“S&P” means Standard & Poor’s Ratings Services, and its successors.

“Secured Leverage Ratio” means, on any date, the ratio of (a) consolidated total Debt of the Company and its Consolidated Subsidiaries that is secured by a Lien on any assets or property of the Company or a Subsidiary outstanding on such date to (b) Consolidated EBITDA of the Company for the most recent four fiscal quarter period for which internal financial statements of the Company are available on such date, determined on a pro forma basis for any Debt incurred, repaid or otherwise retired on such date and, if applicable, the use or proceeds therefrom.

For purposes of making the computation referred to above, any Specified Transaction that has been made by the Company or any of its Subsidiaries during the relevant four quarter period or subsequent to such four quarter period and on or prior to or simultaneously with the calculation of the Secured Leverage Ratio shall be calculated on a pro forma basis assuming that all such Specified Transactions (and any increase or decrease in Consolidated EBITDA) had occurred on the first day of the applicable four quarter period. If since the beginning of the relevant four quarter period any Person that subsequently became a Subsidiary or was merged or consolidated with or into the Company or any of its Subsidiaries since the beginning of such period shall have made any Specified Transaction that would have required adjustment pursuant to this definition, then the Secured Leverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Specified Transaction had occurred at the beginning of the applicable period.

For purposes of this definition, whenever pro forma effect is to be given to any Specified Transaction, the pro forma calculations shall be made in good faith by a financial officer of the Company and may include, for the avoidance of doubt but without duplication of amounts included pursuant to the definition of “Consolidated EBITDA”, the amount of “run-rate” cost savings, synergies and operating expense reductions and synergies projected by the Company in good faith to be realized as a result of specified actions taken, committed to be taken or with respect to which substantial steps have been taken or are expected to be taken no later than 18 months after the date of any such Specified Transaction (in each case as though such cost savings, operating expense reductions and synergies had been realized on the first day of the applicable period and as if such cost savings, operating expense reductions and synergies were realized for the entirety of such period); provided that such cost savings, operating expense reductions and synergies are reasonably identifiable and factually supportable in the good faith judgment of the Company. For the purposes of the Indenture, “run-rate” means the full recurring benefit for a period that is associated with any action taken, committed to be taken, or with respect to which substantial steps have been taken or are expected to be taken, net of the amount of actual benefits realized during such period from such action during the relevant period.

“Specified Transaction” means (a) any designation of operations or assets of the Company or a Subsidiary as discontinued operations (as defined under GAAP), (b) any investment that results in a Person becoming a Subsidiary, (c) any acquisition of a business unit, line of business or division by the Company or any Subsidiary or (d) any asset sale that results in a Subsidiary ceasing to be a Subsidiary of the Company or any asset sale of a business unit, line of business or division of the Company or a Subsidiary, in each case whether by merger, consolidation, amalgamation or otherwise.

“Standard Receivables Undertakings” means representations, warranties, covenants and indemnities entered into by the Company or any Subsidiary of the Company which are customary in a Qualified Receivables Transaction, including, without limitation, those relating to the servicing of the assets of a Receivables Entity, it being understood that any Receivables Repurchase Obligation shall be deemed to be a Standard Receivables Undertaking.

“Treasury Rate” means the weekly average for each Business Day during the most recent week that has ended at least two Business Days prior to the Redemption Date (or, if the applicable redemption is in connection with a satisfaction and discharge of the Indenture with respect to the Notes pursuant to Section 4.01 hereof, prior to the date notice of such redemption is delivered to the Trustee) of the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the Federal Reserve Statistical Release H.15 (or, if such statistical release is not so published or available, any publicly available source of similar market data selected by the Company in good faith)) most nearly equal to the period from the Redemption Date to July 15, 2023; provided, however, that if the period from the Redemption Date to July 15, 2023 is not equal to the constant maturity of a United States Treasury security for which a yield is given, the applicable Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the yields of United States Treasury securities for which such yields are given, except that if the period from the Redemption Date to such applicable date is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

“Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the Capital Stock of such person that is at the time entitled to vote generally in the election of the Board of Directors of such person.

“Wholly Owned Domestic Subsidiary” of any Person means a direct or indirect Subsidiary of such Person organized under the laws of the United States, any state thereof or the District of Columbia, 100% of the outstanding Capital Stock or other ownership interests of which (other than directors’ qualifying shares or shares or interests required to be held by foreign nationals or other third parties to the extent required by applicable law) shall at the time be owned by such Person or by one or more Wholly Owned Domestic Subsidiaries of such Person.

Section 1.03 Rules of Construction. For all purposes of this Supplemental Indenture:

(a) capitalized terms used herein without definition shall have the meanings specified in the Base Indenture;

(b) all references herein to Articles and Sections, unless otherwise specified, refer to the corresponding Articles and Sections of this Supplemental Indenture;

The Notes will be initially issued in an aggregate principal amount of $400,000,000 (not including the Notes authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Securities pursuant to Sections 304, 305 or 306 of the Base Indenture); provided that the Company may, without the consent of Holders of the Notes, issue additional Notes having the same ranking and the same interest rate, maturity and other terms as the Notes, except for the issue date, issue price and payment of interest accruing prior to the issue date of the additional Notes), which additional Notes will constitute a single series of Securities under the Indenture.

Section 2.03 Maturity Date. The date on which the principal of the Notes is payable is July 15, 2028, subject to the provisions of the Indenture relating to acceleration.

Section 2.04 Ranking. The Notes will be senior and unsecured debt of the Company and will rank equally with all other existing and future unsecured and unsubordinated indebtedness of the Company.

The Notes will bear interest from July 24, 2020, or from the most recent interest payment date to which interest has been paid or duly provided for, at a rate of 6.375% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, commencing January 15, 2021. The Company will pay interest to the Person in whose name a Note is registered at the close of business on January 1 or July 1 next preceding the interest payment date. The Company will compute interest on the basis of a 360-day year consisting of twelve 30-day months. If any interest payment date or maturity date falls on a day that is not a Business Day, the required payment of interest or principal will be made on the next Business Day as if made on the date that payment was due, and no interest will accrue on that payment for the period from and after the interest payment date or maturity date, as the case may be, to the date of the payment on the next Business Day.

Section 2.06 Place of Payment for Principal and Interest.

Section 2.07 Issuance Price. The purchase price to be paid to the Company for the sale of the Notes pursuant to the terms of the Underwriting Agreement, dated as of July 10, 2020, between the Company and BofA Securities, Inc., as representative of the several Underwriters listed on Schedule I thereto, shall be 98.875% of the principal amount of the Notes, reflecting the initial offering price to the public of the Notes of 100.000% of the principal amount of the Notes and the underwriting discount of 1.125% of the principal amount of the Notes.

Section 2.08 Defeasance. The Notes shall be subject to legal defeasance under Section 1302 of the Base Indenture and to covenant defeasance under Section 1303 of the Base Indenture as permitted pursuant to Section 1301 of the Base Indenture.

(b) The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Supplemental Indenture, and the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Notes conflicts with the express provisions of this Supplemental Indenture, the provisions of this Supplemental Indenture shall govern and be controlling.

(c) The Notes will be issued in the form of a fully-registered global security (the “Global Security”). The Depository Trust Company shall serve as the depository (the “Depositary”) for the Global Security. The Global Security will be deposited with, or on behalf of, the Depositary and registered, at the request of the Depositary, in the name of Cede &Co. Except as set forth below, the Global Security may be transferred, in whole and not in part, only by the Depositary to its nominee or by its nominee to such Depositary or another nominee of the Depositary or by the Depositary or its nominee to a successor of the Depositary or a nominee of such successor. If (i) the Depositary is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 calendar days after receipt of such notice from the Depositary; (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act and the Company does not appoint a successor depositary within 90 calendar days of becoming aware that the Depositary has ceased to be registered as a clearing agency; (iii) the Company, in their sole discretion, determines that the Notes will be exchangeable for definitive securities in registered form and notify the Trustee of their decision; or (iv) an Event of Default with respect to the Notes represented by the Global Security has occurred and is continuing, then in each case the Company may issue Notes in certificated form in exchange for the Global Security. In each of these instances, an owner of an interest in the Global Security would be entitled to physical delivery of such Notes in certificated form. Notes so issued in certificated form will be issued in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof and will be issued in registered form only.

(c) Notwithstanding the foregoing, at any time and from time to time prior to July 15, 2023, upon notice as described in clause (g) below, the Company may redeem in the aggregate up to 40% of the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional Notes of the same series as the Notes offered hereby) with an amount not to exceed the net cash proceeds of one or more Equity Offerings, at a redemption price (expressed as a percentage of the principal amount thereof) equal to 106.375%, plus accrued and unpaid interest, if any, to (but not including) the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling prior to or on the Redemption Date); provided, however, that at least 60% of the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional Notes of the same series as the Notes offered hereby) must remain outstanding after each such redemption; provided that such redemption shall occur within 120 days after the date on which such Equity Offering is consummated.

(d) If Holders of not less than 90% in aggregate principal amount of the then outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any other Person making a Change of Control Offer in lieu of the Company as described in Section 2.12, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company will have the right, upon notice as described in clause (g) below, 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 the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest to but excluding the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

In addition, if such redemption or notice is subject to satisfaction of one or 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, as solely determined by the Company (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be modified or rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Company in the Company’s sole discretion) by the Redemption Date, or by the Redemption Date so delayed. In addition, such notice of redemption may be extended if such conditions precedent have not been met by providing notice to the Holders.

(f) In addition to any redemption pursuant to this Section 2.11, the Company or its affiliates may at any time and from time to time purchase Notes. Any such purchases may be made through open market or privately negotiated transactions with third parties or pursuant to one or more tender or exchange offers or otherwise, upon such terms and at such prices as well as with such consideration as the Company or any such affiliates may determine.

(g) Notices of redemption will be delivered at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address or otherwise in accordance with the procedures of DTC, except that redemption notices may be delivered more than 60 days prior to the Redemption Date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the Indenture.

(h) Other than as specifically provided in this Section 2.11 and Section 2.13, any redemption pursuant to this Section 2.11 shall be made pursuant to the provisions of Article Eleven of the Base Indenture.

Section 2.12 Change of Control Repurchase Event.

(a) If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes as described in Section 2.11, the Company shall be required to make an offer (the “Change of Control Offer”) to each Holder of the Notes to repurchase, all or any part (in a minimum denomination of $2,000 and in integral 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 repurchased, plus any accrued and unpaid interest on such Notes repurchase to, but not including, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of a transaction or transactions that constitute or may constitute a Change of Control, the Company shall mail a notice to each Holder of 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 to repurchase the Notes on the payment 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 other than as required by law. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

(b) On or before the repurchase date following a Change of Control Repurchase Event, the Company shall, to the extent lawful:

(i) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the Company’s offer;

(ii) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all 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 Officers’ Certificate stating the aggregate principal amount of the Notes being repurchased.

(c) 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 the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with this Section 2.12, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 2.12.

(d) The paying agent will promptly deliver each Holder of Notes properly tendered, the purchase price for the Notes, and the Trustee will 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; provided that each new Note will be in a minimum denomination of $2,000 and in integral multiples of $1,000.

(e) The Company shall not be required to comply with the obligations of this Section 2.12 if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all notes properly tendered and not withdrawn under its offer (it being understood that such third party may make an offer that is conditioned on and prior to the occurrence of a Change of Control). The Company shall not be required to make an offer to repurchase the notes upon a Change of Control Repurchase Event if notice of redemption has been given pursuant to the indenture as described under the caption Section 2.11 unless there is a default in the payment of the applicable Redemption Price.

(f) Other than as specifically provided in this Section 2.12 and Section 2.13, any purchase pursuant to this Section 2.12 shall be made pursuant to the provisions of Article Eleven of the Base Indenture.

Section 2.13 Selection of Notes to be Redeemed. The provisions of the first paragraph of Section 1103 of the Base Indenture shall not apply to the Notes, and the following provisions shall apply in lieu thereof: In the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements and the procedures of the Depository Trust Company (“DTC”)) in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof; provided that the selection of Notes for redemption shall not result in a Holder of Notes with a principal amount of Notes less than the minimum denomination. If any Note is to be purchased or redeemed in part only, the notice of purchase or redemption relating to such Note shall state the portion of the principal amount thereof that has been or is to be purchased or redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note.

Section 2.14 Execution and Authentication of Notes. The Notes shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents and attested by its Treasurer, one of its Assistant Treasurers, its Secretary, or one of its Assistant Secretaries. The signature of any of these officers on the Notes may be manual or facsimile. At any time and from time to time after the execution and delivery of this Supplemental Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with an order for the authentication and delivery of such Notes, and the Trustee in accordance with such order shall authenticate and deliver such Notes. Such order may be signed by the Company’s Treasurer, one of its Assistant Treasurers, its Secretary, or one of its Assistant Secretaries.

ARTICLE III

COVENANTS

Section 3.01 Restrictions on Secured Debt. The provisions of Section 1008 of the Base Indenture shall not apply to the Notes, and the following provisions shall apply in lieu thereof: If the Company or any Subsidiary shall incur, issue, assume or guarantee any indebtedness for money borrowed (“Debt”) secured by a mortgage, pledge or lien (“Lien”) on any assets or property of the Company or any Subsidiary (other than Permitted Liens), the Company will provide or cause such Subsidiary to provide that the Notes (together with, if the Company shall so determine, any other Debt of the Company or its Subsidiaries then existing or thereafter created which is not subordinated to the Notes) be secured equally and ratably with (or, at the Company’s option, prior to) such secured Debt for so long as such other Debt is so secured by such Lien.

For purposes of determining compliance with this covenant, (a) a Lien securing an item of Debt need not be permitted solely by reference to one category of permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” but may be permitted in part under any combination thereof and (b) in the event that a Lien securing an item of Debt (or any portion thereof) meets the criteria of one or more of the categories of permitted Liens (or any portion thereof) described in the definition of “Permitted Liens,” the Company may, in its sole discretion, classify or reclassify, or later divide, classify or reclassify, such Lien securing such item of Debt (or any portion thereof) in any manner that complies with this covenant.

In addition, for purposes of determining compliance with this covenant, the Company may elect, pursuant to an officers’ certificate delivered to the Trustee, to treat all or any portion of the commitment under any Debt (and any refinancing with respect thereto) (any such commitment, a “Designated Commitment”) as being incurred at such time and being secured by a Lien at such time, in which case (a) any subsequent incurrence of Debt under such commitment or refinancing or incurrence of Liens to secure such Debt, as the case may be, shall not be deemed, for purposes of this calculation, to be an incurrence at such subsequent time and (b) without duplication, Debt in an amount equal to the amount of such commitment shall be deemed to be outstanding (whether or not such commitment is funded) until such commitment is terminated.

With respect to any Lien securing Debt that was permitted to secure such Debt at the time of the incurrence of such Debt, such Lien shall also be permitted to secure any Increased Amount of such Debt. The “Increased Amount” of any Debt shall mean any increase in the amount of such Debt in connection with any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Debt with the same terms or in the form of common stock of the Company, the payment of dividends on preferred stock in the form of additional shares of preferred stock of the same class, accretion of original issue discount or liquidation preference and increases in the amount of Debt outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Debt.

Section 3.02 Restrictions on Sales and Leasebacks. The provisions of Section 1009 of the Base Indenture shall not apply to the Notes, and the following provisions shall apply in lieu thereof: Neither the Company nor any of its Subsidiaries will enter into any sale and leaseback transaction involving any of its respective assets or properties, unless, after giving effect thereto, the aggregate amount of all Attributable Debt with respect to such transactions would be permitted to be secured by Permitted Liens assuming such Attributable Debt was “Debt” for all purposes (including the definition of “Secured Leverage Ratio”) of Section 3.01 hereof.

The above restrictions will not apply to, and there will be excluded from Attributable Debt in any computation under such restriction, any sale and leaseback transaction if (i) the lease is for a period, including renewal rights, of not in excess of three years, (ii) the sale and leaseback transaction of the property is made prior to, at the time of or within 180 days after its acquisition or completion of construction, (iii) the lease secures or relates to industrial revenue or pollution control bonds, (iv) the transaction is between the Company and a Subsidiary or between any Subsidiaries, (v) the Company or such Subsidiary within 180 days after the sale or transfer applies an amount equal to the greater of the net proceeds of the sale of the property leased pursuant to such arrangement or the fair market value of the property so leased at the time of entering into such arrangement to (a) the retirement of the Notes or Funded Debt of the Company ranking on a parity to the Notes or Funded Debt of a Subsidiary or (b) the purchase of other property having a fair market value, in the opinion of the Board of Directors of the Company, at least equal to the fair market value of the property so leased. The amount to be applied to the retirement of such Funded Debt of the Company or a Subsidiary shall be reduced by (x) the principal amount of any Notes (or other notes or debentures constituting such Funded Debt) delivered within such 180-day period to the Trustee or other applicable trustee for retirement and cancellation and (y) the principal amount of such Funded Debt other than items referred to in the preceding clause (x), voluntarily retired by the Company or a Subsidiary within 180 days after such sale, provided that, notwithstanding the foregoing, no retirement referred to in this paragraph may be effected by payment at maturity or pursuant to any mandatory sinking fund payment or any mandatory prepayment provision.

ARTICLE IV

MISCELLANEOUS PROVISIONS

Section 4.01 Satisfaction and Discharge of the Indenture. The Indenture will be discharged and will cease to be of further effect as to all outstanding Notes when:

(a) either (1) all the Notes theretofore authenticated and delivered (except lost, stolen, mutilated or destroyed Notes which have been replaced or paid and Notes for whose payment money or certain United States government obligations have theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation or (2) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable or will become due and payable at their maturity date within one year, or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the serving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit (in the case of Notes which have become due and payable) or to the maturity date or Redemption Date, as the case may be, together with instructions from the Company irrevocably directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

6.375% Senior Notes Due 2028

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an indenture, dated as of January 12, 1994, as supplemented by the Fourth Supplemental Indenture, dated July 24, 2020 (as so supplemented, the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

On and after July 15, 2023, the Company may redeem the Notes issued under the Indenture, at its option, in whole at any time or in part from time to time, upon notice as described below at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest, if any, to (but not including) the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling prior to or on the Redemption Date), if redeemed during the 12-month period commencing on July 15 of the years set forth below:

Period	Redemption Price
2023		103.188	%
2024		101.594	%
2025 and thereafter		100.000	%

At any time prior to July 15, 2023, the Company may redeem the Notes issued under the Indenture, at its option, in whole at any time or in part from time to time, upon notice as described below at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium, and accrued and unpaid interest, if any, to (but not including) the applicable Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling prior to or on the Redemption Date).

Notwithstanding the foregoing, at any time and from time to time prior to July 15, 2023, upon notice as described below, the Company may redeem in the aggregate up to 40% of the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional Notes of the same series as the Notes offered hereby) with an amount not to exceed the net cash proceeds of one or more Equity Offerings, at a redemption price (expressed as a percentage of the principal amount thereof) equal to 106.375%, plus accrued and unpaid interest, if any, to (but not including) the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling prior to or on the Redemption Date); provided, however, that at least 60% of the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional Notes of the same series as the Notes offered hereby) must remain outstanding after each such redemption; provided that such redemption shall occur within 120 days after the date on which such Equity Offering is consummated.

In connection with any redemption of the Notes (including with the net cash proceeds of an Equity Offering), any such redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, consummation of any related Equity Offering or consummation of a Change of Control Repurchase Event. In addition, if such redemption or notice is subject to satisfaction of one or 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, as solely determined by the Company (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be modified or rescinded in the event that any or all 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. In addition, such notice of redemption may be extended if such conditions precedent have not been met by providing notice to the Holders.

A-6

The Company or its affiliates may at any time and from time to time purchase Notes. Any such purchases may be made through open market or privately negotiated transactions with third parties or pursuant to one or more tender or exchange offers or otherwise, upon such terms and at such prices as well as with such consideration as the Company or any such affiliates may determine.

Notices of redemption will be delivered at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address or otherwise in accordance with the procedures of DTC, except that redemption notices may be delivered more than 60 days prior to the Redemption Date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the Indenture.

Other than as specifically provided herein, any redemption pursuant to the provisions above shall be made pursuant to the provisions of Article Eleven of the Indenture.

In the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements and the procedures of the Depository Trust Company (“DTC”)) in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof; provided that the selection of Notes for redemption shall not result in a Holder of Notes with a principal amount of Notes less than the minimum denomination. If any Note is to be purchased or redeemed in part only, the notice of purchase or redemption relating to such Note shall state the portion of the principal amount thereof that has been or is to be purchased or redeemed. A new note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

A-7

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall affect or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof.
