the Indenture.  It is also provided in the Indenture that the
holders of a majority of the aggregate principal amount of the

outstanding or outstanding on the record date, if any, fixed

evidenced as in the Indenture provided, to execute supplemental
indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of

    Any such consent or waiver by the registered holder of this

shall be conclusive and binding upon such holder and upon all
future holders of this Note and of any Note issued in exchange or
substitution herefor, irrespective of whether or not any notation
of such consent or waiver is made upon this Note or such other
Note.

Note at the place, at the respective times, at the rate and in
the currency herein prescribed.

    The Notes are issuable as fully registered Notes without

$1,000.  At the office or agency to be maintained by the Company
referred to on the face hereof, and in the manner and subject to
the limitations provided in the Indenture, Notes may be exchanged

in each case together with accrued and unpaid interest to (but
not including) the date fixed for redemption.

    Subject to the terms and conditions of the Indenture, if any
Change of Control (as defined in the Indenture) occurs on or
prior to maturity, the Company shall offer to purchase from each
holder all or any part of the holder's Notes for which a Change
of Control Purchase Notice shall have been delivered as provided
in the Indenture and not withdrawn, on the date that is 30
Business Days after the occurrence of such Change of Control (the
"Change of Control Purchase Date"), for a Change of Control
Purchase Price equal to 101% of the principal amount thereof plus
accrued interest to (but not including) the Change of Control
Purchase Date, which Change of Control Purchase Price shall be
paid in cash.

    Holders have the right to withdraw any Change of Control
Purchase Notice by delivering to the Trustee a written notice of
withdrawal in accordance with the provisions of the Indenture.

    If cash sufficient to pay the Change of Control Purchase
Price of all Notes or portions thereof to be purchased on the
Change of Control Purchase Date is deposited with the Trustee as
of the Change of Control Purchase Date, interest shall cease to
accrue (whether or not this Note is delivered to the Trustee or
any other office or agency maintained for such purpose) on such
Notes (or portions thereof) on and after the Change of Control
Purchase Date, and the holders thereof shall have no other rights
as such (other than the right to receive the Change of Control
Purchase Price, upon surrender of such Notes).

    Subject to the terms and conditions of the Indenture, the
Company shall apply the Net Cash Proceeds (as defined in the
Indenture) of Asset Sales (as defined in the Indenture), under
certain circumstances described in the Indenture, to (x) the
prepayment of Indebtedness (as defined in the Indenture) in
respect of or under the Credit Agreement (as defined in the
Indenture) and the Specified Pari Passu Indebtedness (as defined
in the Indenture) unless the holders thereof elect not to receive
such prepayment and (y) an offer to purchase (an "Asset Sale
Offer") the then outstanding Notes, on any Business Day occurring
no later than 175 days after the receipt by the Company (or any
of its Subsidiaries, if applicable) of such Net Cash Proceeds, at
a price equal to 100% of the principal amount thereof together
with accrued interest, if any, to but not including the Asset
Sale Purchase Date (as defined in the Indenture).  Such Asset
Sale Offer with respect to the Notes shall be in an aggregate
principal amount (the "Asset Sale Offer Amount") equal to the Net
Cash Proceeds (rounded down to the nearest $1,000) from the Asset
Sales to which the Asset Sale Offer relates multiplied by a
fraction, the numerator of which is the principal amount of the
Notes outstanding (determined as of the close of business on the
day immediately preceding the date notice of such Asset Sale
Offer is mailed) and the denominator of which is the principal
amount of the Notes outstanding plus the aggregate principal
amount of Indebtedness under the Credit Agreement and the
Specified Pari Passu Indebtedness outstanding (determined as of
the close of business on the day immediately preceding the date
notice of such Asset Sale Offer is mailed).  If (x) no
Indebtedness is outstanding in respect of or under the Credit
Agreement or the Specified Pari Passu Indebtedness or (y) the
holders of such Indebtedness entitled to 

                                     5

receive payment elect not to receive the payments provided for in
the previous sentence, or (z) the application of such Net Cash
Proceeds results in the complete prepayment of such Indebtedness,
then in each case any remaining portion of such Net Cash Proceeds
will be required to be applied to an Asset Sale Offer to purchase
the Notes.

    Upon surrender of this Note, the transfer of this Note is
registrable by the registered holder hereof in person or by his
attorney duly authorized in writing on the registry books of the
Company at the office or agency to be maintained by the Company
referred to on the face hereof, subject to the terms of the
Indenture but without payment of any charge other than a sum
sufficient to reimburse the Company for any tax or other
governmental charge incident thereto.  Upon any such registration
of transfer, a new Note or Notes of authorized denomination or
denominations, for the same aggregate principal amount, will be
issued to the transferee in exchange herefor.

    Prior to due presentation for registration of transfer, the
Company, the Trustee, any paying agent and any Note registrar may
deem and treat the person in whose name this Note shall be
registered upon the registry books of the Company as the absolute
owner of this Note (whether or not this Note shall be overdue and
notwithstanding any notation of ownership or other writing
hereon), for the purpose of receiving payment of or on account of
the principal hereof, premium, if any, Change of Control Purchase
Price, Asset Sale Purchase Price and interest due hereon and for
all other purposes, and neither the Company nor the Trustee nor
any paying agent nor any Note registrar shall be affected by any
notice to the contrary.  All such payments shall be valid and
effectual to satisfy and discharge the liability on this Note to
the extent of the sum or sums so paid.

    No recourse shall be had for the payment of the principal
of, premium, if any, Change of Control Purchase Price, Asset Sale
Purchase Price or the interest on this Note, or for any claim
based hereon, or otherwise in respect hereof, or based on or in
respect of the Indenture or any indenture supplemental thereto,
against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Company or of any successor
corporation, whether by virtue of any constitution, statute or
rule of law, or by the enforcement of any assessment or penalty
or otherwise, all such liability being, by the acceptance hereof
and as part of the consideration for the issue hereof, expressly
waived and released.

                                ARTICLE TWO

                ISSUE, DESCRIPTION, EXECUTION, REGISTRATION
                           AND EXCHANGE OF NOTES

    SECTION 2.01.  Designation, amount, authentication and 
                    ----------------------------------------
delivery of Notes.  The Notes shall be designated as the 
- -----------------
Company's 9 % Senior Notes due 2002.  Notes for an aggregate
principal amount of two hundred twenty five million dollars
($225,000,000), upon the execution of this Indenture, or from
time to time thereafter, may be executed by the Company and
delivered to the Trustee for authentication, and the Trustee
shall thereupon authenticate and deliver said Notes to or upon
the written order of the Company, signed by its Chairman of the
Board, President or a Vice President, without any further
corporate action by the Company.

    The aggregate principal amount of Notes authorized by this
Indenture is limited to two hundred twenty five million dollars
($225,000,000), and, except as provided in this Section 2.01 and
in Section 2.07, the Company shall not execute and the Trustee
shall not authenticate or deliver Notes in excess of such
aggregate principal amount.

    Nothing contained in this Section 2.01 or elsewhere in this
Indenture, or in the Notes, is intended to or shall limit
execution by the Company or authentication or delivery by the
Trustee of Notes under the circumstances contemplated by Sections
2.05, 2.06, 2.07, 3.03, 3.05 and 10.04.

    SECTION 2.02.  Form of Notes and Trustee's certificate.  The 
                    ----------------------------------------
definitive Notes and the Trustee's certificate of authentication
to be borne by the Notes shall be substantially in the form set
forth in the Recitals of this Indenture, which are part of this
Indenture, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements
printed, lithographed or engraved thereon as the officers
executing the same may deem appropriate and as are not
inconsistent with the provisions of this Indenture, or as may be
required to comply with any law or with any rule or regulation
made pursuant thereto or with any rule or regulation of any stock
exchange on which the Notes may be listed, or to conform to
usage.

    SECTION 2.03.  Date of Notes and denominations.  The Notes 
                    --------------------------------
shall bear interest at the rate per annum of 9 %, payable semi-
annually on February 15 and August 15, shall mature on
February 15, 2002 and shall be issuable as registered Notes
without coupons in denominations of $1,000 and any integral
multiple thereof.  The person in whose name any Note is
registered at the close of business on any record date (as
hereinbelow defined) with respect to any interest payment date
shall be entitled to receive the interest payable thereon on such
interest payment date notwithstanding the cancellation of such
Note upon any registration of transfer or exchange thereof
subsequent to such record date and prior to such interest payment
date, unless such Note shall have been redeemed on a date fixed
for redemption subsequent to such record date and prior to such
interest payment date, or unless an Event of Default shall have
occurred and be continuing as the result of a default in the
payment of interest due on such interest payment date on any
Note, in which case such defaulted interest shall be paid to the
person in whose name such Note (or any Note or Notes issued upon
registration of transfer or exchange thereof) is registered on
the record date for the payment of such defaulted interest.  The
principal of, premium, if any, Change of Control Purchase Price,
Asset Sale Purchase Price and interest on the Notes shall be
payable at the office or agency to be maintained by the Company
in accordance with the provisions of Section 4.02; provided,
however, that payment of interest may be made at the option of
the Company by check mailed by first-class mail to the address of
the person entitled thereto as such address shall appear on the
registry books of the Company.  The term "record date" as used in
this Section 2.03 with respect to any interest payment date shall
mean the close of business on the February 1 or August 1, as 

                                    31

 40

the case may be, next preceding such interest payment date,
whether or not such February 1 or August 1 is a Business Day, and
such term, as used in this Section 2.03, with respect to the
payment of any defaulted interest shall mean the tenth day next
preceding the date fixed by the Company for the payment of
defaulted interest whether or not a Business Day, but in no case
shall such record date be less than ten days after notice thereof
shall have been mailed by or on behalf of the Company to all
registered holders of Notes at their addresses.

    The Notes shall be dated the date of their authentication. 
Except as provided in the next sentence, interest shall accrue on
the Notes from the most recent date to which interest has been
paid or duly provided for or, if no interest has been paid or
duly provided for, from February 17, 1994.  Each Note
authenticated between the record date for any interest payment
date and such interest payment date shall be dated the date of
its authentication but shall bear interest from such interest
payment date; provided, however, that if and to the extent the
Company shall default in the payment of the interest due on such
interest payment date, then any Note so authenticated shall bear
interest from the February 15 or August 15, as the case may be,
next preceding the date of such Note to which interest has been
paid or duly provided for or, if no interest has been paid or
duly provided for on the Notes, from February 17, 1994.

    Interest on the Notes shall be computed on the basis of a
360-day year comprised of twelve 30-day months.

    SECTION 2.04.  Execution of Notes.  The Notes shall be 
                    -------------------
signed on behalf of the Company, manually or in facsimile, by its
Chairman of the Board or its President or a Vice President under
its corporate seal (which may be in facsimile) reproduced thereon
and attested, manually or in facsimile, by its Secretary or an
Assistant Secretary.  Only such Notes as shall bear thereon a
certificate of authentication substantially in the form
hereinbefore recited, signed manually by the Trustee, shall be
entitled to the benefits of this Indenture or be valid or
obligatory for any purpose.  Such signature by the Trustee upon
any Note executed by the Company shall be conclusive evidence
that the Note so authenticated has been duly authenticated and
delivered hereunder and that the holder is entitled to the
benefits of this Indenture.

    In case any officer of the Company whose signature appears
on any of the Notes, manually or in facsimile, shall cease to be
such officer before such Notes so signed shall have been
authenticated and delivered by the Trustee, such Notes
nevertheless may be authenticated and delivered as though the
person whose signature appears on such Notes had not ceased to be
such officer of the Company; and any Note may be signed, and the
corporate seal reproduced thereon may be attested, on behalf of
the Company, manually or in facsimile, by persons as, at the
actual date of the execution of such Note, shall be the proper
officers of the Company, although at the date of the execution of
this Indenture any such person was not such officer.

    SECTION 2.05.  Exchange and transfer of Notes.  Notes may be 
                    -------------------------------
exchanged for a like aggregate principal amount of Notes in other
authorized denominations.  Notes to be exchanged shall be
surrendered at the office or agency to be maintained by the
Company in accordance with the provisions of Section 4.02, and
the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor the Note or Notes which the
noteholder making the exchange shall be entitled to receive.

    The Company shall keep, at the office or agency to be
maintained by the Company in accordance with the provisions of
Section 4.02, a register or registers in which, subject to such
reasonable regulations as it may prescribe, the Company shall
register Notes and shall register the transfer of Notes as in
this Article Two provided.  Upon surrender for registration of
transfer of any Note at such office or agency,

                                    32

 41

the Company shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new Note
or Notes for a like aggregate principal amount.

    All Notes presented or surrendered for exchange,
registration of transfer, redemption, purchase or payment shall,
if so required by the Company or the Trustee or any Note
registrar (if other than the Trustee), be accompanied by a
written instrument or instruments of transfer, in form
satisfactory to the Company and the Trustee or the Note registrar
(if other than the Trustee), duly executed by the registered
holder or by his attorney duly authorized in writing and, in
every case, each Note presented or surrendered for registration
of transfer shall be accompanied by the assignment form attached
to the Notes, duly executed by the registered holder or by his
attorney duly authorized in writing.

    No service charge shall be made for any exchange or
registration of transfer of Notes, but the Company may require
payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto.

    The Company shall not be required to issue, register the
transfer of or exchange any Notes for a period of fifteen days
next preceding any date for the selection of Notes to be
redeemed.  The Company shall not be required to register the
transfer of or exchange any Note called or being called for
redemption except, in the case of any Note to be redeemed in
part, the portion thereof not to be so redeemed.  The Company
shall not be required to register the transfer of or exchange any
Note in respect of which a Change of Control Purchase Notice or
an Asset Sale Purchase Notice has been given (unless such notice
has been withdrawn in accordance with Section 3.06 or 4.14)
except, in the case of any Note to be purchased in part, the
portion thereof not to be so purchased.

    SECTION 2.06.  Temporary Notes.  Pending the preparation of 
                    ----------------
definitive Notes, the Company may execute and the Trustee shall
authenticate and deliver temporary Notes (printed, lithographed
or typewritten) of any authorized denomination and substantially
in the form of the definitive Notes, but with or without a
recital of specific redemption prices and with such omissions,
insertions and variations as may be appropriate for temporary
Notes, all as may be determined by the Company.  Temporary Notes
may contain such reference to any provisions of the Indenture as
may be appropriate.  Every temporary Note shall be authenticated
by the Trustee upon the same conditions and in substantially the
same manner, and with the same effect, as the definitive Notes. 
Without unnecessary delay the Company will execute and deliver to
the Trustee definitive Notes and thereupon any or all temporary
Notes may be surrendered in exchange therefor, at the office or
agency to be maintained by the Company in accordance with the
provisions of Section 4.02, and the Trustee shall authenticate
and deliver in exchange for such temporary Notes an equal
aggregate principal amount of definitive Notes.  Until so
exchanged, the temporary Notes shall in all respects be entitled
to the same benefits under this Indenture, and shall be subject
to the same provisions hereof, as definitive Notes authenticated
and delivered hereunder.

    SECTION 2.07.  Mutilated, destroyed, lost or stolen Notes.  
                    -------------------------------------------
In case any temporary or definitive Note shall become mutilated
or be destroyed, lost or stolen, the Company, in the case of any
mutilated Note shall, and in the case of any destroyed, lost or
stolen Note may, execute, and upon its request the Trustee shall
authenticate and deliver, a new Note bearing a number, letter or
other distinguishing symbol not contemporaneously outstanding in
exchange and substitution for the mutilated Note, or in lieu of
and in substitution for the Note so destroyed, lost or stolen,
or, instead of issuing a substituted Note, if any such Note shall
have matured or shall be about to mature or shall have been
selected for redemption or if the Company shall have received a
Change of Control Purchase Notice or an Asset Sale Purchase
Notice in respect of any such Note (unless such notice has been
withdrawn in accordance with Section 3.06 or 4.14), the Company
may pay the same without surrender thereof except in the case of
a mutilated Note.  In every case the applicant for a substituted
Note or for such payment shall furnish to the 

                                    33

 42

Company and to the Trustee such security or indemnity as may be
required by them to save each of them harmless, and, in every
case of destruction, loss or theft, the applicant shall also
furnish to the Company and to the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Note and
of the ownership thereof.  The Trustee may authenticate any such
substituted Note and deliver the same, or the Trustee or any
paying agent of the Company may make any such payment, upon the
written request or authorization of any officer of the Company. 
Upon the issuance of any substituted Note, the Company may
require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and
any other expenses connected therewith.

    Every substituted Note issued pursuant to the provisions of
this Section 2.07 shall constitute an additional contractual
obligation of the Company whether or not the destroyed, lost or
stolen Note shall be found at any time, and shall be entitled to
all the benefits of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder.

    All Notes shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen
Notes, and shall preclude (to the extent lawful) any and all
other rights or remedies, notwithstanding any law or statute
existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other
securities without their surrender.

    SECTION 2.08.  Cancellation of surrendered Notes.  All Notes 
                    ----------------------------------
surrendered for the purpose of payment, redemption, purchase by
the Company at the option of the holder, exchange, substitution
or registration of transfer, shall, if surrendered to the Company
or any paying agent or Note registrar, be delivered to the
Trustee and the same, together with Notes surrendered to the
Trustee for cancellation, shall be cancelled by it, and no Notes
shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Indenture.  The Trustee shall
destroy cancelled Notes and shall deliver certificates of
destruction thereof to the Company.  If the Company shall
purchase or otherwise acquire any of the Notes, however, such
purchase or acquisition shall not operate as a payment,
redemption or satisfaction of the indebtedness represented by
such Notes unless and until the Company, at its option, shall
deliver or surrender the same to the Trustee for cancellation.


                               ARTICLE THREE

                     REDEMPTION AND PURCHASES OF NOTES

    SECTION 3.01.  Redemption prices.  The Company may, at its 
                    ------------------                    
option, redeem at any time all or from time to time any part of
the Notes, on any date prior to maturity at the redemption prices
specified in the Notes, together with accrued and unpaid interest
thereon to but excluding the date fixed for redemption and in the
manner set forth in this Article Three.  The Company, however,
shall not have the right to redeem any of the Notes prior to
February 15, 1998.

    SECTION 3.02.  Notice of redemption; selection of Notes.  In 
                    -----------------------------------------
case the Company shall desire to exercise such right to redeem
all or, as the case may be, any part of the Notes in accordance
with the right reserved so to do, the Company, or, at the
Company's request, the Trustee in the name and at the expense of
the Company, shall fix a date for redemption and give notice of
such redemption to holders of the Notes to be redeemed as
hereinafter in this Section 3.02 provided.

    Notice of redemption shall be given to the holders of Notes
to be redeemed as a whole or in part by mailing by first-class
mail a notice of such redemption not less than fifteen nor more
than sixty days

                                    34

 43

prior to the date fixed for redemption to their last addresses as
they shall appear upon the registry books of the Company, but any
failure to give such notice by mailing to the holder of any Note
designated for redemption as a whole or in part, or any defect
therein, shall not affect the validity of the proceedings for the
redemption of any other Notes.

    Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether
or not the holder receives the notice.

    Each such notice of redemption shall specify the total
principal amount to be redeemed, the date fixed for redemption
and the redemption price at which Notes are to be redeemed, and
shall state that payment of the redemption price of the Notes to
be redeemed will be made at the office or agency to be maintained
by the Company in accordance with the provisions of Section 4.02,
upon presentation and surrender of such Notes, that interest
accrued to but not including the date fixed for redemption will
be paid as specified in said notice, and that on and after said
date interest thereon will cease to accrue and that the only
remaining right of the noteholder is to receive payment of the
redemption price plus such accrued interest upon surrender.  If
less than all the Notes are to be redeemed, the notice of
redemption to each holder also shall state the aggregate
principal amount of Notes to be redeemed and shall identify the
Notes of such holder to be redeemed.  In case any Note is
redeemed in part only, the notice which relates to such Note
shall state the portion of the principal amount thereof to be
redeemed (which shall be $1,000 or an integral multiple thereof),
and shall state that on and after the date fixed for redemption,
upon surrender of such Note, the holder will receive, without
charge, a new Note or Notes of authorized denominations in the
principal amount thereof remaining unredeemed.  Each notice shall
give the name and address of each paying agent.

    On or prior to the date fixed for redemption specified in
the notice of redemption given as provided in this Section 3.02,
the Company will deposit with the Trustee or with one or more
paying agents (or, if the Company is acting as its own paying
agent, set aside, segregate and hold in trust as provided in
Section 4.04(c)) an amount of money sufficient to redeem on the
date fixed for redemption all the Notes or portions of Notes so
called for redemption (other than Notes or portions thereof
called for redemption on that date which have been delivered by
the Company to the Trustee for cancellation) at the applicable
redemption price, together with accrued interest to but not
including the date fixed for redemption.  

    If less than all the Notes then outstanding are to be
redeemed, the Company shall give the Trustee, at least
twenty-five days (or such shorter period acceptable to the
Trustee) in advance of the date fixed for redemption, notice of
the aggregate principal amount of Notes to be redeemed, and
thereupon the Trustee shall select in such manner as it shall
deem appropriate and fair, in its discretion, the Notes or
portions thereof to be redeemed and shall thereafter promptly
notify the Company of the Notes or portions thereof to be
redeemed within a sufficient period of time in order that the
notice provision in Section 3.02 may be satisfied.

    SECTION 3.03.  When Notes called for redemption become due 
                    --------------------------------------------
and payable.  If the giving of notice of redemption shall have 
- -----------
been completed as provided in Section 3.02, the Notes or portions
of Notes specified in such notice shall become due and payable on
the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to (but not
including) the date fixed for redemption, and on and after such
date fixed for redemption (unless the Company shall default in
the payment of such Notes at the redemption price, together with
interest accrued to (but not including) the date fixed for
redemption) interest on the Notes or portions of Notes so called
for redemption shall cease to accrue whether or not such Notes
are presented for payment and such Notes or portions thereof
shall be deemed not to be outstanding hereunder and shall not be
entitled to any right or benefit hereunder

                                    35

 44

except to receive payment of the redemption price plus accrued
interest to but not including the redemption date.  On
presentation and surrender of such Notes for redemption at said
place of payment in said notice specified on or after the date
fixed for redemption, the said Notes shall be paid and redeemed
by the Company at the applicable redemption price, together with
interest accrued to (but not including) the date fixed for
redemption.  If the date fixed for redemption is an interest
payment date, such payment shall not include accrued interest,
which interest shall be paid in the usual manner otherwise
provided for herein.  Upon presentation of any Note which is
redeemed in part only, the Company shall execute and register and
the Trustee shall authenticate and deliver to the holder thereof
at the expense of the Company, a new Note or Notes in principal
amount equal to the unredeemed portion of the Note so presented.

    SECTION 3.04.  Cancellation of redeemed Notes.  All Notes 
                    -------------------------------
surrendered to the Trustee, upon redemption pursuant to the
provisions of this Article Three, shall be forthwith cancelled by
it.

    SECTION 3.05.  Purchase of Notes at option of the holder 
                    ------------------------------------------
upon Change of Control.
- ----------------------

    (a)  If on or prior to maturity, there shall have occurred a
Change of Control, the Company shall offer to purchase each Note
at a purchase price in cash equal to 101% of the principal amount
thereof plus interest accrued to (but not including) the Change
of Control Purchase Date (the "Change of Control Purchase
Price"), on the date that is thirty Business Days after the
occurrence of the Change of Control (the "Change of Control
Purchase Date"), subject to the satisfaction by or on behalf of
the holder of the requirements set forth in Section 3.05(c). 
Following a Change of Control, the Company shall not be obligated
to purchase any Notes pursuant to this Section 3.05(a) or give
any notice under Section 3.05(b) with respect to any subsequent
Change of Control.  The Company's obligation to purchase Notes as
provided hereunder shall for all purposes hereof be satisfied by,
and shall cease upon, the deposit of funds with the Trustee as
provided for in Section 3.07.

    A "Change of Control" shall be deemed to have occurred at
such time as MAXXAM, directly or indirectly, shall cease to have
(other than by reason of the existence of a Lien but including by
reason of the foreclosure of or other realization upon a Lien)
direct or indirect sole beneficial ownership (as defined under
Regulation 13d-3 of the Exchange Act as in effect on the date of
this Indenture) of at least 40% of the total Voting Stock, on a
fully diluted basis, of the Company; provided, however, that such
ownership by MAXXAM, directly or indirectly, of 30% or greater,
but less than 40%, of the total Voting Stock, on a fully diluted
basis, of the Company shall not be a Change of Control if MAXXAM,
through direct representation or through persons nominated by it,
controls a majority of the Board of Directors of the Company
necessary to effectuate any actions by the Board of Directors of
the Company; and provided, further, that the foregoing minimum
percentages shall be deemed not satisfied if any person or group
(as defined in Section 13(d)(3) of the Exchange Act as in effect
on the date of this Indenture) shall, directly or indirectly, own
more of the total Voting Stock entitled to vote generally in the
election of directors of the Company than MAXXAM.

    "Voting Stock" means, with respect to any person, the
capital stock of such person having general voting power under
ordinary circumstances to elect at least a majority of the board
of directors, managers or trustees of such person (irrespective
of whether or not at the time capital stock of any other class or
classes shall have or might have voting power by reason of the
happening of any contingency).

    (b)  Within ten Business Days after the occurrence of a
Change of Control, the Company shall mail a written notice of
Change of Control by first-class mail to the Trustee and to each
holder (and to beneficial owners as required by applicable law,
including without limitation, Rule 13e-4 of the Exchange Act, if
applicable) and shall cause a copy of such notice to be published
in a daily newspaper of national

                                    36

 45

circulation.  The notice shall include a form of Change of
Control Purchase Notice (as described below) to be completed by
the holder and shall state:

    SECTION 3.06.  Effect of Change of Control Purchase Notice.  
                    --------------------------------------------
Upon receipt by the Company of the Change of Control Purchase
Notice specified in Section 3.05(c), the holder of the Note in
respect of which such Change of Control Purchase Notice was given
shall (unless such Change of Control Purchase Notice is withdrawn
as specified in the following paragraph) thereafter be entitled
to receive solely the Change of Control Purchase Price with
respect to such Note.  Such Change of Control Purchase Price
shall be due and payable as of the Change of Control Purchase
Date and shall be paid to such holder promptly following the
later of (x) the Change of Control Purchase Date (provided the
conditions in Section 3.05(c), as applicable, have been
satisfied) and (y) the date of delivery of such Note to the
Trustee or to the office or agency referred to in Section 4.02 by
the holder thereof in the manner required by Section 3.05(c). 

    A Change of Control Purchase Notice may be withdrawn by
means of a written notice of withdrawal delivered to the office

    (1)  the certificate number or numbers of the Note or Notes
in respect of which such notice of withdrawal is being submitted;

    (2)  the principal amount of the Note or Notes with respect

    (3)  the principal amount, if any, of such Note or Notes
which remains subject to the original Change of Control Purchase
Notice, and which has been or will be delivered for purchase by
the Company.

    There shall be no purchase of any Notes pursuant to Section
3.05 if there has occurred (prior to, on or after, as the case
may be, the giving, by the holders of such Notes, of the required
Change of

                                    38

 47

Control Purchase Notice), and is continuing an Event of Default
(other than a default in the payment of the Change of Control
Purchase Price with respect to such Notes).

    SECTION 3.07.  Deposit of Change of Control Purchase Price.  
                    --------------------------------------------
On or prior to the Change of Control Purchase Date, the Company
shall deposit with the Trustee (or, if the Company or a
Subsidiary or an Affiliate of either of them is acting as paying
agent, shall segregate and hold in trust as provided in Section
4.04(c)) an amount of cash in immediately available funds
sufficient to pay the aggregate Change of Control Purchase Price
of all the Notes or portions thereof which are to be purchased on
the Change of Control Purchase Date.  Upon such deposit, the
Company shall be deemed to have satisfied its obligations to
purchase Notes pursuant to Section 3.05.  If cash sufficient to
pay the Change of Control Purchase Price of all Notes or portions
thereof to be purchased on the Change of Control Purchase Date is
deposited with the Trustee as of the Change of Control Purchase
Date, interest shall cease to accrue (whether or not any such
Note is delivered to the Trustee or any other office or agency
maintained for such purpose) on such Notes (or portions thereof)
on and after the Change of Control Purchase Date, and the holders
thereof shall have no other rights as such (other than the right
to receive the Change of Control Purchase Price, upon surrender
of such Notes).

    SECTION 3.08.  Covenant to comply with securities laws upon 
                    ---------------------------------------------
purchase of Notes.  In connection with any offer to purchase or 
- ------------------
any purchase of securities under Section 3.05 hereof, the Company
shall (i) comply with Section 14(e) under the Exchange Act (or
any successor provision thereof), if applicable, and (ii)
otherwise comply with all Federal and state securities laws
regulating the purchase of the Notes so as to permit the rights
and obligations under Section 4.05 to be exercised in the time
and in the manner specified in Sections 4.05 and 4.06.

    SECTION 3.09.  Repayment to the Company.  The Trustee shall 
                    -------------------------
return to the Company any cash, together with interest or
dividends, if any, thereon (subject to the provisions of Section
7.05) held by it for the payment of the Change of Control
Purchase Price of the Notes that remain unclaimed as provided in
Section 12.04 hereof; provided, however, that to the extent that
the aggregate amount of cash deposited by the Company pursuant to
Section 3.07 exceeds the aggregate Change of Control Purchase
Price of the Notes or portions thereof to be purchased on the
Change of Control Purchase Date, then promptly after the Change
of Control Purchase Date, the Trustee shall return any such
excess to the Company together with interest or dividends, if
any, thereon (subject to the provisions of Section 7.05).

Price and interest on each of the Notes at the time and place
such amounts may become due and payable and in the manner
provided in the Notes and this Indenture.

    SECTION 4.02.  Maintenance of office or agency for

                                    39

and where the Notes may be presented or surrendered for payment,
redemption or purchase.  The Company may also from time to time

                                                 --------
however, that no such designation or rescission shall in any 
- -------
manner relieve the Company of its obligation to maintain an
office or agency in the Borough of Manhattan, City of New York,
State of New York for such purposes.  The Company will give to

    agent for the payment of the principal of, premium, if any,

Trustee.

    (b)  If the Company shall not act as its own paying agent,
it will, prior to each due date of the principal of, premium, if
any, Change of Control Purchase Price, Asset Sale Purchase Price
or interest on any Notes, deposit with such paying agent a sum
sufficient to pay the principal, premium, if any, Change of
Control Purchase Price, Asset Sale Purchase Price or interest so
becoming due, such sum to be held in trust for the benefit of the
holders of Notes entitled to such principal, premium, if any,
Change of Control Purchase Price, Asset Sale Purchase Price or
interest, and (unless such paying agent is the Trustee) the
Company will promptly notify the Trustee of its failure so to
act.

    (c)  If the Company shall act as its own paying agent, it
will, on or before each due date of the principal of, premium, if
any, Change of Control Purchase Price, Asset Sale Purchase Price

done all things necessary to preserve and keep in full force and
effect its corporate existence and the corporate existence of
each Subsidiary; provided, however, that nothing herein shall 
                 --------  -------
require the Company to continue the corporate existence of any
Subsidiary other than a Subsidiary Guarantor (so long as any such
Subsidiary is a Subsidiary Guarantor) if in the judgment of the
Company it shall be necessary, advisable or in the interest of
the Company to discontinue the same; and provided, further, that 
                                         --------  -------

         (1)  a review of the activities of the Company during
    such year and of performance under this Indenture has been
    made under his supervision, and

         (2)  to the best of his knowledge, based on such
    review, there is no Event of Default or event which with
    notice or the passage of time would become an Event of
    Default which has occurred and is continuing, or, if there
    is such an event or Event of Default, specifying each such
    event or Event of Default known to him and the nature and

Affiliate of the Company, unless:

         (i)  the terms thereof are no less favorable to the

         (ii)  such transaction or series of related
    transactions shall have been approved as meeting such
    standard, in good faith, by a majority of the independent

    (or, if the aggregate Consolidated Net Income of the Company
    for any such period shall be a deficit, minus 100% of such
    deficit) accrued on a cumulative basis for the period (taken
    as one accounting period) from January 1, 1993 to the end of

respect to the Notes to the same extent as such subordinated
Indebtedness is subordinated to the Notes or such Subsidiary
Guarantor's obligation under its Guarantee, as the case may be;
and provided, further, that this paragraph shall not be 
    --------  -------
applicable to any assumption, guarantee or other liability of any
Subsidiary of the Company which existed at the time such Person
became a Subsidiary of the Company and was not Incurred in
connection with, or in contemplation of, such Person becoming a
Subsidiary of the Company, or any Refinancing Indebtedness in
connection therewith complying with Section 4.10(b)(vi)
(provided, that the guarantee of such Refinancing Indebtedness is 
 --------
on substantially the same terms as the guarantee of the
Refinanced Indebtedness).  In the event that any Subsidiary of
the Company (other than a Subsidiary Guarantor) is required to
guarantee the Notes pursuant to the next preceding sentence, the
Company shall cause such Subsidiary to (a) execute and deliver to
the Trustee a supplemental indenture in form and substance
reasonably satisfactory to the Trustee pursuant to which such
Subsidiary shall be named as an additional Subsidiary Guarantor
for so long as such Subsidiary Guarantor is so obligated with
respect to such Other Indebtedness and (b) deliver to the Trustee
an Opinion of Counsel reasonably satisfactory to the Trustee that
such supplemental indenture has been duly executed and delivered
by such Person.

    (d)  For the purpose of determining compliance with this
Section 4.10, in the event that any Indebtedness is permitted to
be Incurred pursuant to more than one clause of Section 4.10(b),
the Incurrence of such Indebtedness shall not limit the amount of
Indebtedness otherwise permitted to be Incurred, and shall not be
required to be included, under more than one such clause.

    SECTION 4.11.  Limitation on Liens.
                    --------------------

         (a)  The Company shall not, and shall not permit any of
its Subsidiaries to, create, incur, assume or suffer to exist any
Lien upon any of their respective U.S. Fixed Assets to secure,
directly or indirectly, any Indebtedness, unless the Notes are
equally and ratably secured on a senior basis for so long as such
secured Indebtedness is so secured.

         (b)  Notwithstanding anything to the contrary, this
Section 4.11 shall not prohibit:

         (i)  Liens on the Permitted Collateral securing
    outstanding Indebtedness permitted by this Indenture in an
    aggregate principal amount not to exceed the Maximum Secured
    Amount at the time such Indebtedness is Incurred; 

                                    50

 59

         (ii)  Liens in existence on the date of the issuance of
    the Notes after giving effect thereto which Liens, if such
    Liens secure a single or related items of Indebtedness in a
    principal amount in excess of $5,000,000, are referred to in
    Schedule A hereto;

         (iii)  Liens in favor of the Company or any Subsidiary
    Guarantor;

         (iv)  Liens on U.S. Fixed Assets of a person existing
    at the time such person is merged into or consolidated with
    the Company or any Subsidiary of the Company, provided, that 
                                                  --------
     such Liens were in existence prior to the contemplation of
     such merger or consolidation and do not extend to any other
     U.S. Fixed Assets of the Company or any Subsidiary of the
     Company; 
     
         (v)  Liens on U.S. Fixed Assets existing at the time of
    acquisition thereof by the Company or any Subsidiary of the
    Company, provided, that such Liens were in existence prior 
              ---------
     to the contemplation of such acquisition and do not extend
     to any other U.S. Fixed Assets of the Company or any
     Subsidiary of the Company;
     
         (vi)  Liens securing Indebtedness permitted by clauses
    (vii), (viii) and (ix) of Section 4.10(b), provided, that 
                                                ---------
     such Liens do not extend to any U.S. Fixed Assets other than
     the Center for Technology in the case of clause (vii), the
     applicable aluminum smelter or smelters and related
     facilities in the case of clause (viii) and the applicable
     fabrication plant or plants and related facilities in the
     case of clause (ix), and, in each case, together with any
     Improvements thereto or thereon and any proceeds thereof;
     
         (vii)  Liens securing Indebtedness permitted by clause
    (e) of the definition of Permitted Indebtedness;

         (viii)  Liens securing the Indebtedness permitted by
    clauses (iii), (iv) or (v) of Section 4.10(b) provided that 
                                                   ---------
     such Liens do not extend to any U.S. Fixed Assets other than
     (a) Permitted Collateral (in which case the principal amount
     of such Indebtedness shall be included in the calculation of
     the Maximum Secured Amount for purposes of clause (i) of
     this paragraph and such Liens shall only be permitted if the
     requirements of clause (i) are satisfied) and (b) the
     Capital Stock and assets of Alpart, KJC and AJI in the case
     of clause (iii), the Capital Stock and assets of KAAC in the
     case of clause (iv), and the Capital Stock and assets of
     VALCO in the case of clause (v), plus, in each case, the
     proceeds thereof;
     
         (ix)  Liens securing Indebtedness consisting of
    Capitalized Lease Obligations, mortgage financings,
    industrial revenue bonds or other monetary obligations, in
    each case incurred for the purpose of financing all or any
    part of the purchase price or cost of construction or
    installation of U.S. Fixed Assets used in the business of
    the Company and its Subsidiaries, or repairs, additions or
    Improvements to such U.S. Fixed Assets, provided, that such 
                                             ---------
     Liens (a) secure Indebtedness in an amount not in excess of
     the original purchase price or the original cost of any such
     U.S. Fixed Assets or repair, addition or Improvement thereto
     (plus an amount equal to the reasonable fees and expenses in
     connection with the Incurrence of such Indebtedness), (b) do
     not extend to any other U.S. Fixed Assets (other than
     Improvements thereto or thereon and any proceeds thereof) of
     the Company or any Subsidiary of the Company (and, in the
     case of a repair, addition or Improvement, such Lien extends
     only to the U.S. Fixed Assets (and Improvements thereto or
     thereon) repaired, added to or improved), and (c) secure
     Indebtedness incurred no later than 180 days after the
     acquisition or final completion of such construction,
     repair, addition or Improvement;
     
                                    51

 60

         (x)  Liens securing any Refinancings (in whole or in
    part) of any Indebtedness secured by the Liens described in
    clauses (ii), (iv), (v), (vi), (viii) or (ix) of this
    paragraph, and any successive Refinancings of any thereof
    (together with any increased amount of such Indebtedness
    specifically permitted pursuant to Section 4.10(b) to cover
    the reasonable fees and expenses incurred in connection with
    a Refinancing)), provided that each such Lien (unless 
                      ---------
     otherwise permitted by this paragraph) does not extend to
     any additional U.S. Fixed Assets (other than Improvements
     thereto or thereon and any proceeds thereof); 
     
         (xi)  Liens on U.S. Fixed Assets securing Indebtedness
    in an aggregate principal amount not to exceed $10,000,000;
    and

         (xii)  Liens on any U.S. Fixed Assets consisting of
    easements, covenants, restrictions, exceptions, reservations
    and similar matters which do not materially impair the use
    of such U.S. Fixed Assets for the uses for which it is held
    and which Liens are granted to secure Indebtedness secured
    by Liens permitted by the foregoing clauses (i) through
    (xi).

         (c)  For purposes of this Section 4.11, the Notes will
be considered equally and ratably secured on a senior basis with
any other Lien if the Lien securing the Notes is of at least
equal priority and covers the same U.S. Fixed Assets as such
other Lien, provided, that if the Indebtedness secured by such 
            --------
other Lien is expressly subordinated in right and priority of
payment by its terms to the Notes, the Lien securing the Notes
will be senior to such other Lien.

         (d)  For the purpose of determining compliance with
this Section 4.11, in the event that any Lien is permitted
pursuant to more than one clause of Section 4.11(b), such Lien
shall not limit any other Lien otherwise permitted, and shall not
be required to be included under more than one such clause.

    SECTION 4.12.  Subsidiary guarantees, etc.
                    ----------------------------

    (a)  If the Company or any Subsidiary Guarantor shall
transfer or cause to be transferred, in one or a series of
related transactions, any property or assets (including, without
limitation, businesses, divisions, real property, assets or
equipment) to any Subsidiary of the Company or to any Non-
Affiliate Joint Venture of the Company, the Company shall cause
such transferee Subsidiary or Non-Affiliate Joint Venture to (i)
execute and deliver to the Trustee a supplemental indenture in
form and substance reasonably satisfactory to the Trustee
pursuant to which such transferee Subsidiary or Non-Affiliate
Joint Venture shall be named as an additional Subsidiary
Guarantor and (ii) deliver to the Trustee an Opinion of Counsel
reasonably satisfactory to the Trustee that such supplemental
indenture has been duly executed and delivered by such Person.

paragraph shall not apply to the following transfers of property
or assets by the Company or any Subsidiary Guarantor:

         (A)  transfers of property or assets (other than cash)
    to Subsidiaries of the Company and Non-Affiliate Joint 
     Ventures,  provided that such transfer is made in exchange 
                --------
     for cash in an amount equal to the Fair Market Value of such
     property or assets;
     
         (B)  transfers of property or assets to Subsidiary
    Guarantors;

         (C)  the use of the proceeds of Indebtedness described

                                    52

 61

         (D)  transfers to Alpart of the proceeds of
    Indebtedness described in Section 4.10(a) to the extent that
    Alpart is an obligor or guarantor of such Indebtedness;

         (E)  the provision of, and the payment for, goods and
    services, working capital and technology to Subsidiaries of
    the Company and Non-Affiliate Joint Ventures in each case in
    the ordinary course of the businesses in which the Company
    or its Subsidiaries or its Non-Affiliate Joint Ventures were
    engaged on the date of this Indenture or reasonably related
    extensions thereof;

         (F)  transfers of assets to a Subsidiary of the Company
    immediately prior to the sale of such Subsidiary;

    related extensions thereof;

         (H)  transfers of cash, Cash Equivalents, property or
    other assets to a Permitted Entity in exchange for Permitted
    Entity Securities of such Permitted Entity if, immediately
    after giving effect to such transfer, such Permitted Entity
    remains a Permitted Entity;

         (I)  transfers of Capital Stock or other equity
    interests to the issuer of such Capital Stock or other
    equity interests such that immediately after giving effect
    to such transfer and related transfers, the proportional
    beneficial ownership by the transferor of the class of
    Capital Stock or equity interests so transferred is not
    reduced; and

         (J)  other transfers of assets, provided that the 
                                           --------
     aggregate amount thereof (if other than cash, such amount
     shall be the Fair Market Value of such asset at the time of
     such transfer), less the aggregate amount of such assets
     returned to the Company or any Subsidiary Guarantor (if
     returned other than in cash, the amount of such assets shall
     be the Fair Market Value of such assets at the time so
     returned), does not exceed, in the aggregate, the greater of
     (i) $25,000,000 or (ii) 5% of the Company's Consolidated Net
     Worth, calculated after giving effect to such transfers and
     returns.
     
    (c)  If any of the Company's existing or future Subsidiaries
(other than a Bank Guarantor) or existing or future Non-Affiliate
Joint Ventures shall guarantee, directly or indirectly, or become
a direct obligor with respect to, Indebtedness under the Credit
Agreement or any Refinancings thereof, the Company shall cause
each such Subsidiary or Non-Affiliate Joint Venture to (A)
execute and deliver to the Trustee a supplemental indenture in
form and substance reasonably satisfactory to the Trustee
pursuant to which such Subsidiary or Non-Affiliate Joint Venture
shall be named as an additional Subsidiary Guarantor for as long
as such Subsidiary or Non-Affiliate Joint Venture is so obligated
with respect to such Indebtedness and (B) deliver to the Trustee
an Opinion of Counsel reasonably satisfactory to the Trustee that
such supplemental indenture has been duly executed and delivered
by such Person.

    (d)  Sections 4.12(a) and (b) shall not apply to any
Restricted Investment or Restricted Payment otherwise permitted
by Section 4.09.

    (e)  The Company shall not permit any Permitted Entity to
cease to be a Permitted Entity except:

         (i)  pursuant to a liquidation or dissolution of such
    Permitted Entity or a transfer of all or substantially all
    of the properties and assets of such Permitted Entity to its
    Equity Owners in

                                    53

 62

     proportion to their interests, including by way of merger or
     consolidation of such Permitted Entity with or into its sole
     Equity Owner;
     
         (ii)  pursuant to a sale in compliance with Section
    4.14 of all of the Permitted Entity Securities of such
    Permitted Entity held directly or indirectly by the Company
    or any Subsidiary Guarantor; or

         (iii)  if such Permitted Entity becomes a Subsidiary
    Guarantor.

    (f)  Notwithstanding anything in this Section 4.12 to the
contrary, VALCO shall be permitted to merge with or into, or
distribute substantially all of its assets and liabilities to, a
Permitted Entity, provided that, at the time of such merger or 
                  --------
distribution, such Permitted Entity has no more than $50,000 of
assets other than Capital Stock or other similar interests in
VALCO.  Upon the consummation of any transaction contemplated by
this clause (f), the entity surviving such merger or distribution
shall not be required (i) to become a Subsidiary Guarantor
pursuant to this Section 4.12 or (ii) if such entity has no
assets except as contemplated in this clause (f) or meets the
conditions of clause (e) of this Section 4.12, to remain a
Permitted Entity pursuant to the this Section 4.12.

    SECTION 4.13.  Limitation on dividends and other payment 
                    ------------------------------------------
restrictions affecting Subsidiaries.  The Company shall not, and
- -----------------------------------
shall not permit its Subsidiaries to, create or otherwise suffer
to exist any consensual encumbrances or restrictions on the
ability of any Subsidiary to pay dividends or make any other
distributions on its Capital Stock or pay any Indebtedness owed
to the Company or any Subsidiaries of the Company or to make
loans or advances or transfer any of its assets to the Company or
any Subsidiary of the Company; provided, however that this 
                               --------  -------
Section 4.13 shall not prohibit Permitted Dividend Encumbrances.

    SECTION 4.14.  Limitation on Asset Sales.
                    --------------------------

    (a)  The Company shall not, and shall not permit any of its
Subsidiaries to, consummate any Asset Sale unless at least 75% of
the consideration therefor received by the Company or such
Subsidiary (exclusive of indemnities) is in the form of cash or
Cash Equivalents, provided that this sentence shall not apply to 
                  --------
the sale or disposition of assets as a result of a foreclosure
(or a secured party taking ownership of such assets in lieu of
foreclosure) or as a result of an involuntary proceeding in which
the Company cannot, directly or through its Subsidiaries, direct
the type of proceeds received.  The amount of (i) any liabilities
of the Company or any Subsidiary of the Company that are actually
assumed by the transferee in such Asset Sale, or for which the
Company and its Subsidiaries are fully released, shall be deemed
to be cash for purposes of determining the percentage of cash
consideration received by the Company or its Subsidiaries and
(ii) any notes or other obligations received by the Company or
any Subsidiary of the Company from such transferee that are
immediately converted (or are converted within thirty days of the
related Asset Sale) by the Company or such Subsidiary into cash
shall be deemed to be cash for purposes of determining the
percentage of cash consideration received by the Company or its
Subsidiaries.

    (b)  The Company shall apply any Net Cash Proceeds received
after the date of this Indenture to (A) the prepayment of
Indebtedness in respect of or under the Credit Agreement and any
other Indebtedness of the Company (other than the Notes) entitled
to receive payment pursuant to the terms thereof (excluding
Indebtedness that is subordinated by its terms to the Notes or
the Guarantee thereof) (the "Specified Pari Passu Indebtedness"),
unless the holders thereof elect not to receive such prepayment
and (B) an offer to purchase (an "Asset Sale Offer") the then
outstanding Notes, on any Business Day occurring no later than
175 days after the receipt by the Company (or any of its
Subsidiaries, if 

                                    54

 63

applicable) of such Net Cash Proceeds (the "Asset Sale Purchase
Date," which date shall be deferred to the extent necessary to
permit the Asset Sale Offer to remain open for the period
required by applicable law), at a price (the "Asset Sale Purchase
Price") equal to 100% of the principal amount thereof together
with accrued interest, if any, to but not including the Asset
Sale Purchase Date pursuant to the provisions set forth below. 
Such Asset Sale Offer with respect to the Notes shall be in an
aggregate principal amount (the "Asset Sale Offer Amount") equal
to the Net Cash Proceeds (rounded down to the nearest $1,000)
from the Asset Sales to which the Asset Sale Offer relates
multiplied by a fraction, the numerator of which is the principal
amount of the Notes outstanding (determined as of the close of
business on the day immediately preceding the date notice of such
Asset Sale Offer is mailed) and the denominator of which is the
principal amount of the Notes outstanding plus the aggregate
principal amount of Indebtedness under the Credit Agreement and
the Specified Pari Passu Indebtedness outstanding (determined as
of the close of business on the day immediately preceding the
date notice of such Asset Sale Offer is mailed).  If (x) no
Indebtedness is outstanding in respect of or under the Credit
Agreement or the Specified Pari Passu Indebtedness or (y) the
holders of such Indebtedness entitled to receive payment elect
not to receive the payments provided for in the previous
sentence, or (z) the application of such Net Cash Proceeds
results in the complete prepayment of such Indebtedness, then in
each case any remaining portion of such Net Cash Proceeds will be
required to be applied to an Asset Sale Offer to purchase the
Notes. 

    (c)  Notice of an Asset Sale Offer shall be mailed by the
Company to all holders at their last registered address within
145 days of the receipt by the Company or any of its Subsidiaries
of such Net Cash Proceeds.  The Asset Sale Offer shall remain
open from the time of mailing until the last Business Day before
the Asset Sale Purchase Date, but in no event for a period less
than twenty-four days or less than that required by applicable
law.  The notice shall state:

         (1)  that the Asset Sale Offer is being made pursuant
    to this Section 4.14;

         (2)  the Asset Sale Offer Amount, the purchase price
    and the Asset Sale Purchase Date;

         (3)  the name and address of the Trustee and that Notes
    must be surrendered to the Trustee to collect the purchase
    price;

         (4)  that any Note not tendered or accepted for payment
    will continue to accrue interest;

         (5)  that any Note accepted for payment pursuant to the
    Asset Sale Offer shall cease to accrue interest on and after
    the Asset Sale Purchase Date;

         (6)  that each holder electing to have a Note purchased
    pursuant to an Asset Sale Offer will be required to
    surrender the Note, with the form entitled "Option of Holder
    to Elect Purchase" on the reverse of the Note (the "Asset
    Sale Purchase Notice") completed, to the Trustee at the
    address specified in the notice at least five Business Days
    before the Asset Sale Purchase;

         (7)  that holders will be entitled to withdraw their
    election if the Trustee receives, not later than one
    Business Day prior to the Asset Sale Purchase Date, a
    telegram, telex, facsimile transmission or letter setting
    forth the name of the holder, the principal amount of the
    Notes the holder delivered for purchase, the certificate
    number of each Note the holder delivered for purchase and a
    statement that such holder is withdrawing his, her or its
    election to have such Notes purchased;

    


                                    55

 64

         (8)  that if Notes in a principal amount in excess of
     the Asset Sale Offer Amount are surrendered pursuant to the
     Asset Sale Offer, the Company shall purchase Notes on a pro
                                                             ----
     rata basis (with such adjustments as may be deemed 
     ----
     appropriate by the Company so that only Notes in
     denominations of $1,000 or integral multiples thereof shall
     be acquired); and
     
         (9)(x) that Notes may be purchased in whole or in part
    (in denominations of $1,000 or integral multiples thereof)
    and (y) that holders whose Notes are purchased only in part
    will be issued new Notes equal in principal amount to the
    unpurchased portion of the Notes surrendered.

    On or before the Asset Sale Purchase Date, the Company shall
(i) accept for payment Notes (having denominations of $1,000 or
integral multiples thereof) surrendered pursuant to the Asset
Sale Offer (on a pro rata basis if required pursuant to paragraph 
                 --- ----
(c)(8) above), (ii) deposit by 10:30 a.m. New York City time, on
the Asset Sale Purchase Date, with the Trustee money in
immediately available funds sufficient to pay the Asset Sale
Purchase Price of all Notes or portions thereof so accepted and
(iii) deliver Notes so accepted to the Trustee together with an
Officers' Certificate stating the Notes or portions thereof
accepted for payment by the Company.  The Trustee shall promptly
mail or deliver to holders of Notes so accepted payment in an
amount equal to the purchase price, and the Company shall execute
and the Trustee shall promptly authenticate and mail or deliver
to such holders a new Note equal in principal amount to any
unpurchased portion of the Note surrendered.  Any Notes not so
accepted shall be promptly mailed or delivered to the holder
thereof.  The Company will publicly announce the results of the
Asset Sale Offer on, or as soon as practicable after, the Asset
Sale Purchase Date.

    Notwithstanding the foregoing, the Company shall not be
required to make an Asset Sale Offer until the aggregate amount
of Net Cash Proceeds so to be applied pursuant to this Section
4.14 exceeds $25,000,000 (the "Twenty-Five Million Threshold")
and then the total amount of such Net Cash Proceeds shall be
required to be so applied in accordance with this Section 4.14. 
The Company may credit against its obligation to offer to
repurchase Notes pursuant to this Section 4.14 the principal
amount of Notes acquired or held by the Company subsequent to the
date of the Asset Sale giving rise to such Asset Sale Offer and
surrendered for cancellation or redeemed or called for redemption
subsequent to such date and not previously used to satisfy any
obligation of the Company to redeem or offer to purchase Notes. 
In no event shall any Net Cash Proceeds that are applied to an
Asset Sale Offer be required to be applied to more than one Asset
Sale Offer.

    (d)  Notwithstanding the provisions of clauses (a) and (b)
of this Section 4.14, the Company shall have no obligation to
make an Asset Sale Offer pursuant to this Section 4.14 if, and to
the extent, the Company or any of its Subsidiaries commits within
140 days of the receipt of such Net Cash Proceeds to reinvest
(whether by acquisition of an existing business or expansion,
including, without limitation, capital expenditures) such Net
Cash Proceeds in one or more of the lines of business (including
capital expenditures) in which the Company or its Subsidiaries or
its Non-Affiliate Joint Ventures were engaged on the date of this
Indenture or reasonably related extensions of such lines of
business, provided that such Net Cash Proceeds are substantially 
          --------
so utilized no later than the last day of the twelfth consecutive
month (or, in the event the amount of such Net Cash Proceeds from
a single Asset Sale or series of related Asset Sales exceeds
$200,000,000, the twenty-fourth consecutive month) following the
month in which such Net Cash Proceeds are received.

    (e)  Notwithstanding the foregoing, if an Asset Sale
consists of a sale of (i) all or a portion of the property, plant
or equipment of the Company's Gramercy alumina refinery, whether
now owned or hereafter acquired, or any proceeds thereof or
(ii) any U.S. Fixed Assets acquired after the date of this
Indenture which do not constitute Permitted Collateral, the
Company shall make an Asset Sale Offer with the Net Cash Proceeds
received from such Asset Sale (without regard to the Twenty-Five
Million 

                                    56
