                    364-DAY REVOLVING CREDIT AGREEMENT dated as of April 25,
               2003 (as the same may be amended, modified or supplemented from
               time to time, the "Agreement"), among ALCOA INC., a Pennsylvania
               corporation ("Alcoa"), the Lenders (such term and each other
               capitalized term used but not defined herein having the meaning
               ascribed thereto in Article I), and JPMORGAN CHASE BANK, a New
               York banking corporation, as Administrative Agent for the
               Lenders.

          Alcoa and the Borrowing Subsidiaries have requested the Lenders to
extend credit in order to enable Alcoa and the Borrowing Subsidiaries, subject
to the terms and conditions of this Agreement, to borrow on a revolving basis,
at any time and from time to time prior to the Maturity Date, an aggregate
principal amount at any time outstanding not in excess of US$2,000,000,000. The
proceeds of such borrowings are to be used to provide working capital and for
other general corporate purposes, including but not limited to the support of
Alcoa's commercial paper program. The Lenders are willing to extend such credit
to Alcoa and the Borrowing Subsidiaries on the terms and subject to the
conditions set forth herein.

          Accordingly, the Borrowers, the Lenders and the Administrative Agent
agree as follows:

                                   ARTICLE I

                          DEFINITIONS AND CONSTRUCTION

          SECTION 1.01. Defined Terms. As used in this Agreement, the following
terms shall have the meanings set forth below:

          "ABR Borrowing" shall mean a Borrowing comprised of ABR Loans.

          "ABR Loan" shall mean any Loan bearing interest at a rate determined
by reference to the Alternate Base Rate in accordance with the provisions of
Article II.

          "Administrative Agent" shall mean JPMorgan Chase Bank, a New York
banking corporation, in its capacity as administrative agent for the Lenders
hereunder.

          "Administrative Questionnaire" shall mean an Administrative
Questionnaire in the form of Exhibit B.

          "Affiliate" shall mean, when used with respect to a specified person,
another person that directly, or indirectly through one or more intermediaries,
Controls or is Controlled by or is under common Control with the person
specified.

          "Alternate Base Rate" shall mean, for any day, a rate per annum
(rounded upwards, if necessary, to the next 1/16 of 1%) equal to the greatest of
(a) the Prime Rate in effect on such day, (b) the Base CD Rate in effect on such
day plus 1% and (c) the

<PAGE>

                                                                               2

Federal Funds Effective Rate in effect on such day plus 1/2 of 1%. For purposes
hereof, "Prime Rate" shall mean the rate of interest per annum publicly
announced from time to time by the Administrative Agent as its prime rate in
effect at its principal office in New York City; each change in the Prime Rate
shall be effective on the date such change is publicly announced as being
effective. "Base CD Rate" shall mean the sum of (a) the product of (i) the
Three-Month Secondary CD Rate and (ii) Statutory Reserves and (b) the Assessment
Rate. "Three-Month Secondary CD Rate" shall mean, for any day, the secondary
market rate for three-month certificates of deposit reported as being in effect
on such day (or, if such day shall not be a Business Day, the next preceding
Business Day) by the Board through the public information telephone line of the
Federal Reserve Bank of New York (which rate will, under the current practices
of the Board, be published in Federal Reserve Statistical Release H.l5(519)
during the week following such day), or, if such rate shall not be so reported
on such day or such next preceding Business Day, the average of the secondary
market quotations for three month certificates of deposit of major money center
banks in New York City received at approximately 10:00 a.m., New York City time,
on such day (or, if such day shall not be a Business Day, on the next preceding
Business Day) by the Administrative Agent from three New York City negotiable
certificate of deposit dealers of recognized standing selected by it. "Federal
Funds Effective Rate" shall mean, for any day, the weighted average of the rates
on overnight Federal funds transactions with members of the Federal Reserve
System arranged by Federal funds brokers, as published on the next succeeding
Business Day by the Federal Reserve Bank of New York, or, if such rate is not so
published for any day which is a Business Day, the average of the quotations for
the day of such transactions received by the Administrative Agent from three
Federal funds brokers of recognized standing selected by it. If for any reason
the Administrative Agent shall have determined (which determination shall be
conclusive absent manifest error) that it is unable to ascertain the Base CD
Rate or the Federal Funds Effective Rate or both for any reason, including the
inability of the Administrative Agent to obtain sufficient quotations in
accordance with the terms thereof, the Alternate Base Rate shall be determined
without regard to clause (b) or (c), or both, of the first sentence of this
definition, as appropriate, until the circumstances giving rise to such
inability no longer exist. Any change in the Alternate Base Rate due to a change
in the Prime Rate, the Three-Month Secondary CD Rate or the Federal Funds
Effective Rate shall be effective on the effective date of such change in the
Prime Rate, the Three-Month Secondary CD Rate or the Federal Funds Effective
Rate, respectively.

          "Applicable Margin" shall mean, with respect to the LIBOR Loans
comprising any Borrowing, the applicable percentage set forth below based upon
the ratings by S&P and Moody's applicable on such date to the Index Debt:

<PAGE>

                                                                               3

Category 1   Percentage
----------   ----------
  AA-/Aa3
 or above      .1000%

Category 2
----------
   A+/A1       .1425%

Category 3
----------
   A/A2        .1900%

Category 4
----------
   A-/A3       .4350%

Category 5
----------
 BBB/Baa2      .6600%

Category 6
----------
 BBB-/Baa3
 or below      .8600%

          For purposes of the foregoing, (i) if neither Moody's nor S&P shall
have in effect a rating for any Index Debt (other than by reason of the
circumstances referred to in the last sentence of this definition), then both
such rating agencies shall be deemed to have established ratings for such Index
Debt in Category 6; (ii) if only one of Moody's and S&P shall have in effect a
rating for any Index Debt, then the Applicable Margin, to the extent determined
by reference to such Index Debt, shall be determined on the basis of such
rating; (iii) if the ratings established or deemed to have been established by
Moody's or S&P for any Index Debt shall fall within different Categories, the
Applicable Margin shall be based on the Category corresponding to the higher
rating unless the ratings differ by two or more Categories, in which case the
Applicable Margin will be based upon the Category one level above the Category
corresponding to the lower rating; and (iv) if any rating established or deemed
to have been established by Moody's or S&P shall be changed (other than as a
result of a change in the rating system of Moody's or S&P), such change shall be
effective as of the date on which it is first announced by the applicable rating
agency. Each change in the Applicable Margin shall apply during the period
commencing on the effective date of such change and ending on the date
immediately preceding the effective date of the next such change. If the rating
system of Moody's or S&P shall change, or if any such rating agency shall cease
to be in the business of rating corporate debt obligations, Alcoa and the
Lenders shall negotiate in good faith to amend the references to specific
ratings in this definition to reflect such changed rating system or the
non-availability of ratings from such rating agency, and pending the
effectiveness of any such amendment, the ratings of such rating agency most

have in effect a rating for the Index Debt (other than by reason of the
circumstances referred to in the last sentence of this definition), then both
such rating agencies shall be deemed to have established ratings in Category 6;
(ii) if only one of Moody's and S&P shall have in effect a rating for the Index
Debt, then the Facility Fee Percentage shall be determined on the basis of such
rating; (iii) if the ratings established or deemed to have been established by
Moody's or S&P for any Index Debt shall fall within different Categories, the
Facility Fee Percentage shall be based on the Category corresponding to the
higher rating unless the ratings differ by two or more Categories, in which case
the Facility Fee Percentage will be based upon the Category one level above the
Category corresponding to the lower rating; and (iv) if any rating established
or deemed to have been established by Moody's or S&P shall be changed (other
than as a result of a change in the rating system of Moody's or S&P), such
change shall be effective as of the date on which it is first announced by the
applicable rating agency. Each change in the Facility Fee Percentage shall apply
during the period commencing on the effective date of such change and ending on
the date immediately preceding the effective date of the next such change. If
the rating system of Moody's or S&P shall change, or if either of such rating
agencies shall cease to be in the business of rating corporate debt obligations,
Alcoa and the Lenders shall negotiate in good faith to amend the references to
specific ratings in this definition to reflect such changed rating system or the
non-availability of ratings from such rating agency, and pending the
effectiveness of any such amendment, the ratings of

                                   ARTICLE II

                                   THE CREDITS

          SECTION 2.01. Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make revolving credit loans in dollars
(the "Loans") to Alcoa and the Borrowing Subsidiaries, at any time and from time
to time on or after the Effective Date and until the earlier of the Maturity
Date and the termination of the Commitment of such Lender in accordance with the
terms hereof; provided, however, that (i) after giving effect to any Loan, the
aggregate principal amount of the outstanding Loans shall not exceed the Total
Commitment and (ii) at all times the aggregate principal amount of all
outstanding Loans made by each Lender shall equal its Pro Rata Percentage of the
aggregate principal amount of all outstanding Loans. The Commitment of each
Lender is set forth on Schedule 2.01 to this Agreement. Such Commitment may be
terminated or reduced from time to time pursuant to Section 2.09. Within the
limits set forth in the preceding sentence, the Borrowers may borrow, pay or
prepay and reborrow Loans on or after the Effective Date and prior to the
Maturity Date, subject to the terms, conditions and limitations set forth
herein.

          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 $10,000,000 (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 or ABR
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 five
separate LIBOR Loans of any Lender being made to the Borrowers and outstanding
under this Agreement at any one time. For

<PAGE>

                                                                              14

purposes of the foregoing, Loans having different Interest Periods, regardless
of whether they commence on the same date, shall be considered separate Loans.

          (c) Except as otherwise provided in Section 2.10, each Lender shall
make each Loan that is (A) an ABR 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 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 an ABR 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 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 a LIBOR Borrowing or an ABR
Borrowing; (ii) the date of such Borrowing (which shall be a Business Day) and
the amount thereof; and (iii) if such Borrowing is to be a LIBOR Borrowing, the
Interest Period with respect thereto. If no election as to the Type

<PAGE>

                                                                              15

of Borrowing is specified in any such notice, then the requested Borrowing shall
be an ABR 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. If a Borrower shall not have given notice in accordance with this
Section 2.03 of its election to refinance a Borrowing prior to the end of the
Interest Period in effect for such Borrowing, then the Borrower shall (unless
such Borrowing is repaid at the end of such Interest Period) be deemed to have
given notice of an election to refinance such Borrowing with an ABR Borrowing.
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.

          SECTION 2.04. Evidence of Debt; Repayment of Loans. (a) The
outstanding principal balance of each Loan shall be payable on the earlier of
the last day of the Interest Period applicable to such Loan or 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 to Alcoa or any Borrowing Subsidiary, the Borrower shall deliver such
a note, satisfactory to the Administrative Agent, payable to such Lender and its
registered assigns, 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 registered assigns.

          SECTION 2.05. Fees. (a) Alcoa will pay to each Lender, through the
Administrative Agent, on the last day of March, June, September and December in
each year, and on the date on which the Commitment of such Lender shall be
terminated as provided herein, a facility fee (the "Facility Fee") at a rate per
annum equal to the Facility

<PAGE>

                                                                              16

Fee Percentage from time to time in effect on the aggregate amount of the
Commitment of such Lender, whether used or unused, from time to time in effect
during the preceding quarter (or shorter period commencing with the date hereof
or ending with the Maturity Date or the date on which the Commitment of such
Lender shall be terminated). All Facility Fees shall be computed on the basis of
the actual number of days elapsed in a year of 360 days. The Facility Fee due to
each Lender shall commence to accrue on the date hereof and shall cease to
accrue on the date on which the Commitment of such Lender shall be terminated as
provided herein.

          (b) Alcoa agrees to pay to the Administrative Agent, for its own
account, the fees payable in the amounts and at the times separately agreed upon
between Alcoa and the Administrative Agent.

          (c) All fees 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 fees shall not be refundable except in the
case of an error which results in the payment of fees in excess of those 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.

          SECTION 2.06. Interest on Loans. (a) Subject to the provisions of
Section 2.07, the unpaid principal amount of the Loans comprising each ABR
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 Alternate Base Rate is determined by reference to the Prime Rate and over a
year of 360 days at all other times) at a rate per annum equal to the Alternate
Base Rate.

          (b) Subject to the provisions of Section 2.07, 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
Alternate 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.

          SECTION 2.07. 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

<PAGE>

                                                                              17

applicable to such Loan as provided in Section 2.06 plus 2% per annum, or (b) in
the case of any other amount, the rate applicable to ABR Borrowings plus 2% per
annum.

          SECTION 2.08. 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 the relevant Borrower and 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 2.10 shall, until the
Administrative Agent shall have advised the Borrowers and the Lenders that the
circumstances giving rise to such notice no longer exist, be deemed to be a
request for an ABR Borrowing. Each determination by the Administrative Agent
hereunder shall be conclusive absent manifest error.

          SECTION 2.09. Termination and Reduction of Commitments. (a) The
Commitments shall be automatically terminated on the Maturity Date.

          (b) Upon at least 10 Business Days' prior irrevocable, written or
telecopy notice to the Administrative Agent, Alcoa may at any time in whole
permanently terminate, or from time to time in part permanently reduce, the
Total Commitment; provided, however, that (i) each partial reduction shall be in
an integral multiple of $1,000,000 and in a minimum principal amount of
$10,000,000 and (ii) the Total Commitment shall not be reduced to an amount that
is less than the aggregate principal amount of the outstanding Loans (after
giving effect to any simultaneous prepayment pursuant to Section 2.11).

          (c) Each reduction in Commitments hereunder shall be made ratably
among the Lenders in accordance with each such Lender's Pro Rata Percentage of
the Total Commitment. Alcoa shall pay to the Administrative Agent for the
account of the applicable Lenders, on the date of each such termination or
reduction, the Facility Fees on the amount of the Commitments so terminated or
reduced accrued to the date of such termination or reduction.

          SECTION 2.10. Refinancings. Any Borrower may refinance all or any part
of any Loan made to it with a Loan of the same or a different Type made pursuant
to the same Commitments, subject to the conditions and limitations set forth in
this Agreement. Any Borrowing or part thereof so refinanced shall be deemed to
have been repaid or prepaid in accordance with Section 2.04 or 2.11, as
applicable, with the proceeds of a new Borrowing; and the proceeds of the new
Borrowing, to the extent they do not exceed the principal amount of the
Borrowing being refinanced, shall not be paid

<PAGE>

                                                                              18

by the applicable Lenders to the Administrative Agent or by the Administrative
Agent to the applicable Borrower pursuant to Section 2.02(c).

          SECTION 2.11. Prepayment. (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 partial prepayment shall be
in an amount which is an integral multiple of $1,000,000 and not less than
$10,000,000.

          (b) On the date of any termination or reduction of any Commitments
pursuant to Section 2.09, 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 the Total Commitment.

          (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 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 2.14 but
otherwise without premium or penalty. All prepayments under this Section 2.11
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

          SECTION 2.12. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision herein other than Section 2.14(c), 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 change the basis of taxation of payments to any Lender of
the principal of or interest on any LIBOR Loan made by such Lender or any fees
or other amounts payable hereunder (other than changes in respect of taxes
imposed on the overall net income of such Lender by the jurisdiction in which
such Lender has its principal office or by any political subdivision or taxing
authority therein), or 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 such Lender (except any such reserve
requirement which is reflected in the LIBO Rate or the Base CD Rate) 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 deemed 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.

                                                                              19

          (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 10 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 2.12 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 2.12 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 2.12 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.

                                                                              20

          SECTION 2.13. Change in Legality. (a) Notwithstanding any other
provision herein other than Section 2.14(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 an ABR Loan unless
     such declaration shall be subsequently withdrawn; and

          (ii) require that all outstanding LIBOR Loans made by it be converted
     to ABR 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 2.13, 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 2.14. Indemnity. Alcoa shall indemnify or cause the other
Borrowers to indemnify each Lender against any loss or expense 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 or refinance any Loan hereunder after
irrevocable notice of such borrowing or refinancing has been given pursuant to
Section 2.03, (c) any payment, prepayment or refinancing 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 2.12 or 2.13, (d) any default in payment or
prepayment of the principal amount of any 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

<PAGE>

                                                                              21

being paid, prepaid, refinanced or not borrowed (assumed to be the LIBO Rate
applicable thereto) for the period from the date of such payment, prepayment,
refinancing or failure to borrow or refinance to the last day of the Interest
Period for such Loan (or, in the case of a failure to borrow or refinance 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 or refinanced 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 2.15. Pro Rata Treatment. Except as required under Section
2.13, each Borrowing, each payment or prepayment of principal of any Borrowing,
each payment of interest on the Loans, each payment of the Facility Fees, each
reduction of 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 applicable Commitments (or, if such Commitments
shall have expired or been terminated, in accordance with the respective
principal amounts of their applicable 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 2.16. 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

<PAGE>

                                                                              22

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 2.17. 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 270 Park Avenue,
New York, New York, 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, 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 2.18. 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
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding taxes imposed
on the net income of the Administrative Agent or any Lender (or any transferee
or assignee thereof, including a participation holder (any such entity a
"Transferee")) and franchise taxes imposed on the Administrative Agent or any
Lender (or Transferee) in each case by the United States or any jurisdiction
under the laws of which the Administrative Agent or any such Lender (or
Transferee) is organized or any political subdivision thereof (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, "Taxes"). If any Borrower shall be
required by law to deduct any 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 2.18) such Lender (or 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 paragraph (a)
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

<PAGE>

                                                                              23

which arise from any payment made hereunder or from the execution, delivery or
registration of, or otherwise with respect to, this Agreement (hereinafter
referred to as "Other Taxes").

          (c) Each Borrower will indemnify each Lender (or Transferee) and the
Administrative Agent for the full amount of Taxes and Other Taxes 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, whether or not such Taxes or Other Taxes were correctly or
legally asserted by the relevant taxing authority or other Governmental
Authority. 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.

          (d) Within 30 days after the date of any payment of 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.

          (e) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.18 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 Alcoa or any Borrowing
Subsidiary 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 2.18(f)) that is organized under the laws of a
jurisdiction outside the United States 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 W8-BEN, Form
W-8ECI, or any other certificate or statement of exemption required by Treasury
Regulation Section 1.1441-1, 1.1441-4 or 1.1441-6(c) or any subsequent version
thereof or successors thereto, properly completed and duly executed by such
Lender (or Transferee) establishing that payment 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 or (ii) totally exempt from United States
Federal withholding tax under a provision of an applicable tax treaty. In
addition, each such Lender (or such Transferee) shall, if legally

<PAGE>

                                                                              24

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 withholding tax, Alcoa or the
Administrative Agent shall withhold such taxes from such payments at the
applicable statutory rate, subject to Section 2.18(a).

          (h) None of the Borrowers shall be required to pay any additional
amounts to any Lender (or Transferee) in respect of United States Federal
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) 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.

          (i) Any Lender (or Transferee) claiming any additional amounts payable
pursuant to this Section 2.18 shall use reasonable efforts (consistent with
legal and regulatory restrictions) to file any certificate or document 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).

          (j) If a Lender (or Transferee) or the Administrative Agent shall
become aware that it may be entitled to receive a refund in respect of Taxes or
Other Taxes as to which it has been indemnified by a Borrower pursuant to this
Section 2.18, it shall promptly notify Alcoa of the availability of such refund
and shall, within 30 days after receipt of a request by Alcoa, apply for such
refund at Alcoa's expense. If any Lender (or Transferee) or the Administrative
Agent receives a refund in respect of any Taxes or Other Taxes as to which it
has been indemnified by a Borrower pursuant to this Section 2.18, it shall
promptly repay such refund to such Borrower (to the extent of amounts that have
been paid by such Borrower under this Section 2.18 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; 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.

<PAGE>

                                                                              25

          (k) Nothing contained in this Section 2.18 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).

          (l) No Borrower shall be required to reimburse any Lender (or
Transferee) or the Administrative Agent with respect to any Tax or Other Tax
unless such Lender, Transferee or the Administrative Agent notifies such
Borrower of the amount of such Tax or Other Tax on or before the second
anniversary of the date such Lender, Transferee or the Administrative Agent pays
such Tax or Other Tax.

          SECTION 2.19. Assignment of Commitments Under Certain Circumstances.
In the event that any Lender shall have delivered a notice or certificate
pursuant to Section 2.12 or 2.13, or a Borrower shall be required to make
additional payments to any Lender under Section 2.18, 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 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.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

          Each Borrower represents and warrants to each of the Lenders with
respect to itself as follows (except that the Borrowing Subsidiaries make no
representations or warranties under Section 3.06 or 3.09):

          SECTION 3.01. Organization. Such Borrower is a corporation duly
organized, validly existing and, where applicable, in good standing under the
laws of its jurisdiction of incorporation and is duly qualified to do business
as a foreign corporation and, where applicable, is in good standing 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. Such Borrower has corporate power and
authority to execute, deliver and carry out the provisions of this Agreement to
which it is a party, to borrow hereunder and to perform its obligations
hereunder and all such action has been duly and validly authorized by all
necessary corporate proceedings on its part.

          SECTION 3.03. Enforceability. This Agreement has been duly executed
and delivered by such Borrower and constitutes the legal, valid and binding
obligation of such Borrower enforceable in accordance to 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 such Borrower's execution and delivery
of this Agreement, the consummation by any Borrower of the transactions
contemplated hereby or such Borrower's performance of or compliance with the
terms and conditions hereof, except as set forth on Schedule 3.04.

          SECTION 3.05. No Conflict. None of the execution and delivery by such
Borrower of this Agreement, the consummation by such Borrower of the
transactions contemplated hereby or performance by such Borrower of or
compliance by such Borrower 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
it is subject, (b) conflict with or result in a breach or default under its
charter or Memorandum and Articles of Association or by-laws, 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 Borrower 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 Borrower.

          SECTION 3.06. Financial Statements. In the case of Alcoa, it has
furnished to the Lenders copies of its consolidated balance sheet as of December
31, 2002, and the related consolidated statements of income and cash flow for
the year then ended, all examined and certified by PricewaterhouseCoopers, LLP.
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 for the periods then ended, all in conformity with
GAAP, subject (in the case of the interim financial statements) to year-end
audit adjustments.

          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.
Such Borrower is not in violation of (i) any term of its charter or Constitution
or by-laws, as applicable, or (ii) any material 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 any Exchange Act Report or otherwise
disclosed on

<PAGE>

                                                                              27

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 it which in the opinion of its counsel is likely to result in
a Material Adverse Effect. Except as set forth in the financial statements
referred to in Section 3.06 or any Exchange Act Report or otherwise disclosed in
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 any of its Subsidiaries which in the opinion of its counsel is
likely to result in a Material Adverse Effect.

          SECTION 3.09. No Material Adverse Change. As of the date of this
Agreement, there has been no material adverse change in the business, assets,
operations or financial condition of itself and its Subsidiaries, taken as a
whole except, in the case of Alcoa and the Borrowing Subsidiaries, as disclosed
in any Exchange Act Report since December 31, 2002.

          SECTION 3.10. Employee Benefit Plans. (a) U.S. Plans. It and each of
its ERISA Affiliates is in compliance in all material respects with the
applicable provisions of ERISA and the regulations and published interpretations
thereunder. No Reportable Event has occurred as to which such Borrower 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 Borrower to the PBGC in an aggregate amount in excess of
$25,000,000. 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
Borrower nor any ERISA Affiliate has incurred any Withdrawal Liability that
would reasonably be expected to result in a Material Adverse Effect. Neither
such Borrower 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 Borrower 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 in all material
respects 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 Borrowers, their
respective Affiliates or any of their directors, officers, employees or agents
has engaged in a transaction which would subject any of the Borrowers, directly
or indirectly, to a material tax or civil penalty which could reasonably be
expected to result in a Material Adverse Effect. With respect to each Foreign
Pension Plan, none of the Borrowers, their respective Affiliates or any of their
directors, officers, employees or agents has engaged in a transaction which
would subject any of the Borrowers, directly or indirectly, to a material tax or
civil penalty which could reasonably be expected to result in a Material Adverse
Effect. With respect to each

<PAGE>

                                                                              28

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 material actions, suits or claims (other than routine
claims for benefits) pending or threatened against any of the Borrowers 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 3.11. Title to Properties; Possession Under Leases. (a) Such
Borrower 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) Such Borrower 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. Such Borrower and its Subsidiaries
enjoy peaceful and undisturbed possession under all such material leases.

          SECTION 3.12. Investment Company Act; Public Utility Holding Company
Act. None of Alcoa or any Borrowing Subsidiary is an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940.
Alcoa is exempted as, and no Borrowing Subsidiary is, a "holding company" as
defined in, or subject to regulation under, the Public Utility Holding Company
Act of 1935.

          SECTION 3.13. Tax Returns. Such Borrower and its Subsidiaries have
filed or caused to be filed all Federal, state, local and foreign tax returns
required to have been filed by it and have paid or caused to be paid all 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 in accordance with
GAAP.

          SECTION 3.14. Compliance with Laws and Agreements. (a) Neither such
Borrower nor any of its 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.

          (b) Neither such Borrower nor any of its 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 3.15. No Material Misstatements. Except for information not
prepared by Alcoa and expressly disclaimed thereby, no report, financial
statement, exhibit or schedule furnished by or on behalf of such Borrower to the
Administrative Agent or any Lender in connection with the negotiation of this
Agreement or included herein or delivered pursuant thereto contained or contains
any material misstatement of fact or omitted or omits to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were or are made, not misleading.

          SECTION 3.16. Federal Reserve Regulations. The proceeds of any Loan
will be used to provide working capital or for other general corporate purposes,
including but not limited to the support of Alcoa's Commercial Paper program. No
part of the proceeds of any Loan to such Borrower will be used, whether directly
or indirectly, and whether immediately, incidentally or ultimately, for any
purpose that entails a violation of any of the Regulations of the Board,
including Regulations U and X.

          SECTION 3.17. No Trusts. Such Borrower is not entering into this
Agreement in its capacity as trustee of any trust.

                                   ARTICLE IV

shall cause its Subsidiaries to, maintain and keep its properties in such
repair, working order and condition, and make or cause to be made all such
needful and proper repairs, renewals and replacements thereto, as in the

provided, however, that nothing in this Section 5.03 shall prevent such Borrower
(or any Subsidiary thereof) from selling, abandoning or otherwise disposing of
any of its respective properties or discontinuing a part of its respective
businesses from time to time if, in the judgment of such Borrower, such sale,
abandonment, disposition or discontinuance is advisable.

          SECTION 5.04. Obligations and Taxes. Each Borrower shall pay its
Indebtedness and other obligations that, if not paid, would result in a Material
Adverse Effect before the same shall become delinquent or in default, and pay

consolidated Subsidiaries to, insure and keep insured, in each case with
reputable insurance companies, so much of its respective properties to such an

     advance or other payments pursuant to any contract or statute or to secure
     any Indebtedness incurred for the purpose of financing all or any part of

     any improvements thereon).

          (b) Notwithstanding paragraph (a) of this Section 6.01 and in addition
to the Liens permitted thereunder, each Borrower and any Restricted Subsidiary

Alcoa and its consolidated Subsidiaries at such time.

          SECTION 6.02. Consolidation, Merger, Sale of Assets, etc. Consolidate

respect of a Borrower

or the failure to make a required payment, there are reasonable grounds (A) for
the termination of such Plan or Plans, or such Foreign Plan or Foreign Plans, by

          (l) any Borrower or any ERISA Affiliate shall have been notified by

contributions of such Borrower and its ERISA Affiliates to all Multiemployer
Plans that are then in reorganization or have been or are being terminated have
been or will be increased over the amounts required to be contributed to such
Multiemployer Plans for their most recently completed plan years by an amount

          (m) one or more judgments for the payment of money in an aggregate
amount in excess of $50,000,000 shall be rendered against any Borrower or any

notice to Alcoa, take either or both of the following actions, at the same or

protest or any other notice of any kind, all of which are hereby expressly
waived by each Borrower, anything contained herein to the contrary
notwithstanding; and in any event described in paragraph (g) or (h) above, the
Commitments of the Lenders shall automatically terminate and the principal of
the Loans then outstanding, together with accrued interest thereon and any

                                  ARTICLE VIII

                                    GUARANTEE

          Alcoa unconditionally and irrevocably guarantees, as a principal
obligor and not merely as a surety, the due and punctual payment and performance
of all Borrowing Subsidiary Obligations. Alcoa further agrees that the Borrowing
Subsidiary 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 Subsidiary Obligation.

          Alcoa waives presentation to, demand of payment from and protest to
any Borrowing Subsidiary of any of the Borrowing Subsidiary 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 (a) the failure of the Administrative Agent or any Lender to
assert any claim or demand or to enforce any right or remedy against any
Borrowing Subsidiary under the provisions of this Agreement or any guarantee;
(b) any extension or renewal of any provision of this Agreement or any
guarantee; or (c) any rescission, waiver, amendment or modification of any of
the terms or provisions of this Agreement or any guarantee or any other
agreement.

          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
Borrowing Subsidiary or any other person.

          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 Subsidiary 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 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, wilful or otherwise, in the performance of the Borrowing Subsidiary
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.

          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
Borrowing Subsidiary to the Administrative Agent or any Lender, or any part
thereof, of principal of or interest on such Borrowing Subsidiary Obligation is
rescinded or must otherwise be restored by the Administrative Agent or any
Lender or any holder of any Borrowing Subsidiary

                                                                              42

Obligation upon the bankruptcy or reorganization of such Borrowing Subsidiary or
otherwise.

          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 Subsidiary 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 Subsidiary Obligation, and thereupon such
Agent shall assign, in any reasonable manner, the amount of the Borrowing
Subsidiary Obligation paid by Alcoa pursuant to this guarantee to Alcoa, such
assignment to be pro tanto to the extent to which the Borrowing Subsidiary
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).

          Upon payment by Alcoa of any sums to the Administrative Agent as
provided above, all rights of Alcoa against the Borrowing Subsidiaries 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 Subsidiary Obligations.

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

          In order to expedite the transactions contemplated by this Agreement,
JPMorgan Chase Bank is hereby appointed to act as the Administrative Agent on
behalf of the Lenders. Each of the Lenders and each assignee of any such Lender
hereby irrevocably authorizes the Administrative Agent to take such actions on
behalf of such Lender or assignee and to exercise such powers as are

together with such actions and powers as are reasonably incidental thereto. The
Administrative Agent is hereby expressly authorized by the Lenders, without
hereby limiting any implied authority, (a) to receive on behalf of the Lenders
all payments of principal of and interest on the Loans and all other amounts due
to the Lenders hereunder, and promptly to distribute to each Lender its proper
share of each payment so received; (b) to give notice on behalf of each of the
Lenders to the relevant Borrower of any Event of Default specified in this
Agreement of which the Administrative Agent has actual knowledge acquired in
connection with its agency hereunder; and (c) to distribute to each Lender
copies of all notices, financial statements and other materials delivered by any
Borrower pursuant to this Agreement as received by such Agent.

refraining from acting, in accordance with written instructions signed by the
Required Lenders and, except as otherwise specifically provided herein, such

shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. None of the
Administrative Agent or any of its directors, officers, employees or agents
shall have any responsibility to any Borrower on account of the failure of or
delay in performance or breach by any other Lender or any Borrower of any of
their respective obligations hereunder or in connection herewith. The
Administrative Agent may execute any and all duties hereunder by or through
agents or employees and shall be entitled to rely upon the advice of legal
counsel selected by it with respect to all matters arising hereunder and shall
not be liable for any action taken or suffered in good faith by it in accordance
with the advice of such counsel.

          The Lenders hereby acknowledge that the Administrative Agent shall not
be under any duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement unless it shall be requested in
writing to do so by the Required Lenders.

          Subject to the appointment and acceptance of a successor
Administrative Agent as provided below, the Administrative Agent may resign at
any time by notifying the Lenders and the Borrowers. Upon any such resignation,
the Required Lenders shall have the right to appoint a successor; provided,
however, that Alcoa has approved such successor (such consent not to be
unreasonably withheld or delayed and not to be required if an Event of Default
exists). If no successor shall have been so appointed by the Required Lenders
and shall have accepted such appointment within 30 days after the retiring
Administrative Agent gives notice of its resignation, then the retiring Agent
may, on behalf of the Lenders, appoint a successor Administrative Agent, subject
to the prior approval of Alcoa (such consent not to be unreasonably withheld or
delayed and not to be required if an Event of Default exists), which shall be a
bank with an office in New York, New York, having total assets in excess of
$10,000,000,000 or an Affiliate of any such bank. Upon the acceptance of any
appointment as the Administrative Agent hereunder by a successor bank, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent and the retiring Agent shall be
discharged from its duties and obligations hereunder. After the Agent's
resignation hereunder the provisions of this Article and Section 10.05 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Administrative Agent.

          With respect to the Loans made by it hereunder, the Administrative
Agent in its individual capacity and not as Agent shall have the same rights and
powers as any other Lender and may exercise the same as though it were not an
Administrative Agent, and such Agent and its Affiliates may accept deposits
from, lend money to and generally engage in any kind of business with any
Borrower or any Subsidiary or other Affiliate of Alcoa as if it were not an
Agent.

          Each Lender agrees (i) to reimburse the Administrative Agent, on
demand, in the amount of its pro rata share (based on its Commitment hereunder)
of any expenses incurred for the benefit of the Lenders by such Agent, including
counsel fees and compensation of agents and employees paid for services rendered
on behalf of the Lenders, which shall not have been reimbursed by the Borrowers
and (ii) to indemnify and hold harmless the Administrative Agent and any of its
directors, officers, employees, agents or Affiliates, on demand, in the amount
of such pro rata share, from and against any and all liabilities, taxes,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by or asserted against it in its capacity as an Administrative
Agent or any of them in any way relating to or arising out of this Agreement or
any action taken or omitted by it or any of them under this Agreement, to the
extent the same shall not have been reimbursed by the Borrowers; provided that
no Lender shall be liable to the Administrative Agent for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or wilful
misconduct of such Agent or any of its directors, officers, employees, agents or
Affiliates.

          Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or other Lender and based on such documents and information
as it shall from time to time deem appropriate, continue to make its own
decisions in taking or not taking action under or based upon this Agreement, any
related agreement or any document furnished hereunder or thereunder.

          Each Lender hereby acknowledges that the syndication and documentation
agents have no liability hereunder as syndication and documentation agents other
than in their capacity as Lenders.

                                                                              46

          SECTION 10.03. Binding Effect. This Agreement shall become effective
when it shall have been executed by Alcoa and the Administrative Agent and when
the Administrative Agent shall have received copies hereof which, when taken
together, bear the signatures of each Lender, and thereafter shall be binding
upon and inure to the benefit of the Borrowers, the Administrative Agent and
each Lender and their respective successors and assigns, except that none of the
Borrowers shall have the right to assign its rights hereunder or any interest
herein without the prior consent of all the Lenders.

          SECTION 10.04. Successors and Assigns; Additional Borrowing
Subsidiaries. (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that (i) the Borrowers may not assign or
otherwise transfer any of their rights or obligations hereunder (except as
provided in Section 10.04(e)) without the prior written consent of each Lender
(and any attempted assignment or transfer by the Borrowers without such consent
shall be null and void) and (ii) no Lender may assign or otherwise transfer its
rights or obligations hereunder except in accordance with this Section. Nothing
in this Agreement, expressed or implied, shall be construed to confer upon any
person (other than the parties hereto, their respective successors and assigns
permitted hereby, Participants (to the extent provided in paragraph (c) of this
Section) and, to the extent expressly contemplated hereby, the Related Parties
of each of the Administrative Agent and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

          (b) (i) Subject to the conditions set forth in paragraph (b)(ii)
below, any Lender may assign to one or more assignees 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); 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, provided that no consent of the
     Administrative Agent shall be required for an assignment to an assignee
     that is a Lender immediately prior to giving effect to such assignment.

          (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 unless each of
     Alcoa and the Administrative Agent otherwise consent, provided that no such
     consent of Alcoa shall be required if an

<PAGE>

                                                                              47

     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" means (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.

          "CLO" means 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 and, to the extent of the interest assigned by 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 2.12,
     2.14, 2.18 and 10.05). Any assignment or transfer by a Lender of rights or
     obligations under this Agreement that does not comply with this Section
     10.04 shall be treated for purposes of this Agreement as a sale by such
     Lender of

<PAGE>

                                                                              48

     a participation in such rights and obligations in accordance with paragraph
     (c) of this Section.

          (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 may 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 (b)
     of this Section and any written consent to such assignment required by
     paragraph (b) of this Section, the Administrative Agent shall (i) accept
     such Assignment and Assumption, (ii) record the information contained
     therein in the Register and (iii) give prompt notice thereof to Alcoa. No
     assignment shall be effective for purposes of this Agreement unless 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 proviso 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 2.12 and 2.18 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

<PAGE>

                                                                              49

Section 10.06 as though it were a Lender, provided such Participant agrees to be
subject to Section 2.16 as though it were a Lender.

          (ii) A Participant shall not be entitled to receive any greater
     payment under Section 2.12 or 2.18 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.

          (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 may designate any wholly-owned Subsidiary to
be a Borrowing Subsidiary upon the completion of the following: (i) each of
Alcoa and such Subsidiary shall have executed and delivered to the
Administrative Agent a Designation of Borrowing Subsidiary and (ii) such
Subsidiary shall have complied with Section 4.03, whereupon (A) such Subsidiary
shall become a party hereto and shall have the rights and obligations of a
Borrowing Subsidiary hereunder and (B) the obligations of such Subsidiary shall
become part of the Borrowing Subsidiary Obligations and the guarantee of Alcoa
pursuant to Article VIII hereof shall apply thereto to the same extent that it
applies to the other Borrowing Subsidiary Obligations, if any (the date on which
any such designation shall occur being called a "Designation Date").

          SECTION 10.05. Expenses; Indemnity. (a) Alcoa agrees to pay or cause
one or more other Borrowers to pay all reasonable out-of-pocket expenses
incurred by the Administrative Agent in connection with the preparation of this
Agreement or in connection with any amendments, modifications or waivers of the
provisions hereof or thereof (whether or not the transactions hereby
contemplated shall be consummated) or incurred by the Administrative Agent or
any Lender in connection with the enforcement of their rights in connection with
this Agreement or in connection with the Loans made hereunder, including the
reasonable fees, charges and disbursements of Cravath, Swaine & Moore, counsel
for the Administrative Agent, and, in connection with any such enforcement, the
reasonable fees, charges and disbursements of any other counsel for the
Administrative Agent or any Lender. Alcoa further agrees to indemnify or cause
one or more other Borrowers to indemnify the Lenders from and hold them harmless
against any documentary taxes, assessments or charges made by any Governmental
Authority by reason of the execution and delivery of this Agreement.

          (b) Alcoa agrees to indemnify or cause one or more other Borrowers to
indemnify the Administrative Agent, each Lender and each of their respective
Affiliates, directors, officers, employees and agents (each such person being
called an "Indemnitee") against, and to hold or cause one or more other
Borrowers to hold each

<PAGE>

                                                                              50

Indemnitee harmless from, any and all losses, claims, damages, liabilities and
related expenses, including reasonable counsel fees, charges and disbursements,
incurred by or asserted against any Indemnitee arising out of, in any way
connected with, or as a result of (i) the execution or delivery of this
Agreement or any agreement or instrument contemplated hereby, the performance by
the parties thereto of their respective obligations thereunder or the
consummation of the transactions contemplated thereby, (ii) the use of the
proceeds of the Loans or (iii) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or wilful
misconduct of such Indemnitee. The Administrative Agent and each Lender agrees
to promptly notify Alcoa of any claims relating to clauses (i), (ii) or (iii) of
the next preceding sentence; provided, however, that any failure to deliver any
such notice shall not relieve Alcoa from its obligations under this paragraph
(b).

          (c) The provisions of this Section 10.05 shall 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 of any of the Loans, 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. All amounts due under this Section 10.05 shall
be payable on written demand therefor.

          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 Borrowing Subsidiary) 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 WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAWS.

          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.

<PAGE>

                                                                              51

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 Borrower 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 Borrower in any case shall entitle such
Borrower to any further notice or shall entitle such Borrower or any other
Borrower to notice or demand in similar or other circumstances.

          (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 Borrowers and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan or date fixed for payment of any Facility 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 Facility Fees of any Lender
without the prior written consent of such Lender, (iii) amend or modify the
provisions of Section 2.14, the provisions of Article VIII, the provisions of
this Section or the definition of "Required Lenders", without the prior written
consent of each Lender or (iv) amend, modify or otherwise affect the rights or
duties of the Administrative Agent hereunder without the prior written consent
of such Agent. 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.

          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 otherwise, that such other party would not,

<PAGE>

                                                                              52

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
Borrower 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
Borrower or its properties in the courts of any jurisdiction.

          (b) Each Borrower 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.

          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 Borrower 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 Borrower agrees, as a
separate obligation and notwithstanding any such judgment, to indemnify such
Lender against the resulting loss.

     IN WITNESS WHEREOF, Alcoa, the Administrative Agent and the Lenders have

April 25, 2003

JPMorgan Chase Bank, as Agent
and each of the Lenders party to the
Agreement referred to below
270 Park Avenue
New York, NY  10017

Ladies and Gentlemen:

I am Counsel of Alcoa Inc. ("Alcoa") and in such capacity have represented Alcoa
in connection with the 364-Day Revolving Credit Agreement dated as of April 25,
2003 (the "Agreement"), among Alcoa, certain subsidiaries of Alcoa, the Lenders
and JPMorgan Chase Bank, as the Administrative Agent. This opinion is rendered
to you pursuant to Section 4.01(a) of the Agreement. Capitalized terms used but
not defined herein shall have the meanings assigned to them in the Agreement.

In rendering the opinion expressed below, I have examined, either personally or
indirectly through other counsel, the originals or conformed copies of the
Agreement and such corporate records, agreements and instruments of Alcoa and
its Subsidiaries, certificates of public officials and of officers of Alcoa and
its Subsidiaries, and such other documents and records as I have deemed
appropriate as a basis for the opinions hereinafter expressed.

Based upon the foregoing and subject to the qualifications stated herein, I am
of the opinion that:

1. Alcoa is a corporation duly organized, validly existing and in good standing
under the laws of the Commonwealth of Pennsylvania and is duly qualified to do
business as a foreign corporation and is in good standing 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.

2. Alcoa has corporate power and authority to execute, deliver and carry out the
provisions of the Agreement, to borrow under the Agreement and to perform its
obligations thereunder and all such action has been duly and validly authorized
by all necessary corporate proceedings on its part.

<PAGE>

                                                                               2

3. The Agreement has been duly executed and delivered by Alcoa and constitutes
the legal, valid and binding obligation of Alcoa enforceable against Alcoa 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.

4. 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 Alcoa's execution and
delivery of the Agreement, the consummation by Alcoa of the transactions
contemplated therein or Alcoa's performance of or compliance with the terms and
conditions thereof, except as set forth on Schedule 3.04 to the Agreement.

5. The execution and delivery by Alcoa of the Agreement, the consummation by
Alcoa of the transactions contemplated thereby or performance by Alcoa of or
compliance with the terms and conditions thereof will not (a) violate any law,
constitution, statute, treaty, regulation, rule, ordinance, order, injunction,
writ, decree or award of any Governmental Authority to which it is subject, (b)
conflict with or result in a breach or default under its charter or by-laws, (c)
to the best of my knowledge, conflict with or result in a breach or default
which is material in the context of the Agreement under any agreement or
instrument to which Alcoa 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 of the
Agreement upon any property or assets of Alcoa, whether now owned or hereafter
acquired.

6. Except as set forth in the financial statements referred to in Section 3.06
of the Agreement, any Exchange Act Report or otherwise disclosed on Schedule
3.08 to the Agreement, there is no pending or, to my knowledge, threatened
proceeding by or before any Governmental Authority against Alcoa or any of its
Subsidiaries which in my opinion is likely to result in a Material Adverse
Effect.

7. Alcoa is not an "investment company" as defined in, or subject to regulation
under, the Investment Company Act of 1940, and Alcoa is exempted as a "holding
company" as defined in the Public Utility Holding Company Act of 1935.

I am a member of the bar of the Commonwealth of Pennsylvania and my opinion is
limited to the laws of the Commonwealth of Pennsylvania and the laws of the
United States of America. I express no opinion herein as to whether a court
would apply New York law to any particular subject matter hereof. To the extent
that the laws of the State of New York or, contrary to the agreement of the
parties, the laws of any other State govern the documents referenced herein, you
may rely on my opinion with respect to such laws to the extent that the laws of
such state or states are substantially the same as the laws of the Commonwealth
of Pennsylvania, as to which sameness I express no opinion.

Very truly yours,
