                          KAISER ALUMINUM CORPORATION

                          CONVERTIBLE PREFERRED STOCK
                            ------------------------
   
    Kaiser Aluminum Corporation, a Delaware corporation (the "Company"), is
hereby offering for sale 8,000,000 shares of Preferred Redeemable Increased
Dividend Equity SecuritiesSM,     % PRIDESSM, Convertible Preferred Stock, par
value $.05 per share (the "PRIDES").
    
 
    The annual dividend payable with respect to each share of PRIDES is $    .
Dividends will be cumulative from the date of issuance and will be payable
quarterly in arrears on the last day of each March, June, September and December
of each year, commencing March 31, 1994. The liquidation preference applicable
to each share of PRIDES is equal to the sum of (i) the per share price to the
public shown below, and (ii) the amount of accrued and unpaid dividends thereon.
 
   
    On December 31, 1997 (the "Mandatory Conversion Date"), unless either
previously redeemed or converted at the option of the holder, each of the
outstanding shares of PRIDES will mandatorily convert into (i) one share of the
Company's common stock, par value $.01 per share (the "Common Stock"), subject
to adjustment in certain events and (ii) the right to receive an amount in cash
equal to all accrued and unpaid dividends thereon.
    
 
    Shares of PRIDES are not redeemable prior to December 31, 1996. At any time
and from time to time on or after December 31, 1996, until immediately prior to
the Mandatory Conversion Date, the Company may redeem any or all of the
outstanding shares of PRIDES. Upon any such redemption, each holder will
receive, in exchange for each share of PRIDES, the number of shares of Common
Stock equal to (A) the sum of (i) $      , declining after December 31, 1996, as
set forth herein to $      until the Mandatory Conversion Date, plus, in the
event the Company does not elect to pay cash dividends to the redemption date,
(ii) all accrued and unpaid dividends thereon (the "Call Price") divided by (B)
the Current Market Price (as defined herein) on the applicable date of
determination, but in no event less than     of a share of Common Stock, subject
to adjustment in certain events.
 
    At any time prior to the Mandatory Conversion Date, unless previously
redeemed, each share of PRIDES is convertible at the option of the holder
thereof into     of a share of Common Stock (equivalent to a conversion price of
$    per share of Common Stock (the "Conversion Price")), subject to adjustment
in certain events. The number of shares of Common Stock a holder will receive
upon redemption, and the value of the shares received upon conversion, will vary
depending on the market price of the Common Stock from time to time, all as set
forth herein.
 
   
    The opportunity for equity appreciation afforded by an investment in the
shares of PRIDES is less than that afforded by an investment in the Common Stock
because the Conversion Price is higher than the per share price to the public of
the shares of PRIDES, and the Company may, at its option, redeem the shares of
PRIDES at any time on or after December 31, 1996, and prior to the Mandatory
Conversion Date, and may be expected to do so if, among other circumstances, the
Current Market Price of the Common Stock exceeds the Call Price. In such event,
a holder of a share of PRIDES will receive less than one share of Common Stock,
but no less than     of a share of Common Stock. The value per share of PRIDES
of the Common Stock received by holders of PRIDES may be more or less than the
per share amount paid for the PRIDES offered hereby, due to market fluctuations
in the price of the Common Stock. For a detailed description of the terms of the
PRIDES, see "Description of PRIDES." The Company does not currently pay
dividends on its Common Stock. Annual dividends per share of Common Stock may be
increased or decreased at the discretion of the Board of Directors of the
Company (except that the New Credit Agreement (as defined) will prohibit the
Company from paying dividends on its Common Stock). See "Dividend Policy."
    
 
   
    The shares of PRIDES and the Common Stock issuable in respect thereof have
been approved for listing on the New York Stock Exchange (the "NYSE"), subject
to official notice of issuance. The shares of PRIDES will be listed on the NYSE
under the symbol "KLUPrD." The Company's Common Stock is listed on the NYSE
under the symbol "KLU." The closing sale price of the Common Stock on the NYSE
on February 7, 1994, was $11 1/2 per share.
    
 
   
    In connection with the offering of shares of PRIDES hereby, Kaiser Aluminum
& Chemical Corporation, a Delaware corporation and a wholly owned subsidiary of
the Company ("KACC"), is concurrently offering, pursuant to a separate
prospectus, $175.0 million aggregate principal amount of its Senior Notes (as
defined). For a detailed description of the terms of the Senior Notes, see
"Description of Principal Indebtedness." KACC is also replacing its existing
Credit Agreement (as defined) with a new five year, secured revolving line of
credit in the amount of $250.0 million (the "New Credit Agreement"). The
offering of the shares of PRIDES, the offering of the Senior Notes and the
effectiveness of the New Credit Agreement will be conditioned upon the
simultaneous closing of all such transactions.
    
 
    SEE "RISK FACTORS" FOR A DISCUSSION OF CERTAIN FACTORS THAT SHOULD BE
CONSIDERED IN CONNECTION WITH AN INVESTMENT IN THE PRIDES OFFERED HEREBY.

                                  THE COMPANY
 
     Kaiser Aluminum Corporation, a Delaware corporation (the "Company"), is one
of the world's leading producers of alumina, primary aluminum and fabricated
(including semi-fabricated) aluminum products. The Company, through its wholly
owned subsidiary, Kaiser Aluminum & Chemical Corporation, a Delaware corporation
("KACC"), operates in all principal aspects of the aluminum industry -- the
mining of bauxite, the refining of bauxite into alumina, the production of
primary aluminum and the manufacture of fabricated aluminum products. In 1993,
the Company produced 2,826,600 tons of alumina, of which approximately 71% was
sold to third parties, produced 436,200 tons of primary aluminum, of which
approximately 56% was sold to third parties, and shipped approximately 373,200
tons of fabricated aluminum products to third parties, which accounted for
approximately 6% of the total tonnage of United States domestic fabricated
aluminum products shipments in 1993. The Company's share of total Western world
alumina capacity and total Western world primary aluminum capacity was 8% and
3%, respectively, in 1993.
 
     The Company's strategy is to enhance its position as a leading producer of
alumina, primary aluminum and fabricated aluminum products by:
 
   
     Increasing alumina production capacity. The Company has increased the
capacity of its 65%-owned Alumina Partners of Jamaica ("Alpart") alumina
refinery from 1,000,000 tons per year as of December 31, 1990, to 1,450,000 tons
per year as of December 31, 1992. In addition, during the past several years the
Company has increased production at its Gramercy, Louisiana alumina refinery and
its 28.3%-owned Queensland Alumina Limited ("QAL") alumina refinery located in
Australia. The percentage of the Company's alumina production sold to third
parties increased to approximately 71% in 1993 from approximately 35% in 1987.
Among alumina producers, the Company believes it is now the world's second
largest seller of alumina to third parties. In light of the previously
announced, and possible future, curtailments or permanent shutdowns of
world-wide primary aluminum production, the Company anticipates that its alumina
production and alumina sales to third parties will decline in 1994 from 1993
levels. See "-- Recent Trends and Developments."
    
 
   
     Improving the efficiency of its operations. From 1980 to 1993, on a per
employee basis, alumina production increased by approximately 54% at the
Company's Gramercy, Louisiana alumina refinery; fabricated products shipments
increased by approximately 128% at the Company's Trentwood, Washington
fabricating facility; and sales volume for aluminum operations as a whole
increased by over 250%. Primary aluminum production at the Company's Mead and
Tacoma smelters was curtailed in 1993 because of a power reduction imposed by
the Bonneville Power Administration ("BPA") which reduced the operating rates
for such smelters. From 1980 to 1992, prior to the BPA power reductions, on a
per employee basis, primary aluminum production increased by approximately 72%
and 39%, respectively, at the Mead and Tacoma smelters, and from 1980 to 1993,
subsequent to the BPA power reductions, such primary aluminum production
increased by approximately 36% and 15%, respectively, at such smelters. See
"Risk Factors -- Recent Developments in Power Supply for Pacific Northwest
Operations and Resultant Production Curtailments." The Company has also
streamlined and decentralized its management structure to reduce corporate
overhead and shift decision-making and accountability to its business units.
KACC announced in October 1993 that it is restructuring its flat-rolled products
operation at its Trentwood plant in the state of Washington, which is expected
to result in annual cost savings of approximately $50.0 million after the
restructuring has been fully implemented. See "-- Recent Trends and
Developments."
    
 
     The Company has developed and installed proprietary retrofit technology in
all of its smelters, which has contributed to increased and more efficient
production of primary aluminum. The Company is actively
 
                                        3

<PAGE>   6
 
engaged in efforts to license this technology and sell technical and managerial
assistance to other producers worldwide, and may participate in joint ventures
or similar business partnerships which employ the Company's technical and
managerial knowledge. Through continuing technological improvements, the
Company's smelters have achieved improved energy efficiency and longer average
life of reduction cells. From 1980 to 1993, the Company's average kilowatt hours
of electricity utilized per ton of primary aluminum production was reduced by
approximately 13% and the average life of reduction cells was increased by
approximately 102%.
 
     Concentrating its fabricated aluminum products operations on the beverage
container market and on high value-added transportation products. The Company
operates a high-speed, wide-coil coating line which has reduced costs, improved
quality and increased sales of aluminum to the beverage container industry. The
Company believes that it is one of the highest quality producers of aluminum
beverage can stock in the world. Over the past several years, the Company has
also constructed four new fabrication facilities and modernized and expanded
others to produce high value-added automotive (including air bag cannisters),
truck (including truck wheels and hubs), trailer and aerospace products.
 
   
     Implementing a refinancing plan. The offering of PRIDES, the concurrent
offering by KACC of $175.0 million aggregate principal amount of its      %
Senior Notes due 2002 (the "Senior Notes"), and the replacement of KACC's
existing Credit Agreement (the "Credit Agreement") are the final steps of a
comprehensive refinancing plan which the Company began in January 1993. The plan
is intended to extend the maturities of the Company's outstanding indebtedness,
to enhance its liquidity and to raise new equity capital.
    
 
   
     As of December 31, 1992, the Company's long-term indebtedness consisted
principally of $321.7 million aggregate amount of KACC's 14 1/4% Senior
Subordinated Notes due 1995 (the "14 1/4% Notes"), and the Credit Agreement,
which matures in November 1994. KACC refinanced the 14 1/4% Notes through the
issuance in February 1993 of $400.0 million aggregate principal amount of its
12 3/4% Senior Subordinated Notes due 2003 (the "12 3/4% Notes"). In addition,
KACC has received a commitment (the "Commitment Letter") to replace the Credit
Agreement ($225.0 million outstanding as of February 4, 1994) with a $250.0
million secured, revolving line of credit, scheduled to mature in 1999 (the "New
Credit Agreement"). Bank of America National Trust and Savings Association
("Bank of America") and BankAmerica Business Credit, Inc. ("BA") have committed,
subject to certain terms and conditions, to provide the full $250.0 million of
the New Credit Agreement.
    
 
   
     As of December 31, 1993, the Company's total consolidated indebtedness was
$729.4 million, and $113.6 million of borrowing capacity was unused under the
revolving credit facility of the Credit Agreement. On a pro forma basis, after
giving effect to the sale of the PRIDES, the sale of the Senior Notes and the
effectiveness of the New Credit Agreement (collectively, the "Refinancing
Transactions"), as of December 31, 1993, the Company's total consolidated
indebtedness would have been $715.9 million, $182.5 million of borrowing
capacity would have been available for use under the New Credit Agreement and
the Company would have had additional cash available of $48.7 million. See
"Capitalization." The foregoing does not give effect to $73.6 million of
guaranteed unconsolidated joint venture indebtedness of the Company and $37.6
million of other guarantees and letters of credit outstanding as of December 31,
1993.
    
 
   
     To increase its equity capital, the Company consummated a public offering
of its $.65 Depositary Shares in June 1993 pursuant to which the Company
realized net proceeds of approximately $119.3 million. The Company will realize
additional net proceeds of approximately $79.9 million as a result of the sale
of the PRIDES. See "Use of Proceeds."
    
 
   
     After giving effect to the Refinancing Transactions, the scheduled
amortization of the Company's long-term indebtedness through 1998 will be
substantially reduced and the Company expects that it will be able to satisfy
its debt service and capital expenditure requirements through at least December
31, 1995, from cash flows generated by operations and, to the extent necessary,
from borrowings under the New Credit Agreement. See "Capitalization" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Financial Condition and Capital Spending."

                         RECENT TRENDS AND DEVELOPMENTS
 
     Exports from the Commonwealth of Independent States, additions to smelter
capacities during the past several years, continued high operating rates and
other factors have contributed to a significant increase in primary aluminum
inventories in the Western world. If Western world production and exports from
the Commonwealth of Independent States continue at current levels, primary
aluminum inventory levels will increase further in 1994. The foregoing factors,
among others, have contributed to a significant reduction in the market price of
primary aluminum, and may continue to adversely affect the market price of
primary aluminum in the future.
 
   
     Government officials from the European Union, the United States of America,
Canada, Norway, Australia and the Russian Federation met in a multilateral
conference in January 1994, to discuss the current excess global supply of
primary aluminum. All six participating governments have ratified as a trade
agreement the resulting Memorandum of Understanding (the "Memorandum") which
provides, in part, for (i) a reduction in Russian Federation primary aluminum
production by 300,000 tons per year within three months of the date of
ratification of the Memorandum and an additional 200,000 tons within the
following three months, (ii) improved availability of comprehensive data on
Russian aluminum production and (iii) certain assistance to the Russian aluminum
industry. A Russian Federation Trade Ministry official has publicly stated that
the output reduction would remain in effect for 18 months to two years, provided
that other worldwide production cutbacks occur, existing trade restrictions on
aluminum are eliminated and no new trade restrictions on aluminum are imposed.
The Memorandum does not require specific levels of production cutbacks by other
producing nations. A further meeting of the participants is scheduled for the
end of February 1994. There can be no assurance that the implementation of the
Memorandum will adequately address the current oversupply of primary aluminum.
See "-- Sensitivity to Prices and Hedging Programs -- Alumina and Primary
Aluminum." The Company will continue to assess its production levels in light of
market prices, industry inventory levels, production costs and user demand and,
based on these and other factors, could determine to curtail production at
certain of its facilities in the future.
    
 
   
     If the Company's average realized sales prices in 1994 for substantial
quantities of its primary aluminum and alumina were based on the current market
price of primary aluminum (the average Midwest U.S. transaction price ("AMT
Price") was 61.14c per pound for the week ended February 4, 1994 -- See
"Business -- Sensitivity to Prices"), the Company would continue to sustain net
losses in 1994, which would be expected to approximate the loss in 1993 ($81.5
million) before (a) extraordinary loss and cumulative effect of changes in
accounting principles, (b) the charges related to the restructuring of the
Trentwood plant and certain other facilities (the "1993 Facilities Charges") and
(c) certain other charges principally related to a reduction in the carrying
value of the Company's inventories ($19.4 million, which is included in cost of
goods sold) and the establishment of additional litigation and environmental
reserves (the "Other 1993 Charges"). See "Management's Discussion and Analysis
of Financial Condition and Results of Operations," "Business -- Industry
Overview -- Recent Industry Trends" and "Business -- Sensitivity to Prices and
Hedging Programs -- Alumina and Primary Aluminum."
    
 
     KACC announced in October 1993 that it is restructuring its flat-rolled
products operation at its Trentwood plant in the state of Washington, to reduce
that facility's annual operating costs. This effort is in response to
over-capacity in the aluminum rolling industry, flat demand in can stock
markets, and declining demand for aluminum products sold to customers in the
commercial aerospace industry, all of which have resulted in declining prices in
Trentwood's key markets. The Trentwood restructuring is expected to result in
annual cost savings of approximately $50.0 million after it has been fully
implemented (which is expected to occur during the next two years). See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," and "Business -- Product Operations -- Fabricated Products."
 
                      FOURTH QUARTER AND YEAR END RESULTS
 
     The Company's net sales totaled $415.9 million in the fourth quarter of
1993, compared with $496.0 million in the fourth quarter of 1992 and $1,719.1
million for the full year of 1993, compared with $1,909.1 million for the full
year of 1992. Revenues decreased in the fourth quarter of 1993 as compared to
the
 
                                        5

<PAGE>   8
 
fourth quarter of 1992 due principally to lower average realized prices and
shipments of primary aluminum and alumina and lower average realized prices of
most fabricated products, partially offset by increased shipments of fabricated
products during the 1993 period compared with the 1992 period. Revenues
decreased for the full year of 1993 as compared to the full year of 1992 due
principally to lower shipments of primary aluminum and lower average realized
prices of primary aluminum and alumina and, to a lesser extent, of fabricated
products, partially offset by increased shipments of most fabricated products
during 1993 as compared to 1992.
 
     The Company will report a net loss before extraordinary loss and cumulative
effect of changes in accounting principles of $123.1 million (including the 1993
Facilities Charges and the Other 1993 Charges) for the full year of 1993,
compared with net income of $26.9 million for the full year of 1992. The Company
will report a net loss of $66.1 million (including the 1993 Facilities Charges
and the Other 1993 Charges) for the fourth quarter of 1993, compared with net
income of $2.6 million for the fourth quarter of 1992. The Company recognized an
after-tax loss relating to the cumulative effect of changes in accounting
principles of $507.3 million and an after-tax extraordinary loss on early
extinguishment of debt of $21.8 million in the first quarter of 1993. See Note
(1) of "Summary Historical and Pro Forma Consolidated Financial Data."
 
     The fourth quarter results include a pre-tax charge of $35.8 million ($22.6
million after-tax) related to the 1993 Facilities Charges and pre-tax charges of
$30.2 million ($19.0 million after-tax) principally related to the Other 1993
Charges. The Company will also recognize an after-tax reduction of stockholders'
equity of $14.9 million in the fourth quarter of 1993 to reflect the lowering of
the discount rate used to calculate the Company's minimum pension liability. The
Company recognized a pre-tax charge of $29.0 million ($24.2 million after-tax)
related to a reduction in the carrying value of the Company's inventory, pre-tax
income of $14.0 million ($11.7 million after-tax) for non-recurring adjustments
to previously recorded liabilities and reserves and an after-tax reduction of
stockholders' equity of $6.7 million in the fourth quarter of 1992.

                             PRIDES -- Dividends."
    
 
   
                             The Company expects to make dividend payments on
                             the shares of PRIDES until the Mandatory Conversion
                             Date out of funds provided to it by KACC pursuant
                             to the terms of the Intercompany Note (as defined
                             in "Use of Proceeds"). The declaration and payment
                             of dividends by the Company on the shares of PRIDES
                             will be expressly permitted by the terms of the New
                             Credit Agreement to the extent the Company receives
                             payments on the Intercompany Note. Payments on the
                             Intercompany Note will be expressly subordinated in
                             right of payment to the extent set forth therein to
                             the prior payment in full of all monetary
                             obligations of KACC under the New Credit Agreement,
                             including certain refundings, refinancings,
                             replacements or restructurings of such monetary
                             obligations, and to the payment of principal,
                             premium, if any, and interest on the Senior Notes.
                             In the event of a KACC Merger (as defined below
                             under "Voting Rights"), the Intercompany Note will
                             be terminated by operation of law and the payment
                             of dividends on the shares of PRIDES will be
                             subject to the restrictions relating to the
                             declaration and payment of dividends on the capital
                             stock of the surviving entity set forth in the
                             12 3/4% Note Indenture (as defined) and any other
                             agreements then in effect governing indebtedness of
                             the surviving entity. See "Risk
                             Factors -- Restrictions on Ability to Pay
                             Dividends."
    
 
MANDATORY CONVERSION         On the Mandatory Conversion Date, unless previously
                             redeemed or converted, each outstanding share of
                             PRIDES will mandatorily convert into (i) one share
                             of Common Stock, subject to adjustment in certain
                             events, and (ii) the right to receive cash in an
                             amount equal to all accrued and unpaid dividends
                             thereon (other than previously declared dividends
                             payable to a holder of record on a prior date). See
                             "Description of PRIDES -- Mandatory Conversion of
                             PRIDES." The value per share of PRIDES of the
                             Common Stock that may be received by holders of
                             PRIDES upon their mandatory conversion may be more
                             or less than the amount paid for the PRIDES offered
                             hereby due to market fluctuations in the price of
                             the Common Stock.
OPTIONAL REDEMPTION........  Shares of PRIDES are not redeemable prior to
                             December 31, 1996. At any time and from time to
                             time on or after December 31, 1996 until
                             immediately prior to the Mandatory Conversion Date,
                             the Company may redeem any or all of the
                             outstanding shares of PRIDES. Upon any such
                             redemption, each holder will receive, in exchange
                             for each share of PRIDES, a number of shares of
                             Common Stock equal to the sum of (i) $     ,
                             declining after December 31, 1996 as set forth
                             herein to $     until the Mandatory Conversion
                             Date, and (ii) all accrued and unpaid dividends
                             thereon (other than previously declared dividends
                             payable to a holder of record as of a prior date)
                             (the "Call Price") divided by the Current Market
                             Price (as defined) on the applicable date of
                             determination, but in no event less than      of a
                             share of Common Stock, subject to adjustment as
                             described herein. See "Description of
                             PRIDES -- Optional Redemption." The number of
                             shares of Common Stock to be delivered based on the
                             applicable Call Price will be determined on the
                             basis of the Current Market Price of the Common

                             Stock prior to the announcement of the redemption,
                             and the market price of the Common Stock may vary
                             between the date of such determination and the
                             subsequent delivery of such shares.
 
CONVERSION AT THE OPTION OF
  THE HOLDER...............  At any time prior to the Mandatory Conversion Date,
                             unless previously redeemed, each share of PRIDES is
                             convertible at the option of the holder thereof
                             into      of a share of Common Stock, equivalent to
                             a conversion price of $       per share of Common
                             Stock (the "Conversion Price"), subject to
                             adjustment as described herein. The value of the
                             shares of Common Stock received upon conversion
                             will vary depending on the market price of the
                             Common Stock from time to time, all as set forth
                             herein. The right of holders to convert shares of
                             PRIDES called for redemption will terminate
                             immediately prior to the close of business on the
                             day prior to the redemption date. See "Description
                             of PRIDES -- Conversion at the Option of the
                             Holder."
 
ENHANCED DIVIDEND YIELD;
LESS EQUITY APPRECIATION
  THAN COMMON STOCK........  Dividends will accrue on the PRIDES at a higher
                             rate than the rate at which dividends are currently
                             paid on the Common Stock. No dividends are
                             currently paid on the Common Stock. The owners of
                             shares of PRIDES are entitled to receive (when, as
                             and if the Board of Directors declares dividends)
                             cumulative preferential cash dividends from the
                             date of issue accruing at the rate of $.   per
                             annum or $.   per quarter for each share of PRIDES.
                             See "Description of the PRIDES -- Dividends."
 
                             The opportunity for equity appreciation afforded by
                             an investment in the PRIDES is less than that
                             afforded by an investment in the Common Stock
                             because the Conversion Price is higher than the per
                             share price to the public of the shares of PRIDES
                             and the Company may, at its option, redeem the
                             shares of PRIDES at any time on or after December
                             31, 1996 and prior to the Mandatory Conversion
                             Date, and may be expected to do so if, among other
                             circumstances, the Current Market Price of the
                             Common Stock exceeds the Call Price. In such event,
                             a holder of a share of PRIDES will receive less
                             than one share of Common Stock, but no less than
                                  of a share of Common Stock. A holder may also
                             surrender for conversion any PRIDES called for
                             redemption up to the close of business on the day
                             prior to the redemption date, and a holder that so
                             elects to convert will receive        of a share of
                             Common Stock per share of PRIDES. The value per
                             share of PRIDES of the Common Stock received by
                             holders of PRIDES may be more or less than the per
                             share amount paid for the PRIDES offered hereby,
                             due to market fluctuations in the price of Common
                             Stock. See "Description of PRIDES -- Enhanced
                             Dividend Yield; Less Equity Appreciation than
                             Common Stock."
 
VOTING RIGHTS..............  Holders of shares of PRIDES will have 4/5 vote for
                             each share held of record and, except as required
                             by law, will be entitled to vote together with the
                             holders of Common Stock and together with the
                             holders of any other classes or series of stock
                             (including the Series A Shares) who are entitled to
                             vote in such manner on all matters submitted to a
                             vote of common stockholders. In addition, subject
                             to certain exceptions, the affirmative vote of
                             two-thirds of the shares of PRIDES actually voting
                             (voting separately as a class) will be required to
                             permit the Company to

                             security convertible at the option of the holder
                             thereof into shares of any class or series of
                             stock, ranking senior to the PRIDES as to dividends
                             or upon Liquidation, (ii) modify the terms of the
                             Intercompany Note in a manner that materially
                             adversely affects the Company as the holder of such
                             Intercompany Note or the holders of the PRIDES,
                             (iii) amend the Certificate of Incorporation in a
                             manner that materially adversely affects the
                             holders of the PRIDES, (iv) consummate a merger or
                             consolidation of the Company with KACC (a "KACC
                             Merger") if (a) each outstanding share of PRIDES,
                             upon the effectiveness of the KACC Merger, neither
                             remains outstanding nor is converted into one share
                             of preferred stock of the surviving corporation
                             ("KACC Preferred Stock"), (b) such shares of KACC
                             Preferred Stock (if issued in the KACC Merger) are
                             not to be deposited with a bank or trust company
                             upon or prior to the effectiveness of the KACC
                             Merger, or (c) the covenants in the debt
                             instruments of the surviving corporation of the
                             KACC Merger, at the time of the KACC Merger,
                             prohibit the payment of any of the dividends on the
                             PRIDES or the KACC Preferred Stock, as the case may
                             be, in accordance with the terms thereof through
                             and including the day immediately prior to the
                             Mandatory Conversion Date, or (v) consummate a
                             merger or consolidation of the Company with any
                             other corporation, unless each holder of shares of
                             PRIDES immediately preceding such merger or
                             consolidation receives or continues to hold in the
                             surviving corporation the same number of shares,
                             with, subject to certain exceptions, substantially
                             the same rights and preferences, as correspond to
                             the shares of PRIDES so held. In the event that
                             dividends payable on the PRIDES or any other series
                             of preferred stock are in arrears in an aggregate
                             amount equivalent to six full quarterly dividend
                             periods, and in certain other circumstances, the
                             holders of the outstanding PRIDES will be entitled
                             to elect, together with the holders of all other
                             series of outstanding preferred stock as to which
                             voting rights are exercisable, voting separately as
                             a class, two directors of the Company. See
                             "Description of PRIDES -- Voting Rights."
 
   
LIQUIDATION PREFERENCE.....  The PRIDES are shares of convertible preferred
                             stock and rank (i) senior in right and priority of
                             payment to the Common Stock upon liquidation and
                             (ii) on a parity with the Series A Shares upon
                             liquidation. Subject to the terms of any stock
                             ranking senior to, or on a parity with, the shares
                             of PRIDES, the liquidation preference applicable to
                             each share of PRIDES will be an amount equal to the
                             sum of (i) the price to public for each share of
                             PRIDES shown on the cover page of this Prospectus
                             and (ii) an amount equal to all accrued and unpaid
                             dividends payable with respect to such share of
                             PRIDES. See "Description of PRIDES -- Liquidation
                             Rights."

(1) Includes extraordinary loss on early extinguishment of debt of $21.8, net of
    tax benefit of $11.2, and cumulative effect of changes in accounting
    principles of $507.3, net of tax benefit of $237.7. See "Management's
    Discussion and Analysis of Financial Condition and Results of Operations --
    Results of Operations."
(2) Based upon the weighted average number of common and common equivalent
    shares outstanding during each period.
(3) For the nine months ended September 30, 1993, common stock equivalents of
    19,382,950 attributable to the Series A Shares were excluded from the
    calculation of weighted average shares because they were antidilutive.
    Dividends on the Series A Shares of $3.2 are added to the net loss for the
    purpose of calculating earnings per share.
(4) For the purpose of calculating the ratio of earnings to combined fixed
    charges and preferred stock dividends, "earnings" consist of the sum of (i)
    income (loss) before extraordinary loss and cumulative effect of changes in
    accounting principles of the Company and its consolidated subsidiaries, (ii)
    undistributed (earnings) losses of less-than-fifty-percent-owned companies,
    (iii) minority interest share of income (losses) of majority-owned
    subsidiaries that have fixed charges, (iv) consolidated provision for income
    taxes, (v) minority interest share of tax provision (credit) of
    majority-owned subsidiaries that have fixed charges, (vi) fixed charges,
    (vii) equity in losses of less-than-fifty-percent-owned companies where the
    Company has guaranteed the debt of such companies, and (viii) previously
    capitalized interest amortized during the period. Fixed charges consist of
    the sum of interest expense, amortization of deferred financing costs, the
    portion of rents representative of the interest factor, preferred stock
    dividend requirements and interest expense related to the guaranteed debt of
    less-than-fifty-percent-owned companies incurring a loss.
(5) For the nine months ended September 30, 1993, earnings were inadequate to
    cover combined fixed charges and preferred stock dividends by $98.4.
   
(6) The pro forma information assumes (a) the issuance and sale of 8,000,000
    shares of PRIDES, (b) a capital contribution by the Company to KACC in the
    amount of $52.5, (c) a non-interest bearing loan from the Company to KACC in
    the principal amount of $27.4 evidenced by the Intercompany Note, (d) the
    sale by KACC of $175.0 aggregate principal amount of Senior Notes and (e)
    the effectiveness of the New Credit Agreement (collectively, the "Pro Forma
    Adjustments"), as if such Pro Forma Adjustments had occurred at the
    beginning of the respective periods for operating data and on September 30,
    1993, for the balance sheet data.
    
(7) Includes a pro forma extraordinary loss of $15.2 and $20.1 for the nine
    months ended September 30, 1993, and the year ended December 31, 1992,
    respectively, representing the deferred financing costs written off upon the
    refinancing of the Credit Agreement.

                                  RISK FACTORS
 
     Prospective investors should carefully consider the factors set forth below
as well as the other information contained in this Prospectus.
 
RESTRICTIONS ON AND FACTORS AFFECTING ABILITY TO PAY DIVIDENDS;
SUBORDINATION OF INTERCOMPANY NOTE; TERMINATION OF INTERCOMPANY NOTE
 
     Source of Dividend Payments.  The Company conducts all of its operations
through KACC. The Company expects to make dividend payments on the shares of
PRIDES until the Mandatory Conversion Date out of funds provided to it by KACC
pursuant to the terms of the Intercompany Note. The declaration and payment of
dividends by the Company on the shares of PRIDES will be expressly permitted by
the terms of the New Credit Agreement to the extent the Company receives
payments on the Intercompany Note. The Intercompany Note is designed to provide
sufficient funds to the Company to enable it to make dividend payments on the
shares of PRIDES until the Mandatory Conversion Date. The Intercompany Note will
mature on December 31, 1997, and will be payable in quarterly installments.
 
   
     Subordination of Intercompany Note.  Payments on the Intercompany Note will
be expressly subordinated in right of payment to the extent set forth therein to
the prior payment in full of (i) all monetary obligations of KACC under the New
Credit Agreement, including certain refundings, refinancings, replacements or
restructurings of such monetary obligations, and (ii) the principal of, premium,
if any, and interest on the Senior Note Indenture. As a result, in the event of
a dissolution, liquidation or reorganization of KACC, the right of the Company
to realize upon the assets of KACC, as a creditor of KACC pursuant to the
Intercompany Note, will be subject to the prior claims of the financial
institutions party to New Credit Agreement and the holders of the Senior Notes,
and no payments will be made with respect to the Intercompany Note (or
distributions made in respect of the shares of PRIDES under such circumstances),
unless and until such prior claims have been satisfied in full in cash (KACC's
obligations under the Intercompany Note, however, will not be subordinated to
KACC's obligations in respect of the 12 3/4% Notes and will rank pari passu in
right and priority of payment with KACC's obligations under the intercompany
note issued in connection with the June 1993 offering of $.65 Depositary
Shares). The Intercompany Note will provide that (i) in the event of a payment
default by KACC under the terms of the New Credit Agreement or the Senior Note
Indenture, no payments on the Intercompany Note to the Company will be permitted
until such payment default shall have been cured or waived and (ii) during the
continuance of other defaults under the New Credit Agreement, no payments on the
Intercompany Note to the Company will be permitted for a period commencing on
the date of receipt by the Company of notice of such default from the agent bank
under the New Credit Agreement, and ending not more than 179 days thereafter;
provided, however, that no payments or distributions will be prohibited by the
provisions referred to in this sentence if (1) any of the 12 3/4% Notes are then
outstanding and (2) payments and distributions on the 12 3/4% Notes are not then
prohibited under certain provisions contained in the 12 3/4% Note Indenture
relating to defaults on Senior Indebtedness (as defined). To the extent that the
Company is dependent upon payments from KACC under the Intercompany Note to
provide it with funds to make dividend payments on the shares of PRIDES, the
    
 
                                       12

<PAGE>   15
 
Company will not have sufficient funds available to make such dividend payments
in the event KACC is prevented from making payments in respect of the
Intercompany Note.
 
     Termination of Intercompany Note. In the event of a merger of the Company
and KACC in accordance with the terms of the shares of PRIDES (see "Description
of the PRIDES -- Voting Rights"), the Intercompany Note will be terminated by
operation of law and the payment of dividends on the shares of PRIDES will be
subject to the restrictions relating to the declaration and payment of dividends
on the capital stock of the surviving entity set forth in the 12 3/4% Note
Indenture and any other agreements then in effect governing indebtedness of the
surviving entity (including the Senior Note Indenture).
 
   
     Recent Dividend Payment History.  The Company paid a quarterly dividend of
$.05 per share of Common Stock, commencing with its initial public offering
during the third quarter of 1991 and continuing through the fourth quarter of
1992. The Company's Board of Directors determined not to declare any dividends
on the Common Stock in 1993. KACC is currently paying dividends in the aggregate
amount of approximately $1.5 million per year in respect of certain series of
its outstanding preference stock. On September 30, 1993, and December 31, 1993,
the Company paid a dividend in the amount of $.1625 per $.65 Depositary Share to
all holders of its outstanding $.65 Depositary Shares. The New Credit Agreement
will not permit the Company or KACC to pay any dividends on their common stock.
The declaration and payment of dividends by KACC on its shares of common stock
will be subject to certain covenants in the Senior Note Indenture and the
12 3/4% Note Indenture. See "Description of Principal Indebtedness."
    
 
FACTORS AFFECTING LIQUIDITY; FAILURE OF EARNINGS TO COVER FIXED CHARGES;
ANTICIPATED 1994 NET LOSS
 
   
     Borrowing Capacity and Refinancing Plans.  The ability of the Company and
its subsidiaries to satisfy their debt service and capital expenditure
requirements will depend upon available cash resources and results of
operations, and, in the case of dividend payments on the shares of PRIDES, the
receipt of sufficient cash from KACC as described above. Cash used for
operations (including $12.0 million of financing costs) was $2.4 million in the
first nine months of 1993 compared with cash provided by operations (including
$1.8 million of financing costs) of $21.9 million in the first nine months of
1992. At December 31, 1993, the Company's total consolidated indebtedness was
$729.4 million. As of such date, $113.6 million of borrowing capacity was unused
under the revolving credit facility of the Credit Agreement, and KACC had
available to it, subject to certain restrictions, up to $15.0 million of
uncommitted credit lines (of which $0.5 million was used). On a pro forma basis,
after giving effect to the Refinancing Transactions, as of December 31, 1993,
the Company's total consolidated indebtedness would have been $715.9 million,
$182.5 million of borrowing capacity would have been unused under the New Credit
Agreement and the Company would have had additional cash available of $48.7
million. The foregoing does not give effect to $73.6 million of guaranteed

Trends." The Company has attempted to lessen the adverse effect of declines in
the price of primary aluminum. See "Sensitivity to Prices; Current Primary
Aluminum Prices Adversely Affect Net Sales and Operating Income."
    
 
SENSITIVITY TO PRICES; CURRENT PRIMARY ALUMINUM PRICES ADVERSELY AFFECT
NET SALES AND OPERATING INCOME
 
     The Company's earnings are sensitive to changes in the prices of alumina,
primary aluminum and fabricated aluminum products and also depend to a
significant degree upon the volume and mix of all products sold. The Company's
average realized prices from sales of alumina and primary aluminum declined
substantially in 1993, 1992, 1991 and 1990 from their high levels of 1989 and
1988.
 
     Although the Company has attempted to lessen the effect of the decline of
primary aluminum and alumina prices through a variety of forward sales
transactions and hedging programs, earnings have been, and are expected to
remain, significantly more sensitive to changes in primary aluminum prices and
revenues derived from the sale of alumina to third parties. Revenues from
alumina sales to third parties declined in 1993 as a result of lower average
realized prices for alumina. Revenues from primary aluminum sales declined as a
result of reduced shipments and lower average realized prices for primary
aluminum in 1993 than in 1992. In 1993, the Company's average realized price
from sales of primary aluminum was approximately $0.56 per pound compared to the
average Midwest U.S. transaction price of approximately $0.54 per pound for such
year. Increased revenues from sales of fabricated aluminum products (as a result
of higher shipments, partially offset by lower unit prices for some fabricated
products) partially offset these decreases in 1993. See "Management's Discussion
and Analysis of Results of Operations -- Fourth Quarter and Preliminary Year End
Results."
 
     The Company has sold forward substantially all of the alumina available to
it in excess of its projected internal smelting requirements for 1994, and a
substantial portion of such excess alumina for 1995. Approximately 95% of 1994
sales and virtually all of 1995 sales were made at prices indexed to future
prices of primary aluminum. Approximately 75% of 1994 sales were made at prices
indexed to future prices of primary aluminum, but with minimum prices that
exceed the Company's estimated cash production costs. The remainder of 1994
sales were made either at fixed prices that exceed the Company's estimated cash
production costs, or are subject to prices indexed to future prices of primary
aluminum but without minimum prices. Approximately 85% of 1995 sales were made
at prices indexed to future prices of primary aluminum, but with minimum prices
that exceed the Company's estimated cash production costs.
 
   
     As of the date of this Prospectus, the Company has sold forward
approximately 75% of its primary aluminum in excess of its projected internal
fabrication requirements in 1994 and approximately 55% of such surplus in 1995
at fixed prices that approximate the current market price of primary aluminum.
Hedging programs already in place would allow the Company to participate in
certain higher market prices, should they materialize, for approximately 40% of
the Company's excess primary aluminum sold forward in 1994, and 100% of the
Company's excess primary aluminum sold forward in 1995.
    
 
     Fabricated aluminum prices, which vary considerably among products, are
heavily influenced by changes in the price of primary aluminum and generally lag
behind primary aluminum prices for periods of up to six months. A significant
portion of the Company's fabricated product shipments consist of body, lid, and
tab stock for the beverage container market. The Company may not be able to
receive increases in primary aluminum prices from its can stock customers as
promptly as in the recent past because of competition from other aluminum
producers and because of excess supply in the industry. Changes in the market
price of primary aluminum also affect the Company's production costs of
fabricated products because they influence the price of aluminum scrap purchased
by the Company and the Company's labor costs, to the extent such costs are
indexed to primary aluminum prices.
 
     While the Company continues to attempt to lessen the adverse effect of
declines in the price of primary aluminum through its variable cost structures,
forward sales and hedging programs, possible future declines in the market price
of primary aluminum would have an adverse effect on the Company's financial
performance. If the Company's average realized sales prices in 1994 for
substantial quantities of its primary aluminum and
 
                                       14

alumina were based on the current market price of primary aluminum (AMT Price of
61.14c per pound for the week ended February 4, 1994), the Company would
continue to sustain net losses in 1994, which would be expected to approximate
the loss in 1993 ($81.5 million) before (a) extraordinary loss and cumulative
effect of changes in accounting principles, (b) the 1993 Facilities Charges and
(c) the Other 1993 Charges. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations," "Business -- Industry Overview"
and "Business -- Sensitivity to Prices and Hedging Programs."
    
 
   
RECENT DEVELOPMENTS IN POWER SUPPLY FOR PACIFIC NORTHWEST OPERATIONS AND
    
RESULTANT PRODUCTION CURTAILMENTS
 
     Electrical power represents an important production cost for the Company at
its domestic smelters in Mead and Tacoma, Washington, and a much smaller portion
of the Company's production costs at its fabricating plant in Trentwood,
Washington (collectively, the "Facilities"). The electricity supply contracts
between the BPA and its direct service industry customers (which consist of 15
energy intensive companies, principally aluminum producers, including the
Company) permit the BPA to interrupt up to 25% of the amount of power which it
normally supplies to such customers.
 
   
     As a result of drought conditions, in January 1993 the BPA reduced the
amount of power it normally supplies to its direct service customers, including
the Company, with respect to the Facilities. In response to such reduction, the
Company removed three reduction potlines from production (two at the Mead
smelter and one at the Tacoma smelter), and purchased substitute power in the
first quarter of 1993 at increased costs. The BPA has notified its direct
service industry customers that it intends to maintain the interruption of 25%
of the amount of power it normally provides to such customers through February
28, 1994. As a result of the BPA power reductions, the Company has operated its
Mead and Tacoma smelters at the reduced operating rates introduced in January
1993, and has operated its Trentwood fabrication facility without any
curtailment of its production. The Company currently anticipates that in 1994 it
will operate the Mead and Tacoma smelters at rates which do not exceed the
current operating rates of 75% of full capacity for such smelters. The Company
cannot predict whether full power will be provided by the BPA after February 28,
1994, or whether power will otherwise become available at a price acceptable to
the Company. The Company will continue to assess its production levels at the
Mead and Tacoma smelters in light of the availability and cost of such power and
other production costs, the market price of primary aluminum, industry inventory
levels and other industry-related and Company-related factors.
    
 
     Effective October 1, 1993, an increase in the base rate BPA charges to its
direct service industry customers for electricity was adopted, which will
increase the Company's production costs at the Mead and Tacoma smelters by
approximately $15.0 million per year (approximately $11.3 million per year based
on the Company's current operating rate of approximately 75% of full capacity).
The rate increase generally is expected to remain in effect for two years.
 
     In the event that the BPA's revenues fall below certain levels prior to
April 1994, the BPA may impose up to a 10% surcharge on the base rate it charges
to its direct service industry customers, effective during the period from
October 1994 through October 1995 (which would increase the Company's production
costs at the Mead and Tacoma smelters by approximately $9.1 million per year
based on the Company's current operating rate of approximately 75% of full
capacity). In addition, in order to comply with certain federal laws and
regulations applicable to endangered fish species, the BPA may be required in
the future to reduce its power generation and to purchase substitute power (at
greater expense) from other sources. The foregoing factors would increase the
Company's operating expenses.
 
INCREASING WORLDWIDE ALUMINUM INVENTORIES AND ADVERSE EFFECTS ON MARKET PRICES
 
     Exports from the Commonwealth of Independent States, additions to smelter
capacities during the past several years, continued high operating rates and
other factors have contributed to a significant increase in primary aluminum
inventories in the Western world. If Western world production and exports from
the Commonwealth of Independent States continue at current levels, primary
aluminum inventory levels will increase further in 1994. The foregoing factors,
among others, have contributed to a significant reduction in
 
                                       15

<PAGE>   18
 
the market price of primary aluminum, and may continue to adversely affect the
market price of primary aluminum in the future. The average price of primary
aluminum was at historic lows in real terms for the year ended 1993, which
significantly and adversely affected the Company's net sales and operating
income for such period. See "Sensitivity to Prices; Current Primary Aluminum
Prices Adversely Affect Net Sales and Operating Income" and
"Business -- Industry Overview -- Recent Industry Trends."
 
ENVIRONMENTAL LITIGATION
 
   
     The Company is subject to a wide variety of international, state and local
environmental laws and regulations (the "Environmental Laws"). From time to
time, the Company is subject, with respect to its current and former operations,
to fines or penalties assessed for alleged breaches of the Environmental Laws
and to claims and litigation based upon such laws. The Company is currently
subject to a number of lawsuits under the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended by the Superfund Amendments
and Reauthorization Act of 1986 ("CERCLA").
    
 
   
     Under CERCLA and other related laws, past disposal of wastes, whether
on-site or at other locations, may result in the imposition of clean-up
obligations by federal or state regulatory authorities. The Company, along with
certain other entities has been named as a potentially responsible party for
remedial costs at certain third-party sites listed on the National Priorities
List under CERCLA. In certain instances, the Company may be exposed to joint and
several liability for remedial action or damages to natural resources, which
could effectively expose the Company to liability for all costs associated with
any such remedial actions irrespective of its degree of culpability for the
environmental damages related thereto. While the ultimate extent of the
Company's liability for pending or potential fines, penalties, remedial costs,
claims and litigation with respect to environmental and other related laws
cannot be determined at this time, management currently believes that the
resolution of the environmental and related litigation to which the Company is a
party (even without giving effect to potential insurance recovery) should not
have a material adverse effect on the Company's consolidated financial position
or results of operations. For a discussion of the Company's environmental
litigation, see "Business -- Environmental Matters" and "-- Legal Proceedings."
    
 
CONTROLLING STOCKHOLDER AND POSSIBLE EFFECTS
 
   
     The Company became an indirect, wholly owned subsidiary of MAXXAM on
October 28, 1988, through the merger of a subsidiary of MAXXAM with and into the
Company (the "Merger"). As of the date of this Prospectus, MAXXAM directly owns
approximately 67% of the Company's Common Stock, assuming the conversion of each
outstanding $.65 Depositary Share into one share of Common Stock (and, after
giving effect to this offering, MAXXAM will directly own approximately 61% of
the Common Stock assuming the conversion of each share of PRIDES into one share
of Common Stock, and approximately 60% if the Underwriters' over-allotment
option is exercised in full), with public stockholders owning the balance. In
the event that MAXXAM sells all of the 2,132,950 $.65 Depositary Shares which it
owns to nonaffiliates, MAXXAM would own approximately 65% of the Company's
Common Stock assuming the conversion of each outstanding $.65 Depositary Share
into one share of Common Stock (and, after giving effect to this offering,
MAXXAM would directly own approximately 58% of the Common Stock assuming the
conversion of each share of PRIDES into one share of Common Stock, and
approximately 58% if the Underwriters' overallotment option is exercised in
full), with public stockholders owning the balance. Accordingly, MAXXAM is able
to determine the outcome of all matters required to be submitted to the
Company's stockholders for approval, including decisions relating to the
election of the directors of the Company, the determination of day-to day
corporate and management policies of the Company, the merger or acquisition of
the Company, the sale of substantially all of the assets of the Company and
other significant corporate transactions. MAXXAM's significant ownership
interest in the Company may discourage third parties from seeking to acquire
control of the Company which may adversely affect the market price of the
Company's equity securities. Mr. Charles E. Hurwitz, Chairman of the Board,
President and Chief Executive Officer of MAXXAM, together with Federated
Development Company ("Federated"), a New York business trust that is wholly
owned by Mr. Hurwitz, members of his immediate family and trusts for the benefit
thereof, collectively own approximately 60.0% of the aggregate voting power of
MAXXAM.

ABSENCE OF PUBLIC MARKET
 
   
     There is no existing market for the shares of PRIDES. The shares of PRIDES
and the Common Stock issuable in respect thereof have been approved for listing
on the NYSE, subject to official notice of issuance. Future trading prices of
the shares of PRIDES will depend on many factors, including, among other things,
the Company's operating results, the market for similar securities and the
trading price of the Company's $.65 Depositary Shares and Common Stock.
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     As of the date of this Prospectus, MAXXAM owns 50,000,000 shares of the
Company's Common Stock (the "MAXXAM Common Stock") and 2,132,950 $.65 Depositary
Shares (the "MAXXAM Depositary Shares"). Sales of the MAXXAM Common Stock or
MAXXAM Depositary Shares by MAXXAM may not be made in a public distribution
unless registered under the Securities Act or sold pursuant to Rule 144
thereunder. On October 13, 1993, the Company filed a registration statement with
the Commission (which has been declared "effective" by the Commission) relating
to the public sale by MAXXAM of the MAXXAM Depositary Shares. Sales of
substantial amounts of the MAXXAM Common Stock or MAXXAM Depositary Shares in
the public market subsequent to the consummation of this offering, and the
possibility that such sales may be made, could adversely affect the prevailing
market price of the Company's equity securities.
 
     In connection with this offering, each of the Company and MAXXAM has agreed
that it will not sell shares of PRIDES, Common Stock, $.65 Depositary Shares or
Series A Shares for specified periods from the date of this Prospectus. See
"Underwriting."

                                USE OF PROCEEDS
 
   
     The net proceeds to be received by the Company from the sale of the shares
of PRIDES are estimated to be approximately $79.9 million. The Company intends
to use such net proceeds to make a non-interest bearing loan to KACC in a
principal amount equal to $28,220,000 (the aggregate dividends scheduled to
accrue on the shares of PRIDES from the issuance date until the Mandatory
Conversion Date) evidenced by an intercompany note (the "Initial Intercompany
Note") and to use the balance of such net proceeds to make a capital
contribution to KACC in the amount of approximately $51.7 million. The Initial
Intercompany Note will mature on December 31, 1997, and will be payable in
quarterly installments on                ,                ,                and
               of each year, commencing                , 1994, and ending
               1997, each quarterly installment to be in the amount of
$1,763,750.
    
 
   
     If the Underwriters' over-allotment option is exercised in full, the
Company intends to use a portion of the additional net proceeds received from
such exercise (estimated to be approximately $12.1 million) to make an
additional non-interest bearing loan to KACC in a principal amount equal to
$4,233,000 evidenced by an additional intercompany note (the "Additional
Intercompany Note" and, together with the Initial Intercompany Note, the
"Intercompany Note") and to use the balance of such net proceeds to make an
additional capital contribution to KACC in the amount of approximately $7.9
million. The Additional Intercompany Note will be identical in all material
respects to the Initial Intercompany Note. In a manner similar to the Initial
Intercompany Note, the Additional Intercompany Note will have payment terms
designed to provide sufficient funds to the Company to enable it to make
dividend payments on the shares of PRIDES issued as a result of the exercise of
the over-allotment option until the Mandatory Conversion Date.
    
 
   
     KACC currently intends to use the funds it receives from the Company for
working capital and general corporate purposes. In connection with this
offering, KACC is concurrently offering $175.0 million of Senior Notes. The net
proceeds of the offering of Senior Notes will be used to reduce outstanding
borrowings under the revolving credit facility of the Credit Agreement ($225.0
million outstanding as of February 4, 1994; the Credit Agreement currently bears
interest at the rate of 6.4% per annum) immediately prior to the effectiveness
of the New Credit Agreement and for working capital and general corporate
purposes. Borrowings and reborrowings under the New Credit Agreement will be
used for working capital and general corporate purposes, including capital
projects. From time to time, the Company undertakes discussions with various
parties relating to the creation of joint ventures or other business
combinations, the acquisition of related businesses and other strategic matters
which management believes may enhance the Company's competitive position. As of
the date of this Prospectus, the Company has not entered into any material
agreements relating to any of the foregoing.

                                DIVIDEND POLICY
 
     The Company expects to make dividend payments on the shares of PRIDES until
the Mandatory Conversion Date out of funds provided to it by KACC pursuant to
the terms of the Intercompany Note. The Intercompany Note will mature on
December 31, 1997, and will be payable in quarterly installments. The
declaration and payment of dividends by the Company on the shares of PRIDES will
be expressly permitted by the terms of the New Credit Agreement to the extent
the Company receives payments on the Intercompany Note.
 
     The Company paid a quarterly dividend of $.05 per share of Common Stock,
commencing with its initial public offering during the third quarter of 1991 and
continuing through the fourth quarter of 1992. The Company's Board of Directors
determined not to declare any dividends on the Common Stock in 1993. The
declaration and payment of dividends on the Common Stock will depend upon the
Company's results of operations, general financial condition, capital needs and
future prospects. On September 30, 1993, and December 31, 1993, the Company paid
a dividend in the amount of $.1625 per $.65 Depositary Share to all holders of
its outstanding $.65 Depositary Shares.
 
   
     Holders of shares of PRIDES will receive shares of Common Stock upon
conversion or redemption of their shares of PRIDES. The declaration and payment
of dividends by KACC on its shares of common stock will be subject to certain
covenants contained in the Senior Note Indenture and the 12 3/4% Note Indenture.
See "Description of Principal Indebtedness -- Existing Indebtedness" for a
discussion of such restrictions. The New Credit Agreement will not permit the
Company or KACC to pay any dividends on their common stock.

         SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA
 
     The following selected historical and pro forma consolidated financial data
should be read in conjunction with the Consolidated Financial Statements of the
Company and the Notes thereto, appearing elsewhere in this Prospectus, and the
information contained in "Management's Discussion and Analysis of Financial
Condition and Results of Operations." The selected historical consolidated
financial data as of and for the years ended December 31, 1992, 1991, 1990 and
1989, as of and for the two months ended December 31, 1988, and for the ten

The selected historical consolidated financial data as of and for the nine
months ended September 30, 1993, and for the nine months ended September 30,
1992, have not been audited, but in the opinion of management contain all
adjustments (consisting of normal recurring adjustments) necessary to present
fairly the financial position and results of operations of the Company as of
such date and for such periods. The financial statements of Predecessor and
Successor are not directly comparable for the reasons set forth in footnote (1)

(1) The acquisition of the Company in the Merger has been recorded as a
    purchase, with the Company's financial results reported through October 31,
    1988 (Predecessor), and for periods subsequent thereto (Successor). In
    accounting for the acquisition, Successor recorded the assets and
    liabilities of Predecessor based upon estimated fair values. At the same
    time, Successor adopted the last-in, first-out (LIFO) method for financial
    reporting purposes for valuing substantially all product inventories.
    Operations of the Company's aluminum smelter and rolling mill at Ravenswood,
    West Virginia, its aluminum recycling facility at Bedford, Indiana, and its
    regional data center at Columbus, Ohio, are not included in the reported
    results of operations of Successor as they were accounted for as assets held

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
     The Company, through KACC, operates in two business segments: bauxite and
alumina, and aluminum processing. The Company's operating results are sensitive
to changes in prices of alumina, primary aluminum, and fabricated aluminum
products, and also depend to a significant degree upon the volume and mix of all
products sold. The following table provides selected operational and financial
information on a consolidated basis with respect to the Company for the years
ended December 31, 1992, 1991, and 1990, and for the nine months ended September
30, 1993 and 1992. As an integrated aluminum producer, the Company uses a
portion of its bauxite, alumina, and primary aluminum production for additional
processing at certain of its other facilities. Intracompany shipments and sales
are excluded from the information set forth below.

RECENT TRENDS
 
     Exports from the Commonwealth of Independent States, additions to smelter
capacities during the past several years, continued high operating rates and
other factors have contributed to a significant increase in primary aluminum
inventories in the Western world. If Western world production and exports from
the Commonwealth of Independent States continue at current levels, primary
aluminum inventory levels will increase further in 1994. The foregoing factors,
among others, have contributed to a significant reduction in the market price of
primary aluminum, and may continue to adversely affect the market price of
primary aluminum in the future.
 
   
     Government officials from the European Union, the United States of America,
Canada, Norway, Australia and the Russian Federation met in a multilateral
conference in January 1994, to discuss the current excess global supply of
primary aluminum. All six participating governments have ratified as a trade
agreement the resulting Memorandum which provides, in part, for (i) a reduction
in Russian Federation primary aluminum production by 300,000 tons per year
within three months of the date of ratification of the Memorandum and an
additional 200,000 tons within the following three months, (ii) improved
availability of comprehensive data on Russian aluminum production and (iii)
certain assistance to the Russian aluminum industry. A Russian Federation Trade
Ministry official has publicly stated that the output reduction would remain in
effect for 18 months to two years, provided that other worldwide production
cutbacks occur, existing trade restrictions on aluminum are eliminated and no
new trade restrictions on aluminum are imposed. The Memorandum does not require
specific levels of production cutbacks by other producing nations. A further
meeting of the participants is scheduled for the end of February 1994. There can
be no assurance that the implementation of the Memorandum will adequately
address the current oversupply of primary aluminum. The Company will continue to
assess its production levels in light of market prices, industry inventory
levels, production costs and user demand and, based on these and other factors,
could determine to curtail production at certain of its facilities in the
future.
    
 
   
     If the Company's average realized sales prices in 1994 for substantial
quantities of its primary aluminum and alumina were based on the current market
price of primary aluminum (AMT Price of 61.14c per pound for the week ended
February 4, 1994) the Company would continue to sustain net losses in 1994,
which would be expected to approximate the loss in 1993 ($81.5 million) before
(a) extraordinary loss and cumulative effect of changes in accounting
principles, (b) the 1993 Facilities Charges and (c) the Other 1993 Charges.
    
 
     KACC announced in October 1993 that it is restructuring its flat-rolled
products operation at its Trentwood plant in the state of Washington, to reduce
that facility's annual operating costs. This effort is in response to
over-capacity in the aluminum rolling industry, flat demand in can stock
markets, and declining demand for aluminum products sold to customers in the
commercial aerospace industry, all of which have resulted in declining prices in
Trentwood's key markets. The Trentwood restructuring is expected to result in
annual cost savings of approximately $50.0 million after it has been fully
implemented (which is expected to occur during the next two years).
 
     Effective October 1, 1993, an increase in the base rate BPA charges to its
direct service industry customers for electricity was adopted, which will
increase the Company's production costs at the Mead and Tacoma smelters by
approximately $15.0 million per year (approximately $11.3 million per year,
based on the current operating rate of approximately 75% of full capacity). The
rate increase is generally expected to remain in effect for two years.
 
FOURTH QUARTER AND YEAR END RESULTS
 
     The Company's net sales totaled $415.9 million in the fourth quarter of
1993, compared with $496.0 million in the fourth quarter of 1992, and $1,719.1
million for the full year 1993, compared with $1,909.1 million for the full year
of 1992. Revenues decreased in the fourth quarter of 1993 as compared to the
fourth quarter of 1992 due principally to lower average realized prices and
shipments of primary aluminum and alumina and lower average realized prices of
most fabricate products, partially offset by increased shipments of fabricated
products during the 1993 period compared with the 1992 period. Revenues
decreased for the full year of 1993 as compared to the full year of 1992 due
principally to lower shipments of primary
 
                                       23

<PAGE>   26
 
aluminum and lower average realized prices of primary aluminum and alumina and,
to a lesser extent, of fabricated products, partially offset by increased
shipments of most fabricated products during 1993 as compared to 1992.
 
     The Company will report a net loss before extraordinary loss and cumulative
effect of changes in accounting principles of $123.1 million (including the 1993
Facilities Charges and the Other 1993 Charges) for the full year of 1993,
compared with net income of $26.9 million for the full year of 1992. The Company
will report a net loss of $66.1 million (including the 1993 Facilities Charges
and the Other 1993 Charges) for the fourth quarter of 1993, compared with net
income of $2.6 million for the fourth quarter of 1992. The Company recognized an
after-tax loss relating to the cumulative effect of changes in accounting
principles of $507.3 million and an after-tax extraordinary loss on early
extinguishment of debt of $21.8 million in the first quarter of 1993. See Note
(1) of "Summary Historical and Pro Forma Consolidated Financial Data."
 
     The fourth quarter results include a pre-tax charge of $35.8 million ($22.6
million after-tax) related to the 1993 Facilities Charges and pre-tax charges of
$30.2 million ($19.0 million after-tax) principally related to the Other 1993
Charges. The Company will also recognize an after-tax reduction of stockholders'
equity of $14.9 million in the fourth quarter of 1993 to reflect the lowering of
the discount rate used to calculate the Company's minimum pension liability. The
Company recognized a pre-tax charge of $29.0 million ($24.2 million after-tax)
related to a reduction in the carrying value of the Company's inventory, pre-tax
income of $14.0 million ($11.7 million after-tax) for non-recurring adjustments
to previously recorded liabilities and reserves, and an after-tax reduction of
stockholders' equity of $6.7 million in the fourth quarter of 1992.
 
NINE MONTHS ENDED SEPTEMBER 30, 1993 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1992
 
     Net Sales
 
     Bauxite and Alumina -- Revenue from net sales of bauxite and alumina to
third parties was $319.6 million in the first nine months of 1993, compared with
$337.6 million in the first nine months of 1992. Revenue from alumina decreased
9% to $255.5 million in the first nine months of 1993 from $280.7 million in the
first nine months of 1992 because lower average realized prices more than offset
increased shipments.
 
     Aluminum Processing -- Revenue from net sales to third parties for the
aluminum processing segment was $983.6 million in the first nine months of 1993,
compared with $1,075.5 million in the first nine months of 1992. Revenue from
primary aluminum decreased 40% to $229.3 million in the first nine months of
1993 from $381.3 million in the same period of 1992 because of lower shipments
and lower average realized prices. Shipments of primary aluminum to third
parties constituted approximately 40% of total aluminum products shipments in
the first nine months of 1993, compared with approximately 50% in the first nine
months of 1992. Revenue from fabricated aluminum products increased 9% to $744.6
million in the first nine months of 1993 from $683.9 million in the same period
of 1992, principally due to an increase in shipments.
 
     Operating Income (Loss)
 
     The Company had an operating loss of $41.4 million in the first nine months
of 1993, compared with operating income of $85.7 million in the first nine
months of 1992.
 
     Bauxite and Alumina -- This segment's operating loss in the first nine
months of 1993 was $1.8 million, compared with income of $46.2 million in the
first nine months of 1992. The decline in earnings is principally due to a
decrease in average realized prices for alumina, partially offset by increased
shipments of alumina. In the 1992 period, the Company realized above-market
prices for significant quantities of alumina sold forward at fixed prices in
prior periods under long-term contracts.
 
   
     Aluminum Processing -- This segment's operating income was $12.6 million in
the first nine months of 1993, compared with $104.2 million in the same period
of 1992. This decrease was caused principally by reduced shipments and lower
average realized prices of primary aluminum. Other contributing factors were
lower production at the Company's smelters in the Pacific Northwest in the 1993
period, as a result of the removal of three reduction potlines from production
at those smelters in January 1993 in response to the BPA's reduction in January
1993 of the amount of power it normally provides to the Company, and the
    
 
                                       24

<PAGE>   27
 
   
increased cost of substitute power in the first quarter of 1993. In the first
nine months of 1993, the Company's average realized price from sales of primary
aluminum was approximately $.57 per pound, compared to the average Midwest U.S.
transaction price of approximately $.55 per pound during such period. In both
the 1993 and 1992 periods, the Company realized above-market prices for
significant quantities of primary aluminum sold forward in prior periods under
long-term contracts.
    
 
     Corporate -- Corporate operating expenses of $52.2 million and $64.7
million in the first nine months of 1993 and 1992, respectively, represented
corporate general and administrative expenses, which are not allocated to the
Company's segments.
 
     Income (Loss) Before Extraordinary Loss and Cumulative Effect of Changes in
Accounting Principles
 
     Loss before extraordinary loss and cumulative effect of changes in
accounting principles was $57.0 million, or $1.05 per common share, in the first
nine months of 1993, compared with income of $24.3 million, or $.42 per common
share, in the first nine months of 1992. This decrease resulted from the lower
operating income previously described, partially offset by a higher credit for
income taxes. See Note 5 of the Notes to Interim Consolidated Financial
Statements.
 
     Extraordinary Loss on Early Extinguishment of Debt
 
     On February 1, 1993, KACC issued $400.0 million aggregate principal amount
of its 12 3/4% Notes. The net proceeds from the sale of the 12 3/4% Notes were
used to retire $321.7 million aggregate principal amount of, and pay premiums
on, the 14 1/4% Notes, to prepay $18.0 million of the term loan under the Credit
Agreement, and to reduce outstanding borrowings under the revolving credit
facility of the Credit Agreement. These transactions resulted in a pre-tax
extraordinary loss of $33.0 million in the first quarter of 1993 ($21.8 million
after taxes), consisting primarily of the write-off of unamortized discount and
deferred financing costs related to the 14 1/4% Notes and the payment of
premiums on the 14 1/4% Notes.
 
     Cumulative Effect of Changes in Accounting Principles
 
     As of January 1, 1993, the Company adopted Statement of Financing
Accounting Standards No. 106, Employers' Accounting for Postretirement Benefits
Other Than Pensions ("SFAS 106"), Statement of Financial Accounting Standards
No. 109, Accounting for Income Taxes ("SFAS 109"), and Statement of Financial
Accounting Standards No. 112, Employers' Accounting for Postemployment Benefits
("SFAS 112").
 
     The cumulative effect of the change in accounting principle for the
adoption of SFAS 106 reduced results of operations by $497.7 million, net of a
related income tax benefit of $234.2 million. The cumulative effect of the
change in accounting principle for the adoption of SFAS 112 reduced results of
operations by $7.3 million, net of a related income tax benefit of $3.5 million.
The new accounting methods have no effect on the Company's cash outlays for
postretirement and postemployment benefits nor will the one-time charge affect
the Company's compliance with its existing debt covenants. The Company reserves
the right, subject to applicable collective bargaining agreements, to amend or
terminate these benefits.
 
     The cumulative effect of the change in accounting principle for the
adoption of SFAS 109 reduced results of operations by $2.3 million. The
implementation of SFAS 109 required the Company to restate certain assets and
liabilities to pre-tax amounts from net-of-tax amounts, originally recorded in
connection with the acquisition of the Company by MAXXAM. See Notes 5, 6 and 7
to Interim Financial Statements.
 
     Net Income (Loss)
 
     The Company recorded a net loss of $586.1 million, or $10.28 per common
share, for the first nine months of 1993 compared with net income of $24.3
million, or $.42 per common share, in the same period of 1992. The principal
reasons for the earnings decline were the cumulative effect of changes in
accounting principles of $507.3 million ($8.85 per common share), the
extraordinary loss of $21.8 million ($.38 per common share) and the operating
losses described above.

  THREE YEARS ENDED DECEMBER 31, 1992
 
     Net Sales
 
     Bauxite and Alumina -- This segment's revenue from net sales of bauxite and
alumina to third parties was $466.5 million in 1992 compared with $550.8 million
in 1991 and $609.4 million in 1990. Revenue from alumina decreased 16% to $390.8
million in 1992 from $466.5 million in 1991, as significantly lower average
realized prices more than offset a 3% increase in alumina shipments.
 
     Revenue from alumina decreased 12% to $466.5 million in 1991 from $529.2
million in 1990 as significantly lower average realized prices more than offset
an 11% increase in alumina shipments, which was principally attributable to
increased production at all three of the Company's alumina refineries. The
remainder of the segment's sales revenues were from sales of bauxite, which
remained about the same throughout the three years, and the portion of sales of
alumina attributable to the minority interest in Alpart.
 
     Aluminum Processing -- Revenue from net sales to third parties for the
aluminum processing segment was $1,442.6 million in 1992 compared with $1,450.0
million in 1991 and $1,485.6 million in 1990. The bulk of the segment's sales
represents the Company's primary aluminum and fabricated aluminum products, with
the remainder attributable to the portion of sales of primary aluminum
attributable to the minority interest in Valco.
 
     Revenue from primary aluminum decreased 4% to $515.0 million in 1992 from
$538.5 million in 1991, as an 8% decrease in average realized prices more than
offset a 4% increase in primary aluminum shipments. Shipments of primary
aluminum to third parties were approximately 51% of total aluminum products
shipments in 1992 compared with approximately 52% in 1991. Revenue from primary
aluminum decreased 2% to $538.5 million in 1991 from $549.2 million in 1990,
primarily because of a 1% decline in shipments. Shipments of primary aluminum to
third parties were approximately 52% of total aluminum products shipments in
1991 compared with approximately 53% in 1990.
 
     Revenue from fabricated aluminum products increased 2% to $913.7 million in
1992 compared with $898.9 million in 1991, primarily because lower average
realized prices were more than offset by a 9% increase in shipments of
fabricated aluminum products. Revenue from fabricated aluminum products
decreased by 2% to $898.9 million in 1991 from $917.0 million in 1990 because of
lower average realized prices.
 
     Operating Income
 
     The Company's operating income in 1992 was $89.9 million, compared with
$216.0 million in 1991 and $376.1 million in 1990. The Company recorded a
pre-tax charge of approximately $29.0 million in the fourth quarter of 1992
because of a reduction in the carrying value of its inventories caused
principally by prevailing lower prices for alumina, primary aluminum, and
fabricated products of $18.8 million and a LIFO inventory liquidation of $10.2
million.
 
     Bauxite and Alumina -- This segment's operating income in 1992 was $62.6
million, a decrease of 58% from $150.0 million in 1991. Operating income in 1991
was $150.0 million, a decrease of 38% from $241.4 million in 1990. In both 1992
compared to 1991, and 1991 compared to 1990, operating income was adversely
affected by a decrease in average realized prices for alumina which more than
offset higher alumina shipments and above-market prices for significant
quantities of alumina sold forward in prior periods under long-term contracts.
 
     Aluminum Processing -- Operating income for the aluminum processing segment
was $104.9 million in 1992, a decrease of 30% from $150.2 million in 1991.
Operating income in 1992 was adversely affected by a decrease in average
realized prices for primary aluminum and most fabricated aluminum products,
partially offset by increased shipments. In both 1992 and 1991, the Company
realized above-market prices for significant quantities of primary aluminum sold
forward in prior periods under long-term contracts. Operating income for the
aluminum processing segment was $150.2 million in 1991, a decrease of 33% from
$222.6 million in 1990. Operating income in 1991 was adversely affected by a
decrease in average realized prices for fabricated aluminum products and, to a
lesser extent, by higher unit production costs for labor and
 
                                       26

raw materials. These decreases in operating income more than offset above-market
prices for significant quantities of primary aluminum sold forward in prior
periods under long-term contracts.
 
     Corporate -- Corporate operating expenses of $77.6 million, $84.2 million,
and $87.9 million in 1992, 1991, and 1990, respectively, represented corporate
general and administrative expenses which were not allocated to segments.
 
     Income Before Income Taxes and Minority Interests
 
     Income before income taxes and minority interests in 1992 was $32.1
million, a decrease of 77% from $142.4 million in 1991. This decrease resulted
from the lower operating income previously described, partially offset by a
decrease in interest expense. Other income remained about the same in 1992 and
1991 as approximately $14.0 million of income for non-recurring adjustments to
previously recorded liabilities and reserves in the fourth quarter of 1992
approximately equaled the receipt of a $12.0 million fee in the first quarter of
1991 from the Company's minority partner in Alpart in consideration for the
execution of an expansion agreement for the Alpart alumina refinery.
 
     Income before income taxes and minority interests in 1991 was $142.4
million, a decrease of 52% from $297.1 million in 1990. This decrease resulted
from the lower operating income previously described, partially offset by an
increase in other income principally due to the receipt of a $12.0 million fee
in the first quarter of 1991 from the Company's minority partner in Alpart as
explained above.
 
     Net Income
 
     The Company earned $26.9 million (or $.47 per common share) in 1992,
compared with $108.4 million (or $2.03 per common share) in 1991 and $213.7
million (or $4.27 per common share) in 1990. The principal reason for the
earnings decline in 1992 compared with 1991 was the decrease in average realized
prices for alumina, primary aluminum, and most fabricated products, partially
offset by an increase in shipments of such products.
 
     The principal reason for the earnings decline in 1991 compared with 1990
was the decrease in price realizations for alumina, primary aluminum, and
fabricated products, partially offset by a significant increase in shipments of
alumina and the Company's forward sales strategy for substantial quantities of
alumina and primary aluminum which yielded better-than-market prices for these
products.
 
FINANCIAL CONDITION AND CAPITAL SPENDING
 
     Cash from Operations
 
     Cash used for operations was $2.4 million in the first nine months of 1993,
compared with cash provided by operations of $21.9 million in the first nine
months of 1992. Cash flow from operations was $26.3 million in 1992, compared
with $135.0 million in 1991 and $192.6 million in 1990. The decrease in 1992
compared with 1991 was primarily because of the decline in net income and a
$66.3 million decrease in previously withdrawn equity resulting from the excess
of current market value over the premiums paid in certain option contracts. The
decrease in 1991 compared with 1990 was mostly due to a lower level of net
income in 1991, partially offset by the withdrawal of equity in certain option
contracts. The equity withdrawal from these option contracts during 1991
increased by $52.9 million over 1990.
 
     Capital Expenditures
 
     The Company's capital expenditures of approximately $300.2 million (of
which $42.6 million was funded by the Company's minority partners in certain
joint ventures) during the three years ended December 31, 1993, were made
primarily to improve production efficiency, reduce operating costs, expand
capacity at existing facilities, and construct new facilities. Total
consolidated capital expenditures were $67.7 million in 1993 compared with
$114.4 million in 1992 and $118.1 million in 1991 (of which $9.4 million, $17.1
million and $16.1 million were funded by the minority partners in certain
foreign joint ventures in 1993, 1992 and 1991, respectively). Total consolidated
capital expenditures (of which approximately up to 5% is expected to
 
                                       27

<PAGE>   30
 
be funded by the minority partners in certain foreign joint ventures) are
expected to be in the range of $50 million to $75 million per year in the years
1994-1996.
 
     Capital Structure
 
   
     The offering of the PRIDES, the concurrent offering by KACC of $175.0
million aggregate principal amount of Senior Notes and the replacement of the
Credit Agreement are the final steps of a comprehensive refinancing plan which
the Company began in January 1993. The plan is intended to extend the maturities
of the Company's outstanding indebtedness, to enhance its liquidity and to raise
new equity capital.
    
 
   
     As of December 31, 1992, the Company's long-term indebtedness consisted
principally of $321.7 million aggregate amount of the 14 1/4% Notes and the
Credit Agreement. KACC refinanced the 14 1/4% Notes through the issuance in
February 1993 of $400.0 million aggregate principal amount of the 12 3/4% Notes.
In addition, on January 24, 1994, KACC entered into the Commitment Letter to
replace the Credit Agreement ($225.0 million outstanding as of February 4, 1994)
with the New Credit Agreement. Bank of America and BA have committed, subject to
certain terms and conditions, to provide the full $250.0 million of the New
Credit Agreement.
    
 
   
     As of December 31, 1993, the Company's total consolidated indebtedness was
$729.4 million, and $113.6 million of borrowing capacity was unused under the
revolving credit facility of the Credit Agreement. On a pro forma basis, after
giving effect to the sale of the PRIDES, the sale of the Senior Notes and the
effectiveness of the New Credit Agreement, as of December 31, 1993, the
Company's total consolidated indebtedness would have been $715.9 million, $182.5
million of borrowing capacity would have been unused under the New Credit
Agreement and the Company would have had additional cash available of $48.7
million. See "Capitalization."
    
 
   
     To increase its equity capital, the Company consummated a public offering
of its $.65 Depositary Shares in June 1993 pursuant to which the Company
realized net proceeds of approximately $119.3 million. The Company will realize
additional net proceeds of approximately $79.9 million as a result of the sale
of the PRIDES. See "-- Debt Service and Capital Expenditure Requirements" below.
    
 
   
     After giving effect to the Refinancing Transactions, the scheduled maturity
of the Company's long-term indebtedness through 1998 will be substantially
reduced.
    
 
   
         Debt Service and Capital Expenditure Requirements.  Under the terms of
the Company's existing Credit Agreement ($225.0 outstanding as of February 4,
1994), which is expected to be replaced by the New Credit Agreement, KACC
expects to be able to satisfy its debt service and capital expenditures
requirements through at least June 30, 1994, from cash flows generated by
operations and, to the extent necessary, from borrowings under the revolving
credit facility of the Credit Agreement. In the event the Credit Agreement is
not replaced by the New Credit Agreement, there can be no assurance that KACC
will be able to satisfy the covenants under the existing Credit Agreement on or
after June 30, 1994. After giving effect to the Refinancing Transactions, KACC
expects that it will be able to satisfy its debt service and capital expenditure
requirements through at least December 31, 1995, from cash flows generated by
operations and, to the extent necessary, from borrowings under the New Credit
Agreement. See "Description of Principal Indebtedness -- The New Credit
Agreement." The offering of the shares of PRIDES, the offering of the Senior
Notes and the effectiveness of the New Credit Agreement will be conditioned upon
the simultaneous closing of all such transactions.
    
 
     In connection with the offering of the $.65 Depositary Shares in June 1993,
the Company made a non-interest bearing loan to KACC in the principal amount of
$37,796,753 (an amount equal to the aggregate dividends scheduled to accrue on
the Series A Shares issued in June 1993 from the issuance date until the date on
which such Series A Shares mandatorily convert into shares of the Company's
Common Stock). The loan is evidenced by an intercompany note which matures on
June 29, 1996, and is payable in quarterly installments. As of December 31,
1993, the aggregate principal amount of such intercompany note was $31,497,294.
 
     The Company expects to make dividend payments on the shares of PRIDES out
of funds provided to it by KACC pursuant to the terms of the Intercompany Note.
The declaration and payment of dividends by the
 
                                       28

<PAGE>   31
 
Company on the shares of PRIDES will be expressly permitted by the terms of the
New Credit Agreement to the extent the Company receives payments on the
Intercompany Note. See "Risk Factors -- Restrictions on and Factors Affecting
Ability to Pay Dividends; Subordination of Intercompany Note; Termination of
Intercompany Note."
 
   
         Dividends and Distributions.  The New Credit Agreement will not permit
the Company or KACC to pay any dividends on their common stock. The declaration
and payment of dividends by KACC on its shares of common stock will be subject
to certain covenants contained in the Senior Note Indenture and the 12 3/4% Note
Indenture. See "Description of Principal Indebtedness."
    
 
         Other Obligations.  On February 1, 1993, KACC issued $400.0 million
aggregate principal amount of its 12 3/4% Notes. The net proceeds from the sale
of the 12 3/4% Notes were used to retire $321.7 million aggregate principal
amount of, and pay premiums on, the 14 1/4% Notes, to prepay $18.0 million of
the term loan under the Credit Agreement, and to reduce outstanding borrowings
under the revolving credit facility of the Credit Agreement. These transactions
resulted in a pre-tax extraordinary loss of approximately $33.0 million in the
first quarter of 1993 ($21.8 million after taxes), consisting primarily of the
write-off of unamortized discount and deferred financing costs related to the
14 1/4% Notes and the payment of premiums on the 14 1/4% Notes. The obligations
of KACC with respect to the 12 3/4% Notes are guaranteed, jointly and severally,
by certain subsidiaries of KACC. The 12 3/4% Note Indenture contains, among
other things, restrictions on the ability of KACC and its subsidiaries to incur
debt, undertake transactions with affiliates, and pay dividends. See
"Description of Principal Indebtedness."
 
     In December 1992, KACC entered into an installment sale agreement (the
"Sale Agreement") with the Parish of St. James, Louisiana (the "Louisiana
Parish"), in connection with which the Louisiana Parish issued $20.0 million
aggregate principal amount of its 7 3/4% Bonds due August 1, 2022 (the "Gramercy
Bonds"), to finance the construction of certain solid waste disposal facilities
at KACC's Gramercy plant. The proceeds from the sale of the Gramercy Bonds were
deposited into a construction fund and may be withdrawn, from time to time,
pursuant to the terms of the Sale Agreement and the indenture related thereto.
At December 31, 1993, $10.8 million remained in the construction fund. The Sale
Agreement requires KACC to make payments to the Louisiana Parish in installments
due on the dates and in the amounts required to permit the Louisiana Parish to
satisfy all of its payment obligations under the Gramercy Bonds.
 
     The Company has historically participated in various raw material joint
ventures outside the United States. At December 31, 1993, the Company was
unconditionally obligated for $73.6 million of indebtedness of one such joint
venture affiliate.

                                    BUSINESS
INDUSTRY OVERVIEW
 
     Primary aluminum is produced by the refining of bauxite (the major
aluminum-bearing ore) into alumina (the intermediate material) and the reduction
of alumina into primary aluminum. Approximately two pounds of bauxite are
required to produce one pound of alumina, and approximately two pounds of
alumina are required to produce one pound of primary aluminum. Aluminum's
valuable physical properties include its light weight, corrosion resistance,
thermal and electrical conductivity and high tensile strength.
 
     Demand
 
   
     The packaging and transportation industries are the principal consumers of
aluminum in the United States, Japan and Western Europe. In the packaging
industry, which accounted for approximately 22% of consumption in 1992,
aluminum's recyclability and weight advantages have enabled it to gain market
share from steel and glass, primarily in the beverage container area. The
aluminum packaging market in the United States, Japan and Western Europe grew at
a rate of approximately 4.0% per year during the period 1982-1992, and total
United States aluminum beverage can shipments increased at a rate of
approximately 2.5% in 1993, 1.5% in 1992, 3.9% in 1991 and 6.0% in 1990. Nearly
all beer cans and approximately 95% of the soft drink cans manufactured for the
United States market are made of aluminum. Despite the flat demand currently
being experienced in the can stock market, growth in the packaging area is
generally expected to continue in the 1990s due to general population increase
and to further penetration of the beverage can market in Western Europe and
Japan, where aluminum cans are a substantially lower percentage of the total
beverage container market than in the United States.
    
 
     In the transportation industry, which accounted for approximately 28% of
aluminum consumption in the United States, Japan and Western Europe in 1992,
automotive manufacturers use aluminum instead of steel or copper for an
increasing number of components, including radiators, wheels and engines, in
order to meet more stringent environmental and fuel efficiency requirements
through vehicle weight reduction. Management believes that sales of aluminum to
the transportation industry have considerable growth potential due to projected
increases in the use of aluminum in automobiles. According to industry sources,
aluminum content in United States automobiles nearly doubled in the last fifteen
years to an average of 191 pounds per vehicle and the amount of aluminum
consumed in the manufacture of Japanese automobiles more than doubled from 1983
to 1990. Management believes that the use of aluminum in automobiles in the
United States and Japan will approximately double between 1991 and 2006.
 
     Supply
 
     As of year-end 1993, Western world aluminum capacity from 109 smelting
facilities was approximately 16.4 million tons per year. Net exports of aluminum
from the Commonwealth of Independent States to the West increased substantially
from 1990 levels during the period from 1991 through 1993, and have contributed
to a significant increase in London Metal Exchange stocks of primary aluminum.
 
   
     Based upon information currently available, the Company believes that only
moderate additions will be made during 1994-1995 to Western world alumina and
primary aluminum production capacity; however, due to the decline of primary
aluminum prices from January 1, 1991, through the date of this Prospectus, and
other factors, curtailments or permanent shutdowns have been announced, to
management's knowledge, with respect to approximately 2.6 million tons of
primary aluminum production capacity. New alumina and primary aluminum
facilities generally require a four to five year design, engineering and
construction period.

     Recent Industry Trends
 
     The aluminum industry has been cyclical and the market prices of alumina
and primary aluminum have been volatile from time to time. During 1989, tight
supply conditions for alumina and strong demand for primary aluminum resulted in
unusually high spot prices for alumina. During 1990, a moderate surplus of
alumina supply developed due to new alumina production from two facilities that
had been restarted in prior years (including the Company's Alpart refinery) and
increased production at other refineries. Furthermore, recent curtailments of
primary aluminum production in response to declining ingot prices have increased
the surplus of alumina supply. Since 1990, spot prices of alumina have declined
substantially due to these factors and slow economic growth in major aluminum
consuming countries. Contract prices for deliveries of alumina in 1993 were in a
lower range than the ranges applicable during the past several years. As a
result of expansions of alumina refineries during 1992-1993, the current surplus
of alumina is expected to continue.
 
     During 1989 and 1990, primary aluminum smelters throughout the world
operated at near capacity levels. This factor, combined with increased
production from smelter capacity additions during 1989 and 1990, resulted in a
reduction of the market price of primary aluminum from 1988 peak prices.
Additions to smelter capacity in 1991, 1992 and 1993, continued high operating
rates in the Western world and slow economic growth in major aluminum consuming
countries as well as exports from the Commonwealth of Independent States have
contributed to an oversupply of primary aluminum and a significant increase in
primary aluminum inventories in the Western world. If Western world production
and exports from the Commonwealth of Independent States continue at current
levels, primary aluminum inventory levels are expected to increase further in
1994. The foregoing factors have contributed to a significant reduction in the
market price of primary aluminum, and may continue to adversely affect the
market price of primary aluminum in the future. The average price of primary
aluminum was at historic lows in real terms for the year ended 1993. See
"-- Sensitivity to Prices and Hedging Programs -- Alumina and Primary Aluminum."
 
   
     Government officials from the European Union, the United States of America,
Canada, Norway, Australia and the Russian Federation met in a multilateral
conference in January 1994, to discuss the current excess global supply of
primary aluminum. All six participating governments have ratified as a trade
agreement the resulting Memorandum which provides, in part, for (i) a reduction
in Russian Federation primary aluminum production by 300,000 tons per year
within three months of the date of ratification of the
    
 
                                       31

<PAGE>   34
 
   
Memorandum and an additional 200,000 tons within the following three months,
(ii) improved availability of comprehensive data on Russian aluminum production
and (iii) certain assistance to the Russian aluminum industry. A Russian
Federation Trade Ministry official has publicly stated that the output reduction
would remain in effect for 18 months to two years, provided that other worldwide
production cutbacks occur, existing trade restrictions on aluminum are
eliminated and no new trade restrictions on aluminum are imposed. The Memorandum
does not require specific levels of production cutbacks by other producing
nations. A further meeting of the participants is scheduled for the end of
February 1994. There can be no assurance that the implementation of the
Memorandum will adequately address the current oversupply of primary aluminum.
See "-- Sensitivity to Prices and Hedging Programs -- Alumina and Primary
Aluminum." The Company will continue to assess its production levels in light of
market prices, industry inventory levels, production costs and user demand and,
based on these and other factors, could determine to curtail production at
certain of its facilities in the future.
    
 
   
BUSINESS STRATEGY
    
 
     The Company has made significant changes in the mix of products sold to
customers by disposing of selected assets, restarting and increasing its
percentage ownership interest in the Alpart alumina refinery, and increasing
production of alumina at Gramercy, Louisiana, and QAL in Australia. The
percentage of the Company's alumina production sold to third parties increased
from approximately 35% in 1987 to approximately 71% in 1993, and the percentage
of its primary aluminum production sold to third parties increased from
approximately 20% in 1987 to approximately 56% in 1993.
 
     The Company has concentrated its fabricated products operations on the
beverage container market (which historically has been recession-resistant);
high value-added, heat-treated sheet and plate products for the aerospace
industry; hubs, wheels and other products for the truck, trailer and shipping
container industry; parts for air bag canisters and other automotive components;
and distributor markets for a variety of semi-fabricated aluminum products.
Since January 1, 1989, the Company has constructed four new fabrication
facilities and has modernized and expanded others, with the objective of
reducing manufacturing costs and expanding sales in selected product markets in
which the Company has production expertise, high quality capability, and
geographic and other competitive advantages.
 
     The Company has taken steps to control and reduce costs, improved the
efficiency and increased the capacity of its alumina and primary aluminum
production and fabricating operations, modernized its facilities, and
streamlined and decentralized its management structure to reduce corporate
overhead and shift decision-making and accountability to its business units. In
October 1993, KACC announced that it is restructuring its flat-rolled products
operation at its Trentwood plant in Spokane, Washington, to reduce that
facility's annual operating costs. This effort is in response to over-capacity
in the aluminum rolling industry, flat demand in can stock markets, and
declining demand for aluminum products sold to customers in the commercial
aerospace industry, all of which have resulted in declining prices in
Trentwood's key markets. The Trentwood restructuring is expected to result in
annual cost savings of approximately $50.0 million after it has been fully
implemented (which is expected to occur during the next two years).
 
     From 1980 to 1993, on a per employee basis, alumina production increased by
approximately 54% at the Company's Gramercy alumina refinery; fabricated product
shipments increased by approximately 128% at the Trentwood fabricating facility;
sales volume for aluminum operations as a whole increased by over 300% and the
average life of reduction cells used to produce aluminum at the Company's
smelters improved by approximately 102%. Primary aluminum production at the
Company's Mead and Tacoma smelters was curtailed in 1993 because of a power
reduction imposed by the BPA which reduced the operating rates for such
smelters. From 1980 to 1992, prior to the BPA power reductions, on a per
employee basis, primary aluminum production increased by approximately 72% and
39%, respectively, at the Mead and Tacoma smelters, and from 1980 to 1993,
subsequent to the BPA power reductions, such primary aluminum production
increased by approximately 36% and 15%, respectively, at such smelters. In
addition, from 1985 to 1992, the Trentwood facility's recovery rate (the
relative amount of fabricated product manufactured from a quantity of primary
aluminum) improved by approximately 30% and its promise performance rate (a
measure of ability to meet delivery dates) improved by approximately 23%. The
Company's average kilowatt hours of
 
                                       32

<PAGE>   35
 
electricity utilized per ton of primary aluminum production was also reduced by
approximately 13% from 1980 to 1993 through process improvements.
 
     The Company has also attempted to lessen its exposure to possible future
declines in the market prices of alumina and primary aluminum by entering into
fixed and variable rate power and fuel supply contracts, and a labor contract
with the United Steelworkers of America which provides for semi-variable
compensation with respect to approximately 73% of the Company's domestic hourly
work force. See "-- Production Operations" and "-- Employees."
 
SENSITIVITY TO PRICES AND HEDGING PROGRAMS
 
     The Company's earnings are sensitive to changes in the prices of alumina,
primary aluminum and fabricated aluminum products, and also depend to a
significant degree upon the volume and mix of all products sold. Consequently,
the Company has developed strategies to mitigate its exposure to possible
further declines in the market prices of alumina and primary aluminum while
retaining the ability to participate in favorable pricing environments that may
materialize. See "Risk Factors -- Sensitivity to Prices; Current Primary
Aluminum Prices Adversely Affect Net Sales and Operating Income."
 
     Alumina and Primary Aluminum
 
     The Company's production capacity for alumina significantly exceeds the
requirements of its aluminum smelters. As a result of the restart of, an
increased percentage ownership interest in, and the increased capacity of, the
Alpart refinery in Jamaica, increased production at the Company's other alumina
refineries and the sale of its Ravenswood aluminum smelter, alumina production
and sales to third parties increased further in 1992, 1991 and 1990 following a
significant increase in 1989. These sales, combined with favorable contract
sales prices during 1992, 1991 and 1990, and strong spot alumina prices during
1989, made a significant contribution to operating results during 1992, 1991,
1990 and 1989.
 
     The tight supply conditions and consequent high prices for alumina which
existed in 1989 have been alleviated as a result of increased production and
other factors, including reduced demand due to the economic recession. Average
realized alumina prices for each of 1993, 1992, 1991 and 1990 declined
significantly from the previous year and were significantly below their 1989
high levels. Although the Company has attempted to lessen the effect of such
declines through forward sales transactions and hedging programs described
below, earnings have been, and are expected to remain, significantly more
sensitive to changes in primary aluminum prices and revenues derived from the
sale of alumina to third parties. Revenues from alumina sales to third parties
declined in 1993 as a result of lower average realized prices for alumina. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Recent Trends."
 
     The Company has also sold forward substantially all of the alumina
available to it in excess of its projected internal smelting requirements for
1994, and a substantial portion of such excess alumina for 1995. Approximately
95% of 1994 sales and virtually all of 1995 sales were made at prices indexed to
future prices of primary aluminum. Approximately 75% of 1994 sales were made at
prices indexed to future prices of primary aluminum, but with minimum prices
that exceed the Company's estimated cash production costs. The remainder of 1994
sales were made either at fixed prices that exceed the Company's estimated cash
production costs, or are subject to prices indexed to future prices of primary
aluminum but without minimum prices. Approximately 85% of 1995 sales were made
at prices indexed to future prices of primary aluminum, but with minimum prices
that exceed the Company's estimated cash production costs.
 
   
     As of the date of this Prospectus, the Company has sold forward at fixed
prices approximately 75% of its primary aluminum in excess of its projected
internal fabrication requirements in 1994 and approximately 55% of such surplus
in 1995 at fixed prices that approximate the current market price of primary
aluminum. Hedging programs already in place would allow the Company to
participate in certain higher market prices, should they materialize, for
approximately 40% of the Company's excess primary aluminum sold forward in 1994,
and 100% of the Company's excess primary aluminum sold forward in 1995.
    
 
     Primary aluminum prices have historically been cyclical and, from time to
time, volatile. During 1991, average realized prices from sales of primary
aluminum remained about the same as in 1990, even though market prices declined
significantly, as a result of the Company's forward sales and hedging programs
that
 
                                       33

<PAGE>   36
 
enabled the Company to sell significant quantities of primary aluminum at above
market prices. In 1992, the Company realized an average price of $0.66 per pound
while the average Midwest U.S. transaction price was approximately $0.58 per
pound, as a result of the Company's forward sales and hedging programs that
enabled the Company to sell significant quantities of primary aluminum at above
market prices. In 1993, the Company's average realized price from sales of
primary aluminum was approximately $0.56 per pound compared to the average
Midwest U.S. transaction price of approximately $0.54 per pound during such
period.
 
     In 1991 and 1990, the Company sold to third parties approximately
two-thirds of the primary aluminum it produced, with the balance of the primary
aluminum production used in the Company's fabrication operations. Approximately
70% of the Company's primary aluminum was sold to third parties in 1992, and
approximately 56% in 1993 (primarily because of the curtailment of its
production of primary aluminum in the Pacific Northwest caused by the BPA power
reduction and increased use of the Company's primary aluminum in its fabrication
operations).
 
   
     While the Company continues to attempt to lessen the adverse effect of
declines in the price of primary aluminum through its variable cost structures,
forward sales and hedging programs, possible future declines in the market price
of primary aluminum would have an adverse effect on the Company's financial
performance. If the Company's average realized sales prices in 1994 for
substantial quantities of its primary aluminum and alumina were based on the
current market price of primary aluminum (AMT Price of 61.14c per pound for the
week ended February 4, 1994), the Company would continue to sustain net losses
in 1994, which would be expected to approximate the loss in 1993 ($81.5 million)
before (a) extraordinary loss and cumulative effect of changes in accounting
principles, (b) the 1993 Facilities Charges and (c) the Other 1993 Charges.
    
 
   
     The following table indicates the monthly average Midwest U.S. transaction
price for primary aluminum (the "AMT Price") for each of the months from January
1989 through January 1994 as reported by Metals Week. The AMT Price for the week
ended February 4, 1994, as reported by Metals Week, was 61.14 cents per pound.

     In response to the low price of primary aluminum caused by the current
surplus, a number of companies have closed smelting facilities. In addition, in
response to certain power reductions undertaken by the BPA in the Pacific
Northwest, a number of companies (including the Company) have curtailed or
shutdown production capacities at their smelter facilities in the Pacific
Northwest. The Company will continue to assess its production levels in light of
market prices, industry inventory levels, production costs and user demand and,
based on these and other factors, could determine to curtail production at
certain of its facilities in the future. See also "Business -- Industry
Overview -- Recent Industry Trends."
    
 
     Fabricated Products
 
     Fabricated aluminum prices, which vary considerably among products, are
heavily influenced by changes in the price of primary aluminum and generally lag
behind primary aluminum prices for periods of up to six months. A significant
portion of the Company's fabricated product shipments consist of body, lid and
tab stock for the beverage container market. The Company may not be able to
receive increases in primary aluminum
 
                                       34

<PAGE>   37
 
prices from its can stock customers as promptly as in the recent past because of
competition from other aluminum producers and because of excess supply in the
industry. The Company also ships fabricated products to customers in the
aerospace market. Aluminum demand in the aerospace market is decreasing as a
result of the structural contraction of the defense industry caused by the end
of the cold war. In addition, the commercial aerospace market is experiencing a
cyclical downturn in business due to the recent economic recessions in the
United States, Canada, Australia and the United Kingdom, and slow economic
growth in other countries.
 
     Changes in the market price of primary aluminum also affect the Company's
production costs of fabricated products because they influence the price of
aluminum scrap purchased by the Company and the Company's labor costs, to the
extent such costs are indexed to primary aluminum prices. Following significant
increases in the price of primary aluminum, the prices realized for fabricated
aluminum products were at relatively high levels throughout 1990, 1989 and 1988.
The average realized prices for fabricated aluminum products declined during
1991, reflecting the lower primary aluminum prices prevailing during such year,
and continued to decline during 1992 and 1993. Revenue from fabricated aluminum
products increased 7% to $981.4 million in 1993 compared with $913.7 million in
1992, primarily because of an 8% increase in shipments of fabricated aluminum
products.

     The Company's operations are conducted through decentralized business units
which compete throughout the aluminum industry:
 
     - The Alumina Business Unit, which mines bauxite and obtains additional
       bauxite tonnage under long-term contracts, produced approximately 9% of
       Western world alumina in 1992. During 1993, the Company utilized
       approximately 82% of its bauxite production at its alumina refineries and
       the remainder was either sold to third parties or tolled into alumina by
       a third party. In addition, during 1993 the Company utilized
       approximately 29% of its alumina for internal purposes and sold the
       remainder to third parties. The Company's share of total Western world
       alumina capacity was 8% in 1993.
 
     - The Primary Aluminum Products Business Unit operates two domestic
       smelters wholly owned by the Company and two foreign smelters in which
       the Company holds significant ownership interests. In 1993, the Company
       utilized approximately 44% of its primary aluminum for internal purposes
       and sold the remainder to third parties. The Company's share of total
       Western world primary aluminum capacity was 3% in 1993.
 
     - Fabricated products are manufactured by three Business
       Units -- Flat-Rolled Products, Extruded Products (including rod and bar),
       and Forgings and Castings -- which manufacture a variety of fabricated
       products (including body, lid and tab stock for beverage containers,
       sheet and plate products, screw machine stock, redraw rod, forging stock,
       truck wheels and hubs, air bag canisters and other forgings and castings
       and extruded products) and which operate plants located in principal
       marketing areas of the United States and Canada. Substantially all of the
       primary aluminum utilized in the Company's fabricated products operations
       is obtained through the Company, with the balance of
 
                                       35

       the metal utilized in its fabricated products operations obtained from
       scrap metal purchases. In 1993, the Company shipped approximately 373,200
       tons of fabricated aluminum products to third parties, which accounted
       for approximately 6% of the total tonnage of United States domestic
       fabricated shipments for such year.

(1) Although the Company owns 49% of Kaiser Jamaica Bauxite Company, it has the
     right to receive all of such entity's output.
 
(2) Alpart bauxite is refined into alumina at the Alpart refinery.
 
     Bauxite mined in Jamaica by Kaiser Jamaica Bauxite Company ("KJBC") is
refined into alumina at the Company's plant at Gramercy, Louisiana, or is sold
to third parties. In 1979, the Government of Jamaica granted the Company a
mining lease for the mining of bauxite sufficient to supply the Company's then-
existing Louisiana alumina refineries at their annual capacities of 1,656,000
tons per year until January 31, 2020 (KJBC has announced that it intends to
curtail production of bauxite by 500,000 tons per year). Alumina from the
Gramercy plant is sold to third parties. The Company has entered into a series
of medium-term contracts for the supply of natural gas to the Gramercy plant.
The price of such gas varies based upon certain spot natural gas prices, with
floor and ceiling prices applicable to approximately one-half of the delivered
gas. The Company has, however, established a fixed price for a portion of the
delivered gas through a hedging program.
 
     Alpart holds bauxite reserves and owns an alumina plant located in Jamaica.
The Company has a 65% interest in Alpart and Hydro Aluminium a.s ("Hydro") owns
the remaining 35% interest. The Company has management responsibility for the
facility on a fee basis. The Company and Hydro have agreed to be responsible for
their proportionate shares of Alpart's costs and expenses. Alpart is engaged in
a program of modernization and expansion of its facilities. As a part of that
program, the capacity of the Alpart alumina refinery has been increased to
1,450,000 tons per year as of December 31, 1992. In 1981, the Government of
Jamaica granted Alpart a mining lease covering bauxite reserves sufficient to
operate the Alpart plant until December 31, 2019. In connection with the
expansion program, the Alpart partners have entered into an agreement with the
Government of Jamaica designed to assure that sufficient reserves of bauxite
will be available to Alpart to operate its refinery, as it has been expanded and
as it may be expanded through the year 2024 (to a capacity of 2,000,000 tons per
year).
 
     In mid-1990, Alpart entered into a five-year agreement for the supply of
substantially all of its fuel oil, the refinery's primary energy source. In
February 1992, this agreement was extended for one year and the quantity of fuel
oil to be supplied was increased. The price for 80% of the initial quantity
remains fixed at a price which prevailed in the fourth quarter of 1989; the
price for 80% of the increased quantity is fixed at a negotiated price; and the
price for the balance of the initial and increased quantities was based upon
certain spot fuel oil prices plus transportation costs. Alpart has purchased all
of the quantities of fuel oil which could be purchased based upon certain spot
fuel oil prices under both the initial and extended agreements.

     The Company holds a 28.3% interest in QAL, which owns the largest and one
of the most efficient alumina refineries in the world, located in Queensland,
Australia. QAL refines bauxite into alumina, essentially on a cost basis, for
the account of its stockholders pursuant to long-term tolling contracts. The
stockholders, including the Company, purchase bauxite from another QAL
stockholder pursuant to long-term supply contracts. The Company has contracted
to take approximately 751,000 tons per year of capacity or pay standby charges.
The Company is unconditionally obligated to pay amounts calculated to service
its share ($73.6 million at December 31, 1993) of certain debt of QAL, as well
as other QAL costs and expenses, including bauxite shipping costs. An expansion
project, completed at the end of 1990, increased QAL's annual production
capacity to approximately 3,300,000 tons, of which approximately 934,000 tons
are available to the Company.
 
     The Company's principal customers for bauxite and alumina consist of large
and small domestic and international aluminum producers that purchase bauxite
and reduction-grade alumina for use in their internal refining and smelting
operations and trading intermediaries who resell raw materials to end-users. In
1993, the Company sold all of its bauxite to one customer and sold alumina to
thirteen customers, the largest and top five of which accounted for
approximately 22% and 79% of such sales, respectively. Among alumina producers,
the Company believes it is now the world's second largest seller of alumina to
third parties. The Company's strategy is to sell a substantial portion of the
bauxite and alumina available to it in excess of its internal refining and
smelting requirements pursuant to forward sales contracts. See "-- Sensitivity
to Prices and Hedging Programs." Marketing and sales efforts are conducted by
senior executives of the Alumina Business Unit and the Company.

    Northwest Operations and Resultant Production Curtailments."
 
     The Company owns two smelters located at Mead and Tacoma, Washington, where
alumina is processed into primary aluminum. The Mead facility uses pre-bake
technology; the Tacoma plant uses Soderberg technology. Both smelters have
achieved significant production efficiencies in recent years through retrofit
technology, cost controls and semi-variable wage and power contracts, leading to
increases in production volume and enhancing their ability to compete with newer
smelters. At the Mead plant, the Company has converted to welded anode
assemblies to increase energy efficiency, has reduced the number of anodes used
in the smelting process, has changed from pencil to liquid pitch to produce
carbon anodes which achieved environmental and operating savings, and is engaged
in efforts to increase production through the use of improved, higher-efficiency
reduction cells. In 1992, improved performance was achieved at Mead and Tacoma
in the areas of energy efficiency and hot metal production. Both the Mead and
Tacoma plants operated at approximately full rated capacity during 1991-1992,
but operated at less than rated capacity
 
                                       37

throughout 1993, as a result of a power reduction imposed by the BPA, which is
discussed below. The electricity supply contracts between the BPA and the
Company expire in 2001. Through June 1996, the Company pays for power on a basis
which varies, within certain limits, with the market price of primary aluminum,
and thereafter the Company will pay for power at variable rates to be
negotiated. During 1993, the Company paid for power under its power supply
contract with the BPA at the floor rate. The Tacoma facility produces high
grade, continuous cast, redraw rod, which currently commands a premium price in
excess of primary aluminum prices. The Mead facility produces primary aluminum,
almost all of which is used at the Company's Trentwood fabricating facility and
the balance of which is sold to third parties.
 
     The Company manages, and holds a 90% interest in, the Valco aluminum
smelter in Ghana. The Valco smelter uses pre-bake technology. The smelter
processes alumina supplied by the Company and the other participant into primary
aluminum under long-term tolling contracts which provide for proportionate
payments by the participants in amounts intended to pay not less than all of
Valco's operating and financing costs. The Company's share of the primary
aluminum is sold to third parties.
 
     Power for the Valco smelter is supplied under an agreement which expires in
1997, subject to Valco's right to extend the agreement for 20 years. The
agreement indexes the price of two-thirds of the contract quantity to the market
price of primary aluminum and fixes the price for the remainder, and provides
for a review and adjustment of the base power rate and the price index every
five years. The Valco smelter restarted production early in 1985 after being
closed for more than two years due to lack of rainfall and the resultant
hydroelectricity shortage. The Company believes that there has been sufficient
rainfall and water storage such that an adequate supply of electricity for the
Valco plant at its current operating rate is probable for at least one year.
 
     The Company has a 49% interest in the Anglesey Aluminium Limited
("Anglesey") aluminum smelter and port facility at Holyhead, Wales. The Anglesey
smelter uses pre-bake technology. The Company supplies 49% of Anglesey's alumina
requirements and purchases 49% of Anglesey's aluminum output. The Company sells
its share of Anglesey's output to third parties. Power for the Anglesey alumina
smelter is supplied under an agreement which expires in 2001.
 
   
     Electrical power represents an important production cost for the Company at
the Facilities. The electricity supply contracts between the BPA and its direct
service industry customers (which consist of 15 energy intensive companies,
principally aluminum producers, including the Company) permit the BPA to
interrupt up to 25% of the amount of power which it normally supplies to such
customers. As a result of drought conditions, in January 1993 the BPA reduced
the amount of power it normally supplies to its direct service industry
customers, including the Company with respect to the Facilities. In response to
such reduction, the Company removed three reduction potlines from production
(two at the Mead smelter and one at the Tacoma smelter), and purchased
substitute power in the first quarter of 1993 at increased costs. The BPA has
notified its direct service industry customers that it intends to maintain the
interruption of 25% of the amount of power it normally provides to such
customers through February 28, 1994. Despite the temporary availability of such
power through July 1993, the Company has operated its Mead and Tacoma smelters
at the reduced operating rates introduced in January 1993, and has operated its
Trentwood fabrication facility without any curtailment of its production. The
Company currently anticipates that in 1994 it will operate the Mead and Tacoma
smelters at rates which do not exceed the current operating rates of 75% of full
capacity for such smelters. The Company cannot predict whether full power will
be provided by the BPA after February 28, 1994, or whether power will otherwise
become available at a price acceptable to the Company. The Company will continue
to assess its production levels at the Mead and Tacoma smelters in light of the
availability and cost of such power and other production costs, the market price
of primary aluminum, industry inventory levels and other industry-related and
Company-related factors.
    
 
     Effective October 1, 1993, an increase in the base rate BPA charges to its
direct service industry customers for electricity was adopted, which will
increase the Company's production costs at the Mead and Tacoma smelters by
approximately $15.0 million per year (approximately $11.3 million per year based
on the Company's current operating rate of approximately 75% of full capacity).
The rate increase generally is expected to remain in effect for two years.
 
                                       38

<PAGE>   41
 
     In the event that the BPA's revenues fall below certain levels prior to
April 1994, the BPA may impose up to a 10% surcharge on the base rate it charges
to its direct service industry customers, effective during the period from
October 1994 through October 1995 (which would increase the Company's production
costs at the Mead and Tacoma smelters by approximately $9.1 million per year
based on the Company's current operating rate of approximately 75% of full
capacity). In addition, in order to comply with certain federal laws and
regulations applicable to endangered fish species, the BPA may be required in
the future to reduce its power generation and to purchase substitute power (at
greater expense) from other sources. The foregoing factors would increase the
Company's operating expenses.
 
     The Company has developed and installed proprietary retrofit technology in
all of its smelters. This technology -- which includes the redesign of the
cathodes and anodes that conduct electricity through reduction cells, improved
"feed" systems that add alumina to the cells, and a computerized system that
controls energy flow in the cells -- enhances the Company's ability to compete
more effectively with the industry's newer smelters. The Company is actively
engaged in efforts to license this technology and sell technical and managerial
assistance to other producers worldwide, and may participate in joint ventures
or similar business partnerships which employ the Company's technical and
managerial knowledge. Pursuant to various arrangements, the Company's technology
has been installed in aluminum smelters located in West Virginia, Ohio,
Missouri, Kentucky, Sweden, Germany, India, Australia, New Zealand, Ghana, the
Commonwealth of Independent States and the United Kingdom. See "-- Research and
Development."
 
     The Company's principal primary aluminum customers consist of large trading
intermediaries and metal brokers, who resell primary aluminum to fabricated
product manufacturers, and large and small international aluminum fabricators.
In 1993, the Company sold approximately 56% of its primary aluminum production
not utilized for internal purposes to approximately 50 customers, the largest
and top five of which accounted for approximately 44% and 64% of such sales,
respectively. Marketing and sales efforts are conducted by a small staff located
at the business unit's headquarters in Pleasanton, California, and by senior
executives of the Company who often participate in the structuring of major
sales transactions. A majority of the business unit's sales are based upon
long-term relationships with metal merchants and end-users.
 
     Fabricated Products
 
       Flat-Rolled Products
 
     The Flat-Rolled Products Business Unit, the largest of the Company's
fabricated products businesses, operates the Trentwood sheet and plate mill at
Trentwood, Washington. The Trentwood facility is the Company's largest
fabricating plant and accounted for substantially more than one-half of the
Company's 1993 fabricated products shipments. The business unit supplies the
beverage container market (producing body, lid and tab stock), the aerospace
market, and the tooling plate, heat-treated alloy and common alloy coil markets,
both directly and through distributors. KACC announced in October 1993 that it
is restructuring its flat-rolled products operation at its Trentwood plant to
reduce that facility's annual operating costs. This effort is in response to
over-capacity in the aluminum rolling industry, flat demand in can stock
markets, and declining demand for aluminum products sold to customers in the
commercial aerospace industry, all of which have resulted in declining prices in
Trentwood's key markets. The Trentwood restructuring is expected to result in
annual cost savings of approximately $50.0 million after it has been fully
implemented (which is expected to occur during the next two years).
 
     The Company's flat-rolled products are sold primarily to beverage container
manufacturers located in the western United States where the Company has a
transportation advantage. Quality of products for the beverage container
industry, timeliness of delivery and price are the primary bases on which the
Company competes. The Company believes that its capital improvements at
Trentwood have enhanced the quality of its products for the beverage container
industry and the capacity and efficiency of its manufacturing operations. The
Company believes that it is one of the highest quality producers of aluminum
beverage can stock in the world.
 
     In 1993, the Flat-Rolled Products Business Unit had twenty-two foreign and
domestic can stock customers, the majority of which were beverage can
manufacturers (including seven of the eight major
 
                                       39

<PAGE>   42
 
domestic beverage can manufacturers) and the balance of which were brewers. The
largest and top five of such customers accounted for approximately 25% and 56%,
respectively, of the business unit's sales revenue. In 1993, the business unit
shipped products to over 200 customers in the aerospace, transportation and
industrial ("ATI") markets, most of which were distributors who sell to a
variety of industrial end-users. The top five customers in the ATI markets for
flat-rolled products accounted for approximately 10% of the business unit's
sales revenue. The marketing staff for the Flat-Rolled Products Business Unit is
headquartered in Pleasanton, California, and is also located at the Trentwood
facility, and sales are made directly to customers (including distributors) from
ten sales offices located throughout the United States. International customers
are served by a sales office in the Netherlands and by independent sales agents
in Asia and Latin America. See also "-- Sensitivity to Prices and Hedging
Programs -- Fabricated Products" for a discussion of demand for fabricated
products in the aerospace market.
 
       Extruded Products
 
     The Extruded Products Business Unit is headquartered in Dallas, Texas, and
operates soft alloy extrusion facilities in Los Angeles, California; Sherman,
Texas; and London, Ontario, Canada; a cathodic protection business located in
Tulsa, Oklahoma, that also extrudes both aluminum and magnesium; and rod and bar
facilities in Newark, Ohio, and Jackson, Tennessee, which produces screw machine
stock, redraw rod, forging stock and billet. Each of the soft alloy extrusion
facilities has fabricating capabilities and provides finishing services. The
Company began commercial operation of its London, Ontario, Canada facility in
the second quarter of 1992, which is designed to produce more than 50 million
pounds of extruded products annually.
 
     The Extruded Products Business Unit's major markets are in the
transportation industry, to which it provides extruded shapes for automobiles,
trucks, trailers, cabs and shipping containers, and distribution, durable goods,
defense, building and construction, ordnance, and electrical markets. In 1993,
the Extruded Products Business Unit had over 900 customers for its products, the
largest and top five of which accounted for approximately 6% and 19%,
respectively, of its sales revenue. Sales are made directly from plants as well
as marketing locations across the United States.
 
       Forgings and Castings
 
     The Forgings and Castings Business Unit operates forging facilities at
Erie, Pennsylvania, Oxnard, California, and Greenwood, South Carolina, and a
machine shop at Greenwood, South Carolina. The Forgings and Castings Business
Unit is one of the largest producers of aluminum forgings in the United States,
and is a major supplier of high quality forged parts to customers in the
automotive, commercial vehicle and ordnance markets. The high strength-to-weight
properties of forged aluminum make it particularly well suited for automotive
applications. During 1991, the Forgings and Castings Business Unit entered the
castings business by purchasing the assets of Winters Industries, which supplies
cast aluminum engine manifolds to the automobile, truck and marine markets. The
casting production facilities include two foundries and a machining facility in
Ohio.
 
     In 1993, the Forgings and Castings Business Unit had over 500 customers for
its products, the largest and top five of which accounted for approximately 20%
and 57%, respectively, of the Forgings and Casting Business Unit's sales
revenue. The Forgings and Castings Business Unit's headquarters is located in
Erie, Pennsylvania, and additional sales, marketing and engineering groups are
located in the midwestern and western United States.
 
COMPETITION
 
     Aluminum products compete in many markets with steel, copper, glass,
plastic and numerous other materials. Within the aluminum business, the Company
competes with both domestic and foreign producers of bauxite, alumina and
primary aluminum, and with domestic and foreign fabricators. The Company's
principal competitors in the sale of alumina include Alcoa of Australia, Ltd.,
Billiton International Metals B.V., Clarendon Ltd. and Pechiney S.A. In addition
to the foregoing, the Company competes with most aluminum producers in the
production of primary aluminum. Many of the Company's competitors have greater
financial resources than the Company. In addition, the Commonwealth of
Independent States has been supplying large quantities of primary aluminum to
the Western world.
 
                                       40

<PAGE>   43
 
     Primary aluminum and, to some degree, alumina are commodities with
generally standard qualities, and competition in the sale of these commodities
is based primarily upon price, quality and availability. The Company believes
that, assuming the current relationship between worldwide supply and demand for
alumina and primary aluminum does not change materially, the loss of any one of
its customers, including intermediaries, would not have a material adverse
effect on its business or operations.
 
     The Company also competes with a wide range of domestic and international
fabricators in the sale of fabricated aluminum products. Competition in the sale
of fabricated products is based upon quality, availability, price and service,
including delivery performance. The Company concentrates its fabricating
operations on selected products in which the Company has production expertise,
high quality capability, and geographic and other competitive advantages.
 
RESEARCH AND DEVELOPMENT
 
     The Company conducts research and development activities principally at
three facilities dedicated to that purpose -- the Center for Technology ("CFT")
in Pleasanton, California; the Primary Aluminum Products Division Technology
Center ("DTC") adjacent to the Mead smelter in Spokane, Washington; and the
Alumina Development Laboratory ("ADL") at the Gramercy, Louisiana refinery. Net
expenditures for Company-sponsored research and development activities were
$18.5 million in 1993, $13.5 million in 1992 and $11.4 million in 1991. The
Company's research staff totaled 160 at December 31, 1993. The Company estimates
that research and development net expenditures will be in the range of
approximately $17-$19 million per year in the 1994 period.
 
     CFT concentrates its research and development efforts on flat-rolled
products while providing specialized services to the Company's other business
units. Its activities include development of can stock products and aircraft
sheet and plate products, and process improvements directed at efficiency and
quality. In can stock, CFT works to optimize the product's metallurgy, surface
characteristics, coatings and lubrication. CFT also offers research and
development, technical services and selected proprietary technology for license
or sale to third parties. CFT is currently providing technology and technical
assistance to Samyang Metal Co. Ltd. in building an aluminum rolling mill in
Yongju, Korea. CFT also is engaged in cooperative research and development
projects with Furukawa Electric Co., Ltd., Pechiney Rhenalu and Kawasaki Steel
Corporation of Japan, with respect to the ground transportation market.
 
     DTC maintains specialized laboratories and a miniature carbon plant where
experiments with new anode and cathode technology are performed. DTC supports
the Company's primary aluminum smelters, concentrating on the development of
cost-effective technical innovations and equipment and process improvements.
Energy savings of approximately 10% have been achieved at smelters utilizing
proprietary DTC-developed technologies (which are employed in both retrofit and
new construction applications), such as improved cathode and anode design and
insulation, modified electrolyte chemistry, distributive microprocessor control
and modified cell magnetics. Other proprietary DTC retrofit technologies, such
as redesigned reduction cells, have helped the Company's older smelters achieve
competitiveness with more recently constructed facilities. The Company is
actively engaged in efforts to license this technology and sell technical and
managerial assistance to other producers worldwide. Pursuant to various
arrangements, the Company's technology has been installed in aluminum smelters
located in West Virginia, Ohio, Missouri, Kentucky, Sweden, Germany, India,
Australia, New Zealand, Ghana and the United Kingdom.
 
     The Company has entered into agreements with respect to the Krasnoyarsk
smelter located in the Commonwealth of Independent States pursuant to which the
Company has licensed certain of its technology for use in such facility and has
agreed to provide purchasing services in obtaining western-sourced technology
and equipment to be used in such facility. These agreements were entered into in
November 1990, and the services under them are expected to be completed in 1994.
In addition, the Company has entered into agreements with respect to the
Nadvoitsky smelter located in the Commonwealth of Independent States and the
Korba smelter of the Bharat Aluminum Co. Ltd. located in India pursuant to which
the Company has licensed certain of its technology for use in such facilities.
The agreements relating to the Nadvoitsky and Korba smelters were entered into
in 1993, and the services under such agreements are expected to be completed in
1995 and 1994, respectively.
 
                                       41

     ADL has developed technologies which have improved alumina refinery
efficiency. These include a high-capacity thickener process used in the
separation of alumina from bauxite slurry, plant conversion designs that enable
alumina refineries to convert from the production of fine alumina to the
preferred coarser "sandy" alumina, technology that enables refineries to process
different qualities of bauxite, and computer-aided instrumentation systems to
improve process efficiencies and energy use in alumina refineries. The Company
is actively pursuing the licensing of alumina refinery technology worldwide. The
Company's technology is in use in alumina refineries in the Americas, Australia,
India and Europe.
 
     The Company's technology sales and revenue from technical assistance to
third parties were $12.8 million in 1993, $14.1 million in 1992, and $10.9
million in 1991.
 
EMPLOYEES
 
     During 1993, the Company employed an average of 10,223 persons, compared
with an average of 10,129 employees in 1992, and 9,967 employees in 1991. At
December 31, 1993, the Company's workforce was approximately 10,029, including a
domestic workforce of 5,930, of whom 4,146 were paid at an hourly rate. Most
hourly paid domestic employees are covered by collective bargaining agreements
with various labor unions. Approximately 73% of such employees are covered by a
master agreement with the United Steelworkers of America (the "Labor Contract")
which expires on October 31, 1994. The Labor Contract covers the Company's
plants in Spokane (Trentwood and Mead), Washington; Tacoma, Washington;
Gramercy, Louisiana; and Newark, Ohio.
 
     The Labor Contract provides for floor level wages at all covered plants. In
addition, for workers covered by the Labor Contract at the Mead and Newark
plants, for any quarterly period when the average Midwest U.S. transaction price
of primary aluminum is $.54 per pound or above, a bonus payment is made. The
amount of the quarterly bonus payment changes incrementally with each full cent
change in the price of primary aluminum between $.54 per pound and $.61 per
pound, remains constant when the price is $.61 or more per pound but is below
$.74 per pound, changes incrementally again with each full cent change in the
price between $.74 per pound and $.81 per pound, and remains at the ceiling when
the price is $.81 per pound or more. Workers covered by the Labor Contract at
the Trentwood, Tacoma and Gramercy plants may receive quarterly bonus payments
based on various indices of productivity, efficiency and other aspects of
specific plant performance, as well as, in certain cases, the price of alumina
or primary aluminum. The particular quarterly bonus variable compensation
formulas currently applicable at each plant will remain applicable for the
remainder of the contract term.
 
     Pursuant to the Labor Contract, base wage rates were raised $.50 per hour
in 1990 and were raised an additional $.50 per hour effective November 1, 1993.
Each of the employees covered by the Labor Contract has received $2,000 in
lump-sum signing and special bonuses. In addition, the Company acquired in the
first quarter of 1991 up to $4,000 of preference stock held for the benefit of
approximately 80% of the employees covered by the Labor Contract, and agreed to
acquire in 1994 an additional $2,000 of such preference stock held for the
benefit of substantially the same employees. The Company also acquired in the
first quarter of 1991 up to $4,000 of preference stock which had been held for
the benefit of each of certain salaried employees. The Company considers its
employee relations to be satisfactory.
 
ENVIRONMENTAL MATTERS
 
     The Company is subject to a wide variety of Environmental Laws which
continue to be adopted and amended. The Environmental Laws regulate, among other
things, air and water emissions and discharges; the generation, storage,
treatment, transportation and disposal of solid and hazardous waste; the release
of hazardous or toxic substances, pollutants and contaminants into the
environment; and, in certain instances, the environmental condition of
industrial property prior to transfer or sale. In addition, the Company is
subject to various federal, state and local workplace health and safety laws and
regulations ("Health Laws").
 
     From time to time, the Company is subject, with respect to its current and
former operations, to fines or penalties assessed for alleged breaches of the
Environmental and Health Laws and to claims and litigation brought by federal,
state or local agencies and by private parties seeking remedial or other
enforcement action
 
                                       42

<PAGE>   45
 
under the Environmental and Health Laws or damages related to alleged injuries
to health or to the environment, including claims with respect to certain waste
disposal sites and the remediation of sites presently or formerly operated by
the Company. See "-- Legal Proceedings." The Company's Mead, Washington facility
has been listed on the National Priorities List under CERCLA. In connection with
certain of its asset sales, the Company has indemnified the purchasers of assets
with respect to certain liabilities (and associated expenses) resulting from
acts or omissions arising prior to such dispositions, including environmental
liabilities.
 
     In certain instances, the Company may be exposed to joint and several
liability for remedial action or damages to natural resources. The Company,
along with several other entities, has been named as a Potentially Responsible
Party ("PRP") for remedial costs at certain third-party sites listed on the
National Priorities List under CERCLA.
 
     While the ultimate extent of the Company's liability for pending or
potential fines, penalties, remedial costs, claims and litigation relating to
environmental and health and safety matters cannot be determined at this time
and, in light of evolving case law relating to insurance coverage for
environmental claims, management is unable to determine definitively the extent
of such coverage, management currently believes that the resolution of these
matters (even without giving effect to potential insurance recovery) should not
have a material adverse effect on the Company's consolidated financial position
or results of operations.
 
     Environmental capital spending was $12.6 million in 1993, $13.1 million in
1992 and $11.2 million in 1991. Annual operating costs for pollution control,
not including corporate overhead or depreciation, were approximately $22.4
million in 1993, $21.6 million in 1992 and $17.8 million in 1991. Legislative,
regulatory and economic uncertainties make it difficult to project future
spending for these purposes. However, the Company currently anticipates that in
the 1994-1995 period, environmental capital spending will be within the range of
approximately $7.0-$20.0 million per year, and operating costs for pollution
control will be within the range of $20.0-$22.0 million per year. These
expenditures will be made to assure compliance with applicable Environmental
Laws and are expected to include, among other things, additional "red mud"
disposal facilities and improved levees at the Gramercy, Louisiana refinery
(which are being financed by the Gramercy Bonds), bath crushing improvements,
baking furnace modernization, and improved calcining controls at the Mead,
Washington facility; new and continuing environmental projects at the Trentwood,
Washington facility; and environmental projects required under the Clean Air Act
Amendments of 1990. In addition, $7.2 million in cash expenditures in 1993, $9.6
million in 1992 and $14.0 million in 1991 were charged to previously established
reserves relating to environmental cost. Approximately $7.0 million is expected
to be charged to such reserves in 1994.
 
LEGAL PROCEEDINGS
 
     Aberdeen Pesticide Dumps Site Matter
 
     The Aberdeen Pesticide Dumps Site, listed on the Superfund National
Priorities List, is composed of five separate sites around the town of Aberdeen,
North Carolina. These sites (in the aggregate, the "Sites") include the Farm
Chemicals Site, Twin Sites, Fairway Six Site, McIver Dump Site and the Route 211
Site. The Sites are of concern to the United States Environmental Protection
Agency (the "EPA") because of their past use as either pesticide formulation
facilities or pesticide disposal areas from approximately the mid-1930's through
the late 1980's.
 
     The United States originally filed a cost recovery complaint (as amended,
the "Complaint") in the United States District Court for the Middle District of
North Carolina, Rockingham Division, No. C-89-231-R, against five defendants on
March 31, 1989, and subsequently amended its complaint to add another ten
defendants on February 6, 1991, and another four defendants on August 1, 1991.
The Company and KACC were not defendants named in the Complaint. The Complaint
seeks reimbursement for past and future response costs and a determination of
liability of the defendants under Section 107 of CERCLA.
 
     On or about October 2, 1991, KACC, along with approximately seventeen other
parties, was served with third party complaints from four of the defendants
named in the Complaint (the "Third Party Plaintiffs")
 
                                       43

<PAGE>   46
 
alleging claims arising under various theories of contribution and indemnity. On
October 22, 1992, the United States filed a motion for leave to file an amended
complaint naming KACC as a first party defendant in its cost recovery action. On
February 16, 1993, the court granted that motion.
 
     The EPA has performed a Remedial Investigation/Feasibility Study and issued
a Record of Decision ("ROD") dated September 30, 1991, for the Sites. The major
remedy selected for the five Sites in the ROD consisted of excavation of
contaminated soil, treatment of the contaminated soil at a single location
utilizing thermal treatment, and placement of the treated material back into the
areas of excavation. The estimated cost of such remedy for the five Sites is
approximately $32 million. Other possible remedies described in the ROD included
on-site incineration and on-site ash disposal at an estimated cost of
approximately $53 million, and off-site incineration and disposal at an
estimated cost of approximately $222 million. The Company understands that the
EPA is also investigating contamination of groundwater at the Sites. The EPA has
stated that it has incurred past costs at the Sites in the range of $7.5-$8
million as of February 9, 1993, and alleges that response costs will continue to
be incurred in the future.
 
     On May 20, 1993, the EPA issued three unilateral Administrative Orders
under Section 106(a) of CERCLA ordering the Respondents, including KACC, to
perform the remedial design and remedial action described in the ROD for the
Farm Chemicals Site (EPA Docket No. 93-13-C), Twin Sites (EPA Docket No.
93-14-C) and Fairway Six Site (EPA Docket No. 93-15-C). The estimated cost as
set forth in the ROD for the remedial action at the three sites is approximately
$27 million. In additional to KACC, Respondents named in the Administrative
Orders for all three sites include J. M. Taylor, Grower Service Corporation, E.
I. DuPont de Nemours & Co., Olin Corporation, UCI Holdings, Inc., PPG
Industries, Inc., and Union Carbide Corporation. Ciba-Geigy Corporation,
Hercules, Inc., Mobil Oil Corporation, Shell Oil Company, The Boots Company
(USA), Inc., Nor-Am Chemical Co., George D. Anderson, Farm Chemicals, Inc.,
Partners In The Pits, Ltd., Dan F. Maples, Pits Management Corp., Maples Golf
Construction, Inc., Yadco of Pinehurst, Inc. and Robert Trent Jones are named as
Respondents for one or two of the Sites.
 
     The Company has entered into an Agreement in Principle with certain of the
respondents to participate jointly in responding to the Administrative Orders,
to share costs incurred on an interim basis, and to seek to reach a final
allocation of costs through agreement or to allow such final allocation and
determination of liability to be made by the United States District Court. A
definitive PRP Participation Agreement is awaiting execution by the group. By
letter dated July 6, 1993, the Company notified the EPA of its ongoing
participation with such group of respondents which, as a group, are intending to
comply with the Administrative Orders to the extent consistent with applicable
law.
 
   
     By letters dated December 30, 1993, the EPA notified KACC of its potential
liability for, and requested that KACC, along with certain other companies,
undertake or agree to finance, groundwater remediation at certain of the sites.
With respect to the Farm Chemicals and Twin Sites, in addition to KACC, the EPA
issued such letters to J.M. Taylor, Grower Services Corporation, Farm Chemicals,
Inc., E.I. DuPont de Nemours and Company, Olin Corporation, UCI Holdings, Inc.,
Union Carbide Corporation, Miles, Inc., Mobil Oil Corporation, Shell Oil
Company, Hercules, Inc., The Boots Company (USA), Inc., Nor-Am Chemical Company,
and Ciba-Geigy Corporation. With respect to the Fairway Six Site, in addition to
KACC, the EPA issued such letters to J.M. Taylor, G.D. Anderson, Grower Service
Corporation, Partners in Pits, Dan Maples, Pits Management Corporation, Maples
Golf Construction, Inc., Yadco of Pinehurst, Inc., Robert Trent Jones, E.I.
DuPont de Nemours and Company, Olin Corporation, UCI Holdings, Inc., Union
Carbide Corporation, Miles, Inc., Ciba-Geigy Corporation and Hercules, Inc. The
ROD-selected remedy for the groundwater remediation selected by EPA includes
extraction, on-site treatment by coagulation/flocculation/precipitation, air
stripping, GAC absorption, and discharge on site for the Farm Chemicals/Twin
Sites and extraction, on-site treatment by GAC absorption and discharge on-site
for the Fairway Six Site. The EPA has estimated the total present worth cost,
including thirty years of operation and maintenance, at $11,849,757.
    
 
   
     KACC, along with other notified parties, plans to meet with representatives
of the EPA to discuss whether an agreement to perform this remediation is
possible.
    
 
                                       44

<PAGE>   47
 
     Based upon the information presently available to it, the Company is unable
to determine whether KACC has any liability with respect to any of the Sites or,
if there is any liability, the amount thereof. Two Government witnesses have
testified that KACC acquired pesticide products from the operator of the
formulation site over a two to three year period. The Company has been unable to
confirm the accuracy of this testimony.
 
     United States of America v. Kaiser Aluminum & Chemical Corporation
 
     On February 8, 1989, a civil action was filed by the United States
Department of Justice at the request of the EPA against the Company in the
United States District Court for the Eastern District of Washington, Case Number
C-89-106-CLQ. The complaint alleged that emissions from certain stacks at the
Company's Trentwood facility in Spokane, Washington intermittently violated the
opacity standard contained in the Washington State Implementation Plan ("SIP"),
approved by the EPA under the federal Clean Air Act. The complaint sought
injunctive relief, including an order that the Company take all necessary action
to achieve compliance with the Washington SIP opacity limit and the assessment
of civil penalties of not more than $25,000 per day.
 
     In the course of the litigation, questions arose as to whether the
observers who recorded the alleged exceedances were qualified under the
Washington SIP to read opacity. In July 1990, the Company and the Department of
Justice agreed to a voluntary dismissal of the action. At that time, however,
the EPA had arranged for increased surveillance of the Trentwood facility by
consultants and the EPA's personnel. From May 1990 through May 1991, these
observers recorded approximately 130 alleged exceedances of the SIP opacity
rule. Justice Department representatives have stated their intent to file a
second lawsuit against the Company based on the opacity observations recorded
during that period.
 
   
     The second lawsuit has not yet been filed. Instead, the Company has entered
into negotiations with the EPA to resolve the claims against the Company through
a consent decree. Although the EPA and the Company have made substantial
progress in negotiating the terms of the consent decree, key issues remain to be
resolved. Anticipated elements of any settlement would include a commitment by
the Company to improve the emission control equipment at the Trentwood facility
and a civil penalty assessment against the Company, in an amount to be
determined.
    
 
     As of the date of this Prospectus, the Company cannot predict the
likelihood that the EPA and the Company will reach agreement upon the terms of a
consent decree. In the event that the negotiations are not successful, the
matter likely would be resolved in federal court.
 
     Catellus Development Corporation v. Kaiser Aluminum & Chemical Corporation
     and James L. Ferry & Son, Inc.
 
     On January 7, 1991, the City of Richmond, et al. (the "Plaintiffs") filed a
Second Amended Complaint for Damages and Declaratory Relief against the United
States of America, the United States Maritime Administration and Santa Fe Land
Corporation (now known as Catellus Development Corporation ("Catellus"))
(collectively, the "Defendants") alleging, among other things, that the
Defendants caused or allowed hazardous substances, pollutants, contaminants,
debris and other solid wastes to be discharged, deposited, disposed of or
released on certain property located in Richmond, California (the "Property")
formerly owned by Catellus and leased to (i) the Company for the purpose of
shipbuilding activities conducted by the Company on behalf of the United States
during World War II, and (ii) subsequent tenants thereafter. Plaintiffs allege,
among other things, that (i) the Defendants are jointly and severally liable for
response costs and natural resources damages under CERCLA, (ii) Defendant United
States of America is liable on grounds of negligence for damages under the
Federal Tort Claims Act, and (iii) Defendant Catellus is strictly liable and on
grounds of negligence for such discharge, deposit, disposal or release. Certain
of the Plaintiffs have alleged that they had incurred or expect to incur costs
and damages in the amount of approximately $49 million, in the aggregate.
 
     On or about September 23, 1992, the Plaintiffs filed a Third Amended
Complaint, alleging, among other things, that (i) the Defendants are jointly and
severally liable for response costs, declaratory relief and natural
 
                                       45

<PAGE>   48
 
resources damages under CERCLA; (ii) Defendant United States of America is
liable on grounds of negligence, continuing trespass and continuing nuisance for
damages under the Federal Tort Claims Act; (iii) Defendant Catellus is strictly
liable on grounds of continuing nuisance, continuing trespass and negligence for
such discharge, deposit, disposal or release; (iv) Catellus is liable to
indemnify Plaintiffs; and (v) Catellus is liable for fraudulent concealment of
the alleged contamination.
 
     On February 20, 1991, Catellus filed a third party complaint (the "Third
Party Complaint") against the Company and James L. Ferry & Son, Inc. ("Ferry")
in the United States District Court for the Northern District of California,
Case No. C-89-2935 DLJ. The Third Party Complaint was served on the Company as
of April 12, 1991. The Third Party Complaint alleges that, if the allegations of
the Plaintiffs are true, then the Company and Ferry (which is alleged to have
performed certain excavation activities on the Property and, as a result
thereof, to have released contaminants on the Property and to have arranged for
the transportation, treatment and disposal of such contaminants) are liable for
Catellus' response costs and damages under CERCLA and damages under other
theories of negligence and nuisance and, in the case of the Company, waste.
Catellus seeks (i) contribution from the Company and Ferry, jointly and
severally, for its costs and damages pursuant to CERCLA, (ii) indemnity from the
Company and Ferry for any liability or judgment imposed upon it, (iii) indemnity
from the Company and Ferry for reasonable attorneys' fees and costs incurred by
it, (iv) damages for the injury to its interest in the Property, and (v) treble
damages from the Company pursuant to California Code of Civil Procedure Section
732. On June 4, 1991, Catellus served on the Company a first amended third party
complaint which alleges, in addition to the allegations of the Third Party
Complaint, that the Company and/or a predecessor in interest to the Company is
also liable for Catellus' damages, if any, on the basis of alleged contractual
indemnities contained in certain former leases of the Property.
 
     The Third Party Complaint was amended on or about October 26, 1992. The
amended Third Party Complaint alleges that, if the allegations of the Plaintiffs
are true, then the Company and Ferry (which is alleged to have performed certain
excavation activities on the Property and, as a result thereof, to have released
contaminants on the Property and to have arranged for the transportation,
treatment and disposal of such contaminants) are liable for (i) Catellus'
response costs and natural resources damage under CERCLA; (ii) damages under
theories of negligence, trespass and nuisance; (iii) indemnity (equitable and
contractual); and (iv) attorneys fees under California Code of Civil Procedure
Section 1021.6.
 
   
     By letter dated October 26, 1992, counsel for certain underwriters at
Lloyd's London and certain London Market insurance companies ("London Insurers")
advised that the London Insurers agreed to reimburse the Company for defense
expenses in the third party action filed by Catellus, subject to a full
reservation of rights.
    
 
     The Plaintiffs filed a motion for leave to file a Third Amended Complaint
which would have added the Company as a first party defendant. This motion was
denied. On October 26, 1992, the Plaintiffs served a separate Complaint against
the Company for damages and declaratory relief. The claims asserted by the
Plaintiffs are for (i) recovery of costs, natural resources damages and
declaratory relief under CERCLA; (ii) damages for injury to the Property arising
from negligence; (iii) damages under a theory of strict liability; (iv)
continuing nuisance and continuing trespass; (v) equitable indemnity; (vi)
response costs incurred by the Richmond Redevelopment Agency under California
Health & Safety Code Section 33459.4; and (vii) declaratory relief on the state
claims. This matter has been tendered to the London Insurers.
 
     Picketville Road Landfill Matter
 
     On July 1, 1991, the EPA served on the Company and thirteen other PRPs a
Unilateral Administrative Order For Remedial Design and Remedial Action (the
"Order") at the Picketville Road Landfill site in Jacksonville, Florida. The EPA
seeks remedial design and remedial action pursuant to CERCLA from some, but
apparently not all, PRPs based upon a Record of Decision outlining remedial
cleanup measures to be undertaken at the site adopted by the EPA on September
28, 1990. The site was operated as a municipal and industrial waste landfill
from 1968 to 1977 by the City of Jacksonville. The Company was first notified by
the EPA on January 17, 1991, that wastes from one of the Company's plants may
have been transported to and deposited in the site. In its Record of Decision,
the EPA estimated that the total capital, operations and
 
                                       46

<PAGE>   49
 
   
maintenance costs of its elected remedy for the site would be approximately $9.9
million. There can be no assurance that such costs will not exceed such
estimated amount. In addition, the EPA has reserved the right to seek recovery
of its costs incurred relating to the Order, including, but not limited to,
reimbursement of the EPA's cost of response. Through negotiations with the EPA
and other PRPs, the Company has reached an agreement with such PRPs under which
the Company will fund $146,700 of the cost of the remedial action (unless
remedial costs exceed $19 million, in which event the settlement agreement will
be re-opened). The implementation of the foregoing agreement is subject to
continuing discussion among the EPA, the other PRPs and the Company.
    
 
     Asbestos-related Litigation
 
   
     The Company is a defendant in a number of lawsuits in which the plaintiffs
allege that certain of their injuries were caused by exposure to asbestos
during, and as a result of, their employment with the Company or to products
containing asbestos produced or sold by the Company. The number of such lawsuits
instituted against the Company increased substantially in 1993 and management
believes the number of such lawsuits will continue to increase at a greater
annualized rate than in prior years. In connection with such litigation, the
Company made cash payments (for settlement and other related costs) during 1993,
1992 and 1991, in the amounts of $7.0 million, $7.1 million and $6.1 million,
respectively. Based upon prior experience, the Company estimates future cash
payments in connection with such litigation of approximately $8.0 million to
$12.0 million per year for the years 1994 through 1998, and an aggregate of
approximately $85.0 million thereafter (through 2007). While the ultimate extent
of the Company's liability for asbestos-related claims cannot be determined at
this time, management currently believes that potential insurance recoveries
should be adequate to pay substantially all of such claims, and that, as a
result thereof, the resolution of these matters should not have a material
adverse effect on the Company's consolidated financial position or results of
operations.
    
 
     Various other lawsuits and claims are pending against the Company.
Management believes that resolution of the lawsuits and claims made against the
Company, including the matters discussed above, will not have a material adverse
effect on the Company's consolidated financial position.
 
PROPERTIES
 
     The Company owns in fee or leases all the real estate and facilities used
in connection with its business. Plants and equipment and other facilities are
generally in good condition and suitable for their intended uses, subject to
changing environmental requirements. Although the Company's domestic aluminum
smelters and alumina facility were initially designed early in the Company's
history, they have been modified frequently over the years to incorporate
technological advances in order to improve efficiency, increase capacity and
achieve energy savings. The Company believes that its domestic plants are cost
competitive on an international basis. Due to the Company's variable cost
structure, the plants' operating costs are relatively lower in periods of low
primary aluminum prices and relatively higher in periods of high primary
aluminum prices.
 
     Obligations under the Credit Agreement are secured by, among other things,
mortgages on the Company's plants located in Spokane (the Trentwood and Mead
plants) and Tacoma, Washington; Gramercy, Louisiana; Erie, Pennsylvania; Newark,
Ohio; and Sherman, Texas. The New Credit Agreement will not be secured by the
Company's Gramercy, Louisiana plant.
 
OTHER MATTERS
 
     On February 7, 1989, the Company sold aluminum production facilities at
Ravenswood, West Virginia (the "Ravenswood Works") and Bedford, Indiana and a
data center at Columbus, Ohio. The sales price for the three facilities was
approximately $256 million, including approximately $168 million in cash and the
assumption by the buyer of certain liabilities. Among the liabilities the buyer
and its pension plan assumed were pension liabilities relating to former
employees of the Company represented by the United Steelworkers of America
("USWA") who were employed by the buyer at the Ravenswood Works and the Bedford
facility
 
                                       47

<PAGE>   50
 
at the sale date (the "Former Employees"). The projected benefit obligation
relating to such assumed pension liabilities was calculated at such time to be
approximately $77.6 million. The buyer agreed to certain restrictions on its
activities designed to help assure that it would meet its assumed obligations.
The Company retained liability for pension, retiree health and life insurance
coverage with respect to Ravenswood Works employees who retired from the Company
prior to the sale date.
 
     The Company agreed with the USWA that in the event of a permanent shutdown
of the Ravenswood Works prior to February 7, 1994, the Former Employees would
receive from the owner of the Ravenswood Works, the Pension Benefit Guaranty
Corporation, the Company and/or a pension plan maintained by the Company, the
pension benefits accrued as of the sale date subject to certain limited
exceptions. The Company also agreed with the USWA that in the event of such a
shutdown, such Former Employees, if otherwise eligible, would receive retiree
health coverage, subject to a monthly premium, and a portion of their life
insurance coverage. The Company has not calculated the costs which would be
necessary to provide the retiree health and life insurance coverage, but such
costs are believed to be smaller than the amount of the pension liabilities
assumed by the buyer.
 
     The Department of Labor ("DOL"), which has enforcement powers under the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), in
October 1991, initiated a review of the transfer of the pension liabilities and
the related assets from the Company plan to the buyer and its pension plan. The
Company has assisted the DOL with its review and believes that its agreements
and actions in connection with the sale and the actions of the Company plan
fiduciaries were in full compliance with ERISA.

     On April 2, 1993, the Compensation Committee recommended to the Board of
Directors the adoption of the Kaiser 1993 Omnibus Stock Incentive Plan (the
"Plan"). On April 6, 1993, the Board of Directors
 
                                       54

<PAGE>   57
 
adopted the Plan, subject to approval by the stockholders of the Company and
KACC. The stockholders of both the Company and KACC approved the Plan at their
1993 Annual Meetings.
 
     The Company and KACC currently have identical Boards of Directors and
identical Compensation Committee memberships. Accordingly, their respective
Compensation Committees are referred to jointly in this section as the
"Committee." The Plan is the Company's first stock-based incentive plan since
KACC's 1979 Stock Option Plan, which expired on December 31, 1988. The Plan is
jointly sponsored by the Company and KACC.
 
     The description of the Plan herein is qualified in its entirety by the
provisions of the Plan, a copy of which has been filed with the Commission.
 
  Long-Term Incentive Compensation Background
 
     Effective as of January 1, 1989, the Company and KACC adopted an unfunded
long-term incentive plan (as amended, the "LTIP"). Effective as of January 1,
1990, KACC adopted an unfunded middle management long-term incentive plan (the
"Mid-Management Plan"). No employee participates in both plans. Both plans are
linked to certain measurements of corporate net income.
 
     During 1992, the senior managements of the Company and KACC and the
Committee determined that the continued utilization of the LTIP and
Mid-Management Plan might not be in the best interest of the corporations. They
observed that virtually all benefits under the LTIP had been earned and that the
Mid-Management Plan was being viewed as an annual, rather than longer term,
incentive. Moreover, they observed that the Company's stock had become publicly
traded since those plans were adopted. For these and other reasons the Committee
determined that it would be appropriate to design a new stock-based long-term
incentive plan.
 
  Compensation Committee Initiation of the Plan and Initial Grants
 
     At its meeting held on December 2, 1992, the Committee directed the
preparation of a flexible but stock-based incentive plan for joint sponsorship
by the Company and KACC. The Committee determined not to make year-end 1992
grants to participants under either the LTIP or the Mid-Management Plan and
indicated that, although such plans were not being terminated, they expected to
make future long-term incentive grants to certain employees under a stock-based
plan.
 
     In addition, the Committee determined to provide a one-time opportunity for
participants in the LTIP to elect to receive payment of their LTIP account
balances, as of December 31, 1992, as follows:
 
          (i) Amounts earned and vested would be paid half in cash and half in
     restricted shares of Common Stock. Ninety-five percent of the earned and
     vested amounts would be paid on or prior to December 31, 1992, with the
     remainder to be paid on or about April 10, 1993. The portion payable in
     restricted shares of Common Stock would be divided by the average closing
     price for the stock for December 1992 through the latest practical date to
     determine the number of shares granted. As implemented, the average
     December price of $8.539 per share (through December 28, 1992) was
     utilized. The portion payable in cash would be reduced by 1992 bonuses paid
     to recipients and by appropriate tax withholdings.
 
          (ii) Amounts earned and unvested as of December 31, 1992 under the
     LTIP would be paid in options or shares of restricted stock under the Plan
     following its implementation. Restrictions would be removed or options
     would vest at the rate of 25% each December for four (4) years.
 
          (iii) Amounts unearned and unvested as of December 31, 1992 under the
     LTIP would be paid in options or shares of restricted stock under the Plan
     following its implementation. Restrictions would be removed or options
     would vest as to 50% thereof in each of December 1995 and December 1996.
 
     The payments made in accordance with item (i) above were separate and apart
from the Plan and are reflected in column (h) of the Summary Compensation Table
set forth hereafter. The grants made in accordance with items (ii) and (iii)
above are referred to in the Plan as the Initial Grants and are reflected in
column (f) of the Summary Compensation Table.

     Six participants in the LTIP, constituting all of the participants in the
LTIP then employed by KACC other than Messrs. John M. Seidl (former Chairman of
the Board and Chief Executive Officer of the Company until December 31, 1992)
and Hutchcraft (former Chairman of the Board and Chief Executive Officer of the
Company until December 31, 1993), timely made elections to receive the December
1992 restricted stock and cash distribution and the Initial Grants under the
Plan in lieu of the LTIP benefits attributable to their accounts at year end
1992. As a result of their elections, Messrs. La Duc and Bonn each received as
to their 95% payment described in item (i) above, 13,145 shares of restricted
Common Stock. Mr. La Duc received cash in the amount of $13,159, and Mr. Bonn's
cash account was a negative $1,489 which he paid to the Company. The remaining
in lieu distributions were made to these individuals on or about April 10, 1993
and amounted to $1,384 and 772 shares to Mr. La Duc and $690 and 772 shares to
Mr. Bonn. The Initial Grants relating to items (ii) and (iii) above are an
integral part of the Plan. The information shown below in the New Plan Benefits
Table, except with respect to Mr. Haymaker, represents the Initial Grants. An
aggregate of 764,096 shares of restricted Common Stock were awarded as the
Initial Grants, including 167,346 shares each to Messrs. La Duc and Bonn.

  General Provisions
 
     The Plan is administered by the Committee. It is the intention of the Board
of Directors that the Plan be formulated, adopted and administered in a manner
which allows for transactions under it to be exempt employee benefit
transactions under Rule 16b-3 of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). Accordingly, no person shall serve on the Committee who
has received any grant or award under the Plan within one year prior to his or
her appointment nor shall any person receive a grant or award under the Plan
while a member of the Committee. The Committee may select participants for
awards, in addition to the Initial Grants under the Plan, from among those
employees of the Company recommended by the Chief Executive Officer of the
Company who are, in the opinion of the Committee, key employees in a position to
contribute materially to the Company's continued growth and development and to
its long-term success. It is expected that approximately 80 employees will
participate in the Plan within the first two (2)
 
                                       56

<PAGE>   59
 
years of its duration, but such participation has not been determined and is
subject to the discretion of the Committee.
 
     The Committee has discretion to make awards under the Plan. In making
awards, the Committee has flexibility in choosing from a variety of stock-based
incentive alternatives. The Plan allows for the grant of incentive stock options
("ISOs"), nonstatutory stock options, stock appreciation rights ("SARs"),
performance units, performance shares, restricted stock and unrestricted stock;
however, it is not contemplated that any participant will receive awards from
all categories available under the Plan. Up to 2,500,000 shares of the Common
Stock are reserved for awards or for payment of rights granted under the Plan
(subject to adjustment in the event of certain changes in the capitalization of
the Company). Of that amount, the Initial Grants comprise 764,096 shares of
Common Stock. Payments under the Plan for other than direct awards of stock may
be made in cash, in stock or partly in each, at the discretion of the Committee.
If any award terminates or lapses prior to the expiration or earlier termination
of the Plan, the shares of Common Stock subject to the award will be available
again for award under the Plan (except in the case of a stock option as to which
a related SAR has been exercised).
 
     The Plan became effective as of December 1992 upon stockholder approval and
will expire on December 31, 2002. Awards made under the Plan prior to its
termination shall remain in effect until they shall have been exercised,
satisfied or terminated as set forth in the Plan. The Board of Directors may
suspend or terminate the Plan at any time prior to its expiration. Any amendment
increasing the aggregate number of shares of Common Stock which may be issued
pursuant to ISOs or making certain other material changes shall require
stockholder approval. However, no plan amendment may adversely impact a
previously granted award made under the Plan without consent of the grantee.
 
     Awards under the Plan (other than direct grants of stock or stock obtained
as payment through exercise of a Plan award) may not be transferred except by
will or the laws of descent and distribution. Stock obtained under the Plan may
be subject to restrictions and recipients will be subject to reporting and
disposition restrictions under Section 16 of the Exchange Act and related
insider trading laws.
 
  Stock Options
 
     The Committee may grant options to purchase shares of Common Stock. Such
options may be nonstatutory or nonqualified stock options and ISOs pursuant to
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").
 
     The option price for any option may not be less than the par value of the
Common Stock and ISOs granted under the Plan may not utilize an exercise price
which is less than the fair market value of the Common Stock on the date of the
grant. The option price may be paid in cash, in previously acquired Common Stock
held for at least six (6) months and with a fair market value on the date of
exercise equal to the option price, or by combination of cash and Common Stock.
The Committee may also approve other forms of payment. Options may not be
exercised sooner than one year or more than ten years from the date of grant.
 
  Stock Appreciation Rights
 
     The Committee may grant stock appreciation rights in conjunction with, or
apart from, stock options. An SAR entitles the grantee to receive a payment from
the Company equal to the excess of the fair market value of a share of Common
Stock at the date of exercise over a specified price fixed by the Committee. The
Committee may establish a maximum appreciation value when granting SARs. Payment
for SARs may be made in cash, Common Stock, or a combination of both, at the
discretion of the Committee. SARs may not be exercised sooner than one year or
more than ten years from the date of grant.
 
  Restricted Stock
 
     The Committee may grant shares of restricted Common Stock under the Plan.
The Committee may make the grant of restricted Common Stock subject to various
conditions including the participant remaining
 
                                       57

<PAGE>   60
 
employed by the Company for a number of years. Participants holding shares of
restricted stock may exercise full voting rights with respect to those shares
but shall not be entitled to receive dividends and other distributions paid, if
any, with respect to those shares during the period of restriction. A holder of
restricted stock may not sell or otherwise transfer the Common Stock until the
restrictions have lapsed or have been removed.
 
  Performance Units and Performance Shares
 
     The Committee may grant performance units and performance shares under the
Plan. In such event, the Committee will establish a performance period over
which corporate, business unit, or individual performance goals set by the
Committee will be measured. At the end of the performance period, the
performance units or performance shares will be paid out at their initial
established values, increased or decreased, as the case may be, based upon
performance above or below target levels. Payment may be made in cash, Common
Stock or a combination thereof as determined by the Committee. Payment may be
made in a lump sum or in installments at the Committee's discretion. In the
event payment is deferred, interest or dividend equivalents may be paid to
participants.
 
  Unrestricted Stock
 
     Unrestricted shares of Common Stock also may be awarded under the Plan as
well as upon the exercise of stock options, in connection with distributions due
on the exercise of stock appreciation rights or as payment on performance units
or performance shares.
 
  Rights to Grants Upon Termination of Employment
 
     In the event a participant's employment is terminated by reason of death,
disability, or retirement, vested options or other vested rights under the Plan
may be exercised within twelve months of termination (three years in the event
of retirement), or the remaining term of the option or right, whichever is
shorter. If employment is terminated for any other reason, options or rights may
be exercised for three months, or the remaining term of the option or right,
whichever is shorter, except that participants who are terminated for cause
immediately forfeit all exercise rights. In the event a participant dies,
becomes disabled or retires after having reached normal retirement age for
pension purposes, a portion of such person's granted shares of restricted stock
will become free of restrictions, and a portion of such person's granted stock
options, SARs, performance units or performance shares shall vest. Such portion
shall be equal to the number of shares subject to such grants multiplied by the
number of full months elapsed between the date of grant and the date of death,
disability or retirement, divided by the number of full months of the period for
which such grants were to have been restricted or to have remained unvested. The
remaining portion of such grants shall be forfeited. In the event of retirement
before normal retirement age, all such grants shall continue to be subject to
their respective conditions, vesting schedules and restrictions, including any
requiring continued employment. In the event a participant's employment is
terminated involuntarily, other than for cause, the Committee may, in its
discretion, waive any applicable forfeiture, vesting requirements or
restrictions as it deems appropriate.

 (1) Pursuant to the transitional rules effective October 21, 1992, these
     amounts are excluded for the Company's 1991 and 1990 fiscal years.
 
 (2) Excludes perquisites and other personal benefits because the aggregate
     amount of such compensation is the lesser of either $50,000 or 10% of the
     total of annual salary and bonus reported for the named executive officer.
 
 (3) Includes payment of $38,077 representing accrued vacation not taken upon
     his resignation on December 31, 1992, in addition to his base salary of
     $495,000.
 
 (4) Includes moving related items of $30,111, $3,969 and $76,684 for Messrs.
     Seidl, La Duc and Bonn, respectively.
 
 (5) Includes $5,711, $8,000, $4,500 and $4,200 under the Kaiser Savings Plan
     (as defined below) to Messrs. Seidl, Hutchcraft, La Duc and Bonn,
     respectively. Also includes $3,423 credited to Mr. Hutchcraft under the
     Kaiser Supplemental Benefits Plan described below. Includes $15,364 loan
     forgiveness granted to Mr. Bonn in March 1992.
 
 (6) Pursuant to 1991 amendments, LTIP participants were permitted to elect an
     accelerated payment option pursuant to which they could receive in December
     1991 and April 1992 amounts approximating 95% and 5% respectively of the
     vested portion of their LTIP account balances (excluding bonuses previously
     paid), subject to certain maximum dollar limitations. Without such
     accelerated payment option and subject to certain reductions and

 (7) Mr. Pierno receives his compensation from MAXXAM; however the Company
     reimburses MAXXAM for certain allocable costs associated with the
     performance of services for the Company by such executive officer. The
     table reflects such officer's total compensation rather than an allocated
     part of such compensation. Mr. Pierno's compensation for 1991 and 1990 is
     not included since he was not an executive officer of the Company at any
     time during such years.
 
 (8) Pursuant to Mr. Pierno's employment agreement, his personal loans from
     MAXXAM outstanding on the date of such agreement are forgiven at the rate
     of $15,000 per year. This amount is included as part of his bonus
     compensation. See "Certain Transactions" for a discussion of such personal
     loans.
 
 (9) Represent matching contributions by MAXXAM under the MAXXAM 401-K savings
     plan of $4,782, and $45,341 accrued in respect of MAXXAM's revised capital
     accumulation plan pursuant to which, in general, benefits vesting 10%
     annually are payable upon termination of employment with MAXXAM.

(11) At the end of fiscal year 1992, Messrs. Bonn and La Duc each owned 13,145
     shares of restricted common stock of the Company valued at approximately
     $112,245.
 
(12) Represents SARs Mr. La Duc received from MAXXAM with respect to MAXXAM's
     common stock.
 
(13) See "-- The Kaiser 1993 Omnibus Stock Incentive Plan" regarding the
     election by LTIP participants to receive payment of their LTIP account
     balances. Without such election opportunity and subject to certain
     reductions and limitations, participants were generally entitled to receive
     the vested portion of their LTIP account balances on the earlier to occur
     of (a) termination of their employment, (b) termination of the LTIP if
     prior to December 31, 1996, or (c) April 10, 1997. Pursuant to such
     election, these amounts were paid half in cash and half in restricted
     shares of Common Stock of the Company.

     The foregoing table shows estimated annual retirement benefits payable
under the terms of the Kaiser Retirement Plan to participants with the indicated
years of credited service without reduction for the limitations imposed by the
Code on qualified plans and before adjustment for the social security offset.
KACC has adopted a Supplemental Benefits Plan under which certain participants
in the Kaiser Retirement Plan will receive the benefits described in the summary
of the Supplemental Benefits Plan set forth below. The estimated annual
retirement benefits shown are based upon the assumptions that current Kaiser
Retirement Plan provisions remain in effect, that the participant retires at age
65, and that the retiree receives payments based on a straight life annuity for
his lifetime.
 
     Messrs. Seidl, Hutchcraft, La Duc and Bonn had 3.9, 36.8, 23.3 and 25.5
years of credited service, respectively, on December 31, 1992. Monthly
retirement benefits, except for certain minimum benefits, are determined by
multiplying years of credited service (not in excess of 40) by the difference
between 1.50% of average monthly compensation for the highest base period (of
36, 48 or 60 consecutive months, depending upon compensation level) in the last
10 years of employment and 1.25% of monthly primary social security benefits.
 
                                       61

<PAGE>   64
 
     The compensation covered by the Kaiser Retirement Plan includes base salary
and bonus payments. No named executive officer had compensation covered by the
Kaiser Retirement Plan which differed by more than 10% from that set forth in
the Summary Compensation Table (column (c) plus column (d) thereof).
 
     Participants are entitled to retire and receive pension benefits, unreduced
for age, upon reaching age 62 or after 30 years of credited service. Full early
pension benefits (without adjustment for social security offset prior to age 62)
are payable to participants who are at least 55 years of age and have completed
10 or more years of pension service (or whose age and years of pension service
total 70) and who have been terminated by KACC or an affiliate for reasons of
job elimination or partial disability. Participants electing to retire prior to
age 62 who are at least 55 years of age and have completed 10 or more years of
pension service (or whose age and years of pension service total at least 70)
may receive pension benefits, unreduced for age, payable at age 62 or reduced
benefits payable earlier. Participants who terminate their employment after five
years or more of pension service, or after age 55 but prior to age 62, are
entitled to pension benefits, unreduced for age, commencing at age 62 or
actuarially reduced benefits payable earlier. For participants with five or more
years of pension service or who have reached age 55 and who die, the Kaiser
Retirement Plan provides a pension to their eligible surviving spouses. Upon
retirement, participants may elect among several payment alternatives including,
for most types of retirement, a lump-sum payment.
 
  Kaiser Supplemental Benefits Plan
 
     KACC maintains an unfunded, non-qualified Supplemental Benefits Plan (the
"Kaiser Supplemental Benefits Plan"), the purpose of which is to restore
benefits which would otherwise be paid from the Kaiser Retirement Plan or the
Supplemental Savings and Retirement Plan, a qualified Section 401(k) plan (the
"Kaiser Savings Plan"), were it not for the limitations imposed by the Code.
Participation in the Kaiser Supplemental Benefits Plan includes all employees of
KACC and its subsidiaries whose benefits under the Kaiser Retirement Plan and
Kaiser Savings Plan are likely to exceed the maximum dollar limitations imposed
by the Code. Eligible participants are entitled to receive the equivalent of the
Kaiser Retirement Plan and Kaiser Savings Plan benefits which they may be
prevented from receiving under those plans because of Code limitations.
 
EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS
 
     Until his resignation on December 31, 1992, Mr. Seidl held the positions of
Chairman and Chief Executive Officer of the Company and KACC. He was employed
pursuant to an employment agreement which commenced February 1, 1989 and
provided for an annual salary of $450,000, or such higher rate as might be
mutually agreed to by Mr. Seidl, the Company and KACC. Mr. Seidl was eligible to
participate in the employee benefit plans and fringe benefit programs maintained
by the Company and KACC as from time to time in effect applicable to senior
executives of the Company and KACC; provided that Mr. Seidl was eligible to
participate in any bonus program maintained by the Company or KACC only to the
extent participants in the LTIP were also eligible for such bonus program
participation. In general, Mr. Seidl was entitled to participate in the LTIP in
accordance with the terms of the LTIP. In light of his resignation, Mr. Seidl
and KACC entered into an agreement on December 23, 1992, pursuant to which Mr.
Seidl received $1,000,000 on or before December 31, 1992 (the "December
Payment") in payment of benefits otherwise due him on or before April 10, 1993.
In consideration thereof, Mr. Seidl agreed that the payment of benefits
otherwise due him on or before April 10, 1993 would be reduced by $1,000,000
plus an amount equal to interest on $1,000,000 from the date of the December
Payment to April 10, 1993 at the greater of (i) 6.125% or (ii) the rate of
interest applicable on April 1, 1992 to borrowings under the Credit Agreement
(as defined below under "Certain Transactions").
 
     In June 1990, Mr. Seidl also entered into an agreement with MAXXAM related
to his move to Houston, Texas, which was amended as of February 1991 and May
1991, and subsequently assigned to KACC. The agreement provided for
reimbursement to Mr. Seidl for certain expenses incurred in connection with such
move. This reimbursement amount for 1992 is reflected in the Summary
Compensation Table.
 
                                       62

<PAGE>   65
 
     Mr. Hutchcraft retired from the Company effective December 31, 1993. Mr.
Hutchcraft's prior employment agreement provided for a 1993 base salary of
$450,000 and for termination of his participation in the LTIP as of December 31,
1992, with payment of his estimated account balance thereunder as of December
31, 1992, with any adjustment from estimated to actual balance determined after
preparation of audited financial statements for 1992, to be made on or about
April 10, 1993. Pursuant to this agreement, Mr. Hutchcraft was paid $1,358,000
on December 31, 1992, and $18,874 on April 8, 1993, on account of his LTIP
account balance. In light of other compensation provisions in his agreement, Mr.
Hutchcraft received no bonus in 1992. Prior to the time of his election as
Chairman of the Board and Chief Executive Officer of the Company, Mr. Hutchcraft
served as Chief Operating Officer in addition to President of the Company and
his compensation was established pursuant to the base salary program and bonus
plan for executives and managers of the Company generally and based on those
same performance factors. The compensation set forth in Mr. Hutchcraft's
agreement was also established in recognition of his previous compensation
history, in anticipation of his additional responsibilities as Chairman of the
Board, and his potential leadership qualities and industry expertise widely
recognized in the Company and in the aluminum industry and also as an incentive
to Mr. Hutchcraft to continue in the employ of the Company.
 
     On April 1, 1993 the Company and KACC entered into an employment agreement
with Mr. George T. Haymaker, Jr. pursuant to which Mr. Haymaker joined the
Company and KACC in May 1993 as President and Chief Operating Officer. Mr.
Haymaker's agreement has a term of five (5) years. Pursuant to the agreement,
Mr. Haymaker was named Chairman of the Board and Chief Executive Officer of the
Company and KACC upon Mr. Hutchcraft's retirement on December 31, 1993. Mr.
Haymaker's employment agreement provides for a base salary of $450,000 per annum
commencing upon his joining the Company and KACC, and a bonus target of 50% of
his salary beginning fiscal year 1994. The agreement further provides that Mr.
Haymaker will not be paid a bonus for calendar year 1993. Any bonus actually
awarded for 1994 or thereafter could be less or greater than the target level,
depending upon corporate performance as compared to corporate plan objectives
usually established in January of each year, as well as individual performance.
Under the agreement, Mr. Haymaker received an initial award under the Plan of
options to purchase up to 100,000 shares of Common Stock at its fair market
value on the date of the award. Such options are to vest 20% per year for a
period of five (5) years. See "-- New Plan Benefits Table" above.
 
     In the event of a change of control of the Company or KACC which within one
year thereafter adversely affects Mr. Haymaker's title, position, duties,
responsibilities or compensation, Mr. Haymaker's employment agreement provides
that he may elect to be deemed terminated without cause, and therefore, entitled
to a severance payment equal to two times his base annual salary. Additionally,
in the event of such termination, Mr. Haymaker's options for 100,000 shares of
Common Stock shall fully vest.
 
     Mr. Pierno and MAXXAM entered into a five-year employment agreement
effective as of March 8, 1990. Pursuant to the terms of the agreement, Mr.
Pierno was entitled during the first six months of 1993 to a base salary of
$321,232 per year, which amount is increased each July by an amount not less
than the increase in the Consumer Price Index for that year. The agreement
provided for a bonus for the year 1992 in an amount not less than 75% and not
more than 125% of Mr. Pierno's then base salary. Although the agreement
specifies no bonus percentage for the years 1993 and 1994, in the agreement
MAXXAM expresses an intent to pay a bonus in the same percentage range. The
agreement also entitles Mr. Pierno to participate in employee benefit plans and
programs applicable to senior executives of MAXXAM.
 
     Mr. La Duc held the positions of Vice President and Chief Financial Officer
of KACC and the Company and Senior Vice President and Chief Financial Officer of
MAXXAM pursuant to an employment agreement among MAXXAM, the Company and Mr. La
Duc, which commenced September 26, 1990, and expired December 31, 1993. The
employment agreement provides for a base salary of $225,000 with any increases
at the discretion of the Company and MAXXAM. Currently, Mr. La Duc continues in
his employment in such positions with MAXXAM, KACC and the Company. Subject to
limitations pursuant to the LTIP, an annual bonus may be paid under the terms of
KACC's bonus plan. Mr. La Duc is eligible to participate in the employee benefit
plans and programs maintained by the Company and KACC, as from time to time in
effect, applicable to senior executives of KACC and the Company, including, but
not limited to, the LTIP and, if approved by the stockholders, the Plan.
 
                                       63

<PAGE>   66
 
     Mr. La Duc is entitled to reimbursement by the Company of certain moving
expenses incurred in connection with his relocation to Houston, Texas, and to
other benefits under the Company's executive relocation policy. The amount
reimbursed during 1992 pursuant to this arrangement is related in the Summary
Compensation Table.
 
     The Company and MAXXAM entered into an employment agreement with Mr. Joseph
A. Bonn, Vice President, Planning and Administration of the Company and a Vice
President of KACC. The employment agreement has a term of three years ending
June 30, 1994, and provides for a base salary of $210,000, which may increase at
the discretion of the Company and MAXXAM. Subject to limitations pursuant to the
LTIP, an annual bonus may be paid under the terms of the KACC bonus plan. Any
annual bonus amounts payable under the employment agreement will be reduced by
the amount of any directorship fees (during the year for which the annual bonus
is paid) received by Mr. Bonn in respect of board memberships held at the
request of the Company or MAXXAM. Mr. Bonn is eligible to participate in the
employee benefit plans and programs maintained by the Company, as from time to
time in effect, applicable to senior executives of the Company, including, but
not limited to, the LTIP and, if approved by stockholders, the Plan.
 
     Mr. Bonn subsequently relocated to Oakland, California. Pursuant to an
agreement dated December 20, 1991, KACC agreed to reimburse Mr. Bonn for
reasonable and necessary moving expenses from Texas to California (including the
expense of moving property, travel costs, and temporary living expenses) in
accordance with KACC's relocation policy; to reimburse Mr. Bonn for the
reasonable amount of net out-of-pocket loss, if any, incurred in the termination
of construction work in process in connection with Mr. Bonn's Texas residence
and incurred in the resale of the land upon which the residence was being
constructed (including reasonable transaction costs and expenses in connection
with the purchase and sale of the land and improvements, construction
termination fees, architectural, engineering and drafting fees and expenses, lot
clearing costs, and the like); and to reimburse Mr. Bonn for the reasonable
amount of the net out-of-pocket loss, if any, incurred on the sale, cancellation
or forfeiture of a country club membership acquired in Texas. This reimbursement
amount for 1992 is reflected in the Summary Compensation Table.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     No member of the Compensation Committee of the Board of Directors of the
Company was, during the 1992 fiscal year, an officer or employee of the Company
or any of its subsidiaries, or was formerly an officer of the Company or any of
its subsidiaries or, other than Mr. Levin, had any relationships requiring
disclosure by the Company under Item 404 of Regulation S-K. Mr. Levin served on
the Compensation Committee and Board of both the Company and KACC during 1992.
Mr. Levin is also a partner in the law firm of Kramer, Levin, Naftalis, Nessen,
Kamin & Frankel, which provided legal services for the Company and its
subsidiaries during 1992.
 
     During the Company's 1992 fiscal year, no executive officer of the Company
served as (i) a member of the Committee (or other board committee performing
equivalent functions) of another entity, one of whose executive officers served
on the Company's Compensation Committee, (ii) a director of another entity, one
of whose executive officers served on the Company's Compensation Committee, or
(iii) a member of the compensation committee (or other board committee
performing equivalent functions) of another entity, one of whose executive
officers served as a director of the Company.

                              CERTAIN TRANSACTIONS
 
   
     For periods through June 30, 1993, the Company and its subsidiaries
(including KACC) were members of an affiliated group of corporations (an
"Affiliated Group") within the meaning of Section 1504 of the Internal Revenue
Code of 1986, as amended (the "Code"), of which MAXXAM is the common parent
corporation (the "MAXXAM Tax Group"). Effective July 1, 1993, the Company and
its subsidiaries are no longer members of the MAXXAM Tax Group (the
"Deconsolidation") but are members of a new Affiliated Group of which the
Company is the common parent corporation (the "New Kaiser Tax Group"). The
taxable income and loss and tax credits for the Company and its subsidiaries for
the period January 1, 1993 through June 30, 1993, will be included in the 1993
MAXXAM Tax Group consolidated Federal income tax return (the "MAXXAM 1993 Tax
Return"). For periods beginning on and after July 1, 1993 (the "Post
Deconsolidation Periods"), the taxable income and loss and tax credits for the
Company and its subsidiaries will be included in the consolidated Federal income
tax returns to be filed for the New Kaiser Tax Group. The Company obtained the
approval of the Secretary of the Treasury in order to file a consolidated
Federal income tax return for the New Kaiser Tax Group for the period ended
December 31, 1993.
    
 
     As a consequence of the Deconsolidation, the KACC Tax Allocation Agreement
(as defined) and the Company Tax Allocation Agreement (as defined)
(collectively, the "Tax Allocation Agreements") terminated pursuant to their
terms, effective with respect to Post Deconsolidation Periods. The provisions of
the Tax Allocation Agreements will continue to govern periods ending before the
date of the Deconsolidation (the "Pre Deconsolidation Periods"). Therefore,
payments or refunds may still be required by or payable to the Company or KACC
under the Tax Allocation Agreements for Pre Deconsolidation Periods due to the
final resolution of audits, amended returns and related matters with respect to
such Pre Deconsolidation Periods. To the extent the New Kaiser Tax Group
generates unused tax losses or tax credits in Post Deconsolidation Periods, such
amounts will not be available to obtain refunds of amounts paid by the Company
or KACC to MAXXAM for Pre Deconsolidation Periods pursuant to the Tax Allocation
Agreements. It is anticipated that such losses and credits will be carried
forward to offset future Federal income taxes payable by the Company.
 
     Any unused tax attribute carryforwards existing as of the date of the
Deconsolidation under the terms of the Tax Allocation Agreements will be
eliminated and will not be available to offset Federal income tax liabilities of
the New Kaiser Tax Group for Post Deconsolidation Periods. Upon the filing of
the MAXXAM 1993 Tax Return, the tax attribute carryforwards of the MAXXAM Tax
Group as of December 31, 1993 will be apportioned in part to the New Kaiser Tax
Group, based upon the provisions of the relevant consolidated return
regulations. It is anticipated that the amounts of such tax attribute
carryforwards apportioned to the New Kaiser Tax Group will approximate or exceed
the amounts of tax attribute carryforwards eliminated under the Tax Allocation
Agreements. Although the amounts of tax attribute carryforwards apportioned to
the New Kaiser Tax Group will be determined as of December 31, 1993, they will
be available as of the date of the Deconsolidation, subject to certain
limitations, to reduce Federal income taxes payable by the New Kaiser Tax Group
for Post Deconsolidation Periods.
 
     In 1989, KACC and MAXXAM entered into a tax allocation agreement (the "KACC
Tax Allocation Agreement"). Pursuant to the terms of the KACC Tax Allocation
Agreement, MAXXAM pays any consolidated Federal income tax liability for the
MAXXAM Tax Group. KACC is liable to MAXXAM for the Federal income tax liability
of KACC and its subsidiaries (collectively, the "KACC Subgroup") computed as if
the KACC Subgroup were a separate Affiliated Group which was never affiliated
with the MAXXAM Tax Group (taking into account all limitations under the Code
and regulations applicable to the KACC Subgroup), except that the KACC Subgroup
excludes interest income received or accrued on an intercompany note issued by
the Company in connection with a financing consummated in December 1989 (the
"KACC Subgroup's Separate Income Tax Liability"). To the extent such calculation
resulted in a net operating loss or a net capital loss or credit which the KACC
Subgroup could have carried back to a prior taxable period under the principles
of Sections 172 and 1502 of the Code, MAXXAM pays to KACC an amount equal to the
tax refund to which KACC would have been entitled (but not in excess of the
aggregate net amount previously paid by KACC to MAXXAM for the current year and
the three prior years). If such separately calculated net operating loss or net
capital loss or credit of the KACC Subgroup can not be carried back to a prior
taxable year of the KACC Subgroup for which the KACC Subgroup paid its separate
tax
 
                                       65

<PAGE>   68
 
liability to MAXXAM, the net operating loss or net capital loss or credit
becomes a loss or credit carryover of the KACC Subgroup to be used in computing
the KACC Subgroup's Separate Income Tax Liability for future taxable years. The
same principles were applied to any consolidated or combined state or local
income tax returns filed by the MAXXAM Tax Group with respect to KACC and its
subsidiaries. Although, under Treasury regulations, all members of the MAXXAM
Tax Group, including the members of the KACC Subgroup, are severally liable for
the MAXXAM Tax Group's Federal income tax liability for all of 1993 and
applicable prior periods, under the KACC Tax Allocation Agreement, MAXXAM
indemnifies each KACC Subgroup member for all Federal income tax liabilities
relating to taxable years during which such KACC Subgroup member was a member of
the MAXXAM Tax Group, except for payments required under the KACC Tax Allocation
Agreement.
 
     During 1992, under the KACC Tax Allocation Agreement, KACC made a payment
to MAXXAM of $28.0 million in respect of the year ended December 31, 1991. The
eighth amendment to the Credit Agreement, dated as of January 7, 1993 (the
"Eighth Amendment"), prohibits the payment by KACC to MAXXAM of any additional
amounts due under the KACC Tax Allocation Agreement until December 15, 1994.
KACC estimates that it owes MAXXAM approximately $8.7 million in respect of the
year ended December 31, 1992. Inasmuch as KACC will record tax losses in the
period January 1, 1993 through June 30, 1993, and that such losses will be
carried back to prior taxable periods under the terms of the KACC Tax Allocation
Agreement, it is estimated that MAXXAM owes KACC approximately $20.0 million
with respect to such losses.
 
     In 1991, MAXXAM and the Company entered into a tax allocation agreement
(the "Company Tax Allocation Agreement"). Pursuant to the terms of the Company
Tax Allocation Agreement, the Federal income tax liability of the Company and
its subsidiaries (collectively, the "Company Subgroup") is computed using the
same principles used in the KACC Tax Allocation Agreement to determine the KACC
Subgroup's income tax liability. To the extent such tax liability (the
"Company's Separate Income Tax Liability") for any applicable period exceeds the
KACC Subgroup's Separate Income Tax Liability for such period, the Company is
obligated to pay the amount of such difference to MAXXAM. To the extent that the
Company's Separate Income Tax Liability for any applicable period is less than
the KACC Subgroup's Separate Income Tax Liability for such period, MAXXAM is
obligated to pay the amount of such difference to the Company (but not in excess
of the aggregate net amount previously paid by the Company and KACC to MAXXAM
for the current year and the three prior years). The foregoing principles are
also applied to any consolidated or combined state or local income tax returns
filed by the MAXXAM Tax Group with respect to the Company. While the Company is
severally liable for the MAXXAM Tax Group's Federal income tax liability for all
of 1993 and applicable prior periods, pursuant to the Company Tax Allocation
Agreement, MAXXAM indemnifies the Company according to the same principles as
those applied to KACC Subgroup members under the KACC Tax Allocation Agreement.
 
     During 1992, under the Company Tax Allocation Agreement, MAXXAM made a
payment to the Company of $45,000 in respect of the year ended December 31,
1991. The Company estimates the amounts due from MAXXAM in respect of the year
ended December 31, 1992 and for the period January 1, 1993, through the date of
the Deconsolidation to be approximately $84,000 and $42,000, respectively.
 
     Under the current consolidated return regulations, the Deconsolidation
caused certain tax basis adjustments and the recognition of certain types of
taxable income (including amounts that were previously deferred), none of which
the Company believes to be material.
 
     On June 30, 1993, the Company and KACC entered into a tax allocation
agreement (the "New Tax Allocation Agreement") effective for Post
Deconsolidation Periods. The terms of the New Tax Allocation Agreement are
similar, in all material respects, to those of the KACC Tax Allocation Agreement
except that KACC is liable to the Company.
 
     The Company and MAXXAM have an arrangement pursuant to which they reimburse
each other for certain allocable costs associated with the performance of
services by their respective employees, and KACC also pays to MAXXAM amounts in
respect of directors' fees for directors of KACC who are not employees of KACC
and who are directors of MAXXAM. During 1992 and during the first nine months of
1993, KACC
 
                                       66

<PAGE>   69
 
paid a total of approximately $2.0 million and $1.8 million, respectively, to
MAXXAM pursuant to such arrangements, and MAXXAM paid approximately $1.4 million
and $0.6 million, respectively, to KACC pursuant to such arrangements.
 
     As a condition to the effectiveness of the Eighth Amendment, KACC issued
the MAXXAM Note in the principal amount of $15.0 million, which evidenced a cash
loan in the amount of $15.0 million made to KACC. On June 30, 1993, the MAXXAM
Note was exchanged for 2,132,950 $.65 Depositary Shares. The Company made a
capital contribution of the MAXXAM Note to KACC, which resulted in the
extinguishment of the MAXXAM Note.
 
     The Company paid cash dividends on its Common Stock in the amount of $2.9
million in each quarter of 1992. In the event the Company pays any distributions
to its holders of Common Stock (including the payment of regular quarterly cash
dividends), the Eighth Amendment requires MAXXAM and any subsidiary of MAXXAM to
use the entire proceeds of any such distributions received by MAXXAM or any
subsidiary of MAXXAM to purchase a PIK Note from KACC. On December 15, 1992,
KACC issued a PIK Note to a subsidiary of MAXXAM in the principal amount of $2.5
million, representing the entire amount of the dividend received by such
subsidiary in respect of the shares of the Company's Common Stock which it owns.
The PIK Note bears interest, compounded semiannually, at a rate equal to 12% per
annum, and is due and payable, together with accrued interest thereon, on June
30, 1995. KACC is not required to make any payment of principal of or interest
on the PIK Note prior to June 30, 1995. However, to the extent not prohibited by
the Credit Agreement, KACC may be required to prepay the PIK Note upon demand.
The Credit Agreement currently prohibits the payment of principal and interest
on the PIK Note. Additional PIK Notes issued by KACC, if any, will have terms
substantially similar to the terms of the PIK Note described herein.
 
     In February 1993, MAXXAM entered into a commercial guaranty of payment (the
"Guaranty") of a promissory note dated January 28, 1993, in the original
principal amount of $150,000 issued by Mr. Anthony R. Pierno, Vice President and
General Counsel of the Company, to Charter National Bank -- Houston. The
Guaranty is subject to an agreement between MAXXAM and Mr. Pierno that any
payment by MAXXAM under the Guaranty shall be offset in like amount plus
interest at 12% per annum from the date of payment on the Guaranty to the date
of payment to MAXXAM by Mr. Pierno. Such offset may be made from any payments
due Mr. Pierno from MAXXAM which lawfully may be the subject of such offset,
including any payment under any compensation arrangement or employee benefit
plan. The Guaranty was entered into by MAXXAM for the convenience of Mr. Pierno.
 
     Pursuant to the terms of Mr. Pierno's employment agreement, personal loans
of Mr. Pierno outstanding on the date of the agreement are forgiven at the rate
of $15,000 per year beginning March 8, 1991, with any remaining balance being
due and payable upon Mr. Pierno's termination of employment. At the time of the
agreement, MAXXAM had loaned an aggregate of $150,000 at 6% interest to Mr.
Pierno. The principal balance on such loans as of November 30, 1993 was
$105,000. Such loans are payable on demand, require monthly interest payments
and are secured by real estate owned by Mr. Pierno. The agreement also provided
for up to an additional $200,000 in loans to Mr. Pierno bearing interest at 6%
per annum, with interest being payable monthly and principal being due December
15, 1994 (with prepayments due upon the exercise by Mr. Pierno of any stock
appreciation rights granted pursuant to the employment agreement). All of such
amount has been borrowed by Mr. Pierno.
 
     Mr. Levin, a director of the Company, is a partner of the law firm of
Kramer, Levin, Naftalis, Nessen, Kamin & Frankel, which provides legal services
for the Company and its subsidiaries. See "Legal Matters."

                     DESCRIPTION OF PRINCIPAL INDEBTEDNESS
 
   
     The New Credit Agreement. On January 24, 1994, KACC entered into the
Commitment Letter with Bank of America and BA which contains the principal terms
and conditions with respect to the New Credit Agreement. The expected terms and
conditions of the New Credit Agreement are summarized below. Bank of America and
BA have committed, subject to the terms and conditions of the Commitment Letter,
to provide the full $250.0 million of the New Credit Agreement.
    
 
          - Facility. The New Credit Agreement will consist of a $250.0 million
five-year secured, revolving line of credit. KACC will be able to borrow under
the facility by means of revolving credit advances, swingline advances (up to
$25.0 million) and letters of credit in an aggregate amount equal to the lesser
of $250.0 million or a borrowing base consisting of 85% of eligible accounts
receivable (as defined) plus 65% of eligible inventory (as defined) (with
availability against such eligible inventory not to exceed $175.0 million at any
one time).
 
   
          - Interest Rates. Loans under the New Credit Agreement will bear
interest at a rate per annum, at KACC's election, equal to (i) a Reference Rate
(as defined) plus 1.50% or (ii) LIBOR (as defined) plus 3.25%. After June 30,
1995, the interest rate margins applicable to borrowings under the New Credit
Agreement may be reduced (non-cumulatively), based upon KACC's Interest Coverage
Ratio (as defined) ("ICR"), as follows: ICR 1.25, reduction of 0%; 1.25 ICR
1.50, reduction of 0.50%; 1.50 ICR 2.00, reduction of 1.00%; and ICR 2.00,
reduction of 1.50%. ICR will be defined as the ratio of (i) EBITDA (as defined),
less Adjusted Capital Expenditures (as defined), to (ii) adjusted interest
expense.
    
 
          - Guaranties. The New Credit Agreement will be unconditionally
guaranteed by the Company and by all significant subsidiaries of KACC which are
subsidiary guarantors under the Credit Agreement.
 
   
          - Security. The New Credit Agreement will be secured by substantially
the same assets securing the Credit Agreement, and will include a pledge of the
stock of KACC and its material subsidiaries and the grant of a lien on all now
existing and hereafter acquired receivables, inventory, intangibles and certain
other assets of the Company, KACC and its subsidiaries. However, the New Credit
Agreement will not be secured by the Company's Gramercy alumina refinery.
    
 
          - Payments and Fees. The New Credit Agreement will permit repayments
of base rate advances in minimum amounts of $1.0 million and prepayments of
LIBOR advances in minimum amounts of $5.0 million. Lenders will be entitled to
receive a risk participation fee equal to 3% per annum on their respective share
of the total amount of letters of credit outstanding, subject to reduction under
certain circumstances. A commitment fee equal to 0.50% per annum will be
payable, quarterly in arrears, on the unutilized portion of the New Credit
Agreement.
 
   
          - Covenants. The New Credit Agreement will contain certain affirmative
and negative covenants including, but not limited to, covenants relating to (i)
the incurrence of liens and additional indebtedness, (ii) the making of
restricted payments and the payment of fees to MAXXAM, (iii) Asset Dispositions
(as defined), (iv) the sale of accounts receivable, (v) the maximum permitted
amount of capital expenditures each year, (vi) mergers, acquisitions and
investments, (vii) leases and sale-leasebacks, (viii) transactions with
affiliates, and (ix) the maintenance of a minimum net worth and ICR. The
covenant relating to the maintenance of the ICR will not become applicable under
the New Credit Agreement until March 31, 1996. In addition, the New Credit
Agreement will not permit the Company or KACC to pay any dividends on their
common stock.
    
 
   
     The New Credit Agreement will (i) prohibit redemptions or repurchases of
the Senior Notes, including, without limitation, purchases of Senior Notes that
might otherwise be required pursuant to the provisions of the Senior Note
Indenture, (ii) prohibit, without the written consent of the Required Lenders
(as defined in the New Credit Agreement), amendments or supplements to the
Senior Note Indenture and (iii) prohibit, with certain exceptions, the taking of
action, or permitting to exist any condition, which would require (a) any
subsidiary of the Company (other than the initial Subsidiary Guarantors under
the Senior Note Indenture) to guarantee the Senior Notes or (b) the Company or
any of its Subsidiaries to provide collateral in respect of the Senior Notes.
    
 
                                       68

<PAGE>   71
 
   
          - Events of Default. The New Credit Agreement will contain certain
events of default substantially similar to the events of default contained in
the Credit Agreement, including, but not limited to, payment defaults, cross
defaults to other indebtedness, covenant defaults, breach of representation,
bankruptcy and similar events, ERISA violations, any requirements to repurchase
the Senior Notes and breaches of collateral documents.
    
 
   
          - Conditions to Initial Funding. The obligations of Bank of America
and BA under the Commitment Letter are subject to certain conditions, including,
but not limited to the requirement that the Company and KACC shall have raised
not less than $250.0 million aggregate gross proceeds of new capital pursuant to
the offering of shares of PRIDES and the Senior Notes.
    
 
   
     Issuance of Senior Notes. In connection with the offering of the PRIDES
hereby, KACC is concurrently offering $175.0 million aggregate principal amount
of Senior Notes pursuant to a separate registration statement filed with the
Commission. The following is a summary of certain material terms of the Senior
Notes expected to be contained in the Indenture governing the Senior Notes (the
"Senior Note Indenture").
    
 
   
          - Ranking. The Senior Notes will represent senior, unsecured
obligations of KACC, ranking senior in right and priority of payment to all
indebtedness of KACC that by its terms is expressly subordinated to the Senior
Notes. The Senior Notes will rank pari passu in right and priority of payment
with all senior indebtedness, including indebtedness under the New Credit
Agreement.
    
 
   
          - Guarantee. The obligations of KACC with respect to the Senior Notes
will be unconditionally guaranteed, jointly and severally, on a senior,
unsecured basis by certain subsidiaries of KACC.
    
 
   
          - Optional Redemption. The Senior Notes will be redeemable at the
option of KACC, in whole or in part, at any time after February 15, 1998, at the
redemption prices set forth in the Senior Notes, plus accrued and unpaid
interest to the redemption date.
    
 
   
          -Offer to Purchase the Senior Notes. Upon a Change of Control (as
defined in the Senior Note Indenture), KACC will be required to make an offer to
purchase the Senior Notes at 101% of the principal amount thereof, plus accrued
and unpaid interest to the date of purchase. In addition, KACC will be required
to make an offer to purchase the Senior Notes under certain circumstances if the
Company has available Net Cash Proceeds (as defined in the Senior Note
Indenture) as a result of Asset Sales (as defined in the Senior Note Indenture).
Any Change of Control, and any repurchase of the Notes upon a Change of Control
or Asset Sale, would constitute an event of default under the New Credit
Agreement.
    
 
   
          - Covenants. The Senior Note Indenture will contain certain
affirmative and negative covenants, including, but not limited to, covenants
imposing limitations on: (i) Asset Sales, (ii) transactions with affiliates,
(iii) restricted payments and restricted investments, (iv) the incurrence of
indebtedness and preferred stock, (v) the granting of liens to secure
indebtedness on U.S. Fixed Assets (as defined), (vi) the transfer of assets to
entities that are not guarantors of the Senior Notes, (vii) mergers and
consolidations and (viii) dividend and other payment restrictions affecting
subsidiaries of KACC.
    
 
   
          - Events of Default. The Senior Note Indenture will contain certain
events at default, including, but not limited to, (i) payment defaults, (ii)
covenant defaults, (iii) cross payment defaults and cross accelerations to other
indebtedness, (iv) certain final judgments against KACC and its significant
subsidiaries, (v) bankruptcy and similar events and (vi) any guarantee of the
Senior Notes being held invalid or unenforceable or ceasing to be in full force
and effect, except in accordance with the Senior Note Indenture.
    
 
   
     Existing Indebtedness. In December 1989, the Company and KACC entered into
the Credit Agreement, and KACC issued $350.0 million of the 14 1/4% Notes
(collectively, the "Financing"). The net proceeds of the Financing, together
with the $180.0 million initial payment received by the Company in respect of a
forward alumina sales transaction ("FAST") and other available funds, were used
to retire $925.0 million principal amount of Increasing Rate Notes of the
Company, to prepay certain indebtedness of KACC, to pay related fees and
expenses, and to pay a $50.0 million dividend to a subsidiary of MAXXAM.
    
 
     The Credit Agreement consisted of a $350.0 million five-year revolving
credit facility, a $125 million five-year term loan, a $75.0 million two-year
bridge loan, and a $172.0 million three and one-half year standby
 
                                       69

<PAGE>   72
 
letter of credit which secured the advance payment on the FAST. As of September
30, 1993, the bridge loan and the term loan under the Credit Agreement were
fully repaid, the letter of credit issued in connection with the FAST had been
fully amortized, $165.0 million of borrowings and $36.1 million of letters of
credit were outstanding under the revolving credit facility and $148.9 million
of borrowing capacity was unused under the revolving credit facility.
 
     The Credit Agreement contains a number of affirmative and negative
covenants, which among other things (a) prohibit KACC from engaging in business
significantly different from that currently conducted by it, (b) limit the
incurrence of additional indebtedness and liens, (c) limit Investments (as
defined), (d) limit capital expenditures, (e) limit mergers and consolidations,
(f) restrict Asset Dispositions (as defined), (g) limit transactions with
Affiliates (as defined), (h) restrict KACC's ability to pay dividends and make
other distributions to its stockholders and (i) require the maintenance of a (1)
minimum Current Ratio (as defined) (2) minimum Net Worth (as defined), (3)
maximum Leverage Ratio (as defined) and (4) minimum Interest Coverage Ratio (as
defined).
 
     KACC's obligations under the Credit Agreement are guaranteed by the Company
and certain of KACC's subsidiaries. In addition, the Credit Agreement is secured
by, among other things, (i) mortgages on KACC's facilities in Trentwood, Mead
and Tacoma, Washington; Gramercy, Louisiana (which will not constitute part of
the security under the New Credit Agreement); Erie, Pennsylvania; Newark, Ohio;
and Sherman, Texas, (ii) subject to certain exceptions, liens on accounts
receivable, inventory, equipment, domestic patents and trademarks and
substantially all other personal property of KACC and certain of its
subsidiaries, (iii) a pledge of all of the stock of KACC owned by the Company
and (iv) pledges of all of the stock of certain of KACC's wholly owned domestic
subsidiaries, pledges of a portion of the stock of certain foreign subsidiaries
and pledges of a portion of the stock of certain partially owned foreign
affiliates.
 
     Loans under the Credit Agreement bear interest at a base rate per annum, at
KACC's election from time to time, equal to (i) the Reference Rate (as defined)
plus 1 1/2%, (ii) the CD Rate (Reserve Adjusted) (as defined) plus 2 5/8%, or
(iii) the LIBO Rate (Reserve Adjusted) (as defined) plus 2 1/2%. KACC is
currently required to pay fees equal to 2 1/2% per annum on the average
aggregate amount outstanding of letters of credit under the Credit Agreement.
The Credit Agreement contains provisions for the reduction or increase of the
base interest rates and letter of credit fees, based upon the Interest Coverage
Ratio, determined quarterly, under which the base interest rates could be
reduced or increased by 1/2 of 1% per annum, on a non-cumulative basis (based
upon the Interest Coverage Ratio, the Company's base interest rates and letter
of credit fees have been increased by 1/2 of 1% per annum). In addition to the
above fees, there is a commitment fee equal to  1/2% per annum on any unused
portion of the revolving credit facility.
 
     On February 1, 1993, KACC extended a portion of its debt maturities by
refinancing the 14 1/4% Notes with $400.0 million aggregate principal amount of
the 12 3/4% Notes. Subject to certain exceptions, the 12 3/4% Note Indenture
requires KACC to satisfy certain financial tests and other conditions (including
the satisfaction of a consolidated fixed charge coverage ratio) in order to pay
dividends and limits the amount of cash dividends payable by KACC to (i) the sum
of (A) 50% of the Consolidated Net Income (as defined; such definition, among
other things, excludes the one time charge of $497.7 million incurred as a
result of the cumulative effect of the adoption of SFAS 106) of KACC accrued
(or, if the aggregate Consolidated Net Income of KACC for such period shall be a
deficit, minus 100% of such deficit) for the period (taken as one accounting
period) from January 1, 1993 to the end of KACC's most recently ended fiscal
quarter for which financial statements are available at the time such dividends
are declared or paid, plus (B) the aggregate net proceeds received by KACC after
December 31, 1992, as capital contributions or from the issuance or sale (other
than to a Non-Affiliate Joint Venture (as defined) or to a Subsidiary (as
defined) of KACC) of Capital Stock (as defined) other than Redeemable Stock (as
defined) or from the issuance or sale of any debt or other security of KACC
convertible or exercisable into such Capital Stock that has been so converted or
exercised minus (ii) the aggregate amount of Restricted Investments (as defined)
then outstanding, subject to certain adjustments.
 
     The declaration and payment of dividends by the Company and KACC on their
shares of common stock are currently subject to certain covenants contained in
the Credit Agreement and, in the case of KACC, the
 
                                       70

<PAGE>   73
 
12 3/4% Note Indenture. Under the most restrictive of these covenants, neither
the Company nor KACC is currently permitted to pay dividends on its common

     The 12 3/4% Note Indenture contains a number of affirmative and negative
covenants applicable to KACC which, among other things, (a) limit the incurrence
of additional indebtedness and liens, (b) limit Restricted Payments (as
defined), (c) limit Restricted Investments (as defined), (d) limit mergers,
consolidations and sales of all or substantially all of KACC's assets, (e)
impose certain requirements with respect to Asset Sales (as defined), (f) limit
transactions with Affiliates (as defined), (g) prohibit, with certain
exceptions, restrictions on the ability of any Subsidiary to pay dividends, make
certain other distributions, pay indebtedness owed to KACC or another
Subsidiary, make loans or advances to KACC or another Subsidiary or transfer any
of its assets to KACC, (h) require KACC to repurchase 12 3/4% Notes at a premium
upon the occurrence of a Change of Control (as defined) if so requested by the
holder thereof, and (i) prohibit, with certain exceptions, the incurrence of
indebtedness that is both subordinated to Senior Indebtedness (as defined) and
senior to the 12 3/4% Notes.
 
     In December 1991, Alpart entered into a $60 million loan agreement with
CARIFA under which CARIFA loaned Alpart the proceeds from the issuance of
CARIFA's Industrial Revenue bonds. Proceeds from the sale of the bonds were used
by Alpart to refinance the interim loans from the partners in Alpart, to pay
eligible project costs for expansion and modernization of its refinery and to
pay certain costs of issuance. Alpart's obligations under the loan agreement are
secured by a $64.2 million letter of credit severally guaranteed by the partners
in Alpart (of which $22.5 million is guaranteed by the minority partner in
Alpart). See Note 7 of the Notes to the Consolidated Financial Statements and
Note 3 of the Notes to the Interim Financial Statements.
 
     In December 1992, KACC entered into the Sale Agreement with the Louisiana
Parish. To fund the acquisition of the facilities, the Louisiana Parish issued
$20.0 million aggregate principal amount of the Gramercy Bonds, the proceeds of
which were deposited into a construction fund established under the related
indenture and which may be withdrawn from the construction fund, from time to
time, pursuant to the terms of such indenture and the related Sale Agreement.
The Sale Agreement requires KACC to pay the purchase price of the facilities in
installments due on the dates and in the amounts required to permit the
Louisiana Parish to satisfy all of its payment obligations under the related
indenture.
 
     In connection with the offering of the $.65 Depositary Shares in June 1993,
the Company made a non-interest bearing loan to KACC in the principal amount of
$37,796,753 (an amount equal to the aggregate dividends scheduled to accrue on
the Series A Shares issued in June 1993 from the issuance date until the date on
which the Series A Shares mandatorily convert into shares of the Company's
Common Stock). The loan is evidenced by an intercompany note which matures on
June 29, 1996, and is payable in quarterly installments. As of December 31,
1993, the aggregate principal amount of such intercompany note was $31,497,294.
 
     The Company expects to make dividend payments on the shares of PRIDES out
of funds provided to it by KACC pursuant to the terms of the Intercompany Note.
The Intercompany Note is designed to provide sufficient funds to the Company to
enable it to make dividend payments on the shares of PRIDES until the Mandatory
Conversion Date. The Intercompany Note will mature on December 31, 1997, and
will be payable in quarterly installments.

                           DESCRIPTION OF THE PRIDES
 
     The following is a summary of the material provisions of the shares of
PRIDES. The summary is qualified by reference to the full text of the Company's
Certificate of Incorporation (as defined below) and the form of Certificate of
Designations, both of which are filed as exhibits to the Registration Statement,
which exhibits may be obtained from the Company by writing to the Secretary of
the Company, 5847 San Felipe, Suite 2600, Houston, Texas 77057.
 
   
     The Board of Directors has adopted resolutions authorizing the issuance of
up to 9,200,000 shares of PRIDES out of the Company's authorized and unissued
Preferred Stock. The PRIDES will rank on a parity with the Series A Shares and
any other classes or series of stock ranking on a parity with the PRIDES that
may from time to time be issued by the Company in respect of the payment of
dividends and the distribution of assets upon liquidation.
    
 
   
     Dividends.  Subject to the rights of holders of Series A Shares and holders
of other classes or series of stock ranking on a parity with or senior to the
PRIDES that may from time to time be issued by the Company, the holders of
PRIDES are entitled to receive, when, as and if the Board of Directors declares
dividends on the PRIDES, out of funds legally available for dividends,
cumulative preferential cash dividends from the issue date of the PRIDES,
accruing at the rate per share of PRIDES of $            per annum or
$            per quarter, payable quarterly in arrears on the last day of each
March, June, September and December, or, if any such date is not a business day,
on the next succeeding day that is a business day; provided, however, that, with
respect to any dividend period during which a redemption occurs, the Company
may, at its option, declare accrued dividends on the shares of PRIDES to, and
pay such accrued dividends on, the redemption date, in which case such dividends
shall be payable to the holders of shares of PRIDES as of the record date for
such dividend payment and shall not be included in the calculation of the Call
Price (as defined below). The first dividend payment will be for the period from
the issue date of the PRIDES to and including March 30, 1994 and will be paid on
March 31, 1994. Dividends on the PRIDES will be payable to holders of record as
they appear on the books of the Company or any transfer agent for the PRIDES on
such record dates, not less than 10 nor more than 50 days preceding the payment
dates thereof, as shall be fixed by the Board of Directors. Dividends in arrears
for any past quarterly dividend periods may be declared and paid at any time
without reference to any regular dividend payment date to holders of record on
such date, not exceeding 50 days preceding the payment date thereof, as shall be
fixed by the Board of Directors. Dividends will cease to accrue in respect of
the shares of PRIDES on the earlier of (i) the day immediately prior to the
Mandatory Conversion Date or, subject to the provisions described in the last
sentence of the first paragraph under "Optional Redemption," (ii) the day
immediately prior to their earlier redemption. Dividends (or amounts equal to
accrued and unpaid dividends) payable on the shares of PRIDES for any period
shorter than a quarterly dividend period will be computed on the basis of a 360
day year of twelve 30-day months.
    
 
     Dividends on the PRIDES will accrue whether or not the Company has
earnings, whether or not there are funds legally available for the payment of
such dividends and whether or not such dividends are declared and will
accumulate to the extent they are not paid on the dividend payment date for the
quarter for which they accrue. Except as described below, accumulated unpaid
dividends will not bear interest.
 
     So long as any shares of PRIDES or a Deposit Deficit (as defined below) are
outstanding, except as set forth in the next succeeding sentence (unless a
Deposit Deficit is outstanding), no dividends shall be declared or paid or set
apart for payment on, and no other distribution shall be ordered or made on
(other than dividends or distributions paid in shares of, or options, warrants
or rights to subscribe for or purchase shares of, stock ranking junior to the
PRIDES in respect of dividends and the distribution of assets upon Liquidation),
nor (except for redemptions or conversions of Series A Shares or shares of
PRIDES pursuant to the applicable certificate of designations for such shares)
shall any sum or sums be set aside for, in a sinking fund or otherwise, or
applied to the purchase, redemption or other acquisition for value of, shares of
PRIDES, Series A Shares or any other class or series of stock ranking on a
parity with or junior to the PRIDES in respect of dividends or the distribution
of assets upon Liquidation (or, if any Deposit Deficit is outstanding, any class
or series of stock of the Company), unless all cumulative dividends accumulated
on the PRIDES shall have been or shall contemporaneously be declared and paid in
full or shall be declared and a sum sufficient for the
 
                                       72

<PAGE>   75
 
payment in full thereof set apart for such payment on the PRIDES (or, if any
Deposit Deficit is outstanding, unless such Deposit Deficit and all accrued
interest thereon shall have been paid in full). When dividends are not paid in
full, as aforesaid, all dividends declared upon the shares of PRIDES and any
other class or series of outstanding stock ranking on a parity with the PRIDES
in respect of dividends shall be declared pro rata so that the amount of
dividends declared per share on the PRIDES and such other stock shall in all
cases bear to each other the same ratio that accrued and unpaid dividends per
share on the PRIDES and such other stock bear to each other. Holders of PRIDES
shall not be entitled to any dividends, whether payable in cash, property or
stock, in excess of full cumulative dividends as described herein.
 
     Mandatory Conversion of PRIDES.  Unless previously either redeemed or
converted at the option of the holder into Common Stock, as described below, on
the Mandatory Conversion Date each outstanding share of PRIDES will convert
automatically into shares of Common Stock at the Common Equivalent Rate (as
described below) in effect on the Mandatory Conversion Date and the right to
receive an amount in cash equal to all accrued and unpaid dividends on such
shares of PRIDES (other than previously declared dividends payable to a holder
of record as of a prior date) to and including the day immediately prior to the
Mandatory Conversion Date. If an amount equal to the accrued and unpaid
dividends referred to in the preceding sentence (the "Required Dividend Amount")
is not deposited with a bank or trust company on or prior to the Mandatory
Conversion Date (the amount, if any, by which the Required Dividend Amount
exceeds the amount so deposited in respect of the Required Dividend Amount being
referred to as the "Deposit Deficit"), the Company shall, out of funds legally
available therefor, as promptly as practicable following the Mandatory
Conversion Date, deposit cash with a bank or trust company in an amount equal to
the Deposit Deficit plus an amount equal to interest at the rate of 11.0% per
annum on the Deposit Deficit from time to time outstanding from and including
the Mandatory Conversion Date to but not including the date the Deposit Deficit
is reduced to zero; provided, that so long as a Deposit Deficit is outstanding,
no class or series of stock thereafter issued by the Company shall rank senior
to the claims of the holders of the shares of PRIDES on the Mandatory Conversion
Date with regard to the Required Dividend Amount and interest thereon as and to
the extent provided in the Certificate of Designations.
 
     The Common Equivalent Rate is initially one share of Common Stock for each
share of PRIDES. The Common Equivalent Rate is subject to adjustment as
described below.
 
   
     Optional Redemption.  Shares of PRIDES are not redeemable by the Company
before December 31, 1996 (the "Initial Redemption Date"). At any time or from
time to time on or after the Initial Redemption Date until immediately before
the Mandatory Conversion Date, the Company has the right to call, in whole or in
part, the outstanding shares of PRIDES for redemption. On the redemption date,
the Company shall deliver to the holders thereof in exchange for each such share
of PRIDES called for redemption a number of shares of Common Stock equal to the
greater of (i) the Call Price (as defined below) in effect on the redemption
date divided by the Current Market Price per share of Common Stock determined as
of the second trading day immediately preceding the Notice Date (as defined
below) or (ii)           of a share of Common Stock (subject to adjustment in
the same manner as the Optional Conversion Rate is adjusted, as described
below). If all shares of Common Stock described in the immediately preceding
sentence are not deposited with a bank or trust company on or prior to the
redemption date, such redemption shall not be effective.
    
 
     The Call Price of each share of PRIDES is the sum of (i) $          on and
after the Initial Redemption Date, to and including March 30, 1997; $
on and after March 31, 1997, to and including June 29, 1997; $          on and
after June 30, 1997, to and including September 29, 1997; $          on and
after September 30, 1997, to and including November 29, 1997; and $          on
and after November 30, 1997, to and including December 30, 1997; and (ii) all
accrued and unpaid dividends thereon to but not including the date fixed for
redemption (other than previously declared dividends payable to a holder of
record as of a prior date).
 
     The "Current Market Price" per share of Common Stock on any date of
determination means the lesser of (i) the average of the daily Closing Prices
(as defined below) for the fifteen consecutive trading days ending on and
including such date of determination, or (ii) the Closing Price for such date of
determination; provided, however, that, for purposes of calculating the Current
Market Price in connection with any
 
                                       73

<PAGE>   76
 
redemption of PRIDES, if any adjustment of the Common Equivalent Rate becomes
effective as of any date during the period beginning on the first day of such
fifteen-day period and ending on the date on which shares of PRIDES are to be
redeemed, then the Current Market Price as determined pursuant to the foregoing
will be adjusted to the extent appropriate to reflect such adjustment.
 
     The "Notice Date" with respect to any notice given by the Company in
connection with a redemption of shares of PRIDES means the date on which first
occurs either the public announcement of such redemption or the commencement of
the mailing of such notice to the holders of shares of PRIDES.
 
     The term "Closing Price" on any day means the closing sales price regular
way on such day or, in case no such sale takes place on such day, the average of
the reported closing bid and asked quotations regular way, in each case on the
New York Stock Exchange, or, if the Common Stock is not listed or admitted to
trading on such Exchange, on the principal national securities exchange on which
the Common Stock is listed or admitted to trading, or, if not listed or admitted
to trading on any national securities exchange, the average of the high bid and
low asked quotations of the Common Stock in the over-the-counter market on the
day in question as reported by the National Quotation Bureau Incorporated, or a
similarly generally accepted reporting service, or, if no such quotations are
available, the fair market value of the Common Stock as determined by any New
York Stock Exchange member firm selected from time to time by the Board of
Directors of the Company for that purpose.
 
     If fewer than all the outstanding shares of PRIDES are to be called, the
shares of PRIDES to be called shall be selected by the Company from outstanding
shares of PRIDES by lot or on a pro rata basis or by any other method determined
by the Board of Directors of the Company in its sole discretion to be equitable.
 
     The Company will provide notice of any redemption of shares of PRIDES to
holders of record of shares of PRIDES to be called not less than 15 nor more
than 60 days prior to the date fixed for redemption. Accordingly, the earliest
Notice Date for any call for redemption of shares of PRIDES will be November 1,
1996. Any such notice shall be provided by mailing notice of redemption to the
holders of record of shares of PRIDES to be redeemed at each such holder's
address as it appears on the stock register of the Company; provided, however,
that no failure to give such notice nor any defect therein shall affect the
validity of the proceeding for redemption except as to the holders of shares of
PRIDES to which the Company has failed to give said notice of redemption or as
to the holders of shares of PRIDES whose notice of redemption was defective.
 
     Conversion at the Option of the Holder.  The shares of PRIDES are
convertible at the option of the holders thereof, at any time before the
Mandatory Conversion Date, unless previously redeemed, into shares of Common
Stock, at a rate of of a share of Common Stock for each share of PRIDES (the
"Optional Conversion Rate"), equivalent to a conversion price of $ per share of
Common Stock (the "Conversion Price"), subject to adjustment as described below.
The right to convert shares of PRIDES called for redemption will terminate
immediately before the close of business on the day prior to any redemption date
with respect to such shares.
 
     Conversion of shares of PRIDES at the option of the holder may be effected
by delivering certificates evidencing such shares of PRIDES, together with
written notice of conversion and, if required by the Company, a proper
assignment of such certificates to the Company or in blank (and, if applicable,
as provided in the following paragraph, cash payment of an amount equal to the
dividends attributable to the current quarterly dividend period payable on such
shares), to the office of the transfer agent for PRIDES or to any other office
or agency maintained by the Company for that purpose and otherwise in accordance
with conversion procedures established by the Company. Each optional conversion
will be deemed to have been effected immediately before the close of business on
the date on which the foregoing requirements have been satisfied. The conversion
will be at the Optional Conversion Rate in effect at such time and on such date.
 
     Holders of shares of PRIDES at the close of business on a record date for
any payment of declared dividends will be entitled to receive the dividend
payable on such shares of PRIDES on the corresponding dividend payment
notwithstanding the optional conversion of such shares of PRIDES following such
record date and on or before such dividend payment date. However, shares of
PRIDES surrendered for conversion
 
                                       74

<PAGE>   77
 
   
after the close of business on a record date for any payment of declared
dividends and before the opening of business on the next succeeding dividend
payment date must be accompanied by payment in cash of an amount equal to the
dividends attributable to the current quarterly dividend period payable on such
shares on such dividend payment date (unless such shares of PRIDES are subject
to redemption on a redemption date between such record date and such dividend
payment date). A holder of shares of PRIDES called for redemption on the Initial
Redemption Date or any other dividend payment date will receive the dividend on
such shares of PRIDES payable on that date and will be able to convert such
shares of PRIDES after the record date for such dividend without paying an
amount equal to such dividend to the Company upon conversion. Except as provided
above, upon any optional conversion of shares of PRIDES, the Company will make
no payment of or allowance for unpaid dividends, whether or not in arrears, on
such shares of PRIDES, or for previously declared dividends or distributions on
the shares of Common Stock issued upon such conversion.
    
 
   
     Enhanced Dividend Yield; Less Equity Appreciation than Common
Stock.  Dividends will accrue on the shares of PRIDES at the rate per annum of
$     (     % of the price per share to the public as set forth on the cover
page of this Prospectus). No dividends are currently paid on the Common Stock.
The opportunity for equity appreciation afforded by an investment in shares of
PRIDES is less than that afforded by an investment in Common Stock because the
Conversion Price is higher than the per share price to the public of the shares
of PRIDES and the Company may, at its option, redeem the shares of PRIDES at any
time on or after December 31, 1996, and before the Mandatory Conversion Date,
and may be expected to do so if, among other circumstances, the Current Market
Price of the Common Stock exceeds the Call Price for a share of PRIDES. In such
event, a holder of a share of PRIDES will receive less than one share of Common
Stock but no less than of a share of Common Stock. A holder may also surrender
for conversion any shares of PRIDES called for redemption up to the close of
business on the day prior to the redemption date, and a holder that so elects to
convert will receive of a share of Common Stock per share of PRIDES, subject to
adjustment as described herein. The value per share of PRIDES of the Common
Stock received by holders of shares of PRIDES may be more or less than the per
share amount paid for the shares of PRIDES offered hereby, due to market
fluctuations in the price of the Common Stock.
    
 
     As a result of these provisions, holders of shares of PRIDES would be
expected to realize no equity appreciation if the Current Market Price of the
Common Stock is below the Conversion Price, and less than all of such
appreciation if the Current Market Price of the Common Stock is above the
Conversion Price. Holders of shares of PRIDES will realize the entire decline in
equity value if the Current Market Price of the Common Stock is less than the
price paid for a share of PRIDES.
 
   
     Conversion Adjustments.  The Common Equivalent Rate and the Optional
Conversion Rate are each subject to adjustment if the Company shall (i) pay a
dividend or make a distribution with respect to Common Stock in shares of such
stock, (ii) subdivide or split its outstanding shares of Common Stock, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares,
(iv) issue by reclassification of its shares of Common Stock any shares of
common stock of the Company, (v) issue certain rights or warrants to all holders
of its Common Stock, or (vi) pay a dividend or make a distribution to all
holders of its Common Stock of evidences of its indebtedness or other assets
(including capital stock of the Company, but excluding any cash dividends or
distributions (other than Extraordinary Cash Distributions (as defined below))
and excluding any distributions and dividends referred to in clauses (i) through
(iv) above). In addition, the Company will also be entitled to make upward
adjustments in the Common Equivalent Rate, the Optional Conversion Rate or the
Call Price, as it shall in its discretion determine to be advisable, in order
that any stock dividends, subdivision or split of shares, distribution of rights
to purchase stock or securities, or distribution of securities convertible into
or exchangeable for stock (or any transaction which could be treated as any of
the foregoing transactions pursuant to Section 305 of the Code) hereafter made
by the Company to its stockholders will not be taxable. "Extraordinary Cash
Distributions" means, with respect to any cash dividend or distribution paid on
any date, the amount, if any, by which all cash dividends and cash distributions
on the Common Stock paid during the consecutive 12-month period ending on and
including such date (other than cash dividends and cash distributions for which
an adjustment to the Common Equivalent Rate and the Optional Conversion Rate was
previously made) exceeds, on a per share of Common Stock basis, 10% of the
    
 
                                       75

<PAGE>   78
 
   
average of the daily Closing Prices of the Common Stock over such consecutive
12-month period. All adjustments to the Common Equivalent Rate and the Optional
Conversion Rate will be calculated to the nearest 1/100th of a share of Common
Stock (with 5/1000th of a share being rounded to the next lower 1/100th of a
share). No adjustment in the Common Equivalent Rate or the Optional Conversion
Rate will be required unless such adjustment would require an increase or
decrease of at least 1% in such rate; provided, however, that any adjustments
which by reason of this provision are not required to be (and are not) made
shall be carried forward and taken into account in any subsequent adjustment.
    
 
   
     Whenever the Common Equivalent Rate and the Optional Conversion Rate are
adjusted as provided in the preceding paragraph, the Company will file with the
transfer agent for the shares of PRIDES a certificate with respect to such
adjustment, make a prompt public announcement thereof and mail a notice to
holders of the shares of PRIDES providing specified information with respect to
such adjustment. At least 10 days (or such shorter period as may be practicable
in the circumstances) before taking any action that could result in certain
adjustments in the Common Equivalent Rate and the Optional Conversion Rate, the
Company will mail a notice to holders of shares of PRIDES concerning such
proposed action.
    
 
   
     Adjustment for Certain Consolidations or Mergers.  In case of (i) any
consolidation or merger to which the Company is a party (other than a merger or
consolidation in which the Company is the surviving or continuing corporation
and in which the shares of Common Stock outstanding immediately before the
merger or consolidation remain unchanged and other than a merger or
consolidation with KACC (a "KACC Merger"), (ii) any sale or transfer to another
corporation of the property of the Company as an entirety or substantially as an
entirety, or (iii) any statutory exchange of securities with another corporation
(other than in connection with a merger or acquisition), each share of PRIDES
will, after consummation of such transaction, be subject to (A) conversion at
the option of the holder into the kind and amount of securities, cash, or other
property receivable upon consummation of such transaction by a holder of the
number of shares of Common Stock into which such share of PRIDES might have been
converted immediately before consummation of such transaction, (B) conversion on
the Mandatory Conversion Date into the kind and amount of securities, cash, or
other property receivable upon consummation of such transaction by a holder of
the number of shares of Common Stock into which such share of PRIDES would have
been converted if the conversion on the Mandatory Conversion Date had occurred
immediately before the date of consummation of such transaction, plus the right
to receive cash in an amount equal to all accrued and unpaid dividends on such
share of PRIDES (other than previously declared dividends payable to a holder of
record as of a prior date), and (C) redemption on any redemption date in
exchange for the kind and amount of securities, cash, or other property
receivable upon consummation of such transaction by a holder of the number of
shares of Common Stock that would have been issuable at the Call Price in effect
on such redemption date upon a redemption of such shares of PRIDES immediately
before consummation of such transaction, assuming that, if the Notice Date for
such redemption is not before such transaction, the Notice Date had been the
date of such transaction; and assuming in each case that such holder of shares
of Common Stock failed to exercise rights of election, if any, as to the kind or
amount of securities, cash, or other property receivable upon consummation of
such transaction (provided that, if the kind or amount of securities, cash, or
other property receivable upon consummation of such transaction is not the same
for each non-electing share, then the kind and amount of securities, cash or
other property receivable upon consummation of such transaction for each
non-electing share will be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). The kind and amount of
securities into or for which the shares of PRIDES will be convertible or
redeemable after consummation of such transaction will be subject to adjustment
as described above under the caption "Conversion Adjustments" following the date
of consummation of such transaction. The Company may not become a party to any
such transaction unless the terms thereof are consistent with the foregoing.
    
 
     Fractional Shares.  No fractional shares of Common Stock will be issued
upon redemption or conversion of the shares of PRIDES but, in lieu of any
fraction of a share of Common Stock which would otherwise be issuable in respect
of all shares of PRIDES surrendered by the same holder for redemption or
conversion on any date, the holder shall be entitled to receive an amount in
cash, out of funds of the Company legally available therefor, equal to the same
fraction of the (i) Current Market Price of the Common Stock determined as of
the second trading day immediately preceding the Notice Date, in the case of a
redemption,
 
                                       76

<PAGE>   79
 
or (ii) Closing Price of the Common Stock determined (A) as of the fifth trading
day immediately preceding the Mandatory Conversion Date, in the case of a
mandatory conversion, or (B) as of the second trading day immediately preceding
the effective date of conversion, in the case of an optional conversion by a
holder.
 
     Liquidation Rights.  Subject to the rights of holders of Series A Shares
and holders of any class or series of stock which the Company may in the future
issue which ranks senior to, or on a parity with, the PRIDES in respect of a
distribution of assets upon the liquidation, dissolution or winding-up of the
affairs of the Company, whether voluntary or involuntary (such event, a
"Liquidation"), the holders of the shares of PRIDES shall be entitled to receive
out of the assets of the Company available for distribution to stockholders,
whether from capital, surplus or earnings, before any distribution or payment is
made to holders of Common Stock of the Company or on any other class or series
of stock of the Company ranking junior as to assets distributable upon
Liquidation to the shares of PRIDES, for each share of PRIDES, an amount equal
to the sum of (i) the price to public for each share of PRIDES shown on the
cover page of this Prospectus and (ii) an amount equal to all accrued and unpaid
dividends thereon whether or not earned or declared (including dividends
accumulated and unpaid), to the date of Liquidation, but no more. If, upon any
Liquidation, there are insufficient assets to permit full payment to holders of
shares of PRIDES and to holders of any other class or series of stock ranking on
a parity with the PRIDES in respect of a distribution of assets upon
Liquidation, then such assets or proceeds thereof will be distributed among the
holders of PRIDES and any such other stock ratably in accordance with the
respective amounts which would be payable on such shares of PRIDES and any such
other stock if all amounts payable thereon were paid in full. Neither the
consolidation or merger of the Company with one or more corporations nor the
sale, lease or transfer by the Company of all or any part of its assets shall be
deemed a Liquidation.
 
   
     Voting Rights.  Holders of shares of PRIDES will have 4/5 vote for each
share held of record and, except as required by law, will be entitled to vote
together with the holders of Common Stock and together with the holders of any
other classes or series of stock (including the Series A Shares which are
entitled to 10 votes per Series A Share) who are entitled to vote in such manner
on all matters submitted to a vote of common stockholders. In addition, subject
to certain exceptions, the affirmative vote of two-thirds of the shares of
PRIDES actually voting (voting separately as a class) will be required to permit
the Company to (i) issue any class or series of stock, or any security
convertible at the option of the holder thereof into shares of any class or
series of stock, ranking senior to the PRIDES as to dividends or upon
Liquidation, (ii) modify the terms of the Intercompany Note in a manner that
materially adversely affects the Company as the holder of such Intercompany Note
or the holders of the PRIDES, (iii) amend the Certificate of Incorporation in a
manner that materially adversely affects the holders of the PRIDES, (iv)
consummate a KACC Merger if (a) each outstanding share of PRIDES, upon the
effectiveness of the KACC Merger, neither remains outstanding nor is converted
into one share of KACC Preferred Stock, (b) such shares of KACC Preferred Stock
(if issued in the KACC Merger) are not to be deposited with a bank or trust
company upon or prior to the effectiveness of the KACC Merger or (c) the
covenants in the debt instruments of the surviving corporation of the KACC
Merger, at the time of the KACC Merger, prohibit the payment of any of the
dividends on the PRIDES or the KACC Preferred Stock, as the case may be, in
accordance with the terms thereof through and including the day immediately
prior to the Mandatory Conversion Date or (v) consummate a merger or
consolidation of the Company with any other corporation, unless each holder of
shares of PRIDES immediately preceding such merger or consolidation receives or
continues to hold in the surviving corporation the same number of shares, with
substantially the same rights and preferences, (except as contemplated by the
provisions described under "Adjustments for Certain Consolidations or Mergers"),
as correspond to the shares of PRIDES so held. In the event of a KACC Merger for
which the consent of the holders of the PRIDES voting as a class is not
obtained, so long as any shares of PRIDES or KACC Preferred Stock, as the case
may be, remain outstanding, the surviving corporation of the KACC Merger shall
not thereafter amend its debt instruments so as to prohibit the payment of any
of the dividends on the PRIDES or KACC Preferred Stock, as the case may be, in
accordance with the terms thereof, without the consent of the holders of at
least two-thirds of the shares of shares of PRIDES or the KACC Preferred Stock,
as the case may be, voting thereon (voting separately as a class). The voting
provisions described above in this paragraph shall not apply if, at or prior to
the time of the act with respect to which a class vote of the PRIDES would
otherwise be required, (x) all outstanding shares of PRIDES are scheduled to be
redeemed or converted
    
 
                                       77

within two months, (y) sufficient shares of the Common Stock and cash, if any,
necessary for such redemption or conversion have been deposited with a bank or
trust company and (z) a KACC Merger is not consummated prior to such redemption
or conversion. In the event that dividends on the shares of PRIDES or any other
series of Preferred Stock are in arrears and unpaid for six quarterly dividend
periods, or if any series of Preferred Stock (other than the PRIDES) shall be
entitled for any other reason to exercise voting rights, separate from the
Common Stock, to elect any directors of the Company ("Preferred Stock
Directors"), the holders of the shares of PRIDES (voting separately as a class
with holders of all other series of Preferred Stock upon which like voting
rights have been conferred and are exercisable), with each share of PRIDES
entitled to one vote on this and other matters in which Preferred Stock votes as
a group, will be entitled to vote for the election of two directors of the
Company. Such right to elect two directors will continue until all dividends in
arrears and payable on the shares of PRIDES and such other series of Preferred
Stock have been paid in full and the right of any other series of Preferred
Stock to exercise voting rights, separate from the Common Stock, to elect
Preferred Stock Directors terminates. The term of office of any director elected
by the holders of the share of PRIDES and such other series will terminate on
the earlier of (i) the next annual meeting of stockholders at which a successor
shall have been elected and qualified or (ii) the termination of the right of
holders of the shares of PRIDES and such other series to vote for such
directors.
    
 
     Certain Procedures in connection with Redemption and Mandatory
Conversion.  Each holder of shares of PRIDES to be redeemed or to be converted
on the Mandatory Conversion Date must surrender the certificates evidencing such
shares to the Company at the place designated in the notice of such redemption
(or, in the case of a mandatory conversion, the principal executive offices of
the Company or at such other place as may be designated by the Company in a
written notice mailed to the holders of record of the PRIDES) and shall
thereupon be entitled to receive certificates evidencing shares of Common Stock
and cash, if any, payable on such redemption or conversion following such
surrender and following the date of such redemption or conversion. If (A) shares
of PRIDES are called for redemption and, on the date fixed for redemption,
shares of Common Stock necessary for the redemption shall have been deposited
with a bank or trust company as provided in the Certificate of Designations or
(B) shares of PRIDES have been converted on the Mandatory Conversion Date, then,
notwithstanding that the certificates evidencing any shares of PRIDES so called
for redemption or converted shall not have been surrendered, the shares
represented thereby so called for redemption or converted shall be deemed no
longer outstanding and all rights with respect to the shares so called for
redemption or converted shall forthwith cease and terminate, except for the
right of the holders to receive the shares of Common Stock and cash, if any,
payable on such redemption or conversion upon surrender of their certificates
therefor, provided, that holders of shares of PRIDES at the close of business on
a record date for any payment of dividends on shares of PRIDES shall be entitled
to receive the dividends payable on such shares on the corresponding dividend
payment date notwithstanding the redemption or conversion of such shares
following such record date and on or before such corresponding dividend payment
date. Holders of shares of PRIDES that are redeemed or that are converted on the
Mandatory Conversion Date shall not be entitled to receive dividends declared
and paid on shares of Common Stock issuable on such redemption or conversion,
and such shares of Common Stock shall not be entitled to vote, until such shares
of Common Stock are issued upon the surrender of the certificates representing
such shares of PRIDES and upon such surrender such holders shall be entitled to
receive such dividends declared and paid on such shares of Common Stock
subsequent to the redemption date or Mandatory Conversion Date, as applicable.
 
     Reissuance.  Shares of PRIDES redeemed for or converted into Common Stock
or otherwise acquired and retired by the Company will assume the status of
authorized but unissued Preferred Stock and may thereafter be reissued in the
same manner as other authorized but unissued Preferred Stock, but not as PRIDES.
 
     Miscellaneous.  Upon issuance, the shares of PRIDES will be fully paid and
nonassessable. The holders of PRIDES will have no preemptive rights. The
transfer agent and registrar for the PRIDES shares will be The First National
Bank of Boston.

                       FEDERAL INCOME TAX CONSIDERATIONS
 
   
     In the opinion of Kramer, Levin, Naftalis, Nessen, Kamin & Frankel, the
following sets forth the material United States federal income tax consequences
of the ownership and disposition of shares of PRIDES. Changes to existing law,
which could have retroactive effect, may alter the consequences described below.
This discussion relates only to shares of PRIDES or shares of Common Stock
received upon conversion thereof or in exchange therefor that are held as
capital assets within the meaning of Section 1221 of the Code and does not deal
with all tax consequences that may be relevant in the particular circumstances
of each holder (some of which, such as dealers in securities, insurance
companies, tax-exempt organizations and foreign persons, may be subject to
special rules). In addition, stock having terms closely resembling those of
shares of PRIDES have not been the subject of any regulation, ruling or judicial
decision currently in effect, and there can be no assurance that the Internal
Revenue Service will take the positions set forth below. The Company has not and
will not seek a ruling as to any tax matters relating to shares of PRIDES.
Persons considering the purchase of shares of PRIDES should consult their tax
advisors with respect to the application of the United States federal income tax
laws to their particular situations as well as any tax consequences arising
under the laws of any state, local or foreign taxing jurisdiction.
    
 
DIVIDENDS
 
     Dividends paid on shares of PRIDES out of the Company's current or
accumulated earnings and profits will be taxable as ordinary income and will
qualify for the 70% intercorporate dividends-received deduction subject to the
minimum holding period (generally at least 46 days, or 91 days in the case of
dividends attributable to periods aggregating more than 366 days) and other
applicable requirements. Under certain circumstances, a corporate holder may be
subject to the alternative minimum tax with respect to the amount of its
dividends-received deduction.
 
     Under certain circumstances, a corporation that receives an "extraordinary
dividend," as defined in Section 1059 of the Code, is required to reduce its
stock basis by the non-taxed portion of such dividend (generally, the portion
claimed as a dividend received deduction). Quarterly dividends not in arrears
paid to an original holder of shares of PRIDES will generally not constitute
extraordinary dividends under Section 1059(c). Under a special rule in Section
1059(f), any dividend with respect to "disqualified preferred stock" is treated
as an extraordinary dividend; however, while the issue is not free from doubt
due to the lack of authority directly on point, shares of PRIDES should not
constitute "disqualifed preferred stock."
 
REDEMPTION PREMIUM
 
     Under certain circumstances, Section 305 of the Code requires that any
excess of the redemption price of preferred stock over its issue price be
includable in income, prior to receipt, as a constructive dividend. However,
while the issue is not free from doubt due to a lack of authority directly on
point, a holder of shares of PRIDES should not be required to include any
redemption premium in income under Section 305 of the Code.
 
REDEMPTION OR CONVERSION INTO COMMON STOCK
 
     Gain or loss generally will not be recognized by a holder upon the
redemption of shares of PRIDES for shares of Common Stock or the conversion of
shares of PRIDES into shares of Common Stock if no cash is received. Dividend
income may be recognized, however, to the extent cash or Common Stock is
received in payment of accrued dividends. In addition, a holder who receives
cash in lieu of a fractional share will be treated as having received such
fractional share and having exchanged it for cash in a transaction subject to
Section 302 of the Code and related provisions. A holder who receives both
Common Stock and cash (other than any cash in lieu of a fractional share and
cash treated as dividend income as a result of payment of accrued dividends)
upon a conversion or redemption of shares of PRIDES into shares of Common Stock
will not recognize any loss and will recognize gain (if any) upon such
conversion or redemption, but not in excess of the amount of such cash. The
measure of such a holder's gain will be the excess (if any) of the sum of such
cash plus the value of the shares of Common Stock received (other than shares of
Common Stock taxed as a
 
                                       79

<PAGE>   82
 
dividend upon receipt) over such holder's adjusted tax basis in the converted
shares of PRIDES. Depending on the facts and circumstances, such gain might be
treated in whole or part as a dividend. Any such dividend to a corporate holder
might constitute an "extraordinary dividend" under Section 1059 of the Code,
with the result that certain regular dividends received by such holder might be
treated as "extraordinary." See "Federal Income Tax
Considerations -- Dividends."
 
     Generally, a holder's basis in the Common Stock received upon the
redemption or conversion of shares of PRIDES (other than shares of Common Stock
taxed as a dividend upon receipt) will equal the adjusted tax basis of the
redeemed or converted shares of PRIDES on the date of such redemption or
conversion plus the amount of gain recognized, minus the amount of cash
received, and the holding period of such Common Stock will include the holding
period of the redeemed or converted shares of PRIDES. If any shares of Common
Stock are taxed as a dividend on receipt, the holder's basis in such shares will
be their fair market value at the time of receipt, and the holding period for
such shares will begin on the date of their receipt.
 
SALE OF SHARES
 
     A holder who sells shares of PRIDES or Common Stock will recognize gain or
loss measured by the difference between the amount received in exchange for such
shares and such holder's tax basis in the shares (as determined under the rules
discussed above). In general, any gain or loss so recognized will be capital
gain or loss if the shares were held as a capital asset, and will be long-term
capital gain or loss if the holding period for such shares (determined under the
rules discussed above) exceeds one year.
 
ADJUSTMENT OF CONVERSION RATE
 
     Certain adjustments to the Common Equivalent Rate to reflect the Company's
issuance of certain rights, warrants, evidences of indebtedness, securities or
other assets to holders of Common Stock may result in constructive distributions
taxable as dividends to the holders of the shares of PRIDES, which may
constitute (and cause other dividends to constitute) "extraordinary dividends"
to corporate holders. See "Federal Income Tax Considerations -- Dividends."
 
BACKUP WITHHOLDING
 
     Certain noncorporate holders may be subject to backup withholding at a rate
of 31% on dividends and certain consideration received upon the redemption or
conversion of the shares of PRIDES. Generally, backup withholding applies only
when the taxpayer fails to furnish or certify a proper Taxpayer Identification
Number or when the taxpayer is notified by the Internal Revenue Service that the
taxpayer has failed to report payments of interest and dividends properly.
Holders should consult their tax advisors regarding their qualification for
exemption from backup withholding and the procedure for obtaining any applicable
exemption.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 100,000,000 shares
of Common Stock, and 20,000,000 shares of preferred stock, par value $.05 per
share (the "Preferred Shares"). The following is a summary of the material terms
of the capital stock of the Company, but does not purport to be complete or to
give full effect to the provisions of statutory or common law, and is subject in
all respects to the applicable provisions of the Certificate of Incorporation.
 
COMMON STOCK
 
     The Company is authorized by its Certificate of Incorporation to issue
100,000,000 shares of Common Stock, of which 58,095,599 shares were issued and
outstanding as of December 31, 1993.
 
     The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders. The Common Stock does
not have cumulative voting rights. Subject to the rights of holders of any
Preferred Shares, the holders of Common Stock are entitled to receive ratably
such
 
                                       80

<PAGE>   83
 
dividends as may be declared by the Board of Directors out of funds legally
available therefor. In the event of a liquidation, dissolution or winding up of
the Company, holders of Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities and the liquidation preference of any
then outstanding Preferred Shares. Holders of Common Stock have no preemptive,
conversion or redemption rights. All outstanding shares of Common Stock are duly
and validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
     General.  The Board of Directors has the authority (without action by the
stockholders) to issue the authorized and unissued Preferred Shares in one or
more classes or one or more series within any class thereof and to determine the
voting rights (including the right to vote as a class of series on particular
matters and elect directors in certain circumstances), preferences, conversion,
liquidation, dividend, and other rights of each such series. A total of
1,938,295 Preferred Shares were designated as Series A Shares in connection with
the June 1993 offering of $.65 Depositary Shares.
 
     The $.65 Depositary Shares and Series A Shares.  Each $.65 Depositary Share
represents ownership of one-tenth of a Series A Share deposited with The First
National Bank of Boston, as depositary, and entitles the owner to all of the
powers, preferences and rights of the Series A Shares represented thereby
(including the dividend, voting, liquidation and other rights thereof). The
Series A Shares are Preferred Shares and rank senior as to dividends and in
liquidation to the Company's Common Stock. The $.65 Depositary Shares convert
automatically into shares of Common Stock (upon the automatic conversion of the
Series A Shares) on June 30, 1996 (the "Mandatory Series A Conversion Date") or
earlier in the event of certain mergers, consolidations or similar extraordinary
transactions involving the Company. In addition, the Company has the option to
call the $.65 Depositary Shares (by calling the Series A Shares) for redemption,
in whole or in part, at any time or from time to time prior to the Mandatory
Series A Conversion Date, at the prescribed call price payable in shares of
Common Stock, plus an amount in cash equal to all accrued and unpaid dividends
payable with respect to such $.65 Depositary Shares.
 
                    If the $.65 Depositary Shares are not redeemed or converted
prior to the Mandatory Series A Conversion Date, the owners of $.65 Depositary
Shares will receive one share of Common Stock for each $.65 Depositary Share
(subject to adjustment for stock splits and certain other events) on the
Mandatory Series A Conversion Date. Although not obligated to do so, the Company
may be expected to call the $.65 Depositary Shares (by calling the Series A
Shares) prior to the Mandatory Series A Conversion Date if the market price for
the Common Stock exceeds the call price for the $.65 Depositary Shares, in which
event owners of $.65 Depositary Shares will receive less than one share of
Common Stock for each $.65 Depositary Share. The $.65 Depositary Shares are not
convertible into Common Stock at the option of holders thereof.
 
     Dividends.  The owners of $.65 Depositary Shares are entitled to receive
(when, as and if the Board of Directors declares dividends on the Series A
Shares) cumulative preferential cash dividends at the rate of $.65 per annum or
$.1625 per quarter for each of the $.65 Depositary Shares, payable quarterly in
arrears on the last day of each March, June, September and December, or, if any
such date is not a business day, on the next succeeding day that is a business
day. Dividends cease to accrue in respect of the $.65 Depositary Shares on the
earliest of (i) the day immediately prior to the Mandatory Series A Conversion
Date, (ii) the day immediately prior to the effective date of a merger,
consolidation or similar extraordinary transaction that results in an automatic
conversion (as described below) and (iii) the day immediately prior to the date
of redemption of any such shares. Except as otherwise set forth in the
Certificate of Designations governing the Series A Shares, accumulated unpaid
dividends do not bear interest.
 
     Mandatory Conversion.  On the Mandatory Series A Conversion Date, each
outstanding $.65 Depositary Share will convert automatically (upon the automatic
conversion of the Series A Shares) into one share of Common Stock (subject to
adjustment in the event of certain stock dividends or distributions,
subdivisions, splits, combinations, reclassifications, issuances of certain
rights or warrants or distributions of certain assets with respect to the Common
Stock), and the right to receive an amount in cash equal to all accrued and
unpaid dividends payable with respect to such $.65 Depositary Share to and
including the day immediately prior to the Mandatory Series A Conversion Date.
The Company has the right to call a portion or all of the
 
                                       81

<PAGE>   84
 
outstanding $.65 Depositary Shares (by calling the Series A Shares) prior to the
Mandatory Series A Conversion Date as described below.
 
                    In addition, immediately prior to the effectiveness of a
merger, consolidation or similar extraordinary transaction involving the Company
(other than a KACC Merger Event (as defined below)) that results in the
conversion or exchange of the Common Stock into, or results in the holders of
Common Stock having the right to receive, other securities or other property
(whether of the Company or any other entity) (any such merger, consolidation or
similar extraordinary transaction, a "Merger or Consolidation Event"), each
outstanding $.65 Depositary Share will automatically convert (upon the automatic
conversion of the Series A Shares) into (i) one share of Common Stock, subject
to adjustment in certain events, plus (ii) the right to receive an amount in
cash equal to the accrued and unpaid dividends payable with respect to such $.65
Depositary Share to and including the day immediately prior to the effective
date of such Merger or Consolidation Event, plus (iii) the right to receive an
amount in cash equal to $1.95 as of June 30, 1993, declining by $.0018 on each
day thereafter (computed on the basis of a 360-day year of twelve 30-day months)
to $.114 on April 30, 1996, and equal to zero thereafter. The Company may, at
its option, deliver, in lieu of some or all of the cash consideration described
in clauses (ii) and (iii) of the immediately preceding sentence, shares of
Common Stock. The number of shares of Common Stock to be delivered in lieu of
any cash consideration described in such clauses (ii) and (iii) will be
determined by dividing the amount of cash consideration that the Company has
elected to deliver in Common Stock by the Current Market Price (as defined) per
share of the Common Stock determined as of the second trading day immediately
preceding the Notice Date (as defined).
 
     Right to Call for Redemption.  At any time or from time to time prior to
the Mandatory Series A Conversion Date, the Company may call, in whole or in
part, the outstanding $.65 Depositary Shares (by calling the Series A Shares)
for redemption at a call price per $.65 Depositary Share initially equal to
$12.46 as of June 30, 1993, declining by $.0018 on each day thereafter (computed
on the basis of a 360-day year of twelve 30-day months) to $10.624 on April 30,
1996, and equal to $10.51 thereafter, payable in shares of Common Stock having
an aggregate Current Market Price equal to such call price, plus an amount in
cash equal to accrued and unpaid dividends payable with respect to such $.65
Depositary Shares, to and including the day immediately prior to the date of
redemption.
 
     Liquidation Rights.  The Series A Shares rank senior in right and priority
of payment to the Common Stock upon liquidation. Subject to the terms of any
stock ranking senior to, or on a parity with, the Series A Shares, the
liquidation preference applicable to each $.65 Depositary Shares (based on the
liquidation preference of the Series A Shares) is an amount equal to the sum of
(i) $7.25 and (ii) an amount equal to all accrued and unpaid dividends payable
with respect to such $.65 Depositary Shares.
 
     Voting Rights.  Holders of $.65 Depositary Shares (based on the voting
rights of the Series A Shares) have one vote for each $.65 Depositary Share held
of record and, except as required by law, are entitled to vote with the holders
of Common Stock on all matters submitted to a vote of common stockholders. In
addition, subject to certain exceptions, the affirmative vote of two-thirds of
the Series A Shares actually voting (voting separately as a class) is required
to permit the Company to (i) issue any class or series of stock ranking senior
to the Series A Shares as to dividends or upon liquidation, (ii) modify the
terms of a certain intercompany note (which provides funds to the Company to
enable the Company to make dividend payments on the Series A Shares) in a manner
that materially adversely affects the Company as the holder of such intercompany
note or the holders of the Series A Shares, (iii) amend its Certificate of
Incorporation in a manner that materially adversely affects the holders of the
Series A Shares, or (iv) consummate a merger or consolidation of the Company
with KACC (a "KACC Merger Event") if (a) each outstanding Series A Share, upon
the effectiveness of the KACC Merger Event, neither remains outstanding nor is
converted into one share of preferred stock of the surviving corporation ("KACC
Preferred Stock") identical as near as practicable to a Series A Share, (b) such
shares of KACC Preferred Stock (if issued in the KACC Merger Event) are not to
be deposited with a bank or trust company upon or prior to the effectiveness of
the KACC Merger Event, or (c) the covenants in the debt instruments of the
surviving corporation of the KACC Merger Event, at the time of the KACC Merger,
prohibit the payment of any of the dividends on the Series A Shares or the KACC
Preferred Stock, as the case may be, in accordance with the terms thereof
through and including
 
                                       82

<PAGE>   85
 
the day immediately prior to the Mandatory Series A Conversion Date. In the
event that dividends payable on the Series A Shares are in arrears in an
aggregate amount equivalent six full quarterly dividends, the holders of the
outstanding Series A Shares are entitled to elect, together with the holders of
all classes or series of stock ranking on a parity with the Series A Shares in
respect of dividends and upon which like voting rights in the event of a
dividend default with respect thereto have been conferred and are exercisable,
voting separately as a class, two directors of the Company.

     The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an additional 1,200,000
shares of PRIDES to cover over-allotments, if any, at the public offering price
set forth on the cover page of this Prospectus, less the underwriting discount.
If the Underwriters exercise this option, each of the Underwriters will have a
firm commitment, subject to certain conditions, to purchase approximately the
same percentage thereof which the number of shares of PRIDES to be purchased by
it shown in the foregoing table is of the 8,000,000 shares of PRIDES initially
offered hereby.
    
 
     The Underwriters have advised the Company that they propose to offer the
shares of PRIDES to the public at the offering price set forth on the cover page
of this Prospectus, and to certain dealers at such price less a concession not
in excess of $     per share. The Underwriters may allow, and such dealers may
reallow, a discount not in excess of $     per share on sales to certain other
dealers. After the initial public offering, the public offering price,
concession and discount may be changed.
 
   
     The Company has agreed that during a period of 90 days from the date of the
Prospectus, the Company will not, without the prior written consent of Merrill
Lynch, directly or indirectly, offer to sell, sell, grant any option for the
sale of, or otherwise issue or dispose of any shares of PRIDES, $.65 Depositary
Shares, Series A Shares or Common Stock, or any securities similar thereto, or
any security convertible into or exchangeable or exercisable for any such
securities or any such similar securities, except (i) offers to sell and sales
to the Underwriters pursuant to the offering, (ii) the issuance of a certain
number of shares of Common Stock pursuant to employee benefit arrangements of
the Company and (iii) the issuance of Common Stock upon the conversion or
redemption of Series A Shares or shares of PRIDES. In addition, MAXXAM has
agreed that it will not, and it will not permit any of its subsidiaries (other
than the Company and its subsidiaries) (each, a "MAXXAM Subsidiary") to, without
the prior written consent of Merrill Lynch, directly or indirectly, offer to
sell, sell, grant any option for the sale of or otherwise dispose of any (a)
shares of PRIDES or Common Stock, or any security (other than $.65 Depository
Shares and Series A Shares) convertible into or exchangeable or exercisable for

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and the Board of Directors of
  Kaiser Aluminum Corporation:
 
     We have audited the accompanying consolidated balance sheets of Kaiser
Aluminum Corporation (a Delaware corporation) and subsidiaries as of December
31, 1992 and 1991, and the related statements of consolidated income and cash
flows for each of the three years in the period ended December 31, 1992. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Kaiser Aluminum Corporation
and subsidiaries as of December 31, 1992 and 1991, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1992, in conformity with generally accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements include the statements of Kaiser
Aluminum Corporation ("Kaiser" or the "Company") and its majority-owned
subsidiaries. Investments in 50%-or-less-owned entities are accounted for
primarily by the equity method. Intercompany balances and transactions are
eliminated. The Company is an indirect subsidiary of MAXXAM Inc. ("MAXXAM"), and
conducts its operations through its wholly owned subsidiary, Kaiser Aluminum &
Chemical Corporation ("KACC"). Certain reclassifications of prior year
information were made to conform to the current presentation.
 
  Cash and Cash Equivalents
 
     The Company considers only those short-term, highly liquid investments with
original maturities of 90 days or less to be cash equivalents.
 
  Inventories
 
     Substantially all product inventories are stated at last-in, first-out
("LIFO") cost, not in excess of market. Replacement cost is not in excess of
LIFO cost. Other inventories, principally operating supplies and repair and
maintenance parts, are stated at the lower of average cost or market. Inventory
costs consist of material, labor, and manufacturing overhead, including
depreciation. Inventories consist of the following:

</TABLE>

 
     The Company recorded a pre-tax charge of approximately $29.0 in the fourth
quarter of 1992 because of a reduction in the carrying value of its inventories
caused principally by prevailing lower prices for alumina, primary aluminum, and
fabricated products of $18.8, and a LIFO inventory liquidation of $10.2.
 
  Depreciation
 
     Depreciation is computed principally by the straight-line method at rates
based upon the estimated useful lives of the various classes of assets. The
principal estimated useful lives by class of assets are:

  Recognition of Certain Sales
 
     In 1989, KACC entered into a forward alumina sales transaction to sell
forward alumina at fixed prices through 1992. A portion of the selling price was
received in the form of an initial payment of approximately $179.9, which
approximately equaled the expected cash profit margin for the sale, discounted
to present value. The initial payment has been recognized as revenue as the
alumina was delivered. At December 31, 1992, substantially all of the initial
payment has been recognized as revenue.

                 (IN MILLIONS OF DOLLARS, EXCEPT SHARE AMOUNTS)
 
  Other Income
 
     Included in other income in 1992 are approximately $14.0 of pre-tax income
for non-recurring adjustments to previously recorded liabilities and reserves in
the fourth quarter. Included in interest and other income in 1991 is the receipt
of a $12.0 fee in the first quarter from the Company's minority partner in
consideration for the execution of an expansion agreement for the Alumina
Partners of Jamaica ("Alpart") alumina refinery. The agreement provides for a
program of expansion and modernization of Alpart at the existing ownership
interest of 65% for KACC and 35% for KACC's minority partner. The prior
expansion agreement provided for expansion rights of 75% for KACC and 25% for
KACC's minority partner.
 
  Futures Contracts and Options
 
     The Company periodically enters into forward foreign exchange, commodity
futures, and commodity option contracts, which are primarily accounted for as
hedges of its revenues and costs. The gains and losses on these contracts are
reflected in earnings concurrently with the hedged revenues or costs. The cash
flows from these contracts are classified in a manner consistent with the
underlying nature of the transactions. At December 31, 1992, the Company has
contracts to purchase $18.3 of pounds sterling and $8.4 of Australian dollars at
various fixed rates expiring on various dates through December 31, 1993.
 
     The Company is entitled to withdraw the excess of current market value over
the premiums paid on certain commodity option contracts. These withdrawals were
$3.7 and $70.0 at December 31, 1992 and 1991, respectively, and are included in
other accrued liabilities.
 
  Deferred Financing Costs
 
     Costs incurred to obtain financing are deferred and amortized over the
estimated term of the related borrowing.
 
  Foreign Currency
 
     The Company uses the United States dollar as the functional currency for
its foreign operations.
 
  Fair Value of Financial Instruments
 
     Unless otherwise disclosed, the carrying amount of all financial
instruments is a reasonable estimate of fair value.
 
  Net Income per Common Share
 
     Net income per share calculations for 1992 and 1991 were based on the
57,250,423 and 53,297,260 weighted average number of common shares,
respectively. During the year ended December 31, 1990, the Company's common
stock was not publicly traded, and there were no common stock equivalents
outstanding. Earnings per share calculation for that year was based on
50,000,000 shares issued.
 
2. INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED AFFILIATES
 
     Summary combined financial information is provided below for unconsolidated
aluminum investments, most of which supply and process raw materials. The
investees are Queensland Alumina Limited ("QAL") (28.3% owned), Anglesey
Aluminium Limited ("Anglesey") (49.0% owned), and Kaiser Jamaica Bauxite Company
(49.0% owned). The equity in earnings (losses) before income taxes of such
operations are treated as a reduction (increase) in cost of products sold. At
December 31, 1992 and 1991, KACC's net receivables from these affiliates were
not material.

</TABLE>

 
     The Company's equity in losses differs from the summary net income (loss)
due to various percentage ownerships in the entities and equity method
accounting adjustments.
 
     At December 31, 1992, KACC's investment in its unconsolidated affiliates
exceeded its equity in their net assets by approximately $49.8. The Company is
amortizing this amount over a 12-year period, which results in an annual
amortization charge of approximately $7.6.
 
     The Company and its affiliates have interrelated operations. The Company
provides some of its affiliates with services such as financing, management, and
engineering. Significant activities with affiliates include the acquisition and
processing of bauxite, alumina, and primary aluminum. Purchases from these
affiliates were $219.4, $238.7, and $228.2 in the years ended December 31, 1992,
1991, and 1990, respectively. No dividends were received from investees in the
three years ended December 31, 1992.

  The 1989 Credit Agreement
 
     The Company and KACC entered into a credit agreement with a syndicate of
commercial banks and other financial institutions (the "Banks") pursuant to the
terms of which the Banks agreed to extend to KACC credit facilities in an
aggregate principal amount of approximately $722.0 (as amended, "the 1989 Credit
Agreement"). The obligations of KACC in respect of the credit facilities are
guaranteed by Kaiser, and by a number of wholly owned subsidiaries of KACC,
which, among other things, together directly own the Company's interest in
Alpart and QAL. Loans under the 1989 Credit Agreement bear an annual interest
rate, at KACC's election from time to time, equal to (i) the Reference Rate
(prime) plus 1 1/2%, (ii) the CD Rate plus 2 5/8%, or (iii) the LIBO Rate plus
2 1/2%. All interest rates and fees are subject to a reduction or increase of
 1/2% per annum, on a non-cumulative basis, depending upon KACC's interest
coverage ratio, determined quarterly. As of December 31, 1992, the interest
coverage ratio permitted no reduction or increase in interest rates and fees.
 
     The 1989 Credit Agreement requires KACC to maintain certain financial
covenants and places restrictions on KACC's ability to, among other things,
incur debt and liens, make investments, pay dividends,

undertake transactions with affiliates, make capital expenditures, and enter
into unrelated lines of business. Payment of dividends by KACC to Kaiser is
subject to meeting certain conditions. As of December 31, 1992, $20.6 was
available for payment of dividends, although under the terms of the 1989 Credit
Agreement, no more than $3.0 may be paid in any quarter. The 1989 Credit
Agreement requires KACC to prepay certain outstanding amounts from proceeds from
Asset Dispositions, as defined, and to prepay certain amounts outstanding in an
amount equal to 50% of Excess Cash Flow, as defined, for each fiscal year ending
on or after December 31, 1990. The 1989 Credit Agreement is secured by, among
other things, (i) mortgages on KACC's major domestic plants; (ii) subject to
certain exceptions, liens on the accounts receivable, inventory, equipment,
domestic patents and trademarks, and substantially all other personal property
of KACC and certain of its subsidiaries; (iii) a pledge of all the stock of KACC
owned by Kaiser; and (iv) pledges of all of the stock of a number of KACC's
wholly owned subsidiaries, pledges of a portion of the stock of certain foreign
subsidiaries, and pledges of a portion of the stock of certain partially owned
foreign affiliates.
 
     The 1989 Credit Agreement comprises the following:
 
        Revolving Credit Facility -- The five-year Revolving Credit Facility
        provides for loans not to exceed the lesser of $350.0 or a borrowing
        base relating to the amount of eligible accounts receivable and eligible
        inventory of KACC and certain of its subsidiaries. Up to $50.0 of
        availability under the Revolving Credit Facility may be used for letters
        of credit. During each year the Revolving Credit Facility is
        outstanding, KACC is required to maintain $50.0 in unutilized capacity
        for a minimum of thirty consecutive days. As of December 31, 1992, $24.0
        (of which $14.0 may be used for letters of credit) was available to KACC
        under the Revolving Credit Facility.
 
        Term Loan -- The five-year Term Loan was originally to be repaid in ten
        equal semi-annual installments, commencing May 31, 1990. Following an
        amendment, the 1989 Credit Agreement requires, among other things, the
        mandatory prepayment, no later than July 29, 1993, of all amounts
        outstanding under the Term Loan.
 
     The Company expects that it will be able to satisfy its debt service and
capital expenditures requirements through at least March 31, 1994, from cash
flows generated by operations and, to the extent necessary, from borrowings
under the revolving credit facility of the 1989 Credit Agreement. The Company
believes that it will be able to renegotiate and/or refinance the 1989 Credit
Agreement as necessary prior to its expiration.
 
  Gramercy Revenue Bonds
 
     In December 1992, KACC entered into an installment sale agreement (the
"Sale Agreement") with the Parish of St. James, Louisiana (the "Louisiana
Parish"), pursuant to which the Louisiana Parish issued $20.0 aggregate
principal amount of its 7 3/4% Bonds due August 1, 2022 (the "Bonds") to finance
the construction of certain solid waste disposal facilities at KACC's Gramercy
plant. The proceeds from the sale of the Bonds were deposited into a
construction fund and may be withdrawn, from time to time, pursuant to the terms
of the Sale Agreement and the Bond indenture. At December 31, 1992, $17.4
remained in the construction fund. The Sale Agreement requires KACC to make
payments to the Louisiana Parish in installments due on the dates and in the
amounts required to permit the Louisiana Parish to satisfy all of its payment
obligations under the Bonds.
 
  Senior Subordinated Notes
 
     On February 1, 1993, KACC issued $400.0 of 12 3/4% Senior Subordinated
Notes due 2003 (the "12 3/4% Notes"). The net proceeds from the sale of the
12 3/4% Notes were used to retire the 14 1/4% Senior Subordinated Notes due 1995
(the "14 1/4% Notes"), to prepay $18.0 of the Term Loan, and to reduce
outstanding borrowings under the Revolving Credit Facility. These transactions
will result in a pre-tax

extraordinary loss of approximately $33.0 in the first quarter of 1993,
consisting primarily of the write-off of unamortized discount and deferred
financing costs related to the 14 1/4% Notes and the tender premium on the
14 1/4% Notes.
 
     The obligations of KACC with respect to the 12 3/4% Notes are guaranteed,
jointly and severally, by certain subsidiaries of KACC. The indenture governing
the 12 3/4% Notes contains, among other things, restrictions on the ability of
KACC and its subsidiaries to incur debt, undertake transactions with affiliates,
and pay dividends.
 
  Alpart CARIFA Loan
 
     In December 1991, Alpart entered into a loan agreement with the Caribbean
Basin Projects Financing Authority ("CARIFA") under which CARIFA loaned Alpart
the proceeds from the issuance of CARIFA's industrial revenue bonds. The terms
of the loan parallel the bonds' repayment terms. The $38.0 aggregate principal
amount of Series A bonds matures on June 1, 2008. The Series A bonds bear
interest at a floating rate of 87% of the applicable LIBID rate (LIBOR less 1/8
of 1%) on $37.5 of the principal amount (3.4% at December 31, 1992) with the
remaining $.5 bearing interest at a fixed rate of 6.35%. The $22.0 aggregate
principal amount of Series B bonds matures on June 1, 2007, and bears interest
at a fixed rate of 8.25%.
 
     Proceeds from the sale of the bonds were used by Alpart to refinance
interim loans from the partners in Alpart, to pay eligible project costs for the
expansion and modernization of its alumina refinery and related port and bauxite
mining facilities, and to pay certain costs of issuance. Under the terms of the
loan agreement, Alpart must remain a qualified recipient for Caribbean Basin
Initiative funds as defined in applicable laws. Alpart has agreed to indemnify
bondholders of CARIFA for certain tax payments that could result from events, as
defined, that adversely affect the tax treatment of the interest income on the
bonds. Alpart's obligations under the loan agreement are secured by a $64.2
letter of credit guaranteed by the partners in Alpart (of which $22.5 is
guaranteed by the Company's minority partner in Alpart).
 
  Capitalized Interest
 
     Interest capitalized in 1992, 1991, and 1990 was $4.4, $4.2, and $8.9,
respectively.
 
  Restricted Net Assets of Subsidiary
 
     At December 31, 1992, certain debt instruments restricted the ability of
KACC to transfer assets, make loans and advances, and pay dividends to the
Company. The restricted net assets of KACC totaled $547.8 at December 31, 1992.
 
  Fair Value Disclosure
 
     The fair value of the Company's long-term debt at December 31, 1992, is as
follows:
 
        -- The estimated fair value of the 14 1/4% Notes is the amount used to
          retire the 14 1/4% Notes in February 1993, or $347.8.
 
        -- The fair value of all other long-term debt is estimated to be $459.0
          based upon discounting the future cash flows using the current rate
          for debt of similar maturities and terms.

     In the years ended December 31, 1992 and 1991, the Company has reversed
$2.9 and $8.7 of previously established income tax reserves.
 
     The Company and its subsidiaries are included in the consolidated federal
income tax return of MAXXAM. KACC and MAXXAM entered into a tax allocation
agreement (the "KACC Tax Allocation Agreement") which became effective as of
October 28, 1988. Under the terms of the KACC Tax Allocation Agreement, MAXXAM
will compute the federal income tax liability for KACC and its subsidiaries
(collectively, the "Subgroup") as if the Subgroup were a separate affiliated
group of corporations which was never connected with MAXXAM. During 1991, the
Company and MAXXAM entered into a tax allocation agreement (the "Company Tax
Allocation Agreement") which became effective as of January 1, 1991. Under the
terms of the Company Tax Allocation Agreement, MAXXAM will compute a tentative
federal income tax liability for the Company as if it and its subsidiaries,
including KACC and its subsidiaries, were a separate affiliated group of
corporations which was never connected with MAXXAM. The federal income tax
liability of the Company will be the difference between the tentative federal
income tax liability and the liability computed under the KACC Tax Allocation
Agreement. The 1989 Credit Agreement prohibits the payment by KACC to MAXXAM of
any amount due under the KACC Tax Allocation Agreement until December 15, 1994.
 
     Income taxes are classified as either domestic or foreign, based on whether
payment is made or due to the United States or a foreign country. Certain income
classified as foreign is also subject to domestic income taxes.
 
     At December 31, 1992, the Company has approximately $1.8 of regular tax
foreign tax credit carryforwards and approximately $31.5 of alternative minimum
tax foreign tax credit carryforwards which expire through 1994. These tax
attributes are available to reduce future federal tax provisions for financial

     The above tax attributes are subject to various limitations.
 
     In February 1992, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards No. 109, Accounting for
Income Taxes ("SFAS 109"). The Company elected to adopt SFAS 109 as of January
1, 1993. The cumulative effect of the change in accounting principle for the
adoption of SFAS 109 will be recorded as a charge to operations and will reduce
results of operations by approximately $2.0. The implementation of SFAS 109 will
require the Company to restate certain assets and liabilities to their pre-tax
amounts from their net-of-tax amounts originally recorded. The adoption of SFAS
109, including the restatement of certain assets and liabilities, will primarily
result in an increase in the net carrying value of property, plant, and
equipment, an increase in long-term liabilities, and an increase in deferred
income tax liabilities. Concurrent with the adoption of SFAS 109, the Company
will implement the change in accounting method for postretirement benefits as
discussed in Note 6. This accounting method change will result in the
recognition of a deferred tax asset of approximately $234.0. The Company
believes that its ability to generate future taxable income will allow for the
realization of this deferred tax asset.

     Statement of Financial Accounting Standards No. 87, Employers' Accounting
for Pensions, requires recognition of a minimum pension liability for unfunded
plans. At December 31, 1992, the Company recorded an after-tax charge to equity
of $6.7 because the additional liability required to be recognized exceeded
unrecognized prior service cost (see Note 7).

  Incentive Plans
 
     Effective January 1, 1989, the Company and KACC adopted an unfunded
Long-Term Incentive Plan (the "LTIP") for certain key employees of the Company,
KACC, and their consolidated subsidiaries. Substantially all compensation vested
under the LTIP, as amended in 1991 and 1992, has been paid to the participants
in cash or common stock of the Company as of December 31, 1992. Under the LTIP,
as amended, amounts earned and unvested of approximately $6.1 will vest at the
rate of 25% per year for the four-year period ending December 31, 1996. All
future payments from the LTIP are expected to be in common stock of the Company.
 
     Effective January 1, 1990, KACC adopted an unfunded Middle Management
Long-Term Incentive Plan. KACC also has a supplemental savings and retirement
plan for salaried employees under which the participants contribute a percentage
of their base salaries.
 
     The Company's expense for the above plans was $6.6, $6.5, and $15.0 for the
years ended December 31, 1992, 1991, and 1990, respectively.
 
  Postretirement Benefits
 
     The Company and its subsidiaries provide postretirement health care and
life insurance benefits to retired employees. Substantially all employees may
become eligible for those benefits if they reach retirement age while still
working for the Company or its subsidiaries. Those benefits are provided through
administrative service contracts with various insurance carriers. The Company or
its subsidiaries pay and expense the cost of providing these benefits as
incurred. The cost of these benefits was $47.2, $40.2, and $40.0 for the years
ended December 31, 1992, 1991, and 1990, respectively.
 
     In December 1990, the FASB issued Statement of Financial Accounting
Standards No. 106, Employers' Accounting for Postretirement Benefits Other Than
Pensions ("SFAS 106"), which requires that the expected cost of providing
postretirement health care and life insurance benefits be charged to expense
during the years that the employees render service. This is a significant change
from the Company's current policy of

recognizing these costs on a cash basis. The Company has elected to adopt SFAS
106 as of January 1, 1993. The cumulative effect of the change in accounting
principle for the adoption of SFAS 106 will be recorded as a charge to results
of operations and will reduce pre-tax results of operations by $732.0. The tax
benefit for the adoption of SFAS 106 which will be recorded under SFAS 109,
based upon the current statutory rate, is approximately $234.0. In addition, the
Company estimates that annual 1993 postretirement benefit pre-tax expense will
be approximately $18.4 higher than would have been reported under the current
policy. The new accounting method has no effect on the Company's cash outlays
for retiree benefits nor will the one-time charge affect the Company's
compliance with its existing debt covenants. The Company reserves the right,
subject to applicable collective bargaining agreements, to amend or terminate
these benefits.
 
  Postemployment Benefits
 
     In November 1992, the FASB issued Statement of Accounting Standards No.
112, Employers' Accounting for Postemployment Benefits ("SFAS 112"). SFAS 112
requires employers to recognize the obligation to provide postemployment
benefits to former or inactive employees. The Company provides certain benefits
to former or inactive employees after employment but before retirement. The
Company has elected to adopt SFAS 112 as of January 1, 1993. The cumulative
effect of the change in accounting principle for the adoption of SFAS 112 will
reduce pre-tax results of operations by approximately $10.0 to $15.0. In
addition, the Company believes that annual 1993 postemployment benefit expenses
will not be materially different than would have been reported under the current
policy. The new accounting method has no effect on the Company's cash outlays
for postemployment benefits nor will it affect the Company's compliance with its
existing debt covenants. The Company reserves the right, subject to applicable
collective bargaining agreements and applicable legal requirements, to amend or
terminate these benefits.

Steelworkers of America (USWA) whereby shares of a new series of "Cumulative
(1985 Series A) Preference Stock" would be issued to an employee stock ownership
plan in exchange for certain elements of wages and benefits. Concurrently, a
similar plan was established for certain nonbargaining employees which provided
for the issuance of "Cumulative (1985 Series B) Preference Stock." Series A

value of $50 per share plus accrued dividends, if any.
 
     For financial reporting purposes, Series A and B Stock were recorded at
fair market value when issued, based on independent appraisals, with a
corresponding charge to compensation cost. Carrying values have been increased
each year to recognize accretion of redemption values and, in certain years,
there have been other increases for reasons described below. Issuances and
redemptions of Series A and B Stock are shown below.

     No additional Series A or B Stock will be issued based on compensation
earned in 1992 or subsequent years. While held by the plan trustee, Series B
Stock is entitled to cumulative annual dividends, when and as declared by the
Board of Directors, payable in stock or in cash at the option of KACC on or
after March 1, 1991, in respect to years commencing January 1, 1990, based on a
formula tied to KACC's income before tax from aluminum operations. When
distributed to plan participants (generally upon separation from KACC), the
Series A and B stocks are entitled to an annual cash dividend of $5 per share,
payable quarterly, when and as declared by the Board of Directors.
 
     Redemption fund agreements require KACC to make annual payments by March 31
each year based on a formula tied to consolidated net income until the
redemption funds are sufficient to redeem all Series A and B Stock. On an annual
basis, the minimum payment is $4.3 and the maximum payment is $7.3. In April
1988, KACC entered into a two-and-one-half-year agreement with the USWA whereby
KACC was obligated to make additional contributions to the Series A redemption
fund of (i) $2.0 each in March 1989 and 1990; and (ii) an additional amount
equal to 8.5% of the redemption value of all shares of Series A Stock
distributed from the trust occasioned by the sale of any plant covered by the
agreement to the extent there was not enough money in the redemption fund to
redeem the shares presented for payment. As a result of this agreement, KACC
also agreed with the USWA to contribute $22.5 to the Series A redemption fund in
conjunction with the sale of Ravenswood. In March 1991 and 1992, KACC
contributed $7.1 and $7.0 for the years 1990 and 1991, respectively, and will
contribute $4.3 in March 1993 for 1992.
 
     Under the USWA labor contract effective November 1, 1990, KACC was
obligated to offer to purchase up to 80 shares of Series A Stock from each
active participant in 1991 at a price equal to its redemption value of $50 per
share. KACC also agreed to offer to purchase up to an additional 40 shares from
each participant in 1994. The employees may elect to receive their shares,
accept cash, or place the proceeds into KACC's 401(k) savings plan. Under
separate action, KACC also offered to purchase 80 shares of Series B stock from
active participants in 1991. In 1991, KACC purchased $11.1 of Series A stock and
$2.1 of Series B stock. If the remaining shares of Series A stock are purchased
by the Company, the purchases will total $4.1 in 1994.
 
     The Series A and B Stock is distributed in the event of death, retirement,
or in other specified circumstances. KACC may also redeem such stock at $50 per
share plus accrued dividends, if any. At the option of the plan participant, the
trustee shall redeem stock distributed from the plans at redemption value to the
extent funds are available in the redemption fund. Under the Tax Reform Act of
1986, at the option of the plan participant, KACC must purchase distributed
shares earned after December 31, 1985, at redemption

value on a five-year installment basis, with interest at market rates. The
obligation of KACC to make such installment payments must be secured.
 
     The Series A and B Stock is entitled to the same voting rights as KACC
common stock and to certain additional voting rights under certain
circumstances, including the right to elect, along with other KACC preference
stockholders, two directors whenever accrued dividends have not been paid on two
annual dividend payment dates, or when accrued dividends in an amount equivalent
to six full quarterly dividends are in arrears. The Series A and B Stock
restricts the ability of KACC to redeem or pay dividends on common stock if KACC
is in default on any dividends payable on the Series A and B Stock.

     KACC Cumulative Convertible Preference Stocks, $100 par value ("$100
Preference Stocks"), restrict acquisition of junior stock and payment of
dividends. At December 31, 1992, such provisions were less restrictive as to the
payment of cash dividends than the 1989 Credit Agreement provisions. KACC has
the option to redeem the $100 Preference Stocks at par value plus accrued
dividends. KACC does not intend to issue any additional shares of the $100
Preference Stocks.
 
     The 4 1/8% and 4 3/4% (1957 Series, 1959 Series, and 1966 Series) $100
Preference Stocks can be exchanged for per share cash amounts of $69.30, $77.84,
$78.38, and $76.46, respectively. KACC records the $100 Preference Stocks at
their exchange amounts for financial statement presentation.
 
  Common Stock
 
     On July 18, 1991, the Company issued 7,250,000 shares, or approximately
12.7% of its common stock, for net proceeds of approximately $93.2.
Approximately 87.2% of Kaiser's common stock continues to be held indirectly by
MAXXAM and the remaining .1% of common stock is owned by management (see Note
6). Three-fourths of the net proceeds from the offering were used by the Company
to prepay a portion of the promissory notes of the Company (see "Dividends"
below) with accrued interest, payable to its parent. The remaining balance of
such notes payable to parent that were not prepaid with the net proceeds of the
offering, together with accrued interest, were contributed to the stockholders'
equity of the Company. The remaining one-fourth of the net proceeds from the
offering was used by Kaiser to purchase common stock of KACC. KACC reduced its
Term Loan by an amount equal to the proceeds it received from Kaiser.
 
     At December 31, 1992, 25,945,946 shares of Kaiser's common stock held
indirectly by MAXXAM are pledged as security for $150.0 of notes issued in
November 1991 by a MAXXAM subsidiary.
 
  Dividends
 
     In December 1990, the Company declared a dividend on common stock of $150.0
in the form of promissory notes (see "Common Stock" above). On January 31,
September 16, and December 16, 1991, the

Company declared and paid dividends on common stock of $50.0, $2.9, and $2.8,
respectively. The Company paid cash dividends on common stock of $2.9 in each
quarter of 1992. In the event that the Company pays any distributions to its
shareholders, the 1989 Credit Agreement requires MAXXAM and any subsidiary of
MAXXAM to use the entire proceeds of any such distributions received by MAXXAM
or any subsidiary of MAXXAM to purchase a Pay-in-Kind Note (the "PIK Note") from
KACC. On December 15, 1992, KACC issued a PIK Note to a subsidiary of MAXXAM in
the principal amount of $2.5, representing the entire amount of the dividend
received by such subsidiary in respect of the shares of the Company's common
stock which it owns. The PIK Note bears interest, compounded semiannually, at a
rate equal to 12% per annum, and is due and payable, together with accrued
interest thereon, on June 30, 1995.
 
8. COMMITMENTS AND CONTINGENCIES
 
     The Company has financial commitments, including purchase agreements,
tolling arrangements, forward foreign exchange contracts, forward sales
contracts, letters of credit, and guarantees.
 
     Purchase agreements and tolling arrangements include agreements to supply
alumina to Anglesey and to purchase aluminum from that company.
 
     Similarly, KACC has long-term agreements for the purchase and tolling of
bauxite into alumina in Australia by QAL. These obligations expire in 2008.
Under the agreements, KACC is unconditionally obligated to pay its proportional
share of debt, operating costs, and certain other costs of QAL. The aggregate
minimum amount of required future principal payments at December 31, 1992, is
$70.7, due in 1997. The KACC share of payments, including operating costs and
certain other expenses under the agreement, was $99.2, $107.6, and $88.9 for the
years ended December 31, 1992, 1991, and 1990, respectively.
 
     Minimum rental commitments under operating leases at December 31, 1992, are
as follows: years ending December 31, 1993 -- $20.4; 1994 -- $19.3; 1995 --
$18.4; 1996 -- $18.0; 1997 -- $17.4; thereafter -- $261.7. The future minimum
rentals receivable under noncancelable subleases were $94.5 at December 31,
1992.
 
     Rental expenses were $26.2, $23.3, and $23.1 for the years ended December
31, 1992, 1991, and 1990, respectively.
 
     Primarily included in other long-term liabilities are environmental
accruals related to potential solid waste disposal and soil and groundwater
remediation matters. The following table presents the changes in such accruals
for the years ended December 31, 1992, 1991, and 1990:

     The Company is involved in various claims, lawsuits, and other proceedings
relating to product liability, environmental protection, and a wide variety of
other matters. While uncertainties are inherent in the ultimate outcome of such
matters and it is impossible to determine the costs that ultimately may be
incurred, management believes that the resolution of such uncertainties and the
incurrence of such costs, some of which may be substantial, should not have a
material adverse effect upon the Company's consolidated financial position or
results of operations.

     Sales and transfers among geographic areas are made on a basis intended to
reflect the market value of products.
 
     The aggregate foreign currency gain included in determining net income was
$12.0, $1.2, and $7.2 for the years ended December 31, 1992, 1991, and 1990,

               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
                 (IN MILLIONS OF DOLLARS, EXCEPT SHARE AMOUNTS)
1. GENERAL
 
     The foregoing unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X as promulgated by the Securities and Exchange Commission.
Accordingly, said financial statements do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments necessary
for a fair statement of the results for the interim periods presented have been
included. Operating results for the first nine months of 1993 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 1993. Certain reclassifications of prior period information were
made to conform to the current presentation.
 
     Kaiser Aluminum Corporation ("Kaiser" or the "Company") is a 68%-owned
subsidiary of MAXXAM Inc. ("MAXXAM"). The remaining 32% of Kaiser's equity
interest is publicly held.
 
     On February 1, 1993, Kaiser Aluminum & Chemical Corporation ("KACC"), the
operating subsidiary of the Company, issued $400.0 of 12 3/4% Senior
Subordinated Notes due 2003 (the "12 3/4% Notes"). The net proceeds from the
sale of the 12 3/4% Notes were used to refinance KACC's 14 1/4% Senior
Subordinated Notes due 1995 (the "14 1/4% Notes"), to prepay $18.0 of the term
loan under KACC's 1989 Credit Agreement (the "Credit Agreement"), and to reduce
outstanding borrowings under the revolving credit facility of the Credit
Agreement. These transactions resulted in a pre-tax extraordinary loss of $33.0
in the first quarter of 1993 ($21.8 after taxes), consisting primarily of the
write-off of unamortized discount and deferred financing costs related to the
14 1/4% Notes and the payment of premiums on the 14 1/4% Notes. The obligations
of KACC with respect to the 12 3/4% Notes are guaranteed, jointly and severally,
by certain subsidiaries of KACC. The Credit Agreement and the indenture in
respect of the 12 3/4% Notes (see Note 3 below) restrict, among other things,
the Company's and KACC's ability to pay dividends. Under the most restrictive of
these covenants, neither the Company nor KACC is currently permitted to pay
dividends on its common stock.
 
     On June 30, 1993, Kaiser consummated the public offering (the "Public
Offering") of 17,250,000 of its $.65 Depositary Shares (the "Depositary
Shares"), each representing one-tenth of a share of Series A Mandatory
Conversion Premium Dividend Preferred Stock (the "Series A Shares"). In
connection with the Public Offering, MAXXAM Group Inc. ("MGI"), a wholly owned
subsidiary of MAXXAM, exchanged a promissory note of KACC (the "MAXXAM Note") in
the principal amount of $15.0 (which evidenced a cash loan in the amount of
$15.0 made by MGI to KACC) for 2,132,950 Depositary Shares.
 
     The net cash proceeds from the Public Offering were approximately $119.3.
Kaiser used approximately $37.8 of such net proceeds to make a non-interest
bearing loan to KACC evidenced by a note, which note is designated to provide
sufficient funds to Kaiser to enable it to make dividend payments on the Series
A Shares until the Mandatory Conversion Date with respect to the Series A
Shares; and Kaiser used approximately $81.5 of such net proceeds and the MAXXAM
Note to make a capital contribution to KACC. KACC used approximately $13.7 of
the funds it received from Kaiser to prepay the remaining balance of the term
loan under the Credit Agreement and $105.6 of such funds to reduce outstanding
borrowings under the revolving credit facility of the Credit Agreement.
 
     At September 30, 1993, 28,000,000 shares of the Company's common stock
owned by MAXXAM were pledged as security of two new MGI debt issues, consisting
of $100.0 of 11 1/4% Senior Secured Notes due 2003, initially priced at 100%,
and $126.7 of 12 1/4% Senior Secured Discount Notes due 2003, initially priced
at 55.24%, of their principal amount.
 
     KACC announced in October that it is restructuring its flat-rolled products
operation at its Trentwood plant in Spokane, Washington, to reduce that
facility's annual operating costs. This effort is in response to over-capacity
in the aluminum rolling industry, flat demand in can stock markets, and
declining demand for

aluminum products sold to customers in the commercial aerospace industry, all of
which have resulted in declining prices in Trentwood's key markets. The Company
expects that the Trentwood restructuring, and the restructuring of operations at
some other facilities which is under consideration, are likely to result in a
fourth quarter pre-tax charge of approximately $30.0 to $40.0.

election from time to time, equal to (i) the Reference Rate plus a margin of
1 1/2%, (ii) the CD Rate (Reserve Adjusted) plus a margin of 2 5/8%, or (iii)
the LIBO Rate (Reserve Adjusted) plus a margin of 2 1/2%. All margins and fees
are subject to a reduction or increase of  1/2% per annum on a non-cumulative
basis, depending upon a financial test, determined quarterly. This financial
test required an increase in margins and fees commencing with the second quarter
of 1993, and the increase will continue at least through the fourth quarter of
1993.
 
     As of September 30, 1993, $148.9 of borrowing capacity was unused under the
revolving credit facility of the Credit Agreement (of which $13.9 could also
have been used for letters of credit).

4. EARNINGS PER COMMON SHARE
 
     Earnings per share are computed based on the weighted average number of
common and common equivalent shares outstanding during each period. For the nine
months ended September 30, 1993, common stock equivalents of 19,382,950
attributable to the Series A Shares were excluded from the calculation of
weighted average shares because they were antidilutive. Dividends on the Series
A Shares ($3.2 for the nine months ended September 30, 1993) are deducted from
net income (added to net loss) for the purpose of calculating earnings per
share.
 
5. INCOME TAXES
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes ("SFAS 109"). The
adoption of SFAS 109 changes the Company's method of accounting for income taxes
to an asset and liability approach from the deferral method prescribed by
Accounting Principles Board Opinion No. 11, Accounting for Income Taxes. The
asset and liability approach requires the recognition of deferred income tax
assets and liabilities for the expected future tax consequences of events that
have been recognized in the Company's financial statements or tax returns. Under
this method, deferred income tax assets and liabilities are determined based on
the temporary differences between the financial statement and tax bases of
assets and liabilities using enacted tax rates. The cumulative effect of the
change in accounting principle, as of January 1, 1993, reduced the Company's
results of operations by $2.3.
 
     The implementation of SFAS 109 required the Company to restate certain
assets and liabilities to their pre-tax amounts from their net-of-tax amounts
originally recorded in connection with the acquisition by MAXXAM in October
1988. The restatement of the assigned values with respect to certain assets and
liabilities recorded as a result of the acquisition and the recomputation of
deferred income tax liabilities under SFAS 109 resulted in: (i) an increase of
$144.6 in the net carrying value of property, plant, and equipment, (ii) an
increase of $47.8 in investments in and advances to unconsolidated affiliates,
(iii) an increase of $56.0 in long-term liabilities, (iv) a decrease of $2.5 in
other assets and an increase of $10.1 in other liabilities, and (v) an increase
of $126.1 in deferred income tax liabilities.
 
     Concurrent with the adoption of SFAS 109, the Company implemented changes
in its accounting methods for postretirement benefits pursuant to Statement of
Financial Accounting Standards No. 106, Employers' Accounting for Postretirement
Benefits Other Than Pensions ("SFAS 106") (see Note 6) and Statement of
Financial Accounting Standards No. 112, Employers' Accounting for Postemployment
Benefits ("SFAS 112") (see Note 7). The cumulative effect of changes in
accounting principles relating to SFAS 106 and SFAS 112 totaled approximately
$742.7 and resulted in the recognition of deferred income tax assets of $237.7,
net of valuation allowances. The Company believes that its ability to generate
future taxable income will allow for the realization of these deferred income
tax assets.

SFAS 106, and SFAS 112, the components of the Company's net deferred income tax
assets (liabilities) were as follows:

</TABLE>

 
     Certain of the deferred income tax assets and liabilities listed above are
included on the Consolidated Balance Sheet in the captions entitled Receivables,
Prepaid expenses and other current assets, Other accrued liabilities, and
Long-term liabilities. The Omnibus Budget Reconciliation Act of 1993 ("the
Act"), enacted on August 10, 1993, retroactively increased the federal statutory
income tax rate from 34% to 35% for periods beginning on or after January 1,
1993. As a result of the Act, the Company increased its net deferred income tax
assets by $3.4 and recorded a deferred tax benefit of $3.4 as of the date of the
enactment. The Company has recorded the cumulative effect of the change in the
federal statutory income tax rate as an adjustment to its credit for income
taxes in the third quarter of 1993.
 
     Current tax benefits comprise approximately $17.0 of the credit for income
taxes for the nine months ended September 30, 1993. The reconciliation of the
Company's credit (provision) for income taxes on income (loss) before income
taxes, minority interests, extraordinary loss and cumulative effect of changes
in accounting principles to the statutory rate does not differ materially from
the reconciliation disclosed in Note 5 to the audited Consolidated Financial
Statements contained in the Company's 1992 Annual Report to Stockholders.
 
     As shown in the unaudited Statement of Consolidated Income (Loss) for the
nine months ended September 30, 1993, the Company reported an extraordinary loss
related to the early extinguishment of debt. The Company reported the loss net
of related income taxes of $11.2 which approximated the statutory rate in effect
on the date the transaction occurred.. The related income tax benefits recorded
by the Company in respect of SFAS 106 and SFAS 112 differed from the statutory
rate in effect when adopted due to valuation allowances.
 
     As a consequence of the consummation of the Public Offering on June 30,
1993, as discussed in Note 1, the Company and its subsidiaries are no longer
included in the consolidated federal income tax return of MAXXAM. The Company
and its subsidiaries have become members of a new consolidated return group of

which the Company is the common parent corporation (the "New Kaiser Tax Group").
The New Kaiser Tax Group will file a consolidated federal income tax return for
taxable periods beginning on or after July 1, 1993. The Company has obtained the
approval of the Secretary of the Treasury to file a consolidated federal income
tax return for the period ending on December 31, 1993.
 
     The tax allocation agreement between the Company and MAXXAM (the "Company
Tax Allocation Agreement") terminated pursuant to its terms, effective for
taxable periods beginning after June 30, 1993. Any unused federal income tax
attribute carryforwards under the terms of the Company Tax Allocation Agreement
were eliminated and are not available for taxable periods beginning on or after
July 1, 1993. Upon the filing of MAXXAM's 1993 consolidated federal income tax
return, the tax attribute carryforwards of the MAXXAM consolidated return group
as of December 31, 1993, will be apportioned in part to the New Kaiser Tax
Group, based upon the provisions of the relevant consolidated return
regulations. It is anticipated that the amounts of such tax attribute
carryforwards apportioned to the New Kaiser Tax Group will approximate or exceed
the amounts of tax attribute carryforwards eliminated under the Company Tax
Allocation Agreement.
 
6.  POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
     The Company adopted SFAS 106 as of January 1, 1993. The costs of
postretirement benefits other than pensions are now accrued over the period
employees provide services to the date of their full eligibility for such
benefits. Previously, such costs were expensed as actual claims were incurred.
The cumulative effect of the change in accounting principle for the adoption of
SFAS 106 was recorded as a charge to results of operations of $497.7, net of
related income taxes of $234.2.
 
     The Company's accumulated postretirement benefits obligation at the date of
adoption was:

            Retirees....................................................  $581.5
            Actives eligible for benefits...............................    32.7
            Actives not eligible for benefits...........................   117.7
                                                                          ------
                                                                          $731.9
                                                                          ------
                                                                          ------
</TABLE>

 
     The annual assumed rate of increase in the per capita cost of covered
benefits (i.e., health care cost trend rate) is 9.5% for 1993 and is assumed to
decrease gradually to 6% for 2005 and remain at that level thereafter. Each one
percentage point change in the assumed health care cost trend rate would change
the accumulated postretirement benefit obligation as of January 1, 1993, by
approximately $85.0 and the aggregate of the service and interest cost
components of net periodic postretirement benefit cost for 1993 by approximately
$10.0.
 
7.  POSTEMPLOYMENT BENEFITS
 
     The Company adopted SFAS 112 as of January 1, 1993. The costs of
postemployment benefits are now accrued over the period the employee provides
services to the date of their full eligibility for such benefits. Previously,
such costs were expensed as actual claims were incurred. The cumulative effect
of the change in accounting principle for the adoption of SFAS 112 was recorded
as a charge to results of operations of $7.3, net of related income taxes of
$3.5.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Reference is made to Section 102(b)(7) of the Delaware General Corporation
Law (the "DGCL"), which enables a corporation in its original certificate of
incorporation or an amendment thereto to eliminate or limit the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of the director's fiduciary duty, except (i) for any breach
of the director's duty of loyalty to the corporation or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL
(providing for liability of directors for unlawful payment of dividends or
unlawful stock purchases or redemptions), or (iv) for any transaction from which
the director derived an improper personal benefit. The Registrant's Restated
Certificate of Incorporation contains provisions permitted by Section 102(b)(7)
of the DGCL.
 
     Reference also is made to Section 145 of the DGCL which provides that a
corporation may indemnify any person, including officers and directors, who is,
or is threatened to be made, a party to any threatened, pending or completed
legal action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of such corporation), by
reason of the fact that such person is or was an officer, director, employee or
agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation or
enterprise. The indemnity may include expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, if such
person acted in good faith and in a manner he reasonably believed to be in or
not opposed to the corporation's best interests and, with respect to any
criminal proceeding, had no reasonable cause to believe that his conduct was
unlawful. A Delaware corporation may indemnify its officers, directors,
employees and agents in an action by or in the right of the corporation under
the same conditions, except that no indemnification is permitted without
judicial approval if the officer, director, employee or agent is adjudged to be
liable to the corporation. Where an officer, director, employee or agent is
successful on the merits or otherwise in the defense of any action referred to
above, the corporation must indemnify him against the expenses which such
officer, director, employee or agent actually and reasonably incurred in
connection therewith.
 
     The restated certificate of incorporation and by-laws of the Registrant
provide for indemnification of directors, officers and employees of the
Registrant to the fullest extent authorized by law.
 
                                      II-1

<PAGE>   121
 
     The Registrant has entered into, or will enter into, indemnification
agreements with each of its directors and officers which provide that the
Registrant will indemnify such individuals if and whenever they were or are a
party or are threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that they are or were a director, officer
or employee of the Registrant or any of its subsidiaries, or are or were serving
at the request of the Registrant or any of its subsidiaries as a director,
officer, employee, agent or other official of another corporation, partnership,
joint venture, trust, or other enterprise, against judgments, fines and amounts
paid in settlement and reasonable expenses (including attorneys' fees) actually
incurred by them in connection with such action, suit or proceeding except to
the extent that (a) any judgments, fines, amounts paid in settlement and
expenses are finally determined by a court of competent jurisdiction to have
resulted from their gross negligence or bad faith in the performance of their
duties (or, alternatively in the case of certain of the indemnification
agreements, result from conduct which is finally determined by a court of
competent jurisdiction to be knowingly fraudulent or deliberately dishonest, or
to constitute willful misconduct), (b) any amount is paid without the prior
approval of the Registrant in settlement of a proceeding brought in the name and
on behalf of the Registrant or another corporation, partnership, joint venture,
trust or other enterprise for which they are or were serving at the request of
the Registrant as a director, officer, employee, agent or other official, (c)
such indemnification is otherwise prohibited by law, whether by statute, court
decision or otherwise, or (d) reimbursement of such expenses has actually been
made pursuant to insurance policies maintained by the Registrant for their
benefit. For these purposes, service at the request of the Registrant with
respect to an "other enterprise" includes service with respect to any employee
benefit plan. The agreements further provide for the advancement of expenses
incurred in defending any such action, suit or proceeding upon receipt of a
repayment undertaking if it is ultimately determined that such individuals are
not entitled to be indemnified or to the extent they recover such expenses from
others pursuant to insurance or otherwise.
 
     The Registrant may terminate the agreements on 90 days' prior written
notice to such individuals, but the indemnification provided by the agreements
continues to apply to all actions taken or failed to be taken by such

such termination.
 
     The Registrant provides liability insurance for each of its directors and
officers for certain losses arising from claims or charges made against them
while acting in their capacities as directors or officers of the Registrant.
 
     The Purchase Agreement pursuant to which securities may be purchased by
Underwriters, if any, will be expected to provide that such Underwriters will
indemnify the Company, its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Company against
certain losses related to written information furnished by such Underwriters to
the Company for inclusion in the Registration Statement or Prospectus.
 
     The foregoing discussion is qualified in its entirety by reference to the
DGCL, the Registrant's restated certificate of incorporation and by-laws, and
the referenced indemnification agreements.

ITEM 17. UNDERTAKINGS
 
     1. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions described in Item 15 above,
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
   
     2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at the time
shall be deemed to be the initial bona fide offering thereof.
    
 
   
     3. The registrant hereby undertakes:
    
 
          (1) That for purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.
 
          (2) That for the purpose of determining any liability under the Act,
     each post-effective amendment that contains a form of prospectus shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
     We have audited, in accordance with generally accepted auditing standards,
the financial statements included in the registration statement and have issued
our report thereon dated February 8, 1993. Our audit was made for the purpose of
forming an opinion on the basic financial statements taken as a whole. The
schedules listed in the index above are the responsibility of the Company's
management and are presented for purposes of complying with the Securities and
Exchange Commission's rules and are not part of the basic financial statements.
These schedules have been subjected to the auditing procedures applied in the
audit of the basic financial statements and, in our opinion, fairly state in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                 A.       Section 1.1 of the Credit Agreement is hereby amended

         from the Parent Guarantor to the Company in an aggregate principal
         amount of all or a portion of the Subsequent Net Proceeds of Equity,
         which loans shall be evidenced by, and shall be governed by the terms
         of, the Second Equity Proceeds Note."

         "Second Equity Proceeds Note' means one or more Senior Subordinated
         Intercompany Notes of the Company, in substantially the form of
         Exhibit A to the Twelfth Amendment, in an aggregate principal amount
         not to exceed an amount equal to 50% of the Subsequent Net Proceeds of
         Equity.  If the preferred stock issued in the Second 1993 Equity
         Offering is convertible into shares of the Parent Guarantor's common
         stock, the Second Equity Proceeds Note shall provide that immediately
         upon the conversion of all of the shares of preferred stock (or
         depositary shares in respect thereof) of the Parent Guarantor issued
         in the Second 1993 Equity Offering into shares of the common stock of
         the Parent Guarantor pursuant to the Certificate of Designations
         governing such shares of preferred stock (or the Depositary Agreement
         in respect of such depositary shares), the Company may, after the
         payment of all amounts payable by the Parent Guarantor in respect of
         accrued and unpaid dividends in connection with all such conversions,
         defer further principal and interest payments on the Second Equity
         Proceeds Note until such time as no Senior Indebtedness of the Company
         (as defined in the Second Equity Proceeds Note) is then outstanding)."

         "Second Equity Proceeds Purchase' means (i) a capital contribution
         from the Parent Guarantor to the Company in an amount equal to all or
         a portion of the Subsequent Net Proceeds of Equity, or (ii) a purchase
         by the Parent Guarantor from the Company of shares of capital stock of
         the Company for an aggregate consideration equal to all or a portion
         of the Subsequent Net Proceeds of Equity."

         sale of equity securities of the Parent Guarantor pursuant to or in

         Guarantor or the Company."

         all underwriting discounts and commissions and all legal, accounting
         and other fees and expenses incurred in connection with the Second
         1993 Equity Offering."

         "Twelfth Amendment' means the Twelfth Amendment to Credit Agreement
         dated as of December 20, 1993 among the Company, the Parent Guarantor,

amended to read in its entirety as follows:

                 "SECTION 10.2.23.  Equity Proceeds Loan and Second Equity
Proceeds Loan.  The Company will not, without the written consent of the
Required Banks,

                 (a)      consent to any amendment, supplement, or other
modification of any of the terms or provisions contained in the Equity Proceeds
Note or the Second Equity Proceeds Note, other than any amendment, supplement,
or other modification consented to in writing by the Agent;

                 (b)      make any payment or prepayment of principal of, or of
interest on, the Equity Proceeds Note or the Second Equity Proceeds Note except
that the Company may pay principal and interest from time to time on the Equity
Proceeds Note and/or the Second Equity Proceeds Note in accordance with the
provisions of





                                       6

<PAGE>   7
the Equity Proceeds Note or the Second Equity Proceeds Note, as the case may
be, subject to the terms of Section 7 thereof; provided, however, that
immediately upon any conversion of the shares of preferred stock (or depositary
shares in respect thereof) of the Parent Guarantor issued in the 1993 Equity
Offering into shares of the common stock of the Parent Guarantor pursuant to
the Certificate of Designations governing such shares of preferred stock (or
the Depositary Agreement in respect of such depositary shares), the Company
shall, after the payment of all amounts payable by the Parent Guarantor in
respect of accrued and unpaid dividends in connection with such conversion and
in accordance with the terms of the Equity Proceeds Note, defer further
principal and interest payments on the Equity Proceeds Note until such time as
no Senior Indebtedness of the Company (as defined in the Equity Proceeds Note)
is then outstanding and provided, further, that if the preferred stock issued
in the Second 1993 Equity Offering is convertible into shares of the Parent
Guarantor's common stock, the Second Equity Proceeds Note shall provide that
immediately upon the conversion of all of the shares of preferred stock (or
depositary shares in respect thereof) of the Parent Guarantor issued in the
Second 1993 Equity Offering into shares of the common stock of the Parent
Guarantor pursuant to the Certificate of Designations governing such shares of
preferred stock (or the Depositary Agreement in respect of such depositary
shares), the Company shall, after the payment of all amounts payable by the
Parent Guarantor in respect of accrued and unpaid dividends in connection with
all such conversions and in accordance with the terms of the Second Equity
Proceeds Note, defer further principal and interest payments on the Second
Equity Proceeds Note until such time as no Senior Indebtedness of the Company
(as defined in the Second Equity Proceeds Note) is then outstanding); or

                 (c)      redeem, purchase or defease the Equity Proceeds Note
or the Second Equity Proceeds Note.

Upon any conversion of the shares of preferred stock (or depositary shares in
respect thereof) of the Parent Guarantor issued in the 1993 Equity Offering
into shares of the common stock of the Parent Guarantor pursuant to the
Certificate of Designations governing such shares of preferred stock (or the
Depositary Agreement in respect of such depositary shares), the Parent
Guarantor shall, after all amounts payable by the Parent Guarantor in respect
of accrued and unpaid dividends in connection with such conversion have been
paid, if requested by the Agent, with the consent of the Required Banks,
deliver the Equity Proceeds Note to the Company as a capital contribution and
the Company shall immediately cancel the Equity Proceeds Note.  If the
preferred stock issued in the Second 1993 Equity Offering is convertible into
shares of the Parent Guarantor's common stock, and if, following any conversion
of any shares of such preferred stock (or depositary shares in respect thereof)
into shares of the common stock of the Parent Guarantor pursuant to





                                       7

<PAGE>   8
the Certificate of Designations governing such shares of preferred stock (or
the Depositary Agreement in respect of such depositary shares), the next
scheduled quarterly payment under the Second Equity Proceeds Note shall exceed
by more than $5000 the product (such product being herein called the "Fixed
Quarterly Dividend Requirement") of (x) the number of shares of preferred stock
issued in the Second 1993 Equity Offering (or depositary shares in respect
thereof) then outstanding and (y) the then quarterly dividend rate for such
shares of preferred stock (or depositary shares in respect thereof), the Parent
Guarantor shall, after all amounts payable by the Parent Guarantor in respect
of accrued and unpaid dividends in connection with any such conversion have
been paid, if requested by the Agent, with the consent of the Required Banks,
contribute to the capital of the Company a portion of the Second Equity
Proceeds Note such that each level quarterly payment of principal and interest
on the remaining outstanding principal amount of the Second Equity Proceeds
Note shall not exceed by more the $50 the Fixed Quarterly Dividend Requirement.
Anything in this Agreement to the contrary notwithstanding, any modification to
the Second Equity Proceeds Note required for compliance with the preceding
sentence shall not be deemed to violate any provision of this Agreement or of
any other Loan Document.  In addition, the Parent Guarantor will not, without
the written consent of the Required Banks, consent to any amendment, supplement
or other modification of any of the terms or provisions contained in, or
applicable to, any document or instrument evidencing or governing the preferred
stock (or depositary shares in respect thereof) issued by the Parent Guarantor
in the 1993 Equity Offering or the Second 1993 Equity Offering if such
amendment, supplement or other modification would have a Materially Adverse
Effect."

                 SECTION 2.  AMENDMENTS TO KT PLEDGE AGREEMENT AND KT SECURITY
AGREEMENT.

                 The parties agree that, as of the Twelfth Amendment Effective
Date (as defined below), the KT Pledge Agreement and the KT Security Agreement
shall be amended as set forth in Exhibits B and C hereto.

                 SECTION 3.  LIMITED WAIVER

                 The undersigned Banks, constituting the Required Banks under
the Credit Agreement, hereby waive compliance with the provisions of Section

to excuse the Company's failure to provide at least five Business Days prior

in a loan to the Government of Jamaica.

                 A.       AUTHORIZATION OF AGREEMENTS.  The execution and
delivery of this Amendment by the Company and the Parent Guarantor and the
performance of the Credit Agreement as amended by this Amendment (the "Amended
Agreement") by the Company and the Parent Guarantor are within such Obligor's
corporate powers and have been duly authorized by all necessary corporate
action on the part of the Company and the Parent Guarantor, as the case may be.

                 B.       NO CONFLICT.  The execution and delivery by the
Company and the Parent Guarantor of this Amendment and the performance by the
Company and the Parent Guarantor of the Amended Agreement do not:

                 (a)      contravene such Obligor's Organic Documents;

                 (b)      contravene any contractual restriction where such a
         contravention has a reasonable possibility of having a Materially

         its Subsidiaries; or

         Documents.

                 C.       BINDING OBLIGATION.  This Amendment has been duly
executed and delivered by the Company and the Parent Guarantor and this
Amendment and the Amended Agreement constitute the legal, valid and binding
obligations of the Company and the Parent Guarantor, enforceable against the
Company and the Parent Guarantor in accordance with their respective terms,
except as may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to or limiting creditors' rights generally and by
general principles of equity.

         shall be limited precisely as written and relates solely to the
         noncompliance by the Company with the provision ofSection 10.1.8 of
         the Credit Agreement in the manner and to the extent described above,
         and nothing herein shall be deemed to (a) constitute a waiver of
         compliance by the Company with respect to (1)Section 10.1.8 of the
         Credit Agreement in any other instance or (2) any other term,
         provision or condition of the Credit Agreement or any other instrument

interpretation of this Amendment or any provision hereof.

                 D.       COUNTERPARTS.  This Amendment may be executed by the
parties hereto in several counterparts and by the different parties on separate
counterparts, each of which shall be deemed to be an original and all of which
shall constitute together but one and the same instrument; signature pages may

counterpart so that all signature pages are physically attached to the same
document.

                 E.       SEVERABILITY.  Any provision of this Amendment which
is prohibited or unenforceable in any jurisdiction shall, as to such provision
and such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions of this

         waiver of any provision of, or operate as a waiver of any right, power
         or remedy of the Agent, the Collateral Agent or any Bank under, the
         Credit Agreement or any of the other Loan Documents.

                 The opinions set forth in paragraphs 3 and 6 above are subject
to the following qualifications and limitations (and the other opinions set
forth above are subject to the following qualifications and limitations, other
than those set forth in clauses (a), (b) and (c) below):

                 (a)      The enforceability of the Twelfth Amendment, the KT
Pledge Agreement Amendment and the KT Security Agreement Amendment may be
subject to or limited by bankruptcy, insolvency, reorganization, arrangement,
fraudulent conveyance or transfer, moratorium, or other laws and court
decisions, now or hereafter in effect, relating to or affecting the rights of

                 (b)      The enforceability of the Twelfth Amendment, the KT
Pledge Agreement Amendment and the KT Security Agreement Amendment is subject
to the application of and may be limited by general principles of equity,
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing (regardless of whether considered in a proceeding in
equity or at

law).  Such principles of equity are of general application and in applying
such principles a court, among other things, might not allow a creditor to
accelerate maturity of a debt under certain circumstances, including, without
limitation, upon the occurrence of a default deemed immaterial or might decline
to order an obligor to perform covenants.  Such principles applied by a court
might include a requirement that a creditor act with reasonableness and in good
faith.  Thus, we express no opinion as to the validity or enforceability of (i)
provisions restricting access to legal or equitable remedies, such as the
specific performance of executory covenants, (ii) provisions that purport to
establish evidentiary standards, (iii) provisions relating to waivers,
severability, indemnity, submissions to jurisdiction, set off, delay or
omission of enforcement of rights or remedies, and (iv) provisions purporting
to convey rights to persons other than parties to the Credit Agreement.  In
addition, we express no opinion as to the enforceability of any provision
purporting to provide indemnification or contribution relating to matters
arising under Federal or State securities laws;

                 (c)      The remedy of specific performance and injunctive and
other forms of equitable relief are subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought;
and

                 (d)      Our opinion expressed herein is limited to the laws
of the State of New York, the General Corporation Law of the State of Delaware,
and the Federal laws of the United States of America, and we do not express any
opinion herein concerning any other laws.  We express no opinion as to the
effects (if any) of any laws of any jurisdiction (except the State of New York)
in which any Bank is located which limits the rate of interest that such Bank
may charge or collect.

                 The opinion expressed herein is based upon the laws in effect
on the date hereof, and we assume no obligation to review or supplement this
opinion should any such law be changed by legislative action, judicial decision
or otherwise.

         Adverse Effect, or contravene any law or governmental regulation or

         any of its Subsidiaries; or

                 (c)      result in, or require the creation or imposition of,

         Documents.

                 C.       BINDING OBLIGATION.  This Amendment has been duly
executed and delivered by the Parent Guarantor and this Amendment and the
Amended Agreement constitute the legal, valid and binding obligations of the
Parent Guarantor, enforceable against the Parent Guarantor in accordance with
their respective terms, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to or limiting creditors'
rights generally and by general principles of equity.

                 D.       GOVERNMENTAL APPROVAL, REGULATION, ETC.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or other Person is required for
the due execution, delivery or performance of this Amendment by the Parent
Guarantor.

                 SECTION 4.  MISCELLANEOUS.

                 A.       REFERENCE TO AND EFFECT ON THE KT PLEDGE AGREEMENT

                 (i)      On and after the Second Amendment Effective Date,
         each reference in the KT Pledge Agreement to "this Agreement",
         "hereunder", "hereof", "herein" or words of like import referring to
         the KT Pledge Agreement, and each reference in the other Loan
         Documents to the "KT Pledge Agreement", "thereunder", "thereof" or
         words of like import referring to the KT Pledge Agreement shall mean
         and be a reference to the Amended Agreement.

<PAGE>   40
                 (ii)   Except as specifically amended by this Amendment, the
         KT Pledge Agreement and the other Loan Documents shall remain in full
         force and effect and are hereby ratified and confirmed.

                 (iii)  The execution, delivery and performance of this
         Amendment shall not, except as expressly provided herein, constitute a
         waiver of any provision of, or operate as a waiver of any right, power
         or remedy of the Agent, the Collateral Agent or any Bank under, the
         Credit Agreement or any of the other Loan Documents.

                 B.     APPLICABLE LAW.  THIS AMENDMENT SHALL BE DEEMED TO BE
A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW
YORK, WITHOUT GIVING EFFECT TO SUCH LAWS RELATING TO CONFLICTS OF LAWS.

                 C.     HEADINGS.  The various headings of this Amendment are
inserted for convenience only and shall not affect the meaning or
interpretation of this Amendment or any provision hereof.

                 D.     COUNTERPARTS.  This Amendment may be executed by the
parties hereto in several counterparts and by the different parties on separate
counterparts, each of which shall be deemed to be an original and all of which
shall constitute together but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

                 E.     SEVERABILITY.  Any provision of this Amendment which
is prohibited or unenforceable in any jurisdiction shall, as to such provision
and such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions of this
Amendment or affecting the validity or enforceability of such provisions in any
other jurisdiction.

                 SECTION 3.  PARENT GUARANTOR'S REPRESENTATIONS AND WARRANTIES.

                 In order to induce the Collateral Agent to enter into this
Amendment and to amend the KT Security Agreement in the manner provided herein,
the Parent Guarantor represents and warrants to each Bank, the Agent and the
Collateral Agent that, as of the Second Amendment Effective Date after giving
effect to the effectiveness of this Amendment, the following statements are
true and correct in all material respects:

                 A.       AUTHORIZATION OF AGREEMENTS.   The execution and
delivery of this Amendment by the Parent Guarantor and the performance of the
KT Security Agreement as amended by this Amendment (the "Amended Agreement") by
the Parent Guarantor are within its corporate powers and have been duly
authorized by all necessary corporate action on the part of the Parent
Guarantor.

                 B.       NO CONFLICT.  The execution and delivery by the
Parent Guarantor of this Amendment and the performance by the Parent Guarantor
of the Amended Agreement do not:

                 (a)      contravene its Organic Documents;

                 (b)      contravene any contractual restriction where such a
         contravention has a reasonable possibility of having a Materially
         Adverse Effect, or contravene any law or governmental regulation or
         court decree or order binding on or affecting the Parent Guarantor or
         any of its Subsidiaries; or

                 (c)      result in, or require the creation or imposition of,
         any Lien on any of the Parent Guarantor's properties or any of the
         properties of any its Subsidiaries, other than pursuant to the Loan
         Documents.

                 C.       BINDING OBLIGATION.  This Amendment has been duly
executed and delivered by the Parent Guarantor and this Amendment and the
Amended Agreement constitute the legal, valid and binding obligations of the
Parent Guarantor, enforceable against the Parent Guarantor in accordance with
their respective terms, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to or limiting creditors'
rights generally and by general principles of equity.

                 D.       GOVERNMENTAL APPROVAL, REGULATION, ETC.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or other Person is required for
the due execution, delivery or performance of this Amendment by the Parent
Guarantor.

                 SECTION 4.  MISCELLANEOUS.

                 A.       REFERENCE TO AND EFFECT ON THE KT SECURITY AGREEMENT
AND THE OTHER LOAN DOCUMENTS.

                          (i)    On and after the Second Amendment Effective
         Date, each reference in the KT Security Agreement to "this Agreement",
         "hereunder", "hereof", "herein" or words of like import referring to
         the KT Security Agreement, and each reference in the other Loan
         Documents to the "KT Security Agreement", "thereunder", "thereof" or
         words of like import referring to the KT Security Agreement shall mean
         and be a reference to the Amended Agreement.

                          (ii)   Except as specifically amended by this
         Amendment, the KT Security Agreement and the other Loan Documents
         shall remain in full force and effect and are hereby ratified and
         confirmed.

                          (iii)  The execution, delivery and performance of
         this Amendment shall not, except as expressly provided herein,
         constitute a waiver of any provision of, or operate as a waiver of any
         right, power or remedy of the Agent, the Collateral Agent or any Bank
         under, the Credit Agreement or any of the other Loan Documents.

                 B.       APPLICABLE LAW.  THIS AMENDMENT SHALL BE DEEMED TO BE
A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW
YORK, WITHOUT GIVING EFFECT TO SUCH LAWS RELATING TO CONFLICTS OF LAWS.

                 C.       HEADINGS.  The various headings of this Amendment are
inserted for convenience only and shall not affect the meaning or
interpretation of this Amendment or any provision hereof.

                 D.       COUNTERPARTS.   This Amendment may be executed by the
parties hereto in several counterparts and by the different parties on separate
counterparts, each of which shall be deemed to be an original and all of which
shall constitute together but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

                 E.        SEVERABILITY.   Any provision of this Amendment
which is prohibited or unenforceable in any jurisdiction shall, as to such
provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
of this Amendment or affecting the validity or enforceability of such
provisions in any other jurisdiction.

Ladies and Gentlemen:
 
   
     We refer to the registration statement on Form S-3 (Reg. No. 33-51391), as
amended (the "Registration Statement"), filed by Kaiser Aluminum Corporation, a
Delaware corporation (the "Company"), with the Securities and Exchange
Commission (the "Commission") relating to the offer and sale by the Company of
Preferred Redeemable Increased Dividend Equity Securities,      % PRIDES,
Convertible Preferred Stock, par value of $.05 per share (the "PRIDES"). Unless
otherwise specifically provided herein, capitalized terms used herein shall have
the meanings ascribed to them in the Registration Statement.
    
 
     In the connection with the foregoing, we have examined originals,
photocopies or conformed copies of all such corporate records, agreements,
instruments and documents of the Company, certificates of public officials and
other certificates and opinions, and have made such other investigations as we
have deemed necessary for the purpose of rendering the opinion set forth herein.
We have relied, without independent investigation or verification, upon

statements and representations of representatives of the Company, certificates
of officers of the Company and certificates of public officials. In our
examination, we have assumed the genuineness of all signatures, the authenticity
of all documents submitted to us as originals, the conformity to the originals
of all copies submitted to us as conformed copies or photocopies, and the
authenticity of the originals of such latter documents.
 
     Based upon and subject to the foregoing, we are of the opinion that (i)
upon designation of the preferences and relative, participating, optional and
other special rights, qualifications, limitations or restrictions and other
terms of the PRIDES by the Board of Directors of the Company or by a duly
authorized committee thereof, and upon the filing with the Secretary of State of
the State of Delaware of a Certificate of Designations relating to the PRIDES
(the "Certificate of Designations"), the PRIDES, when issued, sold and delivered
in the manner contemplated by the Registration Statement, will be validly
issued, fully paid and non-assessable and (ii) the Common Stock issuable upon
conversion or redemption of the PRIDES referred to in clause (i), when issued
and delivered upon such conversion or redemption in the manner provided in the
Certificate of Designations, will be validly issued, fully paid and
non-assessable.
 
     We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the heading "Legal
Matters" in the prospectus that forms a part thereof. In giving this consent, we
do not thereby admit that we are within the category of persons whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Commission thereunder.
 
     Ezra G. Levin, a director of the Company, Kaiser Aluminum & Chemical
Corporation, MAXXAM Group Inc., and MAXXAM Inc., and a trustee of Federated
Development Company, is a member of our firm.
 
     We are delivering this opinion to the Company, and no person other than the
Company may rely upon it.
 
                                          Very truly yours,
 
                                          /s/  Kramer, Levin, Naftalis, Nessen,
                                                 Kamin & Frankel
