THE SECURITIES
SECTION 2.01    Title of the Securities.  There shall be a Series of Securities designated the 4.875% Senior Notes due 2027 (the “Securities”).
SECTION 2.02    Limitation on Aggregate Principal Amount.  The Securities will be initially issued in an aggregate principal amount of $500,000,000; provided that the Company may from time to time, without giving notice to or seeking the consent of the Holders of the Securities, issue securities having the same terms (other than the issue price, interest accrual date and, in some cases, the first interest payment date) and any additional securities (the “Additional Securities”) having such similar terms, together with the applicable Securities, will constitute a single Series of Securities under the Indenture; provided, however, that no Additional Securities shall be issued that are not fungible for U.S. Federal income tax purposes with any other securities issued under the Indenture.
SECTION 2.03    Form and Dating.  The Securities will be offered and sold by the Company pursuant to the Purchase Agreement.  The Securities will be initially resold only to (i) QIBs in reliance on Rule 144A under the Securities Act (“Rule 144A”) and (ii) Persons other than U.S. Persons (as defined in Regulation S) in reliance on Regulation S under the Securities Act (“Regulation S”).  Securities initially resold pursuant to Rule 144A shall be issued initially in the form of one or more permanent global Securities in definitive, fully registered form (collectively, the “Rule 144A Global Security”) and Securities initially resold pursuant to Regulation S shall be issued initially in the form of one or more permanent global Securities in definitive, fully registered form (collectively, the “Regulation S Global Security”), in each case without interest coupons and with the global securities legend and the applicable restricted securities legend set forth in Exhibit A hereto, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Securities Custodian and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as provided in the Indenture.  Except as set forth in this Section 2.03, beneficial ownership interests in the Regulation S Global Security will not be exchangeable for interests in the Rule 144A Global Security or any other Security prior to the expiration of the Distribution Compliance Period.


6





Beneficial interests in Regulation S Global Securities may be exchanged for interests in Rule 144A Global Securities prior to the expiration of the Distribution Compliance Period if (1) such exchange occurs in connection with a transfer of Securities in compliance with Rule 144A and (2) the transferor of the beneficial interest in the Regulation S Global Security first delivers to the Trustee a written certificate (in a form satisfactory to the Trustee) to the effect that the beneficial interest in the Regulation S Global Security is being transferred to a Person (a) who the transferor reasonably believes to be a QIB, (b) purchasing for its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A and (c) in accordance with all applicable securities laws of the States of the United States and other jurisdictions.
Beneficial interests in a Rule 144A Global Security may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Security, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form set forth on the reverse side of the Security) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable).
The Rule 144A Global Security and the Regulation S Global Security are collectively referred to herein as “Global Securities”.  The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as hereinafter provided.
SECTION 2.04    Book-Entry Provisions.  This Section 2.04 shall apply only to a Global Security deposited with or on behalf of the Depositary.
The Company shall execute and the Trustee shall, in accordance with this Section 2.04, authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary and (b) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions or held by the Trustee as Securities Custodian.
Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Supplemental Indenture with respect to any Global Security held on their behalf by the Depositary or by the Trustee as Securities Custodian or under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Security for all purposes whatsoever.  Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

(ii)    written instructions directing the Trustee to make, or to direct the Securities Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause (b)(i)(A)) or Regulation S Global Security (in the case of a transfer pursuant to clause (b)(i)(B)) to reflect an increase in the aggregate principal amount of the Securities represented by the Rule 144A Global Security or Regulation S Global Security, as applicable, such instructions to contain information regarding the Depositary account to be credited with such increase,
then the Trustee shall cancel such Definitive Security and cause, or direct the Securities Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Securities Custodian, the aggregate principal amount of Securities represented by the Rule 144A Global Security or Regulation S Global Security, as applicable, to be increased by the aggregate principal amount of the Definitive Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security or Regulation S Global Security, as applicable, equal to the principal amount of the Definitive Security so canceled.  If no Rule 144A Global Securities or Regulation S Global Securities, as applicable, are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s Certificate of the Company, a new Rule 144A Global Security or Regulation S Global Security, as applicable, in the appropriate principal amount.

(ii)    If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred.
(iii)    Notwithstanding any other provisions of this Supplemental Indenture (other than the provisions set forth in Section 2.07), a Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

ARTICLE THREE
SECTION 3.01    Guaranties.  Each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, on a senior unsecured basis to each Securityholder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Supplemental Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Supplemental Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).  Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and that such 


15





Subsidiary Guarantor will remain bound under this Article Three notwithstanding any extension or renewal of any Guaranteed Obligation.
Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment.  Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations.  The obligations of each Subsidiary Guarantor hereunder shall not be affected by (1) the failure of any Securityholder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Subsidiary Guarantor) under this Supplemental Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Supplemental Indenture, the Securities or any other agreement; (4) the release of any security held by any Securityholder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Securityholder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 3.06, any change in the ownership of such Subsidiary Guarantor.
Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Securityholder or the Trustee to any security held for payment of the Guaranteed Obligations.
Except as expressly set forth in Sections 3.02 and 3.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.  Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Securityholder or the Trustee to assert any claim or demand or to enforce any remedy under this Supplemental Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.
Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or 


16





must otherwise be restored by any Securityholder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.
In furtherance of the foregoing and not in limitation of any other right which any Securityholder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Securityholders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Securityholders and the Trustee.
Each Subsidiary Guarantor agrees that, as between it, on the one hand, and the Securityholders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Section 5.1 of the Indenture for the purposes of such Subsidiary Guarantor’s Subsidiary Guaranty herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Section 5.1 of the Indenture, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section.
Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Securityholder in enforcing any rights under this Section 3.01.
SECTION 3.02    Limitation on Liability.  Any term or provision of this Supplemental Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of its Guaranteed Obligations, can be hereby guaranteed without rendering this Supplemental Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.
SECTION 3.03    Successors and Assigns.  Except as provided in Section 3.06 hereof, this Article Three shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the respective successors and assigns of the Trustee and the Securityholders and, in the event of any transfer or assignment of rights by any Securityholder or the Trustee, the rights and privileges conferred upon that party in this Supplemental Indenture and in the Securities shall 


17





automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Supplemental Indenture.
SECTION 3.04    No Waiver.  Neither a failure nor a delay on the part of either the Trustee or the Securityholders in exercising any right, power or privilege under this Article Three shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege.  The rights, remedies and benefits of the Trustee and the Securityholders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article Three at law, in equity, by statute or otherwise.
SECTION 3.05    Modification.  No modification, amendment or waiver of any provision of this Article Three, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.  No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.
SECTION 3.06    Release of Subsidiary Guarantor.  A Subsidiary Guarantor will be released from its obligations under this Section 3.06 (other than any obligation that may have arisen under Section 3.07) (a) upon the sale or disposition of such Subsidiary Guarantor (whether by merger, consolidation, the sale of its capital stock or the sale of all or substantially all of its assets (other than by lease)) and whether or not such Subsidiary Guarantor is the surviving entity in such transaction to a Person that is not the Company or a Restricted Subsidiary; provided that all of the obligations of such Subsidiary Guarantor, if any, under the USG Credit Agreement (or any successor facility) and related documentation terminate upon consummation of such transaction or (b) following the defeasance of the Securities in accordance with Section 10.1(b) of the Indenture to the extent that the obligations of the Company have been discharged thereby.
At the written request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release.
SECTION 3.07    Contribution.  Each Subsidiary Guarantor that makes a payment under its Subsidiary Guaranty shall be entitled, upon payment in full of all Guaranteed Obligations under this Supplemental Indenture, to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with generally accepted accounting principles of the United States of America.
SECTION 3.08    Merger or Consolidation of Subsidiary Guarantors.  (a) Subject to Sections 3.06 and 3.08(b) hereof, no Subsidiary Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person unless: (i) the Person formed by or surviving any such consolidation or 


18





merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under this Supplemental Indenture, in form reasonably satisfactory to the Trustee and (ii) immediately after such transaction, no Default or Event of Default exists.
(b)    The restrictions in Section 3.08(a) hereof shall not prohibit a consolidation or merger between Subsidiary Guarantors or between the Company and a Subsidiary Guarantor.
SECTION 3.09    Future Guarantors.  The Company shall cause (i) each Domestic Subsidiary that becomes one of the Company’s “significant subsidiaries” (as such term is defined in Regulation S-X under the Securities Act) after the issue date of the Securities, to become a Subsidiary Guarantor promptly following the time that it is determined to be a “significant subsidiary” in accordance with the periodic and current reporting requirements under the Securities Exchange Act of 1934, as amended, as well as Regulation S-X under the Securities Act (it being understood that the determination as to whether any Subsidiary is a “significant subsidiary” will be made at least annually in connection with the preparation of the Company’s annual financial statements) and (ii) each Domestic Subsidiary that incurs or guarantees any Capital Markets Indebtedness to become a Subsidiary Guarantor promptly following such incurrence or guarantee, as the case may be, in the case of each of (i) and (ii), by executing and delivering to the Trustee a Guaranty Agreement.

[FORM OF REVERSE SIDE OF SECURITY]
4.875% Senior Note due 2027
Section 1.Indenture
The Company issued the Securities under an Indenture, dated as of November 1, 2006, between the Company and the Trustee, and Supplemental Indenture No. 7 thereto, dated as of May 15, 2017 (collectively, the “Indenture”).  The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act as in effect on the date of the Indenture.  Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture.  The Securities are subject to all terms and provisions of the Indenture, and Securityholders are referred to the Indenture and the Trust Indenture Act for a statement of such terms and provisions.
The Securities are senior unsecured obligations of the Company initially limited to $500,000,000 aggregate principal amount at any one time outstanding.
Section 2.    Redemption
Except as set forth below and subject to compliance with Article Twelve of the Indenture, the Company shall not be entitled to redeem the Securities at its option.
The Company may redeem the Securities at its option, in whole or in part, at any time and from time to time on or after June 1, 2022, at the following redemption prices (expressed in percentages of principal amount on the redemption date), plus any accrued and unpaid interest to the redemption date (subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on June 1 of the years set forth below:
	
			
	Period
	 
	Redemption Price

	 
	 

	2022
	102.438%

	2023
	101.625%

	2024
	100.813%

	2025 and thereafter   
	100.000%






The Company may redeem the Securities at its option, in whole or in part, at any time and from time to time prior to June 1, 2022, at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and any accrued and unpaid interest to, the redemption date (subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date).


A-8







Notwithstanding the foregoing, installments of interest on Securities that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the Holders as of the close of business on the relevant record date.  The redemption price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.
“Applicable Premium” means, with respect to any Security on any redemption date, the greater of:
(1)    1.0% of the principal amount of such Security; and
(2)    the excess, if any, of (a) the present value at such redemption date of (i) the redemption price of such Security at June 1, 2022 (such redemption price being described in Section 2.08(b)), plus (ii) all required interest payments due on such Security through June 1, 2022 (excluding accrued and unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over (b) the principal amount of such Security.
“Treasury Rate” means, as of any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the heading “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after June 1, 2022, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.  The Treasury Rate will be calculated on the third Business Day preceding the redemption date.
“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities from the redemption date to June 1, 2022, that would be utilized at the time of selection in accordance with customary financial practice in pricing new issues of corporate debt securities of a maturity most nearly equal to June 1, 2022.
“Comparable Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations or (2) if the Independent Investment Banker is 


A-9







unable to obtain five such Reference Treasury Dealer Quotations, the average of all such quotations obtained by the Independent Investment Banker.
“Independent Investment Banker” means any of Wells Fargo Securities, LLC, Citigroup Global Capital Markets Inc. or Merrill Lynch, Pierce, Fenner & Smith Incorporated, and their respective successors, or, if all of the foregoing firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after approval by the Company.
“Reference Treasury Dealer” means (1) each of Wells Fargo Securities, LLC, Citigroup Global Capital Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, or their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute another Primary Treasury Dealer and (2) any one other Primary Treasury Dealer selected by the Independent Investment Banker after consultation with the Company.
“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.
Section 3.    Repurchase Upon Change of Control
If a Change of Control occurs, unless the Company has exercised its right to redeem the Securities as provided in Section 2 above, the Company shall make an offer to each Securityholder to repurchase all or any part (in integral multiples of $1,000) of that Securityholder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of Securities repurchased plus any accrued and unpaid interest on the Securities repurchased to the date of purchase.  Within 30 days following any Change of Control or, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change of Control, the Company shall mail a notice to each Securityholder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control and offering to repurchase Securities on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed.  The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control occurring on or prior to the payment date specified in the notice.
The Company shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 (the “Exchange Act”), and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in 


A-10







connection with the repurchase of the notes as a result of a Change of Control.  To the extent that the provisions of any securities laws or regulations conflict with this Section 3, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3, or the Indenture by virtue of such conflict.
The Company shall, to the extent lawful:
		
	•
	on the Change of Control payment date, accept for payment all Securities or portions of Securities properly tendered pursuant to the aforementioned offer;


		
	•
	at any time on or prior to the Change of Control payment date, deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Securities or portions of Securities properly tendered; and


		
	•
	on the Change of Control payment date or the Business Day immediately following such date, deliver or cause to be delivered to the Trustee the Securities properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Securities being purchased by the Company.


The Paying Agent will promptly mail to each Securityholder of Securities properly tendered the purchase price for the Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Securityholder a new Security equal in principal amount to any unpurchased portion of any Securities surrendered; provided, that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 above that amount.
The Company shall not be required to make an offer to repurchase the Securities upon a Change of Control if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer.
“Change of Control” means the occurrence of any of the following:
(1)    the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s properties or assets and those of its subsidiaries taken as a whole to any “person” or “group” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company or one of its subsidiaries;
(2)    the adoption of a plan relating to the Company’s liquidation or dissolution;


A-11







(3)    the first day on which a majority of the members of the Board of Directors are not Continuing Directors of the Company; or
(4)    the consummation of any transaction or series of related transactions (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company or one of its wholly-owned subsidiaries, becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of the Voting Stock of the Company, measured by voting power rather than number of shares.
“Continuing Directors” means, as of any date of determination, any member of the Board of Directors of the Company who (1) was a member of such Board of Directors on the date of the issuance of the Securities or (2) was nominated for election or elected to such Board of Directors with the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination or election (either by a specific vote or by approval of the Company’s proxy statement in which such member was named as a nominee for election as a director).
“Voting Stock” means, with respect to any Person, Capital Stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such Person, even if the right so to vote has been suspended by the happening of such a contingency.
Section 4.    Sinking Fund
The Securities are not subject to any sinking fund.
Section 5.    Guaranty

The Securities are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.  A Securityholder may transfer or exchange Securities in accordance with the Indenture.  Upon any transfer or exchange, the Registrar and the Trustee may require a Securityholder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture.  The Registrar need not register the transfer of or exchange any Securities selected for redemption or to transfer or exchange any Securities for a period of 15 days prior to the mailing of a notice of redemption of Securities to be redeemed.


A-12







Section 7.    Persons Deemed Owners
The registered Holder of this Security may be treated as the owner of it for all purposes.
Section 8.    Unclaimed Money
If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request unless an abandoned property law designates another Person.  After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.
Section 9.    Discharge and Defeasance
Subject to certain conditions as set forth in the Indenture, the Company at any time may terminate some of or all its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.
Section 10.    Trustee Dealings with the Company
Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its affiliates and may otherwise deal with the Company or its affiliates with the same rights it would have if it were not Trustee.
Section 11.    No Recourse Against Others
A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation.  By accepting a Security, each Securityholder waives and releases all such liability.  The waiver and release are part of the consideration for the issue of the Securities.
Section 12.    Authentication
This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.


A-13







Section 13.    Governing Law
THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
Section 14.    CUSIP Numbers
Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Securityholders.  No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
Section 15.    Indenture
The Company will furnish to any Securityholder upon written request and without charge to the Securityholder a copy of the Indenture which has in it the text of this Security.
Section 16.    Reports
To the extent required to permit Securityholders (other than the Company’s affiliates and affiliates of any of the Subsidiary Guarantors) to sell their Securities without registration under the Securities Act, the Company will make publicly available the information concerning the Company specified in Rule 144(c)(2) under the Securities Act.
