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 so
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.

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

         Section 1.04.  Directions of Certificateholders.  (a)  Any direction,
consent, request, demand, authorization, notice, waiver or other action provided
by this Agreement to be given or taken by Certificateholders (a "Direction") may

tenor signed by such Certificateholders in person or by an agent or proxy duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required pursuant to this
   19

                                      13

   
Agreement, to the Company or the Indenture Trustee. Proof of execution of any
such instrument or of a writing appointing any such agent or proxy shall be
sufficient for any purpose of this Agreement and conclusive in favor of the
Trustee, the Company and the Indenture Trustee, if made in the manner provided
in this Section.
    
              
         (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the certificate of any notary public or
other officer of any jurisdiction authorized to take acknowledgments of deeds or
administer oaths that the Person executing such instrument acknowledged to him
the execution thereof, or by an affidavit of a witness to such execution sworn
to before any such notary or such other officer and where such execution is by
an officer of a corporation or association or a member of a partnership, on
behalf of such corporation, association or partnership, such certificate or
affidavit shall also constitute sufficient proof of his authority.  The fact and
date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other reasonable manner
which the Trustee deems sufficient.

         (c)  In determining whether the Certificateholders of the requisite
Fractional Undivided Interests of Certificates Outstanding have given any
Direction under this Agreement, Certificates owned by the Company or any
Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall be
protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

         (d)  The Company may at its option, by delivery of an Officer's
Certificate to the Trustee, set a record date to determine the
Certificateholders entitled to give any Direction.  Notwithstanding Section
316(c) of the Trust Indenture Act, such record date shall be the record date
specified in such Officer's Certificate, which shall be a date not more than 30
days prior to the first solicitation of Certificateholders in connection
therewith.  If such a record date is fixed, such Direction may be given before
or after such record date, but only the Certificateholders of record at the
close of business on such record date shall be deemed to be Certificateholders
for the purposes of determining whether Certificateholders of the requisite
proportion of Outstanding Certificates have authorized or agreed or consented to
such Direction, and for that purpose the Outstanding Certificates shall be
computed as of such record date; provided that no such Direction by the
Certificateholders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Agreement not later than one
year after such record date.
   20

                                      14

         (e)  Any Direction by the Holder of any Certificate shall bind the 
Holder of every Certificate issued upon the transfer thereof or in exchange
therefor or in lieu thereof, whether or not notation of such Direction is made
upon such Certificate.
        
         (f)  Except as otherwise provided in Section 1.04(c), Certificates 
owned by or pledged to any Person shall have an equal and proportionate benefit
under the provisions of this Agreement, without preference, priority, or
distinction as among all of the Certificates.

or this Agreement, that each of the Company and the Trustee determines in its
discretion to be necessary or desirable for such purposes, as long as such
action does not adversely affect in any material respect the interests of the
Certificateholders.

                              THE CERTIFICATES

         Section 3.01.  Title, Form, Denomination and Execution of Certificates.
(a)  The Certificates shall be known as the "    % Pass Through Certificates
Series I" of the Trust.  Each Certificate will represent a fractional undivided
interest in the Assigned Trust Property and shall be substantially in the form
set forth as Exhibit A hereto, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Agreement and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with the rules of any securities exchange or as may, consistently herewith, be
determined by the officers executing such Certificates, as evidenced by their
execution of the Certificates.  Any portion of the text of any Certificate may
be set forth on the reverse thereof, with an appropriate reference thereto on
the face of the Certificate.

         (b) The Certificates shall be issued only in fully registered form
without coupons and only in denominations of $[250,000] or integral multiples
of $1,000 in excess thereof.  Each Certificate shall be dated the date of its

shall not at any time exceed $[150,000,000].

         (c) Certificates offered and sold to QIBs and to Institutional
Accredited Investors in reliance on Rule 3a-7 shall be issued in the form of a
single permanent global Certificate in registered form, substantially in the
form set forth as Exhibit A hereto (the "Global Certificate"), duly executed
and authenticated by the Trustee as hereinafter provided.  The Global
Certificate will be registered in the name of a nominee for the Depositary and
deposited with the Trustee, as custodian for the Depositary.  The aggregate
principal amount of the Global Certificate may from time to time be increased
or decreased by adjustments made on the records of the Depositary or its
nominee, or of the Trustee, as custodian for the Depositary or its nominee, as
hereinafter provided.

         (d) Definitive Certificates shall be in registered form and shall be
typed, printed, lithographed or engraved or produced by any combination of
these methods or may be produced in any other manner, all as determined by the

         Section 3.02.  Restrictive Legends.  (a)  The Global Certificate shall
bear the following legend (the "Permanent Legend") on the face thereof:

         THIS CERTIFICATE MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN
    THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE CERTIFICATEHOLDER
    (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
    DEFINED IN RULE 144A UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED
    (THE "SECURITIES ACT")) OR (B) IT IS AN INSTITUTIONAL "ACCREDITED
    INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) OF REGULATION D
    UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL ACCREDITED INVESTOR"), (2)
    AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE
    EXCEPT (A) TO THE COMPANY, (B) TO A QUALIFIED INSTITUTIONAL BUYER, OR (C)
    TO AN INSTITUTIONAL ACCREDITED INVESTOR, AND (3) AGREES THAT IT WILL
    DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS TRANSFERRED A NOTICE
    SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.
    
         (b) The Global Certificate shall also bear the following legend on the
face thereof:

    UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
    THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE
    TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
    AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE IS REGISTERED
    IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN
    AUTHORIZED  REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE
    & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
    REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
    VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
    REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.
    
    TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN
    WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR
    SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
    CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
    RESTRICTIONS SET FORTH IN SECTIONS 3.05 AND 3.06 OF THE PASS THROUGH
    TRUST AGREEMENT REFERRED TO HEREIN.
   27

                                     21

         Section 3.03.  Authentication of Certificates.  (a)  The Trustee shall
duly execute, authenticate and deliver Certificates in authorized denominations
equalling in the aggregate the aggregate principal amount of the X-TRAS to be
purchased by the Trustee pursuant to the Purchase Agreement and evidencing the
entire ownership of the Trust.

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

         Section 3.04.  Transfer and Exchange.  (a)  The Trustee shall cause to
be kept at the office or agency to be maintained by it in accordance with the
provisions of Section 7.12 of this Agreement a register (the "Register") for
the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor of a sum sufficient to cover any transfer
tax or similar governmental charge payable in connection therewith (other than
any such transfer taxes or other similar governmental charges payable upon
exchanges pursuant to Section 3.10 or 9.07).
   28

                                     22

         Section 3.05.  Book-Entry Provisions for the Global Certificate.  (a)
Members of, or participants in, the Depositary ("Agent Members") shall have no
rights under this Agreement with respect to the Global Certificate held on
their behalf by the Depositary, or the Trustee as its custodian, and the
Depositary may be treated by the Trustee and any agent of the Trustee as the
absolute owner of such Global Certificate for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Trustee or any
agent of the Trustee from giving effect to any written certification, proxy or
other authorization furnished by the Depositary or shall impair, as between the
Depositary and its Agent Members, the operation of customary practices
governing the exercise of the rights of a holder of any Certificate.  Upon the
issuance of any Global Certificate, the Registrar or its duly appointed agent
shall record a nominee of the Depositary as the registered holder of such
Global Certificate.

         (b) Transfers of any Global Certificate shall be limited to transfers
of such Global Certificate in whole, but not in part, to nominees of the
Depositary, its successor or such successor's nominees.  Beneficial interests
in the Global Certificate may be transferred in accordance with the rules and
procedures of the Depositary and the provisions of Section 3.06.  Beneficial
interests in the Global Certificate shall be delivered to all beneficial owners
in the form of definitive Certificates if (i) the Depositary notifies the
Trustee that it is unwilling or unable to continue as Depositary for the Global
Certificate and a successor depositary is not appointed by the Trustee within
90 days of such notice or (ii) an Event of Default has occurred and is
continuing and the Registrar has received a request from the Depositary to
issue definitive Certificates.
        
         (c) In connection with the transfer of the entire Global Certificate to
the beneficial owners thereof pursuant to paragraph (b) of this Section 3.05,
the Global Certificate shall be deemed to be surrendered to the Trustee for
cancellation, and the Trustee shall execute, authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in the Global Certificate an equal aggregate principal amount of
definitive Certificates of authorized denominations.

         (d) Any Physical Certificate delivered in exchange for an interest in
the Global Certificate pursuant to paragraph (b) of this Section 3.05 shall,
except as otherwise provided by paragraph (f) of Section 3.06, bear the
Permanent Legend.

         (e) The registered holder of the Global Certificate may grant proxies
and otherwise authorize any Person, including Agent Members and Persons that
may hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Agreement or the Certificates.

         Section 3.06.  Special Transfer Provisions.  The following provisions
shall apply to the Certificates:
   29

                                     23

         (a) Transfers to Non-QIB Institutional Accredited Investors.  The
Registrar shall register the transfer of any Certificate to any Institutional
Accredited Investor.

         (b) Transfers to QIBs.  The Registrar shall register the transfer of
any Certificate to any QIB.

   
         (c) Permanent Legend.  Upon the transfer, exchange or replacement of
Certificates bearing the Permanent Legend, the Registrar shall deliver only
Certificates that bear the Permanent Legend unless there is delivered to the
Registrar an Opinion of Counsel to the effect that neither such legend nor the
related restrictions on transfer are required in order to maintain compliance
with the provisions of the 1940 Act.
    

         (d) General.  By its acceptance of any Certificate bearing the
Permanent Legend, each Holder of such a Certificate acknowledges the
restrictions on transfer of such Certificate set forth in this Agreement and
agrees that it will transfer such Certificate only as provided in this
Agreement.  The Registrar shall not register a transfer of any Certificate
unless such transfer complies with the restrictions on transfer of such
Certificate set forth in this Agreement.  In connection with any transfer of
Certificates, each Certificateholder agrees by its acceptance of the
Certificates to furnish the Registrar or the Trustee such certifications or
other information as either of them may reasonably require; provided that the
Registrar shall not be required to determine the sufficiency of any such
certifications, legal opinions or other information.

         Until such time as no Certificates remain Outstanding, the Registrar
shall retain copies of all letters, notices and other written communications
received pursuant to Section 3.05 or this Section 3.06.  The Trustee, if not
the Registrar at such time, shall have the right to inspect and make copies of
all such letters, notices or other written communications at any reasonable
time upon the giving of reasonable written notice to the Registrar.

   
         Section 3.07.  Mutilated, Destroyed, Lost or Stolen Certificates.  If
(a) any mutilated Certificate is surrendered to the Registrar or the Registrar
receives evidence to its satisfaction of the mutilation, destruction, loss or
theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them and any Paying Agent harmless, then, in the absence of notice to
the Registrar or the Trustee that such destroyed, lost or stolen Certificate
has been acquired by a bona fide purchaser, and provided that the requirements
of Section 8-405 of the Uniform Commercial Code in effect in any applicable
jurisdiction are met, then, upon payment by the Certificateholder of any
applicable expenses, the Trustee shall execute, authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate or Certificates, in authorized denominations and
of like Fractional Undivided Interest and bearing a number not
contemporaneously outstanding.
    

   30

                                     24

         In connection with the issuance of any new Certificate under this
Section 3.07, the Trustee 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 and the
Registrar) connected therewith.

         Any duplicate Certificate issued pursuant to this Section 3.07 shall
constitute conclusive evidence of the appropriate Fractional Undivided Interest
in the Trust, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

         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 Certificates.

         Section 3.08.  Persons Deemed Owners.  Prior to due presentment of a   
Certificate for registration of transfer, the Trustee, the Registrar and any
Paying Agent may treat the Person in whose name any Certificate is registered
(as of the day of determination) as the owner of such Certificate for the
purpose of receiving distributions pursuant to Article IV and for all other
purposes whatsoever, and none of the Trustee, the Registrar or any Paying Agent
shall be affected by any notice to the contrary.

         Section 3.09.  Cancellation.  All Certificates surrendered for payment
or transfer or exchange shall, if surrendered to the Trustee or any agent of
the Trustee other than the Registrar, be delivered to the Registrar for
cancellation and shall promptly be cancelled by it.  No Certificates shall be
authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

   
        Section 3.10.  Temporary Certificates.  Until definitive Certificates
are ready for delivery, the Trustee shall authenticate temporary Certificates.
Temporary Certificates shall be substantially in the form of definitive
Certificates but may have insertions, substitutions, omissions and other
variations determined to be appropriate by the officers executing the temporary
Certificates, as evidenced by their execution of such temporary Certificates.
If temporary Certificates are issued, the Trustee will cause definitive
Certificates to be prepared without unreasonable delay.  After the preparation
of definitive Certificates, the temporary Certificates shall be exchangeable
for definitive Certificates upon surrender of the temporary Certificates at the
office or agency of the Trustee designated for such purpose pursuant to Section
7.12, without charge to the Certificateholder.  Upon surrender for cancellation
of any one or more temporary Certificates, the Trustee shall execute,
authenticate and deliver in exchange therefor a like face amount of definitive
    

   31

                                     25

Certificates of authorized denominations.  Until so exchanged, the temporary
Certificates shall be entitled to the same benefits under this Agreement as
definitive Certificates.

         Section 3.11.  Limitation of Liability for Payments.  All payments and
distributions made to Certificateholders shall be made only from the Assigned
Trust Property and only to the extent that the Trustee shall have sufficient
income or proceeds from the Assigned Trust Property to make such payments in
accordance with the terms of Article IV of this Agreement.  Each
Certificateholder, by its acceptance of a Certificate, agrees that it will look
solely to the income and proceeds from the Assigned Trust Property for any
payment or distribution due to such Certificateholder pursuant to the terms of
this Agreement and that it will not have any recourse to the Company, the
Trustee or the Indenture Trustee except as otherwise expressly provided.
        
         The Company is a party to this Agreement solely for purposes of meeting
the requirements of the Trust Indenture Act, and therefore shall not have any
right, obligation or liability hereunder (except as otherwise expressly
provided herein).

                        DISTRIBUTIONS; STATEMENTS TO
           CERTIFICATEHOLDERS; PAYMENTS TO EXTENSION OPTION BUYER

   
         Section 4.01.  Certificate Account, Special Payments Account and ISDA
Payment Account .  (a)  The Trustee shall establish and maintain on behalf of
the Certificateholders a Certificate Account as one or more
non-interest-bearing accounts.  The Trustee shall hold the Certificate Account
in trust for the benefit of the Certificateholders, and shall make or permit
withdrawals therefrom only as provided in this Agreement.  On each day when a
Scheduled Payment is made to the Trustee under the Indenture, the Trustee upon
receipt thereof shall immediately deposit the aggregate amount of such
Scheduled Payment in the Certificate Account.
    

         (b) The Trustee shall establish and maintain on behalf of the  
Certificateholders a Special Payments Account as one or more accounts, which
shall be non-interest bearing except as provided in Section 4.04.  The Trustee
shall hold the Special Payments Account in trust for the benefit of the
Certificateholders and shall make or permit withdrawals therefrom only as
provided in this Agreement.  On each day when one or more Special Payments are
made to the Trustee, the Trustee, upon receipt thereof, shall immediately
deposit the aggregate amount of such Special Payments in the Special Payments
Account.
   32

                                     26

         (c) The Trustee shall present to the Indenture Trustee the X-TRAS on
the date of their stated final maturity or, in the case of any X-TRAS which are
to be redeemed in whole pursuant to the Indenture, on the applicable redemption
date under such Indenture.

   
         (d) The Trustee shall establish and maintain on behalf of the Extension
Option Buyer an ISDA Payment Account as one or more accounts, which shall be
non-interest bearing.  The Trustee shall hold the ISDA Payment Account in trust
for the benefit of the Extension Option Buyer and shall make withdrawals
therefrom as provided in the ISDA Master Agreement.  On each day when an ISDA
Payment is made to the Trustee by the Company pursuant to the Indenture, the
Trustee, upon receipt thereof, shall immediately deposit such ISDA Payment in
the ISDA Payment Account.
    
        
         Section 4.02.  Distributions from Certificate Account and Special
Payments Account.  (a)  On each Regular Distribution Date, the Trustee shall
distribute out of the Certificate Account to the Certificateholders all
Scheduled Payments the receipt of which is confirmed by the Trustee on such
date.  There shall be so distributed to each Certificateholder of record on the
Record Date with respect to such Regular Distribution Date (other than as
provided in Section 11.01 concerning the final distribution) by check mailed to
such Certificateholder, at the address appearing in the Register, such
Certificateholder's pro rata share (based on the Fractional Undivided Interest
in the Assigned Trust Property held by such Certificateholder) of the total
amount in the Certificate Account, except that, with respect to Certificates
registered on the Record Date in the name of the nominee of the Depositary
(initially, such nominee to be Cede & Co.), such distribution shall be made by
wire transfer in immediately available funds to the account designated by such
nominee.  If a Scheduled Payment is not received by the Trustee on the Register
Distribution Date but is received within [five] Business Days thereafter, it
will be distributed on the date so received by the Trustee to such holders of
record.  If it is received after such [five] day period, it will be treated as
a Special Payment and distributed as described in paragraph (b) below.

   
        (b) With respect to any Special Payment made under clause (i) of the
definition thereof (to the extent redemption of less than all of the X-TRAS is
made), the Trustee shall select, in such a manner as it shall deem appropriate
and fair, the particular Certificates or portions thereof representing
beneficial ownership of the X-TRAS to be redeemed.  Notice of redemption shall
be given by mail not less than 20 nor more than 60 days prior to the date fixed
for redemption of the X-TRAS to the Certificateholders whose Certificates
represent beneficial ownership of the X-TRAS to be redeemed.  Upon a redemption
of less than all of the X-TRAS, Certificates representing beneficial ownership
of the X-TRAS selected for redemption will be required to be presented to the
Trustee for cancellation.  Upon such presentation, all payments of principal
of, Applicable Premium, and interest on the X-TRAS paid by the Company to the
Trust will be paid to the holders of such Certificates.  With respect to any
Special Payment made under clause (ii) or (iii) of the 
    

   33

                                     27

   
definition thereof, there shall be paid to each Certificateholder who has duly
presented for cancellation and not withdrawn its Certificates in compliance
with the provisions of Sections 5.03 and 5.04 an amount equal to the aggregate
purchase price applicable to the X-TRAS beneficially owned by such
Certificateholder in respect of which it has tendered its Certificates.  With
respect to any Special Payment made under clauses (i) (to the extent of a
redemption of all of the X-TRAS), (ii) and (iv) of the definition thereof, the
entire amount of such Special Payment deposited in the Special Payments Account
pursuant to Section 4.01(b) will be distributed on, in the case of an early
redemption of all of the X-TRAS, the date of such early redemption, which shall
be a Business Day, and otherwise 20 days after the Trustee has confirmed
receipt of the funds for such Special Payment (or the next Business Day after
such 20th day if such date is not a Business Day).  With respect to any such
Special Payment, there shall be distributed to each Certificateholder of record
on the Record Date with respect to such Special Distribution Date (other than
as provided in Section 11.01 concerning the final distribution) by check mailed
to such Certificateholder, at the address appearing in the Register, such
Certificateholder's pro rata share (based on the Fractional Undivided Interest
in the Trust held by such Certificateholder) of the total amount in the Special
Payments Account on account of such Special Payment, except that, with respect
to Certificates registered on the Record Date in the name of the nominee of the
Depositary (initially, such nominee to be Cede & Co.), such distribution shall
be made by wire transfer in immediately available funds to the account
designated by such nominee.  The Trustee will mail notice to the
Certificateholders not less than 20 days prior to the Special Distribution Date
on which any Special Payment is scheduled to be distributed by the Trustee
stating such anticipated Special Distribution Date.  Each distribution of a
Special Payment, other than the Final Distribution, on a Special Distribution
Date will be made by the Trustee to Certificateholders of record on the 15th
day next preceding such Special Distribution Date.
    
        
         (c) The Trustee shall, at the expense of the Company, cause notice of
each Special Payment to be mailed to each Certificateholder at his address as
it appears in the Register.  In the event of redemption or purchase of X-TRAS
held in the Trust, such notice shall be mailed not less than 20 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or purchase.  In the case of any other Special Payments, such
notice shall be mailed as soon as practicable after the Trustee has confirmed
that it has received funds for such Special Payment, stating the Special
Distribution Date for such Special Payment which shall occur not less than 20
days after the date of such notice and as soon as practicable thereafter.
Notices mailed by the Trustee shall set forth:

         (i) the Special Distribution Date and the Record Date therefor
    (except as otherwise provided in Section 11.01),
    
         (ii) the amount of the Special Payment for each $1,000 face amount
    Certificate (taking into account any payment to be made by the Company
    pursuant to 
   34

                                     28


   
    Section 2.03(b)) and the amount thereof constituting principal, premium, if
    any, and interest,
    
        
         (iii) the reason for the Special Payment, and
    
         (iv) if the Special Distribution Date is the same date as a Regular
    Distribution Date, the total amount to be received on such date for each
    $1,000 face amount Certificate.
    
If the amount of premium, if any, payable upon the redemption or
purchase of an X-TRAS has not been calculated at the time that the Trustee
mails notice of a Special Payment, it shall be sufficient if the notice sets
forth the other amounts to be distributed and states that any premium received
will also be distributed.

         If any redemption of the X-TRAS held in the Trust is cancelled, the
Trustee, as soon as possible after learning thereof, shall cause notice thereof
to be mailed to each Certificateholder at its address as it appears on the
Register.

         Section 4.03.  Statements to Certificateholders.  (a)  On each
Distribution Date, the Trustee will include with each distribution to
Certificateholders of a Scheduled Payment or Special Payment, as the case may
be, a statement setting forth the following information (per $1,000 face amount
Certificate as to (i) and (ii) below):

         (i) the amount of such distribution allocable to principal and the
    amount allocable to premium, if any; and
    
         (ii) the amount of such distribution allocable to interest.
    
         With respect to the Certificates registered in the name of Cede & Co.,
as nominee for the Depositary, on the Record Date prior to each Distribution
Date, the Trustee will request from the Depositary a Securities Position
Listing setting forth the names of all Agent Members reflected on the
Depositary's books as holding interests in the Certificates on such Record
Date.  On each Distribution Date, the Trustee will mail to each such Agent
Member the statement described above and will make available additional copies
as requested by such Agent Member for forwarding to holders of interests in the
Certificates.

         (b) Within a reasonable period of time after the end of each calendar
year but not later than the latest date permitted by law, the Trustee shall
furnish to each Person who at any time during such calendar year was a
Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i) and (a)(ii) above with respect to the
Trust for such calendar year or, in the event such Person was a
Certificateholder of record during a portion of such calendar year, for such
portion of such 
   35
                                      29

   
year, and such other items as are readily available to the Trustee and which a
Certificateholder shall reasonably request as necessary for the purpose of such
Certificateholder's preparation of its federal income tax returns.  Such
statement and such other items shall be prepared on the basis of information
supplied to the Trustee by the Agent Members and shall be delivered by the
Trustee to such Agent Members to be available for forwarding by such Agent
Members to the holders of interests in the Certificates in the manner described
in Section 4.03(a).
    
        
         Section 4.04.  Investment of Special Payment Moneys.  Any money
received by the Trustee pursuant to Section 4.01(b) representing a Special
Payment which is not to be promptly distributed shall, to the extent
practicable, be invested in Permitted Investments by the Trustee pending
distribution of such Special Payment pursuant to Section 4.02.  Any investment
made pursuant to this Section 4.04 shall be in such Permitted Investments
having maturities not later than the date that such moneys are required to be
used to make the payment required under Section 4.02 on the applicable Special
Distribution Date and the Trustee shall hold any such Permitted Investments
until maturity.  The Trustee shall have no liability with respect to any
investment made pursuant to this Section 4.04, other than by reason of the
willful misconduct or negligence of the Trustee.  All income and earnings from
such investments shall be distributed on such Special Distribution Date as part
of such Special Payment.

   
         Section 4.05.  Payments from ISDA Payment Account.  With respect to an
ISDA Payment received by the Trust on the Final Distribution Date and deposited
in the ISDA Payment Account, the Trustee shall withdraw such ISDA Payment from
the ISDA Payment Account and pay such amount by wire transfer on the Final
Distribution Date to the Extension Option Buyer to an account designated by it
pursuant to the ISDA Master Agreement.  With respect to all other ISDA Payments

Payment from the ISDA Payment Account and pay such amount by wire transfer to
the Extension Option Buyer to the account designated by it pursuant to the ISDA
Master Agreement on the following dates:  (i) in the event of an ISDA Payment

                                 THE COMPANY

         Section 5.01.  Maintenance of Corporate Existence.  The Company, at its
own cost and expense, will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence, rights and
franchises, except as otherwise specifically permitted in Section 5.02;
provided, however, that the Company shall not be required to preserve any right
or franchise if the Company shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company.

   
         Section 5.02.  Covenant of the Company Not to Merger, Consolidate, Sell
or Convey Property Except Under Certain Conditions.  Nothing contained in this
Agreement or in any of the Certificates shall prevent any consolidation of the
Company with, or merger of the Company into, any other corporation or
corporations (whether or not affiliated with the Company), or successive
consolidations or mergers to which the Company or its successor or successors
shall be a party or parties, shall prevent any sale, lease or conveyance of the
property of the Company as an entirety or substantially as an entirety, shall
prevent any consolidation of any Person with, or the merger of any Person into,
the Company or shall prevent any sale, lease or conveyance of the property of
any Person as an entirety or substantially as an entirety to the Company;
provided that, and the Company hereby covenants and agrees, upon any such
consolidation, merger, sale, lease or conveyance, the due and punctual
performance and observance of each covenant and condition of this Agreement to
be performed or observed by the Company, shall be expressly assumed, by an
agreement in form and substance reasonably satisfactory to the Trustee, duly
authorized, executed and delivered to the Trustee by the corporation formed by
such consolidation, or into which the Company shall have been merged, or which
shall have acquired such property; provided further that the corporation formed
by such consolidation or into which the Company merged or the Person which
acquired by conveyance or sale, or which leases, the properties and assets of
the Company as an entirety or substantially as an entirety shall be a
corporation organized and existing under the laws of the United States of
America, any State thereof or the District of Columbia; provided further that
immediately after giving effect to such transaction, and treating any
indebtedness which becomes an obligation of the Company or a Subsidiary as a
result of such transaction as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of Default,
shall have happened and be continuing.
    

   
         In case of any consolidation, merger, sale, lease or conveyance
referred to in, and in accordance with, Section 5.02, and following such an
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it
had been named herein as Company.
    

   37

                                      31

   
         The Trustee, subject to the provisions of Sections 7.1 and 7.3, may
receive an Opinion of Counsel from the Company as conclusive evidence that any
such consolidation, merger, sale, lease or conveyance, and any such assumption,
and any such liquidation or dissolution, complies with the applicable
provisions of this Agreement and that all conditions precedent herein provided
for relating to such transactions have been complied with.
    

   
         Section 5.03.   Change in Control.  Upon the occurrence of a Change in
Control (the effective date of such Change in Control being the "Change in
Control Date"), each Certificateholder shall have the right to direct the
Trustee to require the Company to repurchase (a "Required Repurchase") all or
any part of the X-TRAS beneficially owned by such Certificateholder at a
repurchase price payable in cash equal to 101% of the principal amount of such
X-TRAS together with accrued interest to the Change in Control Purchase Date
(as defined below) (the "Change in Control Purchase Price"), plus (in the
aggregate with all other beneficially owned X-TRAS repurchased pursuant to this
Section 5.03) the ISDA Amount, if any, as of the Change in Control Purchase
Date as determined by the Extension Option Buyer and notified to the Company,
the Indenture Trustee and the Trustee by 10:00 a.m., New York City time, on
such date.
    

         (a)   Within 30 days following the Change in Control Date, the Company
shall mail a notice (the "Required Repurchase Notice") to each
Certificateholder with copies to the Indenture Trustee, the Trust and the
Extension Option Buyer stating:

         (i)   that a Change in Control has occurred and that such
    Certificateholder has the right to direct the Trustee to require the
    Company to repurchase all or any part of the X-TRAS beneficially owned by
    such Certificateholder at the Change in Control Purchase Price upon
    presentation for cancellation of the related Certificates;
    
         (ii)  the Change in Control Purchase Price;
    
         (iii) the date on which any Required Repurchase shall be made (which
    shall be no earlier than 60 days nor later than 90 days from the date
    such notice is mailed) (the "Change in Control Purchase Date");
    
         (iv)  the name and address of the Paying Agent; and
    
         (v)   the procedures that Certificateholders must follow to cause the
    X-TRAS beneficially owned by them to be repurchased, which shall be
    consistent with this Section and the Indenture.
     
         (b)   Certificateholders electing to have X-TRAS beneficially owned by
them repurchased must deliver a written notice (the "Change in Control Purchase
Notice") to the X-TRAS Paying Agent (initially the Indenture Trustee) at its
corporate trust office in Detroit,     
   38

                                     32

   
Michigan, or any other office of the X-TRAS Paying Agent maintained for such
purposes, not later than 30 days prior to the Change in Control Purchase Date. 
The Change in Control Purchase Notice shall state:  (i) the portion of the
principal amount of any X-TRAS beneficially owned by the Certificateholder to
be repurchased, which portion must be $1,000 or an integral multiple thereof;
(ii) that such X-TRAS are to be repurchased by the Company pursuant to the
change in control provisions of the Indenture and the Trust Agreement; and
(iii) unless the Certificates evidencing beneficial ownership of the X-TRAS to
be repurchased are represented by one or more Global Certificates, the
certificate numbers of the Certificates to be delivered by the
Certificateholder thereof the X-TRAS in respect of which are to be repurchased
by the Company.  Any Change in Control Purchase Notice may be withdrawn by the
Certificateholder by a written notice of withdrawal delivered to the Paying
Agent not later than three Business Days prior to the Change in Control
Purchase Date.  The notice of withdrawal shall state the principal amount of
beneficially owned X-TRAS as to which the withdrawal notice relates and the
principal amount of such beneficially owned X-TRAS, if any, which remains
subject to a Change in Control Purchase Notice.
    
        
   
         If Certificates are represented by a Global Note (as described in
Section 3.05), the Depositary or its nominee will be the Holder of such
Certificates and therefore will be the only entity that may elect a Required
Repurchase of the beneficially owned X-TRAS in respect of such Certificates. 
To obtain repayment pursuant to this Section 5.03 with respect to the X-TRAS in
respect of such Certificates, the beneficial owner of such Certificates must
provide to the broker or other entity through which it holds the beneficial
interest in such Certificates (i) the Change in Control Purchase Notice signed
by such beneficial owner, and such signature must be guaranteed by a member
firm of a registered national securities exchange or of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
having an office or correspondent in the United States, and (ii) instructions
to such broker or other entity to notify the Depositary of such beneficial
owner's desire to obtain repayment pursuant to this Section 5.03.  Such broker
or other entity will provide to the Paying Agent (i) the Change in Control
Purchase Notice received from such beneficial owner and (ii) a certificate
satisfactory to the X-TRA Paying Agent from such broker or other entity stating
that it represents such beneficial owner.  Such broker or other entity will be
responsible for disbursing any payments it receives pursuant to this Section
3.01 to such beneficial owner.
    

         (c)   Payment to a Certificateholder of the Change in Control Purchase
Price for X-TRAS beneficially owned by it for which a Change in Control
Purchase Notice has been delivered and not withdrawn is conditioned (except in
the case of Certificates represented by one or more Global Certificates) upon
presentation for cancellation of the Certificates in respect of such X-TRAS
(together with necessary endorsements) to the X-TRAS Paying Agent at its office
in Detroit, Michigan, or any other office of the X-TRAS Paying Agent maintained
for such purpose, at any time (whether prior to, on or after the Change in
Control Purchase Date) after the delivery of such Change in Control Purchase
   39

                                     33

   
Notice.  Payment of the Change in Control Purchase Price for the Certificates
in respect of such X-TRAS will be made promptly following the later of the
Change in Control Purchase Date or the time of presentation for cancellation of
such Certificates.  If the X-TRAS Paying Agent holds, in accordance with the
terms of the Indenture, money sufficient to pay the Change in Control Purchase
Price of the Certificates in respect of such X-TRAS on the Business Day
following the Change in Control Purchase Date, then, on and after such date,
interest will cease accruing on such X-TRAS, whether or not such Certificates
are delivered to the X-TRAS Paying Agent, and all other rights of the
Certificateholder shall terminate (other than the right to receive the Change
in Control Purchase Price upon delivery of the Certificates in respect of such
X-TRAS).
    

         (d)   The Company shall comply with the provisions of Regulation 14E 
and any other tender offer rules under the Exchange Act which may then be
applicable in connection with any offer by the Company to repurchase X-TRAS
beneficially owned by a Certificateholder at the option of Certificateholder
upon a Change in Control.

         (e)   No beneficially owned X-TRAS may be repurchased by the Company 
as a result of a Change in Control if there has occurred and is continuing an
Event of Default (other than a default in the Payment of the Change in Control
Purchase Price with respect to the X-TRAS).
        
         (f)   Upon receipt by the Trustee of the ISDA Amount payable pursuant 
to the first sentence of this Section 5.03, such amount shall be deposited in 
the ISDA Payment Account and thereafter promptly paid to the Extension Option
Buyer.

   
         Section 5.04   Excess Proceeds of Asset Sales.  In the event that the
Company is required under Section 4.05 of the Indenture to make an offer to
purchase from holders of X-TRAS on a pro rata basis an aggregate principal
amount of X-TRAS equal to the Excess Proceeds resulting from an Asset Sale,
each Certificateholder shall have the right to direct the Trustee to require
the Company to repurchase a pro rata portion of the X-TRAS beneficially owned
by such Certificateholder at a repurchase price payable in cash equal to 100%
of the principal amount or portion thereof of X-TRAS to be repurchased together
with accrued and unpaid interest, if any, to the Excess Proceeds Purchase Date
(as defined herein), plus the ISDA Amount, if any, as of the Excess Proceeds
Purchase Date as determined by the Extension Option Buyer as of such date and
notified to the Company, the Indenture Trustee and the Trustee by 10 a.m., New
York City time, on such date.
    
        
   
         (a)   Within 30 days after the end of the Application Period, the
    Company shall mail a notice (the "Excess Proceeds Repurchase Notice") to
    each Holder with copies to the Indenture Trustee, Pass Through Trustee
    and Extension Option Buyer stating:
    

   40

                                     34

   
               (i)   that the Company is making an Excess Proceeds Offer
         pusuant to Section 3.01 of the Sixth Supplemental Indenture;
    
    
               (ii)  the Excess Proceeds Purchase Price;
    
               (iii) the date on which any Exceeds Proceeds Repurchase shall
         be made (which shall be no earlier than 60 days nor later than 90
         days from the date such notice is mailed) (the "Excess Proceeds
         Purchase Date");
    
               (iv)  the name and address of the X-TRAS Paying Agent; and
    
   
               (v)   the procedures that Holders must follow to cause the
         X-TRAS to be repurchased, which shall be consistent with this
         Section and the Indenture.
    
    
   
         (b) Certificateholders electing to have X-TRAS beneficially owned by
    them repurchased must deliver a written notice (the "Excess Proceeds
    Purchase Notice") to the X-TRAS Paying Agent at its corporate trust
    office in Detroit, Michigan, or any other office of the X-TRAS Paying
    Agent maintained for such purposes, not later than 30 days prior to the
    Excess Proceeds Purchase Date.  The Excess Proceeds Purchase Notice shall
    state:  (i) the portion of the principal amount of any beneficially owned
    X-TRAS of the Certificateholder to be repurchased, which portion must be
    $1,000 or an integral multiple thereof; (ii) that such X-TRAS are to be
    repurchased by the Company pursuant to the Exceeds Proceeds Offer
    provisions of the Indenture; and (iii) unless the Certificates evidencing
    beneficial ownership of the X-TRAS  to be repurchased are represented by
    one or more Global Certificates, the certificate numbers of the
    Certificates to be delivered by the Certificateholder thereof for
    repurchase by the Company.  Any Excess Proceeds Purchase Notice may be
    withdrawn by the Certificateholder by a written notice of withdrawal
    delivered to the X-TRAS Paying Agent not later than three Business Days
    prior to the Excess Proceeds Purchase Date.  The notice of withdrawal
    shall state the principal amount of beneficially owned X-TRAS as to which
    the withdrawal notice relates and the principal amount of such beneficially
    owned X-TRAS, if any, which remains subject to a Excess Proceeds Purchase
    Notice.
    
        
         If Certificates are represented by a Global Note (as described in
    Section 3.05), the Depositary or its nominee will be the Holder of such
    Certificates and therefore will be the only entity that may elect an
    Excess Proceeds Repurchase of the beneficially owned X-TRAS in respect of
    such Certificates.  To obtain repayment pursuant to this Section 5.04
    with respect to the X-TRAS in respect of such Certificates, the
    beneficial owner of such Certificates must provide to the broker or other
    entity through which it holds the beneficial interest in such
    Certificates (i) the Excess Proceeds Purchase Notice signed by such
    beneficial owner, and such signature     
   41

                                     35

    must be guaranteed by a member firm of a registered national securities
    exchange or of the National Association of Securities Dealers, Inc. or a
    commercial bank or trust company having an office or correspondent in the
    United States, and (ii) instructions to such broker or other entity to
    notify the Depositary of such beneficial owner's desire to obtain repayment
    pursuant to this Section 5.04.  Such broker or other entity will provide to
    the X-TRAS Paying Agent (i) the Excess Proceeds Purchase Notice received
    from such beneficial owner and (ii) a certificate satisfactory to the
    X-TRAS Paying Agent from such broker or other entity stating that it
    represents such beneficial owner.  Such broker or other entity will be
    responsible for disbursing any payments it receives pursuant to this
    Section 3.01 to such beneficial owner.
        
         (c) Payment to a Certificateholder of the Excess Proceeds Purchase
    Price for beneficially owned X-TRAS for which a Excess Proceeds Purchase
    Notice has been delivered and not withdrawn is conditioned (except in the
    case of Certificates represented by one or more Global Certificates) upon
    presentation for cancellation of the Certificates in respect of such
    X-TRAS (together with necessary endorsements) to the X-TRAS Paying Agent
    at its office in Detroit, Michigan, or any other office of the X-TRAS
    Paying Agent maintained for such purpose, at any time (whether prior to,
    on or after the Excess Proceeds Purchase Date) after the delivery of such
    Excess Proceeds Purchase Notice.  Payment of the Excess Proceeds Purchase
    Price for the Certificates in respect of such X-TRAS will be made
    promptly following the later of the Excess Proceeds Purchase Date or the
    time of delivery of such Certificates.   If the X-TRAS Paying Agent
    holds, in accordance with the terms of the Indenture, money sufficient to
    pay the Excess Proceeds Purchase Price of the Certificates in respect of
    such X-TRAS on the Business Day following the Excess Proceeds Purchase
    Date, then, on and after such date, interest will cease accruing, and all
    other rights of the Holder shall terminate (other than the right to
    receive the Excess Proceeds Purchase Price upon delivery of the X-TRAS).
    
         (d) The Company shall comply with the provisions of Regulation 14E
    and any other tender offer rules under the Exchange Act, which may then
    be applicable in connection with any Excess Proceeds Offer.
    
         (e) Upon receipt by the Trustee of the ISDA Amount payable pursuant
    to the first sentence of this Section 5.04, such amount shall be
    deposited in the ISDA Payment Account and thereafter promptly paid to the
    Extension Option Buyer.

                                     36

                                 ARTICLE VI

                                   DEFAULT

   
         Section 6.01.  Events of Default.  If any Indenture Default under the
Indenture (an "Event of Default") shall occur and be continuing, then, and in
each and every case, so long as such Event of Default shall be continuing, the
Trustee may vote the X-TRAS, and upon the direction of Certificateholders
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in the Assigned Trust Property, the Trustee shall vote, in favor of
directing the Indenture Trustee to declare the unpaid principal amount of the
X-TRAS then outstanding and accrued interest thereon to be due and payable
under, and in accordance with the provisions of, the Indenture.  In addition,
if an Indenture Default shall have occurred and be continuing under the
Indenture, the Trustee may in accordance with the Indenture vote the X-TRAS to
direct the Indenture Trustee regarding the exercise of remedies provided in
Article IV of the Indenture.  Notwithstanding the provisions of Section 4.02,
if in connection with any Event of Default as to which moneys are collected by
the Trustee the amounts paid by the Company are less than the amounts due in
respect of (i) the principal of and interest on the X-TRAS and (ii) the ISDA
Amount, if any, the amounts received by the Trustee will be distributed on a
pro rata basis to the Certificateholders, on the one hand, and the Extension
Option Buyer, on the others; provided that no such distribution shall affect
the rights of the Trustee to demand and receive payment in full of all amounts
due from the  Company.
    

         In addition, after an Event of Default shall have occurred and be
continuing with respect to the X-TRAS, the Trustee may in its discretion, and
upon the direction of the Certificateholders evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Assigned
Trust Property shall, by such officer or agent as it may appoint, sell, convey,
transfer and deliver the X-TRAS, without recourse to or warranty by the Trustee
or any Certificateholder, to any Person.  In any such case, the Trustee shall
sell, assign, contract to sell or otherwise dispose of and deliver the X-TRAS
at public or private sale, at any location at the option of the Trustee, all
upon such terms and conditions as it may reasonably deem advisable and at such
prices as it may reasonably deem advisable, for cash. If the Trustee so decides
or is required to sell or otherwise dispose of the X-TRAS pursuant to this
Section, the Trustee shall take such of the actions described above as it may
reasonably deem most effectual to complete the sale or other disposition of the
X-TRAS, so as to provide for the payment in full of all amounts due on the
Certificates.  The Trustee shall give notice to the Company promptly after any
such sale.  Notwithstanding the foregoing, any action taken by the Trustee
under this Section shall not, in the reasonable judgment of the Trustee, be
adverse to the best interests of the Certificateholders.
   43

                                     37

         Section 6.02.  Incidents of Sale of the X-TRAS.  Upon any sale of the
X-TRAS made either under the power of sale given under this Trust Agreement or
otherwise for the enforcement of this Trust Agreement, the following shall be
applicable:

         (1) Certificateholders and Trustee May Purchase the X-TRAS.  Any
    Certificateholder, the Trustee in its individual or any other capacity or
    any other Person may bid for and purchase the X-TRAS, and upon compliance
    with the terms of sale, may hold, retain, possess and dispose of the
    X-TRAS in their or its or his own absolute right without further
    accountability.
    
         (2) Receipt of Trustee Shall Discharge Purchaser.  The receipt of
    the Trustee or of the officer making such sale shall be a sufficient
    discharge to any purchaser for his purchase money, and, after paying such
    purchase money and receiving such receipt, such purchaser or his personal
    representative or assigns shall not be obliged to see to the application
    of such purchase money, or be in any way answerable for any loss,
    misapplication or non-application thereof.
    
   
         (3) Application of Moneys Received upon Sale.  Any moneys collected
    by the Trustee upon any sale made either under the power of sale given by
    this Agreement or otherwise for the enforcement of this Agreement, shall
    be applied as provided in Section 4.02.  If in connection with any Event
    of Default as to which moneys are collected by the Trustee the amounts
    collected are less than the amounts due in respect of (i) the principal
    of and interest on the X-TRAS and (ii) the ISDA Amount, if any, the
    amounts received by the Trustee will be distributed on a pro rata basis
    to the Certificateholders, on the one hand, and the Extension Option
    Buyer, on the others; provided that no such distribution shall affect the
    rights of the Trustee to demand and receive payment in full of all
    amounts due from the Company.
    
    
         Section 6.03.  Judicial Proceedings Instituted by Trustee.  (a) 
Trustee May Bring Suit.  If there shall be a failure to make payment of the
principal of, premium, if any, or interest on any X-TRAS, then the Trustee, as
holder of such X-TRAS, to the extent permitted by and in accordance with the
terms of the Indenture, shall be entitled and empowered to institute any suits,
actions or proceedings at law, in equity or otherwise, for the collection of
the sums so due and unpaid on such X-TRAS and may prosecute any such claim or
proceeding to judgment or final decree with respect to the whole amount of any
such sums so due and unpaid.

         (b) Trustee May File Proofs of Claim; Appointment of Trustee as
Attorney-in-Fact in Judicial Proceedings.  The Trustee in the name of the Trust
or as attorney-in-fact for the Certificateholders, or in any one or more of
such capacities (irrespective of whether distributions on the Certificates
shall then be due and payable, or the payment of the principal on the X-TRAS
shall then be due and payable, as therein expressed 
   44

                                      38

or by declaration or otherwise and irrespective of whether the Trustee shall
have made any demand to the Indenture Trustee for the payment of overdue
principal, premium (if any) or interest on the X-TRAS), shall be entitled and
empowered to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trust and of the
Certificateholders allowed in any receivership, insolvency, bankruptcy,
liquidation, readjustment, reorganization or any other judicial proceedings
relative to the Company, its creditors or property.  Any receiver, assignee,
trustee, liquidator, sequestrator (or similar official) in any such judicial
proceeding is hereby authorized by each Certificateholder to make payments in
respect of such claim to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Certificateholders, to
pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel. 
Nothing contained in this Agreement shall be deemed to give to the Trustee any
right to accept or consent to any plan of reorganization or otherwise by action
of any character in any such proceeding to waive or change in any way any right
of any Certificateholder.
        
         Section 6.04.  Control by Certificateholders.  Subject to Section 6.03
and the Indenture, the Certificateholders holding Certificates evidencing
Fractional Undivided Interests aggregating not less than a majority in interest
in the Assigned Trust Property shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
with respect to the Trust or pursuant to the terms of the Indenture, or
exercising any trust or power conferred on the Trustee under this Agreement or
the Indenture, including any right of the Trustee as holder of the X-TRAS,
provided that

   
         (1) such Direction shall not be in conflict with any rule of law or
    with this Agreement and would not involve the Trustee in personal
    liability or expense,
    
    
         (2) the Trustee shall not determine that the action so directed
    would be unjustly prejudicial to the Certificateholders not taking part
    in such Direction, and
    
         (3) the Trustee may take any other action deemed proper by the
    Trustee which is not inconsistent with such Direction.

         Section 6.05.  Waiver of Past Defaults.  Subject to the Indenture, the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Assigned
Trust Property (i) may on behalf of all of the Certificateholders waive any
past Event of Default hereunder and its consequences or (ii) may direct the
Trustee to instruct the Indenture Trustee to waive any past Indenture Default
under the Indenture and its consequences and thereby annul any Direction given
by such Certificateholders or the Trustee to the Indenture Trustee with respect
thereto, except a default:
   45

                                     39

         (1) in the deposit of any Scheduled Payment or Special Payment under
    Section 4.01 or in the distribution of any payment under Section 4.02 on
    the Certificates, or
    
         (2) in the payment of the principal of (premium, if any) or interest

         (3) in respect of a covenant or provision hereof which under Article
    X cannot be modified or amended without the consent of each
    Certificateholder holding an Outstanding Certificate affected thereby or
    the Extension Option Buyer.
    
         Upon any such waiver, such default shall cease to exist with respect to
the Certificates and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose and any direction given by the Trustee on
behalf of the Certificateholders to the Indenture Trustee shall be annulled
with respect thereto; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.  Upon
any such waiver, the Trustee shall vote the X-TRAS issued under the relevant
Indenture to waive the corresponding Indenture Default.

   
         Section 6.06.  Right of Certificateholders to Receive Payments Not to
Be Impaired.  Anything in this Agreement to the contrary notwithstanding,
including, without limitation, Section 6.07 hereof, but subject to the
Indenture, the right of any Certificateholder to receive distributions of
payments required pursuant to Section 4.02 hereof on the Certificates when due,
or to institute suit for the enforcement of any such payment on or after the
applicable Regular Distribution Date or Special Distribution Date, shall not be
impaired or affected without the consent of such Certificateholder.
    

         Section 6.07.  Certificateholders May Not Bring Suit Except Under
Certain Conditions.  A Certificateholder shall not have the right to institute
any suit, action or proceeding at law or in equity or otherwise with respect to
this Agreement, for the appointment of a receiver or for the enforcement of any
other remedy under this Agreement, unless:

         (1) such Certificateholder previously shall have given written
    notice to the Trustee of a continuing Event of Default;
    
         (2) Certificateholders holding Certificates evidencing Fractional
    Undivided Interests aggregating not less than 25% of the Assigned Trust
    Property shall have requested the Trustee in writing to institute such
    action, suit or proceeding and shall have offered to the Trustee
    indemnity as provided in Section 7.03(e);
   46

                                     40
    
         (3) the Trustee shall have refused or neglected to institute such an
    action, suit or proceeding for 60 days after receipt of such notice,
    request and offer of indemnity; and
    
   
         (4) no direction inconsistent with such written request shall have
    been given to the Trustee during such 60-day period by Certificateholders
    holding Certificates evidencing Fractional Undivided Interests
    aggregating not less than a majority in interest in the Assigned Trust
    Property.
    
    
         It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatsoever hereunder or
under the Certificates to (i) surrender, impair, waive, affect, disturb or
prejudice any property in the Assigned Trust Property or the lien of any
Indenture on any property subject thereto, or the rights of the
Certificateholders or the holders of the X-TRAS, (ii) obtain or seek to obtain
priority over or preference with respect to any other such Certificateholder or
(iii) enforce any right under this Agreement, except in the manner herein
provided and for the equal, ratable and common benefit of all the
Certificateholders subject to the provisions of this Agreement.

         Section 6.08.  Remedies Cumulative.  Every remedy given hereunder to
the Trustee or to any of the Certificateholders shall not be exclusive of any
other remedy or remedies, and every such remedy shall be cumulative and in
addition to every other remedy given hereunder or now or hereafter given by
statute, law, equity or otherwise.

   
                                 ARTICLE VII
    

                                 THE TRUSTEE

         Section 7.01.  Certain Duties and Responsibilities.  (a)  Except during
the continuance of an Event of Default, the Trustee undertakes to perform such
duties as are specifically set forth in this Agreement, and no implied
covenants or obligations shall be read into this Agreement against the Trustee.

         (b) In case an Event of Default has occurred and is continuing, the 
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, 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 its
own affairs.

         (c) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that
   47

                                     41

   
         (1) this Subsection shall not be construed to limit the effect of
    subsection (a) of this Section; and
    
    
         (2) the Trustee shall not be liable for any error of judgment made
    in good faith by a Responsible Officer of the Trustee, unless it shall be
    proved that the Trustee was negligent in ascertaining the pertinent
    facts.
    
         (d) Whether or not herein expressly so provided, every provision of
this Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

         Section 7.02.  Notice of Defaults.  As promptly as practicable after,
and in any event within 90 days after, the occurrence of any default (as such
term is defined below) hereunder, the Trustee shall transmit by mail to the
Company, the Indenture Trustee and the Certificateholders in accordance with
Section 313(c) of the Trust Indenture Act, notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default on the payment of the
principal, premium, if any, or interest on any X-TRAS, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interests of the Certificateholders.  For the purpose of this
Section, the term "default" means any event that is, or after notice or lapse
of time or both would become, an Event of Default.

   
         Section 7.03.  Certain Rights of Trustee.  Subject to the provisions of
Section 315 of the Trust Indenture Act:
    

   
         (a) the Trustee may rely and shall be protected in acting or
    refraining from acting in reliance upon any resolution, certificate,
    statement, instrument, opinion, report, notice, request, direction,
    consent, order, bond, debenture or other paper or document believed by it
    to be genuine and to have been signed or presented by the proper party or
    parties;
    
    
         (b) any request or direction of the Company mentioned herein shall
    be sufficiently evidenced by a written description of the subject matter
    thereof accompanied by an Officer's Certificate and an Opinion of Counsel
    as provided in Section 1.02 of this Agreement;
    
         (c) whenever in the administration of this Agreement the Trustee
    shall deem it desirable that a matter be proved or established prior to
    taking, suffering or omitting any action hereunder, the Trustee (unless
    other evidence be herein 
   48

                                     42

    specifically prescribed) may, in the absence of bad faith on its part, rely
    upon an Officer's Certificate of the Company or the Indenture Trustee;
        
         (d) the Trustee may consult with counsel and the advice of such
    counsel or any Opinion of Counsel shall be full and complete
    authorization and protection in respect of any action taken, suffered or
    omitted by it hereunder in good faith and in reliance thereon;
    
         (e) the Trustee shall be under no obligation to exercise any of the
    rights or powers vested in it by this Agreement at the Direction of any
    of the Certificateholders pursuant to this Agreement, unless such

    or indemnity against the cost, expenses and liabilities which might be
    incurred by it in compliance with such Direction;
    
         (f) the Trustee shall not be bound to make any investigation into
    the facts or matters stated in any resolution, certificate, statement,
    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture or other paper or document;
    
         (g) the Trustee may execute any of the trusts or powers under this
    Agreement or perform any duties under this Agreement either directly or
    by or through agents or attorneys, and the Trustee shall not be
    responsible for any misconduct or negligence on the part of any agent or
    attorney appointed with due care by it under this Agreement;
        
   
         (h) 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 Certificateholders holding Certificates evidencing
    Fractional Undivided Interests aggregating not less than a majority in
    interest in the Assigned Trust Property 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 Agreement; and
    
    
         (i) the Trustee shall not be required to expend or risk its own
    funds in the performance of any of its duties under this Agreement, 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 is not reasonably assured to it.
    
         Section 7.04.  Not Responsible for Recitals or Issuance of
Certificates. The recitals contained herein and in the Certificates, except the
certificates of authentication, shall not be taken as the statements of the
Trustee, and the Trustee assumes no responsibility for their correctness. 
Subject to Section 7.15, the Trustee makes no representations as to the
   49

                                     43

   
validity or sufficiency of this Agreement, any X-TRAS or the Certificates,
except that the Trustee hereby represents and warrants that this Agreement has
been [and the Registration Rights Agreement] and each Certificate will be,
executed, authenticated and delivered by one of its officers who is duly
authorized to execute, authenticate and deliver such document on its behalf.
    

         Section 7.05.  May Hold Certificates.  The Trustee, any Paying Agent,
Registrar or any of their Affiliates or any other agent in their respective
individual or any other capacity may become the owner or pledgee of
Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture
Act, if applicable, may otherwise deal with the Company or the Indenture
Trustee with the same rights it would have if it were not Trustee, Paying
Agent, Registrar or such other agent.

         Section 7.06.  Money Held in Trust.  Money held by the Trustee or the
Paying Agent in trust hereunder need not be segregated from other funds except
to the extent required herein or by law and neither the Trustee nor the Paying
Agent shall have any liability for interest upon any such moneys except as
provided for herein.

         Section 7.07.  Compensation and Reimbursement.  The Company agrees:

         (a) to pay, or cause to be paid, to the Trustee from time to time
    reasonable compensation for all services rendered by it hereunder as the
    Company and the Trustee shall agree in writing (which compensation shall
    not be limited by any provision of law in regard to the compensation of a
    trustee of an express trust); and
    
   
         (b) except as otherwise expressly provided herein, to reimburse, or
    cause to be reimbursed, the Trustee upon its request for all reasonable
    out-of-pocket expenses, disbursements and advances incurred or made by
    the Trustee in accordance with any provision of this Agreement (including
    the reasonable compensation and the expenses and disbursements of its
    agents and counsel), except any such expense, disbursement or advance as
    may be attributable to its negligence, willful misconduct or bad faith or
    as may be incurred due to the Trustee's breach of its representations and
    warranties set forth in Section 7.15; and
    
    
         (c) to the fullest extent permitted by law, to indemnify the Trustee
    or any predecessor Trustee for, and to hold the Trustee harmless against,
    any loss, damage, claim, liability, penalty or reasonable expenses
    incurred without negligence, bad faith or willful misconduct on its part,
    arising out of or in connection with the acceptance or administration of
    this Agreement, the Certificates, the ISDA Master Agreement or the
    Purchase Agreement, including the reasonable costs and expenses
    (including reasonable counsel fees and expenses) of defending itself
    against any claim or liability in connection with the exercise or
    performance of any of its powers or duties 
   50

                                     44

    hereunder, except any such cost or expense as may be attributable to the
    Trustee's negligence, bad faith or willful misconduct.
        
         The Trustee shall be entitled to reimbursement from the Company for any
tax incurred without negligence, bad faith or willful misconduct, on its part,
arising out of or in connection with the acceptance or administration of such
Trust (other than any tax attributable to the Trustee's compensation for
serving as such), including any reasonable costs and expenses incurred in
contesting the imposition of any such tax.

         Section 7.08.  Corporate Trustee Required; Eligibility.  There shall 
at all times be a Trustee hereunder which shall be eligible to act as a trustee
under Section 310(a) of the Trust Indenture Act and shall have a combined
capital and surplus of at least $75,000,000 (or a combined capital and surplus
in excess of $5,000,000 and the obligations of which, whether now in existence
or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000).  If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of
conditions so published.
        
         In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee, the
Trustee shall resign immediately as Trustee in the manner and with the effect
specified in Section 7.09.

   
         Section 7.09.  Resignation and Removal; Appointment of Successor.  (a) 
No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 7.10.
    

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

         (c) The Trustee may be removed at any time by Direction of the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Assigned
Trust Property delivered to the Trustee,  the Company and the Indenture
Trustee.
   51

                                     45

         (d) If at any time:

         (1) the Trustee shall fail to comply with Section 310 of the Trust
    Indenture Act, if applicable, after written request therefor by the
    Company or by any Certificateholder who has been a bona fide
    Certificateholder for at least six months; or
    
         (2) the Trustee shall cease to be eligible under Section 7.08 and
    shall fail to resign after written request therefor by the Company or by
    any such Certificateholder; 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 case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

   
         (e) If a Responsible Officer of the Trustee shall obtain actual
knowledge of an Avoidable Tax which has been or is likely to be asserted, the
Trustee shall promptly notify the Company and shall, within 30 days of such
notification, resign hereunder unless within such 30-day period the Trustee
shall have received notice that the Company has agreed to pay such tax.  The
Company shall promptly appoint a successor Trustee in a jurisdiction where
there are no Avoidable Taxes.
    

         (f) If the Trustee shall resign, be removed or become incapable of
acting or if a vacancy shall occur in the office of the Trustee for any cause,
the Company shall promptly appoint a successor Trustee.  If, within one year
after such resignation, removal or incapability, or other occurrence of such
vacancy, a successor Trustee shall be appointed by Direction of the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Assigned
Trust Property  delivered to the Company, the Indenture Trustee and the
retiring Trustee, and the Company approves such appointment, which approval
shall not be unreasonably withheld, then the successor Trustee so appointed
shall, forthwith upon its acceptance of such appointment, become the successor
Trustee and supersede the successor Trustee appointed as provided above.  If no
successor Trustee shall have been so appointed as provided above and accepted
appointment in the manner hereinafter provided, any Certificateholder who has
been a bona fide Certificateholder for at least six months may, on behalf of
himself and all others 
   52

                                     46

similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee.
        
         (g) The successor Trustee shall give notice of the resignation and
removal of the Trustee and appointment of the successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Certificateholders as their names and addresses appear in the Register.  Each
notice shall include the name of such successor Trustee and the address of its
Corporate Trust Office.

         Section 7.10.  Acceptance of Appointment by Successor.  Every successor
Trustee appointed hereunder shall execute and deliver to the Company, the
Authorized Agents and the Indenture Trustee and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring Trustee shall execute and
deliver an instrument transferring to such successor Trustee all such rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all Assigned Trust Property held by such
retiring Trustee hereunder, subject nevertheless to its lien, if any, provided
for in Section 7.07.  Upon request of any such successor Trustee, the Company,
the retiring Trustee and such successor Trustee shall execute and deliver any
and all instruments containing such provisions as shall be necessary or
desirable to transfer and confirm to, and for more fully and certainly vesting
in, such successor Trustee all such rights, powers and trusts.

   
         No institution shall accept its appointment as a Trustee hereunder
unless at the time of such acceptance such institution shall be qualified and
eligible under this Article VII.
    

         Section 7.11.  Merger, Conversion, Consolidation or Succession to
Business.  Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of 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 VII, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.  In case any Certificates shall have
been executed or authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such execution or authentication and deliver
the Certificates so executed or authenticated with the same effect as if such
successor Trustee had itself executed or authenticated such Certificates.
   53

                                     47

         Section 7.12.  Maintenance of Agencies.  (a)  There shall at all times
be maintained an office or agency in the location set forth in Section 12.03
where Certificates may be presented or surrendered for registration of transfer
or for exchange, and for payment thereof and where notices and demands to or
upon the Trustee in respect of such certificates or this Agreement may be
served; provided, however, that, if it shall be necessary that the Trustee
maintain an office or agency in another location (e.g., the Certificates shall
be represented by definitive Certificates and shall be listed on a national
securities exchange), the Trustee will make all reasonable efforts to establish
such an office or agency.  Written notice of the location of each such other
office or agency and of any change of location thereof shall be given by the
Trustee to the Company, the Indenture Trustee (at its address as may be
notified to the Trustee) and the Certificateholders.  In the event that no such
office or agency shall be maintained or no such notice of location or of change
of location shall be given, presentations and demands may be made and notices
may be served at the Corporate Trust Office of the Trustee.

   
         (b) There shall at all times be a Registrar and a Paying Agent
hereunder with respect to the Certificates.  Each such Authorized Agent shall
be a bank or trust company, shall be a corporation organized and doing business
under the laws of the United States or any state, with a combined capital and
surplus of at least $75,000,000, or, if the Trustee shall be acting as the
Registrar or Paying Agent hereunder, a corporation having a combined capital
and surplus in excess of $5,000,000, the obligations of which are guaranteed by
a corporation organized and doing business under the laws of the United States
or any state, with a combined capital and surplus of at least $75,000,000, and
shall be authorized under such laws to exercise corporate trust powers, subject
to supervision by federal or state authorities.  The Trustee shall initially be
the Paying Agent and, as provided in Section 3.04, Registrar hereunder with
respect to the Certificates.  Each Registrar shall furnish to the Trustee, at
stated intervals of not more than six months, and at such other times as the
Trustee may request in writing, a copy of the Register maintained by such
Registrar.
    

         (c) Any corporation into which any Authorized Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authorized Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authorized Agent, shall be the successor of such Authorized Agent
hereunder, if such successor corporation is otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

         (d) Any Authorized Agent may at any time resign by giving written
notice of resignation to the Trustee, the Company and the Indenture Trustee. 
The Company may, and at the request of the Trustee shall, at any time terminate
the agency of any Authorized Agent by giving written notice of termination to
such Authorized Agent and to the Trustee.  
   54

                                     48

Upon the resignation or termination of an Authorized Agent or in case at any
time any such Authorized Agent shall cease to be eligible under this Section
(when, in either case, no other Authorized Agent performing the functions of
such Authorized Agent shall have been appointed), the Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section.  The Company shall give written notice of
any such appointment made by it to the Trustee and the Indenture Trustee; and
in each case the Trustee shall mail notice of such appointment to all
Certificateholders as their names and addresses appear on the Register.
        
         (e) The Company agrees to pay, or cause to be paid, from time to time
to each Authorized Agent reasonable compensation for its services and to
reimburse it for its reasonable expenses.

         Section 7.13.  Money for Certificate Payments to Be Held in Trust.  All
moneys deposited with any Paying Agent for the purpose of any payment on
Certificates shall be deposited and held in trust for the benefit of the
Certificateholders entitled to such payment, subject to the provisions of this
Section.  Moneys so deposited and held in trust shall constitute a separate
trust fund for the benefit of the Certificateholders with respect to which such
money was deposited.

   
         The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by 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.
    

         Section 7.14.  [Intentionally Omitted].
        
         Section 7.15.  Representations and Warranties of Trustee.  The Trustee
hereby represents and warrants that:

         (a) the Trustee is a Delaware banking corporation organized and
    validly existing in good standing under the laws of the State of
    Delaware;
    
         (b) the Trustee has full power, authority and legal right to
    execute, deliver, and perform this Agreement and has taken all necessary
    action to authorize the execution, delivery, and performance by it of
    this Agreement;
   55

                                     49

         (c) the execution, delivery and performance by the Trustee of this
    Agreement (i) will not violate any provision of United States federal law
    or the law of the state of the United States where it is located
    governing the banking and trust powers of the Trustee or any order, writ,
    judgment, or decree of any court, arbitrator or governmental authority
    applicable to the Trustee or any of its assets, (ii) will not violate any
    provision of the articles of association or by-laws of the Trustee, or
    (iii) will not violate any provision of, or constitute, with or without
    notice or lapse of time, a default under, or result in the creation or
    imposition of any lien on any properties included in the Assigned Trust
    Property pursuant to the provisions of any mortgage, indenture, contract,
    agreement or other undertaking to which it is a party, which violation,
    default or lien could reasonably be expected to have an adverse effect on
    the Trustee's performance or ability to perform its duties hereunder or
    thereunder or on the transactions contemplated herein or therein;
        
         (d) the execution and delivery by the Trustee of this Agreement will
    not require the authorization, consent, or approval of, the giving of
    notice to, the filing or registration with, or the taking of any other
    action in respect of, any governmental authority or agency of the United
    States or the state of the United States where it is located regulating
    the banking and corporate trust activities of the Trustee; and
    
         (e) this Agreement has been duly executed and delivered by the
    Trustee and, assuming due execution and delivery thereof by the other
    parties thereto, constitutes the legal, valid, and binding agreement of
    the Trustee, enforceable against it in accordance with its terms,
    provided that enforceability may be limited by (i) applicable bankruptcy,
    insolvency, reorganization, moratorium, fraudulent conveyance or similar
    laws affecting the rights of creditors generally and (ii) general
    principles of equity.
    
   
        Section 7.16.  Withholding Taxes; Information Reporting.  The Trust and
the Trustee shall exclude and withhold from each distribution of principal,
premium, if any, and interest and other amounts due under this Agreement or
under the Certificates any and all withholding taxes applicable thereto as
required by law.  The Trust shall request, and the Certificateholders shall
provide to the Trust, such forms or certificates as are necessary to establish
an exemption from withholding with respect to each Certificateholder, and any
representations and forms that shall be reasonably required by the Trust to
assist it in determining the extent of, and in fulfilling, its withholding
obligations.  The Trustee shall file required forms with applicable
jurisdictions and, unless an exemption from withholding is properly established
by a Certificateholder, shall remit amounts withheld with respect to the
Certificateholder to the applicable jurisdictions.  To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Certificateholder, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to the Certificateholder.  In the event of any claimed over-
    

   56

                                     50

withholding, Certificateholders shall be limited to an action against the
applicable jurisdiction.  If the amount required to be withheld was not
withheld from actual distributions made, the Trust may reduce subsequent
distributions by the amount of such withholding.
        

                                ARTICLE VIII

                           SUPPLEMENTAL AGREEMENTS

         Section 9.01.  Supplemental Agreements Without Consent of
Certificateholders.  Without the consent of the Certificateholders, the Company
may (but will not be required to), and the Trust (subject to Section 9.03)
shall, at any time and from time to time, enter into one or more agreements
supplemental hereto or, if applicable, to the ISDA Master Agreement in form
satisfactory to the Trustee, for any of the following purposes:

         (1) to evidence the succession of another corporation to the Company
    and the assumption by any such successor of the covenants of the Company
    herein contained; or
   58

                                     52

   
         (2) to add to the covenants, restrictions or obligations of the
    Company or Trustee; or
    
    
         (3) to add to or supplement any security for the benefit of any
    Certificateholders; or
    
         (4) to cure any ambiguity or correct or supplement any provision
    which may be defective or inconsistent with any other provision in the
    Agreement, Indenture or the ISDA Master Agreement or to make such other
    provisions as the Company deems necessary or desirable with respect to
    matters or questions arising under the Agreement, provided that no such
    action materially adversely affects the interests of any
    Certificateholders; or
    
         (5) to modify, eliminate or add to the provisions of this Agreement
    to such extent as shall be necessary to continue the qualification of
    this Agreement (including any supplemental agreement) under the Trust
    Indenture Act or under any similar federal statute hereafter enacted, and
    to add to this Agreement such other provisions as may be expressly
    permitted by the Trust Indenture Act, excluding, however, the provisions
    referred to in Section 316(a)(2) of the Trust Indenture Act as in effect
    at the date as of which this instrument was executed or any corresponding
    provision in any similar federal statute hereafter enacted; or
    
         (6) to evidence and provide for the acceptance of appointment under
    this Agreement by the Trustee of a successor Trustee and to add to or
    change any of the provisions of this Agreement as shall be necessary to
    provide for or facilitate the administration of the Trust, pursuant to the

         (7) to provide the information required under Section 7.12 and
    Section 12.03 as to the Trustee; or
    
    
         (8) to modify or amend any provision of the Agreement that relates
    to the ISDA Master Agreement or the Remarketing Procedure so long as such
    modification or amendment does not have a material adverse effect on the
    Certificateholders; or
    
         (9) to comply with the requirements of the Code;
    
provided further that no such amendment referred to in the foregoing clauses
(1) through (9)  which has a material adverse effect on the Extension Option
Buyer may be entered into without the consent of the Extension Option Buyer,
and no such amendment, as evidenced by an Opinion of Counsel, shall alter the
status of the Trust as a grantor trust under the Code or result in an actual or
constructive sale or exchange of any Certificate for tax purposes.

                                     53

         Section 9.02.  Supplemental Agreements with Consent of
Certificateholders. With the consent of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the Assigned Trust Property, by Direction of
said Certificateholders delivered to the Company and the Trustee, the Company
may, and the Trustee (subject to Section 9.03) shall, enter into an agreement
or agreements for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying
in any manner the rights and obligations of such Certificateholders under this
Agreement, provided, however, that no such agreement which has a material
adverse effect on the Extension Option Buyer may be entered into without the
consent of the Extension Option Buyer; provided further that no such agreement
shall, without the consent of the Certificateholder of each Outstanding
Certificate affected thereby, be entered into which:

         (1) alters in any manner the amount or timing of any receipt by the
    Trustee of payments on the X-TRAS held in the Trust or distributions that
    are required to be made herein on any Certificate, or changes any date of
    payment on any Certificate, or changes the place of payment where, or the
    coin or currency in which, any Certificate is payable, or impairs the
    right to institute suit for the enforcement of any such payment or
    distribution on or after the Regular Distribution Date or Special
    Distribution Date applicable thereto; or
    
         (2) permits the disposition of any X-TRAS included in the Assigned
    Trust Property except as permitted by this Agreement, or otherwise
    deprives such Certificateholder of the benefit of the ownership of the
    X-TRAS in the Trust; or
    
   
         (3) reduces the percentage of the aggregate Fractional Undivided
    Interests of the Assigned Trust Property which is required for any such
    supplemental agreement which adversely affects in any material respect
    the interests of the Certificateholders, or reduces such percentage
    required for any waiver of compliance with certain provisions of this
    Agreement or certain defaults hereunder and their consequences provided
    for in this Agreement; or
    
    
         (4) modifies any of the provisions of this Section 9.02 or Section
    6.05, except to increase any such percentage or to provide that certain
    other provisions of this Agreement cannot be modified or waived without
    the consent of the Certificateholder of each Certificate affected
    thereby; or
    
         (5) results in the exchange or substitution of any Certificates
    pursuant to a plan for the refunding or refinancing of such Certificates;
   60

                                      54

unless such vote or consent would not, based on the Opinion of Counsel, alter
the status of the Trust as a grantor trust under the Code or result in an
actual or constructive sale or exchange of any X-TRAS for tax purposes.

         It shall not be necessary for any Direction of Certificateholders under
this Section to approve the particular form of any proposed supplemental
agreement, but it shall be sufficient if such Direction shall approve the
substance thereof.

         Section 9.03.  Documents Affecting Immunity or Indemnity.  If in the
opinion of the Trustee any document required to be executed by it pursuant to
the terms of Section 9.01 or 9.02 affects any interest, right, duty, immunity
or indemnity in favor of the Trustee under this Agreement, the Trustee may in
its discretion decline to execute such document.

         Section 9.04.  Execution of Supplemental Agreements.  In executing, or
accepting the additional trusts created by, any agreement permitted by this
Article or the modifications thereby of the trusts created by this Agreement,
the Trustee shall be entitled to receive, and shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such
supplemental agreement is authorized or permitted by this Agreement.

         Section 9.05.  Effect of Supplemental Agreements.  Upon the execution
of any agreement supplemental to this Agreement under this Article, this
Agreement shall be modified in accordance therewith, and such supplemental
agreement shall form a part of this Agreement for all purposes; and every
Holder of a Certificate theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

         Section 9.06.  Conformity with Trust Indenture Act.  Every supplemental
agreement executed pursuant to this Article shall conform to the requirements
of the Trust Indenture Act as then in effect.

   
         Section 9.07.  Reference in Certificates to Supplemental Agreements.
Certificates authenticated and delivered after the execution of any
supplemental agreement pursuant to this Article may bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
agreement; and, in such case, suitable notation may be made upon Outstanding
Certificates after proper presentation and demand.

                                     55

                                  ARTICLE X

                           AMENDMENTS TO INDENTURE

   
        Section 10.01.  Amendments and Supplements to Indentures.  The Trustee,
as holder of the X-TRAS, has the right to vote and give consents and waivers in
respect of the X-TRAS and enforce such other rights of a holder of the X-TRAS
except as otherwise limited by this Agreement or the Indenture.  Each
Certificateholder shall be entitled to direct the Trustee to vote a principal
amount of the X-TRAS corresponding to the principal amount of the Certificates
held by such Certificateholder in the manner directed by the Certificateholder.
In the event that the Trust, as holder of any X-TRAS, receives from the Company
or, if applicable, any depositary with respect to the X-TRAS, a request for the
Trustee's consent to any amendment, modification of the X-TRAS, or any document
thereunder, or relating thereto or waiver or receives any other solicitation
for any action with respect to the X-TRAS, the Trustee shall within five
Business Days mail a notice of such proposed amendment, modification, waiver or
solicitation to each Certificateholder registered on the Register as of the
date of such request.  The Trustee shall request from the Certificateholders a
Direction as to (a) whether or not to take or refrain from taking any action
which a holder of such X-TRAS has the option to direct, (b) whether or not to
give or execute any waivers, consents, amendments, modifications or supplements
as a holder of such X-TRAS and (c) how to vote any X-TRAS if a vote has been
called for with respect thereto.  Provided such a request for Certificateholder
Direction shall have been made, in directing any action or casting any vote or
giving any consent as the holder of any X-TRAS, the Trust shall consent or
vote, or refrain from consenting or voting, in the same proportion as that of
(i) the aggregate face amounts of all Certificates actually voted or not voted
in favor of or for giving consent to such action by such Direction of
Certificateholders to (ii) the aggregate face amount of all Outstanding
Certificates, as of the date determined by the Trustee prior to the date such
vote or consent as a holder of X-TRAS is required; provided, however, that, the
Trustee shall at no time, without the consent of each Certificateholder, vote
in favor or consent to any matter (i) unless such vote or consent would not,
based on an Opinion of Counsel, alter the status of the Trust as a grantor
trust under the Code or result in an actual or constructive sale or exchange of
any X-TRAS for tax purposes, (ii) which would alter the timing or amount of any
payment on the X-TRAS, or (iii) which would result in the exchange or
substitution of any X-TRAS pursuant to a plan for the refunding or refinancing
of such X-TRAS, and without the written consent of the Company. The Trustee
shall have no liability for any failure to act resulting from the
Certificateholders' late return of, or failure to return, directions requested
by the Trustee from the Certificateholders.  For purposes of the second
immediately preceding sentence, a Certificate shall have been "actually voted"
if the Holder of such Certificate has delivered to the Trustee an instrument
evidencing such Holder's consent to such Direction prior to two Business Days
before the Trustee directs such action or casts such vote or gives such
consent.  Notwithstanding the foregoing, but subject to Section 6.04 and the
Indenture, (i) the Trustee may, in its own 
    

   62

                                     56

   
discretion and at its own direction, consent and notify the Indenture Trustee
of such consent to any amendment, modification, waiver or supplement under the
Indenture (including, without limitation, in respect of the obligations
relating to payment of the ISDA Amount and the provisions of Article X), if an
Event of Default hereunder shall have occurred and be continuing, or if such
amendment, modification or waiver will not adversely affect the interests of
the Certificateholders and (ii) no such amendment, modification or waiver shall
be made that adversely affects in any material respect the interests of the
Extension Option Buyer without its consent.
    
        

                                 ARTICLE XI

             PAYMENT OF FINAL DISTRIBUTION; TERMINATION OF TRUST

   
         Section 11.01.  Payment of Final Distribution.  (a)  If the X-TRAS are
extended until the Extended Stated Maturity, then, unless the Company exercises
its option to redeem the X-TRAS under Section 7.01(c) of the Indenture (which
option the Company shall be entitled to exercise at any time subsequent to the
delivery of the Extension Notice and prior to the earlier of the pricing of the
remarketing and the Remarketing Deadline upon delivery of an irrevocable notice
of redemption), the interest rate borne by the X-TRAS will be reset on the
pricing of the remarketing effective on and as of the date of closing of the
remarketing in order that the X-TRAS may be remarketed so as to yield net
proceeds in cash at least equal to the sum of (i) 100% of the principal amount
of the X-TRAS plus (ii) the ISDA Amount as of the Exercise Date as calculated
by the Calculation Agent and notified to the Issuer, the Trustee and the
Indenture Trustee within five Business Days thereafter (collectively, the
"Required Remarketing Proceeds").   As more particularly set forth in the next
sentence, it is intended that the portions of the Required Remarketing Proceeds
representing the principal amount of the X-TRAS, together with the amount
payable by the Company pursuant to such sentence, will be sufficient to enable
the Trustee to make the Final Distribution on the Certificates.  Accordingly,
the Company shall be obligated to pay to the Trust, simultaneously with the
closing of the remarketing, an amount equal to the interest that would have
accrued on the X-TRAS had they been held by the Trust to the Final Distribution
Date.   Upon payment of the Final Distribution to Certificateholders and the
ISDA Amount to the Extension Option Buyer on the Final Distribution Date, the
Company shall be entitled to receive any amounts earned in respect of the
investment by the Trustee of the Required Remarketing Proceeds and the ISDA
Amount in Permitted Investments pursuant to clause (iv) below.  In the event
the X-TRAS are remarketed, the Company shall have no obligation to pay the
principal amount of the X-TRAS to the Trust on the Initial Stated Maturity. The
X-TRAS will be remarketed in accordance with the following procedure (the
"Remarketing Procedure"):
    

   63

                                     57

   
         (i)   On the Exercise Date and thereafter on the 75th, 60th, 45th,
    30th and 15th day prior to the Initial Stated Maturity, Morgan Stanley &
    Co. Incorporated (or, subsequent to the Exercise Date, such other
    investment banking institution as may be selected as the Remarketing Agent)
    will provide the Company with non-binding indications of the interest rate
    at which and proceeds for which it believes it could remarket the X-TRAS in
    order to yield the Required Remarketing Proceeds.
    
        
         (ii)  Morgan Stanley & Co. Incorporated shall act as the Remarketing
    Agent for the X-TRAS unless, no later than 60 days prior to the Final
    Distribution Date, the Company shall select another investment banking
    institution to remarket the X-TRAS.
    
         (iii) No later than 15 days prior to the Remarketing Deadline, the
    Remarketing Agent will commence marketing of the X-TRAS to investors.
    
   
         (iv)  Pricing and closing of the remarketed X-TRAS shall occur at any
    time within 10 days prior to the Remarketing Deadline, subject to then
    prevailing market conditions and settlement cycles.  The Trustee shall
    have no obligation to release the X-TRAS for delivery to the purchasers
    thereof pursuant to this Section 11.01(a) unless the proceeds from such
    purchase shall at least equal the Required Remarketing Proceeds.  Upon
    completion of the remarketing, the net proceeds thereof, together with
    the amount equal to the interest that would have accrued on the X-TRAS
    had they been held by the Trust to the Final Distribution Date payable by
    the Company pursuant to the first paragraph of this Section 11.01, will
    be deposited with the Trustee and invested by the Trustee in Permitted
    Investments pending their distribution on the Final Distribution Date.
    
    
   
         (v)   On the Final Distribution Date, the Trustee shall distribute (x)
    an amount equal to 100% of the aggregate principal amount of the X-TRAS
    plus accrued interest from the last Interest Payment Date (as defined in
    the Indenture) until the Final Distribution Date assuming the X-TRAS had
    been outstanding and held by the Trust until such date to the
    Certificateholders and (y) an amount equal to the ISDA Amount to the
    Extension Option Buyer in accordance with the ISDA Master Agreement.
    
    
         (vi)  The Remarketing Agent will be entitled to underwriter discounts
    and commissions, payable at settlement of the Remarketing Procedure,
    which will be determined at the time the Remarketing Procedure is
    commenced and shall be consistent with then prevailing market practices.
    In the event that Morgan Stanley & Co. Incorporated purchases the X-TRAS
    pursuant to clause (ix) below, it shall be entitled to underwriter
    discounts and commissions, payable at settlement of such purchase, which
    will be determined at the time it gives notice of its offer pursuant to
    clause (ix) below and shall be consistent with then prevailing market
    practices.
   64

                                     58

         (vii)  The Company will cooperate with and provide information
    reasonably requested by the Remarketing Agent and (in the event of an
    offer to purchase by Morgan Stanley & Co. Incorporated made pursuant to
    clause (ix) below) by Morgan Stanley & Co. Incorporated in connection with
    the remarketing or purchase of the X-TRAS, as applicable, including,
    without limitation, (A) promptly preparing an offering memorandum or
    prospectus containing such disclosures as may be required by applicable law
    and as may be required by the Remarketing Agent or Morgan Stanley & Co.
    Incorporated, as applicable, in its reasonable judgment, (B) executing and
    delivering or causing to be executed and delivered legal documentation
    (including a purchase agreement or underwriting agreement and registration
    rights agreement with customary indemnities, covenants, representations and
    warranties, comfort letters and legal opinions) in form and substance
    reasonably satisfactory to the Remarketing Agent or Morgan Stanley & Co.
    Incorporated, as applicable, (C) providing promptly upon request updated
    consolidated financial statements to the date of its latest report filed
    with the SEC and (D) to the extent the Company and the Remarketing Agent or
    Morgan Stanley & Co. Incorporated, as applicable, deem reasonably necessary
    for successful completion of the Remarketing Procedure or the purchase by
    Morgan Stanley & Co. Incorporated, as applicable, making available senior
    management of the Company for road show and one-on-one presentations.
        
         (viii) The Company may, in its sole discretion, elect to cause the
    X-TRAS to be remarketed by conducting an underwritten offering or private
    placement thereof on a firm-commitment basis.  In such event, the Company
    shall notify the Remarketing Agent of such request no later than 70 days
    prior to the Final Distribution Date.  The Company acknowledges that in
    no event shall the Remarketing Agent be deemed by this provision to have
    made a commitment to underwrite or place the X-TRAS.
    
   
         (ix)   Regardless of whether it has been selected to act as
    Remarketing Agent, Morgan Stanley & Co. Incorporated shall at all times
    be permitted to make an offer, on not less than [five] Business Days'
    notice, to purchase the X-TRAS on a date not later than the Remarketing
    Deadline and bearing a reset interest rate specified by Morgan Stanley &
    Co. Incorporated that would result in proceeds in cash equal to the
    Required Remarketing Proceeds, which offer the Company and the Trustee
    shall be required to accept, unless, on or prior to the date for such
    purchase specified in the notice provided by Morgan Stanley & Co.
    Incorporated, (A) the Company shall have delivered an irrevocable notice
    of redemption pursuant to Section 7.01(c) of the Indenture and Section
    11.01(b) of this Agreement or (B) any other party shall have remarketed
    the X-TRAS bearing a reset interest rate less than or equal to that
    specified by Morgan Stanley & Co. Incorporated for net proceeds in cash
    equal to the Required Remarketing Proceeds.
    

   65

                                     59

         (x)    The Trustee shall be entitled to an indemnity, in form and
    substance reasonably satisfactory to it, from the Company against any
    loss, liability, damage, claim or expense that it may incur in connection
    with the Remarketing Procedure, whether or not the X-TRAS are remarketed,
    including liabilities under the Securities Act, and to contribution from
    the Company in respect of any payments that the Trustee may be required to
    make in respect of any such loss, liability, damage, claim or expense. In
    addition, any definitive documentation executed and delivered in connection
    with any remarketing of the X-TRAS shall be in form and substance
    reasonably satisfactory to the Trustee and its legal counsel.
        
   
         (xi) The remarketed X-TRAS will bear interest at the reset interest
    rate commecing upon the date of closing of the remarketing.  For the
    avoidance of doubt, holders of the remarketed X-TRAS shall not be
    entitled to receive any interest thereon for any period prior to the date
    of closing of the remarketing.
    
    
         (b) If the X-TRAS are extended until the Extended Stated Maturity, the
Company may, in lieu of permitting the X-TRAS to be remarketed, exercise its
option under Section 7.01(c) of the Indenture to redeem the X-TRAS, in whole,
on the Final Distribution Date, by irrevocable notice given to the Indenture
Trustee, the Trustee, the Extension Option Buyer, Morgan Stanley & Co.
Incorporated and the Calculation Agent not later than the Remarketing Deadline,
at a redemption price equal to the sum of (i) 100% of the aggregate principal
amount thereof together with accrued interest, if any, thereon to the Final
Distribution Date plus (ii) the ISDA Amount as of the Exercise Date as
calculated by the Calculation Agent and notified to the Company, the Indenture
Trustee and the Trustee within five Business Days thereafter, in which case the
X-TRAS will not be remarketed.   Out of such amount, the Trustee will
distribute on the Final Distribution Date (x) an amount equal to 100% of the
aggregate principal amount of the X-TRAS plus accrued interest to the
Certificateholders and (y) an amount equal to the ISDA Amount to the Extension
Option Buyer in accordance with the ISDA Master Agreement.

   
         (c) If the X-TRAS are extended until the Extended Stated Maturity and
the Trustee does not receive on or prior to the Remarketing Deadline an amount
in cash equal to sum of (i) 100% of the aggregate principal amount of the
X-TRAS plus accrued interest to the Final Distribution Date plus (ii) the ISDA
Amount because the X-TRAS have not been successfully remarketed and the Company
has not exercised its option under Section 7.01(c) of the Indenture to redeem
the X-TRAS, the Trustee shall exercise its option to require the Company to
repurchase (the "Put Option"), on the Final Distribution Date, all of the
outstanding X-TRAS at a purchase price equal to 100% of the aggregate principal
amount of and accrued interest on the X-TRAS to the Final Distribution Date.
The Trustee will distribute such entire amount to the Certificateholders.

and responsibilities of the Company, the Trust and the Trustee (i) which are
for the benefit of the Certificateholders shall terminate upon the distribution
to all of the Certificateholders and the Trustee of all amounts required to be
distributed to them pursuant to this Agreement and the disposition of all
property held as part of the Assigned Trust Property and (ii) which are for the
benefit of the Extension Option Buyer shall terminate upon the payment to the
Extension Option Buyer of all amounts due to it under the ISDA Master
Agreement; provided, however, that in no event shall the Trust continue beyond
one hundred ten (110) years following the date of the earliest execution of
this Trust Agreement.
    
        
   
         Notice of any termination, specifying the Regular Distribution Date (or
Special Distribution Date, as the case may be) upon which the
Certificateholders may surrender their Certificates to the Trustee for payment
on the Final Distribution Date and cancellation, shall be mailed promptly by
the Trustee to Certificateholders not earlier than the 60th day and not later
than the 20th day next preceding such final Distribution Date specifying (A)
the Regular Distribution Date (or Special Distribution Date, as the case may
be) upon which the proposed final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office or agency of the
Trustee therein specified, (B) the amount of any such proposed final payment,
and (C) that the Record Date otherwise applicable to such Regular Distribution
Date (or Special Distribution Date, as the case may be) is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office or agency of the Trustee therein specified.  The Trustee shall give
such notice to the Registrar at the time such notice is given to
Certificateholders.  Upon presentation and surrender of the Certificates in
accordance with such notice, the Trustee shall cause to be distributed to
Certificateholders such final payments.
    

         In the event that all of the Certificateholders shall not surrender
their Certificates for cancellation within six months after the date specified
in the above-mentioned written notice, the Trustee shall give a second written
notice to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto.  No
additional interest shall accrue on the Certificates after the Regular
Distribution Date (or Special Distribution Date, as the case may be) specified
in the first written notice.  In the event that any money held by the Trustee
for the payment of distributions on the Certificates shall remain unclaimed for
two years (or such lesser time as the Trustee shall be satisfied, after sixty
days' notice from the Company, is one month prior to the escheat period
provided under applicable law) after the final distribution date with respect
thereto, the Trustee shall pay to each Indenture Trustee the appropriate amount
of money relating to such Indenture Trustee and shall give written notice
thereof to the Company.

                          [REVERSE OF CERTIFICATE]


         The Certificates do not represent a direct obligation of, or an
obligation guaranteed by, or an interest in, the Company or the Trustee or any
of their affiliates.  The Certificates are limited in right or payment, all as
more specifically set forth on the face hereof and in the Agreement.  All
payments or distributions made to Certificateholders under the Agreement shall
be made only from the Assigned Trust Property and only to the extent that the
Trust shall have sufficient income or proceeds from the Assigned Trust Property
to make such payments in accordance with the terms of the Agreement.  Each
Certificateholder of this Certificate, by its acceptance hereof, agrees that it
will look solely to the income and proceeds from the Assigned Trust Property to
the extent available for distribution to such Certificateholder as provided in
the Agreement.  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for information with respect to the
interests, rights, benefits, obligations, proceeds, and duties evidenced
hereby.  A copy of the Agreement may be examined during normal business hours
at the principal office of the Trustee, and at such other places, if any,
designated by the Trustee, by any Certificateholder upon request.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Certificateholders under the Agreement at any
time by the Company and the Trust with the consent of the Certificateholders
holding Certificates evidencing Fractional Undivided Interests aggregating not
less than a majority in interest in the Assigned Trust Property.  Any such
consent by the Certificateholder of this Certificate shall be conclusive and
binding on such Certificateholder and upon all future Certificateholders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate.  The Agreement also permits the amendment thereof,
in certain limited circumstances, without the consent of the Certificateholders
of any of the Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Register upon
surrender of this Certificate for registration of transfer at the offices or
agencies maintained by the Trustee in its capacity as Registrar, or by any
successor Registrar, in the Borough of Manhattan, the City of New York, duly
endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Trustee and the Registrar duly executed by the
Certificateholder hereof or such Certificateholder's attorney duly authorized
in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust will be issued to the designated transferee or transferees.

   
         The Certificates are issuable only as registered Certificates without
coupons in minimum denominations of $250,000 Fractional Undivided Interest and
integral multiples of $1,000 in excess thereof.  As provided in the Agreement
and subject to certain limitations therein set forth, the Certificates are
exchangeable for new Certificates of authorized

                                     A-7

   
denominations evidencing the same aggregate Fractional Undivided Interest in
the Assigned Trust Property, as requested by the Certificateholder surrendering
the same.
    
        
         No service charge will be made for any such registration of transfer or
exchange, but the Trustee shall require payment by the Holder of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

         The Trust, the Trustee, the Registrar and any agent of the Trust, the
Trustee or the Registrar may treat the person in whose name this Certificate is
registered as the owner hereof for all purposes, and the Trust, the Trustee,
the Registrar or any such agent shall not be affected by any notice to the
contrary.

         The obligations and responsibilities for the benefit of the
Certificateholders created by the Agreement and the Trust created thereby shall
terminate upon the distribution to Certificateholders of all amounts required
to be distributed to them pursuant to the Agreement and the disposition of all
property held as part of the Assigned Trust Property.
