Section 2.02          Execution
and Authentication.

 

One Officer must sign the Notes for the
Company by manual signature, Electronic Signature (as defined below) or facsimile 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 or Electronic Signature of the Trustee. The signature will be conclusive evidence
that the Note has been authenticated under this Supplemental Indenture.

 

The Trustee shall,
upon receipt of a written order of the Company signed by at least one Officer (an “Authentication Order”), authenticate
Notes for original issue under this Supplemental Indenture, including any Additional Notes issued pursuant to Section 2.05
hereof. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes
authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07
of the Base Indenture.

 

The Trustee may appoint
an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Supplemental 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, the Company or an Affiliate of the Company.

The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders.

REDEMPTION AND PREPAYMENT

 

Section 3.01         Notices
to Trustee.

 

If the Company elects to redeem Notes of
a Series pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee,
at least 15 days (or such shorter period as the Trustee may in its sole discretion allow) but not more than 60 days before a redemption
date, an Officer’s Certificate setting forth:

 

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

 

		(2)	the redemption date;

 

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

 

(4)            the
redemption price or, where the redemption price cannot be calculated at the time of such notice, the method of calculation thereof.

 

Section 3.02         Selection
of Notes to Be Redeemed or Purchased.

 

If less than all of
the Notes of a Series are to be redeemed at any time, the Trustee shall select Notes of such Series for redemption on
a pro rata basis among all outstanding Notes of such Series or, if the Notes of such Series are listed on any
national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes
of such Series are listed, in either case, unless otherwise required by law or depositary requirements.

 

    31

     

    

 

In the event of partial
redemption by lot, the particular Notes of such Series to be redeemed or purchased shall be selected, unless otherwise provided
herein, not less than 10 nor more than 60 days prior to the redemption by the Trustee from the outstanding Notes of such Series not
previously called for redemption.

 

The Trustee shall promptly
notify the Company in writing of the Notes of a Series 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 of a Series selected shall be in amounts
of $2,000 or whole multiples of $1,000 in excess of $2,000; except that if all of the Notes of such Series of a Holder are
to be redeemed or purchased, the entire outstanding amount of Notes of such Series held by such Holder, even if not a multiple
of $1,000 shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Supplemental Indenture
that apply to Notes of such Series called for redemption also apply to portions of Notes of such Series called for redemption.

 

No Notes of $2,000
or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail or delivered electronically at least
10 but not more than 60 days before the redemption date to each Holder of Notes of a Series to be redeemed at its registered
address, except that redemption notices may be mailed or delivered electronically more than 60 days prior to a redemption date
if the notice is issued in connection with a defeasance of the Notes of such Series or a satisfaction and discharge of this
Supplemental Indenture.

 

If any Note of a Series is
to be redeemed in part only, the notice of redemption that relates to that Note of such Series shall state the portion of
the principal amount of that Note of such Series that is to be redeemed. A new Note of a Series in principal amount equal
to the unredeemed portion of the original Note of such Series shall be issued in the name of the Holder of Notes of such Series upon
cancellation of the original Note of such Series. Notes of a Series called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest ceases to accrue on Notes of a Series or portions of them called for
redemption.

 

Section 3.03          Notice
of Redemption.

 

At least 10 days but
not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, or delivered
electronically, a notice of redemption to each Holder whose Notes of a Series are to be redeemed at its registered address,
except that redemption notices may be mailed or delivered more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes of such Series or a satisfaction and discharge of this Supplemental Indenture
pursuant to Articles 8 or 11 hereof.

 

The notice will identify the Notes of a Series to
be redeemed and will state:

 

		(1)	the redemption date;

 

(2)            the
redemption price or, where the redemption price cannot be calculated at the time of such notice, the method 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 of such Series 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;

 

    32

     

    

 

(5)            that
Notes of such Series called for redemption must be surrendered to the Paying Agent to collect the redemption price;

 

(6)            that,
unless the Company defaults in making such redemption payment, interest on Notes of such Series called for redemption ceases
to accrue on and after the redemption date;

 

(7)            the
paragraph of the Notes of such Series and/or Section of this Supplemental Indenture pursuant to which the Notes of such
Series called for redemption are being redeemed; and

 

(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 of such Series.

 

At the Company’s
request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however,
that the Company has delivered to the Trustee, at least four (4) Business Days prior to the date such notice of redemption
is to be distributed to the Holders (or such shorter period as the Trustee in its sole discretion may allow), an Officer’s
Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

 

Any redemption and
notice thereof may, in the Company’s discretion, be subject to the satisfaction of one or more conditions precedent.

 

Section 3.04          Effect
of Notice of Redemption.

 

Once notice of redemption
is mailed or delivered in accordance with Section 3.03 hereof, Notes of a Series called for redemption become,
subject to any conditions precedent set forth in the notice of redemption, irrevocably due and payable on the redemption date at
the redemption price.

 

Section 3.05          Deposit
of Redemption or Purchase Price.

 

No later than 10:00
a.m. Eastern Time on the redemption or purchase date, the Company shall deposit with the Trustee or with the Paying Agent
money sufficient to pay the redemption or purchase price of, accrued interest and premium, if any, on all Notes of a Series to
be redeemed or purchased on that date. Promptly after the Company’s written request, the Trustee or the Paying Agent shall
promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts
necessary to pay the redemption or purchase price of, accrued interest and premium, if any, on, all Notes of such Series to
be redeemed or purchased.

 

If the Company complies
with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on
the Notes or the portions of Notes of a Series called for redemption or purchase. If a Note of a Series is redeemed or
purchased 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 of such Series was registered at the close of business on such
record date. If any Note of a Series called for redemption or purchase is not so paid upon surrender for redemption or purchase
because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from
the redemption or purchase 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 of such Series and in Section 4.01 hereof.

 

Section 3.06          Notes
Redeemed or Purchased in Part.

 

Upon surrender of a
Note of a Series that is redeemed or purchased in part, the Company shall issue and, upon receipt of an Authentication Order,
the Trustee shall authenticate for the Holder at the expense of the Company a new Note of such Series equal in principal amount
to the unredeemed or unpurchased portion of the Note surrendered.

The Company shall pay or cause to be paid
the principal of, premium, if any, and interest on, the Notes on the dates and in the manner provided in the Notes. Principal,
premium, if any, and interest will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary

and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written

The Company 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; provided, however, that no such designation or rescission
will in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City
of New York for such purposes. The Company 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.

or not required by the SEC’s rules and regulations, so long as any Notes of a Series are outstanding, the Company
shall furnish to Holders of such Series or cause the Trustee to furnish to the Holders of Notes of such Series, 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 Company were required

(2)           all
current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

 

All such reports shall
be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each
annual report on Form 10-K will include a report on the Company’s consolidated financial statements by the Company’s
independent registered public accounting firm. In addition, the Company shall file a copy of each of the reports referred to in
clauses (1) and (2) above with the SEC for public availability within the time periods specified in the rules and
regulations applicable to such reports (unless the SEC will not accept such a filing). To the extent such filings are made, the
reports shall be deemed to be furnished to the Trustee and Holders of Notes. The Trustee shall not be responsible for determining
whether such filings have been made.

 

If, at any time, the
Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless
continue filing the reports specified in this Section 4.03(a) with the SEC within the time periods specified above
unless the SEC will not accept such a filing. The Company agrees that it shall not take any action for the purpose of causing the
SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for
any reason, the Company shall post the reports referred to in this Section 4.03(a) on its website within the time
periods that would apply if the Company were required to file those reports with the SEC.

addition, the Company and the Guarantors agree that, for so long as any Notes of a Series remain outstanding, at any time
they are not required to file the reports required by the preceding paragraphs with the SEC, they shall furnish to the Holders
of such Series and to securities analysts and prospective investors, upon their request, the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act.

 

(c)           Delivery
of the reports and documents described above to the Trustee is for informational purposes only, and the Trustee’s receipt
of such shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee
is entitled to conclusively rely on an Officer’s Certificate).

 

Section 4.04          Compliance
Certificate.

 

(a)           The
Company 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 Company and its Subsidiaries during the preceding fiscal year has been made under
the supervision of the signing Officer(s) with a view to determining whether the Company has kept, observed, performed and
fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to
the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this
Indenture 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 Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge
no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, and
interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company
is taking or proposes to take with respect thereto.

 

(b)           So
long as any of the Notes are outstanding, the Company shall deliver to the Trustee, forthwith upon any Officer becoming aware of
any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

Section 4.05          Taxes.

 

The Company shall pay,
and shall 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 Company and each
of the Guarantors covenant (to the extent that they may lawfully do so) that they shall 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 in force, that may affect the covenants or the performance of the Indenture; and the Company and each of the
Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant
that they shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee,
but shall suffer and permit the execution of every such power as though no such law has been enacted.

 

Section 4.07          Liens.

 

The Company will not,
and will not permit any Guarantor to, create or permit to exist any Lien upon any Principal Property owned by the Company or any
Guarantor or upon any Equity Interests issued by, or Indebtedness of, any direct or indirect Subsidiary of the Company to secure
any Indebtedness of the Company or any Guarantor without providing for the Notes to be equally and ratably secured with (or prior
to) any and all such Indebtedness and any other Indebtedness similarly entitled to be equally and ratably secured for so long as
such Indebtedness is so secured; provided, however, that this restriction will not apply to, or prevent the creation or
existence of:

 

(1)            Liens
securing Indebtedness of the Company or any Guarantor under one or more Credit Facilities in an aggregate principal amount, measured
as of the date of creation of any such Lien and the date of incurrence of any such Indebtedness, not exceeding the greatest of
(a) 30% of Total Assets, (b) $10.0 billion and (c) such amount as would not cause the Secured Leverage Ratio to
exceed 3.5 to 1.0;

 

		(2)	Existing Liens;

 

(3)            Liens
securing Indebtedness of any Person that (a) is acquired by the Company or any of its Subsidiaries after the date hereof,
(b) is merged or amalgamated with or into the Company or any of its Subsidiaries after the date hereof or (c) becomes
consolidated in the financial statements of the Company or any of its Subsidiaries after the date hereof in accordance with GAAP;
provided, however, that in each case contemplated by this clause (3), such Indebtedness was not incurred in contemplation
of such acquisition, merger, amalgamation or consolidation and is only secured by Liens on the Equity Interests and assets of,
the Person (and Subsidiaries of the Person) acquired by, or merged or amalgamated with or into, or consolidated in the financial
statements of, the Company or any of its Subsidiaries;

 

(4)            Liens
securing Indebtedness of the Company or any Guarantor incurred to finance (whether prior to or within 365 days after) the acquisition,
construction or improvement of assets (whether through the direct purchase of assets or through the purchase of the Equity Interests
of any Person owning such assets or through an acquisition of any such Person by merger); provided, however, that such Indebtedness
is only secured by Liens on the Equity Interests and assets acquired, constructed or improved in such financing (and related contracts,
intangibles, and other assets that are incidental thereto or arise therefrom (including accessions thereto and replacements or
proceeds thereof));

 

    39

     

    

 

		(5)	Liens in favor of the Company or any of its Subsidiaries;

 

(6)          Liens
securing Hedging Obligations; provided that such agreements were not entered into for speculative purposes (as determined
by the Company in its reasonable discretion acting in good faith);

 

(7)          Liens
relating to current or future escrow arrangements securing Indebtedness of the Company or any Guarantor;

 

(8)          Liens
to secure Environmental CapEx Debt or Necessary CapEx Debt that encumber only the assets purchased, installed or otherwise acquired
with the proceeds of such Environmental CapEx Debt or Necessary CapEx Debt;

 

(9)          Liens
encumbering deposits made to secure obligations arising from statutory, regulatory, contractual or warranty requirements of the
Company or any Guarantor, including rights of offset and set-off;

 

(10)        Liens
arising in relation to any securitization or other structured finance transaction where (a) the primary source of payment
of any obligations of the issuer is linked or otherwise related to cash flow from particular property or assets (or where payment
of such obligations is otherwise supported by such property or assets) and (b) recourse to the issuer in respect of such obligations
is conditional on cash flow from such property or assets;

 

		(11)	Refinancing Liens;

 

(12)        Liens
on the stock or assets of Project Subsidiaries securing Project Debt or tax equity financing of one or more Project Subsidiaries;
and

 

(13)        other
Liens, in addition to those permitted in clauses (1) through (12) above, securing Indebtedness having an aggregate principal
amount, measured as of the date of creation of any such Lien and the date of incurrence of any such Indebtedness, not to exceed
the greater of (i) 3% of Total Assets and (ii) $750.0 million.

 

Liens securing Indebtedness
under the Credit Agreement existing on the date of this Supplemental Indenture will be deemed to have been incurred on such date
in reliance on the exception provided by clause (1) above. For purposes of determining compliance with this Section 4.07,
in the event that a Lien meets the criteria of more than one of the categories described in clauses (1) through (13) above,
the Company (a) will be permitted, in its sole discretion, to (i) classify such Lien on the date of incurrence and may
later reclassify such Lien in any manner (based on the circumstances existing at the time of any such reclassification) and (ii) divide
and redivide the amount of such Lien arising among more than one of such clauses and (b) will only be required to include
such Lien in one of any such clauses.

 

If the Company or any
Guarantor proposes to create or permit to exist any Lien upon any Principal Property owned by the Company or any Guarantor or upon
any Equity Interests or Indebtedness of any direct or indirect Subsidiary of the Company to secure any Indebtedness, other than
as permitted by clauses (1) through (13) of the previous paragraph, the Company will give prior written notice thereof to
the Trustee, who will give notice to the Holders of the Notes at the direction and expense of the Company, and the Company will
further agree, prior to or simultaneously with the creation of such Lien, effectively to secure all the Notes equally and ratably
with (or prior to) such other Indebtedness, for so long as such other Indebtedness is so secured.

Section 4.08         Corporate
Existence.

 

Subject to Article 5
hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect:

 

(1)          its
corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and

 

(2)          the
rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries;

 

provided, however, that
the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence
of any of its Subsidiaries, if (a) the Company shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders of the Notes or (b) if a Subsidiary is to be dissolved, such Subsidiary has no assets.

 

Section 4.09         Offer
to Repurchase Upon Change of Control Triggering Event.

 

(a)          Upon
the occurrence of a Change of Control Triggering Event, the Company will make an offer (a “Change of Control Offer”)
to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder’s
Notes of a Series at a purchase price in cash equal to 101% of the aggregate principal amount of Notes of such Series repurchased,
plus accrued and unpaid interest, if any, on the Notes of such Series repurchased to the date of purchase, subject to the
rights of Holders of Notes of such Series on the relevant record date to receive interest due on the relevant interest payment
date (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the
Company will mail (or deliver electronically) a notice to each Holder describing the transaction or transactions that constitute
the Change of Control and stating:

 

(1)          that
the Change of Control Offer is being made pursuant to this Section 4.09 and that all Notes of such Series tendered
will be accepted for payment;

 

(2)          the
purchase price and the purchase date, which shall be no earlier than 10 days and no later than 60 days from the date such notice
is mailed or delivered (the “Change of Control Payment Date”);

 

		(3)	that any Note of such Series not tendered will continue to accrue interest;

 

(4)          that,
unless the Company defaults in the payment of the Change of Control Payment, all Notes of such Series accepted for payment
pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

 

(5)          that
Holders electing to have any Notes of such Series purchased pursuant to a Change of Control Offer shall be required to surrender
the Notes of such Series, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes of
such Series completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date;

 

    41

     

    

 

(6)          that
Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second
Business Day preceding the Change of Control Payment Date, facsimile transmission or letter setting forth the name of the Holder,
the principal amount of Notes of such Series delivered for purchase, and a statement that such Holder is withdrawing his election
to have the Notes of such Series purchased; and

 

(7)          that
Holders whose Notes of such Series are being purchased only in part will be issued new Notes of such Series equal in
principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal
amount or an integral multiple of $1,000 in excess of $2,000.

 

The Company shall comply
with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the repurchase of the Notes of a Series as a result of
a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.09, the Company shall comply with the applicable securities laws and regulations and shall
not be deemed to have breached its obligations under this Section 4.09 by virtue of such compliance.

 

(b)          On
the Change of Control Payment Date, the Company shall, to the extent lawful:

 

(1)          accept
for payment all Notes or portions of Notes of a Series 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 of such Series properly
tendered; and

 

(3)          deliver
or cause to be delivered to the Trustee the Notes of such Series properly accepted together with an Officer’s Certificate
stating the aggregate principal amount of Notes of such Series or portions of Notes of such Series being purchased by
the Company.

 

The Paying Agent shall
promptly distribute to each Holder of Notes of a Series properly tendered the Change of Control Payment for the Notes of such
Series, and the Trustee shall promptly authenticate and deliver (or cause to be transferred by book entry) to each Holder a new
Note of such Series equal in principal amount to any unpurchased portion of the Notes of such Series surrendered, if
any; provided that each new Note of such Series shall be in a principal amount of $2,000 or an integral multiple of
$1,000 in excess of $2,000. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Payment Date.

 

(c)          The
provisions described in Section 4.09(a) and (b) shall apply whether or not other provisions of this
Supplemental Indenture are applicable. Except as described in Section 4.09(a) and (b) hereof, Holders
of Notes of such Series shall not be permitted to require that the Company repurchase or redeem the Notes of such Series in
the event of a takeover, recapitalization or similar transaction.

 

(d)          Notwithstanding
anything to the contrary in this Section 4.09, the Company shall 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 Section 4.09 and purchases all Notes of a Series properly
tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption with respect to the applicable Series has
been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption
price. A Change of Control Offer may be made in advance of a Change of Control Triggering Event, with the obligation to pay and
the timing of payment conditioned upon the occurrence of a Change of Control Triggering Event, if a definitive agreement to effect
a Change of Control is in place at the time the Change of Control Offer is made.

 

    42

     

    

 

(e)          If
Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes of a Series validly tender and do not
withdraw such Notes of such Series in a Change of Control Offer and the Company, or any third party making a Change of Control
Offer in lieu of the Company in accordance with Section 4.09(d)(1), purchases all of the Notes of such Series validly
tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 10 nor more than 60 days’
prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all Notes
of such Series that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change
of Control Payment, plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, to
the date of redemption. In determining whether the Holders of at least 90.0% of the aggregate principal of the then outstanding
Notes of such Series have validly tendered and not withdrawn such Notes of such Series in a Change of Control Offer,
such calculation shall include all Notes of such Series owned by an Affiliate of the Company (notwithstanding any provision
of this Supplemental Indenture to the contrary).

 

Section 4.10          Additional
Subsidiary Guarantees.

 

If,

 

(1)          the
Company or any of its Subsidiaries acquires or creates another Subsidiary after the date of this Supplemental Indenture and such
Subsidiary Guarantees any Obligations of the Company under the Credit Agreement, or

 

(2)          any
Subsidiary that does not Guarantee any Obligations of the Company under the Credit Agreement as of the date of this Supplemental
Indenture (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time) subsequently Guarantees
any Obligations of the Company under the Credit Agreement, or

 

(3)          if
there is no Indebtedness of the Company outstanding under the Credit Agreement at that time, any Subsidiary of the Company (including
any newly acquired or created Subsidiary) Guarantees any Obligations with respect to any other Additional Indebtedness,

 

then such newly acquired or created Subsidiary
or Subsidiary that subsequently Guarantees Obligations under the Credit Agreement or other Additional Indebtedness, as the case
may be, will become a Guarantor of the Notes and execute a supplemental indenture in the form attached hereto as Exhibit E
and deliver an Opinion of Counsel satisfactory to the Trustee within 60 business days of the date on which it was acquired or created
or guaranteed other Indebtedness for borrowed money of the Company, as the case may be.

the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to
the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor

in the acceleration of such Indebtedness prior to its express maturity,

 

and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, exceeds the greater of (i) 1.5% of Total Assets and (ii) $375.0
million; provided that this clause (4) shall not apply to (i) secured Indebtedness that becomes due as a result
of the voluntary sale or transfer of the property or assets securing such Indebtedness to a Person that is not an Affiliate of
the Company; (ii) Non-Recourse Debt (except to the extent that the Company or any of the Guarantors that are not parties to
such Non-Recourse Debt becomes directly or indirectly liable, including pursuant to any contingent obligation, for any such Non-Recourse Debt and such liability, individually or in the aggregate, exceeds the greater of (a) 1.5% of Total Assets and (b) $375.0
million), and (iii) to the extent constituting Indebtedness, any indemnification, guarantee or other credit support obligations
of the Company or any of the Guarantors in connection with any tax equity financing entered into by a non-Guarantor Subsidiary
or any standard securitization undertakings of the Company or any of the Guarantors in connection with any securitization or other
structured finance transaction entered into by a non-Guarantor Subsidiary;

 

(5)          except
as permitted by this Supplemental Indenture, any Subsidiary Guarantee of any Guarantor (or any group of Guarantors) that constitutes
a Significant Subsidiary shall be held in any final and non-appealable judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any Guarantor (or any group of Guarantors) that constitutes a Significant
Subsidiary, or any Person acting on behalf of any Guarantor (or any group of Guarantors) that constitutes a Significant Subsidiary,
shall deny or disaffirm its or their obligations under its or their Subsidiary Guarantee(s);

 

		(6)	the Company or any of the Guarantors of the Notes of such Series that is a Significant Subsidiary
or any group of Guarantors of the Notes of such Series that, taken together, would constitute a Significant Subsidiary:

 

		(A)	commences a voluntary case,

 

		(B)	consents to the entry of an order for relief against it in an involuntary case,

 

    45

     

    

 

(C)          consents
to the appointment of a custodian of it or for all or substantially all of its property,

 

		(D)	makes a general assignment for the benefit of its creditors, or

 

		(E)	generally is not paying its debts as they become due;

 

(7)          a
court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

 

(A)         is
for relief against the Company or any Guarantor of the Notes of such Series that is a Significant Subsidiary or any group
of Guarantors of the Notes of such Series that, taken together, would constitute a Significant Subsidiary;

 

(B)         appoints
a custodian of the Company or any Guarantor of the Notes of such Series that is a Significant Subsidiary or any group of Guarantors
of the Notes of such Series that, taken together, would constitute a Significant Subsidiary or for all or substantially all
of the property of the Company or any Guarantor of the Notes of such Series that is a Significant Subsidiary or any group
of Guarantors of the Notes of such Series that, taken together, would constitute a Significant Subsidiary; or

 

(C)         orders
the liquidation of the Company or any Guarantor of the Notes of such Series that is a Significant Subsidiary or any group
of Guarantors of the Notes of such Series that, taken together, would constitute a Significant Subsidiary;

 

and the order or decree remains unstayed
and in effect for 60 consecutive days; or

 

		(8)	the failure to consummate the Special Partial Mandatory Redemption, to the extent required, as
described under Section 3.08.

 

(b)          Any
notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration
or take any other action (a “Noteholder Direction”) provided by any one or more Holders of the then outstanding
Notes of a Series (each, a “Directing Holder”) must be accompanied by a written representation with a medallion
guaranteed signature from each such Holder to the Company and the Trustee that such Holder is not (or, in the case such Holder
is DTC or its nominee, that such Holder is being instructed solely by Beneficial Owners that are not) Net Short (a “Position
Representation”), which representation, in the case of a Noteholder Direction relating to a notice of Default (a “Default
Direction”) shall be deemed repeated at all times until the resulting Event of Default is cured or otherwise ceases to
exist or the Notes of such Series are accelerated. In addition, each Directing Holder must, at the time of providing a Noteholder
Direction, covenant to provide the Company with such other information as the Company may reasonably request from time to time
in order to verify the accuracy of such Directing Holder’s Position Representation within five Business Days of request therefor
(a “Verification Covenant”). In any case in which the Holder is DTC or its nominee, any Position Representation
or Verification Covenant required hereunder shall be provided by the Beneficial Owner of the Notes of such Series in lieu
of DTC or its nominee, and DTC shall be entitled to rely on such Position Representation and Verification Covenant in delivering
its direction to the Trustee.

 

    46

     

    

 

If, following the delivery
of a Noteholder Direction, but prior to acceleration of the Notes of the applicable Series, the Company determines in good faith
that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation
and provides to the Trustee an Officer’s Certificate stating that the Company has initiated litigation in a court of competent
jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and
seeking to invalidate any Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect
to such Event of Default shall be automatically stayed and the cure period with respect to such Event of Default shall be automatically
reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such
matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes of such Series, the Company
provides to the Trustee an Officer’s Certificate stating that a Directing Holder failed to satisfy its Verification Covenant,
the cure period with respect to such Event of Default shall be automatically stayed and the cure period with respect to any Event
of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed until
such time as the Company provides the Trustee with an Officer’s Certificate that the Verification Covenant has been satisfied;
provided that the Company shall promptly deliver such Officer’s Certificate to the Trustee upon becoming aware that the Verification
Covenant has been satisfied. Any breach of the Position Representation (as evidenced by the delivery to the Trustee of the Officer’s
Certificate stating that a Directing Holder failed to satisfy its Verification Covenant) shall result in such Holder’s participation
in such Noteholder Direction being disregarded; and if, without the participation of such Holder, the percentage of Notes of such
Series held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide
such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Event of Default shall
be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction
or any notice of such Default or Event of Default.

 

Notwithstanding anything
in the preceding two paragraphs to the contrary, (i) any Noteholder Direction delivered to the Trustee during the pendency
of an Event of Default specified in clause (6) or (7) of Section 6.01(a) shall not require compliance
with the foregoing paragraphs and (ii) a notice of Default may not be given with respect to any action taken, and reported
publicly or to Holders, more than two years prior to such notice of Default. The Trustee shall have no obligation to monitor or
determine whether a Holder is Net Short and can rely conclusively on a Directing Holder’s Position Representation, the Officer’s
Certificates delivered by the Company and determinations made by a court of competent jurisdiction.

 

Section 6.02          Acceleration.

 

In the case of an Event
of Default specified in clause (6) or (7) of Section 6.01(a) hereof, with respect to the Company, any
Guarantor of the Company that is a Significant Subsidiary or any group of Guarantors of the Company that, taken together, would
constitute a Significant Subsidiary, all outstanding Notes of such Series 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 of such Series may declare all the Notes of such Series to be
due and payable immediately. Upon any such declaration, the Notes of such Series shall become due and payable immediately.

 

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, if any,
or interest on, the Notes of a Series or to enforce the performance of any provision of the Notes of such Series or this
Indenture.

 

The Trustee may maintain
a proceeding even if it does not possess any of the Notes of such Series or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder of a Note of such Series 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.

 

    47

     

    

 

Section 6.04         Waiver
of Past Defaults.

 

The Holders of a majority
in aggregate principal amount of the then outstanding Notes of a Series by written notice to the Trustee may, on behalf of
the Holders of all of the Notes of such Series waive any existing Default or Event of Default and its consequences hereunder,
except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes
of such Series (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 of such Series 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 the 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.

 

Subject to certain
limitations, Holders of a majority in principal amount of the Notes of each Series that are then outstanding may direct the
time, method and place of conducting any proceeding for exercising any remedy available to the Trustee in its exercise of any trust
or power. 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 of a Series or that may involve the Trustee in personal
liability.

 

Section 6.06         Limitation
on Suits.

 

No Holder of a Note may pursue any remedy with respect
to this Indenture or the Notes 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 of such Series make a written request to the Trustee
to pursue the remedy;

 

(3)          such
Holder or Holders have offered the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability
or expense it may incur;

 

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

 

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

 

A Holder of a Note
may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

 

Section 6.07         Rights
of Holders of Notes to Receive Payment.

 

Notwithstanding any
other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium, if any, or interest
on, the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or
to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without
the consent of such Holder.

 

Section 6.08         Collection
Suit by Trustee.

 

If an Event of Default
specified in Section 6.01(a)(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 Company for the whole amount of principal of,
premium, if any, and interest on, remaining unpaid on, the Notes of a Series 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.

 

    48

     

    

 

Section 6.09         Trustee
May File Proofs of Claims.

 

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 of the Notes allowed in any judicial proceedings relative to the Company (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 to the Trustee under this Indenture, including without limitation,
under Section 7.01 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 to the Trustee under this Indenture, including without limitation,
under Section 7.01 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.

 

Section 6.10         Priorities.

 

If the Trustee collects
any money pursuant to this Article 6 or, after an Event of Default, any money or other property distributable in respect
of the Company’s obligations under this Indenture, such money shall be applied in the following order:

 

First:
to the Trustee, its agents and attorneys for amounts due under Section 7.07 of the Base Indenture, 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 of Notes of a Series for amounts due and unpaid on the Notes of such Series for principal, premium, if any,
and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes of such
Series for principal, premium, if any, and interest, respectively; and

 

Third:
to the Company 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 of a Note pursuant to Section 6.07
hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

ARTICLE 7

 TRUSTEE

 

Section 7.01         Compensation
and Indemnity.

 

(a)          The
Company will pay to the Trustee compensation as agreed in writing from time to time for its acceptance of this Indenture and services
hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The
Company 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. The Trustee may earn compensation in the form of short- term interest on items
like uncashed distribution checks (from the date issued until the date cashed), funds that the Trustee is directed not to invest,
deposits awaiting investment direction or received too late to be invested overnight in previously directed investments.

 

(b)          The
Company and the Guarantors will 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 fees and expenses
of counsel), including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this
Section 7.01) and defending itself against any claim (whether asserted by the Company, 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 its gross negligence, bad faith or willful misconduct.
The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify
the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor
will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will
pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without
its consent, which consent will not be unreasonably withheld.

 

(c)          The
obligations of the Company and the Guarantors under this Section 7.01 will survive the satisfaction and discharge of
this Indenture.

 

(d)          To
secure the Company’s and the Guarantors’ payment obligations in this Section 7.01, the Trustee will have
a Lien prior to the Notes of a Series on all money or property held or collected by the Trustee, except that held in trust
to pay principal of, premium, if any, or interest on, particular Notes of such Series. 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 (6) or (7) of Section 6.01(a) 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.

 

(f)          The
Company’s and Guarantors’ obligations under this Section 7.01 shall survive the resignation or removal
of the Trustee, any termination of this Supplemental Indenture, including any termination or rejection of this Supplemental Indenture
in any insolvency or similar proceeding and the repayment of all the Notes of a Series.

 

    50

     

    

 

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

 

Section 8.01         Option
to Effect Legal Defeasance or Covenant Defeasance.

 

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

 

Section 8.02         Legal
Defeasance and Discharge.

 

Upon the Company’s
exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each
of the Guarantors shall, 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 of a Series (including the Subsidiary
Guarantees) on the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Legal
Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Notes of such Series (including the Subsidiary Guarantees),
which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the
other Sections of the Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations
under such Notes of such Series, the Subsidiary Guarantees and this Supplemental Indenture and, to the extent applicable, the Base
Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments 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 of such Series to receive payments in respect of the principal of, premium, if any,
or interest on such Notes of such Series when such payments are due from the trust referred to in Section 8.04
hereof;

 

(2)          the
Company’s obligations with respect to such Notes of such Series under Article 2 and Section 4.02
hereof;

 

(3)          the
rights, powers, trusts, duties, indemnities and immunities of the Trustee hereunder and under the Base Indenture, and the Company’s
and the Guarantors’ obligations in connection therewith; and

 

(4)          this
Article 8.

 

Subject to compliance with this Article 8,
the Company 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 Company’s
exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Guarantors
shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their
obligations under Sections 4.07, 4.09 and 4.10 hereof with respect to the outstanding Notes of a Series on
and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”),
and the Notes of such Series 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 of such Series will
not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding
Notes of a Series and Subsidiary Guarantees, the Company and the Guarantors may omit to comply with and shall 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(a) hereof,
but, except as specified above, the remainder of the Indenture and such Notes of such Series and Subsidiary Guarantees shall
be unaffected thereby. In addition, upon the Company’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(a)(3), (4), (5) and (8) hereof shall not constitute Events of Default.

 

    51

     

    

 

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
Company 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, premium, if any, and interest
on, the outstanding Notes of a Series on the stated date for payment thereof or on the applicable redemption date, as the
case may be, and the Company must specify whether the Notes of such Series are being defeased to such stated date for payment
or to a particular redemption date;

 

(2)          in
the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that:

 

(A)         the
Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

 

(B)          since
the date of this Supplemental Indenture, there has been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders and Beneficial Owners of the outstanding
Notes of such Series 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 Company must deliver to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that the Holders and Beneficial Owners of the outstanding Notes of a Series 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 Company or any of the Guarantors is a party or by which the Company or any of the Guarantors is bound;

 

    52

     

    

 

(6)          the
Company must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of Notes of a Series over the other creditors of the Company with the intent of defeating,
hindering, delaying or defrauding any creditors of the Company or others; and

 

(7)          the
Company 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 of a Series shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Notes of such Series and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of such Series of
all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated
from other funds except to the extent required by law.

 

The Company shall 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 of such Series.

 

Notwithstanding anything
in this Article 8 to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the request
of the Company 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 Company.

 

Any money deposited
with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any,
or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due
and payable shall be paid to the Company on its written request or (if then held by the Company) will be discharged from such trust;
and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of
the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company 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 Company 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 shall be repaid to the Company.

 

    53

     

    

 

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 Company’s and the Guarantors’ obligations under the Indenture and
the Notes and the Subsidiary 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 Company makes any payment of principal of, premium,
if any, or interest on, any Note following the reinstatement of its obligations, the Company shall 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 Article 9
of the Base Indenture and Section 9.02 of this Supplemental Indenture, without the consent of any Holder of Notes of
a Series, the Company, the Guarantors and the Trustee may amend or supplement this Supplemental Indenture, the Notes of such Series or
the Subsidiary 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 (provided that such uncertificated Notes are
issued in registered form for U.S. tax purposes);

 

(3)          to
provide for the assumption of the Company’s Obligations to Holders of Notes of such Series in the case of a merger or
consolidation or sale of all or substantially all of the Company’s assets;

 

(4)          to
make any change that would provide any additional rights or benefits to the Holders of the Notes of such Series or that does
not adversely affect the legal rights under this Supplemental Indenture of any such Holder;

 

(5)          to
conform the text of this Supplemental Indenture or the Notes of such Series to any provision of the “Description of
the Notes” section of the Company’s Offering Memorandum;

 

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

 

(7)          to
provide for the issuance of Additional Notes in accordance with the limitations set forth in this Supplemental Indenture as of
the date hereof;

 

(8)          to
allow any Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes of such Series;

 

Upon the request of
the Company accompanied by a Board Resolution authorizing the execution of any such amendment or supplement, and upon receipt by
the Trustee of an Officer’s Certificate and Opinion of Counsel certifying that such amendment or supplement is authorized
or permitted by the terms of this Supplemental Indenture, the Trustee shall join with the Company and the Guarantors in the execution
of such amendment or supplement and make any further appropriate agreements and stipulations that may be therein contained, but
the Trustee shall not be obligated to enter into such amendment or supplement that affects its own rights, duties or immunities
under the Indenture or otherwise.

 

    54

     

    

 

Section 9.02         With Consent
of Holders of Notes.

 

Except as provided
below in this Section 9.02, the Company and the Trustee may amend or supplement this Supplemental Indenture (including,
without limitation, Section 4.09 hereof), the Notes of a Series, the Subsidiary Guarantees with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes of such Series then outstanding (including, without
limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, any Notes of such Series),
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, if any, or interest on, the Notes of such Series, except a payment
default resulting from an acceleration that has been rescinded) or compliance with any provision of this Supplemental Indenture,
such Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount
of the then outstanding Notes of such Series (including, without limitation, consents obtained in connection with a tender
offer or exchange offer for, or purchase of, the Notes of such Series). Section 2.08 of the Base Indenture shall determine
which Notes of such Series are considered to be “outstanding” for purposes of this Section 9.02.

 

Upon the request of
the Company accompanied by a Board Resolution and upon the filing with the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders of Notes of such Series as aforesaid, and upon receipt by the Trustee of an Officer’s Certificate
and Opinion of Counsel certifying that such amendment, supplement or waiver is authorized or permitted by the terms of this Supplemental
Indenture, the Trustee shall join with the Company and the Guarantors in the execution of such amendment, supplement or waiver
unless such amendment, supplement or waiver directly affects the Trustee’s own rights, duties or immunities under the Indenture
or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amendment, supplement
or waiver.

 

It is not necessary
for the consent of the Holders 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 Company shall mail or deliver electronically to
the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail
or deliver 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 and Section 8.02 of the
Base Indenture, the Holders of a majority in aggregate principal amount of the Notes of such Series then outstanding voting
as a single class may waive compliance in a particular instance by the Company with any provision of this Supplemental Indenture,
the Notes or the Subsidiary 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 of a Series held by a non-consenting Holder):

 

(1)          reduce
the principal amount of Notes of such Series 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 the provisions with respect to the redemption of the Notes of
such Series (other than provisions relating to the covenants described in Section 4.09 hereof and provisions relating
to the number of days’ notice to be given in case of redemption);

 

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

 

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

 

    55

     

    

 

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

 

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

 

(7)          waive
a redemption payment with respect to any Note (other than a payment required by Section 4.09 hereof); or

 

(8)          make
any change in Section 9.02 hereof or Section 9.02 of the Base Indenture, as to the Notes of such Series,
or in the preceding amendment and waiver provisions.

 

Other than as expressly provided in Section 9.02
above, the Base Indenture may only be amended, supplemented or otherwise modified as and to the extent provided in the Base Indenture.

 

Section 9.03         [Reserved].

 

Section 9.04         Revocation
and Effect of Consents.

 

Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note 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 of a Note or subsequent Holder of a Note 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.

 

Section 9.05         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 Company 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 9.06         Trustee
to Sign Amendments, etc.

 

Upon its receipt of
any documentation required to be delivered to it pursuant to this Article 9, the Trustee shall sign any amendment or
supplement 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 Company may not sign an amendment or supplement until the Board of Directors
of the Company approves it. In executing any amendment or supplement pursuant to this Article 9, the Trustee will be
entitled to receive and (subject to Section 7.01 of the Base Indenture) will be fully protected in relying upon an
Officer’s Certificate and an Opinion of Counsel stating that the execution of such amendment or supplement is authorized
or permitted by the Indenture.

ARTICLE 10

SUBSIDIARY GUARANTEES

 

Section 10.01.      Guarantee.

 

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

 

(1)          the
principal of, premium, if any, and interest on, the Notes shall be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on, the Notes, if lawful, and
all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall 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 shall 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.

 

(b)          The
Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability
of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes
with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, 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 Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant
that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes
and the Indenture.

 

(c)          If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the
Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, shall 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 Subsidiary 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 Subsidiary 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 Subsidiary 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 Subsidiary 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 Subsidiary 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 Subsidiary Guarantee not constituting
a fraudulent transfer or conveyance.

 

    57

     

    

 

Section 10.03.      Execution
and Delivery of Subsidiary Guarantee.

 

Each Guarantor hereby
agrees that its Subsidiary 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 Subsidiary Guarantee.

 

If an Officer whose
signature is on this Supplemental Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

 

The delivery of any
Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set forth
in this Supplemental Indenture on behalf of the Guarantors.

 

Section 10.04.      Guarantors
May Consolidate, etc., on Certain Terms.

 

Except as otherwise
provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets
to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than
the Company or another Guarantor, unless:

 

(1)          immediately
after giving effect to such transaction, no Default or Event of Default exists; and

 

(2)          subject
to Section 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by
or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under its Subsidiary
Guarantee and this Supplemental Indenture on the terms set forth herein pursuant to a supplemental indenture in form and substance
reasonably satisfactory to the Trustee;

 

In case of any such
consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed
and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the
due and punctual performance of all of the covenants and conditions of this Supplemental Indenture to be performed by the Guarantor,
such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein
as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon
all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All
the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Supplemental Indenture
as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Supplemental Indenture as though
all of such Subsidiary Guarantees had been issued at the date of the execution hereof.

 

Except as set forth
in Articles 4 and 5 hereof, and notwithstanding clause (2) above, nothing contained in this Supplemental Indenture
or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or
will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company
or another Guarantor.

 

    58

     

    

 

Section 10.05.      Releases.

 

		(a)	The Subsidiary Guarantee of a Guarantor of a Series of Notes shall be released automatically:

 

(1)          in
connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of
merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary
of the Company;

 

(2)          in
connection with any sale or other disposition of Capital Stock of that Guarantor to a Person that is not (either before or after
giving effect to such transaction) the Company or a Subsidiary of the Company, if following such sale or other disposition, that
Guarantor is not a direct or indirect Subsidiary of the Company;

 

(3)          upon
defeasance or satisfaction and discharge of such Series of Notes as provided in Sections 8.01, 8.02, 8.03,
8.04 and 11.01 hereof;

 

(4)          upon
the dissolution of a Guarantor that is permitted under this Supplemental Indenture; or

 

		(5)	otherwise with respect to the Guarantee of any Guarantor:

 

(A)         upon
the prior consent of Holders of at least a majority in aggregate principal amount of the applicable Series of Notes then outstanding;

 

(B)          if
the Company has Indebtedness outstanding under the Credit Agreement at that time, upon the consent of the requisite lenders under
the Credit Agreement to the release of such Guarantor’s Guarantee of all Obligations under the Credit Agreement, or, if there
is no Indebtedness of the Company outstanding under the Credit Agreement at that time, upon the requisite consent of the holders
of all other Indebtedness for borrowed money of the Company that is guaranteed by such Guarantor at that time outstanding to the
release of such Guarantor’s Guarantee of all Obligations with respect to all other Indebtedness for borrowed money that is
guaranteed by such Guarantor at that time outstanding; or

 

(C)          if
the Company has Indebtedness outstanding under the Credit Agreement at that time, upon the release of such Guarantor’s Guarantee
of all Obligations of the Company under the Credit Agreement, or, if there is no Indebtedness of the Company outstanding under
the Credit Agreement at that time, upon the release of such Guarantor’s Guarantee of all Obligations with respect to all
other Indebtedness for borrowed money of the Company at that time outstanding.

 

(b)          The
Subsidiary Guarantee of a Guarantor shall be released with respect to the Notes automatically upon Legal Defeasance, Covenant Defeasance
or satisfaction and discharge of this Supplemental Indenture pursuant to Articles 8 and 11 hereof.

 

(c)          Upon
delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that the action
or event giving rise to the applicable release has occurred or was made by the Company in accordance with the provisions of this
Supplemental Indenture the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor
from its obligations under its Guarantee.

 

(d)          Any
Guarantor not released from its obligations under its Subsidiary Guarantee as provided in this Section 10.05 will remain
liable for the full amount of principal of, premium, if any, and interest on, the Notes and for the other obligations of any Guarantor
under the Indenture as provided in this Article 10.

 

    59

     

    

 

ARTICLE 11

 SATISFACTION
AND DISCHARGE

 

Section 11.01         Satisfaction
and Discharge.

 

This Supplemental Indenture will be discharged
and will cease to be of further effect as to all Notes of a Series issued hereunder, when:

 

		(1)	either:

 

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

 

(b) all
Notes of such Series that have not been delivered to the Trustee for cancellation have become due and payable by reason of
the distribution of a notice of redemption or otherwise or will become due and payable within one year and the Company 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 of cash in U.S. dollars and non-callable Government
Securities, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge
the entire Indebtedness on the Notes of such Series not delivered to the Trustee for cancellation for principal, premium,
if any, and interest to the date of maturity or redemption;

 

(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 the deposit will not result in a breach or violation of, or constitute a default under, any other
instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound;

 

(3)           the
Company or any Guarantor has paid or caused to be paid all sums payable by it with respect to such Series of Notes under this
Supplemental Indenture; and

 

(4)           the
Company has delivered irrevocable instructions to the Trustee under this Supplemental Indenture to apply the deposited money toward
the payment of the Notes of such Series at maturity or on the redemption date, as the case may be.

 

In addition, the Company 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 Supplemental Indenture, 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.
In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07
of the Base Indenture, that, by their terms, survive the satisfaction and discharge of this Supplemental Indenture.

 

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 the Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal, premium, if any, and interest 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.

 

    60

     

    

 

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 Company’s and any Guarantor’s obligations under this Supplemental 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 Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement
of its obligations, the Company 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 Supplemental Indenture referred to below unless otherwise indicated.

 

(1) INTEREST.
NRG Energy, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal
amount of this Note at 3.375% per annum from December 2, 2020 until maturity. The Company shall pay interest
semi-annually in arrears on February 15 and August 15 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each, an “Interest Payment Date”). Interest on this Note 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 there is no existing Default in the payment of interest, and 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; provided, further, that the first Interest Payment Date shall be August 15, 2021. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

 

(2) METHOD
OF PAYMENT. The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are registered
Holders of Notes at the close of business on the February 1 and August 1 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 Base Indenture with respect to defaulted interest. The Notes will be payable as to principal,
premium, if any, and interest at the office or agency of the Paying Agent and Registrar within the City and State of New
York, or, at the option of the Company, payment of interest 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, if any, and interest on, all Global Notes and all other Notes the Holders of
which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall 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, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying
Agent and Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Notes.
The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

 

(4)  INDENTURE.
This Note is one of a duly authenticated series of securities of the Company issued and to be issued in one or more series
under an Indenture (the “Base Indenture”), dated as of December 2, 2020, between the Company and the
Trustee, as amended by the Supplemental Indenture (the “Supplemental Indenture” and, together with the
Base Indenture, the “Indenture”), dated as of December 2, 2020, among the Company, 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 any provision of this Note conflicts with
the express provisions of the Base Indenture, the provisions of this Note shall govern and be controlling, and to the extent
any provision of this Note conflicts with the express provisions of the Supplemental Indenture, the provisions of the
Supplemental Indenture shall govern and be controlling. The Company shall be entitled to issue Additional Notes pursuant to
Section 2.05 of the Supplemental Indenture. The Notes are unsecured obligations of the Company.

SPECIAL MANDATORY REDEMPTION.

 

If (i) the
Acquisition has not been completed on or prior to 5:00 p.m. (Eastern Time) on July 24, 2021 (or, to the extent such date
is automatically extended pursuant to the terms of the Purchase Agreement, on or before October 24, 2021 or January 24,

Event”), the Company will be required to redeem (the “Special Mandatory Redemption”), within 30 days
of the Acquisition Triggering Event, all of the Notes, at a redemption price equal to 100% of the principal amount thereof, plus
accrued and unpaid interest to, but not including, the redemption date.

 

Upon the
occurrence of an Acquisition Triggering Event, the Company will promptly (but in no event later than five Business Days following
such Acquisition Triggering Event) notify the Holders of the Notes, by mail (or electronic delivery) of such event and set forth
the procedures governing the Special Mandatory Redemption, as described in Section 3.08 of the Supplemental Indenture.

 

(7) MANDATORY
REDEMPTION. Except as set forth under Section 6 above, the Company is not required to make mandatory redemption or
sinking fund payments with respect to the Notes.

 

(8)
REPURCHASE AT THE OPTION OF HOLDER. Upon the occurrence of a Change of Control Triggering Event, the Company will make an
offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an
integral multiple of $1,000 in excess of $2,000) 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
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. Within 30 days following any Change of Control, the Company will mail (or deliver
electronically) a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the
Indenture.

 

(9) NOTICE
OF REDEMPTION. At least 10 days but not more than 60 days before a redemption date, the Company shall mail or cause to be
mailed, by first class mail, or deliver electronically, a notice of redemption to each Holder whose Notes are to be redeemed
at its registered address, except that redemption notices may be mailed or delivered 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 Supplemental
Indenture pursuant to Articles 8 or 11 thereof. Notes and portions of Notes selected will be in 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 or purchased, the
entire outstanding amount of Notes held by such Holder shall be redeemed or purchased.

registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer

Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company
may require a Holder to pay any taxes and fees required by law or permitted by the Supplemental Indenture. The Company 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 Company 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.

(11) PERSONS

Holders have rights under the Indenture.

 

(12)
AMENDMENT, SUPPLEMENT AND WAIVER. The Base
Indenture may be amended as provided therein. Subject to certain exceptions, the Supplemental Indenture, the Notes or the
Subsidiary 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 Supplemental Indenture or the Notes or the Subsidiary
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 of Notes, the
Supplemental Indenture, the Notes or the Subsidiary Guarantees may be amended or supplemented (i) to cure any ambiguity,
mistake, defect or inconsistency, (ii) to provide for uncertificated Notes in addition to or in place of certificated
Notes (provided that such uncertificated Notes are issued in registered form for U.S. tax purposes), (iii) to provide
for the assumption of the Company’s Obligations to Holders of the Notes in the case of a merger or consolidation or
sale of all or substantially all of the Company’s assets pursuant to Article 5 of the Supplemental Indenture,
(iv) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does
not adversely affect the legal rights under the Supplemental Indenture of any such Holder, (v) [reserved], (vi) to
conform the text of the Supplemental Indenture or the Notes to any provision of the “Description of the Notes”
section of the Company’s Offering Memorandum, (vii) to evidence and provide for the acceptance and appointment
under the Supplemental Indenture of a successor trustee pursuant to the requirements thereof, (viii) to provide for the

(13) DEFAULTS
AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on, the Notes;
(ii) default in the payment when due of the principal of, or premium on, if any, the Notes; (iii) failure by the
Company or any Guarantor for 60 days after written notice to the Company by the Trustee or the Holders of at least 30% in
aggregate principal amount of the Notes then outstanding to comply with any of the agreements in the Supplemental Indenture
(other than a default referred to in clause (i) or (ii) of Section 6.01 of the Indenture); (iv) default
under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any Guarantor (or the payment of which is Guaranteed by the Company or any
Guarantor), whether such Indebtedness or Guarantee now exists, or is created after the date of the Supplemental Indenture, if
that default: (A) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior
to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment
Default”); or (B) results in the acceleration of such Indebtedness prior to its express maturity, and, in each
case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under

(14) TRUSTEE
DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were
not the Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict
within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights
and duties. The Trustee is also subject to and entitled to the benefits of Article 7 of the Base Indenture.

Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each

Capitalized terms used herein have the meanings
assigned to them in the Supplemental Indenture referred to below unless otherwise indicated.

 

(1)        INTEREST.
NRG Energy, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount
of this Note at 3.625% per annum from December 2, 2020 until maturity. The Company shall pay interest semi-annually in arrears
on February 15 and August 15 of each year, or if any such day is not a Business Day, on the next succeeding Business
Day (each, an “Interest Payment Date”). Interest on this Note 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 there is no existing
Default in the payment of interest, and 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; provided,
further, that the first Interest Payment Date shall be August 15, 2021. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

 

(2)        METHOD
OF PAYMENT. The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders
of Notes at the close of business on the February 1 and August 1 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 Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest
at the office or agency of the Paying Agent and Registrar within the City and State of New York, or, at the option of the Company,
payment of interest 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, if any, and
interest on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company
or the Paying Agent. Such payment shall 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, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent
and Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Notes. The Company
or any of its Subsidiaries may act as Paying Agent or Registrar.

 

(4)        INDENTURE.
This Note is one of a duly authenticated series of securities of the Company issued and to be issued in one or more series
under an Indenture (the “Base Indenture”), dated as of December 2, 2020, between the Company and the Trustee,
as amended by the Supplemental Indenture (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”),
dated as of December 2, 2020, among the Company, 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 any provision of this Note conflicts with the express provisions of the Base Indenture, the provisions of this Note
shall govern and be controlling, and to the extent any provision of this Note conflicts with the express provisions of the Supplemental
Indenture, the provisions of the Supplemental Indenture shall govern and be controlling. The Company shall be entitled to issue
Additional Notes pursuant to Section 2.05 of the Supplemental Indenture. The Notes are unsecured obligations of the Company.

PARTIAL MANDATORY REDEMPTION.

 

If (i) the
Acquisition has not been completed on or prior to 5:00 p.m. (Eastern Time) on July 24, 2021 (or, to the extent such date
is automatically extended pursuant to the terms of the Purchase Agreement, on or before October 24, 2021 or January 24,

repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to 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. Within 30 days following
any Change of Control, the Company will mail (or deliver electronically) a notice to each Holder setting forth the procedures governing

not the Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict
within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights
and duties. The Trustee is also subject to and entitled to the benefits of Article 7 of the Base Indenture.

redemption of Senior Notes held by the Trust and any delivery of Senior Notes by the Trust to NRG upon NRG’s exercise of
the Repurchase Right shall be effected by decreasing the principal amount of the Initial Note Certificate and recording such decrease
in the Security Register.

 

Section 2.2            Repurchase
Right.

 

(a)            Subject
to Section 2.2(b), NRG shall have the right to repurchase, on one or more occasions, Senior Notes then outstanding and held
by the Trust, in whole or in part, at any time in exchange for Eligible Treasury Assets that entitle the Trust to receive, on each
subsequent Distribution Date through and including the P-Caps Final Distribution Date, payments of principal and interest that
are in the same amounts as the Trust would have received on each such Distribution Date on the Eligible Treasury Assets that it
delivered to NRG, or to the Collateral Agent, as the case may be, upon the exercise of the Issuance Right in respect of the Senior
Notes to be so repurchased (the “Repurchase Price”). The repurchase right described in this Section 2.2(a) is
referred to herein as a “Repurchase Right” and any such repurchase is referred to herein as a “Repurchase”.

 

    11

     

    

 

(b)            The
Repurchase Right shall terminate upon the earliest to occur of (i) an Automatic Exercise Event, (ii) a Mandatory Exercise
Event pursuant to which the Available Amount is reduced to zero, or (iii) NRG’s delivery of a notice substantially in
a form of Annex B to the Trust and the Notes Trustee irrevocably waiving its right to exercise the Repurchase Right. NRG
may not effect a Repurchase of any Senior Notes for which NRG has delivered a notice of redemption pursuant to the Notes Indenture.

 

(c)            NRG
may exercise the Repurchase Right by delivering to the Trust and the Notes Trustee a notice substantially in the form of Annex
C, which notice shall specify the settlement date (the “Repurchase Settlement Date”), which shall be a Business
Day that is prior to the Trust Dissolution Date and at least three Business Days after NRG delivers such notice. On the Repurchase
Settlement Date, NRG shall deliver the Repurchase Price to the Trust against delivery of the Senior Notes by the Trust to NRG or
its designee. Each of NRG and the Trust hereby covenants and agrees that its delivery of the Repurchase Price or the Senior Notes,
respectively, pursuant to this Section 2.2 shall be made free and clear of any adverse claims, together with all transfer
and registration documents (or all notices, instructions or other communications) as are necessary to convey title to the Repurchase
Price or the Senior Notes to the Trust or NRG (or its designee), as the case may be and cause them to be a protected purchaser
(within the meaning of the New York Uniform Commercial Code) of the Repurchase Price or the Senior Notes, as the case may be.

 

Section 2.3            Termination
of Facility Agreement. The Issuance Right, the Repurchase Right and this Agreement shall terminate on the Trust
Dissolution Date, except with respect to obligations that have accrued hereunder prior to such date.

 

Section 2.4            Consolidated
Net Worth.

 

(a)            Consolidated
Net Worth. No later than five Business Days after each date on which NRG’s annual or quarterly financial statements are
required to be filed on Form 10-K or Form 10-Q with the SEC, including without limitation any applicable extensions thereof,
or if NRG is not required to file such financial statements with the SEC, the date on which NRG would be required to file such
financial statements if NRG continued to be subject to SEC filing requirements, NRG shall notify the Trust of its Consolidated
Net Worth as of the last day of the immediately preceding fiscal year or quarter, as the case may be, and state whether or not
a Mandatory Exercise Event has occurred. Such notice shall briefly describe any Reorganization or Accounting Change resulting in
a change in the Minimum Threshold pursuant to clauses (b), (c) and (d) of this Section since the later of (i) the
date of this Agreement or (ii) the most recent such notice and specify (A) the adjustment to the Minimum Threshold caused
by such Reorganization or Accounting Change, including the calculation of such adjustment, and (B) the effective date of such
adjustment.

 

    12

     

    

 

(b)            Reorganizations.
In the event of a Reorganization of NRG that would result in a change in its Consolidated Net Worth, after giving effect to such
Reorganization, of 15% or more of its Consolidated Net Worth immediately prior to such Reorganization, the Minimum Threshold shall
be adjusted by multiplying the Minimum Threshold applicable immediately prior to such Reorganization by a fraction, the numerator
of which is the Consolidated Net Worth after giving effect to such Reorganization, and the denominator of which is the Consolidated
Net Worth immediately prior to the Reorganization.

 

(c)           Change
of Accounting Policies. If at any time an Accounting Change would affect the computation of Consolidated Net Worth resulting
in a change in the Consolidated Net Worth, after giving effect to such Accounting Change, of 15% or more of the Consolidated Net
Worth immediately prior to such Accounting Change, the Minimum Threshold shall be adjusted by multiplying the Minimum Threshold
applicable immediately prior to the Accounting Change by a fraction, the numerator of which is the Consolidated Net Worth after
giving effect to the Accounting Change, and the denominator of which is the Consolidated Net Worth immediately prior to the Accounting
Change.

 

(d)           Calculation
of the Consolidated Net Worth. For purposes of this Section 2.4, the Consolidated Net Worth immediately prior to a Reorganization
or an Accounting Change shall be calculated based on the most recent annual or quarterly consolidated financial statements of NRG
that are available at the time of determination of such Consolidated Net Worth. NRG shall report any changes in the Minimum Threshold,
the basis for such change and the calculation thereof in a notice to the Trust.

 

Section 2.5            Exercisability
of the Issuance Right. The Issuance Right shall be exercisable in accordance with Section 2.1 notwithstanding
any failure to pay any amount due under this Agreement, and no such failure shall constitute a breach of or a default under this
Agreement unless, by the end of the 30th day following the applicable Distribution Date on which amounts are due from NRG to the
Trust, such failure has not been remedied (whether (i) by NRG paying the unpaid amount to the Trust or (ii) by NRG delivering
an Issuance Notice with respect to the entire Available Amount, for settlement prior to such 30th day, and such amounts being
set-off against the Notes Purchase Price in respect thereof (with the Eligible Treasury Assets included in the Notes Purchase
Price being valued for the purpose of such set-off based on the proceeds received therefor by the Trust)).

 

Section 2.6           Mandatory
Exercise Events. NRG shall give prompt written notice to the Trust of the occurrence of any Mandatory Exercise Event.

 

Section 2.7           Senior
Notes Issuance Capacity. NRG shall ensure at all times that the issuance of an aggregate principal amount of the Senior
Notes in an amount up to the Available Amount would not result in a breach or violation of, or constitute a default under, any
material agreement or instrument to which NRG is a party or by which NRG is bound (such provision, the “Senior Notes
Issuance Capacity Covenant”).

Article III

Exercise
of the Issuance Right

 

Section 3.1            Exercise
of the Issuance Right by NRG. The Issuance Right shall be exercisable upon delivery by NRG of an Issuance Notice to
the Trust and the Notes Trustee. The Issuance Notice shall specify (i) whether such exercise is a Mandatory Exercise, (ii) the
Settlement Date, which shall be a Business Day that is on or prior to the Trust Dissolution Date and at least two Business Days
after the date such notice is received by the Trust and the Notes Trustee, and if NRG is making a Cash Settlement Election, at
least 10 days but not more than 60 days following the date such notice is received by the Trust and the Notes Trustee; provided
that in the case of a Mandatory Exercise, the Settlement Date shall be the second Business Day after the date of receipt,
(iii) whether the Settlement Date is the Trust Dissolution Date, (iv) the principal amount of Senior Notes with respect
to which NRG is exercising the Issuance Right (the “Designated Amount”), which shall be an integral multiple
of $50,000,000 or a portion thereof, when the Available Amount is less than $50,000,000 at the time the Issuance Right is exercised,
or, in the case of a Mandatory Exercise, the entire Available Amount (in respect of a Mandatory Exercise Event occurring under
paragraphs (1), (2), (3), (4), (5) or (8) of the definition of “Mandatory Exercise Event”), the Collateral
Enforcement Amount (in respect of a Mandatory Exercise Event occurring under paragraph (6) of the definition of “Mandatory
Exercise Event”) or the Change of Control Offer Issuance Amount (in respect of a Mandatory Exercise Event occurring under
paragraph (7) of the definition of “Mandatory Exercise Event”)), (v) in the case of a Voluntary Exercise
or Mandatory Exercise, the principal amount of Senior Notes, if any, as to which NRG has made a Cash Settlement Election, (vi) in
the case of any Mandatory Exercise Event constituting a Collateral Enforcement Event, the amount of Eligible Treasury Assets that
have been withdrawn by the Collateral Agent from the Trust Collateral Account (the “Removed Collateral Amount”),
(vii) the remaining Available Amount, immediately after giving effect to the exercise of the Issuance Right pursuant to the
applicable Issuance Notice and (viii) whether all or any portion of the Notes Purchase Price will be retained as Retained
Eligible Treasury Assets. On the Settlement Date, (x) the Notes Trustee shall deliver the Designated Amount of the Senior
Notes or (y) with respect to any Senior Notes as to which NRG has made a Cash Settlement Election, NRG shall deliver the
Cash Settlement Amount to the Trust against delivery of the Notes Purchase Price by the Trust to NRG. Subject to Section 3.3(e),
upon the occurrence of a Mandatory Exercise Event, the Eligible Treasury Assets will be delivered to NRG by the Trust. Any Eligible
Treasury Assets delivered to NRG by the Trust pursuant to this Agreement will, subject to Section 3.3(e), (i) prior
to the termination of the LC Agreement, at NRG’s written instruction, either (x) be credited to the NRG Collateral
Account, which has been pledged in favor of the Collateral Agreement in accordance with the terms of the LC Agreement, or (y) with
respect to any Mandatory Exercise or Automatic Exercise, continue to be held by the Trust as Retained Eligible Treasury Assets,
and (ii) at any time after the termination of the LC Agreement, be delivered or credited to such account of NRG as NRG may
specify in a written notice to the Trust. In addition, to the extent that the Aggregate Collateral Amount exceeds the Minimum
Collateral Base at any time, upon written request of NRG, any such excess amount, as certified by NRG, shall be released from
any Lien created under the Pledge Agreement and NRG shall be permitted to withdraw such excess funds from the NRG Collateral Account,
and shall be permitted to withdraw such excess assets from the Trust Collateral Account in connection with any permitted exercise
of the Issuance Right under this Agreement , in accordance with Section 5(a) of the LC Agreement. This Agreement will
terminate on the Trust Dissolution Date, except with respect to obligations that have already accrued thereunder prior to the
Trust Dissolution Date.

 

    14

     

    

 

Section 3.2            Automatic
Exercise of the Issuance Right.

 

(a)            The
Trust shall deliver a notice substantially in the form of Annex D (such notice, an “Automatic Exercise Notice”)
to the Notes Trustee and NRG within two Business Days after obtaining actual knowledge of any Automatic Exercise Event that is
not a Bankruptcy Event, and the Settlement Date of such Automatic Exercise shall be the second Business Day after the date such
notice is received by the Notes Trustee, provided that if the Notes Trustee receives notice that a Bankruptcy Event with
respect to NRG has occurred before such Settlement Date, the Settlement Date shall be determined pursuant to Section 3.2(b).

 

(b)            NRG
shall deliver an Automatic Exercise Notice to the Trust and the Notes Trustee promptly upon becoming aware of any Bankruptcy Event
with respect to NRG and provide the Notes Trustee and the Trust with either an order of the court administering its bankruptcy,
liquidation or similar proceeding authorizing the issuance and sale of the Senior Notes to the Trust or an opinion of counsel that
the Senior Notes may be issued and sold to the Trust without obtaining any such order. The Settlement Date of such Automatic Exercise
shall be the second Business Day after such order or opinion of counsel is received by the Trust and the Notes Trustee or, if later,
the date required by such order.

 

(c)            On
the Settlement Date of an Automatic Exercise, the Notes Trustee shall deliver the entire Available Amount of the Senior Notes to
or upon the order of the Trust against delivery of the Notes Purchase Price by the Trust to NRG. Subject to Section 3.3(e),
upon the Settlement Date of an Automatic Exercise Event, the Eligible Treasury Assets will be delivered to NRG by the Trust. Any
Eligible Treasury Assets delivered to NRG by the Trust pursuant to this Agreement will be credited (i) prior to the termination
of the LC Agreement, to the NRG Collateral Account, which has been pledged in favor of the Collateral Agent in accordance with
the terms of the LC Agreement and (ii) at any time after the termination of the LC Agreement, to such account of NRG as NRG
may specify in a written notice to the Trust.

 

Section 3.3            Settlement
and Delivery.

 

(a)            Delivery
of the Senior Notes (or the Cash Settlement Amount, in respect of any Senior Notes as to which NRG has made a Cash Settlement Election)
and the Notes Purchase Price, in respect of any exercise of the Issuance Right shall take place prior to 3:00 p.m. on the
applicable Settlement Date. Unless otherwise changed by a prior written notice to the Trust by NRG (including, without limitation,
an Issuance Notice), on the applicable Settlement Date, subject to the receipt of the Senior Notes (or such Cash Settlement Amount),
the Notes Purchase Price shall be delivered to or upon the order of NRG according to the delivery instructions provided by NRG.
For the avoidance of doubt, any delay in delivery of any Senior Notes or Cash Settlement Amount or the Notes Purchase Price shall
not extinguish the rights of NRG or the Trust to receive the Notes Purchase Price or any Cash Settlement Amount or Senior Notes,
as the case may be, following the exercise of the Issuance Right.

 

    15

     

    

 

(b)            Payment
of the Notes Purchase Price shall be subject to set-off against any amounts due and unpaid by NRG to the Trust on the applicable
Settlement Date pursuant to this Agreement, the Trust Declaration or the Trust Expense Reimbursement Agreement and such setoff
shall be deemed to satisfy the Trust’s obligation to pay the Notes Purchase Price with respect to such set-off amounts (with
the Eligible Treasury Assets included in the Notes Purchase Price being valued for the purpose of such set-off based on the proceeds
received therefor by the Trust). Except as set forth in the immediately preceding sentence, payment of the Notes Purchase Price
by the Trust shall be made as provided in this Article III without setoff, claim, recoupment, deduction or counterclaim. For
the avoidance of doubt, the delivery of Eligible Treasury Assets to the Collateral Agent in connection with a Collateral Enforcement
Event shall constitute payment of the relevant portion of the Notes Purchase Price by the Trust for the issuance of Senior Notes
in connection with the related Mandatory Exercise.

 

(c)            Each
of NRG and the Trust hereby covenants and agrees that its delivery of the Senior Notes or the Notes Purchase Price, respectively,
pursuant to this Article III shall be made free and clear of any adverse claims (other than (i) the claims of the Collateral
Agent on the Note Purchase Price delivered to the NRG Collateral Account or (ii) that arise as a result of the actions of,
or claims against, another party hereto), together with all transfer and registration documents (or all notices, instructions or
other communications) as are necessary to convey title to the Senior Notes or the Notes Purchase Price to the Trust or NRG (or
its nominee), as the case may be and cause them to be a protected purchaser (within the meaning of the New York Uniform Commercial
Code) of the Senior Notes or the Notes Purchase Price, as the case may be. Regardless of when they are issued and sold to the Trust,
and whether they are issued and sold to the Trust pursuant to one exercise or several exercises, all Senior Notes issued shall
consist of a single series of securities under the Notes Indenture.

 

(d)            Prior
to the termination of the LC Agreement, following any Mandatory Exercise or Automatic Exercise of the Issuance Right, in lieu of
receiving the Eligible Treasury Assets from the Trust, NRG has the right to require the Trust to continue to hold such Eligible
Treasury Assets subject to the terms of the Pledge Agreement as Retained Eligible Treasury Assets. However, the Holders of the
Trust Securities will have no interest in and no rights to receive delivery of any Retained Eligible Treasury Assets or proceeds
thereof.

 

(e)            Notwithstanding
anything to the contrary, prior to termination of the LC Agreement, Eligible Treasury Assets that are pledged to the Collateral
Agent pursuant to the Pledge Agreement shall only be delivered to NRG by the Trust if, upon the delivery of such Eligible Treasury
Assets to NRG (i) such Eligible Treasury Assets will continue to be pledged to the Collateral Agent pursuant to the Pledge
Agreement and (ii) no default would exist or result under the LC Agreement or the Pledge Agreement from the delivery of such
Eligible Treasury Assets (any Eligible Treasury Assets retained by the Trust after the exercise of the Issuance Right pursuant
to such limitation, the “Blocked Eligible Treasury Assets”). The Trust and the Trustee may conclusively rely
on the statements of NRG in any Issuance Notice or any Mandatory Exercise Notice as to whether any Eligible Treasury Assets are
Retained Eligible Treasury Assets.

 

    16

     

    

 

Article IV

Facility
Fee and Purchase of Eligible Treasury Assets

 

Section 4.1            Facility
Fee. In consideration of the Trust’s agreement to purchase the Senior Notes upon the exercise of the Issuance
Right in accordance with the terms of this Agreement, NRG shall pay to the Trust, by wire transfer in immediately available funds,
by 11:00 a.m. on each Distribution Date in arrears in respect of the Distribution Period ending on such Distribution Date,
a premium (the “Facility Fee”) in an amount equal to 1.65% per annum applied to the Maximum Amount minus
the aggregate principal amount of Senior Notes then outstanding and held by the Trust as of the close of business on the Business
Day immediately preceding such Distribution Date, as applicable, calculated on a 30/360 Basis.

 

Section 4.2           Special
Facility Fee. In the event (x) the Trust has not received all payments due on any Distribution Date with respect
to the Eligible Treasury Assets (other than Retained Eligible Treasury Assets) and NRG has not paid for all Defaulted Eligible
Treasury Assets required to be purchased at their face amount from the Trust pursuant to Section 4.3
by 5:00 p.m. on such Distribution Date or (y) NRG has failed to pay any amount
due under this Agreement, the Trust Expense Reimbursement Agreement or the Senior Notes, by 5:00 p.m. on any Distribution
Date (such amounts in clauses (x) or (y) above, the “Overdue Amounts”), NRG shall pay to the Trust,
by wire transfer in immediately available funds, the Special Facility Fee no later than 11:00 a.m. on the earliest of (i) the
date on which the Trust is required to distribute any Overdue Amount pursuant to Section 5.8(d) of the Trust Declaration,
(ii) the Settlement Date of the exercise of the entire Available Amount after such Distribution Date and (iii) the date
on which any Overdue Amount is paid in respect of any amounts payable on the Trust Dissolution Date (the “Special Facility
Fee Payment Date”).

 

Section 4.3           Purchase
of Defaulted Eligible Treasury Assets. NRG hereby agrees to purchase from the Trust on any Distribution Date any Defaulted
Eligible Treasury Assets (or the proceeds thereof) for an amount equal to their face amount by wire transfer in immediately available
funds.

 

Article V

Obligations
Absolute

 

Section 5.1           Obligations
Absolute. The Trust acknowledges that the obligations of the Trust undertaken under this Agreement are absolute, irrevocable
and unconditional irrespective of any circumstances whatsoever, including any defense otherwise available to the Trust, in equity
or at law, including the defense of fraud, any defense based on the failure of NRG to disclose any matter, whether or not material,
to the Trust or any other Person, and any defense of breach of warranty or misrepresentation, and irrespective of any other circumstance
that might otherwise constitute a legal or equitable discharge or defense under any and all circumstances whatsoever. The enforceability
and effectiveness of this Agreement and the liability of the Trust, and the rights, remedies, powers and privileges of NRG under
this Agreement shall not be affected, limited, reduced, discharged or terminated, and the Trust hereby expressly waives, to the
fullest extent permitted by applicable law, any defense now or in the future arising by reason of:

 

    17

     

    

 

(i)            the
illegality, invalidity or unenforceability of all or any part of the Trust Declaration;

 

(ii)           any
action taken, or omission to act, by NRG;

 

(iii)          any
change in the direct or indirect ownership or control of NRG or of any shares or ownership interests thereof; and

 

(iv)          any
other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of or for the Trust; provided
that, notwithstanding the provisions of this Section 5.1, the Trust shall have no further obligations hereunder after this
Agreement is terminated. The breach of any covenant, representation or warranty made in this Agreement by the Trust or NRG shall
not result in the termination of the Issuance Right or limit the rights of the Trust or NRG hereunder.

 

Other than as specifically set forth herein,
neither the Trust nor the Trustee shall be entitled to receive from NRG any certificate, opinion or other document in connection
with the exercise of the Issuance Right.

 

Section 5.2            No
Waiver. For the avoidance of doubt, so long as the Issuance Right has not terminated, no failure or delay by NRG in
exercising its rights hereunder shall operate as a waiver of its rights hereunder except as specifically provided in this Agreement.

Section 7.3          Amendments.
This Agreement may be amended by NRG and the Trust with the consent of at least a Majority of Holders, except that (x) the
unanimous consent of the Holders of the Trust Securities is required for any change in the payment terms in the definition of
 “Special Facility Fee”, Section 2.2, Article III or Article IV that would affect the timing or amount
