     document, but one such Person may certify or give an opinion with respect
     to some matters and one or more other such Persons as to other matters, and
     any such Person may certify or give an opinion as to such matters in one or
     several documents.
    
               Any certificate or opinion of an officer of the Company may be
      based, insofar as it relates to legal matters, upon a certificate or
      opinion of, or representations by, counsel, unless such officer knows, or
      in the exercise of reasonable care should know, that the certificate or
      opinion or representations with respect to the matters upon which his
      certificate or opinion is based are erroneous.  Any such certificate or
      opinion of counsel may be based, insofar as it relates to factual matters,
      upon a certificate or opinion of, or representations by, an officer or
      officers of the Company stating that the information with respect to such
      factual matters is in the possession of the Company, unless such counsel
      knows, or in the exercise of reasonable care should know, that the
      certificate or opinion or representations with respect to such matters are
      erroneous.     

               Where any Person is required to make, give or execute two or more
     applications, requests, consents, certificates, statements, opinions or
     other instruments under this Indenture, they may, but need not, be
     consolidated and form one instrument.


          SECTION 1.4.  Acts of Holders; Record Dates.
                        ----------------------------- 

               (a)  Any request, demand, authorization, direction, notice,
     consent, waiver or other action provided by this Indenture to be given or
     taken by Holders may be embodied in and evidenced by one or more
     instruments of substantially similar tenor signed by such 

 
                                                                              23

    
     Holders in person or by  one or more agents duly appointed in writing; and,
     except as herein otherwise expressly provided, such action shall become
     effective when such instrument or instruments are delivered to the Trustee
     and, where it is hereby expressly required, to the Company.  Such
     instrument or instruments (and the action embodied therein and evidenced
     thereby) are herein sometimes referred to as the "Act" of the Holders
     signing such instrument or instruments.  Proof of execution of any such
     instrument or of a writing appointing any such agent shall be sufficient
     for any purpose of this Indenture and (subject to Section 9.1) conclusive
     in favor of the Trustee and the Company, if made in the manner provided in
     this Section 1.4.     

               (b)  The fact and date of the execution of any such instrument or
     writing, or the authority of the Person executing the same, may be proved
     in any manner which the Trustee deems sufficient.

               (c)  The Company may, in the circumstances permitted by the Trust
     Indenture Act, fix any day as the record date for the purpose of
     determining the Holders entitled to give or take any request, demand,
     authorization, direction, notice, consent, waiver or other action, or to
     vote on any action, authorized or permitted to be given or taken by
     Holders.  If not set by the Company prior to the first solicitation of a
     Holder made by any Person in respect of any such action, or, in the case of
     any such vote, prior to such vote, the record date for any such action or
     vote shall be the 30th day (or, if later, the date of the most recent list
     of Holders required to be provided pursuant to Section 10.1) prior to such
     first solicitation or vote, as the case may be.  With regard to any record
     date, only the Holders on such date (or their duly designated proxies)
     shall be entitled to give or take, or vote on, the relevant action.

               (d)  The ownership of Securities shall be proved by the Security
     Register.


               (e)  Any request, demand, authorization, direction, notice,
     consent, waiver or other Act of the Holder of any Security shall bind every
     future Holder of the same Security and the Holder of every Security issued
     upon the registration of transfer thereof or in exchange therefor or in
     lieu thereof in respect of anything done, omitted or suffered to be done by
     the Trustee or the Company in reliance thereon, whether or not notation of
     such action is made upon such Security.


          SECTION 1.5.  Notices, Etc., to Trustee and Company.
                        ------------------------------------- 

               Any request, demand, authorization, direction, notice, consent,
     waiver or Act of Holders or other document provided or permitted by this
     Indenture to be made upon, given or furnished to, or filed with:

               (i)    the Trustee by any Holder or by the Company shall be
     sufficient for every purpose hereunder if made, given, furnished or filed
     in writing to or with the Trustee at its Corporate Trust Office, Attention:
     Corporate Trustee, ________________________, New Orleans, Louisiana _____;
     or

 
                                                                              24

               (ii)    the Company by the Trustee or by any Holder shall be
     sufficient for every purpose hereunder (unless otherwise herein expressly
     provided) if in writing and mailed, first-class postage prepaid, to the
     Company addressed to the attention of its Secretary at the address of its
     principal office specified in the first paragraph of this instrument or at
     any other address previously furnished in writing to the Trustee by the
     Company.


SECTION 1.6.  Notice to Holders; Waiver.
              ------------------------- 

               Where this Indenture provides for notice to Holders of any event,
     such notice shall be sufficiently given (unless otherwise herein expressly
     provided) if in writing and mailed, first-class postage prepaid, to each
     Holder affected by such event, at his address as it appears in the Security
     Register, not later than the latest date (if any), and not earlier than the
     earliest date (if any), prescribed for the giving of such notice.  In any
     case where notice to Holders is given by mail, neither the failure to mail
     such notice, nor any defect in any notice so mailed, to any particular
     Holder shall affect the sufficiency of such notice with respect to other
     Holders.  Where this Indenture provides for notice in any manner, such
     notice may be waived in writing by the Person entitled to receive such
     notice, either before or after the event, and such waiver shall be the
     equivalent of such notice.  Waivers of notice by Holders shall be filed
     with the Trustee, but such filing shall not be a condition precedent to the
     validity of any action taken in reliance upon such waiver.

               In case by reason of the suspension of regular mail service or by
     reason of any other cause it shall be impracticable to give such notice by
     mail, then such notification as shall be made with the approval of the
     Trustee shall constitute a sufficient notification for every purpose
     hereunder.

          SECTION 1.7.  Conflict with Trust Indenture Act.
                        --------------------------------- 

               If any provision hereof limits, qualifies or conflicts with a
     provision of the Trust Indenture Act that is required under such Act to be
     a part of and govern this Indenture, the latter provision shall control.
     If any provision of this Indenture modifies or excludes any provision of
     the Trust Indenture Act that may be so modified or excluded, the latter
     provision shall be deemed to apply to this Indenture as so modified or to
     be excluded, as the case may be.


          SECTION 1.8.  Effect of Headings and Table of Contents.
                        ---------------------------------------- 

               The Article and Section headings herein and the Table of Contents
     are for convenience only and shall not affect the construction hereof.

 
                                                                              25

          SECTION 1.9.  Successors and Assigns.
                        ---------------------- 

               All covenants and agreements in this Indenture by the Company
     shall bind its successors and assigns, whether so expressed or not.


          SECTION 1.10.  Separability Clause.
                         ------------------- 

               In case any provision in this Indenture or in the Securities
     shall be invalid, illegal or unenforceable, the validity, legality and
     enforceability of the remaining provisions shall not in any way be affected
     or impaired thereby.


          SECTION 1.11.  Benefits of Indenture.
                         --------------------- 

               Nothing in this Indenture or in the Securities, express or
     implied, shall give to any Person, other than the parties hereto and their
     successors hereunder and the Holders of Securities, any benefit or any
     legal or equitable right, remedy or claim under this Indenture.


          SECTION 1.12.  Governing Law.
                         -------------

                         -------------- 
    
               In any case where any Interest Payment Date, Maturity Date or
     Stated Maturity of any Security shall not be a Business Day, then
     (notwithstanding any other provision of this Indenture or of the
     Securities) payment of interest or principal need not be made on such date,
     but may be made on the next succeeding Business Day with the same force and
     effect as if made on the Interest Payment Date or Maturity Date, or at the
     Stated Maturity; provided, that no interest shall accrue for the period
     from and after such  Maturity Date or Stated Maturity, as the case may be.

     Indenture, against any incorporator, stockholder, officer or director, as

     incurred by, any incorporator, stockholder, officer or director, past,
     present or future, of the Company or of any successor corporation, either
     directly or indirectly through the Company or any successor corporation,

     by reason of any of the obligations, covenants or agreements contained in
     this Indenture or in any of the Securities, or to be implied herefrom or
     therefrom; and that all such personal liability is hereby expressly
     released and waived as a condition of, and as part of the consideration
     for, the execution of this Indenture and the issuance of the Securities.

          In the event that less than all of the Securities are to be redeemed
at any time, selection of Securities for redemption will be made by the Trustee
on a pro rata basis, by lot or by such method as the Trustee shall deem fair and
appropriate; provided, however, that no Securities of $1,000 or less shall be
redeemed in part.  Notice of redemption shall be mailed by first class mail at
least 30 but not more than 60 days before the redemption date to each Holder to
be redeemed at its registered address.  If any Security is to be redeemed in
part only, the notice of redemption that relates to such Security shall state
the portion of the principal amount thereof to be redeemed.  A new Security in a
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Security.  On and
after the redemption date, interest will cease to accrue on Securities or the
portion thereof called for redemption unless the Company defaults in the payment
of the redemption price or accrued interest.
    
          Sections 6.15 and 6.19 of the Indenture provide that after certain
Asset Sales and upon the occurrence of a Change of Control, and subject to
further limitations contained therein, the Company  may be required
to make an offer to purchase certain amounts of Securities in accordance
with the procedures set forth in the Indenture.     

          In order to secure the due and punctual payment of the principal of
and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same become due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Company, subject to certain
exceptions, has granted security interests in and 

 
                                                                              31

    
Liens on the Collateral owned by it to the Collateral Agent for the benefit of
the Holders pursuant to the Indenture and the Security Documents.  The Recourse
Subsidiaries of the Company shall execute a Subsidiary Guarantee to guarantee
the obligations of the Company with respect to the Securities.  The obligations
of a Recourse Subsidiary under the Subsidiaries Guarantee will be secured by the
Collateral assigned by such Subsidiary pursuant to  a Subsidiary Security
Agreement.     

          Each Holder, by accepting a Security, agrees to all of the terms and
provisions of the Security Documents, as the same may be amended from time to
time pursuant to the respective provisions thereof and the Indenture.
    
          The Trustee, the Collateral Agent and each Holder acknowledges that a
release of any of the Collateral or any Lien strictly in accordance with the
terms and provisions of the Indenture and Security Documents  will not
be deemed for any purpose to be an impairment of the Security under the
Indenture.     
    
          If an Event of Default (other than an Event of Default specified in
Section 8.1(vii) or (viii)) occurs and is continuing, the Trustee or the Holders
of at least 25% of the principal amount of the Outstanding Securities by notice
to the Company (and to the Trustee if such notice is given by the Holders) may
declare the principal amount and accrued interest on the Securities to be
immediately due and payable.  If an Event of Default specified in Section
8.1(vii) or (viii) occurs, the  principal amount and accrued interest shall ipso
facto become and be immediately due and payable on all Outstanding Securities
without any declaration or other act on the part of the Trustee or any Holder. 
The Holders of a majority in principal amount of the then Outstanding Securities
by notice to the Trustee and the Company may rescind an acceleration and its
consequences if the Company has paid or deposited with the Trustee a sum
sufficient to pay all amounts due, other than amounts due by declaration of
acceleration, and all existing Events of Default, other than the nonpayment of
the principal of the Securities which have became due solely by such declaration
of acceleration, have been cured or waived.  The Holders of a majority in
principal amount of the outstanding Securities also have the right to waive
certain past defaults under the Indenture, except a default in the payment of
the principal of, premium, if any, or interest on the Security, or in respect of
a covenant or a provision which cannot be modified or amended without the
consent of all Holders.     
    
          From time to time, the Company when authorized by a Board Resolution,
and the Trustee (or the Collateral Agent, if a party thereto), may, without the
consent of  any Holders, amend, waive, or supplement the Indenture, the Security
Documents or the Securities for certain specified  purposes, including, among
other things, curing ambiguities, defects, or inconsistences, maintaining the
qualification of the Indenture under the Trust Indenture Act, making any change
that does not adversely affect the rights of any Holder or mortgaging, pledging,
or granting a security interest in favor of the Collateral Agent as additional
security for the payment and performance of the obligations of the Company under
the Indenture, in any property or assets, including any which are required to be
mortgaged, pledged or hypothecated, or in which a security interest is required
to be granted, to the Collateral Agent pursuant to any Security Document or 
     


 
                                                                              32

    
otherwise; provided, that the Company delivers to the Trustee an Opinion of
Counsel stating that such change does not adversely affect the rights of any
Holder.  Other amendments and modifications of the Indenture, the Securities or
the Security Documents may be made by the Company, the Collateral Agent (if a
party thereto) and the Trustee with the consent of the Holders of not less than
a majority of the aggregate principal amount of the Outstanding Securities;
provided, that no such modification or amendment may, without the consent of the
Holder of each Outstanding Security affected thereby, (i) change the Stated
Maturity of the principal of, or any installment of interest on, any Security,
or alter the redemption provisions or reduce the principal amount thereof or the
rate of interest thereon, or change the place of payment where, or the coin or
currency in which, any Security or interest thereon is payable, or impair the
right to institute suit for the enforcement of any such payment on or after the 
Maturity Date thereof; or (ii) reduce the percentage in principal amount of the
Outstanding Securities, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture; or
(iii) modify any of the provisions of  Section 8.8 , 8.13 or 11.2, except to
increase any such percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the Holder of each
Outstanding Security affected thereby; or (iv) affect the ranking of the
Securities or the Liens in favor of the Trustee, the Collateral Agent and the
Holders in a manner adverse to the Holders or release all or substantially all
of the Collateral.
         
          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of  and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.     

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent will pay the money back to the
Company at its request.  After that, Holders entitled to the money must look to
the Company for payment as unsecured general creditors.
    
          As provided in the Indenture and subject to certain limitations set
forth therein (including in case of any Global Security, certain additional
limitations)  and as may be set forth on the face hereof, the transfer of this
Security is registrable in the Security Register upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place
where the principal of and interest on this Security are payable, duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar, duly executed by the Holder hereof or
his attorney duly authorized in writing, and thereupon one or more new
Securities in an authorized denomination and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.     

          The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture 

 
                                                                              33
    
and subject to certain limitations therein and herein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of different
authorized denominations, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require appropriate endorsements and the
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith, other than exchanges pursuant to Section 3.4 or
11.6 not including any transfer.  During the period of 15 days preceding any
Interest Payment Date or Maturity Date, the Company shall not be required to
register the transfer of or to exchange any Securities.  In addition, the
Company shall not be required (i) to register the transfer of or to exchange any
Securities for a period of 15 days immediately preceding any date fixed for any
selection of Securities of such series to be redeemed and (ii) to register the
transfer of or to exchange any Securities selected for redemption, except the
unredeemed portion of any Security being redeemed in part.     

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          The Indenture and the Securities endorsed thereon shall be governed by
and construed in accordance with the laws of the State of New York.

          When a successor corporation assumes all the obligations of its
predecessor under the Securities and the Indenture and the transaction complies
with the terms of Article VII of the Indenture, the predecessor corporation will
be released from those obligations.

          The Trustee, in its individual or any other capacity, may make loans
to, accept deposits and pledges from, and perform services for the Company or
its Affiliates, and may otherwise deal with the Company or its Affiliates, as if
it were not Trustee.

          Directors, officers, employees or shareholders of the Company shall
not have any liability for any obligations of the Company under the Securities,
the Indenture or the Security Documents or for any claim based on, in respect
of, or by reason of, such obligation or their creation.  The Holder of this
Security, or any beneficial interests in this Security, hereby waives and
releases all such liability.  Such waiver and release are part of the
consideration for the issue of the Securities.

    
          Customary abbreviations may be used in the name of a holder or an
assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with rights of survivorship and not as
tenants in common), CUST (= custodian), and U/G/M/A (= Uniform Gifts to Minors
Act).     

 
                                                                              34
    
          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Holders.  No representation is made as
to the accuracy of such numbers either as printed in the Securities or as
contained in any notice of redemption, and reliance may be placed only on the
other identification numbers placed thereon.

                                This is one of the Securities

SECTION 3.1.  Title and Terms.
              --------------- 
    
          The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $75,000,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Securities .  Subject to
Section 3.5, the Securities will be represented by a Global Security in the name

          The principal of and interest on the Securities shall be payable at
the office or agency of the Paying Agent in The City of New Orleans, maintained
for such purpose; provided, however, that at the option of the Company payment
of interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register;  provided,
further, that a Holder of $10,000,000 in aggregate principal amount of the
Securities shall be entitled to receive payments of interest by wire transfer in
immediately available funds (but only if appropriate payment instructions have
been received in writing by the Paying Agent not less than 15 calendar days
prior to the applicable Interest Payment Date).

          Notwithstanding any other provision of this Section 3.1, if the
Security is in the form of a Global Security, immediately available funds for
the payment of the principal of (and premium, if any) and interest on the
Security due on any Interest Payment Date or Maturity Date, as the case may be,
will be made available to the Paying Agent to permit the Paying Agent to pay
such funds to the Depositary on such respective dates.  The Depositary will
allocate and pay such funds to the owners of beneficial interests in the
Security in accordance with its existing operating procedures.
    
          The Securities shall be subject to redemption and repurchase by
the Company as provided  herein.     

SECTION 3.2.  Denominations.

            ---------- 

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or its
Chief Financial Officer, under its corporate seal reproduced thereon and
attested by its Secretary or one of its Assistant Secretaries.  The signature of
any of these officers on the Securities may be manual or facsimile.

                                                                              36

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwith-standing that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices on the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authen-ticate and deliver such Securities as in
this Indenture provided and not otherwise.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.


SECTION 3.4.  Temporary Securities.
              -------------------- 

          Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 6.2, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations.  Until so exchanged the temporary Securities shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities.

 
                                                                              37

SECTION 3.5.  Registration; Registration of Transfer and
              ------------------------------------------
            Exchange.
            -------- 
    
          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 6.2 being herein sometimes
collectively  referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed  Security Registrar  for the purpose of registering Securities
and transfers of Securities as herein provided.     

          Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 6.2 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate principal
amount.

          Notwithstanding any other provision of this Section 3.5, unless and
until it is exchanged in whole or in part for Securities in definitive form, a
Global Security representing all or a portion of the Securities may not be
transferred except as a whole by the Depositary to a nominee of such Depositary
or by a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor Depositary
for such series or a nominee of such successor Depositary.  Unless otherwise
provided as contemplated by Section 3.1 with respect to any series of Securities
evidenced in whole or in part by a Global Security, the Depositary may not sell,
assign, transfer or otherwise convey any beneficial interest in a Global
Security evidencing all or part of the Securities of such series unless such
beneficial interest is in an amount equal to an authorized denomination for the
Securities.

          If at any time the Depositary for the Securities notifies the Company
that it is unwilling or unable to continue as a Depositary for the Securities or
if at any time the Depositary for Securities shall no longer be registered or in
good standing under the Exchange Act or other applicable statute or regulation,
the Company shall appoint a successor Depositary with respect to the Securities.
If a successor Depositary for the Securities is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
condition, the Company will execute, and the Trustee, upon the written request
or authorization of any officer of the Company, will authenticate and deliver
Securities in definitive form in an aggregate principal amount equal to the
principal amount of the Global Security representing Securities in exchange for
such Global Security.

          In the event that (i) the Company at any time and in its sole
discretion determines that the Securities issued in the form of a Global
Security shall no longer be represented by such Global Security or (ii) there
shall have occurred and be continuing a Default or an Event of Default, the
Company will execute, and the Trustee, upon the written request or authorization
of any officer of the Company, will authenticate and 

 
                                                                              38

deliver Securities in definitive form and in an aggregate principal amount equal
to the principal amount of the Global Security representing the Securities in
exchange for such Global Security.

          The Depositary may surrender a Global Security in exchange, in whole
or in part, for Securities in definitive form on such terms as are acceptable to
the Company and such Depositary.  Thereupon, the Company shall execute and the
Trustee shall authenticate and deliver, without charge,

               (i)    to each Person specified by the Depositary, a new Security
     or Securities of the same series in definitive form in an aggregate
     principal amount equal to and in exchange for such Person's beneficial
     interest in the surrendered Global Security; and

               (ii)    to the Depositary, a new Global Security in a
     denomination equal to the difference, if any, between the principal amount
     of the surrendered Global Security and the aggregate principal amount of
     Securities of such series delivered in definitive form to Holders pursuant
     to clause (i) above.

          Upon the exchange of a Global Security for Securities in definitive
form, such Global Security shall be cancelled by the Trustee.  Securities issued
in definitive form in exchange for a Global Security pursuant to this Section
3.4 shall be registered in such names and in such authorized denominations as
the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee.  The Trustee shall
deliver such Securities in definitive form to the Person in whose name such
Securities are so registered.

          At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency.  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar, duly executed by the
Holder thereof or his attorney duly authorized in writing.

 
                                                                              39

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4 or 11.6 not involving any transfer.

          During the period of 15 days preceding any Interest Payment Date or
Maturity Date, the Company shall not be required to register the transfer of or
to exchange any Securities.  In addition, the Company shall not be required (i)
to register the transfer of or to exchange any Securities for a period of 15
days immediately preceding any date fixed for any selection of Securities of
such series to be redeemed and (ii) to register the transfer of or to exchange
any Securities selected for redemption, except the unredeemed portion of any
Security being redeemed in part.

SECTION 3.6.  Mutilated, Destroyed, Lost and Stolen Securities.
              ------------------------------------------------ 

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section 3.6, 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 (including the fees and expenses of the Trustee) connected therewith.

          Every new Security issued pursuant to this Section 3.6 in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

 
                                                                              40

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.


SECTION 3.7.  Payment of Interest; Interest Rights Preserved.
              ---------------------------------------------- 

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities (or their respective
     Predecessor Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which shall
     be fixed in the following manner.  The Company shall notify the Trustee in
     writing of the amount of Defaulted Interest proposed to be paid on each
     Security and the date of the proposed payment, and at the same time the
     Company shall deposit with the Trustee an amount of money equal to the
     aggregate amount proposed to be paid in respect of such Defaulted Interest
     or shall make arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when deposited to be
     held in trust for the benefit of the Persons entitled to such Defaulted
     Interest as in this Clause provided.  Thereupon the Trustee shall fix a
     Special Record Date for the payment of such Defaulted Interest which shall
     be not more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the Trustee
     of the notice of the proposed payment.  The Trustee shall promptly notify
     the Company of such Special Record Date and, in the name and at the expense
     of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder at his address as it appears in
     the Security Register, not less than 10 days prior to such Special Record
     Date.  Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such Defaulted Interest
     shall be paid to the Persons in whose names the Securities (or their
     respective Predecessor Securities) are registered at the close of business
     on such Special Record Date and shall no longer be payable pursuant to the
     following Clause (2).

          (2) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities 

 
                                                                              41

     exchange on which the Securities may be listed, and upon such notice as may
     be required by such exchange, if, after notice given by the Company to the
     Trustee of the proposed payment pursuant to this Clause, such manner of
     payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.


SECTION 3.8.  Persons Deemed Owners.
              --------------------- 

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 3.7) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.


SECTION 3.9.  Cancellation.
              ------------ 

          All Securities surrendered for payment, redemption, repurchase,
registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it.  The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture.  All cancelled
Securities held by the Trustee shall be destroyed and certification of their
destruction delivered to the Company unless by a Company Order the Company shall
direct that cancelled Securities be returned to it.


SECTION 3.10.  Computation of Interest.
               ----------------------- 

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

 
                                                                              42

SECTION 3.11.  Paying Agent.
               ------------ 

          The Company initially appoints the Trustee as a Paying Agent for the

time, and may appoint itself as a Paying Agent.  The Company shall deliver

          The Trustee shall make the selection from the Outstanding Securities

          At least 30 days but not more than 60 days prior to a redemption date,
the Company shall mail or cause the mailing of a notice of redemption by first-

          (6) if any Security is being redeemed in part, the portion of the
     principal amount (equal to $1,000 or any integral multiple thereof) of such
     Security to be redeemed and that, on and after the redemption date, upon
     surrender of such Security, a new Security or Securities in principal
     amount equal to the unredeemed portion thereof shall be issued without

          Once notice of redemption is mailed, Securities called for redemption
become due and payable on the redemption date and at the redemption price and
shall cease to bear interest from and after the redemption date (unless the
Company shall default in the payment of the redemption price or accrued
interest).  Upon surrender to the Paying Agent, such Securities shall be paid at
the redemption price, plus accrued interest to the redemption date; provided,
that if the redemption date is ________ 15 or ________ 15, then the interest
payable on such date shall be paid to the Holder of record on the next preceding

sufficient to pay the redemption price of and accrued interest on all Securities
or portions thereof to be redeemed on the redemption date.

          If any Security surrendered for redemption in the manner provided in
the Securities shall not be so paid on the redemption date due to the failure of
the Company to deposit sufficient funds with the Paying Agent, interest shall
continue to accrue from the redemption date until such payment is made on the
unpaid principal and, to the extent lawful, on any interest not paid on such
unpaid principal, in each case at the date and in the manner provided in the

any time the Company shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
address of the Trustee as set forth in Section 1.5 hereof.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, 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
City of New Orleans, Louisiana for such purposes.      

 
                                                                              47

business of the Company or such Subsidiary and (b) the loss of such right,
license or franchise or the dissolution of such Subsidiary is not adverse in any
material respect to the Holders.


SECTION 6.4.  Payment of Taxes and Other Claims;

            Tax Consolidation.

     any shares of Capital Stock of any of the  Company's Subsidiaries directly
     owned by the Company, in either case with an aggregate fair market value in

     Subsidiaries would not be permitted to incur or become liable with respect
     to at least $1.00 of additional Indebtedness as determined in accordance
     with Section 6.9; or (iii) the aggregate amount of all Restricted Payments
     made by the Company or any of its Subsidiaries (the amount expended or

     fair market value as determined in good faith by the Board of Directors of
     the Company, whose determination shall be conclusive and evidenced by a
     Board Resolution delivered to the Trustee) from and after the date of the
     Indenture, through and including the date on which such Restricted Payment
     is made, would exceed the sum of:

               (i)    the aggregate of 50% of the Company's Consolidated Net

     the amount of 

 
                                                                              55

     including Capital Stock other than Disqualified Stock issued upon
     conversion of, or exchange for, Disqualified Stock or securities other than
     its Capital Stock), and upon the exercise of warrants and rights to

     aggregate net cash proceeds received by the Company (x) from the issuance
     of its Capital Stock upon the conversion of, or exchange for, securities
     evidencing Indebtedness of the Company, shall be calculated on the
     assumption that the gross proceeds from such issuance are equal to the
     accreted principal amount (or, if discounted Indebtedness, the accredited
     principal amount) of Indebtedness evidenced by such securities converted or
     exchanged and (y) upon the conversion or exchange of other securities of
     the Company shall be equal to the aggregate net proceeds of the original
     sale of the securities so converted or exchanged if such proceeds of such
     original sale were not previously included in any calculation for the
     purposes of this clause (ii), plus any additional sums payable upon
     conversion or exchange.      

          Notwithstanding the foregoing, this provision shall not prevent (i)
the payment of any dividend within 60 days after the date of its declaration (if
the declaration of such dividend was permitted by the foregoing provision at the
time of such declaration); or (ii) the repurchase, retirement or other
acquisition of any shares of the Company's Capital Stock, or any option, warrant
or other right to purchase shares of the Company's Capital Stock, or the
repayment of any Indebtedness of the Company solely in exchange for shares of,
or out of the proceeds of a substantially contemporaneous issuance of, Capital
Stock (other than Disqualified Stock).

holder or with any Affiliate of the Company (other than a Wholly-Owned Recourse

Person as determined by the Board of Directors of the Company or a Subsidiary,
such approval to be evidenced by a Board Resolution.      

 
                                                                              56

               (vii)    that if Securities in a principal amount in excess of

SECTION 6.20.  Limitations as to Non-Recourse Subsidiaries.
               ------------------------------------------- 

          The Company shall not permit any Non-Recourse Subsidiary to create,
assume, incur, guarantee or otherwise become liable in respect to any
Indebtedness unless the lender in respect thereof has effectively waived all
claims and/or recourse on or in respect of such Indebtedness against the Company
or any other Subsidiary of the Company, including, without limitation, a waiver
by such lender of the benefits of the provisions of Section 1111(b) of the

delivered to the Trustee an Opinion of Counsel (by a law firm of national
repute) and a Board Resolution confirming the foregoing, in each case in form

otherwise transfer to any Non-Recourse Subsidiary any asset which is essential 
to the steelmaking operations of the Company or its Subsidiaries (other than
Non-Recourse Subsidiaries).  The Company will not permit any Non-Recourse
Subsidiary to acquire any such essential asset, and the Company and its
Subsidiaries will not purchase any Non-Recourse Subsidiary, unless in the
judgment of the Board of Directors of the Company the creation and operation of
the Non-Recourse Subsidiary and its  acquisition of such assets are neither
intended nor reasonably expected to adversely affect the financial condition,
business, prospects or operations of the Company and its Subsidiaries (other
than Non-Recourse Subsidiaries).      



SECTION 6.21.  Impairment of Security Interest.
               ------------------------------- 

          The Company shall not, and shall not permit any of its Subsidiaries
to, take or omit to take any action, which action or omission  would have the
result of affecting or impairing the security interest in favor of the
Collateral Agent  with respect to the Collateral, and the Company shall not
grant to any Person (other than the Collateral Agent and the Holders) any
interest whatsoever in the Collateral, except, in either case, as expressly
permitted by Section 6.10 and the Security Documents.      


SECTION 6.22.  Conflicting Agreements.
               ---------------------- 

          The Company shall not, and shall not permit any of its Subsidiaries
to, enter into any agreement or instrument that by its terms expressly (i)
prohibits the Company from redeeming or otherwise making any payments on or in
respect of the Securities in accordance with the terms thereof or hereof, as in
effect from time to time, or (ii) requires that the proceeds received from the
sale of any Collateral be applied to repay, redeem or otherwise retire any
Indebtedness of any Person other than the Indebtedness represented by the
Securities, except as expressly permitted hereby or by the Security Documents.
     

 
                                                                              64

Subsidiaries to, amend, modify or supplement, or permit or consent to any
amendment, modification or supplement of, any of the Security Documents in any
way which would be adverse to the Holders or which would constitute a Default
hereunder or a default under any Security Document.


SECTION 6.24.  Inspection.
               ---------- 

          The Company shall, and shall cause each of its Subsidiaries to, permit
authorized representatives of the Trustee and the Collateral Agent to visit and
inspect the properties of the Company or its Subsidiaries, and any or all books,
records and documents in the possession of the Company relating to the
Collateral, and to make copies and take extracts therefrom and to visit and
inspect the Collateral, all upon reasonable prior notice and at such reasonable
times during normal business hours and as often as may be reasonably requested.



SECTION 6.25.  Use of Proceeds.
               --------------- 

          The Company shall use  the proceeds of the Securities in the manner
described in the Prospectus.  The Company shall not use any part of such
proceeds to purchase or carry any margin stock or to extend credit to others for
the purpose of purchasing or carrying any margin stock.  Neither the issuance of
any Security nor the use of the proceeds thereof shall violate or be
inconsistent with the provisions of Regulations G, T, U or X of the Board of
Governors of the Federal Reserve System.      

SECTION 6.26.  Money for Security Payments to Be Held in Trust.
               ----------------------------------------------- 

          If the Company shall at any time act as its own Paying Agent, it will,
on or before each due date of the principal of or interest on any of the
Securities, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

          Whenever the Company shall have one or more Paying Agents, it will, on
or prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

          The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree 

 
                                                                              65

with the Trustee, subject to the provisions of this Section, that such Paying
Agent will (i) comply with the provisions of Section 317 of the Trust Indenture
Act applicable to it as a Paying Agent and (ii) during the continuance of any
default by the Company (or any other obligor upon the Securities) in the making
of any payment in respect of the Securities, upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent as such.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same  terms as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.     

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or interest on any
Security and remaining unclaimed for two years after such principal or interest
has become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in New Orleans and New York City, or give by mail to
each Holder, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication or mailing, any unclaimed balance of such money then remaining will
be repaid to the Company.

     such transaction or series of transactions, such supplemental indenture
     complies with this covenant and that all conditions precedent in the
     Indenture relating to the transaction or series of transactions have been
     satisfied.

          Notwithstanding the foregoing, clause (iv) shall not prohibit a
transaction, the principal purpose of which is (as determined in good faith by
the Board of Directors of the Company and evidenced by the Board Resolution or
Board Resolutions thereof) to change the state of incorporation of the Company,
and such transaction does not have as one of its purposes the evasion of the
limitation on merger, consolidations and sales of assets  contained
herein.  Nothing contained in this Article shall be deemed to prevent the
Company or any Subsidiary from granting a security interest in, or a mortgage or
Lien upon, or otherwise encumbering, any of its assets, subject to the
limitations on Liens set forth in Section 6.10.  Notwithstanding the
foregoing, the Company and its Recourse Subsidiaries may not consolidate with or
merge into a Non-Recourse Subsidiary or convey, sell, assign, transfer or lease
all or substantially all of their properties and assets      

 
                                                                              67

    (determined, with respect to the Company, on a consolidated basis for the
Company and its Subsidiaries taken as a whole) in one transaction or a series of
transactions to any Non-Recourse Subsidiary, or permit any Non-Recourse
Subsidiary to consolidate with or merge into the Company or any of its Recourse
Subsidiaries or convey, sell, assign, transfer or lease all or substantially all
of such Non- Recourse Subsidiary's properties and assets in one transaction or a
series of transactions to the Company or any of its Recourse Subsidiaries.      


SECTION 7.2.  Surviving Person Substituted.
              ---------------------------- 

          Upon any consolidation or merger or any transfer of all or
substantially all of the assets of the Company in accordance with Section 7.1,
the surviving person formed by such consolidation or into which the Company is
merged or to which such transfer is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under this Indenture
with the same effect as if such surviving person had been named as the Company
herein.

                               EVENTS OF DEFAULT

SECTION 8.1.  Events of Default.
              ----------------- 

          "Event of Default", wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):

               (i)    default in the payment of any interest upon any Security
     when it becomes due and payable, and continuance of such default for a
     period of 30 days; or

               (ii)    default in the payment of the principal, or premium, if
     any, of any Security on a Maturity Date; or

               (iii)    default in the performance, or breach, of any covenant
     or agreement described in Sections 6.15 or  6.19 of this Indenture, and
     continuance of such default or breach for a period of five days; or      

               (iv)     failure to observe or perform any covenant,
     condition or agreement in the Securities, the Indenture or the Security
     Documents (other than as described in clause (i), (ii) or (iii)) and such
     failure to observe or perform continues for a period of 30 days after there
     has been given to the Company by the Trustee,      

 
                                                                              68
     or has been received by the Company and the Trustee from the
     Holders of at least 25% of the principal amount of the Securities then
     outstanding, a written notice specifying such default, demanding that it be
     remedied and stating that the notice is a "Notice of Default", unless, with
     respect to defaults under the Security Documents, the remedy or cure of
     such default requires work to be performed, acts to be done or conditions
     to be removed which cannot, by their nature, reasonably be performed, done
     or removed within such 30-day period, or if such remedy or cure is
     prevented by causes outside of the control or responsibility of the
     Company, in which case no "Event of Default" shall be deemed to exist 
     until the date that is 90 days after such written notice so long as the
     Company shall have commenced cure within such 90-day period and shall
     diligently prosecute the same to completion; or      

               (v)    a default under any bond, debenture, note or other
     evidence of Indebtedness for money borrowed (other than the Securities) by
     the Company or any Recourse Subsidiary of the Company or under any
     mortgage, indenture or instrument (other than this Indenture or the
     Securities) under which there may be issued or by which there may be
     secured or evidenced any Indebtedness for money borrowed by the Company
     (including, in each case, Guarantees of the  Company and its Recourse
     Subsidiaries), whether such Indebtedness or Guarantee now exists or shall
     hereafter be created, which default shall constitute a failure to pay any
     portion of the principal of such Indebtedness in a principal amount of at
     least $1,000,000 when due and payable after the expiration of any
     applicable grace period with respect thereto; or      

               (vi)    a default under any bond, debenture, note or other
     evidence of Indebtedness for money borrowed (other than the Securities) by
     the Company or any Recourse Subsidiary of the Company or under any
     mortgage, indenture or instrument (other than this Indenture or the
     Securities) under which there may be issued or by which there may be
     secured or evidenced any Indebtedness for money borrowed by the Company
     (including, in each case, Guarantees of the Company and its Recourse
     Subsidiaries), whether such Indebtedness or Guarantee now exists or shall
     hereafter be created if (i) as a result of such event of default the
     maturity of such Indebtedness has been accelerated prior to its stated
     maturity and (ii) the principal amount of such Indebtedness, together with
     the principal amount of any other Indebtedness of the Company and its
     Subsidiaries the maturity of which has been so accelerated, aggregates
     $1,000,000 or more; or      
          
               (vii)    the Company or any Subsidiary (other than a Non-Recourse
     Subsidiary, unless such action or proceeding adversely affects the
     interests of the Company or any Recourse Subsidiary) pursuant to or within
     the meaning of any Bankruptcy Law (a) commences a voluntary case or
     proceeding; (b) consents to the entry of an order for relief against it in
     an involuntary case or proceeding; (c) consents to the appointment of a
     Custodian of it or for all or substantially all of its property; (d) makes
     a general assignment for the benefit of its creditors; or (e) admits in
     writing its inability to pay its debts as the same become due; or      
          

 
                                                                              69

               (viii)    a court of competent jurisdiction enters an order or
     decree under any Bankruptcy Law that (a) is for relief against the Company
     or any Subsidiary in an involuntary case; (b) appoints a Custodian of the
     Company or any Subsidiary for all or substantially all of its property; or
     (c) orders the liquidation of the Company or any Subsidiary; provided, that
      clauses (a), (b) and (c) shall not apply to a Non-Recourse
     Subsidiary, unless such action or proceeding adversely affects the
     interests of the Company or any Recourse Subsidiary  and in any
     such case the order or decree remains unstayed and in effect for 60
     days; or      

               (ix)    the Company or any Subsidiary shall fail to discharge any
     one or more judgments not covered by insurance (from which no further
     appeal may be taken) in excess of $1,500,000, and such judgments shall
     remain in force, undischarged, unsatisfied, unstayed and unbonded for more
     than 30 days; or

               (x)    the Security Documents shall cease, for any reason, to be
     in full force and effect or shall cease to be effective to grant a first
     priority perfected Lien on the Collateral, subject to the exceptions
     permitted by Section 6.10.


SECTION 8.2.   Acceleration of Maturity; Rescission and Annulment.
               -------------------------------------------------- 

          If an Event of Default (other than an Event of Default specified in
subparagraph (vii) or (viii)  of Section  8.1) occurs and is continuing, then
and in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities may declare the principal of and
accrued interest  on all the Securities to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such principal shall become immediately due and
payable.  If an Event of Default specified in clause (vii) or (viii)  of Section
8.1 occurs, the principal amount and accrued interest shall ipso facto become
and be immediately due and payable on all Outstanding Securities without any
declaration or other act on the part of the Trustee or any Holder.      

          At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a majority
in principal amount of the Outstanding Securities, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:

               (i)    the Company has paid or deposited with the Trustee a sum
     sufficient to pay

                  (a) all overdue interest on all Securities;

                  (b)  the principal of any Securities which have become due
             otherwise than by such declaration of acceleration and interest
             thereon at the rate borne by the Securities;

 
                                                                              70

               (c) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate borne by the Securities;
          and

               (d) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel;

     and

               (ii)    all Events of Default, other than the non-payment of the
     principal of Securities which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 8.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.



SECTION 8.3.   Collection of Debt and Suits for
               ---------------------------------
               Enforcement by Trustee
               ----------------------

          The Company covenants that if:

          (i)  default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 30 days; or

          (ii)  default is made in the payment of the principal of any Security
     on a Maturity Date,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest, and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal and on
any overdue interest, at the rate borne by the Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or the Security
Documents or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

          Each Holder, by accepting a Security, acknowledges that the exercise
of remedies by the Trustee with respect to the Collateral is subject to the
terms and 

 
                                                                              71

conditions of the Security Documents and the proceeds received upon
realization of the Collateral shall be applied by the Trustee in accordance with
Section 8.6.


SECTION 8.4.     Trustee May File Proofs of Claims.
                 --------------------------------- 

          In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding.  In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 9.7.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.


SECTION 8.5.     Trustee May Enforce Claims
                 --------------------------
                 Without Possession of Securities.
                 -------------------------------- 

          All rights of action and claims under this Indenture,  the Security
Documents, or the Securities may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities in
respect of which such judgment has been recovered.


SECTION 8.6.   Application of Money Collected.
               ------------------------------ 

          Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or interest,
upon presentation of the 

 
                                                                              72

Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

               FIRST:  To the payment of all amounts due the Trustee under
          Section 9.7 and, in its capacity as Collateral Agent, for amounts due
          under the Security Documents;

               SECOND:  To the payment of unpaid interest accrued on the
          Securities in respect of which or for the benefit of which such money
          has been collected, ratably, without preference or priority of any
          kind, according to the amounts due and payable on such Securities for
          interest;

               THIRD:  To the payment of the unpaid principal of the Securities
          in respect of which or for the benefit of which such money has been
          collected, ratably, without preference or priority of any kind,
          according to the amounts due and payable on such Securities for
          principal; and

               FOURTH:  To the Company or any other obligors on the Securities,
          as their interests may appear, or as a court of competent jurisdiction
          may direct.


SECTION 8.7.  Limitation on Suits.
              ------------------- 

          Except as provided in Section 8.8, no Holder of any Security shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

          (i)  such Holder has previously given written notice to the Trustee of
     a continuing Event of Default;

          (ii)  the Holders of not less than 25% in principal amount of the
     Outstanding Securities shall have made written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

          (iii) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (iv)  the Trustee for 15 days after its receipt of such notice,
     request and offer of indemnity has failed to institute any such proceeding;
     and

 
                                                                              73

          (v)  no direction inconsistent with such written request has been
     given to the Trustee during such 15-day period by the Holders of a majority
     in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whether by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

          The foregoing limitations shall not apply to a suit instituted by a
Holder for the enforcement of the payment of principal of or accrued interest on
such Securities on or after the respective due dates set forth in such
Securities.


SECTION 8.8.       Unconditional Right of Holders to
                   ---------------------------------
                   Receive Principal and Interest.
                   ------------------------------ 

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and (subject to Section 3.7) interest on
such Security on the respective Maturity Dates expressed in such Security and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired or affected without the consent of such Holder, except to the
extent that the institution or prosecution of such suit or entry of judgment
therein would, under applicable law, result in the surrender, impairment or
waiver of the Lien of this Indenture and the Security Documents upon the
Collateral.


SECTION 8.9.     Restoration of Rights and Remedies.
                 ---------------------------------- 

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.


SECTION 8.10.     Rights and Remedies Cumulative.
                  ------------------------------ 

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the 

 
                                                                              74

extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise.  The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.


SECTION 8.11.     Delay or Omission Not Waiver.
                  ---------------------------- 

          No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.


SECTION 8.12.     Control by Holders.
                  ------------------ 

          The Holders of a majority in principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power  conferred on the Trustee; provided, that the Trustee may
refuse to follow any direction that:

               (i)    conflicts with any rule of law or with this Indenture;

               (ii)    the Trustee determines may be unduly prejudicial to the
     rights of another Holder; or

               (iii)    may involve the Trustee in personal liability unless the
     Trustee has indemnification satisfactory to it in its sole discretion
     against any loss or expense caused by it following such directions;

provided, further, that the Trustee may take any other action deemed proper by
the Trustee which is not inconsistent with such direction.


SECTION 8.13.     Waiver of Past Defaults.
                  ----------------------- 

          The Holders of not less than a majority in principal amount of the
Outstanding Securities may on behalf of the Holders of all the Securities waive
any past default hereunder and its consequences, except a default

               (i)    in the payment of the principal of or interest on any
     Security; or
 

 
                                                                              75

               (ii)  in respect of a covenant or provision hereof which under
     Article XI cannot be modified or amended without the consent of the Holder
     of each Outstanding Security affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.


SECTION 8.14.     Undertaking for Costs.
                  --------------------- 
    
          In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess reasonable
costs, including reasonable attorneys' fees, against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided, that
neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any
suit instituted by the Trustee, a suit by a Holder pursuant to Section 8.8, or a
suit by a Holder or Holders of more than 10% in aggregate principal amount of
the outstanding Securities.      


SECTION 8.15.     Waiver of Stay or Extension Laws.
                  -------------------------------- 

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.


SECTION 8.16.     Collection Suit by Trustee.

          If an Event of Default specified in Section 8.1(i) or 8.1(ii) or

obligor upon the Securities) for the whole amount of principal and accrued
interest remaining unpaid, together with interest overdue on principal and, to
the extent that payment of such interest is lawful, interest on overdue
installments of interest, in each case at the rate per annum borne by the
Securities, and such further amount as shall be sufficient to cover the costs
and expenses of collection,      

 
                                                                              76

                                  THE TRUSTEE

SECTION 9.1.     Certain Duties and Responsibilities.
                 ----------------------------------- 

          The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.  Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 9.1.  If an Event of Default has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Indenture and use the same degree of care and skill
in its exercise as a prudent person would exercise or use under the
circumstances in the conduct of its own affairs.


SECTION 9.2.     Notice of Defaults.
                 ------------------ 
    
          The Trustee shall give the Holders notice of any default hereunder as
and to the extent provided by Section 315(b) of the Trust Indenture Act.  Except
in the case of a Default or an Event of Default in payment of principal of or
interest on any Security (including the failure to make payments with respect to
redemptions, Asset Sale Offers or a Change of Control Offer), the Trustee may
withhold the notice if and so long as the Trustee in good faith determines that
withholding the notice is in the interest of Holders.      


SECTION 9.3.     Certain Rights of Trustee.
                 ------------------------- 
    
          Subject to Sections 315(a) through (d) of the Trust Indenture Act, the

                                                                              77

          (b)  any request or direction of the Company mentioned herein shall be
     sufficiently evidenced by a Company Request or Company Order and any
     resolution of the Board of Directors may be sufficiently evidenced by a
     Board Resolution;

          (c)  whenever in the administration of this Indenture the Trustee
     shall deem it desirable that a matter be proved or established prior to
     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, rely upon an Officers' Certificate;

          (d)  the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or

          (e) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

          (f)  the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney;
    
          (g)  the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; and      

          (h)  subject to Section 11.2 hereof, the Trustee may  (but shall not
     be obligated to), without the consent of the Holders, give any consent,
     waiver or approval required under the Security Documents or by the terms
     hereof with respect to the Collateral, but shall not without the consent of
     the Holders of a majority in aggregate principal amount of the Securities
     at the time outstanding (i) give any consent, waiver or approval or (ii)
     agree to any amendment or modification of the Security Documents, in each
     case, that shall have an adverse effect on the interests of any Holder. 
     The Trustee shall be entitled to request and conclusively rely on an
     Opinion of Counsel with respect to whether any consent,      

 
                                                                              78

     waiver, approval, amendment or modification shall have an adverse effect on
     the interests of any Holder.

                 ----------------------------
          or Issuance of Securities.
          ------------------------- 

               The recitals contained herein and in the Securities, except the
     Trustee's certificates of authentication, shall be taken as the statements
     of the Company, and the Trustee assumes no responsibility for their
     correctness.  The Trustee makes no representations as to the validity or
     sufficiency of this Indenture or of the Securities.  The Trustee shall not
     be accountable for the use or application by the Company of Securities or
     the proceeds thereof.


     SECTION 9.5.  May Hold Securities.
                   ------------------- 

               The Trustee, any Authenticating Agent, any Paying Agent, any
     Security Registrar or any other agent of the Company, in its individual or
     any other capacity, may become the owner or pledgee of Securities and,
     subject to Section 9.8 and 9.13, may otherwise deal with the Company with
     the same rights it would have if it were not Trustee, Authenticating Agent,
     Paying Agent, Security Registrar or such other agent.


     SECTION 9.6.  Money Held in Trust.
                   ------------------- 

               Money held by the Trustee in trust hereunder need not be
     segregated from other funds except to the extent required by law.  The
     Trustee shall be under no liability for interest on any money received by
     it hereunder except as otherwise agreed in writing with the Company.


     SECTION 9.7.  Compensation and Reimbursement.
                   ------------------------------ 

               The Company agrees:

               (i)    to pay to the Trustee from time to time reasonable
     compensation for all services rendered by it hereunder and under the
     Security Documents (which compensation shall not be limited by any
     provision of law in regard to the compensation of a trustee of an express
     trust);

               (ii)    except as otherwise expressly provided herein, to
     reimburse the Trustee upon its request for all reasonable expenses,
     disbursements and advances incurred or made by the Trustee in accordance
     with any provision of this Indenture or the Security Documents (including
     the reasonable compensation and the expenses and disbursements of its
     agents and counsel), 

 
                                                                              79

     except any such expense, disbursement or advance as
     may be attributable to its negligence or bad faith; and

               (iii)    to indemnify the Trustee for, and to hold it harmless
     against, any loss, liability or expense incurred without negligence or bad
     faith on its part, arising out of or in connection with the acceptance or
     administration of this Indenture or the Security Documents, including the
     costs and expenses of defending itself against any claim or liability in
     connection with the exercise or performance of any of its powers or duties
     hereunder or thereunder.      

          The Trustee shall notify the Company promptly of any claim asserted
against it for which it may seek indemnity.

          As security for the performance of the obligations of the Company
under this Section the Trustee shall have a Lien prior to the Securities on all
properties and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of or interest on particular Securities.

          If the Trustee incurs expenses or renders services after an Event of
Default specified in Section 8.1(vii) or (viii) occurs, the expenses and
compensation for the services will be intended to constitute expenses of
administration under any applicable Bankruptcy Law or other similar law.

          The Company's obligations under this Section 9.7 and any Lien arising
hereunder shall survive the resignation or removal of any Trustee, the discharge
of the Company's obligations pursuant to Articles IV or XII of this Indenture
and/or the termination of this Indenture.


SECTION 9.8.  Disqualification; Conflicting Interests.
              --------------------------------------- 

          If the Trustee has or shall acquire a conflicting interest within the
meaning of Section 310(b) of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture.


SECTION 9.9.  Corporate Trustee Required; Eligibility.
              --------------------------------------- 
    
          There shall at all times be a Trustee hereunder which shall be a
Person that is eligible pursuant to Section 310(a) of the Trust Indenture Act to
act as such and has a combined capital and surplus of at least $50,000,000 and
its Corporate Trust Office in New York City or New Orleans, Louisiana. If such
Person publishes reports of condition at least annually, pursuant to law or to
the requirements of said supervising or examining authority, then for the
purposes of this Section 9.9, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most
     

 
                                                                              80

recent report of condition so published.  If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section 9.9, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.


SECTION 9.10.  Resignation and Removal;
               ------------------------
               Appointment of Successor.
               ------------------------ 

          (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 9.11.

          (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

          (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Securities, delivered to the
Trustee and to the Company.

          (d)  If at any time:

               (i)    the Trustee shall fail to comply with Section 9.8 after
     written request therefor by the Company or by any Holder who has been a
     bona fide Holder of a Security for at least six months; or

               (ii)    the Trustee shall cease to be eligible under Section 9.9
     and shall fail to resign after written request therefor by the Company or
     by any such Holder; or

               (iii)    the Trustee shall become incapable of acting or shall be
     adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
     property shall be appointed or any public officer shall take charge or
     control of the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation;

then, in any such case, (1) the Company by a Board Resolution may remove the
Trustee, or (2) subject to Section 8.14, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board 

 
                                                                              81

Resolution, shall promptly appoint a successor Trustee.  If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee.

          (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 1.6.  Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

          (g)  Any resignation or removal of the Trustee pursuant to this
Indenture shall be deemed to be a resignation or removal of the Trustee in its
capacity as Collateral Agent under the Security Documents and any appointment of
a successor Trustee pursuant to this Indenture shall be deemed to be an
appointment of a successor Collateral Agent under the Security Documents and
such successor shall assume all of the obligations of the Trustee in its
capacity as Collateral Agent under the Security Documents.

SECTION 9.11.  Acceptance of Appointment by Successor.
               -------------------------------------- 

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder, subject nevertheless to its Lien, if any,
provided for in Section 9.7.  Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

          No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

 
                                                                              82

SECTION 9.12.  Merger, Conversion, Consolidation or
               ------------------------------------
               Succession to Business.
               ---------------------- 

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder; provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.


SECTION 9.13.  Preferential Collection of Claims Against Company.
               ------------------------------------------------- 

          If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of Section 311 of the Trust Indenture Act regarding the collection of
claims against the Company (or any such other obligor).


SECTION 9.14.  Appointment of Authenticating Agent.
               ----------------------------------- 

          The Trustee may appoint an Authenticating Agent or Agents which shall
be authorized to act on behalf of the Trustee to authenticate Securities issued
upon original issue and upon exchange, registration of transfer or partial
repurchase or pursuant to Section 3.6, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder.  Wherever reference
is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee's certificate of authentication, such reference shall
be deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section 9.14, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 9.14, such 

 
                                                                              83

Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 9.14, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 9.14, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders as their names and addresses appear in the Security Register.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent. 
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 9.14.

          The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 9.14, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 9.7.

          If an appointment is made pursuant to this Section 9.14, the
Securities may have endorsed thereon, in addition to the Trustee's certificate
of authentication, an alternative certificate of authentication in the following
form:

          This is one of the Securities described in the within-mentioned
Indenture.


                              TRUSTEE'S CERTIFICATE OF
                               AUTHENTICATION
                               This is one of the Securities
                               issued under the Indenture
                               described herein.

into and comply with the provisions of the Release Agreement in connection with
any sale or other disposition of the Collateral subject to the TBT Lease.

unreasonable manner.  Under no circumstances will any Holder or any portion of
the Collateral have any obligation, or be in any manner responsible to the
Company, the Tax Lessor, Meyers, Voest-Alpine or VAIC in respect of any loss
anticipated in connection with the TBT Lease and neither any portion of the

majority in principal amount of the Outstanding Securities obtain an Opinion of
Counsel from a law firm designated in such direction and shall be protected in
relying and acting thereon.      

          (c)  The Trustee is authorized and directed by the Holders to enter
into and comply with the provisions of the Intercreditor Agreement.  Compliance
with the Intercreditor Agreement shall in no event serve as the basis for any

unreasonable manner.  The Trustee is authorized to execute and deliver the
documents referred to in Section 2(c) of the Intercreditor Agreement upon
receipt of such documents and an Officer's Certificate and an Opinion of
Counsel, each to the effect that such documents comply with the requirements of
the Intercreditor Agreement and the conditions contained herein to the execution

preserve or protect its interests and the interests of the Holders in the
Collateral (including the power to institute and maintain suits or proceedings
to restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such

withdrawn by the Company (or by a Subsidiary of the Company if title to the
property damaged or taken was held by such Subsidiary, but only to the extent of
the Net Insurance Proceeds or Condemnation Proceeds relating thereto) and shall
be paid by the Trustee upon a Company Order to reimburse the Company or its
Subsidiary for expenditures made, or to pay costs incurred, by the Company or
its Subsidiary to repair, rebuild or replace the property destroyed, damaged or
taken, upon receipt by the Trustee of the following:

          (a)  an Officers' Certificate of the Company or its Subsidiary, dated

          construction of such repairs, rebuildings or replacements, or for
          labor, wages, materials or supplies in connection with the making
          thereof, which, if unpaid, might become the basis of a vendors',
          mechanics', laborers', materialmen's, statutory or other similar Lien
          upon any of such repairs, rebuildings or replacement, which Lien
          might, in the opinion of the signers of such certificate, materially

          replacements;

                    (iv)    that the property to be repaired, rebuilt or
          replaced is necessary or desirable in the conduct of the Company's or

          which such property has been or is to be used or operated by the
          Company or its Subsidiary, and whether the fair value to the Company
          or its Subsidiary, at the date of such acquisition of such part of
          such repairs, rebuildings or replacement is at least $25,000, or 1% of
          the aggregate principal amount of the Outstanding Securities;

                    (vi)    that no Default or Event of Default shall have
          occurred and be continuing; and

          delivered to the Trustee conform to the requirements of this Indenture
          and the Security Documents, and that, upon the basis of such request
          of the Company or its Subsidiary and the accompanying documents
          specified in this 

 
                                                                              97

          Section 13.2, all conditions precedent herein
          provided for relating to such withdrawal and payment have been
          complied with, and the Trust Moneys whose withdrawal is then requested
          may be lawfully paid over under this Section 13.2;

                    (ii)    that the Trustee has a valid and perfected Lien on
          such repairs, rebuilding and replacements, that the same and every
          part thereof are subject to no Liens prior to the Lien of the Security
          Documents, except Liens of the type permitted under the Security
          Documents to which the property so destroyed or damaged shall have
          been subject at the time of such destruction or damage; and

                    (iii)    that all of the Company's or its Subsidiary's
          right, title and interest in and to said repairs, rebuildings or
          replacements, or combination thereof, are then subject to the Lien of

Subsidiary of such repairs, rebuildings and replacements stated in such
Officers' Certificate (or in such Independent Appraiser's or Independent
Financial Advisor's certificate, if required by the Trust Indenture Act),
whichever is less; provided, however, that notwithstanding the above, so long as
no Default or Event of Default shall have occurred and be continuing, in the
event that any Net Insurance Proceeds or Condemnation Award for such property or
proceeds of such sale does not exceed the lesser of $25,000 or 1% of the
principal amount of the Outstanding Securities, and, in the good faith estimate
of the Company, such destruction or damage resulting in such Net Insurance
Proceeds or Condemnation Award does not detrimentally affect the value or use of
the applicable Collateral in any material respect, upon delivery to the Trustee
of an Officers' Certificate of the Company or its Subsidiary to such effect, the
Trustee shall release to the Company or its Subsidiary such Net Insurance
Proceeds or Condemnation Award for such property or proceeds of such sale, free
of the Lien hereof and of the Security Documents.

               ------------------- 

          Upon the Company's exercise of the option provided in Section 14.1
applicable to this Section 14.3, (i) the Company shall be released from its
obligations under Sections 6.9 through 6.25 and (ii) the occurrence of an event
specified in Section 8.1(iv) (with respect to any of Section 6.9 through 6.25),
8.1(v) and (vi)) shall not be deemed to be an Event of Default (hereinafter,
"covenant defeasance").  For this purpose, such covenant defeasance means that
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such Section, whether
directly, or indirectly by reason of any reference elsewhere herein to any such
Section or by reason of any reference in any such Section to any other provision
herein or in any other document, but the remainder of this Indenture and such
Securities shall be unaffected thereby.


SECTION 14.4.  Conditions to Defeasance or Covenant Defeasance.
               ----------------------------------------------- 

          Except as otherwise indicated below, the following shall be the
conditions to application of either Section 14.2 or Section 14.3 to the then
Outstanding Securities:

          The Company may exercise its legal defeasance option or its covenant
defeasance option only if:

          (1)  the Company shall irrevocably have deposited or caused to be
     deposited in trust with the Trustee (or another trustee satisfying the
     requirements of Section 9.9 who shall agree to comply with the provisions
     of this Article applicable to the Trustee) as trust funds in trust for the
     purpose of making the following payments, specifically pledged as security
     for, and dedicated solely to, the benefit of the Holders of such
     Securities, (A) money in an amount, or (B) U.S. Government Obligations
     which through the scheduled payment of principal and interest in respect
     thereof in accordance with their terms will provide, not later than one day
     before the due date of any payment, money in an amount sufficient to pay
     the principal of and each installment of interest on the Securities on the
     Maturity Date of such principal or Interest Payment Date, as the case may
     be, in accordance with the terms of this Indenture and of the Securities,
     or (C) a combination of (A) and (B)      

          (2)  the Company delivers to the Trustee a certificate from a
     nationally recognized firm of independent certified public accountants
     expressing their opinion      

 
                                                                             103

     that the payments of principal and interest when due and without
     reinvestment of the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity or redemption, as the case may be;      

          (3)  123 days pass after the deposit is made and during the 123-day
     period no Event of Default or Default relating to bankruptcy and insolvency
     events with respect to the Company occurs which is continuing at the end of
     the period;

          (4)  no Event of Default or Default has occurred and is continuing on
     the date of such deposit and after giving effect thereto;

          (5)  the Company delivers to the Trustee an Opinion of Counsel to the
     effect that (i) the trust resulting from the deposit does not constitute,
     or is qualified as, a regulated investment company under the Investment
     Company Act of 1940, (ii) the Holders have a valid first priority perfected
     security interest in the trust funds, and (iii) after passage of 123 days
     following the deposit (except, with respect to any trust funds for the
     account of any Holder who may be deemed to be an "insider" for purposes of
     the Bankruptcy Code, after one year following the deposit), the trust funds
     will not be subject to the effect of Section 547 of the Bankruptcy Law or
     Section 15 of the New York Debtor and Creditor Law in a case commenced by
     or against the Company under either such statute, and either (A) the trust
     funds will no longer remain the property of the Company (and therefore,
     will not be subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors' rights generally) or
     (B) if a court were to rule under any such law in any case or proceeding
     that the trust funds remained property of the Company, (x) assuming such
     trust funds remained in the possession of the Trustee prior to such court
     ruling to the extent not paid to Holders, the Trustee will hold, for the
     benefit of the Holders, a valid first priority perfected security interest
     in such trust funds that is not avoidable in bankruptcy or otherwise except
     for the effect of Section 552(b) of the Bankruptcy Law on interest on the
     trust funds accruing after the commencement of a case under such statute
     and (y) the Holders will be entitled to receive adequate protection of
     their interests in such trust funds if such trust funds are used in such
     case or proceeding;


          (6) in the case of the legal defeasance option, the Company shall have
     delivered to the Trustee an Opinion of Counsel stating that (i) the Company
     has received from, or there has been published by, the Internal Revenue
     Service a ruling, or (ii) since the date of the Indenture there has been a
     change in the applicable U.S. Federal income tax law or a regulation
     clarifying existing law, in either case to the effect that, and based
     thereon such Opinion of Counsel shall confirm that, the Holders will not
     recognize income, gain or loss for U.S. Federal income tax purposes as a
     result of such defeasance and will be subject to U.S. Federal income tax on
     the same amounts, in the same manner and at the same times as would have
     been the case if such defeasance had not occurred;

 
                                                                             104

          (7)  in the case of the covenant defeasance option, the company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders will not recognize income, gain or loss for U.S. Federal income tax
     purposes as a result of such covenant defeasance and will be subject to
     U.S. Federal income tax on the same amounts, in the same manner and at the
     same times as would have been the case if such covenant defeasance had not
     occurred;

          (8)  such defeasance or covenant defeasance shall not cause the
     Trustee to have a conflicting interest as defined in Section 9.8 and for
     purposes of the Trust Indenture Act with respect to any securities of the
     Company;

          (9)  such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute default under, any other agreement or
     instrument to which the Company is a party or by which it is bound; and

          (10) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent to the defeasance and discharge of the Securities have been
     complied with.


SECTION 14.5.  Deposited Money and U.S. Government Obligations to be held in
               -------------------------------------------------------------
               Trust; Other Miscellaneous Provisions.
               ------------------------------------- 

          Subject to the provisions of the last paragraph of Section 6.26, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee -- collectively, for purposes of
this Section 14.5 and Section 14.6, the "Trustee") pursuant to Section 14.4 in
respect of the Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Securities, of all sums due and to become due thereon in respect of
principal and interest.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 14.4 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

          Anything in this Article XIV to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 14.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance.

 
                                                                             105

          The provisions of the last paragraph of Section 6.26 shall apply to
any money held by the Trustee or any Paying Agent under this Article XIV that
remains unclaimed for two years after the Maturity Date of any Securities for
which money or Government Obligations have been deposited pursuant to Section
14.4.


SECTION 14.6.  Reinstatement.
               ------------- 

          If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 14.5 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 14.5; provided,
however, that if the Company makes any payment of principal of or interest on
any Security following the reinstatement of the Company's obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money held by the Trustee or the Paying Agent.

 
                                                                             106

                             ______________________
