         SECTION 204. Form of Reverse of General Term Note.

         This General Term Note(R), Series F is one of a duly authorized issue
of securities of the Company (herein called the "General Term Notes"), issued
and to be issued in one or more series under an Indenture, dated as of January
15, 1994, as supplemented by certain supplemental indentures, including the
Sixth Supplemental Indenture, dated as of November 9, 2000 (herein collectively
referred to as the "Indenture"), between the Company and The Chase Manhattan
Bank, a New York banking corporation, 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 Company, the Trustee, the Holders of the General Term Notes
and of the terms upon which the General Term Notes are, and are to be,
authenticated and delivered. This General Term Note is one of the series
designated on the face hereof, limited in aggregate principal amount to
$300,000,000.

         [If applicable, insert -- The General Term Notes of this series are
subject to redemption upon not more than 60 nor less than 30 days' notice as
provided in the Indenture, at any time [on or after __________, _____,] as a
whole or in part from time to time, at the election of the Company, at the
following



                                       20

Redemption Prices (expressed as percentages of the principal amount): If
redeemed [on or before              ,    %, and if redeemed] during the 12-month
period beginning              of the years indicated,

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












and thereafter at a Redemption Price equal to    % of the principal amount,
together in the case of any such redemption with accrued interest to the
Redemption Date, but interest installments whose Stated Maturity is on or prior
to such Redemption Date will be payable to the Holders of such General Term
Notes, or one or more Predecessor Securities, of record at the close of business
on the relevant Record Dates referred to on the face hereof, all as provided in
the Indenture.]

         [Notwithstanding the foregoing, the Company may not, prior to
          , redeem this General Term Note as a part of, or in anticipation of,
any refunding operation by the application, directly or indirectly, of moneys
borrowed having an effective interest cost to the Company (calculated in
accordance with generally accepted financial practice) of less than the
effective interest cost to the Company (similarly calculated) of this General
Term Note.]

         [If the General Term Note is subject to redemption, insert -- In the
event of redemption of this General Term Note in part only, a new General Term
Note or Notes of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder hereof upon the cancellation hereof.]

         If a Change in Control occurs, the Company shall notify the Holder of
this General Term Note of such occurrence and such Holder shall have the right
to require the Company to make a Required Repurchase of all or any part of this



                                       21
<PAGE>   22

General Term Note at a Change in Control Purchase Price equal to 101% of the
principal amount of this General Term 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 General
Term Note, a new General Term Note or Notes for the unrepurchased portion hereof
will be issued in the name of the Holder hereof upon the cancellation hereof.

         [If this General Term Note is subject to redemption upon exercising a
Survivor's Option, insert -- As more fully provided in the Indenture and subject
to the terms and conditions set forth therein, the Company will repay this
General Term Note (or portion thereof) properly tendered for repayment by or on
behalf of the person (the "Representative") that has authority to act on behalf
of a deceased owner of the beneficial interest in this General Term Note under
the laws of the appropriate jurisdiction (including, without limitation, the
trustee of a personal trust, the personal representative, executor, surviving
joint tenant or surviving tenant by the entirety of such deceased beneficial
owner) at a price equal to 100% of the principal amount hereof plus accrued
interest to the date of such repayment. In order for a Holder to exercise the
Survivor's Option, the deceased beneficial owner or his or her Representative
must have individually or collectively held the General Term Note for 120 days.
The Company may, in its sole discretion, limit the aggregate principal amount of
all outstanding General Term Notes as to which exercises of this option (the
"Survivor's Option") will be accepted in any calendar year to one percent (1%)
of the outstanding principal amount of all General Term Notes as of the end of
the most recent fiscal year, but not less than $500,000 in any such calendar
year, or such greater amount as the Company in its sole discretion may determine
for any calendar year, and may limit to $100,000, or such greater amount as the
Company in its sole discretion may determine for any calendar year, the
aggregate principal amount of General Term Notes (or portions thereof) as to
which exercise of the Survivor's Option will be accepted in such calendar year
with respect to any individual deceased owner of beneficial interests in such
General Term Notes.

         [If the General Term Note is not an Original Issue Discount Security,
insert -- If an Event of Default with respect to this General Term Note shall
occur and be continuing, the principal of this General Term 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, Redemption Date, Repayment
Date, Stated Maturity or Maturity of any General Term Note shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of the Indenture or this General Term 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,
Redemption Date or Repayment 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, Repayment Date,
Stated Maturity or Maturity, as the case may be, to such Business Day.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of all Outstanding Securities under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of not less than a majority in principal amount of all Outstanding
Securities affected. The Indenture also contains provisions permitting the
Holders of specified percentages in principal amount of all Outstanding
Securities, on behalf of the Holders of all Outstanding Securities, to waive
compliance by the Company with certain provisions of the Indenture. Any such
consent or waiver by the Holder of this General Term Note shall be conclusive
and binding upon such Holder and upon all future Holders of this General Term
Note and of any General Term Note issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this General Term Note.




                                       23
<PAGE>   24

         The Indenture permits the Holders of not less than a majority in
principal amount of all Outstanding Securities of any series thereunder to waive
on behalf of the Holders of all Outstanding Securities of such series any past
default by the Company, provided that no such waiver may be made with respect to
a default in the payment of the principal of or premium, if any, or the interest
on any Security of such series or the default by the Company 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 General Term 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 General Term Notes shall have made written request, and offered
satisfactory 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 General Term Notes 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 General Term Note on or after the
respective due dates expressed herein.

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

Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new General Term Notes of this series and of like tenor, of authorized

designated transferee or transferees.

         The General Term Notes of this series are issuable only in registered

set forth, General Term Notes of this series are exchangeable for a like
aggregate principal amount of General Term Notes of this series 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 Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         [If this General Term Note is redeemable at the option of the Company,
insert -- The Company shall not be required (i) to issue, register the transfer
of or exchange this General Term Note if this General Term Note may be among
those selected for redemption during a period beginning at the opening of
business 15 days before selection of the General Term Notes to be redeemed under
Section 1103 of the Indenture and ending at the close of business on the day of
the mailing of the relevant notice of redemption, (ii) to register the transfer
of or exchange any General Term Note so selected for redemption in whole or in
part, except, in the case of any General Term Note to be redeemed in part, the
portion thereof not to be

redeemed, or (iii) to issue, register the transfer of or exchange any General
Term Note which has been surrendered for repayment at the option of the Holder,
except the portion, if any, of such General Term Note not to be so repaid.]

         Prior to due presentment of this General Term Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this General Term Note is registered as the

and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary.

defined in the Indenture shall have the meanings assigned to them in the
Indenture.

                                   ARTICLE III

               REDEMPTION OF GENERAL TERM NOTES; CHANGE OF CONTROL

         SECTION 301. Redemption of General Term Notes. (a) Each General Term
Note may be redeemed by the Company in whole or in part if so provided in, and
in accordance with, the terms of such General Term Note issued by the Company.
The Company may redeem any General Term Note which by its terms is redeemable
prior to Stated Maturity without also redeeming any other General Term Note
which is redeemable prior to Stated Maturity.

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

         (1) Within 30 days following the Change in Control Date, the Company
    shall mail a notice (the "Required Repurchase Notice") to each Holder with a
    copy to the Trustee stating:



                                       27

<PAGE>   28

             (i)   that a Change in Control has occurred and that such Holder
         has the right to require the Company to repurchase all or any part of
         such Holder's General Term 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 General
         Term Notes to be repurchased, which shall be consistent with this
         Section and the Indenture.

         (2) Holders electing to have a General Term Note repurchased must
    deliver a written notice (the "Change in Control Purchase Notice") to the
    Paying Agent (initially the Trustee) at its office in The City of New York,
    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
    General Term Notes to be repurchased, which portion must be $1,000 or an
    integral multiple thereof; (ii) that such General Term Notes are to be
    repurchased by the Company pursuant to the change in control provisions of
    the Indenture; and (iii) unless the General Term Notes are represented by
    one or more Global Notes, the certificate numbers of the General Term Notes
    to be delivered by the Holder thereof for repurchase by the Company. 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



                                       28
<PAGE>   29

    principal amount and, if applicable, the certificate numbers of the General
    Term Notes as to which the withdrawal notice relates and the principal
    amount of such General Term Notes, if any, which remains subject to a Change
    in Control Purchase Notice.

         If a General Term Note is represented by a Global Note (as described in
    Article VII below), the Depositary or its nominee will be the Holder of such
    General Term Note and therefore will be the only entity that can elect a
    Required Repurchase of such General Term Note. To obtain repayment pursuant
    to this Section 301(b) with respect to such General Term Note, the
    beneficial owner of such General Term Note must provide to the broker or
    other entity through which it holds the beneficial interest in such General
    Term 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 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 301(b). 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 301(b) to such beneficial owner.

         (3) Payment of the Change of Control Purchase Price for a General Term
    Note for which a Change in Control Purchase Notice has been delivered and
    not withdrawn is conditioned (except in the case of a General Term Note
    represented by one or more Global Notes) upon delivery of such General Term
    Note (together with necessary endorsements) to the Paying Agent at its
    office in The City of New York, or any other office of the Paying Agent
    maintained

                                       29

<PAGE>   30


    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 General Term Note will be
    made promptly following the later of the Purchase Date or the time of
    delivery of such General Term 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 General Term Note on the Business Day
    following the Purchase Date, then, on and after such date, interest will
    cease accruing, and, if applicable, amounts will no longer accrue on any
    such General Term Note that is an Original Issue Discount Security, whether
    or not such General Term Note is delivered to the Paying Agent, 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 General Term
    Note).

         (4) The Company shall comply with the provisions of Rule 13e-4 and any
    other tender offer rules under the Exchange Act, which may then be
    applicable and shall file Schedule 13E-4 or any other schedule required
    thereunder in connection with any offer by the Company to repurchase General
    Term Notes at the option of Holders upon a Change in Control.

         (5) No General Term Note 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 General Term Notes).

                                   ARTICLE IV

                              REPAYMENT UPON DEATH

         If so specified in any General Term Note, the Holder of such General
Term Note will have the option (the "Survivor's Option") to elect repayment of
such General Term Note prior to its Stated Maturity in the event of the death of
the beneficial owner of such General Term Note.




                                       30
<PAGE>   31
               Pursuant to exercise of the Survivor's Option, if applicable, the
Company will repay any General Term Note (or portion thereof) properly tendered
for repayment by or on behalf of the person (the "Representative") that has
authority to act on behalf of the deceased beneficial owner of such General Term
Note under the laws of the appropriate jurisdiction (including, without
limitation, the trustee of a personal trust, the personal representative,
executor, surviving joint tenant or surviving tenant by the entirety of such
deceased beneficial owner) at a price equal to one-hundred percent (100%) of the
principal amount of the beneficial interest of the deceased owner of such
General Term Note plus accrued interest to the date of such payment, subject to
the limitations below. In order for a Holder to exercise the Survivor's Option,
the deceased beneficial owner or his or her Representative must have
individually or collectively held the General Term Note for 120 days. The
Company may, in its sole discretion, limit the aggregate principal amount of
General Term Notes as to which exercises of the Survivor's Option will be
accepted in any calendar year (the "Annual Put Limitation") to one percent (1%)
of the outstanding principal amount of the General Term Notes as of the end of
the most recent fiscal year, but not less than $500,000 in any such calendar
year, or such greater amount as the Company in its sole discretion may determine
for any calendar year, and may limit to $100,000, or such greater amount as the
Company in its sole discretion may determine for any calendar year, the
aggregate principal amount of General Term Notes (or portions thereof) as to
which exercise of the Survivor's Option will be accepted in such calendar year
with respect to any individual deceased owner of beneficial interests in such
General Term Notes (the "Individual Put Limitation"). Moreover, the Company will
not make principal repayments pursuant to exercise of the Survivor's Option in
amounts that are less that $1,000, and, in the event that the limitations
described in the preceding sentence would result in the partial repayment of any
General Term Note, the principal amount of such General Term Note remaining
outstanding after repayment must be at least $1,000 (the minimum authorized
denomination of the General Term Notes). Any General Term Note (or portion
thereof) tendered pursuant





                                       31
<PAGE>   32

to exercise of the Survivor's Option may be withdrawn by a written request of
its Holder received by the Trustee prior to its repayment.



               Each General Term Note (or portion thereof) that is tendered
pursuant to a valid exercise of the Survivor's Option will be accepted promptly
in the order all such General Term Notes are tendered, except for any General
Term Note (or portion thereof) the acceptance of which would contravene (i) the
Annual Put Limitation, if applied, or (ii) the Individual Put Limitation, if
applied, with respect to the relevant individual deceased owner of beneficial
interests therein. If, as of the end of any calendar year, the aggregate
principal amount of General Term Notes (or portions thereof) that have been
accepted pursuant to exercise of the Survivor's Option for such year has not
exceeded the Annual Put Limitation, if applied, for such year, any exercise(s)
of the Survivor's Option with respect to General Term Notes (or portions
thereof) not accepted during such calendar year because such acceptance would
have contravened the Individual Put Limitation, if applied, with respect to an
individual deceased owner of beneficial interests therein will be accepted in
the order all such General Term Notes (or portions thereof) were tendered, to
the extent that any such exercise would not exceed the Annual Put Limitation, if
applied, for such calendar year. Any General Term Note (or portion thereof)
accepted for repayment pursuant to exercise of the Survivor's Option will be
repaid no later than the first Interest Payment Date that occurs 20 or more
calendar days after the date of such acceptance. Each General Term Note (or any
portion thereof) tendered for repayment that is not accepted in any calendar
year because of the application of the Annual Put Limitation will be deemed to
be tendered in the following calendar year in the order in which all such
General Term Notes (or portions thereof) were originally tendered, unless any
such General Term Note (or portion thereof) is withdrawn by the Representative
for the deceased owner prior to its repayment. In the event that a General Term
Note (or any portion thereof) tendered for repayment pursuant to valid exercise
of the Survivor's Option is not accepted, the Trustee will deliver a notice by
first-class mail to the registered Holder thereof at its last known address as
indicated in the



                                       32
<PAGE>   33

Security Register or, alternatively to the applicable Representative that states
the reasons such General Term Note (or portion thereof) has not been accepted
for repayment.


               Subject to the foregoing, in order for a Survivor's Option to be
validly exercised with respect to any General Term Note (or portion thereof),
the Trustee must receive from the Representative of the individual deceased
owner of beneficial interests therein (i) a written request for payment signed
by the Representative, 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, (ii) if any such General Term Note is not
represented by a Global Note (as described in Article VII below), tender of the
General Term Note (or portion thereof) to be repaid, (iii) appropriate evidence
satisfactory to the Company and the Trustee that (A) the Representative has
authority to act on behalf of the individual deceased beneficial owner, (B) the
death of such beneficial owner has occurred and (C) the deceased individual was
the owner of a beneficial interest in such General Term Note at the time of
death, (iv) if applicable, a properly executed assignment or endorsement, and
(v) if the beneficial interest in such General Term Note is held by a nominee of
the deceased beneficial owner, a certificate satisfactory to the Trustee from
such nominee attesting to the deceased's ownership of a beneficial interest in
such General Term Note. All questions as to the eligibility or validity of any
exercise of the Survivor's Option will be determined by the Company, in its sole
discretion, which determinations will be final and binding on all parties.


               If a General Term Note is represented by a Global Note (as
described in Article VII below), the Depositary or its nominee will be the
Holder of such General Term Note and therefore will be the only entity that can
exercise the Survivor's Option for such General Term Note. To obtain repayment
pursuant to exercise of the Survivor's Option with respect to such General Term
Note, the


                                       33
<PAGE>   34

Representative must provide to the broker or other entity through which the
beneficial interest in such General Term Note is held by the deceased owner (i)
the documents described in clauses (i) and (iii) of the preceding paragraph and
(ii) instructions to such broker or other entity to notify the Depositary of
such Representative's desire to obtain repayment pursuant to exercise of the
Survivor's Option. Such broker or other entity shall provide to the Trustee (i)
the documents received from the Representative referred to in clause (i) of the
preceding sentence and (ii) a certificate satisfactory to the Trustee from such
broker or other entity stating that it represents the deceased beneficial owner
and that such deceased beneficial owner or such deceased beneficial owner's
Representative individually or collectively held such General Term Note for at
lease 120 days. Such broker or other entity will be responsible for disbursing
any payments it receives pursuant to exercise of the Survivor's Option to the
appropriate Representative.

                                    ARTICLE V

brief certificate from the principal executive officer, principal financial
officer or principal accounting officer as to his or her knowledge of the
Company's compliance with all conditions and covenants under this Sixth
Supplemental Indenture. For such purposes, such compliance shall be determined
without regard to any period of grace or requirement of notice provided
hereunder and, if the Company shall be in default, specifying all such defaults
and the nature and status thereof of which they may have knowledge.


               (b) The Company shall deliver to the Trustee, as soon as possible
and in any event within 10 days after the Company becomes aware of the
occurrence of an




                                       34
<PAGE>   35

Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default, an Officers' Certificate setting forth the
details of such Event of Default or default, and the action which the Company
proposes to take with respect thereto.

               SECTION 502. Existence. So long as any of the General Term Notes
are Outstanding, subject to Article 8 of the Indenture, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence and all rights (charter and statutory) and

disadvantageous in any material respect to the Holders of the General Term
Notes.

               SECTION 503. Maintenance of Properties. So long as any of the
General Term Notes are Outstanding, the Company will cause all properties used

betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business and not
disadvantageous in any material respect to the Holders.


               SECTION 504. Payment of Taxes and Other Claims. So long as any of
the General Term Notes are Outstanding, the Company will pay or discharge or
cause to be paid or discharged, before the same shall become delinquent, (1) all
taxes, assessments and governmental charges levied or imposed upon the Company
or any Subsidiary or upon the income, profits or property of the Company or any
Subsidiary, and (2) all lawful claims for labor, materials and supplies which,




                                       35
<PAGE>   36

if unpaid, might by law become a Lien upon the property of the Company or any
Subsidiary; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim the amount of which, applicability or validity is being contested in good
faith by appropriate proceedings.

               SECTION 505. Insurance. So long as any of the General Term Notes
are Outstanding, the Company shall, and each of its Restricted Subsidiaries and
Consumers shall, keep insured by financially sound and reputable insurers all
property of a character usually insured by entities engaged in the same or
similar businesses similarly situated against loss or damage of the kinds and in
the amounts customarily insured against by such entities and carry such amounts
of other insurance as is usually carried by such entities.

               SECTION 506. Compliance with Laws. So long as any of the General
Term Notes are Outstanding, the Company shall, and each of its Restricted
Subsidiaries and Consumers shall, comply in all material respects with all laws
applicable to the Company or such Restricted Subsidiary or Consumers, as the
case may be, its respective business and properties.

               SECTION 508. Limitation on Certain Liens. (a) So long as any of
the General Term Notes are outstanding, the Company 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 Company or any Subsidiary
a preferential interest (hereinafter in this Section referred to as a "Lien")
upon or with respect to the Capital Stock of Consumers, Enterprises or CMS Oil &
Gas Co. without making effective provision whereby the General Term 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:



                                       36
<PAGE>   37

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
Company 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 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 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 of the secured Indebtedness of the Company
at such date shall not exceed 10% of Consolidated Assets at such date.

               SECTION 509. Limitation on Consolidation, Merger, Sale or
Conveyance. In addition to the limitations set forth in Article 8 of the
Indenture, so long as the General Term Notes are Outstanding and until the
General Term 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 Company shall be permanently released from the following
provisions, 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

               SECTION 510. Limitation on Consolidated Indebtedness. (a) So long
as any of the General Term Notes are Outstanding and until the General Term
Notes are rated BBB- or above (or an equivalent rating) by Standard & Poor's and

an equivalent of such rating then employed by such organization) at which time
the Company shall be permanently released from the provision of this Section
510, the Company shall not, and shall not permit any Restricted Subsidiary of
the Company to, issue, create, assume, guarantee, incur or otherwise become
liable for (collectively, "issue"), directly or indirectly, any Indebtedness
unless (i) the Consolidated Coverage Ratio of the Company 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 Company 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

<PAGE>   39

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 Company 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 1.6 to 1.0 and (ii), immediately after giving effect to the issuance of
such Indebtedness and (if applicable) the application of the net proceeds
thereof to refinance other Indebtedness, the Consolidated Leverage Ratio is
equal to or less than a ratio of 0.75 to 1.0.

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

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

          (1) of this Subsection) outstanding on the date of the original
          Indenture, as set forth on Schedule 510(b)(2) attached hereto and made
          a part hereof, and 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 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

<PAGE>   40

          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, (B)
          shall have an Average Life equal to or greater than the remaining
          Average Life of the Indebtedness so exchanged, refunded or refinanced
          and (C) if the Indebtedness to be exchanged, refunded or refinanced is
          subordinated to the General Term Notes, the Indebtedness is
          subordinated to the General Term Notes in right of payment;


               (3)  Indebtedness of the Company owed to and held by a Subsidiary
          and Indebtedness of a Subsidiary owed to and held by the Company;
          provided, however, that, in the case of Indebtedness of the Company
          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 Company or a Subsidiary) shall be deemed for the
          purposes of this Subsection to constitute the issuance of such
          Indebtedness by the Company;

               (4)  Indebtedness of the Company issued in exchange for, or the
          proceeds of which are used to refund or refinance, Indebtedness of the
          Company issued in accordance with Subsection (a) of this Section,
          provided that (i) the principal amount (or accreted value in the case
          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, (B) shall have an Average Life equal to or
          greater than the remaining Average Life of the Indebtedness so
          exchanged, refunded or refinanced and (C) if the Indebtedness to be
          exchanged, refunded

<PAGE>   41

          or refinanced is subordinated to the General Term Notes, the
          Indebtedness so issued is subordinated to the General Term Notes in
          right of payment; and

               (5)  Indebtedness of a Restricted Subsidiary issued in exchange
          for, or the proceeds of which are used to refund or refinance,
          Indebtedness of a Restricted Subsidiary issued in accordance with
          Subsection (a) of this Section, provided that (i) the principal amount
          (or accreted value in the case 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.

               SECTION 511. Limitation on Restricted Payments. (a) So long as
the General Term Notes are Outstanding and until the General Term 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
Company shall be permanently released from the provision of this Section 511,
the Company shall not, and shall not permit any Restricted Subsidiary of the
Company, 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 the Capital Stock of the Company (except dividends or distributions
payable solely in Non-Convertible Capital Stock of the Company 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 (any such dividend, distribution, purchase, redemption, other
acquisition or retirement being hereinafter referred to



                                       41
<PAGE>   42

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 September 30, 1993, would exceed
          the sum of:

               (A)  $120,000,000;

               (B)  100% of Consolidated Net Income, accrued during the period
          (treated as one accounting period) from September 30, 1993 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 Proceeds received by the Company from the
          issue or sale of or contribution with respect to its Capital Stock
          subsequent to September 30, 1993.

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 511(a) shall not prohibit:



                                       42
<PAGE>   43

                    (i)   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); 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 Company's Capital Stock issued in respect of the
               acquisition of any business or assets by the Company 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 512. Limitation on Transactions with Affiliates. So long
as any of the General Term Notes are Outstanding, the Company shall not directly
or indirectly, conduct any business or enter into any transaction or series of
related transactions (including the purchase, sale, lease or exchange of any
property or the rendering of any service) with an Affiliate unless the terms of
such business, transaction or series of transactions are as favorable to the
Company as terms that could be obtainable at the time for a comparable
transaction or series of related




                                       43

transactions in arm's-length dealings with an unrelated third Person. This
Section shall not apply to (x) compensation paid to officers and directors of
the Company which has been approved by the Board of Directors of the Company or
(y) loans to the Company or an Affiliate pursuant to a global cash management
program, which loans mature within one year from the date thereof.

                                   ARTICLE VI

                          ADDITIONAL EVENTS OF DEFAULT
                     WITH RESPECT TO THE GENERAL TERM NOTES

               SECTION 601. Definition. All of the events specified in Section
501 of the Indenture and the events specified in Section 602 of this Article
shall be "Events of Default" with respect to the General Term Notes.

(whatever the reason for such Event of Default and whether or not it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body) shall be an Event of Default with respect
to the General Term Notes for all purposes of the Indenture:

               (a) a default or event of default in respect of any Indebtedness
of the Company having an aggregate outstanding principal amount at the time of
such default in excess of $25,000,000 shall occur which results in the
acceleration of such Indebtedness or Indebtedness of the Company having an

               (b) the entry of a final judgment or judgments against the
Company aggregating in excess of $25,000,000 which remain undischarged or

                                   ARTICLE VII

                                  GLOBAL NOTES


               The General Term Notes will be issued initially in the form of
Global Notes. "Global Note" means a registered General Term Note evidencing one
or more General Term Notes issued to a depositary (the "Depositary") or its
nominee, in accordance with this Article and bearing the legend prescribed in
this Article. A single Global Note will represent all General Term Notes issued
on the same date and having the same terms, including, but not limited to, the
same Interest Payment Dates, rate of interest, Stated Maturity, and redemption
provisions (if any). The Company shall execute and the Trustee shall, in
accordance with this Article and the Company Order with respect to the General
Term 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 General Term 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 this Global Note is presented by
an authorized representative of the Depositary to the Company or its agent for
registration of transfer, exchange or payment, and any Note issued is registered
in the name of the Depositary or in such other name as is requested by the
Depositary, any transfer, pledge or other use hereof for value or otherwise by
or to any person shall be wrongful inasmuch as the registered owner hereof, the
Depositary, has an interest herein."



                                       45
<PAGE>   46

               Notwithstanding Section 305 of the Indenture, unless and until it
is exchanged in whole or in part for General Term Notes in definitive form, a
Global Note representing one or more General Term 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 Depositary or any such nominee to a successor Depositary
for General Term Notes or a nominee of such successor Depositary.

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

               The Company may at any time and in its sole discretion determine
that the General Term 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 Company
will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive General Term Notes, will authenticate
and deliver General Term Notes in definitive form in an aggregate principal
amount equal to the principal amount of the Global Note or Notes representing
such General Term Notes in exchange for such Global Note or Notes.

<PAGE>   47

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

                  (i)  to each Person specified by such Depositary a new General
               Term 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
               General Term Notes in definitive form delivered to Holders
               thereof.

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

               Upon the exchange of a Global Note for General Term Notes in
definitive form, such Global Note shall be canceled by the Trustee. General Term
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 General Term Notes to the persons in
whose names such General Term Notes are so registered.

                                   DEFEASANCE


               All of the provisions of Article Fourteen of the Original
Indenture shall be applicable to the General Term Notes. Upon satisfaction by
the Company of the requirements of Section 1404 of the Indenture, in connection

Company shall be released from its obligations under Article Eight of the
Original Indenture and under Articles III and V of this Sixth Supplemental
Indenture with respect to the General Term Notes.

                                   ARTICLE IX

                             SUPPLEMENTAL INDENTURES

               This Sixth Supplemental Indenture is a supplement to the Original
Indenture. As supplemented by this Sixth Supplemental Indenture, the Original
Indenture is in all respects ratified, approved and confirmed, and the Original
Indenture and this Sixth Supplemental Indenture shall together constitute one
and the same instrument.

               The Company may, by supplemental indenture, amend this Sixth
Supplemental Indenture to provide for additional definitions, terms and
provisions relating to General Term Notes. Any such supplemental indenture shall
not adversely affect the rights and privileges of Holders of General Term Notes
issued prior to such supplemental indenture. Any such supplemental indenture may
include, but is not limited to including, additional provisions permitting
payment of General Term Notes prior to Stated Maturity at the option of the
Holders, issuance of General Term Notes in currencies other than Dollars, and
special provisions relating to interest rate provisions.
