the remaining term of the Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, the
Reference Treasury Dealer Quotations for that Redemption Date.

 “Reference Treasury Dealer Quotations” means, with respect to the Reference
Treasury Dealer and any Redemption Date, the average, as determined by an independent investment bank appointed by the Company, 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 Trustee by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding that Redemption Date. 

“Remaining Scheduled Payments” means the remaining scheduled payments of principal of and interest on the Notes that would be

 “Restricted Property” means (a) any manufacturing facility, or portion
thereof, owned or leased by the Company or any Subsidiary and located within the continental United States, which, in the opinion of the Board of Directors, is of material importance to the business of the Company and its Subsidiaries taken as a
whole, but no such manufacturing facility, or portion thereof, shall be deemed of material importance if its gross book value (before deducting accumulated depreciation) is less than 2% of Consolidated Tangible Net Assets, or (b) any shares of

yield to Maturity (computed as of the third Business Day immediately preceding that Redemption Date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to
the Comparable Treasury Price for that Redemption Date.

Transaction, an amount equal to the present value of the lease payments with respect to the term of the lease remaining on the date as of which the amount is being determined, without regard to any renewal or extension options contained in the
lease, discounted at the weighted average interest rate on the Notes which are outstanding on the effective date of such Sale and Leaseback Transaction and which have the benefit of Section 5.02 of this First Supplemental Indenture.

ADDITIONAL COVENANTS 

Section 5.01. Limitation on Liens. The Company shall not create, assume or suffer to exist any Lien upon Restricted Property to
secure any Indebtedness of the Company, any Subsidiary or any other Person, or permit any Subsidiary so to do, without making effective provision whereby the Notes then outstanding and having the benefit of this Section 5.01 shall be secured by
the Lien equally and ratably with such Indebtedness for so long as such Indebtedness shall be so secured, except that the foregoing shall not prevent the Company or any Subsidiary from creating, assuming or suffering to exist Liens of the following
character: 
 (1) any Lien existing on the date hereof; 

(2) any Lien existing on property owned or leased by a Corporation at the time it becomes a Subsidiary; 

(3) any Lien existing on property at the time of the acquisition thereof by the Company or a Subsidiary; 

(4) any Lien to secure any Indebtedness incurred prior to, at the time of, or within 12 months after the acquisition of Restricted
Property for the purpose of financing all or any part of the purchase price thereof and any Lien to the extent that it secures Indebtedness which is in excess of such purchase price and for the payment of which recourse may be had only against such
Restricted Property; 
  

 6 








 (5) any Lien to secure any Indebtedness incurred prior to, at the time of, or within 12
months after the completion of the construction and commencement of commercial operation, alteration, repair or improvement of Restricted Property for the purpose of financing all or any part of the cost thereof and any Lien to the extent that it
secures Indebtedness which is in excess of such cost and for the payment of which recourse may be had only against such Restricted Property; 

(6) any Lien securing Indebtedness of a Subsidiary owing to the Company or to another Subsidiary; 

(7) any Lien in favor of the United States or any state thereof or any other country, or any agency, instrumentality or political
subdivision or any of the foregoing, to secure partial, progress, advance or other payments or performance pursuant to the provisions of any contract or statute, or any Liens securing industrial development, pollution control, or similar revenue
bonds; 
 (8) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part of
any Lien referred to in clauses (1) through (7) above, so long as the principal amount of the Indebtedness secured thereby does not exceed the principal amount of Indebtedness so secured at the time of the extension, renewal or replacement
(except that, where an additional principal amount of Indebtedness is incurred to provide funds for the completion of a specific project, the additional principal amount, and any related financing costs, may be secured by the Lien as well) and the
Lien is limited to the same property subject to the Lien so extended, renewed or replaced (plus improvements on the property); and 

(9) any Lien not permitted by clauses (1) through (8) above securing Indebtedness which, together with the aggregate
outstanding principal amount of all other Indebtedness of the Company and its Subsidiaries owning Restricted Property which would otherwise be subject to the foregoing restrictions and the aggregate Value of existing Sale and Leaseback Transactions
which would be subject to the restrictions of Section 5.02 of this First Supplemental Indenture but for this clause (9), does not at any time exceed 10% of Consolidated Tangible Net Assets. 

Section 5.02. Limitation on Sale and Leasebacks. The Company shall not enter into any Sale and Leaseback Transaction, nor permit
any Subsidiary owning Restricted Property so to do, unless either: 
 (1) the Company or such Subsidiary would be entitled to
incur Indebtedness, in a principal amount at least equal to the Value of such Sale and Leaseback Transaction, which is secured by Liens on the property to be leased (without equally and ratably securing the outstanding Notes having the benefit of
Section 5.01 of this First Supplemental Indenture) because such Liens would be 
  

 7 








 
of such character that no violation of any of the provisions of Section 5.01 of this First Supplemental Indenture would result, or 

(2) the Company during the six months immediately following the effective date of such Sale and Leaseback Transaction causes to be
applied to (A) the acquisition of Restricted Property or (B) the voluntary retirement of Funded Debt (whether by redemption, defeasance, repurchase, or otherwise) an amount equal to the lesser of (i) the net proceeds of the sale of
the Restricted Property leased pursuant to such Sale and Leaseback Transaction or the fair value of the Restricted Property so leased (whichever amount is greater) or (ii) the Value of such Sale and Leaseback Transaction. 

Section 5.03. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this First Supplemental Indenture. 

Section 5.04. Maintenance of Properties. The Company will cause all properties used or useful in the conduct of its business or
the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 5.04 shall
prevent the Company from discontinuing the operation or maintenance or both of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary and not
adverse in any material respect to the Holders. 
 Section 5.05. Payment of Taxes and Other Claims. The Company will or
will cause a Subsidiary to pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary, and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings or if the Company shall
determine that the payment thereof is not desirable in the conduct of its business or the business of any subsidiary and that the nonpayment thereof is not disadvantageous in any material respect to the Holders. 

 

 8 








 Section 5.06. Waiver of Covenants. The Company may omit in any particular instance to
comply with any covenant or condition set forth in Sections 5.01, 5.02, 5.04, 5.05 and 5.06 of this First Supplemental Indenture and Section 1005 of the Indenture with respect to the Notes if before or after the time for such compliance the
Holders of at least a majority in principal amount of the outstanding Notes (including additional Notes, if any) shall either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition
shall remain in full force and effect.

 [Reverse Side of Note] 

3.375% Note due 2020 

This Note is one of the duly authorized debentures, notes or other evidences of Indebtedness (herein called the “Securities”)
of the Company (herein called the “Notes”) issued and to be issued in one or more series under an Indenture dated as of September 14, 2010 (the “Base Indenture”), as amended by a First Supplemental Indenture dated as of
September 14, 2010 (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and Wells Fargo Bank, National Association, a national banking association (herein called
the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of Notes represented hereby), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is a global Note
representing the Company’s 3.375% Notes due 2020 in the aggregate principal amount of $            . The Notes are issuable only in fully registered form without coupons, in
minimum denominations of $2,000 with integral multiples of $1,000 in excess thereof. 
 The amount of interest payable on any
Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve 30-day months. If the date of Maturity or an Interest Payment Date falls on a day that is not a Business Day, the related payment of principal or interest
will be made on the next succeeding Business Day as if made on the date the payment was due. No interest will accrue on such payment for the period from and after such Interest Payment Date to the date of such payment on the next succeeding Business
Day. 
 Payment of the principal of and any interest on this Note will be made at the Corporate Trust Office of the Trustee or
such other Office or Agency of the Company as may be designated for such purpose, in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts and in immediately available funds;
provided, however, that at the option of the Company, payment of interest may be paid by wire transfer in immediately available funds if the Holder has provided to the Company and the Trustee wire instructions at least five Business
Days prior to the applicable payment date or by check mailed to the address of such Holder as it appears on the books of the Securities Registrar if such Holder has not provided wire instructions. 

The Notes shall not be redeemable at the option of any Holder thereof, whether upon the occurrence of any particular circumstances or
otherwise. The Notes will be redeemable, as a whole or in part, at the option of the Company, at 
  

 A-4 








 
any time or from time to time, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Notes to be redeemed and (b) the sum of the present values of the
Remaining Scheduled Payments on such Notes discounted to the Redemption Date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the applicable Treasury Rate plus 15 basis points. Accrued
and unpaid interest will be paid to the Redemption Date. 
 In the event that the Company chooses to redeem less than all of the
Notes, selection of the Notes for redemption will be made by the Trustee not more than 60 days prior to the Redemption Date by the Trustee on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate. 

No Notes of a principal amount of $2,000 or less shall be redeemed in part. Notice of redemption will be mailed by electronic
transmission or first-class mail at least 30 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address. On and after the Redemption Date, interest will cease to accrue on the Notes or
portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable Redemption Price. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a
Maturity comparable to the remaining term of the Notes to be redeemed, 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 Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, the
Reference Treasury Dealer Quotations for that Redemption Date. 
 “Reference Treasury Dealer” means Banc of America
Securities LLC and Goldman, Sachs & Co. and any successor firm; provided that, if any of Banc of America Securities LLC or Goldman, Sachs & Co. ceases to be a primary U.S. Government securities dealer, the Company will substitute
another nationally recognized investment banking firm that is a primary U.S. Government securities dealer. 
 “Reference
Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by an independent investment bank appointed by the Company, 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 Trustee by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding that Redemption Date. 

 

 A-5 








 “Remaining Scheduled Payments” means the remaining scheduled payments of principal
of and interest on the Notes that would be due after the related Redemption Date but for that redemption. If that Redemption Date is not an Interest Payment Date, the amount of the next succeeding scheduled interest payment on the Notes will be
reduced by the amount of interest accrued on the Notes to such Redemption Date. 
 “Treasury Rate” means, with respect
to any Redemption Date for the Notes, the rate per annum equal to the semiannual equivalent yield to Maturity (computed as of the third Business Day immediately preceding that Redemption Date) of the Comparable Treasury Issue, assuming a price for
the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date. 

The Indebtedness evidenced by this Note is, to the extent provided in the Indenture, senior and unsecured and will rank equal in right of
payment to all other existing and future senior unsecured obligations of the Company. 
 The Notes are initially limited to
$650,000,000 aggregate principal amount. The Company may, without notice to or consent of the Holders or beneficial owners of the Notes, issue additional Notes having the same ranking, interest rate, Maturity and the same terms as to status,
redemption or otherwise, as the Notes, provided that any such additional Notes shall be fungible with the original Notes for U.S. federal income tax purposes. Any such additional Notes issued will be considered part of the same series of Securities
under the Indenture as the Notes. 
 The Notes are not entitled to the benefit of any sinking fund. 

The Indenture imposes certain limitations on the ability of the Company to, among other things, merge or consolidate with any other
Person, and requires that the Company comply with certain further covenants, all of which are applicable to this Note. All such covenants and limitations are subject to a number of important qualifications and exceptions. The Indenture requires the
Company, within 120 days after the end of the Company’s fiscal year, to furnish to the Trustee a statement as to compliance with the Indenture. 

The Indenture contains provisions for the defeasance at any time of (a) the entire Indebtedness of the Company on this Note and
(b) certain restrictive covenants and the related defaults and Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note. Under the Indenture, Events of Default include
(i) default in the payment of principal (or premium, if any) or any Additional Amounts with respect to such principal or premium on the Notes when due; (ii) default in the payment of any interest or any Additional Amounts with respect to
such interest on the Notes when due, continued for 30 days; (iii) failure to perform any other covenant or 
  

 A-6 








 
warranty of the Company contained in the Indenture or the Notes continued for 90 days after written notice from the Trustee or the Holders of not less than 25% in aggregate principal amount of
the Notes then outstanding; (iv) certain events of bankruptcy, insolvency or reorganization of the Company; or (v) an event of default as defined in any mortgage, indenture or instrument under which there may be issued, or by which there
may be secured or evidenced, any Indebtedness of the Company or any Subsidiary for borrowed money with a principal amount in excess of $100,000,000 (other than nonrecourse obligations), whether such Indebtedness now exists or shall hereafter be
created, occurs and results in an amount of such Indebtedness in excess of $100,000,000 becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and such acceleration shall not be rescinded or
annulled, or such Indebtedness shall not have been discharged, within a period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least
25% in principal amount of the Notes then outstanding (including additional Notes, if any), a written notice specifying such event of default and requiring the Company to cause such acceleration to be rescinded or annulled or to cause such
Indebtedness to be discharged and stating that such notice is a “Notice of Default” under Section 603 of the Base Indenture; provided, however, that if any event of default or acceleration referred to in this subsection (v) shall
cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred. 

If an Event of Default with respect to this Note shall occur and be continuing, the principal hereof may be declared due and payable in
the manner and with the effect provided in the Indenture. 
 The Indenture contains provisions permitting, with certain
exceptions therein provided, the Company and the Trustee, with the consent of the Holders of a majority in aggregate principal amount of the outstanding Notes to execute supplemental indentures for the purpose of, among other things, adding any
provisions to or changing or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying the rights of the Holders of the Notes. 

The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the outstanding Notes, on
behalf of all of the Holders of all Notes, to waive any past default with respect to the Notes and its consequences, except a default in the payment of the principal of, any premium or interest on, or any Additional Amounts with respect to the
Notes, or in respect of a covenant or other provision which, under the terms of the Indenture, cannot be modified or amended without the consent of the Holder of each outstanding Note. Any such consent or waiver by the registered Holder of this Note
shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange for or in place hereof 

 

 A-7 








 
(whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note. 

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in this Note, or for any claim based
thereon or otherwise in respect thereof, shall be had against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company, either directly or through the Company, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that the Indenture and the obligations issued thereunder are solely corporate obligations, and that no such personal liability
whatsoever shall attach to, or is or shall be incurred by, the incorporators, shareholders, officers or directors, as such, of the Company, or any of them, because of the creation of the Indebtedness thereby authorized, or under or by reason of the
obligations, covenants or agreements contained in the Indenture or in this Note or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute, of, and any
and all such rights and claims against, every such incorporator, shareholder, officer or director, as such, because of the creation of the Indebtedness authorized, or under or by reason of the obligations, covenants or agreements contained in the
Indenture or in this Note or implied therefrom, are expressly waived and released as a condition of, and as a consideration for, the execution of the Indenture and the issuance of this Note. 

If any provision of the First Supplemental Indenture, including any definitions contained therein, is inconsistent with any other
provision or definition contained in the Base Indenture, the provisions of the First Supplemental Indenture shall be controlling for the purposes of this Note. 

No reference herein to the Indenture and no provision of this Note or the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the amount of principal of and interest on this Note herein provided, and 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 Note is registrable in the
Security Register, upon surrender of this Note for registration of transfer at any Office or Agency, duly endorsed, signature guaranteed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof, signature guaranteed, or his attorney duly authorized in writing, and thereupon a new Note of this series for the same aggregate principal amount will be issued to the designated transferee or
transferees. The Trustee initially shall be the Security Registrar and the Paying Agent for the Notes. 
  

 A-8 








 No service charge shall be made for any such registration of transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary. 

Except as otherwise provided in or pursuant to the Indenture, this global Note shall be exchangeable for definitive Notes only if
(i) the Depositary is at any time unwilling, unable or ineligible to continue as Depositary and a successor depositary is not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii) the Depositary
ceases to be a clearing agency registered under the Exchange Act of 1934, (iii) the Company executes and delivers to the Trustee a Company Order to the effect that this global Note shall be so exchangeable or (iv) an Event of Default has

Trustee Notes of this series in definitive registered form, containing identical terms and in an aggregate principal amount equal to the principal amount of this global Note at the time outstanding in exchange for this global Note. 

This Note shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made or
instruments entered into and, in each case, performed in said state. 
 All terms used in this Note which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.
