                                   ARTICLE II

                                    THE BONDS

     SECTION 201. Authorized Amount of Bonds. No Bonds may be issued under the
provisions of this Indenture except in accordance with this Article. The total
principal amount of Bonds that may be issued hereunder is hereby expressly
limited to Four Million Dollars ($4,000,000).

     SECTION 202. Issuance of Bonds. The Bonds shall be designated "Taxable
Revenue Bonds (Conrad Aluminum, L.L.C. Project) Series 2003", shall be dated the
date of initial issuance and delivery thereof, and shall be issued as a single
fully registered Bond, numbered from R-1 upwards. Except as prepaid or redeemed,
the Bonds shall mature in 179 monthly principal installments of $22,222.22
commencing September 1, 2003 through and including July 1, 2018 and a final
principal installment of $22,222.62 due and payable on August 1, 2018.

     The Bonds shall bear interest from the later of the date thereof or the
most recent interest payment date to which interest has been paid or duly
provided for in full as follows:

     (a) The Lessee has previously determined that the Bonds shall initially
accrue interest at the three (3) month Libor Rate. On the last Business Day
prior to the expiration of the then applicable Interest Period for the Bonds,
Lessee will determine the Interest Period and whether the Bonds will accrue
interest at Libor Rate or Base Rate. Upon the expiration of such Interest Period
and any Interest Period thereafter, the Lessee shall have the option to convert
the interest rate accruing on all (but not less than all) of the outstanding
principal balance of the Bonds into a Libor Rate or Base Rate; provided that (i)
Bonds cannot be converted when any Default has occurred and is continuing and in
such event the Bonds shall accrue interest at the Base Rate, and (ii) no
conversions of the Bonds are allowed until the expiration of the Interest Period
applicable to the existing rate of interest has expired.

     (b) Each conversion shall be enacted by the Authorized Lessee
Representative by giving to the Bondholder at its main office prior to 11:00 a.
m. (New Orleans time) on or before the last Business Day of the applicable
Interest Period written or telephone Notice of Conversion specifying if the
Bonds are to be converted into accruing interest at Libor Rate or Base Rate and
the Interest Period to be applicable thereto. In the absence of any specific
rate election by the Lessee or if Lessee fails to provide such notice to the
Bondholder in a timely manner, the Bonds shall accrue interest at the Base Rate.

     (c) Interest on the outstanding principal owed on the Bonds shall be
computed on the basis of the actual number of days elapsed over a year composed
of 360 days.

     (d) Additionally, with respect to each Interest Period, in the event that
Bondholder shall have determined in good faith (which determination shall,
absent manifest error, be final and conclusive and binding upon all parties
hereto):

          (i) on any Interest Period or date of conversion that, by reason of
     any changes arising after the date of this Indenture affecting the London
     interbank market, adequate and fair means do not exist for ascertaining the
     applicable interest rate on the basis provided for in the definition of
     Libor Rate; or

          (ii) at any time, that Bondholder shall incur increased costs or
     reductions in the amounts received or receivable hereunder with respect to
     any Libor Rate because of any change since the date of this Indenture in
     any applicable law or governmental rule, regulation, order, guideline or
     request or in the interpretation or administration thereof and including
     the introduction of any new law or governmental rule, regulation, order,
     guideline or request, such as, for example, but not limited to: (A)

                                       -9-

<PAGE>

     a change in the basis of taxation of payment to the Bondholder of the
     principal or interest on such Libor Rate (except for changes in the rate of
     tax on, or determined by reference to, the net income or profits of the
     Bondholder) or (B) a change in official reserve requirements; or

          (iii) at any time, that the making or continuance of any Libor Rate
     has been made (x) unlawful by any law or governmental rule, regulation or
     order, (y) impossible by compliance by the Bondholder in good faith with
     any governmental request (whether or not having force of law) or (z)
     impracticable as a result of a contingency occurring after the date of this
     Indenture which materially and adversely affects the London interbank
     market;

then, and in any such event, the Bondholder shall promptly give notice (by
telephone confirmed in writing) to the Lessee. Thereafter (x) in the case of
clause (i) above, the Libor Rate shall no longer be available until such time as
the Bondholder notifies the Lessee that the circumstances giving rise to such
notice no longer exist, the Bonds shall then accrue interest at the Base Rate,
and any Notice of Conversion given by the Lessee with respect to the Libor Rate
which have not yet been incurred (including by way of conversion) shall be
deemed rescinded by the Lessee, (y) in the case of clause (ii) above, the Lessee
agrees to pay to the Bondholder, upon written demand therefor, such additional
amounts (in the form of an increased rate of, or a different method of
calculating, interest or otherwise as agreed to by the Bondholder and the
Lessee) as shall be required to compensate the Bondholder for such increased
costs or reductions in amounts received or receivable hereunder (a written
notice as to the additional amounts owed to the Bondholder, showing the basis
for the calculation thereof, submitted to the Lessee by the Bondholder in good
faith shall, absent manifest error, be final and conclusive and binding on all
the parties hereto) and (z) in the case of clause (iii) above, the Bonds shall
accrue interest at the Base Rate. The Bondholder agrees that if it gives notice
to the Lessee of any of the events described in clause (i) or (iii) above, it
shall promptly notify the Lessee if such event ceases to exist. If any such
event described in clause (iii) above ceases to exist as to the Bondholder, the
Bondholder's obligations to convert the interest accruing on the Bonds into
Libor Rate on the terms and conditions contained herein shall be reinstated.

     The Bonds are not subject to redemption prior to maturity except pursuant
to the redemption provisions of Article IV hereof.

     The principal of, premium, if any, and interest on the Bonds shall be paid
in lawful money of the United States of America, and the final payment of
principal of and interest on the Bonds shall be payable upon presentation and
surrender of such Bonds as they become due at the office of the Corporate Trust
Division of the Trustee, or its successor in trust provided that principal and
interest on each fully registered Bond shall be paid by check or draft mailed to
the registered owner thereof whose name is registered at the close of business
on the fifteenth calendar day preceding any such payment date at his or her
address as it appears on the Bond Register.

     Notwithstanding any provision of this Indenture or the Bonds to the
contrary, if a Bondholder owning all Outstanding Bonds shall file with the
Trustee an instrument requesting the amount payable by the Trustee as interest
and principal hereunder to such Bondholder or a nominee therefor be paid either
(a) by crediting in immediately available funds the amount to be distributed to
such Bondholder to any account maintained by such Bondholder with the Trustee,
or (b) by transferring by wire transfer in immediately available funds the
amount to be distributed to such Bondholder to a designated account maintained
by such Bondholder at any other bank in the United States, the Trustee shall pay
all amounts payable by the Trustee as interest and principal hereunder to such
Bondholder or nominee therefor in accordance with the provisions of any such
agreement and without presentment of such Bond to the Trustee, except for the
final maturity. Furthermore, notwithstanding any provision of this Indenture or
the Bonds to the contrary, if a Bondholder owning all Outstanding Bonds shall
file with the Trustee and the Company an instrument requesting all payments on
the Bonds to be paid directly to the Bondholder, such payments shall be paid
directly to the Bondholder without

                                      -10-

<PAGE>

any requirement for presentation and surrender as set forth in the preceding
paragraph and the Bondholder shall keep records of all payments on the Bonds on
the schedules attached to the Bonds. All payments so made shall be valid and
effective to satisfy and discharge the liability upon any Bonds, but only to the
extent of the sums actually paid and collected. Such payment shall be valid and
effective irrespective of whether any such notation has been made thereon and
irrespective of any error or omission in such notation.

     SECTION 203. Execution; Limited Obligation. The Bonds shall be executed on
behalf of the Issuer with the manual or facsimile signature of its President or
Vice President and shall have affixed, impressed, or otherwise reproduced
thereon the seal of the Issuer and attested with the manual or facsimile
signature of its Secretary-Treasurer. The Bonds, together with interest thereon,
shall be limited obligations of the Issuer payable from the Trust Estate,
including the Bond Fund, and shall be a valid claim of the respective holders
thereof only against such Trust Estate and fund and the revenues and receipts
derived from the lease or sale of the Leased Facilities and pledged to such
fund, which revenues and receipts are hereby pledged for the equal and ratable
payment of the Bonds and shall be used for no other purpose than to pay the
principal of, premium, if any, and interest on the Bonds, except as may be
otherwise expressly authorized in this Indenture or in the Lease Agreement. The
Bonds are also secured by a Guaranty Agreement. The Bonds do not now and shall
never constitute an indebtedness or a pledge of the general credit of the
Issuer, the Parish of St. Mary, the State, or any political subdivision of the
State, within the meaning of any constitutional provision or statutory
limitation of indebtedness. In case any officer whose signature or facsimile of
whose signature shall appear on the Bonds shall cease to be such officer before
the delivery of such Bonds, such signature or such facsimile shall nevertheless
be valid and sufficient for all purposes, the same as if he had remained in
office until delivery.

     SECTION 204. Authentication. Only such Bonds as shall have endorsed thereon
a certificate of authentication substantially in the form of Bond set forth in
Exhibit A duly executed by the Trustee shall be entitled to any right or benefit
under this Indenture. No Bond shall be valid or obligatory for any purpose
unless and until such certificate of authentication shall have been duly
executed by the Trustee, and such executed certificate of the Trustee upon any
such Bond shall be conclusive evidence that such Bond has been authenticated and
delivered under this Indenture. The Trustee's certificate of authentication on
any Bond shall be deemed to have been executed by it if signed by an authorized
officer of the Trustee, but it shall not be necessary that the same officer sign
the certificate of authentication on all of the Bonds issued hereunder.

     SECTION 205. Form of Bonds. The Bonds issued under this Indenture shall be
substantially in the form set forth in Exhibit A with such appropriate
variations, omissions and insertions as are permitted or required by this
Indenture.

     SECTION 206. Delivery of Bonds. Upon the execution and delivery of this
Indenture, the Issuer shall execute and deliver to the Trustee and the Trustee
shall authenticate the Bonds and deliver them to the purchasers as may be
directed by the Issuer in writing as hereinafter in this Section 206 provided.

     Prior to the delivery by the Trustee of any of the Bonds there shall be
filed with the Trustee:

          1. A copy, duly certified by the Secretary-Treasurer of the Issuer, of
     the resolution or resolutions adopted by the Board of Directors of the
     Issuer, authorizing the execution and delivery of the Lease Agreement and
     this Indenture and the issuance, execution and delivery of the Bonds.

          2. An original executed counterpart of the Lease Agreement and this
     Indenture.

          3. An original executed counterpart of the Guaranty Agreement.

          4. A request and authorization to the Trustee on behalf of the Issuer
     and signed by its President or Vice President and Secretary-Treasurer, to
     authenticate and deliver the aggregate

                                      -11-

<PAGE>

     principal amount of the Bonds to be issued to the purchasers therein
     identified upon payment to the Trustee, but for the account of the Issuer,
     of a sum specified in such request and authorization. Such proceeds shall
     be paid over to the Trustee and deposited as hereinafter provided under
     Article VII.

          5. A certified copy of the resolution of the Lessee authorizing the
     execution of the Lease Agreement and Guaranty Agreement.

          6. An opinion of Bond Counsel.

          7. Such other items, if any, required by the Purchaser under its
     commitment letter.

     Simultaneously with the delivery of the Bonds, the Trustee shall apply the
proceeds of the Bonds (including accrued interest, if any) in accordance with
Article VII hereof.

     SECTION 207. Mutilated, Lost, Stolen or Destroyed Bonds. In the event any
Bond is mutilated, lost, stolen or destroyed, the Issuer may execute and the
Trustee may authenticate a new Bond of like date, maturity and denomination as
the Bond mutilated, lost, stolen or destroyed; provided that, in the case of any
mutilated Bonds, such mutilated Bond shall first be surrendered to Trustee, and
in the case of any lost, stolen or destroyed Bond, there shall be first
furnished to the Issuer and the Trustee evidence of such loss, theft or
destruction satisfactory to the Issuer and the Trustee, together with indemnity
satisfactory to them. In the event any such Bond shall have matured, instead of
issuing a substitute Bond the Issuer may pay the same without surrender thereof.
The Issuer and the Trustee may charge the holder or owner of such Bond with
their reasonable fees and expenses in this connection. Each new Bond shall in
all respects be identical with the pertinent lost, mutilated, destroyed or
stolen Bond, except that it shall bear on its face the following clause:

     "This bond is issued to replace a lost, cancelled or destroyed Bond under
     the authority of R.S. 39:971 through 39:974."

     SECTION 208. Registration of Bonds; Persons Treated as Owners. So long as
any of the Bonds shall remain outstanding, the Issuer shall maintain and keep,
at the office of the Corporate Trust Division of the Trustee, books for the
registration and transfer of Bonds (the "Bond Register"), and the Issuer shall
register or cause to be registered therein, under such reasonable regulations as
it or the Trustee may prescribe, any Bond. So long as any of the Bonds remain
outstanding, the Issuer shall make all necessary provisions to permit the
exchange of Bonds at such office of the Trustee.

     All Bonds shall be transferable only on the Bond Register upon surrender of
such Bond at the office of the Corporate Trust Division of the Trustee, with a
written instrument of transfer satisfactory to the Trustee duly executed by the
registered owner or his attorney duly authorized in writing.

     Bonds, upon surrender thereof at the office of the Corporate Trust Division
of the Trustee with a written instrument of transfer satisfactory to the Trustee
duly executed by the Registered Owner or his attorney duly authorized in
writing, may at the option of the Registered Owner thereof be exchanged for an
equal aggregate principal amount of Bonds of the same maturity and interest rate
in any of the authorized denominations and registered in such name or names as
may be requested.

     Registrations and transfers of Bonds shall be without charge to the holder
of the Bonds but, for every registration or transfer of Bonds, the Issuer or the
Trustee may make a charge sufficient to reimburse it for any tax, fee or other
governmental charge required to be paid with respect to such registration or
transfer, which sum or sums shall be paid by the person requesting such
registration or transfer as a condition precedent to the exercise of the
privilege of making such registration or transfer.

                                      -12-

<PAGE>

     Each Bond delivered pursuant to any provision of this Indenture in exchange
or substitution for, or upon the transfer of the whole or any part of one or
more other Bonds, shall carry all of the rights to interest accrued and unpaid
and to accrue which were carried by the whole or such part, as the case may be,
of such one or more other Bonds, and notwithstanding anything contained in this
Indenture, such Bonds shall be so dated or bear such notation that neither gain
or loss in interest shall result from any such exchange, substitution or
transfer.

     Every transfer of Bonds under the foregoing provisions shall be effected in
such manner as may be prescribed by the Issuer or pursuant to its written
authorization, with the approval of the Trustee. Neither the Issuer nor the
Trustee shall be required (a) to register or transfer Bonds for a period of ten
days next preceding an interest payment date on the Bonds or next preceding the
date of first publication or mailing of notice of redemption, whichever is
earlier, or (b) to register or transfer any Bonds called for redemption.

     Anything in this Indenture to the contrary notwithstanding, there shall not
be effected, and the Trustee, acting as bond registrar, shall not permit the
effecting of, any transfer of any Bond pursuant to the provisions of this
Section, unless there is delivered to the Trustee an opinion of counsel
satisfactory to the Trustee and the Lessee to the effect that such transfer will
not violate applicable securities laws.

                               REVENUES AND FUNDS

     SECTION 601. Creation of Bond Fund. There is hereby created by the Issuer
and ordered established with the Trustee a trust fund to be designated "Taxable
Revenue Bond Fund -- Conrad Aluminum, L.L.C. Project" (the "Bond Fund").

     Moneys on deposit in the Bond Fund shall be used to pay the principal of
and interest and premium, if any, on the Bonds as the same mature and become due
or upon the redemption thereof prior to maturity except as provided in Sections
602, 609, 1107 and 1202 hereof.

     SECTION 602. Payments into the Bond Fund. There shall be deposited in the
Bond Fund the amounts required by Section 701 hereof. Additionally, there shall
be deposited in the Bond Fund, as and when received, (a) all rental payments
specified in Section 4.3(a) of the Lease Agreement; provided, however, that in
the event a Bondholder files an election to be paid directly in accordance with
the provisions of Section 202(d) hereof, said rental payments shall be paid
directly to the Bondholder, and references to deposits into the Bond Fund shall
be of no force and effect; (b) all payments made pursuant to the Guaranty
Agreement; and (c) all other moneys received by the Trustee under and pursuant
to any of the provisions of the Lease Agreement when accompanied by written
directions from the Lessee that such moneys are to be paid into the Bond Fund or
otherwise received on account of the Leased Facilities. The Issuer hereby
covenants and agrees that so long as any of the Bonds issued hereunder are
outstanding it will deposit, or cause to be deposited, in the Bond Fund for its
account sufficient sums from revenues and receipts derived from the Leased
Facilities (whether or not under and pursuant to the Lease Agreement) promptly
to meet and pay the principal of and interest and premium, if any, on the Bonds
as the same become due and payable and to this end the Issuer covenants and
agrees that, so long as any Bonds issued hereunder are outstanding, should there
be a default under the Lease Agreement with the result that the right of
possession of the Leased Facilities under the Lease Agreement is returned to the
Issuer, the Issuer shall fully cooperate with the Trustee and with the
Bondholders to the end of fully protecting the rights and security of the
Bondholders and shall diligently proceed in good faith and use its best efforts
to secure another lessee or a suitable tenant for the Leased Facilities to the
end that at all times sufficient revenues and receipts will be derived from the
Leased Facilities promptly to meet and pay the principal of and interest and
premium, if any, on the Bonds as the same become due and payable, as well as
covering the cost of maintaining and insuring the Leased Facilities as more
particularly provided in the Lease Agreement. Nothing herein shall be construed
as requiring the Issuer to operate the Leased Facilities or to use any funds or
revenues from any source other than funds and revenues derived from the Leased
Facilities.

     SECTION 603. Use of Moneys in the Bond Fund. Except as provided in Sections
602, 609, 1107 and 1202 hereof, moneys in the Bond Fund shall be used solely for
the payment of the premium, if any, and the interest on the Bonds and for the
payment or redemption of the principal of the Bonds.

     Whenever the amount in the Bond Fund from any source whatsoever is
sufficient to redeem all of the outstanding Bonds and to pay interest to accrue
thereon to such redemption, the Issuer covenants and agrees, upon request of the
Lessee, to take and cause to be taken the necessary steps to redeem all such
Bonds on the next succeeding redemption date for which the required redemption
notice may be given or on such later redemption date as may be specified by the
Lessee.

     SECTION 604. Custody of Bond Fund. The Bond Fund shall be in the custody of
the Trustee but in the name of the Issuer, and the Issuer hereby authorizes and
directs the Trustee to withdraw sufficient funds from the Bond Fund to pay the
principal of, and premium, if any, and interest on the Bonds, as the same may
become due and payable, and to make said funds so withdrawn available to the
Trustee for the purpose of

                                      -19-

<PAGE>

paying said principal and interest and premium, if any, which authorization and
direction the Trustee hereby accepts.

     SECTION 605. Non-presentment of Bonds. In the event any Bonds shall not be
presented for payment when the principal thereof becomes due, either at maturity
or otherwise, or at the date fixed for redemption thereof, if funds sufficient
to pay such Bonds shall be held by the Trustee for the benefit of the owner or
owners thereof, all liability of the Issuer to the owner thereof for the payment
of such Bond shall forthwith cease, determine and be completely discharged, and
thereupon it shall be the duty of the Trustee to hold such fund or funds without
liability for interest thereon, for the benefit of the owner of such Bond, who
shall thereafter be restricted exclusively to such fund or funds, for any claim
of whatever nature on his part under this Indenture or on, or with respect to,
said Bond.

     SECTION 606. Trustee's Fees, Charges and Expenses. Pursuant to the
provisions of the Lease Agreement, the Lessee has agreed to pay to the Trustee,
at the commencement of the Lease Term (as defined in the Lease Agreement) and
continuing until the principal of and interest and premium, if any, on the Bonds
shall have been fully paid or provision for the payment thereof shall have been
made in accordance with the provisions of this Indenture: (i) an amount equal to
the annual fee of the Trustee for the Ordinary Services of the Trustee rendered
and its Ordinary Expenses incurred under this Indenture, (ii) the reasonable
fees and charges of the Trustee, as bond registrar and paying agent, and (iii)
the reasonable fees and charges of the Trustee, including reasonable attorney
fees and expenses, for Extraordinary Services and Extraordinary Expenses of the
Trustee under this Indenture, as and when the same become due. The Lessee may,
without creating a default hereunder, contest in good faith the necessity for
any such Extraordinary Services and Extraordinary Expenses and the
reasonableness of any of the fees or charges referred to herein.

     SECTION 607. Moneys to be Held in Trust. All moneys required to be
deposited with or paid to the Trustee for account of the Bond Fund under any
provision of this Indenture shall be held by the Trustee in trust, and except
for moneys deposited with or paid to the Trustee for the redemption of Bonds,
notice of the redemption of which has been duly given, shall, while held by the
Trustee, constitute part of the Trust Estate and be subject to the lien hereof.

     SECTION 608. Insurance and Condemnation Proceeds. Reference is hereby made
to Articles V and VI of the Lease Agreement for the provisions governing
insurance and condemnation proceeds.

     SECTION 609. Repayment to the Lessee from the Bond Fund. Any amounts
remaining in the Bond Fund after payment in full of the principal and interest
and premium, if any, on the Bonds (or provision for the payment thereof as
provided in this Indenture) and all fees, charges and expenses of the Trustee
and all other amounts required to be paid hereunder, shall be paid to the Lessee
upon the expiration or sooner termination of the term of the Lease Agreement as
provided in Section 11.6 of the Lease Agreement.

     SECTION 610. Deposits under Guaranty Agreement. Reference is hereby made to
the Guaranty Agreement, wherein it is provided that the Guarantors guarantee the
prompt and full payment of the principal of, premium, if any, and interest on,
the Bonds. The Trustee and the Issuer hereby acknowledge that any amounts paid
under the Guaranty Agreement shall be paid directly to the Trustee and deposited
in the Bond Fund. All amounts received under the Guaranty Agreement shall be
applied solely to the payment of the principal of, premium, if any, and interest
on the Bonds or returned to the Guarantors.

     SECTION 801. Investment of Moneys. Any moneys held by the Trustee in any
fund or account under this Indenture shall be separately invested and reinvested
by the Trustee in Eligible Investments at the written direction of the Lessee.

     The Trustee may make any and all investments of funds through its own bond
department, or in the investment department of any Bondholder. The Trustee is
authorized and directed to cause to be sold and reduce to cash a sufficient
amount of Eligible Investments whenever the cash balance is or will be
insufficient to make a requested or required disbursement. The Trustee shall not
be accountable for any depreciation in value of the Eligible Investments or for
any loss resulting from such sale. The Trustee shall have no liability for any
investments made in accordance with this Section 801.

     Notwithstanding the foregoing, to the extent any funds or accounts are held
by or transferred to the Bondholder, such funds or accounts shall be invested by
the Bondholder in Eligible Investments at the written direction of the Lessee
and the Trustee will have no responsibility with respect thereto.

     Lessee by the Trustee or to the Trustee and the Issuer by the holders of
     not less than twenty-five percent (25%) in aggregate principal amount of
     Bonds then outstanding, unless the Lessor and the Trustee (with any
     required consent of the Bondholders pursuant to Section 1111 hereof) shall
     agree in writing to an extension of such time prior to its expiration; or

          (d) The occurrence, of an "event of default" under the Lease Agreement

delivered to the Issuer and the Lessee, declare the principal of all Bonds then
outstanding and the interest accrued thereon immediately due and payable, and
such principal and interest shall thereupon become and be immediately due and

immediately exercise such rights as it may have to declare all rental payments
payable under Section 4.3 of the Lease Agreement to be immediately due and
payable in accordance with Section 9.2(a) of the Lease Agreement.

     SECTION 1103. Surrender of Possession of Leased Facilities; Rights and

the Trustee, by such officer or agent as it may appoint, to take possession of,
all or any part of the Leased Facilities together with the books, papers and
accounts of the Issuer pertaining thereto, and including the rights and the

the same, and from time to time make all needful repairs and improvements as by

the moneys so received in accordance with the provisions of Section 1107 hereof.
Whenever all that is due upon the Bonds shall have been paid and all defaults
made good, the Trustee shall surrender possession to the Issuer, its successors
or assigns; the same right of entry, however, to exist upon any subsequent event
of default.

     While in possession of such property the Trustee shall render annually to
the Issuer and the Lessee and also to the Bondholders, at their addresses set
forth in the Bond Register, a summarized statement of income and expenditures in
connection therewith.

     Upon the occurrence of an event of default hereunder, to the extent that
such rights may then lawfully be waived, neither the Issuer, nor anyone claiming
through or under it, shall set up, claim, or seek to take advantage of any

force, in order to prevent or hinder the enforcement of this Indenture, and the
Issuer, for itself and all who may claim through or under it, hereby waives, to
the extent that it lawfully may do so, the benefit of all such laws and all
right of appraisement and redemption to which it may be entitled under the laws
of Louisiana.

     SECTION 1104. Other Remedies; Rights of Bondholders. Upon the occurrence of
an event of default the Trustee may, as an alternative, either after entry or
without entry, pursue any available remedy by action at law or suit in equity to
enforce the payment of the principal of, premium, if any, and interest on the
Bonds then outstanding.

     If an event of default shall have occurred, and if requested so to do by
the holders of a majority in aggregate principal amount of Bonds then
outstanding and indemnified as provided in subsection (m) of Section 1201
hereof, the Trustee shall be obliged to exercise such of the rights and powers
conferred by this Section and by Section 1103 hereof as the Trustee, being
advised by counsel, shall deem most expedient in the interest of the
Bondholders.

     No remedy by the terms of this Indenture conferred upon or reserved to the
Trustee (or to the Bondholders) is intended to be exclusive of any other remedy,
but each and every such remedy shall be cumulative and shall be in addition to
any other remedy given to the Trustee or to the Bondholders hereunder or now or
hereafter existing at law or in equity or by statute.

     No delay or omission to exercise any right or power accruing upon any
default or event of default shall impair any such right or power or shall be
construed to be a waiver of any such default or event of default or acquiescence
therein; and every such right and power may be exercised from time to time and
as often as may be deemed expedient.

     No waiver of any default or event of default hereunder, whether by the
Trustee pursuant to the provisions of Section 1111 hereof, or by the
Bondholders, shall extend to or shall affect any subsequent default or event of
default or shall impair any rights or remedies consequent thereon.

     SECTION 1105. Right of Bondholders to Direct Proceedings. Anything in this
Indenture to the contrary notwithstanding, the holders of a majority of the
aggregate principal amount of Bonds then outstanding shall have the right, at
any time, by an instrument or instruments in writing executed and delivered to
the Trustee, to direct the time, method and place of conducting all proceedings
to be taken in connection with the enforcement of the terms and conditions of
this Indenture, or for the appointment of a receiver or any other proceedings
hereunder; provided, that such direction shall not be otherwise than in
accordance with the provisions of law and of this Indenture.

                                      -27-

     SECTION 1106. Appointment of Receivers. Upon the occurrence of an event of
default hereunder, and upon the filing of a suit or other commencement of
judicial proceedings to enforce the rights of the Trustee and of the Bondholders
under this Indenture, the Trustee shall be entitled, as a matter of right, to
the appointment of a receiver or receivers of the Leased Facilities and of the
rents, revenues, issues, earnings, income, products and profits thereof, pending
such proceedings, with such powers as the court making such appointment shall
confer.

     SECTION 1107. Application of Moneys. All moneys received by the Trustee
with respect to the Leased Facilities pursuant to any right given or action
taken under the provisions of this Article shall, after payment of the costs and
expenses of the proceedings resulting in the collection of such moneys and of
the expenses, liabilities and advances incurred or made by the Trustee, be
deposited in the Bond Fund, and all moneys so deposited in the Bond Fund and all
moneys held or deposited in the Bond Fund during the continuance of an event of
default hereunder and available for payment of the Bonds under the provisions of
Section 603 hereof shall (after payment of all fees and expenses of the Trustee)
be applied as follows:

          (a) Unless the principal of all Bonds shall have become or shall have
     been declared due and payable, all such moneys shall be applied:

               First--To the payment to the persons entitled thereto of all
          installments of interest then due on the Bonds, in the order of the
          maturity of the installments of such interest and, if the amount
          available shall not be sufficient to pay in full any particular
          installment, then to the payment ratably, according to the amounts due
          on such installment, to the persons entitled thereto, without any
          discrimination or privilege; and

               Second--To the payment to the persons entitled thereto of the
          unpaid principal of any of the Bonds which shall have become due
          (other than Bonds called for redemption the payment of which moneys
          are held pursuant to the provisions of this Indenture), in the order
          of their due dates, with interest on such Bonds from the respective
          dates upon which they become due and, if the amount available shall
          not be sufficient to pay in full Bonds due on any particular date,
          together with such interest, then to the payment ratably, according to
          the amount of principal due on such date, to the persons entitled
          thereto without any discrimination or privilege.

          (b) If the principal of all the Bonds shall have become due or shall
     have been declared due and payable, all such moneys shall be applied to the
     payment of the principal and interest then due and unpaid upon all of the
     Bonds, without preference or priority of principal over interest or of
     interest over principal, or of any installment of interest over any other
     installment of interest, or of any Bond over any other Bond, ratably,
     according to the amount due respectively for principal and interest, to the
     persons entitled thereto without any discrimination or privilege.

          (c) If the principal of all the Bonds shall have been declared due and
     payable, and if such declaration shall thereafter have been rescinded and
     annulled under the provisions of this Article then, subject to the
     provisions of paragraph (b) of this Section in the event that the principal
     of all the Bonds shall later become due or be declared due and payable, the
     moneys shall be applied in accordance with the provisions of paragraph (a)
     of this Section.

     Whenever moneys are to be applied pursuant to the provisions of this
Section, such monies shall be applied at such times, and from time to time, as
the Trustee shall determine, having due regard to the amount of such moneys
available for application and the likelihood of additional monies becoming
available for such application in the future. Whenever the Trustee shall apply
such funds, it shall fix the date (which shall be an interest payment date
unless it shall deem another date more suitable) upon which such application is
to be

                                      -28-

<PAGE>

made and upon such date interest on the amounts of principal to be paid on such
dates shall cease to accrue. The Trustee shall give such notice as it may deem
appropriate of the deposit with it of any such moneys and of the fixing of any
such date, and shall not be required to make payment to the holder of any Bond
until such Bond shall be presented to the Trustee for appropriate endorsement or
for cancellation if fully paid.

     Whenever all of the Bonds and interest thereon have been paid under the
provisions of this Section 1107 and all fees, charges and expenses of the
Trustee and all other amounts required to be paid hereunder have been paid, any
balance remaining in the Bond Fund shall be paid to the Lessee as provided in
Section 609 hereof.

     SECTION 1108. Remedies Vested in Trustee. All rights of action (including
the right to file proof of claims) under this Indenture or under any of the
Bonds may be enforced by the Trustee without the possession of any of the Bonds
or the production thereof in any trial or other proceedings relating thereto and
any such suit or proceeding instituted by the Trustee shall be brought in its
name as Trustee without the necessity of joining as plaintiffs or defendants any
holders of the Bonds, and any recovery or judgment shall, subject to the
provisions of Section 1107 hereof, be for the equal benefit of the holders of
the outstanding Bonds.

     SECTION 1109. Rights and Remedies of Bondholders. No holder of any Bond
shall have any right to institute any suit, action or proceeding in equity or at
law for the enforcement of this Indenture or for the execution of any trust
thereof or for the appointment of a receiver or any other remedy hereunder,
unless a default has occurred of which the Trustee has been notified as provided
in subsection (h) of Section 1201, or of which by said subsection it is deemed
to have notice, nor unless also such default shall have become an event of
default hereunder and the holders of twenty-five percent (25%) in aggregate
principal amount of Bonds then outstanding shall have made written request to
the Trustee and shall have offered it reasonable opportunity either to proceed
to exercise the powers hereinbefore granted or to institute such action, suit or
proceeding in its own name, nor unless also they have offered to the Trustee
indemnity as provided in Section 1201 nor unless the Trustee shall thereafter
fail or refuse to exercise the powers hereinbefore granted, or to institute such
action, suit or proceeding in its, his or their own name or names; and such
notification, request and offer of indemnity are hereby declared in every case
at the option of the Trustee to be conditions precedent to the execution of the
powers and trusts of this Indenture, and to any action or cause of action for
the enforcement of this Indenture, or for the appointment of a receiver or for
any other remedy hereunder; it being understood and intended that no one or more
holders of the Bonds shall have any right in any manner whatsoever to affect,
disturb or prejudice the lien of this Indenture by its, his or their action or
to enforce any right hereunder except in the manner herein provided and that all
proceedings at law or in equity shall be instituted, had and maintained in the
manner herein provided and for the equal benefit of the holders of all Bonds
then outstanding. Nothing in this Indenture contained shall, however, affect or
impair the right of any Bondholder to enforce the payment of the principal of
and interest on any Bond at and after the maturity thereof, or the obligation of
the Issuer to pay the principal of and interest and premium, if any, on each of
the Bonds issued hereunder to the respective holders thereof at the time, place,
from the source and in the manner stated herein and in said Bonds.

     SECTION 1110. Termination of Proceedings. In case the Trustee shall have
proceeded to enforce any right under this Indenture by the appointment of a
receiver, by entry or otherwise, and such proceedings shall have been
discontinued or abandoned for any reason, or shall have been determined
adversely, then and in every such case the Issuer, the Lessee and the Trustee
shall be restored to their former positions and rights hereunder, and all
rights, remedies and powers of the Trustee shall continue as if no such
proceeding had been taken.

     SECTION 1111. Waivers of Events of Default. The Trustee shall waive any
event of default hereunder and its consequences and rescind any declaration of
maturity of principal of and interest on the Bonds upon the written request of
the holders of (1) a majority in aggregate principal amount of all the Bonds

                                      -29-

<PAGE>

then outstanding in respect of which default in the payment of principal and/or
interest exists, or (2) a majority in aggregate principal amount of all Bonds
then outstanding in the case of any other default; provided, however, that there
shall not be waived without the consent of the holders of all the Bonds
outstanding (a) any event of default in the payment of the principal of any
outstanding Bonds at the date of maturity specified therein or (b) any default
in the payment when due of the interest on any such Bonds unless, prior to such
waiver or rescission, all arrears of interest, with interest (to the extent
permitted by law) on overdue of installments of interest at the Base Rate, in
respect of which such default shall have occurred, or all arrears of payments of
principal when due, as the case may be, and all expenses of the Trustee in
connection with such default shall have been paid or provided for, and in case
of any such waiver or rescission, or in case any proceeding taken by the Trustee
on account of any such default shall have been discontinued or abandoned or
determined adversely, then and in every such case the Issuer, the Trustee and
the Bondholders shall be restored to their former positions and rights hereunder
respectively, but no such waiver or rescission shall extend to any subsequent or
other default, or impair any right consequent thereon.

     SECTION 1112. Notice of Defaults; Opportunity of Lessee to Cure Defaults.
Anything herein to the contrary notwithstanding, no default specified in Section
1101(c) hereof on the part of the Issuer or the Lessee shall constitute an event
of default hereunder until actual notice of such default by registered or
certified mail shall be given by the Trustee or by the holders of not less than
twenty-five percent (25%) in aggregate principal amount of all the Bonds then
outstanding to the Issuer and to the Lessee, and the Issuer and the Lessee shall
have had sixty (60) days after receipt of such notice to correct said default or
cause said default to be corrected, and shall not have corrected said default or
caused said default to be corrected within such period; provided, however, if
any default specified in Section 1101(c) shall be such that it cannot be
corrected within such period, it shall not constitute an event of default
hereunder if corrective action is instituted by the Lessee within the applicable
period and diligently pursued until the default is corrected; and provided
further if any default specified in Section 1101(c) should occur by reason of
the failure of the Lessee to perform any covenant, condition or agreement on its
part contained in the Lease Agreement which failure would not constitute an
event of default under Section 9.1 of the Lease Agreement by reason of force
majeure as defined therein, then such default shall not constitute an event of
default under Section 1101(c) hereof.

     With regard to an alleged default concerning which notice is given to the
Lessee under the provisions of this Section 1112, the Issuer hereby grants the
Lessee full authority for the account of the Issuer to perform any covenant or
obligation the non-performance of which is alleged in said notice to constitute
a default in the name and stead of the Issuer with full power to do any and all
things and acts to the same extent that the Issuer could do and perform any such
things and acts and with power of substitution.

                                   ARTICLE XII

                                   THE TRUSTEE

     SECTION 1201. Acceptance of Trusts. The Trustee hereby accepts the trusts
imposed upon it by this Indenture, and agrees to perform said trusts, but only
upon and subject to the following express terms and conditions, and no implied
covenants or obligations shall be read into this Indenture against the Trustee:

          (a) The Trustee, prior to the occurrence of an event of default
     hereunder and after the curing of all events of default which may have
     occurred hereunder, undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture. In case an event of
     default has occurred hereunder (which has not been cured) 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 their exercise, as a prudent
     trustee would exercise or use under the circumstances in the conduct of its
     corporate trust duties.

          (b) The Trustee may execute any of the trusts or powers hereof and
     perform any of its duties by or through attorneys, agents, receivers or
     employees but shall be answerable for the conduct of the same in accordance
     with the standard specified above, and shall be entitled to act upon the
     opinion or advice of its counsel concerning all matters of trust hereof and
     the duties hereunder, and may in all cases pay such reasonable compensation
     to all such attorneys, agents, receivers and employees as may reasonably be
     employed in connection with the trust hereof. The Trustee may act upon an
     Opinion of Counsel and shall not be responsible for any loss or damage
     resulting from any action or non-action by it taken or omitted to be taken
     in good faith in reliance upon such Opinion of Counsel.

          (c) The Trustee shall not be responsible for any recital herein or in
     the Bonds (except in respect to the certificate of the Trustee endorsed on
     the Bonds), or for the recording or re-recording, filing or refiling of
     this Indenture or for insuring the Leased Facilities or collecting any
     insurance moneys, or for the validity of the execution by the Issuer of
     this Indenture or of any supplements hereto or instruments of further
     assurance, or for the sufficiency of the security for the Bonds issued
     hereunder or intended to be secured hereby, or otherwise as to the
     maintenance of the security hereof, and the Trustee shall not be bound to
     ascertain or inquire as to the performance or observance of any covenants,
     conditions or agreements on the part of the Issuer or on the part of the
     Lessee in connection with the matters referred to in Sections 503 and 504
     hereof, except as hereinafter set forth; but the Trustee may require of the
     Issuer or the Lessee full information and advice as to the performance of
     the covenants, conditions and agreements aforesaid as to the condition of
     the Leased Facilities. Except as otherwise provided in Section 1103 hereof,
     the Trustee shall have no obligation to perform any of the duties of the
     Issuer as lessor under the Lease Agreement; and the Trustee shall not be
     responsible or liable for any loss suffered in connection with any
     investment of funds made by it in accordance with Section 801.

          (d) The Trustee shall not be liable for the use of any Bonds
     authenticated or delivered hereunder. The Trustee may become the owner of
     Bonds secured hereby with the same rights which it would have if not
     Trustee.

          (e) The Trustee shall be protected in acting upon any notice, request,
     consent, certificate, order, affidavit, letter, telegram or other paper or
     document believed by it to be genuine and correct and action taken by the
     Trustee pursuant to this Indenture upon the request or authority or consent
     of any person who at the time of making such request or giving such
     authority or consent is the owner of any Bond, shall be conclusive and
     binding upon all future owners of the same Bond and upon Bonds issued in
     exchange therefor or in place thereof.

                                      -31-

<PAGE>

          (f) As to the existence or non-existence of any fact or as to the
     sufficiency or validity of any instrument, paper or proceeding, the Trustee
     shall be entitled to rely upon a certificate signed on behalf of the Issuer
     by its President or Vice President or such other person as may be
     designated for such purpose by resolution of the Board of Directors of the
     Issuer, the governing authority of the Issuer, and attested by its
     Secretary-Treasurer or such other person as may be designated for such
     purpose by resolution of the Issuer as sufficient evidence of the facts
     therein contained and prior to the occurrence of a default of which the
     Trustee has been notified as provided in subsection (h) of this Section, or
     of which pursuant to said subsection it is deemed to have notice, shall
     also be at liberty to accept a similar certificate to the effect that any
     particular dealing, transaction or action is necessary or expedient, but
     may at its discretion secure such further evidence as it deems necessary or
     advisable, but shall in no case be bound to secure the same. The Trustee
     may accept a certificate of the Secretary-Treasurer of the Issuer under the
     seal of the Issuer to the effect that a resolution in the form therein set
     forth has been adopted by the Issuer as conclusive evidence that such
     resolution has been duly adopted, and is in full force and effect.

          (g) The permissive right of the Trustee to do things enumerated in
     this Indenture shall not be construed as a duty and the Trustee shall not
     be answerable for other than its negligence or wilful misconduct.

          (h) The Trustee shall not be required to take notice or be deemed to
     have notice of any default hereunder except any default under paragraphs
     (a) or (b) of Section 1101 unless the Trustee shall be specifically
     notified in writing of such default by the Issuer or by the holders of at
     least twenty-five percent (25%) in aggregate principal amount of Bonds then
     outstanding and all notices or other instruments required by this Indenture
     to be delivered to the Trustee must, in order to be effective, be delivered
     at the principal office of the Trustee, and in the absence of such notice
     so delivered the Trustee may conclusively assume there is no default except
     as aforesaid.

          (i) The Trustee shall not be personally liable for any debts
     contracted or for damages to persons or to personal property injured or
     damaged or for salaries or non-fulfillment of contracts during any period
     in which it may be in the possession of or managing the Leased Facilities
     as in this Indenture provided.

          (j) At any and all reasonable times the Trustee, and its duly
     authorized agents, attorneys, experts, engineers, accountants and
     representatives, shall have the right, but shall not be required, to
     inspect any and all books, papers and records of the Issuer pertaining to
     the Leased Facilities and the Bonds, and to take such memoranda from and in
     regard thereto as may be desired.

          (k) The Trustee shall not be required to give any bond or surety in
     respect to the execution of the said trusts and powers or otherwise in
     respect of the premises.

          (l) Notwithstanding anything elsewhere in this Indenture contained,
     the Trustee shall have the right, but shall not be required, to demand, in
     respect of the authentication of any Bonds, the withdrawal of any cash, the
     release of any property, or any action whatsoever within the purview of
     this Indenture, any showings, certificates, opinions, appraisals or other
     information, or corporate action or evidence thereof, in addition to that
     by the terms hereof required, as a condition of such action by the Trustee
     deemed desirable for the purpose of establishing the right of the Issuer to
     the authentication of any Bonds, the withdrawal of any cash, or the taking
     of any other action by the Trustee.

          (m) Before taking any action under this Section 1201 or Article XI of
     this Indenture, the Trustee may require that satisfactory indemnity be
     furnished to it for the reimbursement of all

                                      -32-

<PAGE>

     expenses to which it may be put and to protect it against all liability,
     except liability which is adjudicated to have resulted from its negligence
     or wilful misconduct, by reason of any action so taken.

          (n) All moneys received by the Trustee or any paying agent shall,
     until used or applied or invested as herein provided, be held in trust in
     the manner and for the purposes for which they were received but need not
     be segregated from other funds except to the extent required by this
     Indenture or law. Neither the Trustee nor any paying agent shall be under
     any liability for interest on any moneys received hereunder except such as
     may be agreed upon in writing.

     SECTION 1202. Fees, Charges and Expenses of Trustee. The Trustee shall be
entitled to payment and/or reimbursement for reasonable fees for its Ordinary
Services rendered hereunder and all advances, counsel fees and other Ordinary
Expenses reasonably and necessarily made or incurred by the Trustee in
connection with such Ordinary Services and, in the event that it should become
necessary that the Trustee perform Extraordinary Services, it shall be entitled
to reasonable extra compensation therefor, and to reimbursement for reasonable
and necessary Extraordinary Expenses in connection therewith; provided, that if
such Extraordinary Services or Extraordinary Expenses are occasioned by the
gross negligence or wilful misconduct of the Trustee, it shall not be entitled
to compensation or reimbursement therefor. The Trustee shall be entitled to
payment and reimbursement for the reasonable fees and charges of the Trustee as
paying agent and registrar for the Bonds as hereinabove provided. Upon the
occurrence of an event of default hereunder, but only upon such occurrence, the
Trustee shall have a first lien with right of payment prior to payment on
account of interest or principal of any Bond, from the moneys received by it for
the foregoing advances, fees, costs and expenses incurred.

     SECTION 1203. Notice to Bondholders if Default Occurs. If a default occurs
of which the Trustee is by subsection (h) of Section 1201 hereof required to
take notice or if notice of default be given as in said subsection (h) provided,
then within five (5) business days of obtaining knowledge of such default, the
Trustee shall give written notice thereof by first class mail to the owners of
all Bonds then outstanding shown by the Bond Register.

     SECTION 1204. Intervention by Trustee. In any judicial proceeding to which
the Issuer is a party and which in the opinion of the Trustee and its counsel
has a substantial bearing on the interests of owners of the Bonds, the Trustee
may intervene on behalf of Bondholders and shall do so if requested in writing
by the owners of at least twenty-five percent (25%) in aggregate principal
amount of all Bonds then outstanding, provided that the Trustee shall first have
been offered such reasonable indemnity as it may require against the costs,
expenses and liabilities which it may incur in or by reason of such proceeding.
The rights and obligations of the Trustee under this Section are subject to the
approval of a court of competent jurisdiction.

     SECTION 1205. Successor Trustee. Any corporation or association into which
the Trustee may be converted or merged, or with which it may be consolidated, or
to which it may sell or transfer its trust business and assets as a whole or
substantially as a whole, or any corporation or association resulting from any
such conversion, sale, merger, consolidation or transfer to which it is a party,
ipso facto, shall be and become successor Trustee hereunder and vested with all
of the title to the whole property or trust estate and all the trusts, powers,
discretions, immunities, privileges and all other matters as was its
predecessor, without the execution or filing of any instrument or any further
act, deed or conveyance on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

     SECTION 1206. Resignation by the Trustee. The Trustee and any successor
Trustee may at any time resign from the trusts hereby created by giving thirty
(30) days' written notice to the Issuer and the Lessee and by first class mail
to each registered owner of Bonds as shown by the Bond Register, and such
resignation shall

                                      -33-

<PAGE>

take effect upon the appointment of a successor Trustee by the Bondholders or by
the Issuer. Such notice to the Issuer and to the Lessee may be served personally
or sent by registered mail.

     SECTION 1207. Removal of the Trustee. The Trustee may be removed at any
time, by an instrument or concurrent instruments in writing delivered to the
Trustee and to the Issuer, and signed by the owners of a majority in aggregate
principal amount of Bonds then outstanding.

     SECTION 1208. Appointment of Successor Trustee by the Bondholders;
Temporary Trustee. In case the Trustee hereunder shall resign or be removed, or
be dissolved, or shall be in course of dissolution or liquidation, or otherwise
become incapable of acting hereunder, or in case it shall be taken under the
control of any public officer or officers or of a receiver appointed by a court,
a successor may be appointed by the owners of a majority in aggregate principal
amount of Bonds then outstanding, by an instrument or concurrent instruments in
writing signed by such owners, or by their attorneys-in-fact, duly authorized;
provided, nevertheless, that in case of such vacancy the Issuer by an instrument
executed and signed by its President and attested by its Secretary-Treasurer
under its seal, may appoint a temporary Trustee to fill such vacancy until a
successor Trustee shall be appointed by the Bondholders in the manner above
provided; and any such temporary Trustee so appointed by the Issuer shall
immediately and without further act be superseded by the Trustee so appointed by
such Bondholders. Every such Trustee appointed pursuant to the provisions of
this Section shall be a trust company or bank in good standing within the State
having a reported capital and surplus of not less than twenty-five million
dollars, if there be such an institution willing, qualified and able to accept
the trust upon reasonable or customary terms. So long as there does not exist
any event of default under the Lease Agreement, the appointment of any successor
Trustee pursuant to the provisions of this Section shall be subject to the
approval of the Lessee, which approval shall not be unreasonably withheld.

     SECTION 1209. Concerning Any Successor Trustees. Every successor Trustee
appointed hereunder shall execute, acknowledge and deliver to its predecessor
and also to the Issuer and the Lessee an instrument in writing accepting such
appointment hereunder, and thereupon such successor, without any further act,
deed or conveyance, shall become fully vested with all the estates, properties,
rights, powers, trusts, duties and obligations of its predecessors; but such
predecessor shall, nevertheless, on the written request of the Issuer, or of its
successor, execute and deliver an instrument transferring to such successor
Trustee all the estates, properties, rights, powers, and trusts of such
predecessor hereunder; and every predecessor Trustee shall deliver all
securities and moneys held by it as Trustee hereunder to its successor. Should
any instrument in writing from the Issuer be required by any successor Trustee
for more fully and certainly vesting in such successor the estate properties,
rights, powers and duties hereby vested or intended to be vested in the
predecessor, any and all such instruments in writing shall, on request, be
executed, acknowledged and delivered by the Issuer. The resignation of any
Trustee and the instrument or instruments removing any Trustee and appointing a
successor hereunder, together with all other instruments provided for in this
Article shall be filed and/or recorded by the successor Trustee in each
recording office where the Indenture shall have been filed and/or recorded.

     SECTION 1210. Right Of Trustee to Pay Taxes and Other Charges. In case any
tax, assessment or governmental or other charge upon any part of the Trust
Estate is not paid as required herein, the Trustee may pay such tax, assessment
or governmental or other charge, without prejudice, however, to any rights of
the Trustee or the Bondholders hereunder arising in consequence of such failure;
and any amount at any time so paid under this Section, with interest thereon
from the date of payment at the rate of interest which is one percent (1%)
higher than the highest rate of interest borne by any of the Bonds, shall become
so much additional indebtedness secured by this Indenture, and the same shall be
given a preference in payment over any of the Bonds, and shall be paid out of
the proceeds of revenues collected from the property herein conveyed, if not
otherwise caused to be paid; but the Trustee shall be under no obligation to
make any such payment unless it shall have been requested to do so in writing by
the holders of at least twenty-five percent

                                      -34-

(25%) in aggregate principal amount of all Bonds then outstanding and shall have
been provided with adequate funds for the purpose of such payment.

     SECTION 1211. Trustee Protected in Relying Upon Resolutions, etc. The
resolutions, opinions, certificates and other instruments provided for in this
Indenture may be accepted by the Trustee as conclusive evidence of the facts and
conclusions stated therein and shall be full warrant, protection and authority
to the Trustee for the release of property and the withdrawal of cash hereunder.

     SECTION 1212. Successor Trustee as Trustee of Bond Fund; Paying Agent and
Registrar. In the event of a change in the office of Trustee, the predecessor
Trustee which has resigned or been removed shall cease to be trustee of the Bond
Fund and paying agent for principal and interest and premium, if any, on the
Bonds and registrar and the successor Trustee shall become such trustee, paying
agent and registrar.

     SECTION 1213. Trust Estate May be Vested in Separate or Co-Trustee. It is
the purpose of this Indenture that there shall be no violation of any law of any
jurisdiction (including particularly the law of the State) denying or
restricting the right of banking corporations or associations to transact
business as trustee in such jurisdiction. It is recognized that in case of
litigation under this Indenture or the Lease Agreement, and in particular in
case of the enforcement of either on default, or in case the Trustee deems that
by reason of any present or future law of any jurisdiction it may not exercise
any of the powers, rights or remedies herein granted to the Trustee or hold
title to the Trust Estate, in trust, as herein granted, or take any other action
which may be desirable or necessary in connection therewith, it may be necessary
that the Trustee appoint an additional individual or institution as a separate
or co-trustee. The following provisions of this Section 1213 are adopted to
these ends.

     In the event that the Trustee appoints an additional individual or
institution as a separate or co-trustee, each and every remedy, power, right,
claim, demand, cause of action, immunity, estate, title, interest and lien
expressed or intended by this Indenture to be exercised by or vested in or
conveyed to the Trustee with respect thereto shall be exercisable by and vested
in such separate or co-trustee but only to the extent necessary to enable such
separate or co-trustee to exercise such powers, rights and remedies, and every
covenant and obligation necessary to the exercise thereof by such separate or
co-trustee shall run to and be enforceable by either of them.

     Should any deed, conveyance or instrument in writing from the Issuer be
required by the separate trustee or co-trustee so appointed by the Trustee for
more fully and certainly vesting in and confirming to him such properties,
rights, powers, trusts, duties and obligations, any and all such deeds,
conveyances and instruments in writing shall, on request, be executed,
acknowledged and delivered by the Issuer. In case any separate trustee or
co-trustee, or a successor to either, shall die, become incapable of acting,
resign, or be removed, all the estates properties, rights, powers, trusts,
duties and obligations of such separate trustee or co-trustee, so far as
permitted by law, shall vest in and be exercised by the Trustee until the
appointment of a new trustee or successor to such separate trustee or
co-trustee.

     SECTION 1213. Trustee Not Responsible for Insurance, Taxes or Execution of
Indenture. The Trustee shall not be under any obligation to effect or maintain
insurance or to renew any policies of insurance or to inquire as to the
sufficiency of any policies of insurance carried by the Lessee or to report, or
make or file claims or proof of loss for, any loss or damage insured against or
which may occur, or to keep itself informed or advised as to the payment of any
taxes or assessments, or to require any such payment to be made. The Trustee
shall have no responsibility in respect of the validity, sufficiency, due
execution or acknowledgment of this Indenture or the validity or sufficiency of
the security provided hereunder or in respect of the validity of the Bonds or
the due execution or issuance thereof, except as to the authentication thereof.

                             SUPPLEMENTAL INDENTURES

     SECTION 1301. Supplemental Indentures Not Requiring Consent of Bondholders.
The Issuer and the Trustee may, without the consent of, or notice to, any of the
Bondholders, enter into an indenture, or indentures supplemental to this
Indenture as shall not be inconsistent with the terms and provisions hereof for
any one or more of the following purposes:

          (a) To cure any ambiguity or formal defect or omission in this
     Indenture;

          (b) To grant to or confer upon the Trustee for the benefit of the
     Bondholders any additional rights, remedies, powers or authority that may
     lawfully be granted to or conferred upon the Bondholders or the Trustee or
     either of them; and

          (c) To subject to the lien and pledge of this Indenture additional
     revenues, properties or collateral or to more precisely identify the
     revenues, properties or collateral subject to the lien of this Indenture.

     SECTION 1302. Supplemental Indentures Requiring Consent of Bondholders.
Exclusive of supplemental indentures covered by Section 1301 hereof and subject
to the terms and provisions contained in this Section, and not otherwise, the
holders of not less than two-thirds in aggregate principal amount of the Bonds
then outstanding shall have the right from time to time, anything contained in
this Indenture to the contrary notwithstanding, to consent to and approve in
writing the execution by the Issuer and the Trustee of such other indenture or
indentures supplemental hereto as shall be deemed necessary and desirable by the
Issuer for the purpose of modifying, altering, amending, adding to or
rescinding, in any particular, any of the terms or provisions contained in this
Indenture or in any supplemental indenture; provided, however, that nothing in
this Section contained shall permit, or be construed as permitting without the
consent of the holders of all the Bonds then outstanding (a) an extension of the
stated maturity or reduction in the principal amount of, or reduction in the
rate or extension of the time of payment of interest on, or the reduction of any
premium payable on the redemption of, any Bonds, or (b) the creation of any lien
on the Trust Estate (other than Permitted Encumbrances) prior to or on a parity
with the lien of this Indenture, or (c) a reduction in the aforesaid aggregate
principal amount of Bonds the holders of which are required to consent to any
such supplemental indenture. No such modification shall modify the rights,
duties or immunities of the Trustee, without the written consent of the Trustee.

     If at any time the Issuer shall request the Trustee to enter into any such
supplemental indenture for any of the purposes of this Section, the Trustee
shall, upon being satisfactorily indemnified with respect to expenses, cause
notice of the proposed execution of such supplemental indenture to be sent to
the address of each registered owner of Bonds as set forth in the Bond Register.
Such notice shall briefly set forth the nature of the proposed supplemental
indenture and shall state that copies thereof are on file at the principal
office of the Trustee for inspection by all Bondholders. If, within sixty days
(60) or such longer period as shall be prescribed by the Issuer following such
notice, the holders of not less than two-thirds in aggregate principal amount of
the Bonds outstanding at the time of the execution of any such supplemental
indenture shall have consented in writing to and approved the execution thereof
as herein provided, no holder of any Bond shall have any right to object to any
of the terms and provisions contained therein, or the operation thereof, or in
any manner to question the propriety of the execution thereof, or to enjoin or
restrain the Trustee or the Issuer from executing the same or from taking any
action pursuant to the provisions thereof. Upon the execution of any such
supplemental indenture as in this Section permitted and provided, this Indenture
shall be and redeemed to be modified and amended in accordance therewith.

                                      -36-

     The Trustee may receive, and may rely on, an Opinion of Counsel as
conclusive evidence that any indenture supplemental hereto entered into by the
Issuer and the Trustee complies with the provisions of this Article XIII.

     Anything herein to the contrary notwithstanding, so long as the Lessee is
not in default under the Lease Agreement and no event of default exists
hereunder, a supplemental indenture under this Article XIII which affects any
rights of the Lessee shall not become effective unless and until the Lessee
shall have consented in writing to the execution and delivery of such
supplemental indenture.

     SECTION 1401. Amendments, etc., to Lease Agreement Not Requiring Consent of

or modification of the Lease Agreement the Trustee shall, upon being
satisfactorily indemnified with respect to expenses, cause notice of such
proposed amendment, change or modification to be mailed in the same manner as
provided by Section 1302 hereof with respect to supplemental indentures. Such
notice shall briefly set forth the nature of such proposed amendment, change or
modification and shall state that copies of the instrument embodying the same
are on file at the principal office of the Trustee for inspection by all

or Base Rate. Upon the expiration of such Interest Period and any
Interest Period thereafter, the Lessee shall have the option to convert the
interest rate accruing on all (but not less than all) of the outstanding
principal balance of the Bonds into a Libor Rate or Base Rate; provided that (i)
Bonds cannot be converted when any Default has occurred and is continuing and in
such event the Bonds shall accrue interest at the Base Rate, and (ii) no
conversions of the Bonds are allowed until the expiration of the Interest Period
applicable to the existing rate of interest has expired.

     Each conversion shall be enacted by the Authorized Lessee Representative by
giving to the Trustee at its main office prior to 11:00 a. m. (New Orleans time)
on or before the last Business Day of the applicable Interest Period written or
telephone Notice of Conversion specifying if the Bonds are to be converted into
accruing interest at Libor Rate or Base Rate and the Interest Period to be
applicable thereto. In the absence of any specific rate election by the Lessee
or if Lessee fails to provide such notice to the Trustee in a timely manner, the
Bonds shall accrue interest at the Base Rate.

     Interest on the outstanding principal owed on the Bonds shall be computed
and assessed on the basis of the actual number of days elapsed over a year
composed of 360 days.

     Additionally, with respect to each Interest Period, in the event that the
Bondholder shall have determined in good faith (which determination shall,
absent manifest error, be final and conclusive and binding upon all parties
hereto):

          (i) on any Interest Period or date of conversion that, by reason of
     any changes arising after the date of this Indenture affecting the London
     interbank market, adequate and fair means do not exist for ascertaining the
     applicable interest rate on the basis provided for in the definition of
     Libor Rate; or

          (ii) at any time, that the Bondholder shall incur increased costs or
     reductions in the amounts received or receivable hereunder with respect to
     any Libor Rate because of any change since the date of this Indenture in
     any applicable law or governmental rule, regulation, order, guideline or
     request or in the interpretation or administration thereof and including
     the introduction of any new law or governmental rule, regulation, order,
     guideline or request, such as, for example, but not limited to: (A) a
     change in the basis of taxation of payment to the Bondholder of the
     principal or interest on such Libor Rate (except for changes in the rate of
     tax on, or determined by reference to, the net income or profits of the
     Bondholder) or (B) a change in official reserve requirements; or

          (iii) at any time, that the making or continuance of any Libor Rate
     has been made (x) unlawful by any law or governmental rule, regulation or
     order, (y) impossible by compliance by the Bondholder in good faith with
     any governmental request (whether or not having force of law) or (z)
     impracticable as a result of a contingency occurring after the date of this
     Indenture which materially and adversely affects the London interbank
     market;

then, and in any such event, the Bondholder shall promptly give notice (by
telephone confirmed in writing) to the Lessee. Thereafter (x) in the case of
clause (i) above, the Libor Rate shall no longer be available until such time as
the Bondholder notifies the Lessee that the circumstances giving rise to such
notice no longer exist, the Bonds shall then accrue interest at the Base Rate,
and any Notice of Conversion given by the Lessee with respect to the Libor Rate
which have not yet been incurred (including by way of conversion) shall be
deemed rescinded by the Lessee, (y) in the case of clause (ii) above, the Lessee
agrees to pay to the Bondholder, upon written demand therefor, such additional
amounts (in the form of an increased rate of, or a different method of
calculating, interest or otherwise as agreed to by the Bondholder and the
Lessee) as shall be required to compensate the Bondholder for such increased
costs or reductions in amounts received or receivable

<PAGE>

hereunder (a written notice as to the additional amounts owed to the Bondholder,
showing the basis for the calculation thereof, submitted to the Lessee by the
Bondholder in good faith shall, absent manifest error, be final and conclusive
and binding on all the parties hereto) and (z) in the case of clause (iii)
above, the Bonds shall accrue interest at the Base Rate. The Bondholder agrees
that if it gives notice to the Lessee of any of the events described in clause
(i) or (iii) above, it shall promptly notify the Lessee if such event ceases to
exist. If any such event described in clause (iii) above ceases to exist as to
the Bondholder, the Bondholder's obligations to convert the interest accruing on
the Bonds into Libor Rate on the terms and conditions contained herein shall be
reinstated.

     All interest shall be computed on the basis of the actual number of days
elapsed over a year composed of 360 days. Interest will be due and payable on
the first day of each month, commencing September 1, 2003. Prepayments of
principal shall be noted by the Bondholder on Schedule A hereto. The principal
of and premium, if any, and interest on this Bond are payable in lawful money of
the United States of America by check or draft mailed to the registered owner
hereof whose name is registered at the close of business on the fifteenth
calendar day preceding any such payment date at the address of such owner as it
appears on the Bond Register kept by the Trustee except as set forth in the
Indenture with respect to a single owner of all Bonds outstanding. The term
"Trustee", when herein used, means The Bank of New York Trust Company of
Florida, N. A., of Jacksonville, Florida, or any successor trustee and
co-trustee under the Indenture mentioned below.

     Payments of principal and interest, including prepayments of principal,
shall be noted on the appropriate payment record made a part of this Bond.

     This Bond is one of an authorized issue of Taxable Revenue Bonds (Conrad
Aluminum, L.L.C. Project) Series 2003 (the "Bonds") limited in aggregate
principal amount to $4,000,000, authorized by a resolution duly adopted by the
Board of Directors of the Issuer, the governing authority of the Issuer, all
issued or to be issued under a Trust Indenture dated as of June 1, 2003 (the
"Indenture") made from the Issuer to the Trustee, pursuant to and in full
conformity with the Constitution and the laws of the State of Louisiana, in
particular the provisions of Chapter 7 of Title 51 of the Louisiana Revised
Statutes of 1950, as amended. Payment of the principal of, premium, if any, and
interest on the Bonds has been guaranteed by Conrad Industries, Inc., a Delaware
corporation, Conrad Shipyard, L.L.C., a Louisiana limited liability company,
Orange Shipbuilding Company, Inc., a Texas corporation and Conrad Aluminum,
L.L.C., a Louisiana limited liability company (the "Lessee"), pursuant to a
Guaranty Agreement dated as of June 1, 2003 entered into for the benefit of the
holders of the Bonds (the "Guaranty Agreement"). The Bonds are issued for the
purpose of providing a portion of the moneys necessary to finance the
acquisition, construction and equipping of an aluminum marine fabrication,
repair and conversion facility of the Lessee to be located in Amelia, St. Mary
Parish, Louisiana (the "Project"). The facilities (the "Leased Facilities") are
to be leased by the Issuer to the Lessee pursuant to a Lease Agreement between
the Issuer and the Lessee dated as of June 1, 2003 (the "Lease Agreement").
Reference is hereby made to the Indenture, the Lease Agreement and the Guaranty
Agreement, copies of which are filed with the Trustee, for the provisions, among
others, with respect to the nature and extent of the rights, duties and
obligations of the Issuer, the Lessee, the Trustee and the holders of the Bonds,
the terms upon which the Bonds are issued and secured, and the modification or
amendment of the Indenture, the Lease Agreement or the Guaranty Agreement, to
all of which the owner or holder of this Bond assents by the acceptance of this
Bond.

     The Bonds are issued in the form of a single fully registered bond.

     Upon payment of any required tax, fee or other governmental charge and
subject to the conditions provided in the Indenture, the Bonds, upon surrender
thereof at the office of the Corporate Trust Division of the Trustee with a
written instrument of transfer satisfactory to the Trustee, duly executed by the
registered

<PAGE>

owner thereof or his duly authorized attorney, may, at the option of the
registered owner thereof, be exchanged for an equal aggregate principal amount
of registered Bonds in any of the authorized denominations and registered in
such name or names as may be requested.

     This Bond shall be transferable only on the Bond Register (as defined in
the Indenture) upon surrender hereof at the office of the Corporate Trust
Division of the Trustee with a written instrument of transfer satisfactory to
the Trustee, duly executed by the Registered Owner hereof or his attorney duly
authorized in writing. Such transfer shall be without charge to the owner of
this Bond except that any tax, fee or other governmental charge required to be
paid with respect to such transfer shall be paid by the registered owner hereof
as a condition precedent to the exercise of such privilege.

     The Bonds are subject to redemption prior to maturity, in whole or in part,
at the option of the Issuer, as directed by the Lessee, on any date, at a
redemption price equal to the principal amount thereof plus accrued interest to
the redemption date.

     In the event any of the Bonds are called for redemption as aforesaid,
notice thereof identifying the Bonds to be redeemed shall be given by mailing a
copy of the redemption notice by first class mail, at least thirty (30) days
prior to the date fixed for redemption, to the registered owners of any Bonds to
be redeemed at their last addresses shown on the Bond Register. All Bonds so
called for redemption will cease to bear interest on the specified redemption
date, provided funds for their redemption are on deposit at the place of payment
at that time, and shall no longer be secured by the Indenture and shall not be
deemed to be outstanding under the provisions of the Indenture.

     The Bonds are limited obligations of the Issuer and are payable from the
Bond Fund and shall be a valid claim of the respective holders thereof only
against the funds and the revenues and receipts derived from the leasing of the
Leased Facilities by the Issuer to the Lessee pursuant to the Lease Agreement or
the sale of the Leased Facilities and are additionally secured by the Guaranty
Agreement. The Bonds do not now and shall never constitute an indebtedness or
pledge of the general credit of the Issuer, the Parish of St. Mary, the State of
Louisiana, or any political subdivision of said State, within the meaning of any
constitutional or statutory limitation of indebtedness. The rental payments or
payments under the Guaranty Agreement sufficient for the prompt payment when due
of the interest on and principal or premium, if any, of the Bonds, are to be
paid directly to the Trustee by the Lessee for the account of the Issuer and
deposited in a fund created by the Issuer and designated "Taxable Revenue Bond
Fund -- Conrad Aluminum, L.L.C. Project", and have been duly pledged for that
purpose under the Indenture to secure payment of such principal or premium, if
any, and interest.

     The holder of this Bond shall have no right to enforce the provisions of
the Indenture or to institute action to enforce the covenants therein, or to
take any action with respect to any event of default under the Indenture, or to
institute, appear in or defend any suit or proceedings with respect thereto,
except as provided in the Indenture. In certain events, on the conditions, in
the manner and with the effect set forth in the Indenture, the principal of all
of the Bonds issued under the Indenture and then outstanding may become or may
be declared due and payable before the stated maturity thereof, together with
interest accrued thereon. Modifications or alterations of the Indenture, or any
supplements thereto, may be made only to the extent and in the circumstances
permitted by the Indenture.

     It is hereby certified, recited and declared that all acts, conditions and
things required to exist, happen and be performed precedent to and in the
execution and delivery of the Indenture and the issuance of this Bond do exist,
have happened and have been performed in due time, form and manner as required
by law; and that the issuance of this Bond and the issue of which it forms a
part, together with all other obligations of the Issuer, does not exceed or
violate any constitutional or statutory limitation.

     This Bond shall not be valid or become obligatory for any purpose or be
entitled to any security or benefit under the Indenture until the certificate of
authentication hereon shall have been signed by the Trustee.
