	ABOUT
	THIS PROSPECTUS
	 
	This prospectus is part of a registration statement that we
	filed with the United States Securities and Exchange Commission,
	or the SEC, under a shelf registration process. Under this shelf
	registration process, we may sell debt securities under this
	prospectus in one or more offerings from time to time. This
	prospectus provides you with a general description of the debt
	securities we may offer. Each time we sell securities, we will
	provide a prospectus supplement containing specific information
	about the terms of that offering. The prospectus supplement may
	also add, update or change information contained in this
	prospectus, and accordingly, to the extent inconsistent,
	information in this prospectus is superseded by the information
	in the prospectus supplement. You should read both this
	prospectus and any prospectus supplement together with
	additional information described under the heading Where
	You Can Find More Information.
	 
	The prospectus supplement will describe: the terms of the debt
	securities offered, any initial public offering price, the price
	paid to us for the debt securities, the net proceeds to us, the
	manner of distribution and any underwriting compensation and the
	other specific material terms related to the offering of these
	securities. For more detail on the terms of the debt securities,
	you should read the exhibits filed with or incorporated by
	reference in our registration statement of which this prospectus
	forms a part.
	 
	In this prospectus we use the terms Walgreens, the
	Company, we, us, and
	our to refer to Walgreen Co. and our consolidated
	subsidiaries. References to securities include any
	security that we might sell under this prospectus or any
	prospectus supplement. References to $ and
	dollars are to United States dollars.
	 
	This prospectus contains summaries of certain provisions
	contained in key documents described in this prospectus. All of
	the summaries are qualified in their entirety by the actual
	documents, which you should review before making your investment
	decision. Copies of the documents referred to herein have been
	filed, or will be filed or incorporated by reference as exhibits
	to the registration statement of which this prospectus is a
	part, and you may obtain copies of those documents as described
	below under Where You Can Find More Information.
	 
	Because we are a well-known seasoned issuer, as defined in
	Rule 405 of the Securities Act of 1933, as amended, or the
	Securities Act, we may add to and offer additional securities by
	filing a prospectus supplement with the SEC at the time of the
	offer.
	 
	You should rely only on the information contained or
	incorporated by reference in this prospectus, in any
	accompanying prospectus supplement or in any free writing
	prospectus filed by us with the SEC. We have not authorized
	anyone to provide you with different information. We are not
	making an offer of these securities in any jurisdiction where
	the offer is not permitted. You should not assume that the
	information contained in or incorporated by reference in this
	prospectus, any prospectus supplement or any free writing
	prospectus is accurate as of any date other than their
	respective dates.

	USE OF
	PROCEEDS
	 
	Unless otherwise specified in the applicable prospectus
	supplement, the net proceeds from the sale of the securities to
	which this prospectus relates will be used for general corporate
	purposes. Until we apply the proceeds from the sale of the
	securities, we may temporarily invest any proceeds that are not
	immediately applied to the above purposes in United States
	government or agency obligations, commercial paper, money market
	accounts, short-term marketable securities, bank deposits or
	certificates of deposit, repurchase agreements collateralized by
	United States government or agency obligations or other
	short-term investments.
	 
	DESCRIPTION
	OF DEBT SECURITIES
	 
	The following summarizes the material provisions of the debt
	securities to which a prospectus supplement may relate. We may
	issue debt securities from time to time in one or more series.
	Each time we offer debt securities, the prospectus supplement
	related to that offering will describe the applicable terms.
	 
	As required by United States federal law for all bonds and notes
	of companies that are publicly offered, the debt securities will
	be governed by a document called an indenture. An
	indenture is a contract to be entered into by us and a financial
	institution, acting as trustee on your behalf. The indenture is
	subject to and governed by the Trust Indenture Act of 1939,
	as amended. The trustee has two main roles:
	 
|  |  |  | 
|  |  | First, subject to some limitations, the trustee can enforce your
	rights against us if we default. | 
|  | 
|  |  | Second, the trustee performs certain administrative duties for
	us, which include sending you notices and, if the trustee also
	performs the service of paying agent, interest payments. | 
	3
 
	Because this section is a summary of the material terms, it does
	not describe every aspect of the debt securities. We urge you to
	read the indenture governing the debt securities because it, and
	not this description, defines your rights as a holder of debt
	securities. The indenture is filed as an exhibit to the
	registration statement of which this prospectus forms a part.
	This description is not complete and is subject to, and
	qualified in its entirety by reference to, all of the provisions
	of the indenture covering the debt securities, as described
	below, including definitions of some terms used in the
	indenture. The indenture is subject to any amendments or
	supplements that we may enter into from time to time, as
	permitted under the indenture.
	 
	References to Walgreens, we,
	us and our in this section are only to
	Walgreen Co. and not to its subsidiaries.
	 
	General
	 
	Unless otherwise provided in the applicable prospectus
	supplement, the debt securities will be unsecured senior
	obligations of our company. As senior debt securities, they will
	rank equally with all of our other unsecured and unsubordinated
	indebtedness.
	 
	Our debt securities are effectively subordinated to all
	existing and future indebtedness and other liabilities,
	including trade payables and capital lease obligations, of any
	of our subsidiaries. This may affect your ability to receive
	payments on our debt securities.
	 
	The indenture provides for the issuance by us from time to time
	of debt securities in one or more series. The indenture does not
	limit the aggregate principal amount of debt securities we may
	issue under the indenture. In addition, the indenture does not
	limit the amount of other indebtedness or debt securities, other
	than certain secured indebtedness to the extent described in the
	prospectus supplement relating to that series of debt securities
	that may be issued by Walgreens or its subsidiaries.
	 
	The indenture sets forth the specific terms of any series of
	debt securities or provides that such terms will be set forth
	in, or determined pursuant to, an authorizing resolution and
	officers certificate or a supplemental indenture, if any,
	relating to that series.
	 
	You should read the prospectus supplement relating to a
	particular series of debt securities for the following terms of
	the series of debt securities offered by that prospectus
	supplement and this prospectus:
	 
|  |  |  | 
|  |  | the title of the debt securities and the series in which the
	debt securities will be included, which may include medium-term
	notes; | 
|  | 
|  |  | any limit upon the aggregate principal amount of the debt
	securities; | 
|  | 
|  |  | the date or dates, or the method or methods, if any, by which
	the date or dates on which the principal of the debt securities
	will be payable shall be determined; | 
|  | 
|  |  | the rate or rates at which the debt securities will bear
	interest, if any, which rate may be zero in the case of some
	debt securities issued at an issue price representing a discount
	from the principal amount payable at maturity, or the method by
	which the rate or rates will be determined (including, if
	applicable, any remarketing option or similar method), and the
	date or dates from which the interest, if any, will accrue or
	the method by which the date or dates will be determined; | 
|  | 
|  |  | the date or dates on which the interest, if any, on the debt
	securities will be payable and any regular record dates
	applicable to the date or dates on which interest will be so
	payable; | 
|  | 
|  |  | whether and under what circumstances additional amounts, if any,
	on the debt securities or any of them will be payable and, if
	so, whether and on what terms we will have the option to | 
	4
 
|  |  |  | 
|  |  | redeem the debt securities in lieu of paying the additional
	amounts (and the terms of the option); | 
	 
|  |  |  | 
|  |  | the place or places where the principal of, any premium or
	interest on or any additional amounts with respect to the debt
	securities will be payable, any of the debt securities that are
	registered securities may be surrendered for registration of
	transfer or exchange, and any debt securities may be surrendered
	for conversion or exchange; | 
|  | 
|  |  | whether any of the debt securities may be redeemed at our option
	and, if so, the date or dates on which, the period or periods
	within which, the price or prices at which, and the other terms
	and conditions upon which the debt securities may be redeemed,
	in whole or in part; | 
|  | 
|  |  | whether we will be obligated to redeem or purchase any of the
	debt securities pursuant to any sinking fund or analogous
	provision or at the option of any holder of the debt securities
	and, if so, the date or dates on which, the period or periods
	within which, the price or prices at which, and the other terms
	and conditions upon which the debt securities will be redeemed
	or purchased, in whole or in part, and any provisions for the
	remarketing of the debt securities so redeemed or purchased; | 
|  | 
|  |  | if other than denominations of $2,000 and integral multiples of
	$1,000 in excess thereof, the denominations in which any
	registered securities will be issuable and, if other than a
	denomination of $5,000, the denominations in which any bearer
	securities will be issuable; | 
|  | 
|  |  | if other than the principal amount, the portion of the principal
	amount (or the method by which such portion will be determined)
	of the debt securities that will be payable upon declaration of
	acceleration of maturity; | 
|  | 
|  |  | if other than United States dollars, the currency of payment,
	including composite currencies, of the principal of, any premium
	or interest on or any additional amounts with respect to any of
	the debt securities; | 
|  | 
|  |  | whether the principal of, any premium or interest on or any
	additional amounts with respect to the debt securities will be
	payable, at the election of Walgreens or a holder, in a currency
	other than that in which the debt securities are stated to be
	payable and the date or dates on which, the period or periods
	within which, and the other terms and conditions upon which, the
	election may be made; | 
|  | 
|  |  | any index, formula or other method used to determine the amount
	of payments of principal of, any premium or interest on or any
	additional amounts with respect to debt securities; | 
|  | 
|  |  | whether the debt securities are to be issued in the form of one
	or more global securities and, if so, the identity of the
	depositary for the global security or securities; | 
|  | 
|  |  | any deletions from, modifications of or additions to the events
	of default or covenants of Walgreens with respect to the debt
	securities; | 
|  | 
|  |  | whether some of the provisions relating to the discharge,
	defeasance and covenant defeasance described below under
	 Discharge, Defeasance and Covenant
	Defeasance will be applicable to the debt securities; and | 
|  | 
|  |  | any other terms of the debt securities and any other deletions
	from or modifications or additions to the indenture in respect
	of the debt securities. | 
	 
	Unless otherwise provided in the prospectus supplement relating
	to any series of debt securities, the principal, premium,
	interest and additional amounts, if any, will be payable at the
	office or agency maintained by
	5
 
	us (initially a corporate trust office designated by the
	Trustee); provided that payment of interest on registered
	securities may be made by check mailed to the payee at the
	addresses of the persons appearing on the security register or
	by transfer to an account maintained by the payee with a bank
	located in the United States. In the case of registered
	securities, interest on the debt securities will be payable on
	any interest payment date to the persons in whose names the debt
	securities are registered at the close of business on the record
	date. All paying agents initially designated by us for the debt
	securities of a particular series will be named in the
	prospectus supplement relating to those debt securities. We may
	at any time designate additional paying agents or rescind the
	designation of any paying agent or approve a change in the
	office through which any paying agent acts, except that we will
	be required to maintain a paying agent in each place of payment
	for the affected debt securities.
	 
	Unless otherwise provided in the prospectus supplement relating
	to any series of debt securities, the debt securities may be
	presented for transfer (duly endorsed or accompanied by a
	written instrument of transfer, if so required by us or the
	security registrar) or exchanged for other debt securities of
	the same series (containing identical terms and provisions, in
	any authorized denominations, and of a like aggregate principal
	amount) at the office or agency maintained by us (initially a
	corporate trust office designated by the Trustee). The transfer
	or exchange will be made without service charge, but we may
	require payment of a sum sufficient to cover any tax or other
	governmental charge and any other expenses payable in connection
	with any registration of transfer or exchange of debt
	securities. We will not be required to (1) issue, register
	the transfer of, or exchange, debt securities during a period
	beginning at the opening of business 15 days before the
	mailing of a notice of redemption of any of the debt securities
	of that series and ending at the close of business on the day of
	the mailing of the notice of redemption or (2) register the
	transfer of or exchange any debt security so selected for
	redemption in whole or in part, except the unredeemed portion of
	any debt security being redeemed in part.
	 
	We have appointed the Trustee as security registrar. Any
	transfer agent (in addition to the security registrar) initially
	designated by us for any series of debt securities will be named
	in the applicable prospectus supplement. We may at any time
	designate additional transfer agents or rescind the designation
	of any transfer agent or approve a change in the office through
	which any transfer agent acts, except that we will be required
	to maintain a transfer agent in each place of payment for the
	affected debt securities.
	 
	Unless otherwise indicated in the applicable prospectus
	supplement, the debt securities will be issued only in fully
	registered form without coupons in minimum denominations of
	$2,000 and integral multiples of $1,000 in excess thereof. The
	debt securities may be represented in whole or in part by one or
	more global debt securities registered in the name of a
	depositary or its nominee and, if so represented, interests in
	the global debt security will be shown on, and transfers will be
	effected only through, records maintained by the designated
	depositary and its participants as described below. Where debt
	securities of any series are issued in bearer form, the special
	restrictions and considerations, including special offering
	restrictions and United States federal income tax
	considerations, applicable to the those debt securities and to
	payment on and transfer and exchange of those debt securities
	will be described in the applicable prospectus supplement.
	 
	We may issue debt securities with terms different from those of
	debt securities that may already have been issued. Without the
	consent of the holders thereof, we may reopen a previous issue
	of a series of debt securities and issue additional debt
	securities of that series without limit unless the reopening was
	restricted when that series was created.
	 
	There is no requirement that we issue debt securities in the
	future under the same indenture, and we may use other indentures
	or documentation, containing materially different provisions in
	connection with future issues of other debt securities.
	 
	We may issue the debt securities as original issue discount
	securities, which are debt securities, including any zero-coupon
	debt securities, that are issued and sold at a discount from
	their stated principal amount. Original issue discount
	securities provide that, upon acceleration of their maturity, an
	amount less than their principal amount will become due and
	payable. We will describe the United States federal income tax
	consequences and other considerations applicable to original
	issue discount securities in any prospectus supplement relating
	to them.
	6
 
	In addition, special United States federal income tax
	considerations or other restrictions or other terms applicable
	to any debt securities offered exclusively to foreigners or
	denominated in a currency other than United States dollars may
	also be set forth in the prospectus supplement, if applicable.
	 
	We will comply with Section 14(c) of the Securities
	Exchange Act of 1934, as amended (the Exchange Act),
	and any other tender offer rules within the Exchange Act, which
	may then be applicable, if we are obligated to purchase debt
	securities at the option of the holders of the securities. Any
	obligation applicable to a series of debt securities will be
	described in the applicable prospectus supplement.
	 
	Unless otherwise described in a prospectus supplement relating
	to any series of debt securities, the indenture does not contain
	any provisions that would limit our ability to incur
	indebtedness or that would afford holders of debt securities
	protection in the event of a sudden and significant decline in
	our credit quality or a takeover, recapitalization or highly
	leveraged or similar transaction involving our company.
	Accordingly, we could in the future enter into transactions that
	could increase the amount of indebtedness outstanding at that
	time or otherwise affect our capital structure or credit rating.
	Reference is made to the prospectus supplement relating to the
	particular series of debt securities being offered for
	information about any deletions from, modifications or additions
	to the events of default described below or covenants of
	Walgreens in the indenture, including any addition of a covenant
	or other provisions providing event risk or similar protection.
	 
	Conversion
	and Exchange
	 
	If any debt securities are convertible, they may be convertible
	into or exchangeable for securities, property or cash, or a
	combination of the foregoing, and the prospectus supplement will
	explain the terms and conditions of such conversion or exchange,
	including:
	 
|  |  |  | 
|  |  | the securities, property or cash into which the debt securities
	are convertible or for which they are exchangeable; | 
|  | 
|  |  | the conversion price or exchange ratio, or the calculation
	method for such price or ratio; | 
|  | 
|  |  | the conversion or exchange period, or how such period will be
	determined; | 
|  | 
|  |  | if conversion or exchange will be mandatory or at the option of
	the holder or our company; | 
|  | 
|  |  | provisions for adjustment of the conversion price or the
	exchange ratio; | 
|  | 
|  |  | provisions affecting conversion or exchange in the event of the
	redemption of the debt securities; and | 
|  | 
|  |  | any other terms of the debt securities that are consistent with
	the provisions of the indenture. | 
	 
	Such terms may also include provisions under which the number or
	amount of other securities or property to be received by the
	holders of such debt securities upon conversion or exchange
	would be calculated according to the market price of such other
	securities or property as of a time stated in the prospectus
	supplement.
	 
	Global
	Securities
	 
	The debt securities of a series may be issued in whole or in
	part in the form of one or more global debt securities (each a
	Global Security) that will be deposited with, or on
	behalf of, a depositary identified in the prospectus supplement
	relating to that particular series.
	7
 
	The specific terms of a depositary arrangement with respect to a
	series of debt securities will be described in the prospectus
	supplement relating to that particular series. We anticipate
	that the following provisions will apply to all depositary
	arrangements.
	 
	Upon the issuance of a Global Security, the depositary for the
	Global Security or its nominee will credit, on its book-entry
	registration and transfer system, the respective principal
	amounts of the debt securities represented by the Global
	Security. These accounts will be designated by the underwriters
	or agents with respect to such debt securities or by us if the
	debt securities are offered and sold directly by us. Ownership
	of beneficial interests in a Global Security will be limited to
	persons that may hold interests through participants. Ownership
	of beneficial interests in such a Global Security will be shown
	on, and the transfer of that ownership will be effected only
	through, records maintained by the depositary or its nominee
	(with respect to interests of participants) for such Global
	Security and on the records of participants (with respect to
	interests of persons other than participants). The laws of some
	states require that some purchasers of securities take physical
	delivery of such securities in definitive form. These limits and
	laws may impair the ability to transfer beneficial interests in
	a Global Security.
	 
	So long as the depositary for a Global Security, or its nominee,
	is the registered owner of the Global Security, such depositary
	or such nominee, as the case may be, will be considered the sole
	owner or holder of the debt securities represented by the Global
	Security for all purposes under the indenture governing these
	debt securities. Except as provided below, owners of beneficial
	interests in a Global Security will not be entitled to have debt
	securities of the series represented by the Global Security
	registered in their names, will not receive or be entitled to
	receive physical delivery of debt securities of a series in
	definitive form and will not be considered the owners or holders
	of the debt securities under the indenture.
	 
	Principal of, any premium and interest on, and any additional
	amounts with respect to debt securities registered in the name
	of a depositary or its nominee will be made to the depositary or
	its nominee, as the case may be, as the registered owner of the
	Global Security representing the debt securities. None of
	Walgreens, the Trustee, the paying agent or the security
	registrar will have any responsibility or liability for any
	aspect of the records relating to or payments made on account of
	beneficial ownership interests of the Global Security for the
	debt securities or for maintaining, supervising or reviewing any
	records relating to the beneficial ownership interests.
	 
	We expect that the depositary for a series of debt securities or
	its nominee, upon receipt of any payment of principal of,
	premium, if any, or interest on, or additional amounts with
	respect to debt securities, will immediately credit
	participants accounts with payments in amounts
	proportionate to their respective beneficial interest in the
	principal amount of the Global Security for the debt securities
	as shown on the records of the depositary or its nominee. We
	also expect that payments by participants to owners of
	beneficial interests in the Global Security held through the
	participants will be governed by standing instructions and
	customary practices, as is now the case with securities held for
	the accounts of customers registered in street name,
	and will be the sole responsibility of the participants.
	 
	The indenture provides that if (1) the depositary for a
	series of debt securities notifies us that it is unwilling or
	unable to continue as depositary or if the depositary ceases to
	be eligible under the indenture and a successor depositary is
	not appointed by us within 90 days of written notice,
	(2) we determine that the debt securities of a particular
	series will no longer be represented by Global Securities and
	execute and deliver to the Trustee a company order to that
	effect or (3) an event of default with respect to a series
	of debt securities has occurred and is continuing and the
	depositary requests the issuance of certificated notes, the
	Global Securities will be exchanged for debt securities of a
	series in definitive form of like tenor and of an equal
	aggregate principal amount, in authorized denominations. The
	definitive debt securities will be registered in such name or
	names as the depositary instructs the Trustee. We expect that
	these instructions may be based upon directions received by the
	depositary from participants with respect to ownership of
	beneficial interests in Global Securities.
	8
 
	Events of
	Default
	 
	Each of the following events will constitute an event of default
	under the indenture with respect to any series of debt
	securities issued:
	 
|  |  |  | 
|  |  | default in the payment of any interest on any debt security of
	the series, or any additional amounts payable, when interest or
	additional amounts become due and payable, and continuance of
	such default for a period of 30 days; | 
|  | 
|  |  | default in the payment of the principal of or any premium on any
	debt security of the series, or any additional amounts payable,
	when principal, premium or additional amounts become due and
	payable at maturity, upon any redemption, upon declaration of
	acceleration or otherwise; | 
|  | 
|  |  | default in the deposit of any sinking fund payment, when and as
	due by the terms of any debt security of the series; | 
|  | 
|  |  | default in the performance, or breach, of any covenant or
	warranty of Walgreens contained in the indenture for the benefit
	of the series or in the debt securities of the series (other
	than a covenant or warranty a default in the performance or the
	breach of which is dealt with elsewhere in the indenture or
	which is expressly included in the indenture solely for the
	benefit of a series of debt securities other than such series),
	and the continuance of such default or breach for a period of
	60 days after written notice as provided in the indenture; | 
|  | 
|  |  | if any event of default as defined in any mortgage, indenture or
	instrument under which any of our debt is issued, secured or
	evidenced (including any event of default under any other series
	of debt securities), whether the debt now exists or is created
	or incurred in the future, happens and consists of the default
	in the payment of more than $100 million in principal
	amount of the debt at its maturity (after giving effect to any
	applicable grace period) or results in more than
	$100 million of the debt becoming or being declared due and
	payable before it is otherwise due and payable; provided,
	however, that, if the default under the mortgage, indenture or
	instrument is cured by us, or waived by the holders of the debt,
	in each case as may be permitted by the mortgage, indenture or
	instrument, then the event of default under the indenture
	governing the debt securities caused by such default will be
	deemed likewise to be cured or waived; | 
|  | 
|  |  | particular events in bankruptcy, insolvency or reorganization of
	Walgreens; and | 
|  | 
|  |  | any other event of default under the indenture with respect to
	debt securities of the series. | 
	 
	No event of default with respect to a particular series of debt
	securities issued under the indenture necessarily constitutes an
	event of default with respect to any other series of debt
	securities issued thereunder. Any modifications to the foregoing
	events of default will be described in any prospectus supplement.
	 
	The indenture provides that if an event of default with respect
	to the debt securities of any series (other than an event of
	default described in the sixth bullet above) occurs and is
	continuing, either the Trustee or the holders of at least 25% in
	principal amount of the outstanding debt securities of the
	series by written notice as provided in the indenture may
	declare the principal amount (or a lesser amount as may be
	provided for in the debt securities of the series) of all
	outstanding debt securities of the series to be due and payable
	immediately. At any time after a declaration of acceleration is
	made, but before a judgment or decree for payment of money is
	obtained by the Trustee, and subject to applicable law and
	particular other provisions of the indenture, the holders of a
	majority in aggregate principal amount of the debt securities
	may, under some circumstances, rescind and annul acceleration.
	 
	An event of default described in the sixth bullet of the
	immediately preceding paragraph will cause the principal amount
	and accrued interest (or a lesser amount as provided for in the
	debt securities of the series) to become immediately due and
	payable without any declaration or other act by the Trustee or
	any holder.
	9
 
	The indenture provides that, within 90 days after the
	occurrence of a default with respect to the debt securities of
	any series, the Trustee will deliver, in the manner set forth in
	the indenture, a notice of default to the holders of the debt
	securities of the series unless the default has been cured or
	waived. Except in the case of a default in the payment of
	principal of, or premium, if any, or interest, if any, on, or
	additional amounts or any sinking fund or purchase fund
	installment with respect to, any debt security of the series,
	the Trustee may withhold notice if it in good faith determines
	that the withholding of the notice is in the best interest of
	the holders of debt securities of the series. Further, in the
	case of any default specified in the fourth bullet of the first
	paragraph above, no notice of default will be given to holders
	of the debt securities of the affected series until at least
	60 days after the occurrence thereof.
	 
	If an event of default occurs and is continuing with respect to
	the debt securities of any series, the Trustee may in its
	discretion proceed to protect and enforce its rights and the
	rights of the holders of debt securities of the series by all
	appropriate judicial proceedings.
	 
	The indenture provides that, subject to the duty of the Trustee
	to act with the required standard of care, the Trustee will be
	under no obligation to exercise any of its rights or powers
	under the indenture at the request or direction of the holders
	of the debt securities, unless the holders offer to the Trustee
	reasonable indemnity.
	 
	Subject to the provisions for the indemnification of the
	Trustee, and subject to applicable law and particular other
	provisions of the indenture, the holders of a majority in
	aggregate principal amount of the outstanding debt securities of
	any series will have the right to direct the time, method and
	place of conducting any proceeding for any remedy available to
	the Trustee, or exercising any trust or power conferred on the
	Trustee, with respect to the debt securities of the series.
	 
	Under the indenture, we are required annually to furnish to the
	Trustee a statement as to performance by us of some of our
	obligations under the indenture and as to any default in such
	performance. We are also required to deliver to the Trustee a
	written notice within five business days after becoming aware of
	any event of default or any event which after notice or lapse of
	time or both would constitute an event of default under the
	fourth bullet point above.
	 
	Modification
	and Waiver
	 
	The indenture may be modified or amended by us and the Trustee
	with the consent of the holders of a majority in aggregate
	principal amount of the outstanding debt securities of each
	series affected by the modification or amendment; provided,
	however, that no modification or amendment may, without the
	consent of the holder of each outstanding debt security affected
	by the modification or amendment:
	 
|  |  |  | 
|  |  | change the stated maturity of the principal of, or any premium
	or installment of interest on, or any additional amounts with
	respect to, any debt security; | 
|  | 
|  |  | reduce the principal amount of, or the rate (or modify the
	calculation of the rate in a manner that may reduce the rate) of
	interest on, or any additional amounts with respect to, or any
	premium payable upon the redemption of any debt security or
	otherwise; | 
|  | 
|  |  | change our obligation to pay additional amounts with respect to
	any debt security or reduce the amount of the principal of an
	original issue discount security that would be due and payable
	upon a declaration of acceleration of the maturity or the amount
	provable in bankruptcy; | 
|  | 
|  |  | change the redemption provisions of any debt security or
	adversely affect the right of repayment at the option of any
	holder of any debt security; | 
|  | 
|  |  | change the place of payment or the currency in which the
	principal of, any premium or interest on or any additional
	amounts with respect to any debt security is payable; | 
	10
 
|  |  |  | 
|  |  | impair the right to institute suit for the enforcement of any
	payment on or after the stated maturity of any debt security
	(or, in the case of redemption, on or after the redemption date
	or, in the case of repayment at the option of any holder, on or
	after the date for repayment); | 
|  | 
|  |  | reduce the percentage in principal amount of the outstanding
	debt securities, the consent of whose holders is required in
	order to take certain actions; | 
|  | 
|  |  | reduce the requirements for quorum or voting by holders of debt
	securities in the indenture; | 
|  | 
|  |  | modify any of the provisions in the indenture regarding the
	waiver of past defaults and the waiver of some covenants by the
	holders of debt securities except to increase any percentage
	vote required or to provide that some other provisions of the
	indenture cannot be modified or waived without the consent of
	the holder of each debt security affected; | 
|  | 
|  |  | make any change that adversely affects the right to convert or
	exchange any debt security into or for shares of common stock of
	Walgreens or other debt securities in accordance with its terms;
	or | 
|  | 
|  |  | modify any of the provisions described in the immediately
	preceding bullets. | 
	 
	The holders of a majority in aggregate principal amount of the
	debt securities of any series may, on behalf of the holders of
	all debt securities of the series, waive our compliance with a
	number of restrictive provisions of the indenture. The holders
	of a majority in aggregate principal amount of the outstanding
	debt securities of any series may, on behalf of the holders of
	all debt securities of the series, waive any past default and
	its consequences under the indenture with respect to the debt
	securities of the series, except a default (a) in the
	payment of principal of (or premium, if any), any interest on or
	any additional amounts with respect to debt securities of the
	series or (b) in respect of a covenant or provision of the
	indenture that cannot be modified or amended without the consent
	of the holder of each debt security of any series.
	 
	Discharge,
	Defeasance and Covenant Defeasance
	 
	We may discharge some obligations to holders of any series of
	debt securities not yet delivered to the Trustee for
	cancellation and that either became due and payable or will
	become due and payable within one year (or scheduled for
	redemption within one year) by depositing with the Trustee, in
	trust, funds in United States dollars or in the foreign currency
	in which the debt securities are payable in an amount sufficient
	to pay the entire indebtedness on the debt securities with
	respect to principal (and premium, if any), any additional
	amounts and interest to the date of deposit (if the debt
	securities have become due and payable) or to the maturity or
	redemption of the debt securities, as the case may be.
	 
	The indenture provides that, unless the provisions of the
	indenture relating to defeasance and discharge are made
	inapplicable to the debt securities of or within any series
	pursuant to the indenture, we may elect either:
	 
|  |  |  | 
|  |  | to defease and be discharged from any and all obligations with
	respect to the debt securities (except for, among other things,
	the obligation to pay additional amounts, if any, upon the
	occurrence of particular events of taxation, assessment or
	governmental charge with respect to payments on the debt
	securities and other obligations to register the transfer or
	exchange of the debt securities, to replace temporary or
	mutilated, destroyed, lost or stolen debt securities, to
	maintain an office or agency with respect to the debt securities
	and to hold moneys for payment in trust)
	(
	defeasance
	) or | 
|  | 
|  |  | to be released from our obligations with respect to the debt
	securities under certain covenants as described in the
	applicable prospectus supplement, and any omission to comply
	with these obligations will not constitute a default or an event
	of default with respect to the debt securities
	(
	covenant defeasance
	). | 
	11
 
	Defeasance or covenant defeasance, as the case may be, will be
	conditioned upon the irrevocable deposit by us with the Trustee,
	in trust, of an amount in United States dollars or in the
	foreign currency in which the debt securities are payable, or
	Government Obligations (as defined below), or both, which
	through the scheduled payment of principal and interest in
	accordance with their terms will provide money in an amount
	sufficient to pay the principal of (and premium, if any) and
	interest on the debt securities on the scheduled due dates
	(including any redemption date that we irrevocably specify at
	the time of defeasance or covenant defeasance) and any mandatory
	sinking fund payments or analogous payments, if applicable.
	 
	Such a trust may be established only if, among other things,
	(1) the applicable defeasance or covenant defeasance does
	not result in a breach or violation of, or constitute a default
	under, the indenture or any other material agreement or
	instrument to which we are a party or by which we are bound,
	(2) no event of default or event that with notice or lapse
	of time or both would become an event of default with respect to
	the debt securities to be defeased occurred and is continuing on
	the date of establishment of the trust and, with respect to
	defeasance only, at any time during the period ending on the
	91st day after such date and (3) we have delivered to
	the Trustee an opinion of counsel (as specified in the
	indenture) to the effect that the holders of the debt securities
	will not recognize income, gain or loss for United States
	federal income tax purposes as a result of such defeasance or
	covenant defeasance and will be subject to United States federal
	income tax on the same amounts, in the same manner and at the
	same times as would have been the case if such defeasance or
	covenant defeasance had not occurred, and such opinion of
	counsel, in the case of defeasance, must refer to and be based
	upon a letter ruling of the Internal Revenue Service received by
	us, a Revenue Ruling published by the Internal Revenue Service
	or a change in applicable United States federal income tax law
	occurring after the date of the indenture.
	 
	
	Foreign Currency
	 means any currency, currency
	unit or composite currency, including, without limitation, the
	Euro, issued by the government of one or more countries other
	than the United States of America or by any recognized
	confederation or association of such governments.
	 
	
	Government Obligations
	 means securities that
	are (1) direct obligations of the United States of America
	or the government or governments that issued the Foreign
	Currency in which the debt securities of a particular series are
	payable, for the payment of which its full faith and credit is
	pledged, or (2) obligations of a person controlled or
	supervised by and acting as an agency or instrumentality of the
	United States of America or the government or governments that
	issued the Foreign Currency in which the debt securities of such
	series are payable, the timely payment of which is
	unconditionally guaranteed as a full faith and credit obligation
	by the United States of America or other government or
	governments, which, in the case of clauses (1) and (2), are
	not callable or redeemable at the option of the issuer or
	issuers, and also include a depositary receipt issued by a bank
	or trust company as custodian with respect to any Government
	Obligation or a specific payment of interest on or principal of
	or any other amount with respect to any Government Obligation
	held by the custodian for the account of the holder of the
	depositary receipt, provided that (except as required by law)
	the custodian is not authorized to make any deduction from the
	amount payable to the holder of the depositary receipt from any
	amount received by the custodian with respect to the Government
	Obligation or the specific payment of interest on or principal
	of or any other amount with respect to the Government Obligation
	evidenced by the depositary receipt.
	 
	If after we have deposited funds or Government Obligations to
	effect defeasance or covenant defeasance with respect to debt
	securities of any series, (a) the holder of a debt security
	of the series is entitled to, and does, elect pursuant to the
	indenture or the terms of the debt security to receive payment
	in a currency other than that in which the deposit has been made
	in respect of the debt security, or (b) a Conversion Event
	(as defined below) occurs in respect of the Foreign Currency in
	which the deposit has been made, the indebtedness represented by
	the debt security will be deemed to have been, and will be,
	fully discharged and satisfied through the payment of the
	principal of (and premium, if any) and interest, if any, on, and
	additional amounts, if any, with respect to such debt security
	as the debt security becomes due out of the proceeds yielded by
	converting the amount or other properties so deposited in
	respect of the debt security into the currency in which the debt
	security becomes payable as a result of such election or
	Conversion Event based on (x) in the case of payments made
	pursuant to clause (a) above, the applicable market
	exchange rate for the currency in effect on the second business
	day prior
	12
 
	to the payment date, or (y) with respect to a Conversion
	Event, the applicable market exchange rate for the Foreign
	Currency in effect (as nearly as feasible) at the time of the
	Conversion Event.
	 
	
	Conversion Event
	 means the cessation of use
	of (1) a Foreign Currency both by the government of the
	country or the confederation that issued the Foreign Currency
	and for the settlement of transactions by a central bank or
	other public institutions of or within the international banking
	community or (2) any currency unit or composite currency
	for the purposes for which it was established.
	 
	In the event that we effect covenant defeasance with respect to
	any debt securities and the debt securities are declared due and
	payable because of the occurrence of any event of default (other
	than an event of default with respect to any covenant as to
	which there has been covenant defeasance), if the amount in
	United States dollars or the Foreign Currency in which the debt
	securities are payable, and Government Obligations on deposit
	with the Trustee, will be sufficient to pay amounts due on the
	debt securities at the time of the stated maturity or earlier
	redemption but is not sufficient to pay amounts due on the debt
	securities at the time of the acceleration resulting from the
	event of default, Walgreens will remain liable to make payment
	of the amounts due at the time of acceleration.

	Law
	 
	The indenture and the debt securities will be governed by, and

	into and, in each case, performed in said state.

	PLAN OF
	DISTRIBUTION
	 
	We may sell our securities in any one or more of the following
	ways from time to time: (i) through agents; (ii) to or
	through underwriters; (iii) through brokers or dealers;
	(iv) directly by us to purchasers, including through a
	specific bidding, auction or other process; or (v) through
	a combination of any of these methods of sale. The applicable
	prospectus supplement will contain the terms of the transaction,
	name or names of any underwriters, dealers, agents and the
	respective amounts of securities underwritten or purchased by
	them, the initial public offering price of the securities, and
	the applicable agents commission, dealers purchase
	price or underwriters discount. Any dealers and agents
	participating in the distribution of the securities may be
	deemed to be underwriters, and compensation received by them on
	resale of the securities may be deemed to be underwriting
	discounts.
	 
	Any initial offering price, dealer purchase price, discount or
	commission may be changed from time to time.
	 
	The securities may be distributed from time to time in one or
	more transactions, at negotiated prices, at a fixed or fixed
	prices (that may be subject to change), at market prices
	prevailing at the time of sale, at various prices determined at
	the time of sale or at prices related to prevailing market
	prices.
	 
	Offers to purchase securities may be solicited directly by us or
	by agents designated by us from time to time. Any such agent may
	be deemed to be an underwriter, as that term is defined in the
	Securities Act, of the securities so offered and sold.
	 
	If underwriters are utilized in the sale of any securities in
	respect of which this prospectus is being delivered, such
	securities will be acquired by the underwriters for their own
	account and may be resold from time to time in one or more
	transactions, including negotiated transactions, at fixed public
	offering prices or at varying prices determined by the
	underwriters at the time of sale. Securities may be offered to
	the public either through underwriting syndicates represented by
	managing underwriters or directly by one or more underwriters.
	If any underwriter or underwriters are utilized in the sale of
	securities, unless otherwise indicated in the applicable
	prospectus supplement, the obligations of the underwriters are
	subject to certain conditions precedent and the underwriters
	will be obligated to purchase all such securities if any are
	purchased.
	 
	If a dealer is utilized in the sale of the securities in respect
	of which this prospectus is delivered, we will sell such
	securities to the dealer, as principal. The dealer may then
	resell such securities to the public at varying prices to be
	determined by such dealer at the time of resale. Transactions
	through brokers or dealers may include block trades in which
	brokers or dealers will attempt to sell securities as agent but
	may position and resell as principal to facilitate the
	transaction or in crosses, in which the same broker or dealer
	acts as agent on both sides of the trade. Any such dealer may be
	deemed to be an underwriter, as such term is defined in the
	Securities Act, of the securities so offered and sold.
	 
	Offers to purchase securities may be solicited directly by us
	and the sale thereof may be made by us directly to institutional
	investors or others, who may be deemed to be underwriters within
	the meaning of the Securities Act with respect to any resale
	thereof.
	 
	If so indicated in the applicable prospectus supplement, we may
	authorize agents and underwriters to solicit offers by certain
	institutions to purchase securities from us or at the public
	offering price set forth in the applicable prospectus supplement
	pursuant to delayed delivery contracts providing for payment and
	delivery on the date or dates stated in the applicable
	prospectus supplement. Such delayed delivery contracts will be
	subject only to those conditions set forth in the applicable
	prospectus supplement.
	 
	Agents, underwriters and dealers may be entitled under relevant
	agreements with us to indemnification by us against certain
	liabilities, including liabilities under the Securities Act, or
	to contribution with respect to payments that such agents,
	underwriters and dealers may be required to make in respect
	thereof. The terms and conditions of any indemnification or
	contribution will be described in the applicable prospectus
	supplement.
	14
 
	 
	Underwriters, broker-dealers or agents may receive compensation
	in the form of commissions, discounts or concessions from us.
	Underwriters, broker-dealers or agents may also receive
	compensation from the purchasers of securities for whom they act
	as agents or to whom they sell as principals, or both.
	Compensation as to a particular underwriter, broker-dealer or
	agent might be in excess of customary commissions and will be in
	amounts to be negotiated in connection with transactions. In
	effecting sales, broker-dealers engaged by us may arrange for
	other broker-dealers to participate in the resales.
	 
	Each series of securities will be a new issue and will have no
	established trading market. We may elect to list any series of
	securities on an exchange, but, unless otherwise specified in
	the applicable prospectus supplement, we shall not be obligated
	to do so. No assurance can be given as to the liquidity of the
	trading market for any of the securities.
	 
	Agents, underwriters and dealers may engage in transactions
	with, or perform services for, us and our respective
	subsidiaries in the ordinary course of business.
	 
	Any underwriter may engage in overallotment, stabilizing
	transactions, short covering transactions and penalty bids in
	accordance with Regulation M under the Exchange Act.
	Overallotment involves sales in excess of the offering size,
	which create a short position. Stabilizing transactions permit
	bids to purchase the underlying security so long as the
	stabilizing bids do not exceed a specified maximum. Short
	covering transactions involve purchases of the securities in the
	open market after the distribution is completed to cover short
	positions. Penalty bids permit the underwriters to reclaim a
	selling concession from a dealer when the securities originally
	sold by the dealer are purchased in a covering transaction to
	cover short positions. Those activities may cause the price of
	the securities to be higher than it would otherwise be. If
	commenced, the underwriters may discontinue any of the
	activities at any time. An underwriter may carry out these
	transactions on a stock exchange, in the over-the-counter market
	or otherwise.
	 
	The place and time of delivery for securities will be set forth
	in the accompanying prospectus supplement for such securities.

	MATTERS

	accompanying this prospectus, Drinker Biddle & Reath

	validity of the securities and other legal matters. As of
	July 1, 2008, attorneys of Drinker Biddle & Reath

	named in the prospectus supplement.

| Item 15. | Indemnification
	of Directors and Officers | 
	 
	Limitation
	on Liability of Directors
	 
	Section 8.75 of the Illinois Business Corporation Act (the
	IBCA) provides that a corporation may indemnify any
	person who, by reason of the fact that such person is or was a
	director, officer, employee or agent of such corporation, or who
	is or was serving at the request of the corporation as a
	director, officer, employee or agent of another corporation,
	partnership, joint venture, trust or other enterprise, is made a
	party to any threatened, pending or completed action, suit or
	proceeding, whether civil, criminal, administrative or
	investigative, other than one brought on behalf of the
	corporation, against expenses (including attorneys fees),
	judgments, fines and settlement payments actually and reasonably
	incurred in connection with the action, suit or proceeding, if
	such person acted in good faith and in a manner he or she
	reasonably believed to be in, or not opposed to, the best
	interests of such corporation and, in criminal actions or
	proceedings, had no reasonable cause to believe his or her
	conduct was unlawful. In the case of actions on behalf of the
	corporation, indemnification may extend only to expenses
	(including attorneys fees) actually and reasonably
	incurred in connection with the defense or settlement of such
	action or suit and only if such person acted in good faith and
	in a manner he or she reasonably believed to be in, or not
	opposed to, the best interests of the corporation, provided that
	no such indemnification is permitted in respect of any claim,
	issue or matter as to which such person is adjudged to be liable
	to the corporation except to the extent that the adjudicating
	court otherwise provides. To the extent that a present or former
	director, officer or employee of the corporation has been
	successful in defending any such action, suit or proceeding
	(even one on behalf of the corporation) or in defense of any
	claim, issue or matter therein, such person is entitled to
	indemnification for expenses (including attorneys fees)
	actually and reasonably incurred by such person in connection
	therewith if the person acted in good faith and in a manner he
	or she reasonably believed to be in, or not opposed to, the best
	interests of the corporation. Expenses (including
	attorneys fees) incurred by an officer or director in
	defending an action, suit, or proceeding may be paid by the
	corporation in advance of the final disposition of such action,
	suit, or proceeding, provided that the director or officer
	undertakes to repay such advances should it ultimately be
	determined that the officer or director is not entitled to be
	indemnified pursuant to Section 8.75 of the IBCA.
	 
	The By-Laws of the registrant provide that the registrant shall,
	in the case of persons who are or were directors or officers of
	the registrant, and may, as to other persons, indemnify to the
	fullest extent permitted by law any person who was or is a
	party, or is threatened to be made a party, to any threatened,
	pending or completed action, suit or proceeding, whether civil,
	criminal, administrative or investigative, by reason of the fact
	II-1
 
	that he or she is or was a director, officer, employee or agent,
	or is or was serving at the request of the registrant as a
	director, officer, employee, trustee, fiduciary or agent of
	another corporation, partnership, joint venture, trust or other
	enterprise. This provision is applicable to all expenses
	(including attorneys fees and other expenses of
	litigation), judgments, fines, ERISA excise taxes or penalties
	and amounts paid in settlement actually and reasonably incurred
	in connection with such action, suit or proceeding. Expenses
	incurred by an officer or director in defending a civil or
	criminal action, suit or proceeding may be paid by the
	registrant in advance of the final disposition of such action,
	suit or proceeding, upon receipt of an undertaking by or on
	behalf of the director or officer to repay such amount if it
	shall ultimately be determined that he or she is not entitled to
	indemnification.
	 
	Restated
	Article R-VIII
	of the registrants Articles of Incorporation, as amended,
	provides that the directors of the registrant shall not be
	liable to the registrant or to the shareholders of the
	registrant for monetary damages for breach of fiduciary duties
	as a director, other than liability (i) for any breach of
	the directors duty of loyalty to the registrant or the
	shareholders of the registrant, (ii) for acts or omissions
	not in good faith or that involve intentional misconduct or a
	knowing violation of the law, (iii) under Section 8.65
	of the IBCA or (iv) for any transaction from which the
	director derived an improper personal benefit.
	 
	The indemnification provided for by Section 8.75 of the
	IBCA is not exclusive of any other rights to which those seeking
	indemnification or advancement of expenses may be entitled under
	any by-law, agreement, vote of shareholders or disinterested
	directors or otherwise, and a corporation may maintain insurance
	on behalf of any person who is or was a director, officer,
	employee or agent against liabilities for which indemnification
	is not expressly provided by the IBCA. The directors and
	officers of the registrant are insured under a directors and
	officers liability insurance policy maintained by the registrant.
	 
	Any underwriting agreements that the registrant may enter into
	will likely provide for the indemnification of the registrant,
	its controlling persons, its directors and certain of its
	officers by the underwriters against certain liabilities,
	including liabilities under the Securities Act of 1933.
	 
	 
	The exhibits to this registration statement are listed in the
	Exhibit Index to this registration statement, which
	Exhibit Index is hereby incorporated by reference.
	 
	 
	The undersigned registrant hereby undertakes:
	 
|  |  | 
| (1) | To file, during any period in which offers or sales are being
	made, a post-effective amendment to this registration statement: | 
	 
|  |  |  | 
|  | (i) | to include any prospectus required by Section 10(a)(3) of
	the Securities Act of 1933; | 
|  | 
|  | (ii) | to reflect in the prospectus any facts or events arising after
	the effective date of this registration statement (or the most
	recent post-effective amendment thereof) which, individually or
	in the aggregate, represent a fundamental change in the
	information set forth in this registration statement.
	Notwithstanding the foregoing, any increase or decrease in the
	volume of securities offered (if the total dollar value of
	securities offered would not exceed that which was registered)
	and any deviation from the low or high end of the estimated
	maximum offering range may be reflected in the form of
	prospectus filed with the Securities and Exchange Commission
	pursuant to Rule 424(b) if, in the aggregate, the changes
	in volume and price represent no more than a 20% change in the
	maximum aggregate offering price set forth in the
	Calculation of Registration Fee table in the
	effective registration statement; | 
	II-2
 
	 
|  |  |  | 
|  | (iii) | to include any material information with respect to the plan of
	distribution not previously disclosed in this registration
	statement or any material change to such information in this
	registration statement; | 
	 
	provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii)
	do not apply if the information required to be included in a
	post-effective amendment by those paragraphs is contained in
	periodic reports filed with or furnished to the Commission by
	the registrant pursuant to Section 13 or Section 15(d)
	of the Securities Exchange Act of 1934 that are incorporated by
	reference in this registration statement, or is contained in a
	form of prospectus filed pursuant to Rule 424(b) that is
	part of the registration statement.
	 
|  |  | 
| (2) | That, for the purpose of determining any liability under the
	Securities Act of 1933, each such post-effective amendment shall
	be deemed to be a new registration statement relating to the
	securities offered therein, and the offering of such securities
	at that time shall be deemed to be the initial
	bona fide
	offering thereof. | 
|  | 
| (3) | To remove from registration by means of a post-effective
	amendment any of the securities being registered which remain
	unsold at the termination of the offering. | 
|  | 
| (4) | That, for the purpose of determining liability under the
	Securities Act of 1933 to any purchaser: | 
	 
|  |  |  | 
|  | (i) | each prospectus filed by the registrant pursuant to Rule
	424(b)(3) shall be deemed to be part of the registration
	statement as of the date the filed prospectus was deemed part of
	and included in the registration statement; and | 
|  | 
|  | (ii) | each prospectus required to be filed pursuant to Rule 424(b)(2),
	(b)(5) or (b)(7) as part of a registration statement in reliance
	on Rule 430B relating to an offering made pursuant to Rule
	415(a)(1)(i), (vii) or (x) for the purpose of
	providing the information required by section 10(a) of the
	Securities Act of 1933 shall be deemed to be part of and
	included in the registration statement as of the earlier of the
	date such form of prospectus is first used after the
	effectiveness or the date of the first contract of sale of
	securities in the offering described in the prospectus. As
	provided in Rule 430B, for liability purposes of the issuer
	and any person that is at that date an underwriter, such date
	shall be deemed to be a new effective date of the registration
	statement relating to the securities in the registration
	statement to which that prospectus relates, and the offering of
	such securities at that time shall be deemed to be the initial
	bona fide
	offering thereof.
	Provided, however
	,
	that no statement made in a registration statement or prospectus
	that is part of the registration statement or made in a document
	incorporated or deemed incorporated by reference into the
	registration statement or prospectus that is part of the
	registration statement will, as to a purchaser with a time of
	contract of sale prior to such effective date, supersede or
	modify any statement that was made in the registration statement
	or prospectus that was part of the registration statement or
	made in any such document immediately prior to such effective
	date. | 
	 
|  |  | 
| (5) | That, for the purpose of determining liability of the registrant
	under the Securities Act of 1933 to any purchaser in the initial
	distribution of the securities, the undersigned registrant
	undertakes that in a primary offering of securities of the
	undersigned registrant pursuant to this registration statement,
	regardless of the underwriting method used to sell the
	securities to the purchaser, if the securities are offered or
	sold to such purchaser by means of any of the following
	communications, the undersigned registrant will be a seller to
	the purchaser and will be considered to offer or sell such
	securities to such purchaser: | 
	 
|  |  |  | 
|  | (i) | any preliminary prospectus or prospectus of the undersigned
	registrant relating to the offering required to be filed
	pursuant to Rule 424; | 
	II-3
 
	 
|  |  |  | 
|  | (ii) | any free writing prospectus relating to the offering prepared by
	or on behalf of the undersigned registrant or used or referred
	to by the undersigned registrant; | 
|  | 
|  | (iii) | the portion of any other free writing prospectus relating to the
	offering containing material information about the undersigned
	registrant or its securities provided by or on behalf of the
	undersigned registrant; and | 
|  | 
|  | (iv) | any other communication that is an offer in the offering made by
	the undersigned registrant to the purchaser. | 
	 
|  |  | 
| (6) | That, for purposes of determining any liability under the
	Securities Act of 1933, each filing of the registrants
	annual report pursuant to section 13(a) or section 15(d) of
	the Securities Exchange Act of 1934 (and, where applicable, each
	filing of an employee benefit plans annual report pursuant
	to section 15(d) of the Securities Exchange Act of
	1934) that is incorporated by reference in the registration
	statement shall be deemed to be a new registration statement
	relating to the securities offered therein, and the offering of
	such securities at that time shall be deemed to be the initial
	bona fide
	offering thereof. | 
|  | 
| (7) | Insofar as indemnification for liabilities arising under the
	Securities Act of 1933 may be permitted to directors,
	officers or persons controlling the registrant, the registrant
	has been informed that in the opinion of the Securities and
	Exchange Commission such indemnification is against public
	policy as expressed in the Securities Act of 1933 and is
	therefore unenforceable. In the event that a claim for
	indemnification against such liabilities (other than the payment
	by the registrant of expenses incurred or paid by a director,
	officer, or controlling person of the registrant in the
	successful defense of any action, suit or proceeding) is
	asserted by such director, officer or controlling person in
	connection with the securities being registered, the registrant
	will, unless in the opinion of its counsel the matter has been
	settled by controlling precedent, submit to a court of
	appropriate jurisdiction the question whether such
	indemnification by it is against public policy as expressed in
	the Securities Act of 1933 and will be governed by the final
	adjudication of such issue. | 
|  | 
| (8) | To file an application for the purpose of determining the
	eligibility of the trustee to act under Subsection (a) of
	Section 310 of the Trust Indenture Act in accordance with
	the rules and regulations prescribed by the Commission under
	Section 305(b)(2) of the Act. | 
	II-4
 
	SIGNATURES
	 
	Pursuant to the requirements of the Securities Act of 1933, the
	Registrant certifies that it has reasonable grounds to believe
	that it meets all of the requirements for filing on
	Form S-3
	and has duly caused this registration statement to be signed on
	its behalf by the undersigned, thereunto duly authorized, in the
	City of Deerfield, State of Illinois, on this 14th day of
	July, 2008.

	Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders
	of Securities of such series voting in favor thereof, either in person or by proxies duly appointed
	in writing, at any meeting of Holders of Securities of such series duly called and held in
	accordance with the provisions of Article Fifteen, or a combination of such instruments and any
	such record. Except as herein otherwise expressly provided, such action shall become effective
	when such instrument or instruments or record or both are delivered to the Trustee and, where it is
	hereby expressly required, to the Company. Such instrument or instruments and any such record (and
	the action embodied therein and evidenced thereby) are herein sometimes referred to as the Act of
	the Holders signing such instrument or instruments or so voting at any such meeting. Proof of
	execution of any such instrument or of a writing appointing any such agent, or of the holding by
	any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to
	Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and the Company and any
	agent of the Trustee or the Company, if made in the manner provided in this Section. The record of
	any meeting of Holders of Securities shall be proved in the manner provided in Section 15.6.
	     Without limiting the generality of this Section 1.4, unless otherwise provided in or pursuant
	to this Indenture, a Holder, including a U.S. Depositary that is a Holder of a global Security, may
	make, give or take, by a proxy or proxies duly appointed in writing, any request, demand,
	authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this
	Indenture to be made, given or taken by Holders, and a U.S. Depositary that is a Holder of a global
	Security may provide its proxy or proxies to the beneficial owners of interests in any such global
	Security through such U.S. Depositarys standing instructions and customary practices.
	     The Company shall fix a record date for the purpose of determining the Persons who are
	beneficial owners of interest in any permanent global Security held by a U.S. Depositary entitled
	under the procedures of such U.S. Depositary to make, give or take, by a proxy or proxies duly
	appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or
	other Act provided in or pursuant to this Indenture to be made, given or taken by Holders. If such
	a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies,
	and only such Persons, shall be entitled to make, give or take such request, demand, authorization,
	direction, notice, consent, waiver or other Act, whether or not such Holders remain Holders after
	such record date. No such request, demand, authorization, direction, notice, consent, waiver or
	other Act shall be valid or effective if made, given or taken more than 90 days after such record
	date.
	     (2) The fact and date of the execution by any Person of any such instrument or writing
	referred to in this Section 1.4 may be proved in any reasonable manner; and the Trustee may in any
	instance require further proof with respect to any of the matters referred to in this Section.
	13
 
	 
	     (3) The ownership, principal amount and serial numbers of Registered Securities held by any
	Person, and the date of the commencement and the date of the termination of holding the same, shall
	be proved by the Security Register.
	     (4) The ownership, principal amount and serial numbers of Bearer Securities held by any
	Person, and the date of the commencement and the date of the termination of holding the same, may
	be proved by the production of such Bearer Securities or by a certificate executed, as depositary,
	by any trust company, bank, banker or other depositary reasonably acceptable to the Company,
	wherever situated, if such certificate shall be deemed by the Company and the Trustee to be
	satisfactory, showing that at the date therein mentioned such Person had on deposit with such
	depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be
	proved by the certificate or affidavit of the Person holding such Bearer Securities, if such
	certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company
	may assume that such ownership of any Bearer Security continues until (i) another certificate or
	affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (ii)
	such Bearer Security is produced to the Trustee by some other Person, or (iii) such Bearer Security
	is surrendered in exchange for a Registered Security, or (iv) such Bearer Security is no longer
	Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the
	Person so executing such instrument or writing and the date of the commencement and the date of the
	termination of holding the same may also be proved in any other manner which the Company and the
	Trustee deem sufficient.
	     (5) If the Company shall solicit from the Holders of any Registered Securities any request,
	demand, authorization, direction, notice, consent, waiver or other Act, the Company may at its
	option (but is not obligated to), by Board Resolution, fix in advance a record date for the
	determination of Holders of Registered Securities entitled to give such request, demand,
	authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed,
	such request, demand, authorization, direction, notice, consent, waiver or other Act may be given
	before or after such record date, but only the Holders of Registered Securities of record at the
	close of business on such record date shall be deemed to be Holders for the purpose of determining
	whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or
	consented to such request, demand, authorization, direction, notice, consent, waiver or other Act,
	and for that purpose the Outstanding Securities shall be computed as of such record date; provided
	that no such authorization, agreement or consent by the Holders of Registered Securities shall be
	deemed effective unless it shall become effective pursuant to the provisions of this Indenture not
	later than six months after the record date.
	     (6) Any request, demand, authorization, direction, notice, consent, waiver or other Act by
	the Holder of any Security shall bind every future Holder of the same Security and the Holder of
	every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu
	thereof in respect of anything done or suffered to be done by the Trustee, any Security Registrar,
	any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made
	upon such Security.

| Section 1.5. |  | Notices, etc. to Trustee and Company. | 
 
	     Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders
	or other document provided or permitted by this Indenture to be made upon, given or furnished to,
	or filed with,
	     (1) the Trustee by any Holder or the Company shall be sufficient for every purpose
	hereunder if made, given, furnished or filed in writing (or by confirmed facsimile
	transmission to (312) 726-2158) to or with the Trustee at its Corporate Trust Office, or
	     (2) the Company by the Trustee or any Holder shall be sufficient for every purpose
	hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
	postage prepaid, to the Company addressed to the attention of its Treasurer, at the address
	of its principal office specified in the first paragraph of this Indenture or at any other
	address previously furnished in writing to the Trustee by the Company.
|  |  |  | 
| Section 1.6. |  | Notice to Holders of Securities; Waiver. | 
 
	     Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture
	provides for notice to Holders of Securities of any event,
	     (1) such notice shall be sufficiently given to Holders of Registered Securities if in
	writing and mailed, first-class postage prepaid, to each Holder of a Registered Security
	affected by such event, at his address as it appears in the Security Register, not later
	than the latest date, and not earlier than the earliest date, prescribed for the giving of
	such notice; and
	     (2) such notice shall be sufficiently given to Holders of Bearer Securities, if any,
	if published in an Authorized Newspaper in The City of New York and, if such Securities are
	then listed on any stock exchange outside the United States, in an Authorized Newspaper in
	such city as the Company shall advise the Trustee that such stock exchange so requires, on a
	Business Day at least twice, the first such publication to be not earlier than the earliest
	date and the second such publication to be not later than the latest date prescribed for the
	giving of such notice.
	     In any case where notice to Holders of Registered Securities is given by mail, neither the
	failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a
	Registered Security shall affect the sufficiency of such notice with respect to other Holders of
	Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as
	provided herein. Any notice which is mailed in the manner herein provided shall be conclusively
	presumed to have been duly given or provided. In the case by reason of the suspension of regular
	mail service or by reason of any other cause it shall be impracticable to give such notice by mail,
	then such notification as shall be made by any reasonable alternate method of delivery, with notice
	of such to be provided to the Trustee, shall constitute a sufficient notification for every purpose
	hereunder.
	15
 
	 
	     In case by reason of the suspension of publication of any Authorized Newspaper or Authorized
	Newspapers or by reason of any other cause it shall be impracticable to publish any notice to
	Holders of Bearers Securities as provided above, then such notification to Holders of Bearer
	Securities as shall be made by such reasonable alternate method of publication or notice, with
	notice of such to be provided to the Trustee, shall constitute sufficient notice to such Holders
	for every purpose hereunder. Neither failure to give notice by publication to Holders of Bearer
	Securities as provided above, nor any defect in any notice so published, shall affect the
	sufficiency of any notice mailed to Holders of Registered Securities as provided above.
	     Where this Indenture provides for notice in any manner, such notice may be waived in writing
	by the Person entitled to receive such notice, either before or after the event, and such waiver
	shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed
	with the Trustee, but such filing shall not be a condition precedent to the validity of any action
	taken in reliance upon such waiver.
|  |  |  | 
| Section 1.7. |  | Language of Notices. | 
 
	     Any request, demand, authorization, direction, notice, consent, election or waiver required or
	permitted under this Indenture shall be in the English language, except that, if the Company so
	elects, any published notice may be in an official language of the country of publication.
|  |  |  | 
| Section 1.8. |  | Conflict with Trust Indenture Act. | 
 
	     If any provision hereof limits, qualifies or conflicts with any duties under any required
	provision of the Trust Indenture Act imposed by operation of Section 318(c) thereof, such required
	provision shall control.
|  |  |  | 
| Section 1.9. |  | Effect of Headings and Table of Contents. | 
 
	     The Article and Section headings herein and the Table of Contents are for convenience only and
	shall not affect the construction hereof.
|  |  |  | 
| Section 1.10. |  | Successors and Assigns. | 
 
	     All covenants and agreements in this Indenture by the Company shall bind its successors and
	assigns, whether so expressed or not.
|  |  |  | 
| Section 1.11. |  | Separability Clause. | 
 
	     In case any provision in this Indenture, any Security or any Coupon shall be invalid, illegal
	or unenforceable, the validity, legality and enforceability of the remaining provisions shall not
	in any way be affected or impaired thereby.

|  |  |  | 
| Section 1.12. |  | Benefits of Indenture. | 
 
	     Nothing in this Indenture, any Security or any Coupon, express or implied, shall give to any
	Person, other than the parties hereto, any Security Registrar, any Paying Agent, any Authenticating
	Agent and their successors hereunder and the Holders of Securities or Coupons, any benefit or any
	legal or equitable right, remedy or claim under this Indenture.
|  |  |  | 
| Section 1.13. |  | Governing Law. | 
 
	     This Indenture, the Securities and any Coupons shall be governed by, construed and enforced in
	accordance with the laws of the State of New York applicable to agreements made or instruments
	entered into and, in each case, performed in said state.
|  |  |  | 
| Section 1.14. |  | Legal Holidays. | 
 
	     Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case
	where any Interest Payment Date, Stated Maturity or Maturity of any Security, or the last date on
	which a Holder has the right to convert or exchange Securities of a series that are convertible or
	exchangeable, shall be a Legal Holiday at any Place of Payment, then (notwithstanding any other
	provision of this Indenture, any Security or any Coupon other than a provision in any Security or
	Coupon that specifically states that such provision shall apply in lieu hereof) payment need not be
	made at such Place of Payment on such date, and such Securities need not be converted or exchanged
	on such date but such payment may be made, and such Securities may be converted or exchanged, on
	the next succeeding day that is a Business Day at such Place of Payment with the same force and
	effect as if made on the Interest Payment Date or at the Stated Maturity or Maturity or on such
	last day for conversion or exchange, and no interest shall accrue on the amount payable on such
	date or at such time for the period from and after such Interest Payment Date, Stated Maturity,
	Maturity or last day for conversion or exchange, as the case may be, to such next succeeding
	Business Day.
|  |  |  | 
| Section 1.15. |  | Counterparts. | 
 
	     This Indenture may be executed in several counterparts, each of which shall be an original and
	all of which shall constitute but one and the same instrument.
|  |  |  | 
| Section 1.16. |  | Judgment Currency. | 
 
	     The Company agrees, to the fullest extent that it may effectively do so under applicable law,
	that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum
	due in respect of the principal of, or premium or interest, if any, or Additional Amounts on the
	Securities of any series (the Required Currency) into a currency in which a judgment will be
	rendered (the Judgment Currency), the rate of exchange used shall be the rate at which in
	accordance with normal banking procedures the Trustee could purchase in The City of New York the
	requisite amount of the Required Currency with the Judgment Currency on the New York Banking Day
	preceding the day on which a final unappealable judgment is given and (b) its obligations under
	this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied
	by any tender, or any recovery pursuant to any judgment (whether or not
	17
 
	 
	entered in accordance with clause (a)), in any currency other than the Required Currency,
	except to the extent that such tender or recovery shall result in the actual receipt, by the payee,
	of the full amount of the Required Currency expressed to be payable in respect of such payments,
	(ii) shall be enforceable as an alternative or additional cause of action for the purpose of
	recovering in the Required Currency the amount, if any, by which such actual receipt shall fall
	short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be
	affected by judgment being obtained for any other sum due under this Indenture. For purposes of
	the foregoing, New York Banking Day means any day except a Saturday, Sunday or a legal holiday in
	The City of New York or a day on which banking institutions in The City of New York are authorized
	or obligated by law, regulation or executive order to be closed.

| Section 1.17. |  | No Security Interest Created. | 
 
	     Subject to the provisions of Section 10.5, nothing in this Indenture or in any Securities,
	express or implied, shall be construed to constitute a security interest under the Uniform
	Commercial Code or similar legislation, as now or hereafter enacted and in effect in any
	jurisdiction where property of the Company or its Subsidiaries is or may be located.
|  |  |  | 
| Section 1.18. |  | Limitation on Individual Liability. | 
 
	     No recourse under or upon any obligation, covenant or agreement contained in this Indenture or
	in any Security, or for any claim based thereon or otherwise in respect thereof, shall be had
	against any incorporator, shareholder, officer or director, as such, past, present or future, of
	the Company, either directly or through the Company, whether by virtue of any constitution, statute
	or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
	understood that this Indenture and the obligations issued hereunder are solely corporate
	obligations, and that no such personal liability whatever shall attach to, or is or shall be
	incurred by, the incorporators, shareholders, officers or directors, as such, of the Company, or

	of the obligations, covenants or agreements contained in this Indenture or in any Security or
	implied therefrom; and that any and all such personal liability of every name and nature, either at
	common law or in equity or by constitution or statute, of, and any and all such rights and claims
	against, every such incorporator, shareholder, officer or director, as such, because of the
	creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants

	such Securities are stated to be payable and the Currency in which such Securities or any of
	them are to be paid pursuant to such election, and any deletions from or modifications of or
	additions to the terms of this Indenture to provide for or to facilitate the issuance of
	Securities denominated or payable, at the election of the Company or a Holder thereof or
	otherwise, in a Foreign Currency;
	     (17) whether the amount of payments of principal of, any premium or interest on or any
	Additional Amounts with respect to such Securities may be determined with reference to an
	index, formula or other method or methods (which index, formula or method or methods may be
	based, without limitation, on one or more Currencies, commodities, equity securities, equity
	indices or other indices), and, if so, the terms and conditions upon which and the manner in
	which such amounts shall be determined and paid or payable;
	     (18) any deletions from, modifications of or additions to the Events of Default or
	covenants of the Company with respect to any of such Securities, whether or not such Events
	of Default or covenants are consistent with the Events of Default or covenants set forth
	herein;
	     (19) whether either or both of Section 4.2(2) relating to defeasance or Section 4.2(3)
	relating to covenant defeasance shall not be applicable to the Securities of such series, or
	any covenants in addition to those specified in Section 4.2(3) relating to the Securities of
	such series shall be subject to covenant of defeasance, and any deletions from, or
	modifications or additions to, the provisions of Article Four in respect of the Securities
	of such series;
	     (20) whether any of such Securities are to be issuable upon the exercise of warrants,
	and the time, manner and place for such Securities to be authenticated and delivered;
	     (21) if any of such Securities are to be issuable in global form and are to be
	issuable in definitive form (whether upon original issue or upon exchange of a temporary
	Security) only upon receipt of certain certificates or other documents or satisfaction of
	other conditions, the form and terms of such certificates, documents or conditions;
	     (22) if there is more than one Trustee, the identity of the Trustee and, if not the
	Trustee, the identity of each Security Registrar, Paying Agent or Authenticating Agent with
	respect to such Securities; and
	     (23) any other terms of such Securities and any other deletions from or modifications
	or additions to this Indenture in respect of such Securities.
	23
 
	 
	     All Securities of any one series and all Coupons, if any, appertaining to Bearer Securities of
	such series shall be substantially identical except as to Currency of payments due thereunder,
	denomination and the rate of interest thereon, or method of determining the rate of interest, if
	any, Maturity, and the date from which interest, if any, shall accrue and except as may otherwise
	be provided by the Company in or pursuant to the Board Resolution and set forth in the Officers
	Certificate or in any indenture or indentures supplemental hereto pertaining to such series of
	Securities. The terms of the Securities of any series may provide, without limitation, that the
	Securities shall be authenticated and delivered by the Trustee on original issue from time to time
	upon written order of persons designated in the Officers Certificate or supplemental indenture and
	that such persons are authorized to determine, consistent with such Officers Certificate or any
	applicable supplemental indenture, such terms and conditions of the Securities of such series as
	are specified in such Officers Certificate or supplemental indenture. All Securities of any one
	series need not be issued at the same time and, unless otherwise so provided, a series may be
	reopened for issuances of additional Securities of such series or to establish additional terms of
	such series of Securities. If a separate entity is named as a Trustee in connection with issuance
	of any series of Securities, the Company agrees to enter into a supplemental indenture in
	connection with such issuance.
	     If any of the terms of the Securities of any series shall be established by action taken by or
	pursuant to a Board Resolution, the Board Resolution shall be delivered to the Trustee at or prior
	to the delivery of the Officers Certificate setting forth the terms of such series.

| Section 3.2. |  | Currency; Denominations. | 
 
	     Unless otherwise provided in or pursuant to this Indenture, the principal of, any premium and
	interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars.
	Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in
	Dollars shall be issuable in registered form without Coupons in minimum denominations of $2,000 and
	integral multiples of $1,000 in excess thereof, and the Bearer Securities denominated in Dollars
	shall be issuable in the denomination of $5,000 and integral multiples thereof. Securities not
	denominated in Dollars shall be issuable in such denominations as are established with respect to
	such Securities in or pursuant to this Indenture.
|  |  |  | 
| Section 3.3. |  | Execution, Authentication, Delivery and Dating. | 
 
	     Securities shall be executed on behalf of the Company by its Chairman of the Board, the Chief
	Executive Officer, a President, its Chief Financial Officer, its Treasurer or a Vice President
	under its corporate seal reproduced thereon and attested by its Secretary or one of its Assistant
	Secretaries. Coupons shall be executed on behalf of the Company by the Treasurer or any Assistant
	Treasurer of the Company. The signature of any of these officers on the Securities or any Coupons
	appertaining thereto may be manual or facsimile.
	     Securities and any Coupons appertaining thereto bearing the manual or facsimile signatures of
	individuals who were at any time the proper officers of the Company shall bind the Company,
	notwithstanding that such individuals or any of them have ceased to hold such offices
	24
 
	 
	prior to the authentication and delivery of such Securities and Coupons or did not hold such
	offices at the date of original issuance of such Securities or Coupons.
	     At any time and from time to time after the execution and delivery of this Indenture, the
	Company may deliver Securities, together with any Coupons appertaining thereto, executed by the
	Company, to the Trustee for authentication and, provided that the Board Resolution and Officers
	Certificate or supplemental indenture or indentures with respect to such Securities referred to in
	Section 3.1 and a Company Order for the authentication and delivery of such Securities have been
	delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the
	provisions hereof and of such Securities shall authenticate and deliver such Securities. In
	authenticating such Securities, and accepting the additional responsibilities under this Indenture
	in relation to such Securities and any Coupons appertaining thereto, the Trustee shall be entitled
	to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be
	fully protected in relying upon,
	     (1) an Opinion of Counsel to the effect that:
	     (a) the form or forms and terms of such Securities and Coupons, if any, have been
	established in conformity with the provisions of this Indenture;
	     (b) all conditions precedent to the authentication and delivery of such Securities and
	Coupons, if any, appertaining thereto, have been complied with and that such Securities and
	Coupons, when completed by appropriate insertions, executed under the Companys corporate
	seal and attested by duly authorized officers of the Company, delivered by duly authorized
	officers of the Company to the Trustee for authentication pursuant to this Indenture, and
	authenticated and delivered by the Trustee and issued by the Company in the manner and
	subject to any conditions specified in such Opinion of Counsel, will constitute legally
	valid and binding obligations of the Company, enforceable against the Company in accordance
	with their terms, except as enforcement thereof may be subject to or limited by bankruptcy,
	insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent
	transfer or other similar laws relating to or affecting creditors rights generally, and
	subject to general principles of equity (regardless of whether enforcement is sought in a
	proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this
	Indenture; such Opinion of Counsel need express no opinion as to the availability of
	equitable remedies;
	     (c) all laws and requirements in respect of the execution and delivery by the Company
	of such Securities and Coupons, if any, have been complied with; and
	     (d) this Indenture has been qualified under the Trust Indenture Act; and
	     (2) an Officers Certificate stating that all conditions precedent to the execution,
	authentication and delivery of such Securities and Coupons, if any, appertaining thereto, have been
	complied with and that, to the best knowledge of the Persons executing such certificate, no event
	which is, or after notice or lapse of time would become, an Event of Default with respect to any of
	the Securities shall have occurred and be continuing.
	25
 
	 
	     If all the Securities of any series are not to be issued at one time, it shall not be
	necessary to deliver an Opinion of Counsel and an Officers Certificate at the time of issuance of
	each Security, but such opinion and certificate, with appropriate modifications, shall be delivered
	at or before the time of issuance of the first Security of such series. After any such first
	delivery, any separate written request by an Authorized Officer of the Company that the Trustee
	authenticate and deliver Securities of such series for original issue will be deemed to be a
	certification by the Company that all conditions precedent provided for in this Indenture relating
	to authentication and delivery of such Securities continue to have been complied with.
	     The Trustee shall not be required to authenticate or to cause an Authenticating Agent to
	authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect
	the Trustees own rights, duties or immunities under the Securities and this Indenture or otherwise
	in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by
	counsel, determines that such action may not lawfully be taken.
	     Each Registered Security shall be dated the date of its authentication. Each Bearer Security
	and any Bearer Security in global form shall be dated as of the date specified in or pursuant to
	this Indenture.
	     No Security or Coupon appertaining thereto shall be entitled to any benefit under this
	Indenture or be valid or obligatory for any purpose, unless there appears on such Security a
	certificate of authentication substantially in the form provided for in Section 2.2 or 6.11
	executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of
	one of its authorized officers. Such certificate upon any Security shall be conclusive evidence,
	and the only evidence, that such Security has been duly authenticated and delivered hereunder.
	Except as permitted by Section 3.6 or 3.7, the Trustee shall not authenticate and deliver any
	Bearer Security unless all Coupons appertaining thereto then matured have been detached and
	cancelled.
	     The Company initially appoints the Depository Trust Company (DTC) to act as Depository with
	respect to the global Securities.
	     The Company initially appoints the Trustee to act as the Securities Custodian for the global
	Securities.
|  |  |  | 
| Section 3.4. |  | Temporary Securities. | 
 
	     Pending the preparation of definitive Securities, the Company may execute and deliver to the
	Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided
	in Section 3.3, temporary Securities in lieu thereof which are printed, lithographed, typewritten,
	mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of
	the definitive Securities in lieu of which they are issued, in registered form or, if authorized in
	or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and with
	such appropriate insertions, omissions, substitutions and other variations as the officers of the
	Company executing such Securities may determine, as conclusively evidenced by their execution of
	such Securities. Such temporary Securities may be in global form.
	26
 
	 
	     Except in the case of temporary Securities in global form, which shall be exchanged in
	accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause
	definitive Securities to be prepared without unreasonable delay. After the preparation of
	definitive Securities of the same series and containing terms and provisions that are identical to
	those of any temporary Securities, such temporary Securities shall be exchangeable for such
	definitive Securities upon surrender of such temporary Securities at an Office or Agency for such
	Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or
	more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company
	shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal
	amount of definitive Securities of authorized denominations of the same series and containing
	identical terms and provisions;
	provided, however
	, that no definitive Bearer Security, except as
	provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary
	Registered Security; and
	provided, further
	, that a definitive Bearer Security shall be delivered in
	exchange for a temporary Bearer Security only in compliance with the conditions set forth in or
	pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with
	respect to a temporary global Security, until so exchanged the temporary Securities of any series
	shall in all respects be entitled to the same benefits under this Indenture as definitive
	Securities of such series.
|  |  |  | 
| Section 3.5. |  | Registration, Transfer and Exchange. | 
 
	     With respect to the Registered Securities of each series, if any, the Company shall cause to
	be kept a register (each such register being herein sometimes referred to as the Security
	Register) at an Office or Agency for such series in which, subject to such reasonable regulations
	as it may prescribe, the Company shall provide for the registration of the Registered Securities of
	such series and of transfers of the Registered Securities of such series. Such Office or Agency
	shall be the Security Registrar for that series of Securities. Unless otherwise specified in or
	pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar
	for each series of Securities. The Company shall have the right to remove and replace from time to
	time the Security Registrar for any series of Securities;
	provided
	that no such removal or
	replacement shall be effective until a successor Security Registrar with respect to such series of
	Securities shall have been appointed by the Company and shall have accepted such appointment by the
	Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with
	respect to a series of Securities, it shall have the right to examine the Security Register for
	such series at all reasonable times. There shall be only one Security Register for each series of
	Securities.
	     Upon surrender for registration of transfer of any Registered Security of any series at any
	Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and
	deliver, in the name of the designated transferee or transferees, one or more new Registered
	Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like
	aggregate principal amount bearing a number not contemporaneously outstanding and containing
	identical terms and provisions.
	     At the option of the Holder, Registered Securities of any series may be exchanged for other
	Registered Securities of the same series containing identical terms and provisions, in any
	27
 
	 
	authorized denominations, and of a like aggregate principal amount, upon surrender of the
	Securities to be exchanged at any Office or Agency for such series. Whenever any Registered
	Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall
	authenticate and deliver, the Registered Securities which the Holder making the exchange is
	entitled to receive.
	     If provided in or pursuant to this Indenture, with respect to Securities of any series, at the
	option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities
	of such series containing identical terms, denominated as authorized in or pursuant to this
	Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be
	exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured
	Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce
	any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be
	effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and
	the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the
	surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there
	is furnished to them such security or indemnity as they may require to save each of them and any
	Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to any
	Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such
	Holder shall be entitled to receive the amount of such payment;
	provided, however
	, that, except as
	otherwise provided in Section 10.2, interest represented by Coupons shall be payable only upon
	presentation and surrender of those Coupons at an Office or Agency for such series located outside
	the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is
	surrendered at any such Office or Agency for such series in exchange for a Registered Security of
	such series and like tenor after the close of business at such Office or Agency on (i) any Regular
	Record Date and before the opening of business at such Office or Agency on the next succeeding
	Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such
	Office or Agency on the related date for payment of Defaulted Interest, such Bearer Security shall
	be surrendered without the Coupon relating to such Interest Payment Date or proposed date of
	payment, as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such
	Coupon shall be returned to the Person so surrendering the Bearer Security), and interest or
	Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or
	proposed date for payment, as the case may be, in respect of the Registered Security issued in
	exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due
	in accordance with the provisions of this Indenture.
	     If provided in or pursuant to this Indenture with respect to Securities of any series, at the
	option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities
	upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to
	such series.
	     Whenever any Securities are surrendered for exchange as contemplated by the immediately
	preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate and
	deliver, the Securities which the Holder making the exchange is entitled to receive.
	28
 
	 
	     Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture,
	any global Security shall be exchangeable for definitive Securities only if (i) the Depositary is
	at any time unwilling, unable or ineligible to continue as Depositary and a successor Depositary is
	not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii)
	the Company executes and delivers to the Trustee a Company Order to the effect that such global
	Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with
	respect to the Securities and the Depositary requests the issuance of certificated notes. If the
	beneficial owners of interests in a global Security are entitled to exchange such interests for
	definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the
	preceding sentence, then without unnecessary delay but in any event not later than the earliest
	date on which such interests may be so exchanged, the Company shall deliver to the Trustee
	definitive Securities in such form and denominations as are required by or pursuant to this
	Indenture, and of the same series, containing identical terms and in aggregate principal amount
	equal to the principal amount of such global Security, executed by the Company. On or after the
	earliest date on which such interests may be so exchanged, such global Security shall be
	surrendered from time to time by the U.S. Depositary or such other Depositary as shall be
	specified in the Company Order with respect thereto, and in accordance with instructions given to
	the Trustee and the U.S. Depositary or such other Depositary, as the case may be (which
	instructions shall be in writing but need not be contained in or accompanied by an Officers
	Certificate or be accompanied by an Opinion of Counsel unless requested by the Trustee), as shall
	be specified in the Company Order with respect thereto to the Trustee, as the Companys agent for
	such purpose, to be exchanged, in whole or in part, for definitive Securities as described above
	without charge. The Trustee shall authenticate and make available for delivery, in exchange for
	such surrendered global Security or portion thereof, a like aggregate principal amount of
	definitive Securities of the same series of authorized denominations and of like tenor as such
	global Security or portion thereof to be exchanged, which (unless such Securities are not issuable
	both as Bearer Securities and as Registered Securities, in which case the definitive Securities
	exchanged for the global Security or portion thereof shall be issuable only in the form in which
	the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of
	Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by
	the beneficial owner thereof, but subject to the satisfaction of any certification or other
	requirements to the issuance of Bearer Securities;
	provided, however
	, that no such exchanges may
	occur during a period beginning at the opening of business 15 days before any selection of
	Securities of the same series to be redeemed and ending on the relevant Redemption Date; and
	provided, further
	, that (unless otherwise provided in or pursuant to this Indenture) no Bearer
	Security delivered in exchange for a portion of a global Security shall be mailed or otherwise
	delivered to any location in the United States. Promptly following any such exchange in part, such
	global Security shall be returned by the Trustee to such Depositary or the U.S. Depositary, as the
	case may be, or such other Depositary or U.S. Depositary referred to above in accordance with the
	instructions of the Company referred to above. If a Registered Security is issued in exchange for
	any portion of a global Security after the close of business at the Office or Agency for such
	Security where such exchange occurs on or after (i) any Regular Record Date for such Security and
	before the opening of business at such Office or Agency on the next succeeding Interest Payment
	Date, or (ii) any Special Record Date for such Security and before the opening of business at such
	Office or Agency on the related proposed date for
	29
 
	 
	payment of interest or Defaulted Interest, as the case may be, interest shall not be payable
	on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such
	Registered Security, but shall be payable on such Interest Payment Date or proposed date for
	payment, as the case may be, only to the Person to whom interest in respect of such portion of such
	global Security shall be payable in accordance with the provisions of this Indenture.
	     All Securities issued upon any registration of transfer or exchange of Securities shall be the
	valid obligations of the Company evidencing the same debt and entitling the Holders thereof to the
	same benefits under this Indenture as the Securities surrendered upon such registration of transfer
	or exchange.
	     Every Registered Security presented or surrendered for registration of transfer or for
	exchange or redemption shall (if so required by the Company or the Security Registrar for such
	Security) be duly endorsed, or be accompanied by a written instrument of transfer in form
	satisfactory to the Company and the Security Registrar for such Security duly executed by the
	Holder thereof or his attorney duly authorized in writing.
	     No service charge by the Company shall be made for any registration of transfer or exchange,
	or redemption of Securities, but the Company may require payment of a sum sufficient to cover any
	tax or other governmental charge and any other expenses (including fees and expenses of the
	Trustee) that may be imposed in connection with any registration of transfer or exchange of
	Securities, other than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.
	     Except as otherwise provided in or pursuant to this Indenture, the Company shall not be
	required (i) to issue, register the transfer of or exchange any Securities during a period
	beginning at the opening of business 15 days before the day of mailing of a notice of redemption of
	Securities of like tenor and the same series under Section 11.3 and ending at the close of business
	on the day of such mailing, or (ii) to register the transfer of or exchange any Registered Security
	selected for redemption in whole or in part, except in the case of any Security to be redeemed in
	part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security selected for
	redemption except, to the extent provided with respect to such Bearer Security, that such Bearer
	Security may be exchanged for a Registered Security of like tenor and the same series, provided
	that such Registered Security shall be immediately surrendered for redemption with written
	instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register
	the transfer of or exchange any Security which, in accordance with its terms, has been surrendered
	for repayment at the option of the Holder, except the portion, if any, of such Security not to be
	so repaid.
|  |  |  | 
| Section 3.6. |  | Mutilated, Destroyed, Lost and Stolen Securities. | 
 
	     If any mutilated Security or a Security with a mutilated Coupon appertaining to it is
	surrendered to the Trustee, subject to the provisions of this Section 3.6, the Company shall
	execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the
	same series containing identical terms and of like principal amount and bearing a number not
	30
 
	 
	contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons,
	if any, appertaining to the surrendered Security.
	     If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of
	the destruction, loss or theft of any Security or Coupon, and (ii) such security or indemnity as
	may be required by them to save each of them and any agent of either of them harmless, then, in the
	absence of notice to the Company or the Trustee that such Security or Coupon has been acquired by a
	bona fide purchaser, the Company shall execute and, upon the Companys request the Trustee shall
	authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
	stolen Security or in exchange for the Security to which a destroyed, lost or stolen Coupon
	appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
	series containing identical terms and of like principal amount and bearing a number not
	contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if
	any, appertaining to such destroyed, lost or stolen Security or to the Security to which such
	destroyed, lost or stolen Coupon appertains.
	     Notwithstanding the foregoing provisions of this Section 3.6, in case any mutilated,
	destroyed, lost or stolen Security or Coupon has become or is about to become due and payable, the
	Company in its discretion may, instead of issuing a new Security, pay such Security or Coupon;
	provided, however
	, that payment of principal of, any premium or interest on or any Additional
	Amounts with respect to any Bearer Securities shall, except as otherwise provided in Section 10.2,
	be payable only at an Office or Agency for such Securities located outside the United States and,
	unless otherwise provided in or pursuant to this Indenture, any interest on Bearer Securities and
	any Additional Amounts with respect to such interest shall be payable only upon presentation and
	surrender of the Coupons appertaining thereto.
	     Upon the issuance of any new Security under this Section 3.6, the Company may require the
	payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
	relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
	therewith.
	     Every new Security, with any Coupons appertaining thereto issued pursuant to this Section 3.6
	in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a
	destroyed, lost or stolen Coupon appertains shall constitute a separate obligation of the Company,
	whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the
	destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled
	to all the benefits of this Indenture equally and proportionately with any and all other Securities
	of such series and any Coupons, if any, duly issued hereunder.
	     The provisions of this Section 3.6, as amended or supplemented pursuant to this Indenture with
	respect to particular Securities or generally, shall be exclusive and shall preclude (to the extent
	lawful) all other rights and remedies with respect to the replacement or payment of mutilated,
	destroyed, lost or stolen Securities or Coupons.

|  |  |  | 
| Section 3.7. |  | Payment of Interest and Certain Additional Amounts; Rights to Interest and
	Certain Additional Amounts Preserved. | 
 
	     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
	Amounts with respect to any Registered Security which shall be payable, and are punctually paid or
	duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such
	Security (or one or more Predecessor Securities) is registered as of the close of business on the
	Regular Record Date for such interest.
	     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
	Amounts with respect to any Registered Security which shall be payable, but shall not be punctually
	paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called
	Defaulted Interest) shall forthwith cease to be payable to the Holder thereof on the relevant
	Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid
	by the Company, at its election in each case, as provided in Clause (1) or (2) below:
	     (1) The Company may elect to make payment of any Defaulted Interest to the Person in
	whose name such Registered Security (or a Predecessor Security thereof) shall be registered
	at the close of business on a Special Record Date for the payment of such Defaulted
	Interest, which shall be fixed by the Company in the following manner. The Company shall
	notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on
	such Registered Security, the Special Record Date therefor and the date of the proposed
	payment, and at the same time the Company shall deposit with the Trustee an amount of money
	equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or
	shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date
	of the proposed payment, such money when so deposited to be held in trust for the benefit of
	the Person entitled to such Defaulted Interest as in this Clause provided. The Special
	Record Date for the payment of such Defaulted Interest shall be not more than 15 days and
	not less than 10 days prior to the date of the proposed payment and not less than 10 days
	after notification to the Trustee of the proposed payment. The Trustee shall, in the name
	and at the expense of the Company, cause notice of the proposed payment of such Defaulted
	Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to
	the Holder of such Registered Security (or a Predecessor Security thereof) at his address as
	it appears in the Security Register not less than 10 days prior to such Special Record Date.
	The Trustee may, in its discretion, in the name and at the expense of the Company cause a
	similar notice to be published at least once in an Authorized Newspaper of general
	circulation in the Borough of Manhattan, The City of New York, but such publication shall
	not be a condition precedent to the establishment of such Special Record Date. Notice of
	the proposed payment of such Defaulted Interest and the Special Record Date therefor having
	been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name
	such Registered Security (or a Predecessor Security thereof) shall be registered at the
	close of business on such Special Record Date and shall no longer be payable pursuant to the
	following clause (2).
	32
 
	 
	     (2) The Company may make payment of any Defaulted Interest in any other lawful manner
	not inconsistent with the requirements of any securities exchange on which such Security may
	be listed, and upon such notice as may be required by such exchange, if, after notice given
	by the Company to the Trustee of the proposed payment pursuant to this Clause, such payment
	shall be deemed practicable by the Trustee.
	     Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular
	series pursuant to the provisions of this Indenture, at the option of the Company, interest on
	Registered Securities that bear interest may be paid by mailing a check to the address of the
	Person entitled thereto as such address shall appear in the Security Register or by transfer to an
	account maintained by the payee with a bank located in the United States.
	     Subject to the foregoing provisions of this Section and Section 3.5, each Security delivered
	under this Indenture upon registration of transfer of or in exchange for or in lieu of any other
	Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried
	by such other Security.
	     In the case of any Registered Security of any series that is convertible into shares of Common
	Stock or exchangeable for other securities, which Registered Security is converted or exchanged
	after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other
	than any Registered Security with respect to which the Stated Maturity is prior to such Interest
	Payment Date), interest with respect to which the Stated Maturity is on such Interest Payment Date
	shall be payable on such Interest Payment Date notwithstanding such conversion or exchange, and
	such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in
	whose name that Registered Security (or one or more predecessor Registered Securities) is
	registered at the close of business on such Regular Record Date. Except as otherwise expressly
	provided in the immediately preceding sentence, in the case of any Registered Security which is
	converted or exchanged, interest with respect to which the Stated Maturity is after the date of
	conversion or exchange of such Registered Security shall not be payable.
|  |  |  | 
| Section 3.8. |  | Persons Deemed Owners. | 
 
	     Prior to due presentment of a Registered Security for registration of transfer, the Company,
	the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such
	Registered Security is registered in the Security Register as the owner of such Registered Security
	for the purpose of receiving payment of principal of, any premium and (subject to Sections 3.5 and
	3.7) interest on and any Additional Amounts with respect to such Registered Security and for all
	other purposes whatsoever, whether or not any payment with respect to such Registered Security
	shall be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee
	shall be affected by notice to the contrary.
	     The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of
	any Bearer Security or the bearer of any Coupon as the absolute owner of such Security or Coupon
	for the purpose of receiving payment thereof or on account thereof and for all other purposes
	whatsoever, whether or not any payment with respect to such Security or Coupon shall
	33
 
	 
	be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee
	shall be affected by notice to the contrary.
	     No Holder of any beneficial interest in any global Security held on its behalf by a Depositary
	shall have any rights under this Indenture with respect to such global Security, and such
	Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee
	as the owner of such global Security for all purposes whatsoever. None of the Company, the
	Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for
	any aspect of the records relating to or payments made on account of beneficial ownership interests
	of a global Security or for maintaining, supervising or reviewing any records relating to such
	beneficial ownership interests.
|  |  |  | 
| Section 3.9. |  | Cancellation. | 
 
	     All Securities and Coupons surrendered for payment, redemption, registration of transfer,
	exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any
	Person other than the Trustee, be delivered to the Trustee, and any such Securities and Coupons, as
	well as Securities and Coupons surrendered directly to the Trustee for any such purpose, shall be
	cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for
	cancellation any Securities previously authenticated and delivered hereunder which the Company may
	have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly
	by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities
	cancelled as provided in this Section, except as expressly permitted by or pursuant to this
	Indenture. All cancelled Securities and Coupons held by the Trustee shall be disposed of in
	accordance with its customary procedures. Copies of all cancelled Securities shall be provided to
	the Company by the Trustee, promptly following cancellation of such Securities.
|  |  |  | 
| Section 3.10. |  | Computation of Interest. | 
 
	     Except as otherwise provided in or pursuant to this Indenture or in any Security, interest on
	the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.
	ARTICLE 4
	Satisfaction and Discharge of Indenture
|  |  |  | 
| Section 4.1. |  | Satisfaction and Discharge. | 
 
	     Upon the direction of the Company by a Company Order, this Indenture shall cease to be of
	further effect with respect to any series of Securities specified in such Company Order and any
	Coupons appertaining thereto, and the Trustee, on receipt of a Company Order, at the expense of the
	Company, shall execute proper instruments acknowledging satisfaction and discharge of this
	Indenture as to such series, when
	34
 
	 
	     (1) either
	     (a) all Securities of such series theretofore authenticated and delivered and all
	Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities of
	such series surrendered in exchange for Registered Securities of such series and maturing
	after such exchange whose surrender is not required or has been waived as provided in
	Section 3.5, (ii) Securities and Coupons of such series which have been destroyed, lost or
	stolen and which have been replaced or paid as provided in Section 3.6, (iii) Coupons
	appertaining to Securities of such series called for redemption and maturing after the
	relevant Redemption Date whose surrender has been waived as provided in Section 11.6, and
	(iv) Securities and Coupons of such series for whose payment money has theretofore been
	deposited in trust or segregated and held in trust by the Company and thereafter repaid to
	the Company or discharged from such trust, as provided in Section 10.3) have been delivered
	to the Trustee for cancellation; or
	     (b) all Securities of such series and, in the case of (i) or (ii) below, any Coupons
	appertaining thereto not theretofore delivered to the Trustee for cancellation
	     (i) have become due and payable, or
	     (ii) will become due and payable at their Stated Maturity within one year, or
	     (iii) if redeemable at the option of the Company, are to be called for
	redemption within one year under arrangements satisfactory to the Trustee for the
	giving of notice of redemption by the Trustee in the name, and at the expense, of
	the Company,
	and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be
	deposited with the Trustee as trust funds in trust for such purpose, money in the Currency
	in which such Securities are payable in an amount sufficient to pay the entire indebtedness
	on such Securities and any Coupons appertaining thereto not theretofore delivered to the
	Trustee for cancellation, including the principal of, any premium and interest on, any
	Additional Amounts with respect to such Securities, Interest to the date of deposit and any
	Coupons appertaining thereto, to the date of such deposit (in the case of Securities which
	have become due and payable), to Maturity or to the Redemption Date, as the case may be;
	     (2) the Company has paid or caused to be paid all other sums payable hereunder by the
	Company with respect to the Outstanding Securities of such series and any Coupons
	appertaining thereto; and
	     (3) the Company has delivered to the Trustee an Officers Certificate and an Opinion
	of Counsel, each stating that all conditions precedent herein provided for relating to the
	satisfaction and discharge of this Indenture as to such series have been complied with.
	35
 
	 
	     In the event there are Securities of two or more series hereunder, the Trustee shall be
	required to execute an instrument acknowledging satisfaction and discharge of this Indenture only
	if requested to do so with respect to Securities of such series as to which it is Trustee and if
	the other conditions thereto are met.
	     Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of
	Securities, the obligations of the Company to the Trustee under Section 6.6 and, if money shall
	have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the
	obligations of the Company and the Trustee with respect to the Securities of such series under
	Sections 3.5, 3.6, 4.3, 10.2 and 10.3, with respect to the payment of Additional Amounts, if any,
	with respect to such Securities as contemplated by Section 10.4 (but only to the extent that the
	Additional Amounts payable with respect to such Securities exceed the amount deposited in respect
	of such Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any rights to
	convert or exchange such Securities into Common Stock or other securities shall survive.
|  |  |  | 
| Section 4.2. |  | Defeasance and Covenant Defeasance. | 
 
	     (1) Unless pursuant to Section 3.1, either or both of (i) defeasance of the Securities of or
	within a series under clause (2) of this Section 4.2 shall not be applicable with respect to the
	Securities of such series or (ii) covenant defeasance of the Securities of or within a series under
	clause (3) of this Section 4.2 shall not be applicable with respect to the Securities of such
	series, then such provisions, together with the other provisions of this Section 4.2 (with such
	modifications thereto as may be specified pursuant to Section 3.1 with respect to any Securities),
	shall be applicable to such Securities and any Coupons appertaining thereto, and the Company may at
	its option by Board Resolution, at any time, with respect to such Securities and any Coupons
	appertaining thereto, elect to have Section 4.2(2) or Section 4.2(3) be applied to such Outstanding
	Securities and any Coupons appertaining thereto upon compliance with the conditions set forth below
	in this Section 4.2.
	     (2) Upon the Companys exercise of the above option applicable to this Section 4.2(2) with
	respect to any Securities of or within a series, the Company shall be deemed to have been
	discharged from its obligations with respect to such Outstanding Securities and any Coupons
	appertaining thereto on the date the conditions set forth in clause (4) of this Section 4.2 are
	satisfied (hereinafter, defeasance). For this purpose, such defeasance means that the Company
	shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding
	Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be
	Outstanding only for the purposes of clause (5) of this Section 4.2 and the other Sections of
	this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other
	obligations under such Securities and any Coupons appertaining thereto and this Indenture insofar
	as such Securities and any Coupons appertaining thereto are concerned (and the Trustee, at the
	expense of the Company, shall execute proper instruments acknowledging the same), except for the
	following which shall survive until otherwise terminated or discharged hereunder: (i) the rights
	of Holders of such Outstanding Securities and any Coupons appertaining thereto to receive, solely
	from the trust fund described in clause (4) of this Section 4.2 and as more fully set forth in such
	clause, payments in respect of the principal of (and premium, if any) and interest, if
	36
 
	 
	any, on, and Additional Amounts, if any, with respect to, such Securities and any Coupons
	appertaining thereto when such payments are due, and any rights of such Holder to convert such
	Securities into Common Stock or exchange such Securities for other securities, (ii) the obligations
	of the Company and the Trustee with respect to such Securities under Sections 3.5, 3.6, 10.2 and
	10.3 and with respect to the payment of Additional Amounts, if any, on such Securities as
	contemplated by Section 10.4 (but only to the extent that the Additional Amounts payable with
	respect to such Securities exceed the amount deposited in respect of such Additional Amounts
	pursuant to Section 4.2(4)(a) below), and with respect to any rights to convert such Securities
	into Common Stock or exchange such Securities for other securities, (iii) the rights, powers,
	trusts, duties and immunities of the Trustee hereunder and (iv) this Section 4.2. The Company may
	exercise its option under this Section 4.2(2) notwithstanding the prior exercise of its option
	under clause (3) of this Section 4.2 with respect to such Securities and any Coupons appertaining
	thereto.
	     (3) Upon the Companys exercise of the option to have this Section 4.2(3) apply with respect
	to any Securities of or within a series, the Company shall be released from its obligations under
	Section 8.1, Section 10.5 and Section 10.6, and, to the extent specified pursuant to Section
	3.1(19), any other covenant applicable to such Securities, with respect to such Outstanding
	Securities and any Coupons appertaining thereto on and after the date the conditions set forth in
	clause (4) of this Section 4.2 are satisfied (hereinafter, covenant defeasance), and such
	Securities and any Coupons appertaining thereto shall thereafter be deemed to be not Outstanding
	for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the
	consequences of any thereof) in connection with any such covenant, but shall continue to be deemed
	Outstanding for all other purposes hereunder. For this purpose, such covenant defeasance means
	that, with respect to such Outstanding Securities and any Coupons appertaining thereto, the Company
	may omit to comply with, and shall have no liability in respect of, any term, condition or
	limitation set forth in any such Section or such other covenant, whether directly or indirectly, by
	reason of any reference elsewhere herein to any such Section or such other covenant or by reason of
	reference in any such Section or such other covenant to any other provision herein or in any other
	document and such omission to comply shall not constitute a default or an Event of Default under
	Section 5.1(4) or otherwise, as the case may be, but, except as specified above, the remainder of
	this Indenture and such Securities and Coupons appertaining thereto shall be unaffected thereby.
	     (4) The following shall be the conditions to application of clause (2) or (3) of this Section
	4.2 to any Outstanding Securities of or within a series and any Coupons appertaining thereto:
	     (a) The Company shall irrevocably have deposited or caused to be deposited with the
	Trustee (or another trustee satisfying the requirements of Section 6.7 who shall agree to
	comply with the provisions of this Section 4.2 applicable to it) as trust funds in trust for
	the purpose of making the following payments, specifically pledged as security for, and
	dedicated solely to, the benefit of the Holders of such Securities and any Coupons
	appertaining thereto, (1) an amount in Dollars or in such Foreign Currency in which such
	Securities and any Coupons appertaining thereto are then specified as payable, or (2)
	Government Obligations which through the scheduled payment of
	37
 
	 
	principal and interest in respect thereof in accordance with their terms will provide,
	not later than one day before the due date of any payment of principal of (and premium, if
	any) and interest, if any, on such Securities and any Coupons appertaining thereto, money in
	an amount, or (3) a combination thereof, in any case, in an amount, sufficient, without
	consideration of any reinvestment of such principal and interest, in the opinion of a
	nationally recognized firm of Independent Public Accountants expressed in a written
	certification thereof delivered to the Trustee, to pay and discharge, and which shall be
	applied by the Trustee (or other qualifying trustee) to pay and discharge, (y) the principal
	of (and premium, if any) and interest, if any, on such Outstanding Securities and any
	Coupons appertaining thereto at the Stated Maturity of such principal or installment of
	principal or premium or interest (including any Redemption Date that the Company irrevocably
	specifies at the time of such defeasance or covenant defeasance) and (z) any mandatory
	sinking fund payments or analogous payments applicable to such Outstanding Securities and
	any Coupons appertaining thereto on the days on which such payments are due and payable in
	accordance with the terms of this Indenture and of such Securities and any Coupons
	appertaining thereto.
	     (b) Such defeasance or covenant defeasance shall not result in a breach or violation
	of, or constitute a default under, this Indenture or any other material agreement or
	instrument to which the Company is a party or by which it is bound.
	     (c) No Event of Default or event which with notice or lapse of time or both would
	become an Event of Default with respect to such Securities and any Coupons appertaining
	thereto shall have occurred and be continuing on the date of such deposit and, with respect
	to defeasance only, at any time during the period ending on the 91st day after the date of
	such deposit (it being understood that this condition shall not be deemed satisfied until
	the expiration of such period).
	     (d) In the case of an election under clause (2) of this Section 4.2, the Company shall
	have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has
	received from the Internal Revenue Service a letter ruling, or there has been published by
	the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this
	Indenture, there has been a change in the applicable Federal income tax law, in either case
	to the effect that, and based thereon such opinion shall confirm that, the Holders of such
	Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain
	or loss for Federal income tax purposes as a result of such defeasance and will be subject
	to Federal income tax on the same amounts, in the same manner and at the same times as would
	have been the case if such defeasance had not occurred.
	     (e) In the case of an election under clause (3) of this Section 4.2, the Company shall
	have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such
	Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain
	or loss for Federal income tax purposes as a result of such covenant defeasance and will be
	subject to Federal income tax on the same amounts, in the same
	38
 
	 
	manner and at the same times as would have been the case if such covenant defeasance
	had not occurred.
	     (f) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect
	that, after the 91st day after the date of deposit, all money and Government Obligations (or
	other property as may be provided pursuant to Section 3.1) (including the proceeds thereof)
	deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant
	to this clause (4) to be held in trust will not be subject to any case or proceeding
	(whether voluntary or involuntary) in respect of the Company under any Federal or State
	bankruptcy, insolvency, reorganization or other similar law, or any decree or order for
	relief in respect of the Company issued in connection therewith.
	     (g) The Company shall have delivered to the Trustee an Officers Certificate and an
	Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant
	defeasance under clause (2) or (3) of this Section 4.2 (as the case may be) have been
	complied with.
	     (h) Notwithstanding any other provisions of this Section 4.2(4), such defeasance or
	covenant defeasance shall be effected in compliance with any additional or substitute terms,
	conditions or limitations which may be imposed on the Company in connection therewith
	pursuant to Section 3.1.
	     (5) Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a
	deposit referred to in Section 4.2(4)(a) has been made, (a) the Holder of a Security in respect of
	which such deposit was made is entitled to, and does, elect pursuant to Section 3.1 or the terms of
	such Security to receive payment in a Currency other than that in which the deposit pursuant to
	Section 4.2(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in
	respect of the Foreign Currency in which the deposit pursuant to Section 4.2(4)(a) has been made,
	the indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed
	to have been, and will be, fully discharged and satisfied through the payment of the principal of
	(and premium, if any), and interest, if any, on, and Additional Amounts, if any, with respect to,
	such Security as the same becomes due out of the proceeds yielded by converting (from time to time
	as specified below in the case of any such election) the amount or other property deposited in
	respect of such Security into the Currency in which such Security becomes payable as a result of
	such election or Conversion Event based on (x) in the case of payments made pursuant to clause (a)
	above, the applicable market exchange rate for such Currency in effect on the second Business Day
	prior to each payment date, or (y) with respect to a Conversion Event, the applicable market
	exchange rate for such Foreign Currency in effect (as nearly as feasible) at the time of the
	Conversion Event.
	     The Company shall pay and indemnify the Trustee (or other qualifying trustee, collectively for
	purposes of this Section 4.2(5) and Section 4.3, the Trustee) against any tax, fee or other
	charge, imposed on or assessed against the Government Obligations deposited pursuant to this
	Section 4.2 or the principal or interest received in respect thereof other than any such tax, fee
	or other charge which by law is for the account of the Holders of such Outstanding Securities and
	any Coupons appertaining thereto.
	39
 
	 
	     Anything in this Section 4.2 to the contrary notwithstanding, the Trustee shall deliver or pay
	to the Company from time to time upon Company Request any money or Government Obligations (or other
	property and any proceeds therefrom) held by it as provided in clause (4) of this Section 4.2
	which, in the opinion of a nationally recognized firm of Independent Public Accountants expressed
	in a written certification thereof delivered to the Trustee, are in excess of the amount thereof
	which would then be required to be deposited to effect a defeasance or covenant defeasance, as
	applicable, in accordance with this Section 4.2.
	     In the case where an election is made under clause (3) of this Section 4.2 with respect to a
	Security and the Security is declared due and payable because of the occurrence of any Event of
	Default (other than an Event of Default with respect to any covenant as to which there has been
	covenant defeasance), if the amount in Dollars or Foreign Currency in which the Security is
	payable, and Government Obligations on deposit with the Trustee, will be sufficient to pay amounts
	due on the Security at the time of the stated maturity or earlier redemption but is not sufficient
	to pay amounts due on the Security at the time of the acceleration resulting from the Event of
	Default, the Company shall remain liable to make payment of the amounts due at the time of
	acceleration.
|  |  |  | 
| Section 4.3. |  | Application of Trust Money. | 
 
	     Subject to the provisions of the last paragraph of Section 10.3, all money and Government
	Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds
	thereof) deposited with the Trustee pursuant to Section 4.1 or 4.2 in respect of any Outstanding
	Securities of any series and any Coupons appertaining thereto shall be held in trust and applied by
	the Trustee, in accordance with the provisions of such Securities and any Coupons appertaining
	thereto and this Indenture, to the payment, either directly or through any Paying Agent (including
	the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such
	Securities and any Coupons appertaining thereto of all sums due and to become due thereon in
	respect of principal (and premium, if any) and interest and Additional Amounts, if any; but such
	money and Government Obligations need not be segregated from other funds except to the extent
	required by law.
	ARTICLE 5

| Section 5.1. |  | Events of Default. | 
 
	     Event of Default, wherever used herein with respect to Securities of any series, means any
	one of the following events (whatever the reason for such Event of Default and whether it shall be

	effect to any applicable grace period) or shall result in such Debt in principal amount in excess
	of $100 million becoming or being declared due and payable prior to the date on which it would
	otherwise become due and payable; provided, however, that if such default under such mortgage,
	indenture or instrument is cured by the Company, or waived by the holders of such Debt, in each
	case as many be permitted by such mortgage, indenture or instrument, then the event of default

| Section 5.2. |  | Acceleration of Maturity; Rescission and Annulment. | 
 
	     If an Event of Default with respect to Securities of any series at the time Outstanding (other
	than an Event of Default specified in clause (6) or (7) of Section 5.1) occurs and is continuing
	either the Trustee or the Holders of not less than 25% in principal amount of the Outstanding
	Securities of such series may declare the principal amount of all the Securities of such series, or
	such lesser amount as may be provided for in the Securities of such series, to be due and payable
	immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders),
	and upon any such declaration such principal or such lesser amount shall become immediately due and
	payable.
	     If an Event of Default specified in clause (6) or (7) of Section 5.1 occurs, all unpaid
	principal of and accrued interest on the Outstanding Securities of that series (or such lesser
	amount as may be provided for in the Securities of such series) shall
	ipso facto
	become and be
	immediately due and payable without any declaration or other act on the part of the Trustee or any
	Holder of any Security of that series.
	     At any time after a declaration of acceleration with respect to the Securities of any series
	has been made and before a judgment or decree for payment of the money due has been obtained by the
	Trustee as hereinafter in this Article provided, the Holders of not less than a majority in
	principal amount of the Outstanding Securities of such series, by written notice to the Company and
	the Trustee, may rescind and annul such declaration and its consequences if
	42
 
	 
	     (1) the Company has paid or deposited with the Trustee a sum of money sufficient to pay
	     (a) all overdue installments of any interest on and Additional Amounts with respect to
	all Securities of such series and any Coupon appertaining thereto,
	     (b) the principal of and any premium on any Securities of such series which have become
	due otherwise than by such declaration of acceleration and interest thereon and any
	Additional Amounts with respect thereto at the rate or rates borne by or provided for in
	such Securities,
	     (c) to the extent that payment of such interest or Additional Amounts is lawful,
	interest upon overdue installments of any interest and Additional Amounts at the rate or
	rates borne by or provided for in such Securities, and
	     (d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
	expenses, disbursements and advances of the Trustee, its agents and counsel and all other
	amounts due the Trustee under Section 6.6; and
	     (2) all Events of Default with respect to Securities of such series, other than the
	non-payment of the principal of, any premium and interest on, and any Additional Amounts with
	respect to Securities of such series which shall have become due solely by such declaration of
	acceleration, shall have been cured or waived as provided in Section 5.13.
	     No such rescission shall affect any subsequent default or impair any right consequent thereon.
|  |  |  | 
| Section 5.3. |  | Collection of Indebtedness and Suits for Enforcement by Trustee. | 
 
	     The Company covenants that if
	     (1) default is made in the payment of any installment of interest on or any Additional
	Amounts with respect to any Security or any Coupon appertaining thereto when such interest or
	Additional Amounts shall have become due and payable and such default continues for a period of 30
	days, or
	     (2) default is made in the payment of the principal of or any premium on any Security or any
	Additional Amounts with respect thereto at their Maturity,
	the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders
	of such Securities and any Coupons appertaining thereto, the whole amount of money then due and
	payable with respect to such Securities and any Coupons appertaining thereto, with interest upon
	the overdue principal, any premium and, to the extent that payment of such interest shall be
	legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate
	or rates borne by or provided for in such Securities, and, in addition thereto, such further amount
	of money as shall be sufficient to cover the costs and expenses of collection, including the
	reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
	counsel and all other amounts due to the Trustee under Section 6.6.
	43
 
	 
	     If the Company fails to pay the money it is required to pay the Trustee pursuant to the
	preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as
	trustee of an express trust, may institute a judicial proceeding for the collection of the money so
	due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the
	same against the Company or any other obligor upon such Securities and any Coupons appertaining
	thereto and collect the monies adjudged or decreed to be payable in the manner provided by law out
	of the property of the Company or any other obligor upon such Securities and any Coupons
	appertaining thereto, wherever situated.
	     If an Event of Default with respect to Securities of any series occurs and is continuing with
	respect to Securities of any series at the time Outstanding, the Trustee may in its discretion
	proceed to protect and enforce its rights and the rights of the Holders of Securities of such
	series and any Coupons appertaining thereto by such appropriate judicial proceedings as the Trustee
	shall deem most effectual to protect and enforce any such rights, whether for the specific
	enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the
	exercise of any power granted herein or therein, or to enforce any other proper remedy.

| Section 5.4. |  | Trustee May File Proofs of Claim. | 
 
	     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
	reorganization, arrangement, adjustment, composition or other similar judicial proceeding relative
	to the Company or any other obligor upon the Securities of any series or the property of the
	Company or such other obligor or their creditors, the Trustee (irrespective of whether the
	principal of the Securities shall then be due and payable as therein expressed or by declaration or
	otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the
	payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and
	empowered, by intervention in such proceeding or otherwise,
	     (1) to file and prove a claim for the whole amount, or such lesser amount as may be
	provided for in the Securities of any applicable series, of the principal and any premium,
	interest and Additional Amounts owing and unpaid in respect of the Securities and any
	Coupons appertaining thereto and to file such other papers or documents as may be necessary
	or advisable in order to have the claims of the Trustee (including any claim for the
	reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or
	counsel) and of the Holders of Securities or any Coupons appertaining thereto allowed in
	such judicial proceeding, and
	     (2) to collect and receive any monies or other property payable or deliverable on any
	such claims and to distribute the same subject to this Indenture;
	and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
	in any such judicial proceeding is hereby authorized by each Holder of Securities or any Coupons to
	make such payments to the Trustee and, in the event that the Trustee shall consent to the making of
	such payments directly to the Holders of Securities or any Coupons, to pay to the Trustee any
	amount due to it for the reasonable compensation, expenses, disbursements and
	44
 
	 
	advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section
	6.6.
	     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
	or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization,
	arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any
	Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a
	Security or any Coupon in any such proceeding.
|  |  |  | 
| Section 5.5. |  | Trustee May Enforce Claims without Possession of Securities or Coupons. | 
 
	     All rights of action and claims under this Indenture or any of the Securities or Coupons may
	be prosecuted and enforced by the Trustee without the possession of any of the Securities or
	Coupons or the production thereof in any proceeding relating thereto, and any such proceeding
	instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
	recovery or judgment, after provision for the payment of the reasonable compensation, expenses,
	disbursements and advances of the Trustee, its agents and counsel, shall be for the ratable benefit
	of each and every Holder of the Securities or Coupons in respect of which such judgment has been
	recovered.
|  |  |  | 
| Section 5.6. |  | Application of Money Collected. | 
 
	     Any money or other property collected by the Trustee pursuant to this Article shall be applied
	in the following order, at the date or dates fixed by the Trustee and, in case of the distribution
	of such money or other property on account of principal, or any premium, interest or Additional
	Amounts, upon presentation of the Securities or Coupons, or both, as the case may be, and the
	notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:
	     FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee, its
	agents and attorneys under Section 6.6, including payment of all compensation, expense and
	liabilities incurred, and all advances made by the Trustee, and the costs and expenses of

| Section 5.7. |  | Limitations on Suits. | 
 
	     No Holder of any Security of any series or any Coupons appertaining thereto shall have any
	right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for
	the appointment of a receiver or trustee, or for any other remedy hereunder, unless
	     (1) such Holder has previously given written notice to the Trustee of a continuing
	Event of Default with respect to the Securities of such series;
	     (2) the Holders of not less than 25% in principal amount of the Outstanding Securities
	of such series shall have made written request to the Trustee to institute proceedings in
	respect of such Event of Default in its own name as Trustee hereunder;
	     (3) such Holder or Holders have offered to the Trustee such indemnity as is reasonably
	satisfactory to it against the costs, expenses and liabilities to be incurred in compliance
	with such request;
	     (4) the Trustee for 60 days after its receipt of such notice, request and offer of
	indemnity has failed to institute any such proceeding; and
	     (5) no direction inconsistent with such written request has been given to the Trustee
	during such 60-day period by the Holders of a majority in principal amount of the
	Outstanding Securities of such series;
	it being understood and intended that no one or more of such Holders shall have any right in any
	manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to
	affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any
	other series, or to obtain or to seek to obtain priority or preference over any other Holders or to
	enforce any right under this Indenture, except in the manner herein provided and for the equal and
	ratable benefit of all such Holders.
|  |  |  | 
| Section 5.8. |  | Unconditional Right of Holders to Receive Principal and any Premium, Interest
	and Additional Amounts. | 
 
	     Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon
	shall have the right, which is absolute and unconditional, to receive payment of the principal of,
	any premium and (subject to Sections 3.5 and 3.7) interest on, and any Additional Amounts with
	respect to such Security or payment of such Coupon, as the case may be, on the respective Stated
	Maturity or Maturities therefor specified in such Security or Coupon (or, in the case of
	redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if
	provided in or pursuant to this Indenture, on the date such repayment is due) and to institute suit
	for the enforcement of any such payment, and such right shall not be impaired without the consent
	of such Holder.

| Section 5.9. |  | Restoration of Rights and Remedies. | 
 
	     If the Trustee or any Holder of a Security or a Coupon has instituted any proceeding to
	enforce any right or remedy under this Indenture and such proceeding has been discontinued or
	abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then
	and in every such case the Company, the Trustee and each such Holder shall, subject to any
	determination in such proceeding, be restored severally and respectively to their former positions
	hereunder, and thereafter all rights and remedies of the Trustee and each such Holder shall
	continue as though no such proceeding had been instituted.
|  |  |  | 
| Section 5.10. |  | Rights and Remedies Cumulative. | 
 
	     Except as otherwise provided with respect to the replacement or payment of mutilated,
	destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 3.6, no right or
	remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security
	or a Coupon is intended to be exclusive of any other right or remedy, and every right and remedy,
	to the extent permitted by law, shall be cumulative and in addition to every other right and remedy
	given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
	employment of any right or remedy hereunder, or otherwise, shall not, to the extent permitted by
	law, prevent the concurrent assertion or employment of any other appropriate right or remedy.
|  |  |  | 
| Section 5.11. |  | Delay or Omission Not Waiver. | 
 
	     No delay or omission of the Trustee or of any Holder of any Security or Coupon to exercise any
	right or remedy accruing upon any Event of Default shall impair any such right or remedy or
	constitute a waiver of any such Event of Default or an acquiescence therein. Every right and
	remedy given by this Article or by law to the Trustee or to any Holder of a Security or a Coupon
	may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by
	such Holder, as the case may be.
|  |  |  | 
| Section 5.12. |  | Control by Holders of Securities. | 
 
	     The Holders of a majority in principal amount of the Outstanding Securities of any series
	shall have the right to direct the time, method and place of conducting any proceeding for any
	remedy available to the Trustee or exercising any trust or power conferred on the Trustee with
	respect to the Securities of such series and any Coupons appertaining thereto, provided that
	     (1) such direction shall not be in conflict with any rule of law or with this
	Indenture or with the Securities of such series,
	     (2) the Trustee may take any other action deemed proper by the Trustee which is not
	inconsistent with such direction, and
	     (3) such direction is not unduly prejudicial to the rights of the other Holders of
	Securities of such series not joining in such action or that may involve the Trustee in
	personal liability.
	47
 
	 
|  |  |  | 
| Section 5.13. |  | Waiver of Past Defaults. | 
 
	     The Holders of not less than a majority in principal amount of the Outstanding Securities of
	any series on behalf of the Holders of all the Securities of such series and any Coupons
	appertaining thereto may waive any past default hereunder with respect to such series and its
	consequences, except a default
	     (1) in the payment of the principal of, any premium or interest on, or any Additional
	Amounts with respect to, any Security of such series or any Coupons appertaining thereto, or
	     (2) in respect of a covenant or provision hereof which under Article Nine cannot be
	modified or amended without the consent of the Holder of each Outstanding Security of such
	series affected.
	     The Company may, but shall not be obligated to, fix a record date for the purpose of
	determining the Persons entitled to waive any past default hereunder. If a record date is fixed,
	the Holders on such record date, or their duly designated proxies, and only such Persons, shall be
	entitled to waive any default hereunder, or to retract (prior to the requisite percentage for such
	waiver to become effective having been obtained) any such waiver previously given, whether or not
	such Holders remain Holders after such record date; provided, that such waiver shall be effected no
	later than the 90
	th
	day after such record date.
	     Upon any such waiver, such default shall cease to exist, and any Event of Default arising
	therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
	waiver shall extend to any subsequent or other default or impair any right consequent thereon.
|  |  |  | 
| Section 5.14. |  | Waiver of Usury, Stay or Extension Laws. | 
 
	     The Company covenants that (to the extent that it may lawfully do so) it will not at any time
	insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any
	usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may
	affect the covenants or the performance of this Indenture; and the Company expressly waives (to the
	extent that it may lawfully do so) all benefit or advantage of any such law and covenants that it
	will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will
	suffer and permit the execution of every such power as though no such law had been enacted.
|  |  |  | 
| Section 5.15. |  | Undertaking for Costs | 
 
	     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
	shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
	enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
	action taken or omitted by it as Trustee, the filing by any party litigant in such suit of any
	undertaking to pay the costs of such suit, and that such court may in its discretion assess
	reasonable costs, including reasonable attorneys fees, against any party litigant in such suit
	having due regard to the merits and good faith of the claims or defenses made by such party
	48
 
	 
	litigant; but the provisions of this Section 5.15 shall not apply to any suit instituted by
	the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate
	more than 10% in principal amount of Outstanding Securities of any series, or to any suit
	instituted by any Holder for the enforcement of the payment of the principal of (or premium, if
	any) or interest, if any, on or Additional Amounts, if any, with respect to any Security on or
	after the respective Stated Maturities expressed in such Security (or, in the case of redemption,
	on or after the Redemption Date, and, in the case of repayment, on or after the date for repayment)
	or for the enforcement of the right, if any, to convert or exchange any Security into Common Stock
	or other securities in accordance with its terms.

	premium or interest on or any Additional Amounts with respect to particular Securities or any
	Coupons appertaining thereto.
	     To the extent permitted by law, any compensation or expense incurred by the Trustee after a
	default specified in or pursuant to Section 5.1 is intended to constitute an expense of
	administration under any then applicable bankruptcy or insolvency law. Trustee for purposes of
	this Section 6.6 shall include any predecessor Trustee but the negligence or bad faith of any
	Trustee shall not affect the rights of any other Trustee under this Section 6.6.

	effect to the Trustee in its capacity as Authenticating Agent, Paying Agent or Security Registrar.

	accordance with the provisions of this Section, it shall resign immediately in the manner and with

	successor Trustee pursuant to Section 6.9.
	     (2) The Trustee may resign at any time with respect to the Securities of one or more series
	by giving written notice thereof to the Company. If the instrument of acceptance by a successor

	insolvent or a receiver of the Trustee or of its property shall be appointed or any public

	     (5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
	shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
	series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor
	Trustee or Trustees with respect to the Securities of such series (it being understood that any
	such successor Trustee may be appointed with respect to the Securities of one or more or all of
	such series and that at any time there shall be only one Trustee with respect to the Securities of
	any particular series) and shall comply with the applicable requirements of Section 6.9. If,
	within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a
	successor Trustee with respect to the Securities of any series shall be appointed by Act of the
	Holders of a majority in principal amount of the Outstanding Securities of such series delivered to
	the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
	acceptance of such appointment in accordance with the applicable requirements of Section 6.9,

	Securities and accepted appointment in the manner required by Section 6.9, any Holder of a Security
	who has been a bona fide Holder of a Security of such series for at least six months may, on behalf
	of himself and all others similarly situated, petition any court of competent jurisdiction for the
	appointment of a successor Trustee with respect to the Securities of such series.

	addresses appear in the Security Register and, if Securities of such series are issued as Bearer
	Securities, by publishing notice of such event once in an Authorized Newspaper in each Place of
	Payment located outside the United States. Each notice shall include the name of the successor
	Trustee with respect to the Securities of such series and the address of its Corporate Trust
	Office.
	     (7) In no event shall any retiring Trustee be liable for the acts or omissions of any
	successor Trustee hereunder.
|  |  |  | 
| Section 6.9. |  | Acceptance of Appointment by Successor. | 
 
	     (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities,
	such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and the
	retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal
	of the retiring Trustee shall become effective and such successor Trustee, without any further act,
	deed or conveyance, shall become vested with all the rights, powers, trusts and duties hereunder of
	the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring
	Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such
	successor Trustee all the rights, powers and trusts of the retiring Trustee and, subject to Section
	10.3, shall duly assign, transfer and deliver to such successor Trustee all property and money held
	by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in
	Section 6.6.
	54
 
	 
	     (2) Upon the appointment hereunder of any successor Trustee with respect to the Securities of
	one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee
	shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall
	accept such appointment and which (1) shall contain such provisions as shall be necessary or
	desirable to transfer and confirm to, and to vest in, such successor Trustee all the rights,
	powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
	series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is
	not retiring with respect to all Securities, shall contain such provisions as shall be deemed
	necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring
	Trustee with respect to the Securities of that or those series as to which the retiring Trustee is
	not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change
	any of the provisions of this Indenture as shall be necessary to provide for or facilitate the
	administration of the trusts hereunder by more than one Trustee, it being understood that nothing
	herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
	trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart
	from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall
	be responsible for any notice given to, or received by, or any act or failure to act on the part of
	any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture,
	the resignation or removal of the retiring Trustee shall become effective to the extent provided
	therein, such retiring Trustee shall have no further responsibility for the exercise of rights and
	powers or for the performance of the duties and obligations vested in the Trustee under this
	Indenture with respect to the Securities of that or those series to which the appointment of such
	successor Trustee relates other than as hereinafter expressly set forth, and such successor
	Trustee, without any further act, deed or conveyance, shall become vested with all the rights,
	powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
	series to which the appointment of such successor Trustee relates; but, on request of the Company
	or such successor Trustee, such retiring Trustee, upon payment of its charges with respect to the
	Securities of that or those series to which the appointment of such successor Trustee relates and
	subject to Section 10.3 shall duly assign, transfer and deliver to such successor Trustee, to the
	extent contemplated by such supplemental indenture, the property and money held by such retiring
	Trustee hereunder with respect to the Securities of that or those series to which the appointment
	of such successor Trustee relates, subject to its claim, if any, provided for in Section 6.6.
	     (3) Upon request of any Person appointed hereunder as a successor Trustee, the Company shall
	execute any and all instruments for more fully and certainly vesting in and confirming to such
	successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this
	Section, as the case may be.
	     (4) No Person shall accept its appointment hereunder as a successor Trustee unless at the
	time of such acceptance such successor Person shall be qualified and eligible under this Article.
|  |  |  | 
| Section 6.10. |  | Merger, Conversion, Consolidation or Succession to Business. | 
 
	     Any Corporation into which the Trustee may be merged or converted or with which it may be
	consolidated, or any Corporation resulting from any merger, conversion or consolidation
	55
 
	 
	to which the Trustee shall be a party, or any Corporation succeeding to all or substantially
	all of the corporate trust business of the Trustee, shall be the successor of the Trustee
	hereunder, without the execution or filing of any paper or any further act on the part of any of
	the parties hereto. In case any Securities shall have been authenticated but not delivered by the
	Trustee then in office, any successor by merger, conversion or consolidation to such authenticating
	Trustee may adopt such authentication and deliver the Securities so authenticated with the same
	effect as if such successor Trustee had itself authenticated such Securities.
|  |  |  | 
| Section 6.11. |  | Appointment of Authenticating Agent. | 
 
	     The Trustee may appoint one or more Authenticating Agents acceptable to the Company with
	respect to one or more series of Securities which shall be authorized to act on behalf of the
	Trustee to authenticate Securities of that or those series issued upon original issue, exchange,
	registration of transfer, partial redemption or partial repayment or pursuant to Section 3.6, and
	Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid
	and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference
	is made in this Indenture to the authentication and delivery of Securities by the Trustee or the
	Trustees certificate of authentication, such reference shall be deemed to include authentication
	and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of
	authentication executed on behalf of the Trustee by an Authenticating Agent.
	     Each Authenticating Agent must be acceptable to the Company and, except as provided in or
	pursuant to this Indenture, shall at all times be a corporation that would be permitted by the
	Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act,
	is authorized under applicable law and by its charter to act as an Authenticating Agent and has a
	combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
	Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be eligible in
	accordance with the provisions of this Section, it shall resign immediately in the manner and with
	the effect specified in this Section.
	     Any Corporation into which an Authenticating Agent may be merged or converted or with which it
	may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to
	which such Authenticating Agent shall be a party, or any Corporation succeeding to all or
	substantially all of the corporate agency or corporate trust business of an Authenticating Agent,
	shall be the successor of such Authenticating Agent hereunder,
	provided
	such Corporation shall be
	otherwise eligible to be an Authenticating Agent under this Section, without the execution or
	filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.
	     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
	and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
	giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a
	notice of resignation or upon such a termination, or in case at any time such Authenticating Agent
	shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
	appoint a successor Authenticating Agent which shall be acceptable to the Company and shall (i)
	mail written notice of such appointment by first-class
	56
 
	 
	mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with
	respect to which such Authenticating Agent shall serve, as their names and addresses appear in the
	Security Register, and (ii) if Securities of the series are issued as Bearer Securities, publish
	notice of such appointment at least once in an Authorized Newspaper in the place where such
	successor Authenticating Agent has its principal office if such office is located outside the
	United States. Any successor Authenticating Agent, upon acceptance of its appointment hereunder,
	shall become vested with all the rights, powers and duties of its predecessor hereunder, with like
	effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall
	be appointed unless eligible under the provisions of this Section.
	     The Company agrees to pay each Authenticating Agent from time to time reasonable compensation
	for its services under this Section. If the Trustee makes such payments, it shall be entitled to
	be reimbursed for such payments, subject to the provisions of Section 6.6.
	     The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each Authenticating Agent.
	     If an Authenticating Agent is appointed with respect to one or more series of Securities
	pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to
	or in lieu of the Trustees certificate of authentication, an alternate certificate of
	authentication in substantially the following form:
	    This is one of the Securities of the series designated herein referred to in
	the within-mentioned Indenture.

	     If all of the Securities of any series may not be originally issued at one time, and if the
	Trustee does not have an office capable of authenticating Securities upon original issuance located
	in a Place of Payment where the Company wishes to have Securities of such series authenticated upon
	original issuance, the Trustee, if so requested in writing by the Company (which writing need not
	be accompanied by or contained in an Officers Certificate by the Company), shall appoint in
	accordance with this Section an Authenticating Agent having an office in a Place of Payment
	designated by the Company with respect to such series of Securities.

	affected thereby, shall
	     (1) change the Stated Maturity of the principal of, or any premium or installment of interest
	on or any Additional Amounts with respect to, any Security; or reduce the principal amount thereof
	or the rate (or modify the calculation of such rate in a manner that may reduce such rate) of
	interest thereon or any Additional Amounts with respect thereto, or any premium payable upon the

	under this Indenture of the Holders of Securities of any other series.
	     It shall not be necessary for any Act of Holders of Securities under this Section to approve

	thereby.
|  |  |  | 
| Section 9.5. |  | Reference in Securities to Supplemental Indentures. | 
 
	     Securities of any series authenticated and delivered after the execution of any supplemental
	indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in

	the Company shall so determine, new Securities of any series so modified as to conform, in the
	opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and

	ARTICLE 10
	Covenants
|  |  |  | 
| Section 10.1. |  | Payment of Principal, any Premium, Interest and Additional Amounts. | 
 
	     The Company covenants and agrees for the benefit of the Holders of the Securities of each
	series that it will duly and punctually pay the principal of, any premium and interest on and any
	Additional Amounts with respect to the Securities of such series in accordance with the terms
	thereof, any Coupons appertaining thereto and this Indenture. Any interest due on any Bearer
	Security on or before the Maturity thereof, and any Additional Amounts payable with respect to such
	interest, shall be payable only upon presentation and surrender of the Coupons appertaining thereto
	for such interest as they severally mature.
|  |  |  | 
| Section 10.2. |  | Maintenance of Office or Agency. | 
 
	     The Company shall maintain in each Place of Payment for any series of Securities an Office or
	Agency where Securities of such series (but not Bearer Securities, except as otherwise provided
	below, unless such Place of Payment is located outside the United States) may be presented or
	surrendered for payment, where Securities of such series may be surrendered for registration of
	transfer or exchange, where Securities of such series that are convertible or exchangeable may be
	surrendered for conversion or exchange, and where notices and demands to
	64
 
	 
	or upon the Company in respect of the Securities of such series relating thereto and this
	Indenture may be served. If Securities of a series are issuable as Bearer Securities, the Company
	shall maintain, subject to any laws or regulations applicable thereto, an Office or Agency in a
	Place of Payment for such series which is located outside the United States where Securities of
	such series and any Coupons appertaining thereto may be presented and surrendered for payment;
	provided, however
	, that if the Securities of such series are listed on The Stock Exchange of the
	United Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock
	exchange located outside the United States and such stock exchange shall so require, the Company
	shall maintain a Paying Agent in London, Luxembourg or any other required city located outside the
	United States, as the case may be, so long as the Securities of such series are listed on such
	exchange. The Company will give prompt written notice to the Trustee of the location, and any
	change in the location, of such Office or Agency. If at any time the Company shall fail to
	maintain any such required Office or Agency or shall fail to furnish the Trustee with the address
	thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate
	Trust Office of the Trustee, except that Bearer Securities of such series and any Coupons
	appertaining thereto may be presented and surrendered for payment at the place specified for the
	purpose with respect to such Securities as provided in or pursuant to this Indenture, and the
	Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders,
	notices and demands.
	     Except as otherwise provided in or pursuant to this Indenture, no payment of principal,
	premium, interest or Additional Amounts with respect to Bearer Securities shall be made at any
	Office or Agency in the United States or by check mailed to any address in the United States or by
	transfer to an account maintained with a bank located in the United States;
	provided, however
	, if
	amounts owing with respect to any Bearer Securities shall be payable in Dollars, payment of
	principal of, any premium or interest on and any Additional Amounts with respect to any such
	Security may be made at a designated Corporate Trust Office of the Trustee or any Office or Agency
	designated by the Company in the Borough of Manhattan, The City of New York, if (but only if)
	payment of the full amount of such principal, premium, interest or Additional Amounts at all
	offices outside the United States maintained for such purpose by the Company in accordance with
	this Indenture is illegal or effectively precluded by exchange controls or other similar
	restrictions.
	     The Company may also from time to time designate one or more other Offices or Agencies where
	the Securities of one or more series may be presented or surrendered for any or all such purposes
	and may from time to time rescind such designations;
	provided, however
	, that no such designation or
	rescission shall in any manner relieve the Company of its obligation to maintain an Office or
	Agency in each Place of Payment for Securities of any series for such purposes. The Company shall
	give prompt written notice to the Trustee of any such designation or rescission and of any change
	in the location of any such other Office or Agency. Unless otherwise provided in or pursuant to
	this Indenture, the Company hereby designates as the Place of Payment for each series of Securities
	Minneapolis, Minnesota, and initially appoints the office of the Trustee at Wells Fargo Bank,
	National Association, Corporate Trust Operations, 608 Second Avenue South, N9303-121, Minneapolis,
	Minnesota 55479 as the Office or Agency for the purposes set forth in the first paragraph of this
	Section 10.2.
	65
 
	 
	     Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if and so
	long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be
	payable in a Foreign Currency, or so long as it is required under any other provision of this
	Indenture, then the Company will maintain with respect to each such series of Securities, or as so
	required, at least one exchange rate agent.
|  |  |  | 
| Section 10.3. |  | Money for Securities Payments to Be Held in Trust. | 
 
	     If the Company shall at any time act as its own Paying Agent with respect to any series of
	Securities, it shall, on or before each due date of the principal of, any premium or interest on or
	Additional Amounts with respect to any of the Securities of such series, segregate and hold in
	trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency
	unit or units or composite currency or currencies in which the Securities of such series are
	payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series)
	sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due
	until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and
	shall promptly notify the Trustee of its action or failure so to act.
	     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
	shall, on or prior to each due date of the principal of, any premium or interest on or any
	Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a
	sum (in the currency or currencies, currency unit or units or composite currency or currencies
	described in the preceding paragraph) sufficient to pay the principal or any premium, interest or
	Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons
	entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify
	the Trustee of its action or failure so to act.
	     The Company shall cause each Paying Agent for any series of Securities other than the Trustee
	to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
	Trustee, subject to the provisions of this Section, that such Paying Agent shall:
	     (1) hold all sums held by it for the payment of the principal of, any premium or interest on
	or any Additional Amounts with respect to Securities of such series in trust for the benefit of the
	Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as
	provided in or pursuant to this Indenture;
	     (2) give the Trustee notice of any default by the Company (or any other obligor upon the
	Securities of such series) in the making of any payment of principal, any premium or interest on or
	any Additional Amounts with respect to the Securities of such series; and
	     (3) at any time during the continuance of any such default, upon the written request of the
	Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.
	     The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
	this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay,
	to the Trustee all sums held in trust by the Company or such Paying Agent,
	66
 
	 
	such sums to be held by the Trustee upon the same terms as those upon which such sums were
	held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the
	Trustee, such Paying Agent shall be released from all further liability with respect to such sums.
	     Except as otherwise provided herein or pursuant hereto and subject to any applicable escheat
	and abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held
	by the Company, in trust for the payment of the principal of, any premium or interest on or any
	Additional Amounts with respect to any Security of any series or any Coupon appertaining thereto
	and remaining unclaimed for two years after such principal or any such premium or interest or any
	such Additional Amounts shall have become due and payable shall be paid to the Company on Company
	Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of
	such Security or any Coupon appertaining thereto shall thereafter, as an unsecured general
	creditor, look only to the Company for payment thereof, and all liability of the Trustee or such
	Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof,
	shall thereupon cease;
	provided, however
	, that the Trustee or such Paying Agent, before being
	required to make any such repayment, may at the expense of the Company cause to be published once,
	in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of
	Registered Securities of such series, or both, notice that such money 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 nor shall it be later than two years after such principal and any premium or
	interest or Additional Amounts shall have become due and payable, any unclaimed balance of such
	money then remaining will be repaid to the Company.
|  |  |  | 
| Section 10.4. |  | Additional Amounts. | 
 
	     If any Securities of a series provide for the payment of Additional Amounts, the Company
	agrees to pay to the Holder of any such Security or any Coupon appertaining thereto Additional
	Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this
	Indenture there is mentioned, in any context, the payment of the principal of or any premium or
	interest on, or in respect of, any Security of any series or any Coupon or the net proceeds
	received on the sale or exchange of any Security of any series, such mention shall be deemed to
	include mention of the payment of Additional Amounts provided by the terms of such series
	established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are,
	were or would be payable in respect thereof pursuant to such terms, and express mention of the
	payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as
	excluding the payment of Additional Amounts in those provisions hereof where such express mention
	is not made.
	     Except as otherwise provided in or pursuant to this Indenture or the Securities of the
	applicable series, if the Securities of a series provide for the payment of Additional Amounts, at
	least 10 days prior to the first Interest Payment Date with respect to such series of Securities
	(or if the Securities of such series shall not bear interest prior to Maturity, the first day on
	which a payment of principal is made), and at least 10 days prior to each date of payment of
	principal or interest if there has been any change with respect to the matters set forth in the
	below-mentioned Officers Certificate, the Company shall furnish to the Trustee and the principal
	Paying Agent or
	67
 
	 
	Paying Agents, if other than the Trustee, an Officers Certificate instructing the Trustee and
	such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or
	interest on the Securities of such series shall be made to Holders of Securities of such series or
	the Coupons appertaining thereto who are United States Aliens without withholding for or on account
	of any tax, assessment or other governmental charge described in the Securities of such series. If
	any such withholding shall be required, then such Officers Certificate shall specify by country
	the amount, if any, required to be withheld on such payments to such Holders of Securities or
	Coupons, and the Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts
	required by the terms of such Securities. The Company covenants to indemnify the Trustee and any
	Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably
	incurred without negligence or bad faith on their part arising out of or in connection with actions
	taken or omitted by any of them in reliance on any Officers Certificate furnished pursuant to this
	Section.
|  |  |  | 
| Section 10.5. |  | Limitation on Liens. | 
 
	     The Company agrees that it will not, and will not permit any Restricted Subsidiary to, create,
	incur, issue, assume or guarantee any indebtedness for money borrowed (Debt), secured by a
	Mortgage upon any Operating Property, or upon shares of capital stock or Debt issued by any
	Restricted Subsidiary and owned by the Company or any Restricted Subsidiary, at the date of this
	Indenture or hereafter acquired, without effectively providing concurrently that the Outstanding
	Securities hereunder (together with, if the Company shall so determine, any other Debt of the
	Company or such Restricted Subsidiary then existing or thereafter created which is not subordinate
	to the Securities) shall be secured equally and ratably with or, at the option of the Company,
	prior to such Debt so long as such Debt shall be so secured, unless, at the time of such creation,
	incurrence, issuance, assumption or guarantee, after giving effect thereto and to the retirement of
	any Debt which is concurrently being retired, the aggregate amount of all such Debt secured by
	Mortgages which would otherwise be subject to such restrictions (other than any Debt secured by
	Mortgages permitted in Clauses (1) through (7) of this Section 10.5), together with all
	Attributable Debt with respect to Sale and Leaseback Transactions (other than certain Sale and
	Leaseback Transactions that are permitted under paragraph (b) of Section 10.6 below) would not
	exceed 15% of Consolidated Net Tangible Assets;
	provided, however
	, that this Section shall not
	apply to, and there shall be excluded from Debt in any computation under this Section, Debt secured
	by:
	     (1) Mortgages on property existing at the time of the acquisition thereof;
	     (2) Mortgages on property of a Corporation or other entity existing at the time such
	Corporation or other entity is merged into or consolidated with the Company or a Restricted
	Subsidiary or at the time of a sale, lease or other disposition of the properties of such
	Corporation or other entity (or a division thereof) as an entirety or substantially as an entirety
	to the Company or a Restricted Subsidiary, provided that any such Mortgage does not extend to any
	property owned by the Company or Restricted Subsidiary immediately prior to such merger,
	consolidation, sale, lease or disposition;
	     (3) Mortgages on property of a corporation or other entity existing at the time such
	corporation becomes a Restricted Subsidiary;
	68
 
	 
	     (4) Mortgages in favor of the Company or a Restricted Subsidiary;
	     (5) Mortgages to secure all or part of the cost of acquisition, construction, development or
	improvement of the underlying property, or to secure Debt incurred to provide funds for any such
	purpose, provided that the commitment of the creditor to extend the credit secured by any such
	Mortgage shall have been obtained not later than 365 days after the later of (A) the completion of
	the acquisition, construction, development or improvement of such property or (B) the placing in
	operation of such property;
	     (6) Mortgages in favor of the United States of America or any State thereof, or any
	department, agency or instrumentality or political subdivision thereof, to secure partial,
	progress, advance or other payments; and
	     (7) Mortgages existing on the date of this Indenture or any extension, renewal, replacement or
	refunding of any Debt secured by a Mortgage existing on the date of this Indenture or referred to
	in clauses (1) to (3) or (5) of this Section 10.5, provided that the principal amount of Debt
	secured thereby and not otherwise authorized by clauses (1) to (3) or (5) shall not exceed the
	principal amount of Debt, plus any premium or fee payable in connection with any such extension,
	renewal, replacement or refunding, so secured at the time of such extension, renewal, replacement
	or refunding.
|  |  |  | 
| Section 10.6. |  | Limitation on Sale and Leaseback | 
 
	     (a) The Company agrees that it will not, and will not permit any Restricted Subsidiary to
	enter into any arrangement with any person providing for the leasing by the Company or any
	Restricted Subsidiary of any Operating Property that has been or is to be sold or transferred by
	the Company or such Restricted Subsidiary to such person with the intention of taking back a lease
	of such property (a Sale and Leaseback Transaction), unless the terms of such sale or transfer
	have been determined by the Board of Directors to be fair and arms-length and either:
|  | (i) |  | within 180 days after the receipt of the proceeds of the sale or transfer, the
	Company or any Restricted Subsidiary applies an amount equal to the greater of the net
	proceeds of the sale or transfer or the fair value of such Operating Property at the
	time of such sale or transfer to the prepayment or retirement (other than any mandatory
	prepayment or retirement) of Senior Funded Debt; or | 
 
|  | (ii) |  | the Company or such Restricted Subsidiary would be entitled, at the effective
	date of the sale or transfer, to incur Debt secured by a Mortgage on such Operating
	Property, in an amount at least equal to the Attributable Debt in respect of the Sale
	and Leaseback Transaction, without equally and ratably securing the Securities pursuant
	to Section 10.5. | 
 
	     (b) The foregoing restriction in paragraph (a) above will not apply to any Sale and Leaseback
	Transaction (i) for a term of not more than three years including renewals or (ii)
	69
 
	 
	between the Company and a Restricted Subsidiary or between Restricted Subsidiaries, provided
	that the lessor shall be the Company or a wholly-owned Restricted Subsidiary.
|  |  |  | 
| Section 10.7. |  | Corporate Existence. | 
 
	     Subject to Article Eight, the Company shall do or cause to be done all things necessary to
	preserve and keep in full force and effect its corporate existence and that of each Subsidiary and
	their respective rights (charter and statutory) and franchises;
	provided, however
	, that the
	foregoing shall not obligate the Company or any Subsidiary to preserve any such right or franchise
	if the Company or any Subsidiary shall determine that the preservation thereof is no longer
	desirable in the conduct of its business or the business of such Subsidiary and that the loss
	thereof is not disadvantageous in any material respect to any Holder.
|  |  |  | 
| Section 10.8. |  | Waiver of Certain Covenants. | 
 
	     The Company may omit in any particular instance to comply with any term, provision or
	condition set forth in Sections 10.5 or 10.6 with respect to the Securities of any series if before
	the time for such compliance the Holders of at least a majority in principal amount of the
	Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance
	in such instance or generally shall have waived compliance with such term, provision or condition,
	but no such waiver shall extend to or affect such term, provision or condition except to the extent
	so expressly waived, and, until such waiver shall become effective, the obligations of the Company
	and the duties of the Trustee in respect of any such term, provision or condition shall remain in
	full force and effect.

	     (1) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal
	year, a written statement (which need not be contained in or accompanied by an Officers
	Certificate) signed by the principal executive officer, the principal financial officer or the
	principal accounting officer of the Company, stating that
	     (a) a review of the activities of the Company during such year and of its performance
	under this Indenture has been made under his or her supervision, and
	     (b) to the best of his or her knowledge, based on such review, (a) the Company has
	complied with all the conditions and covenants imposed on it under this Indenture throughout
	such year, or, if there has been a default in the fulfillment of any such condition or
	covenant, specifying each such default known to him or her and the nature and status
	thereof, and (b) no event has occurred and is continuing which is, or after notice or lapse
	of time or both would become, an Event of Default, or, if such an event has occurred and is
	continuing, specifying each such event known to him and the nature and status thereof.
	     (2) The Company shall deliver to the Trustee, within five Business Days after becoming aware
	of the occurrence thereof, written notice of any Event of Default or any event which after
	70
 
	 
	notice or lapse of time or both would become an Event of Default pursuant to clause (4) of
	Section 5.1.
	     (3) The Trustee shall have no duty to monitor the Companys compliance with the covenants
	contained in this Article 10 other than as specifically set forth in this Section 10.9.

	prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to
	the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities
	of such series to be redeemed.
|  |  |  | 
| Section 11.3. |  | Selection by Trustee of Securities to be Redeemed. | 
 
	     If less than all of the Securities of any series with the same issue date, interest rate or
	formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be
	redeemed shall be selected not more than 60 days and not less than 30 days prior to the Redemption
	Date by the Trustee from the Outstanding Securities of such series not previously called for
	redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for
	the selection for redemption of portions of the principal amount of Registered Securities of such
	series;
	provided, however
	, that no such partial redemption shall reduce the portion of the
	principal amount of a Registered Security of such series not redeemed to less than the minimum
	denomination for a Security of such series established herein or pursuant hereto.
	     The Trustee shall promptly notify the Company and the Security Registrar (if other than
	itself) in writing of the Securities selected for redemption and, in the case of any Securities
	selected for partial redemption, the principal amount thereof to be redeemed.
	     For all purposes of this Indenture, unless the context otherwise requires, all provisions
	relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to
	be redeemed only in part, to the portion of the principal of such Securities which has been or is
	to be redeemed.
	71
 
	 
	     Unless otherwise specified in or pursuant to this Indenture or the Securities of any series,
	if any Security selected for partial redemption is converted into Common Stock or exchanged for
	other securities in part before termination of the conversion or exchange right with respect to the
	portion of the Security so selected, the converted portion of such Security shall be deemed (so far
	as may be) to be the portion selected for redemption. Securities which have been converted or
	exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as
	Outstanding for the purpose of such selection.
|  |  |  | 
| Section 11.4. |  | Notice of Redemption. | 
 
	     Notice of redemption shall be given in the manner provided in Section 1.6, not less than 30
	nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the
	Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by
	mailing in the manner herein provided to the Holder of any Registered Securities designated for
	redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect
	the validity of the proceedings for the redemption of any other Securities or portion thereof.
	     Any notice that is mailed to the Holder of any Registered Securities in the manner herein
	provided shall be conclusively presumed to have been duly given, whether or not such Holder
	receives the notice.
	     All notices of redemption shall state:
	     (1) the Redemption Date,
	     (2) the Redemption Price,
	     (3) if less than all Outstanding Securities of any series are to be redeemed, the
	identification (and, in the case of partial redemption, the principal amount) of the particular
	Security or Securities to be redeemed,
	     (4) in case any Security is to be redeemed in part only, the notice which relates to such
	Security shall state that on and after the Redemption Date, upon surrender of such Security, the
	Holder of such Security will receive, without charge, a new Security or Securities of authorized
	denominations for the principal amount thereof remaining unredeemed,
	     (5) that, on the Redemption Date, the Redemption Price shall become due and payable upon each
	such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall
	cease to accrue on and after said date,
	     (6) the place or places where such Securities, together (in the case of Bearer Securities)
	with all Coupons appertaining thereto, if any, maturing after the Redemption Date, are to be
	surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts
	pertaining thereto,
	     (7) that the redemption is for a sinking fund, if such is the case,
	72
 
	 
	     (8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any,
	surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed
	for redemption or the amount of any such missing Coupon or Coupons will be deducted from the
	Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any
	Paying Agent is furnished,
	     (9) if Bearer Securities of any series are to be redeemed and no Registered Securities of
	such series are to be redeemed, and if such Bearer Securities may be exchanged for Registered
	Securities not subject to redemption on the Redemption Date pursuant to Section 3.5 or otherwise,
	the last date, as determined by the Company, on which such exchanges may be made,
	     (10) in the case of Securities of any series that are convertible into Common Stock or
	exchangeable for other securities, the conversion or exchange price or rate, the date or dates on
	which the right to convert or exchange the principal of the Securities of such series to be
	redeemed will commence or terminate and the place or places where such Securities may be
	surrendered for conversion or exchange, and
	     (11) the CUSIP number and/or similar numbers of such Securities, if any (or any other numbers
	used by a Depositary to identify such Securities).
	     A notice of redemption published as contemplated by Section 1.6 need not identify particular
	Registered Securities to be redeemed.
	     Notice of redemption of Securities to be redeemed at the election of the Company shall be
	given by the Company or, at the Companys request, by the Trustee in the name and at the expense of
	the Company.
|  |  |  | 
| Section 11.5. |  | Deposit of Redemption Price. | 
 
	     On or prior to any Redemption Date, the Company shall deposit, with respect to the Securities
	of any series called for redemption pursuant to Section 11.4, with the Trustee or with a Paying
	Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as
	provided in Section 10.3) an amount of money in the applicable Currency sufficient to pay the
	Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless
	otherwise specified pursuant to Section 3.1 or in the Securities of such series) any accrued
	interest on and Additional Amounts with respect thereto, all such Securities or portions thereof
	which are to be redeemed on that date.
|  |  |  | 
| Section 11.6. |  | Securities Payable on Redemption Date. | 
 
	     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
	on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
	and after such date (unless the Company shall default in the payment of the Redemption Price and
	accrued interest) such Securities shall cease to bear interest and the Coupons for such interest
	appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall
	be void. Upon surrender of any such Security for redemption in accordance with said notice,
	together with all Coupons, if any, appertaining thereto maturing
	73
 
	 
	after the Redemption Date, such Security shall be paid by the Company at the Redemption Price,
	together with any accrued interest and Additional Amounts to the Redemption Date;
	provided,
	however
	, that, except as otherwise provided in or pursuant to this Indenture or the Bearer
	Securities of such series, installments of interest on Bearer Securities whose Stated Maturity is
	on or prior to the Redemption Date shall be payable only upon presentation and surrender of Coupons
	for such interest (at an Office or Agency located outside the United States except as otherwise
	provided in Section 10.2), and
	provided, further
	, that, except as otherwise specified in or
	pursuant to this Indenture or the Registered Securities of such series, installments of interest on
	Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable
	to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the
	close of business on the Regular Record Dates therefor according to their terms and the provisions
	of Section 3.7.
	     If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant
	Coupons maturing after the Redemption Date, such Security may be paid after deducting from the
	Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender
	of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be
	furnished to them such security or indemnity as they may require to save each of them and any
	Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or
	any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from
	the Redemption Price, such Holder shall be entitled to receive the amount so deducted;
	provided,
	however
	, that any interest or Additional Amounts represented by Coupons shall be payable only upon
	presentation and surrender of those Coupons at an Office or Agency for such Security located
	outside of the United States except as otherwise provided in Section 10.2.
	     If any Security called for redemption shall not be so paid upon surrender thereof for
	redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date
	at the rate prescribed therefor in the Security.
|  |  |  | 
| Section 11.7. |  | Securities Redeemed in Part. | 
 
	     Any Registered Security which is to be redeemed only in part shall be surrendered at any
	Office or Agency for such Security (with, if the Company or the Trustee so requires, due
	endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
	Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the
	Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security
	without service charge, a new Registered Security or Securities of the same series, containing
	identical terms and provisions, of any authorized denomination as requested by such Holder in
	aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of
	the Security so surrendered. If a Security in global form is so surrendered, the Company shall
	execute, and the Trustee shall authenticate and deliver to the U.S. Depositary or other Depositary
	for such Security in global form as shall be specified in the Company Order with respect thereto to
	the Trustee, without service charge, a new Security in global form in a denomination equal to and
	in exchange for the unredeemed portion of the principal of the Security in global form so
	surrendered.

	ARTICLE 12
	Sinking Funds
|  |  |  | 
| Section 12.1. |  | Applicability of Article. | 
 
	     The provisions of this Article shall be applicable to any sinking fund for the retirement of
	Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture
	or any Security of such series issued pursuant to this Indenture.
	     The minimum amount of any sinking fund payment provided for by the terms of Securities of any
	series is herein referred to as a mandatory sinking fund payment, and any payment in excess of
	such minimum amount provided for by the terms of Securities of such series is herein referred to as
	an optional sinking fund payment. If provided for by the terms of Securities of any series, the
	cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2.
	Each sinking fund payment shall be applied to the redemption of Securities of any series as
	provided for by the terms of Securities of such series and this Indenture.
|  |  |  | 
| Section 12.2. |  | Satisfaction of Sinking Fund Payments with Securities. | 
 
	     The Company may, in satisfaction of all or any part of any sinking fund payment with respect
	to the Securities of any series to be made pursuant to the terms of such Securities, accompanied by
	a written notice to the Trustee, (1) deliver Outstanding Securities of such series (other than any
	of such Securities previously called for redemption or any of such Securities in respect of which
	cash shall have been released to the Company), together in the case of any Bearer Securities of
	such series with all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities
	of such series which have been redeemed either at the election of the Company pursuant to the terms
	of such series of Securities or through the application of permitted optional sinking fund payments
	pursuant to the terms of such Securities,
	provided
	that such series of Securities have not been
	previously so credited. Such Securities shall be received and credited for such purpose by the
	Trustee at the Redemption Price specified in such Securities for redemption through operation of
	the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If, as
	a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to
	this Section 12.2, the principal amount of Securities of such series to be redeemed in order to
	satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call
	Securities of such series for redemption, except upon Company Request, and such cash payment shall
	be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment,
	provided, however
	, that the Trustee or such Paying Agent shall at the request of the Company from
	time to time pay over and deliver to the Company any cash payment so being held by the Trustee or
	such Paying Agent upon delivery by the Company to the Trustee of Securities of that series
	purchased by the Company having an unpaid principal amount equal to the cash payment requested to
	be released to the Company.
	75
 
	 
|  |  |  | 
| Section 12.3. |  | Redemption of Securities for Sinking Fund. | 
 
	     Not less than 75 days prior to each sinking fund payment date for any series of Securities,
	the Company shall deliver to the Trustee an Officers Certificate specifying the amount of the next
	ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the
	portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if
	any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to
	Section 12.2, and the optional amount, if any, to be added in cash to the next ensuing mandatory
	sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not
	theretofore delivered. If such Officers Certificate shall specify an optional amount to be added
	in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be
	obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund
	payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment
	date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given
	in the name of and at the expense of the Company in the manner provided in Section 11.4. Such
	notice having been duly given, the redemption of such Securities shall be made upon the terms and
	in the manner stated in Sections 11.6 and 11.7.
	ARTICLE 13
	Repayment at the Option of Holders
|  |  |  | 
| Section 13.1. |  | Applicability of Article. | 
 
	     Securities of any series which are repayable at the option of the Holders thereof before their
	Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The
	repayment of any principal amount of Securities pursuant to such option of the Holder to require
	repayment of Securities before their Stated Maturity, for purposes of Section 3.9, shall not
	operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities
	unless and until the Company, at its option, shall deliver or surrender the same to the Trustee
	with a directive that such Securities be cancelled. Notwithstanding anything to the contrary
	contained in this Section 13.1, in connection with any repayment of Securities, the Company may
	arrange for the purchase of any Securities by an agreement with one or more investment bankers or
	other purchasers to purchase such Securities by paying to the Holders of such Securities on or
	before the close of business on the repayment date an amount not less than the repayment price
	payable by the Company on repayment of such Securities, and the obligation of the Company to pay
	the repayment price of such Securities shall be satisfied and discharged to the extent such payment
	is so paid by such purchasers.
	76
 
	 
	ARTICLE 14
	Securities in Foreign Currencies
|  |  |  | 
| Section 14.1. |  | Applicability of Article. | 
 
	     Whenever this Indenture provides for (i) any action by, or the determination of any of the
	rights of, Holders of Securities of any series in which not all of such Securities are denominated
	in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any
	provision to the contrary in the form of Security of any particular series or pursuant to this
	Indenture or the Securities, any amount in respect of any Security denominated in a Currency other
	than Dollars shall be treated for any such action or distribution as that amount of Dollars that
	could be obtained for such amount on such reasonable basis of exchange and as of the record date
	with respect to Registered Securities of such series (if any) for such action, determination of
	rights or distribution (or, if there shall be no applicable record date, such other date reasonably
	proximate to the date of such action, determination of rights or distribution) as the Company may
	specify in a written notice to the Trustee.
	ARTICLE 15
	Meetings of Holders of Securities
|  |  |  | 
| Section 15.1. |  | Purposes for Which Meetings May Be Called. | 
 
	     A meeting of Holders of Securities of any series may be called at any time and from time to
	time pursuant to this Article to make, give or take any request, demand, authorization, direction,
	notice, consent, waiver or other Act provided by this Indenture to be made, given or taken by
	Holders of Securities of such series.
|  |  |  | 
| Section 15.2. |  | Call, Notice and Place of Meetings. | 
 
	     (1) The Trustee may at any time call a meeting of Holders of Securities of any series for any
	purpose specified in Section 15.1, to be held at such time and at such place in the Borough of
	Manhattan, The City of New York, or, if Securities of such series have been issued in whole or in
	part as Bearer Securities, in London or in such place outside the United States as the Trustee
	shall determine. Notice of every meeting of Holders of Securities of any series, setting forth the
	time and the place of such meeting and in general terms the action proposed to be taken at such
	meeting, shall be given, in the manner provided in Section 1.6, not less than 21 nor more than 180
	days prior to the date fixed for the meeting.
	     (2) In case at any time the Company (by or pursuant to a Board Resolution) or the Holders of
	at least 10% in principal amount of the Outstanding Securities of any series shall have requested
	the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified
	in Section 15.1, by written request setting forth in reasonable detail the action proposed to be
	taken at the meeting, and the Trustee shall not have mailed notice of or made the first publication
	of the notice of such meeting within 21 days after receipt of such request (whichever
	77
 
	 
	shall be required pursuant to Section 1.6) or shall not thereafter proceed to cause the
	meeting to be held as provided herein, then the Company or the Holders of Securities of such series
	in the amount above specified, as the case may be, may determine the time and the place in the
	Borough of Manhattan, The City of New York, or, if Securities of such series are to be issued as
	Bearer Securities, in London for such meeting and may call such meeting for such purposes by giving
	notice thereof as provided in clause (1) of this Section.
|  |  |  | 
| Section 15.3. |  | Persons Entitled to Vote at Meetings. | 
 
	     To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall
	be (1) a Holder of one or more Outstanding Securities of such series, or (2) a Person appointed by
	an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities of
	such series by such Holder or Holders. The only Persons who shall be entitled to be present or to
	speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote
	at such meeting and their counsel, any representatives of the Trustee and its counsel and any
	representatives of the Company and its counsel.
|  |  |  | 
| Section 15.4. |  | Quorum; Action. | 
 
	     The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a
	series shall constitute a quorum for any meeting of Holders of Securities of such series. In the
	absence of a quorum within 30 minutes after the time appointed for any such meeting, the meeting
	shall, if convened at the request of Holders of Securities of such series, be dissolved. In any
	other case the meeting may be adjourned for a period of not less than 10 days as determined by the
	chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at
	any reconvened meeting, such reconvened meeting may be further adjourned for a period of not less
	than 10 days as determined by the chairman of the meeting prior to the adjournment of such
	reconvened meeting. Notice of the reconvening of any adjourned meeting shall be given as provided
	in Section 15.2(1), except that such notice need be given only once not less than five days prior
	to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an
	adjourned meeting shall state expressly the percentage, as provided above, of the principal amount
	of the Outstanding Securities of such series which shall constitute a quorum.
	     Except as limited by the proviso to Section 9.2, any resolution presented to a meeting or
	adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by
	the affirmative vote of the Holders of a majority in principal amount of the Outstanding Securities
	of that series;
	provided, however
	, that, except as limited by the proviso to Section 9.2, any
	resolution with respect to any request, demand, authorization, direction, notice, consent, waiver
	or other Act which this Indenture expressly provides may be made, given or taken by the Holders of
	a specified percentage, which is less than a majority, in principal amount of the Outstanding
	Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and at
	which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified
	percentage in principal amount of the Outstanding Securities of such series.
	78
 
	 
	     Any resolution passed or decision taken at any meeting of Holders of Securities of any series
	duly held in accordance with this Section shall be binding on all the Holders of Securities of such
	series and the Coupons appertaining thereto, whether or not such Holders were present or
	represented at the meeting.
|  |  |  | 
| Section 15.5. |  | Determination of Voting Rights; Conduct and Adjournment of Meetings. | 
 
	     (1) Notwithstanding any other provisions of this Indenture, the Trustee may make such
	reasonable regulations as it may deem advisable for any meeting of Holders of Securities of such
	series in regard to proof of the holding of Securities of such series and of the appointment of
	proxies and in regard to the appointment and duties of inspectors of votes, the submission and
	examination of proxies, certificates and other evidence of the right to vote, and such other
	matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise
	permitted or required by any such regulations, the holding of Securities shall be proved in the
	manner specified in Section 1.4 and the appointment of any proxy shall be proved in the manner
	specified in Section 1.4 or by having the signature of the person executing the proxy witnessed or
	guaranteed by any trust company, bank or banker authorized by Section 1.4 to certify to the holding
	of Bearer Securities. Such regulations may provide that written instruments appointing proxies,
	regular on their face, may be presumed valid and genuine without the proof specified in Section 1.4
	or other proof.
	     (2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
	meeting, unless the meeting shall have been called by the Company or by Holders of Securities as
	provided in Section 15.2(2), in which case the Company or the Holders of Securities of the series
	calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A
	permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons
	entitled to vote a majority in principal amount of the Outstanding Securities of such series
	represented at the meeting.
	     (3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to
	one vote for each $1,000 principal amount of Securities of such series held or represented by him;
	provided, however
	, that no vote shall be cast or counted at any meeting in respect of any Security
	challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
	chairman of the meeting shall have no right to vote, except as a Holder of a Security of such
	series or proxy.
	     (4) Any meeting of Holders of Securities of any series duly called pursuant to Section 15.2
	at which a quorum is present may be adjourned from time to time by Persons entitled to vote a
	majority in principal amount of the Outstanding Securities of such series represented at the
	meeting; and the meeting may be held as so adjourned without further notice.
|  |  |  | 
| Section 15.6. |  | Counting Votes and Recording Action of Meetings. | 
 
	     The vote upon any resolution submitted to any meeting of Holders of Securities of any series
	shall be by written ballots on which shall be subscribed the signatures of the Holders of
	Securities of such series or of their representatives by proxy and the principal amounts and serial
	79
 
	 
	numbers of the Outstanding Securities of such series held or represented by them. The
	permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes
	cast at the meeting for or against any resolution and who shall make and file with the secretary of
	the meeting their verified written reports in triplicate of all votes cast at the meeting. A
	record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any
	series shall be prepared by the secretary of the meeting and there shall be attached to said record
	the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits
	by one or more persons having knowledge of the facts setting forth a copy of the notice of the
	meeting and showing that said notice was given as provided in Section 15.2 and, if applicable,
	Section 15.4. Each copy shall be signed and verified by the affidavits of the permanent chairman
	and secretary of the meeting and one such copy shall be delivered to the Company, and another to
	the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted
	at the meeting. Any record so signed and verified shall be conclusive evidence of the matters
	therein stated.
