proceeds thereof, together with amounts payable to it under a certain ISDA
Master Agreement (as defined), to purchase the Notes from the Company at the par
value thereof. The ability of the Pass-Through Trust to make distributions under
the Certificates will depend on whether the Company meets its obligations on the
Notes. Interest paid on the Notes will be passed through to the
Certificateholders on            and            of each year, commencing
           , 1998, at    % per annum and continuing until            , 2005, the
date on which the principal amount of the Notes will be distributed (the "Final
Distribution Date"). The Notes are redeemable at the option of the Company, in
whole or in part, at any time or from time to time, on not less than 30 days'
prior notice, at the redemption prices determined as described herein, together
with accrued interest to the date fixed for redemption. The Trustee will
distribute amounts received with respect to the Notes pursuant to any such
redemption to the Certificateholders on a Special Distribution Date (as
defined).

                                 Subsidiaries (as defined) to: incur or

INDENTURE TRUSTEE.............   NBD Bank will act as Indenture Trustee.
 
CERTAIN FEDERAL INCOME TAX
   CONSIDERATIONS.............   The Pass-Through Trust will be classified as a
                                 grantor trust and not as an association (or
                                 publicly traded partnership) taxable as a
                                 corporation for U.S. federal income tax
                                 purposes. For U.S. federal income tax purposes,
                                 while the characterization of the transaction
                                 is not without doubt, Federal Tax Counsel (as
                                 defined) believes that the Certificates
                                 represent ownership of a debt instrument issued
                                 by the Company through the Pass-Through Trust.
                                 The debt instrument will have an absolute
                                 maturity corresponding to the Final
                                 Distribution Date, but will otherwise have the
                                 characteristics of the Notes, including the
                                 principal amount of and interest rate payable
                                 on the Notes. Each Certificateholder will be
                                 required to report on its federal income tax
                                 return its pro rata share of the income from
                                 the debt instrument, including interest income
                                 at the

                                 accordance with its method of accounting. The
                                 debt instrument may be issued with original
                                 issue discount. See "Certain Federal Income Tax
                                 Considerations."
 
ERISA CONSIDERATIONS..........   Each purchaser of Certificates will, by its
                                 purchase, be deemed to have directed the
                                 Trustee to purchase the Notes and to have
                                 approved all of the documents relating to the
                                 Notes, and to have represented and warranted

                                  THE COMPANY
 
   
     The Company, incorporated in Michigan in 1987, is the parent holding
company of Consumers Energy Company ("Consumers") and CMS Enterprises Company
("Enterprises"). Consumers, a combination electric and gas utility company
serving in all 68 counties of Michigan's Lower Peninsula, is the largest
subsidiary of the Company. Consumers' customer base includes a mix of
residential, commercial and diversified industrial customers, the largest
segment of which is the automotive industry. Enterprises is engaged in several
domestic and international energy-related businesses including: (i) oil and gas
exploration and production; (ii) acquisition, development and operation of
independent power production facilities; (iii) energy marketing, risk management
and energy management to large utility, commercial and industrial customers;
(iv) transmission, storage and processing of natural gas; and (v) international
energy distribution.
    
 
     The Company conducts its principal operations through the following seven
business segments: (i) electric utility operations; (ii) gas utility operations;
(iii) oil and gas exploration and production operations; (iv) independent power
production; (v) energy marketing, services and trading; (vi) natural gas
storage, transmission and processing; and (vii) international energy
distribution. Consumers or Consumers' subsidiaries are engaged in two segments:
electric operations and gas operations. Consumers' electric and gas businesses
are principally regulated utility operations.
 
   
     The Company and its subsidiaries routinely evaluate, invest in, acquire and
divest energy-related assets and/or businesses both domestically and
internationally. Consideration for such transactions may involve the delivery of
cash and/or securities.
    
 
     The Company's 1996 consolidated operating revenue was $4,333 million. This
consolidated operating revenue was derived from its electric utility operations
(approximately 57% or $2,446 million), its gas utility operations (approximately
30% or $1,282 million), gas transmission, storage and marketing (approximately
7% or $320 million), oil and gas exploration and production activities
(approximately 3% or $130 million) and independent power production and other
non-utility activities (approximately 3% or $155 million). Consumers'
consolidated operations in the electric and gas utility businesses account for
the majority of the Company's total assets, revenue and income. The
unconsolidated share of non-utility electric generation and distribution and gas
transmission and storage revenue for 1996 was $557 million.
 
     Consumers is a public utility serving gas or electricity to almost six
million of Michigan's nine and one-half million residents in all of the 68
counties in Michigan's Lower Peninsula. Consumers' service area includes
automotive, metal, chemical, food and wood products industries and a diversified
group of other industries. Consumers' 1996 consolidated operating revenue of
$3,770 million was derived approximately 65% ($2,446 million) from its electric
utility business, approximately 34% ($1,282 million) from its gas utility
business and approximately 1% ($42 million) from its non-utility business.
Consumers' rates and certain other aspects of its business are subject to the
jurisdiction of the Michigan Public Service Commission and the Federal Energy

RECENT DEVELOPMENTS
 
     On November 7, 1997, the Company issued $300 million principal amount of
7 3/8% Senior Unsecured Notes due 2000 and used the net proceeds to repay $269
million of the outstanding balance under the Company's revolving credit
facility, used $24 million to repay one of the Company's line of credit, and
used the remaining amount for general corporate purposes. On November 20, 1997,
the Company issued 4.142 million shares of CMS Energy common stock, par value
$.01 per share ("CMS Energy Common Stock") and used the proceeds for general
corporate purposes, including the repayment of long-term debt.

     On December 4, 1997, the Company and a privately held Brazilian utility,
Companhia Forca e luz Cataguazes-Leopoldina (CFLCL), announced that the
Brazilian State of Sergipe selected CFLCL as the winning bidder in the
privatization of the Energipe electric distribution utility. Energipe serves
approximately 348,000 customers in Sergipe, located in northeastern Brazil.
CFLCL submitted the winning bid of US$520.3 million for 86.4% of the ownership
interest of Energipe. CMS Electric and Gas Company, a subsidiary of the Company,
has agreed to acquire a 42.6% ownership interest in the CFLCL/Energipe combined
company for a price of approximately US$180 million and to assume an active role
in advising the company on technical matters.
    
 
   
     On December 19, 1997, the Michigan Public Service Commission issued an ex
parte order, responsive to a December 9, 1997 Consumers application, authorizing
a voluntary, experimental program that will allow up to 300,000 Michigan natural
gas customers to choose their own supplier over the next three years. The new
program will begin April 1, 1998, when 100,000 residential, commercial and
industrial retail gas sales customers of Consumers will be offered the
opportunity to participate on a first-come, first-served basis. An additional
100,000 customers will be allowed to participate in the program in each of the
following two years. During the program, Consumers' distribution service rates
for all retail gas customers will be frozen. In addition, the gas cost recovery
clause will be suspended and the gas commodity charge will be frozen at the
1996-97 rate of $2.8364 per thousand cubic feet (Mcf) for customers who remain
full-service sales customers. Finally, an earnings sharing mechanism will
provide for refunds to customers in the event that Consumer's actual gas utility
business earnings exceed certain predetermined levels.

</TABLE>
 
- -------------------------
(1) For the year ended December 31, 1992, fixed charges exceeded earnings by
    $441 million. Earnings as defined include a $520 million pretax loss on the
    settlement of MCV power purchases, $(15) million for potential customer
    refunds and other reserves related to 1992 but recorded in 1991, and $6
    million relating to CMS Generation Co.'s reduction in its investment in The
    Oxford Energy Company. The ratio of earnings to fixed charges would have
    been 1.33 excluding these amounts.
 
     For the purpose of computing such ratio, earnings represent net income
before income taxes, net interest charges and estimated interest portion of
lease rentals.
 
                                USE OF PROCEEDS
 
   
     The proceeds of the offering of the Certificates, together with the amount
payable by MSCS to the Pass-Through Trust on the date of issue of the
Certificates, will be used by the Pass-Through Trust to purchase the Notes at
par value from the Company.
    
 
   
     The net proceeds to the Company from the sale of the Notes to the
Pass-Through Trust will be used to repay certain of the Company's borrowings
under its revolving credit facility and various working capital facilities as
well as for its general corporate purposes. The revolving credit facility
matures in the year 2000, and it and the working capital facilities have a
combined weighted average interest rate at December 18, 1997 of 7.22%.
Borrowings under the revolving credit facility are funding a Company
subsidiary's acquisition of an ownership interest in a Brazilian electric
distribution company. See "Recent Developments."

                      FORMATION OF THE PASS-THROUGH TRUST
 
   
     The Pass-Through Trust is a statutory business trust formed under the
Delaware Business Trust Act pursuant to (i) a trust agreement dated as of
November 21, 1997 as to be amended and restated on the date of issue of the
Certificates, between the Company and Wilmington Trust Company, as Trustee and
(ii) the filing of a certificate of trust with the Secretary of State of the
State of Delaware on November 21, 1997. Pursuant to the Trust Agreement, the
Pass-Through Trust will issue and sell the Certificates to the Underwriters and
enter into the ISDA Master Agreement with MSCS, a wholly owned subsidiary of
Morgan Stanley, Dean Witter, Discover & Co. Under the ISDA Master Agreement, an
amount is payable by MSCS to the Pass-Through Trust on the date of issue of the
Certificates. Such amount will not be assigned for the benefit of the
Certificateholders but will be used by the Pass-Through Trust, together with the
proceeds from the sale of the Certificates, to purchase the Notes at par value
from the Company. The Notes will be the sole assets of the Pass-Through Trust
from which Certificateholders will be entitled to receive any distributions on
the Certificates. The ISDA Amount, if any, will be payable by the Pass-Through
Trust to MSCS pursuant to the ISDA Master Agreement either (i) by the Company
pursuant to the Senior Debt Indenture or (ii) in the event of a remarketing,
with the proceeds of the remarketing. Accordingly, Certificateholders will
obtain no benefit from, and will be exposed to no risk as a result of, interest
rate changes which may give rise to payment by the Company of the ISDA Amount
under the Senior Debt Indenture and in turn, the payment thereof by the Trustee
to MSCS pursuant to the ISDA Master Agreement.
    
 
                          DESCRIPTION OF CERTIFICATES
 
     The Certificates will be issued under the Trust Agreement. The following
summaries of certain provisions of the Trust Agreement do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all provisions of the Certificates and the Trust Agreement, including the
definition therein of certain terms. Wherever particular defined terms of the
Certificates and the Trust Agreement are referred to, such defined terms are
incorporated herein by reference as part of the statement made, and the
statement is qualified in its entirety by such reference. Copies of the Trust
Agreement are available from the Trustee upon request.
 
GENERAL
 
     The Certificates will represent fractional undivided beneficial interests
in the Pass-Through Trust. The sole assets (the "Trust Assets") of the
Pass-Through Trust from which Certificateholders will receive any distributions
on the Certificates will be $150,000,000 in aggregate principal amount of the
Notes issued by the Company, including the interest and Applicable Premium, if
any, thereon, but not any ISDA Amount payable in respect of the ISDA Master
Agreement. The Pass-Through Trust will acquire the Notes, which will bear
interest at the rate per annum set forth on the cover page of this Prospectus
and will mature on the Final Distribution Date unless extended as described
below. Certificateholders will be entitled to receive distributions equal to
amounts paid by the Company in respect of principal of, Applicable Premium, if
any, and interest on the Notes.
 
COLLECTIONS AND DISTRIBUTIONS
 
     The Trust Agreement will require the Trustee to establish and maintain a
segregated account (the "Certificate Account") held in trust for the benefit of
the Certificateholders. The Trustee shall cause to be deposited in the
Certificate Account on the date of receipt thereof all amounts received with
respect to the Notes other than any ISDA Amount payable in respect of the ISDA
Master Agreement.
 
     Payments of principal of, Applicable Premium, if any, and interest on the
Notes held in the Pass-Through Trust will be distributed by the Trustee to
Certificateholders on each Regular Distribution Date and each Special
Distribution Date as described in the following three paragraphs, except in
certain cases when the Notes are in default, when the Notes are redeemed in part
or when there is a Change in Control or an Excess Proceeds Offer. See
"Description of the Trust Agreement -- Events of Default," "Description of Notes
- --Optional Redemption at a Premium" and "-- Purchase of Certificates upon Change
in Control or Excess

Proceeds Offer." Interest paid on the Notes will be passed through to the
Certificateholders on           and           of each year, commencing on
          , 1998, until the Final Distribution Date for the Pass-Through Trust
(each, a "Regular Distribution Date"). Payment of principal on the Notes is
scheduled to be received by the Trustee not later than the Final Distribution
Date (such scheduled payments of the principal amount of and interest on the
Notes are herein referred to as "Scheduled Payments").
    
 
     The Trustee will distribute on each Regular Distribution Date all Scheduled
Payments the receipt of which is confirmed by the Trustee on such date. Each
Certificateholder will be entitled to receive a pro rata share of any
distribution in respect of Scheduled Payments made on the Notes. Each such
distribution in respect of Scheduled Payments will be made by the Trustee to the
holders of record of the Certificates on the first day, whether or not a
Business Day, of the calendar month in which such Regular Distribution Date
occurs, except that no record date shall be applicable to distributions to be
made on the Final Distribution Date. If a Scheduled Payment is not received by
the Trustee on a Regular 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 below.
 
     Payments of principal of, Applicable Premium and interest on the Notes
received by the Trustee on account of an optional redemption, if any, of all of
the Notes, and payments received by the Trustee following an Event of Default
("Special Payments") will be distributed on, in the case of an early redemption,
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) (each, a "Special Distribution Date"). 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. See
"Description of Notes -- Optional Redemption at a Premium" and "Description of
the Trust Agreement -- Events of Default."
 
     The Notes will be prepaid on a Special Distribution Date at a price equal
to the principal amount of, interest on, and Applicable Premium, if such
redemption occurs on or prior to the Premium Termination Date. If less than all
of the Notes are to be redeemed, the Trustee shall select, in such manner as it
shall deem appropriate and fair, the particular Certificates or portions thereof
representing beneficial ownership of the Notes to be redeemed. Upon a redemption
of less than all of the Notes, Certificates representing beneficial ownership of
the Notes selected for redemption will be required to be presented to the
Trustee for cancellation. Upon such presentation, all payments of principal of,
Applicable Premium, if any, and interest on the Notes paid by the Company to the
Pass-Through Trust will be distributed to the holders of such Certificates. The
ISDA Amount will be distributed to MSCS. See "Description of Notes -- Optional
Redemption at a Premium" for a description of the manner of computing the
Applicable Premium, if any.
 
FINAL DISTRIBUTION
 
   
     The Final Distribution on the Certificates, representing an amount equal to
the principal of and interest on the Notes, assuming the Notes have been held
until the Final Distribution Date, is expected to be made on the Final
Distribution Date. If the Yield on the Exercise Date is equal to or greater than
the reference U.S. Treasury Note yield of      % used to determine the interest
rate per annum borne by the Notes as set forth on the cover page of this
Prospectus, the Notes will mature on the Final Distribution Date. If the Yield
on the Exercise Date is less than such reference U.S. Treasury Note yield the
maturity of the Notes will be extended and, prior to the Final Distribution
Date, one of the following will occur: (a) the interest rate borne by the Notes
will be reset and the Notes will be remarketed so as to yield net proceeds in
cash at least equal to the Remarketing Proceeds which, together with the amount
payable by the Company representing interest on the Notes through the Final
Distribution Date, will be sufficient to enable the Trustee to make the Final
Distribution on the Certificates, (b) the Company will exercise its option to
redeem the Notes on the Final Distribution Date at a purchase price equal to the
principal amount of and interest on the Notes plus the
    
 
                                       16
<PAGE>   18
 
   
ISDA Amount or (c) the Pass-Through Trust will exercise its Put Option and
require the Company to purchase the Notes on the Final Distribution Date at a
purchase price equal to the principal amount of and interest on the Notes. In
any case, the principal of and interest on the Notes will be distributed by the
Pass-Through Trust to the Certificateholders on the Final Distribution Date. The
ISDA Amount (if any) will be distributed to MSCS.
    
 
     "Yield" shall mean the yield-to-maturity on the then current 7-year U.S.
Treasury Note as determined by linear interpolation of the 5-year and 10-year
then current offered-side yields for the on-the-run most recently issued U.S.
Treasury Notes, as published on Telerate page 500 as of approximately 12:30
p.m., New York City time, on the Exercise Date. If Telerate 500 is unavailable,
"Yield" shall be the arithmetic mean of offered-side yields for the then current
7-year U.S. Treasury Note as determined by linear interpolation of the 5-year
and 10-year then current offered-side yields for the on-the-run most recently
issued U.S. Treasury Notes, without regards to highest and lowest yields, quoted
as of approximately 12:30 p.m., New York City time, on the Exercise Date by five
primary dealers in U.S. Treasury Notes selected by MSCS.
 
     MSCS will deliver notice of the extension of the maturity of the Notes (the
"Extension Notice") to both the Trustee and the Company at their respective
addresses set forth herein on or prior to the Exercise Date.
 
     Final Distribution upon a Successful Remarketing
 
   
     If the maturity of the Notes is extended, unless the Company exercises its
option to redeem the Notes (which option the Company may 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), the interest rate
borne by the Notes will be reset in order that the Notes may be remarketed so as
to yield net proceeds in cash equal to the Remarketing Proceeds. On the Exercise
Date and once every 15 days thereafter, 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 and discount or premium at which it
believes it could remarket the Notes. The Company may then, on behalf of the
Pass-Through Trust, either request that Morgan Stanley & Co. Incorporated
remarket the Notes, select another investment banking institution to remarket
the Notes or exercise the option to redeem the Notes. Regardless of whether it
has been selected to act as remarketing agent, Morgan Stanley & Co. Incorporated
shall at all times be permitted to offer to purchase the Notes bearing a reset
interest rate specified by Morgan Stanley & Co. Incorporated for net proceeds in
cash at least equal to the Remarketing Proceeds, which offer the Company and the
Trustee shall be required to accept, unless (i) any other party shall have
remarketed the Notes bearing an interest rate less than or equal to that
specified by Morgan Stanley & Co. Incorporated and for net proceeds in cash at
least equal to the Remarketing Proceeds or (ii) the Company exercises its option
to redeem all of the Notes on the Final Distribution Date at a purchase price
equal to the principal amount of and interest on the Notes plus the ISDA Amount.
Upon the closing of any remarketing, the portion of the proceeds representing
principal of the Notes, together with the amount paid by the Company
representing interest on the Notes through the Final Distribution Date, will be
deposited with the Trustee for distribution to Certificateholders, and the
portion of the proceeds representing the ISDA Amount will be distributed to
MSCS.
    
 
     Final Distribution upon Optional Redemption of the Notes without Premium
 
   
     If the maturity of the Notes is extended, the Company may, in lieu of
permitting the Notes to be remarketed, exercise its option to redeem all of the
Notes on the Final Distribution Date at a purchase price equal to the principal
amount of and interest on the Notes plus the ISDA Amount, but without the
Applicable Premium. The Company may exercise this option 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. The principal of and interest
on the Notes paid by the Company to the Pass-Through Trust will be distributed
to the Certificateholders on the Final Distribution Date. The ISDA Amount will
be distributed to MSCS.
    
 
                                       17
<PAGE>   19
 
     Final Distribution upon Exercise by the Trustee of Put Option
 
     If the maturity of the Notes is extended and for any reason the Trustee
does not receive an amount in cash equal to the principal amount of and interest
on the Notes by the Remarketing Deadline, the Pass-Through Trust will be deemed
to have exercised its Put Option and required the Company to purchase the Notes
on the Final Distribution Date at a purchase price equal to the principal amount
of and interest on the Notes. All payments in respect of the Notes paid by the
Company to the Pass-Through Trust upon exercise of the Put Option will be
distributed to Certificateholders on the Final Distribution Date.
 
PURCHASE OF CERTIFICATES UPON CHANGE IN CONTROL OR EXCESS PROCEEDS OFFER
 
     Change in Control
 
     In the event of any Change in Control (as defined below) (the effective
date of such change in control being the "Change in Control Date") each
Certificateholder will have the right, at such Certificateholder's option,
subject to the terms and conditions of the Trust Agreement, to direct the
Trustee to require the Company to repurchase all or any part of the Notes
beneficially owned by such Certificateholder on a date selected by the Company
that is no earlier than 60 days nor later than 90 days (the "Change in Control
Purchase Date") after the mailing of written notice by the Company of the
occurrence of such Change in Control at a repurchase price payable in cash equal
to 101% of the principal amount of such Notes, together with accrued interest to
the Change in Control Purchase Date (the "Change in Control Purchase Price"),
plus the ISDA Amount. Upon receipt of any payments on the Notes by the
Pass-Through Trust pursuant to a Change in Control, the Trustee will pay the
Change in Control Purchase Price to the Certificateholders who directed the
Trustee to require the Company to repurchase all or any part of the Notes
beneficially owned by them upon presentation for cancellation of the related
Certificates. The ISDA Amount will be distributed to MSCS.
 
     Within 30 days after the Change in Control Date, the Company is obligated
to mail to each Certificateholder a notice regarding the Change in Control,
which notice shall state: (i) that a Change in Control has occurred and that
each such Certificateholder has the right to direct the Trustee to require the
Company to repurchase all or any part of the Notes 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 Change in Control Purchase Date; (iv) the name and address of
the Paying Agent (as defined) for the Notes; and (v) the procedures that
Certificateholders must follow to cause the Notes beneficially owned by such
Certificateholder to be repurchased by the Company.
 
     To exercise this right, a Certificateholder must deliver a written notice
(the "Change in Control Purchase Notice") to the Paying Agent at its corporate
trust office in Detroit, Michigan, or any other office of the 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, among
other things, (i) the portion of the principal amount of any Notes beneficially
owned by such Certificateholder to be repurchased, which must be $1,000 or an
integral multiple thereof; and (ii) that such Notes are to be repurchased by the
Company pursuant to the applicable change-in-control provisions of the Senior
Debt Indenture and the Trust Agreement.
 
     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 Notes
beneficially owned by such Certificateholder and, if applicable, the certificate
numbers of the Certificates as to which the withdrawal notice relates and the
principal amount, if any, which remains subject to a Change in Control Purchase
Notice.
 
     If a Certificate is represented by a Global Certificate, the Depositary (as
defined) or its nominee will be the holder of such Certificate and therefore
will be the only entity that may require the Company to repurchase Notes upon a
Change in Control. To obtain repayment with respect to any Note upon a Change in
Control, the beneficial owner of the Certificate evidencing beneficial ownership
of such Note must provide to the broker or other entity through which it holds
the beneficial interest in such Certificate (i) the Change in
 
                                       18
<PAGE>   20
 
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. ("NASD") 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 cause the Company to repurchase such Notes
beneficially owned by such Certificateholder. Such broker or other entity will
provide to the Paying Agent (i) a Change in Control Purchase Notice received
from such beneficial owner and (ii) a certificate satisfactory to the Paying
Agent from such broker or other entity that it represents such beneficial owner.
Such broker or other entity will be responsible for disbursing any payments it
receives upon the repurchase of such Notes by the Company.
 
     Payment of the Change in Control Purchase Price for Notes in respect of a
Certificate in certificated form (a "Definitive Certificate") for which a Change
in Control Purchase Notice has been delivered and not withdrawn is conditioned
upon delivery of such Definitive Certificate (together with necessary
endorsements) to the Paying Agent at its office in Detroit, Michigan, or any
other office of the 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 Notice. Payment of the Change in
Control Purchase Price for Notes in respect of such Definitive Certificate will
be made promptly following the later of the Change in Control Purchase Date or
the time of presentation for cancellation of such Definitive Certificate.
 
     If the Paying Agent holds, in accordance with the terms of the Senior Debt
Indenture, money sufficient to pay the Change in Control Purchase Price of Notes
in respect of a Certificate on the Business Day following the Change in Control
Purchase Date for such Certificate, then, on and after such date, interest on
such Note will cease to accrue, whether or not such Certificate is delivered to
the 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 Certificate).
 
     Under the Senior Debt Indenture, a "Change in Control" means an event or
series of events by which (i) the Company ceases to beneficially own, directly
or indirectly, at least 80% of the total voting power of all classes of Capital
Stock then outstanding of Consumers (whether arising from issuance of securities
of the Company or Consumers, any direct or indirect transfer of securities by
the Company or Consumers, any merger, consolidation, liquidation or dissolution
of the Company or Consumers or otherwise); or (ii) any "person" or "group" (as
such terms are used in Sections 13(d) and 14(d) of the Exchange Act) becomes the
"beneficial owner" (as such term is used in Rules 13d-3 and 13d-5 under the
Exchange Act, except that a person or group shall be deemed to have "beneficial
ownership" of all shares that such person or group has the right to acquire,
whether such right is exercisable immediately or only after the passage of
time), directly or indirectly, of more than 35% of the Voting Stock (as defined)
of the Company; or (iii) the Company consolidates with or merges into another
corporation or directly or indirectly conveys, transfers or leases all or
substantially all of its assets to any person, or any corporation consolidates
with or merges into the Company, in either event pursuant to a transaction in
which the outstanding Voting Stock of the Company is changed into or exchanged
for cash, securities, or other property, other than any such transaction where
(A) the outstanding Voting Stock of the Company is changed into or exchanged for
Voting Stock of the surviving corporation and (B) the holders of the Voting
Stock of the Company immediately prior to such transaction retain, directly or
indirectly, substantially proportionate ownership of the Voting Stock of the
surviving corporation immediately after such transaction.
 
     The Trust Agreement and the Senior Debt Indenture require the Company to
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 purchase Notes beneficially owned by Certificateholders at the
option of Certificateholders upon a Change in Control. The Change in Control
purchase feature of the Certificates may in certain circumstances make more
difficult or discourage a takeover of the Company and, thus, the removal of
incumbent management. The Change in Control purchase feature, however, is not
the result of management's knowledge of any specific effort to accumulate shares
of its common stock or to obtain control of the Company by means of a merger,
tender offer, solicitation or otherwise, or part of a plan by management to
adopt a series of antitakeover provisions. Instead, the Change in Control
purchase feature is a term contained in many similar debt offerings and the
terms of such feature result from negotiations between
 
                                       19
<PAGE>   21
 
   
the Company and the Underwriters. Management has no present intention to propose
any antitakeover measures although it is possible that the Company could decide
to do so in the future.
    
 
     No Note may be repurchased by the Company as a result of a Change of
Control if there has occurred and is continuing an Event of Default described
under "Description of the Trust Agreement -- Events of Default" (other than a
default in the payment of the Change in Control Purchase Price with respect to
the Notes). In addition, the Company's ability to purchase Notes may be limited
by its financial resources and its inability to raise the required funds because
of restrictions on issuance of securities contained in other contractual
arrangements.
 
     Excess Proceeds Offer
 
   
     Under the terms of the Senior Debt Indenture, so long as any of the Notes
are outstanding, the Company may not sell, transfer or otherwise dispose of any
property or assets of the Company, including Capital Stock of any Consolidated
Subsidiary, in one transaction or a series of transactions in an amount which
exceeds $50,000,000 (an "Asset Sale") unless the Company shall (i) apply an
amount equal to such excess Net Cash Proceeds to permanently repay Indebtedness
of a Consolidated Subsidiary or Indebtedness of the Company which is pari passu
with the Notes or (ii) invest an equal amount not so used in clause (i) in
property or assets of related business within 24 months after the date of the
Asset Sale (the "Application Period") or (iii) apply such excess Net Cash
Proceeds not so used in (i) or (ii) (the "Excess Proceeds") to make an offer,
within 30 days after the end of the Application Period, to purchase on a pro
rata basis an aggregate principal amount of Notes on the relevant purchase date
equal to the Excess Proceeds on such date, at a purchase price equal to 100% of
the principal amount of the Notes on the relevant purchase date and unpaid
interest, if any, to the purchase date (the "Excess Proceeds Purchase Price")
plus the ISDA Amount, if any (an "Excess Proceeds Offer"). The Company shall
only be required to make an Excess Proceeds Offer if the Excess Proceeds equal
or exceed $25,000,000 at any given time.
    
 
     The procedures to be followed by the Company in making an offer to the
Trustee on behalf of Certificateholders to purchase Notes with Excess Proceeds
and to pay the Excess Proceeds Purchase Price therefor, and the directions to
the Trustee by Certificateholders to accept such offer with respect to
Certificates beneficially owned by them, shall be the same as those set forth
above in with respect to a Change in Control and payment of the Change of
Control Purchase Price.
 
BOOK-ENTRY; DELIVERY AND FORM
 
     The certificates representing the Certificates will be issued in fully
registered form without interest coupons and will be represented by one or more
permanent global Certificates in definitive, fully registered form without
interest coupons (each, a "Global Certificate") and will be deposited with the
Trustee as custodian for, and registered in the name of, a nominee of DTC. Each
Global Certificate (and any Certificates issued in exchange therefor) will be
subject to certain restrictions on transfer set forth therein as described under
"Transfer Restrictions." Except in the limited circumstances described below,
owners of beneficial interests in a Global Certificate will not be entitled to
receive physical delivery of Definitive Certificates.
 
     The Certificates will be sold in minimum denominations of $250,000.
 
     Ownership of beneficial interests in a Global Certificate will be limited
to persons who have accounts with DTC ("participants") or persons who hold
interests through participants. Ownership of beneficial interests in a Global
Certificate will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants).
 
     So long as DTC, or its nominee, is the registered owner or holder of a
Global Certificate, DTC or such nominee, as the case may be, will be considered
the sole owner or holder of the Certificates represented by such Global
Certificate for all purposes under the Trust Agreement and the Certificates. No
beneficial owner of an interest in a Global Certificate will be able to transfer
that interest except in accordance with DTC's applicable procedures, in addition
to those provided for under the Senior Debt Indenture.
 
                                       20
<PAGE>   22
 
     Payments of the principal amount, premium, if any, and interest on, a
Global Certificate will be made to DTC or its nominee, as the case may be, as
the registered owner thereof. Neither the Company nor the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global
Certificate or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
     The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Certificate, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global
Certificate as shown on the records of DTC or its nominee. The Company also
expects that payments by participants to owners of beneficial interests in such
Global Certificate held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers registered in the names of nominees for such
customers. Such payments will be the responsibility of such participants.
 
     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds.
 
     The Company expects that DTC will take any action permitted to be taken by
a Certificateholder (including the presentation of Certificates for exchange as
described below) only at the direction of one or more participants to whose
account or accounts the DTC interests in a Global Certificate is credited and
only in respect of such portion of the aggregate principal amount of the
Certificate as to which such participant or participants has or have given such
direction. However, if there is an Event of Default under the Certificates, DTC
will exchange the applicable Global Certificate for Definitive Certificates,
which it will distribute to its participants and which may be legended as set
forth under the heading "Transfer Restrictions."
 
     The Company understands that DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its participants
and facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry charges in accounts of its
participants, thereby eliminating the need for physical movement of certificates
and certain other organizations. Indirect access to the DTC system is available
to others such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly ("Indirect Participants").
 
     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in a Global Certificate among participants of
DTC, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Company nor the Trustee will have any responsibility for the performance by DTC
or its respective participants or indirect participants of its respective
obligations under the rules and procedures governing their operations.
 
EXCHANGE OF BOOK-ENTRY CERTIFICATES FOR DEFINITIVE CERTIFICATES
 
     If DTC is at any time unwilling or unable to continue as depositary and a
successor depositary is not appointed by the Company within 90 days, the
Pass-Through Trust will issue individual, fully registered, definitive
Certificates in exchange for the Global Certificate or Certificates representing
such Definitive Certificates. Upon the exchange of a Global Certificate for
Definitive Certificates, such Global Certificate shall be cancelled by the
Trustee and the Definitive Certificates shall be registered in such names and in
such authorized denominations as DTC, pursuant to instructions from its
Participants, any Indirect Participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such Certificates to the persons in whose
names such Certificates are so registered and shall recognize such persons as
Certificateholders.
 
     Definitive Certificates will bear, and be subject to, the legend described
in "Transfer Restrictions" (unless the Company determines otherwise in
accordance with applicable law). The holder of a Definitive Certificate may
transfer such Certificate, subject to compliance with the provisions of such
legend, as provided herein.

                       DESCRIPTION OF THE TRUST AGREEMENT
 
     The following summaries of certain provisions of the Trust Agreement do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all provisions of the Trust Agreement, including the definition
therein of certain terms. Wherever particular defined terms of the Trust
Agreement are referred to, such defined terms are incorporated herein by
reference as part of the statement made, and the statement is qualified in its
entirety by such reference. Copies of the Trust Agreement are available from the
Trustee upon request.
 
GENERAL
 
   
     Pursuant to the Trust Agreement, the Pass-Through Trust will issue and sell
the Certificates to the Underwriters and enter into the ISDA Master Agreement.
Under the ISDA Master Agreement, an amount is payable by MSCS to the
Pass-Through Trust on the date of issue of the Certificates. Such amount will
not be assigned for the benefit of the Certificateholders but will be used by
the Pass-Through Trust, together with the proceeds from the sale of the
Certificates, to purchase the Notes at par value from the Company. The Notes
will be the sole assets of the Pass-Through Trust from which Certificateholders
will be entitled to receive any distributions on the Certificates. The ISDA
Amount, if any, payable by the Pass-Through Trust to MSCS pursuant to the ISDA
Master Agreement will be payable either (i) by the Company pursuant to the
Senior Debt Indenture or (ii) in the event of a remarketing, with the proceeds
of the remarketing. Accordingly, Certificateholders will obtain no benefit from,
and will be exposed to no risk as a result of, interest rate changes which may
give rise to payment by the Company of the ISDA Amount under the Senior Debt
Indenture and in turn, the payment thereof by the Trustee to MSCS pursuant to
the ISDA Master Agreement.
    
 
THE TRUSTEE
 
     Wilmington Trust Company will act as Trustee for the Certificates and the
Pass-Through Trust pursuant to the Trust Agreement. The Trustee's offices are
located at 1100 North Market Street, Wilmington, Delaware 19890-0001.
 
     The Trust Agreement provides that the Company will, to the fullest extent
permitted by law, indemnify and hold harmless the Trustee against any loss,
damage, claim, liability, penalty or expense incurred by the Trustee arising out
of or in connection with the administration of the Trust Agreement, the
Certificates, the ISDA Master Agreement or the Underwriting Agreement (as
defined) except to the extent that such loss, liability or expense is due to
wilful misconduct, bad faith or negligence of the Trustee.
 
     Pursuant to the Trust Agreement, as compensation for the performance of its
duties under such agreement, the Company will pay such compensation as the
Company and the Trustee shall agree in writing, and except as otherwise agreed
to, the Trustee, upon its request, shall be entitled to be reimbursed by the
Company for any reasonable expenses, except any such expenses as may be
attributable to wilful misconduct, bad faith or negligence, or as may be
incurred due to the Trustee's breach of its representations and warranties under
the Trust Agreement.
 
ADMINISTRATIVE PROCEDURES
 
     The Trustee shall administer the Trust Assets for the benefit of the
Certificateholders. Except as provided in the Trust Agreement, the Trustee shall
have full power and authority to do or cause to be done any and all things in
connection with the administration of the Pass-Through Trust which it deems
necessary to comply with the terms of the Trust Agreement.
 
EVENTS OF DEFAULT
 
     An event of default with respect to the Certificates shall occur upon an
event of default under the Notes (an "Event of Default"). See "Description of
Notes -- Events of Default."
 
     If an Event of Default occurs and continues resulting in acceleration of
the Notes, then the Trustee may vote the Notes, and upon the direction of a
majority of Certificateholders, the Trustee shall vote in favor of
 
                                       22
<PAGE>   24
 
   
directing the Indenture Trustee to declare the unpaid principal amount of the
Notes then outstanding and interest, if any, due and payable. Amounts paid by
the Company to the Pass-Through Trust in respect of (i) the principal amount of
and interest on the Notes will be distributed to the Certificateholders as a
Special Payment on a Special Distribution Date and (ii) the ISDA Amount, if any,
as of the date of the Event of Default will be distributed to MSCS. If in
connection with any such Event of Default the amounts paid by the Company to the
Pass-Through Trust in respect of the foregoing clauses (i) and (ii) are less
than the amounts due, the amounts received by the Pass-Through Trust will be
distributed on a pro rata basis to the Certificateholders, on the one hand, and
MSCS, on the other; provided that no such distribution shall effect the right of
the Trustee to demand and receive payment in full of all amounts due from the
Company.
    
 
VOTING RIGHTS
 
     Each Certificateholder shall be entitled to direct the Trustee to vote a
principal amount of the Notes corresponding to the principal amount of the
Certificates held by such Certificateholder in the manner directed by the
Certificateholder (the "Voting Rights"). The Trust Agreement contains minimum
aggregate voting requirements for certain actions including, among other things,
actions by the Trustee, removal of the Trustee, amendment of the Trust Agreement
and commencement of claims under the Trust Agreement. Without the consent of all
Certificateholders, no amendment may be made to the Trust Agreement which
reduces the percentage of Voting Rights required to modify the Trust Agreement
in a way which adversely affects in any material respect the interests of
Certificateholders. See "-- Amendment of the Trust Agreement."
 
VOTING OF NOTES
 
     The Trustee, as holder of the Notes, has the right to vote and give
consents and waivers in respect of the Notes and enforce such other rights of a
holder of the Notes except as otherwise limited by the Trust Agreement or the
Senior Debt Indenture. In the event that the Trustee, as holder of any Notes,
receives a request from the Company or, if applicable, any depositary with
respect to the Notes, for the Trustee's consent to any amendment, modification
or waiver of the Senior Debt Indenture, or any document thereunder, or relating
thereto, or receives any other solicitation for any action with respect to the
Notes, the Trustee shall within five Business Days mail a notice of such
proposed amendment, modification, waiver or solicitation to each
Certificateholder of record as of the date of such request. The Trustee shall
request instructions from the Certificateholders as to what action to take in
response to such request. Except as otherwise provided in the Trust Agreement,
the Trustee shall consent or vote, or refrain from consenting or voting, in the
same proportion as the Certificates were actually voted or not voted by the
holders thereof as of the date determined by the Trustee prior to the date such
vote or consent as a Certificateholder of Notes is required; provided, however,
that, the Trustee shall at no time, without the consent of each
Certificateholder, vote in favor of or consent to any matter (i) unless such
vote or consent would not, based on an opinion of counsel, alter the status of
the Pass-Through Trust as a grantor trust under the Code or result in an actual
or constructive sale or exchange of any Note for tax purposes, (ii) which would
alter the timing or amount of any payment on the Notes, or (iii) which would
result in the exchange or substitution of any Notes pursuant to a plan for the
refunding or refinancing of such Notes, 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.
 
TERMINATION OF OBLIGATIONS UNDER THE PASS-THROUGH TRUST
 
     The respective obligations of the Company and the Trustee under the Trust
Agreement which are for the benefit of Certificateholders shall cease upon the
completion of the Final Distribution to Certificateholders.
 
AMENDMENT OF THE TRUST AGREEMENT
 
   
     The Trust Agreement may be amended from time to time by the Company and the
Trustee without notice to or the consent of any of the Certificateholders for
any of the following purposes: (i) to evidence the succession of another
corporation to the Company and the assumption by any such successor of the
covenants
    
 
                                       23

of the Company contained in the Trust Agreement; (ii) to add to the covenants,
restrictions or obligations of the Company or the Trustee; (iii) to add or
supplement any security for the benefit of any Certificateholders; (iv) to cure
any ambiguity or to correct or supplement any provision which may be defective
or inconsistent with any other provision in the Trust Agreement, the Senior Debt
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 Trust Agreement, provided that no such action materially
adversely affects the interests of any Certificateholders; (v) to modify,
eliminate or add to the provisions of the Trust Agreement to such extent as
shall be necessary to continue the qualification of the Trust Agreement under
the Trust Indenture Act, or under any similar federal statute hereafter enacted,
and to add such other provisions as expressly permitted by the Trust Indenture
Act, with certain exceptions; (vi) to evidence and provide for the acceptance of
appointment of a Trustee other than Wilmington Trust Company, and to add to or
change any of the provisions of the Trust Agreement as shall be necessary to
provide for or facilitate the administration of the Pass-Through Trust; (vii) to
provide certain information as to the Trustee as required under the Trust
Agreement; (viii) to modify or amend any provision of the Trust 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 (ix) to comply with any requirements imposed by the Code;
provided further that no such amendment referred to in the foregoing clauses (i)
through (ix) which has a material adverse effect on MSCS may be entered into
without the consent of MSCS, and no such amendment, as evidenced by an opinion
of counsel, shall alter the status of the Pass-Through Trust as a grantor trust
under the Code or result in an actual or constructive sale or exchange of any
Certificate for tax purposes. The Trustee is entitled to receive, and may rely
upon, an opinion of counsel with respect to any amendment.
 
     The Trust Agreement also permits the Company and the Trustee, with the
consent of the Certificateholders of not less than a majority in aggregate
principal amount of the Certificates then Outstanding, to enter into agreements,
to add any provisions to, or change in any manner or eliminate any of the
provisions of, the Trust Agreement or modify in any manner the rights of the
Certificateholders; provided, however, that the Company and the Trustee may not,
without the consent of each Certificateholder affected thereby, enter into such
agreement (i) which would alter the timing or amount of any payment on the
Certificates or changes the place of payment where, or the coin or currency in
which, any Certificate is payable, or impairs the right to institute for the
enforcement of any such payment or distribution on or after the Regular
Distribution Date or Special Distribution Date applicable thereto, (ii) permits
the disposition of any Notes, except as permitted by the Trust Agreement, or
otherwise deprives the Certificateholder of the benefit of ownership of the
Notes in the Trust, (iii) reduces the percentage of the aggregate fractional
undivided interest in the Notes that is evidenced by a Certificate which is
required for any supplemental agreement which adversely affects in any material
respects the interests of the Certificateholders, or reduces such percentage
required for any waiver of compliance with certain provisions or certain
defaults of the Trust Agreement, (iv) modifies any of the provisions relating to
"supplemental agreements with consent of certificateholders" and "waiver of past
defaults" contained in the Trust Agreement, except to increase such percentage
or to provide that certain provisions cannot be waived or modified without
consent of the Certificateholder, or (v) which would result in the exchange or
substitution of any Certificates pursuant to a plan for the refunding or
refinancing of such Certificates; provided further that no amendment referred to
in the foregoing clauses (i) through (v) which has a material adverse effect on
MSCS may be entered into without the consent of MSCS and unless such vote or
consent would not, based on an opinion of counsel, alter the status of the
Pass-Through Trust as a grantor trust under the Code or result in an actual or
constructive sale or exchange of any Note for tax purposes.
 
REPORTS TO CERTIFICATEHOLDERS
 
     Within the prescribed period of time for tax reporting purposes after the
end of each calendar year, the Trustee shall furnish, or cause to be furnished,
to each person who at any time during such calendar year shall have been a
holder of record of Certificates and received any payment thereon, a statement
containing such information as may be required by the Code and applicable
Treasury Regulations to enable such person to prepare its federal income tax
returns.
 
                                       24

MODIFICATION OF OTHER AGREEMENTS
 
     Certain provisions of the Senior Debt Indenture and the ISDA Master
Agreement may be modified, amended or supplemented by the parties thereto
without the consent of the Certificateholders or MSCS so long as such
modification, amendment or supplement does not have a material adverse effect on
the Certificateholders or MSCS, as the case may be. See "Description of Notes --
Modification of the Senior Debt Indenture."
 
NOTICES TO DEPOSITARY
 
     Whenever a notice or other communication to Certificateholders whose
ownership is evidenced by one or more Global Certificates is required under the
Trust Agreement, unless and until Definitive Certificates shall have been issued
to such Certificateholders pursuant to the Trust Agreement, the Trustee shall
give all such notices and communications specified to be given to
Certificateholders to DTC or a successor depositary, and shall have no
obligation to the Certificateholders.
 
REPLACEMENT CERTIFICATES
 
     If the Trustee receives evidence of the mutilation, destruction, loss or
theft of any Certificate, and there is delivered to the Trustee such security,
indemnity or bond as it may require to hold it and any Paying Agent harmless,
and the Trustee has not received notice that such Certificate has been acquired
by a bona fide purchaser, then, upon payment by the holder of any applicable
expenses, the Trustee shall execute and authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Certificate a
new Certificate or Certificates of like tenor, form, terms and principal amount.
 
GOVERNING LAW
 
     The Trust Agreement and the Certificates will be governed by, and construed
in accordance with, the laws of the State of Delaware.
 
                              DESCRIPTION OF NOTES
 
   
     The Notes will be issued as a series of securities under the Indenture
dated as of September 15, 1992, as previously supplemented and as further
supplemented by a Sixth Supplemental Indenture establishing the Notes dated as
of           , 1998 between the Company and NBD Bank, as Trustee. The Indenture
and the Supplemental Indenture are hereinafter referred to collectively as the
"Senior Debt Indenture." The following summaries of certain provisions of the
Senior Debt Indenture do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, all provisions of the Senior Debt
Indenture, including the definitions therein of certain terms. Wherever
particular defined terms of the Senior Debt Indenture are referred to, such
defined terms are incorporated herein by reference as part of the statement
made, and the statement is qualified in its entirety by such reference. Copies
of the Senior Debt Indenture are available from the Indenture Trustee upon
request.
    
 
GENERAL
 
     The Notes will be limited in aggregate principal amount to $150,000,000.
Unless the Company redeems the Notes or the maturity of the Notes is extended
(see "Description of Certificates -- Final Distribution"), the entire principal
amount of the Notes will mature and become due and payable, together with
accrued and unpaid interest thereon, if any, on           , 2005.
 
   
     The Senior Debt Indenture does not limit the aggregate principal amount of
debt securities that may be issued thereunder and provides that debt securities
may be issued thereunder, from time to time, in one or more series. The Notes
and all other debt securities hereafter issued under the Senior Debt Indenture
are collectively referred to herein as the "Senior Debt Securities."
    
 
                                       25
<PAGE>   27
 
     The Notes will be unsecured debt securities of the Company. As of September
30, 1997, the Company had outstanding approximately $1.984 billion aggregate
principal amount of indebtedness, none of which was secured. None of such
indebtedness would be senior to the Notes and the Notes will not be senior to
any such indebtedness, except that the Notes will be senior to certain
subordinated debentures in an aggregate principal amount of $178,000,000, issued
in connection with certain preferred securities of a subsidiary trust. The Notes
will rank pari passu in right of payment with all other unsecured and
unsubordinated indebtedness of the Company.
 
     The Company is a holding company and its assets consist primarily of
investments in its subsidiaries. The Notes will be obligations exclusively of
the Company. The Company's ability to service its indebtedness, including the
Notes, is dependent primarily upon the earnings of its subsidiaries and the
distribution or other payment of such earnings to the Company in the form of
dividends, loans or advances, and repayment of loans and advances from the
Company. The subsidiaries are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amounts due pursuant to the
Notes or to make any funds available therefor, whether by dividends, loans or
other payments.
 
     A substantial portion of the consolidated liabilities of the Company have
been incurred by its subsidiaries. Therefore, the Company's rights and the
rights of its creditors, including Holders (as defined) of Notes, to participate
in the distribution of assets of any subsidiary upon the latter's liquidation or
reorganization will be subject to prior claims of the subsidiary's creditors,
including trade creditors, except to the extent that the Company may itself be a
creditor with recognized claims against the subsidiary (in which case the claims
of the Company would still be subject to the prior claims of any secured
creditor of such subsidiary and of any holder of indebtedness of such subsidiary
that is senior to that held by the Company). As of September 30, 1997, the
Company's subsidiaries had total indebtedness for borrowed money (excluding
intercompany indebtedness) of approximately $2.780 billion.
 
INTEREST
 
   
     Interest on the Notes will accrue from           , 1998 and be payable in
cash on each Regular Distribution Date, commencing           , 1998, at the rate
per annum set forth on the cover page of this Prospectus. Such interest will be
computed on the basis of a 360-day year of twelve 30-day months.
    
 
     In any case where any interest payment date, repurchase date or maturity of
any Note shall not be a Business Day (as defined) at any place of payment, then
payment of the principal amount of, premium, if any, and interest on the Notes
need not be made at such place of payment on such date, but may be made on the
next succeeding Business Day at such place of payment with the same force and
effect as if made on the interest payment date, repurchase date or at maturity;
and no interest shall accrue on the amount so payable for the period from and
after such interest payment date, redemption date, repurchase date or maturity,
as the case may be, to such Business Day.
 
OPTIONAL REDEMPTION AT A PREMIUM
 
     The Notes will be redeemable at any time, at the option of the Company, in
whole or in part, on not less than 30 nor more than 60 days' prior notice by the
Company to the Indenture Trustee, the Trustee and MSCS, at a redemption price
equal to the sum of (a) 100% of the principal amount of the Notes being
redeemed, interest, if any, thereon to the redemption date, and the Applicable
Premium if such redemption occurs on or prior to the Premium Termination Date,
plus (b) the ISDA Amount. In no event will the redemption price calculated
pursuant to the foregoing clause (a) ever be less than 100% of the principal
amount of the Notes to be redeemed plus accrued interest to the redemption date.
All payments of principal of, Applicable Premium and interest on the Notes paid
by the Company to the Pass-Through Trust with respect to a redemption in whole
will be distributed to the Certificateholders on a Special Distribution Date,
which shall be the redemption date of such Notes. The ISDA Amount will be
distributed to MSCS.
 
   
     If less than all of the Notes are to be redeemed, the Trustee shall select,
in such manner as it shall deem appropriate and fair, the particular
Certificates or portions thereof representing beneficial ownership of the Notes
to be redeemed. Notice of redemption shall be given by mail not less than 20 nor
more than 60 days
    
 
                                       26
<PAGE>   28
 
   
prior to the date fixed for redemption to the Holders whose Notes are to be
redeemed; provided, however, that the failure to duly give such notice by mail,
or any deficit therein, shall not affect the validity of any proceedings for the
redemption of Notes as to which there shall have been no such failure or defect.
On and after the date fixed for redemption (unless the Company shall default in
the payment of the Notes or portions thereof to be redeemed at the applicable
redemption price, interest on the Notes or the portions thereof so called for
redemption shall cease to accrue. Certificates representing beneficial ownership
of the Notes selected for partial redemption will be required to be presented to
the Trustee for cancellation. Upon such presentation, all payments of principal
of, Applicable Premium, if any, and interest on the Notes paid by the Company to
the Pass-Through Trust will be distributed to the holders of such Certificates.
The ISDA Amount will be distributed to MSCS.
    
 
     The following definitions are used to determine the Applicable Premium:
 
     "Applicable Premium" means, with respect to a Note (or portion thereof)
being redeemed at any time, the excess of (A) the present value at such time of
the principal amount of such Note (or portion thereof) being redeemed plus all
interest payments due on such Note (or portion thereof) from and after the
redemption date, which present value shall be computed using a discount rate
equal to the Treasury Rate plus 50 basis points, over (B) the principal amount
of such Note (or portion thereof) being redeemed at such time. For purposes of
this definition, the present values of interest and principal payments will be
determined in accordance with generally accepted principles of financial
analysis.
 
     "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled and
published in the most recent Federal Reserve Statistical Release H.15(519) (the
"Statistical Release") which has become publicly available at least two Business
Days prior to the redemption date or, in the case of defeasance, prior to the
date of deposit (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the then
remaining average life to stated maturity of the Notes; provided, however, that
if the average life to stated maturity of the Notes is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall be obtained by linear interpolation
(calculated to the nearest one-twelfth of a year) from the weekly average yields
of United States Treasury securities for which such yields are given.
 
     No sinking fund is provided for the Notes.
 
FINAL DISTRIBUTION
 
   
     The Final Distribution on the Certificates, representing an amount equal to
the principal amount of and interest on the Notes, assuming the Notes had been
held until the Final Distribution Date, is expected to be made on the Final
Distribution Date. If the Yield on the Exercise Date is equal to or greater than
the reference U.S. Treasury Note yield of    % used to determine the interest
rate per annum borne by the Notes as set forth on the cover page of this
Prospectus, the Notes will mature on the Final Distribution Date. If the Yield
on the Exercise Date is less than such reference U.S. Treasury Note yield, the
maturity of the Notes will be extended and, prior to the Final Distribution
Date, one of the following will occur: (a) the interest rate borne by the Notes
will be reset and the Notes will be remarketed so as to yield net proceeds in
cash at least equal to the Remarketing Proceeds which, together with the amount
payable by the Company representing interest on the Notes through the Final
Distribution Date, will be sufficient to enable the Trustee to make the Final
Distribution on the Certificates, (b) the Company will exercise its option to
redeem the Notes on the Final Distribution Date at a purchase price equal to the
principal amount of and interest on the Notes plus the ISDA Amount or (c) the
Pass-Through Trust will exercise its Put Option and require the Company to
purchase the Notes on the Final Distribution Date at a purchase price equal to
the principal amount of and interest on the Notes. In any case, the principal of
and interest on the Notes will be distributed by the Pass-Through Trust to the
Certificateholders on the Final Distribution Date. The ISDA Amount (if any) will
be distributed to MSCS.
    
 
                                       27
<PAGE>   29
 
     Final Distribution upon a Successful Remarketing
 
   
     If the maturity of the Notes is extended, unless the Company exercises its
option to redeem the Notes (which the Company may exercise at any time
subsequent to the delivery of the Extension Notice and prior to the earlier of
the pricing of the remarketing and Remarketing Deadline), the interest rate
borne by the Notes will be reset in order that the Notes may be remarketed so as
to yield net proceeds in cash equal to the Remarketing Proceeds. On the Exercise
Date and once every 15 days thereafter, 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, and discount or premium at which
it believes it could remarket the Notes. The Company may then, on behalf of the
Pass-Through Trust, either request that Morgan Stanley & Co. Incorporated
remarket the Notes, select another investment banking institution to remarket
the Notes or exercise the option to redeem the Notes. Regardless of whether it
has been selected to act as remarketing agent, Morgan Stanley & Co. Incorporated
shall at all times be permitted to offer to purchase the Notes bearing a reset
interest rate specified by Morgan Stanley & Co. Incorporated for net proceeds at
least equal to the Remarketing Proceeds which offer the Company and the Trustee
shall be required to accept, unless (i) any other party shall have remarketed
the Notes bearing an interest rate less than or equal to that specified by
Morgan Stanley & Co. Incorporated and for net proceeds at least equal to the
Remarketing Proceeds or (ii) the Company exercises its option to redeem all of
the Notes on the Final Distribution Date at a purchase price equal to the
principal amount of and interest on the Notes plus the ISDA Amount. Upon the
closing of any remarketing, the portion of the proceeds representing principal
of the Notes, together with the amount paid by the Company representing interest
on the Notes through the Final Distribution Date, will be deposited with the
Trustee for distribution to Certificateholders, and the portion of the proceeds
representing the ISDA Amount will be distributed to MSCS.
    
 
     Final Distribution upon Optional Redemption of the Notes without Premium
 
   
     If the maturity of the Notes is extended, the Company may, in lieu of
permitting the Notes to be remarketed, exercise its option to redeem all of the
Notes on the Final Distribution Date at a purchase price equal to the principal
amount of and interest on the Notes plus the ISDA Amount, but without the
Applicable Premium. The Company may exercise this option at any time subsequent
to the delivery of the Extension Notice and prior to the earlier of the pricing
of the remarketing and Remarketing Deadline. The principal of and interest on
the Notes paid by the Company to the Pass-Through Trust will be distributed to
the Certificateholders on the Final Distribution Date. The ISDA Amount will be
distributed to MSCS.
    
 
     Final Distribution upon Exercise by the Trustee of Put Option
 
   
     If the maturity of the Notes is extended and for any reason the Trustee
does not receive an amount in cash equal to the principal amount of and interest
on the Notes by the Remarketing Deadline, the Pass-Through Trust will be deemed
to have exercised its Put Option and required the Company to purchase the Notes
on the Final Distribution Date at a purchase price equal to the principal amount
of and interest on the Notes. All payments in respect of the Notes paid by the
Company to the Pass-Through Trust upon exercise of the Put Option will be
distributed to Certificateholders on the Final Distribution Date.
    
 
CHANGE IN CONTROL
 
     In the event of any Change in Control, each Holder of a Note will have the
right, at such Holders option, subject to the terms and conditions of the Senior
Debt Indenture, to require the Company to repurchase all or any part of such
Holder's Note on the Change in Control Purchase Date after the mailing of
written notice by the Company of the occurrence of such Change in Control at a
repurchase price payable in cash equal to the Change in Control Purchase Price.
For details regarding notice and procedures and the definition of a Change in
Control, see "Description of Certificates -- Purchase of Certificates upon
Change in Control or Excess Proceeds Offer -- Change in Control."
 
                                       28
<PAGE>   30
 
   
     The Senior Debt Indenture requires the Company to 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
purchase Notes at the option of Holders upon a Change in Control. The Change in
Control purchase feature of the Notes may in certain circumstances make more
difficult or discourage a takeover of the Company and, thus, the removal of
incumbent management. The Change in Control purchase feature, however, is not
the result of management's knowledge of any specific effort to accumulate shares
of its common stock or to obtain control of the Company by means of a merger,
tender offer, solicitation or otherwise, or part of a plan by management to
adopt a series of antitakeover provisions. Instead, the Change in Control
purchase feature is a term contained in many similar debt offerings and the
terms of such feature result from negotiations between the Company and the
Underwriters. Management has no present intention to propose any antitakeover
measures although it is possible that the Company could decide to do so in the
future.
    
 
     No Note may be repurchased by the Company as a result of a Change of
Control if there has occurred and is continuing an Event of Default described
under "Description of the Trust Agreement -- Events of Default" (other than a
default in the payment of the Change in Control Purchase Price with respect to
the Notes). In addition, the Company's ability to purchase Notes may be limited
by its financial resources and its inability to raise the required funds because
of restrictions on issuance of securities contained in other contractual
arrangements.
 
CERTAIN COVENANTS
 
     The Senior Debt Indenture contains the covenants described below. Certain
capitalized terms used below are defined herein under the heading "Certain
Definitions."
 
     Limitation on Restricted Payments
 
     Under the terms of the Senior Debt Indenture, so long as any of the Notes
are Outstanding and until senior unsecured debt of the Company is rated BBB- or
above (or an equivalent rating) by Standard & Poor's and one Other Rating
Agency, at which time the Company will be permanently released from the
provisions of this "Limitation on Restricted Payments," the Company will not,
and will not permit any of its Restricted Subsidiaries, directly or indirectly,
to (i) declare or pay any dividend or make any distribution on the Capital Stock
of the Company to the direct or indirect holders of its Capital Stock (except
dividends or distributions payable solely in its Non-Convertible Capital Stock
or in options, warrants or other rights to purchase such Non-Convertible Capital
Stock and except dividends or distributions payable to the Company or a
Subsidiary), (ii) purchase, redeem or otherwise acquire or retire for value any
Capital Stock of the Company, or (iii) purchase, repurchase, redeem, defease or
otherwise acquire or retire for value, prior to scheduled maturity or scheduled
repayment thereof, any Subordinated Indebtedness (any such dividend,
distribution, purchase, redemption, repurchase, defeasing, other acquisition or
retirement being hereinafter referred to as a "Restricted Payment") if at the
time the Company or such Subsidiary makes such Restricted Payment: (1) an Event
of Default, or an event that with the lapse of time or the giving of notice or
both would constitute an Event of Default, shall have occurred and be continuing
(or would result therefrom); or (2) the aggregate amount of such Restricted
Payment and all other Restricted Payments made since May 6, 1997 would exceed
the sum of (a) $100,000,000 plus 100% of Consolidated Net Income from May 6,
1997 to the end of the most recent fiscal quarter ending at least 45 days prior
to the date of such Restricted Payment (or, in case such sum shall be a deficit,
minus 100% of the deficit) and (b) the aggregate Net Cash Proceeds received by
the Company from the issue or sale of or contribution with respect to its
Capital Stock after May 6, 1997.
 
     The foregoing provisions will not prohibit: (i) dividends or other
distributions paid in respect of any class of Capital Stock issued by the
Company in connection with the acquisition of any business or assets by the
Company or a Restricted Subsidiary where the dividends or other distributions
with respect to such Capital Stock are payable solely from the net earnings of
such business or assets; (ii) any purchase or redemption of Capital Stock of the
Company made by exchange for, or out of the proceeds of the substantially
concurrent sale of, Capital Stock of the Company (other than Redeemable Stock or
Exchangeable Stock); (iii) dividends
 
                                       29
<PAGE>   31
 
paid within 60 days after the date of declaration thereof if at such date of
declaration such dividends would have complied with this covenant; or (iv)
payments pursuant to the Tax Sharing Agreement.
 
     Limitation on Certain Liens
 
   
     Under the terms of the Senior Debt Indenture, so long as any of the Notes
are outstanding, the Company shall not create, incur, assume or suffer to exist
any Lien upon or with respect to any of its property of any character, including
without limitation any shares of Capital Stock of Consumers or Enterprises,
without making effective provision whereby the Notes shall be (so long as any
such other creditor shall be so secured) equally and ratably secured. The
foregoing restrictions shall not apply to (a) Liens securing Indebtedness of the
Company, provided that on the date such Liens are created, and after giving
effect to such Indebtedness, the aggregate principal amount at maturity of all
the secured Indebtedness of the Company at such date shall not exceed 5% of
Consolidated Net Tangible Assets or (b) certain liens for taxes, pledges to
secure workman's compensation, other statutory obligations and Support
Obligations, certain materialmen's, mechanic's and similar liens and certain
purchase money liens.
    
 
     Limitation on Asset Sales
 
   
     Under the terms of the Senior Debt Indenture, so long as any of the Notes
are outstanding, the Company may not sell, transfer or otherwise dispose of any
property or assets of the Company, including Capital Stock of any Consolidated
Subsidiary, in one transaction or a series of transactions in an amount which
exceeds $50,000,000 unless the Company shall (i) apply an amount equal to such
excess Net Cash Proceeds to permanently repay Indebtedness of a Consolidated
Subsidiary or Indebtedness of the Company which is pari passu with the Notes or
(ii) invest an equal amount not so used in clause (i) in property or assets of
related business within the Application Period or (iii) make an Excess Proceeds
Offer. The Company shall only be required to make an Excess Proceeds Offer to
purchase Notes from Holders pursuant to subsection (iii) if the Excess Proceeds
equal or exceed $25,000,000 at any given time.
    
 
   
     The procedures to be followed by the Company in making an Excess Proceeds
Offer, and for the acceptance of such offer by the Holders, shall be the same as
those set forth above in " Description of Certificates -- Purchase of
Certificates upon Change in Control or Excess Proceeds Offer" with respect to a
Change in Control.
    
 
     Limitation on Consolidation, Merger, Sale or Conveyance of Assets
 
   
     The Senior Debt Indenture provides that the Company may consolidate with or
merge into, or sell, lease or convey its property as an entirety or
substantially as an entirety to, any other corporation if such corporation
assumes the obligations of the Company under the Notes and the Senior Debt
Indenture and is organized and existing under the laws of the United States of
America, any state thereof or the District of Columbia.
    
 
   
     The Senior Debt Indenture further provides that so long as any of the Notes
are outstanding and until senior unsecured debt of the Company is rated BBB- or
above (or an equivalent rating) by Standard & Poor's and one Other Rating Agency
(at which time the Company will be permanently released from the following
restrictions), the Company shall not consolidate with or merge into any other
Person or sell, lease or convey the property of the Company in the entirety or
substantially as an entirety, unless (i) immediately after giving effect to such
transaction the Consolidated Net Worth of the surviving entity is at least equal
to the Consolidated Net Worth of the Company immediately prior to the
transaction, and (ii) after giving effect to such transaction, the surviving
entity would be entitled to incur at least one dollar of additional Indebtedness
(other than revolving Indebtedness to banks) pursuant to the first paragraph
under "--Limitation on Consolidated Indebtedness" below. Notwithstanding the
foregoing provisions, such a transaction may constitute a Change of Control as
described in "-- Purchase of Notes upon Change in Control" above and give rise
to the right of a Holder to direct the Trustee to require the Company to
repurchase all or part of such Holder's Notes.

                                       36
<PAGE>   38
 
     The Senior Debt Indenture also permits the Company and the Indenture
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Senior Debt Securities of all series then
outstanding and affected (voting as one class), to enter into supplemental
indentures, to add any provisions to, or change in any manner or eliminate any
of the provisions of, the Senior Debt Indenture or modify in any manner the
rights of the holders of the Senior Debt Securities of each such affected
series; provided, however, that the Company and the Indenture Trustee may not,
without the consent of the holder of each Senior Debt Security then outstanding
and affected thereby, enter into any supplemental indenture to: (a) change the
time of payment of the principal (or any installment of principal) of any Senior
Debt Security, or reduce the principal amount thereof, or reduce the rate or
change the time of payment of interest thereon, or impair the right to institute
suit for the enforcement of any payment on any Senior Debt Security when due; or
(b) reduce the percentage in principal amount of Senior Debt Securities of the
affected series, the consent of whose holders is required for any such
modification or for any waiver provided for in the Senior Debt Indenture;
provided further that no supplemental indenture referred to in the foregoing
clauses (a) and (b) which has a material adverse effect on MSCS may be entered

     Prior to the acceleration of the maturity of any Senior Debt Security, the
holders of a majority in aggregate principal amount of the Senior Debt
Securities of all series at the time outstanding with respect to which a default
or Event of Default has occurred and is continuing (voting as one class) may on
behalf of the holders of any all such affected Senior Debt Securities waive any
past default or Event of Default and its consequences, except a default or an
Event of Default (i) in the payment of the principal of or interest, if any, on
any Senior Debt Security, or (ii) in respect of a covenant or provision of the
Senior Debt Indenture which cannot be modified or amended without the consent of
the holder of each Senior Debt Security affected or MSCS, as the case may be.
    
 
DEFEASANCE, COVENANT DEFEASANCE AND DISCHARGE
 
   
     The Senior Debt Indenture provides that, at the option of the Company: (a)
the Company will be discharged from any and all obligations in respect of the
Notes (except for certain obligations to register the transfer of or exchange of
the Notes, to replace stolen, lost or mutilated Notes, to maintain paying
agencies and to maintain the trust described below), or (b) the Company need not
comply with certain restrictive covenants of the Senior Debt Indenture
(including those described under "Limitation on Consolidation, Merger, Sale or
Conveyance of Assets"), in each case if the Company (i) irrevocably deposits in
trust with the Trustee money, and/or securities backed by the full faith and
credit of the United States which, through the payment of the principal thereof
and interest thereon in accordance with their terms, will provide money in an
amount sufficient to pay all the principal of and Applicable Premium, if any,
and interest on the Notes on the Final Distribution Date and (ii) pays the ISDA
Amount, if any, to MSCS. To exercise such option, the Company is required, among
other things, to deliver to the Indenture Trustee an opinion of independent
counsel to the effect that the exercise of such option would not cause the
Holders of the Notes to recognize income, gain or loss for United States federal
income tax purposes as a result of such defeasance, and such Holders of Notes
will be subject to United States federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such defeasance
had not occurred, and, in the case of a discharge as described in clause (a) of
the preceding sentence, such opinion is to be accompanied by a private letter
ruling to the same effect received from the Internal Revenue Service, a revenue
ruling to such effect pertaining to a comparable form of transaction published
by the Internal Revenue Service or appropriate evidence that since the date of
the Senior Debt Indenture there has been a change in the applicable federal
income tax law.
    
 
     In the event the Company exercises its option to effect a covenant
defeasance with respect to the Notes as described in the preceding paragraph and
the Notes are thereafter declared due and payable because of the occurrence of
any Event of Default other than an Event of Default caused by failing to comply
with the covenants which are defeased, and the amount of money and securities on
deposit with the Indenture Trustee would be insufficient to pay amounts due on
the Notes at the time of the acceleration resulting from such Event of Default,
the Company would remain liable for such amounts.
 
                                       37

     The Company may also obtain a discharge of the Senior Debt Indenture with
respect to all Senior Debt Securities then outstanding by (a) irrevocably
depositing in trust with the Trustee money, and/or securities backed by the full
faith and credit of the United States which, through the payment of the
principal amount thereof and interest thereon in accordance with their terms,
will provide money in an amount sufficient to pay the principal amount of and
interest on the Senior Debt Securities on the stated maturities thereof
(including one or more redemption dates), provided that such Senior Debt
Securities are by their terms due and payable, within one year and (b) paying
the ISDA Amount, if any, as of the date of such deposit, to MSCS. See "Certain
Federal Income Tax Considerations -- Income of Holders -- Disposition or
Retirement of the Debt Instrument."
 
EVENTS OF DEFAULT
 
   
     The occurrence of any of the following events with respect to the Notes
will constitute an "Event of Default": (a) default for 30 days in the payment of
any interest on any of the Notes; (b) default in the payment when due of any of
the principal amount of or Applicable Premium, if any, on any of the Notes,
whether at maturity, upon redemption, acceleration, purchase by the Company at
the option of the Holders, of the Notes; (c) default in the payment when due of
the ISDA Amount, if any, whether on the Final Distribution Date, upon
redemption, acceleration or purchase by the Company, at the option of the
Holders or otherwise; (d) default for 60 days by the Company in the observance
or performance of any other covenant or agreement contained in the Senior Debt
Indenture after written notice thereof as provided in the Senior Debt Indenture;
(e) certain events of bankruptcy, insolvency or reorganization relating to the
Company or Consumers; (f) entry of final judgments against the Company or
Consumers aggregating in excess of $25,000,000 which remain undischarged or
unbonded for 60 days; or (g) a default resulting in the acceleration of
indebtedness of the Company or Consumers in excess of $25,000,000, which
acceleration has not been rescinded or annulled within 10 days after written
notice of such default as provided in the Senior Debt Indenture.
    
 
     If an Event of Default shall have occurred and be continuing, either the
Indenture Trustee or the Holders of not less than 25% in aggregate principal
amount of the Notes then outstanding may declare the principal amount of the
Notes and interest thereon to be due and payable immediately.
 
   
     Upon certain conditions, any such declaration may be rescinded and annulled
if all Events of Default, other than the nonpayment of accelerated principal,
with respect to the Senior Debt Securities of all such affected series then
outstanding shall have been cured or waived as provided in the Senior Debt
Indenture by the holders of a majority in aggregate principal amount of the
Senior Debt Securities of the affected series then outstanding.
    
 
     The Senior Debt Indenture provides that the Indenture Trustee will be under
no obligation to exercise any of its rights or powers under the Senior Debt
Indenture at the request, order or direction of the Holders of the Notes, unless
such Holders shall have offered to the Indenture Trustee reasonable indemnity.
Subject to such provisions for indemnity and certain other limitations contained
in the Senior Debt Indenture, the Holders of a majority in aggregate principal
amount of the Senior Debt Securities of each affected series then outstanding
(voting as one class) will have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Indenture Trustee,
or exercising any trust or power conferred on the Indenture Trustee, with
respect to the Senior Debt Securities of such affected series.
 
     The Senior Debt Indenture provides that no holder of Senior Debt
Securities, including any Holder of Notes, may institute any action against the
Company under the Senior Debt Indenture (except actions for payment of overdue
principal, Applicable Premium or interest) unless such holder previously shall
have given to the Indenture Trustee written notice of default and continuance
thereof and unless the holders of not less than 25% in aggregate principal
amount of Senior Debt Securities of each affected series then outstanding
(voting as one class) shall have requested the Indenture Trustee to institute
such action and shall have offered the Indenture Trustee reasonable indemnity,
the Indenture Trustee shall not have instituted such action within 60 days of
such request and the Indenture Trustee shall not have received direction
inconsistent with such
 
                                       38
<PAGE>   40
 
request by the Holders of a majority in aggregate principal amount of the Senior
Debt Securities of each affected series then outstanding (voting as one class).
 
     The Senior Debt Indenture requires the Company to furnish to the Indenture
Trustee annually a statement as to the Company's compliance with all conditions
and covenants under the Senior Debt Indenture. The Senior Debt Indenture
provides that the Indenture Trustee may withhold notice to the Holders of the
Notes of any default (except defaults as to payment of principal premium or
interest on the Notes) if it considers such withholding to be in the best
interests of the Holders thereof.
 
     Governing Law
 
     The Senior Debt Indenture will be governed by, and construed in accordance
with, the laws of the State of Michigan.
 
     Concerning the Indenture Trustee
 
     NBD Bank, the Indenture Trustee under the Senior Debt Indenture, is one of
a number of banks with which the Company and its subsidiaries maintain ordinary
banking relationships, including credit facilities.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     This summary is based on the Internal Revenue Code of 1986, as amended to
the date hereof, revenue rulings, judicial decisions and existing and proposed
Treasury regulations, including final regulations concerning the tax treatment
of debt instruments issued with original issue discount (the "OID Regulations"),
changes to any of which subsequent to the date of the Prospectus may affect the
tax consequences described herein.
 
     This summary discusses only Certificates held by Certificateholders as
capital assets within the meaning of Section 1221 of the Code. It does not
discuss all of the tax consequences that may be relevant to a Certificateholder
in light of its particular circumstances or to Certificateholders subject to
special rules, such as certain financial institutions, insurance companies,
dealers or Certificateholders holding the Certificates as part of a hedging
transaction or straddle. In all cases, prospective investors are advised to
consult their own tax advisors regarding the federal tax consequences to them of
holding, owning and disposing of Certificates, including the advisability of
making any of the elections described below, as well as any tax consequences
arising under the law of any other taxing jurisdiction. The Pass-Through Trust
will be provided with an opinion of Shearman & Sterling, special federal income
tax counsel to the Pass-Through Trust ("Federal Tax Counsel") regarding certain
federal income tax matters discussed below. An opinion of counsel, however, is
not binding on the IRS or the courts. The Pass-Through Trust has not sought, nor
does it intend to seek, a ruling from the IRS that its positions, as reflected
in the discussion below, will be accepted by the IRS. Moreover, there are no
cases or IRS rulings on similar transactions and, as a result, there can be no
assurance that the IRS will agree with the conclusions and discussion below.
 
     For purposes of this discussion "U.S. Person" means an individual who, for
federal income tax purposes, is a citizen or resident of the United States or a
corporation, partnership or other entity created or organized in or under the
laws of the United States, or any state thereof (other than a partnership that
is not treated as a United States Person under any applicable Treasury
regulations), an estate that is subject to U.S. federal income tax regardless of
the source of its income, or a trust if a court within the United States is able
to exercise primary supervision of the administration of the trust and one or
more U.S. Persons have the authority to control all substantial decisions of the
trust. Notwithstanding the preceding sentence, to the extent provided in
Treasury regulations, certain trusts in existence on August 20, 1996, and
treated as U.S. Persons prior to such date, that elect to continue to be treated
as U.S. Persons, also will be a U.S. Person. "U.S. Owner" means a
Certificateholder that is a U.S. Person and "Non-U.S. Owner" means a
Certificateholder that is not a U.S. Person.

CLASSIFICATION OF INVESTMENT ARRANGEMENT
 
     The Pass-Through Trust will be classified as a grantor trust and not as an
association (or publicly traded partnership) taxable as a corporation for
federal income tax purposes.
 
INCOME OF HOLDERS
 
     In General
 
   
     For U.S. federal income tax purposes, while the characterization of the
transaction is not without doubt, Federal Tax Counsel believes that the
Certificates represent ownership of a debt instrument issued by the Company
through the Pass-Through Trust (the "Debt Instrument"). The Debt Instrument will
have an absolute maturity corresponding to the Final Distribution Date, but will
otherwise have the characteristics of the Notes, including the principal amount
of and interest rate payable on the Notes. The Debt Instrument will not contain
any of the rights associated with the ISDA Master Agreement because the
Certificateholders will have no interest in the ISDA Master Agreement. The
Certificateholders will agree by their purchase of the Certificates to treat the
Certificates as described in this paragraph.
    
 
     U.S. Owners
 
     Each U.S. Owner will be required to report on its federal income tax return
its pro rata share of the income from the Debt Instrument, including interest
income at the interest rate on the Debt Instrument, in accordance with its
method of accounting.
 
     Original Issue Discount. The initial Certificateholders will purchase the
Debt Instrument at a discount below its principal amount. As provided in the
Code and the OID Regulations, the excess of the "stated redemption price" of the
Debt Instrument (i.e., its principal amount) over its "issue price" (defined as
the initial offering price to the public, excluding bond houses and brokers, at
which a substantial amount of the offering is sold) will be original issue
discount if such excess equals or exceeds a de minimis amount (i.e., one-quarter
of one percent of such Debt Instrument's stated redemption price multiplied by
the number of complete years to its maturity). A Debt Instrument having more
than a de minimis amount of original issue discount is referred to herein as an
"OID Debt Instrument." A U.S. Owner of a Debt Instrument with a de minimis
amount of original issue discount will include any de minimis original issue
discount in income, as capital gain, when the principal payment is made on the
Debt Instrument.
 
     U.S. Owners are required to include original issue discount in income as it
accrues, which may be before the receipt of the cash attributable to such
income, based on a compounding of interest at a constant rate (using the
original yield to maturity of the Debt Instrument). Under these rules, U.S.
Owners generally must include in income increasingly greater amounts of original
issue discount in successive accrual periods. The OID Regulations permit U.S.
Owners to use accrual periods of any length up to one year (including daily
accrual periods) to compute accruals of original issue discount, provided each
scheduled payment of principal or interest occurs either on the first or the
last day of an accrual period.
 
     Acquisition Premium and Market Discount. In the event that a U.S. Owner
purchases an OID Debt Instrument at an acquisition premium (i.e., at a price in
excess of its "adjusted issue price" but less than its stated redemption price),
the amount includible in income in each taxable year as original issue discount
is reduced by that portion of the excess properly allocable to such year. The
adjusted issue price is defined as the sum of the issue price of the Debt
Instrument and the aggregate amount of previously accrued original issue
discount, less any prior payments of amounts included in its stated redemption
price. Acquisition premium is allocated on a pro rata basis to each accrual of
original issue discount, so that the U.S. Owner is allowed to reduce each
accrual of original issue discount by a constant fraction.
 
     A U.S. Owner that purchases at a "market discount" (i.e., at a price less
than the stated redemption price or, in the case of an OID Debt Instrument, the
adjusted issue price) will be required (unless such difference is less than a de
minimis amount) to treat any principal payments on, or any gain realized upon
the disposition or retirement of, the Debt Instrument as interest income to the
extent of the market discount that accrued while such U.S. Owner held such Debt
Instrument, unless the U.S. Owner elects to include such market discount in
 
                                       40
<PAGE>   42
 
income on a current basis. Market discount is considered to be de minimis if it
is less than one-quarter of one percent of such Debt Instrument's stated
redemption price multiplied by the number of complete years to maturity after
the U.S. Owner acquired the Certificate. If the Debt Instrument has more than a
de minimis amount of market discount and is disposed of in a nontaxable
transaction (other than a nonrecognition transaction described in Section
1276(d) of the Code), accrued market discount will be includible as ordinary
income to the U.S. Owner as if such U.S. Owner had sold the Debt Instrument at
its then fair market value. A U.S. Owner that acquired at a market discount and
that does not elect to include market discount in income on a current basis also
may be required to defer the deduction for a portion of the interest expense on
any indebtedness incurred or continued to purchase or carry the Debt Instrument
until the deferred income is realized.
 
     Premium. A U.S. Owner that purchases for an amount in excess of the
principal amount will be treated as having premium with respect to the Debt
Instrument in the amount of such excess. A U.S. Owner that purchases an OID Debt
Instrument at a premium is not required to include in income any original issue
discount with respect to such Debt Instrument. If a U.S. Owner makes an election
under Section 171 of the Code to treat such premium as "amortizable bond
premium," the amount of interest that must be included in such U.S. Owner's
income for such accrual period will be reduced by the portion of the premium
allocable to such period based on the Debt Instrument's yield to maturity. The
U.S. Owner may not assume that the call will be exercised and must amortize
premium to the maturity date. If the Debt Instrument is in fact called, any
unamortized premium may be deducted in the year of the call. If a U.S. Owner
makes the election under Section 171, the election also shall apply to all bonds
the interest on which is not excludible from gross income ("Fully Taxable
Bonds") held by the U.S. Owner at the beginning of the first taxable year to
which the election applies and to all such Fully Taxable Bonds thereafter
acquired by it, and is irrevocable without the consent of the IRS. If such an
election is not made, such a U.S. Owner must include the full amount of each
interest payment in income in accordance with its regular method of accounting
and will receive a tax benefit from the premium only in computing its gain or
loss upon the sale or other disposition or retirement of the Debt Instrument.
 
     Accrual Method Election. Under the OID Regulations, a U.S. Owner is
permitted to elect to include in gross income its entire return on the Debt
Instrument (i.e., the excess of all remaining payments to be received on the
Debt Instrument over the amount paid for the Debt Instrument by such U.S. Owner)
based on the compounding of interest at a constant rate. Such an election for a
Debt Instrument with amortizable bond premium (or market discount) will result
in a deemed election for all of the U.S. Owner's debt instruments with
amortizable bond premium (or market discount) and may be revoked only with
permission of the IRS.
 
     Disposition or Retirement of the Debt Instrument. Upon the sale, exchange
or other disposition of the Debt Instrument, or upon the retirement of the Debt
Instrument, a U.S. Owner will recognize gain or loss equal to the difference, if
any, between the amount realized upon the disposition or retirement (including
any call premium) and the U.S. Owner's tax basis in the Debt Instrument. A U.S.
Owner's tax basis for determining gain or loss on the disposition or retirement
of the Debt Instrument will be the cost of the Debt Instrument to such U.S.
Owner, increased by the amount of original issue discount and any market
discount includible in such U.S. Owner's gross income with respect to the Debt
Instrument, and decreased by the amount of any payments under the Debt
Instrument that are part of its stated redemption price and by the portion of
any premium applied to reduce interest payments as described above.
 
     Gain or loss upon the disposition or retirement of the Debt Instrument will
be capital gain or loss, except to the extent the gain represents accrued stated
interest, original issue discount or market discount on the Debt Instrument not
previously included in gross income, to which extent such gain or loss would be
treated as ordinary income. Any capital gain or loss will be long-term capital
gain or loss if at the time of disposition or retirement the Debt Instrument has
been held for more than one year.
 
     Depending on the circumstances, it is possible that a modification of the
terms of the Debt Instrument, including a substitution of other assets for the
Debt Instrument following a default on the Debt Instrument, would be a taxable
event to Certificateholders on which they would recognize gain or loss.
Moreover, a
 
                                       41
<PAGE>   43
 
defeasance or discharge of the Company's obligation as a result of a deposit of
money or securities with the Indenture Trustee would be treated as an exchange
of the Debt Instrument for other property. Accordingly, Certificateholders may
be required to recognize gain or loss for federal income tax purposes upon such
exchange. In addition, such Certificateholders thereafter may be required to
recognize income from such property which could be different from the amount
that would be includible in the absence of such deposit.
 
     Alternative Characterizations. Although Federal Tax Counsel believes that
such treatment would be inappropriate, under one possible characterization, the
Company would be treated as issuing a contingent payment debt instrument to the
Pass-Through Trust with the following terms: (i) a principal amount equal to the
principal amount of the Notes, (ii) noncontingent interest payments at the rate
of interest payable on the Notes and a contingent interest payment in an amount
equal to the amount due under the ISDA Master Agreement and (iii) an absolute
maturity corresponding to the Final Distribution Date. Under this
characterization, the Certificateholders would be treated as owning the
noncontingent portion of such debt instrument, which portion would be treated as
a "stripped" debt instrument under Section 1286 of the Code. The
Certificateholders would not be taxed on the contingent portion of the debt
instrument corresponding to the amount due under the ISDA Master Agreement,
which would be owned by and taxed to MSCS. In the case of an initial
Certificateholder, characterization of the Certificates as ownership of a
stripped debt instrument generally would not alter the tax consequences set
forth above. A subsequent Certificateholder would be treated under this
characterization as purchasing a newly-issued debt instrument, rather than as
purchasing an existing debt instrument. Consequently, any discount that would be
treated as market discount with respect to an existing debt instrument for a
subsequent Certificateholder would instead be treated as original issue
discount. As described under "Original Issue Discount" and "Acquisition Premium
and Market Discount" above, a Certificateholder must accrue original issue
discount currently, whereas market discount is accrued currently only at the
election of the Certificateholder. There may also be other differences in the
tax treatment of Certificates to a subsequent Certificateholder under this
characterization.
 
     Under another alternative characterization, although contrary to the form
of the transaction, the Company could be treated as issuing a contingent payment
debt instrument maturing on           , 2012, to the Pass-Through Trust, in
which case the Certificateholders would be treated as owning such debt
instrument and as having written a call option on such debt instrument to MSCS.
Pursuant to the call option, MSCS would be considered to have the right to
purchase the contingent payment debt instrument from the Pass-Through Trust at
100% of its principal amount on the Final Distribution Date. The contingent
payment debt instrument under this characterization would be treated as having a
principal amount equal to the principal amount of the Notes and as bearing
interest at the rate of interest payable on the Notes from the issue date
through the Final Distribution Date and at a different fixed rate of interest,
determined based on circumstances as of the Final Distribution Date, from the
Final Distribution Date through           , 2012. The debt instrument also would
be treated as containing a put option that provides the Pass-Through Trust with
the right to require the Company to retire the debt instrument at 100% of its
principal amount on the Final Distribution Date. The Trustee would be deemed to
exercise the put option if MSCS does not exercise the call option. Under this
characterization, each Certificateholder would be required to allocate its
purchase price between, and separately account for, the call option and the
contingent payment debt instrument. In this regard, the income from the debt
instrument would be determined in accordance with a projected payment schedule
determined under certain Treasury regulations governing contingent payment debt
instruments. Federal Tax Counsel does not believe the characterization described
in this paragraph is an appropriate characterization of the transaction,
however, and therefore will not provide the Certificateholders with a projected
payment schedule.
 
     Investors should consult their tax advisors regarding the alternative
characterizations set forth above.
 
     Non-U.S. Owners
 
     Interest. Interest (including original issue discount) on a Debt Instrument
of a Non-U.S. Owner will be subject to a 30 percent federal income and
withholding tax, unless an exemption is established. Under such certification
requirements, the Certificateholder must certify, under penalties of perjury,
that it is not a "United States person" and is the beneficial owner of the
Certificates, and must provide its name and address.
 
                                       42
<PAGE>   44
 
     Disposition or Retirement of the Debt Instrument. A Non-U.S. Owner that
does not have certain present or former connections with the United States
(e.g., holding such Non-U.S. Owner's Debt Instrument in connection with the
conduct of a trade or business within the United States or being present in the
United States for 183 days or more during a taxable year) generally will not be
subject to federal income tax, and no withholding of such tax will be required,
with respect to any gain realized upon the disposition or retirement of the Debt
Instrument.
 
     Backup Withholding
 
     Payments made on the Debt Instrument and proceeds from the sale of the Debt
Instrument will not be subject to a "backup" withholding tax of 31 percent
unless, in general, the Certificateholder fails to comply with certain reporting
procedures and is not an exempt recipient under applicable provisions of the
Code.
 
     New Withholding Regulations
 
     The Treasury Department has issued new regulations which make certain
modifications to the withholding, backup withholding and information reporting
rules. The new regulations generally are effective for payments made after
December 31, 1998. Investors should consult their tax advisors regarding such
regulations.
 
     THE FEDERAL TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A CERTIFICATEHOLDER'S
PARTICULAR SITUATION. CERTIFICATEHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS
WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF
THE CERTIFICATES, INCLUDING THE TAX CONSEQUENCES UNDER THE TAX LAWS OF THE
UNITED STATES, STATES, LOCALITIES, COUNTRIES OTHER THAN THE UNITED STATES AND
ANY OTHER TAXING JURISDICTIONS AND THE POSSIBLE EFFECTS OF CHANGES IN SUCH TAX
LAWS.
 
                       STATE AND LOCAL TAX CONSIDERATIONS
 
     In addition to the federal income tax consequences described in "Certain
Federal Income Tax Considerations," potential investors should consider the
state and local income tax consequences of the acquisition, ownership and
disposition of the Certificates. State and local income tax law may differ
substantially from the corresponding federal law, and this discussion does not
purport to describe any aspect of the income tax laws of any state or locality.
Therefore, potential investors should consult their own tax advisors with
respect to the various state and local tax consequences of an investment in the
Certificates.
 
                              ERISA CONSIDERATIONS
 
     The Employee Retirement Income Security Act of 1974, as amended, and the
Code, impose certain restrictions on (a) employee benefit plans (as defined in
Section 3(3) of ERISA) that are subject to Title I of ERISA, (b) plans described
in Section 4975(e)(1) of the Code that are subject to Section 4975 of the Code,
including individual retirement accounts or Keogh plans, (c) any entities whose
underlying assets include "plan assets" under the Plan Asset Regulation (as
defined below) (each a "Plan") and (d) persons who have certain specified
relationships to such Plans ("Parties-in-Interest" under ERISA and "Disqualified
Persons" under the Code). Moreover, based on the reasoning of the United States
Supreme Court in John Hancock Life Ins. Co. v. Harris Trust and Sav. Bank, 114
S. Ct. 517 (1993), an insurance company's general account may be deemed to
include assets of the Plans investing in the general account (e.g.,through the
purchase of an annuity contract). ERISA also imposes certain duties on persons
who are fiduciaries of Plans subject to ERISA, and ERISA and Section 4975 of the
Code prohibit certain transactions between a Plan and Parties-in-Interest or
Disqualified Persons with respect to such Plan.
 
     The Department of Labor has issued a regulation (29 C.F.R. Section
2510.3-101) concerning the definition of what constitutes the assets of a Plan
(the "Plan Asset Regulation"). The Plan Asset Regulation
 
                                       43
<PAGE>   45
 
provides that, as a general rule, the underlying assets and properties of
corporations, partnerships, trusts and certain other entities in which a Plan
purchases an "equity interest" will be deemed for purposes of ERISA and Section
4975 of the Code to be assets of the investing Plan unless certain exceptions
apply. It is likely that the Certificates offered hereby would be treated as
"equity interests" for purposes of the Plan Asset Regulation. In addition, there
can be no assurance that any of the exceptions set forth in the Plan Asset
Regulation will apply to the purchase of the Certificates.
 
     Under the terms of the Plan Asset Regulation, if the Pass-Through Trust
were deemed to hold Plan assets by reason of a Plan's investment in a
Certificate, such Plan assets would include an undivided interest in the Notes
and any other assets of the Trust that relate to such Certificate. In such
event, the persons providing services, or exercising any discretionary authority
or control, with respect to such assets may be subject to the fiduciary
responsibility provisions of Title I of ERISA and the prohibited transaction
provisions of ERISA and Section 4975 of the Code with respect to transactions
involving such assets. In order to avoid certain prohibited transactions that
might otherwise arise in connection with the Pass-Through trust assets, each
investing Plan, by its purchase of Certificates, will be deemed to have directed
the Trustee to purchase the Notes and to have approved all of the documents
relating to the Notes. Moreover, the Certificateholders will have the right to
direct the Trustee as to the exercise of remedies in connection with any Event
of Default.
 
     In addition, the Company, the Trustee and the Underwriter, because of their
activities or the activities of their respective affiliates, may be considered
to be Parties-in-Interest or Disqualified Persons with respect to certain Plans.
If the Certificates are acquired by a Plan with respect to which the Company,
the Trustee or the Underwriter is a Party-in-Interest or Disqualified Person,
such transaction could be deemed to be a direct or indirect violation of the
prohibited transaction rules of ERISA and Section 4975 of the Code unless such
transaction were subject to one or more statutory or administrative exemptions
such as Prohibited Transaction Class Exemption ("PTCE") 90-1, which exempts
certain transactions involving insurance company pooled separate accounts; PTCE
91-38, which exempts certain transactions involving bank collective investment
funds; PTCE 84-14, which exempts certain transactions effected on behalf of a
Plan by a "qualified professional asset manager"; PTCE 95-60, which exempts
certain transactions involving insurance company general accounts; or PTCE
96-23, which exempts certain transactions effected on behalf of Plan by an "in-
house asset manager." Even if the conditions specified in one or more of these
exemptions are met, the scope of relief provided may not necessarily cover all
acts that might be construed as prohibited transactions.
 
     Accordingly, each purchaser of Certificates will, by its purchase, be
deemed to have represented and warranted that either (i) no part of the assets
to be used by it to purchase and hold such Certificates constitutes the assets
of any Plan, or (ii) one or more prohibited transaction statutory or
administrative exemptions applies such that the use of such Plan assets to
purchase and hold such Certificates will not constitute a non-exempt prohibited
transaction within the meaning of Section 406 of ERISA or Section 4975 of the
Code. See "Transfer Restrictions."
 
     It should also be noted that the Small Business Job Protection Act of 1996
added new Section 401(c) of ERISA relating to the status of the assets of
insurance company general accounts under ERISA and Section 4975 of the Code.
Pursuant to Section 401(c), the Department of Labor is required to issue final
regulations (the "General Account Regulations") not later than December 31, 1997
with respect to insurance policies issued on or before December 31, 1998 that
are supported by an insurer's general account. The General Account Regulations
are to provide guidance on which assets held by the insurer constitute "plan
assets" for purposes of the fiduciary responsibility provisions of ERISA and
Section 4975 of the Code. Section 401(c) also provides that, except in the case
of avoidance of the General Account Regulation and actions brought by the
Secretary of Labor relating to certain breaches of fiduciary duties that also
constitute breaches of state or federal criminal law, until the date that is 18
months after the General Account Regulations become final, no liability under
the fiduciary responsibility and prohibited transaction provisions of ERISA and
Section 4975 of the Code may result on the basis of a claim that the assets of
the general account of an insurance company constitute the assets of any such
Plan. The Plan asset status of insurance company separate accounts is unaffected
by new Section 401(c) of ERISA, and separate account assets continue to
generally be treated as the assets of any such Plan invested in such separate
account.

     Prior to making an investment in the Certificates, prospective Plan
investors should consult with their legal advisers concerning the impact of
ERISA and the Code and the potential consequences of such investment with
respect to their specific circumstances. Moreover, each Plan fiduciary should
take into account, among other considerations, whether the fiduciary has the
authority to make the investment; whether the investment would constitute a
direct or indirect transaction with a Party-in-Interest or Disqualified Person;
and whether under the general fiduciary standards of investment prudence and
diversification, an investment in the Certificates is appropriate for the Plan,
taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio.

     The Underwriters will earn a commission of $       , which constitutes
     % of the principal amount of the Certificates.
    
 
   
     The Underwriting Agreement provides that the obligation of the Underwriter
to pay for and accept delivery of the Certificates is subject to approval of
certain legal matters by their counsel and to certain other conditions. The
Underwriters are obligated to take and pay for all of the Certificates if any
are taken.
    
 
   
     The Underwriting Agreement provides that the Company and the Underwriters
will indemnify each other against certain liabilities, including liabilities
under the Securities Act, and will contribute to payments the other may be
required to make in respect thereof. Subject to certain conditions, the Company
has also agreed to indemnify the Trustee against certain civil liabilities.
    
 
   
     The Underwriters have advised the Pass-Through Trust and the Company that
they intend to offer part of the Certificates at the offering price set forth on
the cover page of this Prospectus directly to Qualified Institutional Buyers and
to Accredited Institutional Investors and part to certain dealers at prices that
represent concessions not to exceed   % of the principal amount of the
Certificates. The Underwriters may allow, and such dealers may reallow,
concessions not to exceed   % of the principal amount of the Certificates to
certain other dealers. After the initial offering of the Certificates, the
offering price and other selling terms may from time to time be varied by the
Underwriters.
    
 
   
     In order to facilitate the offering of the Certificates, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Certificates. Specifically, the Underwriters may overallot in
connection with the Offering, creating a short position in the Certificates for
their own account. In addition, to cover overallotments or to stabilize the
price of the Certificates, the Underwriters may bid for, and purchase, the
Certificates in the open market. Finally, the Underwriters may reclaim selling
concessions allowed to an agent or a dealer for distributing the Certificates in
the Offering if the Underwriters repurchase previously distributed Certificates
in transactions to cover the short positions, in stabilization transactions or
otherwise. Any of these activities may stabilize or maintain the market price of
the Certificates above independent market levels. The Underwriters are not
required to engage in these activities, and may end any of these activities at
any time.
    
 
   
     Each of Morgan Stanley & Co. Incorporated, Donaldson, Lufkin & Jenrette

                             TRANSFER RESTRICTIONS
 
     In order to qualify for the exemption from the Investment Company Act of
1940, as amended, afforded by Rule 3a-7 of the Commission thereunder, the
Certificates are being offered and sold, and may be resold, in minimum
denominations of $250,000 only (i) to "qualified institutional buyers" (as
defined in Rule 144A under the Securities Act) and (ii) to a limited number of
other institutional "accredited investors" (as defined in Rule 501(a)(1), (2),
(3) or (7) under the Securities Act) ("Institutional Accredited Investors"). In
addition, as a further measure to ensure that resales will be made subject to
such limitations, the Company and the Trustee have sent an "important notice" to
DTC for retransmission to each of its participants, to the effect that sales and
resales of Certificates may only be made to Qualified Institutional Buyers and
Institutional Accredited Investors.
 
     Accordingly, by its purchase of Certificates, each purchaser of
Certificates will be deemed to:
 
          1. represent that it is purchasing the Certificates for its own
     account or an account with respect to which it exercises sole investment
     discretion and that it and any such account is (i) a Qualified
     Institutional Buyer or (ii) an Institutional Accredited Investor;
 
          2. agree that, if it should resell or otherwise transfer any of the
     Certificates, it will do so only (i) to the Company, (ii) to a Qualified
     Institutional Buyer or (iii) to an Institutional Accredited Investor;
 
          3. agree that it will deliver to each person to whom it transfers
     Certificates notice of the restrictions on transfer of such Certificates;
 
          4. understand that the Certificates will bear a legend to the
     following effect unless otherwise agreed by the Company and the Holder
     hereof:
 
          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;
 
          5. agree that if it should resell or otherwise transfer any of the
     Certificates, it will do so only in minimum denominations of $250,000; and
 
          6. represent that either (i) no part of the assets to be used by it to
     purchase and hold the Certificates constitutes the assets of any Plan or
     (ii) one or more prohibited transaction statutory or administrative
     exemptions applies such that the use of such Plan assets to purchase and
     hold such Certificates will not constitute a non-exempt prohibited
     transaction within the meaning of Section 406 of ERISA or Section 4975 of
     the Code.
 
                                 LEGAL MATTERS
 
   
     Certain legal matters with respect to the Certificates and the Notes will
be passed upon for CMS Energy by Michael D. VanHemert, Assistant General Counsel
for CMS Energy. Certain other legal matters will be passed upon by Shearman &
Sterling and by Reid & Priest LLP, both of which are acting as counsel for the
Underwriters. Certain matters of Delaware law relating to the validity of the
Certificates offered hereby will be passed upon for the Pass-Through Trust by
Richards, Layton & Finger, special Delaware counsel to the Pass-Through Trust.
Michael D. VanHemert and Shearman & Sterling will rely on the opinion of
Richards, Layton

& Finger as to matters relating to the validity of the Certificates under the
Trust Agreement. Reid & Priest LLP provides legal services to an affiliate of
CMS Energy and has, from time to time, provided legal services to CMS Energy.
 
                                    EXPERTS
 
     The consolidated financial statements and schedules of CMS Energy as of
December 31, 1996 and 1995, and for each of the three years in the period ended
December 31, 1996 incorporated by reference in this Prospectus, have been
audited by Arthur Andersen LLP (formerly Arthur Andersen & Co.), independent
public accountants, as indicated in their reports with respect thereto, and are
included herein in reliance upon the authority of said firm as experts in
accounting and auditing in giving said reports.
 
   
     With respect to the unaudited interim consolidated financial information
for the periods ended March 31, June 30, and September 30, 1996 and 1997, Arthur
Andersen LLP has applied limited procedures in accordance with professional
standards for a review of such information. However, their separate reports
thereon state that they did not audit and they did not express an opinion on
that interim consolidated financial information. Accordingly, the degree of
reliance on their reports on that information should be restricted in light of
the limited nature of the review procedures applied. In addition, the
accountants are not subject to the liability provisions of Section 11 of the
Securities Act of 1933, as amended ("Securities Act"), for their reports on the
unaudited interim consolidated financial information because these reports are
not "reports" or "part" of the registration statement prepared or certified by
the accountants within the meaning of Sections 7 and 11 of the Securities Act.
    
 
     Future consolidated financial statements of CMS Energy and the reports
thereon of Arthur Andersen LLP also will be incorporated by reference in this
Prospectus in reliance upon the authority of that firm as experts in giving
those reports to the extent that said firm has audited said consolidated
financial statements and consented to the use of their reports thereon.
 
                             AVAILABLE INFORMATION
 
     The Pass-Through Trust has not been, and it is expected that it will not
be, required to file reports with the Commission or to deliver an annual report
to Certificateholders pursuant to the Exchange Act.
 
     The Company is subject to the informational requirements of the Exchange
Act and, in accordance therewith, files reports, proxy statements and other
information with the Commission. Reports, proxy statements and other information
filed by the Company with the Commission pursuant to the informational
requirements of the Exchange Act may be inspected and copied at the public
reference facilities maintained by the Commission at 450 Fifth Street, N.W.,
Room 1024, Washington, D.C. 20549, and at the Commission's regional offices

Citicorp Center, 500 West Madison Street (Suite 1400), Chicago, Illinois 60661;
and copies of such material may be obtained from the Public Reference Section of
the Commission, Washington, D.C. 20549, at prescribed rates, or through the

stock are listed on the New York Stock Exchange, and reports, proxy statements
and other information concerning CMS Energy may also be inspected and copied at

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The following resolution was adopted by the Board of Directors of CMS
Energy on May 6, 1987:
 
     RESOLVED: That effective March 1, 1987 the Corporation shall indemnify to
the full extent permitted by law every person (including the estate, heirs and
legal representatives of such person in the event of the decease, incompetency,
insolvency or bankruptcy of such person) who is or was a director, officer,
partner, trustee, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, partner, trustee,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against all liability, costs, expenses, including attorneys'
fees, judgments, penalties, fines and amounts paid in settlement, incurred by or
imposed upon the person in connection with or resulting from any claim or any
threatened, pending or completed action, suit or proceeding whether civil,
criminal, administrative, investigative or of whatever nature, arising from the
person's service or capacity as, or by reason of the fact that the person is or
was, a director, officer, partner, trustee, employee or agent of the Corporation
or is or was serving at the request of the Corporation as a director, officer,
partner, trustee, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise. Such right of indemnification shall not be
deemed exclusive of any other rights to which the person may be entitled under
statute, bylaw, agreement, vote of shareholders or otherwise.
 
CMS Energy's Bylaws provide:
 
     The Corporation may purchase and maintain liability insurance, to the full
extent permitted by law, on behalf of any person who is or was a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against any
liability asserted against such person and incurred by such person in any such
capacity.
 
Article VIII of the Articles of Incorporation reads:
 
     A director shall not be personally liable to the Corporation or its
shareholders for monetary damages for breach of duty as a director except (i)
for a breach of the director's duty of loyalty to the Corporation or its
shareholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for a violation of
Section 551(l) of the Michigan Business Corporation Act, and (iv) any action
from which the director derived an improper personal benefit. No amendment to or
repeal of this Article VIII, and no modification to its provisions by law, shall
apply to, or have any effect upon, the liability or alleged liability of any
director of the Corporation for or with respect to any acts or omissions of such
director occurring prior to such amendment, repeal or modification.
 
                                      II-1
<PAGE>   52
 
Article IX of the Articles of Incorporation reads:
 
     Each director and each officer of the Corporation shall be indemnified by
the Corporation to the fullest extent permitted by law against expenses
(including attorneys' fees), judgments, penalties, fines and amounts paid in
settlement actually and reasonably incurred by him or her in connection with the
defense of any proceeding in which he or she was or is a party or is threatened
to be made a party by reason of being or having been a director or an officer of
the Corporation. Such right of indemnification is not exclusive of any other
rights to which such director or officer may be entitled under any now or
thereafter existing statute, any other provision of these Articles, bylaw,
agreement, vote of shareholders or otherwise. If the Business Corporation Act of
the State of Michigan is amended after approval by the shareholders of this
Article IX to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the Business Corporation Act of the State of Michigan, as so amended. Any repeal
or modification of this Article IX by the shareholders of the Corporation shall
not adversely affect any right or protection of a director of the Corporation
existing at the time of such repeal or modification.
 
     Sections 561 through 571 of the Michigan Business Corporation Act provides
CMS Energy with the power to indemnify directors, officers, employees and agents
against certain expenses and payments, and to purchase and maintain insurance on
behalf of directors, officers, employees and agents.
 
     Officers and directors are covered within specified monetary limits by
insurance against certain losses arising from claims made by reason of their
being directors or officers of CMS Energy or of CMS Energy's subsidiaries and
CMS Energy's officers and directors are indemnified against such losses by
reason of their being or having been directors of officers or another
corporation, partnership, joint venture, trust or other enterprise at CMS
Energy's request. In addition, CMS Energy has indemnified each of its present
directors by contracts that contain affirmative provisions essentially similar
to those in sections 561 through 571 of the Michigan Business Corporation Act
cited above.
 
     The Trust Agreement of the Trust provides that to the fullest extent
permitted by applicable law, the Company shall indemnify and hold harmless the
Trustee from and against any loss, damage, claim, liability, penalty or
reasonable expense incurred without negligence, bad faith or wilful misconduct
on its part, arising out of or in connection with the acceptance or
administration of the Trust Agreement, including the reasonable costs and legal
fees of defending itself against any claim or liability in connection with the
exercise or performance of any of its powers or duties under the Trust
Agreement, except any such cost or expense as may be attributable to the
Trustee's negligence, bad faith or wilful misconduct.

ITEM 17. UNDERTAKINGS.
 
     The undersigned registrants hereby undertake:
 
     (1) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to section
13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in this registration statement shall be deemed to be a
new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (2) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that as
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
be governed by the final adjudication of such issue.
 
     (3) That (i) for purposes of determining any liability under the Securities
Act of 1933, the information omitted from the form of prospectus filed as part
of this Registration Statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective; and (ii) for the purpose of
determining any liability under the Securities Act of 1933, each post-effective
amendment that contains a form of prospectus shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

Capitalized terms used but not defined herein have the meanings assigned to
them in the Trust Agreement or the Senior Debt Indenture.

   
   The Company and the Pass-Through Trust have prepared and filed with the
Securities and Exchange Commission (the "Commission"), in accordance with the
provisions of the Securities Act of 1933, as amended (the "Securities Act"), a
combined registration statement on Form S-3 and S-1 (Registration Nos. 
333-41395 and 333-41395-01) relating to the Certificates and the Notes.  The
registration statement as amended at the time it became effective, including
the information (if any) deemed to be part of the registration statement at the
time of effectiveness pursuant to Rule 430A under the Securities Act, is
hereinafter referred to as the "Registration Statement"; the prospectus in the
form first used to confirm sales of Certificates (including the documents
incorporated by reference therein) is hereinafter referred to as the
"Prospectus."  If the Company and the Pass-Through Trust have filed an
abbreviated registration statement to register additional Certificates and
Notes pursuant to Rule 462(b) under the Securities Act (the "Rule 462
Registration Statement"), then any reference herein to the term "Registration
Statement" shall be deemed to include such Rule 462 Registration Statement. 
The Prospectus and the Registration Statement incorporate certain reports of
the Company filed pursuant to Section 13 or 14 or 15 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act").  Any reference herein to the
terms "amend," "amendment" or "supplement" with respect to the Registration
Statement or the Prospectus shall be deemed to include only amendments or
supplements to the Registration Statement or Prospectus, as the case may be,
and documents incorporated by reference therein after the date of this
Agreement and prior to the termination of the offering of the Certificates by
the Underwriters.
    

   
   1.  Purchase and Sale:  Upon the basis of the representations and warranties
and on the terms and subject to the conditions herein set forth, the Company
agrees to cause the Pass-Through Trust to sell to the respective Underwriters,
severally and not jointly, and the respective Underwriters, severally and not
jointly, agree to purchase from the Pass-Through Trust, at the purchase price
specified in Schedule III hereto, the respective principal amounts of
Certificates set opposite their names in Schedule II hereto.
    
        
   The Company is advised by the Representatives that the Underwriters propose
to make a public offering of their respective portions of the Certificates as
soon as practicable, in their judgment, after this Agreement has become
effective.  The Company is further advised by the Representatives that the
Certificates are to be offered to the public initially at ____% of the
principal amount of the Certificates and to certain dealers selected by you at
a price that represents a concession not in excess of ____% of the principal
amount of the Certificates, and that any Underwriter may allow, and such
dealers may reallow, a concession not in excess of ____% of the principal
amount of the Certificates to certain other dealers.

   As compensation to the Underwriters for their commitments and obligations 
hereunder in respect of the Certificates, including their undertakings 
to distribute certificates, the Company will pay to the Underwriters 
an amount equal to that percentage of the aggregate principal amount 
of the Certificates purchased by the Underwriters as set forth in Schedule 
III.  Such payment will be made simultaneously with the payment by you 
to the Trustee of the purchase price of the Certificates as specified in
Sections 1 and 2 hereof.  Payment of such compensation shall be made by wire
transfer of Federal or other immediately available funds.

   The Company hereby agrees that, without the prior written consent of Morgan
Stanley & Co. Incorporated, the Company will not offer, sell, contract to sell
or otherwise issue debt securities substantially similar to the Notes for a
period from the date of the execution of this Agreement to the day of the Time
of Purchase (as hereinafter defined).

   2.  Payment and Delivery:  The Company will cause the Pass-Through Trust to
issue and deliver against payment of the purchase price the Certificates to be
purchased by each Underwriter hereunder and to be offered and sold by the
Underwriters in the form of one or more permanent global securities in
definitive form without interest coupons (the "Global





<PAGE>   3

                                       3

Certificates") deposited with the Trustee as custodian for The Depository Trust
Company ("DTC") and registered in the name of Cede & Co., as nominee for DTC.
Each Global Certificate shall include the legend regarding restrictions on
transfer set forth under "Transfer Restrictions" in the Prospectus.  Interests
in any permanent Global Certificates will be held only in book-entry form
through DTC, except in the limited circumstances described in the Prospectus.

   The Company agrees to make the Certificates available for inspection by the
Underwriters at the offices of Morgan Stanley & Co. Incorporated at least 24
hours prior to the Time of Purchase (as hereinafter defined), in definitive,
fully registered form.

   

   Payment for the Certificates issued by the Pass-Through Trust shall be made
to Pass-Through Trust in Federal or other immediately available funds in New
York City (or such other place or places of payment as shall be agreed upon by
the Company, the Pass Through Trust and the Representatives in writing), upon
the delivery to the Trustee as custodian for DTC of the Global Certificate
representing all of the Certificates (or such other place or places of delivery
as shall be agreed upon by the Company, the Pass-Through Trust and the
Representatives).  Such payment and delivery shall be made at 10:00 A.M., New
York time on            , 1998 (or on such later business day as shall be
agreed upon by the Company, the Pass-Through Trust and the Representatives in
writing), unless postponed in accordance with the provisions of Section 10
hereof.  The day and time at which payment and delivery for the Certificates
are to be made is herein called the "Time of Purchase."

  pending or, to the knowledge of the Company, threatened against the Company
  or any Subsidiary by any governmental

  authority that (i) questions the validity, enforceability or performance of
  the Notes, the Senior Debt Indenture, the Trust Agreement or this Agreement
  or (ii) if determined adversely, is likely to have a material adverse effect
  on the business or financial condition of the Company and the Subsidiaries,
  taken as a whole, or materially adversely affect the ability of the Company
  to perform its obligations hereunder or the consummation of the transactions
  contemplated by this Agreement.

   (o)   There has not been any material and adverse change in the business,
  properties or financial condition of the Company and its Subsidiaries, taken
  as a whole, from that set forth in the Registration Statement (other than
  changes referred to in or contemplated by the Registration Statement or the
  Prospectus).

   (p)   Except as set forth in the Prospectus, no event or condition exists
  that constitutes, or with the giving of notice or lapse of time or both would
  constitute, a default or any breach or failure to perform by the Company or
  any of its Significant Subsidiaries in any material respect under any
  indenture, mortgage, loan agreement, lease or other material agreement or
  instrument to which the Company or any of its Significant Subsidiaries is a
  party or by which it or any of its Significant Subsidiaries, or any of their
  respective properties, may be bound.

   (q)   Neither the Pass-Through Trust nor the Company is an "investment
  company" or an entity "controlled" by an "investment company," as such terms
  are defined in the Investment Company Act of 1940, as amended.

   7.  Representation and Warranties of Underwriters:  Each Underwriter,
severally and not jointly, warrants and represents that:

   (d)   It will only sell Certificates in minimum denominations of $250,000.

   8.  Indemnification:





<PAGE>   13

                                       13

  (a)  The Company agrees, to the extent permitted by law, to indemnify and
hold harmless each of the Underwriters and each person, if any, who controls
any such Underwriter within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Securities Act or otherwise, and to reimburse the Underwriters and
such controlling person or persons, if any, for any legal or other expenses
incurred by them in connection with defending any action, suit or proceeding
(including governmental investigations) as provided in Section 8(c) hereof,
insofar as such losses, claims, damages, liabilities or actions, suits or
proceedings (including governmental investigations) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement, any preliminary prospectus as of its
issue date (if used prior to the date of the Prospectus), or, if the Prospectus
shall be amended or supplemented, in the Prospectus as so amended or
supplemented (if such Prospectus or such Prospectus as amended or supplemented
is used after the period of time referred to in Section 5(e) hereof, it shall
contain or be used with such amendments or supplements as the Company deems
necessary to comply with Section 10(a) of the Securities Act), or arise out of
or are based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
actions arise out of or are based upon any such untrue statement or alleged
untrue statement or omission or alleged omission which was made in such
preliminary prospectus, Prospectus or Registration Statement, or in the
Prospectus as so amended or supplemented, in reliance upon and in conformity
with information furnished in writing to the Company by, or through the
Representatives on behalf of, any Underwriter expressly for use therein or with
any statements in or omissions from that part of the Registration Statement
that shall constitute the Statement of Eligibility and Qualification under the
Trust Indenture Act of the Indenture Trustee under the Indenture, and except
that this indemnity shall not inure to the benefit of any Underwriter (or any
person controlling such Underwriter) on account of any losses, claims, damages,
liabilities or actions, suits or proceedings arising from the sale of the
Certificates to any person if a copy of the Prospectus, as the same may then be
supplemented or amended (excluding, however, any document then incorporated or
deemed incorporated therein by reference), was not sent or given by or on
behalf of such Underwriter to such person (i) with or prior to the written
confirmation of sale involved or (ii) as soon as available after such written
confirmation, relating to an event occurring prior to the payment for and
delivery to such person of the Certificates involved in such sale, and the
omission or alleged omission or untrue statement or alleged untrue statement
was corrected in the Prospectus as supplemented or amended at such time.

   The Company's indemnity agreement contained in this Section 8(a), and the
covenants, representations and warranties of the Company contained in this
Agreement, shall remain in full force and effect regardless of any
investigation made by or on behalf of any person, and shall survive the
delivery of and payment for the Certificates hereunder, and the indemnity
agreement contained in this Section 8 shall survive any termination of this
Agreement.





<PAGE>   14

                                       14

The liabilities of the Company in this Section 8(a) are in addition to any
other liabilities of the Company under this Agreement or otherwise.

  (b)  Each Underwriter agrees, severally and not jointly, to the extent
permitted by law, to indemnify, hold harmless and reimburse the Company, its
directors and such of its officers as shall have signed the Registration
Statement, each other Underwriter and each person, if any, who controls the
Company or any such other Underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, to the same extent and upon
the same terms as the indemnity agreement of the Company set forth in Section
8(a) hereof, but only with respect to alleged untrue statements or omissions
made in the Registration Statement or in the Prospectus, as amended or
supplemented, (if applicable) in reliance upon and in conformity with
information furnished in writing to the Company by such Underwriter expressly
for use therein.

   The indemnity agreement on the part of each Underwriter contained in this
Section 8(b) and the representations and warranties of such Underwriter
contained in this Agreement shall remain in full force and effect regardless of
any investigation made by or on behalf of the Company or any other person, and
shall survive the delivery of and payment for the Certificates hereunder, and
the indemnity agreement contained in this Section 8(b) shall survive any
termination of this Agreement.  The liabilities of each Underwriter in Section
8(b) are in addition to any other liabilities of such Underwriter under this
Agreement or otherwise.

  (c)  If a claim is made or an action, suit or proceeding (including
governmental investigations) is commenced or threatened against any person as
to which indemnity may be sought under Section 8(a) or 8(b), such person (the
"Indemnified Person") shall notify the person against whom such indemnity may
be sought (the "Indemnifying Person") promptly after any assertion of such
claim threatening to institute an action, suit or proceeding or if such an
action, suit or proceeding is commenced against such Indemnified Person,
promptly after such Indemnified Person shall have been served with a summons or
other first legal process, giving information as to the nature and basis of the
claim.  Failure to so notify the Indemnifying Person shall not, however,
relieve the Indemnifying Person from any liability which it may have on account
of the indemnity under Section 8(a) or 8(b) if the Indemnifying Person has not
been prejudiced in any material respect by such failure.  Subject to the
immediately succeeding sentence, the Indemnifying Person shall assume the
defense of any such litigation or proceeding, including the employment of
counsel and the payment of all expenses, with such counsel being designated,
subject to the immediately succeeding sentence, in writing by the
Representatives in the case of parties indemnified pursuant to Section 8(b) and
by the Company in the case of parties indemnified pursuant to Section 8(a).
Any Indemnified Person shall have the right to participate in such litigation
or proceeding and to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to
the retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include (x) the Indemnifying Person and (y)
the Indemnified Person and, in the written opinion





<PAGE>   15

                                       15

of counsel to such Indemnified Person, representation of both parties by the
same counsel would be inappropriate due to actual or likely conflicts of
interest between them, in either of which cases the reasonable fees and
expenses of counsel (including disbursements) for such Indemnified Person shall
be reimbursed by the Indemnifying Person to the Indemnified Person.  If there
is a conflict as described in clause (ii) above, and the Indemnified Persons
have participated in the litigation or proceeding utilizing separate counsel
whose fees and expenses have been reimbursed by the Indemnifying Person and the
Indemnified Persons, or any of them, are found to be solely liable, such
Indemnified Persons shall repay to the Indemnifying Person such fees and
expenses of such separate counsel as the Indemnifying Person shall have
reimbursed.  It is understood that the Indemnifying Person shall not, in
connection with any litigation or proceeding or related litigation or
proceedings in the same jurisdiction as to which the Indemnified Persons are
entitled to such separate representation, be liable under this Agreement for
the reasonable fees and out-of-pocket expenses of more than one separate firm
(together with not more than one appropriate local counsel) for all such
Indemnified Persons.  Subject to the next paragraph, all such fees and expenses
shall be reimbursed by payment to the Indemnified Persons of such reasonable
fees and expenses of counsel promptly after payment thereof by the Indemnified
Persons.

   In furtherance of the requirement above that fees and expenses of any
separate counsel for the Indemnified Persons shall be reasonable, the
Representatives and the Company agree that the Indemnifying Person's
obligations to pay such fees and expenses shall be conditioned upon the
following:

   (1)   in case separate counsel is proposed to be retained by the Indemnified
  Persons pursuant to clause (ii) of the preceding paragraph, the Indemnified
  Persons shall in good faith fully consult with the Indemnifying Person in
  advance as to the selection of such counsel;

   (2)   reimbursable fees and expenses of such separate counsel shall be
  detailed and supported in a manner reasonably acceptable to the Indemnifying
  Person (but nothing herein shall be deemed to require the furnishing to the
  Indemnifying Person of any information, including without limitation,
  computer print-outs of lawyers' daily time entries, to the extent that, in
  the judgment of such counsel, furnishing such information might reasonably be
  expected to result in a waiver of any attorney-client privilege); and

   (3)   the Company and the Representatives shall cooperate in monitoring and
  controlling the fees and expenses of separate counsel for Indemnified Persons
  for which the Indemnifying Person is liable hereunder, and the Indemnified
  Person shall use every reasonable effort to cause such separate counsel to
  minimize the duplication of activities as between themselves and counsel to
  the Indemnifying Person.





<PAGE>   16

                                       16

   The Indemnifying Person shall not be liable for any settlement of any
litigation or proceeding effected without the written consent of the
Indemnifying Person, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees, subject to the
provisions of this Section 8, to indemnify the Indemnified Person from and
against any loss, damage, liability or expenses by reason of such settlement or
judgment.  The Indemnifying Person shall not, without the prior written consent
of the Indemnified Persons, effect any settlement of any pending or threatened
litigation, proceeding or claim in respect of which indemnity has been properly
sought by the Indemnified Persons hereunder, unless such settlement includes an
unconditional release by the claimant of all Indemnified Persons from all
liability with respect to claims which are the subject matter of such
litigation, proceeding or claim.

         9.      Contribution:  If the indemnification provided for in Section
8 above is unavailable to or insufficient to hold harmless an Indemnified
Person under such Section in respect of any losses, claims, damages or
liabilities (or actions, suits or proceedings (including governmental
investigations) in respect thereof) referred to therein, then each Indemnifying
Person under Section 8 shall contribute to the amount paid or payable by such
Indemnified Person as a result of such losses, claims, damages or liabilities
(or actions in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Indemnifying Person on the one hand and
the Indemnified Person on the other from the offering of the Certificates.  If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law, then each Indemnifying Person shall contribute to
such amount paid or payable by such Indemnified Person in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of each Indemnifying Person, if any, on the one hand and the Indemnified
Person on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions, suits or
proceedings (including governmental investigations) in respect thereof), as
well as any other relevant equitable considerations.  The relative benefits
received by the Company on the one hand and the Underwriters on the other shall
be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company and the total
underwriting discounts and commission received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus, bear to the
aggregate offering price of the Certificates.  The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company on the one
hand or the Underwriters on the other and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.  The Company and the Underwriters agree that it would
not be just and equitable if contribution pursuant to this Section 9 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
9.  The amount paid or payable by an Indemnified Person as a result of the
losses, claims, damages or liabilities (or actions, suits or





<PAGE>   17

                                       17

proceedings (including governmental proceedings) in respect thereof) referred
to above in this Section 9 shall be deemed to include any legal or other
expenses reasonably incurred by such Indemnified Person in connection with
investigating or defending any such action, suits or proceedings (including
governmental proceedings) or claim, provided that the provisions of Section 8
have been complied with (in all material respects) in respect of any separate
counsel for such Indemnified Person.  Notwithstanding the provisions of this
Section 9, no Underwriter shall be required to contribute any amount greater
than the excess of (i) the total price at which the Certificates underwritten
by it and distributed to investors were offered to investors over (ii) the
amount of any damages which such Underwriter has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  The
Underwriters' obligations in this Section 9 to contribute are several in
proportion to their respective underwriting obligations and not joint.

                 The agreement with respect to contribution contained in
Section 9 hereof shall remain in full force and effect regardless of any
investigation made by or on behalf of the Company or any Underwriter, and shall
survive delivery of and payment for the Certificates hereunder and any
termination of this Agreement.

         10.     Substitution of Underwriters:  If any Underwriter under this
Agreement shall fail or refuse (otherwise than for some reason sufficient to
justify in accordance with the terms hereof, the termination of its obligations
hereunder) to purchase the Certificates which it had agreed to purchase on the
Time of Purchase, the Representatives shall immediately notify the Company and
the Representatives and the other Underwriters may, within 36 hours of the
giving of such notice, determine to purchase, or to procure one or more other
members of the National Association of Securities Dealers, Inc. ("NASD") (or,
if not members of the NASD, who are foreign banks, dealers or institutions not
registered under the Exchange Act and who agree in making sales to comply with
the NASD's Rules of Fair Practice), satisfactory to the Company, to purchase,
upon the terms herein set forth, the principal amount of Certificates which the
defaulting Underwriter had agreed to purchase.  If any non-defaulting
Underwriter or Underwriters shall determine to exercise such right, the
Representatives shall give written notice to the Company of such determination
within 36 hours after the Company shall have received notice of any such
default, and thereupon the Time of Purchase shall be postponed for such period,
not exceeding three business days, as the Company shall determine.  If in the
event of such a default, the Representatives shall fail to give such notice, or
shall within such 36-hour period give written notice to the Company that no
other Underwriter or Underwriters, or others, will exercise such right, then
this Agreement may be terminated by the Company, upon like notice given to the
Representatives within a further period of 36 hours.  If in such case the
Company shall not elect to terminate this Agreement, it shall have the right,
irrespective of such default:





<PAGE>   18

                                       18

                 (a)      to require such non-defaulting Underwriters to
         purchase and pay for the respective principal amounts of Certificates
         which they had severally agreed to purchase hereunder, as hereinabove
         provided, and, in addition, the principal amount of Certificates which
         the defaulting Underwriter shall have so failed to purchase up to a
         principal amount thereof equal to one-ninth (1/9) of the respective
         principal amounts of Certificates which such non-defaulting
         Underwriters have otherwise agreed to purchase hereunder; and/or

                 (b)      to procure one or more other members of the NASD (or,
         if not members of the NASD, who are foreign banks, dealers or
         institutions not registered under the Exchange Act and who agree in
         making sales to comply with the NASD's Rules of Fair Practice), to
         purchase, upon the terms herein set forth, the principal amount of
         Certificates which such defaulting Underwriter had agreed to purchase,
         or that portion thereof which the remaining Underwriters shall not be
         obligated to purchase pursuant to the foregoing clause (a).

                 In the event the Company shall exercise its rights under
clause (a) and/or (b) above, the Company shall give written notice thereof to
the Representatives within such further period of 36 hours, and thereupon the
Time of Purchase shall be postponed for such period, not exceeding five
business days, as the Company shall determine.  In the event the Company shall
be entitled to but shall not elect to exercise its rights under clause (a)
and/or (b), the Company shall be deemed to have elected to terminate this
Agreement.

                 Any action taken by the Company under this Section 10 shall
not relieve any defaulting Underwriter from liability in respect of any default
of such Underwriter under this Agreement.  Termination by the Company under
this Section 10 shall be without any liability on the part of the Company or
any non-defaulting Underwriter.

                 In the computation of any period of 36 hours referred to in
this Section 9, there shall be excluded a period of 24 hours in respect of each
Saturday, Sunday or legal holiday which would otherwise be included in such
period of time.

         11.     Termination of Agreement:  This Agreement may be terminated at
any time prior to the Time of Purchase by the Representatives, if, prior to
such time (i) trading generally in securities on the New York Stock Exchange
shall have been suspended by the Commission or the New York Stock Exchange,
(ii) trading of any securities of the Company shall have been suspended on any
exchange or over-the-counter market, (iii) a general moratorium on commercial
banking activities in New York shall have been declared by federal or New York
State authorities or (iv) there shall have occurred any outbreak or material
escalation of hostilities or any material adverse disruption in financial
markets or any other calamity or crisis, the effect of which on the financial
markets of the United States is such as to impair, in the





<PAGE>   19

                                       19

Representatives' reasonable judgment, after having made due inquiry, the
marketability of the Certificates.

                 If the Representatives elect to terminate this Agreement, as
provided in this Section 11, the Representatives will promptly notify the
Company and each other Underwriter by telephone or telecopy, confirmed by
letter.  If this Agreement shall not be carried out by any Underwriter for any
reason permitted hereunder, or if the sale of the Certificates to the
Underwriters as herein contemplated shall not be carried out because the
Company is not able to comply with the terms hereof, the Company shall not be
under any obligation under this Agreement and shall not be liable to any
Underwriter or to any member of any selling group for the loss of anticipated
profits from the transactions contemplated by this Agreement and the
Underwriters shall be under no liability to the Company nor be under any
liability under this Agreement to one another.

                 Notwithstanding the foregoing, the provisions of Sections
5(g), 5(i), 8 and 9 shall survive any termination of this Agreement.

         12.     Notices:  All notices hereunder shall, unless otherwise
expressly provided, be in writing and be delivered at or mailed to the
following addresses or be sent by telecopy as follows:  if to the Underwriters
or the Representatives, to the Representatives at the address or number, as

Energy Corporation, Attention:  Senior Vice President - Finance, Fairlane Plaza
South, Suite 1100, 330 Town Center Drive, Dearborn, Michigan 48126 (Telecopy:
313-436-9548).

         13.     Parties in Interest:  The Agreement herein set forth has been
and is made solely for the benefit of the Underwriters, the Company (including
the directors thereof and such of the officers thereof as shall have signed the
Registration Statement), and the controlling persons, if any, referred to in
Section 8 hereof, and their respective successors, assigns, executors and
administrators, and, except as expressly otherwise provided in Section 10
hereof, no other person shall acquire or have any right under or by virtue of
this Agreement.

         14.     Definition of Certain Terms:  The term "Underwriters," as used
herein, shall be deemed to mean the several persons, firms or corporations,
named in Schedule II hereto (including the Representatives herein mentioned, if
so named), and the term "Representatives," as used herein, shall be deemed to
mean the representative or representatives designated by, or in the manner
authorized by, the Underwriters in Schedule I hereto.  All obligations of the
Underwriters hereunder are several and not joint.  If there shall be only one
person, firm or corporation named in Schedule I and Schedule II hereto, the
term "Underwriters" and the term "Representatives," as used herein, shall mean
such person, firm or corporation.  If the firm or firms listed in Schedule I
hereto are the same as the firm or firms listed in Schedule II hereto, then the

deemed to refer to such firm or firms.  The term "successors" as used in this
Agreement shall not include

any purchaser, as such purchaser, of any of the Certificates from any of the
respective Underwriters.

         15.     Governing Law:  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York.

         16.     Counterparts:  This Agreement may be executed by any one or

purposes of this definition, the present values of interest and principal 
payments will be determined in accordance with generally accepted principles 
of financial analysis.

              "Treasury Rate" means the yield to maturity at the time of
computation of United States Treasury securities with a constant maturity (as
compiled and published in the most recent Federal Reserve Statistical Release
H.15(519) (the "Statistical Release") which has become publicly available at
least two Business Days prior to the redemption date or, in the case of
defeasance, prior to the date of deposit (or, if such Statistical Release is no
longer published, any publicly available source of similar market data)) most
nearly equal to the then remaining average life to stated maturity of the
X-TRAS; provided, however, that if the average life to stated maturity of the
X-TRAS is not equal to the constant maturity of a United States Treasury
security for which a weekly average yield is given, the Treasury Rate shall be
obtained by linear interpolation (calculated to the nearest one-twelfth of a
year) from the weekly average yields of United States Treasury securities for
which such yields are given.

              In the event of redemption of the X-TRAS in part, new X-TRAS for
the unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation hereof.

   
              If the X-TRAS are extended until the Extended Stated Maturity,
the Issuer shall have the option (the "FD Redemption Option"), in lieu of
permitting the X-TRAS to be remarketed in accordance with Section 8.01 of the
Indenture, to redeem the X-TRAS in whole on the Initial Stated Maturity

                                     32

   
, by irrevocable notice given to the Indenture Trustee, the Pass Through
Trustee, the Extension Option Buyer and the Calculation Agent not later than
the Remarketing Deadline, at a redemption price, payable in cash, equal to the
sum of (i) 100% of the  principal amount of the X-TRAS being redeemed together
with accrued interest, if any, thereon to the Initial Stated Maturity plus (ii)
the ISDA Amount, if any, as of the Exercise Date (as calculated by the 
Calculation Agent and notified to the Issuer, the Indenture Trustee and the 
Pass Through Trustee within five Business Days thereafter), which redemption 
price shall be payable at the Initial Stated Maturity.  The Notional Amount 
used to determine the ISDA Amount shall be the aggregate principal amount of 
the X-TRAS outstanding as of the Exercise Date.
    

              If a Change in Control occurs, the Issuer shall notify the Holder
of this Security, the Indenture Trustee, the Pass Through Trustee and the
Extension Option Buyer of such occurrence and each Holder shall have the right
to require the Issuer to make a Required Repurchase of all or any part of this
Security at a Change in Control Purchase Price equal ( ) 101% of the
principal amount of the X-TRAS to be so purchased together with accrued
interest thereon to the date of repurchase plus, (in the aggregate with all
other X-TRAS repurchased pursuant to such Required Repurchase) the ISDA Amount,
if any, as of such date of repurchase as determined by the Extension Option
Buyer and notified to the Issuer, the Indenture Trustee and the Pass Through
Trustee by 10 a.m., New York City time, on such date, as more fully provided in
the Indenture and subject to the terms and conditions set forth therein.  

<PAGE>   33
                                     33

In the event of a Required Repurchase of only a portion of this
Security, a new Security or Notes for the unrepurchased portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

   
              In the event that the Issuer has Excess Proceeds from an Asset
Sale, it shall be required to make an offer to purchase from Holders on a pro
rata basis an aggregate principal amount of X-TRAS equal to the Excess
Proceeds, at a purchase price equal to the sum of (i) 100% of the principal
amount of and unpaid interest, if any, to the purchase date on such X-TRAS,
plus (ii) (in the aggregate with all other X-TRAS repurchased pursuant to such
Excess Proceeds Offer) the ISDA Amount as determined by the Extension Option
Buyer and notified to the Issuer, the Indenture Trustee and the Pass Through
Trustee by 10 a.m., New York City time, on such date of repurchase. The
procedures to be followed by the Issuer in making such an offer, and for 
acceptance of such offer by Holders, shall be the same as those set forth
in the Indenture with respect to a Change in Control.
    

   
              If the maturity of the X-TRAS is extended and for any reason the
Pass Through Trustee does not receive an amount in cash equal to the principal
amount of and interest on the X-TRAS plus the ISDA Amount by the Remarketing
Deadline, the Holders of the X-TRAS will be deemed to have exercised the Put
Option and required the Issuer to purchase all of the outstanding X-TRAS on the
Initial Stated Maturity at a purchase price equal to 100% of the principal 
amount of and interest on the X-TRAS.

                                     34

              If an Event of Default with respect to this Security shall occur
and be continuing, the principal of this Security may be declared due and
payable in the manner and with the effect provided in the Indenture.  If any
such acceleration occurs, the Issuer will also be obligated to pay the
ISDA Amount, if any, as of the date of such acceleration, as determined by
the Extension Option Buyer and notified to the Issuer, the Indenture Trustee
and the Pass Through Trustee within [five] Business Days after the date of such
acceleration.

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

              The Indenture contains provisions for defeasance at any time of
(i) the entire indebtedness of this Security or (ii) certain restrictive 
covenants and Events of Default with respect to this Security, in each case 
upon compliance with certain conditions set forth therein.

              The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Holders of all Outstanding
X-TRAS under the Indenture at any time by the Issuer and the 

<PAGE>   35
                                     35

Indenture Trustee with the consent of the Holders of not less than a
majority in principal amount of Securities of all series then Outstanding and
affected (voting as one class).  No such amendment or modification may be made
to the Indenture which has a material adverse effect on the Extension Option
Buyer without the consent of the Extension Option Buyer.

              The Indenture permits the Holders of not less than a majority in
principal amount of Securities of all series at the time Outstanding with
respect to which a default shall have occurred and be continuing (voting as one
class) to waive on behalf of the Holders of all Outstanding Securities of such
series any past default by the Issuer, provided that no such waiver may be made
with respect to a default in the payment of the principal of or the interest on
any Security of such series or the default by the Issuer in respect of certain
covenants or provisions of the Indenture, the modification or amendment of
which must be consented to by the Holder of each Outstanding Security of each
series affected or by the Extension Option Buyer, as the case may be.

              As set forth in, and subject to, the provisions of the Indenture,
no Holder of any Securities of any series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Indenture Trustee written notice
of a continuing Event of Default, the Holders of not less than 25% in principal
amount of the Outstanding Securities of each affected series (voting as one
class) shall have made written request, and offered reasonable indemnity, to
the Indenture Trustee to institute such proceeding as trustee, and the
Indenture Trustee shall not have received from the Holders of a majority in
principal amount of the Outstanding Securities of each affected 

<PAGE>   36

                                     36

   
series (voting as one class) a direction inconsistent with such request
and shall have failed to institute such proceeding within 60 days; provided,
however, that such limitations do not apply to a suit instituted by the Holder
hereof for the enforcement of payment of the principal of (and premium, if any)
or any interest on this Security on or after the respective due dates expressed
herein.
    

              No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Issuer, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.

              As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registerable in the
Security Register, upon surrender of this Security for registration of transfer
at the office or agency of the Issuer in any place where the principal of and
any premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Issuer and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

              The X-TRAS are issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof.  As provided in
the Indenture and subject to certain limitations therein set forth, X-TRAS are
exchangeable for a like aggregate 

<PAGE>   37

                                     37

principal amount of X-TRAS and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

              No service charge shall be made for any such registration of
transfer or exchange, but the Issuer may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

              The Issuer shall not be required to (a) issue, exchange or
register the transfer of this Security for a period of 15 days next preceding
the mailing of the notice of redemption of X-TRAS or (b) exchange or register
the transfer of any Security or any portion thereof selected, called or being
called for redemption, except in the case of any Security to be redeemed in
part, the portion thereof not so to be redeemed.

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

              All terms used in this Security without definition which are 
defined in the Indenture shall have the meanings assigned to them in the 
Indenture.

              SECTION 2.05.  Form of Indenture Trustee's Certificate of
Authentication.  The Indenture Trustee's certificates of authentication shall
be in substantially the following form:

                                     38

              This is one of the Securities of the series designated herein
referred to in the within-mentioned Indenture.

                               CHANGE IN CONTROL

              SECTION 3.01.  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 Holder of X-TRAS shall have the right to
require that the Issuer repurchase (a "Required Repurchase") all or any part of
such Holder's X-TRAS at a repurchase price  payable in cash equal to
101% of the principal amount of such X-TRAS plus 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 X-TRAS repurchased pursuant to 
this Section 3.01) the ISDA Amount, if any, as of the Change in Control 
Purchase Date as determined by the Extension Option Buyer and notified to the 
Issuer, the Indenture Trustee and the Pass Through Trustee by 10 a.m., 
New York City time, on such date. The Notional Amount used to determine the  
Extension Amount shall be equal to the aggregate principal amount of X-TRAS 
tendered for repurchase and not withdrawn.

                                     39

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

                     (i)    that a Change in Control has occurred and that such
              Holder has the right to require the Issuer to repurchase all or
              any part of such Holder's X-TRAS at the Change in Control
              Purchase Price;

                     (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 Holders must follow to cause
              the X-TRAS to be repurchased, which shall be consistent with this
              Section and the Indenture.  

              (b)    Holders electing to have X-TRAS repurchased must deliver 
       a written notice (the "Change in Control Purchase Notice") to the
       Paying Agent (initially the Indenture Trustee) at its corporate trust 
       office in Detroit, Michigan, or any other office of the 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 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 Issuer 
       pursuant to the change in control provisions of the Indenture; 

<PAGE>   40

                                     40


       and (iii) unless the X-TRAS are represented by one or more Global
       Notes, the certificate numbers of the X-TRAS to be delivered by the
       Holder thereof for repurchase by the Issuer.  Any Change in Control
       Purchase Notice may be withdrawn by the Holder 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 and, if applicable, the
       certificate numbers of the X-TRAS as to which the withdrawal notice
       relates and the principal amount of such X-TRAS, if any, which remains
       subject to a Change in Control Purchase Notice.

           (c)    Payment of the Change in Control Purchase Price for X-TRAS for
       which a Change in Control Purchase Notice has been delivered and not
       withdrawn is conditioned upon delivery of such X-TRAS (together with
       necessary endorsements) to the Paying Agent at its office in Detroit,
       Michigan, or any other office of the 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 Notice.  Payment of the Change in Control Purchase Price for
       such X-TRAS will be made promptly following the later of the Change in
       Control Purchase Date or the time of delivery of such X-TRAS.  If the
       Paying Agent holds, in accordance with the terms of the Indenture, money
       sufficient to pay the Change in Control Purchase Price 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, and all other rights
       of the Holder shall 

<PAGE>   41
                                     41

       terminate (other than the right to receive the Change in Control
       Purchase Price upon delivery of the X-TRAS).

              (d)    The Issuer 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 Issuer to
       repurchase X-TRAS at the option of Holders upon a Change in Control.

              (e)    No X-TRAS may be repurchased by the Issuer 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).

                                   ARTICLE IV

                       ADDITIONAL COVENANTS OF THE ISSUER
                           WITH RESPECT TO THE X-TRAS

   

              SECTION 4.01.  Limitation on Certain Liens.  So long as any of the
X-TRAS are outstanding, the Issuer shall not create, incur, assume or suffer to
exist any Lien or any other type of arrangement intended or having the effect
of conferring upon a creditor of the Issuer or any Subsidiary a preferential
interest upon or with respect to any of its property of any character,
including without limitation any shares of Capital Stock of Consumers or
Enterprises, without making effective provision whereby the X-TRAS shall (so
long as any such other 
    

<PAGE>   42

                                     42


creditor shall be so secured) be equally and ratably secured (along
with any other creditor similarly entitled to be secured) by a direct Lien on
all property subject to such Lien, provided, however, that the foregoing
restrictions shall not apply to:
        
              (i)    Liens for taxes, assessments or governmental charges or
          levies to the extent not past due; 

              (ii)   pledges or deposits to secure (a) obligations under 
          workmen's compensation laws or similar legislation, (b) statutory 
          obligations of the Issuer or (c) Support Obligations at any one time
          outstanding;

              (iii)  Liens imposed by law, such as materialmen's, mechanics',
          carriers', workmen's and repairmen's Liens and other similar Liens
          arising in the ordinary course of business securing obligations which
          are not overdue or which have been fully bonded and are being 
          contested in good faith;

   
              (iv)   purchase money Liens upon or in property acquired and
          held  by the Issuer in the ordinary course of business to secure the 
          purchase price of such property or to secure Indebtedness incurred 
          solely for the purpose of financing the acquisition of any such 
          property to be subject to such Liens, or Liens existing on any such 
          property at the time of acquisition, or extensions, renewals or
          replacements of any of the foregoing for the same or a lesser amount,
          provided that no such Lien shall extend to or cover any property
          other than the property being acquired and no such extension, renewal
          or replacement shall extend to or cover property not theretofore
          subject to the Lien being extended, renewed or replaced, and
          provided, further, that the aggregate principal
    

<PAGE>   43
                                     43
      
       amount of the Indebtedness at any one time outstanding secured by Liens  
       permitted by this clause (iv) shall not exceed $10,000,000; and

   
              (v)    Liens not otherwise permitted by clauses (i) through (iv)
       of this Section securing Indebtedness of the Issuer; provided that on
       the date such Liens are created, and after giving effect to such
       Indebtedness, the aggregate principal amount at maturity of all of the
       secured Indebtedness of the Issuer at such date shall not exceed 5% of
       Consolidated Net Tangible Assets at such date.
    

   
              SECTION 4.02.  Limitation on Consolidation, Merger, Sale or
Conveyance of Assets.  So long as any of the X-TRAS are Outstanding and until
senior unsecured debt of the Issuer is rated BBB- or above (or an equivalent
rating) by Standard & Poor's and one Other Rating Agency (or, if Standard &
Poor's shall change its rating system, an equivalent of such rating then
employed by such organization), at which time the Issuer will be permanently
released from the provisions of this Section 4.02, and subject also to Article
Nine of the Indenture,  the Issuer shall not consolidate with or merge into any
other Person or sell, lease or convey the property of the Issuer in the
entirety or substantially as an entirety, unless (i) immediately after giving
effect to such transaction the Consolidated Net Worth of the surviving entity
is at least equal to the Consolidated Net Worth of the Issuer immediately 
prior to the transaction, and (ii) after giving effect to such transaction, 
the surviving entity would be entitled to incur at least one dollar of 
additional Indebtedness (other than revolving Indebtedness to banks) without 
violation of the limitations in Section 4.03 hereof.

                                     44

   
              SECTION 4.03.  Limitation on Consolidated Indebtedness.  (a)  So
long as any of the senior unsecured debt of the Issuer is Outstanding and until
the senior unsecured debt of the Issuer is rated BBB- or above (or an equivalent
rating) by Standard & Poor's and one Other Rating Agency (or, if Standard &
Poor's shall change its rating system, an equivalent of such rating then
employed by such organization), at which time the Issuer will be permanently
released from the provisions of this Section 4.03, the Issuer shall not, and
shall not permit any Consolidated Subsidiary of the Issuer to, issue, create,
assume, guarantee, incur or otherwise become liable for (collectively,
"issue"), directly or indirectly, any Indebtedness unless the Consolidated
Coverage Ratio of the Issuer and its Consolidated Subsidiaries for the four
consecutive fiscal quarters immediately preceding the issuance of such
Indebtedness (as shown by a pro forma consolidated income statement of the
Issuer and its Consolidated Subsidiaries for the four most recent fiscal
quarters ending at least 30 days prior to the issuance of such Indebtedness
after giving effect to (i) the issuance of such Indebtedness and (if
applicable) the application of the net proceeds thereof to refinance other
Indebtedness as if such Indebtedness was issued at the beginning of the period,
(ii) the issuance and retirement of any other Indebtedness since the first day
of the period as if such Indebtedness was issued or retired at the beginning of
the period and (iii) the acquisition of any company or business acquired by the
Issuer or any Subsidiary since the first day of the period (including
giving effect to the pro forma historical earnings of such company or
business), including any acquisition which will be consummated
contemporaneously with the issuance of such Indebtedness, as if in each case
such acquisition occurred at the beginning of the period) exceeds a ratio of
1.7 to 1.0.

                                     45

              (b)    Notwithstanding the foregoing paragraph, the Issuer or any
Restricted Subsidiary may issue, directly or indirectly, the following
Indebtedness:

              (1)    Indebtedness of the Issuer to banks not to exceed
       $1,000,000,000 in aggregate outstanding principal amount at any
       time; 

   
              (2)    Indebtedness (other than Indebtedness described in
       clause (1) of this Subsection) outstanding on the date of this Sixth
       Supplemental Indenture, as set forth on Schedule 4.03(b)(2) attached
       hereto and made a part hereof, and Indebtedness issued in exchange for,

              SECTION 4.04.  Limitation on Restricted Payments.  (a) So long 
as the X-TRAS are Outstanding and until senior unsecured debt of the 
Issuer is rated BBB- or above (or an equivalent rating) by Standard &
Poor's and one Other Rating Agency (or, if Standard & Poor's shall change its
rating system, an equivalent of such rating then employed by such
organization), at which time the Issuer will be permanently released from the
provisions of this Section 4.04, the Issuer shall not, and shall not permit any
Restricted Subsidiary of the Issuer, directly or indirectly, to (i) declare or
pay any dividend or make any distribution on the Capital Stock of the Issuer to
the direct or indirect holders of its Capital Stock (except dividends or
distributions payable solely in its Non-Convertible Capital Stock or in
options, warrants or other rights to purchase such Non-Convertible Capital
Stock and except dividends or distributions payable to the Issuer or a
Subsidiary), (ii) purchase, redeem or otherwise acquire or retire for value any
Capital Stock of the Issuer, or (iii) purchase, repurchase, redeem, defease or
otherwise acquire or retire for value, prior to scheduled maturity or scheduled
repayment thereof, any Subordinated Indebtedness (any such dividend,
distribution, purchase, redemption, repurchase, defeasing, other acquisition or
retirement being hereinafter referred to as a "Restricted Payment") if at the
time the Issuer or such Subsidiary makes such Restricted Payment:

              (1)    an Event of Default, or an event that with the lapse of
       time or the giving of notice or both would constitute an Event of
       Default, shall have occurred and be continuing (or would result
       therefrom); or

              (2)    the aggregate amount of such Restricted Payment and all
       other Restricted Payments made since May 6, 1997 would exceed the sum
       of:

<PAGE>   49

                                     49

                     (A)    $100,000,000;

                     (B)    100% of Consolidated Net Income, accrued during the
              period (treated as one accounting period) from May 6, 1997 to the
              end of the most recent fiscal quarter ending at least 45 days
              prior to the date of such Restricted Payment (or, in case such
              sum shall be a deficit, minus 100% of the deficit); and

                     (C)    the aggregate Net Cash Proceeds received by the
              Issuer from the issue or sale of or contribution with respect to
              its Capital Stock subsequent to May 6, 1997.

For the purpose of determining the amount of any Restricted Payment not in the
form of cash, the amount shall be the fair value of such Restricted Payment as
determined in good faith by the Board of Directors, provided that if the value
of the non-cash portion of such Restricted Payment as determined by the Board
of Directors is in excess of $25 million, such value shall be based on the
opinion from a nationally recognized firm experienced in the appraisal of
similar types of transactions.

              (b)    The provisions of Section 4.04(a) shall not prohibit:


                     (i)    any purchase or redemption of Capital Stock of the
              Issuer made by exchange for, or out of the proceeds of the
              substantially concurrent sale of, Capital Stock of the Issuer
              (other than Redeemable Stock or Exchangeable Stock); provided,
              however, that such purchase or redemption shall be excluded from
              the calculation of the amount of Restricted Payments;

<PAGE>   50


                                     50

                     (ii)   dividends or other distributions paid in respect of
              any class of the Issuer's Capital Stock issued in respect of the
              acquisition of any business or assets by the Issuer or a
              Restricted Subsidiary if the dividends or other distributions
              with respect to such Capital Stock are payable solely from the
              net earnings of such business or assets;

                     (iii)  dividends paid within 60 days after the date of
              declaration thereof if at such date of declaration such dividend
              would have complied with this Section; provided, however, that at
              the time of payment of such dividend, no Event of Default shall
              have occurred and be continuing (or result therefrom), and
              provided further, however, that such dividends shall be included
              (without duplication) in the calculation of the amount of
              Restricted Payments; or

                     (iv)   payments pursuant to the Tax-Sharing Agreement.

              SECTION 4.05.  Limitation on Asset Sales.  So long as any of the
X-TRAS are outstanding, the Issuer may not sell, transfer or otherwise dispose
of any property or assets of the Issuer, including Capital Stock of any
Consolidated Subsidiary, in one transaction or a series of transactions in an
amount which exceeds $50,000,000 (an "Asset Sale") unless the Issuer shall
(i) apply an amount equal to such excess Net Cash Proceeds to permanently repay
Indebtedness of a Consolidated Subsidiary or Indebtedness of the Issuer which
is pari passu with the X-TRAS or (ii) invest an equal amount not so used in
clause (i) in property or assets of related business within 24 months after the
date of the Asset Sale (the "Application Period") or (iii) apply such excess
Net Cash Proceeds not so used in (i) or (ii) (the "Excess Proceeds") to make an
offer (the 

<PAGE>   51
                                     51


   
"Excess Proceeds Offer"), within 30 days after the end of the
Application Period, to purchase (the "Excess Proceeds Repurchase") from the
Holders on a pro rata basis an aggregate principal amount of X-TRAS on the
Excess Proceeds Purchase Date (as defined herein) equal to the Excess Proceeds
on such date, at a purchase price equal to 100% of the principal amount of the
X-TRAS on the Excess Proceeds Purchase Date and unpaid interest, if any, to
such date (the "Excess Proceeds Repurchase Price") plus (in the aggregate with
all other X-TRAS repurchased pursuant to such Excess Proceeds Offer) 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 Issuer, the
Indenture Trustee and the Pass Through Trustee by 10 a.m., New York City time,
on such date.  The Notional Amount used to determine the ISDA Amount shall be
equal to the aggregate principal amount of X-TRAS tendered for repurchase and
not withdrawn. The Issuer shall only be required to make an offer to purchase
X-TRAS from Holders pursuant to subsection (iii) if the Excess Proceeds equal
or exceed $25,000,000 at any given time.  
    
        
              (a)    Within 30 days after the end of the Application Period,
       the Issuer 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:

                    (i)    that the Issuer is making an Excess Proceeds Offer

                                     52

                    (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 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)   Holders electing to have X-TRAS repurchased must deliver 
       a written notice (the "Excess Proceeds Purchase Notice") to the
       Paying Agent (initially the Indenture Trustee) at its corporate trust
       office in Detroit, Michigan, or any other office of the 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 X-TRAS 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 Issuer
       pursuant to the Exceeds Proceeds Offer provisions of the Indenture; and
       (iii) unless the X-TRAS are represented by one or more Global Notes, the
       certificate numbers of the X-TRAS to be delivered by the Holder thereof
       for repurchase by the Issuer.  Any Excess Proceeds Purchase Notice may
       be withdrawn by the Holder by a written notice of withdrawal delivered
       to the Paying Agent not later than three Business Days prior to the 
       Excess Proceeds Purchase Date.  The notice of withdrawal shall state 
       the principal amount and, if applicable, the certificate numbers of the
       X-TRAS

                                     53

   
       as to which the withdrawal notice relates and the principal amount of 
       such X-TRAS, if any, which remain subject to an Excess Proceeds Purchase
       Notice.
    

              (c)    Payment of the Excess Proceeds Purchase Price for X-TRAS
       for which a Excess Proceeds Purchase Notice has been delivered and not
       withdrawn is conditioned upon delivery of such X-TRAS (together with
       necessary endorsements) to the Paying Agent at its office in Detroit,
       Michigan, or any other office of the 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 such X-TRAS
       will be made promptly following the later of the Excess Proceeds
       Purchase Date or the time of delivery of such X- TRAS.  If the Paying
       Agent holds, in accordance with the terms of the Indenture, money
       sufficient to pay the Excess Proceeds Purchase Price 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 Issuer 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.

than 100% of the principal amount of the X-TRAS plus accrued interest to the 
Redemption Date.   The Notional Amount used to determine the ISDA Amount shall 
be equal to the aggregate principal amount of X-TRAS redeemed.
    
        
              (c)    If the X-TRAS are extended until the Extended Stated
Maturity, the Issuer shall have the option (the "FD Redemption Option"), in
lieu of permitting the X-TRAS to be remarketed in accordance with Article VIII
of this Sixth Supplemental Indenture, to redeem the X-TRAS in whole on the
Initial Stated Maturity, by irrevocable notice given to the Indenture Trustee,
the Pass Through Trustee, the Extension Option Buyer and the Calculation Agent
not later than the Remarketing Deadline, at a redemption price, payable in
cash, equal to the sum of (i) 100% of the principal amount of the X-TRAS being
redeemed together with accrued interest, if any, thereon to the Initial Stated
Maturity plus (ii) the ISDA

Amount, if any, as of the Exercise Date (as calculated by the
Calculation Agent and notified to the Issuer, the Indenture Trustee and the
Pass Through Trustee within five Business Days thereafter), which redemption
price shall be payable at the Initial Stated Maturity.  The Notional Amount
used to determine the ISDA Amount shall be the aggregate principal amount of
the X-TRAS outstanding as of the Exercise Date.

   
              SECTION  7.02.   Put Option of Holders.  If the maturity of the
X-TRAS is extended and for any reason the Pass Through Trustee does not receive 
an amount in cash equal to the principal amount of and interest on the 
X-TRAS plus the ISDA Amount by the Remarketing on the Initial Stated Maturity,
all of the outstanding X-TRAS at a purchase price equal to 100% of the 
principal amount of and accrued interest on the X-TRAS to the Initial Stated 
Maturity.

                            REMARKETING OF X-TRAS

   

              SECTION 8.01.   Remarketing of X-TRAS.  In the event that the 
maturity of the X-TRAS is extended until the Extended Stated Maturity, then, 
unless the Issuer exercises the FD Redemption Option (which option the Issuer 
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 Indenture Trustee and the Pass Through
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 Issuer pursuant to such sentence, will be sufficient to enable
the Pass Through Trustee to make the Final Distribution on the Certificates. 
Accordingly, the Issuer shall be obligated to pay to the Pass Through Trust,
simultaneously with the closing of the remarketing, an amount equal to the
interest 
    

<PAGE>   61

                                     61

   
that would have accrued on the X-TRAS had they been held by the Pass
Through 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 Issuer shall be entitled to receive 
any amounts earned in respect of the investment by the Pass Through Trustee of
the Required Remarketing Proceeds and the ISDA Amount in U.S. Government
Obligations pursuant to clause (d) below. In no event shall the Issuer shall
have any obligation to pay the principal  amount of the X-TRAS to the Pass
Through Trust on the Initial Stated Maturity. 
    

        
              SECTION 8.02.  Remarketing Procedure.   The X-TRAS will be
remarketed in accordance with the following procedure (the "Remarketing
Procedure"):

              (a)    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 Issuer with non-binding indications of the interest 

<PAGE>   62
                                     62

rate and discount or premium at which it believes it could remarket the X-TRAS 
in order to yield the Required Remarketing Proceeds.

              (b)    Morgan Stanley & Co. Incorporated shall act as the
Remarketing Agent for the X-TRAS unless, no later than [60] days prior to the
Initial Stated Maturity, the Issuer shall select another investment banking
institution to remarket the X-TRAS or exercise the FD Redemption Option in
accordance with the provisions of Section 7.01(c) hereof.

              (c)    No later than 15 days prior to the Remarketing Deadline,
the Remarketing Agent will commence marketing of the X-TRAS to investors.

   
              (d)    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.  Upon completion of the
remarketing, the net proceeds thereof, together with the amount payable by the
Issuer equal to the interest that would have accrued on the X-TRAS had they
been held by the Pass Through Trust to the Initial Stated Maturity, will be
deposited with the Pass Through Trustee and invested in Government Obligations 
having a maturity as close as possible equal to the number of days between the 
date of such investment and the Initial Stated Maturity.  
    

              (e)    The Remarketing Agent will be entitled to underwriting
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 (i) below,
it shall be entitled to underwriting commissions, payable at 

<PAGE>   63

                                     63

settlement of such purchase, which will be determined at the time it
gives notice of its offer pursuant to clause (i) below and shall be consistent
with then prevailing market practices.

              (f)    The Issuer 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 (i)
below) by Morgan Stanley & Co. Incorporated in connection with the remarketing
or purchase of the X-TRAS, as applicable, including, without limitation, (1)
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, (ii) 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, (iii)
providing promptly upon request updated consolidated financial statements to
the date of its latest report filed with the Commission and (iv) to the extent
the Issuer 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 Issuer for road show and
one-on-one presentations.

                                     64

              (g)    The Issuer 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 Issuer shall
notify the Remarketing Agent of such request no later than [70] days prior to
the Final Distribution Date.  The Issuer 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.

              (h)    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 bearing a reset interest rate specified by Morgan 
Stanley & Co. Incorporated on a date not later than the Remarketing Deadline
for net 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, (i) the Company shall have delivered an 
irrevocable notice of redemption pursuant to Section 7.01(c) of this Sixth 
Supplemental Indenture or (B) any other party shall have remarketed the X-TRAS 
bearing a reset interest rate lower than or equal to that specified by Morgan 
Stanley & Co. Incorporated for net proceeds in cash at least equal to the 
Required Remarketing Proceeds.

   
              (i)     The remarketed X-TRAS will bear interest at the reset
interest rate commencing upon the date of closing of the remarketing.  For the
avoidance of 
    

<PAGE>   65
                                     65

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.

the Holders of Securities of any Series; and provided further that  no
such supplemental indenture referred to in the first clause of this sentence
and in clauses (a) through (f) of Section 8.1 of the Original Indenture which

action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required pursuant to this
<PAGE>   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.

         (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.

         (iii)  the preparation for filing by the Trust and the execution on

    any other national stock exchange or the NASDAQ National Market or any
    other automated quotation system for listing upon notice of issuance of
    any Certificates and filing with such exchange or self-regulatory
    organization such notifications and documents as may be necessary from
    time to time to maintain such listing;
    
         (iv) the preparation for filing by the Trust with the SEC and the

association taxable as a corporation or is other than a grantor trust for
United States federal income tax purposes and so that the Certificates will be
<PAGE>   25

                                      19

   
treated as indebtedness of the Company for United States federal income tax

take any action, not inconsistent with applicable law, the Certificate of Trust
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.

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,

         (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

                                     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).

         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:
<PAGE>   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.
    

<PAGE>   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
    

<PAGE>   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).

the Certificateholders a Certificate Account as one or more
non-interest-bearing accounts.  The Trustee shall hold the Certificate Account

Certificateholders a Special Payments Account as one or more accounts, which

         (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

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 
    

<PAGE>   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 
<PAGE>   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 
<PAGE>   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
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 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
made pursuant to the Company's exercise of its right of redemption pursuant to
Section 7.01(b) of the Indenture, on the date of payment of the redemption
price thereunder; (ii) in the event of an ISDA Payment made pursuant to Section

pursuant to Section 5.03 of the Indenture, on the date of deposit of such
payment with the Trust.

                                 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.
    

<PAGE>   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,     
<PAGE>   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
<PAGE>   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:
    

<PAGE>   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     
<PAGE>   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.

                                 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.

         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 
<PAGE>   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:
<PAGE>   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
    on the X-TRAS, or
    
         (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);
<PAGE>   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.

                                 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
<PAGE>   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

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:

    taking, suffering or omitting any action hereunder, the Trustee (unless
    other evidence be herein 
<PAGE>   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;

    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;

    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
<PAGE>   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 
<PAGE>   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.
<PAGE>   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 
<PAGE>   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.
<PAGE>   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.  
<PAGE>   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;
<PAGE>   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-
    

<PAGE>   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

    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

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.

         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;
<PAGE>   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.

                                  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 
    

<PAGE>   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"):
    

<PAGE>   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.
<PAGE>   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.
    

<PAGE>   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.

         Section 11.02.  Termination of the Trust.  The respective obligations
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.

                    to in the within-mentioned Agreement.

                          [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

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.
