         SECTION 2.04. Form of Reverse of 2023 Note.

         This 3.375% Convertible Senior Note due 2023 is one of a duly
authorized issue of securities of the Issuer (herein called the "2023 Notes"),
issued and to be issued under an Indenture, dated as of September 15, 1992, as
supplemented by certain supplemental indentures, including the Thirteenth
Supplemental Indenture, dated as of July 16, 2003 (herein collectively referred
to as the "Indenture"), between the Issuer and Bank One Trust Company, N.A., a
national banking association (successor to 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, and the
Holders of the 2023 Notes and of the terms upon which the 2023 Notes are, and
are to be, authenticated and delivered. This 2023 Note is one of the series
designated on the face hereof, issued in an initial aggregate principal amount
of $150,000,000 (except that such amount shall be increased to an amount up to
$200,000,000 to the extent of any exercise by the Initial Purchasers of their
option to purchase additional 2023 Notes). Additional Securities, without
limitation as to amount, having substantially the same terms as the 2023 Notes
(except a different issue date, issue price and bearing interest from the last
Interest Payment Date to which interest has been paid or duly provided for on
the 2023 Notes, and, if no interest has been paid, from July 16, 2003), may also
be issued by the Issuer pursuant to the Indenture without the consent of the
existing Holders of the 2023 Notes. Such additional Securities shall be part of
the same series as the 2023 Notes.

         Holders of 2023 Notes at the close of business on a Record Date will
receive payment of interest, payable on the corresponding Interest Payment Date
notwithstanding the conversion of such 2023 Notes at any time after the close of
business on such Record Date. 2023 Notes surrendered for conversion by a Holder
during the period from the close of business on any Record Date to the opening
of business on the immediately following Interest Payment Date must be
accompanied by payment of an amount equal to the interest that the Holder is to
receive

                                       18
<PAGE>

on the 2023 Notes; provided, however, that no such payment need be made if (1)
the Issuer has specified a redemption date that is after a Record Date and on or
prior to the immediately following Interest Payment Date, (2) the Issuer has
specified a Purchase Date following a Fundamental Change that is during such
period or (3) any overdue interest exists at the time of conversion with respect
to such 2023 Notes to the extent of such overdue interest. The Holders of the
2023 Notes and any Common Stock issuable upon conversion thereof will continue
to be entitled to receive Additional Amounts in accordance with the Registration
Rights Agreement.

         If the principal hereof or any portion of such principal is not paid
when due (whether upon acceleration, upon the date set for payment of the
Redemption Price, upon the date set for payment of a Purchase Price or
Fundamental Change Purchase Price or upon the Stated Maturity of this 2023 Note)
or if interest due hereon or any portion of such interest is not paid when due
in accordance with the terms of this 2023 Note, then in each such case the
overdue amount shall bear interest at the rate of 3.375% per annum, compounded
semiannually (to the extent that the payment of such interest shall be legally
enforceable), which interest shall accrue from the date such overdue amount was
due to the date payment of such amount, including interest thereon, has been
made or duly provided for, all such interest shall be payable on demand.

         The interest rate borne by the Registrable Securities will be increased
by 0.25% per annum upon the occurrence of a Registration Default, which rate
will increase by an additional 0.25% per annum if such Registration Default has
not been cured within 90 days after the occurrence thereof and will continue to
increase by 0.25% at the beginning of each subsequent 90-day period until all
Registration Defaults have been cured ("Additional Amounts"); provided, that the
aggregate amount of any such increase in the interest rate on the Registrable
Securities shall in no event exceed 0.50% per annum. All accrued Additional
Amounts shall be paid to Holders of Registrable Securities in the same manner
and at the same time as regular payments of interest on the Registrable
Securities. Following the cure of all Registration Defaults, the accrual of
Additional Amounts shall cease and the interest rate on the Registrable
Securities will revert to 3.375% per annum.

         In the event of redemption of this 2023 Note in part only, a new 2023
Note for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof. No sinking fund is provided for the 2023
Notes. The 2023 Notes are redeemable for cash or check in whole, or in part, at
any time on or after July 15, 2008 at the option of the Issuer at a redemption
price ("Redemption Price") equal to 100% of the principal amount of the 2023
Notes to be redeemed plus any accrued and unpaid interest (including Additional
Amounts, if any) to the redemption date. Notice of redemption at the option of
the Issuer shall be mailed at least 30 days but not more than 60 days before a
redemption date to the Trustee, the Paying Agent and each Holder of 2023 Notes
to be redeemed at the Holder's registered address. If money sufficient to pay
the Redemption Price of all 2023 Notes (or portions thereof) to be redeemed on
the redemption date is deposited with the Paying Agent prior to or on the
redemption date, on and after the redemption date interest (including Additional
Amounts, if any), if any, shall cease to accrue on such 2023 Notes or portions
thereof. 2023 Notes in denominations larger than $1,000 principal amount may be
redeemed in part but only in integral multiples of $1,000 principal amount.

                                       19
<PAGE>

         Subject to the terms and conditions of the Indenture, a Holder shall
have the option to require the Issuer to purchase the 2023 Notes held by such
Holder on July 15, 2008, July 15, 2013 and July 15, 2018 (each, a "Purchase
Date") at a purchase price (the "Purchase Price") equal to 100% of the principal
amount of the 2023 Notes to be purchased plus any accrued and unpaid interest
(including Additional Amounts, if any) to but excluding such Purchase Date, upon
delivery of a Purchase Notice containing the information set forth in the
Indenture, from the opening of business on the date that is 20 Business Days
prior to such Purchase Date until the close of business on the fifth Business
Day prior to such Purchase Date and upon delivery of the 2023 Notes to the
Paying Agent by the Holder as set forth in the Indenture. The Issuer will pay
the Purchase Price in cash or by check. 2023 Notes in denominations larger than
$1,000 principal amount may be purchased in part, but only in integral multiples
of $1,000 principal amount.

         If a Fundamental Change shall occur at any time prior to July 15, 2008,
each Holder shall have the right, at such Holder's option and subject to the
terms and conditions of the Indenture, to require the Issuer to purchase any or
all of such Holder's 2023 Notes or any portion of the principal amount thereof
that is equal to $1,000 or an integral multiple of $1,000 on the day that is no
earlier than 60 days nor later than 90 days after the date of the Issuer Notice
of the occurrence of the Fundamental Change (subject to extension to comply with
applicable law) for a Fundamental Change Purchase Price equal to 100% of the
principal amount of 2023 Notes purchased plus accrued and unpaid interest
(including Additional Amounts, if any) to the Fundamental Change Purchase Date,
which Fundamental Change Purchase Price shall be paid by the Issuer in cash or
by check, as set forth in the Indenture.

         Holders have the right to withdraw any Purchase Notice or Fundamental
Change Purchase Notice, as the case may be, by delivery to the Paying Agent of a
written notice of withdrawal in accordance with the provisions of the Indenture.

         If cash sufficient to pay a Fundamental Change Purchase Price or
Purchase Price, as the case may be, of all 2023 Notes or portions thereof to be
purchased as of the Purchase Date or the Fundamental Change Purchase Date, as
the case may be, is on deposit with the Paying Agent on the Business Day
following the Purchase Date or the Fundamental Change Purchase Date, as the case
may be, interest (including Additional Amounts, if any) shall cease to accrue on
such 2023 Notes (or portions thereof) on and after such date, and the Holder
thereof shall have no other rights as such (other than the right to receive the
Purchase Price or Fundamental Change Purchase Price, as the case may be, upon
surrender of such Note).

         Subject to the procedures set forth in the Indenture, a Holder may
convert 2023 Notes into Common Stock on or before the close of business on July
15, 2023 during the periods and upon satisfaction of at least one of the
conditions set forth below:

         (a)      in any calendar quarter (and only during such calendar
         quarter) if the Last Reported Sale Price for Common Stock for at least
         20 Trading Days during the period of 30 consecutive Trading Days ending
         on the last Trading Day of the previous calendar quarter is greater
         than or equal to 120% of the Conversion Price per share of Common Stock
         on such last Trading Day;

                                       20
<PAGE>

         (b)      prior to Maturity during the five Business Days immediately
         following any ten consecutive Trading Day period in which the Trading
         Price per $1,000 principal amount of 2023 Notes (as determined
         following a request by a Holder of the 2023 Notes in accordance with
         the procedures described in the Indenture) for each day of that period
         was less than 95% of the product of the sale price of Common Stock and
         the then applicable Conversion Rate (the "Trading Exception");
         provided, however, that a Holder may not convert its 2023 Notes if the
         average closing sale price of Common Stock for such ten consecutive
         Trading Day period is between the then current Conversion Price and
         120% of the then applicable Conversion Price; in connection with any
         conversion upon satisfaction of such Trading Price condition, the
         Trustee shall have no obligation to determine the Trading Price unless
         the Issuer has requested such determination; and the Issuer shall have
         no obligation to make such request unless the Holder provides
         reasonable evidence that the Trading Price would be less than 95% of
         the product of the sale price of Common Stock and the then applicable
         Conversion Rate; at which time, the Issuer shall instruct the Trustee
         to determine the Trading Price beginning on the next Trading Day and on
         each successive Trading Day until the Trading Price is greater than or
         equal to 95% of the product of the sale price of Common Stock and the
         then applicable Conversion Rate;

         (c)      in the event that the Issuer calls the 2023 Notes for
         redemption, at any time prior to the close of business on the second
         Business Day immediately preceding the redemption date;

         (d)      the Issuer becomes a party to a consolidation, merger or
         binding share exchange pursuant to which the Common Stock would be
         converted into cash or property (other than securities), in which case
         a Holder may surrender 2023 Notes for conversion at any time from and
         after the date which is 15 days prior to the anticipated effective date
         for the transaction until 15 days after the actual effective date of
         such transaction; or

         (e)      the Issuer elects to (i) distribute to all holders of Common
         Stock assets, debt securities or rights to purchase securities of the
         Issuer, which distribution has a per share value as determined by the
         Board of Directors exceeding 15% of the Last Reported Sale Price of a
         share of Common Stock on the Trading Day immediately preceding the
         declaration date for such distribution, or (ii) distribute to all
         holders of Common Stock rights entitling them to purchase, for a period
         expiring within 60 days after the date of such distribution, shares of
         Common Stock at less than the Last Reported Sale Price of Common Stock
         on the Trading Day immediately preceding the declaration date of the
         distribution. In the case of the foregoing clauses (i) and (ii), the
         Issuer must notify the Holders at least 20 Business Days immediately
         prior to the ex date for such distribution. Once the Issuer has given
         such notice, Holders may surrender their 2023 Notes for conversion at
         any time thereafter until the earlier of the close of business on the
         Business Day immediately prior to the ex date or the Issuer's
         announcement that such distribution will not take place; provided,
         however, that a Holder may not exercise this right to convert if the
         Holder may participate in the distribution without conversion. As used
         herein, the term "ex date," when used with respect to any issuance or
         distribution, shall

                                       21
<PAGE>

         mean the first date on which the Common Stock trades regular way on
         such exchange or in such market without the right to receive such
         issuance or distribution.

         If the Issuer engages in certain reclassifications of its Common Stock
or is a party to a consolidation, merger, binding share exchange or transfer of
all or substantially all of its assets pursuant to which Common Stock is
converted into cash, securities or other property, then, at the effective time
of the transaction, the right to convert a 2023 Note into Common Stock will be
changed into a right to convert a 2023 Note into the kind and amount of cash,
securities or other property which the Holder would have received if the Holder
had converted its 2023 Notes immediately prior to the transaction. If the Issuer
engages in any transaction described in the preceding sentence, the Conversion
Rate will not be adjusted. If the transaction also constitutes a Fundamental
Change, a Holder can require the Issuer to purchase all or a portion of its 2023
Notes as described in the Indenture.

         2023 Notes in respect of which a Holder has delivered a notice of
exercise of the option to require the Issuer to purchase such 2023 Notes
pursuant to Article VII or Article XIII of the Indenture may be converted only
if the notice of exercise is withdrawn in accordance with the terms of the
Indenture.

         The initial Conversion Rate is 93.7137 shares of Common Stock per
$1,000 principal amount, subject to adjustment in certain events described in
the Indenture. The Issuer shall deliver cash or a check in lieu of any
fractional share of Common Stock.

         Holders of 2023 Notes at the close of business on a Record Date will
receive payment of interest, payable on the corresponding Interest Payment Date
notwithstanding the conversion of such 2023 Notes at any time after the close of
business on such Record Date. 2023 Notes surrendered for conversion by a Holder
during the period from the close of business on any Record Date to the opening
of business on the immediately following Interest Payment Date must be
accompanied by payment of an amount equal to the interest that the Holder is to
receive on the 2023 Notes; provided, however, that no such payment need be made
if (1) the Issuer has specified a redemption date that is after a Record Date
and on or prior to the immediately following Interest Payment Date, (2) the
Issuer has specified a Purchase Date following a Fundamental Change that is
during such period or (3) any overdue interest exists at the time of conversion
with respect to such 2023 Notes to the extent of such overdue interest. The
Holders of the 2023 Notes and any Common Stock issuable upon conversion thereof
will continue to be entitled to receive Additional Amounts in accordance with
the Registration Rights Agreement.

         To convert the 2023 Notes a Holder must (i) complete and manually sign
the irrevocable conversion notice on the back of the 2023 Notes (or complete and
manually sign a facsimile of such notice) and deliver such notice to the
Conversion Agent at the office maintained by the Conversion Agent for such
purpose, (ii) surrender the 2023 Notes to the Conversion Agent, (iii) furnish
appropriate endorsements and transfer documents if required by the Conversion
Agent, the Issuer or the Trustee and (iv) pay any transfer or similar tax, if
required.

         A Holder may convert a portion of the 2023 Notes only if the principal
amount of such portion is $1,000 or a multiple of $1,000. No payment or
adjustment shall be made for dividends

                                       22
<PAGE>

on the Common Stock except as provided in the Indenture. On conversion of the
2023 Notes, that portion of accrued and unpaid interest attributable to the
period from the Original Issue Date to the Conversion Date shall be deemed
canceled, extinguished or forfeited rather than paid in full to the Holder
thereof through the delivery of the Common Stock (together with any cash payment
in lieu of fractional shares) in exchange for the portion of the 2023 Notes
being converted pursuant to the terms hereof; and the Fair Market Value of such
shares of Common Stock (together with any such cash payment in lieu of
fractional shares) shall be treated as issued, to the extent thereof, first in
exchange for interest accrued and unpaid through the Conversion Date, and the
balance, if any, of such Fair Market Value of such Common Stock (and any such
cash payment) shall be treated as issued in exchange for the principal amount of
the 2023 Notes being converted pursuant to the provisions hereof.
Notwithstanding the conversion of any 2023 Notes, the Holders of the 2023 Notes
and any Common Stock issuable upon conversion thereof will continue to be
entitled to receive Additional Amounts in accordance with the Registration
Rights Agreement.

         If an Event of Default with respect to this 2023 Note shall occur and
be continuing, the principal of this 2023 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,
repurchase date, Stated Maturity or Maturity of any 2023 Note shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of the Indenture or this 2023 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 Trustee and the Paying Agent shall return to the Issuer upon
written request any money or property held by them for the payment of any amount
with respect to the 2023 Notes that remains unclaimed for two years, provided,
however, that the Trustee or such Paying Agent, before being required to make
any such return, shall at the expense of the Issuer cause to be published once
in a newspaper of general circulation in The City of New York or mail to each
such Holder notice that such money or property remains unclaimed and that, after
a date specified therein, which shall not be less than 30 days from the date of
such publication or mailing, any unclaimed money or property then remaining
shall be returned to the Issuer. After return to the Issuer, Holders entitled to
the money or property must look to the Issuer for payment as general creditors
unless an applicable abandoned property law designates another Person.

         The Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this 2023 Note or (ii) certain restrictive covenants and
Events of Default with respect to this 2023 Note, in each case upon compliance
with certain conditions set forth therein.

                                       23
<PAGE>

         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 2023 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 2023 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 enforcement of payment of the principal of (and premium, if any)
or any interest on this 2023 Note on or after the respective due dates expressed
herein.

         No reference herein to the Indenture and no provision of this 2023 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 2023 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 2023 Note is registrable in the Security
Register, upon surrender of this 2023 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 2023 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 2023 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 2023 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

                                       24
<PAGE>

limitations therein set forth, 2023 Notes are exchangeable for a like aggregate
principal amount of 2023 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.

         In the event of any redemption or purchase in part, the Issuer shall
not be required to (i) issue, exchange or register the transfer of this 2023
Note for a period of 15 days next preceding the mailing of the notice of
redemption of 2023 Notes or (ii) exchange or register the transfer of any 2023
Note or any portion thereof selected, called or being called for redemption,
except in the case of any 2023 Note to be redeemed in part, the portion thereof
not so to be redeemed.

         Prior to due presentment of this 2023 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 2023 Note is registered as the owner hereof
for all purposes, whether or not this 2023 Note be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

         The Issuer will be responsible for making all calculations called for
under the 2023 Notes. These calculations include, but are not limited to,
determination of the market prices for the Common Stock, accrued interest
payable on the 2023 Notes and Conversion Price of the 2023 Notes. The Issuer
will make these calculations in good faith and, absent manifest error, these
calculations will be final and binding on the Holders. The Issuer will provide
to each of the Trustee and the Conversion Agent a schedule of its calculations,
and each of the Trustee and the Conversion Agent is entitled to rely upon the
accuracy of such calculations without independent verification. The Trustee will
forward the Issuer's calculations to any Holder upon the request of such Holder.

         All terms used in this 2023 Note without definition which are defined
in the Indenture shall have the meanings assigned to them in the Indenture.

                            FORM OF CONVERSION NOTICE

To: CMS Energy Corporation

         The undersigned registered holder of this 2023 Note hereby exercises

principal amount or an integral multiple thereof) designated below, for shares
of Common Stock of CMS Energy Corporation in accordance with the terms of the
Indenture referred to in this 2023 Note, and directs that the shares, if any,
issuable and deliverable upon such conversion, together with any check for cash

<PAGE>

                                   ARTICLE III

                       PURCHASE UPON A FUNDAMENTAL CHANGE

     SECTION 3.01. Purchase at the Option of the Holder Upon a Fundamental
Change. If a Fundamental Change shall occur at any time prior to July 15, 2008,
each Holder shall have the right, at such Holder's option, to require the Issuer
to purchase any or all of such Holder's 2023 Notes for cash or a check on the
date that is no earlier than 60 days nor later than 90 days after the date of
the Issuer Notice of the occurrence of such Fundamental Change (subject to
extension to comply with applicable law, as provided in Section 5.04) (the
"Fundamental Change Purchase Date"). The 2023 Notes shall be repurchased in
integral multiples of $1,000 of the principal amount. The Issuer shall purchase
such 2023 Notes at a price (the "Fundamental Change Purchase Price") equal to
100% of the principal amount of the Notes to be purchased plus accrued and
unpaid interest, including Additional Amounts, if any, to the Fundamental Change
Purchase Date. No 2023 Notes may be purchased at the option of the Holders upon
a Fundamental Change if there has occurred and is continuing an Event of Default
(other than an Event of Default that is cured by the payment of the Fundamental
Change Purchase Price of the 2023 Notes).

         SECTION 3.02. Notice of Fundamental Change. The Issuer, or at its
request (which must be received by the Paying Agent at least three Business Days
(or such lesser period as agreed to by the Paying Agent) prior to the date the
Paying Agent is requested to give such notice as described below), the Paying
Agent, in the name of and at the expense of the Issuer, shall mail to all
Holders and the Trustee and the Paying Agent an Issuer Notice of the occurrence
of a Fundamental Change and of the purchase right arising as a result thereof,
including the information required by Section 5.01 hereof, on or before the 30th
day after the occurrence of such Fundamental Change.

         SECTION 3.03. Exercise of Option. For a 2023 Note to be so purchased at
the option of the Holder, the Paying Agent must receive such 2023 Note duly
endorsed for transfer, together with a written notice of purchase in the form
attached hereto as Exhibit A (a "Fundamental Change Purchase Notice") and the
form entitled "Form of Fundamental Change Purchase Notice" on the reverse
thereof duly completed, on or before the 30th day prior to the occurrence of
such Fundamental Change, subject to extension to comply with applicable law. The
Fundamental Change Purchase Notice shall state:

         (a)      if certificated, the certificate numbers of the 2023 Notes
         which the Holder shall deliver to be purchased, or, if not
         certificated, the Fundamental Change Purchase Notice must comply with
         appropriate Depositary procedures;

         (b)      the portion of the principal amount of the 2023 Notes which
         the Holder shall deliver to be purchased, which portion must be $1,000
         in principal amount or an integral multiple thereof; and

                                       27
<PAGE>

         (c)      that such 2023 Notes shall be purchased as of the Fundamental
         Change Purchase Date pursuant to the terms and conditions specified in
         the 2023 Notes and in this Thirteenth Supplemental Indenture.

         SECTION 3.04. Procedures. The Issuer shall purchase from a Holder,
pursuant to this Article III, 2023 Notes if the principal amount of such 2023
Notes is $1,000 or a multiple of $1,000 if so requested by such Holder.

         Any purchase by the Issuer contemplated pursuant to the provisions of
this Article III shall be consummated by the delivery of the Fundamental Change
Purchase Price to be received by the Holder promptly following the later of the
Fundamental Change Purchase Date or the time of book-entry transfer or delivery
of the 2023 Notes.

         Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Fundamental Change Purchase Notice contemplated by
Section 3.03 hereof shall have the right at any time prior to the close of
business on the Business Day prior to the Fundamental Change Purchase Date to
withdraw such Fundamental Change Purchase Notice (in whole or in part) by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 5.02 hereof.

         The Paying Agent shall promptly notify the Issuer of the receipt by it
of any Fundamental Change Purchase Notice or written notice of withdrawal
thereof.

         On or before 10:00 a.m. (New York City time) on the Fundamental Change
Purchase Date, the Issuer shall deposit with the Paying Agent (or if the Issuer
or an Affiliate of the Issuer is acting as the Paying Agent, shall segregate and
hold in trust) money sufficient to pay the aggregate Fundamental Change Purchase
Price of the 2023 Notes to be purchased pursuant to this Article III. Payment by
the Paying Agent of the Fundamental Change Purchase Price for such 2023 Notes
shall be made promptly following the later of the Fundamental Change Purchase
Date or the time of book-entry transfer or delivery of such 2023 Notes. If the
Paying Agent holds, in accordance with the terms of the Indenture, money
sufficient to pay the Fundamental Change Purchase Price of such 2023 Notes on
the Business Day following the Fundamental Change Purchase Date, then, on and
after such date, such 2023 Notes shall cease to be outstanding and interest
(including Additional Amounts, if any) on such 2023 Notes shall cease to accrue,
whether or not book-entry transfer of such 2023 Notes is made or such 2023 Notes
are delivered to the Paying Agent, and all other rights of the Holder shall
terminate (other than the right to receive the Fundamental Change Purchase Price
upon delivery or transfer of the 2023 Notes). Nothing herein shall preclude any
withholding tax required by law.

         The Issuer shall require each Paying Agent (other than the Trustee) to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of the
Fundamental Change Purchase Price and shall notify the Trustee of any default by
the Issuer in making any such payment. If the Issuer or an Affiliate of the
Issuer acts as Paying Agent, it shall segregate the money held by it as Paying
Agent and hold it as a separate trust fund. The Issuer at any time may require a
Paying Agent to deliver all money held by it to the Trustee and to account for
any funds disbursed by the Paying Agent.

                                       28
<PAGE>

Upon doing so, the Paying Agent shall have no further liability for the cash
delivered to the Trustee.

         All questions as to the validity, eligibility (including time of
receipt) and acceptance of any 2023 Notes for redemption shall be determined by
the Issuer, whose determination shall be final and binding.

                                   ARTICLE IV

                                OPTIONAL PURCHASE

Holder.

         (a)      On each of July 15, 2008, July 15, 2013 and July 15, 2018
         (each, a "Purchase Date"), Holders shall have the option to require the
         Issuer to purchase any 2023 Notes at the Purchase Price specified in
         the 2023 Notes, upon:

                  (i)      delivery to the Paying Agent by the Holder of a
                  written notice of purchase in the form attached hereto as

                  of business on the date that is 20 Business Days prior to a
                  Purchase Date until the close of business on the fifth
                  Business Day prior to such Purchase Date, stating:

                           (A)      if certificated, the certificate numbers of
                           the 2023 Notes which the Holder will deliver to be
                           purchased, or, if not certificated, the Purchase
                           Notice must comply with appropriate Depositary
                           procedures;

                           purchased, which portion must be $1,000 in principal
                           amount or an integral multiple thereof; and

                           (C)      that such 2023 Notes shall be purchased as
                           of the Purchase Date pursuant to the terms and
                           conditions specified in the 2023 Notes and in this
                           Thirteenth Supplemental Indenture; and

                  (ii)     delivery or book-entry transfer of such 2023 Notes to
                  the Paying Agent prior to, on or after the Purchase Date
                  (together with all necessary endorsements) at the offices of
                  the Paying Agent, such delivery or transfer being a condition
                  to receipt by the Holder of the Purchase Price therefor;
                  provided, however, that such Purchase Price shall be so paid
                  pursuant to this Section 4.01 only if the 2023 Notes so
                  delivered or transferred to the Paying Agent shall conform in
                  all respects to the description thereof in the related
                  Purchase Notice.

         (b)      The Issuer shall purchase from a Holder, pursuant to the terms
         of this Section 4.01, 2023 Notes if the principal amount of such 2023
         Notes is $1,000 or a multiple of $1,000 if so requested by such Holder.

<PAGE>

         (c)      Any purchase by the Issuer contemplated pursuant to the
         provisions of this Section 4.01 shall be consummated by the delivery of
         the Purchase Price to be received by the Holder promptly following the
         later of the Purchase Date or the time of book-entry transfer or
         delivery of the 2023 Notes.

         (d)      Notwithstanding anything herein to the contrary, any Holder
         delivering to the Paying Agent the Purchase Notice contemplated by this
         Section 4.01 shall have the right at any time prior to the close of
         business on the Business Day prior to the Purchase Date to withdraw
         such Purchase Notice (in whole or in part) by delivery of a written
         notice of withdrawal to the Paying Agent in accordance with Section

         (e)      The Paying Agent shall promptly notify the Issuer of the
         receipt by it of any Purchase Notice or written notice of withdrawal
         thereof.

         (f)      On or before 10:00 a.m. (New York City time) on the Purchase
         Date, the Issuer shall deposit with the Paying Agent (or if the Issuer
         or an Affiliate of the Issuer is acting as the Paying Agent, shall
         segregate and hold in trust) money sufficient to pay the aggregate
         Purchase Price of the 2023 Notes to be purchased pursuant to this

         such Notes shall be made promptly following the later of the Purchase
         Date or the time of book-entry transfer or delivery of such 2023 Notes.
         If the Paying Agent holds, in accordance with the terms of the
         Indenture, money sufficient to pay the Purchase Price of such 2023
         Notes on the Business Day following the Purchase Date, then, on and
         after such date, such 2023 Notes shall cease to be outstanding and
         interest (including Additional Amounts, if any) on such 2023 Notes
         shall cease to accrue, whether or not book-entry transfer of such 2023
         Notes is made or such 2023 Notes are delivered to the Paying Agent, and
         all other rights of the Holder shall terminate (other than the right to
         receive the Purchase Price upon delivery or transfer of the 2023
         Notes).

         (g)      The Issuer shall require each Paying Agent (other than the
         Trustee) to agree in writing that the Paying Agent shall hold in trust
         for the benefit of Holders or the Trustee all money held by the Paying
         Agent for the payment of the Purchase Price and shall notify the
         Trustee of any default by the Issuer in making any such payment. If the
         Issuer or an Affiliate of the Issuer acts as Paying Agent, it shall
         segregate the money held by it as Paying Agent and hold it as a
         separate trust fund. The Issuer at any time may require a Paying Agent
         to deliver all money held by it to the Trustee and to account for any
         funds disbursed by the Paying Agent. Upon doing so, the Paying Agent
         shall have no further liability for the cash delivered to the Trustee.

Indenture, or (y) held by it during the continuance of an Event of Default
(other than a default that is cured by the payment of the Purchase Price or

return, the Purchase Notice or Fundamental Change Purchase Notice with respect
thereto shall be deemed to have been withdrawn.

Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing) and the Issuer shall execute and the Trustee or the
Authenticating Agent shall authenticate and deliver to the Holder of such 2023
Notes, without service charge, a new 2023 Note or 2023 Notes, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to,
and in exchange for, the portion of the principal amount of the 2023 Notes so
surrendered which is not purchased or redeemed.

         SECTION 5.04. Covenant to Comply with Securities Laws Upon Purchase of
2023 Notes. In connection with any offer to purchase 2023 Notes under Article
III or Article IV hereof, the Issuer shall, to the extent applicable: (a) comply
with Rules 13e-4 and 14e-1 (and any successor provisions thereto) under the
Exchange Act, if applicable; (b) file the related Schedule TO (or any successor
schedule, form or report) under the Exchange Act, if applicable; and (c)
otherwise comply with all applicable federal and state securities laws so as to
permit the rights and obligations under Article III or Article IV hereof to be
exercised in the time and in the manner specified in Article III or Article IV
hereof.

         SECTION 5.05. Repayment to the Issuer. The Trustee and the Paying Agent
shall return to the Issuer any cash or property that remains unclaimed as
provided in the 2023 Notes, together with interest that the Trustee or Paying
Agent, as the case may be, has agreed to pay, if any, held by them for the
payment of a Purchase Price or Fundamental Change Purchase Price, as the case
may be; provided, however, that to the extent that the aggregate amount of cash
or property deposited by the Issuer pursuant to Section 4.01(f) or Section 3.04
hereof, as applicable, exceeds the aggregate Purchase Price or Fundamental
Change Purchase Price, as the case may be, of the 2023 Notes or portions thereof
which the Issuer is obligated to purchase as of the Purchase Date or Fundamental
Change Purchase Date, as the case may be, then promptly on and after the

                                       33
<PAGE>

Business Day following the Purchase Date or Fundamental Change Purchase Date, as
the case may be, the Trustee and the Paying Agent shall return any such excess
to the Issuer together with interest that the Trustee or Paying Agent, as the
case may be, has agreed to pay, if any.

         SECTION 5.06. Officers' Certificate. At least five Business Days before
the Issuer Notice Date, the Issuer shall deliver an Officers' Certificate to the
Trustee (provided, that, at the Issuer's option, the matters to be addressed in
such Officers' Certificate may be divided among two such certificates)
specifying:

         (a)      the manner of payment selected by the Issuer; and

         (b)      whether the Issuer desires the Trustee to give the Issuer
         Notice required by Section 5.01 hereof.

                                   ARTICLE VI

                            CONVERSION OF 2023 NOTES

         SECTION 6.01. Right to Convert. A Holder may convert its 2023 Notes for
Common Stock at any time during which the conditions stated in the 2023 Notes
are met. The number of shares of Common Stock issuable upon conversion of a 2023
Note per $1,000 principal amount (the "Conversion Rate") shall be that set forth
in the 2023 Notes, subject to adjustment as herein set forth. The initial
Conversion Rate is 93.7137 shares of Common Stock issuable upon conversion of a
2023 Note per $1,000 principal amount.

         A Holder may convert a portion of the principal amount of 2023 Notes if
the portion is $1,000 or a multiple of $1,000.

         SECTION 6.02. Conversion Procedures. To convert 2023 Notes, a Holder
must satisfy the requirements in this Section 6.02 and in the 2023 Notes. The
date on which the Holder satisfies all those requirements is the conversion date
(the "Conversion Date"). As soon as practicable, but in no event later than the
fifth Business Day following the Conversion Date, the Issuer shall deliver to
the Holder, through the Conversion Agent, a certificate for the number of full
shares of Common Stock issuable upon the conversion and cash or a check in lieu
of any fractional share determined pursuant to Section 6.03 hereof. The Person
in whose name the certificate is registered shall be treated as a stockholder of
record on and after the Conversion Date; provided, however, that no surrender of
2023 Notes on any date when the stock transfer books of the Issuer shall be
closed shall be effective to constitute the Person or Persons entitled to
receive the shares of Common Stock upon such conversion as the record holder or
holders of such shares of Common Stock on such date, but such surrender shall be
effective to constitute the Person or Persons entitled to receive such shares of
Common Stock as the record holder or holders thereof for all purposes at the
close of business on the next succeeding day on which such stock transfer books
are open; such conversion shall be at the Conversion Rate in effect on the date
that such 2023 Notes shall have been surrendered for conversion, as if the stock
transfer books of the Issuer had not been closed. Upon conversion of 2023 Notes,
such Person shall no longer be a Holder of such 2023 Notes.

                                       34
<PAGE>

         No payment or adjustment shall be made for dividends on or other
distributions with respect to any Common Stock except as provided in Section
6.06 hereof or as otherwise provided in this Indenture.

         On conversion of 2023 Notes, that portion of accrued interest with
respect to the converted 2023 Notes shall not be canceled, extinguished or
forfeited, but rather shall be deemed to be paid in full to the Holder thereof
through delivery of the Common Stock (together with the cash or check payment,
if any, in lieu of fractional shares) in exchange for the 2023 Notes being
converted pursuant to the provisions hereof, and the Fair Market Value of such
shares of Common Stock (together with any such cash or check payment in lieu of
fractional shares) shall be treated as issued, to the extent thereof, first in
exchange for interest accrued and unpaid through the Conversion Date, and the
balance, if any, of such Fair Market Value of such Common Stock (and any such
cash or check payment) shall be treated as issued in exchange for the principal
amount of the 2023 Notes being converted pursuant to the provisions hereof.
Notwithstanding conversion of any 2023 Notes, the Holders of the 2023 Notes and
any Common Stock issuable upon conversion thereof will continue to be entitled
to receive Additional Amounts in accordance with the Registration Rights
Agreement.

         If a Holder converts more than one 2023 Note at the same time, the
number of shares of Common Stock issuable upon the conversion shall be based on
the total principal amount of the 2023 Notes converted.

         Upon surrender of a 2023 Note that is converted in part, the Issuer
shall execute, and the Trustee or the Authenticating Agent shall authenticate
and deliver to the Holder, a new 2023 Note in an authorized denomination equal
in principal amount to the unconverted portion of the 2023 Note surrendered.

         If the last day on which 2023 Notes may be converted is a legal holiday
in a place where a Conversion Agent is located, the 2023 Notes may be
surrendered to that Conversion Agent on the next succeeding day that it is not a
legal holiday.

         SECTION 6.03. Cash or Check Payments in Lieu of Fractional Shares. The
Issuer shall not issue a fractional share of Common Stock upon conversion of
2023 Notes. Instead the Issuer shall deliver cash (or Issuer's check) for the
current market value of the fractional share. The current market value of a
fractional share shall be determined to the nearest 1/10,000th of a share by
multiplying the Last Reported Sale Price of a full share of Common Stock on the
Trading Day immediately preceding the Conversion Date by the fractional amount
and rounding the product to the nearest whole cent.

         SECTION 6.04. Taxes on Conversion. If a Holder converts 2023 Notes, the
Issuer shall pay any documentary, stamp or similar issue or transfer tax due on
the issue of shares of Common Stock upon the conversion. However, the Holder
shall pay any such tax which is due because the Holder requests the shares to be
issued in a name other than the Holder's name. The Conversion Agent may refuse
to deliver the certificates representing the Common Stock being issued in a name
other than the Holder's name until the Conversion Agent receives a sum

                                       35
<PAGE>

sufficient to pay any tax which shall be due because the shares are to be issued
in a name other than the Holder's name. Nothing herein shall preclude any
withholding tax required by law.

         SECTION 6.05. Covenants of the Issuer. The Issuer shall, prior to
issuance of any 2023 Notes hereunder, and from time to time as may be necessary,
reserve out of its authorized but unissued Common Stock a sufficient number of
shares of Common Stock to permit the conversion of the 2023 Notes.

         All shares of Common Stock delivered upon conversion of the 2023 Notes
shall be newly issued shares or treasury shares, shall be duly and validly
issued and fully paid and nonassessable and shall be free from preemptive rights
and free of any lien or adverse claim.

         The Issuer shall endeavor promptly to comply with all federal and state
securities laws regulating the order and delivery of shares of Common Stock upon
the conversion of 2023 Notes, if any, and shall cause to have listed or quoted
all such shares of Common Stock on each United States national securities
exchange or over-the-counter or other domestic market on which the Common Stock
is then listed or quoted.

         SECTION 6.06. Adjustments to Conversion Rate. The Conversion Rate shall
be adjusted from time to time, without duplication, as follows:

         (a)      In case the Issuer shall: (i) pay a dividend, or make a
         distribution, exclusively in shares of its capital stock, on the Common
         Stock; (ii) subdivide its outstanding Common Stock into a greater
         number of shares; (iii) combine its outstanding Common Stock into a
         smaller number of shares; or (iv) reclassify its Common Stock, the
         Conversion Rate in effect immediately prior to the record date or
         effective date, as the case may be, for the adjustment pursuant to this
         Section 6.06(a) as described below, shall be adjusted so that the
         Holder of any 2023 Notes thereafter surrendered for conversion shall be
         entitled to receive the number of shares of Common Stock of the Issuer
         which such Holder would have owned or have been entitled to receive
         after the happening of any of the events described above had such 2023
         Notes been converted immediately prior to such record date or effective
         date, as the case may be. An adjustment made pursuant to this Section
         6.06(a) shall become effective immediately after the applicable record
         date in the case of a dividend or distribution and shall become
         effective immediately after the applicable effective date in the case
         of subdivision, combination or reclassification of the Issuer's Common
         Stock. If any dividend or distribution of the type described in clause
         (i) above is not so paid or made, the Conversion Rate shall again be
         adjusted to the Conversion Rate which would then be in effect if such
         dividend or distribution had not been declared.

         (b)      In case the Issuer shall issue rights or warrants to all
         holders of the Common Stock entitling them (for a period expiring
         within 60 days after the date of issuance of such rights or warrants)
         to subscribe for or purchase Common Stock at a price per share less
         than the Market Price per share of Common Stock on the record date
         fixed for determination of shareholders entitled to receive such rights
         or warrants, the Conversion Rate in effect

                                       36
<PAGE>

         immediately after such record date shall be adjusted so that the same
         shall equal the Conversion Rate determined by multiplying the
         Conversion Rate in effect immediately after such record date by a
         fraction of which (i) the numerator shall be the number of shares of
         Common Stock outstanding on such record date plus the number of
         additional shares of Common Stock offered for subscription or purchase,
         and (ii) the denominator shall be the number of shares of Common Stock
         outstanding on such record date plus the number of shares which the
         aggregate offering price of the total number of shares so offered would
         purchase at the Market Price per share of Common Stock on the earlier
         of such record date or the Trading Day immediately preceding the ex
         date for such issuance of rights or warrants. Such adjustment shall be
         made successively whenever any such rights or warrants are issued, and
         shall become effective immediately after the opening of business on the
         day following the record date for the determination of shareholders
         entitled to receive such rights or warrants. To the extent that shares
         of Common Stock are not delivered after the expiration of such rights
         or warrants, the Conversion Rate shall be readjusted to the Conversion
         Rate which would then be in effect had the adjustments made upon the
         issuance of such rights or warrants been made on the basis of delivery
         of only the number of shares of Common Stock actually delivered. If
         such rights or warrants are not so issued, the Conversion Rate shall
         again be adjusted to be the Conversion Rate which would then be in
         effect if such record date for the determination of shareholders
         entitled to receive such rights or warrants had not been fixed. In
         determining whether any rights or warrants entitle the holders to
         subscribe for or purchase shares of Common Stock at less than such
         Market Price, and in determining the aggregate offering price of such
         shares of Common Stock, there shall be taken into account any
         consideration received by the Issuer for such rights or warrants, the
         value of such consideration, if other than cash, to be determined by
         the Board of Directors.

         (c)      In case the Issuer shall, by dividend or otherwise, distribute
         to all holders of Common Stock any assets, debt securities or rights or
         warrants to purchase any of its securities (excluding (i) any dividend,
         distribution or issuance covered by those referred to in Section
         6.06(a) or Section 6.06(b) hereof and (ii) any dividend or distribution
         paid exclusively in cash) (any of the foregoing hereinafter in this
         Section 6.06(c) called the "Distributed Assets or Securities") in an
         aggregate amount per share of Common Stock that, combined together with
         the aggregate amount of any other such distributions to all holders of
         its Common Stock made within the 12 months preceding the date of
         payment of such distribution, and in respect of which no adjustment
         pursuant to this Section 6.06(c) has been made, exceeds 15% of the
         Market Price on the Trading Day immediately preceding the declaration
         of such distribution, then the Conversion Rate shall be adjusted so
         that the same shall equal the Conversion Rate determined by multiplying
         the Conversion Rate in effect immediately prior to the close of
         business on the record date mentioned below by a fraction of which (A)
         the numerator shall be the Market Price per share of the Common Stock
         on the earlier of such record date or the Trading Day immediately
         preceding the ex date for such dividend or distribution, and (B) the
         denominator shall be (1) the Market Price per share of the Common Stock
         on the earlier of such record date or the Trading Day immediately
         preceding the ex date for such dividend or distribution less (2) the
         Fair Market Value on the earlier of such record date or the Trading Day
         immediately preceding the ex date for such dividend or distribution (as
         determined by the Board of Directors, whose determination shall be
         conclusive, and described in a certificate filed with the Trustee and
         the Paying Agent) of the Distributed

                                       37
<PAGE>

         Assets or Securities so distributed applicable to one share of Common
         Stock. Such adjustment shall become effective immediately after the
         record date for the determination of shareholders entitled to receive
         such distribution; provided, however, that, if (i) the Fair Market
         Value of the portion of the Distributed Assets or Securities so
         distributed applicable to one share of Common Stock is equal to or
         greater than the Market Price of the Common Stock on the record date
         for the determination of shareholders entitled to receive such
         distribution or (ii) the Market Price of the Common Stock on the record
         date for the determination of shareholders entitled to receive such
         distribution is greater than the Fair Market Value per share of such
         Distributed Assets or Securities by less than $1.00, then, in lieu of
         the foregoing adjustment, adequate provision shall be made so that each
         Holder shall have the right to receive upon conversion, in addition to
         the shares of Common Stock, the kind and amount of assets, debt
         securities, or rights or warrants comprising the Distributed Assets or
         Securities the Holder would have received had such Holder converted
         such 2023 Notes immediately prior to the record date for the
         determination of shareholders entitled to receive such distribution. In
         the event that such distribution is not so paid or made, the Conversion
         Rate shall again be adjusted to the Conversion Rate which would then be
         in effect if such distribution had not been declared.

         (d)      In case the Issuer shall make (i) any distributions, by
         dividend or otherwise, during any quarterly fiscal periods consisting
         exclusively of cash to all holders of outstanding shares of Common
         Stock in an aggregate amount that, together with (ii) other all-cash or
         all-check distributions made to all holders of outstanding shares of
         Common Stock during such quarterly fiscal period, and (iii) any cash
         and the Fair Market Value, as of the expiration of any tender or
         exchange offer (other than consideration payable in respect of any
         odd-lot tender offer) of consideration payable in respect of any tender
         or exchange offer by the Issuer or any of the Issuer's Subsidiaries for
         all or any portion of shares of Common Stock concluded during such
         quarterly fiscal period, exceed the product of $0 multiplied by the
         number of shares of Common Stock outstanding on the record date for
         such distribution, then, and in each such case, the Conversion Rate
         shall be adjusted so that the same shall equal the Conversion Rate
         determined by multiplying the Conversion Rate in effect immediately
         prior to the close of business on the record date fixed for the
         determination of holders of Common Stock entitled to receive such
         distribution by a fraction of which (A) the numerator shall be the
         Market Price per share of the Common Stock on the earlier of such
         record date or the Trading Day immediately preceding the ex date for
         such dividend or distribution and (B) the denominator shall be (1) the
         Market Price per share of Common Stock on the earlier of such record
         date or the Trading Day immediately preceding the ex date for such
         dividend or distribution plus (2) $0 less (3) an amount equal to the
         quotient of (x) the combined amount distributed or payable in the
         transactions described in clauses (i), (ii) and (iii) above during such
         quarterly fiscal period and (y) the number of shares of Common Stock
         outstanding on such record date, such adjustment to become effective
         immediately after the record date for the determination of shareholders
         entitled to receive such distribution.

         (e)      With respect to Section 6.06(c) hereof, in the event that the
         Issuer makes any distribution to all holders of Common Stock consisting
         of Equity Interests in a Subsidiary or other business unit of the
         Issuer, the Conversion Rate shall be adjusted so that the

                                       38
<PAGE>

         same shall equal the Conversion Rate determined by multiplying the
         Conversion Rate in effect immediately prior to the close of business on
         the record date fixed for the determination of holders of Common Stock
         entitled to receive such distribution by a fraction of which (i) the
         numerator shall be (x) the Spin-off Market Price per share of the
         Common Stock on such record date plus (y) the Spin-off Market Price per
         Equity Interest of the Subsidiary or other business unit of the Issuer
         on such record date and (ii) the denominator shall be the Spin-off
         Market Price per share of the Common Stock on such record date, such
         adjustment to become effective 10 Trading Days after the effective date
         of such distribution of Equity Interests in a Subsidiary or other
         business unit of the Issuer.

         (f)      Upon conversion of the 2023 Notes, the Holders shall receive,
         in addition to the Common Stock issuable upon such conversion, the
         rights issued under any future shareholder rights plan the Issuer
         implements (notwithstanding the occurrence of an event causing such
         rights to separate from the Common Stock at or prior to the time of
         conversion) unless, prior to conversion, the rights have expired,
         terminated or been redeemed or exchanged in accordance with such rights
         plan. If, and only if, the Holders of 2023 Notes receive rights under
         such shareholder rights plans as described in the preceding sentence
         upon conversion of their 2023 Notes, then no other adjustment pursuant
         to this Section 6.06 shall be made in connection with such shareholder
         rights plans.

         (g)      For purposes of this Section 6.06, the number of shares of
         Common Stock at any time outstanding shall not include shares held in
         the treasury of the Issuer but shall include shares issuable in respect
         of scrip certificates issued in lieu of fractions of shares of Common
         Stock. The Issuer shall not pay any dividend or make any distribution
         on shares of Common Stock held in the treasury of the Issuer.

         (h)      Notwithstanding the foregoing, in no event shall the
         Conversion Rate exceed the maximum conversion rate specified under this
         Section 6.06(h) (the "Maximum Conversion Rate") as a result of an
         adjustment pursuant to Section 6.06(c) and Section 6.06(d) hereof. The
         Maximum Conversion Rate shall initially be 138.6963 and shall be
         appropriately adjusted from time to time for any stock dividends on or
         subdivisions or combinations of the Common Stock. The Maximum
         Conversion Rate shall not apply to any adjustments made pursuant to any
         of the events in Section 6.06(a) or Section 6.06(b) hereof.

         SECTION 6.07. Calculation Methodology. No adjustment in the Conversion
Price need be made unless the adjustment would require an increase or decrease
of at least 1% in the Conversion Price then in effect, provided that any
adjustment that would otherwise be required to be made shall be carried forward
and taken into account in any subsequent adjustment. Except as stated in this
Article VI, the Conversion Rate will not be adjusted for the issuance of Common
Stock or any securities convertible into or exchangeable for Common Stock or
carrying the right to purchase any of the foregoing. Any adjustments that are
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under Article V and Section 6.06 hereof and this
Section 6.07 shall be made to the nearest cent or to the nearest 1/10,000th of a
share, as the case may be.

                                       39
<PAGE>

         SECTION 6.08. When No Adjustment Required. No adjustment to the
Conversion Rate need be made:

         (a)      upon the issuance of any shares of Common Stock pursuant to
         any present or future plan providing for the reinvestment of dividends
         or interest payable on securities of the Issuer and the investment of
         additional optional amounts in shares of Common Stock under any plan;

         (b)      upon the issuance of any shares of Common Stock or options or
         rights to purchase those shares pursuant to any present or future
         employee, director or consultant benefit plan or program of or assumed
         by the Issuer or any of its Subsidiaries;

         (c)      upon the issuance of any shares of Common Stock pursuant to
         any option, warrant, right, or exercisable, exchangeable or convertible
         security not described in clause (b) above and outstanding as of the
         date of this Thirteenth Supplemental Indenture;

         (d)      for a change in the par value or no par value of the Common
         Stock;

         (e)      for accrued and unpaid interest (including Additional Amounts,
         if any); or

         (f)      if Holders are to participate in a merger or consolidation on
         a basis and with notice that the Board of Directors determines to be
         fair and appropriate in light of the basis and notice on which holders
         of Common Stock participate in the transaction; provided that the basis
         on which the Holders are to participate in the transaction shall not be
         deemed to be fair if it would require the conversion of Securities at
         any time prior to the expiration of the conversion period specified for
         such Securities.

         To the extent the 2023 Notes become convertible into cash, assets, or
property (other than capital stock of the Issuer or securities to which Section
6.12 hereof applies), no adjustment shall be made thereafter as to the cash,
assets or property. Interest shall not accrue on such cash.

         SECTION 6.09. Notice of Adjustment. Whenever the Conversion Rate is
adjusted, the Issuer shall promptly mail to Holders a notice of the adjustment.
The Issuer shall file with the Trustee and the Conversion Agent such notice. The
certificate shall, absent manifest error, be conclusive evidence that the
adjustment is correct. Neither the Trustee nor any Conversion Agent shall be
under any duty or responsibility with respect to any such certificate except to
exhibit the same to any Holder desiring inspection thereof.

         SECTION 6.10. Voluntary Increase. The Issuer may make such increases in
the Conversion Rate, in addition to those required by Section 6.06 hereof, as
the Board of Directors considers to be advisable to avoid or diminish any income
tax to holders of Common Stock or rights to purchase Common Stock resulting from
any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes. To the extent permitted by
applicable law, the Issuer may from time to time increase the Conversion Rate by
any amount, temporarily or otherwise, for any period of at least 20 days if the
increase is irrevocable during the period and the Board of Directors shall have
made a determination that

                                       40
<PAGE>

such increase would be in the best interests of the Issuer, which determination
shall be conclusive. Whenever the Conversion Rate is so increased, the Issuer
shall mail to Holders and file with the Trustee and the Conversion Agent a
notice of such increase. Neither the Trustee nor any Conversion Agent shall be
under any duty or responsibility with respect to any such notice except to
exhibit the same to any holder desiring inspection thereof. The Issuer shall
mail the notice at least 15 days before the date the increased Conversion Rate
takes effect. The notice shall state the increased Conversion Rate and the
period it shall be in effect.

         SECTION 6.11. Notice to Holders Prior to Certain Actions. In case:

         (a)      the Issuer shall declare a dividend (or any other
         distribution) on its Common Stock that would require an adjustment in
         the Conversion Rate pursuant to Section 6.06 hereof;

         (b)      the Issuer shall authorize the granting to all or
         substantially all the holders of its Common Stock of rights or warrants
         to subscribe for or purchase any share of any class or any other rights
         or warrants;

         (c)      of any reclassification or reorganization of the Common Stock
         of the Issuer (other than a subdivision or combination of its
         outstanding Common Stock, or a change in par value, or from par value
         to no par value, or from no par value to par value), or of any
         consolidation or merger to which the Issuer is a party and for which
         approval of any shareholders of the Issuer is required, or of the sale
         or transfer of all or substantially all of the assets of the Issuer; or

         (d)      of the voluntary or involuntary dissolution, liquidation or
         winding-up of the Issuer,

         the Issuer shall cause to be filed with the Trustee and to be mailed to
         each Holder at its address appearing on the Security Register, as
         promptly as possible but in any event at least 15 days prior to the
         applicable date hereinafter specified, a notice stating (x) the date on
         which a record is to be taken for the purpose of such dividend,
         distribution or rights or warrants, or, if a record is not to be taken,
         the date as of which the holders of Common Stock of record to be
         entitled to such dividend, distribution, or rights or warrants are to
         be determined or (y) the date on which such reclassification,
         reorganization, consolidation, merger, sale, transfer, dissolution,
         liquidation or winding-up is expected to become effective or occur, and
         the date as of which it is expected that holders of Common Stock of
         record shall be entitled to exchange their Common Stock for securities
         or other property deliverable upon such reclassification,
         reorganization, consolidation, merger, sale, transfer, dissolution,
         liquidation or winding-up. Failure to give such notice, or any defect
         therein, shall not affect the legality or validity of such dividend,
         distribution, reclassification, reorganization, consolidation, merger,
         sale, transfer, dissolution, liquidation or winding-up.

         SECTION 6.12. Effect of Reclassification, Consolidation, Merger,
Binding Share Exchange or Sale. If any of the following events occur, namely:
(a) any reclassification or

                                       41
<PAGE>

change of outstanding shares of Common Stock (other than a change in par value,
or from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination); (b) any consolidation, merger,
combination or binding share exchange of the Issuer with another Person as a
result of which holders of Common Stock shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock; or (c) any sale or conveyance of the properties
and assets of the Issuer as, or substantially as, an entirety to any other
Person as a result of which holders of Common Stock shall be entitled to receive
stock, securities or other property or assets (including cash) with respect to
or in exchange for such Common Stock, then the Issuer or the successor or
purchasing Person, as the case may be, shall execute with the Trustee a
supplemental indenture to the Indenture, providing that each 2023 Note shall be
convertible into the kind and amount of shares of stock and other securities or
property or assets (including cash) receivable upon such reclassification,
change, consolidation, merger, combination, binding share exchange, sale or
conveyance by a holder of a number of shares of Common Stock issuable upon
conversion of such 2023 Note immediately prior to such reclassification, change,
consolidation, merger, combination, binding share exchange, sale or conveyance.
Such supplemental indenture shall provide for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section 6.12.

         The Issuer shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder, at its address appearing on the Security
Register, within 20 days after execution thereof. Failure to deliver such notice
shall not affect the legality or validity of such supplemental indenture.

         The above provisions of this Section 6.12 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
binding share exchanges, sales and conveyances.

         If this Section 6.12 applies to any event or occurrence, Section 6.06
hereof shall not apply.

         SECTION 6.13. Responsibility of Trustee. The Trustee and any other
Conversion Agent shall not at any time be under any duty or responsibility to
any Holder to either calculate the Conversion Rate or determine whether any
facts exist which may require any adjustment of the Conversion Rate, or with
respect to the nature or extent or calculation of any such adjustment when made,
or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same and shall be protected in
relying upon an Officers' Certificate with respect to the same. The Trustee and
any other Conversion Agent shall not be accountable with respect to the validity
or value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the
conversion of any 2023 Notes and the Trustee and any other Conversion Agent make
no representations with respect thereto. Subject to the provisions of Article
Six of the Original Indenture, neither the Trustee nor any Conversion Agent
shall be responsible for any failure of the Issuer to issue, transfer or deliver
any shares of Common Stock or stock certificates or other securities or property
or cash upon the surrender of any 2023 Notes for the purpose of conversion or to
comply with any of the duties, responsibilities or covenants of the Issuer
contained in this

                                       42
<PAGE>

Section 6.13. Without limiting the generality of the foregoing, neither the
Trustee nor any Conversion Agent shall be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Article VI hereof relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by
Holders upon the conversion of their 2023 Notes after any event referred to in
such Section 6.12 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Article Six of the Original Indenture, may accept
as conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officers' Certificate (which the Issuer shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

         SECTION 6.14. Simultaneous Adjustments. In the event that Section 6.06
hereof requires adjustments to the Conversion Rate under more than one of
Section 6.06(a), Section 6.06(b), Section 6.06(c) or Section 6.06(d) hereof, and
the Record Dates for the distributions giving rise to such adjustments shall
occur on the same date, then such adjustments shall be made by applying, first,
the provisions of Section 6.06(c) hereof, second, the provisions of Section
6.06(a) hereof and third, the provisions of Section 6.06(b) hereof; provided,
however, that nothing in this Section 6.14 shall be done to evade the principle
set forth in Section 6.06(h) hereof that the Maximum Conversion Rate shall not
apply to any adjustments made with respect to any of the events in Section
6.06(a) or Section 6.06(b) hereof.

         SECTION 6.15. Successive Adjustments. After an adjustment to the
Conversion Rate under Section 6.06 hereof, any subsequent event requiring an
adjustment under Section 6.06 shall cause an adjustment to the Conversion Rate
as so adjusted.

         SECTION 6.16. General Considerations. Whenever successive adjustments
to the Conversion Rate are called for pursuant to this Article VI, such
adjustments shall be made to the Market Price as may be necessary or appropriate
to effectuate the intent of this Article VI and to avoid unjust or inequitable
results as determined in good faith by the Board of Directors.

         SECTION 6.17. Issuer Determination Final. Any determination which the
Board of Directors must make pursuant to this Article VI shall be conclusive and
binding on the Holders.

         SECTION 6.18. Conversion Provisions. Pursuant to Section 2.3(f)(10) of
the Original Indenture, the obligation of the Issuer to permit the conversion of
the 2023 Notes into Common Stock and the terms and conditions upon which such
conversion shall be effected set forth in this Thirteenth Supplemental Indenture
are in addition to and in lieu of those provisions set forth in Article Thirteen
of the Original Indenture relative to such obligation.

                         WITH RESPECT TO THE 2023 NOTES

         SECTION 7.01. Existence. So long as any of the 2023 Notes are
outstanding, subject to Article 9 of the Original Indenture, the Issuer will do
or cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence.

         SECTION 7.02. Limitation on Certain Liens. (a) So long as any of the
2023 Notes are outstanding, the Issuer shall not create, incur, assume or suffer
to 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 7.02 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 2023 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:

         (i)      Liens for taxes, assessments or governmental charges or levies
         to the extent not past due;

         (ii)     pledges or deposits to secure (A) obligations under workmen's
         compensation laws or similar legislation, (B) statutory obligations of

         arising in the ordinary course of business securing obligations which
         are not overdue or which have been fully bonded and are being contested
         in good faith;

         (iv)     purchase money Liens upon or in property acquired and held by
         the Issuer in the ordinary course of business to secure the purchase
         price of such property or to secure Indebtedness incurred solely for
         the purpose of financing the acquisition of any such property to be
         subject to such Liens, or Liens existing on any such property at the
         time of acquisition, or extensions, renewals or replacements of any of
         the foregoing for the same or a lesser amount, provided that no such
         Lien shall extend to or cover any property other than the property
         being acquired and no such extension, renewal or replacement shall
         extend to or cover property not theretofore subject to the Lien being
         extended, renewed or replaced, and provided, further, that the
         aggregate principal amount of the Indebtedness at any one time
         outstanding secured by Liens permitted by this clause (iv) shall not
         exceed $10,000,000; and

                                       44
<PAGE>

         (v)      Liens not otherwise permitted by clauses (i) through (iv) of
         this Section 7.02 securing Indebtedness of the Issuer; provided that on
         the date such Liens are created, and after giving effect to such
         Indebtedness, the aggregate principal amount at maturity of all of the
         secured Indebtedness of the Issuer at such date shall not exceed 5% of
         Consolidated Net Tangible Assets at such date.

         SECTION 7.03. Limitation on Consolidation, Merger, Sale or Conveyance.
So long as any of the 2023 Notes are outstanding and until the 2023 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 7.03,
and subject also to Article Nine of the Original 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
(a) 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 (b) after giving effect to
such transaction, the surviving entity would be entitled to incur at least one
dollar of additional Indebtedness (other than revolving Indebtedness to banks)
without violation of the limitations in Section 7.04 hereof.

         SECTION 7.04. Limitation on Consolidated Indebtedness.

         (a)      So long as any of the 2023 Notes are outstanding and until the
2023 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 7.04, 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 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 1.6 to 1.0.

                  Thirteenth Supplemental Indenture, as set forth on Schedule
                  7.04(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 on, the Indebtedness so exchanged,
                  refunded or refinanced and (ii) the Indebtedness so issued (A)

                  refunded or refinanced is subordinated to the 2023 Notes, the
                  Indebtedness is subordinated to the 2023 Notes in right of
                  payment;

                  (3)      Indebtedness of the Issuer owed to and held by a
                  Subsidiary and Indebtedness of a Subsidiary owed to and held

                  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 Section 7.04(b) to constitute the issuance of such
                  Indebtedness by the Issuer;

                  such Indebtedness is without recourse to the assets of
                  Consumers.

         SECTION 7.05. Limitation on Restricted Payments.

         (a)      So long as the 2023 Notes are outstanding and until the 2023
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 7.05, 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 herein
referred to as a "Restricted Payment") if at the time the Issuer or such
Subsidiary makes such Restricted Payment:

                                       47
<PAGE>

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

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

                  (A)      $100,000,000;

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

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

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

         (b)      The provisions of Section 7.05(a) hereof shall not prohibit:

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

                  (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 7.05; 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

                                       48
<PAGE>

                  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 7.06. Limitation on Asset Sales. So long as any of the 2023
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 2023 Notes, (ii) invest an equal amount not so used in
clause (i) in property or assets of related business within 24 months after the
date of the Asset Sale (the "Application Period") or (iii) apply such excess Net
Cash Proceeds not so used in clause (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 2023 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 2023 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 2023 Notes from
Holders pursuant to clause (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 2023 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 5.01 herein with respect to a Fundamental Change.

                                  ARTICLE VIII

                          ADDITIONAL EVENTS OF DEFAULT
                         WITH RESPECT TO THE 2023 NOTES

         SECTION 8.01. 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 2023 Notes.

         SECTION 8.02. Amendments to Section 5.1 of the Original Indenture.
Solely for the purpose of determining Events of Default with respect to the 2023
Notes, paragraphs Section 5.1(e), Section 5.1(f) and Section 5.1(h) 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.

         SECTION 8.03. Additional Events of Default. Solely for the purpose of
determining Events of Default with respect to the 2023 Notes, an Event of
Default shall also include the following:

(i)      default in the payment of any interest upon any 2023 Note, including
Additional Amounts, if any, when it becomes due and payable, and continuance of
such default for 30 days;

                                       49
<PAGE>

(ii)     default in the Issuer's obligation to redeem the 2023 Notes after
exercising its redemption option pursuant to Article XIII hereof;

(iii)    default in the Issuer's obligation to convert the 2023 Notes upon
exercise of a Holder's conversion right in accordance with the terms of the 2023
Notes and Article VI hereof; and

(iv)     default in the Issuer's obligation to purchase 2023 Notes upon the
occurrence of a Fundamental Change or the exercise by a Holder of its option to
require the Issuer to repurchase such Holder's 2023 Notes in accordance with the
terms of Article III or Article IV hereof, as applicable.

                                   ARTICLE IX

                                  GLOBAL NOTES

         The 2023 Notes will be issued initially in the form of Global Notes.
"Global Note" means a registered 2023 Note evidencing one or more 2023 Notes
issued to a depositary (the "Depositary") or its nominee, in accordance with
this Article IX and bearing the legend prescribed in this Article IX. One or
more Global Notes will represent all 2023 Notes. The Issuer shall execute and
the Trustee shall, in accordance with this Article IX and the Issuer Order with
respect to the 2023 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 2023 Notes to
be represented by such Global Note or Global Notes, (ii) shall be registered in
the name of the Depositary for such Global Note or Global 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 2023 Note is presented
by an authorized representative of the Depositary to the Issuer or its agent for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of a nominee of the Depositary or in such other name as
is requested by an authorized representative of the Depositary (and any payment
is made to such nominee of the Depositary or to such other entity as is
requested by an authorized representative of the Depositary), 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 Original Indenture, unless and until
it is exchanged in whole or in part for 2023 Notes in definitive form, a Global
Note representing one or more 2023 Notes may not be transferred except as a
whole by the Depositary, to a nominee of such Depository 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 2023 Notes or a
nominee of such successor Depositary.

         If at any time the Depositary for the 2023 Notes is unwilling or unable
to continue as Depositary for the 2023 Notes, the Issuer shall appoint a
successor Depositary with respect to the 2023 Notes. If a successor Depositary
for the 2023 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

                                       50
<PAGE>

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 2023 Notes, will authenticate and deliver 2023 Notes in definitive
form in an aggregate principal amount equal to the principal amount of the
Global Note or Global Notes representing such 2023 Notes in exchange for such
Global Note or Global Notes.

         The Issuer may at any time and in its sole discretion determine that
the 2023 Notes issued in the form of one or more Global Notes shall no longer be
represented by such Global Note or Global Notes. In such event the Issuer will
execute, and the Trustee, upon receipt of an Issuer Order for the authentication
and delivery of definitive 2023 Notes, will authenticate and deliver 2023 Notes
in definitive form in an aggregate principal amount equal to the principal
amount of the Global Note or Global Notes representing such 2023 Notes in
exchange for such Global Note or Global Notes.

         The Depositary for such 2023 Notes may surrender a Global Note or
Global Notes for such 2023 Notes in exchange in whole or in part for 2023 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:

         (i)      to each Person specified by such Depositary a new 2023 Note or
         2023 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 2023
         Notes in definitive form delivered to Holders thereof.

         In any exchange provided for in this Article IX, the Issuer will
execute and the Trustee will authenticate and deliver 2023 Notes in definitive
registered form in authorized denominations.

         Upon the exchange of a Global Note for 2023 Notes in definitive form,
such Global Note shall be cancelled by the Trustee. 2023 Notes in definitive
form issued in exchange for a Global Note pursuant to this Article IX 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 2023 Notes to the Persons in whose names such 2023
Notes are so registered.

                                   DEFEASANCE

         All of the provisions of Article Ten of the Original Indenture shall be
applicable to the 2023 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 under Article VII and Article XIII of this Thirteenth Supplemental
Indenture with respect to the 2023 Notes.

                                   ARTICLE XI

                             SUPPLEMENTAL INDENTURES

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

                                   ARTICLE XII

                             MODIFICATION AND WAIVER

         In addition to those matters set forth in Section 8.2 of the Original
Indenture (including the terms and conditions of the 2023 Notes set forth
herein), with respect to the 2023 Notes, no amendment or supplemental indenture
to the Indenture shall, without the consent of the Holder of each 2023 Note
affected thereby:

(a)      reduce the Redemption Price, Purchase Price or Fundamental Change
Purchase Price of the 2023 Notes;

(b)      change the terms applicable to redemption or purchase of the 2023 Notes
in a manner adverse to the Holder; or

(c)      alter the manner of calculation or rate of Additional Amounts payable
on any 2023 Note or extend the time for payment of any such amount.

In addition, with respect to the 2023 Notes, notwithstanding Section 5.10 of the
Original Indenture, approval of the Holders of each outstanding 2023 Note shall
be required to:

(a)      waive any default by the Issuer in any payment of the Redemption Price,
Purchase Price or Fundamental Change Purchase Price with respect to any 2023
Notes; or

(b)      waive any default which constitutes a failure to convert any 2023 Note
in accordance with its terms and the terms of Article VI hereof.

                                       52
<PAGE>

The reference to "interest" in Section 5.10(i) of the Original Indenture shall
include Additional Amounts, if any.

                                  ARTICLE XIII

                      OPTIONAL REDEMPTION OF THE 2023 NOTES

         SECTION 13.01. Right to Redeem; Notice to Trustee, Paying Agent and
Holders. On or after July 15, 2008, the Issuer may, at its option, redeem the
2023 Notes in whole, or in part, at any time in accordance with the provisions
of the 2023 Notes. If the Issuer elects to redeem 2023 Notes pursuant to the
provisions of the 2023 Notes, it shall notify in writing the Trustee, the Paying
Agent and each Holder of 2023 Notes to be redeemed, as provided in Section 11.2
of the Indenture and Section 13.04 hereof.

         SECTION 13.02. Fewer Than All Outstanding 2023 Notes to Be Redeemed. If
fewer than all of the outstanding 2023 Notes are to be redeemed, the Trustee
shall select the 2023 Notes to be redeemed in principal amounts of $1,000 or
integral multiples thereof. In the case that the Trustee shall select the 2023
Notes to be redeemed, the Trustee may effectuate such selection by lot, pro
rata, or by any other method that the Trustee considers fair and appropriate.
The Trustee will make such selection promptly following receipt of the notice of
redemption from the Issuer provided pursuant to Section 13.04 hereof.

         SECTION 13.03. Selection of 2023 Notes to Be Redeemed. If any 2023
Notes selected for partial redemption are thereafter surrendered for conversion
in part before termination of the conversion right with respect to the portion
of the 2023 Notes so selected, the converted portion of such 2023 Notes shall be
deemed (so far as may be), solely for purposes of determining the aggregate
principal amount of 2023 Notes to be redeemed by the Issuer, to be the portion
selected for redemption. 2023 Notes which have been converted during a selection
of 2023 Notes to be redeemed may be treated by the Trustee as outstanding for
the purpose of such selection. Nothing in this Section 13.03 shall affect the
right of any Holder to convert any 2023 Notes pursuant to Article VI hereof
before the termination of the conversion right with respect thereto.

         SECTION 13.04. Notice of Redemption. In addition to those matters set
forth in Section 11.2 of the Indenture, a notice of redemption sent to Holders
of 2023 Notes shall state:

         (a)      the then current Conversion Rate;

         (b)      the name and address of the Paying Agent and the Conversion
Agent;

         (c)      that the 2023 Notes called for redemption may be converted at
any time before the close of business on the Business Day immediately preceding
the redemption date; and

         (d)      that Holders who wish to convert 2023 Notes must comply with
the procedures provided in the 2023 Notes.

                                       53
<PAGE>

         SECTION 13.05. Effect of Notice of Redemption. Once notice of
redemption is mailed, 2023 Notes called for redemption become due and payable on
the redemption date and at the Redemption Price, except for 2023 Notes that are
converted in accordance with the provisions of Article VI hereof and the
provisions of the 2023 Notes. Upon presentation and surrender to the Paying
Agent, 2023 Notes called for redemption shall be paid at the Redemption Price.

         SECTION 13.06. Deposit of Redemption Price. On or before 10:00 a.m.
(New York City time) on the redemption date, the Issuer shall deposit with the
Paying Agent (or if the Issuer or an Affiliate of the Issuer is acting as the
Paying Agent, shall segregate and hold in trust) an amount of money sufficient
to pay the aggregate Redemption Price of all the 2023 Notes to be redeemed on
that date other than the 2023 Notes or portions thereof called for redemption
which on or prior thereto have been delivered by the Issuer to the Security
Registrar for cancellation or have been converted. The Trustee and Paying Agent
shall, as promptly as practicable, return to the Issuer any money not required
for that purpose because of conversion of the 2023 Notes in accordance with the
provisions of Article VI hereof. If such money is then held by the Issuer or a
Subsidiary in trust and is not required for such purpose, it shall be discharged
from such trust.

                                   TESTIMONIUM

         This Thirteenth Supplemental Indenture may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but
all such counterparts shall together constitute but one and the same instrument.

different issue date, issue price and bearing interest from the last Interest
Payment Date to which interest has been paid or duly provided for on the 2010
Notes, and, if no interest has been paid, from July 17, 2003), may also be
issued by the Issuer pursuant to the Indenture without the consent of the
existing Holders of the 2010 Notes. Such additional Securities shall be part of
the same series as the 2010 Notes. The Stated Maturity of the 2010 Notes is
August 1, 2010; the principal amount of the 2010 Notes shall be payable on such
date unless the 2010 Notes are earlier redeemed or purchased in accordance with
the terms of the Indenture.

         (b)      The 2010 Notes will bear interest from the Original Issue
Date, or from the most recent date to which interest has been paid or duly
provided for, at the rate of 7.75% per annum stated therein until the principal
thereof is paid or made available for payment. Interest will be payable
semiannually on each Interest Payment Date and at Maturity, as provided in the
form of the 2010 Note in Section 2.03 hereof.

         (c)      The Record Date referred to in Section 2.3(f)(4) of the
Indenture for the payment of the interest on any 2010 Note payable on any
Interest Payment Date (other than at Maturity) shall be the 15th day preceding
the relevant Interest Payment Date (whether or not a Business Day) except that
the Record Date for interest payable at Maturity shall be the date of Maturity.

         (d)      The payment of the principal of, premium (if any) and interest
on the 2010 Notes shall not be secured by a security interest in any property.

         (e)      The 2010 Notes shall be redeemable at the option of the
Issuer, in whole or in part, at any time and from time to time, or not less than
30 days notice at a redemption price equal to 100% of the principal amount of
such 2010 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. In no event will the redemption price ever be less than 100% of
the principal amount of the 2010 Notes plus accrued interest to the redemption
date. The 2010 Notes shall be purchased by the Issuer at the option of the
Holders thereof as provided in Article III hereof.

         (f)      The 2010 Notes shall not be convertible.

         (g)      The 2010 Notes will not be subordinated to the payment of
Senior Debt.

         (h)      The Issuer will not pay any additional amounts on the 2010
Notes held by a Person who is not a U.S. person (as defined in Regulation S) in
respect of any tax, assessment or government charge withheld or deducted.

         (i)      The events specified in Events of Default with respect to the
2010 Notes shall include the events specified in Article V of this Fourteenth
Supplemental Indenture. In addition to the covenants set forth in Article Three
of the Original Indenture, the Holders of the 2010 Notes shall have the benefit
of the covenants of the Issuer set forth in this Fourteenth Supplemental
Indenture.

         SECTION 2.02. Forms Generally. The 2010 Notes and Trustee's
certificates of authentication shall be in substantially the form set forth in
this Article II, with such appropriate insertions, omissions, substitutions and
other variations as are required or permitted by the Indenture, and may have
such letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined by the
officers executing such 2010 Notes, as evidenced by their execution thereof.

steel engraved borders or may be produced in any other manner, all as determined

         CMS Energy Corporation, a corporation duly organized and existing under
the laws of the State of Michigan (herein called the "Issuer" or "Company",
which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to CEDE & Co., or
registered assigns, the principal sum of Three Hundred Million Dollars on August
1, 2010 ("Maturity") and to pay interest thereon from July 17, 2003 (the
"Original Issue Date") or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually in arrears on
February 1 and August 1 in each year, commencing on February 1, 2004 (each an
"Interest Payment Date") to the Persons in whose names the 2010 Notes are
registered at the close of business on the 15th day preceding the relevant
Interest Payment Date (each a "Record Date"), and at Maturity, at the rate of
7.75% per annum, until the principal hereof is paid or made available for
payment. The amount of interest payable on any Interest Payment Date shall be
computed on the basis of a 360-day year of twelve 30-day months. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such Indenture, be paid to the Person in whose name this

business on the Record Date for such interest, which shall be the 15th day
preceding the relevant Interest Payment Date (whether or not a Business Day)

of Maturity. Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Record Date and may either
be paid to the Person in whose name this 2010 Note (or one or more Predecessor
2010 Notes) is registered at the close of business on a subsequent Record Date
(which shall be not less than five Business Days prior to the date of payment of
such defaulted interest) for the payment of such defaulted interest to be fixed
by the Trustee, notice whereof shall be given to Holders of 2010 Notes not less
than 15 days preceding such subsequent Record Date.

to purchase by the Issuer at the option of the Holder as specified on the
reverse of this 2010 Note.

on this 2010 Note will be made at the office or agency of the Issuer maintained
for that purpose in New York, New York (the "Place of Payment"), in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the
option of the Issuer payment of interest (other than interest payable at
Maturity) may be made by check mailed to the address of

         SECTION 2.04. Form of Reverse of 2010 Note.

         This 7.75% Senior Note due 2010 is one of a duly authorized issue of
securities of the Issuer (herein called the "2010 Notes"), issued and to be
issued under an Indenture, dated as of September 15, 1992, as supplemented by
certain supplemental indentures, including the Fourteenth Supplemental
Indenture, dated as of July 17, 2003 (herein collectively referred to as the
"Indenture"), between the Issuer and Bank One Trust Company, N.A., a national
banking association (successor to 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, and the
Holders of the 2010 Notes and of the terms upon which the 2010 Notes are, and
are to be, authenticated and delivered. This 2010 Note is one of the series
designated on the face hereof, issued in an initial aggregate principal amount
of $300,000,000. Additional Securities, without limitation as to amount, having
substantially the same terms as the 2010 Notes (except a different issue date,
issue price and bearing interest from the last Interest Payment Date to

                                       16
<PAGE>

which interest has been paid or duly provided for on the 2010 Notes, and, if no
interest has been paid, from July 17, 2003), may also be issued by the Issuer
pursuant to the Indenture without the consent of the existing Holders of the
2010 Notes. Such additional Securities shall be part of the same series as the
2010 Notes.

         The 2010 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 2010 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 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 2010 Notes plus accrued interest to the redemption date.

         The following definitions are used to determine the Applicable Premium:

         "Applicable Premium" means, with respect to a 2010 Note (or portion
thereof) being redeemed at any time, the excess of (A) the present value at such
time of the principal amount of such 2010 Note (or portion thereof) being
redeemed plus all interest payments due on such 2010 Note (or portion thereof),
which present value shall be computed using a discount rate equal to the
Treasury Rate plus 50 basis points, over (B) the principal amount of such 2010
Note (or portion thereof) being redeemed at such time. For purposes of this
definition, the present values of the 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 redemption
date or, in the case of defeasance, prior to the date of deposit (or, if such
Statistical Release is no longer published, any publicly available source of
similar market data)) most nearly equal to the then remaining average life to
stated maturity of the 2010 Notes; provided, however, that if the average life
to stated maturity of the 2010 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.

         The interest rate borne by the Registrable Securities will be increased
by 0.25% per annum upon the occurrence of a Registration Default, which rate
will increase by an additional 0.25% per annum if such Registration Default has
not been cured within 90 days after the occurrence thereof and will continue to
increase by 0.25% at the beginning of each subsequent 90-day period until all
Registration Defaults have been cured

                                       17
<PAGE>

("Additional Amounts"); provided, that the aggregate amount of any such increase
in the interest rate on the Registrable Securities shall in no event exceed
0.50% per annum. All accrued Additional Amounts shall be paid to Holders of
Registrable Securities in the same manner and at the same time as regular
payments of interest on the Registrable Securities. Following the cure of all
Registration Defaults, the accrual of Additional Amounts shall cease and the
interest rate on the Registrable Securities will revert to 7.75% per annum.

         In the event of redemption of this 2010 Note in part only, a new 2010
Note 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 Issuer shall notify the Holder of
this 2010 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 2010
Note at a Change in Control Purchase Price equal to 101% of the principal amount
of this 2010 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 2010 Note, a new 2010 Note or 2010
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 2010 Note shall occur and
be continuing, the principal of this 2010 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,
repurchase date, Stated Maturity or Maturity of any 2010 Note shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of the Indenture or this 2010 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 Trustee and the Paying Agent shall return to the Issuer upon
written request any money or property held by them for the payment of any amount
with respect to the 2010 Notes that remains unclaimed for two years, provided,
however, that the Trustee or such Paying Agent, before being required to make
any such return, shall at the expense of the Issuer cause to be published once
in a newspaper of general circulation in The City of New York or mail to each
such Holder notice that such money or property remains unclaimed and that, after
a date specified therein, which shall not be less than 30 days from the date of
such publication or mailing, any unclaimed money or property then remaining
shall be returned to the Issuer. After return to the Issuer, Holders entitled to

                                       18
<PAGE>

the money or property must look to the Issuer for payment as general creditors
unless an applicable abandoned property law designates another Person.

         The Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this 2010 Note or (ii) certain restrictive covenants and
Events of Default with respect to this 2010 Note, in each case upon compliance
with certain conditions set forth therein.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of all outstanding 2010 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 2010 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 enforcement of payment of the principal of (and premium, if any)
or any interest on this 2010 Note on or after the respective due dates expressed
herein.

         No reference herein to the Indenture and no provision of this 2010 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 2010 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 2010 Note is registrable in the Security
Register, upon surrender of this 2010 Note for registration of transfer at the
office or agency of the Issuer in any place

                                       19
<PAGE>

where the principal of and any premium and interest on this 2010 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 2010 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 2010 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, 2010 Notes are
exchangeable for a like aggregate principal amount of 2010 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.

         The Issuer shall not be required to (i) issue, exchange or register the
transfer of this 2010 Note for a period of 15 days next preceding the mailing of
the notice of redemption of 2010 Notes or (ii) exchange or register the transfer
of any 2010 Note or any portion thereof selected, called or being called for
redemption, except in the case of any 2010 Note to be redeemed in part, the
portion thereof not so to be redeemed.

         Prior to due presentment of this 2010 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 2010 Note is registered as the owner hereof
for all purposes, whether or not this 2010 Note be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

         All terms used in this 2010 Note without definition which are defined
in the Indenture shall have the meanings assigned to them in the Indenture.

         SECTION 2.05. Form of Trustee's Certificate of Authentication. The

                                CHANGE IN CONTROL

         SECTION 3.01. Change in Control. Upon the occurrence of a Change in
Control (the effective date of such Change in Control being the "Change in
Control Date"), each Holder of a 2010 Note shall have the right to require that
the Issuer repurchase (a "Required Repurchase") all or any part of such Holder's
2010 Note at a repurchase price payable in cash equal to 101% of the principal
amount of such 2010 Note plus accrued interest to the Purchase Date (the "Change

         (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 2010 Notes at the Change in
                  Control Purchase Price;

                  (ii)     the Change in Control Purchase Price;

                  (iii)    the date on which any Required Repurchase shall be
                  made (which shall be no earlier than 60 days nor later than 90
                  days from the date such notice is mailed) (the "Purchase
                  Date");

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

                  (v)      the procedures that Holders must follow to cause the
                  2010 Notes to be repurchased, which shall be consistent with
                  this Section 3.01 and the Indenture.

         (b)      Holders electing to have a 2010 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 Chicago, Illinois, 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 2010 Notes to be
repurchased, which portion must be $1,000 or an integral multiple thereof; (ii)
that such 2010 Notes are to be repurchased by the Issuer pursuant to the change
in control provisions of the Indenture; and (iii) unless the 2010 Notes are
represented by one or more Global Notes, the certificate numbers of the 2010
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 2010 Notes
as to which the withdrawal notice relates and the

                                       21
<PAGE>

principal amount of such 2010 Notes, if any, which remains subject to a Change
in Control Purchase Notice.

         If a 2010 Note is represented by a Global Note (as described in Article
VI hereof), the Depositary or its nominee will be the Holder of such 2010 Note
and therefore will be the only entity that can elect a Required Repurchase of
such 2010 Note. To obtain repayment pursuant to this Section 3.01 with respect
to such 2010 Note, the beneficial owner of such 2010 Note must provide to the
broker or other entity through which it holds the beneficial interest in such
2010 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 3.01. Such broker or other entity will
provide to the Paying Agent (i) the Change in Control Purchase Notice received
from such beneficial owner and (ii) a certificate satisfactory to the 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 in Control Purchase Price for a 2010
Note for which a Change in Control Purchase Notice has been delivered and not
withdrawn is conditioned (except in the case of a 2010 Note represented by one
or more Global Notes) upon delivery of such 2010 Note (together with necessary
endorsements) to the Paying Agent at its office in Chicago, Illinois, 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 in Control Purchase
Price for such 2010 Note will be made promptly following the later of the
Purchase Date or the time of delivery of such 2010 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 2010 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 in Control Purchase Price upon delivery of the 2010
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
applicable in connection with any offer by the Issuer to repurchase 2010 Notes
at the option of Holders upon a Change in Control.

         (e)      No 2010 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 2010 Notes).

                         WITH RESPECT TO THE 2010 NOTES

         SECTION 4.01. Existence. So long as any of the 2010 Notes are

         (a)      So long as any of the 2010 Notes are outstanding, the Issuer
shall not create, incur, assume or suffer to 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 4.02 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 2010 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:

         (i)      Liens for taxes, assessments or governmental charges or levies
         to the extent not past due;

         (ii)     pledges or deposits to secure (A) obligations under workmen's

         are not overdue or which have been fully bonded and are being contested
         in good faith;

         (iv)     purchase money Liens upon or in property acquired and held by
         the Issuer in the ordinary course of business to secure the purchase
         price of such property or to secure Indebtedness incurred solely for
         the purpose of financing the acquisition of any such property to be
         subject to such Liens, or Liens existing on any such property at the
         time of acquisition, or extensions, renewals or replacements of any of
         the foregoing for the same or a lesser amount, provided that no such
         Lien shall extend to or cover any property other than the property
         being acquired and no such extension, renewal or replacement shall
         extend to or cover property not theretofore subject to the Lien being
         extended, renewed or replaced, and provided, further, that the
         aggregate principal amount of the Indebtedness at any one time
         outstanding secured by Liens permitted by this clause (iv) shall not
         exceed $10,000,000; and

                                       23

         this Section 4.02 securing Indebtedness of the Issuer; provided that on
         the date such Liens are created, and after giving effect to such
         Indebtedness, the aggregate principal amount at maturity of all of the
         secured Indebtedness of the Issuer at such date shall not exceed 5% of
         Consolidated Net Tangible Assets at such date.

         SECTION 4.03. Limitation on Consolidation, Merger, Sale or Conveyance.
So long as any of the 2010 Notes are outstanding and until the 2010 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 Original 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
(a) 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 (b) after giving effect to
such transaction, the surviving entity would be entitled to incur at least one

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 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

<PAGE>

         (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 Section

         Supplemental Indenture, as set forth on Schedule 4.04(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

         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 2010 Notes, the Indebtedness is
         subordinated to the 2010 Notes in right of payment;

         (3)      Indebtedness of the Issuer owed to and held by a Subsidiary
         and Indebtedness of a Subsidiary owed to and held by the Issuer;
         provided, however, 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
         Section 4.04(b) 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

         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 or
         refinanced is subordinated to the 2010 Notes, the Indebtedness so
         issued is subordinated to the 2010 Notes in right of payment;

         develop, improve, construct or to provide working capital for a gas,
         oil or electric generation, exploration, production, distribution,
         storage or transmission facility and related assets, provided that such
         Indebtedness is without recourse to any assets of the Issuer,
         Consumers, Enterprises, CMS Generation, CMS Electric and Gas, CMS Gas
         Transmission, CMS MST or any other Designated Enterprises Subsidiary;

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

         SECTION 4.05. Limitation on Restricted Payments.

         (a)      So long as the 2010 Notes are outstanding and until the 2010
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

                                       26
<PAGE>

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 herein
referred to as a "Restricted Payment") if at the time the Issuer or such
Subsidiary makes such Restricted Payment:

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

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

                  (A)      $100,000,000;

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

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

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

         (b)      The provisions of Section 4.05(a) hereof shall not prohibit:

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

                  (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;

                                       27
<PAGE>

                  (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 4.05; 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 2010
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 2010 Notes, (ii) invest an equal amount not so used in
clause (i) in property or assets of related business within 24 months after the
date of the Asset Sale (the "Application Period") or (iii) apply such excess Net
Cash Proceeds not so used in clause (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 2010 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 2010 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 2010 Notes from
Holders pursuant to clause (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 2010 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.

         SECTION 5.03. Additional Events of Default. Solely for the purpose of
determining Events of Default with respect to the 2010 Notes, an Event of
Default shall also include the following:

         (i)      default in the payment of any interest upon any 2010 Note,
         including Additional Amounts, if any, when it becomes due and payable,
         and continuance of such default for 30 days;

         (ii)     default in the Issuer's obligation to redeem the 2010 Notes
         after exercising its redemption option pursuant to this Fourteenth
         Supplemental Indenture; and

         (iii)    default in the Issuer's obligation to purchase 2010 Notes upon
         the occurrence of a Change in Control in accordance with the terms of
         Article III hereof.

                                   ARTICLE VI

                                  GLOBAL NOTES

         The 2010 Notes will be issued initially in the form of Global Notes.
"Global Note" means a registered 2010 Note evidencing one or more 2010 Notes
issued to a depositary (the "Depositary") or its nominee, in accordance with
this Article VI and bearing the legend prescribed in this Article VI. One or
more Global Notes will represent all 2010 Notes. The Issuer shall execute and
the Trustee shall, in accordance with this Article VI and the Issuer Order with
respect to the 2010 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 2010 Notes to
be represented by such Global Note or Global Notes, (ii) shall be registered in
the name of the Depositary for such Global Note or Global 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 2010 Note is presented
by an authorized representative of the Depositary to the Issuer or its agent for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of a nominee of the Depositary or in such other name as
is requested by an authorized representative of the Depositary (and any payment
is made to such nominee of the Depositary or to such other entity as is
requested by an authorized representative of the Depositary), 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 Original Indenture, unless and until
it is exchanged in whole or in part for 2010 Notes in definitive form, a Global
Note representing one or more 2010 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

                                       29
<PAGE>

nominee to a successor Depositary for 2010 Notes or a nominee of such successor
Depositary.

         If at any time the Depositary for the 2010 Notes is unwilling or unable
to continue as Depositary for the 2010 Notes, the Issuer shall appoint a
successor Depositary with respect to the 2010 Notes. If a successor Depositary
for the 2010 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 2010 Notes, will authenticate and deliver 2010 Notes in definitive
form in an aggregate principal amount equal to the principal amount of the
Global Note or Global Notes representing such 2010 Notes in exchange for such
Global Note or Global Notes.

         The Issuer may at any time and in its sole discretion determine that
the 2010 Notes issued in the form of one or more Global Notes shall no longer be
represented by such Global Note or Global Notes. In such event the Issuer will
execute, and the Trustee, upon receipt of an Issuer Order for the authentication
and delivery of definitive 2010 Notes, will authenticate and deliver 2010 Notes
in definitive form in an aggregate principal amount equal to the principal
amount of the Global Note or Global Notes representing such 2010 Notes in
exchange for such Global Note or Global Notes.

         The Depositary for such 2010 Notes may surrender a Global Note or
Global Notes for such 2010 Notes in exchange in whole or in part for 2010 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:

         (i)      to each Person specified by such Depositary a new 2010 Note or
         2010 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 2010
         Notes in definitive form delivered to Holders thereof.

         In any exchange provided for in this Article VI, the Issuer will
execute and the Trustee will authenticate and deliver 2010 Notes in definitive
registered form in authorized denominations.

         Upon the exchange of a Global Note for 2010 Notes in definitive form,
such Global Note shall be cancelled by the Trustee. 2010 Notes in definitive
form issued in exchange for a Global Note pursuant to this Article VI shall be
registered in such names

                                       30
<PAGE>

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
2010 Notes to the Persons in whose names such 2010 Notes are so registered.

                                   ARTICLE VII

                                   DEFEASANCE

         All of the provisions of Article Ten of the Original Indenture shall be
applicable to the 2010 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 under Article IV of this Fourteenth Supplemental Indenture with
respect to the 2010 Notes.

                                  ARTICLE VIII
                             SUPPLEMENTAL INDENTURES

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

                                   ARTICLE IX
                             MODIFICATION AND WAIVER

         In addition to those matters set forth in Section 8.2 of the Original
Indenture (including the terms and conditions of the 2010 Notes set forth
herein), with respect to the 2010 Notes, no amendment or supplemental indenture
to the Indenture shall, without the consent of the Holder of each 2010 Note
affected thereby:

         (a)      reduce the redemption price or Change in Control Purchase
Price of the 2010 Notes;

         (b)      change the terms applicable to redemption or purchase of the
2010 Notes in a manner adverse to the Holder; or

         (c)      alter the manner of calculation or rate of Additional Amounts
payable on any 2010 Note or extend the time for payment of any such amount.

         In addition, with respect to the 2010 Notes, notwithstanding Section
5.10 of the Original Indenture, approval of the Holders of each outstanding 2010
Note shall be required to waive any default by the Issuer in any payment of the
redemption price or Change in Control Purchase Price with respect to any 2010
Notes.

                                       31
<PAGE>

The reference to "interest" in Section 5.10(i) of the Original Indenture shall
include Additional Amounts, if any.

                                   TESTIMONIUM

         This Fourteenth Supplemental Indenture may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but
all such counterparts shall together constitute but one and the same instrument.

                                       32

         IN WITNESS WHEREOF, the parties hereto have caused this Fourteenth
Supplemental Indenture to be duly executed and their respective corporate seals
