     On July 31, 1998, Alcoa consummated its acquisition of all
of the outstanding shares of common stock (the "Alumax
Transaction") of Alumax Inc., a Delaware corporation ("Alumax").
On March 13, 1998, Alcoa commenced the Alumax Transaction with a
cash tender offer (the "Offer") for one-half of the outstanding
Alumax shares at $50.00 per share.  The Offer expired on June 16,
1998, at which time Alcoa accepted for payment 27,540,00 shares
of Alumax common stock, representing approximately 51% of the
outstanding Alumax common stock.  The Offer was followed by a
merger in which each remaining outstanding share of Alumax common
stock was converted into 0.6975 of a share of Alcoa common stock.
Shares of Alcoa common stock will now be used to fund the Alumax
Inc., 1993 Long Term Incentive Plan and the Alumax Inc., 1995
Employee Equity Ownership Plan.

     The legality of the securities to which this Registration
Statement relates has been passed upon by Denis A. Demblowski,
Senior Counsel of the Company.  Mr. Demblowski is not eligible to

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article V of the By-laws of the Company provides that
the Company shall indemnify, under specified circumstances,
persons who were or are directors, officers or employees of the
Company or who served or serve other business entities at the
request of the Company.  Under these By-law provisions, a person
who is wholly successful in defending a claim will be indemnified
for any reasonable expenses.  To the extent a person is not
successful in defending a claim, reasonable expenses of the
defense and any liability incurred are to be indemnified under
these provisions only where independent legal counsel or other
disinterested person selected by the Board of Directors
determines that such person acted in good faith and in a manner
such person reasonably believed to be in, or not opposed to, the
best interests of the Company, and in addition with respect to
any criminal action or proceeding, had no reasonable cause to
believe the conduct of such person was unlawful.  Any expense
incurred with respect to any claim may be advanced by the Company
if the recipient agrees to repay such amount if it is ultimately
determined that such recipient is not to be indemnified pursuant
to Article V.

     The foregoing By-law provisions generally parallel
Sections 1741 and 1745 of the Pennsylvania Business Corporation
Law ("BCL").  Section 1746 and the By-laws both also provide that
the indemnification provided for therein shall not be deemed
exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.

     Section 1746 of the BCL and the By-laws provide for
increased indemnification protections for directors, officers and 
others.  Indemnification may be provided by Pennsylvania corpora-
tions in any case except where the act or failure to act giving 
rise to the claim for indemnification is determined by a court to 
have constituted willful misconduct or recklessness.

     Section 1713 of the BCL also sets forth a framework
whereby Pennsylvania corporations, with the approval of the
shareholders, may limit the personal liability of directors for
monetary damages except where the act or omission giving rise to
a claim constitutes self-dealing, willful misconduct or
recklessness.  The section does not apply to a director's
responsibility or liability under a criminal or tax statute and
may not apply to liability under Federal statutes, such as the
Federal securities laws.

     The Company's Articles and By-laws were amended by the
shareholders to implement the increased protections made
available to directors under the BCL as described in the
preceding paragraph. Article VIII of the By-laws provides that,
except as prohibited by law, every director of the Company shall
be entitled as of right to be indemnified by the Company for
expenses and any and all liability paid or incurred by such
person by reason of such person being or having been a director
of the Company.  Expenses incurred with respect to any claim may
be advanced by the Company, subject to certain exceptions.  The
shareholders have also approved a form of indemnity agreement.
The Company has entered into such an indemnity agreement with
each of its current directors.

     The Company has purchased a three year liability insurance
policy with an aggregate limit of $100 million, with certain
specified deductible amounts, for liability of directors and
officers and reimbursement to the Company for indemnification
provided to directors and officers.  The policy has an
expiration date of October 1, 2000 and provides liability
insurance and reimbursement coverage for the Company, and its
directors and officers, which is permitted by the laws of
Pennsylvania referred to above.

ITEM 9.  UNDERTAKINGS

     The Company hereby undertakes:

     (1)  To file, during any period in which offers or
sales are being made, a post-effective amendment to this
Registration Statement:

          (i)  To include any prospectus required by Section
10(a)(3) of the Securities Act of 1933;

          (ii)  To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement
(or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change
in the information set forth in the Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume 
of securities offered (if the total dollar value of securities 
offered would not exceed that which was registered) and any 
deviation from the low or high end of the estimated maximum 
offering range may be reflected in the form of prospectus filed 
with the Commission pursuant to Rule 424(b) if, in the aggregate, 
the changes in volume and price represent no more than a 20% 
change in the maximum aggregate offering price set forth in the 
"Calculation of Registration Fee" table in the effective regis-
tration statement;

          (iii)  To include any material information with respect
to the plan of distribution not previously disclosed in the
Registration Statement or any material change to such information
in the Registration Statement;

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) 
of this section do not apply if the information required to be 
included in a post-effective amendment by those paragraphs is 
contained in periodic reports filed with or furnished to the 
Commission by the Registrant pursuant to Section 13 or 
Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement.

     (2)  That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new Registration Statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial
bona fide offering thereof;

     (3)  To remove from registration by means of a post-
effective amendment any of the securities being registered which
remain unsold at the termination of the offering; and

     (4)  That, for purposes of determining any liability
under the Securities Act of 1933, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to section 15(d) of the
Securities Exhange Act of 1934) that is incorporated by reference
in the Registration Statement shall be deemed to be a new
Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the Company pursuant to the
foregoing provisions described in Item 6 above, the Company has
been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities
(other than the payment by the Company of expenses incurred or
paid by a director, officer or controlling person of the Company
in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in
connection with the securities being registered, the Company
will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in
the Act and will be governed by the final adjudication of such
issue.

                               SIGNATURES

     Pursuant to the requirements of the Securities Act of
1933, the Registrant certifies that it meets all of the

ITEM 9.  UNDERTAKINGS

     The Company hereby undertakes:

     (1)  To file, during any period in which offers or
sales are being made, a post-effective amendment to this
Registration Statement:

          (i)  To include any prospectus required by Section
10(a)(3) of the Securities Act of 1933;

          (ii)  To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement
(or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change
in the information set forth in the Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume 
of securities offered (if the total dollar value of securities 
offered would not exceed that which was registered) and any 
deviation from the low or high end of the estimated maximum 
offering range may be reflected in the form of prospectus filed 
with the Commission pursuant to Rule 424(b) if, in the aggregate, 
the changes in volume and price represent no more than a 20% 
change in the maximum aggregate offering price set forth in the 
"Calculation of Registration Fee" table in the effective regis-
tration statement;

          (iii)  To include any material information with respect
to the plan of distribution not previously disclosed in the
Registration Statement or any material change to such information
in the Registration Statement;

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) 
of this section do not apply if the information required to be 
included in a post-effective amendment by those paragraphs is 
contained in periodic reports filed with or furnished to the 
Commission by the Registrant pursuant to Section 13 or 
Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement.

     (2)  That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new Registration Statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial
bona fide offering thereof;

     (3)  To remove from registration by means of a post-
effective amendment any of the securities being registered which
remain unsold at the termination of the offering; and

     (4)  That, for purposes of determining any liability
under the Securities Act of 1933, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to section 15(d) of the
Securities Exhange Act of 1934) that is incorporated by reference
in the Registration Statement shall be deemed to be a new
Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the Company pursuant to the
foregoing provisions described in Item 6 above, the Company has
been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities
(other than the payment by the Company of expenses incurred or
paid by a director, officer or controlling person of the Company
in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in
connection with the securities being registered, the Company
will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in
the Act and will be governed by the final adjudication of such
issue.

                               SIGNATURES

     Pursuant to the requirements of the Securities Act of
1933, the Registrant certifies that it meets all of the

Registration Statement to be signed on its behalf by the
