Attest:

   SECTION 2.04.  Form of Reverse of 2004 Note.
   This _____% Senior Unsecured Note Due 2004 is one of a duly authorized issue
of securities of the Issuer (herein called the "2004 Notes"), issued and to be
issued under an Indenture, dated as of September 15, 1992, as supplemented by
certain supplemental indentures, including the Fourth Supplemental Indenture,
dated as of September___, 1997 (herein collectively referred to as the
"Indenture"), between the Issuer and NBD Bank, a Michigan banking corporation
(formerly known as NBD Bank, National Association), as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Issuer, the Trustee, the Holders of the 2004
Notes and of the terms upon which the 2004 Notes are, and are to be,
authenticated and delivered.  This 2004 Note is one of the series designated on
the face hereof, limited in aggregate principal amount to $180,000,000.

   The 2004 Notes are subject to redemption at the option of the Issuer, in
whole or in part, upon not more than 60 nor less than 30 days' notice
as provided in the Indenture at any time and from time to time, at a redemption
price equal to 100% of the principal amount of such 2004 Notes being redeemed
plus the Applicable Premium, if any, thereon at the time of redemption,
together with accrued interest, if any, thereon to the redemption date, but
interest installments whose Stated Maturity is on or prior to such redemption
date will be payable to the Holder of record at the



                                    -22-

   23

close of business on the relevant Record Date referred to on the face hereof,
all as provided in the Indenture.  In no event will the redemption price ever
be less than 100% of the principal amount of the 2004 Notes plus accrued
interest, if any, to the redemption date.

 The following definitions are used to determine the Applicable Premium:

   "Applicable Premium" means, with respect to a 2004 Note (or portion thereof)
at any time, the excess of (A) the present value at such time of the principal
amount of such 2004 Note (or portion thereof) being redeemed plus all
interest payments due on such 2004 Note (or portion thereof), computed using a
discount rate equal to the Treasury Rate plus 50 basis points, over (B) the
principal amount of such 2004 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)
which has become publicly available at least two business days prior to the
date fixed for redemption 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 2004 Notes; provided,
however, that if the average life to stated maturity of the 2004 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.

   In the event of redemption of this 2004 Note in part only, a new 2004 Note
for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

                                    -23-

   24


   If a Change in Control occurs, the Issuer shall notify the Holder of this
2004 Note of such occurrence and such Holder shall have the right to require
the Issuer to make a Required Repurchase of all or any part of this 2004 Note
at a Change in Control Purchase Price equal to 101% of the principal amount of
this 2004 Note to be so purchased as more fully provided in the Indenture and
subject to the terms and conditions set forth therein.  In the event of a
Required Repurchase of only a portion of this 2004 Note, a new 2004 Note or
Notes for the unrepurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

   If an Event of Default with respect to this 2004 Note shall occur and be
continuing, the principal of this 2004 Note may be declared due and payable in
the manner and with the effect provided in the Indenture.

   In any case where any Interest Payment Date, repurchase date, Stated
Maturity or Maturity of any 2004 Note shall not be a Business Day at any Place
of Payment, then (notwithstanding any other provision of the Indenture or this
2004 Note), 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 2004 Note or (ii) certain restrictive covenants and
Events of Default with respect to this 2004 Note, in each case upon compliance
with certain conditions set forth therein.


                                    -24-


   25


   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 2004 Notes under the
Indenture at any time by the Issuer and the 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).

   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.

   As set forth in, and subject to, the provisions of the Indenture, no Holder
of any 2004 Note 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 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 Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the Holders of a majority in principal amount of the Outstanding
Securities of each affected 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


                                    -25-

   26

enforcement of payment of the principal of (and premium, if any) or any
interest on this 2004 Note on or after the respective due dates expressed
herein.

   No reference herein to the Indenture and no provision of this 2004 Note 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 2004 Note 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 2004 Note is registerable in the Security Register,
upon surrender of this 2004 Note 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 2004 Note 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 2004 Notes 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 2004 Notes 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, 2004 Notes are
exchangeable for a like aggregate principal amount of 2004 Notes 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.

                                    -26-

transfer of any 2004 Note or any portion thereof selected, called or being
called for redemption, except in the case of any 2004 Note to be redeemed in

   Prior to due presentment of this 2004 Note for registration of transfer, the
Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
Person in whose name this 2004 Note is registered as the owner hereof for all
purposes, whether or not this 2004 Note be overdue, and neither the Issuer, the

                                  ARTICLE III

                               CHANGE OF CONTROL

   SECTION 3.01.  Change of 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 a 2004 Note shall have the right to require that
the Issuer repurchase (a "Required Repurchase") all or any part of such
Holder's 2004 Note at a repurchase price payable in cash equal to 101% of the
principal amount of such 2004 Note plus accrued interest to the Purchase Date
(the "Change in Control Purchase Price").

   (a)  Within 30 days following the Change in Control Date, the Issuer shall
 mail a notice (the "Required Repurchase Notice") to each Holder with a copy to
 the Trustee 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
   2004 Notes at the Change of Control Purchase Price;

        (ii)  the Change of 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 "Purchase Date");

        (iv)  the name and address of the Paying Agent; and

        (v)  the procedures that Holders must follow to cause the 2004 Notes 
   to be repurchased, which shall be consistent with this Section and the 
   Indenture.


                                    -28-

   29


   (b)  Holders electing to have a 2004 Note repurchased must deliver a written
notice (the "Change in Control Purchase Notice") to the Paying Agent 
(initially the 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 Purchase Date.  The Change in Control Purchase 
Notice shall state: (i) the portion of the principal amount of any 2004 Notes 
to be repurchased, which portion must be $1,000 or an integral multiple 
thereof; (ii) that such 2004 Notes are to be repurchased by the Issuer pursuant
to the change in control provisions of the Indenture; and (iii) unless
the 2004 Notes are represented by one or more Global Notes, the certificate
numbers of the 2004 Notes 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 Purchase Date.  The notice of
withdrawal shall state the principal amount and, if applicable, the certificate
numbers of the 2004 Notes as to which the withdrawal notice relates and the
principal amount of such 2004 Notes, if any, which remains subject to a Change
in Control Purchase Notice.

   If a 2004 Note is represented by a Global Note (as described in Article VI
below), the Depositary or its nominee will be the Holder of such 2004 Note and
therefore will be the only entity that can elect a Required Repurchase of such
2004 Note.  To obtain repayment pursuant to this Section 3.01 with respect to
such 2004 Note, the beneficial owner of such 2004 Note must provide to the
broker or other entity through which it holds the beneficial interest in such
2004 Note (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


                                    -29-

   30

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 3.01.  Such broker or other entity will provide to the Paying
Agent (i) the Change of Control Purchase Notice received from such beneficial
owner and (ii) a certificate satisfactory to the 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 of the Change of Control Purchase Price for a 2004 Note for
which a Change in Control Purchase Notice has been delivered and not withdrawn
is conditioned (except in the case of a 2004 Note represented by one or more
Global Notes) upon delivery of such 2004 Note (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 Purchase Date) after the delivery of such
Change in Control Purchase Notice.  Payment of the Change of Control Purchase
Price for such 2004 Note will be made promptly following the later of the
Purchase Date or the time of delivery of such 2004 Note.  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 2004 Note on the Business Day
following the 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 Change of Control Purchase Price upon delivery of the
2004 Note).

   (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


                                    -30-

   31

 applicable in connection with any offer by the Issuer to repurchase 2004 Notes
 at the option of Holders upon a Change in Control.

   (e) No 2004 Note 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 2004 Notes).

   SECTION 4.02.  Limitation on Certain Liens.  (a)  So long as any of the 2004

exist any lien, mortgage, pledge, security interest, conditional sale, title
retention agreement or other charge or encumbrance of any kind, 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 (hereinafter in this
Section referred to as a "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 2004
Notes shall (so long as any such other 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:


                                    -31-

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

 (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

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 4.03.  Limitation on Consolidation, Merger, Sale or Conveyance.  So
long as any of the 2004 Notes are Outstanding and until the 2004 Notes are
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, 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

of the 2004 Notes are Outstanding and until the 2004 Notes are 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 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


                                    -33-


   34

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.

   (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

 Indebtedness issued in exchange for, or the proceeds of which are used to
 refund or refinance, any Indebtedness permitted by this clause (2); provided,
 however, that (i) the principal amount (or accreted value in the case of

 that, in the case of Indebtedness of the Issuer owed to and held
 by a Subsidiary, (i) any subsequent issuance or transfer of any Capital Stock
 that results in any such Subsidiary ceasing to be a Subsidiary or (ii) any
 transfer of such Indebtedness (except to the Issuer or a Subsidiary) shall be
 deemed for the purposes of this Subsection to constitute the issuance of such
 Indebtedness by the Issuer;

   (4)  Indebtedness of the Issuer issued in exchange for, or the proceeds of
 which are used to refund or refinance, Indebtedness of the Issuer issued in
 accordance with Subsection (a) of this Section, provided that (i) the

 of Indebtedness issued at a discount) of the Indebtedness so issued shall not
 exceed the principal amount (or accreted value in the case of Indebtedness
 issued at a discount) of, premium, if any, and accrued but unpaid interest on,
 the Indebtedness so exchanged, refunded or refinanced and (ii) the 
 Indebtedness so issued (A) shall not mature prior to the stated maturity of 
 the Indebtedness so exchanged, refunded or refinanced and (B) shall have an 
 Average Life equal to or greater than the remaining Average Life of the 
 Indebtedness so exchanged, refunded or refinanced.

   (6) Indebtedness of a Consolidated Subsidiary issued to acquire, develop,
 improve, construct or to provide working capital for a gas, oil or electric
 generation, exploration, production, distribution, storage or transmission

 other Designated Enterprises Subsidiary;

   (7)  Indebtedness of a Person existing at the time at which such

 Consolidated Subsidiary;

   (8) Indebtedness issued by the Issuer not to exceed $150,000,000 in aggregate
 principal amount at any time; and


                                    -36-

    SECTION 4.05.  Limitation on Restricted Payments.  (a) So long as the 2004
Notes are Outstanding and until the 2004 Notes are 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 4.05, 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



                                    -37-
   38


    (2)  the aggregate amount of such Restricted Payment and all other
 Restricted Payments made since the date of this Fourth Supplemental Indenture
 would exceed the sum of:

    (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
   the date of this Fourth Supplemental Indenture.

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 4.05(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


                                    -38-

   39

    Redeemable Stock or Exchangeable Stock); provided, however, that such
    purchase or redemption shall be excluded from the calculation of the amount
    of Restricted Payments;

        (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 4.06. Limitation on Asset Sales.  So long as any of the 2004 Notes
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 2004 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


                                    -39-

   40

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 from
the Holders on a pro rata basis an aggregate principal amount of 2004 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 2004 Notes on the
relevant purchase date and unpaid interest, if any, to the purchase date.  The
Issuer shall only be required to make an offer to purchase 2004 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 Issuer in making an offer to purchase
2004 Notes from the Holders with Excess Proceeds, and for the acceptance of
such offer by the Holders, shall be the same as those set forth in Section 3.01
herein with respect to a Change in Control.

                                   ARTICLE V

                          ADDITIONAL EVENTS OF DEFAULT
                         WITH RESPECT TO THE 2004 NOTES

   SECTION 5.01.  Definition.  All of the events specified in clauses (a)
through (h) of Section 5.1 of the Original Indenture shall be "Events of
Default" with respect to the 2004 Notes.

   SECTION 5.02. Amendments to Section 5.1 of the Original Indenture.  Solely
for the purpose of determining Events of Default with respect to the 2004
Notes, paragraphs (e), (f) and (h) of Section 5.1 of the Original Indenture
shall be amended such that each and every reference therein to the Issuer shall
be deemed to mean either the Issuer or Consumers.

                                   ARTICLE VI

                                  GLOBAL NOTES

   The 2004 Notes will be issued initially in the form of Global Notes.
"Global Note" means a registered 2004 Note evidencing one or more 2004 Notes
issued to a depositary (the "Depositary") or its nominee, in accordance with
this Article and bearing the legend prescribed in this Article.  One or more
Global Notes will represent all 2004 Notes.  The Issuer shall execute and the
Trustee shall, in accordance with this Article and the Issuer Order with
respect to the 2004 Notes, authenticate and deliver one or more Global Notes in
temporary or permanent form that (i) shall represent and shall be denominated
in an aggregate amount equal to the aggregate principal amount of the 2004
Notes to be represented by such Global Note or Notes, (ii) shall be registered
in the name of the Depositary for such Global Note or Notes or the nominee of
such Depositary, (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instructions and (iv) shall bear a legend
substantially to the following effect: "Unless the Global 2004 Note is
presented by an authorized representative of the Depository to the Issuer or
its agent for registration of transfer, exchange or payment, and any 2004 Note
issued is registered in the name of a nominee of the Depository, or in such
other name as is requested by an authorized representative of the Depository
(and any payment is made to the nominee of the Depository, or to such other
entity as is requested by an authorized representative of the Depository), any
transfer, pledge or other use hereof for value or otherwise by or to any Person
is wrongful inasmuch as the registered owner hereof has an interest herein."

   Notwithstanding Section 2.8 of the Indenture, unless and until it is
exchanged in whole or in part for 2004 Notes in definitive form, a Global Note
representing one or more 2004 Notes may not be transferred except as a whole by
the Depositary, to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such

                                    -41-

   42

Depositary or any such nominee to a successor Depositary for 2004 Notes or a
nominee of such successor Depositary.

   If at any time the Depositary for the 2004 Notes is unwilling or unable to
continue as Depositary for the 2004 Notes, the Issuer shall appoint a successor
Depositary with respect to the 2004 Notes.  If a successor Depositary for the
2004 Notes is not appointed by the Issuer by the earlier of (i) 90 days from
the date the Issuer receives notice to the effect that the Depositary is
unwilling or unable to act, or the Issuer determines that the Depositary is
unable to act or (ii) the effectiveness of the Depositary's resignation or
failure to fulfill its duties as Depositary, the Issuer will execute, and the
Trustee, upon receipt of a Issuer Order for the authentication and delivery of
definitive 2004 Notes, will authenticate and deliver 2004 Notes in definitive
form in an aggregate principal amount equal to the principal amount of the
Global Note or Notes representing such 2004 Notes in exchange for such Global
Note or Notes.

   The Issuer may at any time and in its sole discretion determine that the
2004 Notes issued in the form of one or more Global Notes shall no longer be
represented by such Global Note or Notes.  In such event the Issuer will
execute, and the Trustee, upon receipt of a Issuer Order for the authentication
and delivery of definitive 2004 Notes, will authenticate and deliver 2004 Notes
in definitive form in an aggregate principal amount equal to the principal
amount of the Global Note or Notes representing such 2004 Notes in exchange for
such Global Note or Notes.

   The Depositary for such 2004 Notes may surrender a Global Note or Notes for
such 2004 Notes in exchange in whole or in part for 2004 Notes in definitive
form on such terms as are acceptable to the Issuer and such Depositary.
Thereupon, the Issuer shall execute, and the Trustee shall authenticate and
deliver, without service charge:

                                    -42-


   43


      (i)  to each Person specified by such Depositary a new 2004 Note or
   Notes, of any authorized denomination as requested by such Person in
   aggregate principal amount equal to and in exchange for such Person's
   beneficial interest in the Global Note; and

      (ii)  to such Depositary a new Global Note in a denomination equal to the
   difference, if any, between the principal amount of the surrendered Global
   Note and the aggregate principal amount of 2004 Notes in definitive form
   delivered to Holders thereof.

   In any exchange provided for in this Article, the Issuer will execute and
the Trustee will authenticate and deliver 2004 Notes in definitive registered
form in authorized denominations.

   Upon the exchange of a Global Note for 2004 Notes in definitive form, such
Global Note shall be cancelled by the Trustee.  2004 Notes in definitive form
issued in exchange for a Global Note pursuant to this Article shall be
registered in such names and in such authorized denominations as the Depositary
for such Global Note, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee or Security Registrar.
The Trustee shall deliver such 2004 Notes to the persons in whose names such
2004 Notes are so registered.

                                 ARTICLE VII

                                 DEFEASANCE


   All of the provisions of Article Ten of the Original Indenture shall be
applicable to the 2004 Notes.  Upon satisfaction by the Issuer of the
requirements of Section 10.1(c) of the Indenture, in connection with any
covenant defeasance (as provided in Section 10.1(c) of the Indenture), the
Issuer shall be released from its obligations under Article Nine of the
Original Indenture and

                                    -43-

   44

under Articles III and IV of this Fourth Supplemental Indenture with respect to
the 2004 Notes.
