notice will be mailed to Holders of the applicable Notes, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the applicable 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 that notice is mailed (a “Change of Control Payment Date”). The notice will, if mailed prior to the date of consummation of the Change of
Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event with respect to the applicable Notes occurring on or prior to the Change of Control Payment Date. 







 On each Change of Control Payment Date, the Company will, to the extent lawful:
(i) accept for payment all applicable Notes or portions of such Notes properly tendered pursuant to the applicable Change of Control Offer; (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of
all such Notes or portions of such Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the applicable Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of
applicable Notes or portions of applicable Notes being repurchased and that all conditions precedent provided for in the Indenture to the Change of Control Offer and to the repurchase by the Company of the applicable Notes pursuant to the Change of
Control Offer have been met. 
 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 made by the Company and the third party repurchases all applicable Notes properly
tendered and not withdrawn under its offer. In addition, the Company will not repurchase any applicable Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture with respect to such
Notes, other than a default in the payment of the Change of Control Payment upon a related Change of Control Triggering Event. The Company will 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 applicable Notes as a result of a related Change of Control Triggering Event. To the extent that the provisions of any such
securities laws or regulations conflict with the Change of Control Offer provisions of the applicable 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 applicable Notes by virtue of any such conflict. 
 10. No Sinking
Fund. The Company shall have no obligation to redeem or purchase the Notes pursuant to any sinking fund or analogous provisions, or at the option of a Holder thereof. 
 11. Global Notes. The Global Notes representing the Notes shall be deposited on behalf of the Holders of the Notes represented thereby with the Trustee, as custodian for the Depositary, and
registered in the name of the Depositary or a nominee of the Depositary for the accounts of Participants, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of a Global Note may from
time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as hereinafter provided. The Depositary for the Notes shall initially be The Depository Trust Company, a New York corporation.

 12. Sections 1302 and 1303 of the Original Indenture shall apply to the Notes, in accordance with the provisions, terms
and conditions set forth in Article Thirteen thereof.

 Solely with respect to the Notes (and not with respect to any other series of Securities that may be issued under the
Original Indenture), Sections 201 through 205 of the Original Indenture are hereby amended by deleting those Sections in their entirety and by replacing them with the following: 

“Section 201. Form. 
 General. The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, Exhibit B, Exhibit C and Exhibit D attached
hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The written order of the Company

Global Notes. Notes issued in global form shall be substantially in the form of Exhibit A, Exhibit B, Exhibit
C and Exhibit D attached hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of
Exhibit A, Exhibit B, Exhibit C and Exhibit D attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global
Note shall represent such of the outstanding 2015 Notes, 2018 Notes, 2023 Notes or 2043 Notes, as applicable, as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of such Notes outstanding from
time to time endorsed thereon and that the aggregate principal amount of such Notes outstanding represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges. Any endorsement of a Global Note to reflect the
amount of any increase or decrease in the aggregate principal amount of outstanding 2015 Notes, 2018 Notes, 2023 Notes or 2043 Notes, as applicable, represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee,
in accordance with instructions given by the Holder thereof as required by Section 305(B) hereof.

sixth Supplemental Indenture (and not with respect to the Existing Notes), the phrase “10% of Consolidated Net Tangible Assets” in clause (5) of Section 1009 of the Original

 Section 3.4 Registration, Registration of Transfer and Exchange. Solely with respect to the Notes (and not

“Section 305. Registration, Registration of Transfer and Exchange. 

(A) Security Registrar and Paying Agent. The Company shall maintain an office or agency where Notes may be presented for
registration of transfer or for exchange (“Security Register” or “Security Registrar”) and an office or agency where Notes may be presented for payment. The Security Registrar shall keep a register of
the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Security Registrar” includes any co-registrar and the term “Paying Agent”
includes any additional paying agent. The Company may change any Paying Agent or Security Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Paying Agent or Security Registrar not a
party to the Indenture. If the Company fails to appoint or maintain another entity as Security Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Security Registrar.

 (B) Transfer and Exchange. 
 (a) Transfer and Exchange of Global Notes. The Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee, except if DTC is at
any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 days. In such event, the Company will issue the Notes in definitive form in exchange for the Global Notes representing
such Notes and an owner of a beneficial interest in a Global Note will be entitled to physical delivery in definitive form of Notes represented by such Global Note equal in principal amount to such beneficial interest and to have such Notes
registered in its name. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and
exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. 

(c) Legends. The following legend shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture
unless specifically stated otherwise in the applicable provisions of this Indenture. 
 Each Global Note shall bear a legend in
substantially the following form: 







 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS
NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO
SECTION 305(B) OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 305(B)(a) OR 306 OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION
PURSUANT TO SECTION 309 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF PRECISION CASTPARTS CORP.” 

(d) Cancellation and/or Adjustment of Global Notes. 

(i) At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a
particular Global Note has been repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 309. At any time prior to such cancellation, if any
beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such
Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or
transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

Exchanges. 
 (i) To permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Global Notes and Definitive Notes upon the Company’s order or at the Security Registrar’s request.

payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 304,
1107 and 906 hereof). 
 (iii) All Global Notes and Definitive Notes issued upon any registration of transfer or
exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this

(iv) The Company shall not be required to register the transfer of or to exchange a Note between a record date and the
next succeeding Interest Payment Date.

treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if any, and interest on such Notes and for all other purposes, and neither the Trustee nor the
Company shall be affected by notice to the contrary.”

 Precision Castparts
Corp., a corporation duly organized and existing under the laws of Oregon (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to
            or registered assigns, the principal sum of             Dollars on December 20, 2015 and to pay interest thereon
from December 20, 2012 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually on June 20 and December 20 in each year, commencing June 20, 2013, at the rate of
0.70% per annum, until the principal hereof is paid or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at the rate of 0.70% per annum on any overdue principal and premium and on
any overdue installment of interest. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note is registered at the close of
business on the Regular Record Date for such interest, which shall be the June 5 or December 5 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the Notes of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months. 
 Payment of the principal of (and premium, if any) and interest on this Note
will be made at the office or agency of the Company maintained for that purpose in New York, New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer to an account
maintained by the Person entitled thereto as specified in the Security Register, provided that such Person shall have given the Trustee written wire instructions. 
 Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any
purpose. 
 This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to
be issued in one or more series under an Indenture, dated as of December 17, 1997, as amended by indentures supplemental thereto (the “Indenture”, which term as used herein includes the twenty-sixth supplemental indenture dated
December 20, 2012, establishing the title, form and terms of $500,000,000 aggregate principal amount of the Company’s 0.70% 







 
Senior Notes due 2015) among the Company and U.S. Bank National Association (successor in interest to The First National Bank of Chicago), as Trustee (herein called the “Trustee”, which
term includes any successor trustee under the Indenture), 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 one of the series designated on the face hereof, the initial principal amount of which is
$500,000,000, but the aggregate amount of which is unlimited. 
 The Indenture contains provisions for defeasance at any time of the entire
Indebtedness of this Note or certain restrictive covenants and Events of Default with respect to this Note, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of the Notes 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 Notes 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 Notes 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 Notes of each series at the time Outstanding, on behalf of the Holders
of all Notes 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 Note shall be conclusive
and binding upon such Holder and upon all future Holders of this Note and of any Note 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 Note.

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and any premium and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 
 The Notes of this series are issuable only in registered form without coupons in denominations of $2,000 or any integral multiple of $1,000 in excess of $2,000. The transfer of the Notes may be registered
and the Notes may be exchanged as provided in the Indenture. The Security Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay a

Senior Notes due 2043) among the Company and U.S. Bank National Association (successor in interest to The First National Bank of Chicago), as Trustee (herein called the “Trustee”, which
term includes any successor trustee under the Indenture), 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 one of the series designated on the face hereof, the initial principal amount of which is
$500,000,000, but the aggregate amount of which is unlimited. 
 The Indenture contains provisions for defeasance at any time of the entire
Indebtedness of this Note or certain restrictive covenants and Events of Default with respect to this Note, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of the Notes 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 Notes 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 Notes 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 Notes of each series at the time Outstanding, on behalf of the Holders
of all Notes 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 Note shall be conclusive
and binding upon such Holder and upon all future Holders of this Note and of any Note 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 Note.

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

and the Notes may be exchanged as provided in the Indenture. The Security Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay a
sum sufficient to cover any taxes and fees required by law or permitted by the Indenture. 
 Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as 







 
contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
 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, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 All terms
used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
