If such redemption is subject to the satisfaction of one of more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), such redemption may not occur and such notice may be rescinded in the event that any or all of such conditions shall not have been satisfied (or waived by the Company in its sole discretion) by the redemption date, or by the redemption date so delayed.
(9)  DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Security or portion of a Security selected for redemption, except for the unredeemed portion of any Security being redeemed in part. Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days before a selection of Securities to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
(10)  PERSONS DEEMED OWNERS. The registered Holder of a Security may be treated as its owner for all purposes. 
(11)  AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Securities may be amended, supplemented or waived with the consent of the Holders of a majority in aggregate principal amount of the Securities (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities).  Without the consent of any Holder of a Security, the Indenture or the Securities may be amended, supplemented or waived (i) to cure any ambiguity, defect or inconsistency in the Indenture or the Securities in a manner that does not adversely affect the rights of any Holder, (ii) to provide for uncertificated Securities in addition to or in place of certificated Securities, (iii) to provide for the assumption of the Company’s obligations to Holders of Securities in the case of a merger or consolidation or sale of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, (iv) to make any change that would provide any additional rights or benefits to the Holders of Securities or that does not adversely affect the legal rights under any Indenture of any such Holder, (v) to comply with requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act, (vi) to conform the 

A-4

text of the Indenture or the Securities to any provision of a description of the Securities in the prospectus or prospectus supplement or other document relating to the offering of the Securities to the extent that such provision was intended to be a verbatim or substantially verbatim recitation of a provision of the Indenture or the Securities, which intent shall be evidenced by an Officer’s Certificate to that effect, (vii) modify or delete any provision of the Indenture, but only if the change or deletion becomes effective when there are no outstanding Securities which are entitled to the benefit of such provision as to which such modification or deletion would apply, (viii) to evidence and provide for the acceptance and appointment under the Indenture of a successor trustee pursuant to the requirements hereof or (ix) to provide for the issuance of additional Securities in accordance with the limitations set forth in the Indenture.
(12)  DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on the Securities; (ii) default in payment when due of the principal of, or premium, if any, on the Securities; (iii) failure by the Company to comply with any covenant in the Indenture (other than a default specified in clause (i) or (ii) above) for 60 days after written notice by the Trustee or Holders of at least 25% in principal amount of the Securities; (iv) default under any document evidencing any indebtedness for borrowed money represented by notes, bonds, debentures or other evidences of indebtedness by the Company, whether such indebtedness now exists or is created after the Issue Date, if that default: (a) is caused by a failure to pay principal when due at final (and not any interim) maturity on or prior to the expiration of any grace period provided in such indebtedness (a “Payment Default”); or (b) results in the acceleration of such indebtedness prior to its express maturity (without such acceleration having been rescinded, annulled or otherwise cured); and, in each case, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated (without such acceleration having been rescinded, annulled or otherwise cured), aggregates $100.0 million or more; provided that this clause (iv) shall not apply to (a) secured indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such indebtedness and (b) any indebtedness that is required to be converted into Qualifying Equity Interests upon the occurrence of certain designated events so long as no payments in cash or otherwise are required to be made in accordance with such conversion); and (v) (a) a court of competent jurisdiction (x) enters an order or decree under any Bankruptcy Law that is for relief against the Company or any of its Material Subsidiaries in an involuntary case; (y) appoints a custodian for all or substantially all of the property of the Company or any of its Material Subsidiaries; or (z) orders the liquidation of the Company or any of its Material Subsidiaries and, in each of clauses (x), (y) or (z), the order, appointment or decree remains unstayed and in effect for at least 60 consecutive days; or (b) the Company or any of its Material Subsidiaries, pursuant to or within the meaning of Bankruptcy Law, (w) commences a voluntary case; (x) consents to the entry of an order for relief against it in an involuntary case; (y) consents to the appointment of a custodian of it or for all or substantially all of its property; or (z) makes a general assignment for the benefit of its creditors. In the case of an Event of Default of the type specified in clause (v) above with respect to the Company or any Subsidiary of the Company that is a Material Subsidiary, all outstanding Securities will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then outstanding may declare all the Securities to be due and payable immediately. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Securities notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium, if any) if it in good faith determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount 

A-5

of the outstanding Securities by notice to the Trustee may, on behalf of the Holders of all of the Securities, waive an existing Default or Event of Default and its consequences under the Indenture except a Default or Event of Default in the payment of principal of, premium or interest, if any, on the Securities or in respect or a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of each outstanding Security.  The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Trustee is required, if any Default with respect to the Securities is known to the actual knowledge of a Responsible Officer of the Trustee, to deliver to the Holders a notice of such Default in accordance with the TIA. 
(13)  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.
(14)  NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company, as such, will 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. Each Holder of Securities by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities. The waiver may not be effective to waive liabilities under the federal securities laws. 
(15)  AUTHENTICATION. This Security will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 
(16)  ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
(17)  CUSIP AND ISIN NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Securities, and the Trustee may use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders. 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. 
(18)  GOVERNING LAW. THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS SECURITY WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF. 
The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
