraph, failure on the part of any Lender to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to any period shall not
constitute a waiver of such Lender’s right to demand compensation with respect to such period or any other period. The protection of this Section 2.13 shall be available to each Lender regardless of any possible contention of the
invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition which shall have occurred or been imposed. No Lender shall be entitled to compensation under this Section 2.13 for any costs incurred or
reductions suffered with respect to any date unless it shall have notified Alcoa that it will demand compensation for such costs or reductions under paragraph (c) above not more than 60 days after the later of (i) such date and
(ii) the date on which it shall have or reasonably should have become aware of such costs or reductions. In the event a Borrower shall reimburse any Lender pursuant to this Section 2.13 for any cost and the Lender shall subsequently
receive a refund in respect thereof, the Lender shall so notify such Borrower and shall pay to such Borrower the portion of such refund which it shall determine in good faith to be allocable to the cost so reimbursed. 
 SECTION 2.14. Change in Legality. (a) Notwithstanding any other provision herein other than Section 2.15(c), if any change in any law or
regulation or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any LIBOR Loan or to give effect to its obligations as
contemplated hereby with respect to any LIBOR Loan, then, by written or telecopy notice to Alcoa and the Administrative Agent, such Lender may: 
 (i) declare that LIBOR Loans will not thereafter be made by such Lender hereunder, whereupon any request by a Borrower for a LIBOR Borrowing shall, as to such Lender only, be deemed a request for a Base Rate Loan
unless such declaration shall be subsequently withdrawn; and 
  

 26 








 (ii) require that all outstanding LIBOR Loans made by it be converted to Base Rate Loans,
in which event all such LIBOR Loans shall automatically be so converted as of the effective date of such notice as provided in paragraph (b) below. 
 In the event any Lender shall exercise its rights under clause (i) or (ii) above, all payments and prepayments of principal which would otherwise have been applied to repay the LIBOR Loans that would have been made by such Lender
or the converted LIBOR Loans of such Lender shall instead be applied to repay the Loans made by such Lender in lieu of, or resulting from the conversion of, such LIBOR Loans. 
 (b) For purposes of this Section 2.14, a notice by any Lender shall be effective as to each LIBOR Loan, if lawful, on the last day of the Interest
Period applicable to such LIBOR Loan; in all other cases such notice shall be effective on the date of receipt. 
 SECTION 2.15.
Indemnity. Alcoa shall indemnify or cause the other Borrowers to indemnify each Lender against any loss or expense (excluding loss of anticipated profits) which such Lender may sustain or incur as a consequence of (a) any failure to
fulfill on the date of any Borrowing hereunder the applicable conditions set forth in Article IV, (b) any failure by a Borrower to borrow any LIBOR Loan hereunder after irrevocable notice of such Borrowing has been given pursuant to
Section 2.03, (c) any payment or prepayment of a LIBOR Loan required by any other provision of this Agreement or otherwise made or deemed made on a date other than the last day of the Interest Period applicable thereto, other than any loss
of profit resulting from any event, circumstance or condition set forth in Section 2.13 or 2.14, (d) any default in payment or prepayment of the principal amount of any LIBOR Loan or any part thereof or interest accrued thereon, as and
when due and payable (at the due date thereof, whether by scheduled maturity, acceleration, irrevocable notice of prepayment or otherwise) or (e) the occurrence of any Event of Default, including, in each such case, any loss or reasonable
expense sustained or incurred or to be sustained or incurred in liquidating or employing deposits from third parties acquired to effect or maintain such Loan or any part thereof as a LIBOR Loan. Such loss or reasonable expense shall include an
amount equal to the excess, if any, as reasonably determined by such Lender, of (i) its cost of obtaining the funds for the Loan being paid, prepaid or not borrowed (assumed to be the LIBO Rate applicable thereto) for the period from the date
of such payment, prepayment or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow the Interest Period for such Loan which would have commenced on the date of such failure) over
(ii) the amount of interest (as reasonably determined by such Lender) that would be realized by such Lender in reemploying the funds so paid, prepaid or not borrowed for such period or Interest Period, as the case may be. A certificate of any
Lender setting forth any amount or amounts which such Lender is entitled to receive pursuant to this Section together with a statement of reasons for such demand and the calculation of such amount or amounts shall be delivered to Alcoa and shall be
conclusive absent manifest error. 
 SECTION 2.16. Pro Rata Treatment. Each (i) scheduled payment or prepayment pursuant to
Section 2.11, in each case of principal of any Borrowing under either Facility and (ii) reduction of Commitments under either Facility pursuant to Section 2.11, in each case of (i) and (ii) above, shall be applied to the
repayment of such Borrowing or reduction of such Commitments, as applicable, ratably among the Lenders under such Facility. Except as required under Section 2.14, each Borrowing under either Facility shall be allocated ratably among the Lenders
under such Facility in accordance with their respective Commitments under such Facility. Except as required under Section 2.14, each prepayment of principal of any Borrowing or reduction of Commitments pursuant to Section 2.12, each
payment of interest on the Loans, each payment of the Unused Commitment Fee on the unused 

  

 27 








 
Commitments and each conversion or continuation of any Borrowing with a Borrowing of any Type, shall be allocated pro rata among the Lenders in accordance
with their respective Commitments (or, if such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans). Each Lender agrees that in computing such Lender’s portion of any
Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing, computed in accordance with Schedule 2.01, to the next higher or lower whole dollar amount. 
 SECTION 2.17. Sharing of Setoffs. Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or
counterclaim against any Borrower, or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any
applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any Loan or Loans as a result of which the unpaid principal portion of its Loans shall be
proportionately less than the unpaid principal portion of the Loans of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a
participation in the Loans of such other Lender, so that the aggregate unpaid principal amount of the Loans and participations in Loans held by each Lender shall be in the same proportion to the aggregate unpaid principal amount of all Loans then
outstanding as the principal amount of its Loans prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the principal amount of all Loans outstanding prior to such exercise of banker’s lien, setoff or
counterclaim or other event; provided, however, that, if any such purchase or purchases or adjustments shall be made pursuant to this Section and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases
or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. Alcoa and each other Borrower expressly consent to the foregoing arrangements and agree that any Lender
holding a participation in a Loan deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by Alcoa or such other Borrower to such Lender by reason
thereof as fully as if such Lender had made a Loan directly to Alcoa or such Borrower in the amount of such participation. 
 SECTION 2.18.
Payments. (a) Each payment or prepayment by any Borrower of the principal of or interest on any Loans, any fees payable to the Administrative Agent or the Lenders or any other amounts due hereunder (other than amounts referred to in
clause (b) below) shall be made, without setoff or counterclaim, not later than 12:00 (noon), New York City time, on the date when due in dollars to the Administrative Agent at its offices at 2 Penns Way, Suite 110, New Castle, Delaware, in
immediately available funds. 
 (b) Whenever any payment (including principal of or interest on any Borrowing or any fees or other amounts)
hereunder shall become due, or otherwise would occur, on a day that is not a Business Day, except as provided in the definition of Interest Period, such payment may be made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of interest or fees, if applicable. 
 SECTION 2.19. Taxes. (a) Any and all payments by
or on behalf of a Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes. If any Borrower shall be required by law to deduct any Indemnified Taxes or Other Taxes from or in respect of any sum payable
hereunder to the Lenders (or any Transferee) or the Administrative Agent, (i) the sum payable shall be increased by the amount necessary so that after making all required deductions (including deductions applicable to additional sums payable
under this Section 2.19) such Lender (or 

  

 28 








 
Transferee) or the Administrative Agent (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been
made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law; provided,
however, that no Transferee of any Lender shall be entitled to receive any greater payment under this Section 2.19 than such Lender would have been entitled to receive immediately before assignment, participation or other transfer with
respect to the rights assigned, participated or transferred unless such assignment, participation or transfer shall have been made (A) prior to the occurrence of an event (including any change in treaty, law or regulation) giving rise to such
greater payment or (B) at the request of Alcoa. 
 (b) In addition, each Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement (herein referred to as
“Other Taxes”). 
 (c) Each Borrower will indemnify each Lender (or Transferee) and the Administrative Agent for the full
amount of Indemnified Taxes and Other Taxes (including any Indemnified Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.19(c)) paid by such Lender (or Transferee) or the Administrative Agent, as the case
may be, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Such indemnification shall be made within 30 days after the date any Lender (or Transferee) or the Administrative Agent, as the case
may be, makes written demand therefor, together with a statement of reasons for such demand and the calculations of such amount. Such calculations, if made in good faith, absent manifest error, shall be final and conclusive on all parties.

 (d) Within 30 days after the date of any payment of Indemnified Taxes or Other Taxes withheld by any Borrower in respect of any payment to
any Lender (or Transferee) or the Administrative Agent, such Borrower will furnish to the Administrative Agent, at its address referred to in Section 10.01, the original or a certified copy of a receipt evidencing payment thereof (or other
evidence satisfactory to the Administrative Agent). 
 (e) Without prejudice to the survival of any other agreement contained herein, the
agreements and obligations contained in this Section 2.19 shall survive the payment in full of the principal of and interest on all Loans made hereunder. 
 (f) Each Lender (or Transferee) represents to Alcoa that, on the date such Lender (or such Transferee) becomes a party to this Agreement, it is eligible to receive payments of interest hereunder from the Borrowers
without withholding in respect of United States Federal withholding tax (except, in the case of a Transferee of any Lender, as a result of the occurrence of an event (including a change in treaty, law or regulation) after the date of this Agreement
giving rise to withholding to which such Lender would be subject). 
 (g) Each Lender (or Transferee), other than a Transferee described in
the exception in Section 2.19(f)) that is not a “United States person,” within the meaning of Section 7701(a)(30) of the Code, shall, on or before the date it becomes a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on or before the date such Transferee becomes a participation holder hereunder), deliver to Alcoa and the Administrative Agent such certificates, documents or other evidence, as required by the Code or
Treasury Regulations issued pursuant thereto, including Internal Revenue Service Form W-8BEN, Form W-8ECI, or any other applicable certificate or statement of exemption, properly completed and duly executed by such Lender (or Transferee)
establishing that payment made to such 

  

 29 








 
Lender (or Transferee) is (i) not subject to United States Federal withholding tax under the Code because such payments are effectively connected with
the conduct by such Lender (or Transferee) of a trade or business in the United States, (ii) totally exempt from United States Federal withholding tax under a provision of an applicable tax treaty, or (iii) eligible for the benefits of the
exemption for portfolio interest under Section 881(c) of the Code, in which case such Lender shall also deliver a certificate to the effect that such Lender is not (A) a “bank” within the meaning of
Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of any of the Borrowers within the meaning of Section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation”
described in Section 881(c)(3)(C) of the Code. In addition, each such Lender (or such Transferee) shall, if legally able to do so, thereafter deliver such certificates, documents or other evidence from time to time establishing that payments
received hereunder are not subject to, or subject to a reduced rate of, such withholding upon receipt of a written request therefor from Alcoa or the Administrative Agent. Unless Alcoa and the Administrative Agent have received forms or other
documents satisfactory to them indicating that payments hereunder are not subject to, or subject to a reduced rate of, United States Federal withholding tax, Alcoa or the Administrative Agent shall withhold such taxes from such payments at the
applicable statutory rate. 
 (h) Each Lender (or Transferee) that is a “United States person,” within the meaning of
Section 7701(a)(30) of the Code, shall, on or before the date it becomes a party to this Agreement (or, in the case of a Transferee that is a participation holder, on or before the date such Transferee becomes a participation holder hereunder),
deliver to Alcoa and the Administrative Agent such certificates, documents or other evidence, as required by the Code or Treasury Regulations issued pursuant thereto, including Internal Revenue Service Form W-9 or any other applicable certificate or
statement of exemption properly completed and duly executed by such Lender (or Transferee) establishing that payment made to such Lender (or Transferee) is not subject to United States Federal backup withholding tax under the Code. In addition, each
such Lender (or such Transferee) shall, if legally able to do so, thereafter deliver such certificates, documents or other evidence from time to time establishing that payments received hereunder are not subject to such withholding upon receipt of a
written request therefor from Alcoa or the Administrative Agent. Unless Alcoa and the Administrative Agent have received forms or other documents satisfactory to them indicating that payments hereunder are not subject to United States Federal backup
withholding tax, Alcoa or the Administrative Agent shall withhold such taxes from such payments at the applicable statutory rate. 
 (i) Each
Lender (or Transferee) that is entitled to any exemption or reduction of non-U.S. withholding tax with respect to any payment under this Agreement shall, on or before the date it becomes a party to this Agreement (or, in the case of a Transferee
that is a participation holder, on or before the date such Transferee becomes a participation holder hereunder), deliver to Alcoa and the Administrative Agent such certificates, documents or other evidence, as required by law, or as may reasonably
be requested by Alcoa, establishing that such payment is not subject to, or is subject to a reduced rate of, withholding. In addition, each such Lender (or such Transferee) shall, if legally able to do so, thereafter deliver such certificates,
documents or other evidence from time to time establishing that payments received hereunder are not subject to such withholding upon receipt of a written request therefor from Alcoa or the Administrative Agent. 
 (j) None of the Borrowers shall be required to pay any additional amounts to any Lender (or Transferee) in respect of any withholding tax pursuant to
paragraph (a) above to the extent that the obligation to pay such additional amounts would not have arisen but for a failure by such Lender (or Transferee) to deliver the certificates, documents or other evidence required to be delivered under
the preceding paragraph (g), (h) or (i) unless such failure is attributable to (i) a change in applicable law, regulation or official interpretation thereof or (ii) an amendment or modification to or a revocation of any
applicable tax treaty or a change in official position regarding the application or interpretation thereof, in each case on or after the date such Lender (or Transferee) became a party to this Agreement. 
  

 30 








 (k) Any Lender (or Transferee) claiming any additional amounts payable pursuant to this Section 2.19
shall use reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to, at the expense of the Borrowers, file any certificate or document reasonably requested in writing by the relevant Borrower or to change
the jurisdiction of its applicable lending office if the making of such a filing or change would avoid the need for or reduce the amount of any such additional amounts which may thereafter accrue and would not, in the sole determination of such
Lender (or Transferee), be otherwise disadvantageous to such Lender (or Transferee). 
 (l) If any Lender (or Transferee) or the
Administrative Agent receives a refund in respect of any Indemnified Taxes or Other Taxes as to which it has been indemnified by a Borrower pursuant to this Section 2.19, it shall promptly repay such refund to such Borrower (to the extent of
amounts that have been paid by such Borrower under this Section 2.19 with respect to such refund), net of all out-of-pocket expenses (including Taxes imposed with respect to such refund) of such Lender (or Transferee) or the Administrative
Agent and without interest (other than interest paid by the relevant taxing authority with respect to such refund); provided, however, that such Borrower, upon the request of such Lender (or Transferee) or the Administrative Agent, agrees to return
such refund (plus penalties, interest or other charges) to such Lender (or Transferee) or the Administrative Agent in the event such Lender (or Transferee) or the Administrative Agent is required to repay such refund. Nothing in this
Section 2.19 shall obligate any Lender (or Transferee) or the Administrative Agent to apply for any such refund. 
 (m) Nothing
contained in this Section 2.19 shall require any Lender (or Transferee) or the Administrative Agent to make available any of its tax returns (or any other information relating to its Taxes which it deems to be confidential). 
 (n) No Borrower shall be required to reimburse any Lender (or Transferee) or the Administrative Agent with respect to any Indemnified Taxes or Other
Taxes unless such Lender, Transferee or the Administrative Agent notifies such Borrower of the amount of such Indemnified Taxes or Other Taxes on or before the second anniversary of the date such Lender, Transferee or the Administrative Agent pays
such Indemnified Taxes or Other Taxes. 
 SECTION 2.20. Assignment of Loans and Commitments Under Certain Circumstances. In the event
that any Lender shall have delivered a notice or certificate pursuant to Section 2.13 or 2.14, or a Borrower shall be required to make additional payments to any Lender under Section 2.19, Alcoa shall have the right, at its own expense,
upon notice to such Lender and the Administrative Agent, to require such Lender to transfer and assign without recourse (in accordance with and subject to the restrictions contained in Section 10.04) all its interests, rights and obligations
under this Agreement to another financial institution or other entity which shall assume such obligations; provided, however, that (i) no such assignment shall conflict with any law, rule or regulation or order of any Governmental
Authority and (ii) Alcoa or the assignee, as the case may be, shall pay (or, in the case of Alcoa, cause another Borrower to pay) to the affected Lender in immediately available funds on the date of such termination or assignment the principal
of and interest accrued to the date of payment on the Loans made by it hereunder and all other amounts accrued for its account or owed to it hereunder. 
  

 31 








 ARTICLE III 
 REPRESENTATIONS AND WARRANTIES 
 Alcoa represents and warrants to each of the Lenders as
follows (provided that no representations or warranties under Sections 3.08 through and including 3.14 shall be made with respect to Alcan or any of its Subsidiaries (or with respect to any entity into which Alcan is amalgamated, merged into
or otherwise consolidated with or any of such entity’s Subsidiaries) until the date that is 60 days after the Merger Consummation Date): 
 SECTION 3.01. Organization. Each Restricted Group Member (a) is duly organized, validly existing and, where applicable, in good standing under the laws of its jurisdiction of organization and (b) is duly qualified to do
business as a foreign corporation and where applicable, is in good standing; to the extent such concept is applicable, in all other jurisdictions in which the ownership of its properties or the nature of its activities or both makes such
qualification necessary, except to the extent that failure to be so qualified would not result in a Material Adverse Effect. 
 SECTION 3.02.
Authorization. Each Restricted Group Member has power and authority, corporate or otherwise, to (a) execute, deliver and carry out the provisions of this Agreement and each other Transaction Document to which it is a party,
(b) guarantee any Obligations to the extent required hereunder and/or borrow hereunder, as applicable, and (c) perform its obligations hereunder, under each other agreement that is a Transaction Document to which it is a party, and
otherwise in connection with the Transactions all such action has been duly and validly authorized by all necessary proceedings, corporate or otherwise, on its part. 
 SECTION 3.03. Enforceability. This Agreement and each other agreement that is a Transaction Document to which any Restricted Group Member is a party has been duly executed and delivered by such Restricted Group
Member and constitutes the legal, valid and binding obligation of such Restricted Group Member enforceable in accordance with its terms, except as limited by bankruptcy, insolvency or other similar laws of general application affecting the
enforcement of creditors’ rights or by general principles of equity limiting the availability of equitable remedies. 
 SECTION 3.04.
Governmental Approvals. No authorization, consent, approval, license, exemption or other action by, and no registration, qualification, designation, declaration or filing with, any Governmental Authority is necessary in connection with any
Restricted Group Member’s execution and delivery of this Agreement and each other Transaction Document to which such Restricted Group Member is a party, the consummation by any Restricted Group Member of the Transactions or any Restricted Group
Member’s performance of or compliance with the terms and conditions hereof or thereof, except for those that have been or will be obtained or performed and are or will be in full force and effect, in each case prior to the date any such
authorization, consent, approval, license, exemption or other action by, or registration, qualification, designation, declaration or filing with, any Governmental Authority, is required to be obtained, made or taken. 
 SECTION 3.05. No Conflict. None of the execution and delivery by any Restricted Group Member of this Agreement and each other Transaction Document
to which such Restricted Group Member is a party, the consummation by such Restricted Group Member of the Transactions or performance by such Restricted Group Member of or compliance by such Restricted Group Member with the terms and conditions
hereof or thereof will (a) violate any law, constitution, statute, treaty, regulation, rule, ordinance, order, injunction, writ, decree or award of any Governmental Authority to which such Restricted Group Member is subject, (b) conflict
with or result in a breach or default under such 

  

 32 








 
Restricted Group Member’s charter or Memorandum and Articles of Association or by-laws (or equivalent organizational or governing documents), as
applicable, (c) conflict with or result in a breach or default which is material in the context of this Agreement under any agreement or instrument to which such Restricted Group Member is a party or by which it or any of its properties,
whether now owned or hereafter acquired, may be subject or bound or (d) result in the creation or imposition of any Lien prohibited by Section 6.01 upon any property or assets, whether now owned or hereafter acquired, of such Restricted
Group Member. 
 SECTION 3.06. Financial Statements. Alcoa has furnished to the Lenders copies of its consolidated balance sheet as of
December 31, 2005 and 2006, and the related consolidated statements of income and shareholders’ equity and cash flows for the three years ended December 31, 2006, all audited by PricewaterhouseCoopers LLP, and Alcoa’s unaudited
consolidated balance sheets as at March 31, 2007 and the related unaudited consolidated statements of income and shareholders’ equity and cash flows for the three months then ended. Such financial statements (including the notes thereto)
present fairly the financial condition of Alcoa and its Subsidiaries as of such dates and the results of their operations and cash flows for the periods then ended (subject, in the case of said balance sheets as at March 31, 2007, and said
statements of income, shareholders equity and cash flows for the three months then ended, to the absence of footnote disclosure and normal year-end audit adjustments), all in conformity with GAAP. 
 SECTION 3.07. No Defaults. No event has occurred and is continuing and no condition exists which constitutes a Default or Event of Default
hereunder. No Restricted Group Member is in violation of (a) any term of its charter, certificate of incorporation, or constitution or by-laws (or the equivalent organizational or governing documents), as applicable, or (b) any agreement
or instrument to which it is a party or by which it or any of its properties may be subject or bound where such violation is likely to result in a Material Adverse Effect. 
 SECTION 3.08. Litigation. Except as set forth in the financial statements referred to in Section 3.06 or the Exchange Act Reports or
otherwise disclosed on Schedule 3.08, there is no pending or, to the knowledge of any of its Responsible Officers, threatened proceeding by or before any Governmental Authority against Alcoa or any of its Subsidiaries, other than such proceeding
brought by any shareholder or noteholder of Alcan or Alcoa resulting directly from the Transactions, which in the opinion of Alcoa’s counsel is likely to result in a Material Adverse Effect. 
 SECTION 3.09. Employee Benefit Plans. (a) U.S. Plans. Each Plan is in compliance with all requirements of ERISA and the regulations
and published interpretations thereunder except to the extent such non-compliance could not reasonably be expected to result in a Material Adverse Effect. No Reportable Event has occurred as to which any Restricted Group Member or any ERISA
Affiliate was required to file a report with the PBGC that alone or together with any other Reportable Event would reasonably be expected to result in a liability of such Restricted Group Member to the PBGC in an aggregate amount in excess of
$50,000,000. The aggregate present value of all benefit liabilities under the Plans (based on the assumptions used to fund such Plans) did not, as of the last annual valuation dates applicable thereto, exceed the aggregate value of the assets of the
Plans by more than 10% of Consolidated Net Worth. Neither such Restricted Group Member nor any ERISA Affiliate has incurred any Withdrawal Liability that would reasonably be expected to result in a Material Adverse Effect. Neither such Restricted
Group Member nor any ERISA Affiliate has received any notification that any Multiemployer Plan is in reorganization or has been terminated within the meaning of Title IV of ERISA, and no Responsible Officer of any Restricted Group Member has
knowledge of any fact which would reasonably be expected to result in the reorganization or termination of a Multiemployer Plan where such reorganization or termination has resulted or would reasonably be expected to result, through increases in the
contributions required to be made to such Plan or otherwise, in a Material Adverse Effect.

 (b) Foreign Plans. Each Foreign Plan is in compliance with all requirements of law applicable
thereto and the respective requirements of the governing documents for such plan except to the extent such non-compliance could not reasonably be expected to result in a Material Adverse Effect. With respect to each Foreign Pension Plan, none of the
Restricted Group Members, their respective Affiliates or any of their directors, officers, employees or agents has engaged in a transaction which would subject any of the Restricted Group Members, directly or indirectly, to a tax or civil penalty
which could reasonably be expected to result in a Material Adverse Effect. With respect to each Foreign Plan, adequate reserves have been established in the financial statements furnished to Lenders in respect of any unfunded liabilities in
accordance with applicable law and prudent business practice or, where required, in accordance with ordinary accounting practices in the jurisdiction in which such Foreign Plan is maintained. The aggregate unfunded liabilities, after giving effect
to any such reserves for such liabilities, with respect to such Foreign Plans could not reasonably be expected to result in a Material Adverse Effect. There are no actions, suits or claims (other than routine claims for benefits) pending or
threatened in writing against any of the Restricted Group Members or any of their Affiliates with respect to any Foreign Plan which could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. 

SECTION 3.10. Title to Properties; Possession Under Leases. (a) Each Restricted Group Member and each of its Subsidiaries have good and
marketable title to, or valid leasehold interests in, all its material properties and assets, except for minor defects in title that do not materially interfere with its ability to conduct its business as currently conducted or to utilize such
properties and assets for their intended purposes. 
 (b) Each Restricted Group Member and each of its Subsidiaries have complied with all
material obligations under all material leases to which it is a party and all such leases are in full force and effect. Each Restricted Group Member and its Subsidiaries enjoy peaceful and undisturbed possession under all such material leases.

 SECTION 3.11. Investment Company Act; Public Utility Holding Company Act. No Restricted Group Member is an “investment
company” as defined in, or subject to regulation under, the Investment Company Act of 1940. Alcoa is exempted as, and no Restricted Group Member (other than Alcoa) is, a “holding company” as defined in, or subject to
regulations under, the Public Utility Holding Company Act of 1935, as amended, or, as the case may be, the Public Utility Holding Company Act of 2005, enacted as part of the Energy Policy Act of 2005, Pub. L. No. 109-58 as codified at
§§ 1261 et seq., and the regulations adopted thereunder, as amended. 
 SECTION 3.12. Tax Returns. Each Borrower and its
Subsidiaries have filed or caused to be filed all material Federal, state, local and foreign tax returns required to have been filed by it in all jurisdictions in which such tax returns are required to be filed and all such tax returns are true,
complete and correct in all material respects. Each Borrower and its Subsidiaries has paid or caused to be paid all material taxes shown to be due and payable on such returns or on any assessments received by it, except taxes that are being
contested in good faith by appropriate proceedings and for which adequate reserves are maintained on the applicable financial statements in accordance with GAAP. 
 SECTION 3.13. Compliance with Laws and Agreements. (a) None of the Restricted Group Members nor any of their Subsidiaries is in violation of any law, rule or regulation, or in default with respect to any
judgment, writ, injunction or decree of any Governmental Authority, where such violation or default would reasonably be expected to result in a Material Adverse Effect. 
  

 34 








 (b) None of the Restricted Group Members nor any of their Subsidiaries is in default in any material
manner under any provision of any indenture or other agreement or instrument evidencing Indebtedness, or any other material agreement or instrument to which it is a party or by which it or any of its properties or assets are or may be bound, where
such default would be reasonably likely to result in a Material Adverse Effect. 
 SECTION 3.14. No Material Misstatements. Except for
information not prepared by or on behalf of a Restricted Group Member and expressly disclaimed thereby, no information, report, financial statement, exhibit or schedule, when taken as a whole, furnished by or on behalf of any Restricted Group Member
to the Administrative Agent, the Arrangers or any Lender in connection with this Agreement, the Tender Offer Documents or the consummation of the Transactions or included herein or delivered pursuant thereto, including the information contained in
the Tender Offer Documents, contained or contains (and, with respect to any information relating to Alcan and it Subsidiaries prepared by or supplied by Alcoa or any other Restricted Group Member prior to the Tender Funding Date, to the knowledge of
Alcoa contained or contains), and as modified or supplemented by other information so furnished, any material misstatement of fact or omitted or omits to state any material fact (known to Alcoa in the case of any information or document not
furnished by it or any other Restricted Group Member) necessary to make the statements therein, when taken as a whole, in the light of the circumstances under which they were or are made, not misleading; provided, however, that no
representation is made as to projections or pro forma financial information except as set forth in the next sentence. Any projections and pro forma financial information contained in such materials are based upon good faith estimates and assumptions
believed by Alcoa to be reasonable at the time made, it being recognized by the Administrative Agent and the Lenders that such projections as to future events are not to be viewed as facts and that actual results during the period or periods covered
by any such projections may differ from the projected results. 
 SECTION 3.15. Use of Proceeds. The proceeds of any Loan will be used
to (a) finance a portion of the cash component of the Capital Contribution, (b) purchase the Shares, (c) at Alcoa’s election, refinance some or all of the outstanding obligations under the Designated Existing Indebtedness,
(d) finance the consummation of the other Transactions and (e) pay related transaction costs, fees and expenses. For avoidance of doubt, any Borrower may on-lend proceeds of any Loan to Alcoa or any of its Subsidiaries; provided,
however, that the proceeds of such intercompany loans shall be used by Alcoa or such Subsidiary for the purposes specified in this Section 3.15. 
 SECTION 3.16. No Trusts. No Restricted Group Member is entering into this Agreement in its capacity as trustee of any trust. 
 SECTION 3.17. Solvency. Both before and after giving effect to (a) the Loans to be made or extended on the Tender Funding Date or such other date as Loans requested hereunder are made or extended,
(b) the disbursement of the proceeds of such Loans pursuant to the instructions of the Borrowers, (c) the Tender Offer, the Merger and the consummation of the other financing transactions contemplated hereby and by the other Transaction
Documents and (d) the payment and accrual of all transaction costs in connection with the foregoing, Alcoa and its consolidated Subsidiaries, taken as a whole, are Solvent. 
 SECTION 3.18. Federal Reserve Regulations; Margin Stock. No part of the proceeds of any Loan to any Borrower will be used, whether directly or
indirectly, and whether immediately, 

  

 35 








 
incidentally or ultimately, for any purpose that entails a violation of any of the Regulations of the Board, including Regulations U and X. The outstanding
stock of each of Alcoa’s Subsidiaries is duly authorized, validly issued, fully paid and nonassessable and, other than the Shares (prior to the Merger Consummation Date) is not Margin Stock.

 ARTICLE VIII 
 GUARANTEE 
 In order to induce the Administrative Agent and the Lenders to execute and deliver
this Agreement and to make and maintain the Loans: 
 (a) Alcoa unconditionally and irrevocably guarantees, as a principal obligor and not
merely as a surety, the due and punctual payment in full and performance of all Borrowing Subsidiaries Obligations. Alcoa further agrees that the Borrowing Subsidiaries Obligations may be extended or renewed, in whole or in part, without notice or
further assent from it, and that it will remain bound upon the provisions of this Article VIII notwithstanding any extension or renewal of any Borrowing Subsidiaries Obligation. 
 (b) Alcoa waives presentation to, demand of payment from and protest to any Borrowing Subsidiary of any of the Borrowing Subsidiaries Obligations, and
also waives notice of acceptance of the guarantee set forth in this Article VIII and notice of protest for nonpayment. The obligations of Alcoa hereunder shall not be affected by (i) the failure of the Administrative Agent or any Lender to
assert any claim or demand or to enforce any right or remedy against any Borrower under the provisions of this Agreement or any guarantee; (ii) any extension or renewal of any provision of this Agreement or any guarantee; or (iii) any
rescission, waiver, amendment or modification of any of the terms or provisions of this Agreement or any guarantee or any other agreement. 
 (c) Alcoa further agrees that the guarantee set forth in this Article VIII constitutes a guarantee of payment when due and not of collection and waives any right to require that any resort be had by the Administrative Agent or any Lender to
the balance of any deposit account or credit on the books of the Administrative Agent or the relevant Lender, as applicable, in favor of any Borrower or any other person. 
 (d) The obligations of Alcoa hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim or waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Borrowing Subsidiaries Obligations or otherwise. Without limiting the generality of
the foregoing, the obligations of Alcoa hereunder shall not be discharged or impaired or otherwise affected by the failure of the 

  

 49 








 
Administrative Agent or any Lender to assert any claim or demand or to enforce any remedy under this Agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of the Borrowing Subsidiaries Obligations or by any other act or omission which may or might in any manner or to any extent vary the risk of Alcoa or would otherwise operate
as a discharge of Alcoa as a matter of law or equity (other than the defense of payment in satisfaction of such Obligation). 
 (e) Alcoa
further agrees that this guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment by any Borrower to the Administrative Agent or any Lender, or any part thereof, of principal of or interest on such
Borrowing Subsidiaries Obligation is rescinded or must otherwise be restored by the Administrative Agent or any Lender or any holder of any Borrowing Subsidiaries Obligation upon the bankruptcy or reorganization of such Borrowing Subsidiary or
otherwise. 
 (f) In furtherance of the foregoing and not in limitation of any other right which the Administrative Agent or any Lender may
have at law or in equity against Alcoa by virtue hereof, upon the failure of any Borrowing Subsidiary to pay any Borrowing Subsidiaries Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of
prepayment or otherwise, Alcoa hereby promises to and will, upon receipt of written demand by the Administrative Agent, promptly pay, or cause to be paid, to such Agent in cash the amount of such unpaid Borrowing Subsidiaries Obligation, and
thereupon such Agent shall assign, in any reasonable manner, the amount of the Borrowing Subsidiaries Obligation paid by Alcoa pursuant to this guarantee to Alcoa, such assignment to be pro tanto to the extent to which the Borrowing
Subsidiaries Obligation in question was discharged by Alcoa, or make such other disposition thereof as Alcoa shall direct (all without recourse to the Administrative Agent or any Lender and without any representation or warranty by the
Administrative Agent or Lender). 
 (g) Upon payment by Alcoa of any sums to the Administrative Agent as provided above, all rights of Alcoa
against the other Borrowers arising as a result thereof by way of right of subrogation or otherwise shall in all respects be subordinate and junior in right of payment to the prior indefeasible payment in full of all the Borrowing Subsidiaries
Obligations.

Section 311(b)(3) of the Trust Indenture Act. 
 (e) Neither the Syndication Agent nor any Arranger shall have obligations or duties
whatsoever in such capacity under this Agreement or any other Loan Document and shall incur no liability hereunder or thereunder in such capacity. 
 SECTION 9.02. Administrative Agent’s Reliance, Etc. None of the Administrative Agent, any of its Affiliates or any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to
be taken by it, him, her or them under or in connection with this Agreement or the other Loan Documents, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted primarily from the gross negligence or willful misconduct of such person. Without limiting the foregoing, the Administrative Agent (a) may treat the payee of any Note as its holder until such Note has been assigned
in accordance with Section 10.04, (b) may rely on the Register to the extent set forth in Section 2.05 and Section 10.04(b), (c) may consult with legal counsel (including counsel to the Borrowers or any other Restricted

certificate or other instrument or writing (which writing may be a telecopy or electronic mail) or any telephone message believed by it to be genuine and signed or sent by the proper party or parties. 
  

 51 








 SECTION 9.03. Posting of Communications. (a) Alcoa and each other Borrower hereby agrees that
it will provide to the Administrative Agent all information, documents and other materials that it is obligated, or otherwise chooses to, furnish to the Administrative Agent pursuant to any Loan Document or in connection with the transactions
contemplated therein, including, without limitation, all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (i) relates to a request for

but shall not be obligated to, make the Communications available to the Lenders by posting the Communications on IntraLinksTM or a substantially similar electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”). 
 (c) Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies
implemented or modified by the Administrative Agent from time to time (including, as of the Effective Date, a dual firewall and a User ID/Password Authorization System) and the Approved Electronic Platform is secured through a single-user-per-deal
authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders and each Restricted Group Member acknowledges and agrees that the distribution of material through an electronic
medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. Each of the Lenders and each Restricted Group Member hereby approves distribution of the Communications through the Approved
Electronic Platform and understands and assumes the risks of such distribution. 
 (d) THE APPROVED ELECTRONIC PLATFORM AND THE
COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. THE APPLICABLE PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE APPROVED ELECTRONIC PLATFORM AND
EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC PLATFORM AND THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE APPLICABLE PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM. IN NO EVENT SHALL THE
ADMINISTRATIVE AGENT, ANY ARRANGER, THE SYNDICATION AGENT OR ANY OF THEIR RESPECTIVE AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, “APPLICABLE PARTIES”) HAVE ANY
LIABILITY TO ALCOA, ANY OTHER RESTRICTIVE GROUP MEMBER, ANY LENDER OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR

CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF ALCOA’S OR ANY OTHER BORROWER’S OR THE
ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET. 
 (e) The Administrative Agent agrees that the receipt of
the Communications by the Administrative Agent at its Email address set forth above shall constitute effective delivery of the Communications to the Administrative Agent for purposes of the Loan Documents. Each Lender agrees that notice to it (as
provided in the next sentence) specifying that the Communications have been posted to the Approved Electronic Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees
(i) to notify the Administrative Agent in writing (including by electronic communication) from time to time of such Lender’s Email address to which the foregoing notice may be sent by electronic transmission and (ii) that the
foregoing notice may be sent to such Email address. 
 (f) Each of the Lenders and each Restricted Group Member agrees that the
Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally applicable document
retention procedures and policies. 
 (g) Nothing herein shall prejudice the right of the Administrative Agent or any Lender to give any
notice or other communication pursuant to any Loan Document in any other manner specified in such Loan Document. 
 SECTION 9.04. The
Administrative Agent Individually. With respect to its Ratable Portion, CNAI shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any
other Lender. The terms “Lenders”, “Required Lenders” and any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity as a Lender or as one of
the Required Lenders. CNAI and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with, any Restricted Group Member as if CNAI were not acting as the Administrative Agent.

 SECTION 9.05. Indemnification. Each Lender agrees to indemnify the Administrative Agent and each of its Affiliates, and each of
their respective directors, officers, employees, agents and advisors (to the extent not reimbursed by the Borrowers, but without affecting the Borrowers’ reimbursement obligation), from and against such Lender’s aggregate ratable share of
any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements (including fees, expenses and disbursements of financial and legal advisors) of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against, the Administrative Agent or any of its Affiliates, directors, officers, employees, agents and advisors in any way relating to or arising out of this Agreement or the other Loan Documents or any action
taken or omitted by the Administrative Agent under this Agreement or the other Loan Documents; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements to the extent any of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements is found in a final, non-appealable judgment by a court of
competent jurisdiction to have resulted primarily from the gross negligence or willful misconduct of the Administrative Agent or such Affiliate. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon
demand for its ratable share of any out-of-pocket expenses (including fees, expenses and disbursements of financial and legal advisors) 

  

 53 








 
incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in respect of its rights or responsibilities under, this Agreement or the other Loan Documents, to the extent that the Administrative Agent is not reimbursed for such expenses
by the Borrowers or another Restricted Group Member. 
 SECTION 9.06. Successor Administrative Agent. The Administrative Agent may
resign at any time by giving 30 days prior written notice thereof to the Lenders and Alcoa, whether or not a Successor Administrative Agent has been appointed. Upon any such resignation, the Required Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of
resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, selected from among the Lenders. In either case, such appointment shall be subject to the prior written approval of Alcoa
(which approval may not be unreasonably withheld and shall not be required upon the occurrence and during the continuance of an Event of Default). Upon the acceptance of any appointment as Administrative Agent by a successor Administrative Agent,
such successor Administrative Agent shall succeed to, and become vested with, all the rights, powers, privileges and duties of the retiring Administrative Agent. Upon the earlier of (x) the date that is 30 days after the giving by the existing
Administrative Agent of a resignation notice pursuant to this Section 9.06 and (y) the acceptance of appointment as Administrative Agent by a successor Administrative Agent, the retiring Administrative Agent shall be discharged from its
duties and obligations under this Agreement and the other Loan Documents. Prior to any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the retiring Administrative Agent shall take such action as may be reasonably
necessary to assign to the successor Administrative Agent its rights as Administrative Agent under the Loan Documents. After such resignation, the retiring Administrative Agent shall continue to have the benefit of this Article IX as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

 SECTION 10.03. Binding Effect. This Agreement shall become effective when it shall have been executed by each of Alcoa, Alcoa Holdco Canada and

under or by reason of this Agreement. 
  

 55 








 (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or
more assignees (other than to any Borrower or any Borrower’s Subsidiary or Affiliate) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) to
(1) any other Lender or an Affiliate of such Lender or (2) with the prior written consent (such consent not to be unreasonably withheld) of: 
 (A) Alcoa; provided that no consent of Alcoa shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default under clause (a), (b),
(g) or (h) of Article VII has occurred and is continuing, any other assignee; and 
 (B) the Administrative Agent.

 (ii) Assignments shall be subject to the following conditions: 
 (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender’s Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative
Agent) shall not be less than $5,000,000 or an integral multiple thereof, unless each of Alcoa and the Administrative Agent otherwise consent; provided that no such consent of Alcoa shall be required if an Event of Default under clause (a),
(b), (g) or (h) of Article VII has occurred and is continuing); 
 (B) each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement; 
 (C) the
parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; 
 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and 

(E) in the case of an assignment to a CLO (as defined below), the assigning Lender shall retain the sole right to approve any
amendment, modification or waiver of any provision of this Agreement; provided that the Assignment and Assumption between such Lender and such CLO may provide that such Lender will not, without the consent of such CLO, agree to any amendment,
modification or waiver described in the proviso to Section 10.08(b) that affects such CLO. 
 For purposes of this
Section 10.04(b), the terms “Approved Fund” and “CLO” have the following meanings: 
 “Approved
Fund” shall mean (a) a CLO and (b) with respect to any Lender that is a fund which invests in bank loans and similar extensions of credit, any other fund that invests in bank loans and similar extensions of credit and is managed
by the same investment advisor as such Lender or by an Affiliate of such investment advisor. 
  

 56 








 “CLO” shall mean any entity (whether a corporation, partnership, trust or otherwise)
that is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its business and is administered or managed by a Lender or an Affiliate of such Lender. 
 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date
specified in each Assignment and Assumption the assignee thereunder shall be a party hereto with respect to the interests assumed and, to the extent of the interest assigned under such Assignment and Assumption, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption
covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.15, 2.19 and 10.05). 
 (iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices a copy of each
Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time
(the “Register”). The entries in the Register shall be conclusive in the absence of manifest error, and the Borrowers, the Administrative Agent and the Lenders shall treat each person whose name is recorded in the Register pursuant
to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon
reasonable prior notice. 
 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender
and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (ii) (C) of this Section 10.04(b) and
any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall promptly (i) accept such Assignment and Assumption, (ii) record the information contained therein in the Register and
(iii) give notice thereof to Alcoa. No assignment shall be effective for purposes of this Agreement until it has been recorded in the Register as provided in this paragraph. 
 (c) (i) Any Lender may, without the consent of any Borrower and the Administrative Agent, sell participations to one or more banks or other entities (a
“Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s
obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not,
without the consent of the Participant, agree to any amendment, modification or waiver described in the provisos to Section 10.08(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, Alcoa agrees that each Participant
shall be entitled to the benefits of Sections 2.13 and 2.19 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also
shall be entitled to the benefits of Section 10.06 as though it were a Lender, provided such Participant agrees to be subject to Section 2.17 as though it were a Lender. 
  

 57 








 (ii) A Participant shall not be entitled to receive any greater payment under
Section 2.13 or 2.19 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with Alcoa’s prior written
consent or unless the right to a greater payment results from a change in law after the Participant becomes a Participant with respect to such participation. 
 (d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank, and the other provisions of this Section 10.04 shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall
release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (e)
Unless an Event of Default has occurred and is continuing, Alcoa at any time and from time to time, upon not less than five Business Days’ notice to the Administrative Agent may designate (i) any Approved Borrowing Subsidiary and
(ii) any wholly-owned Subsidiary of Alcoa reasonably satisfactory to the Arrangers, in each case of (i) and (ii) above, to be a Borrowing Subsidiary upon the completion of the following: (A) each of Alcoa and such Subsidiary
shall have executed and delivered to the Administrative Agent a Designation of Borrowing Subsidiary and (B) such Subsidiary shall have complied with Section 4.04, whereupon (1) such Subsidiary shall become a party hereto and shall
have the rights and obligations of a Borrowing Subsidiary hereunder and (2) the obligations of such Subsidiary shall become part of the Obligations and the guarantee of Alcoa pursuant to Article VIII hereof shall apply thereto to the same
extent that it applies to the other Obligations (the date on which any such designation shall occur being called a “Designation Date”). Following the giving of notice pursuant to the first sentence of this paragraph, if the
designation of such Subsidiary obligates the Administrative Agent or any Lender to comply with “know your customer” or similar identification procedures in circumstances where the necessary information is not already available to
it, Alcoa and such Subsidiary shall, promptly upon the request of the Administrative Agent or any Lender, supply such documentation or other evidence as is reasonably requested by the Administrative Agent or any Lender in order for the
Administrative Agent or such Lender, as applicable, to comply with “know your customer” and other applicable laws and regulations. 
 (f) If Alcoa shall designate as a Borrowing Subsidiary hereunder any Subsidiary not organized under the laws of the United States or any State thereof, any Lender may, with notice to the Administrative Agent and Alcoa, fulfill its
Commitment by causing an Affiliate of such Lender to act as the Lender in respect of such Borrowing Subsidiary (and such Lender shall, to the extent of Loans made to such Subsidiary Borrower, be deemed for all purposes hereof to have pro
tanto assigned such Loans to such Affiliate in compliance with the provisions of this Section 10.04). Upon receiving such notice, the Administrative Agent shall record the relevant information in the Register pursuant to
Section 10.04(b)(v). 
 SECTION 10.05. Expenses; Indemnity. (a) The Borrowers agree upon demand to pay, or reimburse the
Administrative Agent, the Syndication Agent and each of the Arrangers for all of each such person’s reasonable and documented out-of-pocket costs and expenses of every type and nature (including the reasonable fees, expenses and disbursements
of the Administrative Agent’s counsel, Weil, Gotshal & Manges LLP) incurred by each such person in connection with any of the following: (i) the Administrative Agent’s negotiation or execution of any Loan Document,
(ii) the preparation, negotiation, 

  

 58 








 
execution or interpretation of this Agreement (including the satisfaction or attempted satisfaction of any condition set forth in Article IV), any Loan
Document or any proposal letter or commitment letter issued in connection therewith, or the making of the Loans hereunder, (iv) the ongoing administration of this Agreement and the Loans, including consultation with attorneys in connection
therewith and with respect to the Administrative Agent’s rights and responsibilities hereunder and under the other Loan Documents, (v) the protection, collection or enforcement of any Obligation or the enforcement of any Loan Document,
(vi) the commencement, defense or intervention in any court proceeding relating in any way to the Obligations, the Tender Offer, the other Transactions, the Related Documents, this Agreement or any other Loan Document, (vii) the response
to, and preparation for, any subpoena or request for document production with which the Administrative Agent is served or deposition or other proceeding in which the Administrative Agent is called to testify, in each case, relating in any way to the
Obligations, the Tender Offer, the other Transactions, the Related Documents, this Agreement or any other Loan Document or (viii) any amendment, consent, waiver, assignment, restatement, or supplement to any Loan Document or the preparation,
negotiation and execution of the same. 
 (b) The Borrowers further agree to pay or reimburse the Administrative Agent and each of the
Lenders upon demand for all out-of-pocket costs and expenses, including reasonable attorneys’ fees (which shall be limited to one primary counsel and one local counsel per each applicable jurisdiction), incurred by the Administrative Agent or
such Lenders in connection with any of the following: (i) in enforcing any Loan Document or Obligation or exercising or enforcing any other right or remedy available by reason of an Event of Default, (ii) in connection with any refinancing
or restructuring of the credit arrangements provided hereunder in the nature of a “work-out” or in any insolvency or bankruptcy proceeding, (iii) in commencing, defending or intervening in any litigation or in filing a
petition, complaint, answer, motion or other pleadings in any legal proceeding relating to the Obligations, any Restricted Group Member, any of the Borrowers’ respective Subsidiaries and related to or arising out of the transactions
contemplated hereby or by any other Loan Document or Related Document or (iv) in taking any other action in or with respect to any suit or proceeding (bankruptcy or otherwise) described in clause (i), (ii) or (iii) above. 

(c) The Borrowers agree to hold harmless the Administrative Agent, each Lender, the Syndication Agent, each Arranger and each of their respective
affiliates and each of their respective officers, directors, employees, agents, advisors, attorneys and representatives (each, an “Indemnitee”) from and against any and all claims, damages, losses, liabilities and expenses
(including, without limitation, fees and disbursements of counsel (which shall be limited to one primary counsel and one local counsel per each applicable jurisdiction for the Administrative Agent, the Syndication Agent, the Arrangers or any Lender,
unless, in the reasonable opinion of the Administrative Agent, representation of all such Indemnitees would be inappropriate due to an actual or potential conflict of interest, in which case there shall be permitted one additional counsel for such
affected Indemnitees), joint or several, that may be incurred by or asserted or awarded against any Indemnitee (including in connection with or relating to any investigation, litigation or proceeding or the preparation of any defense in connection
therewith), in each case arising out of or in connection with or by reason of this Agreement, the other Loan Documents, the Tender Offer, the Merger, or the other Transactions, or any actual or proposed use of the proceeds of each of the Facilities,
except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted primarily from the gross negligence or willful misconduct of such Indemnitee or
any of its officers, directors, employees or agents. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section applies, such indemnity shall be effective, whether or not such investigation, litigation or
proceeding is brought by Alcoa, any other Restricted Group Member, Alcan or any of their respective directors, security holders or creditors, an Indemnitee or any other person, or an Indemnitee is 

  

 59 








 
otherwise a party thereto and whether or not the Transactions are consummated. No Indemnitee shall have any liability (whether in contract, tort or
otherwise) to Alcoa, any other Restricted Group Member, Alcan or any of their respective security holders or creditors for or in connection with the Transactions, except to the extent such liability is determined in a final, non-appealable judgment
by a court of competent jurisdiction to have resulted primarily from such Indemnitee’s gross negligence or willful misconduct. In no event, however, shall any Indemnitee be liable on any theory of liability for any special, indirect,
consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings). Each Restricted Group Member hereby waives, releases and agrees (each for itself and on behalf of its Subsidiaries) not to sue
upon any such claim for any special, indirect, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor. 
 (d) The provisions of this Section 10.05 and any other indemnification or other protection provided to any Indemnitee pursuant to this Agreement shall (i) remain operative and in full force and effect
regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment in full of the Obligations, the invalidity or unenforceability of any term or provision of this Agreement, or any
investigation made by or on behalf of the Administrative Agent or Lender and (ii) inure to the benefit of any person that was at the time such claim arose an Indemnitee under this Agreement or any other Loan Document. All amounts due under this
Section 10.05 shall be payable on written demand therefor, but shall be subject to the requirements of reasonableness and documentation as set forth herein. 
 SECTION 10.06. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set
off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or its Affiliates to or for the credit or the account of any Borrower against any
of and all the Obligations of such Borrower (or, in the case of Alcoa, any of and all the Obligations of any Borrower) now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement or otherwise and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

 SECTION 10.07. Applicable Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW
YORK. 
 SECTION 10.08. Waivers; Amendment. (a) No failure or delay of the Administrative Agent or any Lender in exercising any
power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have. No waiver of any
provision of this Agreement or consent to any departure by any Restricted Group Member therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only
in the specific instance and for the purpose for which given. No notice or demand on any Restricted Group Member in any case shall entitle such Restricted Group Member to any further notice or shall entitle such Restricted Group Member or any other
Restricted Group Member to notice or demand in similar or other circumstances. 
  

 60 








 (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to
an agreement or agreements in writing entered into by the Restricted Group Members and the Required Lenders; provided, however, that no such agreement shall (i) decrease the principal amount of, or extend the maturity of any
principal payment date or date for the payment of any interest on any Loan or date fixed for payment of any Unused Commitment Fee, or waive or excuse any such payment or any part thereof, or decrease the rate of interest on any Loan, without the
prior written consent of each Lender affected thereby, (ii) change or extend the Commitment or decrease the Unused Commitment Fee of any Lender without the prior written consent of such Lender, (iii) amend or modify the provisions of
Section 2.15, 2.16, the provisions of Article VIII, the provisions of this Section or the definition of “Ratable Portion”, “Required Canadian/U.S. Lenders”, “Required Lenders”, or “Required U.S.
Lenders” without the prior written consent of each Lender affected thereby or (iv) amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent;
provided, further, that any modification of provisions requiring payments to be applied on a pro rata basis to the U.S. Loans and the Canadian/U.S. Loans shall require the consent of the Required U.S. Lenders and the Required
Canadian/U.S. Lenders. Each Lender and each assignee thereof shall be bound by any waiver, consent, amendment or modification authorized by this Section. 
 SECTION 10.09. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the applicable interest rate, together with all fees and charges which are treated as interest under
applicable law (collectively the “Charges”), as provided for herein or in any other document executed in connection herewith, or otherwise contracted for, charged, received, taken or reserved by any Lender, shall exceed the maximum
lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by such Lender in accordance with applicable law, the rate of interest payable to such Lender, together with all Charges payable to
such Lender, shall be limited to the Maximum Rate. Without limiting the generality of the foregoing in this Section 10.09, and specifically in respect of any Loan made to a Canadian Borrower, if any provision of this Agreement would oblige any
Canadian Borrower(s) to make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate which would result in a receipt by that Lender of “interest” at a “criminal rate” (as
such terms are construed under the Criminal Code (Canada)), then, notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be,
as would not be so prohibited by law or result in a receipt by that Lender of “interest” at a “criminal rate”, such adjustment to be effected, to the extent necessary (but only to the extent necessary), first, by
reducing the amount or rate of future interest required to be paid by the Canadian Borrower(s) to the affected Lender; second, by reducing any fees and other amounts required to be paid by the Canadian Borrower(s) to the affected Lender which would
constitute “interest” for purposes of Section 347 of the Criminal Code (Canada), and thereafter by crediting the Canadian Borrower(s) with an appropriate additional prepayment of its Loan(s) so as to achieve compliance
with the aforesaid Section 347. 
 SECTION 10.10. Entire Agreement. This Agreement and any fee arrangements related hereto
constitute the entire contract between the parties relative to the subject matter hereof. Any previous agreement among the parties with respect to the subject matter hereof is superseded by this Agreement and the fee arrangements related hereto.

 SECTION 10.11. Waiver of Jury Trial. Each party hereto hereby waives, to the fullest extent permitted by applicable law, any right
it may have to a trial by jury in respect of any litigation directly or indirectly arising out of, under or in connection with this Agreement. Each party hereto (a) certifies that no representative, agent or attorney of any other party has
represented, expressly or 

  

 61 








 
otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it and the other
parties hereto have been induced to enter into this Agreement, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.11. 
 SECTION 10.12. Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability
of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 
 SECTION 10.13.
Counterparts. This Agreement may be executed in two or more counterparts, each of which shall constitute an original but all of which when taken together shall constitute but one contract, and shall become effective as provided in
Section 10.03. 
 SECTION 10.14. Headings. Article and Section headings and the Table of Contents used herein are for convenience
of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement. 
 SECTION 10.15. Jurisdiction, Consent to Service of Process. (a) Each Restricted Group Member hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of
any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement
of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this
Agreement shall affect any right that any Lender may otherwise have to bring any action or proceeding relating to this Agreement against any Restricted Group Member or its properties in the courts of any jurisdiction. 
 (b) Each Restricted Group Member hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection
which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New York State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (c) Each
party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner
permitted by law. 
 (d) To the extent that any Restricted Group Member has, or hereafter may be entitled to claim, any immunity (whether
sovereign or otherwise) from suit, jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution or otherwise) with respect to itself, such Restricted Group
Member hereby waives such immunity in respect of its obligations hereunder and any other Loan Document to the fullest extent permitted by applicable law and, without limiting the generality of the foregoing, agrees that the waivers set forth in this
Section 10.15(d) shall be effective to the fullest extent now or hereafter permitted under the Foreign Sovereign Immunities Act of 1976 (as amended, and together with any successor legislation) and are, and are intended to be, irrevocable for
purposes thereof.

 SECTION 10.16. Conversion of Currencies. (a) If, for the purpose of obtaining judgment in any
court, it is necessary to convert a sum due hereunder in dollars into another currency, the parties hereto agree, to the fullest extent that they may legally and effectively do so, that the rate of exchange used shall be that at which in accordance
with normal banking procedures the Administrative Agent could purchase dollars with such other currency in The City of New York, on the Business Day immediately preceding the day on which final judgment is given. 
 (b) The obligation of each Restricted Group Member in respect of any sum due to any Lender hereunder in dollars shall, to the extent permitted by
applicable law, notwithstanding any judgment in a currency other than dollars, be discharged only to the extent that on the Business Day following receipt of any sum adjudged to be so due in the judgment currency such Lender may in accordance with
normal banking procedures purchase dollars in the amount originally due to such Lender with the judgment currency. If the amount of dollars so purchased is less than the sum originally due to such Lender, such Restricted Group Member agrees, as a
separate obligation and notwithstanding any such judgment, to indemnify such Lender against the resulting loss. 
 SECTION 10.17. National
Security Laws. (a) Each Lender hereby notifies each Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to
obtain, verify and record information that identifies such Borrower, which information includes the name and address of such Borrower and other information that will allow such Lender to identify such Borrower in accordance with the Act. 

(b) Notwithstanding any other provision of this Agreement, no Lender will assign its rights and obligations under this Agreement, or sell
participations in its rights and/or obligations under this Agreement, to any person who is (i) listed on the Specially Designated Nationals and Blocked Persons List maintained by the U.S. Department of Treasury Office of Foreign Assets Control
(“OFAC”) and/or on any other similar list maintained by OFAC pursuant to any authorizing statute, executive order or regulation or (ii) either (A) included within the term “designated national” as defined
in the Cuban Assets Control Regulations, 31 C.F.R. Part 515 or (B) designated under Sections 1(a), 1(b), 1(c) or 1(d) of Executive Order No. 13224, 66 Fed. Reg. 49079 (published September 25, 2001) or similarly designated under any
related enabling legislation or any other similar executive orders. 
 SECTION 10.18. Limitation on Agreements. All agreements between
the Restricted Group Members, the Administrative Agent and each Lender in this Agreement are hereby expressly limited so that in no event shall any of the Loans made on or after the Tender Funding Date or other amounts payable by the Restricted
Group Members under this Agreement from and after the Tender Funding Date be directly or indirectly secured (within the meaning of Regulation U) by Margin Stock. 
 SECTION 10.19. Confidentiality. Each Lender, the Administrative Agent, the Syndication Agent and each Arranger agree to use all reasonable efforts to keep information obtained by it pursuant hereto and the
other Loan Documents (other than such information that is made public by Alcoa or any of its Affiliates) confidential in accordance with such person’s customary practices and agrees that it shall not disclose any such information other than
(a) to such person’s respective Affiliates and their respective employees, representatives and agents that are or are expected to be involved in the evaluation of such information in connection with the Transactions contemplated by this
Agreement and are advised of the confidential nature of such information, (b) to the extent such information presently is or hereafter becomes available to such person on a non-confidential basis from a source other than Alcoa, 

  

 63 








 
the other Borrowers or any other Restricted Group Member or any advisor, agent, employee or other representative thereof in each case that identified itself
as such, (c) to the extent disclosure is required by law, regulation or judicial order or requested or required by bank regulators or auditors, (d) to current or prospective assignees, participants and Approved Funds, grantees described in
Section 10.04, any direct or indirect contractual counterparties to any swap or derivative transaction relating to any Borrower and its Obligations, and to their respective legal or financial advisors, in each case and to the extent such
assignees, participants, Approved Funds, grantees or counterparties are instructed to comply with, and to cause their advisors to comply with, the provisions of this Section 10.19 or other provisions at least as restrictive as the provisions of
this Section 10.19, (e) to any rating agency when required by it, provided, however, that, prior to any such disclosure, such rating agency shall undertake in writing to preserve the confidentiality of any confidential
information relating to Alcoa or the other Restricted Group Members received by it from any of the Agents, any of the Arrangers or any Lender, (f) disclosures in connection with the exercise of any remedies hereunder or under any other Loan
Document and (g) disclosures required or requested by any governmental agency or representative thereof or by the National Association of Insurance Commissioners or pursuant to legal or judicial process. Notwithstanding any other provision in
this Agreement, the Administrative Agent hereby agrees that the Borrowers (and each of their respective officers, directors, employees, accountants, attorneys and other advisors) may disclose to any and all persons, without limitation of any kind,
the U.S. tax treatment and U.S. tax structure of each of the Facilities and the transactions contemplated hereby and all materials of any kind (including opinions and other tax analyses) that are provided to it relating to such U.S. tax treatment
and U.S. tax structure.
