Form of Equity Restriction Agreement

 EXHIBIT 10.4 
 FORM OF 
 EQUITY RESTRICTION AGREEMENT 
 This EQUITY RESTRICTION AGREEMENT (this “Agreement”) is made as of November •, 2006, by and between SunPower Corporation, a
Delaware corporation (“Parent”), and • (“Equity Holder”). Capitalized terms used but not otherwise defined herein shall have the meaning ascribed to them in the Merger Agreement (as defined
below). 
 BACKGROUND 
 A.
Concurrently with the execution of this Agreement, Parent, Pluto Acquisition Company LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Parent (“Merger Sub”), PowerLight Corporation, a
California corporation (the “Company”), and Thomas L. Dinwoodie, as the representative of certain of the Company’s shareholders, entered into an Agreement and Plan of Merger (the “Merger
Agreement”) pursuant to which the Company has agreed, subject to the conditions set forth in the Merger Agreement, to merge with and into Merger Sub with Merger Sub surviving as a wholly owned subsidiary of Parent (the
“Merger”). 
 B. If the Merger is approved by the requisite vote of the shareholders of the Company and the Merger is
consummated, in connection with the Merger, in exchange for the shares of Company Capital Stock held by Equity Holder, Equity Holder will receive pursuant to Section 1.4 of the Merger Agreement a cash amount and shares of Parent Common Stock
(the “Shares”). 
 C. If the Merger is approved by the requisite vote of the shareholders of the Company and the
Merger is consummated, in connection with the Merger, the portion of each option held by Equity Holder to acquire shares of Company Common Stock that is vested as of immediately after the Effective Time of the Merger shall be converted into the
right to receive a cash amount and an option to acquire Shares, the terms of which are set forth in Section 4.14(a)(i) of the Merger Agreement (a “Vested Parent Stock Option”). 
 D. As a condition to the closing of the transactions contemplated by the Merger Agreement, the Merger Agreement contemplates, among other things, that
Equity Holder shall enter into this Agreement concurrently with the execution of the Merger Agreement and that this Agreement will become effective, if the Merger is approved by the requisite vote of the shareholders of the Company and the Merger is
consummated, at the Effective Time. 
 E. Of Equity Holder’s combined total number of Shares described in B above and issuable upon
exercise of Vested Parent Stock Options described in C above (the “Combined Shares”), 50% of such aggregate number (determined in accordance with Section 2(b), the “Restricted Shares”) shall be
subject to the Repurchase Option and other restrictions as set forth in this Agreement and 50% (including all shares deposited into the Stock Escrow Fund pursuant to Section 1.4 of the Merger Agreement) shall not be subject to the Repurchase
Option or other restrictions set forth in this Agreement (the “Unrestricted Shares”). To the extent that the term “Restricted Shares” refers to Shares issuable upon exercise of a Vested Parent Stock Option, the
Repurchase Option shall be exercisable against the Vested Parent Stock Option itself, without the payment of any monetary consideration, to the extent that such option has not been exercised, and the term “Restricted Shares” shall mean the
Vested Parent Stock Option. 
 AGREEMENT 
 The parties to this Agreement, intending to be legally bound, agree as follows: 
 1. Definitions.

 For purposes of this Agreement: 
 (a) “Cause” means (i) acts or omissions constituting gross negligence or willful misconduct on the part of Equity Holder with respect to Equity Holder’s obligations or otherwise
relating to the business of Parent or the Company, (ii) Equity Holder’s (A) felony conviction of, or felony plea of nolo contendere for, fraud, misappropriation or embezzlement, or a felony crime of moral turpitude, or
(B) conviction of fraud, misappropriation or embezzlement, (iii) Equity Holder’s violation or breach of any fiduciary duty, or (iv) Equity Holder’s violation or breach of any contractual duty to Parent or the Company which
duty is material to the performance of the Equity Holder’s duties or results in material damage to Parent, the Company or their business; provided that if any of the foregoing events is capable of being cured, Parent will provide notice
to Equity Holder describing the nature of such event and Equity Holder will thereafter have 30 days to cure such event. 

 (b) “disability” means Equity Holder’s failure to perform
the essential functions of Equity Holder’s position for a period of six months, with or without reasonable accommodation, due to a disability, which, in the opinion of a qualified physician, is reasonably likely to be continuous or permanent
for the remainder of Equity Holder’s life. 
 (c) “Good Reason” means the occurrence of any of
the following without Equity Holder’s express prior written consent: (i) a material reduction in Equity Holder’s position or duties after the Closing Date, (ii) a material breach of the Equity Holder’s employment agreement,
unless such breach becomes cured by the Parent within 30 days after notice of such breach from the Equity Holder, (iii) a reduction in Equity Holder’s then-current base salary and target bonus, excluding a reduction that is applied to
substantially all of Parent’s and the Company’s other senior executives, determined without regard to any actual bonus payments made to Equity Holder, (iv) a material reduction in the aggregate level of benefits made available to
Equity Holder other than a reduction applied to substantially all of Parent’s and the Company’s other senior executives, (v) a relocation of Equity Holder’s primary place of business to a location that is more than 35 miles from
the Company’s current location in Berkeley, California, or (vi) with respect to only Mr. Dinwoodie, a change in his reporting responsibility after the Effective Time of the Merger. 
 (d) “Transfer” means (a) any offer, pledge, sale, contract to sell, sale of any option or contract to
purchase, purchase of any option or contract to sell, grant of any option, right or warrant to purchase, lending or other transfer or disposition of, directly or indirectly, any shares of Parent Common Stock or any securities convertible into or
exercisable or exchangeable for Parent Common Stock, or (b) the entering into of any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Parent Common Stock, whether any
such transaction described in clause (a) or (b) above is to be settled by delivery of Parent Common Stock or such other securities, in cash or otherwise. 
 2. Restricted Shares Subject to Repurchase Option. If the Merger is approved by the requisite vote of the shareholders of the Company and the Merger is consummated, as of the Effective Time: 
 (a) In the event of any (i) voluntary termination by Equity Holder of Equity Holder’s employment with Parent other than for Good
Reason, or (ii) involuntary termination of Equity Holder’s employment with Parent by Parent for Cause, in each case before all of the Restricted Shares are released from the Repurchase Option (see Section 2(b) below), Parent shall,
upon the date of such termination have an irrevocable option (the “Repurchase Option”) for a period of 90 days from such date to repurchase all or any portion of the Restricted Shares which are, at the date of such
termination, Unreleased Shares (as defined in Section 2(b) below) at $0.01 per share (the “Repurchase Price”). For purposes of this Agreement, Equity Holder shall be deemed to be employed by Parent if Equity Holder is
employed by Parent or any of its Subsidiaries. For the sake of clarity, to the extent that the term “Restricted Shares” refers to Shares issuable upon exercise of a Vested Parent Stock Option, the Repurchase Option shall be exercisable
against the Vested Parent Stock Option itself, without the payment of any monetary consideration, to the extent that such option has not been exercised, and the term “Restricted Shares” shall mean the Vested Parent Stock Option.

 (b) Subject to Section 2(h), one-fourth of the Restricted Shares shall be released from the Repurchase Option on the
date that is six months after the Closing Date, one-fourth of the Restricted Shares shall be released from the Repurchase Option on the date that is 12 months after the Closing Date, one-fourth of the Restricted Shares shall be released from the
Repurchase Option on the date that is 18 months after the Closing Date, and one-fourth of the Restricted Shares shall be released from the Repurchase Option on the date that is 24 months after the Closing Date; provided that Equity
Holder’s employment by Parent has not been terminated under the circumstances described in Section 2(a) above prior to the date of any such release. Any of the Restricted Shares that have not yet been released from the Repurchase Option
are referred to herein as “Unreleased Shares.” Notwithstanding anything to the contrary herein, (i) in determining which shares of the Combined Shares constitute Restricted Shares, shares issuable upon exercise of Vested
Parent Stock Options shall be counted first, and Shares issued pursuant to Section 1.4 of the Merger Agreement shall constitute Restricted Shares second and only to the extent that the number of shares issuable upon exercise of Vested Parent
Stock Options received by the Equity Holder as described in Recital C is less than 50% of the aggregate number of Combined Shares, and (ii) for purposes of determining whether any share of the Combined Shares which the Equity Holder Transfers
or attempts to Transfer is a Restricted Share or an 

  

 2 

 
Unrestricted Share, such Share shall be deemed to be an Unrestricted Share unless and until such Equity Holder Transfers or attempts to Transfer a number of
shares equal to the number of Unrestricted Shares then held by such Equity Holder, after which all remaining shares of the Combined Shares shall be deemed to be Restricted Shares. 
 (c) The Repurchase Option shall be exercised by Parent by written notice to Equity Holder (with a copy to the Escrow Agent (as defined
below)) and by delivery to Equity Holder with such notice of a check in the amount (the “Total Purchase Price”) of the product of (i) the Repurchase Price, and (ii) the number of the Unreleased Shares being
repurchased. Upon delivery of such notice and the payment of the Total Purchase Price, Parent shall become the legal and beneficial owner of the Unreleased Shares being repurchased and all rights and interests therein or relating thereto, and Parent
shall have the right to retain and transfer to its own name the Unreleased Shares being repurchased by Parent. Whenever Parent shall have the right to repurchase Unreleased Shares hereunder, Parent may designate and assign one or more employees,
officers, directors or equity holders of Parent or other persons or organizations to exercise all or a part of Parent’s purchase rights under this Agreement and purchase all or a part of such Unreleased Shares. 
 (d) Equity Holder agrees to deliver the certificate(s) evidencing the Restricted Shares, together with a stock assignment in the form
attached hereto as Exhibit A with respect to such Restricted Shares (as such shares are issued to Equity Holder), executed by Equity Holder (with the date and number of shares left blank), to an escrow holder designated by Parent (the
“Escrow Agent”). The certificate(s) and stock assignment are to be held by the Escrow Agent pursuant to the Joint Escrow Instructions of Parent and Equity Holder set forth in Exhibit B attached hereto, which
instructions shall also be delivered to the Escrow Agent. The Escrow Agent shall have no liability for any act or omission hereunder while acting in good faith. 
 (e) Subject to the terms hereof, Equity Holder shall have all the rights of an Equity Holder with respect to the Restricted Shares while
they are held in escrow, including without limitation, the right to vote the Restricted Shares and to receive any cash dividends declared thereon. If, from time to time during the term of the Repurchase Option, there is (i) any stock dividend,
stock split or other change in the Restricted Shares, or (ii) any merger or sale of all or substantially all of the assets or other acquisition of Parent where the Unreleased Shares are not released from the Repurchase Option, then any and all
new, substituted or additional securities to which Equity Holder is entitled by reason of Equity Holder’s ownership of the Restricted Shares shall be immediately subject to this escrow, deposited with the Escrow Agent and included thereafter as
“Restricted Shares” for purposes of this Agreement and the Repurchase Option. 
 (f) Except as otherwise provided in
this Section 2(f), Equity Holder agrees that none of the Restricted Shares (or any beneficial interest therein) shall be Transferred in any way until such Restricted Shares are released from the Repurchase Option in accordance with this
Agreement. Notwithstanding the foregoing, Equity Holder may transfer the Restricted Shares, in whole or in part, to a spouse or lineal descendant (a “Family Member”), a trust for the exclusive benefit of Equity Holder and/or Family
Members, or a partnership or other entity in which all the beneficial owners are Equity Holder and/or Family Members, provided that the transferee agrees to be bound by the terms of this Agreement. 
 (g) The share certificate evidencing the Restricted Shares issued hereunder shall be endorsed with the following legend: 
 THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF A STOCK RESTRICTION AGREEMENT BETWEEN THE COMPANY AND
THE HOLDER OF THE SHARES REPRESENTED BY THIS CERTIFICATE, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE CORPORATION. 
 3.
Notwithstanding anything to the contrary in this Agreement, in the event of any (i) voluntary termination by Equity Holder of Equity Holder’s employment with Parent for Good Reason, (ii) involuntary termination of Equity Holder’s
employment with Parent by Parent without Cause, or (iii) termination of Equity Holder’s employment by reason of death or disability, before all of the Restricted Shares are released from the Repurchase Option, the Repurchase Option shall
immediately terminate and all Shares which are Unreleased Shares shall thereupon be released from the Repurchase Option. Upon request from Equity Holder, Parent shall within two business days inform the Escrow Agent immediately that the Repurchase
Option has terminated and instruct the Escrow Agent to release all Restricted Shares remaining in escrow with the Escrow Agent to Equity Holder. In the event a dispute arises between Equity Holder and Parent as to whether (x) any voluntary
resignation by Equity Holder was or was not with Good Reason or (y) whether any involuntary termination of Equity Holder’s employment was or was not 

  

 3 

 
with Cause, the Escrow Agent shall continue to hold all Restricted Shares which were Unreleased Shares at the time Equity Holder’s employment terminated
until such time as either Equity Holder and Parent resolve such dispute and jointly instruct Escrow Agent on the release of any such Restricted Shares or such dispute is resolved in accordance with the provisions of Section 7(j). 
 4. Tax Consequences. Equity Holder has reviewed with Equity Holder’s own tax advisors the federal, state, local and foreign tax consequences
of this Agreement, including the availability and consequences of an election under Section 83(b) of the Internal Revenue Code of 1986, as amended, and shall timely file such an election as to any Shares that constitute Restricted Shares (as
determined pursuant to clause (i) of the last sentence of Section 2(b)). Equity Holder is relying solely on such advisors and not on any statements or representations of Parent or any of its agents. Equity Holder understands that Equity
Holder (and not Parent) shall be responsible for Equity Holder’s own tax liability that may arise as a result of this Agreement. 
 5.
Termination. If the Merger Agreement is terminated, this Agreement shall be of no further force and effect. 
 6. General
Provisions. 
 (a) The parties hereto acknowledge that this Agreement is not an offer of securities and that the
parties’ execution of this Agreement does not indicate a commitment to buy or sell securities. By signing this Agreement, Equity Holder is not committing to vote in favor of the Merger; Equity Holder’s vote for or against the Merger will
be conducted separately. 
 (b) This Agreement may not be changed or modified, except by an agreement in writing executed by
Parent and Equity Holder. 
 (c) Any party hereto may, to the extent legally allowed, waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any agreement on the part of a party hereto to any such waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Without limiting the
generality or effect of the preceding sentence, no delay in exercising any right under this Agreement shall constitute a waiver of such right, and no waiver of any breach or default shall be deemed a waiver of any other breach or default of the same
or any other provision in this Agreement. 
 (d) All notices and other communications hereunder shall be in writing and shall
be deemed given when delivered personally, one business day after having been dispatched by a nationally recognized overnight courier service or when sent via facsimile (with acknowledgment of complete transmission) to the parties at the following
addresses (or at such other address for a party as shall be specified by like notice):

provision with a term or provision that is valid and enforceable and that comes closest to expressing the original intention of the invalid or unenforceable term or provision.

 3939 North First Street

 San Jose, California 95134 
 Attention: Corporate Secretary

 Dear                     : 
 As Escrow Agent for both SunPower Corporation (“Parent”) and
                     (“Equity Holder”), you are hereby authorized and directed to hold the documents delivered to you
pursuant to the terms of that certain Equity Restriction Agreement (the “Agreement”), dated as of the date hereof, to which a copy of these Joint Escrow Instructions is attached, in accordance with the following instructions:

 1. In the event that Parent and/or any assignee of Parent (collectively, “Parent”) exercises the Repurchase Option
(as such term is defined in the Agreement), Parent shall give to Equity Holder and you a written notice specifying the Restricted Shares (as such term is defined in the Agreement) to be purchased, the purchase price and the time for a closing
hereunder at the principal office of Parent. Equity Holder and Parent hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice. 
 2. Upon the issuance of the Restricted Shares, you are directed (a) to date the stock assignments necessary for the transfer in question,
(b) to fill in the Restricted Shares being transferred, and (c) to deliver the same, together with the certificate evidencing the Restricted Shares to be transferred, to Parent against the simultaneous delivery to you of the purchase price
(by check, by cancellation of indebtedness or by a combination thereof) for the Restricted Shares being purchased pursuant to the exercise of the Repurchase Option. 
 3. Equity Holder irrevocably authorizes Parent to deposit with you any certificates evidencing Restricted Shares to be held by you hereunder and any additions and substitutions to said shares as defined in the
Agreement. Equity Holder does hereby irrevocably constitute and appoint you as his attorney-in-fact and agent for the term of this escrow to execute with respect to such securities all documents necessary or appropriate to make such securities
negotiable and to complete any transaction herein contemplated. Subject to the provisions of this paragraph 3, Equity Holder shall exercise all rights and privileges of a stockholder of Parent while the Restricted Shares are held by you. 

4. After each successive six-month period from the date of the Agreement, unless the Repurchase Option has been exercised, you will deliver to Equity
Holder a certificate or certificates representing the Restricted Shares as are not then subject to the Repurchase Option. Promptly upon the termination of Equity Holder’s status as an employee of Parent or the death or disability (as such term
is defined in the Agreement) of Equity Holder, you will deliver to Equity Holder a certificate or certificates representing the Restricted Shares sold and issued pursuant to the Agreement and not purchased by Parent or its assignees pursuant to
exercise of the Repurchase Option. 
 5. If, at the time of termination of this escrow, you should have in your possession any documents,
securities, or other property belonging to Equity Holder, you shall deliver all of same to Equity Holder and shall be discharged of all further obligations hereunder. 
 6. Your duties hereunder may be altered, amended, modified or revoked only by a writing signed by all of the parties hereto. 
 7. You shall be obligated only for the performance of such duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by
you to be genuine and to have been signed or presented by the proper party or parties. You shall not be personally liable for any act you may do or omit to do hereunder as Escrow Agent or as attorney-in-fact for Equity Holder while acting in good
faith and in the exercise of your own good judgment, and any act done or omitted by you pursuant to the advice of your own attorneys shall be conclusive evidence of such good faith. Equity holder and Parent hereby jointly and severally indemnify you
and hold you harmless from any such liability. 
  

 8 

 8. You are hereby expressly authorized to disregard any and all warnings given by any of the parties
hereto or by any other person or corporation, excepting only orders or process of courts of law, and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case you obey or comply with any such order,
judgment or decree, you shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled,
set aside, vacated or found to have been entered without jurisdiction. 
 9. You shall not be liable in any respect on account of the
identity, authorities or rights of the parties executing or delivering or purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder. 
 10. You shall not be liable for the outlawing of any rights under any applicable statute of limitations with respect to these Joint Escrow Instructions
or any documents deposited with you. 
 11. You shall be entitled, at Parent’s expense, to employ such legal counsel and other experts
as you may deem necessary properly to advise you in connection with your obligations hereunder, may rely upon the advice of such counsel, and may pay such counsel reasonable compensation therefor. 
 12. Your responsibilities as Escrow Agent hereunder shall terminate if you shall resign by written notice to each party. In the event of any such
termination, Parent shall appoint a successor Escrow Agent. 
 13. If you reasonably require other or further instruments in connection with
these Joint Escrow Instructions or obligations in respect hereto, the necessary parties hereto shall join in furnishing such instruments. 
 14. It is understood and agreed that should any dispute arise with respect to the delivery and/or ownership or right of possession of the securities held by you hereunder, you are authorized and directed to retain in your possession without
liability to anyone all or any part of said securities until such disputes shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction, but you
shall be under no duty whatsoever to institute or defend any such proceedings. 
 15. All notices and other communications required or
permitted hereunder shall be given in accordance with Section 7(d) of the Agreement. All such notices or other communications shall be directed (i) in the case of Parent or Equity Holder, to the address, facsimile number or electronic mail
address indicated for such person on the signature page of the Agreement, or at such other address, facsimile number or electronic mail address as such party may designate by ten days’ advance written notice to the other parties hereto, and
(ii) in the case of the Escrow Agent, shall be directed to the address or facsimile number first indicated above on these Joint Escrow Instructions or at such other address or facsimile number as such party may designate by ten days’
advance written notice to the other parties hereto. 
 16. By signing these Joint Escrow Instructions, you become a party hereto only for the
purpose of said Joint Escrow Instructions; you do not become a party to the Agreement. 
 17. This instrument shall be binding upon and inure
to the benefit of the parties hereto, and their respective successors and permitted assigns. 
 18. This instrument may be executed in one or
more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. Facsimile copies of signed signature pages shall be binding originals.

	1.	Interest 

 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 February 1 and August 1 of each year, commencing August 1, 2007. 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             , 2007 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 shall pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	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 January 15 or July 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). 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 (including principal, premium, if any, and 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. 
  

	4.	Indenture 

 The Issuers issued the Securities under
an Indenture dated as of July 21, 2006 (the “Indenture”), among Chase Merger Sub, Inc., a Delaware corporation and the Trustee and by a Supplemental Indenture dated as of July 21, 2006, among the Issuers, the Trustee and 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 Exchange Securities referred to in the Indenture. The Securities include the Initial Securities, any Additional Securities and any Exchange Securities issued in exchange for the Initial
Securities or any Additional Securities pursuant to the Indenture. The Initial Securities, any Additional 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

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.

	 	Holders upon Change of Control and Asset Sales

effectively subordinated to any Secured Indebtedness to the extent of the value of the assets securing such Secured Indebtedness, as defined in the Indenture. The Issuers and each Guarantor agree, and each Holder by accepting a Security agrees, to
the subordination provisions contained in the Indenture and authorizes the Trustee to give it effect and appoints the Trustee as attorney-in-fact for such purpose. 
  

	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

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.

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 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.

(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 Notes; (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 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 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.
