The Special Redemption Notice will specify a redemption date for the notes (the “Special Redemption Date”), which will be no earlier than ten days and no later than 30 days after the date of the Special Redemption Notice. In connection with such redemption, the Offered Securities will be redeemable at a redemption price equal to 101% of the principal amount of the Offered Securities being redeemed, plus accrued and unpaid interest, if any, thereon to the Special Redemption Date.

In a Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Offered Securities repurchased, plus accrued and unpaid interest, if any, on the Offered Securities repurchased to the date of repurchase (a “Change of Control Payment”).

(d) On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all Offered Securities or portions of such Offered Securities properly tendered pursuant to the Change of Control Offer;

In addition, the Company shall not repurchase any Offered Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

(f) The Company shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Offered Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 1.3(3), the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section 1.3(3) by virtue of any compliance with such laws or regulations.

The Events of Default in Sections 6.01(a)(4), (5) and (6) of the Base Indenture are hereby deleted with respect to the Offered Securities and replaced with the following, which events shall constitute an “Event of Default” under Section 6.01(a) of the Base Indenture with respect to the Offered Securities so long as any of the Offered Securities remain Outstanding:

(4) default in the performance, or breach, of any covenant or agreement of the Company or, prior to the Distribution, the Guarantor and the related Guarantee (other than a default or breach that is specifically dealt with elsewhere in this Section 6.01), and continuance of such default or breach for a period of 90 days after the date on which there has been given, by registered or certified mail, to the Company and, prior to the Distribution, the Guarantor by the Trustee or to the Company and the Trustee, and, prior to the Distribution, the Guarantor by the Holders of at least 25% in principal amount of the Outstanding Securities of such series, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(6) the Company or, prior to the Distribution, the Guarantor shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator or similar official of the Company or, prior to the Distribution, the Guarantor or for any substantial part of its property, or make any general assignment for the benefit of creditors; or

Each of the following additional events shall be established and shall constitute an “Event of Default” under Section 6.01(a) of the Base Indenture with respect to the Offered Securities so long as any of the Offered Securities remain Outstanding:

(8) prior to the Distribution, the Guarantee with respect to the Offered Securities shall for any reason cease to be, or shall for any reason be asserted in writing by the Company or the Guarantor not to be, in full force and effect and enforceable in accordance with its terms except to the extent contemplated by this Indenture and such Guarantee; or

(9) an event of default shall happen and be continuing with respect to the Company’s or, prior to the Distribution, the Guarantor’s Indebtedness for borrowed money (other

than Non-Recourse Indebtedness) under any indenture or other instrument evidencing or under which the Company or, prior to the Distribution, the Guarantor shall have a principal amount outstanding (such amount with respect to original issue discount bonds or zero coupon notes, bonds or debentures or similar securities based on the accreted amount determined in accordance with United States generally accepted accounting principles and as of the date of the most recently prepared consolidated balance sheet of the Company or the Guarantor, as the case may be) in excess of $100,000,000, and such event of default shall involve the failure to pay the principal of such Indebtedness on the final maturity date thereof after the expiration of any applicable grace period with respect thereto, or such Indebtedness shall have been accelerated so that the same shall have become due and payable prior to the date on which the same would otherwise have become due and payable, and such acceleration shall not be rescinded or annulled within ten Business Days after notice thereof shall have been given by the trustee to the Company and, prior to the Distribution, the Guarantor or by the holders of at least 25% in aggregate principal amount of outstanding securities of such series to the trustee, the Company and, prior to the Distribution, the Guarantor; provided however that:

(i) if such event of default under such indenture or instrument shall be remedied or cured by the Company or the Guarantor or waived by the requisite holders of such Indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived without further action upon the part of either the Trustee or any of the Securityholders; and

(ii) subject to the provisions of Sections 7.01 and 7.02, the Trustee shall not be charged with knowledge of any such event of default unless written notice thereof shall have been given to the Trustee by the Company or the Guarantor, as the case may be, by the holder or an agent of the holder of any such Indebtedness, by the trustee then acting under any indenture or other instrument under which such default shall have occurred, or by the Holders of not less than 25% in the aggregate principal amount of Outstanding Securities of such series.

(1) Until the Distribution, references to “the Company” in Section 4.04 and 5.03 of the Base Indenture shall be deemed to refer to “the Guarantor”.

(2) Section 10.01(i) of the Base Indenture is hereby deleted with respect to the Offered Securities and replaced with the following:

(i) the Company shall be the continuing entity, or the successor entity or the Person which acquires by sale or conveyance substantially all the assets of the Company (if other than the Company), (A) shall expressly assume all of the obligations of the Company under the Indenture, (B) is an entity treated as a “corporation” for United States tax purposes and obtains either (x) an opinion, in form and substance reasonably acceptable to the Trustee, of tax counsel of recognized standing reasonably

acceptable to the Trustee, which counsel shall include Gibson, Dunn & Crutcher LLP, or (y) a ruling from the United States Internal Revenue Service, in either case to the effect that such merger or consolidation, or such sale or conveyance, will not result in an exchange of the Securities for new debt instruments for United States federal income tax purposes and (C) if such entity is not organized under the laws of the United States or any state of the United States, then it shall, with respect to the Offered Securities, expressly undertake obligations comparable to those initially undertaken by the Guarantor pursuant to Article II; ; provided, however, that no Additional Amounts shall be paid on account of any taxes imposed or withheld pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) (or any amended or successor version that is substantively comparable) and any current or future regulations promulgated thereunder or official interpretations thereof.

The Guarantor covenants that it will not merge or consolidate with any other Person or sell or convey all or substantially all of its assets to any Person, unless:

(i) the Guarantor shall be the continuing entity, or the successor entity or the Person which acquires by sale or conveyance substantially all the assets of the Guarantor (if other than the Guarantor), (A) shall expressly assume the due and punctual payment of the principal of, premium, if any, and interest on the notes or the obligations under the guarantees, as the case may be, according to their tenor, and the due and punctual performance and observance of all of the covenants and agreements of the indenture to be performed or observed by the Guarantor by supplemental indenture reasonably satisfactory to the trustee, executed and delivered to the trustee by such person, and (B) is an entity treated as a “corporation” for U.S. tax purposes and obtains either (x) an opinion, in form and substance reasonably acceptable to the Trustee, of tax counsel of recognized standing reasonably acceptable to the Trustee, which counsel shall include Gibson, Dunn & Crutcher LLP, or (y) a ruling from the U.S. Internal Revenue Service, in either case to the effect that such merger or consolidation, or such sale or conveyance, will not result in an exchange of the notes for new debt instruments for U.S. federal income tax purposes; and

(ii) no Event of Default and no event that, after notice or lapse of time or both, would become an Event of Default shall be continuing immediately after such merger or consolidation, or such sale or conveyance.

The Guarantor shall deliver to the Trustee prior to the consummation of the proposed transaction an Officer’s Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture comply with this Indenture.

(1) All payments by the Company under the Indenture and the Offered Securities are fully and unconditionally guaranteed by the Guarantor, to extent provided in the related Guarantee and the Indenture.

(2) At the time of the Distribution, the Guarantor shall be automatically and unconditionally released and discharged from all obligations under the Indenture and the Guarantee without any action required on the part of the Trustee or any holder of the Offered Securities. The release and discharge provided by this Section 1.7(2) shall be in addition to any defeasance, discharge or release of the Guarantee occurring pursuant to the other provisions of the Indenture, including Article XI and Section 15.03 of the Base Indenture.

(3) Upon the Company’s request and upon the delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that the Distribution has occurred, the Trustee shall execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations under the Indenture and Guarantee.

The Offered Securities may be redeemed, as a whole but not in part, at the option of the Company, upon not less than 30 nor more than 90 days notice (which notice shall be irrevocable), at a redemption price equal to 100% of the principal amount thereof, together with accrued interest, if any, to the redemption date and Additional Amounts (as defined in Section 3.2), if any, if as a result of any amendment to, or change in, the laws or regulations of Switzerland or the United States, as applicable, or any political subdivision thereof or therein having the power to tax (a “Taxing Jurisdiction”), or any change in the application or official interpretation of such laws, including any action taken by a taxing authority or a holding by a court of competent jurisdiction (regardless of whether such action or such holding is with respect to the Company or Guarantor), which amendment or change is announced or becomes effective after the date the Offered Securities are issued, the Guarantor or the Company has become, or there is a material probability that it will become, obligated to pay Additional Amounts on the next date on which any amount would be payable with respect to the Securities of such series, and such obligation cannot be avoided by the use of commercially reasonable measures available to Guarantor or the Company, as the case may be; provided, however, that (a) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which Guarantor or the Company, as the case may be, would be obligated to pay such Additional Amounts, and (b) at the time such notice of redemption is given, such obligation to pay such Additional Amounts remains in effect. Prior to the giving of any notice of redemption described in this paragraph, the Company or the Guarantor, as the case may be, shall deliver to the Trustee (i)(A) a certificate signed by two Officers of the Company stating that the obligation to pay Additional Amounts cannot be avoided by the Company taking commercially reasonable measures available to it or (B) a certificate signed by two Officers of the Guarantor stating that the obligation to pay

Additional Amounts cannot be avoided by Guarantor taking commercially reasonable measures available to it, and (ii) a written opinion of independent legal counsel to the Guarantor or the Company, as the case may be, of recognized standing to the effect that the Company has or there is a material probability that it will become obligated to pay Additional Amounts as a result of a change, amendment, official interpretation or application described above and that the Guarantor or the Company, as the case may be, cannot avoid the payment of such Additional Amounts by taking commercially reasonable measures available to it.

All payments made by the Guarantor under or with respect to the Guarantees will be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any Taxing Jurisdiction (“Taxes”), unless the Guarantor is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. In the event that Guarantor is required to so withhold or deduct any amount for or on account of any Taxes from any payment made under or with respect to the Guarantees, the Guarantor will pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each holder of Securities (including Additional Amounts) after such withholding or deduction will equal the amount that such Holder would have received if such Taxes had not been required to be withheld or deducted; provided that no Additional Amounts will be payable with respect to a payment to a holder of the Offered Securities or a holder of a beneficial interests in the Offered Securities where such holder is subject to taxation on such payment by a relevant Taxing Jurisdiction for any reason other than such holder’s mere ownership of the Offered Securities or for or on account of:

(a) any Taxes that are imposed or withheld solely because such holder or a fiduciary, settler, beneficiary, or member of such holder if such holder is an estate, trust, partnership, limited liability company or other fiscally transparent entity, or a person holding a power over an estate or trust administered by a fiduciary holder:

(b) any estate, inheritance, gift, sales, transfer, excise or personal property Taxes imposed with respect to the Securities, except as otherwise provided herein;

(c) any Taxes imposed solely as a result of the presentation of such Securities (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever is later, except to the extent that the beneficiary or holder thereof would have been entitled to the payment of Additional Amounts had the Securities been presented for payment on any date during such 30-day period;

(d) any Taxes imposed solely as a result of the failure of such holder or any other person to comply with applicable certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of such holder, if such compliance is required by statute or regulation of the relevant Taxing Jurisdiction as a precondition to relief or exemption from such Taxes;

(e) with respect to withholding Taxes imposed by the United States, any such Taxes imposed by reason of the failure of such holder to fulfill the statement requirements of sections 871(h) or 881(c) of the Code;

(f) any Taxes that are payable by any method other than withholding or deduction by the Guarantor or the Company or any paying agent from payments in respect of such Securities;

(g) any Taxes required to be withheld by any paying agent from any payment in respect of any Securities if such payment can be made without such withholding by at least one other paying agent;

(h) any Taxes required to be deducted or withheld pursuant to the European Council Directive 2003/48/EC of June 3, 2003 on the taxation of savings income in the form of interest payments, or any amendment thereof, or any law implementing or complying with, or introduced in order to conform to, that Directive or the Luxembourg Law of December 23, 2005, as amended;

(i) any withholding or deduction for Taxes which would not have been imposed if the relevant Securities had been presented to another paying agent in a Member State of the European Union; or

(j) any combination of Section 3.02(a), (b), (c), (d), (e), (f), (g), (h) and (i).

Additional Amounts will not be payable to or for the account of any Holder or the holder of a beneficial interest in an Offered Security if such payment would not be subject to such withholding or deduction of Taxes but for the failure of a Holder or the holder of a beneficial interest in an Offered Security to make a valid declaration of non-residence or other similar

claim for exemption or to provide a certificate declaring its non-residence, if the Company were treated as a domestic corporation under United States federal income tax and if (x) the making of such declaration or claim or the provision of such certificate is required or imposed by statute, treaty, regulation, ruling or administrative practice of the relevant Taxing Authority as a precondition to an exemption from, or reduction in, the relevant Taxes, and (y) at least 90 days prior to the first payment date with respect to which the Guarantor shall apply this paragraph, the Guarantor shall have notified all Holders of Offered Securities in writing that they shall be required to provide such declaration or claim.

Additional Amounts also will not be payable to any Holder or the holder of a beneficial interest in an Offered Security that is a fiduciary, partnership, limited liability company or other fiscally transparent entity, or to such holder that is not the sole Holder or holder of such beneficial interests of such Offered Security, as the case may be. This exception, however, will apply only to the extent that a beneficiary or settlor with respect to the fiduciary, or a beneficial owner or member of the partnership, limited liability company or other fiscally transparent entity, would not have been entitled to the payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment.

In addition, no Additional Amounts will be paid on account of any Taxes imposed or withheld pursuant to Sections 1471 through 1474 of the Code (or any amended or successor version that is substantively comparable) and any current or future regulations promulgated thereunder or official interpretations thereof.

The Guarantor will also (i) make such withholding or deduction of Taxes and (ii) remit the full amount of Taxes so deducted or withheld to the relevant Taxing Jurisdiction in accordance with all applicable laws. The Guarantor will use its commercially reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Taxing Authority imposing such Taxes. The Guarantor will, upon request, make available to the holders of the Offered Securities, within 90 days after the date the payment of any Taxes so deducted or withheld is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Guarantor or if, notwithstanding Guarantor’s efforts to obtain such receipts, the same are not obtainable, other evidence of such payments by Guarantor.

At least 30 days prior to each date on which any payment under or with respect to the Guarantees is due and payable, if the Guarantor will be obligated to pay Additional Amounts with respect to such payment, the Guarantor will deliver to the Trustee an Officer’s Certificate stating the fact that such Additional Amounts will be payable, the amounts so payable and will set forth such other information as is necessary to enable such Trustee to pay such Additional Amounts to holders of Offered Securities on the payment date.

The provisions of this Article II shall survive any termination of the discharge of this Indenture and shall apply mutatis mutandis to any jurisdiction in which the Guarantor or any successor Person to the Guarantor is organized or is engaged in business for tax purposes or any political subdivisions or taxing authority or agency thereof or therein; provided, however, the date on which the Guarantor changes its jurisdiction in which it is organized or such Person becomes a successor to the Guarantor shall be substituted for the date on which the Offered Securities was issued.

Whenever in this Indenture, the Securities or the Guarantees there is mentioned, in any context, the payment of principal and premium, if any, redemption price, interest or any other amount payable under or with respect to any Security, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

Capitalized terms used but not defined in this Second Supplemental Indenture shall have the meanings ascribed thereto in the Base Indenture.

The Base Indenture, as supplemented and amended by this Second Supplemental Indenture, is in all respects ratified and confirmed, and the Base Indenture, this Second Supplemental Indenture and all indentures supplemental thereto shall be read, taken and construed as one and the same instrument.

In carrying out the Trustee’s responsibilities hereunder, the Trustee shall have all of the rights, protections and immunities which it possesses under the Indenture. The recitals contained herein and in the Offered Securities, except the Trustee’s certificate of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to (i) the validity or sufficiency of this Second Supplemental Indenture or of the Offered Securities, (ii) the proper authorization hereof by the Company by action or otherwise, (iii) the due execution hereof by the Company or (iv) the consequences of any amendment herein provided for. The Trustee shall not be accountable for the use or application by the Company of the Offered Securities or the proceeds thereof.

This Second Supplemental Indenture and the Offered Securities shall be deemed to be a contract made under the internal laws of the State of New York, and for all purposes shall be construed in accordance with the laws of said State without regard to conflicts of law principles that would require the application of any other law. This Second Supplemental Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of this Second Supplemental Indenture and shall, to the extent applicable, be governed by such provisions.

In case any one or more of the provisions contained in this Second Supplemental Indenture or in the Offered Securities of any series shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Second Supplemental Indenture or of such Offered Securities, but this Second Supplemental Indenture and such Offered Securities shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or therein.

This Second Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Second Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Second Supplemental Indenture as to the parties hereto and may be used in lieu of the original Second Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

Nothing in this Second Supplemental Indenture, express or implied, shall give to any Person other than the parties hereto and their successors or assigns, and the Holders of the Offered Securities, any benefit or legal or equitable rights, remedy or claim under this Second Supplemental Indenture or the Base Indenture.

This Second Supplemental Indenture and the Offered Securities are subject to the provisions regarding supplemental indentures and amendments set forth in Article IX of the Base Indenture.

The Company hereby represents and warrants that, assuming the due authorization, execution and delivery of this Second Supplemental Indenture by the Trustee, this Second Supplemental Indenture is its legal, valid and bind obligation enforceable against it in accordance with its terms.

IN WITNESS WHEREOF, the parties hereto have caused this Second Supplemental Indenture to be duly executed all as of the day and year first above written.

This security is one of a duly authorized series of debt securities of The ADT Corporation, a Delaware company (the “Company”), issued or to be issued in one or more series under and pursuant to an Indenture for the Company’s unsubordinated debt securities, dated as of July 5, 2012 (the “Base Indenture”), duly executed and delivered by and among the Company and Wells Fargo Bank, National Association (the “Trustee”), as supplemented by the Second Supplemental Indenture, dated as of July 5, 2012 (the “Second Supplemental Indenture”), by and among the Company, Tyco International Ltd. (the “Guarantor”) and the Trustee. The Base Indenture as supplemented and amended by the Second Supplemental Indenture is referred to herein as the “Indenture.” By the terms of the Base Indenture, the debt securities issuable thereunder are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Base Indenture. This security is one of the series designated on the face hereof (individually, a “Security,” and collectively, the “Securities”), and reference is hereby made to the Indenture for a description of the rights, limitations of rights, obligations, duties and immunities of the Trustee, the Company, Guarantor and the holders of the Securities (the “Securityholders”). Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Base Indenture or the Second Supplemental Indenture, as applicable.

1. Interest. The Company promises to pay interest on the principal amount of this Security at an annual rate of 3.500%. The Company will pay interest semi-annually on January 15 and July 15 of each year (each such day, an “Interest Payment Date”). If any Interest Payment Date, redemption date or maturity date of this Security is not a Business Day, then payment of interest or principal (and premium, if any) shall be made on the next succeeding Business Day with the same force and effect as if made on the date such payment was due, and no interest shall accrue for the period after such date to the date of such payment on the next succeeding Business Day. Interest on the Securities will accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Security is authenticated between a regular record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; and provided, further, that the first Interest Payment Date shall be January 15, 2013. Interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest), if any, to the persons in whose name such Securities are registered at the close of business on the regular record date referred to on the facing page of this Security for such interest installment. In the event that the Securities or a portion thereof are called for redemption and the Redemption Date is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest on such Securities will be paid upon presentation and surrender of such Securities as provided in the Indenture. The principal of and the interest on the Securities shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and private debt, at the office or agency of the Company maintained for that purpose in accordance with the Indenture.

3. Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association, the Trustee, will act as paying agent and Security Registrar. The Company may change or appoint any paying agent or Security Registrar without notice to any Securityholder. The Company or any of its Subsidiaries may act in any such capacity.

4. 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 of 1939 (“TIA”) as in effect on the date the Indenture is qualified. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and TIA for a statement of such terms. The Securities are unsecured general obligations of the Company and constitute the series designated on the face hereof as the “3.500% Notes due 2022”, initially limited to $1,000,000,000 in aggregate principal amount.

The Company will furnish to any Securityholder upon written request and without charge a copy of the Base Indenture and the Second Supplemental Indenture. Requests may be made to: The ADT Corporation, 1501 Yamato Road, Boca Raton, FL 33431, Attention: Investor Relations.

5. Optional Redemption. The Securities will be subject to redemption at the option of the Company on any date prior to the maturity date, in whole or from time to time in part, in $1,000 increments (provided that any remaining principal amount thereof shall be at least the minimum authorized denomination thereof), on written notice given to the Securityholders thereof not less than 30 days nor more than 90 days prior to the date fixed for redemption in such notice (the “Redemption Date”). The Securities will be redeemable at a redemption price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed and (ii) as determined by the Quotation Agent and delivered to the Trustee in writing, the sum of the present values of the remaining scheduled payments of principal and interest thereon due on any date after the Redemption Date (excluding the portion of interest that will be accrued and unpaid to and including the Redemption Date) discounted from their scheduled date of payment to the Redemption Date (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Redemption Treasury Rate plus 30 basis points, plus, in either the case of clause (i) or clause (ii), accrued and unpaid interest, if any, thereon to the Redemption Date. This Security is also subject to redemption to the extent provided in Article II of the Second Supplemental Indenture.

If the giving of the notice of redemption is completed as provided in the Indenture, interest on such Securities or portions of Securities shall cease to accrue on and after the Redemption Date, unless the Company shall default in the payment of any such redemption price and accrued interest with respect to any such Security or portion thereof.

The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities.

6. Special Redemption. The Securities will be subject to redemption at the option of the Company if the Distribution has not occurred on or prior to March 31, 2013 or if the Board of

Directors of the Guarantor determines that the Distribution Date will not occur by March 31, 2013. The Company may elect to redeem the Securities by issuing a special redemption notice on or prior to June 30, 2013. The Special Redemption Notice will specify a redemption date for the notes (the “Special Redemption Date”), which will be no earlier than 10 days and no later than 30 days after the date of the Special Redemption Notice. In connection with such redemption, the Securities will be redeemable at a redemption price equal to 101% of the principal amount of the Securities being redeemed, plus accrued and unpaid interest, if any, thereon to the Special Redemption Date.

If the giving of the Special Redemption Notice is completed as provided in the Indenture, interest on such Securities or portions of Securities shall cease to accrue on and after the Special Redemption Date, unless the Company shall default in the payment of any such redemption price and accrued interest with respect to any such Security or portion thereof.

6. Change of Control Triggering Event. If a Change of Control Triggering Event occurs, unless the Company has exercised its option to redeem this Security, it shall be required to make an offer to the holder of this Security to repurchase, at such holder’s election, all or a part (equal to $1,000 or an integral multiple of $1,000 in excess thereof; provided that any remaining principal amount thereof shall be at least the minimum authorized denomination thereof), of this Security, in cash equal to 101% of the aggregate principal amount of this Security repurchased, plus accrued and unpaid interest, if any, to the date of repurchase. Within 30 days following any Change of Control Triggering Event, or at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control Triggering Event, a notice shall be mailed to each Holder describing in reasonable detail the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase this Security on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed.

7. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in the denominations of $2,000 or any integral multiple of $1,000 in excess thereof. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Securities may be presented for exchange or for registration of transfer (duly endorsed or with the form of transfer endorsed thereon duly executed if so required by the Company or the Security Registrar) at the office of the Security Registrar or at the office of any transfer agent designated by the Company for such purpose. No service charge will be made for any registration of transfer or exchange, but a Securityholder may be required to pay any applicable taxes or other governmental charges.

Any funds or Governmental Obligations deposited with any paying agent or the Trustee, or then held by Guarantor or the Company, in trust for payment of principal of, premium, if any, or interest on the Securities of a particular series that are not applied but remain unclaimed by the holders of such Securities for at least one year after the date upon which the principal of, premium, if any, or interest on such Securities shall have respectively become due and payable, shall be repaid to Guarantor or the Company, as applicable, or (if then held by Guarantor or the Company) shall be discharged from such trust. After return to the Company or Guarantor, Holders entitled to the money or securities must look to the Company or Guarantor, as applicable, for payment as unsecured general creditors.

10. Amendments, Supplements and Waivers. The Base Indenture contains provisions permitting the Company, Guarantor and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the securities of each series at the time Outstanding affected by such supplemental indenture or indentures to enter into supplemental indentures for the purpose of adding, changing or eliminating any provisions of the Base Indenture or any supplemental indenture or of modifying in any manner not covered elsewhere in the Base Indenture the rights of the holders of the securities of such series; provided, however, that no such supplemental indenture, without the consent of the holders of each Security then Outstanding and affected thereby, shall: (i) extend a fixed maturity of or any installment of principal of any Securities of any series or reduce the principal amount thereof, or reduce the amount of principal of any original issue discount security that would be due and payable upon declaration of acceleration of the maturity thereof; (ii) reduce the rate of or extend the time for payment of interest of any Security of any series; (iii) reduce the premium payable upon the redemption of any Security; (iv) make any Security payable in Currency other than that stated in the Security; (v) impair the right to institute suit for the enforcement of any payment on or after the fixed maturity thereof (or in the case or redemption, on or after the redemption date); or (vi) reduce the percentage of Securities, the holders of which are required to consent to any such supplemental indenture or indentures. The Base Indenture also contains provisions permitting the holders of not less than a majority in aggregate principal amount of the Outstanding securities of each series affected thereby, on behalf of all of the holders of the securities of such series, to waive any past Default under the Base Indenture, and its consequences, except a Default in the payment of the principal of, premium, if any, or interest on any security of such series or a Default in respect of a covenant or provision of the Base Indenture that cannot be modified or amended without the consent of the holder of each Outstanding security of such affected series. Any such consent or waiver by the registered Securityholder shall be conclusive and binding upon such holder and upon all future holders and owners of this Security and of any Security issued in exchange for this Security or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Security.

11. Defaults and Remedies. If an Event of Default with respect to the securities of a series issued pursuant to the Base Indenture occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the Securities of such series then Outstanding, by notice in writing to the Company and, prior to the Distribution Date, the Parent (and to the

Trustee if notice is given by such holders), may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. Subject to the terms of the Indenture, if an Event of Default under the Indenture shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders, unless such holders have offered the Trustee indemnity satisfactory to it. Upon satisfaction of certain conditions set forth in the Indenture, the holders of a majority in principal amount of the Outstanding securities of a series issued pursuant to the Base Indenture 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 securities of such series.

12. Trustee, Paying Agent and Security Registrar May Hold Securities. The Trustee, subject to certain limitations imposed by the TIA, or any paying agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not Trustee, paying agent or Security Registrar.

13. No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement of the Indenture, or of any Security, or for any claim based thereon or otherwise in respect hereof or thereof, shall be had against any incorporator, stockholder, officer or director, past, present or future as such, of the Guarantor or the Company or of any predecessor or successor corporation, either directly or through the Guarantor or the Company or any such predecessor or successor corporation, 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 the Indenture and the obligations issued hereunder and thereunder 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 Guarantor or the Company or of any predecessor or successor corporation, or any of them, because of the creation of the indebtedness authorized by the Indenture, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in the Securities 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 authorized by the Indenture, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in the Securities or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the acceptance of the Securities.

14. Discharge of Indenture. The Indenture contains certain provisions pertaining to defeasance, which provisions shall for all purposes have the same effect as if set forth herein.

15. Authentication. This Security shall not be valid until the Trustee signs the certificate of authentication attached to the other side of this Security.

16. Guarantee and Unconditional Release of Guarantee. All payments by the Company under the Indenture and this Security are fully and unconditionally guaranteed to the holder of this Security by the Guarantor, as provided in the related Guarantee and the Indenture. At the time of the Distribution, the Guarantor shall be automatically and unconditionally released and discharged from all obligations under the Indenture and the Guarantee without any action required on the part of the Trustee or any holder of the Offered Securities.
