which it may be so terminated) or (y) the net amount determined assuming no such termination.

 Section 2.02. Creation of the Notes. In accordance with Section 2.01 of the
Indenture, the Company hereby creates the Notes as a separate series of its Securities issued pursuant to the Indenture. The Notes shall be issued initially in an aggregate principal amount of €500,000,000. 

Section 2.03. Form of the Notes. The Notes shall each be issued in the form of a Global Security, duly executed by the
Company and the Guarantors and authenticated by the Trustee, which shall be deposited with, or on behalf of Clearstream or Euroclear, and registered in the name of USB Nominees (UK) Limited, as nominee of Elavon Financial Services Limited, a common
depositary for the accounts of Clearstream and Euroclear. The Notes shall be substantially in the form of Exhibit A attached hereto. So long as the Common Depositary or its nominee, is the registered owner of a Global Security, the
Common Depositary or its nominee, as the case may be, shall be considered the sole owner or Holder of the Notes represented by such Global Security for all purposes under the Indenture and under such Notes. Ownership of beneficial interests in such
Global Security shall be shown on, and transfers thereof will be effective only through, records maintained by the Common Depositary or its nominee (with respect to beneficial interests of participants) or by participants or Persons that hold
interests through participants (with respect to beneficial interests of beneficial owners). Notwithstanding the foregoing, nothing herein shall (x) prevent the Company or the Trustee from giving effect to any written communication, proxy or

Holders thereof, together with all accrued and unpaid interest thereon, on March 17, 2022 (the “Maturity Date”). 

(c) Payment of Principal and Interest. The Notes shall bear interest at 1.250% per annum, from and including
March 17, 2015, or from the most recent Interest Payment Date (as defined hereafter) on which interest has been paid or provided for until the principal thereof becomes due and payable, and on any overdue principal. Interest will be computed on
the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or

Business Day immediately preceding such Interest Payment Date (each such date, a “Regular Record Date” for the purposes of the Notes under this Third Supplemental Indenture). If any Interest Payment Date would otherwise be a day
that is not a Business Day, that Interest Payment Date will be postponed to the next date that is a Business Day. If the Maturity Date of the Notes falls on a day that is not a Business Day, the related payment of principal and interest will be made
on the next Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next Business Day. As specified in paragraph 12 on the reverse of the

minimum denomination of €100,000 and integral multiples of €1,000 in excess thereof. All payments of principal, Redemption Price, any purchase price relating to a Change of Control Offer, any Additional Amounts (if any) and accrued unpaid
interest in respect of the Notes shall be made by the Company as set forth in the Notes. 
 (e) Place of Payment and
Appointment and Funding. All payments of interest and principal, including payments made upon any redemption of the Notes, Change of Control Offer and any Additional Amounts (if any) shall be payable at the office or agency of the Company
maintained for such purposes in London, England, which shall initially be the principal corporate trust office of the Paying Agent; provided, however, that payment of interest may be made at the option of the Company by (i) by check mailed to
the address of the Person entitled thereto as such address shall appear in the Securities Register or (ii) by wire transfer to an account maintained by the Person entitled thereto as specified in the Securities Register; and provided that the

 On or prior to the date that any payments of interest and principal, including
payments made upon any redemption of the Notes, any purchase price relating to a Change of Control Offer and any Additional Amounts (if any), or any other amount payable in respect of the Notes is due and payable, the Company shall deposit with the
Paying Agent in London, England, an amount of money in euros sufficient to pay any and all such amounts due and payable in respect of the Notes on such payment date. 

(f) Issuance in Euro. Initial Holders will be required to pay for the Notes in euros, and all payments of interest and
principal, including payments made upon any redemption of the Notes, any purchase price relating to a Change of Control Offer and any Additional Amounts (if any), will be made in euros; provided that if the euro is unavailable to the Company due to
the imposition of exchange controls or other circumstances beyond the Company’s control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the
settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to the Company or so used. If the euro is
unavailable to the Company, the amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date
or, if the U.S. Federal Reserve Board has not mandated a rate of conversion, the rate will be determined in the Company’s sole discretion on the basis of the most recently available market exchange rate for the euro. Any payment in respect of
the Notes so made in U.S. dollars will not constitute an Event of Default under the Notes. Neither the Trustee nor the Paying Agent shall have any responsibility for obtaining exchange rates, affecting conversions, making calculations or otherwise
handling re-denominations. Any references elsewhere in this Third Supplemental Indenture or the Notes to payments being made in euros notwithstanding, payments shall be made in U.S. dollars to the extent set forth in this Section 2.04(f).

from time to time, without the consent of or notice to the Holders, create and issue further securities having the same interest rate, maturity and other terms (except for the issue date, the public offering price and the first Interest Payment
Date) as, ranking equally and ratably with, the Notes. Additional Notes issued in this manner shall be consolidated with and shall form a single series with the previously outstanding Notes. 

(i) Redemption. The Notes are subject to redemption by the Company in whole or in part in the manner described herein.

 (j) Guarantees. The payment of the principal and any accrued and unpaid interest on the Notes, whether at the
Maturity Date, by acceleration, by redemption or otherwise, is fully, unconditionally and irrevocably guaranteed, jointly and severally, by the Guarantors as provided in Article X of the Indenture.

the Notes as described under Section 3.01, each Holder of Notes will have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to the offer described below (the “Change of Control
Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (the “Change of Control Payment”). 

(b) Within 30 days following the date upon which the Change of Control Triggering Event occurred, or at the Company’s option, prior to
any Change of Control but after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Company will send, by first class mail, a notice to each Holder of Notes, with a copy to the Trustee, which
notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be
required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being
consummated on or prior to the Change of Control Payment Date. Holders of Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to surrender their Notes, with the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice, or transfer their Notes to the Paying Agent by book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to
the close of business on the third Business Day prior to the Change of Control Payment Date. 
 (c) On each Change of Control Payment Date,
the Company will, to the extent lawful, (i) accept for payment all Notes or portions of 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 Notes or portions of Notes properly tendered pursuant to the applicable Change of Control Offer and (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’
Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased. 
 (d) 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 such an offer made by the Company
and such third party purchases all Notes properly tendered and not withdrawn under its offer. 

  
 14 








 (e) 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 Notes as a result of a 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 Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the
Change of Control Offer provisions of the Notes by virtue of such conflicts.

	€            		No.:            

 FLOWSERVE CORPORATION, a New
York corporation (herein called the “Company”), for value received, hereby promises to pay to USB Nominees (UK) Limited, as nominee of Elavon Financial Services Limited, UK Branch, a common depositary for the accounts of Euroclear and
Clearstream (the “Common Depositary”), or registered assigns, the principal sum of €            or such other principal amount as shall be set forth on Schedule I hereto on
March 17, 2022 and to pay interest thereon at the rate of 1.250% per annum from and including March 17, 2015, or from the most 

  
 Exhibit A - Page 1 








 
recent Interest Payment Date to which interest has been paid or duly provided for, annually on March 17 of each year, commencing on March 17, 2016 (each, an “Interest Payment
Date”), until the principal hereof is paid or made available for payment. 
 The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, except as provided in the Indenture hereinafter referred to, be paid to the Person in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the Business Day
immediately preceding such Interest Payment Date (each such date, a “Regular Record Date”). If any Interest Payment Date would otherwise be a day that is not a Business Day, that Interest Payment Date will be postponed to the next date
that is a Business Day. If the Maturity Date of the Notes falls on a day that is not a Business Day, the related payment of principal and interest will be made on the next Business Day as if it were made on the date such payment was due, and no
interest will accrue on the amounts so payable for the period from and after such date to the next Business Day. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record
Date and either may be paid to the Person in whose name this Note (or one or more predecessor Notes) 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 the Holders not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. 

Payment of the principal of and interest on this Note (including, without limitation, any Redemption Price, any purchase price relating to a
Change of Control Offer or any Additional Amounts (if any)) will be made at the office or agency of the Company maintained for that purpose pursuant to the Indenture (initially the principal corporate trust office of the Paying Agent in London,
England (the “Corporate Trust Office”) or by electronic means, in euros; provided, however, that if the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s
control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking
community, then all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to the Company or so used. If the euro is unavailable to the Company, the amount payable on any date in euro will be converted into
U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, if the U.S. Federal Reserve Board has not mandated a rate of conversion, the rate will
be determined in the Company’s sole discretion on the basis of the most recently available market exchange rate for the euro. Any references elsewhere in this Note or the Third Supplemental Indenture to payments being made in euros
notwithstanding, payments shall be made in U.S. dollars to the extent set forth in this paragraph. Payment of interest may be made at the option of the Company (i) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Securities Register or (ii) by wire transfer to an account maintained by the Person entitled thereto as specified in the Securities Register. Payments of principal and interest at maturity will be made against


  
 Exhibit A - Page 2 








 
presentation of this Note at the Corporate Trust Office (or such other office as may be established pursuant to the Indenture), by check or wire transfer. However the Company shall pay principal
of and interest (including, without limitation, any Redemption Price, any purchase price relating to a Change of Control Offer or any Additional Amounts (if any)) on a Note in global form registered in the name of or held by USB Nominees (UK)
Limited, as nominee of Elavon Financial Services Limited, as common depositary for the accounts of Clearstream and Euroclear, or such other Depositary as any officer of the Company may from time to time designate, or its respective nominee, by wire
in immediately available funds to such Depositary or its nominee, as the case may be, as the registered Holder of this Note in global form. Interest on the Notes will be computed on the basis of the actual number of days in the period for which
interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or March 17, 2015 if no interest has been paid on the Notes), to but excluding the next scheduled Interest
Payment Date. 
 Reference is hereby made to the further provisions of this Note set forth on the reverse side hereof, which further
provisions shall for all purposes have the same effect as though fully set forth at this place. 
 Unless the Certificate of Authentication
hereon has been executed by the Trustee or an authenticating agent under the Indenture referred to on the reverse hereof by the manual signature of one of its authorized officers, this Note shall not be entitled to any benefit under the Indenture or

 (Reverse of Note) 

FLOWSERVE CORPORATION 
 1.250%
SENIOR NOTE DUE 2022 
 1. This Note is one of a duly authorized issue of securities of the Company designated as its 1.250% Senior Notes
due 2022 (the “Notes”) unlimited in aggregate principal amount issued and to be issued under the Indenture, dated as of September 11, 2012 (the “Base Indenture”), between the Company and U.S. Bank National Association, as
trustee (herein called the “Trustee,” which term includes any successor Trustee under the Indenture), and the Third Supplemental Indenture, dated as of March 17, 2015 (the “Third Supplemental Indenture” and the Base
Indenture, as so supplemented by the Third Supplemental Indenture and as it may be further supplemented or amended from time to time, the “Indenture”), among the Company, the guarantors named therein and the Trustee. Reference is hereby
made to the Indenture for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered. The indebtedness of the Company
evidenced by the Notes, including the principal thereof and interest thereon (including post-default interest), will constitute unsecured and unsubordinated indebtedness of the Company and will rank equally in right of payment with all of the
Company’s current and future unsecured and unsubordinated indebtedness. 
 2. At any time prior to December 17, 2021, the Notes
are subject to redemption, in whole or in part, from time to time, at the Company’s option at a Redemption Price equal to the greater of: 
  

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

  

	 	(ii)	the sum of the present values of the Remaining Scheduled Payments of the Notes to be redeemed, discounted to the date of redemption on an annual basis (ACTUAL/ACTUAL ICMA) at the Comparable Government Bond Rate plus 25
basis points. 

 At any time on or after December 17, 2021, the Company may redeem the Notes, in whole or in part from
time to time, at its option, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed. 
 In each case, the
Company will also pay the accrued and unpaid interest on the principal amount being redeemed to, but excluding, the Redemption Date. 
 Any
notice to Holders of Notes of a redemption pursuant to this paragraph 2 hereof will include, among other things set forth in the Indenture, the Redemption Date, the Redemption Price (or the methodology for determining the Redemption Price), the
amount of accrued and unpaid interest to the Redemption Date, and the name and address of the Paying Agent. 

  
 Exhibit A - Page 6 








 3. Upon the occurrence of a Change of Control Triggering Event, unless the Company has given
written notice with respect to a redemption of the Notes pursuant to paragraph 2 of this Note, each Holder of Notes will have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to the Change of Control
Offer, at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but excluding, the date of purchase. The Notes may also be redeemed pursuant to Section 3.03 of the Third Supplemental
Indenture in the circumstances set forth therein. 
 4. The payment of the principal of and interest on the Notes will be fully and
unconditionally guaranteed by the Guarantors, on the terms set forth in the Indenture. 
 5. If an Event of Default with respect to the
Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

6. 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 Guarantors and the rights of the Holders of Notes under the Indenture at any time by the Company, the Guarantors and the Trustee with the consent of the Holders of a majority in aggregate principal amount of Notes
at the time outstanding. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Notes at the time outstanding, on behalf of the Holders of all Notes, 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 therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 

7. No reference herein to the Indenture and no provisions 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 interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed. 

8. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered on the
Securities Register of the Company, upon surrender of this Note for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instruction of transfer in form satisfactory to the Company, and duly executed
by the Holder hereof or such Holder’s attorney, duly authorized in writing, on which instruction the Company can rely, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued
to the designated transferee or transferees. 
 9. The Notes are issuable only in fully registered form, without coupons, in minimum
denominations of €100,000 or any amount in excess thereof which is an integral multiple of €1,000. As provided in the Indenture, and subject to certain 

  
 Exhibit A - Page 7 








 
limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes in authorized denominations, as requested by the Holder surrendering the same. 

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

beneficial owner or member received directly its beneficial or distributive share of the payment; 

  

	 	(3)	to the extent any tax, assessment or other governmental charge that would not have been imposed but for the failure of the Holder or any other person to comply with certification, identification or information reporting

therein or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

presentation is required) by or on behalf of a Holder of Notes, if such payment could have been made without such withholding by presenting the relevant Note to at least one other paying agent in a member state of the European Union;



  
 Exhibit A - Page 9 









	 	(8)	to the extent any tax, assessment or other governmental charge would not have been imposed but for the presentation by the Holder of any Note, where presentation is required, for payment on a date more than 30 days
after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; 

  

	 	(9)	to any tax, assessment or other governmental charge imposed under Sections 1471 through 1474 of the Code (or any amended or successor provisions), any current or future regulations or official interpretations thereof,
any agreement entered into pursuant to Section 1471(b) of the Code or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such
sections of the Code; or 

  

	 	(10)	in the case of any combination of items (1), (2), (3), (4), (5), (6), (7), (8) and (9).
