                              CONVERTIBLE DEBENTURE

$10,651,563.70                   August 13, 2002

            FOR VALUE RECEIVED, UNIFAB International, Inc., a Louisiana
corporation (the "Company") for value received, hereby promises to pay to
Midland Fabricators and Process Systems, LLC, or registered assigns ("Payee")
the principal sum of Ten Million, Six Hundred Fifty-One Thousand, Five Hundred,
Sixty-Three and 70/100 Dollars ($10,651,563.70) (the "Principal Amount"), in
five (5) equal annual installments in the amount of Two Million, One Hundred
Thirty Thousand, Three Hundred Twelve and 74/100 Dollars ($2,130,312.74), plus
interest as provided for herein, commencing on August 13, 2007 and on the same
day of each of the next succeeding five (5) calendar years, unless sooner due
and payable as provided herein. All then accrued but unpaid interest shall be
due and payable concurrently with each installment of the Principal Amount. This
Convertible Debenture (the "Debenture") is a secured obligation of the Company.

      1.    INTEREST RATE AND TIMING OF INTEREST PAYMENTS.

            a.    The then outstanding Principal Amount shall bear simple
interest at the prime rate of interest published by the Wall Street Journal plus
2.50% per annum, calculated based upon a year of three hundred sixty-five (365)
days.

            b.    Interest only payments shall be due and paid quarterly, in
arrears, commencing on the fifteenth (15th) day of the first calendar quarter
that begins after the date hereof and continuing on the fifteenth day of each of
the following calendar quarters, until the Principal Amount has been paid in
full.

                                       1

<PAGE>

            c.    The interest so payable, and punctually paid or duly provided
for, on any interest payment date will be paid by wire transfer to the person in
whose name this Debenture is registered at the close of business on the record
date for such interest, which shall be the last day (whether or not a business
day) of the calendar month next preceding such interest payment date.

            d.    In no event shall the amount paid or agreed to be paid
hereunder (including all interest and the aggregate of any other amounts taken,
reserved or charged pursuant to this Debenture or any other document evidencing
or securing the loan evidenced hereby, which under applicable law is deemed to
constitute interest on the indebtedness evidenced by this Debenture) exceed the
highest lawful rate permissible under applicable law; and if under any
circumstance whatsoever, fulfillment of any provision of this Debenture, at the
time performance of such provision shall be due, shall involve transcending the
limit of validity prescribed by applicable law, then, ipso facto, the obligation
to be fulfilled shall be reduced to the limit of such validity, and if from any
circumstance, the holder of this Debenture should receive as interest an amount
which would exceed the highest lawful rate allowable under law, such amount
which would be excessive interest shall be refunded to the Company.

      2.    NO NOVATION. The issuance of this Debenture evidences a modification
of the unpaid balance ("Remaining Bank Debt") of the Company's "Secured
Obligations" pursuant to and as that term is defined in that certain Credit
Agreement by and among the Company, as borrower, and Bank One, N.A. (as
successor by merger to Bank One, Louisiana, N.A.), as agent, and the Lender's
party thereto dated November 30, 1999. The parties acknowledge that the issuance
of this Debenture shall not effect a novation of the Remaining Bank Debt or a
release of the security therefore, but only a modification thereof.

      3.    PREPAYMENT. Company reserves the right to repay this Debenture in
full or in part without penalty at any time. The Company shall give fifteen (15)
days notice to Payee of its intention to prepay and Payee shall have the
conversion rights set forth in Paragraph 5.

      4.    EVENTS OF DEFAULT AND REMEDIES.

            a.    Any one of the following occurrences shall constitute an
"Event of Default" under this Debenture:

            (1)   The failure by the Company to make any payment of principal or
interest under this Debenture as and when the same becomes due and payable in

                                       2

<PAGE>

accordance with the terms hereof, which failure is not cured within five (5)
business days following notice thereof to the Company;

            (2)   The occurrence of any default under any material provision of
this Debenture other than as described in the preceding clause (1) which default
is not cured within thirty (30) days following notice thereof to the Company; or

            (3)   The Company applies for, consents to or acquiesces in the
appointment of, a trustee, receiver or other custodian for itself or a
substantial part of its property, or makes a general assignment for the benefit
of creditors; or in the absence of such application, consent or acquiescence, a
trustee, receiver or other custodian is appointed for the Company or for a
substantial part of its property, and is not discharged within thirty (30) days;
or another case or proceeding under any bankruptcy or insolvency law, or any
dissolution or liquidation proceeding is commenced in respect of the Company,
and if such case or proceeding is not commenced by the Company, it is consented
to or acquiesced in by the Company or remains for thirty (30) days undismissed;
or the Company takes any action to authorize, or in furtherance of, any of the
foregoing.

            b.    Upon the occurrence of any Event of Default hereon (i) the
entire unpaid principal balance of, and unpaid interest then accrued on, and any
other amounts owing under or evidenced by this Debenture shall, at the option of
the registered owner hereof and without notice or demand of any kind to the
Company or any other person, immediately become due and payable; and (ii) the
registered owner hereof shall have and may exercise any and all rights and
remedies available at law or in equity. The remedies of the registered owner
hereof, as provided herein, shall be cumulative and concurrent, and may be
pursued singularly, successively or together, at the sole discretion of the
registered owner hereof, and may be exercised as often as occasion therefore
shall arise. No act of omission or commission of the registered owner,
including, specifically, the failure to exercise any right, remedy or recourse,
shall be deemed to be a waiver or release of the same, such waiver or release to
be effected only through a written document executed by the registered owner and
then only to the extent specifically recited therein. A waiver or release with
reference to any one event shall not be construed as continuing, as a bar to, or
as a waiver or release of any subsequent right, remedy or recourse as to a
separate or subsequent event.

      5.    CONVERSION. This Debenture shall be convertible into shares of the
Company's common stock, par value $.01 per share ("Common Stock") as follows:

            a.    The registered owner hereof shall be entitled to convert any
portion of the face amount of the Debenture into fully paid and non-assessable
shares of the

                                       3

<PAGE>

Company's Common Stock at any time from the date of this Debenture at a price of
$0.35 per share (the "Conversion Price"). After conversion or repayment of all
amounts of principal and interest due under the Debentures, the Company shall
have no further obligations to the Payee. After August 13, 2011 [the date the
final installment is due, the "Outside Date"], the holder hereof shall have no
conversion rights hereunder, without the written consent of the Company, which
may be withheld for any reason.

            b.    This Debenture may be converted into Common Stock as provided
herein by giving written notice to the Company on or before the earlier of the
Outside Date or seven (7) days following receipt of notice of prepayment of this
Debenture as set forth in Section 3 hereof. Such written notice shall be signed
by the registered owner hereof, shall state the amount of the then outstanding
principal balance and accrued and unpaid interest which the registered owner
seeks to convert into shares of Common Stock, shall contain the warranty
required by Section 8 hereof, and shall specify a date (other than a Saturday,
Sunday or legal holiday) not less than thirty (30) nor more than forty-five (45)
days after the date of such written notice, as the date on which such shares
will be taken up at the principal office of the Company during ordinary business
hours, or at such other hour and place agreed upon by the Company and the person
or persons exercising the conversion and shall otherwise comply with the terms
and conditions of this Debenture. On the date specified in such written notice
(which date may be extended by the Company if any law or regulation requires the
Company to take any action with respect to the shares prior to the issuance
thereof, whether pursuant to the provisions of Section 8 hereof or otherwise)
the registered owner shall present the Debenture to the Company which shall
inscribe thereon that portion of the face amount of the Debenture being
converted into shares.

            c.    The Company shall pay all original issue taxes, if any, with
respect to the issue of Common Stock pursuant hereto and all other fees and
expenses necessarily incurred by the Company in connection therewith. The
registered owner hereof shall have the rights of a shareholder only with respect
to those shares of Common Stock which have been registered in the registered
owner's name in the common share register of the Company maintained by the
Company's transfer agent upon conversion hereunder.

            d.    In the event this Debenture, or any portion thereof, is
converted into Common Stock of the Company, no fractional shares of Common Stock
shall be issued. In lieu of any fractional shares to which the registered owner
would otherwise be entitled, the Company shall pay cash equal to the amount of
the then outstanding principal balance such fractional share represents. The
portion of the Debenture that is converted pursuant to this Section 5 shall
cease to bear interest.

                                       4

<PAGE>

            e.    The Conversion Price shall be adjusted from time to time as
follows: If the Company effects any (i) dividend or other distribution upon or
in redemption of the Common Stock payable in the form of shares of capital stock
of the Company or any of its subsidiaries or in the form of any other property
(other than cash dividends paid in the ordinary course), (ii) combination of
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, (iii) split or other subdivision of outstanding shares of Common Stock
into a larger number of shares of Common Stock, or (iv) reorganization, exchange
or reclassification of Common Stock, or any consolidation or merger of the
Company with another corporation, or the sale of all or substantially all of its
assets to another corporation, or any other transaction effected in a manner
such that holders of outstanding Common Stock shall be entitled to receive
(either directly, or upon subsequent liquidation) stock, securities or other
property with respect to or in exchange for Common Stock (a "Diluting Event"),
then as a condition of such Diluting Event, lawful, appropriate, equitable and
adequate adjustments shall be made to the Conversion Price whereby the holder
Debenture shall thereafter be entitled to receive (under the same terms
otherwise applicable to their receipt of the Common Stock upon conversion of the
Debenture), in lieu of or in addition to, as the case may be, the number of
shares of Common Stock issuable under this Section 5, such shares of stock,
securities or other property as may be issued or payable with respect to or in
exchange for that number of shares of Common Stock to which such holder of the
Debenture was so entitled under this Section 5, and in any such case
appropriate, equitable and adequate adjustments shall also be made to such
resulting consideration in like manner in connection with any subsequent
Diluting Events. It is the intention of the parties that the foregoing shall
have the effect of entitling the holder of the Debenture to receive upon the due
exercise of its conversion rights under this Section 5 such stock, securities
and other property (other than cash dividends paid in the ordinary course) as
such holder would have received had it held the Common Stock issuable under this
Section 5 (or any replacement or additional stock, securities or property, as
applicable) on the record date of such Diluting Event. Upon the occurrence of
each adjustment or readjustment of the Conversion Price pursuant to this Section
5, the Company at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms thereof and furnish to the holder of
this Debenture a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.

            f.    In the event that prior to the Outside Date, the Company shall
engage in any capital reorganization, reclassification of the stock of the
Company, consolidation or merger of the Company with or without another
corporation, or sale or conveyance of all or substantially all of the assets of
the Company to another corporation, entity or person, or sale of the issued and
outstanding Common Stock to another corporation, entity or person, the Company
shall give written

                                       5

<PAGE>

notice to the registered owner hereof at least 30 days prior to the projected or
anticipated closing of any of the afore described transactions, setting forth in
said notice the date that the transaction will be closed or completed.
Thereafter, the registered owner hereof shall have the right to convert this
Debenture into Common Stock of the Company as provided in this Section 5, if and
only if, the registered owner hereof gives written notice to the Company no less
than 15 days prior to the anticipated closing or completion date of the
aforesaid transaction, and should such notice not be delivered on a timely
basis, the conversion rights hereunder shall lapse.

      6.    VOTING RIGHTS.        No registered owner shall, solely by virtue of
ownership of this Debenture, be entitled to any rights whatsoever, of a
shareholder of the Company, including but not limited to voting rights. The
registered owner shall have only such rights, if any, to which he is entitled by
virtue of his ownership of this Debenture.

      7.    SUBORDINATION. This Debenture shall be subordinated only to (a) all
existing and future bank debt of the Company and (b) any secured financing
obtained by the Company, the proceeds of which the Company may use for any
purpose. In the event the registered owner hereof has exercised conversion
rights hereunder, any Common Stock of the Company so acquired shall be
subordinate to all secured and unsecured debt of the Company and to the rights
of preferred shareholders of the Company.

      8.    PURCHASE FOR INVESTMENT. The Company shall be under no obligation to
issue shares of the Company's Common Stock hereunder, unless the person who
exercises conversion rights shall warrant to the Company, at the time of such
exercise, that such person is acquiring the shares to be issued to such person
pursuant to such conversion rights, for investment and not with a view to, or
for sale in connection with, the distribution of any such shares; and in such
event, the person acquiring such shares shall be bound by the provisions of the
following legend or similar legend which shall be endorsed upon the certificate
or certificates evidencing the shares issued by the Company pursuant to such
exercise:

            "The shares represented by the certificate have been
            taken for investment and they may not be sold or
            otherwise transferred by any person, including a
            pledgee, in the absence of an effective registration
            statement for the shares under the Securities Act of
            1933, as amended, or an opinion of counsel satisfactory
            to the Company that an exemption from registration is
            then available."

      9.    TRANSFER. The registered owner hereof covenants that this Debenture
has been acquired for investment. The Debenture cannot be sold or otherwise

                                       6

<PAGE>

transferred by the registered owner or any other person, including a pledgee, in
the absence of a registration of the Debenture under the Securities Act of 1933,
as amended, or an opinion of counsel satisfactory to the Company that an
exemption from registration is then available. No transfer of the Debenture
shall be effective unless the Company is notified of such transfer, and unless
such transfer is registered on the records of the Company.

      10.   NOTICES. All notices or other communications hereunder to either
party shall be in writing and, if mailed, shall be deemed to be given on the
second business day after the date when deposited in the United States mail, by

law.

      13.   MISCELLANEOUS.

any, provided for in this Indenture relating to the proposed action have been

SECTION 103       FORM OF DOCUMENTS DELIVERED TO TRUSTEE
                  --------------------------------------

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be certified or covered by only one 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. An Opinion of Counsel may be rendered insofar as it
relates to matters of New York law in reliance on an opinion of New York counsel
which may be an opinion contemporaneously delivered to a third party or parties
and shall expressly permit such reliance.

         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 104       ACTS OF HOLDERS
                  ---------------

         (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 Holders in person or by agent duly
appointed in writing. 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 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

                                       7
<PAGE>

         (b)      The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority.

         (c)      The principal amount and serial numbers of Senior Notes held
by any Person, and the date of holding the same, shall be proved by the Security
Register.

         (d)      Any request, demand, authorization, direction, notice,
consent, election, waiver or other Act of the Holder of any Senior Note shall
bind every future Holder of the same Senior Note and the Holder of every Senior
Note 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 Senior Note.

         (e)      The fact and date of execution of any such instrument or
writing and the authority of the Person executing the same may also be proved in
any other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

         (f)      If the Company shall solicit from the Holders of Senior Notes
of any series any Act, the Company may, at its option, by Board Resolution, fix
in advance a record date for the determination of Holders of Senior Notes
entitled to take such Act, but the Company shall have no obligation to do so.
Any such record date shall be fixed at the Company's discretion. If such a
record date is fixed, such Act may be sought or given before or after the record
date, but only the Holders of record at the close of business on such record
date shall be deemed to be Holders of Senior Notes for the purpose of
determining whether Holders of the requisite proportion of Senior Notes of such
series Outstanding have authorized or agreed or consented to such Act, and for
that purpose the Senior Notes of such series Outstanding shall be computed as of
such record date.

SECTION 105.      NOTICES, ETC., TO TRUSTEE AND COMPANY
                  -------------------------------------

         Any request, demand, authorization, direction, notice, consent,
election, 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,

                  (1)      the  Trustee by any Holder of a Senior Note or by
the Company shall be sufficient for every purpose  hereunder if made, given,
furnished or filed in writing to or with the Trustee,  100 Ashford Center
North, Suite 520, Atlanta, Georgia 30338, Attention: Corporate Trustee
Administration Department, or

                                       8
<PAGE>

                  (2)      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 270 Peachtree Street, N.W.,
Atlanta, Georgia 30303, or at any other address previously furnished in writing
to the Trustee by the Company.

SECTION 106       NOTICE TO HOLDERS OF SENIOR NOTES; WAIVER
                  -----------------------------------------

         Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Senior Notes of any event, such notice shall
be sufficiently given 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, and not earlier than the earliest
date, prescribed for the giving of such Notice.

         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. 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 of Senior Notes 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.

SECTION 107       CONFLICT WITH TRUST INDENTURE ACT
                  ---------------------------------

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required to be a part of and govern this
Indenture, such required provision shall control.

SECTION 108       EFFECT OF HEADINGS AND TABLE OF CONTENTS
                  ----------------------------------------

         The Article and Section headings herein and the Table of Contents are

SECTION 112       GOVERNING LAW
                  -------------

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

Maturity of any Senior Note shall not be a Business Day, then (notwithstanding
any other provision of this Indenture or of the Senior Notes) payment of
interest or principal (and premium, if any) need not be made on such date, but
may be made on the next succeeding Business Day, except that, if such Business
Day is in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be.

         (a)      If the Company shall establish pursuant to Section 301 that

Security, the Depositary for such Global Security may surrender such Global
Security in exchange in whole or in part for individual Senior Notes of such
series of like tenor and terms 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 service charge,

Company Order to be delivered pursuant to Section 302 with respect thereto.

redeliver any such Global Security in the manner and upon instructions given by

                  (14)     whether the Senior Notes of the series shall be
issued in whole or in part in the form of a Global Security or Securities; the
terms and conditions, if any, upon which such Global Security or Securities may
be exchanged in whole or in part for certificated Senior Notes of such series
and of like tenor of any authorized denomination and the circumstances under
which such exchange may occur, if other than in the manner provided for in
Section 203; the Depositary for such Global Security or Securities; and the form
of any legend or legends to be borne by any such Global Security in addition to
or in lieu of the legend referred to in Section 203;

                  (15)     any restriction or condition on the transferability
of such Senior Notes;

                  (16)     the terms of any right to  convert  or  exchange
such  Senior  Notes  into or for other securities or property of the Company;

                  (17)     CUSIP numbers; and

                  (18)     any other terms of the series.

         All Senior Notes of any one series shall be substantially identical
except as to the date or dates from which interest, if any, shall accrue and
denomination and except as may otherwise be provided in the terms of such Senior
Notes determined or established as provided above. All Senior Notes of any one
series need not be issued at the same time and, unless otherwise provided, a
series may be reopened for issuances of additional Senior Notes of such series.

SECTION 302       EXECUTION, AUTHENTICATION, DELIVERY AND DATING
                  ----------------------------------------------

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

         Senior Notes bearing the manual or facsimile signatures of individuals
who were at the time relevant to the authorization thereof the proper officers
of the Company shall bind the Company, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of such Senior Notes or did not hold such offices at the date of such
Senior Notes.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Senior Notes of any series executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Senior Notes, and the Trustee, in
accordance with the Company Order, shall authenticate and deliver such Senior
Notes. If all of the Senior Notes of any series are not to be issued at one time
and if the supplemental indenture establishing such series shall so permit, such
Company Order may set forth procedures acceptable to the Trustee for the
issuance of such Senior Notes and determining the terms of particular Senior
Notes of such series, such as interest rate, maturity date, date of issuance and
date from which interest shall accrue. In authenticating Senior Notes hereunder,
and accepting the additional responsibilities under this Indenture in relation
to such Senior Notes, the Trustee shall be entitled to receive, and (subject to
Section 601) shall be fully protected in relying upon:

                                       15
<PAGE>

                  (1)      an Opinion of Counsel, to the effect that:

                           (a)      the form and terms of such  Senior Notes or
the manner of determining such terms have been established in conformity with
the provisions of this Indenture; and

                           (b) such Senior Notes, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to
any conditions specified in such Opinion of Counsel, will constitute valid and
legally binding obligations of the Company, enforceable in accordance with their
terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization and
other laws of general applicability relating to or affecting the enforcement of
creditors' rights and to general equity principles; and

                  (2)      an Officers' Certificate stating, to the best
knowledge of each signer of such certificate, that no event which is, or after
notice or lapse of time would become, an Event of Default with respect to any of
the Senior Notes shall have occurred and be continuing.

The Trustee shall not be required to authenticate such Senior Notes if the issue
of such Senior Notes pursuant to this Indenture will affect the Trustee's own
rights, duties or immunities under the Senior Notes and this Indenture or
otherwise in a manner which is not reasonably acceptable to the Trustee.

         If all the Senior Notes of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel and Officers'
Certificate at the time of issuance of each such Senior Note, but such opinion
and certificate shall be delivered at or before the time of issuance of the
first Senior Note of such series to be issued.

         Each Senior Note shall be dated the date of its authentication.

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

SECTION 303       REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE
                  ---------------------------------------------------

         The Company shall cause to be kept at the office of the Security
Registrar designated pursuant to this Section 303 or Section 1002 a register
(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 Senior Notes and of transfers of Senior Notes. The Trustee is hereby
initially appointed as Security Registrar for the purpose of registering Senior
Notes and transfers of Senior Notes as herein provided.

                                       16
<PAGE>

         Subject to Section 203, upon surrender for registration of transfer of
any Senior Note of any series at the office or agency maintained for such
purpose for such series, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Senior Notes of the same series, Stated Maturity
and original issue date, of any authorized denominations and of like tenor and
aggregate principal amount.

         Subject to Section 203, Senior Notes of any series may be exchanged, at
the option of the Holder, for Senior Notes of the same series, Stated Maturity
and original issue date, of any authorized denominations and of like tenor and
aggregate principal amount, upon surrender of the Senior Notes to be exchanged
at any such office or agency.

         Whenever any Senior Notes are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Senior Notes
that the Holder making the exchange is entitled to receive.

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

         Every Senior Note 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.

         No service charge shall be made for any registration of transfer or
exchange of Senior Notes, 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 Senior Notes, other
than exchanges pursuant to Section 304, 907 or 1107 not involving any transfer.

         The Company shall not be required (i) to issue, to register the
transfer of or to exchange Senior Notes of any series during a period of 15 days
immediately preceding the date notice is given identifying the serial numbers of
the Senior Notes of that series called for redemption, or (ii) to issue, to
register the transfer of or to exchange any Senior Notes so selected for
redemption in whole or in part, except the unredeemed portion of any Senior Note
being redeemed in part.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

SECTION 304       MUTILATED, DESTROYED, LOST AND STOLEN SENIOR NOTES
                  --------------------------------------------------

         If any mutilated Senior Note is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Senior Note of the same series, Stated Maturity and original
issue date, and 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 Senior Note 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 Senior Note has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Senior
Note, a new Senior Note of the same series, Stated Maturity and original issue
date, and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

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

         Upon the issuance of any new Senior Note under this Section, 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 Senior Note of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Senior Note shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Senior Note shall be at any time enforceable by anyone, and any
such new Senior Note shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Senior Notes of that series
duly issued hereunder.

         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 Senior Notes.

SECTION 305       PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED
                  ----------------------------------------------

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Senior Notes, interest on any Senior Note that 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 Senior Note (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 Senior Note of any series that 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:

                                       18
<PAGE>

                  (1)      The Company may elect to make payment of any
Defaulted Interest to the Persons in whose names the Senior Notes of such series
(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 Senior Note of such series 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 of Senior Notes of such
series at the address of such Holder 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 Senior Notes of such series (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 on the Senior Notes of any series in any other lawful manner not
inconsistent with the requirements of any securities exchange on which such
Senior Notes 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 Senior Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Senior Note shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Senior Note.

SECTION 306       PERSONS DEEMED OWNERS
                   --------------------

         Prior to due presentment of a Senior Note 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 Senior Note is registered as the absolute owner of
such Senior Note for the purpose of receiving payment of principal of (and

                                       19
<PAGE>

premium, if any) and (subject to Section 305) interest on such Senior Note and
for all other purposes whatsoever, whether or not such Senior Note 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 307       CANCELLATION
                  ------------

         All Senior Notes surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by the Trustee. The Company may at any time
deliver to the Trustee for cancellation any Senior Notes previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Senior Notes so delivered shall be canceled by the
Trustee. No Senior Notes shall be authenticated in lieu of or in exchange for
any Senior Notes canceled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Senior Notes held by the Trustee
shall be disposed of in accordance with a Company Order and the Trustee shall
promptly deliver a certificate of disposition to the Company or, in the absence
of such a Company Order, shall be returned to the Company.

SECTION 308       COMPUTATION OF INTEREST
                  -----------------------

         Except as otherwise specified as contemplated by Section 301 for Senior
Notes of any series, interest on the Senior Notes of each series shall be
computed on the basis of a 360-day year consisting of twelve 30-day months.

SECTION 309       CUSIP NUMBERS
                  -------------

         The Company in issuing the Senior Notes may use "CUSIP" numbers, and,
if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a
convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Senior Notes or as contained in any notice of redemption and that
reliance may be placed only on the identification numbers printed on the Senior
Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the "CUSIP" numbers.

SECTION 401       SATISFACTION AND DISCHARGE OF INDENTURE
                   --------------------------------------

         This Indenture shall, upon Company Request, cease to be of further
effect (except as to any surviving rights of registration of transfer or
exchange of Senior Notes herein expressly provided for) and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

                  (1)      either

                           (A) all Senior Notes theretofore authenticated and
delivered (other than (i) Senior Notes that have been destroyed, lost or stolen
and that have been replaced as provided for in Section 304 and (ii) Senior Notes
for whose payment money has theretofore been deposited in trust or segregated
and held in trust by the Company and thereafter repaid to the Company or
discharged from such trust, as provided in Section 1003) have been delivered to
the Trustee for cancellation; or

                           (B)      all such Senior Notes not theretofore
delivered  to the Trustee for cancellation have become due and payable, or have
been called for redemption,

         and the Company, in the case of (B) above, has deposited or caused to
be deposited with the Trustee as funds in trust for the purpose described above
an amount sufficient to pay and discharge the entire indebtedness on such Senior
Notes not theretofore delivered to the Trustee for cancellation, for principal
(and premium, if any) and interest to the date of the Stated Maturity or
Redemption Date, as the case may be, or if later, the date of payment;

                  (2)      the Company has paid or caused to be paid all other
sums payable hereunder by the Company; and

                  (3)      the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture have been complied with.

         In the event there are Senior Notes of two or more series hereunder,
the Trustee shall be required to execute an instrument acknowledging
satisfaction and discharge of this Indenture only if requested to do so with
respect to Senior Notes of all series as to which it is Trustee and if the other
conditions thereto are met. In the event there are two or more Trustees
hereunder, then the effectiveness of any such instrument shall be conditioned
upon receipt of such instruments from all Trustees hereunder.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of

                                       21
<PAGE>

the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402       APPLICATION OF TRUST
                  --------------------

and applied by it, in accordance with the provisions of the Senior Notes, and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company or an Affiliate acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money has been deposited
with the Trustee.

         The occurrence of an event described in (5) and (6) of this Section 501
with respect to a Subsidiary shall not constitute an Event of Default if (x) the
creditors of such Subsidiary have no recourse to the Company or (y) such
Subsidiary is not a "significant subsidiary" as defined in Regulation S-X under
the Securities Act.

SECTION 502       ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT
                  --------------------------------------------------

         If an Event of Default (other than an Event of Default specified in
Section 501(7) or 501(8) with respect to Senior Notes of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Senior Notes
of that series may declare the principal amount of and accrued interest on all
of the Senior Notes of that series 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 amount (or specified amount) shall
become immediately due and payable. If an Event of Default specified in Section
501(7) or (8) occurs, the principal of and interest on all the Senior Notes

                                       23
<PAGE>

shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders.

         At any time after such a declaration of acceleration with respect to
Senior Notes of any series 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 not less than a majority in principal amount of
the Outstanding Senior Notes of that series, by written notice to the Company
and the Trustee, may rescind and annul such declaration and its consequences if

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

                           (A)      all overdue interest on all Senior Notes of
that series,

                           (B)      the  principal of (and  premium,  if any)
any Senior Notes of that series which have become due  otherwise  than by such
declaration of  acceleration and interest  thereon at the rate or rates
prescribed therefor in such Senior Notes,

                           (C)      to the extent that payment of such interest

hereunder and the reasonable compensation, expenses, disbursements and advances
of the Trustee,  its agents and counsel, and any other amounts due to the
Trustee under Section 607; and

                  (2)      all Events of Default with respect to Senior Notes of
that series, other than the non-payment of the principal of Senior Notes of that
series which have become due solely by such declaration of acceleration, have
been cured or waived as provided in Section 513.

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

SECTION 503.               COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
                           BY TRUSTEE
                           ----------------------------------------------------

         The Company covenants that if an Event of Default occurs under Section
501(1), (2) or (3) with respect to any Senior Notes the Company will, upon
demand of the Trustee, pay to it, for the benefit of the Holders of such Senior
Notes, the whole amount then due and payable on such Senior Notes for principal
(and premium, if any) and interest and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal (and
premium, if any) and on any overdue interest, at the rate or rates prescribed
therefor in such Senior Notes, 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, and any other amounts due to the Trustee under Section
607.

                                       24
<PAGE>

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Senior Notes and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Senior Notes,
wherever situated.

         If an Event of Default with respect to Senior Notes of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Senior Notes of such
series 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 in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504       TRUSTEE MAY FILE PROOFS OF CLAIM
                  --------------------------------

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the Senior
Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Senior
Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

                  (1)      to file and prove a claim for the whole amount of
principal (and premium, if any) and interest owing and unpaid in respect of the
Senior Notes and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due to the Trustee under
Section 607) and of the Holders of Senior Notes allowed in such judicial
proceeding, and

                  (2)      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 of Senior Notes 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 of Senior Notes, 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 607.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Senior
Note any plan of reorganization, arrangement, adjustment or composition
affecting the Senior Notes or the rights of any Holder thereof or to authorize
the Trustee to vote in respect of the claim of any Holder of a Senior Note in
any such proceeding.

Notes may be prosecuted and enforced by the Trustee without the possession of
any of the Senior Notes 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,

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 607; and

                  Second:  To the payment of the amounts then due and unpaid

if any) and interest, respectively; and

                  Third:  The balance, if any, to the Person or Persons
entitled thereto.

hereunder, unless:

                  (1)      such Holder has previously given written notice to
the Trustee of a continuing Event of Default with respect to the Senior Notes of
that series;

                  (2)      the Holders of not less than 25% in principal amount

<PAGE>

                  (3)      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;

                  (4)      the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity has failed to institute any such
proceeding; and

                  (5)      no direction inconsistent with such written request
has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Senior Notes of that series;

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

                           PREMIUM AND INTEREST
                           ----------------------------------------------------

         Notwithstanding any other provision in this Indenture, the Holder of

Section 305) interest on such Senior Note on the due dates expressed in such
Senior Note (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

SECTION 509       RESTORATION OF RIGHTS AND REMEDIES
                  ----------------------------------

         If the Trustee or any Holder of a Senior Note 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 of Senior Notes 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.

of mutilated, destroyed, lost or stolen Senior Notes in the last paragraph of
Section 304, no right or remedy herein conferred upon or reserved to the Trustee

or remedy, and every right and remedy shall, to the 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.

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

         No delay or omission of the Trustee or of any Holder of any Senior Note
to exercise any right or remedy 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 of Senior Notes may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders
of Senior Notes.

SECTION 512       CONTROL BY HOLDERS OF SENIOR NOTES
                  ---------------------------------

         The Holders of not less than a majority in principal amount of the
Outstanding Senior Notes of any series 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, with respect
to the Senior Notes of such series, provided that

                  (1)      such direction shall not be in conflict with any rule
of law or with this Indenture, and could not involve the Trustee in personal
liability in circumstances where reasonable indemnity would not be adequate, and

                  (2)      the Trustee may take any other action deemed proper
by the Trustee which is not inconsistent with such direction.

SECTION 513       WAIVER OF PAST DEFAULTS

         The Holders of not less than a majority in principal amount of the
Outstanding Senior Notes of any series may, on behalf of the Holders of all the
Senior Notes of such series, waive any past default hereunder with respect to
such series and its consequences, except a default

                  (1)      in the payment of the  principal of (or premium,
if any) or interest on any Senior Note of such series, or

                  (2)      in respect of a covenant or provision hereof which
under Article Nine cannot be modified or amended without the consent of the
Holder of each Outstanding Senior Note of such series 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.

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

         All parties to this Indenture agree, and each Holder of any Senior Note
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, 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, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Senior Notes of any series, or to any suit instituted
by any Holder of any Senior Note for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Senior Note on or after the

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.

         (a)      Except during the continuance of an Event of Default with
respect to Senior Notes of any series,

                  (1)      the Trustee undertakes to perform, with respect to
Senior Notes of such series, such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

                  (2)      in the absence of bad faith on its part, the Trustee
may, with respect to Senior Notes of such series, conclusively rely, as to the
truth of the statements and the correctness of the opinions expressed therein,

                                       29
<PAGE>

upon certificates or opinions furnished to the Trustee and conforming to the
requirements of this Indenture; but in the case of any such certificates or
opinions which by any provision hereof are specifically required to be furnished
to the Trustee, the Trustee shall be under a duty to examine the same to
determine whether or not they conform to the requirements of this Indenture (but
need not confirm or investigate the accuracy of mathematical calculations or
other facts stated therein).

         (b)      In case an Event of Default with respect to Senior Notes of
any series has occurred and is continuing, the Trustee shall exercise, with
respect to Senior Notes of such series, 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 man would exercise or use under the circumstances in the
conduct of his own affairs.

         (c)      No provision of this Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that

                  (1)      this Subsection shall not be construed to limit the
effect of  Subsection  (a) of this Section;

                  (2)      the Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer, unless it shall be proved
that the Trustee was negligent in ascertaining the pertinent facts;

                  (3)      the Trustee shall not be liable with respect to any
action taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of a majority in principal amount of the Outstanding
Senior Notes of any series relating to the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred upon the Trustee, under this Indenture with respect to the
Senior Notes of such series; and

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.

         (d)      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.

of such series; and provided, further, that in the case of any default of the
character specified in Section 501(4) with respect to Senior Notes of such
series, no such notice to Holders shall be given until at least 45 days after

SECTION 610       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 in accordance with the
applicable requirements of Section 611.

         (b)      The Trustee may resign at any time with respect to the Senior
Notes of one or more series by giving written notice thereof to the Company. If
the instrument of acceptance by a successor Trustee required by Section 611
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee at the expense of the Company
may petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Senior Notes of such series.

         (c)      The Trustee may be removed at any time with respect to the
Senior Notes of any series by Act of the Holders of a majority in principal
amount of the Outstanding Senior Notes of such series delivered to the Trustee
and to the Company. If the instrument of acceptance by a successor Trustee
required by Section 611 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the resigning Trustee at the
expense of the Company may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Senior Notes of such
series.

         (d)      If at any time:

                  (1)      the Trustee shall fail to comply with Section 608
after written request therefor by the Company or by any Holder of a Senior Note
who has been a Holder of a Senior Note for at least six months, or

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

                  (3)      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, (i) the Company, by a Board Resolution, may remove the
Trustee with respect to all Senior Notes, or (ii) subject to Section 514, any
Holder of a Senior Note who has been a bona fide Holder of a Senior Note 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 with
respect to all Senior Notes and the appointment of a successor Trustee or
Trustees.

         (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, with
respect to the Senior Notes of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect

                                       34
<PAGE>

to the Senior Notes of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Senior Notes of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Senior Notes of any particular series) and shall comply with
the applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Senior Notes of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Senior Notes of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements of
Section 611, become the successor Trustee with respect to the Senior Notes of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Senior Notes of any series
shall have been so appointed by the Company or the Holders of Senior Notes and
accepted appointment in the manner required by Section 611, any Holder of a
Senior Note who has been a bona fide Holder of a Senior Note of such series 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 with respect to the Senior Notes of such series.

         (f)      The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Senior Notes of any series and each
appointment of a successor Trustee with respect to the Senior Notes of any
series by mailing written notice of such event by first-class mail, postage
prepaid, to all Holders of such series of Senior Notes as their names and
addresses appear in the Security Register.

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 the

with respect to the Senior Notes of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Senior Notes of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Senior Notes of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all

                                       35
<PAGE>

Senior Notes, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Senior Notes of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each 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 with respect
to the Senior Notes of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Senior Notes of that or those series to which the
appointment of such successor Trustee relates.

         (c)      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 referred
to in paragraph (a) or (b) of this Section, as the case may be.

the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

                           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 Senior Notes 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 Senior Notes so authenticated with the same
effect as if such successor Trustee had itself authenticated such Senior Notes.

SECTION 613       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 Senior Notes), the Trustee shall be subject to
the provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor). For purposes of Section
311(b)(4) and (6) of the Trust Indenture Act:

bankers and payable upon demand; and

         (b)      "self-liquidating paper" means any draft, bill of exchange,
acceptance or obligation which is made, drawn, negotiated or incurred by the
Company (or any such obligor) for the purpose of financing the purchase,
processing, manufacturing, shipment, storage or sale of goods, wares or
merchandise and which is secured by documents evidencing title to, possession
of, or a lien upon, the goods, wares or merchandise or the receivables or
proceeds arising from the sale of the goods, wares or merchandise previously
constituting the security, provided the security is received by the Trustee
simultaneously with the creation of the creditor relationship with the Company
(or any such obligor) arising from the making, drawing, negotiating or incurring
of the draft, bill of exchange, acceptance or obligation.

SECTION 614       APPOINTMENT OF AUTHENTICATING AGENT
                  -----------------------------------

         At any time when any of the Senior Notes remain Outstanding the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Senior Notes that shall be authorized to act on behalf of the Trustee to
authenticate Senior Notes of such series issued upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 304, and Senior
Notes 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 Senior Notes 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, 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, such 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, 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

                                       37
<PAGE>

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, 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 of Senior
Notes, if any, of the series with respect to which such Authenticating Agent
will serve, 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.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         The provisions of Sections 306, 604 and 605 shall be applicable to each
Authenticating Agent.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Senior Notes of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:

                  This is one of the Senior Notes of the series designated
therein  referred  to in  the within-mentioned Indenture.

SECTION 1001      PAYMENT OF PRINCIPAL AND INTEREST
                  ---------------------------------

         The Company covenants and agrees for the benefit of each series of
Senior Notes that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Senior Notes of that series in accordance with the
terms of the Senior Notes and this Indenture.

SECTION 1002      MAINTENANCE OF OFFICE OR AGENCY

Senior Notes of each series may be presented or surrendered for payment, where

exchange and where notices and demands to or upon the Company in respect of the
Senior Notes of that series and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and any change in the

Notes or shall fail to furnish the Trustee with the address thereof, such
presentations and surrenders of Senior Notes of that series may be made and
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive

foregoing purposes.

SECTION 1003      MONEY FOR SENIOR NOTES PAYMENTS TO BE HELD IN TRUST
                  ---------------------------------------------------

         If the Company or one of its Affiliates shall at any time act as its
own Paying Agent with respect to any series of Senior Notes, it will, on or
before each due date of the principal of (and premium, if any) or interest on
any of the Senior Notes of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal
(and premium, if any) 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 for any
series of Senior Notes, it will, prior to each due date of the principal of (and
premium, if any) or interest on any Senior Notes of that series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

                                       45

         The Company will cause each Paying Agent for any series of Senior Notes
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

                  (1)      hold all sums held by it for the payment of the
principal of (and premium, if any) or interest on Senior Notes of that series in
trust for the benefit of the Persons entitled thereto until such sums shall be
paid to such Persons or otherwise disposed of as herein provided;

                  (2)      give the Trustee notice of any default by the Company
(or any other obligor upon the Senior Notes of that series) in the making of any
payment of principal of (and premium, if any) or interest on the Senior Notes of
that series; and

                  (3)      at any time during the continuance of any such
default, upon the written request of the Trustee, forthwith pay to the Trustee
all sums so held in trust by such Paying Agent.

         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 trusts 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 (and premium, if
any) or interest on any Senior Note of any series and remaining unclaimed for
two years after such principal (and premium, if any) 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 Senior
Note 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 of general
circulation in New York City 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, any unclaimed balance of such money then remaining
will be repaid to the Company.

SECTION 1004      CORPORATE EXISTENCE
                 --------------------

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the rights (charter and statutory) and franchises of the Company;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company, and that the loss thereof is not disadvantageous in any material
respect to the Holders.

financial officer or the principal accounting officer of the Company, as to his

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 1004 with respect to the
Senior Notes of any series if before the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Senior Notes of such
series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

SECTION 1102      ELECTION TO REDEEM; NOTICE TO TRUSTEE
                  -------------------------------------

         The election of the Company to redeem any Senior Notes shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of all of the Senior Notes of any series, the Company shall, at
least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date. In case of any redemption at the election of

at least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of Senior Notes of
such series to be redeemed. In the case of any redemption of Senior Notes (i)
prior to the expiration of any restriction on such redemption provided in the
terms of such Senior Notes or elsewhere in this Indenture, or (ii) pursuant to
an election of the Company which is subject to a condition specified in the
terms of such Senior Notes, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction or condition.

SECTION 1103      SELECTION BY TRUSTEE OF SENIOR NOTES TO BE REDEEMED
                  ---------------------------------------------------

         If the Senior Notes are registered in the name of only one Holder, any
partial redemptions shall be pro rata. If the Senior Notes are held in
definitive form by more than one Holder and if less than all the Senior Notes of
any series are to be redeemed, the particular Senior Notes to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Senior Notes of such series not previously called for
redemption, by lot or other such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Senior Notes of that series or
any integral multiple thereof) of the principal amount of Senior Notes of such
series of a denomination larger than the minimum authorized denomination for
Senior Notes of that series.

         The Trustee shall promptly notify the Company in writing of the Senior
Notes selected for redemption and, in the case of any Senior Notes selected for
partial redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise

series are to be redeemed, the identification (and, in the case of partial
redemption, the principal amounts) of the particular Senior Notes to be
redeemed,

                  (4)      that on the Redemption Date the Redemption Price will
become due and payable upon each such Senior Note to be redeemed and, if
applicable, that interest thereon will cease to accrue on and after said date,

be surrendered for payment of the Redemption Price,

                  (6)      the CUSIP numbers; and

                  (7)      that the redemption is for a sinking fund, if such

the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         The Company shall give the Trustee prompt notice of the amount of any
Redemption Price that is subject to calculation, promptly after the calculation
thereof.

SECTION 1105  DEPOSIT OF REDEMPTION PRICE
              ---------------------------

         Except as otherwise provided in a supplemental indenture pursuant to

its own Paying Agent, segregate and hold in trust as provided in Section 1003)

interest, if any, on all the Senior Notes which are to be redeemed on that date.

         Notice of redemption having been given as aforesaid, the Senior Notes
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified together with any accrued interest thereon,
and from and after such date (unless the Company shall default in the payment of
the Redemption Price and accrued interest) such Senior Notes shall cease to bear
interest. Upon surrender of any such Senior Note for redemption in accordance
with such notice, such Senior Note shall be paid by the Company at the
Redemption Price, together with accrued interest, if any; provided, however,
that, except as otherwise provided in a supplemental indenture pursuant to
Section 301, installments of interest on Senior Notes whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Senior Notes, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 305.

                                       49

surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Senior Note.

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

                  Any Senior Note that is to be redeemed only in part shall be

or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Senior Note without service charge, a new Senior Note of the same series,
Stated Maturity and original issue date of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Senior Note so surrendered.

Certificate specifying the amount of the next ensuing sinking fund payment for

which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Senior Notes of that series
pursuant to Section 1202 and stating the basis for such credit and that such
Senior Notes have not previously been so credited and will also deliver to the
