constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date the notice is mailed (the “Change of Control Payment Date”). The notice will, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date and that, at the Company’s discretion, the Change of Control Payment Date may be delayed until such time as the Change of Control shall occur, or that such repurchase may not occur and such notice may be rescinded in the event that the Company shall determine that such condition will not be satisfied by the Change of Control Payment Date (without prejudice to the Company’s obligation to make a Change of Control Offer if in fact a Change of Control Triggering Event subsequently occurs).

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

(ii)deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(d)Notwithstanding the above, the Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer to be made by the Company and the third party repurchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any Notes 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.

(e)The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the Company’s repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

(f)If Holders of not less than 90% in aggregate principal amount of the outstanding Notes of a particular series properly 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 as described in Section 2.10(d), purchases all of the Notes of such series properly tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer described in this Section 2.10, to redeem all Notes of the applicable series that remain outstanding following such purchase at a price in cash equal to 101% of the aggregate principal amount of such Notes being redeemed, plus accrued and unpaid interest, if any, on such Notes to, but not including, the date of redemption.

Attest_________________________

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

This Security is one of a duly authorized issue of Securities of the Company designated as its 1.950% Notes due July 15, 2019 (Securities of such series being hereinafter called the “Securities”), limited in aggregate principal amount to $[ ], issued under an Indenture dated as of November 1, 2001, as supplemented by the First Supplemental Indenture dated as of December 4, 2006 and the Second Supplemental Indenture dated as of April 10, 2017 (hereinafter called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as Trustee (hereinafter called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the Securities of this series), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and any Holder of the Securities, and the terms upon which the Securities are, and are to be, authenticated and delivered.

Except as set forth below, this Security will be issued in global form only registered in the name of the Depositary or its nominee. Except as set forth below, this Security will not be issued in definitive form and ownership of this Security shall be maintained in book-entry form by the Depositary for the accounts of participating organizations of the Depositary.

The Depositary for the Securities shall initially be The Depositary Trust Company. If the Depositary is at any time unwilling, unable or ineligible to continue as Depositary for the Securities and the Company does not appoint a successor Depositary within 90 days, the Company will issue Securities in definitive form to participants of the Depositary in exchange for the Global Security representing the Securities. In addition, the Company may, at any time and in its sole discretion, determine not to have any Securities represented in global form. In that event, the Company will issue Securities in definitive form to participants of the Depositary in exchange for the Global Security.

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

This Security is not entitled to the benefit of a sinking fund or any analogous provision. Securities will be redeemable as a whole at any time or in part from time to time prior to maturity, at the option of the Company, on not less than 30 or more than 60 days' notice mailed to Holders thereof, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities being redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments (as defined below) of the Securities being redeemed (excluding interest accrued as of the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of

twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points, together, in each case, with accrued and unpaid interest on the principal amount being redeemed to but not including the Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker and having an actual or interpolated Maturity comparable to the remaining term of the Securities to be redeemed (assuming, for this purpose, that the Securities matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable Maturity to the remaining term of the Securities.

“Comparable Treasury Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers selected by the Company or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

“Reference Treasury Dealer” means (i) J.P. Morgan Securities LLC, Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, or their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company shall substitute another Primary Treasury Dealer and (ii) any other Primary Treasury Dealers selected by the Company after consultation with the Independent Investment Banker.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date but for such redemption.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

The Treasury Rate will be calculated by the Independent Investment Banker on the third Business Day preceding the Redemption Date.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or any portion thereof called for redemption. On or before any Redemption Date, the Company shall deposit with a Paying Agent (or the Trustee) money sufficient to pay the Redemption Price of and accrued interest on the Securities to be redeemed on such date. If less than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed by any method the Trustee shall deem fair and appropriate.

If a Change of Control Triggering Event occurs, unless the Company has exercised its option to redeem the Securities as described above, the Company will be required to make an offer (the “Change of Control Offer”) to each Holder of the Securities to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder's Securities on the terms set forth herein. In the Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of the Securities repurchased, plus accrued and unpaid interest, if any, on the Securities repurchased to, but not including, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company's option, prior to the date of the consummation of any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Company will be required to deliver a notice to Holders of Securities, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Securities on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”) pursuant to the procedures described in such notice.

The notice shall, if sent prior to the date of the consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date and that, at the Company’s discretion, the Change of Control Payment Date may be delayed until such time as the Change of Control shall occur, or that such repurchase may not occur and such notice may be rescinded in the event that the Company shall determine that such condition will not be satisfied by the Change of Control Payment Date (without prejudice to the Company’s obligation to make a Change of Control Offer if in fact a Change of Control Triggering Event subsequently occurs).

On the Change of Control Payment Date, the Company will be required, to the extent lawful: (i) accept for payment all Securities or portions of Securities properly tendered pursuant to the Change of Control Offer; (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly tendered; and (iii) deliver or cause to be delivered to the Trustee for cancellation the Securities properly accepted together with an Officers' Certificate stating the aggregate principal amount of Securities or portions of Securities being repurchased.

The Paying Agent will promptly mail or electronically deliver to each Holder of Securities properly tendered the Change of Control Payment for the Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Security equal in principal amount to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

Notwithstanding the above, the Company will not be required to make the Change of Control Offer upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer to be made by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any 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

If Holders of not less than 90% in aggregate principal amount of the outstanding Securities properly tender and do not withdraw such Securities in a Change of Control Offer and we, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Securities properly tendered and not withdrawn by such Holders, we or such third party will have the right, upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Securities that remain outstanding following such purchase on a date (the “second change of control payment date”) at a price in cash equal to the applicable Change of Control payment in respect of the second change of control payment date.

The Company will 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 to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the Securities, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Indenture or the Change of Control Offer provisions of the Securities by virtue of any such conflicts.

“Change of Control” means the occurrence of any of the following: (1) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) (other than the Company or one of its subsidiaries) becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company’s Voting Stock or other Voting Stock into which the Company's Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; or (2) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more series of

related transactions, of all or substantially all of the Company’s and its subsidiaries’ properties and assets, taken as a whole, to one or more Persons (other than the Company or one of its subsidiaries). Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (1) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company's Voting Stock immediately prior to that transaction or (B) immediately following that transaction no Person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event.

“Fitch” means Fitch Ratings, Inc. and its successors.

“Investment Grade Rating” means a rating equal to or higher than BBB- (or the equivalent) by Fitch, Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the Company.

“Moody’s” means Moody’s Investors Service Inc. and its successors.

“Rating Agencies” means (1) each of Fitch, Moody’s and S&P; and (2) if any of Fitch, Moody’s or S&P ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside of the Company's control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Fitch, Moody’s or S&P, or any of them, as the case may be.

“Rating Event” means the rating on the Notes is lowered by each of the Rating Agencies and the Notes are rated below an Investment Grade Rating by each of the Rating Agencies on any day within the 60-day period (which 60-day period will be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies, such extension to last with respect to each such Rating Agency until the date on which such Rating Agency considering such possible downgrade either (x) rates the applicable series of Notes below an Investment Grade Rating or (y) publicly announces that it is no longer considering such Notes for possible downgrade, provided that no such extension shall occur if on such 60th day the applicable series of Notes is rated with an Investment Grade Rating by at least one of such Rating Agencies in question and is not subject to review for possible downgrade by such Rating Agency) after the earlier of (1) the occurrence of a Change of Control and (2) public notice of (i) the occurrence of a Change of Control or (ii) an arrangement that could result in the occurrence of a Change of Control; provided, however, that a Rating Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a

Rating Event for purposes of the definition of Change of Control Triggering Event hereunder) if any Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s or its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the Rating Event).

“S&P” means S&P Global Ratings, a division of S&P Global, Inc., and its successors.

“Voting Stock” means, with respect to any specified person as of any date, the capital stock of such person then outstanding that is at the time entitled to vote generally in the election of the board of directors or similar governing body of such person.

The Company may from time to time, without notice to or the consent of the Holders, create and issue further notes ranking equally and ratably with the Securities in all respects (or in all respects except for the payment of interest accruing prior to the issue date of such further notes or except for the first payment of interest following the issue date of such further notes), so that these further notes will be consolidated and form a single series with the Securities and have the same terms as to status, redemption or otherwise as the Securities, provided that if such further notes are not fungible for United States federal income tax purposes, the further notes will have a separate CUSIP number.

As provided in the Indenture and subject to certain limitations therein set forth, this Security may be registered for transfer on the Security Register of the Company, upon surrender of this Security for registration of transfer at the office or agency of the Company in the Place of Payment, and at such other locations as the Company may from time to time designate, 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 the Holder's attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities are issuable only as Registered Securities without coupons in the denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of different authorized denominations, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment for registration of transfer of this Security, the Company, the Trustee, the Security Registrar, the Paying Agent and any agent of any one thereof may treat the Person in whose name this Security is registered as the owner hereof for all

purposes, whether or not this Security be overdue, and neither the Company, the Trustee, the Security Registrar, the Paying Agent nor any such agent shall be affected by notice to the contrary.

If an Event of Default with respect to the Securities shall occur, the principal of all the Securities 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 with respect to the Securities and the rights of the Holders of the Securities under the Indenture at any time by the Company with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, 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 a notation of such consent or waiver is made upon this Security.

No recourse shall be had for the payment of the principal of or the interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

The Company at its option, subject to the terms and conditions contained in the Indenture, (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations to register the transfer and exchange of such Securities, to replace mutilated, destroyed, lost or stolen Securities, to compensate, reimburse and indemnify the Trustee, to maintain an office or agency with respect to the Securities and to hold moneys for payment in trust) or (b) may omit to comply with certain restrictive covenants contained in the Indenture, in each case upon irrevocable deposit with the Trustee in trust of money or U.S. government securities (as described in the Indenture) or a combination thereof, which through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to discharge the principal of and interest on such Securities on the Stated Maturity of such principal or interest.

Except as otherwise defined herein, all terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The Company will 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 to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the Securities, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Indenture or the Change of Control Offer provisions of the Securities by virtue of any such conflicts.

Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 20 basis points, together, in each case, with accrued and unpaid interest on the principal amount being redeemed to but not including the Redemption Date. Securities will be redeemable as a whole at any time or in part from time to time on or after the Par Call Date, at the option of the Company, on not less than 30 or more than 60 days’ notice mailed to Holders thereof, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed, with accrued and unpaid interest on the principal amount being redeemed to but not including the Redemption Date.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date but for such redemption.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate will be calculated by the Independent Investment Banker on the third Business Day preceding the Redemption Date.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or any portion thereof called for redemption. On or before any Redemption Date, the Company shall deposit with a Paying Agent (or the Trustee) money sufficient to pay the Redemption Price of and accrued interest on the Securities to be redeemed on such date.

If funds sufficient to pay the special acquisition redemption price of all Securities to be redeemed on the Special Acquisition Redemption Date are deposited with the Trustee on or before such Special Acquisition Redemption Date, plus accrued and unpaid interest, if any, to but excluding the Special Acquisition Redemption Date, such Securities will cease to bear interest and all rights under such Securities shall terminate (other than in respect of the right to receive the special acquisition redemption price, plus accrued and unpaid interest to but excluding the Special Acquisition Redemption Date).

Attest_________________________

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

This Security is one of a duly authorized issue of Securities of the Company designated as its 4.350% Notes due April 15, 2047 (Securities of such series being hereinafter called the “Securities”), limited in aggregate principal amount to $[ ], issued under an Indenture dated as of November 1, 2001, as supplemented by the First Supplemental Indenture dated as of December 4, 2006 and the Second Supplemental Indenture dated as of April 10, 2017 (hereinafter called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as Trustee (hereinafter called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the Securities of this series), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and any Holder of the Securities, and the terms upon which the Securities are, and are to be, authenticated and delivered.

Except as set forth below, this Security will be issued in global form only registered in the name of the Depositary or its nominee. Except as set forth below, this Security will not be issued in definitive form and ownership of this Security shall be maintained in book-entry form by the Depositary for the accounts of participating organizations of the Depositary.

The Depositary for the Securities shall initially be The Depositary Trust Company. If the Depositary is at any time unwilling, unable or ineligible to continue as Depositary for the Securities and the Company does not appoint a successor Depositary within 90 days, the Company will issue Securities in definitive form to participants of the Depositary in exchange for the Global Security representing the Securities. In addition, the Company may, at any time and in its sole discretion, determine not to have any Securities represented in global form. In that event, the Company will issue Securities in definitive form to participants of the Depositary in exchange for the Global Security.

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

This Security is not entitled to the benefit of a sinking fund or any analogous provision. Securities will be redeemable as a whole at any time or in part from time to time prior to the Par Call Date (as defined below), at the option of the Company, on not less than 30 or more than 60 days' notice mailed to Holders thereof, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities being redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments (as defined below) of the Securities being redeemed assuming for such purpose that the Securities matured on the Par Call Date (excluding interest accrued as of the Redemption

Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 25 basis points, together, in each case, with accrued and unpaid interest on the principal amount being redeemed to but not including the Redemption Date. Securities will be redeemable as a whole at any time or in part from time to time on or after the Par Call Date, at the option of the Company, on not less than 30 or more than 60 days’ notice mailed to Holders thereof, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed, with accrued and unpaid interest on the principal amount being redeemed to but not including the Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker and having an actual or interpolated Maturity comparable to the remaining term of the Securities to be redeemed (assuming, for this purpose, that the Securities matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable Maturity to the remaining term of the Securities.

“Comparable Treasury Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers selected by the Company or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

“Par Call Date” means October 15, 2046 (six months prior to the maturity date of the Securities).

“Reference Treasury Dealer” means (i) J.P. Morgan Securities LLC, Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, or their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company shall substitute another Primary Treasury Dealer and (ii) any other Primary Treasury Dealers selected by the Company after consultation with the Independent Investment Banker.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date but for such redemption.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate will be calculated by the Independent Investment Banker on the third Business Day preceding the Redemption Date.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or any portion thereof called for redemption. On or before any Redemption Date, the Company shall deposit with a Paying Agent (or the Trustee) money sufficient to pay the Redemption Price of and accrued interest on the Securities to be redeemed on such date. If less than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed by any method the Trustee shall deem fair and appropriate.

The Company will be required to redeem all of the outstanding Securities at a redemption price equal to 101% of the aggregate principal amount of the Securities to be redeemed, plus accrued and unpaid interest to but excluding the Special Acquisition Redemption Date , if: (i) the Company terminates or abandons the B/E Aerospace Acquisition before 5:00 p.m. (New York City time) on October 21, 2017; or (ii) the B/E Merger Agreement is terminated at any time before 5:00 p.m. (New York City time) on October 21, 2017.

If the Company is required to redeem the Securities pursuant to the special acquisition redemption, the Company will cause the notice of special acquisition redemption to be delivered to each registered Holder of such Securities, with a copy to the Trustee, within five business days after the occurrence of the event that requires the Company to redeem. If funds sufficient to pay the special acquisition redemption price of all Securities to be redeemed on the Special Acquisition Redemption Date are deposited with the Trustee on or before such Special Acquisition Redemption Date, plus accrued and unpaid interest, if any, to but excluding the Special Acquisition Redemption Date, such Securities will cease to bear interest and all rights under such Securities shall terminate (other than in respect of the right to receive the special acquisition redemption price, plus accrued and unpaid interest to but excluding the Special Acquisition Redemption Date).

If a Change of Control Triggering Event occurs, unless the Company has exercised its option to redeem the Securities as described above, the Company will be required to make an offer (the “Change of Control Offer”) to each Holder of the Securities to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder's Securities on the terms set forth herein. In the Change

of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of the Securities repurchased, plus accrued and unpaid interest, if any, on the Securities repurchased to, but not including, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company's option, prior to the date of the consummation of any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Company will be required to deliver a notice to Holders of Securities, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Securities on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”) pursuant to the procedures described in such notice.

The notice shall, if sent prior to the date of the consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date and that, at the Company’s discretion, the Change of Control Payment Date may be delayed until such time as the Change of Control shall occur, or that such repurchase may not occur and such notice may be rescinded in the event that the Company shall determine that such condition will not be satisfied by the Change of Control Payment Date (without prejudice to the Company’s obligation to make a Change of Control Offer if in fact a Change of Control Triggering Event subsequently occurs).

On the Change of Control Payment Date, the Company will be required, to the extent lawful: (i) accept for payment all Securities or portions of Securities properly tendered pursuant to the Change of Control Offer; (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly tendered; and (iii) deliver or cause to be delivered to the Trustee for cancellation the Securities properly accepted together with an Officers' Certificate stating the aggregate principal amount of Securities or portions of Securities being repurchased.

The Paying Agent will promptly mail or electronically deliver to each Holder of Securities properly tendered the Change of Control Payment for the Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Security equal in principal amount to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

Notwithstanding the above, the Company will not be required to make the Change of Control Offer upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer to be made by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any 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

If Holders of not less than 90% in aggregate principal amount of the outstanding Securities properly tender and do not withdraw such Securities in a Change of Control Offer and we, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Securities properly tendered and not withdrawn by such Holders, we or such third party will have the right, upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Securities that remain outstanding following such purchase on a date (the “second change of control payment date”) at a price in cash equal to the applicable Change of Control payment in respect of the second change of control payment date.

The Company will 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 to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the Securities, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Indenture or the Change of Control Offer provisions of the Securities by virtue of any such conflicts.

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (1) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company's Voting Stock immediately prior to that transaction or (B) immediately following that transaction no Person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.
