 “Acquired Debt” means Indebtedness (1) of a Person or any of its Subsidiaries existing at the time such Person
becomes a Restricted Subsidiary, or (2) assumed in connection with the acquisition of assets from such Person, in each case whether or not incurred by such Person in connection with or in contemplation of such Person becoming a Restricted
Subsidiary of the Parent or such acquisition or (3) of a Person at the time such Person merges with or into or consolidates or otherwise combines with the Parent or any Restricted Subsidiary. Acquired Debt will be deemed to have been incurred,
with respect to clause (1) of the preceding sentence, on the date such Person becomes a Restricted Subsidiary and, with respect to clause (2) of the preceding sentence, on the date of consummation of such acquisition of assets and, with
respect to clause (3) of the preceding sentence, on the date of the relevant merger, consolidation or other combination. 

“Additional Notes” means additional Notes (other than the Initial Notes) issued under this Indenture in accordance with

 “Applicable Laws” means, as to any Person, any law,
rule, regulation, ordinance or treaty, or any determination, ruling or other directive by or from a court, arbitrator or other governmental authority, including any independent system operator, or any other entity succeeding thereto, in each case

“Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global Note,
the rules and procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange.

(1)    1.0% of the principal amount of the Note; and

at such redemption date plus 50 basis points discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months); over

 (b) the outstanding principal amount of the Note, as calculated by the Issuer or an agent appointed by the Issuer. 

For the avoidance of doubt, calculations of, or verification of the Issuer’s calculations of, the Applicable Redemption
Premium shall not be a duty or obligation of the Trustee or any Paying Agent. 
 “Asset Sale” means: 

(1)    the sale, lease, transfer, conveyance or other disposition of any assets by the Parent or any of its
Restricted Subsidiaries outside of the ordinary course of business; provided, however, that the sale, lease, transfer, conveyance or other disposition of all or substantially all of the assets of the Parent and its Restricted Subsidiaries taken as a

ARTICLE 2 
 THE NOTES 

Section 2.01    Form and Dating. 

(a)    General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of
Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. 
 The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a
part of this Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note
conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 

(b)    Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including
the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note
Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents
the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect
exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction
of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 

(c)    Initial Notes. Initial Notes offered and sold in reliance on Rule 144A will be issued initially in the form
of one or more 144A Global Notes, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as Custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary,
duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. Initial Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Global Note, which will be deposited on behalf
of the purchasers of the Notes represented thereby with the Trustee, as 

  
 31 

 
Custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream,
duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. 
 (d)    Euroclear and
Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of
Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Global Note that are held by Participants through Euroclear or Clearstream. 

Section 2.02    Execution and Authentication. 

At least one Officer must sign the Notes for the Issuer by manual, facsimile or other electronic signature. 

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be
valid. 
 A Note will not be valid until authenticated by the manual signature of an authorized signatory of the Trustee. The signature will
be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a written order of
the Issuer signed by an Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes up to the aggregate principal amount stated in such
Authentication Order for such Additional Notes issued hereunder (it being understood that, notwithstanding anything to the contrary contained in this Indenture, no Opinion of Counsel pursuant to Section 12.02 will be required by the Trustee
with the authentication of the Initial Notes on the Issue Date). The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuer pursuant to one or more
Authentication Orders, except as provided in Section 2.08 hereof. 
 Additional Notes may be issued from time to time subject to the
terms of this Indenture, including Section 4.09. The Initial Notes and the Additional Notes shall be treated as a single class for all purposes of this Indenture, including, without limitation, waivers, amendments, redemptions and offers to
purchase, and Additional Notes shall have identical terms and conditions as the Initial Notes, other than (i) the date of issuance and (ii) if applicable, the first Interest Payment Date and date from which interest will begin to accrue;
provided however that if any Additional Notes are not fungible with the Initial Notes for U.S. federal income tax or other purposes, such Additional Notes will have a separate CUSIP number. 

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes
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 an Agent to deal with Holders or an Affiliate of the Issuer. 

  
 32 

 Section 2.03    Registrar and Paying Agent. 

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

Section 2.04    Paying Agent to Hold Money in Trust. 

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit
of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest, if any, on, the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent
(if other than the Issuer or a Subsidiary) will have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as
Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes. 

Section 2.05    Holder Lists. 

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
all Holders. If the Trustee is not the Registrar, the Issuer will furnish to the Trustee at least seven 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 the Holders. 

Section 2.06    Transfer and Exchange. 

(a)    Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any 

  
 33 

 
such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuer for Definitive Notes if: 

(1)    the Issuer delivers to the Trustee notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 90 days after the date of such notice from the Depositary; or

 (2)    the Issuer in its sole discretion determines that the Global Notes (in whole but not in part)
should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee. 
 Upon the occurrence of either of
the preceding events in (1) or (2) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and
2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of,
and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b)
or (c) hereof. 
 (b)    Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and
exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes will be subject to
restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as
applicable, as well as one or more of the other following subparagraphs, as applicable: 

(1)    Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any
Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend. Beneficial
interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the
Registrar to effect the transfers described in this Section 2.06(b)(1). 
 (2)    All Other
Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(1) above, the transferor of such beneficial interest must
deliver to the Registrar either: 
 (A)    both: 

(i)    a written order from a Participant or an Indirect Participant given to the Depositary in accordance
with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

  
 34 

 (ii)    instructions given in accordance with the
Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above. 
 Upon satisfaction of all of the

pursuant to Section 2.06(g) hereof. 
 (3)    Transfer of Beneficial Interests to
Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer
complies with the requirements of Section 2.06(b)(2) above and the Registrar receives the following: 

(A)    if the transferee will take delivery in the form of a beneficial interest in the 144A Global Note,
then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof;

(4)    Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial
Interests in an Unrestricted Global Note. A beneficial interest in any Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof
in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer 

  
 35 

 complies with the requirements of Section 2.06(b)(2) above and the
Registrar receives the following:

Securities Act. 
 If any such transfer is effected pursuant to this subparagraph (4) at a time when an Unrestricted Global Note has
not yet been issued, the Issuer shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the
aggregate principal amount of beneficial interests transferred pursuant to this subparagraph (4). 
 Beneficial interests in an

(2)    Global Note Legend. Each Global Note will bear a legend in substantially the following form:

 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE
BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE, (2) THIS GLOBAL NOTE MAY

 (g)    Cancellation and/or Adjustment of Global Notes. At such time as all beneficial
interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the
Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the
Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased
accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 

(h)    General Provisions Relating to Transfers and Exchanges. 

(1)    To permit registrations of transfers and exchanges, the Issuer will execute and the Trustee will
authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

(2)    No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder
of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer Tax or similar governmental charge payable in connection therewith (other than any such transfer Taxes or
similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof). 

(3)    The Registrar will not be required to register the transfer of or exchange of any Note selected for
redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

(4)    All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global
Notes or Definitive Notes will be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or
exchange. 
 (5)    Neither the Registrar nor the Issuer will be required: 

(A)    to issue, to register the transfer of or to exchange any Notes during a period beginning at the
opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 

  
 44 

 (B)    to register the transfer of or to exchange any
Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 

(C)    to register the transfer of or to exchange a Note between a record date and the next succeeding
Interest Payment Date. 
 (6)    Prior to due presentment for the registration of a transfer of any Note,
the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and (subject to the record date provisions of the Notes)
interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary. 

(7)    The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of
Section 2.02 hereof. 
 (8)    All certifications, certificates and any Opinion of Counsel required
to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 

(9)    The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or Beneficial Owners of interests in any Global Note)
other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial
compliance as to form with the express requirements hereof. 
 Neither the Trustee nor any Agent shall have any responsibility for any
actions taken or not taken by the Depositary. The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, any Participant in the Depositary or any other Person with respect to the accuracy of the records of the
Depositary or its nominee or of any Participant thereof, with respect to any ownership interest in Global Notes or with respect to the delivery to any Participant, beneficial owner or other Person (other than the Depositary) of any notice (including
any notice of redemption or purchase) or the payment of any amount, under or with respect to such Global Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Global Notes shall be given or
made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the
applicable rules and procedures of the Depositary. The Trustee may rely conclusively and shall be fully protected in relying upon information furnished by the Depositary with respect to its Participants and any beneficial owners. 

  
 45 

 Section 2.07    Replacement Notes. 

If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction,
loss or theft of any Note, the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond
must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer
may charge for its expenses in replacing a Note. 
 In case any such mutilated, destroyed, lost or stolen Note has become or is about to
become due and payable, the Issuer in its discretion may, instead of issuing a new Note, pay such Note. 
 Every replacement Note is an
additional obligation of the Issuer and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 

Section 2.08    Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer shall not be deemed to be outstanding for purposes of Section 3.07(b) hereof.

 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to
it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Issuer, a
Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue
interest. 
 Section 2.09    Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by
the Issuer or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor, will be considered as though not outstanding, except that for the purposes
of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 

  
 46 

 Section 2.10    Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order,
will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without
unreasonable delay, the Issuer will prepare and the Trustee will authenticate Definitive Notes in exchange for temporary Notes. 
 Holders
of temporary Notes will be entitled to all of the benefits of this Indenture. 

Section 2.11    Cancellation. 

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of canceled Notes
(subject to the record retention requirements of the Exchange Act) in accordance with its customary procedures. Certification of the cancellation of all canceled Notes will be delivered to the Issuer upon request. The Issuer may not issue new Notes
to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 

Section 2.12    Defaulted Interest. 

If the Issuer defaults in a payment of interest on the Notes, to the extent permitted by any Applicable Laws, it will pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof,
provided that no special record date shall be required with respect to defaulted interest that is paid within the applicable grace period. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each
Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such
defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will mail or cause to be mailed (or, in the case of Global Notes,
transmit with the procedures of the Depositary) to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

ARTICLE 3 
 REDEMPTION AND
PREPAYMENT 
 Section 3.01    Notices to Trustee. 

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the
Trustee, at least five Business Days (or such shorter period as shall be satisfactory to the Trustee) prior to the giving notice of a redemption, an Officer’s Certificate setting forth: 

(1)    the clause of this Indenture pursuant to which the redemption shall occur; 

  
 47 

 (2)    the redemption date; 

(3)    the principal amount of Notes to be redeemed; and 

(4)    the redemption price or the method by which it is to be determined. 

Section 3.02    Selection of Notes to Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a by lot basis (or, in the
case of Notes issued in global form, based on a method that most nearly approximates a by lot selection) unless otherwise required by law or applicable stock exchange requirements; provided, however, that so long as DTC serves as a
Depositary for Notes issued in global form, any redemption will comply with the applicable procedural requirements of DTC with respect to redemption. 

The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in minimum amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for
redemption. 
 Section 3.03    Notice of Redemption. 

Subject to the provisions of Section 3.09 hereof, at least 10 days but not more than 60 days before a redemption date, the Issuer will
mail or cause to be mailed, by first class mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary), a notice of redemption to each Holder (with a copy to the Trustee) whose Notes are to be redeemed at its
registered address, except that redemption notices may be mailed or transmitted more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture
pursuant to Articles 8 or 11 hereof. 
 The notice will identify the Notes to be redeemed and will state: 

(1)    the redemption date; 

(2)    the redemption price, or if not then ascertainable, the manner of calculation thereof; 

(3)    if any Note is being redeemed in part, the portion of the principal amount of such Note to be
redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 

(4)    the name and address of the Paying Agent; 

  
 48 

 (5)    that Notes called for redemption must be
surrendered to the Paying Agent to collect the redemption price; 
 (6)    that, unless the Issuer
defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 

(7)    the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for
redemption are being redeemed; 
 (8)    that no representation is made as to the correctness or accuracy
of the CUSIP number, if any, listed in such notice or printed on the Notes; and 
 (9)    any conditions
precedent to which the redemption is subject. 
 At the Issuer’s written request, the Trustee will give the notice of redemption in the
Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least 30 days (or such shorter period as shall be satisfactory to the Trustee) prior to the redemption date, an Officer’s
Certificate requesting that the Trustee give such notice and setting forth the form of the notice to be provided. 
 Any such redemption
may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of any related Equity Offering, Change of Control or other transaction. In addition, if such redemption is subject to the satisfaction of one
or more conditions precedent, the related notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be
satisfied or waived, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption date as so delayed. In addition,
the Issuer may provide in such notice that payment of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person (it being understood that any such provision for payment
by another Person will not relieve the Issuer and the Guarantors from their obligations with respect to such redemption). 

Section 3.04    Effect of Notice of Redemption. 

Once notice of redemption is delivered or mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably
due and payable on the redemption date at the redemption price, subject to the fourth paragraph of Section 3.03. 

Section 3.05    Deposit of Redemption Price. 

No later than 11:00 a.m. Eastern Time on the redemption date, the Issuer will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued and unpaid interest, if any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying Agent
by the Issuer in excess of the amounts necessary to pay the redemption price of and accrued and unpaid interest, if any, on all Notes to be redeemed. 

  
 49 

 Unless the Issuer defaults in the payment of the redemption price, interest will cease to
accrue on the Notes or portions thereof called for redemption on the applicable redemption date. If a Note is redeemed on or after an interest record date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest
shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption is not so paid upon surrender for redemption because of the failure of the Issuer to comply with the
preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01 hereof. 
 Section 3.06    Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Issuer will issue and, upon receipt of an Authentication Order, the Trustee will
authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 

Section 3.07    Optional Redemption. 

(a)    Except as described below, the Notes will not be redeemable at the Issuer’s option prior to September 1,
2023. 
 (b)    At any time prior to September 1, 2023, the Issuer may on any one or more occasions redeem up to
40% of the aggregate principal amount of Notes issued under this Indenture (including any Additional Notes), upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 105.875% of the principal amount of the Notes
redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date with an amount not to exceed the amount of net cash proceeds of one or more Equity Offerings consummated after the Issue Date; provided that: 

(1)    at least 50% of the aggregate principal amount of Notes issued under this Indenture (including
Additional Notes but excluding Notes held by the Issuer and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption (unless all such Notes are otherwise being repurchased or redeemed substantially concurrently
pursuant to another provision described under this Section 3.07); and 
 (2)    the redemption
occurs within 180 days of the date of the closing of such Equity Offering. 
 (c)    At any time prior to
September 1, 2023, the Issuer may on any one or more occasions redeem all or any part of the Notes upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus
the Applicable Redemption Premium as of, and accrued and unpaid interest, if any, to, but excluding, the date of redemption. 

(d)    On or after September 1, 2023, the Issuer may on any one or more occasions redeem all or any part of the
Notes, upon not less than 10 nor more than 60 days’ notice, at the redemption prices (expressed as a percentage of principal amount of the Notes) set forth below, plus accrued 

  
 50 

 
and unpaid interest, if any, to, but excluding, the applicable redemption date, if redeemed during the twelve-month period beginning on September 1 of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2023
	  	 	102.938	% 
	 2024
	  	 	101.469	% 
	 2025 and thereafter
	  	 	100.000	% 

 (e)    If Holders of not less than 90% in aggregate principal amount of the outstanding
Notes properly tender such Notes pursuant to a Change of Control Offer or any cash tender offer for all of the outstanding Notes and the Issuer, or any third party making a Change of Control Offer or other cash tender offer in lieu of the Issuer,
purchases all of the Notes properly tendered by such Holders, the Issuer or such third party will have the right, upon not less than 10 nor more 60 days prior notice, given not more than 30 days following such purchase pursuant to the Change of
Control Offer or other cash tender offer, to redeem all Notes that remain outstanding following such purchase at a cash price equal to the price offered to each other holder in the Change of Control Offer or other tender offer payment (excluding any
early tender, incentive or similar fee), plus to the extent not included in the Change of Control Offer or other tender payment, accrued and unpaid interest, if any, on the Notes that remain outstanding to, but excluding, the date of redemption.

 (f)    Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof. 
 Section 3.08    Mandatory Redemption; Offers to Purchase; Purchase of
Notes. 
 The Issuer will not be required to make any mandatory redemption or sinking fund payments with respect to the Notes. However,
under certain circumstances, the Issuer may be required to offer to purchase the Notes as described under Section 4.10 and Section 4.15. The Parent, the Restricted Subsidiaries and their respective Affiliates may at any time and from time
to time purchase the Notes in the open market, by tender offer, in negotiated transactions or otherwise. 

Section 3.09    Offer to Purchase by Application of Excess Proceeds. 

In the event that, pursuant to Section 4.10 hereof, the Issuer is required to commence an offer to all Holders to purchase Notes (an
“Asset Sale Offer”), it will follow the procedures specified below. 
 The Asset Sale Offer shall be made to all Holders
and all holders of other Pari Passu Indebtedness containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for
a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days
after the termination of the Offer Period (the “Purchase Date”), the Issuer will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Pari Passu Indebtedness (on a pro rata
basis based on the principal amount 

  
 51 

 
of Notes and such other Pari Passu Indebtedness surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Pari Passu Indebtedness tendered in response
to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 If the
Purchase Date is on or after an interest record date and on or before the related Interest Payment Date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record
date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of
an Asset Sale Offer, the Issuer will send, by first class mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary), a notice to each of the Holders, with a copy to the Trustee. The notice will contain all
instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state: 

(1)    that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10
hereof and the length of time the Asset Sale Offer will remain open; 
 (2)    the Offer Amount, the
purchase price and the Purchase Date; 
 (3)    that any Note not tendered or accepted for payment will
continue to accrue interest; 
 (4)    that, unless the Issuer defaults in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date; 

(5)    that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have
Notes purchased in minimum denominations of $2,000 or an integral multiple of $1,000 in excess thereof; 

(6)    that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to
surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Issuer, a Depositary, if appointed by the Issuer, or a Paying Agent at the
address specified in the notice at least three days before the Purchase Date; 
 (7)    that Holders will
be entitled to withdraw their election if the Issuer, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of
the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

(8)    that, if the aggregate principal amount of Notes and other Pari Passu Indebtedness surrendered by
holders thereof exceeds the Offer Amount, the Issuer will select the Notes and other Pari Passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other Pari Passu Indebtedness surrendered

  
 52 

 
(with such adjustments as may be deemed appropriate by the Issuer so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased);
and 
 (9)    that Holders whose Notes were purchased only in part will be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
 On or before the Purchase
Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been
tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in
accordance with the terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than two Business Days after the Purchase Date) mail or deliver to each tendering

mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to
the Holder thereof. The Issuer will publicly announce the results of the Asset Sale Offer on or as soon as practicable after the Purchase Date.

 COVENANTS 

Section 4.01    Payment of Notes. 

The Issuer will pay or cause to be paid the principal of, premium on, if any, and interest, if any, on, the Notes on the dates and in the
manner provided in the Notes. Principal, premium, if any, and interest, if any, will be considered paid on the date due if the Paying Agent, if other than the Issuer or a Subsidiary thereof, holds as of 11:00 a.m. Eastern Time on the due date money

Section 4.02    Maintenance of Office or Agency. 

The Issuer will maintain an office or agency (which may be an office of the Trustee or an Affiliate of the Trustee, Registrar or co-registrar)
where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer will 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 Issuer fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Trustee; provided that no office of the Trustee shall be an office or agency of the Issuer for purposes of service of legal process on the Issuer or any Guarantor. 

  
 53 

 The Issuer may also from time to time designate one or more other offices or agencies where
the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Issuer will 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. 
 The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or
agency of the Issuer in accordance with Section 2.03 hereof. 
 Section 4.03    Reports. 

(a)    So long as any Notes are outstanding, the Parent will file with the SEC or make publicly available on a website,
within the time periods (including any extensions thereof) specified in the SEC’s rules and regulations: 

(1)    all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Parent were required to file such reports as a non-accelerated filer; and 

(2)    all current reports that would be required to be filed with the Commission on Form 8-K if the Parent were required to file such reports. 
 Notwithstanding any of the foregoing, at any time
when the Parent does not otherwise file such reports with the Commission, (a) no certifications, reports or attestations concerning the financial statements, disclosure controls and procedures or internal controls that would otherwise be
required pursuant to the Sarbanes-Oxley Act of 2002, as amended, and the SEC rules and regulations implementing that Act, will be required; (b) no financial schedules specified in Regulation S-X under the
Securities Act will be required; (c) compliance with the requirements of Item 10(e) of Regulation S-K under the Securities Act will not be required; (d) information specified in Rules 13-01 and 13-02 of Regulation S-X under the Securities Act with respect to Subsidiaries and Affiliates will not be required; and
(e) no exhibits pursuant to Item 601 of Regulation S-K under the Securities Act will be required. 

(b)    In addition, the Issuer, the Parent and the Subsidiary Guarantors agree that, for so long as any Notes remain
outstanding, at any time they are not required to file the reports required by this Section 4.03 with the SEC, they will furnish to the Trustee, Holders and to securities analysts and bona fide prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 (c)    Delivery of any
such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable
from information contained therein, including the Parent’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). Further, the Trustee shall have no
obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the SEC’s EDGAR filing system (or its successor) or made publicly available on a website. 

  
 54 

 (d)    At any time that any of the Parent’s Unrestricted
Subsidiaries would be a Significant Subsidiary, then the quarterly and annual financial information required by Section 4.03(a) will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes
thereto or in a separate discussion (which may be contained in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of the applicable quarterly or annual report), of the financial
condition and results of operations of the Parent and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Parent. 

Section 4.04    Compliance Certificate. 

(a)    The Issuer and each Guarantor shall deliver to the Trustee, within 90 days after the end of each fiscal year, an
Officer’s Certificate stating that a review of the activities of the Parent and the Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer (who shall be a member of senior management)
with a view to determining whether the Parent and the Restricted Subsidiaries has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to such Officer signing such certificate, that to his or her
knowledge, the Parent and the Restricted Subsidiaries has kept, observed, performed and fulfilled each and every covenant contained in this Indenture (without regards to periods of grace or notice requirements) and is not in default in the
performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action
the Parent and the Restricted Subsidiaries is taking or proposes to take with respect thereto). 
 (b)    So long as any
of the Notes are outstanding, the Issuer and the Parent will deliver to the Trustee, within five Business Days of any of their Officers becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event
of Default and what action the Issuer and the Parent are taking or propose to take with respect thereto, but only to the extent such Default or Event of Default has not been cured by the end of such five Business Day period. The Trustee will not be
deemed to have knowledge of any Defaults or Events of Default unless written notice of an event, which is in fact a Default, has been delivered to the Trustee at its Corporate Trust Office and such notice references the Notes and this Indenture and
states that it is a “Notice of Default.” 
 Section 4.05    Taxes. 

The Parent will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material Taxes, assessments, and governmental
levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders. 

Section 4.06    Stay, Extension and Usury Laws. 

The Issuer and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or
in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter 

  
 55 

 
in force, that may affect the covenants or the performance of this Indenture; and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though
no such law has been enacted. 
 Section 4.07    Limitation on Restricted Payments. 

(a)    The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 

(1)    declare or pay any dividend or make any other payment or distribution on account of the
Parent’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Parent or its Restricted Subsidiaries) or to the direct or indirect
holders of the Parent’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as holders (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Parent or any of its
Restricted Subsidiaries and other than dividends or distributions payable to the Parent or its Restricted Subsidiaries); 

(2)    purchase, redeem or otherwise acquire or retire for value (including, without limitation, in
connection with any merger or consolidation involving the Issuer) any Equity Interests of the Parent or any direct or indirect parent entity of the Parent other than Equity Interests held by the Parent or any of its Restricted Subsidiaries; 

(3)    make any payment on, or purchase, repurchase, redeem, defease or otherwise acquire or retire for

payment of interest or principal at the Stated Maturity thereof or (ii) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of any subordinated Indebtedness in anticipation of satisfying a sinking fund
obligation, principal installment or payment at final maturity, in each case due within one year of the date of purchase, repurchase, redemption, defeasance or other acquisition or retirement for value); or 

(4)    make any Restricted Investment in any Person, 

(all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted
Payments”), 
 unless, at the time of any such Restricted Payment: 

(i)    no Default (except a Reporting Default) or Event of Default has occurred and is continuing or would
occur as a consequence of such Restricted Payment, 
 (ii)    the Parent would, at the time of such
Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable Test Period have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed
Charge Coverage Ratio test set forth in Section 4.09(a), and 

  
 56 

 (iii)    such Restricted Payment, together with the
aggregate amount of all other Restricted Payments made by the Parent and its Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by clauses (2) through (12) of Section 4.07(b)), is less than the sum,
without duplication, of: 
 (A)    50% of Cumulative CAFD, determined as of the date such Restricted
Payment is made; plus

Business) since the Issue Date (x) as a contribution to its common equity capital or (y) in consideration of the sale or issuance of Equity Interests of the Parent (other than Disqualified Stock) or from the issue or sale of convertible or

indirect parent of the Parent (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Parent) or, in each case not involving cash consideration payable by the Parent in connection with any such
transaction, that becomes a part of the capital of the Parent through consolidation, merger or amalgamation following the Issue Date; plus 

(C)    to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or
otherwise liquidated or repaid for cash, 100% of the aggregate amount received by the Parent or its Restricted Subsidiaries in cash and the Fair Market Value of property other than cash received; plus 

(D)    the net reduction in Restricted Investments after the Issue Date resulting from dividends,
liquidating distributions, redemptions, repayments of loans or advances, or other transfers of assets in each case to the Parent or any of its Restricted Subsidiaries from any Person (including, without limitation, Unrestricted Subsidiaries and
Joint Ventures) and the Fair Market Value of each Restricted Investment in each Subsidiary designated as an Unrestricted Subsidiary after the Issue Date and later redesignated as a Restricted Subsidiary, in the case of each of the foregoing items
(B), (C) and (D) for purposes of this clause (iii), to the extent such amounts have not been included in Cumulative CAFD for any period commencing on or after the Issue Date. 

  
 57 

 (b)    The preceding provisions will not prohibit: 

(1)    the payment of any dividend or the consummation of any redemption within 60 days after the date of
declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with this Indenture; 

(2)    the making of any Restricted Payment in exchange for, or out of or with the net cash proceeds of the
substantially concurrent sale or issuance (other than to a Subsidiary of the Parent) of, Equity Interests of the Parent (other than Disqualified Stock), or from the substantially concurrent contribution to the common equity capital of the Parent
(other than from a Subsidiary of the Parent); provided that the amount of any net cash proceeds that are utilized for any such Restricted Payment will not be considered net proceeds from the sale of Equity Interests for the purpose of

any calendar year (with unused amounts in any calendar year being carried over to succeeding calendar years); and provided further, that such amount in any calendar year may be increased by an amount not to exceed the cash proceeds from
(i) the sale of Equity Interests of the Parent or the Issuer received by the Parent or a Restricted Subsidiary during such calendar year, in each case to members of management, directors or consultants of the Parent, any of its Restricted
Subsidiaries or the Issuer and (ii) key man life insurance policies received by the Parent or any of its Restricted Subsidiaries in such calendar year; 

(4)    the defeasance, redemption, repurchase, repayment or other acquisition of subordinated Indebtedness

accordance with Section 4.09; 
 (9)    payments of cash, dividends, distributions, advances or

clause (12) not to exceed the greater of (i) $75.0 million or (ii) 2.0% of Consolidated Total Assets determined as of each date a Restricted Payment is made pursuant to this clause (12).

Investment, the Issuer will be able to classify or later reclassify (based on circumstances existing on the date of such reclassification) such Restricted Payment (or a portion thereof) between such clauses (1) through (12) of
Section 4.07(b) and Section 4.07(a) or as a Permitted Investment in any manner that otherwise complies with this Section 4.07.

affect the Parent’s ability to make principal and interest payments on the Notes as and when they fall due; or (y) such encumbrances and restrictions apply only during the continuance of a default in respect of a payment or financial
maintenance covenant relating to such Indebtedness;

(including Acquired Debt), and the Parent will not issue any Disqualified Stock and will not permit its Restricted Subsidiaries to issue any Disqualified Stock or Preferred Equity; provided, however, that the Parent and its Restricted
Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any Restricted Subsidiary may issue Preferred Equity, if on the date of incurrence or issuance thereof the Fixed Charge Coverage Ratio for the applicable
Test Period would have been at least 2.0 to 1.0, 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 the Preferred Equity
had been issued, as the case may be, on the first day of the relevant Test Period. 

  
 62 

 (b)    Section 4.09(a) will not prohibit the incurrence of any of

respect of Indebtedness outstanding pursuant to this clause (4)), will not to exceed the greater of (A) $50.0 million or (B) 1.5% of Consolidated Total Assets determined as of each date of incurrence pursuant to this clause (4); 

(5)    Indebtedness of the Parent owing to any of its Restricted Subsidiaries or Indebtedness of any of its

Parent or a Restricted Subsidiary and (B) any transfer of such Indebtedness to a Person that is not the Parent or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Parent or such
Restricted Subsidiary, as the case may be, that was not permitted by this clause (5); 
 (6)    the
issuance by any of the Parent’s Restricted Subsidiaries to the Parent or to any of its Restricted Subsidiaries of shares of Preferred Equity; provided, however, that: (A) any subsequent issuance or transfer of Equity
Interests that results in any such Preferred Equity being held by a Person other than the Parent or a Restricted Subsidiary of the Parent; and (B) any sale or other transfer of any such Preferred Equity to a Person that is not either the Parent

(7)    Indebtedness or Disqualified Stock of the Parent or Indebtedness or Preferred Equity of a Restricted
Subsidiary incurred and outstanding on the date on which such Restricted Subsidiary was directly or indirectly acquired by the Parent after the Issue Date or on the date it otherwise becomes a Restricted Subsidiary (in either case, whether or not
such Indebtedness, Disqualified Stock or Preferred Equity was incurred in contemplation of such acquisition); provided that, that after giving effect to such 

  
 63 

 
acquisition and incurrence, either (A) the Parent would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.09(a) or (B) the Fixed Charge Coverage Ratio for the applicable Test Period would be equal to or greater than immediately prior to such acquisition and incurrence;

Consolidated Total Assets and (ii) Indebtedness constituting reimbursement obligations with respect to letters of credit, bankers’ acceptances or similar instruments or obligations issued in the ordinary course of business; provided

Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the guarantee will be subordinated or pari passu, as applicable, to the same
extent as the Indebtedness guaranteed; and (ii) any Non-Recourse Subsidiary of Indebtedness (including any Non-Recourse Financing) of any other Non-Recourse Subsidiary; 
 (15)    (i) the factoring of accounts
receivable and (ii) reverse factoring or confirming of accounts payable, in each case arising in the ordinary course of business; 

  
 64 

 (16)    Indebtedness that constitutes Non-Recourse Financing that is incurred by a Non-Recourse Subsidiary and Preferred Equity issued by a Non-Recourse Subsidiary

(20)    Indebtedness of the Parent and its Restricted Subsidiaries in an aggregate outstanding principal
amount as of the date of any incurrence pursuant to this clause (20) which, when taken together with the principal amount of all other Indebtedness incurred pursuant to this clause (20) and then outstanding (and any Refinancing
Indebtedness in respect of Indebtedness that is then outstanding), will not exceed the greater of (i) $75.0 million or (ii) 2.0% of Consolidated Total Assets, determined as of the date of each incurrence pursuant to this clause (20); 

(21)    the guarantee by the Parent or any of its Restricted Subsidiaries of Indebtedness of any

Consolidated Total Assets determined as of the date of each incurrence pursuant to this clause (21); 

(22)    the incurrence of Indebtedness by the Parent or any Restricted Subsidiary to the extent that the

Indebtedness permitted under Section 4.09(a) or clauses (2), (3), (4), (7) or (20) of this Section 4.09(b). 
 The Issuer and the Guarantors
will not incur any Indebtedness (other than intercompany Indebtedness incurred pursuant to clause (5) of this Section 4.09(b)) that is contractually subordinated in right of payment to any other Indebtedness of the Issuer or the applicable
Guarantor, unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that (i) no Indebtedness will be deemed
to be contractually subordinated in right of payment to any other Indebtedness of the Issuer or the Guarantors solely by virtue of being unsecured or by virtue of being secured on a junior priority basis and (ii) (if the Parent shall so determine)
any 

  
 65 

 
Indebtedness incurred pursuant to clause (20) of this Section 4.09(b) shall cease to be deemed incurred or outstanding for purposes of such clause but shall be deemed incurred for the
purposes of Section 4.09(a) from and after any date designated by the Parent on which the Parent or any Restricted Subsidiary could have incurred such Indebtedness under Section 4.09(a) without reliance on such clause. 

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of
more than one of the categories described in paragraphs (b)(1) through (24) of this Section 4.09, or is entitled to be incurred pursuant to paragraph (a) of this Section 4.09, the Issuer will be permitted to classify such item of
Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. 

The accrual of interest or Preferred Equity dividends, the accretion or amortization of original issue discount, the payment of interest on
any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Preferred Equity as Indebtedness due to a change in accounting principles, and the payment of dividends on Preferred Equity or Disqualified Stock in
the form of additional shares of the same class of Preferred Equity or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Equity or Disqualified Stock for purposes of this Section 4.09. 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 utilized, calculated based on
the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Parent or any Restricted Subsidiary may incur
pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 

For purposes of determining compliance with this Section 4.09, the amount of any Indebtedness outstanding as of any date will be: 

(1)    the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue
discount; 
 (2)    the principal amount of the Indebtedness, in the case of any other Indebtedness; and

 (3)    in respect of Indebtedness of another Person secured by a Lien on the assets of the specified
Person, the lesser of: 
 (A)    the Fair Market Value of such assets at the date of determination; and

 (B)    the amount of the Indebtedness of the other Person. 

With respect to any acquisition of a Permitted Business or long-term assets used or useful in a Permitted Business (whether by merger,
consolidation or other business combination or the acquisition of Capital Stock), for purposes of determining whether: 

(1)    any Indebtedness (including Acquired Debt) that is being incurred in connection with such
acquisition is permitted to be incurred in compliance with this Section 4.09; and 

  
 66 

 (2)    whether any Lien being incurred to secure any
such Indebtedness is permitted to be incurred in accordance with Section 4.12, 
 any calculation of the Fixed Charge Coverage Ratio, Consolidated
Total Assets or CFADS may be made, at the option of the Parent, using the date that the definitive agreement for such acquisition is entered into (the “Acquisition Agreement Date”) as the applicable date of determination of the
Fixed Charge Coverage Ratio, Consolidated Total Assets or CFADS, as the case may be, in each case with such pro forma adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of “Fixed
Charge Coverage Ratio.” For the avoidance of doubt, if the Parent elects to use the Acquisition Agreement Date as the applicable date of determination in accordance with the foregoing, any fluctuation or change in the Fixed Charge Coverage
Ratio, CFADS or Consolidated Total Assets of the Parent or the Permitted Business or assets to be acquired subsequent to the Acquisition Agreement Date and prior to the consummation of such acquisition will not be taken into account for purposes of
determining whether any Indebtedness (including Acquired Debt) that is being incurred in connection with such acquisition is permitted to be incurred in compliance with this Section 4.09, or whether any Lien being incurred to secure any such
Indebtedness is permitted to be incurred in accordance with Section 4.12, but any Indebtedness, Investment or other transaction that is required to be given pro forma effect in accordance with the applicable adjustment provisions described
above incurred or consummated after the Acquisition Agreement Date and on or prior to the consummation of such acquisition will be taken into account. 

If any Indebtedness is incurred, or Disqualified Stock or Preferred Stock is issued, in reliance on a basket measured by reference to a
percentage of Consolidated Total Assets or an amount of CFADS, and any refinancing thereof would cause the percentage of Consolidated Total Assets or amount of CFADS, as applicable, to be exceeded if calculated based on the Consolidated Total Assets
or CFADS, as applicable, on the date of such refinancing, such percentage of Consolidated Total Assets or amount of CFADS, as applicable, will not be deemed to be exceeded to the extent the principal amount of such newly incurred Indebtedness, the
liquidation preference of such newly issued Disqualified Stock or the amount of such newly issued Preferred Stock does not exceed the sum of (i) the principal amount of such Indebtedness, the liquidation preference of such Disqualified Stock or
the amount of such Preferred Stock being refinanced, extended, replaced, refunded, renewed or defeased plus (ii) any accrued and unpaid interest on the Indebtedness, any accrued and unpaid dividends on the Preferred Stock and any accrued and
unpaid dividends on the Disqualified Stock being so refinanced, extended, replaced, refunded, renewed or defeased plus (iii) the amount of any tender premium or penalty or premium required to be paid under the terms of the instrument or
documents governing such refinanced Indebtedness, Preferred Stock or Disqualified Stock and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar fees) incurred in connection with the issuance of
such new Indebtedness, Preferred Stock or Disqualified Stock or the extension, replacement, refunding, refinancing, renewal or defeasance of such refinanced Indebtedness, Preferred Stock or Disqualified Stock.

 Section 4.10    Limitation on Sales of Assets. 

(a)    The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate
an Asset Sale unless: 
 (1)    the Parent (or the relevant Restricted Subsidiary, as the case may be)
receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement in connection with such Asset Sale) of the assets or Equity Interests issued or sold or otherwise
disposed of; 
 (2)    at least 75% of the consideration received in the Asset Sale and all other Asset
Sales since the Issue Date (on a cumulative basis) by the Parent or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (2), each of the following will be deemed to be cash: 

(A)    any liabilities, as recorded on the balance sheet of the Parent or any Restricted Subsidiary (other
than contingent liabilities), that are assumed or discharged by the transferee of any such assets and as a result of which the Parent and its Restricted Subsidiaries are no longer obliged with respect to such liabilities or are indemnified against
further liabilities; 
 (B)    any securities, notes or other obligations received by the Parent or any
such Restricted Subsidiary from such transferee that are converted by the Parent or such Restricted Subsidiary into cash or Cash Equivalents within 180 days following the closing of the Asset Sale, to the extent of the cash or Cash Equivalents
received in that conversion; 
 (C)    any Capital Stock or assets of the kind referred to in clauses
(b)(1)(B) or (D) below; 
 (D)    Indebtedness of any Restricted Subsidiary that is no longer a
Restricted Subsidiary as a result of such Asset Sale, to the extent that the Parent and each other Restricted Subsidiary are released from any guarantee of such Indebtedness in connection with such Asset Sale; 

(E)    consideration consisting of Indebtedness of the Parent or any Guarantor received from persons who
are not the Parent or any Restricted Subsidiary; 
 (F)    any consideration consisting of Equity
Interests in an entity (including a Non-Recourse Subsidiary) engaged in a Permitted Business received in connection with the sale or exchange of an Equity Interest in a Restricted Subsidiary so long as after
giving effect to such transaction, the entity in which the Equity Interest has been sold or exchanged remains a Restricted Subsidiary; and 

(G)    any Designated Non-cash Consideration received by the Parent
or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received

  
 68 

 
since the Issue Date pursuant to this clause (G) that is at that time outstanding, not to exceed the greater of (i) $75.0 million or (ii) 2.0% of Consolidated Total Assets, determined
at the time of receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being determined as of the
date of receipt thereof and without giving effect to subsequent changes in value). 
 (b)    within 365 days after the
receipt of any Net Proceeds from an Asset Sale, the Parent (or the applicable Restricted Subsidiary, as the case may be) may: 

(1)    apply an amount of cash equal to the amount of such Net Proceeds (at the option of the Parent or
Restricted Subsidiary): 
 (A)    to redeem Notes as described under Section 3.07, to purchase Notes
through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or to purchase Notes pursuant to an offer to all Holders at a purchase price equal to at least 100% of the principal amount thereof,
plus accrued and unpaid interest, if any, to (but not including) the date of purchase (a “Notes Offer”), which Notes Offer will constitute an application of Net Proceeds pursuant to this clause to the extent of the amount of the
Notes Offer, whether or not any Notes are tendered; 
 (B)    to acquire all or substantially all of the
assets of, or any Capital Stock of another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary (including a
Non-Recourse Subsidiary); 
 (C)    to make a capital
expenditure; 
 (D)    to acquire other assets (other than Capital Stock) not classified as current
assets under GAAP that are used or useful in a Permitted Business; 
 (E)    to repurchase, prepay,
redeem or repay (i) secured Indebtedness of the Parent or any of its Restricted Subsidiaries under Credit Facilities and (ii) Pari Passu Indebtedness; provided that in the case of clause (ii), a pro rata portion of such amount of
cash is applied to redeem Notes as described under Section 3.07, to purchase the Notes through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or to make a Notes Offer, which Notes Offer
will constitute an application of such amount of cash pursuant to this clause to the extent of the amount of the Notes Offer, whether or not any Notes are tendered; 

(F)    to repurchase, prepay, redeem or repay any Non-Recourse
Financing; or 
 (G)    any combination of the foregoing; or 

  
 69 

 (2)    enter into a binding commitment to apply the Net
Proceeds pursuant to clauses (b)(1)(B), (C) or (D) of this Section 4.10; provided that such binding commitment will be treated as a permitted application of the Net Proceeds from the date of such commitment until the earlier of:
(x) the date on which such acquisition or expenditure is consummated; and (y) the 180th day following the expiration of the aforementioned 365-day period. 

Pending the final application of any Net Proceeds, the Parent (or any applicable Restricted Subsidiary) may temporarily reduce revolving
credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 

(c)    Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) hereof will
constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, within ten Business Days thereof, the Issuer will make an Asset Sale Offer to all Holders (with a copy to the Trustee) and may
make an offer to all holders of other Pari Passu Indebtedness to purchase, prepay or redeem with the Excess Proceeds the maximum principal amount of Notes and such other Pari Passu Indebtedness (plus all accrued interest on the Indebtedness and the
amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price for the Notes in any Asset Sale Offer will be equal to 100% of the
principal amount, plus accrued and unpaid interest to, but excluding, the date of purchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date, and
will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and
other Pari Passu Indebtedness tendered into (or to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds or if the aggregate amount of the Notes tendered pursuant to a Notes Offer exceeds the amount
of the Excess Proceeds so applied, such Notes and such other Pari Passu Indebtedness, if applicable, will be purchased on a pro rata basis, based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be
deemed appropriate by the Issuer so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at
zero. An Asset Sale Offer may be made at the same time as consents are solicited with respect to an amendment, supplement or waiver of the Indenture, Notes and/or guarantees (but the Asset Sale Offer may not condition tenders on the delivery of such
consents). The Issuer may satisfy the foregoing obligation with respect to any Net Proceeds from an Asset Sale by making an offer to purchase Notes with respect to the amount of all or part of the available Net Proceeds prior to the expiration of
the application period referred to above with respect to the amount of all or a part of the available Net Proceeds in advance of being required to do so by this Section 4.10(c) and all references in this Section 4.10(c) or
Section 3.09 to the Asset Sale Offer and procedures with respect thereto shall apply equally to such advance portion of such advance offer. 

(d)    The Issuer will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any
securities laws or regulations conflict with the 

  
 70 

 
provisions of Section 3.09 hereof or this Section 4.10, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under Section 3.09 hereof or this Section 4.10 by virtue of such compliance. 

Section 4.11    Limitation on Transactions with Affiliates. 

(a)    The Parent will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into or suffer
to exist any transaction or series of related transactions (including, without limitation, the sale, purchase, exchange or lease of assets or property or the rendering of any service) with, or for the benefit of, any Affiliate of the Parent or any
Restricted Subsidiary involving aggregate payments or consideration in excess of $5.0 million, unless: 

(1)    such transaction or series of transactions is on terms that, taken as a whole, are not materially
less favorable to the Parent or such Restricted Subsidiary, as the case may be, than those that would have been obtained in a comparable transaction at such time on an arm’s-length basis with third
parties that are not Affiliates; and 
 (2)    with respect to any transaction or series of related
transactions involving aggregate payments or the transfer of assets or the provision of services, in each case having a value greater than $75.0 million, the Board of Directors of the Parent must approve such transaction. 

(b)    Notwithstanding the foregoing, the restrictions set forth in this Section 4.11 will not apply to: 

(1)    customary directors’ fees and expenses, indemnities and similar arrangements (including the
payment of directors’ and officers’ insurance premiums), consulting fees, employee compensation, employee and director bonuses, employment agreements and arrangements or employee benefit arrangements, including, without limitation, stock
options, stock awards, stock appreciation rights, performance awards, cash awards, legal fees or other benefits awarded under any employee incentive or similar compensation plan, as determined in good faith by Parent’s Board of Directors or
senior management; 
 (2)    any Restricted Payment that does not violate Section 4.07 or any
Permitted Investment; 
 (3)    loans and advances (or guarantees to third party loans) to directors,
officers or employees of the Parent or any Restricted Subsidiary made in the ordinary course of business; 

(4)    agreements and arrangements existing on the Issue Date, and the performance by the Parent or any
Restricted Subsidiary of their obligations thereunder and any amendments, modifications, replacements or supplements thereto; provided that any such amendments, modifications, replacements or supplements, taken as a whole, are not more
disadvantageous to the Holders in any material respect than the original agreements or arrangements as in effect on the Issue Date as determined by Parent’s Board of Directors or senior management; 

  
 71 

 (5)    the issuance of securities pursuant to, or for
the purpose of the funding of, employment benefit arrangements, including, without limitation, stock options, stock awards, stock appreciation rights, performance awards, cash awards, legal fees or other benefits awarded under any employee incentive
or similar compensation plan, as long as the terms thereof are or have been previously approved by the Parent’s or the relevant Restricted Subsidiary’s Board of Directors; 

(6)    transactions between or among the Parent and the Restricted Subsidiaries or between or among
Restricted Subsidiaries; 
 (7)    any transaction between or among: (i) the Parent and/or its
Restricted Subsidiaries and (ii) any Joint Venture (where such Joint Venture is an Affiliate solely because the Parent and/or its Restricted Subsidiaries owns an equity interest in or otherwise controls such Joint Venture): (A) pursuant to the
terms of the respective Joint Venture or other agreements, including but not limited to engineering, procurement and construction contracts, operation and maintenance contracts and other project agreements; (B) in the ordinary course of
business in accordance with past practice; (C) pursuant to cash pooling or other similar arrangements; (D) consisting of an Investment; (E) which are fair to the Parent or the relevant Restricted Subsidiary, in the reasonable
determination of Parent’s Board of Directors or senior management; or (F) which is on terms no less favorable than those that could reasonably have been obtained at such time from an unaffiliated Person, in the reasonable determination of
Parent’s Board of Directors or senior management; 
 (8)    any issuance of Equity Interests (other
than Disqualified Stock) of the Parent; 
 (9)    the existence of, or the performance by the Parent or
any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement relating thereto) to which it is a party as of the Issue Date and any similar
agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Parent or any of its Restricted Subsidiaries of, 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 (9) to the extent that the terms of any such amendment or new agreement, taken as a whole, are not disadvantageous to the Holders in any
material respect; 
 (10)    transactions with respect to which the Parent has obtained an opinion as to
the fairness to Parent and its Restricted Subsidiaries from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing; 

(11)    transactions with (i) Unrestricted Subsidiaries or (ii) Joint Ventures in which the
Parent or a Subsidiary of the Parent holds or acquires an ownership interest (whether by way of Capital Stock or otherwise), in each case so long as the terms of such transactions are, taken as a whole, at least as favorable to the Parent or the
applicable Restricted Subsidiary as might reasonably have been obtained at such time from an unaffiliated party as determined by Parent’s Board of Directors or senior management; 

  
 72 

 (12)    transactions between the Parent or any of its
Restricted Subsidiaries and any Person that is an Affiliate solely as a result of the ownership by the Parent or any of the Restricted Subsidiaries of Capital Stock of such Person; 

(13)    transactions with Persons solely in their capacity as holders of Indebtedness of the Parent or any
of its Restricted Subsidiaries where such Persons are treated no more favorably than holders of Indebtedness of the Parent or such Restricted Subsidiaries generally; 

(14)    Permitted Project Undertakings and Permitted Equity Commitments; and 

(15)    (i) pledges and other transfers of Equity Interests in Unrestricted Subsidiaries and (ii) any
transactions with an Affiliate in which the consideration paid consists solely of Equity Interests of the Parent. 

Section 4.12    Limitation on Liens. 

The Parent will not, and will not permit any of its Restricted Subsidiaries to create, any Lien upon the whole or any part of the currently
owned or after-acquired property of the Parent or any of its Restricted Subsidiaries or assets to secure any Indebtedness (other than Permitted Liens) unless in any such case, before or at the same time as the creation of the Lien, all amounts
payable under the Notes are secured equally and ratably with such Indebtedness (until such time as such Indebtedness is no longer secured by such Lien). Any such Lien shall provide that it shall be released automatically upon repayment of the
related Indebtedness. 
 Section 4.13    Maintenance of Cash Asset Coverage Ratio. 

The Parent will maintain a Cash Asset Coverage Ratio of not less than 2.0 to 1.0 as of the last day of each fiscal quarter ending after the
Issue Date. 
 Section 4.14    Existence. 

Except as would not be prohibited under Article 5 and Section 10.04 hereof, the Issuer and each of the Guarantors shall do or cause to be
done all things necessary to preserve and keep in full force and effect its corporate, limited liability company, partnership or other existence, as applicable. 

Section 4.15    Offer to Repurchase Upon Change of Control Triggering Event. 

(a)    Upon the occurrence of a Change of Control Triggering Event, the Issuer will be required to make an offer (a
“Change of Control Offer”) to each Holder to repurchase all or any part (being not less than $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to the terms set forth in this Indenture.

 (b)    In the Change of Control Offer, the Issuer will offer a payment in cash equal to 101% of the aggregate
principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”), subject to the rights of Holders on the relevant
record date to receive interest due on 

  
 73 

 
the relevant Interest Payment Date. Within 30 days following any Change of Control, the Issuer will deliver notice to each Holder (with a copy to the Trustee) stating that a Change of Control
Offer is being made and offering to repurchase Notes on the date (the “Change of Control Payment Date”) specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is
given, pursuant to the procedures required by this Indenture and described in such notice. The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities
laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict
with this Section 4.15, the Issuer will comply with any applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of such compliance. 

(c)    On the Change of Control Payment Date, the Issuer will, to the extent lawful: 

(1)    accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of
Control Offer; 
 (2)    deposit with the Paying Agent an amount equal to the Change of Control Payment
in respect of all Notes or portions of Notes properly tendered; and 
 (3)    deliver or cause to be
delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. 

The Paying Agent will promptly cause to be delivered to each Holder properly tendered the Change of Control Payment for such Notes, and the
Trustee (or its authenticating agent) will, upon receipt of an Authentication Order, promptly authenticate and deliver (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the
Notes surrendered, if any. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

(d)    The provisions described above that require the Issuer to make a Change of Control Offer following a Change of
Control Triggering Event will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control Triggering Event, this Indenture does not contain provisions that permit
the Holders to require that the Issuer repurchase or redeem the respective Notes in the event of a takeover, recapitalization or similar transaction. 

(e)    The Issuer will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if:
(1) 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 this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes
properly tendered and not withdrawn under the Change of Control Offer; or (2) a notice of redemption has been given pursuant to this Indenture as described under Section 3.07, unless and until there is a default in payment of the
applicable redemption price. Notwithstanding anything to the contrary 

  
 74 

 
contained herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon the consummation of such Change of Control, if a definitive agreement
is in place for the Change of Control at the time the Change of Control Offer is made. 

Section 4.16    Additional Note Guarantees. 

If (a) the Parent forms or acquires a Domestic Subsidiary (other than an Excluded Subsidiary) after the Issue Date, (b) any Domestic
Subsidiary that is an Excluded Subsidiary on the Issue Date thereafter ceases to be an Excluded Subsidiary or (c) any Domestic Subsidiary of the Parent guarantees any obligations with respect to any other Material Indebtedness of the Issuer,
then, in each case, such Domestic Subsidiary will become a Guarantor of the Notes and execute a supplemental indenture within 30 days of the date of its formation, acquisition or cessation of being an Excluded Subsidiary or the date on which it
guaranteed such Material Indebtedness of the Issuer, as the case may be. The form of such supplemental indenture is attached as Exhibit E hereto. 

Section 4.17    Designation of Restricted and Unrestricted Subsidiaries. 

The Board of Directors of Parent may designate any Subsidiary of the Parent, other than the Issuer (including any newly acquired or newly
formed Subsidiary or a Person becoming a Subsidiary through merger, consolidation or other business combination transaction, or Investment therein), to be an Unrestricted Subsidiary in accordance with the definition of “Unrestricted
Subsidiary” and only if: 
 (1)    such Subsidiary or any of its Subsidiaries does not own any
Equity Interests or Indebtedness of, or own or hold any Lien on any property of, the Parent or any other Subsidiary of the Parent which is not a Subsidiary of the Subsidiary to be so designated or otherwise an Unrestricted Subsidiary; and 

(2)    such designation and the Investment of the Parent or any of the Restricted Subsidiaries in such
Subsidiary complies with Section 4.07. Any such designation by the Board of Directors of Parent shall be evidenced to the Trustee by delivering to the Trustee a copy of the resolution of the Board of Directors of Parent giving effect to such
designation and an Officer’s Certificate certifying that such designation complies with the foregoing conditions. 
 If, at any time,
any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed
to be incurred by a Restricted Subsidiary of the Parent as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Parent will be in default of such covenant. The Board of Directors
of Parent may designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that immediately after giving effect to such designation (1) no Default or Event of Default would result therefrom and (2) the Parent could
incur at least $1.00 of additional Indebtedness under Section 4.09(a) on a pro forma basis taking into account such designation. Any such designation by the Board of Directors of Parent shall be evidenced to the Trustee by promptly delivering
to the Trustee a copy of the resolution of the Board of Directors giving effect to such designation and an Officer’s Certificate certifying that such designation complied with the foregoing provisions.

 Section 4.18    Covenant Fall Away. 

If (i) a Rating Release Event has occurred and (ii) no Default or Event of Default has occurred and is continuing, then, beginning on
that day, the Parent and its Restricted Subsidiaries shall be released from their respective obligations under the provisions of this Indenture described in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.16 and the provisions of clause
(4) of the first paragraph of Section 5.01 and such provisions shall be terminated and permanently cease to have effect. In addition, after the conditions to termination of such covenants have been satisfied, the Parent may not designate
any of its Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.17 and the definition of “Unrestricted Subsidiary.” The Issuer shall promptly give notice to the Trustee and provide the Trustee with an Officer’s
Certificate stating that the conditions set forth in this Section 4.18 have been satisfied; provided that such notification shall not be a condition for the termination of the covenants described under this Section 4.18 to be
effective. The Trustee shall be under no obligation to monitor the ratings of the Notes, determine, or verify the Issuer’s determination of, the satisfaction of the conditions set forth in this Section 4.18 or inform Holders of any of the
foregoing.

 Section 6.02    Acceleration. 

In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof with respect to the Parent or the Issuer,
all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the then outstanding
Notes by written notice to the Issuer (with a copy to the Trustee if given by the Holders) may declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Parent and the Trustee may, on
behalf of all of the Holders of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if all existing Events of Default
(except nonpayment of principal of, premium on, if any, or interest, if any, on the Notes that has become due solely because of the declaration of acceleration) have been cured or waived. 

In the event of a declaration of acceleration of the Notes because an Event of Default described in clause (5) of Section 6.01 has
occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the Payment Default or other default triggering such Event of Default pursuant to such clause (5) of Section 6.01 shall be remedied
or cured, or waived by the holders of the Indebtedness with respect to which a Payment Default has occurred within 30 days after the declaration of acceleration of the Notes; provided that (1) the annulment of the acceleration of the
Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium on, if any, or interest, if any, on the Notes that became due solely
because of the acceleration of the notes, have been cured or waived. 
 If a Default occurs for a failure to report or deliver a required
certificate in connection with another default (an “Initial Default”) then at the time such Initial Default is cured, such Default for a failure to report or deliver a required certificate in connection with the Initial Default will
also be cured without any further action and any Default or Event of Default for the failure to comply with the time periods prescribed in Section 4.03 or otherwise to deliver any notice or certificate pursuant to any other provision of this
Indenture shall be deemed to be cured upon the delivery of any such report required by such covenant or notice or certificate, as applicable, even though such delivery is not within the prescribed period specified in this Indenture. 

Section 6.03    Other Remedies. 

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium
on, if any, or interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee
may maintain a proceeding even if it does not possess any of the Notes 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. All remedies are cumulative to the extent permitted by law. 

  
 80 

 Section 6.04    Waiver of Past Defaults. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the
Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the Notes
(including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related
payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver
shall extend to any subsequent or other Default or impair any right consequent thereon. 

Section 6.05    Control by Majority. 

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be
unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability (it being understood that the Trustee does not have an affirmative duty to determine if any action is prejudicial to any Holder). The
Trustee may withhold from Holders notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest. 

Section 6.06    Limitation on Suits. 

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 unless: 
 (1)    such Holder has previously given the Trustee written notice
that an Event of Default is continuing; 
 (2)    Holders of at least 30% in aggregate principal amount
of the then outstanding Notes make a written request to the Trustee to pursue the remedy; 
 (3)    such
Holder or Holders offer and, if requested, provide to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; 

(4)    the Trustee has not complies with such request within 60 days after receipt of the request and the
offer or provision of security or indemnity; and 

  
 81 

 (5)    during such
60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 

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 Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium on, if any, or
interest, if any, on the Note, on or after the respective due dates expressed in the Note, 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(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover
judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium on, if any, and interest, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

Section 6.09    Trustee May File Proofs of Claim. 

The Trustee is authorized to 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 the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor
upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such 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 to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out
of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

  
 82 

 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, its agents and attorneys for amounts due under Section 7.06 hereof, including payment of all
compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, if any,
ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, if any, respectively; and 

Third: to the Issuer or to such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 

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 a 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, 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any
Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest within the meaning of the TIA, it must eliminate such conflict within 90 days or resign. Any
Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.09 hereof. 

Section 7.04    Trustee’s Disclaimer. 

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not
be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other
than its certificate of authentication. 
 Section 7.05    Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if it is known to a Responsible Officer of the Trustee, the Trustee will mail
(or, in the case of Global Notes, transmit in accordance 

  
 86 

 
with the procedures of the Depositary) to Holders of Notes a notice of the Default or Event of Default within the later of 90 days after it occurs or promptly after obtaining knowledge thereof.
Except in the case of a Default or Event of Default in payment of principal of, premium on, if any, interest, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders. 
 Section 7.06    Compensation and
Indemnity. 
 (a)    The Issuer will pay to the Trustee from time to time compensation for its acceptance of this
Indenture and services hereunder as agreed between the Issuer and the Trustee. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuer will reimburse the Trustee promptly upon
request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents
and counsel. 
 (b)    The Issuer and the Guarantors will, jointly and severally, indemnify the Trustee against any and
all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer and the
Guarantors (including this Section 7.06) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or
duties hereunder, except to the extent any such loss, liability or expense may be attributable to the Trustee’s own gross negligence or willful misconduct. The Trustee will notify the Issuer promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Issuer will not relieve the Issuer or any of the Guarantors of their obligations hereunder. The Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The
Trustee may have separate counsel and the Issuer will pay the reasonable fees and expenses of such counsel. Neither the Issuer nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

 (c)    The obligations of the Issuer and the Guarantors under this Section 7.06 will survive the satisfaction
and discharge of this Indenture and the resignation or removal of the Trustee. 
 (d)    To secure the Issuer’s and
the Guarantors’ payment obligations in this Section 7.06, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium on, if any,
interest, if any, on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture. 

(e)    When the Trustee incurs expenses or renders services after an Event of Default specified in clause (8) or (9)
of Section 6.01 hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 

  
 87 

 Section 7.07    Replacement of Trustee. 

(a)    A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the
successor Trustee’s acceptance of appointment as provided in this Section 7.07. 
 (b)    The Trustee may
resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and
the Issuer in writing. The Issuer may remove the Trustee if: 
 (1)    the Trustee fails to comply with
Section 7.09 hereof; 
 (2)    the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law; 
 (3)    a custodian or public
officer takes charge of the Trustee or its property; or 
 (4)    the Trustee becomes incapable of
acting. 
 (c)    If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason,
the Issuer will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the
successor Trustee appointed by the Issuer. 
 (d)    If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee. 
 (e)    If the Trustee, after written request by any Holder who has been a Holder for at least six
months, fails to comply with Section 7.09 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(f)    A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer.
Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its
succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in
Section 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Issuer’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee. 

  
 88 

 Section 7.08    Successor Trustee by Merger,
etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to,
another corporation, the successor corporation without any further act will be the successor Trustee. 

Section 7.09    Eligibility; Disqualification. 

There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trust powers, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least
$100.0 million as set forth in its most recent published annual report of condition. 
 ARTICLE 8 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

Section 8.01    Option to Effect Legal Defeasance or Covenant Defeasance. 

The Issuer may, at the option of its Board of Directors evidenced by a resolution set forth in an Officer’s Certificate, at any time,
elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 

Section 8.02    Legal Defeasance and Discharge. 

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and each of the
Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the
conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented
by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and
(2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute such instruments reasonably requested by the Issuer
acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 

(1)    the rights of Holders of outstanding Notes to receive payments in respect of the principal of,
premium on, if any, or interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 

(2)    the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02
hereof; 
 (3)    the rights, powers, trusts, duties, indemnities and immunities of the Trustee hereunder
and the Issuer’s and the Guarantors’ obligations in connection therewith; and 

  
 89 

 (4)    this Article 8. 

Subject to compliance with this Article 8, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise
of its option under Section 8.03 hereof. 
 Section 8.03    Covenant Defeasance. 

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and each of the
Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 3.09, 4.03, 4.04, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,
4.13, 4.15, 4.16 and 4.17 and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants,
but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to
the outstanding Notes and Note Guarantees, the Issuer and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of
any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), (4), (5), (6), and (7) hereof will not constitute Events of Default. 

Section 8.04    Conditions to Legal or Covenant Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 

(1)    the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash
in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of
independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuer must specify whether the Notes are
being defeased to such Stated Maturity or to a particular redemption date (provided that if such redemption is made as provided under Section 3.07(c) (x) the amount of cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Redemption Premium calculated as of the date of such deposit and
(y) the depositor must irrevocably deposit or cause to be deposited additional money (a “Shortfall”) in trust on the redemption date as necessary to pay the Applicable Redemption

  
 90 

 
Premium as determined on such date) (it being understood that any Legal Defeasance or Covenant Defeasance shall be subject to the condition subsequent that such Shortfall is in fact paid);
provided, however, that the Trustee shall have no liability whatsoever in the event that such Shortfall is not in fact paid after any Legal Defeasance or Covenant Defeasance. Any Shortfall will be set forth in an Officer’s Certificate delivered
to the Trustee at least two Business Days prior to the deposit of such Shortfall that confirms that such Shortfall will be applied toward such redemption); 

(2)    in the case of an election under Section 8.02 hereof, the Issuer shall deliver to the Trustee
an Opinion of Counsel confirming that: 
 (A)    the Issuer has received from, or there has been
published by, the Internal Revenue Service a ruling; or 
 (B)    since the Issue Date, 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 of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred; 
 (3)    in the
case of an election under Section 8.03 hereof, the Issuer shall deliver to the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a
result of such Covenant 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 Covenant Defeasance had not occurred; 

(4)    no Default or Event of Default shall have occurred and is continuing on the date of such deposit
(other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings); 

(5)    such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or
constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Parent or any of its Subsidiaries is a party or by
which the Parent or any of its Subsidiaries is bound; 
 (6)    the Issuer must deliver to the Trustee an
Officer’s Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders of Notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of
the Issuer or others; and 

  
 91 

 (7)    the Issuer must deliver to the Trustee an
Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 

Section 8.05    Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

 Subject to Section 8.06 hereof, all money and non-callable Government Securities (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held
in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such money need not be segregated from other funds except to the extent required by law. 

The Issuer will pay and indemnify the Trustee against any Tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such Tax, fee or other charge which by law is for the
account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or
pay to the Issuer from time to time upon the request of the Issuer any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

Section 8.06    Repayment to Issuer. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium on,
if any, or interest, if any, on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) will be
discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the
Issuer as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of
such money then remaining will be repaid to the Issuer. 

  
 92 

 Section 8.07    Reinstatement. 

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government
Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or Governmental Authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s
and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium on, if any, interest, if any, on, any
Note following the reinstatement of its obligations, the Issuer will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE 9 
 AMENDMENT,
SUPPLEMENT AND WAIVER 
 Section 9.01    Without Consent of Holders of Notes. 

Notwithstanding Section 9.02 of this Indenture, without the consent of any Holder, the Issuer, the Guarantors and the Trustee may amend or
supplement this Indenture, the Notes or the Note Guarantees: 
 (1)    to cure any ambiguity, mistake,
defect or inconsistency; 
 (2)    to provide for uncertificated Notes in addition to or in place of
certificated Notes; 
 (3)    to provide for the assumption of the Parent’s, the Issuer’s or
any Subsidiary Guarantor’s obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Parent’s, the Issuer’s or such Subsidiary Guarantor’s assets; 

(4)    to make any change that would provide any additional rights or benefits to the Holders or that does
not adversely affect the legal rights hereunder of any Holder in any material respect; 
 (5)    to
comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 

(6)    to conform the text of this Indenture or the Notes to any provision of the “Description of the
Notes” section of the Issuer’s Offering Memorandum dated August 10, 2021, relating to the offering of the Initial Notes, as evidenced by an Officer’s Certificate to that effect; 

(7)    to evidence and provide for the acceptance and appointment under this Indenture of a successor
Trustee pursuant to the requirements thereof; 

  
 93 

 (8)    to provide for or confirm the issuance of
Additional Notes in accordance with this Indenture; or 
 (9)    to provide for any Note Guarantee or to
effect the release of a Guarantor from any its obligations under its Note Guarantee or this Indenture to the extent permitted hereby. 

Upon the request of the Issuer, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join
with the Issuer and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but
the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

Section 9.02    With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture
(including, without limitation, Section 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without
limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof,
any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium on, if any, or interest, if any, on, the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation,
Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are
considered to be “outstanding” for purposes of this Section 9.02. 
 Upon the request of the Issuer accompanied by a
resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon
receipt by the Trustee of the documents described in Sections 7.02 and 9.05 hereof, the Trustee will join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental
indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed
amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or
waiver under this Section 9.02 becomes effective, the Issuer will mail (or, in the case of Global Notes, transmit in accordance with the procedures of the 

  
 94 

 
Depositary) to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail or transmit such notice, or any defect
therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then
outstanding voting as a single class may waive compliance in a particular instance by the Issuer or any Guarantor with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an
amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 

(1)    reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or
waiver; 
 (2)    reduce the principal of or change the fixed maturity of any Note or alter or waive any
of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof and provisions relating to the number of days of notice to be given in the event of a redemption); 

(3)    reduce the rate of or change the time for payment of interest on any Note; 

(4)    waive a Default or Event of Default in the payment of principal of, premium on, if any, or interest,
if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); 

(5)    make any Note payable in currency other than that stated in the Notes; 

(6)    make any change in the provisions of this Indenture relating to waivers of past Defaults or the
rights of Holders of Notes to receive payments of principal of, premium, if any, on, or interest, if any, on the Notes; 

(7)    waive a redemption payment with respect to any Note (other than a payment required by
Sections 3.09, 4.10 or 4.15 hereof); 
 (8)    release any Guarantor from any of its obligations
under its Note Guarantee or this Indenture other than in accordance with the terms of this Indenture; or 

(9)    make any change in the preceding amendment and waiver provisions. 

Section 9.03    Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to
its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

  
 95 

 Section 9.04    Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in
exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

 Section 9.05    Trustee to Sign Amendments, etc. 

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Board of Directors of the Issuer approves it. In executing any amended or supplemental indenture,
the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.02 hereof, an Officer’s Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
 ARTICLE 10 

NOTE GUARANTEES 

Section 10.01    Note Guarantee. 

(a)    Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each
Holder authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: 

(1)    the principal of, premium, if any, on, and interest, if any, on the Notes will be promptly paid in
full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, interest, if any, on, the Notes, if lawful, and all other obligations of the Issuer to the Holders or the
Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

(2)    in case of any extension of time of payment or renewal of any Notes or any of such other
obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and
severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

  
 96 

 (b)    The Guarantors hereby agree that their obligations hereunder are
unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the
recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Note Guarantee
will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 

(c)    If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any
custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full
force and effect. 
 (d)    Each Guarantor agrees that it will not be entitled to any right of subrogation in relation
to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other
hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in
respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable
by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights
of the Holders under the Note Guarantee. 
 Section 10.02    Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to
any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such
maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

 Section 10.03    Execution and Delivery of Note Guarantee.

 To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture or, if applicable,
a Supplemental Indenture in the form of Exhibit E, shall be executed on behalf of such Guarantor by an Officer of such Guarantor. 

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
 If an Officer whose signature is on this Indenture
no longer holds that office at the time the Trustee authenticates the Note, the Note Guarantee will be valid nevertheless. 
 The delivery
of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors.

The Parent Guarantee will be released automatically: 

(a)    upon repayment in full of the Notes;

Guarantor (including by way of merger, consolidation, dividend, amalgamation, distribution or otherwise) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary of the Issuer; 

(b)    in connection with any sale or other disposition of Capital Stock of that Subsidiary Guarantor to a Person that is

(g)    upon such Subsidiary Guarantor (i) becoming an Immaterial Subsidiary or (ii) to the extent such
Subsidiary Guarantor became a Guarantor solely pursuant to Section 4.16(c), upon the release of such Subsidiary Guarantor’s guarantee of all obligations with respect to all other Material Indebtedness of the Issuer at that time outstanding
in accordance with the terms thereof. 
 ARTICLE 11 

SATISFACTION AND DISCHARGE 

Section 11.01    Satisfaction and Discharge. 

This Indenture will be discharged and will cease to be of further effect (except as to surviving rights of registration of transfer or exchange
of the Notes and as otherwise specified in this Article 11), as to all Notes issued hereunder, when: 

(1)    either: 

(a)    all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been
replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or 

(b)    all Notes that have not been delivered to the Trustee for cancellation have become due and payable
or will become due and payable within one year by reason of the mailing or transmitting of a notice of redemption or otherwise and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in
trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment
of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and interest, if any, to, but excluding, the date of maturity or redemption (provided that if such
redemption is made as provided under Section 3.07(c), (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be
determined using an assumed Applicable Redemption Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited the Shortfall in trust on the redemption date as necessary to pay the
Applicable Redemption Premium as determined by such date) (it being understood that any satisfaction and discharge shall be subject to the condition subsequent that such Shortfall is in fact paid); provided, however, that the Trustee shall have no
liability whatsoever in the event that such Shortfall is not in fact paid after any satisfaction and discharge of this Indenture. Any Shortfall will be set forth in an Officer’s Certificate delivered to the Trustee at least two Business Days
prior to the deposit of such Shortfall that confirms that such Shortfall will be applied toward such redemption); 

  
 99 

 (2)    in respect of subclause (b) of clause
(1) of this Section 11.01, no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any
similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or
any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent
deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings); 

(3)    the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this
Indenture; and 
 (4)    the Issuer has delivered irrevocable written instructions to the Trustee under
this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 In addition, the
Issuer must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 

Notwithstanding the satisfaction and discharge of this Indenture, the provisions of Section 7.06 hereof and, if money has been deposited
with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof, will survive. 

Section 11.02    Application of Trust Money. 

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held
in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal, premium, if any, interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof 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 Issuer’s and any Guarantor’s obligations under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium on, if any, or interest, if any, on, any Notes because of
the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below
unless otherwise indicated. 
 (1)    INTEREST. Sunnova Energy
Corporation, a Delaware corporation (the “Issuer”), promises to pay or cause to be paid interest on the unpaid principal amount of this Note at 5.875% per annum. The Issuer will pay interest, if any, semi-annually in arrears on
March 1 and September 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”) (and no interest shall accrue on such payment as the result of such
delay), [provided that the first Interest Payment Date shall be March 1, 2022.] Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance;
provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months. 

(2)    METHOD OF PAYMENT. The Issuer
will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered Holders at the close of business on the February 15 or August 15 next preceding the Interest Payment Date, even if such Notes are
canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if
any, at the office or agency of the Paying Agent and Registrar, or, at the option of the Issuer, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that
payment by wire transfer of immediately available funds will be required with respect to principal of, premium on, if any, and interest, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer
instructions to the Issuer or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3)    PAYING AGENT AND
REGISTRAR. Initially, Wilmington Trust, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the
Holders. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar. 

(4)    INDENTURE. The Issuer issued the Notes under an Indenture,
dated as of August 17, 2021 (the “Indenture”), among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the
Indenture for a statement of such terms. To the extent 

  
 A-3 

 
any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the
Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. 

(5)    OPTIONAL REDEMPTION. The Notes shall be redeemable at the
option of the Issuer as provided in Section 3.07 of the Indenture. 

(6)    MANDATORY REDEMPTION. The Issuer is not required

$1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of
purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date (the “Change of Control Payment”). Within thirty days following any Change of Control, the
Issuer will mail (or, in the case of Global Notes, transmit with the procedures of the Depositary) a notice (with a copy to the Trustee) to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

 (b)    If the Issuer or a Restricted Subsidiary of the Issuer consummates an Asset Sale, the Issuer
may in circumstances provided in the Indenture be required to make an Asset Sale Offer to all Holders (with a copy to the Trustee) and holders of certain other Pari Passu Indebtedness to purchase Notes or such other Pari Passu Indebtedness using
Excess Proceeds. Holders of Notes that are the subject of an Asset Sale Offer from the Issuer may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes. 

(8)    NOTICE OF REDEMPTION. At least 10
days but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed, by first class mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary), a notice of redemption to each
Holder (with a copy to the Trustee) whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed or transmitted more than 60 days prior to a redemption date if the notice is issued in connection with a
defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Articles 8 or 11 thereof. 
 Any
such redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent as set forth in the Indenture. 

  
 A-4 

 (9)    DENOMINATIONS,
TRANSFER EXCHANGE. The Notes are in registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange
or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the next succeeding Interest Payment Date. 

(10)    PERSONS DEEMED OWNERS. The
registered Holder may be treated as the owner of it for all purposes under the Indenture. 

(11)    AMENDMENT, SUPPLEMENT AND
WAIVER. Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then
outstanding Notes including Additional Notes, if any, voting as a single class, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the
Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class. Without the consent of any Holder, the Indenture, the Notes or the Note Guarantees may be amended or
supplemented for certain purposes specified in the Indenture. 
 (12)    DEFAULTS
AND REMEDIES. In the case of an Event of Default, the Notes will be subject to the remedies provided for in Article 6 of the Indenture. 

(13)    TRUSTEE DEALINGS WITH
ISSUER. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates,
as if it were not the Trustee. 
 (14)    NO RECOURSE
AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, will have any liability for any obligations of the Issuer or the Guarantors under
the Notes, the Indenture, the Note Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of
the consideration for issuance of the Notes.

authenticated by the manual signature of the Trustee or an authenticating agent.

Act).

NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other
identification numbers placed thereon.

NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE AND THE NOTE GUARANTEES.

SUBSCRIPTION AGREEMENT

 

Subscription
Agreement between OriginClear, Inc., a Nevada corporation with its principal place of business at 13575
58th Street N, Suite 200, Clearwater, Florida 33760 (the “Company”), and the purchaser
identified on the signature page to this Agreement (the “Subscriber”), and is being delivered to the Subscriber in
connection with the purchaser’s investment in the Company. The Company is conducting a private placement (the “Offering”)
for a single investment amount of $250,000 entitling the Subscriber to (i) 25 (twenty-five) shares (the “Series X Preferred Shares”)
of the Company’s newly created convertible Series X Preferred Stock having the rights set forth in the Certificate of Designation
of Series X Preferred Stock substantially in the form of Annex B hereto (the “Series X Certificate of Designation”),
and (ii) such number of shares of the Company’s common stock as equals $125,000 divided by the per share fair market value of the
Company’s common shares as of the date of the Subscriber’s acceptance of this Subscription Agreement (the “Added
Common Shares”) (the Series X Preferred Shares and the Added Common Shares are referred to collectively herein as the “Securities”)
at a purchase price of $250,000. As set forth in the Series X Certificate of Designation, the Series X Preferred Shares are subject to
a cash redemption option exercisable by the Subscriber any time following the first anniversary of this Subscription Agreement until the
second anniversary of this Subscription Agreement, to cause the Company to redeem all of the Series X Preferred Shares purchased by the
Subscriber at a price equal to 125% of the $250,000 original purchase price, or $312,500, without affecting the Subscriber’s ownership
of the Added Common Shares. The Series X Preferred Shares are also subject to the Subscriber’s option, exercisable at any time,
to cause the Company to redeem all of the Subscribers purchased Series X Preferred Shares in exchange for the issuance to the Subscriber
of that number of the Company’s common shares as shall equal 250% of the original $250,000 purchase price, or $625,000, divided
by the fair market value of the Company’s common shares as of the date the Subscriber executed this Subscription Agreement.

Solely by way
of illustration, in the event a Subscriber hereunder purchases the Securities for an investment of $250,000, and the per share fair
market value of the Company’s common stock as of the Subscribers execution of this Securities Purchase Agreement was $0.20 per common
share, such Subscriber would receive 25 shares of Series X Preferred Stock and 625,000 Added Common Shares.

 

The net proceeds
of this offering, after the payment of offering-related expenses, will be used to fund the operations of the Company.

 

The Offering hereunder
will terminate on the earlier of (i) August 5, 2022, or (ii) the sale of $250,000 of the Securities, subject however, to the right of
the Company to terminate or extend this Offering at any time in its discretion and the Company’s right to reject any subscription
in whole or in part.

any reason or for no reason, notwithstanding the Subscriber’s prior receipt of notice of acceptance of the Subscriber’s subscription.
In the event the Closing does not take place for any reason or no reason (including, without limitation, because the Company has terminated
the Offering, which the Company may do at any time in its discretion), this Agreement and any other Transaction Documents shall thereafter
be terminated and have no force or effect, and the parties shall take all steps, to ensure that the Aggregate Purchase Price shall promptly

3. THE
SUBSCRIBER’S REPRESENTATIONS, WARRANTIES AND COVENANTS

 

The Subscriber
hereby acknowledges, agrees with and represents, warrants and covenants to the Company, as follows:

 

(a) The
Subscriber has full power and authority to enter into this Agreement, the execution and delivery of which has been duly authorized by
all the necessary corporate actions, and no other acts or proceedings on the part of the Subscriber are necessary to authorize the execution,
delivery or performance by the Subscriber of this Agreement, if applicable, and this Agreement constitutes a valid and legally binding
obligation of the Subscriber, except as may be limited by bankruptcy, reorganization, insolvency, moratorium and similar laws of general
application relating to or affecting the enforcement of rights of creditors, and except as enforceability of the obligations hereunder
are subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or law).

 

(b) The
Subscriber acknowledges its understanding that the Offering and sale of the Securities is intended to be exempt from registration under
the Securities Act of 1933, as amended (the “Securities Act”), by virtue of Section 4(a)(2) of the Securities Act and
the provisions of Regulation D promulgated thereunder (“Regulation D”). In furtherance thereof, the Subscriber represents
and warrants to the Company and its affiliates as follows:

 

(i) The
Subscriber realizes that the basis for the exemption from registration may not be available if, notwithstanding the Subscriber’s
representations contained herein, the Subscriber is merely acquiring the Securities for a fixed or determinable period in the future,
or for a market rise, or for sale if the market does not rise. The Subscriber does not have any such intention.

 

(ii) The
Subscriber realizes that the basis for exemption would not be available if the Offering is part of a plan or scheme to evade registration
provisions of the Securities Act or any applicable state or federal securities laws.

 

(iii) The
Subscriber is acquiring the Securities solely for investment purposes, and not with a view towards, or resale in connection with, any
distribution of the Securities

 

(iv) The
Subscriber has the financial ability to bear the economic risk of the Subscriber’s investment, has adequate means for providing
for its current needs and contingencies, and has no need for liquidity with respect to an investment in the Company.

 

(v) The
Subscriber and the Subscriber’s attorney, accountant, purchaser representative and/or tax advisor, if any (collectively, the “Advisors”)
has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of a prospective
investment in the Securities. If other than an individual, the Subscriber also represents it has not been organized solely for the purpose
of acquiring the Securities.

 

    5

     

    

 

(vi) The
Subscriber has carefully reviewed and understands this Agreement in its entirety, including without limitation all Exhibits hereto (including
the Series X Certificate of Designation, included as Annex B) and including the Risk Factors set forth in Annex C. Without limiting the
generality of the foregoing, the Subscriber is aware that, pursuant to the Series X Certificate of Designation, upon conversion of shares
of Series X Preferred Stock, a Subscriber that holds securities of the Company that such Subscriber purchased in certain prior offerings
of the Company will be entitled to Make-Good Shares (as defined therein), subject to the terms and conditions set forth therein, that
a Subscriber that does not hold such securities purchased in such prior offerings of the Company will not be entitled to.

 

(vii) The
Subscriber (together with its Advisors, if any) has received all documents requested by the Subscriber or its agents (including that which
is attached hereto forming Annex A, Annex B, and Annex C), has carefully reviewed them and understands the information contained
therein, prior to the execution of this Agreement.

 

(c) The
Subscriber is not relying on the Company or any of its employees, agents, sub-agents or advisors with respect to the legal, tax, economic
and related considerations involved in this investment. The Subscriber has relied on the advice of, or has consulted with, only its Advisors.

 

(d) The
Subscriber has carefully considered the potential risks relating to the Company and a purchase of the Securities, and fully understands
that the Securities are a speculative investment that involves a high degree of risk of loss of the Subscriber’s entire investment.
Among other things, the Subscriber has carefully considered each of the risks as described on Annex C, attached hereto.

 

(e) The
Subscriber will not sell or otherwise transfer any Securities without registration under the Securities Act or an exemption therefrom,
and fully understands and agrees that the Subscriber must bear the economic risk of its purchase because, among other reasons, the Securities
have not been registered under the Securities Act or under the securities laws of any state and, therefore, cannot be resold, pledged,
assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and under the applicable securities
laws of such states, or an exemption from such registration is available. In particular, the Subscriber is aware that the Securities are
“restricted securities,” as such term is defined in Rule 144 promulgated under the Securities Act (“Rule 144”),
and they may not be sold pursuant to Rule 144 unless all of the conditions of Rule 144 are met. The Subscriber understands that any sales
or transfers of the Securities are further restricted by state securities laws.

 

(f) No
oral or written representations or warranties have been made, or information furnished, to the Subscriber or its Advisors, if any, by
the Company or any of its officers, employees, agents, sub-agents, affiliates, advisors or subsidiaries in connection with the Offering,
other than any representations of the Company contained herein, and in subscribing for the Securities, the Subscriber is not relying upon
any representations other than those contained herein.

 

(g) The
Subscriber’s overall commitment to investments that are not readily marketable is not disproportionate to the Subscriber’s
net worth, and an investment in the Securities will not cause such overall commitment to become excessive.

 

(h)
The Subscriber understands and agrees that the certificates for the Securities shall bear substantially the following legend until
(i) such Securities shall have been registered under the Securities Act and effectively disposed of in accordance with a registration
statement that has been declared effective or (ii) in the opinion of counsel acceptable to the Company, such Securities may be sold without
registration under the Securities Act, as well as any applicable “blue sky” or state securities laws:

 

“THE SHARES
REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”),
OR ANY APPLICABLE STATE SECURITIES LAWS. SUCH SHARES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND MAY NOT BE OFFERED FOR SALE, SOLD,
DELIVERED AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FILED BY THE ISSUER WITH
THE U.S. SECURITIES AND EXCHANGE COMMISSION COVERING SUCH SHARES UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL THAT SUCH REGISTRATION
IS NOT REQUIRED.

any.

 

(k) In
making the decision to invest in the Securities the Subscriber has relied solely upon the information provided by the Company in the Transaction
Documents. To the extent necessary, the Subscriber has retained, at its own expense, and relied upon appropriate professional advice regarding

reliance on any statements made or information provided by any person or entity in the course of Subscriber’s consideration of an
investment in the Securities other than the Transaction Documents.

 

(l) The
Subscriber has taken no action that would give rise to any claim by any person for brokerage commissions, finders’ fees or the like
relating to this Agreement or the transactions contemplated hereby.

 

(m) The
Subscriber is not relying on the Company or any of its employees, agents, or advisors with respect to the legal, tax, economic and related
considerations of an investment in the Securities, and the Subscriber has relied on the advice of, or has consulted with, only its own
Advisors.

(n) The
Subscriber acknowledges that any estimates or forward-looking statements or projections furnished by the Company to the Subscriber were
prepared by the management of the Company in good faith, but that the attainment of any such projections, estimates or forward-looking
statements cannot be guaranteed by the Company or its management and should not be relied upon.

 

(o) No
oral or written representations have been made, or oral or written information furnished, to the Subscriber or its Advisors, if any, in
connection with the Offering that are in any way inconsistent with the information contained herein.

 

(p) (For
ERISA plans only) The fiduciary of the ERISA plan (the “Plan”) represents that such fiduciary has been informed of
and understands the Company’s investment objectives, policies and strategies, and that the decision to invest “plan assets”
(as such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets
and impose other fiduciary responsibilities. The Subscriber or Plan fiduciary (i) is responsible for the decision to invest in the Company;
(ii) is independent of the Company and any of its affiliates; (iii) is qualified to make such investment decision; and (iv) in making
such decision, the Subscriber or Plan fiduciary has not relied primarily on any advice or recommendation of the Company or any of its
affiliates.

 

    7

     

    

 

(q) This
Agreement is not enforceable by the Subscriber unless it has been accepted by the Company, and the Subscriber acknowledges and agrees
that the Company reserves the right to reject any subscription for any reason or for no reason.

 

(r) The
Subscriber will indemnify and hold harmless the Company and, where applicable, its directors, officers, employees, agents, advisors, affiliates
and shareholders, and each other person, if any, who controls any of the foregoing from and against any and all loss, liability, claim,
damage and expense whatsoever (including, but not limited to, any and all fees, costs and expenses whatsoever reasonably incurred in investigating,
preparing or defending against any claim, lawsuit, administrative proceeding or investigation whether commenced or threatened) (a “Loss”)
arising out of or based upon any representation or y of the Subscriber contained herein or in any document furnished by the Subscriber

RISK FACTORS

 

An investment
in the Securities of the Company involves a high degree of risk and should be considered only by persons who can afford to lose their
entire investment and who have no need for liquidity in their investment. You should carefully consider the risk factors described below,
and discussed in the section titled “Risk Factors” in our most recent Annual Report on Form 10-K, as well as the risks, uncertainties
and additional information set forth in our SEC Filings incorporated by reference herein. Our business, financial condition or results
of operations could be materially adversely affected by any of these risks. The trading price of our common stock could decline due to
any of these risks, and you may lose all or part of your investment.

 

Risks Related to the Securities and This Offering

 

There is no public market
for the Series X Preferred Shares and a limited public market for the common stock.

 

There is no public
market for the Series X Preferred Shares, and we do not intend to have such securities quoted or listed on any market. In addition, our
common stock is quoted on the OTC Pink which is an unorganized, inter-dealer, over-the-counter market which provides significantly less
liquidity than the NASDAQ Capital Market or other national securities exchange. These factors may have an adverse impact on the trading
and price of our common stock.

 

The Securities will be subject to restrictions
on resale.

 

We have not registered
the sale of any of the Securities under the Securities Act or any state securities laws. The securities offered hereby are highly illiquid,
and are not transferable except in accordance with the Securities Act. Consequently, the Securities may not be resold or otherwise transferred
unless they are subsequently registered under applicable securities laws or an exemption therefrom is available. In view of these and
other limitations to the transfer of the Securities as described herein, the Securities should be considered an illiquid investment that
may need to be held indefinitely. Limitations on the transfer of the Securities may also adversely affect the price that a Subscriber
might be able to obtain for such securities in a private sale.

 

The price of the Series X Preferred
Shares has been determined without a third party valuation or fairness opinion.

 

We have set the
price of the Series X Preferred Shares without the benefit of any third party valuation or fairness opinion or review. You must make your
own determination as to the accuracy, fairness or reasonableness of the price of the Series X Preferred Shares and the other terms of
the Offering.

 

We will have
significant discretion over the use of the gross proceeds.

 

The Company intends
to use the net proceeds of this Offering for funding its business operations, and the Company shall have discretion to use any of such
net proceeds for its general corporate purposes and to meet working capital needs. Accordingly, Company management will have broad discretion
as to the application of such proceeds. There can be no assurance that management’s use of proceeds generated through this Offering
will prove optimal or translate into revenue or profitability for the Company.

 

    16

     

    

 

There is no investor counsel.

 

The Company has
not retained any independent professionals to review or comment on this Offering or otherwise protect the interests of Subscribers. Although
the Company has retained its own counsel, neither such firm nor any other firm has made any independent examination of any factual matters
represented by management herein, and purchasers of the Securities offered hereby should not rely on any such firms so retained with respect
to any matters herein described.

 

No governmental entity has evaluated
our securities.

 

No federal or state
commission, department or agency has made any evaluation, finding, recommendation or endorsement with respect to the Securities.

 

Additional stock offerings
in the future may dilute then-existing shareholders’ percentage ownership of the Company.

 

Given our plans and
expectations that we will need additional capital and personnel, we anticipate that we will need to issue additional shares of common
stock or securities convertible or exercisable for shares of common stock, including convertible preferred stock, convertible notes, stock
options or warrants. The issuance of additional securities in the future will dilute the percentage ownership of then current stockholders.
Without limiting the generality of the foregoing, the Company may conduct other offerings concurrent with this offering.

 

The Series X Preferred Shares will
not have voting rights.

 

Holders of the
Series X Preferred Shares, by virtue of holding such shares, will not have any voting rights, except as may be required under applicable
law. Thus, the holders of the Series X Preferred Shares, by virtue of holding such shares, will have no right to participate in the election
of directors of the Company or any other matter that may be brought to the vote of the shareholders of the Company.

 

The Series X Preferred Shares will
be subject to the Company’s right of redemption.

 

In addition to
the Subscribers right to cause the Company to redeem the Subscriber’s Series X Preferred Stock after the one-year anniversary of
this Subscription Agreement at the redemption price of 125% of the Aggregate Purchase Price, pursuant to the Series X Certificate of Designation,
the Company will have the right to redeem outstanding shares of Series X Preferred Stock at any time in the Company’s discretion,
subject to the terms and conditions set forth therein.

 

Investors should consult
their own tax advisers regarding tax consequences of this Offering, the Series X Preferred Shares, and the Added Common Shares.

 

The Company makes
no representations regarding the tax treatment that will apply to the Series X Preferred Shares, the Added Common Shares or this Offering,
including, without limitation, with respect to any dividend or redemption payments under the Series X Preferred Shares. Subscribers should
consult their own tax advisers regarding such tax consequences.
