SECTION 2.04. Form of Reverse of 2024 Note.

This 2.875% Convertible Senior Note due 2024 is one of a duly authorized issue of securities
of the Issuer (herein called the “2024 Notes"), issued and to be issued under an Indenture, dated
as of September 15, 1992, as supplemented by certain supplemental indentures, including the
Seventeenth Supplemental Indenture, dated as of December 13, 2004 (herein collectively referred to
as the “Indenture"), between the Issuer and J.P. Morgan Trust Company, N.A., a national banking
association (ultimate 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 2024 Notes and of the terms upon which the 2024 Notes are, and are to be,
authenticated and delivered. This 2024 Note is one of the series designated on the face hereof,
issued in an initial aggregate principal amount of $287,500,000. Additional Securities, without
limitation as to amount, having substantially the same terms as the 2024 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 2024 Notes, and, if no interest has been paid, from
December 13, 2004), may also be issued by the Issuer pursuant to the Indenture without the consent
of the existing Holders of the 2024 Notes. Such additional Securities shall be part of the same
series as the 2024 Notes.

Holders of 2024 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
2024 Notes at any time after the close of business on such Record Date. 2024 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 2024 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 2024
Notes to the extent of such overdue interest.

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 2024
Note) or if interest due hereon or any portion of such interest is not paid when due in accordance
with the terms of this 2024 Note, then in each such case the overdue amount shall bear interest at
the rate of 2.875% 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.

In the event of redemption of this 2024 Note in part only, a new 2024 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 2024 Notes. The 2024 Notes are redeemable for cash or check in
whole, or in part, at any time on or after December 7, 2011 at the option of the Issuer at a
redemption price (“Redemption Price”) equal to 100% of the principal amount of the 2024 Notes to be
redeemed plus any accrued and unpaid interest 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 2024 Notes to be redeemed at the Holder’s
registered address. If money sufficient to pay the Redemption Price of all 2024 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, if any, shall cease to accrue on
such 2024 Notes or portions thereof. 2024 Notes in denominations larger than $1,000 principal
amount may be redeemed in part but only in integral multiples of $1,000 principal amount.

Subject to the terms and conditions of the Indenture, a Holder shall have the option to
require the Issuer to purchase the 2024 Notes held by such Holder on December 1, 2011, December 1,
2014 and December 1, 2019 (each, a “Purchase Date”) at a purchase price (the “Purchase Price”)
equal to 100% of the principal amount of the 2024 Notes to be purchased plus any accrued and unpaid
interest 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 2024 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. 2024
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 December 1, 2011, 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 2024 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 2024 Notes purchased
plus accrued and unpaid interest 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 2024 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 shall cease to accrue on such 2024 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 2024 Notes into
cash and shares of Common Stock on or before the close of business on December 1, 2024 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;

(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
2024 Notes (as determined following a request by a Holder of the 2024 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 2024 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 2024 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 2024 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 2024 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 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 2024 Note into cash and shares of Common
Stock will be changed into a right to convert a 2024 Note into the kind and amount of cash,
securities or other property which the Holder would have received if the Holder had converted its
2024 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 2024 Notes as described in the Indenture.

2024 Notes in respect of which a Holder has delivered a notice of exercise of the option to
require the Issuer to purchase such 2024 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 approximately 67.7966 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 2024 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
2024 Notes at any time after the close of business on such Record Date. 2024 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 2024 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 2024
Notes to the extent of such overdue interest.

To convert the 2024 Notes a Holder must (i) complete and manually sign the irrevocable
conversion notice on the back of the 2024 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 2024 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 2024 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 on the
Common Stock except as provided in the Indenture. On conversion of the 2024 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 cash and shares of Common Stock (together with any cash
payment in lieu of fractional shares) in exchange for the portion of the 2024 Notes being converted
pursuant to the terms hereof; and the Fair Market Value of any 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 2024 Notes being converted
pursuant to the provisions hereof.

If an Event of Default with respect to this 2024 Note shall occur and be continuing, the
principal of this 2024 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 2024 Note shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of the Indenture or this 2024 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 2024 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 2024 Note or (ii) certain restrictive covenants and Events of Default with respect to this
2024 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 2024 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 2024 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 2024 Note on or after the
respective due dates expressed herein.

No reference herein to the Indenture and no provision of this 2024 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 2024 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

principal of and any premium and interest on this 2024 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 2024 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 2024 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, 2024 Notes are exchangeable for a like aggregate principal amount of 2024 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 2024 Note for a period of 15 days next preceding

Note is registered as the owner hereof for all purposes, whether or not this 2024 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 2024 Notes.
These calculations include, but are not limited to, determination of the market prices for the
Common Stock, the Conversion Value, the Principal Return, the Net Share Amount, accrued interest
payable on the 2024 Notes and the Conversion Price of the 2024 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 2024 Note without definition which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

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 December 1, 2011, each Holder shall have the
right, at such Holder’s option, to require the Issuer to purchase any or all of such Holder’s 2024
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 2024 Notes shall be repurchased in integral multiples of $1,000 of the principal amount. The
Issuer shall purchase such 2024 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, if any,
to the Fundamental Change Purchase Date. No 2024 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 2024 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 2024 Note to be so purchased at the option of the
Holder, the Paying Agent must receive such 2024 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 2024 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 2024 Notes which the Holder shall deliver to
be purchased, which portion must be $1,000 in principal amount or an integral multiple
thereof; and

(c) that such 2024 Notes shall be purchased as of the Fundamental Change Purchase Date
pursuant to the terms and conditions specified in the 2024 Notes and in this Seventeenth
Supplemental Indenture.

SECTION 3.04. Procedures. The Issuer shall purchase from a Holder, pursuant to this Article
III, 2024 Notes if the principal amount of such 2024 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 2024 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 2024 Notes to be purchased pursuant to this
Article III. Payment by the Paying Agent of the Fundamental Change Purchase Price for such 2024
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 2024 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 2024 Notes on the Business Day following the Fundamental Change Purchase Date, then,
on and after such date, such 2024 Notes shall cease to be outstanding and interest on such 2024
Notes shall cease to accrue, whether or not book-entry transfer of such 2024 Notes is made or such
2024 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 2024 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. 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 2024 Notes for redemption shall be determined by the Issuer, whose determination shall be final
and binding.

ARTICLE VI

CONVERSION OF 2024 NOTES

SECTION 6.01. Right to Convert. A Holder may convert its 2024 Notes for cash and shares of
Common Stock at any time during which the conditions stated in the 2024 Notes are met. The amount
of cash and number of shares of Common Stock issuable upon conversion of a 2024 Note per $1,000
principal amount (the “Conversion Rate”) shall be that set forth in Section 6.13 hereof, subject to
adjustment as herein set forth. The initial Conversion Rate is approximately 67.7966 shares of
Common Stock issuable upon conversion of a 2024 Note per $1,000 principal amount.

A Holder may convert a portion of the principal amount of 2024 Notes if the portion is $1,000
or a multiple of $1,000.

SECTION 6.02. Conversion Procedures. To convert 2024 Notes, a Holder must satisfy the
requirements in this Section 6.02 and in the 2024 Notes. The date on which the Holder satisfies
all those requirements is the conversion date (the “Conversion Date”). Subject to the procedures
set forth in Section 6.13 hereof, as soon as practicable, but in no event later than the fifth
Business Day following the Conversion Date, the Issuer shall deliver the Conversion Value in cash
and deliver the Common Stock by either of the following methods: (i) update the global security
representing the shares of Common Stock to record the Holder’s interests in the Common Stock; or
(ii) deliver to the Holder, through the Conversion Agent, a certificate for the number of full
shares of Common Stock representing Net Shares, if any, together with, in either case, 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 2024 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 cash and 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 cash and 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 2024 Notes shall have been surrendered for conversion, as if the stock
transfer books of the Issuer had not been closed. Upon conversion of 2024 Notes, such Person shall
no longer be a Holder of such 2024 Notes.

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 2024 Notes, delivery of the Principal Return and the Net Shares (together
with the cash or check payment, if any, in lieu of fractional shares) will be deemed to satisfy the
Issuer’s obligation to pay the principal amount of the converted 2024 Notes as well as accrued
interest with respect to the converted 2024 Notes. Accrued interest on the 2024 Notes shall be
deemed canceled, extinguished or forfeited, rather than paid in full.

If a Holder converts more than one 2024 Note at the same time, the amount of cash and number
of shares of Common Stock issuable upon the conversion shall be based on the total principal amount
of the 2024 Notes converted.

Upon surrender of a 2024 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 2024 Note
in an authorized denomination equal in principal amount to the unconverted portion of the 2024 Note
surrendered.

If the last day on which 2024 Notes may be converted is a legal holiday in a place where a
Conversion Agent is located, the 2024 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 2024 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 2024 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 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 2024 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 2024
Notes.

All shares of Common Stock delivered upon conversion of the 2024 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 2024 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 2024 Notes thereafter surrendered for conversion shall be entitled to
receive the cash and 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 2024 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
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 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 cash and 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 2024 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 applicable 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 declare a cash dividend or cash distribution to all or
substantially all of the holders of Common Stock, the Conversion Rate shall be increased so
that the applicable Conversion Rate shall equal the price determined by multiplying the
Conversion Rate in effect immediately prior to the record date for such dividend or
distribution by a fraction, (i) the numerator of which shall be the average of the Last
Reported Sale Price of the Common Stock for the five consecutive Trading Days ending on the
Trading Day immediately preceding the record date for such dividend or distribution (the
“Pre-Dividend Sale Price”) and (ii) the denominator of which shall be the Pre-Dividend Sale
Price, minus the full amount of such cash dividend or cash distribution applicable to one
share of Common Stock (the “Dividend Adjustment Amount”), with such adjustment to become
effective immediately after the record date for such dividend or distribution; provided that
if the denominator of the foregoing fraction is less than $1.00 (including a negative
amount), 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 cash and
Common Stock issuable upon such conversion, the amount of cash such Holder would have
received had such Holder converted its 2024 Note solely into Common Stock at the then
applicable Conversion Rate immediately prior to the record date for such cash dividend or
cash distribution. If such cash dividend or cash distribution is not so paid or made, the
applicable Conversion Rate shall again be adjusted to be the Conversion Rate that would then
be in effect if such dividend or distribution had not been declared.

(e) If a Holder elects to convert 2024 Notes in connection with a corporate transaction as
described in Section 2.04(e) hereof that occurs on or prior to December 1, 2011, that
constitutes a Fundamental Change (other than as described in clause (iv) of the definition
of Fundamental Change) and 10% or more of the Fair Market Value of the consideration for the
Common Stock (as determined by the Board of Directors, whose determination shall be
conclusive evidence of such Fair Market Value) in the corporate transaction consists of (i)
cash, (ii) other property or (iii) securities that are not traded or scheduled to be traded
immediately following such transaction on a U.S. national securities exchange or the Nasdaq
National Market, then the Conversion Rate for the 2024 Notes surrendered for conversion by
such Holder shall be adjusted so that such Holder will be entitled to receive cash and
 shares of Common Stock equal to the sum of (A) the Conversion Value and (B) the number of
additional shares of Common Stock (the “Additional Shares”) determined in the manner set
forth below, subject in each case to the Issuer’s payment elections as described in Section
6.13 hereof. For the avoidance of doubt, the adjustment provided for in this Section
6.06(e) shall only be made with respect to the 2024 Notes being converted in connection with
such Fundamental Change and shall not be effective as to any 2024 Notes not so converted.

The number of Additional Shares will be determined by reference to the table below,
based on the date on which such corporate transaction becomes effective (the “Effective
Date”) and the Share Price; provided that if the Share Price is between two Share Price
amounts in the table below or the Effective Date is between two Effective Dates in the table
below, the number of Additional Shares will be determined by a straight-line interpolation
between the number of Additional Shares set forth for the higher and lower Share Price
amounts and the two dates, as applicable, based on a 365-day year.

The Share Prices set forth in the first row of the table below (i.e., column headers)
will be adjusted as of any date on which the applicable Conversion Rate of the 2024 Notes is
adjusted pursuant to this Section 6.06. The adjusted Share Prices will equal the Share
Prices applicable immediately prior to such adjustment, multiplied by a fraction, the
numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to
the Share Price adjustment and the denominator of which is the Conversion Rate as so
adjusted.

The following table sets forth the hypothetical Share Price and number of Additional
Shares to be received per $1,000 principal amount of 2024 Notes:

The Share Prices and Additional Share amounts set forth above are based upon an
initial Conversion Rate per share of 67.7966 per $1,000 principal amount of 2024 Notes.

If the Share Price is equal to or in excess of $50.00 per share (subject to
adjustment), no Additional Shares will be issued upon conversion.

If the Share Price is less than $10.17 per share (subject to adjustment), no Additional
Shares will be issued upon conversion.

Notwithstanding the foregoing, any adjustment to the applicable Conversion Rate
relating to the issuance of Additional Shares as described in this Section 6.06(e) will not
exceed the Maximum Conversion Rate.

(f) Notwithstanding the foregoing, in the case of a Public Acquirer Change of Control, the
Issuer may, in lieu of increasing the applicable Conversion Rate by Additional Shares as
described in Section 6.06(e) hereof, elect to adjust the applicable Conversion Rate and the
related conversion obligation such that upon conversion the Issuer will deliver cash and a
number of shares of Public Acquirer Common Stock such that the Conversion Rate in effect
immediately before the Public Acquirer Change of Control shall be adjusted by a fraction:

(i) the numerator of which will be the average of the Last Reported Sale Price
of the Common Stock for the five consecutive Trading Days prior to but excluding the
effective date of such Public Acquirer Change of Control; and

(ii) the denominator of which will be the average of the Last Reported Sale
Price of the Public Acquirer Common Stock for the five consecutive Trading Days
commencing on the Trading Day next succeeding the effective date of such Public
Acquirer Change of Control.

A “Public Acquirer Change of Control” means any event described in Section 6.06(e)
hereof that would otherwise obligate the Issuer to increase the Conversion Rate as described
in Section 6.06(e) hereof and the acquirer (or any entity of which the acquirer is a
directly or indirectly wholly-owned Subsidiary and such entity provides a guarantee to the
2024 Notes) has a class of common stock traded on a U.S. national securities exchange or
quoted on the Nasdaq National Market or which will be so traded or quoted when issued or
exchanged in connection with such event (the ‘‘Public Acquirer Common Stock’’).

After the adjustment of the applicable Conversion Rate in connection with a Public
Acquirer Change of Control, the applicable Conversion Rate will be subject to further
similar adjustments in the event that any of the events described in this Section 6.06 occur
thereafter.

The Issuer is required to notify Holders of its election in writing of such
transaction, which notice shall be made five Business Days prior to the effective date of
such Public Acquirer Change of Control. In addition, the Holder can also, subject to certain
conditions, require the Company to repurchase all or a portion of its 2024 Notes as
described under Article III.

(g) 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 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.

(h) Upon conversion of the 2024 Notes, the Holders shall receive, in addition to the cash
and 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 2024 Notes
receive rights under such shareholder rights plans as described in the preceding sentence
upon conversion of their 2024 Notes, then no other adjustment pursuant to this Section 6.06
shall be made in connection with such shareholder rights plans.

(i) 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.

(j) Notwithstanding the foregoing, in no event shall the Conversion Rate exceed the maximum
conversion rate specified under this Section 6.06(j) (the “Maximum Conversion Rate”)
as a result of an adjustment pursuant to Sections 6.06(c), 6.06(d) and 6.06(e) hereof. The
Maximum Conversion Rate shall initially be 98.3284 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.

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 Seventeenth Supplemental Indenture;

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

(e) for accrued and unpaid interest; 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 2024 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 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 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 2024 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 2024 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 Conversion Value of 2024 Notes Tendered.

(a) Subject to certain exceptions described in Sections 2.04(b) and 2.04(e), Holders tendering
the 2024 Notes for conversion shall be entitled to receive, upon conversion of such 2024 Notes,
cash and shares of Common Stock, the value of which (the “Conversion Value”) shall be equal to the
product of:

(i) (A) the aggregate principal amount of 2024 Notes to be converted divided by 1,000
multiplied by (B) the then applicable Conversion Rate; and

(ii) the average of the Common Stock prices for the ten consecutive Trading Days
(appropriately adjusted to take into account the occurrence during such period of stock
splits, stock dividends and similar events) beginning on the second Trading Day immediately
following the day the 2024 Notes are tendered for conversion (the “Ten Day Average Closing
Stock Price”).

(b) Subject to certain exceptions described below and under Sections 2.04(b) and 2.04(e), the
Issuer shall deliver the Conversion Value to converting Holders as follows:

(i) an amount in cash (the “Principal Return”) equal to the lesser of (a) the
Conversion Value of the 2024 Notes to be converted and (b) the aggregate principal amount of
the 2024 Notes to be converted;

(ii) if the Conversion Value of the 2024 Notes to be converted is greater than the
Principal Return, an amount in whole shares (the “Net Shares”), determined as set forth
below, equal to such aggregate Conversion Value less the Principal Return (the “Net Share
Amount”); and

(iii) an amount paid in cash, determined as set forth below, in lieu of any fractional
 shares of Common Stock.

The number of Net Shares to be paid shall be determined by dividing the Net Share Amount by
the Ten Day Average Closing Stock Price. Holders of 2024 Notes will not receive fractional shares
upon conversion of 2024 Notes. In lieu of fractional shares, Holders will receive cash for the
value of the fractional shares, which cash payment shall be based on the Ten Day Average Closing
Stock Price.

The Conversion Value, Principal Return, number of Net Shares and Net Share Amount shall be
determined by the Issuer at the end of the ten consecutive Trading Day period beginning on the
second Trading Day immediately following the day the 2024 Notes are tendered for conversion (the
“Determination Date”).

The Issuer shall pay the Principal Return and cash for fractional shares and deliver the Net
Shares, if any, as promptly as practicable after the Determination Date, but in no event later than
five Business Days thereafter. Except as provided in Section 2.04, delivery of the Principal
Return, Net Shares and cash in lieu of fractional shares shall be deemed to satisfy the Issuer’s
obligation to pay the principal amount of a converted 2024 Note, including accrued but unpaid
interest thereon. Any accrued and unpaid interest payable on a converted 2024 Note shall be deemed
canceled, extinguished or forfeited rather than paid in full.

(c) Neither the Trustee nor the Conversion Agent has any duty to determine or calculate the
Conversion Value, Principal Return, number of Net Shares, the Net Share Amount or any other
computation required under this Section 6.13, all of which shall be determined by the Issuer (or
the Trustee, as the case may be) in accordance with the provisions of this Indenture, and the
Trustee and Conversion Agent shall not be under any responsibility to determine the correctness of
any such determinations and/or calculations and may conclusively rely on the correctness thereof.

SECTION 6.14. 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
2024 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 2024 Notes for the purpose of conversion or to comply with any of the
duties, responsibilities or covenants of the Issuer contained in this Section 6.14. 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 2024 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 6.15. 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
6.15 shall be done to evade the principle set forth in Section 6.06(j) 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 6.16. 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 6.17. 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 6.18. 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 6.19. Conversion Provisions. Pursuant to Section 2.3(f)(10) of the Original
Indenture, the obligation of the Issuer to permit the conversion of the 2024 Notes into Common
Stock and the terms and conditions upon which such conversion shall be effected set forth in this
Seventeenth 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.

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 2024 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:

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

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
2024 Notes are outstanding and until the 2024 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 2024 Notes are outstanding and until the 2024 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

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

(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.

(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

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

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;

(4) Indebtedness of the Issuer issued in exchange for, or the proceeds of which are
used to refund or refinance, Indebtedness of the Issuer issued in accordance with
Section 7.04(a) hereof, provided that (i) the principal amount (or accreted value in
the case of Indebtedness issued at a discount) of the Indebtedness so issued shall
not exceed the principal amount (or accreted value in the case of Indebtedness
issued at a discount) of, premium, if any, and accrued but unpaid interest on, the
Indebtedness so exchanged, refunded or refinanced and (ii) the Indebtedness so

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)

SECTION 7.05. Limitation on Restricted Payments.

(a) So long as the 2024 Notes are outstanding and until the 2024 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:

(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 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 2024 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 2024 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 2024 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 2024 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 2024 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 2024 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 2024 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 2024 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 2024 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 2024 Notes, an Event of Default shall also include the following:

(i) default in the payment of any interest upon any 2024 Note when it becomes due and payable, and
continuance of such default for 30 days;

(ii) default in the Issuer’s obligation to redeem the 2024 Notes after exercising its redemption

Change or the exercise by a Holder of its option to require the Issuer to repurchase such Holder’s
2024 Notes in accordance with the terms of Article III or Article IV hereof, as applicable.

ARTICLE IX

GLOBAL NOTES

The 2024 Notes will be issued initially in the form of Global Notes. “Global Note” means a
registered 2024 Note evidencing one or more 2024 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 2024 Notes. The Issuer shall execute and the
Trustee shall, in accordance with this Article IX and the Issuer Order with respect to the 2024
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 2024 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 2024 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 2024 Notes in definitive form, a Global Note representing one or more 2024
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 2024 Notes or a nominee of such
successor Depositary.

If at any time the Depositary for the 2024 Notes is unwilling or unable to continue as
Depositary for the 2024 Notes, the Issuer shall appoint a successor Depositary with respect to the
2024 Notes. If a successor Depositary for the 2024 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 2024 Notes, will authenticate and deliver 2024 Notes in
definitive form in an aggregate principal amount equal to the principal amount of the Global Note
or Global Notes representing such 2024 Notes in exchange for such Global Note or Global Notes.

The Issuer may at any time and in its sole discretion determine that the 2024 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 2024 Notes, will authenticate and deliver 2024 Notes
in definitive form in an aggregate principal amount equal to the principal amount of the Global
Note or Global Notes representing such 2024 Notes in exchange for such Global Note or Global Notes.

The Depositary for such 2024 Notes may surrender a Global Note or Global Notes for such 2024
Notes in exchange in whole or in part for 2024 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 2024 Note or 2024 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 2024 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 2024 Notes in definitive registered form in authorized denominations.

Upon the exchange of a Global Note for 2024 Notes in definitive form, such Global Note shall
be cancelled by the Trustee. 2024 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 2024 Notes to the Persons in whose names such 2024 Notes are so registered.

ARTICLE X

DEFEASANCE

All of the provisions of Article Ten of the Original Indenture shall be applicable to the 2024
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 Seventeenth Supplemental Indenture with respect to the
2024 Notes.

ARTICLE XI

SUPPLEMENTAL INDENTURES

This Seventeenth Supplemental Indenture is a supplement to the Original Indenture. As
supplemented by this Seventeenth Supplemental Indenture, the Original Indenture is in all respects
ratified, approved and confirmed, and the Original Indenture and this Seventeenth 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 2024 Notes set forth herein), with respect to the 2024 Notes, no
amendment or supplemental indenture to the Indenture shall, without the consent of the Holder of
each 2024 Note affected thereby:

(a) reduce the Redemption Price, Purchase Price or Fundamental Change Purchase Price of the 2024
Notes; or

(b) change the terms applicable to redemption or purchase of the 2024 Notes in a manner adverse to
the Holder.

In addition, with respect to the 2024 Notes, notwithstanding Section 5.10 of the Original
Indenture, approval of the Holders of each outstanding 2024 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 2024 Notes; or

(b) waive any default which constitutes a failure to convert any 2024 Note in accordance with its
terms and the terms of Article VI hereof.

ARTICLE XIII

OPTIONAL REDEMPTION OF THE 2024 NOTES

SECTION 13.01. Right to Redeem; Notice to Trustee, Paying Agent and Holders. On or after
December 7, 2011, the Issuer may, at its option, redeem the 2024 Notes in whole, or in part, at any
time in accordance with the provisions of the 2024 Notes. If the Issuer elects to redeem 2024
Notes pursuant to the provisions of the 2024 Notes, it shall notify in writing the Trustee, the
Paying Agent and each Holder of 2024 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 2024 Notes to Be Redeemed. If fewer than all of
the outstanding 2024 Notes are to be redeemed, the Trustee shall select the 2024 Notes to be
redeemed in principal amounts of $1,000 or integral multiples thereof. In the case that the
Trustee shall select the 2024 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 2024 Notes to Be Redeemed. If any 2024 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 2024 Notes so selected, the converted portion
of such 2024 Notes shall be deemed (so far as may be), solely for purposes of determining the
aggregate principal amount of 2024 Notes to be redeemed by the Issuer, to be the portion selected
for redemption. 2024 Notes which have been converted during a selection of 2024 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 2024 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 2024 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 2024 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 2024 Notes must comply with the procedures provided in
the 2024 Notes.

SECTION 13.05. Effect of Notice of Redemption. Once notice of redemption is mailed, 2024
Notes called for redemption become due and payable on the redemption date and at the Redemption
Price, except for 2024 Notes that are converted in accordance with the provisions of Article VI
hereof and the provisions of the 2024 Notes. Upon presentation and surrender to the Paying Agent,
2024 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 2024 Notes to be redeemed on
that date other than the 2024 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 2024 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 Seventeenth 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.

and interest on this bond shall be payable at the office or agency of the Company in the Borough of

States of America which at the time of payment is legal tender for public and private debts.

This bond is one of the bonds of a series designated as First Mortgage Bonds, 5.00% Series due
2015 (sometimes herein referred to as the “2015 Bonds” or the “Bonds”) issued and to be issued from
time to time under and in accordance with and secured by an indenture dated as of September 1,
1945, given by the Company (or its predecessor, Consumers Power Company, a Maine corporation) to
City Bank Farmers Trust Company (JPMorgan Chase Bank, N.A., successor) (hereinafter sometimes
referred to as the “Trustee”), together with indentures supplemental thereto, heretofore or
hereafter executed, to which indenture and indentures supplemental thereto (hereinafter referred to
collectively as the “Indenture”) reference is hereby made for a description of the property
mortgaged and pledged, the nature and extent of the security and the rights, duties and immunities
thereunder of the Trustee and the rights of the holders of said bonds and of the Trustee and of the
Company in respect of such security, and the limitations on such rights. By the terms of the
Indenture, the bonds to be secured thereby are issuable in series which may vary as to date,
amount, date of maturity, rate of interest and in other respects as provided in the Indenture.

The 2015 Bonds are redeemable upon notice given by mailing the same, postage prepaid, not less
than thirty days nor more than sixty days prior to the date fixed for redemption to each registered
holder of a bond to be redeemed (in whole or in part) at the last address of such holder appearing
on the registry books. Any or all of the bonds of this series may be redeemed by the Company, at
any time and from time to time prior to maturity, at a redemption price equal to the greater of (1)
100% of the principal amount of the Bonds and (2) the sum of the present values of the Remaining
Scheduled Payments (as defined below) of principal and interest on the Bonds discounted to the
redemption date semiannually (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate (as defined below), plus 15 basis points, plus in either case accrued interest on the
Bonds to the date of redemption.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the
semiannual equivalent yield to maturity of the Comparable Treasury Issue (as defined below),
assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price (as defined below) for such redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker (as defined below) as having a maturity comparable to the remaining
term of the Bonds to be redeemed that would be used, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Bonds.

“Independent Investment Banker” means either Morgan Stanley & Co. Incorporated or J.P. Morgan
Securities Inc. or, if such firms are unwilling or unable to select the Comparable Treasury Issues,
an independent banking institution of national standing selected by the Company.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the
bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) on the third business day preceding such redemption date, as set forth in the
daily statistical release (or any successor release) published by the Federal Reserve Bank of New
York and designated “H.15(519)” or (2) if such release (or any successor release) is not published
or does not contain such prices on such business day, (a) the average of the Reference Treasury
Dealer Quotations (as defined below) for such redemption date, after excluding the highest and
lowest of such Reference Treasury Dealer Quotations, or (b) if the Company obtains fewer than four
such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
(as defined below) and any redemption date, the average, as determined by the Company, of the bid
and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m.
on the third business day preceding such redemption date.

“Reference Treasury Dealer” means (1) each of Morgan Stanley & Co. Incorporated, J.P. Morgan
Securities Inc. and Citigroup Global Markets Inc. and their respective successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer
in New York City (a “Primary Treasury Dealer”), the Company shall replace that former dealer with
another Primary Treasury Dealer and (2) up to four other Primary Treasury Dealers selected by the
Company.

“Remaining Scheduled Payments” means, with respect to each Bond to be redeemed, the remaining
scheduled payments of the principal thereof and interest thereon that would be due after the
related redemption date but for such redemption; provided, however, that, if that redemption date
is prior to an interest payment date with respect to such Bond, the amount of the next succeeding
scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to
that redemption date.

In case of certain defaults as specified in the Indenture, the principal of this bond may be
declared or may become due and payable on the conditions, at the time, in the manner and with the
effect provided in the Indenture. The holders of certain specified percentages of the bonds at the
time outstanding, including in certain cases specified percentages of bonds of particular series,
may in certain cases, to the extent and as provided in the Indenture, waive certain defaults
thereunder and the consequences of such defaults.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of
the holders of not less than seventy-five per centum in principal amount of the bonds (exclusive of
bonds disqualified by reason of the Company’s interest therein) at the time outstanding, including,
if more than one series of bonds shall be at the time outstanding, not less than sixty per centum
in principal amount of each series affected, to effect, by an indenture supplemental to the
Indenture, modifications or alterations of the Indenture and of the rights and obligations of the
Company and the rights of the holders of the bonds and coupons; provided, however, that no such
modification or alteration shall be made without the written approval or consent of the holder
hereof which will (a) extend the maturity of this bond or reduce the rate or extend the time of
payment of interest hereon or reduce the amount of the principal hereof or reduce any premium
payable on the redemption hereof, (b) permit the creation of any lien, not otherwise permitted,
prior to or on a parity with the lien of the Indenture, or (c) reduce the percentage of the
principal amount of the bonds upon the approval or consent of the holders of which modifications or
alterations may be made as aforesaid.

The Company reserves the right, without any consent, vote or other action by holders of the
2015 Bonds or any other series created after the Sixty-eighth Supplemental Indenture to amend the
Indenture to reduce the percentage of the principal amount of bonds the holders of which are
required to approve any supplemental indenture (other than any supplemental indenture which is
subject to the proviso contained in the immediately preceding sentence) (a) from not less than
seventy-five per centum (including sixty per centum of each series affected) to not less than a
majority in principal amount of the bonds at the time outstanding or (b) in case fewer than all
series are affected, not less than a majority in principal amount of the bonds of all affected
series, voting together.

No recourse shall be had for the payment of the principal of or premium, if any, or interest
on this bond, or for any claim based hereon, or otherwise in respect hereof or of the Indenture, to
or against any incorporator, stockholder, director or officer, past, present or future, as such, of
the Company, or of any predecessor or successor company, either directly or through the Company, or
such predecessor or successor company, or otherwise, under any constitution or statute or rule of
law, or by the enforcement of any assessment or penalty, or otherwise, all such liability of
incorporators, stockholders, directors and officers, as such, being waived and released by the
holder and owner hereof by the acceptance of this bond and being likewise waived and released by
the terms of the Indenture.

and coupons when payable and the performance of and compliance with the covenants and conditions of
the Indenture and of any supplemental indenture, without any preference, distinction or priority as

actual authentication, delivery, issue, sale or negotiation thereof or for any other reason
whatsoever, except as otherwise expressly provided in the Indenture; and so that each and every
bond now or hereafter authenticated and delivered thereunder shall have the same lien, and so that

form thereof shall be substantially as hereinbefore set forth. The 2015 Bonds shall be issued in
the aggregate principal amount of $225,000,000, shall mature on March 15, 2015 and shall be issued
only as registered bonds without coupons in denominations of $1,000 and any multiple thereof. The
serial numbers of the 2015 Bonds shall be such as may be approved by any officer of the Company,
the execution thereof by any such officer either manually or by facsimile signature to be
conclusive evidence of such approval. The 2015 Bonds shall bear interest at the rate per annum,
until the principal thereof shall have become due and payable, specified in the title thereto,
payable semi-annually on March 15 and September 15 in each year. The principal of and the premium,
if any, and the interest on said bonds shall be payable in any coin or currency of the United
States of America which at the time of payment is legal tender for public and private debts, at the
office or agency of the Company in the City of New York, designated for that purpose.

	 	 	 
	SECTION 2.

2.01

	 	

Form of Bonds.
	
 
	 	 

The 2015 Bonds shall be issued initially in the form of one or more permanent Global Bonds in
definitive, fully registered form without interest coupons with the global securities legend (each,
a “Global Bond”), which shall be deposited on behalf of the purchasers of the Bonds represented
thereby with the Trustee, at its corporate trust office, as securities custodian (or with such
other securities custodian as the Depository (as defined below) may direct), and registered in the
name of the Depository or a nominee of the Depository, duly executed by the Company and
authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Global
Bonds may from time to time be increased or decreased by adjustments made on the records of the
Trustee and the Depository or its nominee as hereinafter provided. The Depositary for the Global
Bonds shall be The Depository Trust Company, a New York corporation, or its duly appointed
successor (the “Depository”). This Section 2.01 shall apply only to a Global Bond deposited with
or on behalf of the Depository.

The Company shall execute and the Trustee shall, in the case of each of the 2015 Bonds in
accordance with this Section 2.01, authenticate and deliver initially one or more Global Bonds that
(a) shall be registered in the name of the Depository or the nominee of the Depository and (b)
shall be delivered by the Trustee to the Depository or pursuant to the Depository’s instructions or
held by the Trustee as securities custodian.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under
this Supplemental Indenture with respect to any Global Bond held on their behalf by the Depository
or by the Trustee as the securities custodian or under such Global Bond, and the Company, the
Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depository as
the absolute owner of such Global Bond for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the Company from giving
effect to any written certification, proxy or other authorization furnished by the Depository or
impair, as between the Depository and its Agent Members, the operation of customary practices of
such Depository governing the exercise of the rights of a holder of a beneficial interest in any
Global Bond.

Except as provided in this Section 2.01, Section 2.02 or Section 2.03, owners of beneficial
interests in Global Bonds shall not be entitled to receive physical delivery of certificated Bonds.

2.02 Transfer and Exchange.

(a) Transfer and Exchange of Global Bonds.

(i) The transfer and exchange of Global Bonds or beneficial interests therein shall
be effected through the Depository, in accordance with this Supplemental Indenture
(including applicable restrictions on transfer set forth herein, if any) and the
procedures of the Depository therefor.

(ii) Notwithstanding any other provision of this Supplemental Indenture (other than
the provisions set forth in Section 2.03), a Global Bond may not be transferred as a whole
except by the Depository to a nominee of the Depository or by a nominee of the Depository
to the Depository or another nominee of the Depository or by the Depository or any such
nominee to a successor Depository or a nominee of such successor Depository.

(b) Cancellation or Adjustment of Global Bond. At such time as all beneficial
interests in a Global Bond have either been exchanged for certificated Bonds, redeemed, purchased
or canceled, such Global Bond shall be canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Bond is exchanged for certificated Bonds,
redeemed, purchased or canceled, the principal amount of Bonds represented by such Global Bond
shall be reduced and an adjustment shall be made on the books and records of the securities
custodian with respect to such Global Bond.

(c) Obligations with Respect to Transfers and Exchanges of Bonds.

(i) To permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate certificated Bonds and Global Bonds at the security
registrar’s request.

(ii) No service charge shall be made for registration of transfer or exchange, but
the Company may require payment of a sum sufficient to cover any transfer tax, assessments
or similar governmental charge payable in connection therewith.

(iii) Prior to the due presentation for registration of transfer of any Bond, the
Company, the Trustee, the paying agent or the security registrar may deem and treat the
person in whose name a Bond is registered as the absolute owner of such Bond for the
purpose of receiving payment of principal of and interest on such Bond and for all other
purposes whatsoever, whether or not such Bond is overdue, and none of the Company, the
Trustee, the paying agent or the security registrar shall be affected by notice to the
contrary.

(iv) All Bonds issued upon any transfer or exchange pursuant to the terms of the
Indenture shall evidence the same debt and shall be entitled to the same benefits under
the Indenture as the Bonds surrendered upon such transfer or exchange.

(d) No Obligation of Trustee.

(i) The Trustee (whether in its capacity as Trustee or otherwise) shall have no
responsibility or obligation to any beneficial owner of a Global Bond, Agent Member or
other person with respect to the accuracy of the records of the Depository or its nominee
or of any Agent Member, with respect to any ownership interest in the Bonds or with
respect to the delivery to any Agent Member, beneficial owner or other person (other than
the Depository) of any notice (including any notice of redemption) or the payment of any
amount, under or with respect to such Bonds. All notices and communications to be given
to the holders and all payments to be made to holders under the Bonds shall be given or
made only to or upon the order of the registered holders (which shall be the Depository or
its nominee in the case of a Global Bond). The rights of beneficial owners in any Global
Bond shall be exercised only through the Depository subject to the applicable rules and
procedures of the Depository. The Trustee may rely and shall be fully protected in
relying upon information furnished by the Depository with respect to its Agent Members and
any beneficial owners.

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as
to compliance with any restrictions on transfer imposed under this Supplemental Indenture
or under applicable law with respect to any transfer of any interest in any Bond
(including any transfers between or among Agent Members or beneficial owners in any Global
Bond) other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly required by, the
terms of the Indenture.

2.03 Certificated Bonds.

(a) A Global Bond deposited with the Depository or with the Trustee as securities custodian
pursuant to Section 2.01 shall be transferred to the beneficial owners thereof in the form of
certificated Bonds in an aggregate principal amount equal to the principal amount of such Global
Bond, in exchange for such Global Bond, only if such transfer complies with this Section 2.03 and
the conditions set forth in Article II of the Indenture.

(b) Any Global Bond that is transferable to the beneficial owners thereof pursuant to this
Section 2.03 shall be surrendered by the Depository to the Trustee at its corporate trust office to
be so transferred, in whole or from time to time in part, without charge, and the Trustee shall
authenticate and deliver, upon such transfer of each portion of such Global Bond, an equal
aggregate principal amount of certificated Bonds of authorized denominations. Any portion of a
Global Bond transferred pursuant to this Section 2.03 shall be executed, authenticated and
delivered only in denominations of $1,000 principal amount and any integral multiple thereof and
registered in such names as the Depository shall direct.

(c) Subject to the provisions of Section 2.03(b), the registered holder of a Global Bond shall
be entitled to grant proxies and otherwise authorize any person, including Agent Members and
persons that may hold interests through Agent Members, to take any action which a holder is
entitled to take under the Indenture or the Bonds.

SECTION 3. The 2015 Bonds are redeemable upon notice given by mailing the same, postage
prepaid, not less than thirty days nor more than sixty days prior to the date fixed for redemption
to each registered holder of a bond to be redeemed (in whole or in part) at the last address of
such holder appearing on the registry books. Any or all of the bonds of this series may be
redeemed by the Company, at any time and from time to time prior to maturity, at a redemption price
equal to the greater of (1) 100% of the principal amount of the Bonds and (2) the sum of the
present values of the Remaining Scheduled Payments (as defined below) of principal and interest on
the Bonds discounted to the redemption date semiannually (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as defined below), plus 15 basis points, plus accrued
interest on the Bonds to the date of redemption.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the
semiannual equivalent yield to maturity of the Comparable Treasury Issue (as defined below),
assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price (as defined below) for such redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker (as defined below) as having a maturity comparable to the remaining
term of the Bonds to be redeemed that would be used, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Bonds.

“Independent Investment Banker” means either Morgan Stanley & Co. Incorporated or J.P. Morgan
Securities Inc. or, if such firms are unwilling or unable to select the Comparable Treasury
Issues, an independent banking institution of national standing selected by the Company.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the
bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) on the third business day preceding such redemption date, as set forth in the
daily statistical release (or any successor release) published by the Federal Reserve Bank of New
York and designated “H.15(519)” or (2) if such release (or any successor release) is not published
or does not contain such prices on such business day, (a) the average of the Reference Treasury
Dealer Quotations (as defined below) for such redemption date, after excluding the highest and
lowest of such Reference Treasury Dealer Quotations, or (b) if the Company obtains fewer than four
such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
(as defined below) and any redemption date, the average, as determined by the Company, of the bid
and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m.
on the third business day preceding such redemption date.

“Reference Treasury Dealer” means (1) each of Morgan Stanley & Co. Incorporated, J.P. Morgan
Securities Inc. and Citigroup Global Markets Inc. and their respective successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer
in New York City (a “Primary Treasury Dealer”), the Company shall replace that former dealer with
another Primary Treasury Dealer and (2) up to four other Primary Treasury Dealers selected by the
Company.

“Remaining Scheduled Payments” means, with respect to each Bond to be redeemed, the remaining
scheduled payments of the principal thereof and interest thereon that would be due after the
related redemption date but for such redemption; provided, however, that, if that redemption date
is prior to an interest payment date with respect to such Bond, the amount of the next succeeding
scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to
that redemption date.

SECTION 4. The 2015 Bonds are not redeemable by the operation of the maintenance and
replacement provisions of the Indenture or with the proceeds of released property or in any other
manner except as set forth in Section 3 hereof.

SECTION 5. The Company reserves the right, without any consent, vote or other action by the
holders of the 2015 Bonds or of any subsequent series of bonds issued under the Indenture, to make
such amendments to the Indenture, as supplemented, as shall be necessary in order to amend Section
17.02 to read as follows:

SECTION 17.02. With the consent of the holders of not less than a majority
in principal amount of the bonds at the time outstanding or their
attorneys-in-fact duly authorized, or, if fewer than all series are
affected, not less than a majority in principal amount of the bonds at the
time outstanding of each series the rights of the holders of which are
affected, voting together, the Company, when authorized by a resolution, and
the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or modifying the rights and
obligations of the Company and the rights of the holders of any of the bonds
and coupons; provided, however, that no such supplemental indenture shall
(1) extend the maturity of any of the bonds or reduce the rate or extend the
time of payment of interest thereon, or reduce the amount of the principal
thereof, or reduce any premium payable on the redemption thereof, without
the consent of the holder of each bond so affected, or (2) permit the
creation of any lien, not otherwise permitted, prior to or on a parity with
the lien of this Indenture, without the consent of the holders of all the
bonds then outstanding, or (3) reduce the aforesaid percentage of the
principal amount of bonds the holders of which are required to approve any
such supplemental indenture, without the consent of the holders of all the
bonds then outstanding. For the purposes of this Section, bonds shall be
deemed to be affected by a supplemental indenture if such supplemental
indenture adversely affects or diminishes the rights of holders thereof
against the Company or against its property. The Trustee may in its
discretion determine whether or not, in accordance with the foregoing, bonds
of any particular series would be affected by any supplemental indenture and
any such determination shall be conclusive upon the holders of bonds of such
series and all other series. Subject to the provisions of Sections 16.02
and 16.03 hereof, the Trustee shall not be liable for any determination made
in good faith in connection herewith.

Upon the written request of the Company, accompanied by a resolution
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of bondholders as
aforesaid (the instrument or instruments evidencing such consent to be dated
within one year of such request), the Trustee shall join with the Company in
the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion but
shall not be obligated to enter into such supplemental indenture.

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

The Company and the Trustee, if they so elect, and either before or
after such consent has been obtained, may require the holder of any bond
consenting to the execution of any such supplemental indenture to submit his
bond to the Trustee or to ask such bank, banker or trust company as may be
designated by the Trustee for the purpose, for the notation thereon of the
fact that the holder of such bond has consented to the execution of such
supplemental indenture, and in such case such notation, in form satisfactory
to the Trustee, shall be made upon all bonds so submitted, and such bonds
bearing such notation shall forthwith be returned to the persons entitled
thereto.

Prior to the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the
Company shall publish a notice, setting forth in general terms the substance
of such supplemental indenture, at least once in one daily newspaper of
general circulation in each city in which the principal of any of the bonds
shall be payable, or, if all bonds outstanding shall be registered bonds
without coupons or coupon bonds registered as to principal, such notice
shall be sufficiently given if mailed, first class, postage prepaid, and
registered if the Company so elects, to each registered holder of bonds at
the last address of such holder appearing on the registry books, such
publication or mailing, as the case may be, to be made not less than thirty
days prior to such execution. Any failure of the Company to give such
notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture.

SECTION 6. As supplemented and amended as above set forth, the Indenture is in all respects
ratified and confirmed, and the Indenture and all indentures supplemental thereto shall be read,
taken and construed as one and the same instrument.

SECTION 7. The Trustee assumes no responsibility for or in respect of the validity or
sufficiency of this Supplemental Indenture or of the Indenture as hereby supplemented or the due
execution hereof by the Company or for or in respect of the recitals and statements contained
herein (other than those contained in the sixth, seventh, eighth and ninth recitals hereof), all of
which recitals and statements are made solely by the Company.

SECTION 8. This Supplemental Indenture may be simultaneously executed in several counterparts
and all such counterparts executed and delivered, each as an original, shall constitute but one and
the same instrument.

SECTION 9. In the event the date of any notice required or permitted hereunder shall not be a
Business Day (as defined below), then (notwithstanding any other provision of the Indenture or of
any supplemental indenture thereto) such notice need not be made on such date, but may be made on
the next succeeding Business Day with the same force and effect as if made on the date fixed for
such notice. “Business Day” means, with respect to this Section 9, any day, other than a Saturday
or Sunday, on which banks generally are open in New York, New York for the conduct of substantially
all of their commercial lending activities and on which interbank wire transfers can be made on the
Fedwire system.

SECTION 10. This Supplemental Indenture and the 2015 Bonds shall be governed by and deemed to
be a contract under, and construed in accordance with, the laws of the State of Michigan, and for
all purposes shall be construed in accordance with the laws of such state, except as may otherwise
be required by mandatory provisions of law.
