                  28, 2000 (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),  THE  CHASE
                  MANHATTAN   BANK,   a  New  York   banking   corporation,   as
                  Administrative  Agent for the  Lenders,  and CHASE  SECURITIES
                  INC., as Lead Arranger and Book Manager.

            Alcoa and the Borrowing  Subsidiaries  have requested the Lenders to
extend  credit in order to enable them,  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$510,000,000. 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.


<PAGE>



            "Administrative  Agent" shall mean The Chase  Manhattan  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.


<PAGE>


            "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 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 Eurodollar 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:

            Category 1                    Percentage
            ----------                    ----------

             AA-/Aa3                        .1150%
            or above

            Category 3

              A/A2                          .1225%

              A-/A3                         .1300%



<PAGE>


            Category 5

             BBB/Baa2                       .2000%

            Category 6

             BBB-/Baa3                      .2500%
             or below

            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,  to the extent  determined  by reference to such Index Debt,
shall be based on the Category  corresponding to the higher 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
recently  in effect  prior to such  change or  cessation  shall be  employed  in
determining the Applicable Margin.


<PAGE>


            "Assessment  Rate" shall mean for any date the annual rate  (rounded
upwards,  if necessary,  to the next 1/100 of 1%) most recently estimated by the

Federal  Deposit  Insurance  Corporation  (or any  successor)  for such date for
insurance by such  Corporation  (or such  successor)  of time  deposits  made in
dollars at the Administrative Agent's domestic offices.

            "Assignment and Acceptance"  shall mean an assignment and acceptance

ARTICLE II.  THE CREDITS



<PAGE>


            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,  reduced or increased  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 Eurodollar  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  Eurodollar  Loans  of any  Lender  being  made  to the  Borrowers  and
outstanding under this Agreement at any one time. For purposes of the foregoing,
Loans having different Interest Periods,  regardless of whether they commence on
the same date, shall be considered separate Loans.


<PAGE>


            (c) Except as otherwise  provided in Section 2.10, each Lender shall
make each Loan that is (A) an ABR Loan or (B) a Eurodollar  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 1:00 p.m., New York City time, and the  Administrative  Agent shall by 3:00
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 date
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.


<PAGE>


            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  Eurodollar
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 Eurodollar
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
Eurodollar  Borrowing,  the Interest Period with respect thereto. If no election
as to the Type of Borrowing is specified in any such notice,  then the requested
Borrowing  shall be an ABR Borrowing.  If no Interest Period with respect to any
Eurodollar  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.


<PAGE>


            (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.


<PAGE>


            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 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 provided for in the Engagement Letter (the "Engagement Fees")
at the times provided therein.

            (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  Eurodollar  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.


<PAGE>


            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 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  Eurodollar  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  Eurodollar  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  Eurodollar  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.



<PAGE>


            (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 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.


<PAGE>


            (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.


<PAGE>


            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  Eurodollar  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 Eurodollar 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 Eurodollar 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.

            (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.


<PAGE>


            (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.

            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 Eurodollar  Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written or telecopy notice to Alcoa and the  Administrative  Agent,  such Lender
may:

                  (i) declare that Eurodollar  Loans will not thereafter be made
            by such Lender hereunder,  whereupon any request by a Borrower for a
            Eurodollar  Borrowing  shall,  as to such Lender  only,  be deemed a
            request  for  an  ABR  Loan  unless   such   declaration   shall  be
            subsequently withdrawn; and


<PAGE>


                  (ii) require that all outstanding  Eurodollar Loans made by it
            be converted to ABR Loans, in which event all such Eurodollar  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  Eurodollar  Loans that would have been made by such Lender
or the  converted  Eurodollar  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 Eurodollar Loans.

            (b) For purposes of this Section  2.13, a notice by any Lender shall
be  effective  as to each  Eurodollar  Loan,  if lawful,  on the last day of the
Interest  Period  applicable  to such  Eurodollar  Loan; in all other cases such
notice shall be effective on the date of receipt.


<PAGE>


            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 Eurodollar  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  Eurodollar
Loan.  Such loss or  reasonable  expense  shall  include an amount  equal to the
excess,  if any, as  reasonably  determined  by such Lender,  of (i) its cost of
obtaining the funds for the Loan being paid, prepaid, 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.


<PAGE>


            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  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 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.


<PAGE>


            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  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").


<PAGE>


            (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).


<PAGE>


            (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 1001, Form
4224, W8EBN, or and 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 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  specified in 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.


<PAGE>


            (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.

            (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).


<PAGE>


            (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.



<PAGE>


            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.


<PAGE>


            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, 1999,  and the related  consolidated  statements of income and cash flow for
the year then ended,  all  examined  and  certified  by  PricewaterhouseCoopers,
L.L.P.  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 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, 1999.


<PAGE>


            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.


<PAGE>


            (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 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.


<PAGE>


            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.



<PAGE>


            SECTION 3.18. Year 2000 Computer Systems Compliance.  As of the date
of this Agreement,  there has not occurred, and Alcoa does not expect that there
will occur,  any material  disruption in the  operations or business  systems of
Alcoa or its  Subsidiaries,  taken as a whole,  resulting  from the inability of
computer systems of Alcoa and its Subsidiaries or equipment  containing embedded
microchips to recognize or properly process dates in or following the year 2000.

ARTICLE IV. CONDITIONS OF EFFECTIVENESS, LENDING AND DESIGNATION OF BORROWING

the  sponsor  of a  Multiemployer  Plan  that  such  Multiemployer  Plan  is  in
reorganization or is being terminated,  within the meaning of Title IV of ERISA,
if solely as a result of such reorganization or termination the aggregate annual
contributions  of such Borrower and its ERISA  Affiliates  to all  Multiemployer

exceeding $25,000,000;

            (m) one or more  judgments  for the payment of money in an aggregate

$50,000,000  to levy upon assets or properties of any Borrower or any Subsidiary
of a Borrower to enforce any such judgment; or

            (n)  Any  "Event  of  Default"  as  defined  in the  364-Day  Credit

<PAGE>


then, and in every such event (other than an event described in paragraph (g) or
(h) above), and at any time thereafter during the continuance of such event, the
Administrative Agent, at the request of the Required Lenders,  shall, by written
notice to Alcoa,  take either or both of the following  actions,  at the same or
different times: (i) terminate the Commitments,  and (ii) declare the Loans then
outstanding  to be forthwith due and payable in whole or in part,  whereupon the
principal of the Loans so declared to be due and payable,  together with accrued
interest thereon and any unpaid accrued Fees and all other  liabilities  accrued
hereunder, shall become forthwith due and payable, without presentment,  demand,
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
unpaid  accrued  Fees  and  all  other  liabilities  accrued  hereunder,   shall
automatically become due and payable,  without presentment,  demand,  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.

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.


<PAGE>


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


<PAGE>


            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



<PAGE>


            In  order  to  expedite  the   transactions   contemplated  by  this
Agreement,  The  Chase  Manhattan  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  specifically  delegated  to such  Agent by the  terms  and
provisions  hereof,  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.

            None of the Administrative Agent or any of its directors,  officers,
employees  or agents  shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct,  or
be  responsible  for any  statement,  warranty or  representation  herein or the
contents of any document  delivered in  connection  herewith,  or be required to
ascertain or to make any inquiry concerning the performance or observance by any
Borrower of any of the terms,  conditions,  covenants  or  agreements  contained
herein. The Administrative  Agent shall not be responsible to the Lenders or any
assignee thereof for the due execution, genuineness, validity, enforceability or
effectiveness  of  this  Agreement  or  other  instruments  or  agreements.  The
Administrative  Agent  shall in all  cases  be fully  protected  in  acting,  or
refraining from acting,  in accordance with written  instructions  signed by the
Required Lenders and, except as otherwise  specifically  provided  herein,  such
instructions and any action or inaction  pursuant hereto shall be binding on all
the  Lenders and each  assignee of any such  Lender.  The  Administrative  Agent
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.


<PAGE>


            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).  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),  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.


<PAGE>


            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 documentation agent has no
liability  hereunder  as a  documentation  agent other than in its capacity as a
Lender.

<PAGE>


            (c) By executing and  delivering an Assignment and  Acceptance,  the

appropriate at the time,  continue to make its own credit decisions in taking or
not  taking  action  under  this  Agreement;  (vi) such  assignee  appoints  and
authorizes the  Administrative  Agent to take such action as agent on its behalf
and to  exercise  such  powers  under this  Agreement  as are  delegated  to the
Administrative  Agent by the terms  hereof,  together  with  such  powers as are
reasonably  incidental  thereto;  and (vii) such  assignee  agrees  that it will
perform in accordance with their terms all the obligations which by the terms of
this Agreement are required to be performed by it as a Lender.

            (d) The  Administrative  Agent,  on  behalf of and  solely  for this
purpose as an agent for the  Borrowers,  shall maintain at one of its offices in
The City of New York a copy of each  Assignment and  Acceptance  delivered to it
and a register for the  recordation  of the names and  addresses of the Lenders,
and the Commitment of, and principal  amounts 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 any Borrower and any
Lender  at any  reasonable  time and from  time to time  upon  reasonable  prior
notice.

            (e) Upon its receipt of a duly  completed  Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire

Lender  hereunder),  the processing and recordation fee referred to in paragraph
(b) above and, if required,  the written consent of Alcoa and the Administrative
Agent to such  assignment,  the  Administrative  Agent  shall  (i)  accept  such
Assignment and Acceptance,  (ii) record the information contained therein in the
Register  and (iii) give prompt  notice  thereof to the  Lenders  and Alcoa.  No
assignment shall be effective unless recorded in the Register.


<PAGE>


            (f) Each  Lender may  without  the  consent of any  Borrower  or the
Administrative  Agent sell participations to one or more banks or other entities
in  all  or a  portion  of its  rights  and  obligations  under  this  Agreement
(including  all or a  portion  of its  Commitment  and the  Loans  owing to it);
provided, however, that (i) such Lender's obligations under this Agreement shall
remain unchanged,  (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations,  (iii) the participating
banks or other entities shall be entitled to the benefit of the cost  protection
provisions  contained in Sections  2.12,  2.14 and 2.18 to the same extent as if
they were Lenders and (iv) 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,  and
such  Lender  shall  retain  the sole right to enforce  the  obligations  of the
Borrowers  relating to the Loans and to approve any amendment,  modification  or
waiver of any provision of this Agreement  (provided that the participating bank
or  other  entity  may  be  provided  with  the  right  to  approve  amendments,
modifications  or waivers  affecting  it with respect to (A) any decrease in the
Fees payable hereunder with respect to Loans in which the participating  bank or
other  entity has  purchased  a  participation,  (B) any change in the amount of
principal of, or decrease in the rate at which interest is payable on, the Loans
in which the participating bank or other entity has purchased a participation or
(C) any  extension  of the dates  fixed for  scheduled  payments  of a Fee or of
principal of or interest on the Loans in which the  participating  bank or other
entity has purchased a participation).


<PAGE>


            (g) Any Lender or participant may, in connection with any assignment
or  participation  or  proposed  assignment  or  participation  pursuant to this
Section 10.04,  disclose to the assignee or participant or proposed  assignee or
participant any information relating to any Borrower furnished to such Lender by
or on  behalf  of such  Borrower;  provided,  however,  that,  prior to any such
disclosure  of  information  designated  by Alcoa  as  confidential,  each  such
assignee or  participant or proposed  assignee or  participant  shall execute an
agreement whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the  confidentiality  of such confidential  information.
Notwithstanding the foregoing,  no Lender or participant shall disclose any such
information to any person known to it to compete with Alcoa and its Subsidiaries
in any of the  principal  businesses  of Alcoa and its  Subsidiaries  taken as a
whole, without the prior written consent of Alcoa.

            (h) Any  Lender  may at any time  assign  all or any  portion of its
rights under this  Agreement to a Federal  Reserve  Bank;  provided that no such
assignment  shall  release a Lender from any of its  obligations  hereunder.  In
order to facilitate  such an assignment to a Federal Reserve Bank, each Borrower
shall, at the request of the assigning  Lender,  duly execute and deliver to the
assigning  Lender a promissory  note or notes  evidencing the Loans made to such
Borrower by the assigning Lender hereunder.

            (i) None of Borrowers  shall assign or delegate any of its rights or
obligations  hereunder;  provided,  however, that 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").


<PAGE>


            (j)  Notwithstanding  anything to the contrary contained herein, any
Lender (a "Granting  Lender") may grant to a special  purpose funding vehicle (a
"SPC"),  identified as a SPC in writing from time to time by the Granting Lender
to the  Administrative  Agent and Alcoa and  being  either an  Affiliate  of the
Granting Lender or an entity approved by Alcoa and the Administrative Agent, the
option to provide to the Borrower all or any part of any Loan that such Granting
Lender would  otherwise  be  obligated to make to the Borrower  pursuant to this
Agreement; provided that (i) nothing herein shall constitute a commitment by any
SPC to make any Loan and (ii) if a SPC elects  not to  exercise  such  option or
otherwise  fails to provide all or any part of such Loan,  the  Granting  Lender
shall be obligated to make such Loan pursuant to the terms hereof. The making of
a Loan by a SPC hereunder shall utilize the Commitment of the Granting Lender to
the same extent,  and as if, such Loan were made by such Granting  Lender.  Each
party  hereto  hereby  agrees that no SPC shall be liable for any  indemnity  or
similar payment  obligation  under this Agreement (all liability for which shall
remain with the Granting  Lender).  In furtherance of the foregoing,  each party
hereto hereby  agrees (which  agreement  shall survive the  termination  of this
Agreement)  that,  prior to the date  that is one  year  and one day  after  the
payment in full of all outstanding commercial paper or other senior indebtedness
of any  SPC,  it will  not  institute  against,  or join  any  other  person  in
instituting  against,  such  SPC any  bankruptcy,  reorganization,  arrangement,
insolvency or liquidation proceedings under the laws of the United States or any
State thereof. In addition,  notwithstanding  anything to the contrary contained
in this Section 10.04(j),  any SPC may (i) with notice to, but without the prior
written consent of, the Borrower and the Administrative Agent and without paying
any  processing  fee  therefor,  assign all or a portion of its interests in any
Loans to the Granting Lender or to any financial  institutions  (consented to by
the Borrower and Administrative Agent) providing liquidity and/or credit support
to or for the account of such SPC to support the funding or maintenance of Loans
and (ii) disclose on a confidential basis any non-public information relating to
its Loans to any rating  agency,  commercial  paper  dealer or  provider  of any
surety,  guarantee or credit or liquidity  enhancement to such SPC. This section
may not be amended without the written consent of the SPC.

            SECTION 10.05. Expenses; Indemnity. (a) Alcoa agrees to pay or cause
one or more other Borrowers to pay all  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 fees,  charges  and
disbursements of Cravath,  Swaine & Moore, counsel for the Administrative Agent,
and,  in  connection  with  any  such   enforcement,   the  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, its Affiliates,  each Lender and each of
their  respective  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  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).


<PAGE>


            (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.



<PAGE>


            SECTION 10.08.  Waivers;  Amendment.  (a) No failure or delay of the
Administrative  Agent or any Lender in exercising  any power or right  hereunder
shall operate as a waiver thereof,  nor shall any single or partial  exercise of
any such  right or  power,  or any  abandonment  or  discontinuance  of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the  exercise  of any other  right or power.  The  rights  and  remedies  of the
Administrative  Agent  and the  Lenders  hereunder  are  cumulative  and are not
exclusive of any rights or remedies which they would  otherwise  have. No waiver
of any  provision of this  Agreement or consent to any departure by any 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 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.


<PAGE>


            SECTION 10.10.  Entire Agreement.  This Agreement and the Engagement
Letter  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  Engagement
Letter.  Nothing  in this  Agreement  or the  Engagement  Letter,  expressed  or
implied,  is intended to confer upon any party other than the parties hereto and
thereto any rights,  remedies,  obligations or liabilities under or by reason of
this Agreement or the Engagement Letter.

            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, 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.


<PAGE>


            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.


<PAGE>


            (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.

April 28, 2000


The  Chase  Manhattan  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 Secretary and a Senior Counsel of Alcoa Inc. ("Alcoa") and in such capacity
have  represented  Alcoa in  connection  with  the  Five-Year  Revolving  Credit
Agreement  dated as of April 28, 2000 (the  "Agreement"),  among Alcoa,  certain
subsidiaries  of  Alcoa,  the  Lenders  and The  Chase  Manhattan  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  lawyers  who report to me or  through  other  counsel,  the
originals  or  conformed  copies  of  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.


<PAGE>


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.

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
Government  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.


<PAGE>


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,



                                        Denis A. Demblowski
