 EXHIBIT 10.1 
 FORM OF 
 PERFORMANCE SHARE AWARD AGREEMENT 
 (2005 Plan Version) 
 This Performance Share
Award Agreement (this “Agreement”) is entered into as of December 15, 2008 (the “Grant Date”) between GrafTech International Ltd. (the “Corporation”) and
                                        
             (the “Participant”) pursuant to the GrafTech International Ltd. 2005 Equity Incentive Plan (the “Plan”). 
 BACKGROUND 
 The Plan allows the
Corporation to provide rewards and incentives to employees of the Company by granting them a stock-based award. The Board or the Compensation Committee has determined that it would be in the best interest of the Corporation and its stockholders to
grant the Peformance Shares to the Participant under the Plan. 
 The Participant agrees to enter into this Agreement with the Corporation.
The Participant acknowledges that this Agreement contains, among other things, certain restrictions, including limitations on the Participant’s right to compete against the Corporation and its subsidiaries during and following termination of
employment. Accordingly, in consideration of the grant of Perfomance Shares to the Participant under the Plan, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally
bound, the parties agree as follows: 
 ARTICLE I 
 DEFINITIONS 
 Whenever capitalized terms are used in this Agreement, they shall have the meanings set
forth in this Agreement or, if not defined in this Agreement, as set forth in the written employment agreement between the Participant and the Company or, if not defined in this Agreement and if not defined in such an employment agreement or there
is no such employment agreement, as set forth in the Plan. A copy of the Plan has been made available to the Participant and the terms of the Plan are incorporated herein by reference. 
 “Cause” shall mean: 
 (i) gross neglect or willful and continuing refusal by the Participant to substantially perform his or her duties or responsiblities for or owed to the Company (other than due to death, Disability or Retirement); 
 (ii) breach by the Participant of his or her confidentiality obligations owed to the Company; 
 (iii) willful engagement by the Participant in conduct which is demonstrably injurious to the Company (including a breach by the
Participant of his or her confidentiality, non-competition, non-disparagement or non-solicitation obligations owed to the Company); or 
 (iv) conviction or plea of nolo contendere by the Participant to a felony or a misdemeanor involving dishonesty or financial or economic wrongdoing (such as fraud, embezzlement, insider trading, bribery, theft, price
fixing, graft of corrupt payments, perjury or false certification. 

 ARTICLE II 
 GRANT OF PERFORMANCE SHARES 
 2.1 Grant of Performance Shares. The Participant is hereby
granted a Performance Share Award with respect to              shares of Common Stock (the “Target Award”) subject to the adjustments, restrictions, and conditions set
forth in this Agreement. References in this Agreement to “Performance Shares” mean the unfunded and unsecured right to receive the shares of Common Stock issuable. 
 2.2 Adjustments to Target Award. The number of Shares issuable pursuant to this Award is subject to upward or downward adjustment, as described in
Section 3.1, based on the degree to which Performance Measures, as determined by the Committee, are achieved. 
 ARTICLE III

 ADJUSTMENTS TO TARGET AWARD AND VESTING OF PERFORMANCE SHARES 
 All of the Performance Shares are unvested as of the Grant Date. Subject to Section 7.2, Performance Shares shall vest at such times as described
in, and to the extent provided in, Section 3.2 or 3.3, in each case subject to the limitations set forth in Section 3.4. Subject to Section 7.2, all unvested Performance Shares shall be forfeitable as set forth in Sections 3.2 and 3.4
and shall be non-transferable as set forth in Section 4.2. All vested Performance Shares shall become non-forfeitable and transferable at the time they first vest, although: 
 (i) transferability may be subject to pre-clearance, blackout, registration and other restrictions under the Company’s insider
trading and other compliance policies and procedures; 
 (ii) transferability may be restricted under Section 4.3 until
all Withholding Requirements (as defined herein) are satisfied; and 
 (iii) transfers by executive officers should be
reviewed in advance to determine if there would be any potential liability for short-swing profits under Section 16(b) of the Exchange Act. 
 3.1 Adjustment to Target Award; Earned Shares. The Target Award for a particular fiscal year of the Company during which specific performance measures are expected to be achieved (each a “Performance Year”) is subject to
upward or downward adjustments as follows. By February 28 of each of 2010, 2011, and 2012, one-third of the Target Award will be multiplied by a percentage reflecting the degree to which performance criteria established by the Compensation
Committee for such Performance Year have been achieved. The resulting number of Performance Shares (“Earned Shares”) will be set aside as unvested Earned Shares for the Participant as of the date of such determination; provided that the
Participant is still employed by the Company on such date. 
  

 2 

 3.2 Vesting and Forfeiture. To the extent not sooner vested and unless previously forfeited
pursuant to Section 3.4, and subject to the forfeiture provisions set forth below in this Section 3.2, unvested Performance Shares shall vest as follows: 
 (i) All unvested Performance Shares that have become Earned Shares shall vest under this Section at the close of business on
February 29, 2012. 
 (ii) For any Performance Year in which the minimum threshold Performance Measure was not achieved,
one-third of the Target Award shall cease to vest and shall be forfeited as of the last day of such Performance Year. 
 (iii)
For any Performance Year in which the minimum threshold Performance Measure was achieved but less than the targeted Performance Measure was achieved, the number of Target Award Performance Shares equal to the difference between (a) the Earned
Shares for such Performance Year and (b) one-third of the Target Award shall cease to vest and shall be forfeited as of the last day of such Performance Year. 
 3.3 Change in Control. Unless previously forfeited pursuant to Section 3.2 or 3.4, and provided Participant is an employee of the Company upon the Change of Control, all unvested Performance Shares shall
vest upon the occurrence of a Change in Control (and shall also thereupon be deemed to be vested Earned Shares). 
 3.4 Effect of
Termination of Employment and Other Events on Vesting; Forfeiture of Unvested Performance Shares. Unless otherwise determined by the Board or the Compensation Committee and subject to Section 7.2, all unvested Performance Shares (including
unvested Earned Shares) shall cease to vest and shall be forfeited upon the earliest to occur of: 
 (i) the time of
notification of the termination of the Participant’s employment by the Company for Cause or Detrimental Conduct; 
 (ii)
the date the Participant’s employment with the Company terminates for any reason including resignation, Retirement, Disability, or death, but not including mandatory retirement or retirement from the Company at any time after attaining age 65
with at least ten years of employment with the Company (in which event Participant’s Earned Shares as of the date of retirement will vest in accordance with Section 3.2 and 3.3); or 
 (iii) the date on which the Board or the Compensation Committee takes such action pursuant to Article V (or such later date as may be
specified by the Board or the Compensation Committee). 
 3.5 Effective Date of Termination of Employment or Retirement. For purposes
hereof, except as otherwise set forth in Section 3.4(i), the date of Disability, resignation, Retirement, or termination of employment means the last date on the Company’s payroll as an active employee, even if a different date is used for
administrative convenience in connection with employee retirement, benefit or welfare plans.

 ARTICLE IV 
 PROCEDURES AFFECTING PERFORMANCE SHARES 
 4.1 Delivery of Performance Shares. 
 (i) The unvested Earned Shares will be delivered to the Participant in book entry or other electronic form by causing the unvested Earned
Shares to be credited to an account for the Participant maintained by the Corporation’s transfer agent or as may otherwise be designated from time to time by the Corporation to assist in the administration of the Plan (the
“Participant’s Account”). 
 (ii) The unvested Earned Shares will be credited to the Participant’s Account
within thirty (30) days following the date such Earned Shares are set aside as unvested Earned Shares in accordance with Section 3.1. 
 (iii) Such Earned Shares shall be subject to such stop transfer instructions as provided in connection with the Company’s insider trading and other compliance policies and procedures, except to the extent that
any such Earned Shares may be sold pursuant to Section 4.3 to satisfy Withholding Requirements. Upon forfeiture of any Performance Shares, the Broker and such transfer agent will be instructed to debit such Performance Shares from the
Participant’s Account and return them to the Corporation. 
 (iv) Each book entry relating to Performance Shares may
otherwise include such restrictive instructions in such forms as the Corporation may deem convenient, expedient, necessary or appropriate relating to the restrictions under this Agreement, applicable securities, tax or other laws or applicable rules
of any securities exchange or market. 
 4.2 Transfer of Performance Shares. 
 (i) Unvested Performance Shares (including unvested Earned Shares) cannot be Transferred to any Person or entity for any purpose without
the prior written consent of the Corporation. Any attempt to effect a Transfer of unvested Performance Shares (including unvested Earned Shares) without such consent shall be null and void. 
 (ii) To the extent necessary (as determined by the Corporation) to permit resale by the Participant of vested Earned Shares, the
Corporation will use reasonable efforts to register the resale of such Earned Shares under the Securities Act, so long as the Corporation is permitted to do so on Form S-3 or S-8 or a similar abbreviated form and subject to the terms and conditions
set forth in the Plan and such other reasonable or customary terms and conditions as may be imposed by the Corporation (including those relating to indemnification by the Participant for errors or omissions from information provided by the
Participant). 
 4.3 Withholding Taxes. 
 (i) The Company shall withhold or deduct from any or all payments or amounts due to or held for the Participant, whether due from the Company or held in the Participant’s Account, an amount (the “Withholding
Amount”) equal to all taxes (including social security and Medicare, and other governmental charges of any kind, as well as income and other taxes) required to be withheld or deducted with respect to any and all taxable income and other amounts
attributable to the Performance Shares, including vested Earned Shares (the “Withholding Requirement”). Alternatively, the Participant may elect to pay the Withholding Amount in cash upon such terms and conditions as are acceptable to the
Company. 
  

 4 

 (ii) The Withholding Amount shall be determined by the Company. 
 (iii) The timing of withholding or deduction from such payments or amounts shall be determined by the Company; provided, however, that, if
such taxes are required to be paid to a tax or other governmental authority before such withholding or deduction is made, then the Company shall pay such taxes when due as agent for the Participant and shall be entitled to reimbursement therefor
from such payments or amounts, or otherwise. 
 (iv) The Corporation may restrict transfer of any or all vested Earned Shares
until all Withholding Requirements are satisfied. 
 (v) Unless the Participant has made or makes a timely election pursuant
to Section 83(b) of the Code or has paid the Withholding Amount in cash as provided above, the Participant authorizes the Corporation and the Broker to: 
 (A) sell, on his or her behalf and for his or her account, from time to time and at any time as the Corporation or the Broker may deem
necessary, appropriate, convenient or expedient to satisfy each Withholding Requirement or to reimburse the Company in respect thereof, a sufficient number of vested Earned Shares (as determined by the Corporation or the Broker) so that the net
proceeds from such sale equal or exceed the applicable Withholding Amount; and 
 (B) use the net proceeds to satisfy such
Withholding requirement (with any excess net proceeds to be paid to or deposited in an account of the Participant). 
 (vi) If
the Participant has made or makes an election pursuant to Section 83(b) of the Code, he or she shall immediately file a copy thereof with the Company and upon demand by the Company make a cash payment to the Company equal to any Withholding
Amount in respect thereof. 
 (vii) In connection with any sale of vested Earned Shares pursuant to this Section 4.3, the
Participant agrees that: 
 (A) such sale may be aggregated with sales of restricted stock, performance shares or other
securities granted to other participants under the Plan or other plans of the Company; 
 (B) such aggregated sales may be
made from time to time in one or more installments at any time; 
 (C) such aggregated sales may be made over time as the
Corporation or the Broker may deem necessary, appropriate, convenient or expedient, with a view toward avoidance or minimization of disruption of the market for the Common Stock, administrative convenience, minimization of costs and expenses or
other factors; and 
  

 5 

 (D) the net proceeds from such aggregated sales and the sale prices of the shares sold
may be allocated among such vested Earned Shares and other performance shares, restricted stock and other securities and the Participant and such other participants as the Corporation or the Broker may deem reasonable. 
 (viii) The Participant understands that: 
 (A) different Withholding Requirements may arise at different times based on time of delivery or vesting of Performance Shares, tax elections or other factors; 
 (B) different Withholding Requirements may be based on different values attributable to Performance Shares at such times or otherwise
based on applicable tax laws, changes in the financial performance or prospects of the Company, changes in market or economic conditions or other factors; 
 (C) it may not be practicable or permissible to sell vested Earned Shares to satisfy each Withholding Requirement at the time due because of rules and requirements of the Broker, administrative rules and requirements
of the Company, restrictions under the Company’s insider trading and other compliance policies and procedures, potential liability for short-swing profits under Section 16(b) of the Exchange Act, applicable securities, tax or other laws,
applicable rules of any securities exchange or market, or other factors; and 
 (D) as a result, vested Earned Shares may be
sold at times and values that differ, potentially significantly, from those applicable to such Withholding Requirement and that such differences can result in gains or losses, potentially significant, relative to those values and capital gains and
losses for tax purposes in addition to the taxes described in Section 4.3(i). 
 (ix) The Participant hereby appoints
each officer and assistant officer of the Corporation to be the Participant’s true and lawful agent, proxy and attorney-in-fact, with full power of substitution and re-substitution (each, an “attorney-in-fact” and, together, the
“attorneys-in-fact”), to take, cause to be taken and authorize the taking of any and all actions (including the giving of instructions to sell and the approval of confirmations), to incur, cause to be incurred and authorize the incurrence
of any and all costs and expenses (including brokerage commissions), to undertake, cause to be undertaken and authorize the undertaking of any and all obligations and to execute, acknowledge, file, publish and deliver, cause to be executed,
acknowledged, filed, published and delivered and authorize the execution, acknowledgement, filing, publication and delivery of any and all agreements, instruments and documents (including stock powers, account agreements and related documents, and
wire transfer instructions) which any such attorney-in-fact may deem necessary, appropriate, convenient or expedient to sell vested earned Shares, on behalf and for the account of the Participant, to generate net proceeds to satisfy any and all
Withholding Requirements, to use net proceeds in satisfaction thereof and to otherwise give effect to the intent and purposes of this Section 4.3, all in the name of the Participant, any such attorney-in-fact, the Corporation or any Subsidiary
and all at such times, in such manners, in such amounts, on such exchanges or markets, on such terms, through such brokers, dealers and accounts and otherwise as any such attorney-in-fact may determine in his or her sole and absolute discretion, and
hereby grants to each attorney-in-fact the full power and authority to do any and all things necessary, convenient, expedient or appropriate in connection therewith. This power of attorney shall not be affected in any manner by reason of the
execution, at any time, of other powers of attorney by the Participant in favor of persons other than the attorneys-in-fact named herein and shall not be affected by the subsequent death, disability or incompetence of the Participant. This power of
attorney is irrevocable and coupled with an interest and shall remain in effect until all Withholding Requirements have been fully and unconditionally satisfied. All persons dealing with any of the attorneys-in-fact may assume that this power of
attorney has not been revoked and may be relied upon. 
  

 6 

 (x) The Participant acknowledges and agrees that neither the Company, the Broker nor any
of their respective affiliates, control persons, directors, officers, employees, representatives or agents shall have any liability or obligation for any losses, damages, costs or expenses of any kind or under any theory arising out of or in
connection with any action taken or omitted to be taken or any delay in taking any action pursuant to or contemplated by this Section 4.3 (including the determination of any Withholding Amount or the time when any Withholding Requirement is
required to be satisfied or any sale of or delay in selling or failure to sell or the price, terms or conditions of sale of any or all of the vested Earned Shares), including any liability for any claim that the Participant could have made more or
lost less in connection therewith or for any capital gain or loss due to the difference in time between the triggering of a Withholding Requirement and the resale of vested Earned Shares in respect thereof or for violations of insider trading or
other laws or for incurrence of liability for short-swing profits under Section 16(b) of the Exchange Act, except to the extent that a court of competent jurisdiction determines by final and non-appealable judgment that any such losses,
damages, costs or expenses resulted from actions taken or omitted to be taken by them in bad faith or from their gross negligence or willful misconduct. References in this Section 4.3 to “selling” and correlative terms include all
activities related thereto, including placement and execution of sell orders, selection of brokers and dealers, delivery of share certificates, receipt of proceeds and payment of fees and commissions. 
 (xi) The provisions hereof regarding sale of vested Earned Shares to satisfy Withholding Requirements are also intended to constitute a
trading plan within the meaning of Rule 10b5-1 under the Securities Act. 
 (xii) The Participant accepts this Agreement and
the Performance Shares subject to, and agrees to assume, the limitations, risks and responsibilities inherent with respect to the Performance Shares, including those mentioned in this Agreement. 
 ARTICLE V 
 FORFEITURE

 Notwithstanding anything contained herein to the contrary, if the Participant engages in Detrimental Conduct, then the Compensation
Committee or the Board shall have the right, in its sole and good faith judgment, to change the basis or timing on which any or all Performance Shares become Earned Shares, suspend (temporarily or permanently) the vesting of any or all of the
unvested Earned Shares, extend the date for such vesting, suspend (temporarily or permanently) the Transferability of any or all of the vested Earned Shares, require the forfeiture of any or all of the Performance Shares (including vested Earned
Shares) then held by the Participant or his affiliates or related parties, or take any other actions in respect of any or all of the Performance Shares or this Agreement; provided, that any change to the terms of the Performance Shares shall be
effected in a way that causes the Performance Shares to be excluded from the application of, or to comply with, Section 409A. 
  

 7 

 ARTICLE VI 
 RESTRICTED ACTIVITIES 
 6.1 From the effective date of this Agreement and for a period of two
(2) years following (a) voluntary termination of Participant’s employment with the Company or (b) involuntary termination of Participant’s employment with the Company for Cause or Detrimental Conduct, Participant agrees to
the following: 
 (i) The Participant agrees that the Participant shall not, without the Company’s prior written consent,
directly or indirectly, either for himself or herself or on behalf of any other corporation, partnership, company, person, group, or entity, engage in the business of (i) manufacturing, distributing, selling or providing carbon or graphite
products, services, material or equipment of the kind or type which are the same as or similar to those manufactured, distributed, or sold by the Company now or in the future while the Participant is an employee of the Company, or (ii) any
other business in which the Company directly or indirectly engages now or in the future while the Participant is an employee of the Company. For purposes of this Article VI, the Participant shall be deemed to “engage in the business”
if he or she, directly or indirectly, engages or invests in, owns, manages, operates, controls or participates in the ownership, management, operation or control of, is employed by, associated or connected in any manner with, or renders services or
advice to, any corporation, partnership, company, person, group or entity engaged in the activities identified above; provided, however, that the Participant may invest in the securities of any enterprise (but without otherwise participating in the
activities of such enterprise) if (x) such securities are listed on any international, national or regional securities exchange or market or have been registered under Section 12(g) of the Securities Exchange Act of 1934 and (y) the
Participant does not beneficially own (as defined under Rule 13d-3 promulgated under the Securities Exchange Act of 1934) in excess of 5% of the outstanding equity thereof (provided, that the Participant shall be deemed not to beneficially own
any securities owned by a registered or unregistered investment company with more than $50 million under management). 
 (ii)
The provisions set forth in Section 6.1(i) shall apply only to the reasonable and limited geographic area consisting of (i) any state, country, possession, or territory in which the Company directly or indirectly has offices, operations,
or customers, or otherwise conducts business; or (ii) during the Participant’s period of employment, any state, country, possession, or territory in which the Company plans to conduct business. 
 (iii) The Participant shall not, directly or indirectly, call on, solicit or take away any of the customers or potential customers of the
Company on whom the Participant called or with whom the Participant became acquainted or of which the Participant learned during employment with the Company. 
 (iv) The Participant shall not, directly or indirectly, solicit for employment any employee of the Company or encourage, induce, attempt
to induce, or assist another to induce or attempt to induce any employee of the Company to terminate his or her employment with the Company. 
 (v) The Participant shall not interfere, in any manner, with the business, trade, goodwill, sources of supply, or customers of the Company. The Participant shall refrain from making any statements or comments of a
defamatory or disparaging nature to any third party regarding the Company, or any of the Company’s officers, directors, policies or products, other than to comply with any law or court, regulatory or governmental investigatory order on request.

  

 8 

 (vi) The Participant agrees that if a court of competent jurisdiction determines that the
length of time, geographic scope or other restrictions, or portion thereof, set forth in this Article VI is overly restrictive and unenforceable, the court may reduce or modify the same to the maximum limitations permitted by law, and as so reduced
or modified, the parties hereto agree that the restrictions of this Article VI shall remain in full force and effect. The Participant further agrees that if a court of competent jurisdiction determines that any provision of this Article VI is
invalid or against public policy, the remaining provisions of this Article VI and the remainder of this Agreement shall not be affected thereby, and shall remain in full force and effect. 
 (vii) The Participant acknowledges that the business of the Company is international in scope and that the restrictions imposed by this
Agreement are legitimate, reasonable and necessary to protect the Company’s investment in its businesses and the goodwill thereof. The Participant acknowledges that the scope and duration of the restrictions contained herein are reasonable in
light of the time that the Participant has been engaged in the business of the Company, the Participant’s reputation in the markets for the Company’s and the Participant’s relationship with the suppliers and customers of the Company.
The Participant further acknowledges that the restrictions contained herein are not burdensome to the Participant in light of the grant of the Performance Shares hereunder. Moreover, the Participant acknowledges that he or she has other means
available to him or her for the pursuit of his or her livelihood. Except as otherwise provided herein, this Article VI shall survive the termination of this Agreement. 
 6.2 The Participant acknowledges that in the event of any violation by the Participant of the provisions set forth in this Article VI, the Company
will sustain serious, irreparable and substantial harm to its business, the extent of which will be difficult to determine and impossible to fully remedy by an action at law for money damages. Accordingly, the Participant agrees that, in the event
of such violation or threatened violation by the Participant, the Company shall be entitled to an injunction before trial by any court of competent jurisdiction as a matter of course, in addition to all such other legal and equitable remedies as may
be available to the Company. The Participant agrees that no bond needs to be furnished for such injunctive relief. If the Company is required to enforce the provisions set forth in this Article VI by seeking an injunction, the Participant
agrees that the relevant time periods set forth in this Article VI shall commence with the entry of the injunction. In addition to any and all of the rights and remedies which the Company may have against the Participant, the Participant will
be liable to and pay the Company its court costs and reasonable attorneys’ fees incurred in enforcing the Participant’s covenants hereunder.

Company or any of its Restricted Subsidiaries Incurs, repays, repurchases or redeems any Indebtedness (other than in the case of revolving credit borrowings or revolving advances under any Qualified Receivables Financing, in which case interest
expense shall be computed based upon the average daily balance of such Indebtedness during the applicable period) or issues, repurchases or redeems Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the
Fixed Charge Coverage Ratio is being calculated but prior to the event for which the calculation of the Fixed Charge Coverage Ratio is made (the “Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma
effect to such Incurrence, repayment, repurchase or redemption of Indebtedness, or such issuance, repurchase or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period.

 For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and

after the Issue Date and during the four-quarter reference period or subsequent 

  

 15 

 
to such reference period and on or prior to or simultaneously with the Calculation Date (each, for purposes of this definition, a “pro forma
event”) shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, consolidations (including the Apollo Transactions), discontinued operations and operational changes (and the change of any
associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary
or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation, discontinued operation or operational change, in each case with
respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition,
disposition, discontinued operation, merger, consolidation or operational change had occurred at the beginning of the applicable four-quarter period. 
 For purposes of this definition, whenever pro forma effect is to be given to any pro forma event, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Company.
Any such pro forma calculation may include adjustments appropriate, in the reasonable good faith determination of the Issuers as set forth in an Officers’ Certificate, to reflect (1) operating expense reductions and other operating
improvements or synergies reasonably expected to result from the applicable pro forma event (including, to the extent applicable, from the Apollo Transactions), and (2) all adjustments of the nature used in connection with the calculation of
“Adjusted EBITDA” as set forth in footnote 3 to the “Summary Historical and Unaudited Pro Forma Financial Data” under “Offering Circular Summary” in the July 2006 Offering Circular to the extent such adjustments,
without duplication, continue to be applicable to such four-quarter period. 
 If any Indebtedness bears a floating rate of interest and is
being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such
Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of
the Company to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro
forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a
eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuers may designate. 
 “Fixed Charges” means, with respect to any Person for any period, the sum, without duplication, of: 
 (1) Consolidated Interest Expense of such Person for such period, and

series of Preferred Stock or Disqualified Stock of such Person and its Restricted Subsidiaries.

Principles Board of the American Institute of Certified Public Accountants and statements and pronouncements of the Financial Accounting Standards Board or in such other statements by such other entity as have been approved by a significant segment
of the accounting profession, which are in effect on the Issue Date. For the purposes of this Indenture, the term “consolidated” with respect to any Person shall mean such Person consolidated with its Restricted Subsidiaries, and shall not
include any Unrestricted Subsidiary, but the interest of such Person in an Unrestricted Subsidiary will be accounted for as an Investment. 
 “Guarantee” means any guarantee of the obligations of the Company under this Indenture and the Securities by any Person in accordance with the provisions of this Indenture. 
 “guarantee” means a guarantee (other than by endorsement of negotiable instruments for collection in the ordinary course of business), direct

 (1) the principal and premium (if any) of any indebtedness of such Person, whether or not contingent, (a) in respect of borrowed

purchase price of any property, except any such balance that constitutes a trade payable or similar obligation to a trade creditor due within six months from the date on which it is Incurred, in each case Incurred in the ordinary course of business,
which purchase price is due more than six months after the date of placing the property in service or taking delivery and title thereto, (d) in respect of Capitalized Lease Obligations, or (e) representing any Hedging Obligations, if and
to the extent that any of the foregoing indebtedness (other than letters of credit and Hedging Obligations) would appear as a liability on a balance sheet (excluding the footnotes thereto) of such Person prepared in accordance with GAAP;

 Notwithstanding anything in this Indenture to the contrary, Indebtedness
shall not include, and shall be calculated without giving effect to, the effects of Statement of Financial Accounting Standards No. 133 and related interpretations to the extent such effects would otherwise increase or decrease an amount of
Indebtedness for any purpose under this Indenture as a result of accounting for any embedded derivatives created by the terms of such Indebtedness; and any such amounts that would have constituted Indebtedness under this Indenture but for the
application of this sentence shall not be deemed an Incurrence of Indebtedness under this Indenture.

denomination. 
  

 36

in an unlimited principal amount, so long as (i) the Incurrence of the Indebtedness represented by such Additional Securities is at such time permitted by Section 4.03 and (ii) such Additional Securities are issued in compliance with
the other applicable provisions of this Indenture. With respect to any Additional Securities issued after the Closing Date (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other
Securities pursuant to Section 2.07, 2.08, 2.09, 2.10, 3.06, 4.06(g), 4.08(c) or the Appendix), there shall be (a) established in or pursuant to a resolution of the Board of Directors and (b) (i) set forth or determined in the
manner provided in an Officers’ Certificate or (ii) established in one or more indentures supplemental hereto, prior to the issuance of such Additional Securities: 
 (1) the aggregate principal amount of such Additional Securities which may be authenticated and delivered under this Indenture;

 (2) the issue price and issuance date of such Additional Securities, including the date from which interest on such
Additional Securities shall accrue; 
 (3) if applicable, that such Additional Securities shall be issuable in whole or in
part in the form of one or more Global Securities and, in such case, the respective depositaries for such Global Securities, the form of any legend or legends which shall be borne by such Global Securities in addition to or in lieu of those set
forth in Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Section 2.2 of the Appendix in which any such Global Security may be exchanged in whole or in part for Additional Securities registered, or any
transfer of such Global Security in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Security or a nominee thereof; and 
 (4) if applicable, that such Additional Securities that are not Transfer Restricted Securities shall not be issued in the form of Initial
Securities as set forth in Exhibit A, but shall be issued in the form of Exchange Securities as set forth in Exhibit B. 
 If any of the
terms of any Additional Securities are established by action taken pursuant to a resolution of the Board of Directors, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or the indenture supplemental hereto setting forth the terms of the Additional Securities. 
 The Securities, including any Additional Securities, shall be treated as a single class for all purposes under this Indenture, including, without
limitation, directions provided to the Trustee pursuant to section 6.05, waivers, amendments, redemptions and offers to purchase. 
 SECTION
2.02. Form and Dating. Provisions relating to the Initial Securities and the Exchange Securities are set forth in the Appendix, which is hereby incorporated in and expressly made a part of this Indenture. The (i) Initial Securities and
the Trustee’s certificate of authentication and (ii) any Additional Securities (if issued as Global Securities or Transfer Restricted Definitive Securities) and the Trustee’s certificate of authentication shall each be 

  

 37 

 
substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The (i) Exchange Securities
and the Trustee’s certificate of authentication and (ii) any Additional Securities issued other than as Transfer Restricted Securities and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit
B hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company or any Guarantor is subject, if
any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The Securities shall be issuable only in registered form without
interest coupons and in denominations of $2,000 and any integral multiples of $1,000. 
 SECTION 2.03. Execution and Authentication.
The Trustee shall authenticate and make available for delivery upon a written order of the Company signed by one Officer (a) Original Securities for original issue on the date hereof in an aggregate principal amount of $196,270,000
(b) subject to the terms of this Indenture, Additional Securities in an aggregate principal amount to be determined at the time of issuance and specified therein and (c) the Exchange Securities for issue in a Registered Exchange Offer
pursuant to the Registration Agreement for a like principal amount of Initial Securities exchanged pursuant thereto or otherwise pursuant to an effective registration statement under the Securities Act. Such order shall specify the amount of the
Securities to be authenticated, the date on which the original issue of Securities is to be authenticated and whether the Securities are to be Initial Securities or Exchange Securities. Notwithstanding anything to the contrary in the Indenture or
the Appendix, any issuance of Additional Securities after the Closing Date shall be in a principal amount of at least $2,000 and integral multiples of $1,000 in excess of $2,000. 
 One Officer shall sign the Securities for each Issuer by manual or facsimile signature. 
 If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless. 
 A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of
authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 The Trustee may appoint one or more authenticating agents reasonably acceptable to the Issuers to authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be
furnished to each Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication
by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 
 SECTION 2.04. Registrar and Paying Agent. (a) The Company shall maintain (i) an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an
office or agency where Securities may be presented for 

  

 38 

 
payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or
more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Company initially appoints the
Trustee as Registrar, Paying Agent and the Securities Custodian with respect to the Global Securities. 
 (b) The Company may enter into an
appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically organized Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 
 (c) The Company may remove
any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a
successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as
Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Company and the Trustee; provided, however, that
the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08. 
 (d)
Except as the Company and the Trustee may agree otherwise agree, the Company shall promptly file with the Trustee following the end of each calendar year a written notice specifying the amount of original issue discount accrued on the Outstanding
Securities for the previous calendar year, including daily rates and accrual periods, and such other information relating to original issue discount as may be required under the Internal Revenue Code of 1986 and applicable regulations, as amended
from time to time. 
 SECTION 2.05. Paying Agent to Hold Money in Trust. Prior to each due date of the principal of and interest on
any Security, the Company shall deposit with each Paying Agent (or if the Company or a Wholly Owned Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such
principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by a Paying Agent
for the payment of principal of and interest on the Securities, and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Wholly Owned Subsidiary of the Company acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed
by such Paying Agent. Upon complying with this Section, a Paying Agent shall have no further liability for the money delivered to the Trustee. 
  

 39 

 SECTION 2.06. Holder Lists. The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before
each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders. 
 SECTION 2.07. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer and in compliance with the Appendix. When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are
met. When Securities are presented to the Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit
registration of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. The Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental
charges in connection with any transfer or exchange pursuant to this Section. The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of
Securities to be redeemed in part, the portion thereof not to be redeemed) or of any Securities for a period of 15 days before a selection of Securities to be redeemed. 
 Prior to the due presentation for registration of transfer of any Security, the Company, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company,
any Guarantor, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 
 Any Holder of a beneficial
interest in a Global Security shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by (a) the Holder of such Global
Security (or its agent) or (b) any Holder of a beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required to be reflected in a book entry. 
 All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the
same benefits under this Indenture as the Securities surrendered upon such transfer or exchange. 
 SECTION 2.08. Replacement
Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Company or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful
taking and the Registrar does not register 

  

 40 

 
a transfer prior to receiving such notification, (b) makes such request to the Company or the Trustee prior to the Security being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder
shall furnish an indemnity bond sufficient in the judgment of the Trustee or the Company to protect the Issuers, each Guarantor, the Trustee, a Paying Agent and the Registrar from any loss that any of them may suffer if a Security is replaced. The
Company and the Trustee may charge the Holder for their expenses in replacing a Security (including without limitation, attorneys’ fees and disbursements in replacing such Security). In the event any such mutilated, lost, destroyed or
wrongfully taken Security has become or is about to become due and payable, the Company in its discretion may pay such Security instead of issuing a new Security in replacement thereof. 
 Every replacement Security is an additional obligation of the Company. 
 The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully
taken Securities. 
 SECTION 2.09. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Subject to Section 13.06, a Security does not cease to be outstanding because the Company or an Affiliate of
the Company holds the Security. 
 If a Security is replaced pursuant to Section 2.08 (other than a mutilated Security surrendered for
replacement), it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser. A mutilated Security ceases to be outstanding upon surrender of such
Security and replacement thereof pursuant to Section 2.08. 
 If a Paying Agent segregates and holds in trust, in accordance with this
Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is
prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 
 SECTION 2.10. Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such
Definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Securities and make them available for delivery in exchange for temporary Securities upon surrender
of such temporary Securities at the office or agency of the Company, without charge to the Holder. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as Definitive Securities. 
  

 41 

 SECTION 2.11. Cancellation. The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and each Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities surrendered for registration
of transfer, exchange, payment or cancellation and shall dispose of canceled Securities in accordance with its customary procedures. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for
cancellation. The Trustee shall not authenticate Securities in place of canceled Securities other than pursuant to the terms of this Indenture. 
 SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay the defaulted interest then borne by the Securities (plus interest on such defaulted interest to the extent
lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date and shall promptly
mail or cause to be mailed to each affected Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. The special record date for the payment of such defaulted interest shall not be more
than 15 days and not less than 10 days prior to the proposed payment date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. 
 SECTION 2.13. CUSIP Numbers, ISINs, etc. The Issuers in issuing the Securities may use CUSIP numbers, ISINs and “Common Code” numbers
(if then generally in use) and, if so, the Trustee shall use CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers, either as printed on the Securities or as contained in any notice of a redemption that reliance may be placed only on the other identification numbers printed on the Securities and that
any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers shall advise the Trustee of any change in the CUSIP numbers, ISINs and “Common Code” numbers. 
 SECTION 2.14. Calculation of Principal Amount of Securities. The aggregate principal amount of the Securities, at any date of determination, shall
be the principal amount of the Securities at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the Securities, such
percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Securities, the Holders of which have so consented, by (b) the aggregate principal amount, as
of such date of determination, of the Securities then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.09 and Section 13.06 of this Indenture. Any such calculation made pursuant to this
Section 2.14 shall be made by the Company and delivered to the Trustee pursuant to an Officers’ Certificate. 
  

 42 

 ARTICLE 3 
 REDEMPTION 
 SECTION 3.01. Redemption. The Securities may be redeemed, in whole, or from time
to time in part, subject to the conditions and at the redemption prices set forth in Paragraph 5 of the form of Securities set forth in Exhibit A and Exhibit B hereto, which are hereby incorporated by reference and made a part of this Indenture,
together with accrued and unpaid interest to the redemption date. 
 SECTION 3.02. Applicability of Article. Redemption of Securities
at the election of the Company or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article. 
 SECTION 3.03. Notices to Trustee. If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraph 5 of the
Security, it shall notify the Trustee in writing of (i) the Section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Securities to be redeemed and (iv) the
redemption price. The Company shall give notice to the Trustee provided for in this paragraph at least 30 days but not more than 60 days before a redemption date if the redemption is pursuant to Paragraph 5 of the Security, unless a shorter period
is acceptable to the Trustee. Such notice shall be accompanied by an Officers’ Certificate and Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein. If fewer than all the Securities are
to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which record date shall be not fewer than 15 days after the date of notice to the Trustee. Any such notice may be canceled at any
time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect. 
 SECTION 3.04. Selection
of Securities to Be Redeemed. In the case of any partial redemption, and if the Securities are Global Securities (as defined in Appendix A) held by the Depository (as defined in Appendix A), the Depository will select the Securities to be
redeemed in accordance with its operational arrangements. If the Securities are not Global Securities held by the Depository, selection of the Securities for redemption will be made by the Trustee on a pro rata basis to the extent practicable;
provided that no Securities of $2,000 or less shall be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of
Securities that have denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in amounts of $2,000 or any integral multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed. 
 SECTION 3.05. Notice of Optional Redemption. (a) At least 30 days but not more than 60 days before a redemption date pursuant to Paragraph 5
of the Security, the Company shall mail or cause to be mailed by first-class mail a notice of redemption to each Holder whose Securities are to be redeemed. 
  

 43 

 Any such notice shall identify the Securities to be redeemed and shall state: 
 (i) the redemption date; 
 (ii) the redemption price and the amount of accrued interest to the redemption date; 
 (iii)
the name and address of the Paying Agent; 
 (iv) that Securities called for redemption must be surrendered to the Paying
Agent to collect the redemption price, plus accrued interest; 
 (v) if fewer than all the outstanding Securities are to be
redeemed, the certificate numbers and principal amounts of the particular Securities to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial
redemption; 
 (vi) that, unless the Company defaults in making such redemption payment or the Paying Agent is prohibited from
making such payment pursuant to the terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date; 
 (vii) the CUSIP number, ISIN and/or “Common Code” number, if any, printed on the Securities being redeemed; and 
 (viii) that no representation is made as to the correctness or accuracy of the CUSIP number or ISIN and/or “Common Code” number,
if any, listed in such notice or printed on the Securities. 
 (b) At the Company’s request, the Trustee shall give the notice of
redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section at least five Business Days (unless the Trustee consents to a shorter period)
prior to the date such notice is to be provided to Holders and such notice may not be canceled. 
 SECTION 3.06. Effect of Notice of
Redemption. Once notice of redemption is mailed in accordance with Section 3.05, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, except as provided in the
final sentence of paragraph 5 of the Securities. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest, to, but not including, the redemption date; provided,
however, that if the redemption date is after a regular record date and on or prior to the interest payment date, the accrued interest shall be payable to the Holder of the redeemed Securities registered on the relevant record date. Failure
to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 
 SECTION 3.07.
Deposit of Redemption Price. With respect to any Securities, prior to 10:00 a.m., New York City time, on the redemption date, the Company shall deposit 

  

 44 

 
with the Paying Agent (or, if the Company or a Wholly Owned Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the
redemption price of and accrued interest on all Securities or portions thereof to be redeemed on that date other than Securities or portions of Securities called for redemption that have been delivered by the Company to the Trustee for cancellation.
On and after the redemption date, interest shall cease to accrue on Securities or portions thereof called for redemption so long as the Company has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid
interest on, the Securities to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture. 
 SECTION 3.08. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate for the Holder (at the Company’s expense) a new Security equal in
principal amount to the unredeemed portion of the Security surrendered.

SEC if the SEC does not permit such filing, in which event the Company shall make available such information to prospective purchasers of Securities, including by posting such reports on the primary website of the Company or its Subsidiaries in
addition to providing such information to the Trustee and the Holders, in each case within 15 days after the time the Company would be required to file such information with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act.

 (b) In the event that: 
 (i) the rules and regulations of the SEC permit the Company and any direct or indirect parent of the Company to report at such parent entity’s level on a consolidated basis and 
 (ii) such parent entity of the Company is not engaged in any business in any material respect other than incidental to its ownership,
directly or indirectly, of the capital stock of the Company, 
 such consolidated reporting at such parent entity’s level in a manner
consistent with that described in this Section 4.02 for the Company shall satisfy this Section 4.02. 
 (c) The
Company shall make such information available to prospective investors upon request. In addition, the Company shall, for so long as any Securities remain outstanding during any period when it is not subject to Section 13 or 15(d) of the

Securities, the Company may satisfy its obligations under this Section 4.02 with respect to financial information relating to the Company by furnishing financial information relating to such direct or indirect parent; provided that the
same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such direct or indirect parent and any of its Subsidiaries other than the Company and its Subsidiaries, on the
one hand, and the information relating to the Company, the Guarantors and the other Subsidiaries of the Company on a stand-alone basis, on the other hand.

preceding the date on which such additional Indebtedness is Incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.00 to 1.00 determined on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been Incurred, or the Disqualified Stock or Preferred Stock had been issued, as the case may be, and the application of proceeds therefrom had occurred at the beginning of such four-quarter period.

which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an

Incurred such Indebtedness under Section 4.03(a) without reliance upon this clause (xii));

fees and expenses Incurred in connection with such refinancing; 
 (5) shall not include (x) Indebtedness of a
Restricted Subsidiary of the Company that is not a Guarantor that refinances Indebtedness of the Company or a Restricted Subsidiary that is a Guarantor, or (y) Indebtedness of the Company or a Restricted Subsidiary that refinances Indebtedness

(xiv) for purposes of determining amounts outstanding under such clauses (iv) or (xix) of this Section 4.03(b); 
 provided, further, that subclauses (1) and (2) of this clause (xiv) shall not apply to any refunding or refinancing of any Bank Indebtedness;

Undertakings); 
 (xvii) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or
similar instrument drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days of its Incurrence;

 (xxii) Indebtedness consisting of customary indemnification, adjustment of purchase price
or similar obligations of the Company or any Restricted Subsidiary, in each case Incurred in connection with the acquisition or disposition of any assets by the Company or any Restricted Subsidiary. 
 For purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock
meets the criteria of more than one of the categories of permitted Indebtedness described in clauses (i) through (xxii) above or is entitled to be Incurred pursuant to Section 4.03(a), the Issuers shall, in their sole discretion,
classify or reclassify, or later divide, classify or reclassify, such item of Indebtedness in any manner that complies with this Section 4.03; provided that all Indebtedness under the Credit Agreement outstanding on the Issue Date shall
be deemed to have been Incurred pursuant to clause (i) of Section 4.03(b) and the Issuers shall not be permitted to reclassify all or any portion of such Indebtedness under the Credit Agreement outstanding on the Issue Date. Accrual of
interest, the accretion of accreted value, the payment of interest in the form of additional Indebtedness with the same terms, the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class,
accretion of original issue discount or liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies shall not be deemed to be an Incurrence of Indebtedness for
purposes of this Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included in the
determination of such amount of Indebtedness; provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03. 
 For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term debt, or first committed or first Incurred
(whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the
applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 
 SECTION 4.04. Limitation on Restricted Payments. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: 
 (i) declare or pay any dividend or make any distribution on account of the Company’s or any of its Restricted Subsidiaries’
Equity Interests, including any payment made in connection with any merger, amalgamation or consolidation involving the Company (other than (A) dividends or distributions by the Company payable solely in Equity Interests (other than
Disqualified Stock) of the Company; or (B) dividends or distributions by a Restricted Subsidiary so long as, in the case of any 

  

 52 

 
dividend or distribution payable on or in respect of any class or series of securities issued by a Restricted Subsidiary other than a Wholly Owned Restricted
Subsidiary, the Company or a Restricted Subsidiary receives at least its pro rata share of such dividend or distribution in accordance with its Equity Interests in such class or series of securities); 
 (ii) purchase or otherwise acquire or retire for value any Equity Interests of the Company or any direct or indirect parent of the
Company; 
 (iii) make any principal payment on, or redeem, repurchase, defease or otherwise acquire or retire for value, in
each case prior to any scheduled repayment or scheduled maturity, any Subordinated Indebtedness of the Company or any of its Restricted Subsidiaries (other than the payment, redemption, repurchase, defeasance, acquisition or retirement of
(A) Subordinated Indebtedness in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, redemption, repurchase, defeasance, acquisition or
retirement and (B) Indebtedness permitted under clauses (vii) and (ix) of Section 4.03(b)); or 
 (iv)
make any Restricted Investment 
 (all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as
“Restricted Payments”), unless, at the time of such Restricted Payment: 
 (1) no Default shall have occurred
and be continuing or would occur as a consequence thereof; 
 (2) immediately after giving effect to such transaction on a pro
forma basis, the Company could Incur $1.00 of additional Indebtedness under Section 4.03(a); and 
 (3) such Restricted
Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (including Restricted Payments permitted by clauses (i), (iv) (only to the extent of one-half
of the amounts paid pursuant to such clause), (vi) and (viii) of Section 4.04(b), but excluding all other Restricted Payments permitted by Section 4.04(b)), is less than the amount equal to the Cumulative Credit. 
 (b) The provisions of Section 4.04(a) shall not prohibit: 
 (i) the payment of any dividend or distribution within 60 days after the date of declaration thereof, if at the date of declaration such
payment would have complied with the provisions of this Indenture; 
 (ii) (A) the repurchase, retirement or other acquisition
of any Equity Interests (“Retired Capital Stock”) of the Company or any direct or indirect parent of the Company or Subordinated Indebtedness of the Company, any direct or indirect parent of the Company or any Guarantor in exchange for, or
out of the proceeds of, the substantially concurrent sale of, Equity Interests of the Company or any direct or 

  

 53 

 
indirect parent of the Company or contributions to the equity capital of the Company (other than any Disqualified Stock or any Equity Interests sold to a
Subsidiary of the Company or to an employee stock ownership plan or any trust established by the Company or any of its Subsidiaries) (collectively, including any such contributions, “Refunding Capital Stock”); and 
 (B) the declaration and payment of accrued dividends on the Retired Capital Stock out of the proceeds of the substantially concurrent
sale (other than to a Subsidiary of the Company or to an employee stock ownership plan or any trust established by the Company or any of its Subsidiaries) of Refunding Capital Stock; 
 (iii) the redemption, repurchase or other acquisition or retirement of Subordinated Indebtedness of the Company or any Guarantor made by

date of the Subordinated Indebtedness being so redeemed, repurchased, acquired or retired or (y) 91 days following the maturity date of the Securities, and 
 (D) such Indebtedness has a Weighted Average Life to Maturity at the time Incurred which is not less than the shorter of (x) the
remaining Weighted Average Life to Maturity of the Subordinated Indebtedness being so redeemed, repurchased, acquired or retired and (y) the Weighted Average Life to Maturity that would result if all payments of principal on the Subordinated
Indebtedness being redeemed, repurchased, acquired or retired that were due on or after the date one year following the last maturity date of any Securities then outstanding were instead due on such date one year following the last date of maturity
of the Securities; 
 (iv) the repurchase, retirement or other acquisition (or dividends to any direct or indirect parent of

and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such
designation shall only be permitted if a Restricted Payment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
  

 57

 (3) applicable law or any applicable rule, regulation or order;

 For purposes of determining compliance with this Section 4.05, (i) the priority of any Preferred Stock in receiving dividends or liquidating
distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability to make distributions on Capital Stock and (ii) the subordination of loans or advances made to the Company

 SECTION 4.06. Asset Sales. (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, cause or make an Asset Sale, unless (x) the Company or any of its Restricted Subsidiaries, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value (as
determined in good faith by the Issuers) of the assets sold or otherwise disposed of, and (y) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary, as the case may be, is in the form of Cash
Equivalents; provided that the amount of: 
 (i) any liabilities (as shown on the Company’s or such Restricted
Subsidiary’s most recent balance sheet or in the notes thereto) of the Company or any Restricted Subsidiary of the Company (other than liabilities that are by their terms subordinated to the Securities or any Guarantee) that are assumed by the
transferee of any such assets, 
 (ii) any notes or other obligations or other securities or assets received by the Company or
such Restricted Subsidiary of the Company from such transferee that are converted by the Company or such Restricted Subsidiary of the Company into cash within 180 days of the receipt thereof (to the extent of the cash received), and 
 (iii) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an
aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iii) that is at that time outstanding, not to exceed the greater of 3.0% of Total Assets and $35 million at the time
of the receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value) 
 shall be deemed to be Cash Equivalents for the purposes of this Section 4.06(a). 
 (b) Within 365 days after the Company’s or any Restricted Subsidiary of the Company’s receipt of the Net Proceeds of any Asset
Sale, the Company or such Restricted Subsidiary of the Company may apply the Net Proceeds from such Asset Sale, at its option: 
 (i) to repay Senior Indebtedness, Secured Indebtedness, including Indebtedness under the Credit Agreement (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto) or
Indebtedness of a Foreign Subsidiary or Pari Passu Indebtedness (provided that if the Company or any Guarantor shall so reduce Obligations under Pari Passu Indebtedness, the Company shall equally and ratably reduce Obligations under the
Securities by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional
Interest, if any, the pro rata principal amount of Securities) or Indebtedness of a Restricted Subsidiary that is not a Guarantor, in each case other than Indebtedness owed to the Company or an Affiliate of the Company, 
  

 60 

 (ii) to make an investment in any one or more businesses (provided that if such
investment is in the form of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Company), assets, or property or capital expenditures, in each case used or useful in a
Similar Business, or 
 (iii) to make an investment in any one or more businesses (provided that if such investment is in the
form of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Company), properties or assets that replace the properties and assets that are the subject of such Asset Sale.

 In the case of Sections 4.06(b)(ii) and (iii), a binding commitment shall be treated as a permitted application of the Net Proceeds from
the date of such commitment; provided that (x) such investment is consummated within 545 days after receipt by the Company or any Restricted Subsidiary of the Net Proceeds of any Asset Sale and (y) if such investment is not
consummated within the period set forth in subclause (x), the Net Proceeds not so applied will be deemed to be Excess Proceeds (as defined below). 
 Pending the final application of any such Net Proceeds, the Company or such Restricted Subsidiary of the Company may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Proceeds in Cash
Equivalents or Investment Grade Securities. Any Net Proceeds from any Asset Sale that are not applied as provided and within the time period set forth in the first sentence of this Section 4.06(b) (it being understood that any portion of such
Net Proceeds used to make an offer to purchase Securities, as described in clause (i) of this Section 4.06(b), shall be deemed to have been invested whether or not such offer is accepted) shall be deemed to constitute “Excess
Proceeds.” When the aggregate amount of Excess Proceeds exceeds $15 million, the Issuers shall make an offer to all Holders of Securities (and, at the option of the Issuers, to holders of any Pari Passu Indebtedness) (an “Asset Sale
Offer”) to purchase the maximum principal amount of Securities (and such Pari Passu Indebtedness), that is at least $2,000 and an integral multiple of $1,000 that may be purchased out of the Excess Proceeds at an offer price in cash in an
amount equal to 100% of the principal amount thereof (or, in the event such Pari Passu Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest and Additional Interest,
if any (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness), to the date fixed for the closing of such offer, in accordance with the procedures set forth in
this Section 4.06. The Issuers shall commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceeds $15 million by mailing the notice required pursuant to the terms of
Section 4.06(f), with a copy to the Trustee. To the extent that the aggregate amount of Securities (and such Pari Passu Indebtedness) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuers may use any remaining
Excess Proceeds for general corporate purposes. If the aggregate principal amount of Securities (and such Pari Passu Indebtedness) surrendered by holders thereof exceeds the amount of Excess Proceeds, the Securities to be purchased shall be selected
in the manner described in Section 4.06(e). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 
  

 61 

 (c) The Issuers shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Indenture, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 
 (d) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided above, the Company shall deliver to
the Trustee an Officers’ Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the compliance of such
allocation with the provisions of Section 4.06(b). On such date, the Company shall also irrevocably deposit with the Trustee or with a paying agent (or, if the Company or a Wholly Owned Restricted Subsidiary is acting as the Paying Agent,
segregate and hold in trust) an amount equal to the Excess Proceeds to be invested in Cash Equivalents, as directed in writing by the Company, and to be held for payment in accordance with the provisions of this Section 4.06. The deposit of
such funds may be invested in the Wells Fargo Advantage Money Market Fund until such written investment instruction is received by the Trustee. Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer
Period”), the Company shall deliver to the Trustee for cancellation the Securities or portions thereof that have been properly tendered to and are to be accepted by the Company, along with a written payment and cancellation order. The Trustee
(or the Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering Holder in the amount of the purchase price as determined by the Company and stated in the written payment and cancellation order. In
the event that the Excess Proceeds delivered by the Company to the Trustee are greater than the purchase price of the Securities tendered, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period for
application in accordance with Section 4.06. 
 (e) Holders electing to have a Security purchased shall be required to surrender the
Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Trustee or the Company
receives not later than one Business Day prior to the Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered by the Holder for purchase and a
statement that such Holder is withdrawing his election to have such Security purchased. If at the end of the Offer Period more Securities (and such Pari Passu Indebtedness) are tendered pursuant to an Asset Sale Offer than the Issuers are required
to purchase, and if the Securities are Global Notes held by the Depository, the Depository will select the Securities to be redeemed in accordance with its operational arrangements. If the Securities are not Global Notes held by the Depository,
selection of such Securities for purchase shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Securities are listed, or if such Securities are not so listed, on a pro
rata basis, by lot or by 

  

 62 

 
such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that no
Securities of $2,000 or less shall be purchased in part. Selection of such Pari Passu Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness. 
 (f) Notices of an Asset Sale Offer shall be mailed by first-class mail, postage prepaid, at least 30 but not more than 60 days before the purchase date to each Holder of Securities at such Holder’s registered
address. If any Security is to be purchased in part only, any notice of purchase that relates to such Security shall state the portion of the principal amount thereof that has been or is to be purchased. 
 SECTION 4.07. Transactions with Affiliates. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of transactions, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $7.5 million, unless:

 (i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20 million, the Company delivers to the Trustee a resolution adopted in good
faith by the majority of the Board of Directors of the Company, approving such Affiliate Transaction and set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (i) above. 
 (b) The provisions of Section 4.07(a) shall not apply to the following: 
 (i)(A) transactions between or among the Company and/or any of its Restricted Subsidiaries and (B) any merger of the Company and any
direct parent of the Company; provided that such parent shall have no material liabilities and no material assets other than cash, Cash Equivalents and the Capital Stock of the Company and such merger is otherwise in compliance with the terms
of this Indenture and effected for a bona fide business purpose; 
 (ii) Restricted Payments permitted by Section 4.04
and Permitted Investments; 
 (iii)(x) the entering into of any agreement (and any amendment or modification of any such
agreement) to pay, and the payment of, annual management, consulting, monitoring and advisory fees to the Sponsors in an aggregate amount in any fiscal year not to exceed the greater of (A) $2.5 million and (B) 1.5% of EBITDA of the
Company and its Restricted Subsidiaries for the immediately preceding fiscal year, and out-of-pocket expense reimbursement; 

  

 63 

 
provided, however, that any payment not made in any fiscal year may be carried forward and paid in the following two fiscal years and (y) the
payment of the present value of all amounts payable pursuant to any agreement described in clause (iii)(x) of Section 4.07(b) in connection with the termination of such agreement; 
 (iv) the payment of reasonable and customary fees and reimbursement of expenses paid to, and indemnity provided on behalf of, officers,
directors, employees or consultants of the Company or any Restricted Subsidiary or any direct or indirect parent of the Company; 
 (v) payments by the Company or any of its Restricted Subsidiaries to the Sponsors made for any financial advisory, financing, underwriting or placement services or in respect of other investment banking activities, including, without
limitation, in connection with acquisitions or divestitures, which payments are (x) made pursuant to the agreements with the Sponsors described in the July 2006 Offering Circular or (y) approved by a majority of the Board of Directors of
the Company in good faith; 
 (vi) transactions in which the Company or any of its Restricted Subsidiaries, as the case may
be, delivers to the Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or meets the requirements of clause (i) of
Section 4.07(a); 
 (vii) payments or loans (or cancellation of loans) to employees or consultants which are approved by
a majority of the Board of Directors of the Company in good faith; 
 (viii) any agreement as in effect as of the Issue Date
or any amendment thereto (so long as any such agreement together with all amendments thereto, taken as a whole, is not more disadvantageous to the Holders of the Securities in any material respect than the original agreement as in effect on the
Issue Date) or any transaction contemplated thereby as determined in good faith by senior management or the Board of Directors of the Company; 
 (ix) the existence of, or the performance by the Company or any of its Restricted Subsidiaries of its obligations under the terms of, the Apollo Acquisition Documents, any stockholders agreement (including any

of, or the performance by the Company or any of its Restricted Subsidiaries of its obligations under, any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by
this clause (ix) to the extent that the terms of any such existing agreement together with all amendments thereto, taken as a whole, or new agreement are not otherwise more disadvantageous to the Holders of the Securities in any material
respect than the original agreement as in effect on the Issue Date; 
  

 64

of business and otherwise in compliance with the terms of this Indenture, which are fair to the Company and its Restricted Subsidiaries in the reasonable determination of the Board of Directors or the senior management of the Company, or are on

 (xiii) the issuance of Equity Interests (other than Disqualified Stock) of the Company to any Person;

right to require the Issuers to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to

the occurrence of a Change of Control, the Issuers shall not be obligated to purchase any Securities pursuant to this Section 4.08 in the event that they have exercised their right to redeem such Securities in accordance with Article 3 of this
Indenture. In the event that at the time of such Change of Control the terms of the Bank Indebtedness restrict or prohibit the repurchase of Securities pursuant to this Section 4.08, then prior to the mailing of the notice to the Holders
provided for in Section 4.08(b) but in any event within 30 days following any Change of Control, the Issuers shall (i) repay in full all Bank Indebtedness or, if doing so will allow the purchase of Securities, offer to repay in full all
Bank Indebtedness and repay the Bank Indebtedness of each lender who has accepted such offer, or (ii) obtain the requisite consent under the agreements governing the Bank Indebtedness to permit the repurchase of the Securities as provided for
in Section 4.08(b). 
 (b) Within 30 days following any Change of Control, except to the extent that the Issuers have exercised their
right to redeem the Securities in accordance with Article 3 of this Indenture, the Company shall mail a notice (a “Change of Control Offer”) to each Holder with a copy to the Trustee stating: 
 (i) that a Change of Control has occurred and that such Holder has the right to require the Issuers to repurchase such Holder’s
Securities at a repurchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to the date of repurchase (subject to the right of the Holders of record on the relevant record
date to receive interest on the relevant interest payment date); 
 (ii) the circumstances and relevant facts and financial
information regarding such Change of Control; 
 (iii) the repurchase date (which shall be no earlier than 30 days nor later
than 60 days from the date such notice is mailed); and 
 (iv) the instructions determined by the Issuers, consistent with
this Section 4.08, that a Holder must follow in order to have its Securities purchased. 
 (c) Holders electing to have a Security
purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. The Holders shall be entitled to withdraw
their election if the Trustee or the Company receives not later than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was
delivered for purchase by the Holder and a statement that such Holder is withdrawing his election to have such Security purchased. Holders whose Securities are purchased only in part shall be issued new 

  

 66 

 
Securities equal in principal amount to the unpurchased portion of the Securities surrendered. If the Securities are Global Securities held by the
Depository, then the applicable operational procedures of the Depository for tendering and withdrawing securities will apply. 
 (d) On the
purchase date, all Securities purchased by the Company under this Section shall be delivered to the Trustee for cancellation, and the Company shall pay the purchase price plus accrued and unpaid interest to the Holders entitled thereto. 

(e) A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of Control, if a definitive agreement is
in place for the Change of Control at the time of making of the Change of Control Offer. 
 (f) Notwithstanding the foregoing provisions of
this Section, the Issuers shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in
Section 4.08 applicable to a Change of Control Offer made by the Issuers and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer. 
 (g) Securities repurchased by the Issuers pursuant to a Change of Control Offer will have the status of Securities issued but not outstanding or will be
retired and canceled at the option of the Issuers. Securities purchased by a third party pursuant to the preceding clause (e) will have the status of Securities issued and outstanding. 
 (h) At the time the Company delivers Securities to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’
Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section 4.08 and confirming whether the Securities will be considered issued but not outstanding, or include orders
to cancel the repurchased Securities. A Security shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. 
 (i) Prior to mailing notice to the Holders of any Change of Control Offer, the Company shall deliver to the Trustee an Officers’ Certificate stating
that all conditions precedent contained herein to the right of the Company to make such offer have been complied with. 
 (j) The Issuers
shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section. To the extent that the
provisions of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under this
Section by virtue thereof. 
 SECTION 4.09. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the
end of each fiscal year of the Company, beginning with the fiscal year end on March 31, 2010, an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would
normally have knowledge of any Default and whether or not the signers know of any Default that occurred 

  

 67 

 
during such period. If they do, the certificate shall describe the Default, its status and what action the Company is taking or proposes to take with respect
thereto. The Company also shall comply with Section 314(a)(4) of the TIA. 
 SECTION 4.10. Further Instruments and Acts. Upon
request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 SECTION 4.11. Future Guarantors. The Company shall cause each Restricted Subsidiary that is a Domestic Subsidiary (unless such Subsidiary is a
Receivables Subsidiary) that 
 (i) guarantees any Indebtedness of the Company or any of its Restricted Subsidiaries, or

 (ii) incurs any Indebtedness or issues any shares of Disqualified Stock permitted to be Incurred or issued pursuant to
clauses (i) or (xii) of Section 4.03(b) or not permitted to be Incurred by Section 4.03, 
 to execute and deliver to the Trustee a
supplemental indenture substantially in the form of Exhibit D pursuant to which such Subsidiary shall guarantee the Issuers’ Obligations under the Securities and the Indenture. 
 SECTION 4.12. Liens. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or
suffer to exist any Lien on any asset or property of the Company or such Restricted Subsidiary securing Indebtedness unless the Securities are equally and ratably secured with (or on a senior basis to, in the case of obligations subordinated in
right of payment to the Securities) the obligations so secured until such time as such obligations are no longer secured by a Lien. The preceding sentence shall not require the Company or any Restricted Subsidiary of the Company to secure the
Securities if the Lien consists of a Permitted Lien. Any Lien which is granted to secure the Securities or such Guarantee under this Section 4.12 shall be automatically released and discharged at the same time as the release of the Lien that
gave rise to the obligation to secure the Securities or such Guarantee under this Section 4.12. 
 SECTION 4.13. [Reserved] 

SECTION 4.14. Maintenance of Office or Agency. (a) The Company shall maintain an office or agency (which may be an office of the Trustee
or an affiliate of the Trustee or Registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The
Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations and surrenders may be made at the corporate trust place of payment located at 608 Second Avenue South, N9303-121, Minneapolis, Minnesota 55479, Attention: Corporate Trust Operations, and notices
and demands may be made or served at the corporate trust office of the Trustee as set forth in Section 13.02. 
  

 68 

 (b) The Company may also from time to time designate one or more other offices or agencies where the
Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 (c) The Company hereby designates the corporate trust office of the Trustee or its Agent as such office or agency of the Company in accordance with
Section 2.04. 
 ARTICLE 5

or indirectly, consolidate, amalgamate or merge with or into or wind up or convert into (whether or not the Company is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties
or assets in one or more related transactions, to any Person unless: 
 (i) the Company is the surviving Person or the Person
formed by or surviving any such consolidation, amalgamation, merger, winding up or conversion (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation,
partnership or limited liability company organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (the Company or such Person, as the case may be, being herein called the
“Successor Company”); provided that in the case where the surviving Person is not a corporation, a co-obligor of the Securities is a corporation; 
 (ii) the Successor Company (if other than the Company) expressly assumes all the obligations of the Company under this Indenture and the
Securities pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee; 
 (iii) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any of its Restricted Subsidiaries as a result of such transaction as having been Incurred by
the Successor Company or such Restricted Subsidiary at the time of such transaction) no Default or shall have occurred and be continuing; 
 (iv) immediately after giving pro forma effect to such transaction, as if such transaction had occurred at the beginning of the applicable four-quarter period (and treating any Indebtedness which becomes an obligation
of the Successor Company or any of its Restricted Subsidiaries as a result of such transaction as having been Incurred by the Successor Company or such Restricted Subsidiary at the time of such transaction), either 
  

 69 

 (A) the Successor Company would be permitted to Incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.03(a); or 
 (B) the Fixed Charge
Coverage Ratio for the Successor Company and its Restricted Subsidiaries would be greater than such ratio for the Company and its Restricted Subsidiaries immediately prior to such transaction; 
 (v) each Guarantor, unless it is the other party to the transactions described above, shall have by supplemental indenture confirmed that
its Guarantee shall apply to such Person’s obligations under this Indenture and the Securities; 
 (vi) if the Successor
Company is not organized as a corporation after such transaction, a successor corporation that is a Subsidiary of the Successor Company shall continue to be co-obligor of the Securities and shall have by supplemental indenture confirmed its
obligation under this Indenture and the Securities; and 
 (vii) the Company shall have delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indentures (if any) comply with this Indenture. 
 The Successor Company (if other than the Company) shall succeed to, and be substituted for, the Company under this Indenture and the Securities, and in
such event the Company will automatically be released and discharged from its obligations under this Indenture and the Securities. Notwithstanding the foregoing clauses (iii) and (iv) of this Section 5.01, (a) any Restricted
Subsidiary may merge, consolidate or amalgamate with or transfer all or part of its properties and assets to the Company or to another Restricted Subsidiary, and (b) the Company may merge, consolidate or amalgamate with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another state of the United States, the District of Columbia or any territory of the United States so long as the amount of Indebtedness of the Company and its Restricted
Subsidiaries is not increased thereby. This Article 5 will not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among the Company and its Restricted Subsidiaries. 
 (b) Subject to the provisions of Section 11.02(b) (which govern the release of a Guarantee upon the sale or disposition of a Restricted Subsidiary
of the Company that is a Guarantor), neither Rexnord nor any Guarantor shall, and the Company shall not permit Rexnord or any Guarantor to, consolidate, amalgamate or merge with or into or wind up into (whether or not Rexnord or such Guarantor is
the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person (other than any such sale, assignment, transfer, lease,
conveyance or disposition in connection with the Apollo Transactions) unless: 
 (i) either (A) Rexnord or such
Guarantor, as the case may be, is the surviving Person or the Person formed by or surviving any such consolidation, amalgamation or 

  

 70 

 
merger (if other than Rexnord or such Guarantor, as the case may be) or to which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made is a corporation, partnership or limited liability company organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (Rexnord, such Guarantor or such Person,
as the case may be, being herein called the “Successor Co-Issuer” in the case of a consolidation, amalgamation, merger, winding up or sale, assignment, transfer, lease, conveyance or other disposal of all or substantially all of the
properties or assets of Rexnord, and the “Successor Guarantor,” in the case of a consolidation, amalgamation, merger, winding up or sale, assignment, transfer, lease, conveyance or other disposal of all or substantially all of the
properties or assets of a Guarantor) and the Successor Co-Issuer or Successor Guarantor (if other than Rexnord or such Guarantor, as the case may be) expressly assumes all the obligations of Rexnord or such Guarantor, as the case may be, under this
Indenture and, if applicable, such Guarantors’ Guarantee pursuant to a supplemental indenture or other documents or instruments in form reasonably satisfactory to the Trustee, or (b) other than in the case of a sale, disposition,
consolidation, amalgamation or merger of Rexnord, such sale or disposition or consolidation, amalgamation or merger is not in violation of Section 4.06; 
 (ii) the Successor Co-Issuer (if other than Rexnord) expressly assumes all the obligations of Rexnord under this Indenture and the
Securities pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee; and 
 (iii) the Successor Co-Issuer or Successor Guarantor (if other than Rexnord or such Guarantor, as the case may be) shall have delivered or caused to be delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that such consolidation, amalgamation, merger or transfer and such supplemental indenture (if any) comply with this Indenture. 
 Except as otherwise provided in this Indenture, the Successor Co-Issuer or Successor Guarantor (if other than Rexnord or such Guarantor, as the case may be) will succeed to, and be substituted for, Rexnord or such Guarantor, as the case may
be, under this Indenture and, if applicable, such Guarantor’s Guarantee, and Rexnord or such Guarantor, as the case may be, will automatically be released and discharged from its obligations under this Indenture and, if applicable, such
Guarantor’s Guarantee. Notwithstanding the foregoing, (1) Rexnord or a Guarantor may merge, amalgamate or consolidate with an Affiliate incorporated solely for the purpose of reincorporating Rexnord or such Guarantor in another state of
the United States, the District of Columbia or any territory of the United States so long as the amount of Indebtedness of Rexnord or the Guarantor is not increased thereby and (2) Rexnord or a Guarantor may merge, amalgamate or consolidate
with another Guarantor or the Company. 
 In addition, notwithstanding the foregoing, Rexnord or any Guarantor may consolidate, amalgamate or
merge with or into or wind up into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets (collectively, a “Transfer”) to, (x) the Company, Rexnord or any Guarantor or
(y) any Restricted Subsidiary of the Company that is not Rexnord or a Guarantor; provided that at the time of each such Transfer pursuant to 

  

 71 

 
clause (y) the aggregate amount of all such Transfers since the Issue Date shall not exceed 5.0% of the consolidated assets of the Company, Rexnord and
the Guarantors as shown on the most recent available balance sheet of the Company and the Restricted Subsidiaries after giving effect to each such Transfer and including all Transfers occurring from and after the Issue Date (excluding Transfers in
connection with the Apollo Transactions). 
 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 SECTION 6.01. Events of Default. An “Event of Default”
occurs if: 
 (a) there is a default in any payment of interest (including any additional interest) on any Security when the
same becomes due and payable, and such default continues for a period of 30 days, 
 (b) there is a default in the payment of
principal or premium, if any, of any Security when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise, 
 (c) either of the Issuers or any of the Restricted Subsidiaries of the Company fails to comply with its obligations under
Section 5.01, 
 (d) either of the Issuers or any of the Restricted Subsidiaries of the Company fails to comply with any
of its agreements in the Securities or this Indenture (other than those referred to in clause (a), (b) or (c) above) and such failure continues for 60 days after the notice specified below, 
 (e) either of the Issuers or any Significant Subsidiary fails to pay any Indebtedness (other than Indebtedness owing to either of the
Issuers or a Restricted Subsidiary of the Company) within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default, in each case, if the total amount of such
Indebtedness unpaid or accelerated exceeds $20 million or its foreign currency equivalent, 
 (f) either of the Issuers or any
Significant Subsidiary of the Company pursuant to or within the meaning of any Bankruptcy Law: 
 (i) commences a voluntary
case; 
 (ii) consents to the entry of an order for relief against it in an involuntary case; 
 (iii) consents to the appointment of a Custodian of it or for any substantial part of its property; or 
 (iv) makes a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating to
insolvency, 
  

 72 

 (g) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law
that: 
 (i) is for relief against either of the Issuers or any Significant Subsidiary of the Company in an involuntary case;

 (ii) appoints a Custodian of either of the Issuers or any Significant Subsidiary of the Company or for any substantial part
of its property; or 
 (iii) orders the winding up or liquidation of either of the Issuers or any Significant Subsidiary of
the Company; 
 or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days,

 (h) either of the Issuers or any Significant Subsidiary fails to pay final judgments aggregating in excess of $20 million
or its foreign currency equivalent (net of any amounts which are covered by enforceable insurance policies issued by solvent carriers), which judgments are not discharged, waived or stayed for a period of 60 days following the entry thereof, or

 (i) any Guarantee of a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms
thereof) or any Guarantor denies or disaffirms its obligations under this Indenture or any Guarantee and such Default continues for 10 days after the notice specified below. 
 The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 
 The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator,
custodian or similar official under any Bankruptcy Law. 
 A Default under clause (d) above shall not constitute an Event of Default
until the Trustee notifies the Issuers or the Holders of at least 25% in principal amount of the outstanding Securities notify the Issuers and the Trustee of the Default and the Issuers do not cure such Default within the time specified in clause
(d) above after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” The Issuers shall deliver to the Trustee, within five (5) Business Days
after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Issuers are
taking or propose to take with respect thereto. 
 SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.01(f) or (g) with respect to either of the Issuers) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding 

  

 73 

 
Securities, by notice to the Issuers may, and if such notice is given by the Holders such notice shall be given to the Issuers and the Trustee declare that
the principal of, premium, if any, and accrued but unpaid interest on all the Securities is due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in
Section 6.01(f) or (g) with respect to either of the Issuers occurs, the principal of, premium, if any, and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on
the part of the Trustee or any Holders. The Holders of a majority in principal amount of the Securities by notice to the Trustee may rescind an acceleration and its consequences. 
 In the event of any Event of Default specified in Section 6.01(e), such Event of Default and all consequences thereof (excluding, however, any
resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders of the Securities, if within 20 days after such Event of Default arose the Issuers deliver an Officers’
Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case
may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Securities as described above
be annulled, waived or rescinded upon the happening of any such events. 
 SECTION 6.03. Other Remedies. If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other
remedy. To the extent required by law, all available remedies are cumulative. 
 SECTION 6.04. Waiver of Past Defaults. Provided the
Securities are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the Securities by written notice to the Trustee may waive an existing Default and its consequences except (a) a
Default in the payment of the principal of or interest on a Security, (b) a Default arising from the failure to redeem or purchase any Security when required pursuant to the terms of this Indenture or (c) a Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured and the Issuers, the Trustee and the Holders will be restored to their former positions and rights
under this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. 
 SECTION 6.05.
Control by Majority. The Holders of a majority in principal amount of the Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on
the Trustee. 

  

 74 

 
However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its
sole discretion against all losses and expenses caused by taking or not taking such action. 
 SECTION 6.06. Limitation on Suits.
(a) Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless: 
 (i) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; 
 (ii) the Holders of at least 25% in principal amount of the Securities make a written request to the Trustee to pursue the remedy;

 (iii) such Holder or Holders offer to the Trustee reasonable security or indemnity satisfactory to it against any loss,
liability or expense; 
 (iv) the Trustee does not comply with the request within 60 days after receipt of the request and the
offer of security or indemnity; and 
 (v) the Holders of a majority in principal amount of the Securities do not give the
Trustee a direction inconsistent with the request during such 60-day period. 
 (b) A Holder may not use this Indenture to prejudice the
rights of another Holder or to obtain a preference or priority over another Holder. 
 SECTION 6.07. Rights of the Holders to Receive
Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed or provided for in the
Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust against the Issuers or any other obligor on the Securities for the whole amount then due and owing (together with interest on overdue principal and (to the extent
lawful) on any unpaid interest at the rate provided for in the Securities) and the amounts provided for in Section 7.07. 
 SECTION
6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation,
expenses disbursements and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the
Issuers or any Guarantor, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official 

  

 75 

 
committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election
of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under
Section 7.07. 
 SECTION 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay
out the money or property in the following order: 
 FIRST: to the Trustee for amounts due under Section 7.07;

 SECOND: to the Holders for amounts due and unpaid on the Securities for principal, premium, if any, and interest, ratably,
without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and 
 THIRD: to the Company or, to the extent the Trustee collects any amount for any Guarantor, to such Guarantor. 
 The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section. At least 15 days before such record date, the Trustee shall mail to each Holder and the Issuers a notice that states the record
date, the payment date and amount to be paid. 
 SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and
the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the Securities. 
 SECTION 6.12. Waiver of Stay or Extension Laws. Neither the Issuers nor any Guarantor (to the extent it may lawfully do so) shall at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and
the Issuers and each Guarantor (to the extent that it may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had been enacted. 
  

 76 

 ARTICLE 7 
 TRUSTEE 
 SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such
person’s own affairs. 
 (b) Except during the continuance of an Event of Default: 
 (i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied
covenants or obligations shall be read into this Indenture against the Trustee (it being agreed that the permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty); and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee shall be under no duty to make any investigation as to any statement contained in any such
instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. However, in the case of certificates or opinions required by any provision hereof to be provided to it, the
Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 
 (c)
The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (i) this paragraph does not limit the effect of paragraph (b) of this Section; 
 (ii)
the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; 
 (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction
received by it pursuant to Section 6.05; and 
 (iv) no provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers. 
 (d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. 
  

 77 

 (e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may
agree in writing with the Issuers. 
 (f) Money held in trust by the Trustee need not be segregated from other funds except to the extent
required by law. 
 (g) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section and to the provisions of the TIA. 
 SECTION 7.02. Rights of Trustee.
(a) The Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel. 
 (c)
The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 
 (d)
The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful
misconduct or negligence. 
 (e) The Trustee may consult with counsel of its own selection and the advice or opinion of counsel with respect
to legal matters relating to this Indenture and the Securities or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in
accordance with the advice or opinion of such counsel or Opinion of Counsel. 
 (f) The Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document unless requested in writing to do so by the Holders
of not less than a majority in principal amount of the Securities at the time outstanding, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuers, personally or by agent or attorney, at the expense of the Issuers and shall incur no liability of any kind by
reason of such inquiry or investigation. 
 (g) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it
by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which
might be incurred by it in compliance with such request or direction. 
  

 78 

 (h) The rights, privileges, protections, immunities and benefits given to the Trustee, including its
right to be compensated, reimbursed and indemnified as provided in Section 7.07, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act
hereunder. 
 (i) The Trustee shall not be liable for any action taken or omitted by it in good faith at the direction of the Holders of not
less than a majority in principal amount of the Securities as to the time, method and place of conducting any proceedings for any remedy available to the Trustee or the exercising of any power conferred by the Indenture. 
 (j) Any action taken, or omitted to be taken, by the Trustee in good faith pursuant to this Indenture upon the request or authority or consent of any
person who, at the time of making such request or giving such authority or consent, is the Holder of any Security shall be conclusive and binding upon future Holders of Securities and upon Securities executed and delivered in exchange therefor or in
place thereof. 
 SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner
or pledgee of Securities and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, the Trustee must comply with
Sections 7.10 and 7.11. 
 SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture, any Guarantee or the Securities, it shall not be accountable for the Issuers’ use of the proceeds from the Securities, and it shall not be responsible for any statement of the
Issuers or any Guarantor in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication. The Trustee shall not be charged with knowledge of
any Default or Event of Default under Sections 6.01(c), (d), (e), (h), or (i) or of the identity of any Significant Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have
received written notice thereof in accordance with Section 13.02 hereof from the Issuers, any Guarantor or any Holder. 
 SECTION 7.05.
Notice of Defaults. If a Default occurs and is continuing and if it is actually known to the Trustee, the Trustee shall mail to each Holder notice of the Default within the earlier of 90 days after it occurs or 30 days after it is actually
known to a Trust Officer or written notice of it is received by the Trustee. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Security, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the notice is in the interests of the Holders. 
 SECTION 7.06.
Reports by Trustee to the Holders. As promptly as practicable after each March 31 beginning with the March 31 following the date of this Indenture, and in any event prior to May 31 in each year, the Trustee shall mail to each
Holder a brief report dated as of such March 31 that complies with Section 313(a) of the TIA if and to the extent required thereby. The Trustee shall also comply with Section 313(b) of the TIA. 
  

 79 

 A copy of each report at the time of its mailing to the Holders shall be filed with the SEC and each
stock exchange (if any) on which the Securities are listed. The Issuers agree to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. 
 SECTION 7.07. Compensation and Indemnity. The Issuers shall pay to the Trustee from time to time reasonable compensation for its services. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuers and each
Guarantor, jointly and severally shall indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by or in connection with the acceptance or administration of
this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or Guarantee against the Issuers or a Guarantor (including this Section 7.07) and defending itself against or investigating any
claim (whether asserted by the Issuers, any Guarantor, any Holder or any other Person). The obligation to pay such amounts shall survive the payment in full or defeasance of the Securities or the removal or resignation of the Trustee. The Trustee
shall notify the Issuers of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuers shall not relieve the Issuers or any Guarantor of its
indemnity obligations hereunder. The Issuers shall defend the claim and the indemnified party shall provide reasonable cooperation at the Issuers’ expense in the defense. Such indemnified parties may have separate counsel and the Issuers and
the Guarantors, as applicable shall pay the fees and expenses of such counsel; provided, however, that the Issuers shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such
indemnified parties’ reasonable judgment, there is no conflict of interest between the Issuers and the Guarantors, as applicable, and such parties in connection with such defense. The Issuers need not reimburse any expense or indemnify against
any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, negligence or bad faith. 
 To secure the Issuers’ and the Guarantors’ payment obligations in this Section, the Trustee shall have a Lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in
trust to pay principal of and interest on particular Securities. 
 The Issuers’ and the Guarantors’ payment obligations pursuant
to this Section shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee. Without prejudice to any other rights available to
the Trustee under applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(f) or (g) with respect to the Issuers, the expenses are intended to constitute expenses of administration under
the Bankruptcy Law. 
  

 80 

 No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction.

 SECTION 7.08. Replacement of Trustee. (a) The Trustee may resign at any time by so notifying the Issuers. The Holders of a
majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Issuers shall remove the Trustee if: 
 (i) the Trustee fails to comply with Section 7.10; 
 (ii) the Trustee is adjudged bankrupt or insolvent; 
 (iii) a receiver or other public officer takes charge of the Trustee or its property; or 
 (iv) the Trustee otherwise becomes incapable of acting. 
 (b) If the Trustee resigns, is removed by the Issuers or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy
exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuers shall promptly appoint a successor Trustee. 
 (c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The
retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.07. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities may petition at the
expense of the Issuers any court of competent jurisdiction for the appointment of a successor Trustee. 
 (e) If the Trustee fails to comply
with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in Section 310(b) of the TIA, any Holder who has been a bona fide holder of a Security for at least six months may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (f) Notwithstanding the replacement of the Trustee
pursuant to this Section, the Issuers’ obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 
 SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the
resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 
  

 81 

 In case at the time such successor or successors by merger, conversion or consolidation to the Trustee
shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such
Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 
 SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section 310(a) of the TIA. The
Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Section 310(b) of the TIA, subject to its right to apply for a stay
of its duty to resign under the penultimate paragraph of Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any series of securities issued under this
Indenture and any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuers are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the
TIA are met. 
 SECTION 7.11. Preferential Collection of Claims Against the Issuers. The Trustee shall comply with Section 311(a)
of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated. 
 ARTICLE 8 
 DISCHARGE OF INDENTURE;
DEFEASANCE 
 SECTION 8.01. Discharge of Liability on Securities; Defeasance. This Indenture shall be discharged and shall cease
to be of further effect (except as to surviving rights of registration of transfer or exchange of Securities, as expressly provided for in this Indenture) as to all outstanding Securities when: 
 (a) either (i) all the Securities theretofore authenticated and delivered (other than Securities pursuant to Section 2.08 which
have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust) have been delivered to the
Trustee for cancellation or (ii) all of the Securities (a) have become due and payable, (b) will become due and payable at their stated maturity within one year or (c) if redeemable at the option of the Issuers, are to be called
for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and the Issuers 

  

 82 

 
have irrevocably deposited or caused to be deposited with the Trustee cash in U.S. Dollars, U.S. Government Obligations or a combination thereof in an amount
sufficient in the written opinion of a firm of independent public accountants delivered to the Trustee (which delivery shall only be required if Government Obligations have been so deposited) to pay and discharge the entire Indebtedness on the
Securities not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Securities to the date of deposit together with irrevocable instructions from the Issuers directing the Trustee to apply
such funds to the payment thereof at maturity or redemption, as the case may be; 
 (b) the Issuers and/or the Guarantors have
paid all other sums payable under this Indenture; and 
 (c) the Issuers have delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with. 
 Subject to Sections 8.01(c) and 8.02, the Issuers at any time may terminate (i) all of their obligations under the Securities and this Indenture
(with respect to such Securities) (“legal defeasance option”) or (ii) their obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.11 and 4.12 and the operation of Section 5.01 and Sections 6.01(c), 6.01(d),
6.01(e), 6.01(f) (with respect to Significant Subsidiaries of the Company only), 6.01(g) (with respect to Significant Subsidiaries of the Company only), 6.01(h) and 6.01(i) (“covenant defeasance option”). The Issuers may exercise their
legal defeasance option notwithstanding their prior exercise of their covenant defeasance option. In the event that the Issuers terminate all of their obligations under the Securities and this Indenture (with respect to such Securities) by
exercising their legal defeasance option or their covenant defeasance option, the obligations of each Guarantor under its Guarantee of such Securities shall be terminated simultaneously with the termination of such obligations. 
 If the Issuers exercise their legal defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default. If
the Issuers exercise their covenant defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c), 6.01(d), 6.01(e), 6.01(f) (with respect to Significant Subsidiaries
of the Company only), 6.01(g) (with respect to Significant Subsidiaries of the Company only), 6.01(h) or 6.01(i) or because of the failure of the Issuers to comply with Section 5.01. 
 Upon satisfaction of the conditions set forth herein and upon request of the Issuers, the Trustee shall acknowledge in writing the discharge of those
obligations that the Issuers terminate. 
 (d) Notwithstanding clauses (a) and (b) above, the Issuers’
obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Issuers’ obligations in Sections 7.07, 8.05 and 8.06 shall survive such
satisfaction and discharge. 
  

 83 

 SECTION 8.02. Conditions to Defeasance. (a) The Issuers may exercise their legal defeasance
option or its covenant defeasance option only if: 
 (i) the Issuers irrevocably deposit in trust with the Trustee cash in
U.S. Dollars, U.S. Government Obligations or a combination thereof in an amount sufficient or Government Obligations, the principal of and the interest on which will be sufficient, or a combination thereof sufficient, to pay the principal of and
premium (if any) and interest on the Securities when due at maturity or redemption, as the case may be, including interest thereon to maturity or such redemption date; 
 (ii) the Issuers deliver to the Trustee a certificate from a firm of independent accountants expressing their opinion that the payments of
principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if
any, and interest when due on all the Securities to maturity or redemption, as the case may be; 
 (iii) 123 days pass after
the deposit is made and during the 123-day period no Default specified in Section 6.01(f) or (g) with respect to the Issuers occurs which is continuing at the end of the period; 
 (iv) the deposit does not constitute a default under any other agreement binding on the Issuers; 
 (v) in the case of the legal defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel stating that
(1) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on
the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; 
 (vi) impair the right of any holder to receive payment of principal of, premium, if any, and interest on such holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any
payment on or with respect to such holder’s Securities; 
 (vii) in the case of the covenant defeasance option, the
Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income
tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and 
 (viii) the Issuers deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities to be so defeased and
discharged as contemplated by this Article 8 have been complied with. 
  

 84 

 (b) Before or after a deposit, the Issuers may make arrangements satisfactory to the Trustee for the
redemption of such Securities at a future date in accordance with Article 3. 
 SECTION 8.03. Application of Trust Money. The Trustee
shall hold in trust money or Government Obligations (including proceeds thereof) deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from Government Obligations through each Paying Agent and in accordance
with this Indenture to the payment of principal of and interest on the Securities so discharged or defeased. 
 SECTION 8.04. Repayment to
Company. Each of the Trustee and each Paying Agent shall promptly turn over to the Issuers upon request any money or Government Obligations held by it as provided in this Article which, in the written opinion of nationally recognized firm of
independent public accountants delivered to the Trustee (which delivery shall only be required if Government Obligations have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an
equivalent discharge or defeasance in accordance with this Article. 
 Subject to any applicable abandoned property law, the Trustee and each
Paying Agent shall pay to the Issuers upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Issuers for payment as
general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies. 
 SECTION 8.05.
Indemnity for Government Obligations. The Issuers shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited Government Obligations or the principal and interest received on such
Government Obligations. 
 SECTION 8.06. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or Government
Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’
obligations under this Indenture and the Securities so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or any Paying Agent is permitted to apply all
such money or Government Obligations in accordance with this Article 8; provided, however, that, if the Issuers have made any payment of principal of or interest on, any such Securities because of the reinstatement of their
obligations, the Issuers shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or Government Obligations held by the Trustee or any Paying Agent. 
  

 85 

 ARTICLE 9 
 AMENDMENTS AND WAIVERS 
 SECTION 9.01. Without Consent of the Holders. (a) The Issuers,
the Guarantors and the Trustee may amend this Indenture or the Securities without notice to or consent of any Holder: 
 (i)
to cure any ambiguity, omission, defect or inconsistency; 
 (ii) to provide for the assumption by a Successor Company of the
obligations of the Issuers under this Indenture and the Securities; 
 (iii) to provide for the assumption by a Successor
Guarantor of the obligations of a Guarantor under this Indenture and its Guarantee; 
 (iv) to comply with Article 5;

 (v) to provide for uncertificated Securities in addition to or in place of certificated Securities; provided,
however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code;

 (vi) to add additional Guarantees with respect to the Securities or to secure the Securities; 
 (vii) to add to the covenants of the Issuers for the benefit of the Holders or to surrender any right or power herein conferred upon the
Issuers; 
 (viii) to comply with any requirement of the SEC in connection with qualifying or maintaining the qualification
of, this Indenture under the TIA; 
 (ix) to make any change that does not adversely affect the rights of any Holder; or

 (x) to provide for the issuance of the Exchange Securities or Additional Securities, which shall have terms substantially
identical in all material respects to the Initial Securities, and which shall be treated, together with any outstanding Initial Securities, as a single issue of securities. 
 After an amendment under this Section 9.01 becomes effective, the Issuers shall mail to the Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01. 
 SECTION 9.02. With Consent of the Holders. (a) The Issuers, the Guarantors and the Trustee may amend this Indenture or the Securities with the written consent of the Holders of at least a majority in
principal amount of the Securities then outstanding voting as a 

  

 86 

 
single class (including consents obtained in connection with a tender offer or exchange for the Securities). However, without the consent of each Holder of
an outstanding Security affected, an amendment may not: 
 (i) reduce the amount of Securities whose Holders must consent to
an amendment, 
 (ii) reduce the rate of or extend the time for payment of interest on any Security, 
 (iii) reduce the principal of or change the Stated Maturity of any Security, 
 (iv) reduce the premium payable upon the redemption of any Security or change the time at which any Security may be redeemed in accordance
with Article 3, 
 (v) make any Security payable in money other than that stated in such Security, 
 (vi) expressly subordinate the Securities or any Guarantees to any other Indebtedness of the Issuers or any Guarantor, 
 (vii) impair the right of any Holder to receive payment of principal of or premium, if any, and interest on such Holder’s Securities
on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities, 
 (viii) make any change in Section 6.04 or 6.07 or the second sentence of this Section 9.02, or 
 (ix) modify any Guarantees in any manner adverse to the Holders. 
 It shall not be necessary for the consent
of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment under this Section 9.02 becomes effective, the Issuers shall mail to the Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02. 
 SECTION 9.03. Compliance with Trust Indenture Act. From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement to this Indenture or the Securities shall comply with
the TIA as then in effect. 
 SECTION 9.04. Revocation and Effect of Consents and Waivers. (a) A consent to an amendment or a
waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not
made on the 

  

 87 

 
Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the
Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the Issuers certifying that the requisite principal amount of Securities have consented. After an amendment or waiver becomes
effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt by the Issuers or the Trustee of consents by the Holders of the requisite principal amount of securities, (ii) satisfaction of conditions
to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or supplemental indenture) by the Issuers and the Trustee. 
 (b) The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take
any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent
shall be valid or effective for more than 120 days after such record date. 
 SECTION 9.05. Notation on or Exchange of Securities. If
an amendment, supplement or waiver changes the terms of a Security, the Issuers may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return
it to the Holder. Alternatively, if the Issuers or the Trustee so determines, the Issuers in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such amendment, supplement or waiver. 
 SECTION 9.06. Trustee to
Sign Amendments. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee
may but need not sign it. In signing such amendment, the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and shall be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, an
Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the
Issuers and the Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03).

 GUARANTEES 
 SECTION 11.01. Guarantees. (a) Each Guarantor hereby jointly and severally, irrevocably and
unconditionally guarantees on an unsecured senior basis, as a primary obligor and not merely as a surety, to each Holder and to the Trustee and its successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity,
by acceleration, by redemption or otherwise, of all obligations of the Issuers under this Indenture (including obligations to the Trustee) and the Securities, whether for payment of principal of, premium, if any, or interest on in respect of the
Securities and all other monetary obligations of the Issuers under this Indenture and the Securities and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuers whether for fees, expenses,
indemnification or otherwise under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or
renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 11 notwithstanding any extension or renewal of any Guaranteed Obligation. 
 (b) Each Guarantor waives presentation to, demand of payment from and protest to the Issuers of any of the Guaranteed Obligations and also waives notice
of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any right or remedy against the Issuers or any other Person under this Indenture, the Securities or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities or
any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (iv) the release of any security held by any Holder or the Trustee for
the Guaranteed Obligations or any Guarantor; (v) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of such Guarantor, except
as provided in Section 11.02(b). 
 (c) Each Guarantor hereby waives any right to which it may be entitled to have its obligations
hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives any right to which it 

  

 89 

 
may be entitled to have the assets of the Issuers first be used and depleted as payment of the Issuers’ or such Guarantor’s obligations hereunder
prior to any amounts being claimed from or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Issuers be sued prior to an action being initiated against such Guarantor.

 (d) Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and
not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations. 
 (e) Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06, the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by
reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected
by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful
or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a
discharge of any Guarantor as a matter of law or equity. 
 (f) Each Guarantor agrees that its Guarantee shall remain in full force and
effect until payment in full of all the Guaranteed Obligations. Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of
or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuers or otherwise. 
 (g) In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of the Issuers to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or
comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of
(i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the
Issuers to the Holders and the Trustee. 
 (h) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to
the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand,
(i) the maturity of the 

  

 90 

 
Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of any Guarantee herein, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such
Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 11.01. 
 (i) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this
Section 11.01. 
 (j) Upon request of the Trustee, each Guarantor shall execute and deliver such further instruments and do such further
acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 SECTION 11.02. Limitation on
Liability. (a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby
guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 
 (b) A Guarantee as to any Guarantor shall terminate and be of no further force or effect and such Guarantor shall be deemed to be released from all
obligations under this Article 11 upon: 
 (i) the sale, disposition or other transfer (including through merger or
consolidation) of the Capital Stock (including any sale, disposition or other transfer following which the applicable Guarantor is no longer a Restricted Subsidiary) of the applicable Guarantor if such sale, disposition or other transfer is made in
compliance with this Indenture, 
 (ii) the Company designating such Guarantor to be an Unrestricted Subsidiary in accordance
with the provisions set forth under Section 4.04 and the definition of “Unrestricted Subsidiary,” 
 (iii) in
the case of any Restricted Subsidiary that after the Closing Date is required to guarantee the Securities pursuant to Section 4.11, the release or discharge of the guarantee by such Restricted Subsidiary of Indebtedness of the Company or any
Restricted Subsidiary of the Company or such Restricted Subsidiary or the repayment of the Indebtedness or Disqualified Stock, in each case, which resulted in the obligation to guarantee the Securities, and 
 (iv) the Issuers’ exercise of their defeasance options under Article 8, or if the Issuers’ obligations under this Indenture are
discharged in accordance with the terms of this Indenture. 
  

 91 

 In the case of clause (b)(i) above, such Guarantor shall be released from its guarantees, if any, of, and
all pledges and security, if any, granted in connection with, the Credit Agreement and any other Indebtedness of the Issuers or any Restricted Subsidiary of the Issuers. 
 A Guarantee also shall be automatically released upon the applicable Subsidiary ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest securing Bank Indebtedness or other exercise
of remedies in respect thereof or if such Subsidiary is released from its guarantees of, and all pledges and security interests granted in connection with, the Credit Agreement and any other Indebtedness of the Issuers or any Restricted Subsidiary
of the Company which results in the obligation to guarantee the Securities. 
 SECTION 11.03. Successors and Assigns. This Article 11
shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 
 SECTION 11.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or
privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise. 
 SECTION 11.05. Modification. No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any
Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or
demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances. 
 SECTION 11.06. Execution of Supplemental Indenture for Future Guarantors. Each Subsidiary and other Person which is required to become a Guarantor pursuant to Section 4.11 shall promptly execute and
deliver to the Trustee a supplemental indenture in the form of Exhibit D hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article 11 and shall guarantee the Guaranteed Obligations. Concurrently with the
execution and delivery of such supplemental indenture, the Issuers shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered
by such Subsidiary or other Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity,
whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee
may reasonably request.

 Members of, or direct or indirect participants in, the
Depository (collectively, the “Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Securities. The
Depository may be treated by the Issuers, the Trustee and any agent of the Issuers or the Trustee as the absolute owner of the Global Securities for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers,
the Trustee or any agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository, or impair, as between the Depository and its Agent Members, the operation of customary
practices governing the exercise of the rights of a Holder of any Security. 
 (i)(B) Mandatory Exchange from Transfer Restricted Global
Security into Unrestricted Global Security. Unless the Issuers otherwise request, beneficial interests in the

Restricted Global Security will be automatically exchanged into beneficial interests in the Unrestricted Global Security on the 366th day following the Closing Date if (i) such exchange or transfer complies with the requirements of Section 2.2 below, (ii) the provisions of
Section 2.2(g) would not prohibit the Registrar from delivering Notes that do not bear a Restricted Securities Legend and (iii) no Additional Securities have been issued. Upon satisfaction of the conditions set forth in the immediately

Global Security to the Unrestricted Global Security, which the Company shall have previously otherwise made eligible for transfer within DTC, and (ii) provide prior written notice to all Holders of such transfer, which notice must include the
date of such transfer to occur, the CUSIP number of the relevant Transfer Restricted Global Security and the CUSIP number of the Unrestricted Global Security into which such Holders’ beneficial interests will be transferred. As a condition to
any such transfer pursuant to this Section 2.1(b)(i)(B), the Company shall provide, and the Trustee shall be entitled to rely upon, an Officers’ Certificate and an Opinion of Counsel, in the form and substance reasonably satisfactory to

interests pursuant to this Section 2.1(b)(i)(B), the Registrar shall endorse the Schedule Of Increases or Decreases In Global Security attached to the relevant Global Securities to reflect the relevant increase or decrease in the principal
amount of such Global Security resulting from the applicable transfer. Following any such transfer pursuant to this Section 2.1(b)(1)(B), the Transfer Restricted Global Securities shall be cancelled.

Registrar. 
 (ii) Transfers of Global Securities shall be limited to transfer in whole, but not in part, to the Depository, its successors
or their respective nominees. Interests of beneficial owners in the Global Securities may be transferred or exchanged for Definitive Securities only in accordance with the applicable rules and procedures of the Depository and the provisions of
Section 2.2. In addition, a Global Security shall be exchangeable for Definitive Securities if (x) the Depository (1) notifies the Company that it is unwilling or unable to continue as depository for such Global Security and the
Company thereupon fails to appoint a successor depository or (2) has ceased to be a clearing agency registered under the Exchange Act or (y) there shall have occurred and be continuing an Event of Default with respect to such Global
Security; provided that in no event shall the Regulation S Global Security be exchanged by the Issuers for Definitive Securities prior to (x) the termination of the Restricted Period and delivery of the Officers’ Certificate to the
Trustee pursuant to Section 2.1(b)(i) and (y) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act. In all cases, Definitive Securities delivered in exchange for any Global
Security or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depository in accordance with its customary procedures. 
  

 -4- 

 (iii) In connection with the transfer of a Global Security as an entirety to beneficial owners pursuant

 1. Interest 
 (a) RBS GLOBAL, INC., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein
called “RBS Global”) and REXNORD LLC, a Delaware limited liability company (such company, and its successors and assigns under the Indenture hereinafter referred to, being herein called “Rexnord” and, together with RBS Global,
the “Issuers”), promise to pay interest on the principal amount of this Security at the rate per annum shown above. The Issuers shall pay interest semiannually on May 1 and November 1 of each year, commencing May 1, 2009.
Interest on the Securities shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from April 29, 2009 until the principal hereof is due. Interest shall
be computed on the basis of a 360-day year of twelve 30-day months. The Issuers shall pay interest on overdue principal at the rate borne by the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent
lawful. 
 (b) Registration Rights Agreement. The Holder of this Security is entitled to the benefits of a Registration Rights
Agreement, dated as of April 29, 2009, among the Issuers, the Guarantors and the Dealer Manager. 
 2. Method of Payment 
 The Issuers shall pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders at the close of business on the
April 15 or October 15 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date (whether or not a Business Day), provided, however, that the interest
payment which is due on May 1, 2009 shall be made to all persons who are registered Holders at the close of business on the Closing Date. Holders must surrender Securities to the Paying Agent to collect principal payments. The Issuers
shall pay principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security

of a certificated Security (including principal, premium, if any, and interest) at the office of the Paying Agent, except that, at the option of the Issuers, payment of interest may be made by mailing a check to the registered address of each Holder
thereof; provided, however, that payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).

 4. Indenture

 The Issuers issued the Securities under an Indenture dated as of April 29, 2009 (the “Indenture”), among the Issuers, the
Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the
Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and the Holders (as defined in the
Indenture) are referred to the Indenture and the TIA for a statement of such terms and provisions 
 The Securities are senior unsecured
obligations of the Issuers. This Security is one of the Original Securities referred to in the Indenture. The Securities include the Original Securities, any Additional Securities (together with the Original Securities, the “Initial
Securities”) and any Exchange Securities issued in exchange for the Initial Securities pursuant to the Indenture. The Initial Securities and any Exchange Securities are treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of RBS Global and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, incur Indebtedness, enter into consensual
restrictions upon the payment of certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of capital stock of RBS Global and such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates,
create or incur Liens and make Asset Sales. The Indenture also imposes limitations on the ability of the Issuers and each Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of their
property. 
 To guarantee the due and punctual payment of the principal and interest on the Securities and all other amounts payable by the
Issuers under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Guarantors have, jointly and severally,
unconditionally guaranteed the Guaranteed Obligations on a senior unsecured basis pursuant to the terms of the Indenture. 
 5. Optional Redemption

(other than Disqualified Stock) of the Issuers from it, at a redemption price equal to 109.500% of the principal amount thereof plus accrued and unpaid interest and additional interest, if any, to the redemption date (subject to the right of the
Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that at least 65% of the original aggregate principal amount of the Securities (calculated after giving
effect to any issuance of Additional Securities) must remain outstanding after each such redemption; and provided further that such redemption shall occur within 90 days after the date on which any such Equity Offering is consummated upon not
less than 30 nor more than 60 days’ notice mailed to each Holder of Securities being redeemed and otherwise in accordance with the procedures set forth in the Indenture. Notice of any redemption upon any Equity Offering may be given prior to

 8. Repurchase of Securities at the Option of the Holders upon Change of Control and Asset Sales 
 Upon the occurrence of a Change of Control, each Holder shall have the right, subject to certain conditions specified in the Indenture, to cause the
Issuers to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the
Holders of record on the relevant record date to receive interest due on the relevant interest payment date), as provided in, and subject to the terms of, the Indenture. 
 In accordance with Section 4.06 of the Indenture, the Issuers will be required to offer to purchase Securities upon the occurrence of certain events.

 The Securities are in registered form, without coupons, in denominations of $2,000 and any integral multiple of $1,000. A Holder shall register the
transfer of or exchange of Securities in accordance with the Indenture. Upon any registration of transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents
and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to a selection of Securities to be redeemed. 
 11.
Persons Deemed Owners 
 The registered Holder of this Security shall be treated as the owner of it for all purposes. 
 12. Unclaimed Money

principal or interest remains unclaimed for two years, the Trustee and a Paying Agent shall pay the money back to the Issuers at their written request unless an abandoned property law designates another Person. After any such payment, the Holders
entitled to the money must look to the Issuers for payment as general creditors and the Trustee and a Paying Agent shall have no further liability with respect to such monies. 
  

 A-8 

 13. Discharge and Defeasance 
 Subject to certain conditions, the Issuers at any time may terminate some of or all their obligations under the Securities and the Indenture if the Issuers deposit with the Trustee money or U.S. Government Obligations
for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 
 14. Amendment; Waiver 
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders
of at least a majority in aggregate principal amount of the outstanding Securities (voting as a single class) and (ii) any past default or compliance with any provisions may be waived with the written consent of the Holders of at least a
majority in principal amount of the outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Issuers and the Trustee may amend the Indenture or the Securities (i) to cure any
ambiguity, omission, defect or inconsistency; (ii) to provide for the assumption by a Successor Company of the obligations of the Issuers under the Indenture and the Securities; (iii) to provide for the assumption by a Successor Guarantor
of the obligations of a Guarantor under the Indenture and its Guarantee; (iv) to provide for uncertificated Securities in addition to or in place of certificated Securities (provided that the uncertificated Securities are issued in
registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code); (v) to add Guarantees with respect to the Securities; (vi) to
add additional covenants of the Issuers for the benefit of the Holders or to surrender rights and powers conferred on the Issuers; (vii) to comply with the requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the TIA; (viii) to make any change that does not adversely affect the rights of any Holder; or (ix) to provide for the issuance of the Exchange Securities or Additional Securities. 
 15. Defaults and Remedies 
 If an Event of Default
occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuers) and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities, in each
case, by notice to the Issuers, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Securities to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization
of the Issuers occurs, the principal of, premium, if any, and interest on all the Securities shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the
Holders of a majority in principal amount of the outstanding Securities may rescind any such acceleration with respect to the Securities and its consequences. 
 If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such
Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense and certain other conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest
when 

  

 A-9 

 
due, no Holder may pursue any remedy with respect to the Indenture or the Securities unless (i) such Holder has previously given the Trustee notice that
an Event of Default is continuing, (ii) the Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee in writing to pursue the remedy, (iii) such Holders have offered the Trustee reasonable
security or indemnity against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity and (v) the Holders of a majority in
principal amount of the outstanding Securities have not given the Trustee a direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding
Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the
Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 16. Trustee Dealings with the Issuers 
 Subject to certain limitations imposed by the TIA, the Trustee under the Indenture,
in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Issuers or their Affiliates and may otherwise deal with the Issuers or their Affiliates with
the same rights it would have if it were not Trustee. 
 17. No Recourse Against Others 
 No director, officer, employee, incorporator or holder of any equity interests in the Issuers or of any Guarantor or any direct or indirect parent
corporation, as such, shall have any liability for any obligations of the Issuers or the Guarantors under the Securities, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of
Securities by accepting a Security waives and releases all such liability. 
 18. Authentication 
 This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security. 
 19. Abbreviations 
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 
  

 A-10 

 20. Governing Law 
 THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. 
 21. CUSIP Numbers; ISINs 
 The Issuers have caused
CUSIP numbers and ISINs to be printed on the Securities and have directed the Trustee to use CUSIP numbers and ISINs in notices of redemption as a convenience to the Holders. No representation is made as to the accuracy of such numbers either as

interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depositary. The Issuers shall make all payments in respect of a certificated Security (including
principal, premium, if any, and interest), at the office of the Paying Agent, except that, at the option of the Issuers, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice to the Trustee or Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date
as the Trustee may accept in its discretion). 
 3. Paying Agent and Registrar 
 Initially, Wells Fargo Bank, National Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The
Issuers may appoint and change any Paying Agent or Registrar without notice. The Issuers or any of their domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 
  

 B-4 

 4. Indenture 
 The Issuers issued the Securities under an Indenture dated as of April 29, 2009 (the “Indenture”), among the Issuers, the Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and the Holders (as defined in the Indenture) are referred to the Indenture and the TIA for a statement of such terms and provisions.

 The Securities are senior unsecured obligations of the Issuers. This Security is one of the Original Securities referred to in the
Indenture. The Securities include the Original Securities, any Additional Securities (together with the Original Securities, the “Initial Securities”) and any Exchange Securities issued in exchange for the Initial Securities pursuant to
the Indenture. The Initial Securities and any Exchange Securities are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of RBS Global and its Restricted Subsidiaries to, among other
things, make certain Investments and other Restricted Payments, pay dividends and other distributions, incur Indebtedness, enter into consensual restrictions upon the payment of certain dividends and distributions by such Restricted Subsidiaries,
issue or sell shares of capital stock of RBS Global and such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or incur Liens and make Asset Sales. The Indenture also imposes limitations on the ability of the
Issuers and each Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of their property. 
 To guarantee the due and punctual payment of the principal and interest on the Securities and all other amounts payable by the Issuers under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Guarantors have, jointly and severally, unconditionally guaranteed the Guaranteed Obligations on a senior unsecured basis
pursuant to the terms of the Indenture. 
 5. Optional Redemption 
 Except as set forth in the following two paragraphs, the Securities shall not be redeemable at the option of the Issuers prior to August 1, 2010. Thereafter, the Securities shall be redeemable at the option of
the Issuers, in whole at any time or in part from time to time, upon on not less than 30 nor more than 60 days’ prior notice, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest
and additional interest, if any, to the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on
August 1 of the years set forth below: 
  

				
	 Year

 B-5 

 In addition, prior to August 1, 2010, the Issuers may redeem the Securities at their option, in
whole at any time or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s registered address, at a redemption price equal to 100% of the principal amount of the
Securities redeemed plus the Applicable Premium as of, and accrued and unpaid interest and additional interest, if any, to, the applicable redemption date (subject to the right of the Holders of record on the relevant record date to receive interest
due on the relevant interest payment date). 
 Notwithstanding the foregoing, at any time and from time to time on or prior to August 1,
2009, the Issuers may redeem in the aggregate up to 35% of the original aggregate principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities), with the net cash proceeds of one or more Equity
Offerings (1) by the Issuers or (2) by any direct or indirect parent of the Issuers, in each case, to the extent the net cash proceeds thereof are contributed to the common equity capital of the Issuers or used to purchase Capital Stock
(other than Disqualified Stock) of the Issuers from it, at a redemption price equal to 109.500% of the principal amount thereof plus accrued and unpaid interest and additional interest, if any, to the redemption date (subject to the right of the
Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that at least 65% of the original aggregate principal amount of the Securities (calculated after giving
effect to any issuance of Additional Securities) must remain outstanding after each such redemption; and provided further that such redemption shall occur within 90 days after the date on which any such Equity Offering is consummated upon not
less than 30 nor more than 60 days’ notice mailed to each Holder of Securities being redeemed and otherwise in accordance with the procedures set forth in the Indenture. Notice of any redemption upon any Equity Offering may be given prior to
the completion thereof, and any such redemption or notice may, at the Issuers’ discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering. 
 6. Sinking Fund 
 The Securities are not subject to
any sinking fund. 
 7. Notice of Redemption 
 Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his, her or its registered address. Securities in denominations
larger than $2,000 may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the redemption date is
deposited with a Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption. 
  

 B-6 

 8. Repurchase of Securities at the Option of the Holders upon Change of Control and Asset Sales 
 Upon the occurrence of a Change of Control, each Holder shall have the right, subject to certain conditions specified in the Indenture, to cause the
Issuers to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the
Holders of record on the relevant record date to receive interest due on the relevant interest payment date), as provided in, and subject to the terms of, the Indenture. 
 In accordance with Section 4.06 of the Indenture, the Issuers will be required to offer to purchase Securities upon the occurrence of certain events. 
 9. [Reserved] 
 10. Denominations; Transfer; Exchange 
 The Securities are in registered form, without coupons, in denominations of $2,000 and any integral multiple of $1,000. A Holder shall register the
transfer of or exchange of Securities in accordance with the Indenture. Upon any registration of transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents
and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to a selection of Securities to be redeemed. 
 11.
Persons Deemed Owners 
 The registered Holder of this Security shall be treated as the owner of it for all purposes. 
 12. Unclaimed Money 
 If money for the payment of
principal or interest remains unclaimed for two years, the Trustee and a Paying Agent shall pay the money back to the Issuers at their written request unless an abandoned property law designates another Person. After any such payment, the Holders
entitled to the money must look to the Issuers for payment as general creditors and the Trustee and a Paying Agent shall have no further liability with respect to such monies. 
 13. Discharge and Defeasance 
 Subject to certain conditions, the Issuers at any time may terminate
some of or all its obligations under the Securities and the Indenture if the Issuers deposit with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may
be. 
  

 B-7 

 14. Amendment; Waiver 
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the
outstanding Securities (voting as a single class) and (ii) any past default or compliance with any provisions may be waived with the written consent of the Holders of at least a majority in principal amount of the outstanding Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Issuers and the Trustee may amend the Indenture or the Securities (i) to cure any ambiguity, omission, defect or inconsistency; (ii) to
provide for the assumption by a Successor Company of the obligations of the Issuers under the Indenture and the Securities; (iii) to provide for the assumption by a Successor Guarantor of the obligations of a Guarantor under the Indenture and
its Guarantee; (iv) to provide for uncertificated Securities in addition to or in place of certificated Securities (provided that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the
Code, or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code); (v) to add Guarantees with respect to the Securities; (vi) to add additional covenants of the Issuers for the benefit of
the Holders or to surrender rights and powers conferred on the Issuers; (vii) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA; (viii) to make any change that does
not adversely affect the rights of any Holder; or (ix) to provide for the issuance of the Exchange Securities or Additional Securities. 
 15.
Defaults and Remedies 
 If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy,
insolvency or reorganization of the Issuers) and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities, in each case, by notice to the Issuers, may declare the principal of, premium, if any, and
accrued but unpaid interest on all the Securities to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuers occurs, the principal of, premium, if any, and interest on all the
Securities shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Securities may rescind
any such acceleration with respect to the Securities and its consequences. 
 If an Event of Default occurs and is continuing, the Trustee
shall be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability
or expense and certain other conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Securities unless
(i) such Holder has previously given the Trustee notice that an Event of Default is continuing, (ii) the Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee in writing to pursue the remedy,
(iii) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of
security or indemnity and (v) the Holders of a majority in principal amount of the outstanding Securities 

  

 B-8 

 
have not given the Trustee a direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the Holders of a majority
in principal amount of the outstanding Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The
Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to
taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 16. Trustee Dealings with the Issuers 
 Subject to
certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Issuers or their
Affiliates and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee. 
 17. No Recourse
Against Others 
 No director, officer, employee, incorporator or holder of any equity interests in the Issuers or of any Guarantor or any
direct or indirect parent corporation, as such, shall have any liability for any obligations of the Issuers or the Guarantors under the Securities, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Securities by accepting a Security waives and releases all such liability. 
 18. Authentication 
 This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security. 
 19. Abbreviations 
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 
 20. Governing Law 
 THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF
LAW. 
  

 B-9 

 21. CUSIP Numbers; ISINs 
 The Issuers have caused CUSIP numbers and ISINs to be printed on the Securities and have directed the Trustee to use CUSIP numbers and ISINs in notices of redemption as a convenience to the Holders. No representation
is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
