“Trigger Period” means the period commencing on the earlier of (a) the first public notice of the occurrence of a Change of Control or (b) the public announcement by the Company of its intention to effect a Change of Control, and ending 60 days following consummation of such Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for a possible rating downgrade by any of the Rating Agencies on such 60th day, such extension to last with respect to each such Rating Agency until the date on which such Rating Agency considering such possible rating downgrade either (x) rates the Notes below Investment Grade or (y) publicly announces that it is no longer considering the Notes for a possible downgrade).

(b) Such Additional Notes shall be consolidated and form a single series with, and shall have the same terms as to ranking, redemption, waivers, amendments or otherwise, as the Initial Notes and shall vote together as one class on all matters with respect to the Initial Notes.

(c) The Company may, to the extent permitted by law, directly or indirectly (regardless of whether such Notes are surrendered to the Company), purchase Notes in the open market, negotiated transactions or otherwise, whether by the Company or one or more of its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives.

REDEMPTION OF SECURITIES

Section 4.01 Optional Redemption.

(a) Subject to Section 1.02 hereof, the provisions of Article III of the Base Indenture, as supplemented by the provisions of this Supplemental Indenture, shall apply to the Notes.

13

(b) Prior to the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (i)(x) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (y) interest accrued to the date of redemption, and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date. On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

(c) The Company will be responsible for making calculations called for under the Notes, including, but not limited, to the determination of the redemption price and any other amounts payable on the Notes. The Company will provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations without independent verification. The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall not be responsible or liable for any determination, calculation, or verification of the redemption price.

(d) Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed (with a copy to the Trustee). Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent and, at 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), or the redemption date may not occur at all and such notice may be rescinded if all such conditions shall not have been satisfied (or waived by the Company in its sole discretion). The Company shall provide written notice to the Trustee prior to the close of business one Business Day prior to the redemption date if any such redemption has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption as given. The Trustee shall, at the Company’s written request (delivered to the Trustee at least five Business Days prior to the date such notice is to be sent (or such shorter period as the Trustee may agree) with a copy of such notice) give the notice of redemption in the Company’s name and at the Company’s expense. Such notice shall state the redemption price (if known) or the formula pursuant to which the redemption price is to be determined if the redemption price cannot be determined at the time the notice is given. If the redemption price cannot be determined at the time such notice is to be given, the actual redemption price, calculated as set forth in the Indenture, shall be set forth in an Officer’s Certificate delivered to the Trustee no later than two Business Days prior to the redemption date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

(e) In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal

14

amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

(f) Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes, or portions thereof, called for redemption.

(g) If any redemption date would otherwise be a day that is not a Business Day, the related payment of principal and interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a redemption date shall be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date in accordance with the provisions of the Notes and the Indenture.

(h) On or before the redemption date for the Notes, the Company shall deposit with the Trustee or a Paying Agent funds sufficient to pay the redemption price of the Notes to be redeemed on the redemption date, and (except if the redemption date shall be an Interest Payment Date) accrued interest, if any.

Section 4.02 Purchase of Notes upon a Change of Control Repurchase Event.

(a) If a Change of Control Repurchase Event occurs, unless the Company shall have exercised its option to redeem the Notes pursuant to Section 4.01 of this Supplemental Indenture, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes to be repurchased, plus any accrued and unpaid interest on the Notes to, but excluding, the repurchase date. Within 30 days following any Change of Control Repurchase Event or, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase the Notes on the repurchase date specified in the notice at the option of the Holders, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered. The Change of Control Notice shall, if delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Notes is conditioned on a Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date.

15

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

(i) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the Change of Control Notice;

(ii) no later than 11:00 a.m., New York City time on the Change of Control Payment Date, deposit with the Paying Agent or tender agent appointed for such purpose an amount equal to the aggregate repurchase price in respect of all the Notes or portions of the Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officer’s Certificate stating the aggregate principal amount of Notes being repurchased by the Company.

(c) The Paying Agent or tender agent shall promptly deliver to each Holder of Notes properly tendered the repurchase price for the Notes, and the Trustee, upon receipt of a Company Order (and an Officer’s Certificate and an Opinion of Counsel), shall promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered.

(d) Notwithstanding the foregoing in this Section 4.02, the Company shall not be required to make a Change of Control Offer in connection with a Change of Control Repurchase Event if a third party makes such an offer in connection with such Change of Control Repurchase Event in the manner and at the times required and otherwise in compliance with the requirements for such a Change of Control Offer made by the Company, and such third party purchases all Notes properly tendered and not withdrawn under its offer.

(e) If Holders of not less than 90% in aggregate principal amount then outstanding validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company pursuant to Section 4.02(d) hereof, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 10 days nor more than 60 days’ prior written notice to the Holders of the Notes (with a copy to the Trustee), given not more than 30 days following such purchase pursuant to the Change of Control Offer described in Section 4.02(b) hereof, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding the redemption date (subject to the right of Holders of record on a Record Date to receive interest on the relevant Interest Payment Date).

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent the provisions of any such securities laws or regulations conflict with this Section 4.02, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.02 by virtue thereof.

(g) The Trustee shall not be responsible or liable for determining whether any Change of Control and/or Change of Control Repurchase Event has occurred and whether any payment with respect to the Notes is required in connection with any Change of Control Repurchase Event. The Trustee shall not be responsible for monitoring the ratings of the Company and the Guarantors or their Affiliates or any other party or making any request upon any rating agency.

(c) For the avoidance of doubt, the inclusion of specific Liens in clauses (i) through (xx) of Section 5.01(b) hereof shall not create any implication that the Indebtedness or guarantees of Indebtedness secured by such Liens constitute Indebtedness of the Company, any Guarantor or any Restricted Subsidiary.

(e) For purposes of this Section 5.01, in the event that a Lien meets the criteria of more than one of the types of Liens permitted pursuant to Section 5.01(b) or (d), the Company, in its sole discretion, will classify, and may reclassify, such Lien and only be required to include the amount and type of such Lien as a Lien or a Lien permitted by Section 5.01(b), and a Lien may be divided and classified and reclassified into more than one of such types of Liens. In addition, for purposes of Section 5.01(b), in no event will the amount of any such Indebtedness or guarantees of Indebtedness be required to be included more than once despite the fact more than one person

20

is or becomes liable with respect to such Indebtedness or guarantees of Indebtedness and despite the fact such Indebtedness or guarantees of Indebtedness are secured by the assets of more than one person (for example, and for avoidance of doubt, in the case where there are Liens on assets of one or more of the Company, the Guarantors and the Restricted Subsidiaries securing any Indebtedness or guarantees of Indebtedness, the amount of such Indebtedness and guarantees of Indebtedness secured shall only be included once for purposes of such calculations).

(iii) such transaction involves a lease for not more than three years (or which may be terminated by the Company, any Guarantor or any Restricted Subsidiary within a period of not more than three years);

(iv) the Company, any Guarantor or any Restricted Subsidiary would be entitled to incur Indebtedness secured by a Lien with respect to such sale and leaseback transaction without equally and ratably securing the Notes pursuant to Section 5.01(b) of this Supplemental Indenture (except with respect to a Lien permitted by Section 5.01(b)(xix) of this Supplemental Indenture); or

(v) the Company or any Guarantor applies (or to the extent the proceeds are received directly by any Restricted Subsidiary, such Restricted Subsidiary applies) an amount equal to the net proceeds from the sale of such Property to the purchase of other Property or assets used or useful in the Company’s or such Guarantor’s business or to the retirement of the Company’s or such Guarantor’s Indebtedness or any Guarantee that is pari passu in right of payment with the Notes or any Guarantee within 365 days before or after the effective date of any such sale and leaseback transaction; provided that, in lieu of applying such amount to the retirement of pari passu Indebtedness, the Company may deliver Notes with an aggregate outstanding amount equal to such net proceeds to the Trustee for cancellation as provided in Section 3.03(c) of this Supplemental Indenture.

21

(b) Notwithstanding the restrictions set forth in Section 5.02(a) hereof, the Company, any Guarantor and any Restricted Subsidiary may enter into any sale and leaseback transaction that would otherwise be subject to the restrictions set forth in Section 5.02(a) hereof, if after giving effect thereto the aggregate amount of all Attributable Debt with respect to such transactions (not including Attributable Debt permitted under clauses (i) through (v) of Section 5.02(a) hereof), together with all Indebtedness outstanding pursuant to Section 5.01(c) of this Supplemental Indenture, does not exceed an amount equal to the greater of (x) $770 million, and (y) 15% of the Company’s Consolidated Net Tangible Assets.

Section 5.03 Additional Note Guarantees. After the Issue Date, the Company will not permit any of its existing or future Subsidiaries to become an obligor with respect to any Indebtedness under the Senior Credit Facilities unless such Subsidiary, within 45 days, executes and delivers a supplemental indenture substantially in the form of supplemental indenture appearing as Exhibit B hereto providing for a Guarantee by such Subsidiary of the Notes.

ARTICLE VII

GUARANTEE

Section 7.01 Guarantee.

(a) Subject to the provisions of this Article VII, each Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder and the Trustee, the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Notes and all other obligations and liabilities of the Company under this Supplemental Indenture, including, without limitation, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Company or any Guarantor, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).

(b) Each Guarantor agrees that the Guaranteed Obligations will rank equally in right of payment with all of such Guarantor’s existing and future senior, unsecured Indebtedness, will rank senior in right of payment to all of such Guarantor’s existing and future unsecured, subordinated Indebtedness, will be effectively subordinated to all of such Guarantor’s existing and future secured Indebtedness, to the extent of the value of the assets securing such Indebtedness, and will be structurally subordinated to all of the existing and future Indebtedness (including trade payables) of such Guarantor’s non-Guarantor Subsidiaries (other than Indebtedness and liabilities owed to such Guarantor, if any).

23

(c) Each Guarantor agrees that its guarantee set forth in this Section 7.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such guarantee on the Notes.

(d) Each Guarantor further agrees (to the extent permitted by law) that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Article VII notwithstanding any extension or renewal of any Guaranteed Obligation.

(e) Each 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 Guarantor waives notice of any default under the Notes or the Guaranteed Obligations.

(f) Each Guarantor further agrees that its guarantee herein will constitute a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guaranteed Obligations.

(g) Except as set forth in Section 7.02, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guaranteed Obligations in full), 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 Guaranteed Obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other person under this Supplemental Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Supplemental Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder for the Guaranteed Obligations; (e) the failure of any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the ownership of the Company; (g) any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations; or (h) any other act or thing or omission or delay to do any other act or thing that may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

(h) Each Guarantor agrees that its guarantee herein shall remain in full force and effect until payment in full of all the Guaranteed Obligations or such Guarantor is released from its guarantee in compliance with Section 7.02. Each Guarantor further agrees that its guarantee 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, premium, if any, interest on any of the Guaranteed Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

24

(i) In furtherance of the foregoing and not in limitation of any other right that any Holder has at law or in equity against each Guarantor by virtue hereof, upon the failure of the Company to pay any of the Guaranteed Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor shall promise to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee on behalf of the Holders, an amount equal to the sum of (i) the unpaid amount of such Guaranteed Obligations then due and owing and (ii) accrued and unpaid interest on such Guaranteed Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Company or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding).

(j) Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in this Supplemental Indenture for the purposes of its guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guaranteed Obligations, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of its guarantee.

(k) Each Guarantor also agrees to pay any and all fees, costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under this Section 7.01.

Section 7.02 Limitation on Liability; Termination, Release and Discharge.

(a) Any term or provision of this Supplemental Indenture to the contrary notwithstanding, the obligations of each Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its guarantee or pursuant to its contribution obligations under this Supplemental Indenture, result in the obligations of such Guarantor under its guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal, foreign, state or provincial law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

(b) Any Guarantor will be released and discharged automatically and unconditionally from all its obligations under this Supplemental Indenture and its guarantee and will cease to be a Guarantor, without any further action required on the part of the Trustee or any Holder:

(i) if the Company exercises its legal defeasance or its covenant defeasance options with respect to the Notes or if its obligations under the Indenture are discharged in accordance with the terms of the Indenture;

(ii) if no Event of Default has occurred and is then continuing, upon the liquidation or dissolution of such Guarantor; and

(iii) upon the release or discharge of such Guarantor’s obligations under the Senior Credit Facilities.

25

(c) Upon delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that any of the conditions described in Section 7.02(b) hereof have occurred or otherwise been satisfied, the Trustee shall, at the Company’s expense, execute any supplemental indenture or other documents reasonably requested by the Company in order to evidence the release of a Guarantor from its obligations under its guarantee and this Supplemental Indenture.

Section 7.03 Right of Contribution. Each Guarantor shall agree that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Company or any other Guarantor who has not paid its proportionate share of such payment. The provisions of this Section 7.03 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor hereunder.

Section 7.04 No Subrogation. Notwithstanding any payment or payments made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Company or any other Guarantor or guarantee or right of offset held by the Trustee or any Holder for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Guaranteed Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Guaranteed Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Guaranteed Obligations.

(1) Interest. Microchip Technology Incorporated, a Delaware corporation (such corporation, and its successors and assigns under the Indenture referred to below, being herein called the “Company”), promises to pay interest on the principal amount of this Note at the interest rate per annum shown above. The Company shall pay interest semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024. Interest on the Notes shall accrue from March 7, 2024 and shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

(2) Method of Payment. The Company shall pay interest on the Notes (subject to Section 2.13 of the Base Indenture, in the case of Defaulted Interest) to the persons who are registered Holders of Notes at the close of business on the Record Date immediately preceding the Interest Payment Date even if such Notes are canceled after the Record Date and on or before the Interest Payment Date. Holders of certificated Notes must surrender certificated Notes to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payment of principal of and premium, if any, and interest on this Note shall be made in immediately available funds to the Depositary or its nominee, as the case may be, as the registered Holder of this Global Note.

(3) Paying Agent, Transfer Agent and Registrar. Initially, Computershare Trust Company, National Association, as trustee (the “Trustee”) under the Indenture (as defined below), shall act as Paying Agent, transfer agent and Registrar. The Company may change any Paying Agent, transfer agent, Registrar or co-registrar without notice to the Holders. The Company may act as Paying Agent, transfer agent, Registrar or co-registrar.

(4) Indenture. This Note is a “Security,” and the Notes are “Securities” issued under the Indenture, dated as of February 29, 2024 (the “Base Indenture”), as supplemented by the Supplemental Indenture, dated as of March 7, 2023, (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and the Trustee. The Notes are unsecured general obligations of the Company and constitute the “5.050% Senior Notes due 2029,” initially limited to $1,000,000,000 in aggregate principal amount. The terms of the Notes include those stated in the Indenture. Capitalized terms used herein but not defined herein are used as defined in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

(5) Optional Redemption. Prior to February 15, 2029, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(a)(i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on February 15, 2029) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (ii) interest accrued to the date of redemption, and

A-4

(b) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after February 15, 2029, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date.

The Company will be responsible for making calculations called for under the Notes, including, but not limited, to the determination of the redemption price and any other amounts payable on the Notes. The Company will provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations without independent verification. The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall not be responsible or liable for any determination, calculation, or verification of the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed (with a copy to the Trustee). Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent and, at 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), or the redemption date may not occur at all and such notice may be rescinded if all such conditions shall not have been satisfied (or waived by the Company in its sole discretion). The Company shall provide written notice to the Trustee prior to the close of business one Business Day prior to the redemption date if any such redemption has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption as given. The Trustee shall, at the Company’s written request (delivered to the Trustee at least five Business Days prior to the date such notice is to be sent (or such shorter period as the Trustee may agree) with a copy of such notice) give the notice of redemption in the Company’s name and at the Company’s expense. Such notice shall state the redemption price (if known) or the formula pursuant to which the redemption price is to be determined if the redemption price cannot be determined at the time the notice is given. If the redemption price cannot be determined at the time such notice is to be given, the actual redemption price, calculated as set forth in the Indenture, shall be set forth in an Officer’s Certificate delivered to the Trustee no later than two Business Days prior to the redemption date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

A-5

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes, or portions thereof, called for redemption.

If any redemption date would otherwise be a day that is not a Business Day, the related payment of principal and interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a redemption date shall be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date in accordance with the provisions of the Notes and the Indenture.

On or before the redemption date for the Notes, the Company shall deposit with the Trustee or a Paying Agent funds sufficient to pay the redemption price of the Notes to be redeemed on the redemption date, and (except if the redemption date shall be an Interest Payment Date) accrued interest, if any.

(6) Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs, unless the Company shall have exercised its option pursuant to Section (5) hereof to redeem the Notes, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes to be repurchased plus any accrued and unpaid interest on such Notes to, but excluding, the repurchase date.

Within 30 days following any Change of Control Repurchase Event with respect to the Notes or, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each Holder of the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase such Notes on the repurchase date specified in the notice at the option of the Holders, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered. The Change of Control Notice shall, if delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Notes is conditioned on a Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date.

A-6

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

(a) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the Change of Control Notice;

(b) no later than 11:00 a.m., New York City time on the Change of Control Payment Date, deposit with the Paying Agent or tender agent appointed for such purpose an amount equal to the aggregate repurchase price in respect of all the Notes or portions of the Notes properly tendered; and

(c) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officer’s Certificate stating the aggregate principal amount of the Notes being repurchased by the Company.

If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company pursuant to Section 4.02(d) of the Supplemental Indenture, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 10 nor more than 60 days’ prior written notice to the Holders of the Notes (with a copy to the Trustee), given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of Holders of record on a Record Date to receive interest on the relevant Interest Payment Date).

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent the provisions of any such securities laws or regulations conflict with this Section (6), the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section (6) by virtue thereof.

(7) Denominations; Transfer; Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and any multiple of $1,000 in excess thereof. The transfer of Notes may be registered, and Notes may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Company shall not be required (A) to transfer or exchange any Notes subject to redemption during a period beginning at the opening of business 15 days before the day of the electronic delivery or mailing of a notice of redemption and ending at the close of business on the day of such electronic delivery or mailing or (B) to register the transfer of or exchange any Note so selected for redemption, in whole or in part, except the unredeemed portion of any Note being redeemed in part.

A-7

(8) Defeasance. Subject to certain conditions as provided in the Indenture, the Company at any time may terminate some or all of its obligations under the Notes and the Indenture if the Company deposits with the Trustee money and/or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to their Stated Maturity.

(9) Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes, except that interest (subject to Section 2.13 of the Base Indenture, in the case of Defaulted Interest) shall be paid to the person that was the registered Holder on the relevant Record Date for such payment of interest.

(10) Amendments and Waivers. Subject to certain exceptions, (i) the Indenture or the Notes may be amended or supplemented with the consent of the Holders of a majority in principal amount of the Notes; and (ii) any existing default with respect to the Notes may be waived with the consent of the Holders of a majority in principal amount of the Notes. Without the consent of any Holder, the Indenture or the Notes may be amended or supplemented in accordance with Section 9.1 of the Base Indenture to, among other things, cure any ambiguity, mistake, omission, defect or inconsistency, to provide for the assumption of the Company’s obligations to Holders or to provide for uncertificated Notes or Notes registered under the Securities Act and offered in exchange for the Notes, to provide for guarantees with respect to, or security for, the Notes, or to comply with amendments to the TIA, or to add additional covenants, or to surrender any right or power conferred upon the Company, or to make any change that does not adversely affect the rights of any Holder of the Notes.

If an Event of Default with respect to the Notes occurs and is continuing, the Trustee or Holders of at least 25% in aggregate principal amount of the Notes may, by notice in writing to the Company (and the Trustee if given by the Holders), declare all the Notes to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security and/or indemnity satisfactory to it against the losses, costs, expenses, fees, and liabilities which might be incurred by it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the outstanding Notes may direct the Trustee in writing in its exercise of any trust or power with respect to the Notes. The Trustee may withhold from Holders notice of any Default or Event of Default (except a Default in payment of principal or interest) if it determines in good faith that withholding notice is in the Holders’ interests. The Company must furnish an annual compliance certificate to the Trustee.

(12) Trustee Dealings with Company. Subject to the provisions of the TIA, if applicable, the Trustee under the Indenture, 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 Trustee. The Trustee shall initially be Computershare Trust Company, National Association.

(13) No Recourse Against Others. A director, officer, incorporator or shareholder, as such, past, present or future, of the Company or any successor corporation of the Company or any of any Guarantor, shall not have any liability for any obligations of the Company or any Guarantor under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.
