To the Holders of Common Stock of
Alumax Inc.:
 
                                 INTRODUCTION
 
  AMX Acquisition Corp., a Delaware corporation (the "Purchaser") and a wholly
owned subsidiary of Aluminum Company of America, a Pennsylvania corporation
(the "Parent"), hereby offers to purchase up to 27,000,000 shares of common
stock, par value $.01 per share (the "Shares"), of Alumax Inc., a Delaware
corporation (the "Company"), at a price of $50.00 per Share, net to the seller
in cash, upon the terms and subject to the conditions set forth in this Offer
to Purchase and in the related Letter of Transmittal (which together
constitute the "Offer").
 
  Tendering stockholders who have Shares registered in their own name and who
tender such Shares directly to the Depositary will not be obligated to pay
brokerage fees or commissions or, except as otherwise provided in Instruction
6 of the Letter of Transmittal, stock transfer taxes with respect to the
purchase of Shares by the Purchaser pursuant to the Offer. Stockholders who
hold their Shares through a bank or broker should check with such institution
as to whether there are any fees applicable to a tender of Shares. The
Purchaser will pay all charges and expenses of Credit Suisse First Boston
Corporation ("Credit Suisse First Boston"), which is acting as Dealer Manager
for the Offer (the "Dealer Manager"), First Chicago Trust Company of New York
(the "Depositary") and D.F. King & Co., Inc. (the "Information Agent")
incurred in connection with the Offer. See "Section 16. Fees and Expenses."
 
  THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY (WITH
ONE DIRECTOR ABSENT) APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY, DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER
ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS STOCKHOLDERS
AND RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER, TENDER THEIR SHARES
PURSUANT TO THE OFFER AND ADOPT THE MERGER AGREEMENT.
 
  For a discussion of the Board's recommendation, see "Item 4. The
Solicitation or Recommendation" set forth in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-
9"), which is being mailed to stockholders with this Offer to Purchase.
 
  BT Wolfensohn ("BT Wolfensohn") has delivered to the Board its written
opinion that, as of March 8, 1998, and based upon and subject to the matters
set forth therein the consideration to be received pursuant to the Merger
Agreement by the stockholders of the Company in the Offer and the Merger,
taken together, is fair from a financial point of view to such stockholders. A
copy of the opinion of BT Wolfensohn is contained in the Schedule 14D-9.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE WAITING PERIOD UNDER
THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED,
APPLICABLE TO THE PURCHASE OF THE SHARES PURSUANT TO THE OFFER HAVING EXPIRED
OR BEEN TERMINATED. THE OFFER IS ALSO SUBJECT TO CERTAIN OTHER CONDITIONS SET
FORTH IN THIS OFFER TO PURCHASE. SEE "SECTION 14. CONDITIONS TO THE OFFER."
 
  The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of March 8, 1998 (the "Merger Agreement"), among the Parent, the Purchaser
and the Company. The Merger Agreement provides, among other things, that, upon
the terms and subject to the conditions set forth in the Merger Agreement,
following the purchase of Shares pursuant to the Offer, the Company will be
merged with and into the Purchaser (the "Merger"), which will be the surviving
corporation in the Merger (the "Surviving Corporation"). At the effective time
of the Merger (the "Effective Time"), each issued and outstanding Share (other
than Shares owned by the Parent, the Purchaser, the Company or any of their
respective subsidiaries and Dissenting Shares (as defined in the Merger
Agreement)) will be converted into, and become exchangeable for, the right to
receive: (i) 0.6975 (the "Exchange Ratio") of a share of
<PAGE>
 
common stock, par value $1.00 per share, of the Parent ("Parent Common
Stock"), if the Purchaser purchases at least 27,000,000 Shares or such other
number of Shares which equals the 50% Share Number (as hereinafter defined);
or (ii) a combination of cash and a fraction of a share of Parent Common
Stock, if the Purchaser purchases fewer Shares than the 50% Share Number. The
"50% Share Number" equals that number of Shares which represents an absolute
majority of the excess of (x) the number of issued and outstanding Shares on a
fully diluted basis on the Expiration Date (as hereinafter defined), minus (y)
the total number of Shares issuable upon the exercise of all outstanding
employee/director stock options. The per Share consideration determined
pursuant to clause (i) or clause (ii) above is referred to herein as the
"Merger Consideration."
 
  On the Expiration Date, if the Purchaser purchases all Shares validly
tendered and such number of Shares is less than 27,000,000, then in the Merger
each Share will be converted into the right to receive a prorated amount of
the cash remaining available from the Offer (the "Merger Cash Prorate Amount")
and a fraction of a share of Parent Common Stock (the "Adjusted Exchange
Ratio"), each determined as follows. The Merger Cash Prorate Amount will equal
the U.S. dollar amount (rounded up to the nearest cent) determined by dividing
(1) the product of the per Share amount paid by the Purchaser pursuant to the
Offer times the excess of the 50% Share Number over the number of Shares
purchased by the Purchaser in the Offer by (2) the total number of Shares
outstanding immediately prior to the Effective Time of the Merger minus the
number of Shares owned by the Parent and its subsidiaries immediately prior to
the Effective Time (the "Final Outstanding Number"). The Adjusted Exchange
Ratio will be determined by dividing (3) the product of the 50% Share Number
times .6975 by (4) the Final Outstanding Number. For example, if 26,000,000
Shares were purchased by the Purchaser in the Offer and at the Effective Time
the 50% Share Number were 27,000,000 and the Final Outstanding Number were
28,000,000, then in the Merger each Share (other than those owned by the
Parent or its subsidiaries and Dissenting Shares) would be converted into the
right to receive $1.79 in cash and .6726 of a share of Parent Common Stock.
 
  Pursuant to the Merger Agreement, the Company has advised the Parent that as
of March 8, 1998, 53,458,062 Shares were issued and outstanding, 4,436,350
Shares were issuable upon the exercise of stock options (2,275,355 of which
are currently exercisable), 441,111 Shares were subject to other stock-based
awards and deferred awards, and 190,564 Shares may be issued upon the
occurrence of certain future events, including a change of control. The
27,000,000 Shares to which the Offer relates represent approximately 50% of
the issued and outstanding Shares of the Company.
 
  Because the market price of the shares of Parent Common Stock will fluctuate
and the Exchange Ratio will not be adjusted as a result of such price
fluctuation, the value of the Merger Consideration at the Effective Time may
be greater or less than the $50.00 per Share in cash payable pursuant to the
Offer. Based on the closing price of the Parent Common Stock on the New York
Stock Exchange, Inc. ("NYSE") on March 12, 1998, the value of the fraction of
a share of Parent Common Stock which would have been received in the Merger
had it occurred on such date for each Share pursuant to the Exchange Ratio
would have been $49.78 (assuming 27,000,000 Shares were purchased in the
Offer).
 
  The Merger Agreement provides that, promptly upon the purchase of Shares by
the Purchaser pursuant to the Offer, the Parent will be entitled to designate
that number of directors, rounded up to the next whole number, which equals
the product obtained by multiplying the total number of directors on the
Company's Board (giving effect to the directors designated pursuant to such
provision of the Merger Agreement) by the percentage that the number of Shares
accepted for payment pursuant to the Offer bears to the total number of Shares
then outstanding. In the Merger Agreement, the Company has agreed to increase
the size of the Board or exercise its best efforts to secure the resignations
of incumbent directors or both as is necessary to enable the Parent's
designees to be so elected.
 
  The consummation of the Merger is subject to the satisfaction of certain
conditions, including the approval and adoption of the Merger Agreement and
the transactions contemplated thereby by the affirmative vote of a majority of
the outstanding Shares (the "Company Stockholder Approval"). The Company has
agreed to convene a special meeting of its stockholders (the "Company Special
Meeting") as promptly as practicable for such purpose. If the Company Special
Meeting is held subsequent to the consummation of the Offer and if the
 
                                       2
<PAGE>
 
Purchaser has acquired (pursuant to the Offer or otherwise) a majority of the
outstanding Shares, the Purchaser will have sufficient voting power to approve
and adopt the Merger Agreement and the Merger without the vote of any other
stockholder. If the Company Special Meeting is held prior to the Expiration
Date and the stockholders of the Company fail to approve and adopt the Merger
and the Merger Agreement as required under the applicable provisions of the
Delaware General Corporation Law (the "DGCL"), either the Parent or the
Company may terminate the Merger Agreement, in which event the Offer will be
terminated.
 
  Pursuant to the Merger Agreement, the Company has redeemed the preferred
stock purchase rights outstanding pursuant to the Rights Agreement, dated
February 22, 1996 (the "Rights Agreement"), between the Company and Chemical
Mellon Shareholder Services, L.L.C., as rights agent. Payment of the $.01 per
right redemption price will be made to stockholders of record as of March 18,
1998.
 
  The Merger Agreement is more fully described in "Section 10. Background of
the Offer; Contacts with the Company; the Merger Agreement."
 
  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
  1. Terms of the Offer; Expiration Date. Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of such extension or amendment), the Purchaser will
accept for payment and pay for up to 27,000,000 Shares validly tendered
pursuant to the Offer prior to the Expiration Date and not withdrawn as
permitted by "Section 4. Withdrawal Rights." The term "Expiration Date" means
12:00 midnight, New York City time, on April 9, 1998, unless and until the
Purchaser, in its sole discretion (but subject to the limitations set forth
below), shall have extended the period during which the Offer is open, in
which event the term "Expiration Date" shall mean the latest time and date at
which the Offer, as so extended by the Purchaser, shall expire. If more than
27,000,000 Shares are validly tendered prior to the Expiration Date and not
withdrawn, the Purchaser will accept for payment (and thereby purchase)
27,000,000 Shares, on a pro rata basis, with adjustments to avoid purchases of
fractional Shares, based upon the number of Shares validly tendered on or
prior to the Expiration Date and not withdrawn by each tendering stockholder.
In the event that proration of tendered Shares is required, because of the
difficulty of determining the precise number of Shares properly tendered and
not withdrawn (due in part to the guaranteed delivery procedure described
under "Section 3. Procedures for Accepting the Offer and Tendering Shares"),
the Purchaser does not expect that it will be able to announce the final
results of such proration or pay for any Shares until at least five NYSE
trading days after the Expiration Date. Preliminary results of proration will
be announced by press release as promptly as practicable after the Expiration
Date. Stockholders may obtain such preliminary information from the
Information Agent and may be able to obtain such information from their
brokers. Tendering stockholders will not receive payment for Shares accepted
for payment pursuant to the Offer until the final proration factor is known.
 
  Pursuant to the Merger Agreement, the Purchaser is obligated to purchase up
to 27,000,000 Shares validly tendered and not withdrawn pursuant to the Offer
(or such other number of Shares as equals the 50% Share Number). In the event
that on the Expiration Date 27,000,000 Shares is less than the 50% Share
Number by more than 2% of the then outstanding Shares and the Offer is
scheduled to expire at any time earlier than the tenth business day following
the date the Purchaser's notice of acceptance for payment of Shares pursuant
to the Offer is first published, sent or given, the Offer will be extended
until the expiration of such ten business day period.
 
  Pursuant to the Merger Agreement, the Purchaser may, without the consent of
the Company, (i) extend the Offer if, at the Expiration Date, any of the
conditions to the Purchaser's obligation to accept for payment and to pay for
the Shares are not satisfied or waived, or (ii) extend the Offer for any
period required by any rule, regulation or interpretation of the Securities
and Exchange Commission (the "Commission") or the staff thereof applicable to
the Offer. So long as the Merger Agreement is in effect and the applicable
waiting period under the
 
                                       3
<PAGE>
 
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), has not expired or been terminated, the Purchaser has agreed to extend
the Offer from time to time for a period or successive periods, each not to
exceed ten business days after the previously scheduled Expiration Date. See
"Section 15. Certain Legal Matters and Regulatory Approvals--Antitrust."
During any such extension, Shares previously tendered and not withdrawn will
remain subject to the terms of the Offer, including the right of a tendering
stockholder to withdraw such Shares.
 
  Subject to the applicable regulations of the Commission, the Purchaser also
expressly reserves the right, in its sole discretion (but subject to the terms
and conditions of the Merger Agreement), at any time and from time to time,
(i) to terminate the Offer and not accept for payment any Shares upon the
occurrence of any of the conditions specified in "Section 14. Conditions to
the Offer" immediately prior to the Expiration Date, and (ii) to waive any
condition or otherwise amend the Offer in any respect, by giving oral or
written notice of such termination, waiver or amendment to the Depositary and
by making a public announcement thereof. Subject to the terms of the Merger
Agreement, the Purchaser expressly reserves the right to increase the price
per Share payable in the Offer and to make any other changes in the terms and
conditions of the Offer, except that without the consent of the Company, the
Purchaser will not (i) decrease the price per Share payable pursuant to the
Offer, (ii) reduce the number of Shares to be purchased in the Offer, (iii)
change the form of consideration to be paid in the Offer, (iv) modify any of
the conditions to the Offer set forth in "Section 14. Conditions to the Offer"
in a manner adverse to the holders of Shares, or (v) extend the Offer except
as described above.
 
  Any such extension, delay, termination, waiver or amendment will be followed
as promptly as practicable by public announcement thereof, such announcement
in the case of an extension to be made no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date.
Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), which
require that material changes be promptly disseminated to stockholders in a
manner reasonably designed to inform them of such changes) and without
limiting the manner in which the Purchaser may choose to make any public
announcement, the Purchaser shall have no obligation to publish, advertise or
otherwise communicate any such public announcement other than by issuing a
press release to the Dow Jones News Service.
 
  If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, the Purchaser will extend the Offer to the extent required by Rules
14d-4(c) and 14d-6(d) under the Exchange Act.
 
  The Company has provided the Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase, the related Letter of Transmittal
and other relevant materials will be mailed to record holders of Shares whose
names appear on the Company's stockholder list and will be furnished, for
subsequent transmittal to beneficial owners of Shares, to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the stockholder list or, if applicable, who
are listed as participants in a clearing agency's security position listing.
 
  2. Acceptance for Payment and Payment for Shares. Upon the terms and subject
to the conditions of the Offer (including, if the Offer is extended or
amended, the terms and conditions of any such extension or amendment), the
Purchaser will accept for payment, and will pay for, up to 27,000,000 Shares
validly tendered prior to the Expiration Date (subject to any pro rata
adjustment in accordance with the terms of the Offer in the event more than
27,000,000 Shares are validly tendered in the Offer) and not properly
withdrawn. The Purchaser expressly reserves the right, in its sole discretion,
to delay acceptance for payment of, or payment for, Shares in order to comply
in whole or in part with any applicable law. Any such delays will be effected
in compliance with Rule 14e-1(c) under the Exchange Act, relating to a
bidder's obligation to pay the consideration offered or return the securities
deposited by or on behalf of holders of securities promptly after the
termination or withdrawal of such bidder's offer.
 
                                       4
<PAGE>
 
  In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
the certificates evidencing such Shares (the "Share Certificates") or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depositary's account at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures set forth in
"Section 3. Procedures for Accepting the Offer and Tendering Shares," (ii) the
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, with any required signature guarantees, or an Agent's Message (as
hereinafter defined) in connection with a book-entry transfer, and (iii) any
other documents required under the Letter of Transmittal. The per Share
consideration paid to any holder of Shares pursuant to the Offer will be the
highest per Share consideration paid to any other holder of such Shares
pursuant to the Offer.
 
  For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered to the Purchaser
(subject to any pro rata adjustment in accordance with the terms of the Offer
in the event more than 27,000,000 Shares are validly tendered in the Offer)
and not properly withdrawn as, if and when the Purchaser gives oral or written
notice to the Depositary of the Purchaser's acceptance for payment of such
Shares pursuant to the Offer. Upon the terms and subject to the conditions of
the Offer, payment for Shares accepted for payment pursuant to the Offer will
be made by deposit of the purchase price therefor with the Depositary, which
will act as agent for tendering stockholders for the purpose of receiving
payments from the Purchaser and transmitting such payments to tendering
stockholders whose Shares have been accepted for payment. Under no
circumstances will interest on the purchase price for Shares be paid,
regardless of any delay in making such payment.
 
  If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, or if Share Certificates are
submitted evidencing more Shares than are tendered, Share Certificates
evidencing unpurchased Shares will be returned, without expense to the
tendering stockholder (or, in the case of Shares tendered by book-entry
transfer into the Depositary's account at the Book-Entry Transfer Facility
pursuant to the procedure set forth in "Section 3. Procedures for Accepting
and Tendering Shares," such Shares will be credited to an account maintained
at the Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.
 
  The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to one or more of its affiliates, the right to purchase
all or any portion of the Shares tendered pursuant to the Offer, but any such
transfer or assignment will not relieve the Purchaser of its obligations under
the Offer and will in no way prejudice the rights of tendering stockholders to
receive payment for Shares validly tendered and accepted for payment pursuant
to the Offer.
 
  3. Procedures for Accepting the Offer and Tendering Shares. In order for a
holder of Shares validly to tender Shares pursuant to the Offer either (a) the
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, together with any required signature guarantees or, in the case of a
book-entry transfer, an Agent's Message, and any other documents required by
the Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase and either the
Share Certificates evidencing tendered Shares must be received by the
Depositary at such address or such Shares must be tendered pursuant to the
procedure for book-entry transfer described below and a Book-Entry
Confirmation must be received by the Depositary, in each case prior to the
Expiration Date, or (b) the tendering stockholder must comply with the
guaranteed delivery procedures described below.
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
                                       5
<PAGE>
 
  Book-Entry Transfer. The Depositary will establish an account with respect
to the Shares at the Book-Entry Transfer Facility for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the Book-Entry Transfer
Facility may make a book-entry delivery of Shares by causing the Book-Entry
Transfer Facility to transfer such Shares into the Depositary's account at the
Book-Entry Transfer Facility in accordance with the Book-Entry Transfer
Facility's procedures for such transfer. Although delivery of Shares may be
effected through book-entry transfer at the Book-Entry Transfer Facility, the
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, together with any required signature guarantees, or an Agent's
Message, and any other required documents, must, in any case, be received by
the Depositary at one of its addresses set forth on the back cover of this
Offer to Purchase prior to the Expiration Date, or the tendering stockholder
must comply with the guaranteed delivery procedure described below. DELIVERY
OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY
TO THE DEPOSITARY.
 
  The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility
has received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against such participant.
 
  Signature Guarantees. Signatures on all Letters of Transmittal must be
guaranteed by a firm which is a financial institution (including most
commercial banks, savings and loan associations and brokerage houses) that is
a participant in the Securities Transfer Agents Medallion Program, the New
York Stock Exchange Medallion Signature Guarantee Program or the Stock
Exchange Medallion Program (each, an "Eligible Institution"), except in cases
where Shares are tendered (i) by a registered holder of Shares who has not
completed either the box entitled "Special Payment Instructions" or the box
entitled "Special Delivery Instructions" on the Letter of Transmittal or (ii)
for the account of an Eligible Institution. If a Share Certificate is
registered in the name of a person other than the signer of the Letter of
Transmittal, or if payment is to be made, or a Share Certificate not accepted
for payment or not tendered is to be returned, to a person other than the
registered holder(s), then the tendered Share Certificate must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name(s) of the registered holder(s) appear on the Share Certificate, with the
signature(s) on such Share Certificate or stock powers guaranteed by an
Eligible Institution. See Instructions 1 and 5 of the Letter of Transmittal.
 
  Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates evidencing such Shares are
not immediately available or such stockholder cannot deliver the Share
Certificates and all other required documents to the Depositary prior to the
Expiration Date, or such stockholder cannot complete the procedure for
delivery by book-entry transfer on a timely basis, such Shares may
nevertheless be tendered, provided that all the following conditions are
satisfied:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form made available by the Purchaser, is
  received prior to the Expiration Date by the Depositary as provided below;
  and
 
    (iii) the Share Certificates (or a Book-Entry Confirmation) evidencing
  all tendered Shares, in proper form for transfer, in each case together
  with the Letter of Transmittal (or a facsimile thereof), properly completed
  and duly executed, with any required signature guarantees, or, in the case
  of a book-entry transfer, an Agent's Message, and any other documents
  required by the Letter of Transmittal are received by the Depositary within
  three NYSE trading days after the date of execution of such Notice of
  Guaranteed Delivery. A "NYSE trading day" is any day on which securities
  are traded on the NYSE.
 
  The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by telegram or facsimile transmission to the Depositary and must
include a guarantee by an Eligible Institution in the form set forth in the
form of Notice of Guaranteed Delivery made available by the Purchaser.
 
 
                                       6
<PAGE>
 
  In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of the
Share Certificates evidencing such Shares, or a Book-Entry Confirmation of the
delivery of such Shares, and the Letter of Transmittal (or a facsimile
thereof), properly completed and duly executed or, in the case of a book-entry
transfer, an Agent's Message, with any required signature guarantees, and any
other documents required by the Letter of Transmittal. Accordingly, tendering
stockholders may be paid at different times depending upon when Share
Certificates, Book-Entry Confirmations and such other documents are actually
received by the Depositary. Under no circumstances will interest be paid by
the Purchaser on the purchase price of the Shares to any tendering
stockholders, regardless of any extension of the Offer or any delay in making
such payment.
 
  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tender of Shares will be determined by the Purchaser in its sole discretion,
which determination shall be final and binding on all parties. The Purchaser
reserves the absolute right to reject any and all tenders determined by it not
to be in proper form or the acceptance for payment of which may, in the
opinion of its counsel, be unlawful. The Purchaser also reserves the absolute
right, subject to the terms of the Merger Agreement, to waive any condition of
the Offer or any defect or irregularity in the tender of any Shares of any
particular stockholder, whether or not similar defects or irregularities are
waived in the case of other stockholders. No tender of Shares will be deemed
to have been validly made until all defects and irregularities have been cured
or waived. None of the Purchaser, the Parent, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty
to give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification. The Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter
of Transmittal and the instructions thereto) will be final and binding.
 
  Other Requirements. By executing the Letter of Transmittal as set forth
above (including through delivery of an Agent's Message), a tendering
stockholder irrevocably appoints designees of the Purchaser as such
stockholder's proxies, each with full power of substitution, in the manner set
forth in the Letter of Transmittal, to the full extent of such stockholder's
rights with respect to the Shares tendered by such stockholder and accepted
for payment by the Purchaser (and with respect to any and all other Shares or
other securities issued or issuable in respect of such Shares on or after the
Expiration Date). All such proxies shall be considered coupled with an
interest in the tendered Shares. Such appointment will be effective when, and
only to the extent that, the Purchaser accepts such Shares for payment. Upon
such acceptance for payment, all prior proxies given by such stockholder with
respect to such Shares (and such other Shares and securities) will be revoked
without further action, and no subsequent proxies may be given nor any
subsequent written consent executed by such stockholder (and, if given or
executed, will not be deemed to be effective) with respect thereto. The
designees of the Purchaser will, with respect to the Shares for which the
appointment is effective, be empowered to exercise all voting and other rights
of such stockholder as they in their sole discretion may deem proper at any
annual or special meeting of the Company's stockholders or any adjournment or
postponement thereof, by written consent in lieu of any such meeting or
otherwise. The Purchaser reserves the right to require that, in order for
Shares to be deemed validly tendered, immediately upon the Purchaser's payment
for such Shares, the Purchaser must be able to exercise full voting rights
with respect to such Shares.
 
  The acceptance for payment by the Purchaser of Shares pursuant to any of the
procedures described above will constitute a binding agreement between the
tendering stockholder and the Purchaser upon the terms and subject to the
conditions of the Offer.
 
  UNDER THE "BACKUP WITHHOLDING" PROVISIONS OF U.S. FEDERAL INCOME TAX LAW,
THE DEPOSITARY MAY BE REQUIRED TO WITHHOLD 31% OF THE AMOUNT OF ANY PAYMENTS
OF CASH PURSUANT TO THE OFFER. IN ORDER TO PREVENT BACKUP FEDERAL INCOME TAX
WITHHOLDING WITH RESPECT TO PAYMENT TO CERTAIN STOCKHOLDERS OF THE PURCHASE
PRICE OF SHARES PURCHASED PURSUANT TO THE OFFER, EACH SUCH STOCKHOLDER MUST
PROVIDE THE DEPOSITARY WITH SUCH STOCKHOLDER'S CORRECT TAXPAYER IDENTIFICATION
NUMBER AND CERTIFY THAT SUCH STOCKHOLDER IS NOT SUBJECT TO BACKUP WITHHOLDING
BY COMPLETING THE SUBSTITUTE FORM W-9 IN THE LETTER OF TRANSMITTAL. CERTAIN
STOCKHOLDERS (INCLUDING, AMONG OTHERS, ALL CORPORATIONS AND CERTAIN FOREIGN
 
                                       7
<PAGE>
 
INDIVIDUALS AND ENTITIES) ARE NOT SUBJECT TO BACKUP WITHHOLDING. IF A
STOCKHOLDER DOES NOT PROVIDE ITS CORRECT TIN OR FAILS TO PROVIDE THE
CERTIFICATIONS DESCRIBED ABOVE, THE INTERNAL REVENUE SERVICE MAY IMPOSE A
PENALTY ON THE STOCKHOLDER AND PAYMENT OF CASH TO THE STOCKHOLDER PURSUANT TO
THE OFFER MAY BE SUBJECT TO BACKUP WITHHOLDING. ALL STOCKHOLDERS SURRENDERING
SHARES PURSUANT TO THE OFFER SHOULD COMPLETE AND SIGN THE SUBSTITUTE FORM W-9
INCLUDED IN THE LETTER OF TRANSMITTAL TO PROVIDE THE INFORMATION NECESSARY TO
AVOID BACKUP WITHHOLDING (UNLESS AN APPLICABLE EXEMPTION EXISTS AND IS PROVED
IN A MANNER SATISFACTORY TO THE DEPOSITARY). NON-CORPORATE FOREIGN
STOCKHOLDERS SHOULD COMPLETE AND SIGN A FORM W-8, CERTIFICATE OF FOREIGN
STATUS (A COPY OF WHICH MAY BE OBTAINED FROM THE DEPOSITARY), IN ORDER TO
AVOID BACKUP WITHHOLDING. SEE INSTRUCTION 10 OF THE LETTER OF TRANSMITTAL.
 
  4. Withdrawal Rights. Tenders of Shares made pursuant to the Offer are
irrevocable except that such Shares may be withdrawn at any time prior to the
Expiration Date and, unless theretofore accepted for payment by the Purchaser
pursuant to the Offer, may also be withdrawn at any time after May 11, 1998.
If the Purchaser extends the Offer, is delayed in its acceptance for payment
of Shares or is unable to accept Shares for payment pursuant to the Offer for
any reason, then, without prejudice to the Purchaser's rights under the Offer,
the Depositary may, nevertheless, on behalf of the Purchaser, retain tendered
Shares, and such Shares may not be withdrawn except to the extent that
tendering stockholders are entitled to withdrawal rights as described in this
"Section 4. Withdrawal Rights."
 
  For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover page of this Offer to
Purchase. Any such notice of withdrawal must specify the name of the person
who tendered the Shares to be withdrawn, the number of Shares to be withdrawn
and the name of the registered holder of such Shares, if different from that
of the person who tendered such Shares. If Share Certificates evidencing
Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, then, prior to the physical release of such Share Certificates,
the serial numbers shown on such Share Certificates must be submitted to the
Depositary and the signature(s) on the notice of withdrawal must be guaranteed
by an Eligible Institution, unless such Shares have been tendered for the
account of an Eligible Institution. If Shares have been tendered pursuant to
the procedure for book-entry transfer as set forth in "Section 3. Procedures
for Accepting the Offer and Tendering Shares," the notice of withdrawal must
specify the name and number of the account at the Book-Entry Transfer Facility
to be credited with the withdrawn Shares.
 
  All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding. None of the
Purchaser, the Parent, the Dealer Manager, the Depositary, the Information
Agent or any other person will be under any duty to give notification of any
defects or irregularities in any notice of withdrawal or incur any liability
for failure to give any such notification.
 
  Any Shares properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the Offer. However, withdrawn Shares may be
re-tendered at any time prior to the Expiration Date by following one of the
procedures described in "Section 3. Procedures for Accepting the Offer and
Tendering Shares."
 
  5. Certain Federal Income Tax Consequences. The summary of U.S. federal
income tax consequences set forth below is for general information only and is
based on the Purchaser's understanding of the law as currently in effect. It
is assumed for purposes of this discussion that the Shares are held and will
continue to be held as "capital assets" within the meaning of Section 1221 of
the Internal Revenue Code of 1986, as amended (the "Code"). The tax
consequences to each stockholder will depend in part upon such stockholder's
particular situation. Special tax consequences not described herein may be
applicable to particular classes of taxpayers, such as financial institutions,
insurance companies, tax-exempt organizations, broker-dealers, persons who are
not citizens or residents of the United States and stockholders who acquired
their Shares through the exercise of an employee stock option or otherwise as
compensation. ALL STOCKHOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS AS
TO THE PARTICULAR TAX CONSEQUENCES OF THE OFFER AND THE MERGER, INCLUDING THE
APPLICABILITY AND EFFECT OF THE ALTERNATIVE MINIMUM

TAX AND ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS AND OF CHANGES
IN SUCH TAX LAWS.
 
  Tax Consequences of the Offer and the Merger Generally. The Offer and the
Merger are intended to qualify as a reorganization within the meaning of
Section 368(a) of the Code. If they are so treated, for U.S. federal income
tax purposes (i) no gain or loss will be recognized by the Parent, the
Purchaser or the Company pursuant to the Offer or the Merger, (ii) a
stockholder of the Company who exchanges all of such stockholder's Shares
solely for cash in the Offer (or upon the exercise of appraisal rights in
connection with the Merger) will recognize gain or loss in an amount equal to
the difference between the cash received and such stockholder's adjusted tax
basis in the Shares surrendered, (iii) a stockholder of the Company who does
not exchange any Shares pursuant to the Offer and who receives solely Parent
Common Stock in exchange for Shares in the Merger will not recognize any gain
or loss, and (iv) a stockholder of the Company who receives a combination of
cash and Parent Common Stock in the Offer and the Merger or in the Merger only
will not recognize loss but will recognize gain, if any, on the Shares so
exchanged to the extent of any cash received. It is a condition to the
respective obligations of each of the Company and the Purchaser that such
party receive an opinion from its tax counsel to the effect that the Merger
qualifies as a reorganization.
 
  Exchange of Shares Solely for Cash. In general, a stockholder of the Company
who exchanges all of such stockholder's Shares for cash in the Offer (or upon
the exercise of appraisal rights in connection with the Merger) will recognize
capital gain or loss equal to the difference between the amount of cash
received and such stockholder's adjusted tax basis in the Shares surrendered.
The gain or loss will be long-term capital gain or loss if, as of the date of
the exchange, the stockholder has held such Shares for more than one year.
 
  Exchange of Shares Solely for Parent Common Stock. A stockholder of the
Company who does not exchange any Shares pursuant to the Offer and who
receives solely Parent Common Stock in exchange for Shares in the Merger will
not recognize any gain or loss upon such exchange. Such stockholder may
recognize gain or loss, however, to the extent cash is received in lieu of a
fractional share of Parent Common Stock, as discussed below. The aggregate
adjusted tax basis of the Shares of Parent Common Stock received in such
exchange will be equal to the aggregate adjusted tax basis of the Shares
surrendered therefor, and the holding period of Parent Common Stock will
include the holding period of the Shares surrendered therefor.
 
  Exchange of Shares for Parent Common Stock and Cash. A stockholder of the
Company who receives a combination of cash and shares of Parent Common Stock
in the Offer and the Merger or in the Merger only will not recognize loss but
will recognize gain, if any, on the Shares so exchanged to the extent of any
cash received. Any such recognized gain will be treated as capital gain unless
the receipt of the cash has the effect of the distribution of a dividend for
U.S. federal income tax purposes, in which case such gain will be treated as
ordinary dividend income to the extent of such stockholder's ratable share of
the Company's accumulated earnings and profits. Any capital gain will be long-
term capital gain if, as of the date of the exchange, the stockholder has held
such Shares for more than one year.
 
  The aggregate adjusted tax basis of the shares of Parent Common Stock
received in such exchanges will be equal to the aggregate tax basis of the
Shares surrendered therefor, decreased by the cash received and increased by
the amount of gain recognized, if any. The holding period of Parent Common
Stock will include the holding period of the Shares surrendered therefor.
 
  Cash Received in Lieu of a Fractional Interest of Parent Common Stock. Cash
received in lieu of a fractional share of Parent Common Stock will be treated
as received in redemption of such fractional interest and gain or loss will be
recognized, measured by the difference between the amount of cash received and
the portion of the basis of the Shares allocable to such fractional interest.
Such gain or loss will be long-term capital gain or loss if, as of the date of
the exchange, the holding period for such Shares was greater than one year.

  The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers. Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on
net capital gain (generally, the excess of net long-term capital gain over net
short-term capital loss). Noncorporate taxpayers are now generally taxed at a
maximum rate of 20% on net capital gain attributable to the sale of property
held for more than eighteen months, and a maximum rate of 28% on net capital
gain attributable to the sale of property held for more than one year but not
more than eighteen months. The 1997 Act did not affect the treatment of short-
term capital gain or loss (generally, gain or loss attributable to capital
assets held for one year or less) and did not affect the taxation of capital
gains in the hands of corporate taxpayers.
 
  A stockholder whose Shares are purchased in the Offer may be subject to 31%
backup withholding unless certain information is provided to the Parent and
the Purchaser or an exemption applies. "Section 3. Procedures for Accepting
the Offer and Tendering Shares."
 
  6. Price Range of Shares; Dividends. The Shares are listed and principally
traded on the NYSE under the symbol AMX. The following table sets forth, for
the quarters indicated, the high and low sales prices per Share on the NYSE.
The Company has not paid cash dividends on Shares in the past and has publicly
disclosed that it does not anticipate doing so in the foreseeable future. In
addition, the Merger Agreement prohibits the payment of dividends by the
Company. See "Section 12. Dividends and Distributions."

  General. The Company is a Delaware corporation with its principal executive
offices located at 3424 Peachtree Road, N.E., Suite 2100, Atlanta, Georgia
30326. The Company is an integrated producer of aluminum products, operating
in a single segment: aluminum processing. Using alumina purchased primarily
from an affiliate of the Parent, the Company produces primary aluminum
employing an electrolytic process at five reduction plants in the United
States and Canada. Primary products are sold externally or further processed
by the Company into a broad range of semi-fabricated and fabricated products.
The Company's products are sold to a wide variety of markets, including
transportation, distributors, building and construction, consumer durables,
and packaging. The Company operates over 70 plants and other manufacturing and
distribution facilities in 22 states, Canada, Western Europe, Mexico,
Australia, the People's Republic of China and Poland.
 
  Relationship with the Company. The Company does not mine bauxite or refine
alumina. Alcoa of Australia Limited, a subsidiary of the Parent, has been the
Company's principal supplier of alumina for over 20 years and currently
provides substantially all of the alumina for the Company's reduction
operations under a long-term contract which, with renewal options, expires in
increments between 2007 and 2018. Pricing under the contract is determined in
part on a cost basis and in part on a market basis, providing the Company with
protection against spot market price extremes during periods of tight supply.
In fiscal years 1997, 1996 and 1995, the Company made aggregate payments under
such contract of $257.7 million, $255.4 million and $182.1 million,
respectively.

  8. Certain Information Concerning the Parent and the Purchaser.
 
  General. The Parent is a corporation organized under the laws of
Pennsylvania. The principal offices of the Parent and the Purchaser are
located at 425 Sixth Avenue, Pittsburgh, Pennsylvania 15219. The Parent is the
world's largest aluminum company and the world's largest alumina producer,
with over 180 operating locations in 28 countries.
 
  The Purchaser is a newly incorporated Delaware corporation organized in
connection with the Offer and the Merger and has not carried on any activities
other than in connection with the Offer and the Merger. The Purchaser is a

that the Purchaser purchases Shares pursuant to the Offer, it is not
anticipated that the Purchaser will have any significant assets or liabilities

withholding of proxies. Except as set forth in this Offer to Purchase, since
January 1, 1995, neither the Purchaser nor the Parent nor, to the best
knowledge of the Purchaser and the Parent, any of the persons listed on
Schedule I hereto, has had any business relationship or transaction with the
Company or any of its executive officers, directors or affiliates that is
required to be reported under the rules and regulations of the Commission
applicable to the Offer. Except as set forth in this Offer to Purchase, since
January 1, 1995, there have been no contracts, negotiations or transactions
between any of the Purchaser, the Parent, or any of their respective
subsidiaries or, to the best knowledge of the Purchaser and the Parent, any of
the persons listed in Schedule I to this Offer to Purchase, on the one hand,
and the Company or its affiliates, on the other hand, concerning a merger,
consolidation or acquisition, tender offer or other acquisition of securities,
an election of directors or a sale or other transfer of a material amount of
assets.

  Parent Available Information. The Parent is subject to the informational
filing requirements of the Exchange Act and, in accordance therewith, is
required to file periodic reports, proxy statements and other information with
the Commission relating to its business, financial condition and other
matters. Information as of particular dates concerning the Parent's directors
and officers, their remuneration, stock options granted to them, the principal
holders of the Parent's securities and any material interest of such persons
in transactions with the Parent is required to be disclosed in proxy
statements distributed to the Parent's stockholders and filed with the
Commission. Such reports, proxy statements and other information should be
available for inspection at the public reference facilities maintained by the
Commission at Judiciary Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549,
and also should be available for inspection at the Commission's regional
offices located at Seven World Trade Center, Suite 1300, New York, New York
10048 and the Citicorp Center, 500 West Madison Street, Suite 1400, Chicago,
Illinois 60661. Copies of such materials may also be obtained by mail, upon

Commission also maintains a World Wide Web site on the Internet at
http://www.sec.gov that contains reports, proxy statements and other
information regarding registrants that file electronically with the
Commission.
 
  9. Financing of the Offer and the Merger. The total amount of funds required
by the Purchaser to consummate the Offer and the Merger and to pay related
fees and expenses is estimated to be approximately $1.4 billion. The Purchaser
will obtain all of such funds from the Parent. The Parent presently intends to
utilize available cash and the proceeds from the public sale of debt
securities pursuant to its effective shelf registration statement and the
private placement of hybrid equity securities. The Parent expects the debt
securities to bear interest at prevailing market rates for such instruments at
the time of issuance and to have maturities of up to 30 years.
 
  10. Background of the Offer; Contacts with the Company; the Merger
Agreement.
 
  In February 1996, Mr. Paul H. O'Neill, Chairman and Chief Executive Officer
of the Parent, called Mr. Allen Born, Chairman and Chief Executive Officer of
the Company, to offer the Parent's support and assistance in light of the
publicly announced unsolicited acquisition proposal made by Kaiser Aluminum
Corporation. Mr. Born
 
                                      14
<PAGE>
 
told Mr. O'Neill that he appreciated the Parent's support and would let the
Parent know if assistance was necessary or appropriate.
 
  During September 1996, Mr. O'Neill and Mr. Born had discussions concerning
the acquisition of the Company by the Parent. On October 6, 1996, Mr. O'Neill
proposed a merger transaction in which the Company's stockholders would
receive .66 of a share of Parent Common Stock which at that time represented a
per Share value of $39.88. Mr. Born informed Mr. O'Neill that the Company
would not consider the Parent's proposal.
 
  On December 9, 1996, Mr. O'Neill sent the following letter to Mr. Born:
 
                                          December 9, 1996
 
  Mr. Allen Born
  Chairman and C.E.O.
  Alumax Inc.
  5655 Peachtree Parkway
  Norcross, GA 30092-2812
 
  Dear Al:
 
    I am writing to you in an effort to rekindle our discussions of a
  possible combination of Alumax and Alcoa. As you know, I believe that
  this combination is so attractive that we should exhaust every
  possibility to see whether it can be accomplished. As I have reflected
  on our prior discussions, I believe market movements over the last
  thirty days make a share-for-share combination even more compelling
  today than it was last month. For these reasons, I would like once
  again to outline our proposed transaction and its rationale for what I
  hope will be favorable consideration by you and your Board of
  Directors.
 
    As we have discussed and, I believe agreed upon, the market has
  established a trading range for the shares of our two companies at
  about .53 Alumax share to 1 Alcoa share. We believe this ratio
  furnishes a logical basis upon which to develop an appropriate exchange
  ratio for the combination of the two companies. In light of this
  historical ratio, our Board of Directors authorized me to pursue a
  combination through a share exchange in which each Alumax share would
  be exchanged for .66 of an Alcoa share. Based on the closing prices of
  Alumax and Alcoa shares last Friday, this represented $41.50 of market
  value for each Alumax share, or a premium of 32%. In addition, the
  exchange ratio of .66 represents a 26% premium to the historical ratio
  of .53.
 
    I would like to point out two special features of the proposed
  combination. First, your shareholders will receive Alcoa shares tax
  free and will be able to defer recognizing gain on their Alumax
  investment until they wish to sell the Alcoa shares they receive.
  Second, since they will receive Alcoa common stock, your shareholders
  will have the opportunity to participate in the upside potential of our
  combined companies. Given the substantial overlap of our very large
  institutional shareholders, I am confident that they will
  enthusiastically support our combination on the basis we are proposing.
 
    I also want to emphasize the importance of maintaining stability
  among employees during a transitional period. It would be our desire to
  have your employees harmoniously integrated into the Alcoa family. We
  have significant experience and have achieved excellent success
  integrating acquired companies into our group, and we have done so on a
  basis which new employees have found to be an attractive and secure
  opportunity. We would expect to do the same for Alumax employees.
 
    We hope that you and your Board of Directors will view this proposal
  as the Alcoa Board of Directors and I do--a unique opportunity for
  Alumax shareholders to realize full value for their shares
 
                                      15
<PAGE>
 
  while maintaining an enhanced investment in a stronger combined company
  with superior growth potential. Please let me know if there is anything
  I can do to help you with your deliberations.
 
                                          Sincerely,
 
                                          /s/
                                          Paul H. O'Neill
 
  cc: Members of the Board of Directors
 
  Following receipt of the letter, the Board of Directors of the Company met
and determined that the proposal outlined in Mr. O'Neill's December 9, 1996
letter was inadequate. Thereafter, Mr. Born sent the following letter to the
Parent:
 
                                          PERSONAL AND CONFIDENTIAL
 
                                          December 16, 1996
 
  Mr. Paul H. O'Neill
  Chairman of the Board and
  Chief Executive Officer
  Aluminum Company of America
  425 Sixth Avenue
  Alcoa Building
  Pittsburgh, Pennsylvania 15219-1850
 
  Dear Paul:
 
    The Alumax Board of Directors has unanimously determined that it is
  not in the best interests of Alumax or our shareholders to pursue a
  business combination at this time and that the financial terms
  suggested by your proposal are wholly inadequate. None of the Alumax
  directors is willing to permit Alumax to be sold for an inadequate
  price at an inopportune time. The Board has full confidence that our
  strategic plan will result in significant value to our shareholders and
  believes that the current aluminum price has resulted in an
  undervaluation of Alumax relative to other aluminum companies.
 
    I trust that with this communication we can continue as before to be
  friends and vigorous competitors.
 
                                          Very truly yours,
 
                                          /s/
                                          Allen Born
 
  cc: Members of the Alumax Board of Directors
 
  In early January 1998, in a telephone conversation with Mr. Born, Mr.
O'Neill briefly mentioned their prior discussions, reaffirmed the Parent's
interest in a business combination with the Company and suggested they meet to
discuss the Parent's interest. Mr. Born told Mr. O'Neill that the Company's
position with respect to those discussions had not changed since December
1996. Nonetheless, on January 14, 1998, Mr. Born and Mr. O'Neill met, and Mr.
O'Neill discussed with Mr. Born the possibility of merging their two companies
in a transaction in which the Company's stockholders would receive .66 of a
share of Parent Common Stock. At that time, .66 of a share of Parent Common
Stock represented a per Share value of $43.68. Mr. Born and Mr. O'Neill could
not reach agreement at that value.
 
                                      16
<PAGE>
 
  On Thursday, January 29, 1998, Mr. O'Neill telephoned Mr. Born and proposed
an acquisition transaction in which the Company's stockholders would receive
 .66 of a share of Parent Common Stock for each outstanding Share. Mr. O'Neill
suggested that the two companies and their advisors proceed with the
mechanical steps required to complete a transaction. Mr. Born requested that
Mr. O'Neill memorialize the Parent's proposal in a letter which he could share
with his Board of Directors. Later that day, Mr. Born called Mr. O'Neill and
requested that the Parent's .66 share exchange proposal include collar
protection for the Company's stockholders. The following day, Mr. O'Neill
called Mr. Born to discuss Mr. Born's request and suggested that the simplest
method for dealing with Mr. Born's concern was to offer the Company's
stockholders $50 per Share in cash. Mr. Born arranged to receive the letter
containing the $50 cash proposal by facsimile transmission at his home early
Sunday morning.
 
  On February 1, 1998, the following letter was faxed to Mr. Born:
 
                                          February 1, 1998
 
  Mr. Allen Born

  Alumax Inc.

  Suite 2100
  Atlanta, GA 30326
  Via Fax: x-xxx/xxx-xxxx
 
  Dear Al:
 
    As you requested, I am writing to summarize the economic terms of our
  proposal for a business combination of Alcoa and Alumax, which we have
  discussed recently. I understand this will afford you a definitive
  basis for seeking authorization from your Board of Directors to
  proceed. In the meantime, let me thank you very much for taking the
  time and trouble to meet with me on this subject two weeks ago and
  again to return my telephone call Thursday afternoon in the midst of
  your travels.
 
    As I told you Thursday, I believe the conditions you outlined in our
  meeting on January 14 for pursuing a transaction have now been
  satisfied and we should proceed to sign and announce an agreement as
  quickly as is possible. Accordingly, Alcoa is prepared to begin
  documenting and implementing an acquisition of Alumax by Alcoa in which
  the stockholders of Alumax would receive $50 in cash for each of their
  shares. This purchase price represents a premium of more than 43% over
  Friday's closing price for Alumax common shares. Promptly following
  signature and announcement of the agreement Alcoa would commence a
  tender offer for all outstanding common shares of Alumax. The tender
  offer would be subject to customary conditions, including applicable
  regulatory approvals and receipt of tenders of at least a majority of
  the outstanding shares on a fully diluted basis.
 
    As I mentioned in our conversation Friday morning, we are prepared to
  dispatch our transaction team (including outside advisors) to New York
  promptly in order to accommodate Board meetings as early as Tuesday and
  an announcement before the opening of the market on Wednesday. We
  expect that the acquisition agreement would be customary for a
  transaction of this type and magnitude. We would expect that the
  agreement would contain appropriate and customary fiduciary termination
  and transaction "break-up" arrangements. Overall, we see no obstacle to
  reaching agreement on the form of the agreement promptly, which is, of
  course, a prerequisite for moving ahead with the proposed transaction.
 
    Maintaining stability among Alumax employees during the transitional
  period is a very high priority for us. To that end, we would in general
  expect to provide programs, plans and benefits which
 
                                      17
<PAGE>
 
  in the aggregate should be comparable to what Alumax employees enjoy as
  a group. We would hope to engender a spirit of enthusiastic
  anticipation among your employees for an attractive and secure
  opportunity with Alcoa.
 
    I am confident your Board of Directors will view this proposal as
  Alcoa's Board of Directors and I do--a unique opportunity for Alumax
  stockholders to realize a substantial premium for their shares. As I
  indicated to you on Friday, I would be happy to discuss or clarify any
  aspect of this letter over the weekend, and I will plan to call you at
  10 AM (EST) on Sunday morning February 1. I understand you can be
  reached at x-xxx/xxx-xxxx. I look forward to talking to you.
 
                                          Sincerely,
 
                                          /s/
                                          Paul H. O'Neill
 
  At a meeting attended by each of the Company's directors on February 4, 1998
prior to the regularly scheduled Board meeting to be held the following day,
Mr. Born reviewed the proposal set forth in Mr. O'Neill's letter of February
1, 1998. After presentations from the Company's legal and financial advisors,
the directors discussed various financial, commercial and regulatory aspects
of the proposal among themselves and concluded that Mr. Born should advise Mr.
O'Neill that the Company was not interested in entertaining the Parent's
proposal at the specified price but would be willing to consider a higher
offer. This conclusion was affirmed at the meeting of the Board held on
February 5, 1998, following further discussion and consultation with
representatives of the Company's financial advisor. Later that day, Mr. Born
telephoned Mr. O'Neill and informed him that the Company's Board of Directors
declined to pursue the Parent's proposal but would be prepared to discuss a
business combination at a higher price. In addition, Mr. Born offered to
provide the Parent with non-public evaluation material concerning the Company
if the Parent would sign a confidentiality agreement.
 
  The following week Mr. Born telephoned Mr. O'Neill to determine whether the
Parent would be willing to enter into the confidentiality agreement and
commence an evaluation of the Company. In the meantime, Mr. O'Neill spoke by
telephone with two directors of the Company and expressed the Parent's very
strong interest in pursuing a transaction with the Company and indicated that,
if it would assist the Company's Board with consideration of the Parent's
proposal, the Parent was prepared to permit the Company to shop the Parent's
proposal and to enter into a transaction with another acquiror at a price
higher than the price being offered by the Parent. Mr. O'Neill was informed by
one of the directors that offering Parent Common Stock as consideration might
be viewed as a more attractive alternative by the Company's Board of Directors
than the Parent's cash proposal.
 
  On Thursday, February 19, 1998, Mr. O'Neill and Mr. Richard B. Kelson,
Executive Vice President and Chief Financial Officer of the Parent, met with
Messrs. Born, Harold Brown and Paul W. MacAvoy, two of the Company's
directors, and Thomas G. Johnston, President and Chief Operating Officer of
the Company, to discuss generally the Parent's proposal. They discussed the
merits of a business combination, the value of such a combination to the
Parent and the appropriate level of consideration for such a transaction. The
Parent's representatives emphasized their view that at $50 per Share the
transaction was fully priced and that the Parent remained prepared to permit
the Company to shop the Company and to seek a transaction at a price higher
than $50 per Share. The Parent's representatives also indicated that the
Parent was prepared to offer half cash and half Parent Common Stock as the
consideration for the transaction. The Company's representatives informed the
Parent's representatives that they would reply to the proposal after
consulting with all of the Company's directors the next week.

<PAGE>
 
  On Wednesday, February 25, 1998, Mr. Born telephoned Mr. O'Neill to inform
him that the Board had rejected the Parent's proposal. That same day he also
sent the following letter to Mr. O'Neill:
 
                                          February 25, 1998
 
  Mr. Paul O'Neill
  Chairman and CEO
  Aluminum Company of America
  ALCOA Building
  425 Sixth Avenue
  Pittsburgh, PA 15219-1850
 
  Dear Paul:
 
    As I have previously advised you, I have again reviewed with our
  Board your unsolicited offer of $50 a share in cash or ALCOA stock for
  each share of Alumax stock. We believe this offer is inadequate and
  unacceptable.
 
    Having said that, I reiterate to you our willingness to discuss a
  transaction between our companies at a price significantly higher than
  you proposed.
 
                                          Sincerely,
 
                                          /s/
                                          Allen Born
                                          Chairman and Chief Executive Officer
 
  On Monday, March 2, 1998, Mr. O'Neill spoke by telephone in separate
conversations with two members of the Company's Board and discussed the
Company's rejection of the Parent's proposal. Mr. O'Neill reiterated his
strong belief in the timeliness of a combination, the desirability of the
proposed transaction from the Company's stockholders' point of view and, in
particular, the desirability of offering those stockholders the chance to
exchange a part of their investment into Parent Common Stock. The directors
indicated that they believed the Parent's proposal should be discussed at the
meeting of the directors on Wednesday evening and the regularly scheduled
Board meeting on Thursday of that week and that a brief explanation of the
desirability of the transaction and the opportunity to invest in the Parent
Common Stock might be helpful.
 
   In response to the directors' comments described above, on Wednesday, March
4, 1998, the Parent provided the following list of "talking points" to one of
the directors for use at the Board meeting:
 
    . Merger of Alumax with Alcoa
 
      .  Approximately 1/2 the outstanding Alumax shares
         exchanged for $50 worth of Alcoa stock
 
      .  Remaining shares exchanged for $50 in cash
 
    .  Merger Agreement provides floor against which to seek
       superior economics elsewhere
 
      .  No limit on post-signature shopping of Alumax
 
      .  The Agreement may be terminated with "fiduciary out"
 
      .  No requirement for breakup fee if company sold
         elsewhere for more money
 
    .  Attractive premium
 
      .  $50--35.6% over yesterday's closing price
 
      .  Share portion--Exchange at 39.9% premium to historical
         trading ratio for last 12 months

  During the meeting of directors on the evening of March 4, the Company's
directors concluded that Mr. Born and certain other representatives of the
Company should meet with Mr. O'Neill to discuss and obtain clarification of
the Parent's proposal. Mr. O'Neill was called that evening and a meeting was
scheduled for the following afternoon. Mr. O'Neill was asked to be prepared to
present the Parent's proposal in writing at the meeting. At its regularly
scheduled Board meeting on March 5, the Company's Board again considered the
factors discussed the prior evening. After lengthy discussion, the Board
formally authorized management to pursue the proposal. That afternoon Messrs.
O'Neill, Alain J. P. Belda, President and Chief Operating Officer of the
Parent, and Kelson met with Messrs. Born, Johnston and Brown and presented the
following letter to them:
 
                                          March 5, 1998
 
  The Board of Directors
  Alumax Inc.
  3424 Peachtree Road, NE
  Atlanta, GA 30326
 
  Lady and Gentlemen:
 
    This letter is to formalize the discussions we have been having
  concerning a transaction between Alumax and Alcoa as requested. Alcoa
  is prepared to proceed immediately with a merger transaction in which
  approximately one-half the total number of outstanding Alumax shares
  would be exchanged for $50 worth of Alcoa stock and the remaining
  shares would be exchanged for $50 in cash. The merger agreement would
  contain no limitation on your ability to shop the company and would
  permit
 
                                      20
<PAGE>
 
  termination on fiduciary grounds with no requirement to pay a break-up
  fee if you were able to sell the company to someone else for more
  money. We would expect to structure the transaction in two steps,
  commencing with a cash tender offer and finishing with a merger in
  which the remaining shares are converted into Alcoa stock. We assume
  you would like to negotiate a reasonable collar and market test period
  for the stock portion of the consideration, and we are prepared to do
  that with you. The agreement would provide for a cash out of all
  options. The transaction will be subject only to usual and customary
  conditions.
 
    In our discussions with your Chairman and certain other of your
  members we have discussed a variety of considerations for Alumax
  stockholders which would lead them to conclude that our proposal is one
  they should accept, and, in particular, that the opportunity to convert
  a portion of their investment in Alumax into an investment in a
  combined Alcoa and Alumax is especially attractive. We hope you will
  give special weight and attention to the following factors which
  strongly favor an investment in Alcoa compared with an investment in
  Alumax alone:
 
    .  Attractive premium
 
      .  $50--37.2% over yesterday's closing price
 
      .  Share portion--Exchange at 42.4% premium to one-year historical
         trading ratio

  BY HAND DELIVERY
 
  In the course of the discussions of the proposal set forth in the March 5
letter, the Company's representatives requested that there be a fixed exchange
ratio for the stock portion of the consideration based on the prior day's
closing market price of the Parent Common Stock so that the value of this
portion of the consideration payable in the transaction would fluctuate with
future changes in the market price of the Parent Common Stock. In the course
of the negotiations the Parent representatives agreed to a fixed exchange
ratio at .6975. The parties also agreed in principle that subject to Board
approvals and to negotiation and execution of a satisfactory form of merger
agreement they were prepared to proceed with a transaction. Thursday evening,
the Parent's representatives delivered a draft merger agreement to the
Company's representatives. On Friday, March 6, the Company requested a new
letter revising certain provisions in the letter delivered on Thursday,
including changes to reflect the Exchange Ratio and to provide that all
Company stock options would be "rolled over" into options to acquire Parent
Common Stock--which the Parent delivered that afternoon.
 
  On Friday, March 6, the Parent's Board of Directors met and authorized
management to negotiate the final documentation for the transactions
contemplated by the Merger Agreement. That same day the Company's Board
convened for an informational meeting and the directors agreed that the
Company should proceed to negotiate a definitive agreement incorporating the
proposal set forth in the Parent's March 6th letter. Negotiation of the
definitive acquisition agreement continued throughout Friday, Saturday and
Sunday.
 
  On Saturday, March 7, the Company's Board met and approved in principle the
transaction outlined in the revised letter delivered by the Parent on March 6,
subject to the completion of the negotiation of an acceptable definitive
acquisition agreement.
 
  On Sunday, March 8, the Company's Board of Directors met and approved the
transactions contemplated by the Merger Agreement. The Merger Agreement was
thereafter executed and delivered on March 8, 1998.
 
THE MERGER AGREEMENT
 
  The following is a summary of the Merger Agreement, a copy of which is filed
as an Exhibit to the Tender Offer Statement on Schedule 14D-1 (the "Schedule
14D-1") filed by the Purchaser and the Parent with the Commission in
connection with the Offer. Such summary is qualified in its entirety by
reference to the Merger Agreement.
 
  The Offer. The Merger Agreement provides for the making of the Offer as
provided in this Offer to Purchase.
 
  The Merger. The Merger Agreement provides that, upon the terms and subject
to the conditions thereof and in accordance with the DGCL, the Company shall
merge with and into the Purchaser and the separate corporate existence of the
Company will thereupon cease, and the Purchaser will be the Surviving
Corporation in the Merger. Upon consummation of the Merger, each Share that is
owned by the Parent, the Purchaser, any of their respective subsidiaries, the
Company or any subsidiary of the Company shall automatically be cancelled and
retired and shall cease to exist, and no consideration shall be delivered in
exchange therefor. Each issued and outstanding Share, other than Excluded
Shares (as hereinafter defined) and Dissenting Shares, shall be converted
into, and become exchangeable for the right to receive: (A) 0.6975 of a share
of Parent Common Stock if the Purchaser purchased no fewer than the 50% Share
Number of Shares in the Offer; or (B) that fraction of a
 
                                      22
<PAGE>
 
share of Parent Common Stock equal to the Adjusted Exchange Ratio plus an
amount in cash equal to the Merger Cash Prorate Amount, if the Purchaser
purchased fewer than the 50% Number of Shares in the Offer. The term "Excluded
Shares" means that number of Shares owned by the Parent and its subsidiaries
immediately prior to the Effective Time (excluding Shares held by the Company
and its subsidiaries). The Merger Agreement provides that if, prior to the
Effective Time, the Parent effects a change in the number of shares of Parent
Common Stock or securities convertible or exchangeable into or exercisable
therefor, the Merger Consideration will be equitably adjusted.
 
  Charter Documents; Initial Directors and Officers. The Merger Agreement
provides that, at the Effective Time, the Certificate of Incorporation of the
Purchaser, as in effect immediately prior to the Effective Time, will be the
Certificate of Incorporation of the Surviving Corporation; provided, however,
that Article FIRST of the Certificate of Incorporation of the Surviving
Corporation will be amended in its entirety to read as follows: "FIRST: The
name of the corporation is Alumax Inc." The Merger Agreement also provides
that, at the Effective Time the By-laws of the Purchaser, as in effect
immediately prior to the Effective Time, will be the By-laws of the Surviving
Corporation. Pursuant to the Merger Agreement, the directors of the Purchaser
at the Effective Time will be the directors of the Surviving Corporation, and
the officers of the Purchaser at the Effective Time will be the officers of
the Surviving Corporation, in each case, until their respective successors are
duly elected and qualified or their earlier death, resignation or removal in
accordance with the Certificate of Incorporation and By-laws of the Surviving
Corporation.
 
  Stockholders' Meeting. The Merger Agreement provides that as promptly as
practicable following the date of the Merger Agreement, the Company, acting
through its Board of Directors, will, in accordance with applicable law duly
call, give notice of, convene and hold the Company Special Meeting for the
purposes of considering and taking action upon the approval of the Merger and
the approval and adoption of the Merger Agreement.
 
  Filings. The Merger Agreement provides that the Company will, as promptly as
practicable following the date of the Merger Agreement, prepare and file with
the Commission a preliminary proxy or information statement relating to the
Merger and the Merger Agreement and will cause a definitive proxy or
information statement, including any amendment or supplement thereto (the
"Proxy Statement") to be mailed to its stockholders at the earliest
practicable date after the Registration Statement (as hereinafter defined) is
declared effective by the Commission. In addition, the Merger Agreement
obligates the Company to use its reasonable best efforts to obtain the
necessary approvals of the Merger and the Merger Agreement by its
stockholders. The Company has agreed that unless the Merger Agreement has been
terminated in accordance with its terms it will include in the Proxy Statement
the recommendation of the Board that stockholders of the Company vote in favor
of the approval of the Merger and the approval and adoption of the Merger
Agreement; provided, however, that if the Board of Directors of the Company,
based on the advice of outside legal counsel, determines in good faith that
there is an Acquisition Proposal (as hereinafter defined) which is a Superior
Proposal (as hereinafter defined) and it is necessary for the Board of
Directors of the Company in order to avoid breaching its fiduciary duties to
the Company's stockholders under applicable law, the Board may amend or
withdraw its recommendation.
 
  The Merger Agreement provides that the Parent shall as promptly as
practicable following the date of the Merger Agreement prepare and file with
the Commission a registration statement (the "Registration Statement"), in
which the Proxy Statement shall be included as a prospectus, and shall use its
reasonable best efforts to have the Registration Statement declared effective
by the Commission as promptly as practicable.
 
  Conduct of Business Pending the Merger. Pursuant to the Merger Agreement,
the Company has agreed that, from and after the date of the Merger Agreement
and prior to the Effective Time or the date, if any, on which the Merger
Agreement is earlier terminated pursuant to the terms and conditions thereof,
and except as may be agreed in writing by the other parties to the Merger
Agreement or as may be expressly permitted pursuant to the Merger Agreement,
the Company:
 
    (i) will, and will cause each of its subsidiaries to, conduct its
  operations according to their ordinary and usual course of business in
  substantially the same manner as conducted prior to the date of the Merger
  Agreement;
 
                                      23

    (ii) will use its reasonable best efforts, and cause each of its
  subsidiaries to use its reasonable best efforts, to preserve intact its
  business organization and goodwill, keep available the services of its
  current officers and other key employees and preserve its relationships
  with those persons having business dealings with the Company and its
  subsidiaries;
 
    (iii) will confer at such times as the Parent may reasonably request with
  one or more representatives of the Parent to report material operational
  matters and the general status of ongoing operations;
 
    (iv) will notify the Parent of any emergency or other change in the
  normal course of its or its subsidiaries' respective businesses or in the
  operation of its or its subsidiaries' respective properties and of any
  complaints or hearings (or communications indicating that the same may be
  contemplated) of any governmental entity, if such emergency, change,
  complaint, investigation or hearing would have a Material Adverse Effect
  (as defined in the Merger Agreement) on the Company;
 
    (v) will not, and will not permit any of its subsidiaries that is not
  wholly owned to, authorize or pay any dividends on or make any distribution
  with respect to its outstanding shares of stock;
 
    (vi) will not, and will not permit any of its subsidiaries to, except as
  otherwise provided in the Merger Agreement, establish, enter into or amend
  any employee benefit plan or increase the compensation payable or to become
  payable or the benefits provided to its officers or employees, subject to
  certain exceptions;
 
    (vii) subject to certain exceptions will not, and will not permit any of
  its subsidiaries to, authorize, propose or announce an intention to
  authorize or propose, or enter into an agreement with respect to, any
  merger, consolidation or business combination (other than the Merger), any
  acquisition or disposition of an amount of assets or securities, in each
  case in excess of $1 million, except (x) for the sale of goods and products
  manufactured by the Company and held for sale in the ordinary course and
  (y) certain expenditures not in excess of $150 million in the aggregate;
 
    (viii) will not, and will not permit any of its subsidiaries to, propose
  or adopt any amendments to its certificate of incorporation or by-laws (or
  other similar organizational documents);
 
    (ix) will not, and will not permit any of its subsidiaries to, issue or
  authorize the issuance of, or agree to issue or sell any shares of capital
  stock of any class (whether through the issuance or granting of options,
  warrants, commitments, subscriptions, rights to purchase or otherwise)
  other than certain issuances expressly permitted by the Merger Agreement;
 
    (x) will not, and will not permit any of its subsidiaries to, reclassify,
  combine, split, purchase or redeem any shares of its capital stock or
  purchase or redeem any rights, warrants or options to acquire any such
  shares;
 
    (xi) other than in the ordinary course of business consistent with past
  practice, will not, and will not permit any of its subsidiaries to, (a)
  incur, assume or prepay any indebtedness or any other material liabilities
  or issue any debt securities, or (b) assume, guarantee, endorse or
  otherwise become liable or responsible (whether directly, contingently or
  otherwise) for the obligations of any other person, other than guarantees
  of obligations of wholly owned subsidiaries of the Company in the ordinary
  course of business;
 
    (xii) will not, and will not permit any of its subsidiaries to, (a) sell,
  lease, license, mortgage or otherwise encumber or subject to any lien or
  otherwise dispose of any of its properties or assets (including
  securitizations), other than in the ordinary course of business consistent
  with past practice; (b) modify, amend or terminate any of its material
  contracts or waive, release or assign any material rights (contract or
  other); or (c) permit any insurance policy naming it as a beneficiary or a
  loss payable payee to lapse, be cancelled for reasons within the Company's
  control or expire unless a new policy with substantially identical coverage
  is in effect as of the date of lapse, cancellation or expiration;
 
    (xiii) will not, and will not permit any of its subsidiaries to, (a) make
  any material tax election or settle or compromise any material tax
  liability or (b) change any of the accounting methods used by it unless
  required by GAAP; and
 
    (xiv) will not, and will not permit any of its subsidiaries to, agree, in
  writing or otherwise, to take any of the foregoing actions or knowingly
  take any action which would (y) make any representation or warranty in the
  Merger Agreement untrue or incorrect in any material respect or (z) result
  in any of the conditions to the Offer set forth in "Section 14. Conditions
  to the Offer" or any of the conditions to the Merger set forth in the
  Merger Agreement not being satisfied.
 
                                      24

  Directors. The Merger Agreement provides that, promptly upon the purchase of
and payment for any Shares by the Purchaser or any of its affiliates pursuant
to the Offer, the Parent will be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of
the Company as is equal to the product obtained by multiplying the total
number of directors on such Board (giving effect to the directors designated
by the Parent pursuant to this sentence) by the percentage that the number of
Shares so accepted for payment bears to the total number of Shares then
outstanding. In furtherance thereof, the Merger Agreement provides that the
Company is obligated, upon request of the Purchaser, to increase promptly the
size of its Board of Directors or exercise its best efforts to secure the
resignations of such number of directors, or both, as is necessary to enable
the Parent's designees to be so elected to the Company's Board and will cause
the Parent's designees to be so elected. The Company has agreed that, at such
time, the Company will, if requested by the Parent, cause directors designated
by the Parent to constitute at least the same percentage (rounded up to the
next whole number) as is on the Company's Board of Directors of (i) each
committee of the Company's Board of Directors, (ii) each board of directors
(or similar body) of each Significant Subsidiary (as defined in the Merger
Agreement) of the Company, and (iii) each committee (or similar body) of each
such board. Notwithstanding the foregoing, if Shares are purchased pursuant to
the Offer, the Merger Agreement requires there be at least one member of the
Company's Board of Directors who was a director on the date of the Merger
Agreement and is not an employee of the Company until the Effective Time.
 
  Solicitation by the Company. The Merger Agreement provides that nothing
contained in the Merger Agreement prohibits the Board of Directors of the
Company from furnishing information to, or entering into discussions with, any
Person that makes a bona fide Acquisition Proposal. The term "Acquisition
Proposal" as defined in the Merger Agreement means any tender or exchange
offer involving the capital stock of the Company or any of its subsidiaries,
any proposal or offer to acquire in any manner a substantial equity interest
in, or a substantial portion of the business or assets of, the Company or any
of its subsidiaries, any proposal or offer with respect to any merger,
consolidation, business combination, recapitalization, liquidation,
dissolution or restructuring of or involving the Company or any of its
subsidiaries, or any proposal or offer with respect to any other transaction
similar to any of the foregoing with respect to the Company or any of its
subsidiaries, other than the transactions contemplated by the Merger
Agreement. Additionally, the Merger Agreement provides that nothing contained
in the Merger Agreement prohibits the Company from taking and disclosing to
its stockholders a position contemplated by Rule 14e-2(a) promulgated under
the Exchange Act or from making any disclosure to the Company's stockholders
if the Board of Directors of the Company determines in good faith, after
consultation with outside legal counsel, that it is necessary to do so in
order to avoid breaching its fiduciary duties under applicable law; provided,
however, that neither the Company nor its Board of Directors nor any committee
thereof may withdraw or modify, or propose publicly to withdraw or modify, its
position with respect to the Merger Agreement, the Offer or the Merger, or
approve or recommend, or propose publicly to approve or recommend, an
Acquisition Proposal, except if, and only to the extent that, the Board of
Directors of the Company, based on the advice of outside legal counsel,
determines in good faith that such Acquisition Proposal is a bona fide
Acquisition Proposal made by a third party to acquire, directly or indirectly,
20% or more of the outstanding Shares on a fully diluted basis or all or
substantially all the assets of the Company and its subsidiaries and otherwise
on terms and conditions which the Board of Directors of the Company determines
in good faith, after consultation with and based upon the written opinion of
its financial advisor, to be a superior financial alternative to the
stockholders of the Company than the Offer and the Merger (a "Superior
Proposal") and that such action is necessary for the Board of Directors of the
Company to avoid breaching its fiduciary duties to the Company's stockholders
under applicable law; and provided, further, that the Board is not required to
violate applicable laws.
 
  Directors' and Officers' Indemnification. The Merger Agreement provides that
from and after the Effective Time, the Parent will indemnify and hold harmless
each present and former director and officer of the Company and its
subsidiaries (the "Indemnified Parties"), against any costs or expenses
(including attorneys' fees), judgments, fines, losses, claims, damages or
liabilities incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative,
arising out of or pertaining to matters existing or occurring at or prior to
the Effective Time, to the fullest extent that the Company or such
 
                                      25
<PAGE>
 
subsidiary would have been permitted under applicable law and the Certificate
of Incorporation or By-laws of the Company or such subsidiary in effect on the
date of the Merger Agreement to indemnify such person (and the Parent shall
also advance expenses as incurred to the fullest extent permitted under
applicable law provided the Person to whom expenses are advanced provides an
undertaking to repay such advances if it is ultimately determined that such
Person is not entitled to indemnification).
 
  Employee Stock Options. The Merger Agreement provides that simultaneously
with the Merger, (i) each outstanding option (the "Company Stock Options") to
purchase or acquire a Share under employee incentive or benefit plans,
programs or arrangements and non-employee director plans presently maintained
by the Company (the "Company Option Plans") will be converted into an option
to purchase the number of shares of Parent Common Stock equal to the product
of (x) the Exchange Ratio multiplied by (y) the number of Shares which could
have been issued prior to the Effective Time upon the exercise of such option,
at an exercise price per share (rounded upward to the nearest cent) equal to
the exercise price for each Share subject to such option divided by the
Exchange Ratio, and all references in each such option to the Company will be
deemed to refer to the Parent, where appropriate, provided, however, that with
respect to any option which is an "incentive stock option," within the meaning
of Section 422 of the Code, such adjustments shall, if applicable, be modified
in a manner so that the adjustments are consistent with requirements of
Section 424(a) of the Code, and (ii) the Parent will assume the obligations of
the Company under the Company Option Plans. The Merger Agreement also provides
that the other terms of each such option, and the plans under which they were
issued, will continue to apply in accordance with their terms, including any
provisions providing for acceleration and that at or prior to the Effective
Time, the Parent has agreed to take all corporate action necessary to reserve
for issuance a sufficient number of shares of Parent Common Stock for delivery
upon exercise of Company Stock Options assumed by it in accordance with the
Merger Agreement. The Parent has agreed that, as soon as practicable after the
Effective Time, if necessary, it will file a registration statement on Form S-
8 (or any successor or other appropriate forms), or another appropriate form
with respect to the shares of Parent Common Stock subject to such Company
Stock Options, and will use its best efforts to maintain the effectiveness of
such registration statement (and maintain the current status of the prospectus
or prospectuses contained therein) for so long as the former Company Stock
Options remain outstanding.
 
  Representations and Warranties. The Merger Agreement contains various
customary representations and warranties of the parties thereto including
representations by the Company as to the Company's corporate organization and
qualification, capital stock, corporate authority, filings with the Commission
and other governmental authorities, financial statements, litigation, employee
matters, employment benefit matters, intellectual property, tax matters,
environmental matters, compliance with law, the absence of certain changes or
events, opinion of financial advisor and undisclosed liabilities.
 
  Conditions to Consummation of the Merger. The Merger Agreement provides that
the respective obligations of each party to effect the Merger are subject to
the following conditions: (a) the Merger Agreement and the transactions
contemplated thereby will have been approved and adopted by the affirmative
vote of the holders of a majority of the outstanding Shares; (b) no statute,
rule, regulation, executive order, decree, ruling or injunction will have been
enacted, entered, promulgated or enforced by any Governmental Entity (as
defined in the Merger Agreement) which prohibits the consummation of the
Merger substantially on the terms contemplated in the Merger Agreement or has
the effect of making the acquisition of Shares by the Parent or the Purchaser
or any affiliate of either of them illegal; (c) the Parent or the Purchaser or
any affiliate of either of them have purchased Shares pursuant to the Offer,
except that this condition will not apply if the Parent, the Purchaser or such
affiliate has failed to purchase Shares pursuant to the Offer in breach of
their obligations under the Merger Agreement; (d) the applicable waiting
period under the HSR Act shall have expired or been terminated; (e) the shares
of Parent Common Stock to be issued in the Merger will have been approved for
listing on the NYSE, subject to official notice of issuance and (f) the
Registration Statement shall have become effective in accordance with the
provisions of the Securities Act of 1933, as amended. In addition, the Merger
Agreement provides (i) that the obligation of the Parent and the Purchaser to
effect the Merger shall be subject to the receipt by the Parent of an opinion
of Skadden, Arps, Slate, Meagher & Flom LLP, tax counsel to the Parent, dated
as of the
 
                                      26
<PAGE>
 
Effective Time, to the effect that the Merger will qualify as a reorganization
within the meaning of Section 368(a) of the Code and that (ii) that the
obligation of the Company to effect the Merger shall be subject to the receipt
by the Company of an opinion of Sullivan & Cromwell, tax counsel to the
Company, dated as of the Effective Time, to the effect that the Merger will
qualify as a reorganization within the meaning of Section 368(a) of the Code.
 
  The Merger Agreement also provides that, in the event that the Purchaser
purchases a number of Shares in the Offer which is less than the 50% Share
Number, the respective obligations of the Parent and the Purchaser and the
Company to effect the Merger shall be subject to the fulfillment at or prior
to the Effective Time of the following conditions, unless waived in writing by
the party to which the condition applies or unless the Company Stockholder
Approval is obtained prior thereto, in which event such conditions will
thereupon be deemed fulfilled: (i) that the representations and warranties of
the other party or parties, as the case may be, set forth in the Merger
Agreement will be true and correct, ignoring for this purpose any
qualification as to materiality or Material Adverse Effect, as if such
representations or warranties were made as of the Effective Time, except for
such inaccuracies as, individually or in the aggregate, would not have a
Material Adverse Effect on such party or parties, (ii) that the other party
will have performed and complied in all material respects with all agreements,
obligations and conditions required by the Merger Agreement to be performed
and complied with by it on or prior to the closing date and (iii) that such
party or parties will have furnished a certificate of an officer to evidence
compliance with the conditions set forth in clauses (i) and (ii) of this
sentence.
 
  Termination. The Merger Agreement may be terminated and the Merger and the
other transactions contemplated thereby may be abandoned at any time prior to
the Effective Time, notwithstanding any requisite approval by the stockholders
of the Company: (a) by mutual written consent of the Parent, the Purchaser and
the Company; (b) by either the Parent or the Company if (i) (1) the Offer has
expired without any Shares being purchased pursuant thereto, or (2) the Offer
has not been consummated on or before September 30, 1998 (the "Termination
Date"); provided, however, that such right to terminate the Merger Agreement
is not available to any party whose failure to fulfill any obligation under
the Merger Agreement has been the cause of, or resulted in, the failure of the
Shares to have been purchased pursuant to the Offer; (ii) a statute, rule,
regulation or executive order has been enacted, entered or promulgated
prohibiting the consummation of the Offer or the Merger substantially on the
terms contemplated by the Merger Agreement; or (iii) an order, decree, ruling
or injunction has been entered permanently restraining, enjoining or otherwise
prohibiting the consummation of the Offer or the Merger substantially on the
terms contemplated by the Merger Agreement and such order, decree, ruling or
injunction has become final and non-appealable; provided further that the
Termination Date will be extended by one business day for each business day
which elapses from March 16, 1998, until the date upon which the applicable
filings under the HSR Act are made by the Company with the appropriate
governmental entity; (c) by the Parent, (i) if due to an occurrence or
circumstance, other than as a result of a breach by the Parent or the
Purchaser of its obligations hereunder, resulting in a failure to satisfy any
condition set forth in "Section 14. Conditions to the Merger," hereto, the
Purchaser has (1) failed to commence the Offer within 30 days following the
date of the Merger Agreement, or (2) terminated the Offer without having
accepted any Shares for payment thereunder; or (ii) if either the Parent or
the Purchaser is entitled to terminate the Offer as a result of the occurrence
of any event set forth in paragraph (e) of "Section 14. Conditions to the
Merger" hereto; (d) by the Company, upon approval of its Board of Directors,
if due to an occurrence or circumstance, other than as a result of a breach by
the Company of its obligations under the Merger Agreement, that would result
in a failure to satisfy any of the conditions set forth in "Section 14.
Conditions to the Merger," hereto, the Purchaser terminates the Offer without
having accepted any Shares for payment thereunder; (e) by the Company, if the
Company receives a Superior Proposal and the Board of Directors of the
Company, based on the advice of outside legal counsel, determines in good
faith that such action is necessary for the Board of Directors to avoid
breaching its fiduciary duties to the Company's stockholders under applicable
law; or (f) by the Parent or the Company, if after the Company convenes and
holds the Company Special Meeting and certifies the vote with respect to the
Merger, the Company's stockholders have voted against granting the Company
Stockholder Approval.
 
  Fees and Expenses. The Merger Agreement provides that except as expressly
contemplated by the Merger Agreement, all costs and expenses incurred in
connection therewith and the transactions contemplated thereby shall be paid
by the party incurring such costs and expenses.
 
                                      27
<PAGE>
 
  Amendment. At any time prior to the Effective Time, the Merger Agreement may
be amended or supplemented in any and all respects, whether before or after
Company Stockholder Approval, by written agreement of the parties thereto, by
action taken by their respective Boards of Directors (which, following the
election of the Parent's designees upon consummation of the Offer, in the case
of the Company, will require the concurrence of a majority of the directors of
the Company then in office who were neither designated by the Parent nor are
employees of the Company), with respect to any of the terms contained in the
Merger Agreement; provided, however that following the Company Stockholder
Approval there shall be no amendment or change to the provisions thereof which
would reduce the amount or change the type of consideration into which each
Share shall be converted upon consummation of the Merger without further
approval by the stockholders of the Company.
 
  11. Purpose of the Offer; Plans for the Company after the Offer and the
Merger.
 
  Purpose of the Offer. The purpose of the Offer is for the Purchaser to
acquire a majority of the outstanding Shares as a first step in acquiring the
entire equity interest in the Company. The purpose of the Merger is for the
Purchaser to acquire all Shares not acquired pursuant to the Offer. Assuming
that all the conditions to the Merger are satisfied, pursuant to the Merger,
the Company will be merged with and into the Purchaser, with the Purchaser
surviving the Merger as a direct, wholly owned subsidiary of the Parent. The
Offer is being made pursuant to the Merger Agreement.
 
  Under the DGCL, the approval of the Company's Board and the affirmative vote
of the holders of a majority of the outstanding Shares are required to approve
and adopt the Merger Agreement and the transactions contemplated thereby,
including the Merger. The Board of Directors of the Company has unanimously
(with one director absent) approved the Merger Agreement and the transactions
contemplated thereby and determined that the terms of the Offer and the Merger
are fair to, and in the best interests of, the Company and its stockholders.
The only remaining required corporate action of the Company is the approval
and adoption of the Merger Agreement and the transactions contemplated thereby
by the affirmative vote of the holders of a majority of the Shares. In the
Merger Agreement, the Company has agreed to duly call, give notice of, convene
and hold a special meeting of its stockholders as promptly as practicable
after the date of the Merger Agreement for the purpose of considering and
taking action on the Merger Agreement and the transactions contemplated
thereby.
 
  The Purchaser has agreed that all Shares owned by it and any of its
affiliates will be voted in favor of the Merger Agreement and the transactions
contemplated thereby.
 
  If the Purchaser purchases Shares pursuant to the Offer, the Merger
Agreement provides that the Parent will be entitled to designate
representatives to serve on the Board of the Company substantially in
proportion to the Purchaser's ownership of Shares following such purchase. See
"Section 10. Background of the Offer; Contacts with the Company; the Merger
Agreement." If the Purchaser purchases a number of Shares greater than or
equal to the 50% Share Number, the Purchaser expects that such representation
would permit the Parent effectively to control the Company's conduct of its
business and operations.
 
  Appraisal Rights. No appraisal rights are available in connection with the
Offer. If a number of Shares less than the 50% Share Number is purchased
pursuant to the Offer, a portion of the Merger Consideration will be paid in
cash as described in "Introduction." In such event, stockholders of the
Company will have certain rights under the DGCL to dissent and demand
appraisal of, and to receive payment in cash of the fair value of, their
Shares. Such rights, if the statutory procedures are complied with, could lead
to a judicial determination of the fair value (excluding any element of value
arising from the accomplishment or expectation of the Merger) required to be
paid in cash to such dissenting holders for their Shares. Any such judicial
determination of the fair value of Shares could be based upon considerations
other than or in addition to the price paid in the Offer and the market value
of the Shares, including asset values and the investment value of the Shares.
The value so determined could be more or less than the purchase price per
Share pursuant to the Offer or the consideration per Share to be paid in the
Merger.
 
 
                                      28
<PAGE>
 
  In addition, several decisions by Delaware courts have held that, in certain
instances, a controlling stockholder of a corporation involved in a merger has
a fiduciary duty to the other stockholders that requires the merger to be fair
to such other stockholders. In determining whether a merger is fair to
minority stockholders, the Delaware courts have considered, among other
things, the type and amount of consideration to be received by the
stockholders and whether there were fair dealings among the parties. The
Delaware Supreme Court has indicated in recent decisions that in most cases
the remedy available in a merger that is found not to be "fair" to minority
stockholders is the right to appraisal described above or a damages remedy
based on essentially the same principles.
 
  The foregoing summary of the rights of dissenting stockholders does not
purport to be a complete statement of the procedures to be followed by
stockholders desiring to exercise their appraisal rights. The preservation and
exercise of appraisal rights are conditioned on strict adherence to the
applicable provisions of the DGCL.
 
  Plans for the Company. It is expected that, initially following the Merger,
the business and operations of the Company will, except as set forth in this
Offer to Purchase, be continued substantially as they are currently being
conducted. The Parent will continue to evaluate the business and operations of
the Company during the pendency of the Offer and after the consummation of the
Offer and the Merger and will take such actions as it deems appropriate under
the circumstances then existing. The Parent intends to seek additional
information about the Company during this period. Thereafter, the Parent
intends to review such information as part of a comprehensive review of the
Company's business, operations, capitalization and management with a view to
optimizing development of the Company's potential in conjunction with the
Parent's businesses.
 
  Except as indicated in this Offer to Purchase, the Parent does not have any
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any Company subsidiary, a sale or transfer of a
material amount of assets of the Company or any Company subsidiary or any
material change in the Company's capitalization or dividend policy or any
other material changes in the Company's corporate structure or business.
 
  12. Dividends and Distributions. The Company has not paid cash dividends to
date and has advised the Parent that it intends to retain future earnings for
use in the business.
 
  The Merger Agreement provides that between the date of the Merger Agreement
and the Effective Time, without the prior written consent of the Parent, the
Company, (a) will not, and will not permit any of its subsidiaries that is not
wholly owned to, authorize or pay any dividends on or make any distribution
with respect to its outstanding shares of stock; (b) will not, and will not
permit any of its subsidiaries to, issue or authorize the issuance of, or
agree to issue or sell any shares of capital stock of any class (whether
through the issuance or granting of options, warrants, commitments,
subscriptions, rights to purchase or otherwise) except for certain issuances
expressly provided for in the Merger Agreement; or (c) will not, and will not
permit any of its subsidiaries to, reclassify, combine, split, purchase or
redeem any shares of its capital stock or purchase or redeem any rights,
warrants or options to acquire any such shares.
 
  13. Effect of the Offer on the Market for the Shares, Exchange Listing;
Exchange Act Registration. The purchase of Shares by the Purchaser pursuant to
the Offer will reduce the number of Shares that might otherwise trade publicly
and will reduce the number of holders of Shares, which could adversely affect
the liquidity and market value of the remaining Shares held by the public. The
Parent believes, however, that, following the consummation of the Offer, the
Shares will continue to meet the standards for continued listing on the NYSE.
 
  The Shares are currently "margin securities," as such term is defined under
the rules of the Board of Governors of the Federal Reserve System, which has
the effect, among other things, of allowing brokers to extend credit on the
collateral of such securities. It is likely that the Shares will continue to
be "margin securities" following consummation of the Offer.
 
 
                                      29
<PAGE>
 
  The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the
Commission if the Shares are not listed on a national securities exchange and
there are fewer than 300 record holders. The termination of the registration
of the Shares under the Exchange Act would substantially reduce the
information required to be furnished by the Company to holders of Shares and
to the Commission and would make certain provisions of the Exchange Act, such
as the short-swing profit recovery provisions of Section 16(b), the
requirement of furnishing a proxy statement in connection with stockholders'
meetings and the requirements of Rule 13e-3 under the Exchange Act with
respect to "going private" transactions, no longer applicable to the Shares.
In addition, "affiliates" of the Company and persons holding "restricted
securities" of the Company may be deprived of the ability to dispose of such
securities pursuant to Rule 144 promulgated under the Securities Act of 1933,
as amended. If registration of the Shares under the Exchange Act were
terminated, the Shares would no longer be "margin securities" or be eligible
for NYSE listing. The Purchaser currently intends to seek to cause the Company
to terminate the registration of the Shares under the Exchange Act as soon
after consummation of the Offer as the requirements for termination of
registration are met. However, the Parent does not believe that the Company
will meet such requirements as a consequence of the Offer.
 
  14. Conditions to the Offer. Notwithstanding any other provision of the
Offer and subject to the terms of the Merger Agreement, the Purchaser will not
be required to accept for payment any Shares tendered pursuant to the Offer,
and may terminate the Offer and may postpone the acceptance for payment of and
payment for Shares tendered, if (i) any applicable waiting period under the
HSR Act shall not have expired or been terminated prior to the expiration of
the Offer, or (ii) immediately prior to the acceptance for payment of Shares,
any of the following conditions shall be reasonably determined by the Parent
to be existing:
 
    (a) there shall have been entered, enforced, promulgated or issued by any
  court or governmental, administrative or regulatory authority or agency of
  competent jurisdiction, domestic or foreign, any judgment, order,
  injunction or decree, (i) which makes illegal or prohibits or makes
  materially more costly the making of the Offer, the acceptance for payment
  of, or payment for, any Shares by the Parent, the Purchaser or any other
  affiliate of the Parent, or the consummation of any other transaction
  contemplated by the Merger Agreement, or imposes material damages in
  connection with any transaction contemplated by the Merger Agreement; (ii)
  which prohibits the ownership or operation by the Company or any of its
  subsidiaries or, as a result of the transactions contemplated by the Merger
  Agreement, the Parent and its subsidiaries, of all or any material portion
  of the business or assets of the Company, the Parent or any of their
  subsidiaries as a whole, or compels the Company, the Parent or any of their
  subsidiaries to dispose of or hold separate all or any material portion of
  the business or assets of the Company, the Parent or any of their
  subsidiaries as a whole; (iii) which imposes or confirms limitations on the
  ability of the Parent, the Purchaser or any other affiliate of the Parent
  to exercise effectively full rights of ownership of any Shares, including,
  without limitation, the right to vote any Shares acquired by the Purchaser
  pursuant to the Offer or otherwise on all matters properly presented to the
  Company's stockholders, including, without limitation, the approval and
  adoption of the Merger Agreement and the transactions contemplated by the
  Merger Agreement; (iv) requires divestiture by the Parent, the Purchaser or
  any other affiliate of the Parent of any Shares; or (v) which otherwise
  would have a Material Adverse Effect on the Company or, as a result of the
  transactions contemplated by the Merger Agreement, the Parent and its
  subsidiaries;
 
    (b) there shall have been any action taken, or any statute, rule,
  regulation, legislation or interpretation enacted, entered, enforced,
  promulgated, amended, issued or deemed applicable to (i) the Company or any
  subsidiary of the Company or, as a result of the transactions contemplated
  by the Merger Agreement, the Parent or any subsidiary or affiliate of the
  Parent, or (ii) any transaction contemplated by the Merger Agreement, by
  any legislative body, court, government or governmental, administrative or
  regulatory authority or agency, domestic or foreign, other than the routine
  application of the waiting period provisions of the HSR Act to the Offer or
  the Merger, which is reasonably likely to result, directly or indirectly,
  in any of the consequences referred to in clauses (i) through (v) of
  paragraph (a) above;
 
    (c) there shall have occurred and be continuing, (i) any general
  suspension of, or limitation on prices for, trading in securities on the
  NYSE other than a shortening of trading hours or any coordinated trading
 
                                      30
<PAGE>
 
  halt triggered solely as a result of a specified increase or decrease in a
  market index, (ii) a declaration of a banking moratorium or any suspension
  of payments in respect of banks in the United States, (iii) the
  commencement of a war, material armed hostilities or any other material
  international or national calamity involving the United States, or (iv) in
  the case of any of the foregoing existing at the time of the commencement
  of the Offer, a material acceleration or worsening thereof;
 
    (d) the representations or warranties of the Company set forth in the
  Merger Agreement shall not be true and correct, ignoring for this purpose
  any qualification as to materiality or Material Adverse Effect, as if such
  representations or warranties were made as of such time on or after the
  date of the Merger Agreement, except where the failure to be so true and
  correct, individually and in the aggregate would not have a Material
  Adverse Effect;
 
    (e) the Company shall have failed to perform in any material respect any
  obligation or to comply in any material respect with any agreement or
  covenant of the Company to be performed or complied with by it under the
  Merger Agreement;
 
    (f) the Merger Agreement shall have been terminated in accordance with
  its terms; or
 
    (g) the Purchaser and the Company shall have agreed that the Purchaser
  shall terminate the Offer or postpone the acceptance for payment of or
  payment for Shares thereunder;
 
which, in the reasonable good faith judgment of the Purchaser in any such
case, and regardless of the circumstances (including any action or inaction by
the Parent or any of its affiliates) giving rise to any such condition, makes
it inadvisable to proceed with such acceptance for payment or payment.
 
  The foregoing conditions are for the sole benefit of the Purchaser and the
Parent and may be asserted by the Purchaser or the Parent regardless of the
circumstances giving rise to any such condition or may be waived by the
Purchaser or the Parent in whole or in part at any time and from time to time
in their sole discretion. The failure by the Parent or the Purchaser at any
time to exercise any of the foregoing rights shall not be deemed a waiver of
any such right; the waiver of any such right with respect to particular facts
and other circumstances shall not be deemed a waiver with respect to any other
facts and circumstances; and each such right shall be deemed an ongoing right
that may be asserted at any time and from time to time.
 
  15. Certain Legal Matters and Regulatory Approvals.
 
  General. Based upon an examination of publicly available information with
respect to the Company and the representations and warranties of the Company
contained in the Merger Agreement, neither the Purchaser nor the Parent is
aware of any license or other regulatory permit that appears to be material to
the business of the Company and its subsidiaries, taken as a whole, which
might be adversely affected by the acquisition of Shares by the Purchaser
pursuant to the Offer, or, except as set forth below, of any approval or other
action by any domestic (federal or state) or foreign governmental,
administrative or regulatory authority or agency which would be required prior
to the acquisition of Shares by the Purchaser pursuant to the Offer. Should
any such approval or other action be required, it is the Purchaser's present
intention to seek such approval or action. The Purchaser does not currently
intend, however, to delay the purchase of Shares tendered pursuant to the
Offer pending the outcome of any such action or the receipt of any such
approval. There can be no assurance that any such approval or other action, if
needed, would be obtained without substantial conditions or that adverse
consequences might not result to the business of the Company, the Purchaser or
the Parent or that certain parts of the businesses of the Company, the
Purchaser or the Parent might not have to be disposed of or held separate or
other substantial conditions complied with in order to obtain such approval or
other action or in the event that such approval was not obtained or such other
action was not taken. The Purchaser's obligation under the Offer to accept for
payment and pay for Shares is subject to certain conditions, including
conditions relating to the legal matters discussed in this "Section 15.
Certain Legal Matters and Regulatory Approvals." See "Section 14. Conditions
to the Offer."
 
  Litigation. Following the March 9, 1998 announcement of the proposed
acquisition of the Company by the Parent and the Purchaser, five putative
class actions on behalf of stockholders of the Company were filed in
 
                                      31
<PAGE>
 
the Delaware Court of Chancery against the Company, the Company's directors
and the Parent. The plaintiffs in those actions allege, among other things,
that the director defendants have agreed to a buyout of the Company at an
inadequate price, that they have failed to provide the Company's stockholders
with all necessary information about the value of the Company, that they
failed to make an informed decision as no market check of the Company's value
was obtained, and that the acquisition is structured to ensure that
stockholders will tender their shares and is coercive. Plaintiffs seek to
enjoin the acquisition or to rescind it in the event that it is consummated
and to cause the Company to implement a "full and fair" auction for the
Company. Plaintiffs also seek compensatory damages in an unspecified amount,
costs and disbursements, including attorneys' fees, and such other relief as
the Court deems appropriate.
 
  State Takeover Laws. A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable
to attempts to acquire securities of corporations that are incorporated or
have assets, stockholders, executive offices or places of business in those
states. In 1982, in Edgar v. MITE Corp., the Supreme Court of the United
States held that the Illinois Business Takeover Act, which involved state
securities laws that made the takeover of certain corporations more difficult,
imposed a substantial burden on interstate commerce and was therefore
unconstitutional. However, in 1987, in CTS Corp. v. Dynamics Corp. of America,
the Supreme Court of the United States held that a state may, as a matter of
corporate law and, in particular, those laws concerning corporate governance,
constitutionally disqualify a potential acquirer from voting on the affairs of
a target corporation without prior approval of the remaining stockholders;
provided that the laws were applicable only under certain conditions.
 
  Section 203 of the DGCL limits the ability of a Delaware corporation to
engage in business combinations with "interested stockholders" (defined
generally as any person that directly or indirectly beneficially owns 15% or
more of the outstanding voting stock of the subject corporation) for three
years following the date such person became an "interested stockholder,"
unless, among other things, the board of directors of the subject corporation
has given its prior approval of either the transaction in which such person
became an interested stockholder or the business combination. The Company has
represented in the Merger Agreement that it approved the Merger Agreement and
the transactions contemplated thereby, including the Offer and the Merger, and
has taken all appropriate action so that neither the Parent nor the Purchaser
will be an "interested stockholder" within the meaning of Section 203 of the
DGCL by virtue of the Parent, the Purchaser and the Company entering into the
Merger Agreement and consummating the transactions contemplated thereby.
 
  The Company, directly or through subsidiaries, conducts business in a number
of states throughout the United States, some of which have enacted takeover
laws. The Purchaser does not know whether any of these laws will, by their
terms, apply to the Offer or the Merger and has not complied with any such
laws. Should any person seek to apply any state takeover law, the Purchaser
will take such action as then appears desirable, which may include challenging
the validity or applicability of any such statute in appropriate court
proceedings. In the event it is asserted that one or more state takeover laws
is applicable to the Offer or the Merger, and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer, the
Purchaser might be required to file certain information with, or receive
approvals from, the relevant state authorities. In addition, if enjoined, the
Purchaser might be unable to accept for payment any Shares tendered pursuant
to the Offer, or be delayed in continuing or consummating the Offer and the
Merger. In such case, the Purchaser may not be obligated to accept for payment
any Shares tendered. See "Section 14. Conditions to the Offer."
 
  Antitrust. Under the HSR Act and the rules that have been promulgated
thereunder by the Federal Trade Commission (the "FTC"), certain acquisition
transactions may not be consummated unless certain information has been
furnished to the Antitrust Division of the Department of Justice (the
"Antitrust Division") and the FTC and certain waiting period requirements have
been satisfied. The acquisition of Shares by the Purchaser pursuant to the
Offer is subject to such requirements.
 
  The Company and the Parent expect to file Premerger Notification and Report
Forms in connection with the purchase of Shares pursuant to the Offer with the
Antitrust Division and the FTC on or about Monday, March 16, 1998. Under the
provisions of the HSR Act applicable to the Offer, the purchase of Shares
pursuant to the
 
                                      32
<PAGE>
 
Offer may not be consummated until the expiration of a 15-calendar day waiting
period following the filing by the Parent. Accordingly, if the forms are filed
on March 16, 1998, the waiting period under the HSR Act applicable to the
purchase of Shares pursuant to the Offer will expire at 11:59 p.m., New York
City time, on March 31, 1998, unless such waiting period is earlier terminated
by the FTC and the Antitrust Division or extended by a request from the FTC or
the Antitrust Division for additional information or documentary material
prior to the expiration of the waiting period. If the acquisition of Shares is
delayed pursuant to a request by the FTC or the Antitrust Division for
additional information or documentary material pursuant to the HSR Act, the
purchase of and payment for Shares will be deferred until 10 days after the
request is substantially complied with, unless the extended period expires on
or before the date when the initial 15-day period would otherwise have
expired, or unless the waiting period is sooner terminated by the FTC and the
Antitrust Division. Only one extension of such waiting period pursuant to a
request for additional information is authorized by the HSR Act and the rules
promulgated thereunder, except by court order. Any such extension of the
waiting period will not give rise to any withdrawal rights not otherwise
provided for by applicable law. See "Section 4. Withdrawal Rights." It is a
condition to the Offer that the waiting period applicable under the HSR Act to
the Offer expire or be terminated. See "Section 14. Conditions to the Offer."
So long as the Merger Agreement is in effect and any applicable waiting period
under the HSR Act has not expired or been terminated, the Purchaser is
obligated to extend the Offer from time to time for a period or successive
periods, each not to exceed ten business days after the previously scheduled
Expiration Date.
 
  The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares
by the Purchaser pursuant to the Offer. At any time before or after the
purchase of Shares pursuant to the Offer by the Purchaser, the FTC or the
Antitrust Division could take such action under the antitrust laws as it deems
necessary or desirable in the public interest, including seeking to enjoin the
purchase of Shares pursuant to the Offer or seeking the divestiture of Shares
purchased by the Purchaser or the divestiture of substantial assets of the
Parent, the Company or their respective subsidiaries. Private parties and
state attorneys general may also bring legal action under federal or state
antitrust laws under certain circumstances. Based upon an examination of
information available to the Parent relating to the businesses in which the
Parent, the Company and their respective subsidiaries are engaged, the Parent
and the Purchaser believe that the Offer will not violate the antitrust laws.
Nevertheless, there can be no assurance that a challenge to the Offer on
antitrust grounds will not be made or, if such a challenge is made, what the
result would be. See "Section 14. Conditions to the Offer" for certain
conditions to the Offer.
 
  In addition, the antitrust and competition laws of certain foreign
jurisdictions require (or, in some instances, provide for on a voluntary
basis) notification of the transaction and the observance of pre-consummation
waiting periods. The Company and the Parent will make any such required
filings (and, if deemed in the Company's and the Parent's interests, any such
voluntary filings) with the appropriate antitrust and competition authorities
contemporaneously with their filings under the HSR Act or shortly thereafter.
Based upon an examination of information available to the Parent relating to
the businesses in which the Parent, the Company and their respective
subsidiaries are engaged, the Parent and the Purchaser believe that the Offer
will not violate any such foreign antitrust and competition laws.
Nevertheless, there can be no assurance that a challenge to the Offer will not
be made on antitrust or competition grounds or, if such a challenge were made,
what the result would be.
 
  16. Fees and Expenses. Except as set forth below, the Purchaser will not pay
any fees or commissions to any broker, dealer or other person for soliciting
tenders of Shares pursuant to the Offer.
 
  Credit Suisse First Boston is acting as Dealer Manager in connection with
the Offer and as financial advisor to the Parent in connection with the
Parent's proposed acquisition of the Company, for which services Credit Suisse
First Boston will receive customary compensation. The Parent also has agreed
to reimburse Credit Suisse First Boston for its out-of-pocket expenses,
including the fees and expenses of legal counsel and other advisors, incurred
in connection with its engagement, and to indemnify Credit Suisse First Boston
and certain related persons against certain liabilities and expenses in
connection with its engagement, including certain liabilities under the
federal securities laws. In the ordinary course of business, Credit Suisse
First Boston and its affiliates
 
                                      33
<PAGE>
 
may actively trade the debt and equity securities of the Parent and the
Company for their own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.
 
  The Purchaser and the Parent have retained D.F. King & Co., Inc., as the
Information Agent, and First Chicago Trust Company of New York, as the
Depositary, in connection with the Offer. The Information Agent may contact
holders of Shares by mail, telephone, telex, telecopy, telegraph and personal
interview and may request banks, brokers, dealers and other nominee
stockholders to forward materials relating to the Offer to beneficial owners.
 
  For acting as Information Agent in connection with the Offer, D.F. King &
Co., Inc. will be paid reasonable and customary compensation and will also be
reimbursed for certain out-of-pocket expenses and may be indemnified against
certain liabilities and expenses in connection with the Offer, including
certain liabilities under the federal securities laws. The Purchaser will pay
the Depositary reasonable and customary compensation for its services in
connection with the Offer, plus reimbursement for out-of-pocket expenses, and
will indemnify the Depositary against certain liabilities and expenses in
connection therewith, including under federal securities laws. Brokers,
dealers, commercial banks and trust companies will be reimbursed by the
Purchaser for customary handling and mailing expenses incurred by them in
forwarding material to their customers.

meeting of the Company's stockholders then scheduled.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered

title thereto and to all Distributions, free and clear of all liens,
restrictions, charges and encumbrances, and that none of such Shares and
Distributions will be subject to any adverse claim. The undersigned, upon
request, shall execute and deliver all additional documents deemed by the
Depositary or the Purchaser to be necessary or desirable to complete the sale,
assignment and transfer of the Shares tendered hereby and all Distributions.
In addition, the undersigned shall remit and transfer promptly to the
Depositary for the account of the Purchaser all Distributions in respect of
the Shares tendered hereby, accompanied by appropriate documentation of
transfer, and pending such remittance and transfer or appropriate assurance
thereof, the Purchaser shall be entitled to all rights and privileges as owner
of each such Distribution and may withhold the entire purchase price of the
Shares tendered hereby, or deduct from such purchase price the amount or value
of such Distribution as determined by the Purchaser in its sole discretion.

must be guaranteed by a financial institution (including most commercial
banks, savings and loan associations and brokerage houses) that is a
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange
Medallion Program (an "Eligible Institution") unless (i) this Letter of
Transmittal is signed by the registered holder(s) of the Shares (which term,
for purposes of this document, shall include any participant in the Book-Entry

owner of Shares) tendered hereby and such holder(s) has (have) not completed
the box entitled "Special Payment Instructions" or the box entitled "Special
Delivery Instructions" above or (ii) such Shares are tendered for the account
of an Eligible Institution. See Instruction 5.
 
  2. Delivery of Letter of Transmittal and Share Certificates. This Letter of
Transmittal is to be used either if Share Certificates are to be forwarded
herewith or, unless an Agent's Message is utilized, if Shares are to be
delivered by book-entry transfer pursuant to the procedure set forth in
"Section 3. Procedures for Accepting the Offer and Tendering Shares" of the
Offer to Purchase. Share Certificates evidencing all physically tendered
Shares, or a confirmation of a book-entry transfer into the Depositary's
account at the Book-Entry Transfer Facility of all Shares delivered by book-
entry transfer as well as a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), or, in the case of a book-entry transfer,
an Agent's Message, and any other documents required by this Letter of
Transmittal, must be received by the Depositary at one of its addresses set
forth above prior to the Expiration Date. If Share Certificates are forwarded
to the Depositary in multiple deliveries, a properly completed and duly
executed Letter of Transmittal must accompany each such delivery. Stockholders
whose Share Certificates are not immediately available, who cannot deliver
their Share Certificates and all other required documents to the Depositary
prior to the Expiration Date or who cannot complete the procedure for delivery
by book-entry transfer on a timely basis may tender their Shares pursuant to
the guaranteed delivery procedure described in "Section 3. Procedures for
Accepting the Offer and Tendering Shares" of the Offer to Purchase. Pursuant
to such procedure: (i) such tender must be made by or through an Eligible
Institution; (ii) a properly completed and duly executed Notice of Guaranteed
Delivery, substantially in the form made available by the Purchaser, must be
received by the Depositary prior to the Expiration Date; and (iii) the Share
Certificates evidencing all physically delivered Shares in proper form for
transfer by delivery, or a confirmation of a book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility of all Shares
delivered by book-entry transfer, in each case together with a Letter of
Transmittal (or a facsimile thereof), properly completed and duly executed,
with any required signature guarantees, or, in the case of a book-entry
transfer, an Agent's Message, and any other documents required by this Letter
of Transmittal, must be received by the Depositary within three New York Stock
Exchange, Inc. trading days after the date of execution of such Notice of
Guaranteed Delivery, all as described in "Section 3. Procedures for Accepting
the Offer and Tendering Shares" of the Offer to Purchase.
 
  The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility
has received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.
 
  THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND
THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
DEPOSITARY. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
  No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. By execution of this Letter of
Transmittal (or a facsimile hereof), all tendering stockholders waive any
right to receive any notice of the acceptance of their Shares for payment.

  3. Inadequate Space. If the space provided herein under "Description of
Shares Tendered" is inadequate, the Share Certificate numbers, the number of
Shares evidenced by such Share Certificates and the number of Shares tendered
should be listed on a separate schedule and attached hereto.
 
  4. Partial Tenders (not applicable to stockholders who tender by book-entry
transfer). If fewer than all the Shares evidenced by any Share Certificate
delivered to the Depositary herewith are to be tendered hereby, fill in the
number of Shares which are to be tendered in the box entitled "Number of
Shares Tendered." In such cases, new Share Certificate(s) evidencing the
remainder of the Shares that were evidenced by the Share Certificates
delivered to the Depositary herewith will be sent to the person(s) signing
this Letter of Transmittal, unless otherwise provided in the box entitled
"Special Delivery Instructions" above, as soon as practicable after the
expiration or termination of the Offer. All Shares evidenced by Share
Certificates delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.
 
  5. Signatures on Letter of Transmittal; Stock Powers and Endorsements. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written
on the face of the Share Certificates evidencing such Shares without
alteration, enlargement or any other change whatsoever. Do not endorse the
back of the Share Certificates.
 
  If any Share tendered hereby is owned of record by two or more persons, all
such persons must sign this Letter of Transmittal.
 
  If any of the Shares tendered hereby are registered in the names of
different holders, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal (or facsimile thereof) as there are different
registrations of such Shares.
 
  If this Letter of Transmittal is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of Share Certificates or separate
stock powers are required, unless payment is to be made to, or Share
Certificates evidencing Shares not tendered or not purchased are to be issued
in the name of, a person other than the registered holder(s), in which case,
the Share Certificate(s) evidencing the Shares tendered hereby must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear(s) on such Share
Certificate(s). Signatures on such Share Certificate(s) and stock powers must
be guaranteed by an Eligible Institution.
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, the Share Certificate(s)
evidencing the Shares tendered hereby must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear(s) on such Share Certificate(s). Signatures on
such Share Certificate(s) and stock powers must be guaranteed by an Eligible
Institution.
 
  If this Letter of Transmittal or any Share Certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or
representative capacity, such person should so indicate when signing, and
proper evidence satisfactory to the Purchaser of such person's authority so to
act must be submitted.
 
  6. Stock Transfer Taxes. Except as otherwise provided in this Instruction 6,
the Purchaser will pay all stock transfer taxes with respect to the sale and
transfer of any Shares to it or its order pursuant to the Offer. If, however,
payment of the purchase price of any Shares purchased is to be made to, or
Share Certificate(s) evidencing Shares not tendered or not purchased are to be
issued in the name of, a person other than the registered holder(s), the
amount of any stock transfer taxes (whether imposed on the registered
holder(s), such other person or otherwise) payable on account of the transfer
to such other person will be deducted from the purchase price of such Shares
purchased, unless evidence satisfactory to the Purchaser of the payment of
such taxes, or exemption therefrom, is submitted. Except as provided in this
Instruction 6, it will not be necessary for transfer tax stamps to be affixed
to the Share Certificates evidencing the Shares tendered hereby.
 
  7. Special Payment and Delivery Instructions. If a check for the purchase
price of any Shares tendered hereby is to be issued, or Share Certificate(s)
evidencing Shares not tendered or not purchased are to be issued, in the name
of a person other than the person(s) signing this Letter of Transmittal or if
such check or any such Share Certificate
 
                                       7
<PAGE>
 
is to be sent to someone other than the person(s) signing this Letter of
Transmittal or to the person(s) signing this Letter of Transmittal but at an
address other than that shown in the box entitled "Description of Shares
Tendered" above, the appropriate boxes on this Letter of Transmittal must be
completed. Stockholders delivering Shares tendered hereby by book-entry
transfer may request that Shares not purchased be credited to such account
maintained at the Book-Entry Transfer Facility as such stockholder may
designate in the box entitled "Special Payment Instructions" above. If no such
instructions are given, all such Shares not purchased will be returned by
crediting the account at the Book-Entry Transfer Facility designated herein as
the account from which such Shares were delivered.
 
  8. Questions and Requests for Assistance or Additional Copies. Questions and
requests for assistance may be directed to the Information Agent or the Dealer
Manager at their respective addresses or telephone numbers set forth below.
Additional copies of the Offer to Purchase, this Letter of Transmittal and
other tender offer materials may be obtained from the Information Agent or the
Dealer Manager.
 
  9. Substitute Form W-9. Each tendering stockholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN") on the
Substitute Form W-9 which is provided under "Important Tax Information" below,
and to certify whether such stockholder is subject to backup withholding of
federal income tax. If a tendering stockholder has been notified by the
Internal Revenue Service that such stockholder is subject to backup
withholding, such stockholder must cross out item (2) of the Certification box
of the Substitute Form W-9, unless such stockholder has since been notified by
the Internal Revenue Service that such stockholder is no longer subject to
backup withholding. Failure to provide the information on the Substitute Form
W-9 may subject the tendering stockholder to 31% federal income tax
withholding on the payment of the purchase price of all Shares purchased from
such stockholder. If the tendering stockholder has not been issued a TIN and
has applied for one or intends to apply for one in the near future, such
stockholder should write "Applied For" in the space provided for the TIN in
Part I of the Substitute Form W-9, and sign and date the Substitute Form W-9.
If "Applied For" is written in Part I and the Depositary is not provided with
a TIN within 60 days, the Depositary will withhold 31% on all payments of the
purchase price to such stockholder until a TIN is provided to the Depositary.
 
  10. Lost, Destroyed or Stolen Certificates. If any Share Certificates have
been lost, destroyed or stolen, the stockholder should promptly notify Chase
Mellon Shareholder Services, L.L.C., the Company's transfer agent (toll-free
telephone number 1-800-777-3674). The stockholder will then be instructed by
the Depositary as to the steps that must be taken in order to replace the
Share Certificate(s). This Letter of Transmittal and related documents cannot
be processed until the procedure for replacing lost, destroyed or stolen Share
Certificates has been followed.
 
  11. Waiver of Conditions. Subject to the terms of the Merger Agreement (as
defined in the Offer to Purchase) the conditions of the Offer may be waived,
in whole or in part, by the Purchaser, in its sole discretion, at any time and
from time to time, in the case of any Shares tendered.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF), PROPERLY
COMPLETED AND DULY EXECUTED (TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES
AND SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER
REQUIRED DOCUMENTS) OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF
GUARANTEED DELIVERY, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE
EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
  Under the federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required by law to provide the Depositary (as payer)
with such stockholder's correct TIN on Substitute Form W-9 below. If such
stockholder is an individual, the TIN is such stockholder's social security
number. If the Depositary is not provided with the correct TIN, the
stockholder may be subject to a $50 penalty imposed by the Internal Revenue
Service. In addition, payments that are made to such stockholder with respect
to Shares purchased pursuant to the Offer may be subject to backup withholding
of 31%.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, such individual must submit a statement, signed under penalties of
perjury, attesting to such individual's exempt status. Forms of such
statements can be obtained from the Depositary. See the enclosed Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
                                       8
<PAGE>
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will
be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained from the Internal Revenue
Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of such stockholder's correct TIN by
completing the form below certifying that the TIN provided on Substitute Form
W-9 is correct (or that such stockholder is awaiting a TIN), and that (i) such
stockholder has not been notified by the Internal Revenue Service that he is
subject to backup withholding as a result of a failure to report all interest
or dividends or (ii) the Internal Revenue Service has notified such
stockholder that such stockholder is no longer subject to backup withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The stockholder is required to give the Depositary the social security
number or employer identification number of the record holder of the Shares
tendered hereby. If the Shares are in more than one name or are not in the
name of the actual owner, consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional guidance
on which number to report. If the tendering stockholder has not been issued a
TIN and has applied for a number or intends to apply for a number in the near
future, the stockholder should write "Applied For" in the space provided for
the TIN in Part I, and sign and dated the Substitute Form W-9. If "Applied
For" is written in Part I and the Depositary is not provided with a TIN within
60 days, the Depositary will withhold 31% of all payments of the purchase
price to such stockholder until a TIN is provided to the Depositary.

     backup withholding.
 
 Certificate Instructions--You must cross out item (2) above if you have
 been notified by the IRS that you are subject to backup withholding because
 of underreporting interest or dividends on your tax return. However, if

 you received another notification from the IRS that you are no longer
 subject to backup withholding, do not cross out item (2). (Also see
 instructions in the enclosed Guidelines.)

  are fair to, and in the best interests of, the Company and its stockholders
  and recommends that stockholders accept the Offer, tender their Shares
  pursuant to the Offer and adopt the Merger Agreement.

on behalf of) the holders of Shares in such state. In any jurisdiction where
the securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer shall be deemed to be made on behalf of
the Purchaser by Credit Suisse First Boston Corporation or one or more
registered brokers or dealers licensed under the laws of such jurisdiction.

 . Payments to partnerships not engaged in a trade or business in the U.S.
   and which have at least one nonresident partner.
 . Payments of patronage dividends where the amount received is not paid in
   money.
 . Payments made by certain foreign organizations.
 . Payments made to a nominee.
Payments of interest not generally subject to backup withholding include the
following:
 . Payments of interest on obligations issued by individuals. Note: You may
   be subject to backup withholding if this interest is $600 or more and is
   paid in the course of the payer's trade or business and you have not
   provided your correct taxpayer identification number to the payer.
 . Payments of tax-exempt interest (including exempt-interest dividends under
   section 852).

 . Payments on tax-free covenant bonds under section 1451.
 . Payments made by certain foreign organizations.
 . Payments made to a nominee.
Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT
TO THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS,
ALSO SIGN AND DATE THE FORM.
 Certain payments other than interest, dividends, and patronage dividends,
that are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under sections 6041, 6041A(a),
6045, and 6050A.
PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are
required to file tax returns. Beginning January 1, 1993, payers must generally
withhold 31% of taxable interest, dividend, and certain other payments to a
payee who does not furnish a taxpayer identification number to a payer.
Certain penalties may also apply.
 
PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you
fail to furnish your taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and
convincing evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.

This announcement is neither an offer to purchase nor a solicitation of an offer
to sell Shares. The Offer is made solely by the Offer to Purchase dated March
13, 1998 and the related Letter of Transmittal and is being made to all holders
of Shares. The Purchaser is not aware of any jurisdiction where the making of
the Offer is prohibited by administrative or judicial action pursuant to any
valid state statute. If the Purchaser becomes aware of any valid state statute
prohibiting the making of the Offer or the acceptance of Shares pursuant
thereto, the Purchaser will make a good faith effort to comply with such state
statute. If, after such good faith effort, the Purchaser cannot comply with
such state statute, the Offer will not be made to (nor will tenders be accepted
from or on behalf of) the holders of Shares in such state. In any jurisdiction
where the securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer shall be deemed to be made on behalf of the
Purchaser by Credit Suisse First Boston Corporation ("Credit Suisse First
Boston") or by one or more registered brokers or dealers licensed under the laws
of such jurisdiction.

                     Notice of Offer to Purchase for Cash

                       27,000,000 Shares of Common Stock

                             AMX Acquisition Corp.
                         a wholly owned subsidiary of
                          Aluminum Company of America


    AMX Acquisition Corp., a Delaware corporation (the "Purchaser") and a wholly
owned subsidiary of Aluminum Company of America, a Pennsylvania corporation (the
"Parent"), is offering to purchase up to 27,000,000 shares of common stock, par
value $.01 per share (the "Shares"), of Alumax Inc., a Delaware corporation (the
"Company"), at a price of $50.00 per Share, net to the seller in cash, upon the
terms and subject to the conditions set forth in the Offer to Purchase dated
March 13,1998 (the "Offer to Purchase") and in the related Letter of Transmittal
(which together constitute the "Offer").

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    The offer, proration period and withdrawal rights will expire at 12:00 
midnight, New York City time, on April 9, 1998, unless the offer is extended.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

    The Offer is conditioned upon, among other things, the waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, applicable
to the purchase of the Shares pursuant to the Offer having expired or been
terminated. The Offer is also subject to certain other conditions set forth in
the Offer to Purchase.

    The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of March 8, 1998 (the "Merger Agreement"), among the Parent, the Purchaser
and the Company. The Merger Agreement provides, among other things, that, upon
the terms and subject to the conditions set forth in the Merger Agreement,
following the purchase of Shares pursuant to the Offer, the Company will be
merged with and into the Purchaser (the "Merger"), which will be the surviving
corporation in the Merger. At the effective time of the Merger (the "Effective
Time"), each issued and outstanding Share (other than Shares owned by the
Parent, the Purchaser, any of their respective subsidiaries, the Company or any
subsidiary of the Company and other than Shares held by stockholders who shall
have exercised and perfected appraisal rights, if any, under the Delaware
General Corporation Law), will be converted into, and become exchangeable for,
the right to receive: (i) 0.6975 of a share of common stock, par value $1.00 per
share, of the Parent ("Parent Common Stock"), if the Purchaser purchases at
least 27,000,000 Shares or such other number of Shares which equals the 50%
Share Number (as defined in the Merger Agreement); or (ii) a combination of cash
and a fraction of a Share of Parent Common Stock, determined in accordance with
the Merger Agreement, if the Purchaser purchases fewer Shares than the 50% Share
Number. The Merger Agreement is more fully described in "Section 10. Background
of the Offer; Contacts with the Company; the Merger Agreement" of the Offer to
Purchase.

    The Board of Directors of the Company has unanimously (with one director
absent) approved the Merger Agreement and the transactions contemplated thereby,
determined that the terms of the Offer and the Merger are fair to, and in the
best interests of, the Company and its stockholders and recommends that
stockholders accept the Offer, tender their Shares pursuant to the Offer and
adopt the Merger Agreement.

    If more than 27,000,000 Shares are validly tendered prior to the Expiration
Date and not withdrawn, the Purchaser will accept for payment (and thereby
purchase) 27,000,000 Shares, on a pro rata basis, with adjustments to avoid
purchases of fractional Shares, based upon the number of Shares validly tendered
on or prior to the Expiration Date and not withdrawn by each tendering
stockholder. In the event that proration of tendered Shares is required, because
of the difficulty of determining the precise number of Shares properly tendered
and not withdrawn, the Purchaser does not expect that it will be able to
announce the final results of such proration or pay for any Shares until at
least five New York Stock Exchange, Inc. trading days after the Expiration Date.
Tendering stockholders will not receive payment for Shares accepted for payment
pursuant to the Offer until the final proration factor is known.

    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered to the Purchaser
(subject to any pro rata adjustment in accordance with the terms of the Offer in
the event more than 27,000,000 Shares are validly tendered in the Offer) and not
properly withdrawn as, if and when the Purchaser gives oral or written notice to
First Chicago Trust Company of New York (the "Depositary") of the Purchaser's
acceptance for payment of such Shares pursuant to the Offer. Upon the terms and
subject to the conditions of the Offer, payment for Shares accepted for payment
pursuant to the Offer will be made by deposit of the purchase price therefor
with the Depositary, which will act as agent for tendering stockholders for the
purpose of receiving payments from the Purchaser and transmitting such payments
to tendering stockholders whose Shares have been accepted for payment. Under no
circumstances will interest on the purchase price for Shares be paid, regardless
of any delay in making such payment. In all cases, payment for Shares tendered
and accepted for payment pursuant to the Offer will be made only after timely
receipt by the Depositary of (i) the certificates evidencing such Shares (the
"Share Certificates") or timely confirmation of a book-entry transfer of such
Shares into the Depositary's account at The Depository Trust Company pursuant to
the procedures set forth in "Section 3. Procedures for Accepting the Offer and
Tendering Shares" of the Offer to Purchase, (ii) the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or an Agent's Message (as defined in "Section 3.
Procedures for Accepting the Offer and Tendering Shares" of the Offer to
Purchase) in connection with a book-entry transfer, and (iii) any other
documents required under the Letter of Transmittal.

    Pursuant to the Merger Agreement, the Purchaser may, without the consent of
the Company, (i) extend the Offer if, at the Expiration Date, any of the
conditions to the Purchaser's obligation to accept for payment and to pay for
the Shares are not satisfied or waived, or (ii) extend the Offer for any period
required by any rule, regulation or interpretation of the Securities and
Exchange Commission or the staff thereof applicable to the Offer. So long as the
Merger Agreement is in effect and the applicable waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended, has not expired or
been terminated, the Purchaser has agreed to extend the Offer from time to time
for a period or successive periods, each not to exceed ten business days after
the previously scheduled Expiration Date. Any such extension will be followed as
promptly as practicable by public announcement thereof, such announcement to be
made no later than 9:00 a.m., New York City time, on the next business day after
the previously scheduled Expiration Date. During any such extension, Shares
previously tendered and not withdrawn will remain subject to the terms of the
Offer, including the right of a tendering stockholder to withdraw such Shares.

    Tenders of Shares made pursuant to the Offer are irrevocable except that
such Shares may be withdrawn at any time prior to 12:00 midnight, New York City
time, on April 9, 1998 (or the latest time and date at which the Offer, if
extended by the Purchaser, shall expire) (the "Expiration Date") and, unless
theretofore accepted for payment by the Purchaser pursuant to the Offer, may
also be withdrawn at any time after May 11, 1998. For a withdrawal to be
effective, a written, telegraphic or facsimile transmission notice of withdrawal
must be timely received by the Depositary at one of its addresses set forth on
the back cover page of the Offer to Purchase. Any such notice of withdrawal must
specify the name of the person who tendered the Shares to be withdrawn, the
number of Shares to be withdrawn and the name of the registered holder of such
Shares, if different from that of the person who tendered such Shares. If Share
Certificates evidencing Shares to be withdrawn have been delivered or otherwise

Alcoa to Acquire Alumax Inc.

          PITTSBURGH and ATLANTA, March 9, 1998 - Alcoa (NYSE: AA) and Alumax
Inc. (NYSE:  AMX) today announced they have entered into a definitive
agreement under which Alcoa will acquire all outstanding shares of Alumax for a
combination of cash and stock.

          Alcoa will commence the transaction with a cash tender offer for one-
half the outstanding Alumax shares at $50.00 per share.  The second step will be
a merger in which each remaining outstanding Alumax share will be converted into
0.6975 of a share of Alcoa common stock.  Based on the March 4, 1998 closing
price of Alcoa common stock, the transaction is valued at approximately $3.8
billion.  It is intended that the Alcoa shares to be issued in the second step
merger will be tax-free to Alumax shareholders.

          The combined company will have about 100,000 employees.  It will
operate in 250 locations in 30 countries with estimated 1998 revenues of $17.0
billion.

          In announcing the transaction.  Allen Born, Chairman and Chief
Executive Officer of Alumax, and Paul H. O'Neill, Chairman and Chief Executive
Officer of Alcoa, said:  "We are very pleased to announce this merger.  It
brings together two companies whose activities are very complementary which will
benefit customers, employees and shareholders.
<PAGE>
 
          "This combination will create economic efficiency for customers by
saving cost overlaps in management, marketing, transportation and research and
development while gaining additional new value through the combined technology
and operating know-how of the employees."

          Both companies' Boards of Directors have approved the tender offer,
which is expected to commence Friday, March 13, 1998.  It will be conditioned on
the expiration of antitrust waiting periods and other customary conditions.  The
merger, which has also been approved by the Board of Directors of each company,
is subject to certain additional conditions, including approval by stockholders
of Alumax owning a majority of the Alumax shares and other customary conditions.
The stockholders meeting to consider the merger is expected to be held in the
second quarter with a merger closing expected shortly thereafter.

          BT Wolfensohn is serving as financial advisor to Alumax and has
rendered a fairness opinion to Alumax's Board of Directors with respect to the
proposed transaction.  Credit Suisse First Boston Corporation is serving as
financial advisor to Alcoa and will act as dealer manager in the tender offer.

                             CLASS ACTION COMPLAINT
                             ----------------------

          Plaintiff, by his attorneys, alleges upon information and belief,
except with respect to his ownership of Alumax, Inc. ("AMX" or the "Company")
common stock and his suitability to serve as a class representative which is
alleged upon personal knowledge, as follows:

                                  THE PARTIES
                                  -----------
          1.   Plaintiff is and was at all times relevant to this action the
owner of shares of AMX common stock.
<PAGE>
 
          2.   Defendant AMX is a corporation organized and existing under the
laws of the State of Delaware with its principal offices in Atlanta, Georgia.
AMX produces and markets aluminum products.

          3.   Defendants Allen Born, J. Dennis Bonney, Harold Brown, L. Don
Brown, Pierre Des Marais II, James C. Huntington, Jr., W. Loeber Landau, Paul
Macavoy and Anne Wexler comprise the Board of Directors of AMX.  Allen Born is
also Chairman of the Board and Chief Executive Officer.  As officers and
directors of AMX, these individuals (hereinafter the "Individual Defendants")
owe fiduciary duties of good faith, fair dealing, due care and candor to
plaintiff and the other AMX public stockholders.

          4.   Defendant Aluminum Co. of America ("Alcoa") is a Pennsylvania
corporation which is an integrated aluminum company.

                            CLASS ACTION ALLEGATIONS
                            ------------------------

          5.   Plaintiff brings this case pursuant to Rule 23 of the Rules of
the Court of Chancery on behalf of himself and all other stockholders of the 
Company (except the Individual Defendants herein and any persons, firm, trust,
corporation, or other entity related to or affiliated with any of them and
their successors in interest), who are or will be threatened with injury arising
from defendants' actions as more fully described herein (the "Class").

                                       2
<PAGE>
 
          6.   This action is properly maintainable as a class action for the
following reasons:

               a.   The Class is so numerous that joinder of all members is
impracticable.  As of January 31, 1998, AMX had over 53 million shares of common
stock outstanding held by over 9 thousand shareholders of record.

               b.   The members of the Class are scattered throughout the United
States and are so numerous as to make it impracticable to bring them all before
this Court.

               c.   There are questions of law and fact which are common to the
Class and which predominate including, inter alia, the following:
                                       ----- ----                

                    (1) whether the defendants breached their fiduciary and
other common law duties which they owed to plaintiff and other members of the
Class; and

                    (2)  whether plaintiff and the other members of the Class
are being irreparably damaged.

               d.   The claims of plaintiff are typical of the claims of the
Class in that all members of the Class will be damaged by defendants' actions.

               e.   Plaintiff is committed to prosecuting this action and has
retained competent counsel experienced in litigation of this nature.  Plaintiff
is an adequate representative of the Class.

                                       3
<PAGE>
 
               f.   The prosecution of separate actions by or against
individual members of the Class would create a risk of inconsistent or varying
adjudications with respect to individual members of the Class.

               g.   Defendants have acted or refused to act on grounds generally
applicable to the Class, thereby making appropriate injunctive relief or
corresponding declaratory relief with respect to the Class as a whole.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------

          7.   On March 9, 1998, with no prior announcement that AMX was for
sale and no adequate market check, defendants announced that they had
unanimously agreed with defendant Alcoa to a two-tiered buyout of AMX.  The
first tier, will be a $50 cash purchase by Alcoa for a minimum of 50% of the
outstanding shares of AMX.  In the second tier, Alcoa will exchange .6975 shares
of his own stock for each remaining AMX share.  Alcoa will begin buying AMX
shares on Friday, March 13, 1998.

          8.   Defendants have not only agreed to a buyout of AMX at an
inadequate price, they have failed and are failing to provide the AMX
stockholders with all necessary information about the value of AMX.

          9.   The Individual Defendants' fiduciary obligations require them to:

                                       4
<PAGE>
 
               a.   undertake an appropriate evaluation of any bona fide
                                                               ---- ----
offers, and take appropriate steps to solicit all potential bids for the Company
or its assets or consider strategic alternatives;

               b.   act independently so that the interests of AMX's public
stockholders will be protected; and

               c.   adequately ensure that no conflicts of interest exist
between the Individual Defendants' own interests and their fiduciary
obligations to the public stockholders of AMX.

          10.  Because the Individual Defendants dominate and control the
business and corporate affairs of AMX, and are in possession of private
corporate information concerning its assets, business and future prospects,
there exists an imbalance and disparity of knowledge and economic power between
them and the public shareholders of AMX which makes it inherently unfair for
them to sell the Company before fully exploring the proposals described above
and alternative strategies for maximizing shareholder value.  Defendants have
failed to announce or implement strategies such as an active auction or open
bidding procedures best calculated to determine the worth of the Company.

          11.  By the acts, transactions and courses of conduct alleged herein,
the Individual Defendants, individually and as part of a common plan and scheme
in breach of their fiduciary duties and obligations, are attempting unfairly to

                                       5
<PAGE>
 
deprive plaintiff and other members of the Class of the highest premium which
they could realize in an acquisition transaction.

          12.  As a result of the actions of the Individual Defendants,
plaintiff and the other members of the Class have been and will be damaged in
that they have not and will not receive their fair proportion of the value of
AMX's assets and businesses and/or have been and will be prevented from
obtaining fair consideration for their shares of AMX's common stock.

          13.  Only through the exercise of this Court's equitable powers can
plaintiff be fully protected from the immediate and irreparable injury which
defendants' actions threaten to inflict.  Defendants are precluding the
shareholders' enjoyment of the full economic value of their investment by
failing to proceed expeditiously and in good faith to pursue a full and fair
auction for AMX.

          14.  Moreover, the transaction is structured to ensure that people
will tender their shares in order to avoid receiving the shares on the back-end
and is therefore coercive.

          15.  Unless enjoined by this Court, defendants will continue to breach
their fiduciary duties owed to plaintiff and the other members of the Class.

          16. Plaintiff and the Class have no adequate remedy at law.

          WHEREFORE, plaintiff demands judgment, as follows:

          A. Declaring this to be a proper class action;

                                       6
<PAGE>
 
          B.   Ordering defendants to carry out their fiduciary duties to
plaintiff and the other members of the Class by announcing their intention to:

               (i)  undertake an appropriate evaluation of alternatives designed
to maximize value for AMX's public stockholders; and

               (ii) adequately ensure that no conflicts of interest exist
between defendants' own interests and their fiduciary obligation to the public
stockholders or, if such conflicts exist, to ensure that all of the conflicts
would be resolved in the best interests of AMX's public stockholders.

          C.   Ordering defendants jointly and severally to take all steps to
enhance AMX's value as a merger or acquisition candidate, to implement a full
and fair auction for AMX, to agree only to a non-coercive transaction which
maximizes value, and to provide AMX's stockholders with all information material
to their determination whether or not to tender or vote in favor of the merger.

          D.   Ordering defendants, jointly and severally, to account to
plaintiff and the Class for all damages suffered and to be suffered by Class
members as a result of the acts alleged herein;

          E.   Awarding plaintiff the costs and disbursements of the action,
including allowance for plaintiff's reasonable attorneys' and experts' fees; and

          F.   Granting such other and further relief as may be just and proper
in the premises.

                             CLASS ACTION COMPLAINT
                             ----------------------

          Plaintiff alleges upon information and belief, except for paragraph 1
hereof, which is alleged upon knowledge, as follows:

          1.   Plaintiff has been the owner of the common stock of Alumax Inc.
("Alumax" or the "Company") since prior to the transaction herein complained of
and continuously to date.

          2.   Alumax is a corporation duly organized and existing under the
laws of the State of Delaware.  The Company is an integrated aluminum company
that 
<PAGE>
 
produces and sells primary aluminum and semifabricated products such as sheet,
plate, extrusions and foil, and other fabricated products.

          3.   Aluminum Company of America ("Alcoa") is a Delaware corporation
based in Pittsburgh, Pennsylvania and is the world's largest integrated aluminum
concern.

          4.   Defendant Allen Born is Chairman of the Board and Chief Executive
Officer of the Company.

          5.   Defendants Harold Brown, Pierre Des Marias, II, J. Dennis Bonney,
L. Don Brown, James C. Huntington, Jr., W. Loeber Landau, Allen Born, Paul
McAvoy, and Anne Wexler are Directors of Alumax.

          6.   The Individual Defendants are in a fiduciary relationship with
Plaintiff and the other public stockholders of Alumax and owe them the highest
obligations of good faith and fair dealing.

                            CLASS ACTION ALLEGATIONS
                            ------------------------

          7.   Plaintiff brings this action on its own behalf and as a class
action, pursuant to Rule 23 of the Rules of the Court of Chancery, on behalf of
all common stockholders of the Company (except the defendants herein and any
person, firm, trust, corporation, or other entity related to or affiliated with
any of the defendants) and their successors in interest, who are or will be
threatened with injury arising from defendants' actions as more fully described
herein.

                                       2
<PAGE>
 
          8. This action is properly maintainable as a class action because:

             (a) The class is so numerous that joinder of all members is
impracticable.  As of March 31, 1997, there were approximately 54,913,013 shares
of Alumax common stock outstanding owned by hundreds, if not thousands, of
record and beneficial holders;

             (b) There are questions of law and fact which are common to the
class including, inter alia, the following: (i) whether defendants have breached
                 ----- ----
their fiduciary and other common law duties owed by them to plaintiff and the
members of the class; and (ii) whether the class is entitled to injunctive
relief or damages as a result of the wrongful conduct committed by defendants.
 
             (c) Plaintiff is committed to prosecuting this action and has
retained competent counsel experienced in litigation of this nature.  The claims
of the plaintiff are typical of the claims of other members of the class and
plaintiff has the same interests as the other members of the class.  Plaintiff
will fairly and adequately represent the class.
  
             (d) Defendants have acted in a manner which affects plaintiff and
all members of the class alike, thereby making appropriate injunctive relief
and/or corresponding declaratory relief with respect to the class as a whole.

             (e) The prosecution of separate actions by individual members of
the Class would create a risk of inconsistent or varying adjudications with


                                       3
<PAGE>
 
respect to individual members of the Class, which would establish incompatible
standards of conduct for defendants, or adjudications with respect to individual
members of the Class which would, as a practical matter, be dispositive of the
interests of other members or substantially impair or impede their ability to
protect their interests.

          9.  On March 9, 1998, Alumax and Alcoa announced that they had
entered into a definitive merger agreement whereby Alcoa will acquire Alumax in
a transaction valued at $3.8 billion.  Under the terms of the transaction as
presently proposed, Alcoa will first commence a cash tender offer for one half
of Alumax's outstanding common shares at a price of $50 per share.  The second
step of the proposed transaction will be a merger in which the remaining
outstanding shares of Alumax will each be converted into 0.6975 of a share of
Alcoa common stock, which values them at $49.96 per share based on Alcoa's
closing price of Friday, March 6, 1998.

          10.  The proposed transaction is structured to coerce the
shareholders of Alumax into tendering their shares in the first step of the
proposed transaction, in order to avoid the risk of receiving the lesser and
uncertain consideration offered in the second step merger.

                                       4
<PAGE>
 
          11.  By entering into the agreement with Alcoa, the Alumax Board has
initiated a process to sell the Company which imposes heightened fiduciary
responsibilities and requires enhanced scrutiny by the Court.  However, the
terms of the proposed transaction were not the result of an auction process or
active market check; they were arrived at without a full and thorough
investigation by the Individual Defendants; and they are intrinsically unfair
and inadequate from standpoint of the Alumax shareholders.

          12.  The Individual Defendants failed to make an informed decision,
as no market check of the Company's value was obtained.  In agreeing to the
merger, the Individual Defendants failed to properly inform themselves of
Alumax's highest transactional value.

          13.  The Individual Defendants have violated the fiduciary duties
owed to the public shareholders of Alumax.  The Individual Defendants' agreement
to the terms of the transaction, its timing, and the failure to auction the
Company and invite other bidders, and defendants' failure to provide a market
check demonstrate a clear absence of the exercise of due care and of loyalty to
Alumax's public shareholders.

          14.  The Individual Defendants' fiduciary obligations under these
circumstances require them to:

                                       5
<PAGE>
 
               (a) Undertake an appropriate evaluation of Alumax's net worth 
as a merger/acquisition candidate; and

               (b) Engage in a meaningful auction with third parties in an
attempt to obtain the best value for Alumax's public shareholders.

          15.  The Individual Defendants have breached their fiduciary duties by
reason of the acts and transactions complained of herein, including their
decision to merge with Alcoa without making the requisite effort to obtain the
best offer possible.

          16.  Plaintiff and other members of the Class have been and will be
damaged in that they have not and will not receive their fair proportion of the
value of Alumax's assets and business, and will be prevented from obtaining fair
and adequate consideration for their shares of Alumax common stock.

          17.  The consideration to be paid to class members in the proposed
merger is unfair and inadequate because, among other things:

               (a) The intrinsic value of Alumax's common stock is materially in
excess of the amount offered for those securities in the merger giving due
consideration to the anticipated operating results, net asset value, cash flow,
and profitability of the Company;

               (b) The merger price is not the result of an appropriate
consideration of the value of Alumax because the Alumax Board approved the

                                       6
<PAGE>
 
proposed merger without undertaking steps to accurately ascertain Alumax's value
through open bidding or at least a "market check mechanism"; and

               (c) By entering into the agreement with Alcoa, the Individual
Defendants have allowed the price of Alumax stock to be capped, thereby 
depriving plaintiff and the Class of the opportunity to realize any increase in
the value of Alumax stock.

          18.  By reason of the foregoing, each member of the Class will suffer
irreparable injury and damages absent injunctive relief by this Court.

          19.  Alcoa is named as a defendant in order to permit the Court to
grant complete relief.

          20.  Plaintiff and other members of the Class have no adequate remedy
at law.

     WHEREFORE, plaintiff and members of the Class demand judgment against
defendants as follows:

     a. Declaring that this action is properly maintainable as a class action
        and certifying plaintiff as the representative of the Class;

     b. Preliminarily and permanently enjoining defendants and their counsel,
        agents, employees and all persons acting under, in concert with, or for
        them, from proceeding with, consummating, or closing the proposed
        transaction;

                                       7
<PAGE>
 
     c. In the event that the proposed transaction is consummated, rescinding it
        and setting it aside, or awarding rescissory damages to the Class;

     d. Awarding compensatory damages against defendants, individually and
        severally, in an amount to be determined at trial, together with pre-
        judgement and post-judgment interest at the maximum rate allowable by
        law, arising from the proposed transaction;

     e. Awarding plaintiff its costs and disbursements and reasonable allowances
        for fees of plaintiff's counsel and experts and reimbursement of
        expenses; and

     f. Granting plaintiff and the Class such other and further relief as the
        Court may deem just and proper.

                             CLASS ACTION COMPLAINT
                             ----------------------


          Plaintiff, by his attorneys, alleges upon information and belief,
except as to paragraph 1, which plaintiff alleges upon knowledge, as follows:

          1.  Plaintiff Alfred Ronconi ("plaintiff" or "Ronconi") is the owner
of shares in Alumax, Inc. ("Alumax" or the "Company") and has owned such shares
at all times relevant hereto.  Plaintiff brings this action as a class action on
behalf of himself and all other similarly situated owners of Alumax shares to
enjoin the proposed acquisition of Alumax by defendant Aluminum Co. of America
("Alcoa"), or alternatively, to rescind the transaction and/or recover 
<PAGE>
 
damages in the event that the transaction is consummated.

          2.  Alumax is a publicly traded corporation duly existing and
organized under the laws of the State of Delaware, with its principal offices
located at 3424 Peachtree Road, North East, Suite 2100, Atlanta, Georgia, 30326.
The Company is the market leader in extrusions, or processed metal products.
Alumax is and at all times relevant hereto was listed on the New York Stock
Exchange ("NYSE") trading under the symbol of "AMX".  As of January 31, 1998,
Alumax had 53,424,939 shares issued and outstanding.

          3.  Defendant Allen Born ("Born") is and at all times relevant hereto
has been Chairman of the Board and Chief Executive Officer of Alumax.

          4.  Defendant J. Dennis Bonney ("Bonney") is and at all times relevant
hereto has been a director of Alumax.

          5.  Defendant Harold Brown ("H. Brown") is and at all times relevant
hereto has been a director of Alumax.

          6.  Defendant L. Don Brown ("L. Brown") is and at all times relevant
hereto has been a director of Alumax.

          7.  Defendant Pierre Des Marais, II ("Des Marais") is and at all times
relevant hereto has been a director of Alumax.

          8.  Defendant James C. Huntington, Jr. ("Huntington") is and at all
times relevant hereto has been a director of Alumax.

                                       2
<PAGE>
 
          9.   Defendant W. Loeber Landau ("Landau") is and at all
times relevant hereto has been a director of Alumax.

          10.  Defendant Paul W. Macavoy ("Macavoy") is and at all
times relevant hereto has been a director of Alumax.

          11.  the defendants referred to in paragraphs 3 through 10 are
collectively referred to herein as the "Individual Defendants."

          12.  By reason of the above Individual Defendants' positions with the
Company as officers and/or directors, said individuals are in a fiduciary
relationship with plaintiff and the other public stockholders of Alumax, and owe
plaintiff and the other members of the class the highest obligations of good
faith, fair dealing, due care, loyalty and full, candid and adequate disclosure.

                            CLASS ACTION ALLEGATIONS
                            ------------------------

          13.  Plaintiff brings this action on his own behalf and as a class
action, pursuant to Rule 23 of the Rules of the Court of Chancery, on behalf of
himself and holders of Alumax common stock (the "Class").  Excluded from the
Class are defendants herein and any person, firm, trust, corporation or other
entity related to or affiliated with any of the defendants.

          14.  This action is properly maintainable as a class action.

          15.  The Class is so numerous that joinder of all members is
impracticable.  As of January 31, 1998, Alumax had 53,424,939 shares issued
and outstanding.

                                       3
<PAGE>
 
          16.  There are questions of law and fact which are common to the 
Class including, inter alia, the following:
                 ----- ----                

               a.  whether defendants have engaged in conduct constituting
unfair dealing to the detriment of the Class;

               b.  whether the merger is grossly unfair to the Class;

               c.  whether defendants are engaging in self-dealing to benefit
themselves;

               d.  whether plaintiff and the other members of the Class would be
irreparably damaged were the transactions complained of herein consummated; and

               e.  whether defendants have breached their fiduciary and other
common law duties owed by them to plaintiff and the other members of the Class.

          17.  Plaintiff is committed to prosecuting this action and has
retained competent counsel experienced in litigation of this nature.
Plaintiff's claims are typical of the claims of the other members of the Class
and plaintiff has the same interests as the other members of the Class.
Accordingly, plaintiff is an adequate representative of the Class and will
fairly and adequately protect the interests of the Class.

          18.  Plaintiff anticipates that there will be no difficulty in the
management of this litigation.

          19.  Defendants have acted on grounds generally applicable to the
Class with respect to the matters complained of herein, thereby making
appropriate the relief sought herein with respect to the Class as a whole.

                                       4
<PAGE>
 
          20.  The prosecution of separate actions by individual members of the
Class would create the risk of inconsistent or varying adjudications with
respect to individual members of the Class which would establish incompatible
standards of conduct for defendants, or adjudications with respect to individual
members of the Class which would as a practical matter be dispositive of the
interests of the other members not parties to the adjudications or substantially
impair or impede their ability to protect their interests.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------

          21.  This action seeks to enjoin the consummation of, or in the
alternative, damages resulting from, the acquisition/merger between Alumax and
Alcoa.

          22.  Alcoa will commence the transaction with a cash tender offer for
one-half the outstanding Alumax shares at $50.00 per share on March 13, 1998,
followed by a forced merger in which each remaining Alumax share will be
exchanged for 0.6975 of a share of Alcoa common stock.

          23.  If the merger is completed, the combined company will retain the
Alcoa name, will have 100,000 employees, operate at over 250 locations in 30
countries and have estimated annual revenues of about $17.0 billion.

          24.  The merger consideration to be paid to Class members is unfair
and inadequate because, among other things:

               a.  the consideration agreed upon did not result from an
appropriate consideration of the value of Alumax as the Individual Defendants
were presented with, and asked to 

                                       5
<PAGE>
 
evaluate, the proposed merger without any attempt to sufficiently ascertain the
true value of Alumax through open bidding or a "market check" mechanism;

               b.  the price received by Alumax shareholders does not reflect an
adequate premium considering that the intrinsic value of Alumax common stock is
materially in excess of the amount offered giving due consideration to the
Company's continuing economic improvement, ongoing operating efficiencies,
market share initiatives, and varied product offerings.

          25.  The Individual Defendants have thus far failed to announce any
active auction or open bidding procedures best calculated to maximize
shareholder value and have, instead, agreed to the merger which will only serve
to inhibit the maximization of shareholder value.

          26.  In addition, defendants have agreed to a transaction which by its
very structure is coercive and unfair to the Class.  Because the acquisition of
the remaining 50% of Alumax stock will be paid in Alcoa stock, rather than cash,
the shareholders will be coerced into tendering their shares in order to receive
the far superior cash offer portion of the consideration offered in the merger.
Thus, the transaction by its very terms is unfair and coercive to the Class.

          27.  The defendants have violated their fiduciary duties owed to the
public shareholders of Alumax and have acted to put their personal interests
ahead of the interests of Alumax's shareholders.

          28.  The Individual Defendants were and are under a duty:

               a.  to fully inform themselves before taking, or agreeing to
refrain from taking, action;

                                       6
<PAGE>
 
               b.  to elicit, promote, investigate, consider, evaluate and
inform themselves with respect to reasonable alternative transactions and/or
bona fide offers for the Company;
- ---- ----

               c.  to act in the interests of the equity owners;

               d.  not to erect unreasonable barriers to perceived threats of an
acquisition of the Company, or of control of the Company, by a third party;

               e.  not to act on their own personal self-interest or in the
personal interest of other board members;

               f.  to maximize shareholder value;

               g.  to obtain the best financial and other terms when the
Company's independent existence will be materially altered by a transaction;

               h.  to establish a process designed to obtain the best possible
transaction; to assure that a "level playing field" exists when more than one
bidder for the Company emerges, and not to favor one bidder over another during
the "auction" process unless it is designed to assure and is reasonably related
to achieving the best possible price;

               i.  to act with complete candor in communications with the
shareholders and to ensure that their statements are true and complete in all
material respects and are not materially misleading; and

               j.  to act in accordance with their fundamental duties of care
and loyalty.

          29.  In connection with the conduct described herein, the Individual
Defendants violated their fiduciary duties in the following manner:

                                       7
<PAGE>
 
               a.  in failing to fully inform themselves about alternative
acquisition proposals; and

               b.  by entering into a transaction structured to force Alumax
shareholders to tender their shares by agreeing to an inferior stock for stock
transaction as consideration for the second step of the merger transaction.

          30.  By the acts, transactions and courses of conduct alleged herein,
defendants, individually and as part of a common plan and scheme or in breach of
their fiduciary duties to plaintiff and the other members of the Class, are
attempting unfairly to deprive plaintiff and other members of the Class of the
true value of their investment in Alumax.

          31.  As a result of the actions of defendants, plaintiff and the other
members of the Class have been and will be damaged in that they have not and
will not receive their fair proportion of the value of Alumax's assets and
businesses and will be prevented from obtaining appropriate consideration for
their shares of Alumax's common stock.

          32.  Unless enjoined by this Court, the defendants will continue to
breach their fiduciary duties owed to plaintiff and the other members of the
Class, and may consummate the proposed transaction which will exclude the Class
from its fair proportionate share of Alumax's valuable assets and businesses, in
the unfair manner complained of herein, all to the irreparable harm of the
Class.

          33.  Plaintiff and the Class have no adequate remedy at law.

                                       8
<PAGE>
 
          WHEREFORE, plaintiff demands judgment and preliminary and permanent
relief, including injunctive relief, in his favor and in favor of the Class and
against defendants as follows:

               A.  Declaring this action is properly maintainable as a class
action;

               B.  Declaring and decreeing that the merger agreement was entered
into in breach of the fiduciary duties of the Individual Defendants and is
therefore unlawful and unenforceable;

               C.  Enjoining defendants from proceeding with the merger
agreement;

               D.  Enjoining defendants from consummating the merger, or a
business combination with a third party, unless and until the Company adopts and
implements a procedure or process, such as an auction, to obtain the highest
possible price for the Company;

               E.  Directing the Individual Defendants to exercise their
fiduciary duties to obtain a transaction which is in the best interests of
shareholders until the process for the sale or auction of the Company is
completed and the highest possible price is obtained.

               F.  Enjoining defendants from taking any action which may impede
a full and fair auction and open bidding process for the acquisition of Alumax;

               G.  Rescinding, to the extent already implemented, the merger
agreement or any of the terms thereof;

               H.  Awarding plaintiff and the Class appropriate damages;

                                       9
<PAGE>
 
               I.  Awarding plaintiff the costs and disbursements of this
action, including reasonable attorneys' and experts' fees;

               J.  Granting such other and further relief as this Court may
deem just and proper.

                            CLASS ACTION COMPLAINT
                            ----------------------

          Plaintiff alleges upon information and belief, except for paragraph 1
hereof, which is alleged upon knowledge, as follows:

               1.   Plaintiff has been the owner of the common stock of Alumax
Inc. ("Alumax" or the "Company") since prior to the transaction herein
complained of and continuously to date.

               2.   Alumax is a corporation duly organized and existing under
the laws of the State of Delaware.  The Company is an integrated aluminum
company that produces and sells primary aluminum and semifabricated products
such as sheet, plate, extrusions and foil, and other fabricated products.

               3.   Aluminum Company of America ("Alcoa") is a Delaware
corporation based in Pittsburgh, Pennsylvania and is the world's largest
integrated aluminum concern.

               4.   Defendant Allen Born is Chairman of the Board and Chief
Executive Officer of the Company.
<PAGE>
 
               5.   Defendants are Harold Brown, Pierre Des Marias, II, J.
Dennis Bonney, L. Don Brown, James C. Huntington, Jr., W. Loeber Landau, Allen
Born, Paul V. McAvoy, and Anne Wexler are Directors of Alumax.

               6.   The Individual Defendants are in a fiduciary relationship
with Plaintiff and other public stockholders of Alumax and owe them the highest
obligations of good faith and fair dealing.

                    CLASS ACTION ALLEGATIONS
                    ------------------------

               7.   Plaintiff brings this action on its own behalf and as a
class action, pursuant to Rule 23 of the Rules of the Court of Chancery, on
behalf of all common stockholders of the Company (except the defendants herein
and any person, firm, trust, corporation or other entity related to or
affiliated with any of the defendants) and their successors in interest, who are
or will be threatened with injury arising from defendants' actions as more fully
described herein.

               8.   This action is properly maintainable as a class action
because:

                    (a) The class is so numerous that joinder of all members is
impractical. As of March 31, 1997, there were approximately 54,913,013 shares
of Alumax common stock outstanding owned by hundreds, if not thousands, of
record and beneficial holders;

                    (b) There are questions of law and fact which are common to
the class including, inter alia, the following: (i) whether defendants have
                     ----------
breached their fiduciary and other common law duties owed by them to plaintiff
and the members of the class; and (ii) whether the class is entitled to
injunctive relief or damages as a result of the wrongful conduct committed by
defendants. 

                    (c) Plaintiff is committed to prosecuting this action and
has retained competent counsel experienced in litigation of this nature.  The
claims of the plaintiff are typical of the claims of other members of the class
and plaintiff has the same interests as the other members of the class.
Plaintiff will fairly and adequately represent the class.

                                       2
<PAGE>
 
                    (d) Defendants have acted in a manner which affects
plaintiff and all members of the class alike, thereby making appropriate
injunctive relief and/or corresponding declaratory relief with respect to the
class as a whole.

                    (e) The prosecution of individual actions by individual
members of the Class would create a risk of inconsistent or varying
adjudications with respect to individual members of the Class, which would
establish Incompatible standards of conduct for defendants, or adjudications
with respect to individual members of the Class which would, as a practical
matter, be dispositive of the interests of other members or substantially impair
or impede their ability to protect their interests.

                    SUBSTANTIVE ALLEGATIONS
                    -----------------------

             9.     On March 9, 1998, Alumax and Alcoa announced that they had
entered into a definitive merger agreement whereby Alcoa will acquire Alumax in
a transaction valued at $3.8 billion.  Under the terms of the transaction as
presently proposed, Alcoa will first commence a cash tender offer for one half
of Alumax's outstanding common shares at a price of $50 per share.  The second
step of the proposed transaction will be a merger in which the remaining
outstanding shares of Alumax will each be converted into 0.6975 of a share of
Alcoa common stock, which values them at $49.96 per share based on Alcoa's
closing price of Friday, March 6, 1998.

            10.     The proposed transaction is structured to coerce the
shareholders of Alumax into tendering their shares in the first step of the
proposed transaction, in order to avoid the risk of receiving the lesser and
uncertain consideration offered in the second step merger.

            11.     By entering into the agreement with Alcoa, the Alumax Board
has initiated a process to sell the Company which imposes heightened fiduciary
responsibilities and requires enhanced scrutiny by the Court.  However, the
terms of the proposed transaction were not the result of an auction process or
active market check; they were arrived at without a full and thorough
investigation by the Individual Defendants; and 

                                       3
<PAGE>
 
they are intrinsically unfair and inadequate from the standpoint of the Alumax
shareholders.

            12.     The Individual Defendants failed to make an informed
decision, as no market check of the Company's value was obtained. In agreeing to
the merger, the Individual Defendants failed to properly inform themselves of
Alumax's highest transactional value.

            13.     The Individual Defendants have violated the fiduciary duties
owed to the public shareholders of Alumax.  The Individual Defendants' agreement
to the terms of the transaction, its timing, and the failure to auction the
Company and invite other bidders, and defendants' failure to provide a market
check demonstrate a clear absence of the exercise of due care and of loyalty to
Alumax's public shareholders.

            14.     The Individual Defendants' fiduciary obligations under these
circumstances require them to:

                    (a) Undertake an appropriate evaluation of Alumax's net
worth as a merger/acquisition candidate; and

                    (b) Engage in meaningful auction with third parties in an
attempt to obtain the best value for Alumax's public shareholders.

            15.     The Individual Defendants have breached their fiduciary
duties by reason of the acts and transactions complained of herein, including
their decision to merge with Alcoa without making the requisite effort to obtain
the best offer possible.

            16.     Plaintiff and other members of the Class have been and will
be damaged in that they have not and will not receive their fair proportion of
the value of Alumax's assets and business, and will be prevented from obtaining
fair and adequate consideration for their shares of Alumax common stock.

            17.     The consideration to be paid to class members in the
proposed merger is unfair and inadequate because, among other things:

                    (a) The intrinsic value of Alumax's common stock is
materially in excess of the amount offered for those securities in the merger
giving due consideration to the anticipated 

                                       4
<PAGE>
 
operating results, net asset value, cash flow, and profitability of the Company;

                    (b) The merger price is not the result of an appropriate
consideration of the value of Alumax because the Alumax Board approved the
proposed merger without undertaking steps to accurately ascertain Alumax's value
through open bidding or at least a "market check mechanism"; and

                    (c) By entering into the agreement with Alcoa, the
Individual Defendants have allowed the price of Alumax stock to be capped,
thereby depriving plaintiff and the Class of the opportunity to realize any
increase in the value of Alumax stock.

            18.     By reason of the foregoing, each member of the Class will
suffer irreparable injury and damages absent injunctive relief by this Court.

            19.     Alcoa is named as a defendant in order to permit the Court
to grant complete relief.

            20.     Plaintiff and other members of the Class have no adequate
remedy at law.

          WHEREFORE, plaintiff and members of the Class demand judgment against
defendants as follows:

          a. Declaring that this action is properly maintainable as a class
             action and certifying plaintiff as the representative of the Class;

          b. Preliminarily and permanently enjoining defendants and their
             counsel, agents, employees and all persons acting under, in concert
             with, or for them, from proceeding with, consummating, or closing
             the proposed transaction;

          c. In the event that the proposed transaction is consummated,
             rescinding it and setting it aside, or awarding rescissory damages
             to the Class;

          d. Awarding compensatory damages against defendants, individually and
             severally, in an amount to be determined at trial, together with
             pre-judgment and post-judgment interest at the maximum rate
             allowable by law, arising from the proposed transaction;

                                       5
<PAGE>
 
          e. Awarding plaintiff its costs and disbursements and reasonable
             allowances for fees of plaintiff's counsel and experts and
             reimbursement of expenses; and

          f. Granting plaintiff and the Class such other and further relief as
             the Court may deem just and proper.

                            CLASS ACTION COMPLAINT
                            ----------------------

          Plaintiff, by his attorneys, alleges upon information and belief,
except as to paragraph 1 which plaintiff alleges upon knowledge, as follows:


          1.   Plaintiff is a stockholder of defendant Alumax Inc. ("Alumax" or
the "Company").

          2.   Defendant Alumax is a Delaware corporation, with executive
offices located at 3424 Peachtree Road North East, Atlanta, Georgia.  Alumax is
a holding company with subsidiaries which produce and market T-ingot and a
variety of premium primary products including extrusion billet, slab and foundry
ingot for customers in rolling mills, extrusion plants, 
<PAGE>
 
foundries and remelt operations. As of January 31, 1998, there were over 53
million shares of Alumax stock outstanding.

          3.   Defendant Allen Born is Chairman of the Board, Chief Executive
Officer and a director of Alumax.

          4.   Defendants Paul W. MaCavoy, Harold Brown, L. Don Brown, Pierre
Des Marais II, W. Loeber Landau, Ann Wexler, J. Dennis Bonney and James C.
Huntington, Jr. are Directors of Alumax.

          5.   The individual defendants named above are collectively referred
to herein as the "Individual Defendants."

          6.   The Individual Defendants as directors of Alumax have fiduciary
duties to plaintiff and the other public common stockholders of Alumax and owe
to plaintiff and the other class members the highest obligations of good faith,
loyalty, fair dealing, due care and candor.

                           CLASS ACTION ALLEGATIONS
                           ------------------------

          7.   Plaintiff brings this action on his own behalf and as a class
action, pursuant to Chancery Court Rule 23, on behalf of all common stockholders
of Alumax, or their successors in interest, who are being and will be harmed by
defendants' actions described below (the "Class").  Excluded from the Class are
defendants herein and any person, firm, trust, corporation, or other entity
related to or affiliated with any of defendants.

          8.   This action is properly maintainable as a class action because:

                                       2
<PAGE>
 
          a.        The Class is so numerous that joinder of all members is
impracticable.  There are approximately 9,300 shareholders of record scattered
throughout the United States;

          b.        There are questions of law and fact which are common to the
Class, including:

                    (i)   whether the defendants have breached their fiduciary
duty to maximize shareholder value; and

                    (ii)  whether plaintiffs and the other members of the Class
would be irreparably harmed if the proposed transaction is not enjoined.

          c.        The defendants have acted or refused to act on grounds
generally applicable to the Class, thereby making appropriate final injunctive
relief with respect to the Class as a whole;

          d.        The prosecution of separate actions by individual members of
the Class could create a risk of inconsistent or varying adjudications with
respect to individual members of the Class which would establish incompatible
standards of conduct for defendants or adjudications with respect to individual
members of the Class which would as a practical matter be dispositive of the
interests of the other members not parties to the adjudications; and

          e.        Plaintiff is committed to prosecuting this action and has
retained competent counsel experienced in litigation of this nature.  The claims
of plaintiff are typical of the claims of the other members of the Class, and
plaintiff has the same interests as the other 

                                       3
<PAGE>
 
members of the Class. Accordingly, plaintiff is an adequate representative of
the Class and will fairly and adequately protect the interests of the Class.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------

          9.   On March 9, 1998, it was announced that Alumax had entered into
an agreement to be acquired by Aluminum Company of America ("Alcoa") in a cash
and stock transaction valued at $3.8 billion.  The transaction will begin with a
$50 per share cash tender offer for one-half of Alumax's shares.  In the second
step of the transaction, each of the remaining Alumax shares will be converted
into .6975 shares of Alcoa.  The tender offer is set to commence on Friday,
March 13, 1998.  The Individual Defendants were required to engage in a process
designed to maximize shareholder value and obtain the best transaction
reasonably available for the Alumax shareholders.

          10.  The Individual Defendants failed to (1) undertake an adequate
evaluation of Alumax's worth as a potential merger/acquisition candidate; (2)
take adequate steps to enhance Alumax's value and/or attractiveness as a
merger/acquisition candidate; or (3) effectively expose Alumax to the
marketplace in an effort to create an active and open auction for Alumax.
Instead, defendants have agreed to a sale of Alumax to Alcoa pursuant to a
transaction which will impede maximization of shareholder value.

          11.  While the Individual Defendants should continue to seek out other
possible purchasers of Alumax in a manner designed to obtain the best
transaction reasonably available for Alumax's shareholders, or seek to enhance
the value of Alumax for all its current 

                                       4
<PAGE>
 
shareholders, they have instead resolved wrongfully to allow Alcoa to obtain the
valuable assets of Alumax at an inadequate price which disproportionately
benefits Alcoa.

          12.  As a result of the Individual Defendants' wrongful actions,
plaintiff and the other members of the Class will be irreparably harmed and
prevented from obtaining the maximum value for their shares.  Unless the
proposed transaction is enjoined, the Individual Defendants will continue to
breach their fiduciary duties owed to plaintiff and the members of the Class,
and will consummate the proposed transaction to the irreparable harm of the
members of the Class.

          13.  Plaintiff and the other members of the Class have no adequate
remedy at law.

          WHEREFORE, plaintiff prays for judgment and relief as follows:

          A.   Ordering that this action may be maintained as a class action and
certifying plaintiff as the Class representative;

          B.   Preliminarily and permanently enjoining the proposed transaction
until defendants have fulfilled their duty to engage in a process to maximize
shareholder value;

          C.   If the proposed transaction is consummated, rescinding it and
setting it aside;

          D.   Awarding damages against defendants together with pre-judgment
and post-judgment interest;

                                       5
<PAGE>
 
          E.   Awarding costs and disbursements, including attorneys' fees and
experts' fees; and

          F.   Granting such other and further relief as to the Court may deem
just and proper.
