and are hereby expressly made, a part of the Indenture. The Notes may have notations, legends or endorsements required by law,
rules of or agreements with national securities exchanges to which the Company is subject. Each Note will be dated the date of
its authentication. The Notes will be issuable in minimum denominations of $2,000 in principal amount and integral multiples of
$1,000 in excess thereof.


 




    	12



    	 



    

(b)(i)Except as otherwise provided

(c)If the Company determines (upon the
advice of counsel and such other certifications and evidence as the Company may reasonably require) that a Note is eligible for
resale pursuant to Rule 144 under the Securities Act (or a successor rule) and that the Restricted Legend is no longer necessary
or appropriate in order to ensure that subsequent transfers of the Note (or a beneficial interest therein) are effected in compliance
with the Securities Act, the Company may instruct the Trustee to cancel the Note and issue to the Holder thereof (or to its transferee)
a new Note of like tenor and amount, registered in the name of the Holder thereof (or its transferee), that does not bear the Restricted
Legend, and the Trustee will comply with such instruction.


 


(d)By its acceptance of any Note bearing
the Restricted Legend (or any beneficial interest in such a Note), each Holder thereof and each owner of a beneficial interest
therein acknowledges the restrictions on transfer of such Note (and any such beneficial interest) set forth in this Indenture and
in the Restricted Legend and agrees that it will transfer such Note (and any such beneficial interest) only in accordance with
the Indenture and such legend.


 


SECTION 2.02.Execution and Authentication;
Additional Notes.  (a)An Officer shall execute the Notes for the Company by facsimile or manual signature in the
name and on behalf of the Company. If an Officer whose signature is on a Note no longer holds that office at the time the Note
is authenticated, the Note will still be valid.


 


(b)A Note will not be valid until the
Trustee manually signs the certificate of authentication on the Note, with the signature conclusive evidence that the Note has
been authenticated under the Indenture.


 


(c)At any time and from time to time after
the execution and delivery of the Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication.
The Trustee will authenticate and deliver


 


(i)Notes for original issue
in the aggregate principal amount not to exceed $405,000,000, and


 


(ii)Additional Notes from time
to time for original issue in aggregate principal amounts specified by the Company


 




    	13



    	 



    

after the following conditions have
been met:


 


(1)Receipt by the Trustee of an
Officers’ Certificate specifying


 


(A)the amount of Notes to be
authenticated and the date on which such Notes are to be authenticated,


 


(B)whether such Notes are to
be Initial Notes or Additional Notes,


 


(C)in the case of Additional
Notes, that the issuance of such Notes does not contravene any provision of Article 4 of the Indenture, and


 


(D)other information the Company
may determine to include or the Trustee may reasonably request (including, without limitation, statements per Section 10.04 herein).


 


(2)In the case of Additional Notes,
receipt by the Trustee of an Opinion of Counsel confirming that such Additional Notes are fungible with the Initial Notes for U.S.

reopening under Treasury Regulations section 1.1275-2(k) for U.S. federal income tax purposes.

the Trustee to authenticate such Notes.


 


(4)An Opinion of Counsel per Section
10.04 herein.


 


SECTION 2.03.Registrar, Paying
Agent and Authenticating Agent; Paying Agent to Hold Money in Trust. (a)The Company may appoint one or more Registrars
and one or more Paying Agents, in which case each reference in the Indenture to the Trustee in respect of the obligations of the
Trustee to be performed by that Agent will be deemed to be references to the Agent. The Company may act as Registrar or (except
for purposes of Article 8) Paying Agent. In each case the Company and the Trustee will enter into an appropriate agreement
with the Agent implementing the provisions of the Indenture relating to the obligations of the Trustee to be performed by the Agent
and the related rights. The Company initially appoints the Trustee as Registrar and Paying Agent.


 


(b)The Company will require each Paying
Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of the Holders or the
Trustee all money held by the Paying Agent for the payment of principal of and interest on the Notes and will promptly notify the
Trustee of any default by the Company in making any such payment. The Company at any time may require a Paying Agent to pay all
money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of
any payment default, upon written request to a Paying Agent, require the Paying


 




    	14



    	 



    

Agent to pay all money held by it
to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no further liability for the money
so paid over to the Trustee.


 


SECTION 2.04.Replacement Notes.
If a mutilated Note is surrendered to the Trustee or if a Holder claims that its Note has been lost, destroyed or wrongfully taken,
the Company will issue and the Trustee will authenticate a replacement Note of like tenor and principal amount and bearing a number
not contemporaneously outstanding. Every replacement Note is an additional obligation of the Company and entitled to the benefits
of the Indenture. If required by the Trustee or the Company, an indemnity must be furnished that is sufficient in the judgment
of both the Trustee and the Company to protect the Company and the Trustee from any loss they may suffer if a Note is replaced.
The Company may charge the Holder for the expenses of the Company and the Trustee in replacing a Note. In case the mutilated, lost,
destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay the
Note instead of issuing a replacement Note.


 


SECTION 2.05.Outstanding Notes.
(a)Notes outstanding at any time are all Notes that have been authenticated by the Trustee except for:


 


(i)Notes cancelled by the Trustee
or delivered to it for cancellation;


 


(ii)any Note which has been
replaced pursuant to Section 2.04 unless and until the Trustee and the Company receive proof satisfactory to them that the
replaced Note is held by a bona fide purchaser; and


 


(iii)on or after the maturity
date or any redemption date or date for purchase of the Notes pursuant to a Change of Control Offer, those Notes payable or to
be redeemed or purchased on that date for which the Trustee (or Paying Agent, other than the Company or an Affiliate of the Company)
holds money sufficient to pay all amounts then due.


 


(b)A Note does not cease to be outstanding
because the Company or one of its Affiliates holds the Note, provided that in determining whether the Holders of the requisite
principal amount of the outstanding Notes have given or taken any request, demand, authorization, direction, notice, consent, waiver
or other action hereunder, Notes owned by the Company or any Affiliate of the Company will be disregarded and deemed not to be
outstanding (it being understood that in determining whether the Trustee is protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other action, only Notes which a Responsible Officer of the Trustee actually
knows to be so owned will be so disregarded). Notes so owned which have been pledged in good faith may be regarded as outstanding
if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and
that the pledgee is not the Company or any Affiliate of the Company.


 


SECTION 2.06.Temporary Notes.
Until definitive Notes are ready for delivery, the Company may prepare and the Trustee will authenticate temporary Notes. Temporary
Notes will be substantially in the form of definitive Notes but may have insertions,


 




    	15



    	 



    

substitutions, omissions and other variations
determined to be appropriate by the Officer executing the temporary Notes, as evidenced by the execution of the temporary Notes.
If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation
of definitive Notes, the temporary Notes will be exchangeable for definitive Notes upon surrender of the temporary Notes at the
office or agency of the Company designated for the purpose pursuant to Section 4.02, without charge to the Holder. Upon surrender
for cancellation of any temporary Notes, the Company will execute and the Trustee will authenticate and deliver in exchange therefor
a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes will be entitled
to the same benefits under the Indenture as definitive Notes.


 


SECTION 2.07.Cancellation.
The Company at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously
authenticated hereunder which the Company has not issued and sold. Any Registrar or the Paying Agent will forward to the Trustee
any Notes surrendered to it for transfer, exchange or payment. The Trustee will cancel all Notes surrendered for transfer, exchange,
payment or cancellation and dispose of them in accordance with its normal procedures or the written instructions of the Company.
The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.


 


SECTION 2.08.CUSIP and CINS Numbers.
The Company in issuing the Notes may use “CUSIP” and “CINS” numbers for the Notes, and the Trustee will
use CUSIP numbers or CINS numbers in notices of redemption and in Change of Control Offers as a convenience to Holders, the notice
to state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in
any notice of redemption or Change of Control Offer. The Company will promptly notify the Trustee of any change in the CUSIP or
CINS numbers.


 


SECTION 2.09.Registration, Transfer
and Exchange. (a) The Notes will be issued in registered form only, without coupons, and except under the circumstances described
in subsections (b)(ii) or (b)(iv) of this Section 2.09, the Notes will be issued in global form only. The Company shall
cause the Trustee to maintain a register (the “Register”) of the Notes, for registering the record ownership
of Notes by the Holders thereof and transfers and exchanges of the Notes.


 


(b)(i)Each Global Note will be registered
in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.


 


(ii)Each Global Note will be
delivered to the Trustee as custodian for the Depositary. Transfers of a Global Note (but not a beneficial interest therein) will
be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except
(x) as set forth in Section 2.09(b)(iv) and (y) transfers of portions thereof in the form of Certificated Notes
may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to


 




    	16



    	 



    

the Trustee by or on behalf of the
Depositary in accordance with customary procedures of the Depositary and in compliance with this Section and Section 2.10.


 


(iii)Agent Members will have
no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary may be
treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global
Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise
authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent
Member) to take any action which a Holder is entitled to take under the Indenture or the Notes, and nothing herein will impair,
as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a
holder of any security.


 


(iv)If (A) the Depositary (x)
notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note or (y) has ceased to be a clearing
agency registered under the Exchange Act, and in each case a successor depositary is not appointed by the Company within 90 days
of that notice or becoming aware that the Depositary is no longer so registered or willing or able to act as a depositary, (B)
the Company determines not to have the Notes represented by a Global Note and provides written notice thereof to the Trustee; provided
that in no event shall a Temporary Offshore Global Note be exchanged for certificated Notes prior to the expiration of the distribution
compliance period and the receipt of any required Regulation S Certificate; or (C) an Event of Default shall have occurred and
be continuing with respect to the Notes, the Trustee will promptly exchange each beneficial interest in each Global Note for one
or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the name of the
owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon each Global Note will be deemed
canceled. If a Global Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange therefor will not
bear the Restricted Legend. If a Global Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor
will bear the Restricted Legend, provided that any Holder of any such Certificated Note issued in exchange for a beneficial
interest in a Temporary Offshore Global Note will have the right upon presentation to the Trustee of a duly completed Certificate
of Beneficial Ownership after the Restricted Period to exchange such Certificated Note for a Certificated Note of like tenor and
amount that does not bear the Restricted Legend, registered in the name of such Holder.


 


(c)Each Certificated Note issued pursuant
to subsection (b)(iv) will be registered in the name of the Holder thereof or its nominee.


 


(d)A Holder may transfer a Note (or a
beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes
of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee
or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.10. The
Trustee will promptly register any


 




    	17



    	 



    

transfer or exchange that meets the
requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that:


 


(i)no transfer or exchange will
be effective until it is registered in such register and


 


(ii)the Trustee will not be
required (x) to issue, register the transfer of or exchange any Note for a period of 15 days before a selection of Notes
to be redeemed or purchased pursuant to a Change of Control Offer, (y) to register the transfer of or exchange any Note so
selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion
of any Note not being redeemed or purchased, or (z) if a redemption or a purchase pursuant to a Change of Control Offer is
to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange
any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer,
the Company, the Trustee and their agents will treat the Person in whose name any Note is registered as the owner and Holder thereof
for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary.


 


From time to time the Company will execute
and the Trustee will authenticate additional Notes as necessary in order to permit the registration of a transfer or exchange in
accordance with this Section.


 


No service charge will be imposed in connection
with any transfer or exchange of any Note, but the Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable
upon exchange pursuant to subsection (b)(iv)).


 


(e)(i)Global Note to Global
Note. If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global
Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal
to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global
Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest
in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest
in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer
and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long
as it remains such an interest.


 


(ii)Certificated Note to Certificated
Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel
the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations
having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case
of a transfer) or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee
or Holder, as applicable, and (z) if such transfer


 




    	18



    	 



    

or exchange involves less than the
entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more Certificated Notes in authorized
denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated
Note, registered in the name of the Holder thereof.


 


SECTION 2.10.Restrictions on Transfer
and Exchange. (a) The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with
this Section and Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and
procedures of the Depositary. The Trustee shall refuse to register any requested transfer or exchange that does not comply with

with the Securities Act and any applicable securities laws of any state of the United States; provided that if the requested
transfer or exchange is made by the Holder of a Certificated Note that does not bear the Restricted Legend, then no certification
is required. In the event that (1) the requested transfer or exchange takes place after the Restricted Period and a duly completed
Regulation S Certificate is delivered to the Trustee or (2) a Certificated Note that does not bear the Restricted Legend is
surrendered for transfer or exchange, upon transfer or exchange the Trustee will deliver a Certificated Note that does not bear
the Restricted Legend.


 


(iv)The Person requesting the
transfer or exchange must deliver or cause to be delivered to the Trustee a duly completed Rule 144A Certificate.


 




    	19

with any transfer or exchange of any Note (or a beneficial interest therein) after such Note (i) is eligible for resale pursuant
to Rule 144 under the Securities Act (or a successor provision); provided that the Company has provided the Trustee
with an Officer’s Certificate to that effect, and the Company may require from any Person requesting a transfer or exchange
in reliance upon this clause an opinion of counsel and any other reasonable certifications and evidence in order to support such
certificate; or


 


(ii)sold pursuant to an effective
registration statement.


 


Any Certificated Note delivered
in reliance upon this paragraph will not bear the Restricted Legend.


 


(d)The Trustee will retain copies of all
certificates, opinions and other documents received in connection with the transfer or exchange of a Note (or a beneficial interest
therein), and the Company will have the right to inspect and make copies thereof at any reasonable time upon reasonable prior written
notice to the Trustee.


 


SECTION 2.11.Temporary Offshore
Global Notes. (a)Each Note originally sold by the Initial Purchasers in reliance upon Regulation S will be evidenced
by one or more Offshore Global Notes that bear the Temporary Offshore Global Note Legend.


 


(b)An owner of a beneficial interest in

accept) a duly completed Certificate of Beneficial Ownership at any time after the Restricted Period (it being understood that
the Trustee will not accept any such certificate during the Restricted Period). Promptly after acceptance of a Certificate of Beneficial
Ownership with respect to such a beneficial interest, the Trustee will cause such beneficial interest to be exchanged for an equivalent
beneficial interest in a Permanent Offshore Global Note, and will (x) permanently reduce the principal amount of such Temporary
Offshore Global Note by the amount of such beneficial interest and (y) increase the principal amount of such Permanent Offshore
Global Note by the amount of such beneficial interest.


 


(c)Notwithstanding anything to the contrary
contained herein, beneficial interests in a Temporary Offshore Global Note may be held through the Depositary only through Euroclear
and Clearstream and their respective direct and indirect participants.

with such request and will (x) permanently reduce the principal amount of such Temporary Offshore Global Note by the amount
of such beneficial interest and (y) increase the principal amount of such Permanent Offshore Global Note by the amount of
such beneficial interest.

(ii)the sum of the present values
of the remaining scheduled payments of principal of and interest on the Notes being redeemed (excluding interest accrued to the
date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day
months) at a discount rate equal to the Treasury Rate plus 30 basis points;


 


plus, for (i) or (ii) above, whichever is
applicable, accrued interest on such Notes to, but not including, the date of redemption.


 


(b)Under the procedures set forth above,
the Redemption Price payable upon the optional redemption prior to June 15, 2020 of any Notes called for redemption shall be determined
by calculating the present value at that time of each remaining payment of principal of or interest on such Notes and then totaling
those present values. If the sum of those present values is equal to or less than 100% of the principal amount of the Notes called
for redemption, the Redemption Price of such Notes shall be 100% of its principal amount (redemption at par). If the sum of the
present values is greater than 100% of the principal amount of the Notes called for redemption, the Redemption Price of such Notes
shall be that greater amount (redemption at a premium). In no event may any Notes be redeemed optionally at less than 100% of their
principal amount. The Redemption Price will be calculated by the Quotation Agent and the Company, the Trustee and any Paying Agent
will be entitled to rely on such calculation.


 


(c)At any time on or after June 15, 2020,
the Notes will be redeemable in whole or in part, at the election of the Company, at a Redemption Price equal to 100% of the principal
amount of the Notes to be redeemed plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the date
of redemption


 


SECTION 3.02.Method and Effect
of Redemption. (a) If the Company elects to redeem any Notes, it must notify the Trustee of the redemption date and the principal
amount of Notes to be redeemed by delivering an Officers’ Certificate to the Trustee at least 15 days prior to the date
of the mailing of the notice (unless a shorter period is satisfactory to the Trustee in the sole determination of the Trustee).
If fewer than all of the Notes are being redeemed, the Officers’ Certificate must also specify a record date not less than
15 days after the date of the notice of redemption is given to the Trustee, and the Trustee will select the Notes to be redeemed
pro rata, by lot or by any other method the Trustee in its sole discretion deems appropriate, in denominations of $1,000 principal
amount and multiples thereof. The Trustee will notify the


 




    	21



    	 



    

Company promptly of the Notes or portions
of Notes to be called for redemption. Notice of redemption must be sent by the Company or at the Company’s request (the Company
to provide or cause to be provided to the Trustee such information to be included in such notice five (5) days prior to such notice
being sent to Holders, unless a shorter period is satisfactory to the Trustee, in the sole determination of the Trustee), by the
Trustee in the name and at the expense of the Company, to Holders whose Notes are to be redeemed at least 30 days but not
more than 60 days before the redemption date.


 


(b)The notice of redemption will identify
the Notes to be redeemed and will include or state the following:


 


(i)the redemption date;


 


(ii)the Redemption Price, including
the portion thereof representing any accrued interest;


 


(iii)the place or places where
Notes are to be surrendered for redemption;


 


(iv)Notes called for redemption
must be so surrendered in order to collect the Redemption Price;


 


(v)on the redemption date the
Redemption Price will become due and payable on Notes called for redemption, and interest on Notes called for redemption will cease
to accrue on and after the redemption date;


 


(vi)if any Note is redeemed
in part, on and after the redemption date, upon surrender of such Note, new Notes equal in principal amount to the unredeemed portion
will be issued; and


 


(vii)if any Note contains a
CUSIP or CINS number, no representation is being made as to the correctness of the CUSIP or CINS number either as printed on the
Notes or as contained in the notice of redemption and that the Holder should rely only on the other identification numbers printed
on the Notes.


 


(c)Once notice of redemption is sent to
the Holders, Notes called for redemption become due and payable at the Redemption Price on the redemption date, and upon surrender
of the Notes called for redemption, the Company shall redeem such Notes at the Redemption Price. Commencing on the redemption date,
Notes redeemed will cease to accrue interest. Upon surrender of any Note redeemed in part, the Holder will receive a new Note equal
in principal amount to the unredeemed portion of the surrendered Note.


 


SECTION 3.03.Sinking Fund.
 No sinking fund is provided for the Notes.

in anticipation of the transaction, unless the Lien was created to secure or provide for the payment of any part of the purchase
price of that entity;


 


(B)any Lien on any property or
assets existing at the time of its acquisition and which is not created in anticipation of such acquisition, unless the Lien was
created to secure or provide for the payment of any part of the purchase price of such property or assets; and

all conditions and covenants under this Indenture (such compliance to be determined without regard to any period of grace or requirement
of notice provided under this Indenture) which certificate shall comply with the requirements of the Trust Indenture Act. The Company
shall also notify the Trustee of any Default or Event of Default under this Indenture, provided, however, that a

each case, with a copy to the Trustee), with the information with respect to the Company required to be delivered under Rule 144A(d)(4)
under the Securities Act to enable resales of the Notes to be made pursuant to Rule 144A. Delivery of such reports, information

    	27



    	 



    

the Trustee’s receipt of such

under the Change of Control provisions of the Notes by virtue of such conflicts.

entity organized under the laws of the United States of America, one of its States or the District of Columbia and expressly assumes
by supplemental indenture the Company’s obligations under the Notes and the Indenture, provided, however, that
in the event following a conveyance, transfer or lease of the Company’s consolidated properties and assets substantially
as an entirety or a conveyance, transfer or lease of all or substantially all of the Company’s consolidated electric generation
assets and operations, the Company continues to own, directly or indirectly, its consolidated electric transmission and distribution

    	29



    	 



    

exercise every right and power of, the Company

Article 6



Default and Remedies


 


SECTION 6.01.Events of Default.
An “Event of Default” occurs with respect to the Notes if:


 


(i)the Company defaults in the
payment of the principal of, or any premium on, any Note when the same becomes due and payable at maturity, upon acceleration,
redemption or required purchase or otherwise;


 


(ii)the Company defaults in
the payment of interest on any Note when the same becomes due and payable, and the default continues for a period of 30 days;


 


(iii)the Company defaults in
the performance of or breaches any other covenant or agreement of the Company in the Indenture or under the Notes and the default
or breach continues for a period of 30 consecutive days after written notice specifying the default is delivered to the Company
by the Trustee or to the Company and the Trustee by the Holders of 25% or more in aggregate principal amount of the Notes;


 


(iv)a default occurs in the
payment of the principal of any bond, debenture, note or other evidence of indebtedness, in each case for money borrowed, issued
by the Company, or in the payment of principal under any mortgage, indenture or instrument under which there may be issued or by
which there may be secured or evidenced any Indebtedness for Borrowed Money, of the Company or any Significant Subsidiary if such
Indebtedness for Borrowed Money is not Project Finance Debt and provides for recourse generally to the Company or any Significant
Subsidiary, which default for payment of principal is in an aggregate principal amount exceeding $40 million when such indebtedness
becomes due and payable (whether at maturity, upon redemption or acceleration or otherwise), if such default shall continue unremedied
or unwaived for more than 30 Business Days and the time for payment of such amount has not been expressly extended (until such
time as such payment default is remedied, cured or waived);


 


(v)a court having jurisdiction
enters a decree or order for: (i) relief in respect of the Company or any of its Significant Subsidiaries in an involuntary
case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect; (ii) appointment of a receiver,
liquidator, assignee, custodian, trustee, sequestrator, or similar official of the Company or any of its Significant Subsidiaries
or for all or substantially all of the property and assets of the Company or any of its Significant Subsidiaries; or (iii) the
winding up or liquidation of the affairs of the Company or any of its Significant Subsidiaries; and, in each case, such decree
or order shall remain unstayed and in effect for a period of 60 consecutive days;


 




    	30



    	 



    

(vi)the Company or any of its
Significant Subsidiaries: (i) commences a voluntary case under any applicable bankruptcy, insolvency, or other similar law
now or hereafter in effect, or consents to the entry of an order for relief in an involuntary case under any such law; (ii) consents
to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official
of the Company or any of its Significant Subsidiaries or for all or substantially all of the property and assets of the Company
or any of its Significant Subsidiaries; or (iii) effects any general assignment for the benefit of creditors (an event of
default specified in clause (v) or (vi) a “Bankruptcy Default”); or


 


(vii)the Collateral Agent fails
to have a perfected security interest in the Pledged Stock of IPL for a period of 10 days.


 


SECTION 6.02.Acceleration.
 (a) If an Event of Default, other than a Bankruptcy Default with respect to the Company, occurs with respect to the Notes
and is continuing under the Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, by written notice to the Company (and to the Trustee if the notice is given by the Holders), may, and the Trustee
at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest on the outstanding Notes
to be immediately due and payable. Upon a declaration of acceleration, such principal, premium, if any, and accrued interest will
become immediately due and payable. If a Bankruptcy Default occurs with respect to the Company, the principal of, premium, if any,
and accrued interest on the Notes then outstanding will become immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder.


 


(b)The Holders of a majority in principal
amount of the outstanding Notes by written notice to the Company and to the Trustee may waive all past defaults with respect to
the Notes and rescind and annul a declaration of acceleration with respect to the Notes and its consequences if:


 


(i)all existing Events of Default
applicable to the Notes, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become
due solely by the declaration of acceleration, have been cured or waived; and


 


(ii)the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction.


 


SECTION 6.03.Other Remedies.
If an Event of Default with respect to the Notes occurs and is continuing, the Trustee may pursue, in its own name or as trustee
of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if
any, and interest on the Notes or to enforce the performance of any provision of the Notes or the Indenture. The Trustee may maintain
a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. When the Trustee Incurs
expenses or renders services after the occurrence of an act of bankruptcy with respect to the Company, the expenses and the compensation
for such services are intended to constitute expenses of administration under any federal or state bankruptcy, insolvency, arrangement,
moratorium, reorganization or other debtor relief law.


 




    	31



    	 



    

SECTION 6.04.Waiver of Past Defaults.
Except as otherwise provided in Sections 6.02, 6.07 and 9.02, the Holders of a majority in principal amount of outstanding
Notes may, by notice to the Trustee, waive an existing Default with respect to the Notes and its consequences. Upon such waiver,
the Default with respect to the Notes will cease to exist, and any Event of Default arising therefrom will be deemed to have been
cured, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.


 


SECTION 6.05.Control by Majority.
 The Holders of at least a majority in aggregate principal amount of outstanding Notes may direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustee
in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of the Notes
not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such
direction received from Holders of the Notes.


 


SECTION 6.06.Limitation on Suits.
A Holder of the Notes may not institute any proceeding, judicial or otherwise, with respect to the Indenture or the Notes, or for
the appointment of a receiver or trustee, or for any other remedy under the Indenture or the Notes, unless:


 


(i)such Holder has previously

principal of, premium, if any, or interest on its Note on or after the stated maturities thereof, or to bring suit for the enforcement

SECTION 6.08.Collection Suit by
Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in clause (1) or
(2) of Section 6.01 occurs and


 




    	32



    	 



    

is continuing with respect to the Notes, the
Trustee may recover judgment in its own name and as trustee of an express trust for the whole amount of principal, premium, if
any, and accrued interest remaining unpaid on the Notes, together with interest on overdue principal and, to the lawful, overdue
installments of interest, in each case at the rate specified in the Notes, and such further amount as is sufficient to cover the
costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel and any other amounts due the Trustee hereunder.


 


SECTION 6.09.Trustee May File
Proofs of Claim. The Trustee may file 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 compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders allowed in any judicial proceedings relating
to the Company or its creditors or property, and is entitled and empowered to collect, receive and distribute any money, securities
or other property payable or deliverable upon conversion or exchange of the Notes or upon any such claims. Any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, if the Trustee consents 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 agent and counsel, and any other amounts due the Trustee hereunder. Nothing in the Indenture will be deemed to empower 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 thereof, 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, it shall payout the money in the following order:


 


First: to the Trustee for all
amounts due to the Trustee hereunder;


 


Second: to Holders of the Notes

on such Notes, ratably, without preference or priority of any kind of any Note over any other Note, according to the amounts due
and payable on such Notes for principal, premium, if any, and interest; and


 


Third: to the Company or as a
court of competent jurisdiction may direct in a final, non-appealable order.


 


The Trustee, upon written notice to the Company, may fix a record
date and payment date for any payment to Holders pursuant to this Section.


 


SECTION 6.11.Restoration of Rights
and Remedies.  If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under the Indenture
and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the
Holder, then, subject to any determination in the proceeding,


 




    	33



    	 



    

the Company, the Trustee and the Holders will
be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Company,
the Trustee and the Holders will continue as though no such proceeding had been instituted.


 


SECTION 6.12.Undertaking for Costs.
In any suit for the enforcement of any right or remedy under the Indenture or in any suit against the Trustee for any action taken
or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking
to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys fees and expenses, against
any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by a Holder to enforce payment of principal of or interest on
any Note on the respective due dates, or a suit by Holders of more than 10% in principal amount of the outstanding Notes.


 


SECTION 6.13.Rights and Remedies
Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under this Indenture is intended
to be exclusive of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative
and in addition to every other right and remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion
or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or exercise of any other
right or remedy.


 


SECTION 6.14.Delay or Omission
Not Waiver.  No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any
Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and
as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.


 


SECTION 6.15.Waiver of Stay, Extension
or Usury Laws. The Company covenants, to the extent that it may lawfully do so, that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law
or other law that would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or
interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants
or the performance of the Indenture. The Company hereby expressly waives, to the extent that it may lawfully do so, all benefit
or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.


 


Article 7



The Trustee


 


SECTION 7.01.General. 
(a) The duties and responsibilities of the Trustee are as provided by the Trust Indenture Act and as set forth herein. Whether
or not expressly so


 




    	34



    	 



    

provided, every provision of the Indenture
relating to the conduct or affecting the liability of or affording protection to the Trustee is subject to this Article.


 


(b)Except during the continuance of an
Event of Default, the Trustee needs to perform only those duties that are specifically set forth in the Indenture and no others,
and no implied covenants or obligations will be read into the Indenture against the Trustee. In the absence of bad faith on its
part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein,
upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of
any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee
shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need
not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). In case an Event of Default
has occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by the Indenture, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his
own affairs.


 


(c)No provision of the Indenture shall
be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful
misconduct, except that


 


(1)this Subsection shall not be
construed to limit the effect of Subsection (a) of this Section;


 


(2)the Trustee shall not be liable
for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent
in ascertaining the pertinent facts;


 


(3)the Trustee shall not be liable
with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of
a majority in principal amount of the Notes relating to the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the
Securities of such series; and


 


(4)no provision of this Indenture
shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it


 


SECTION 7.02.Certain Rights of
Trustee.  Subject to Trust Indenture Act Sections 315(a) through (d):


 


(i)In the absence of bad faith
on its part, the Trustee may conclusively rely, and will be protected in acting or refraining from acting, upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction,


 




    	35



    	 



    

consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented
by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but, in the case of any document
which is specifically required to be furnished to the Trustee pursuant to any provision hereof, the Trustee shall examine the document
to determine whether it conforms to the requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical
calculations or other facts stated therein). The Trustee, in its discretion, may make further inquiry or investigation into such
facts or matters as it sees fit and shall Incur no liability of any kind by reason of such inquiry or investigation.


 


(ii)Before the Trustee acts
or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel conforming to Section 10.05
and the Trustee will not be liable for any action it takes or omits to take in good faith in reliance on the certificate or opinion.


 


(iii)The Trustee may act through
its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care.


 


(iv)The Trustee will be under
no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the
Holders of the Notes, unless such Holders have offered to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities that might be Incurred by it in compliance with such request or direction.


 


(v)The Trustee will not be liable
for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers or for
any action it takes or omits to take in accordance with the direction of the Holders of the Notes in accordance with Section 6.05
relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any
trust or power conferred upon the Trustee, under the Indenture.

(vii)No provision of the Indenture
will require the Trustee to expend or risk its own funds or otherwise Incur any financial liability in the performance of its duties
hereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability
or expense.


 


(viii)In no event shall the
Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but
not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.


 




    	36



    	 



    

(ix)The Trustee shall not be
deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof
or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office
of the Trustee, and such notice references the Securities and this Indenture.


 


(x)The rights, privileges, protections,
immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and
shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to
act hereunder.

liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized
or within the discretion or rights or powers conferred upon it by this Indenture.

SECTION 7.03.Individual Rights
of Trustee. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise
deal with the Company or its Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the same
with like rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b) and 311. For purposes of Trust Indenture

is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables
or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security
is received by the Trustee simultaneously with the creation of the creditor relationship arising from the making, drawing, negotiating
or Incurring of the draft, bill of exchange, acceptance or obligation.


 


SECTION 7.04.Trustee’s Disclaimer.
The Trustee (i) makes no representation as to the validity or adequacy of the Indenture or the Notes, (ii) is not accountable
for the Company’s use or application of the proceeds from the Notes and (iii) is not responsible for any statement in
the Notes other than its certificate of authentication.


 


SECTION 7.05.Notice of Default.
If any Default with respect to the Notes occurs and is continuing and is known to the Trustee, the Trustee will send notice of
the Default to each Holder within 90 days after it occurs, unless the Default has been cured; provided that,


 




    	37



    	 



    

except in the case of a default in the payment
of the principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the board
of directors, the executive committee or a trust committee of directors of the Trustee in good faith determines that withholding
the notice is in the interest of the Holders of the Notes. Notice to Holders under this Section will be given in the manner and
to the extent provided in Trust Indenture Act Section 313(c).


 


SECTION 7.06.Reports by Trustee
to Holders. Within 60 days after each May 15, beginning with May 15, 2016, the Trustee will mail to each

reasonable compensation and expenses of the Trustee’s agents and counsel.


 


(b)The Company will indemnify the Trustee

duties under the Indenture and the Notes, including the costs and expenses of defending itself against any claim or liability and
of complying with any process served upon it or any of its officers in connection with the exercise or performance of any of its
powers or duties under the Indenture and the Notes.


 


(c)To secure the Company’s payment
obligations in this Section, the Trustee will have a lien prior to the Notes on all money or property held or collected by the
Trustee, in its capacity as Trustee, except money or property held in trust to pay principal, premium, if any, of, and interest
on particular Notes.


 


(d)When the Trustee incurs expenses or
renders services in connection with an Event of Default, the expenses (including the reasonable charges and expenses of its counsel)

bankruptcy, insolvency or other similar law.

of appointment as provided in this Section.


 


(b)If the Trustee has been removed by
the Holders, Holders of a majority in principal amount of all then outstanding Notes may appoint a successor Trustee with the consent
of the Company. Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason,
the Company will promptly appoint a successor Trustee. If the successor Trustee does not deliver its written acceptance within
30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in
principal amount of all then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for
the appointment of a successor Trustee.

of a successor Trustee to all Holders, and include in the notice the name of the successor Trustee and the address of its Corporate

corporate trust business to, another corporation or national banking association, the resulting, surviving or transferee corporation

The Indenture must always have a Trustee that satisfies the requirements of Trust Indenture Act Section 310(a) and has a combined
capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition.


 


SECTION 7.11.Money Held in Trust.

any securities exchange upon which the Notes are listed. The Company agrees to reimburse the Trustee for any costs or expenses

SECTION 8.02.Defeasance and Discharge

interest and principal in respect thereof in accordance with their terms will provide not later than one day before the due date
of any payment referred to in subclause (x) or (y) of this clause (A) money in an amount, or (iii) a
combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee, to pay and discharge without consideration of the reinvestment of such
interest and after payment of all federal, state and local taxes or other charges and assessments in respect thereof payable by
the Trustee (x) the principal of, premium, if any, and each installment of interest on the outstanding Notes on the due dates
thereof and (y) any mandatory sinking fund payments or analogous payments applicable to the Notes on the day on which such

the Trustee (i) either (x) an Opinion of Counsel to the effect that beneficial owners of the Notes will not recognize
income, gain or loss for federal income tax purposes as a result of the Company’s exercise of its option under this Section 8.02
and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the
case if such deposit, defeasance and discharge had not occurred, which Opinion of Counsel must be based upon a ruling of the Internal
Revenue Service to the same effect or a change in applicable federal income tax law or related treasury regulations after the date
of this Indenture or


 




    	41



    	 



    

(y) a ruling directed to the
Company received from the Internal Revenue Service to the same effect as the aforementioned Opinion of Counsel and (ii) an
Opinion of Counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940,
as amended, and after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547
of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;


 


(C)immediately after giving effect
to such deposit on a pro form a basis, no Event of Default with respect to such Notes, or event that after the giving of notice
or lapse of time or both would become an Event of Default with respect to such Notes, shall have occurred and be continuing on
the date of such deposit or during the period ending on the 123rd day after the date of such deposit, and such deposit shall not
result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a
party or by which the Company is bound; and


 


(D)if at such time the Notes are
listed on a national securities exchange, the Company has delivered to the Trustee an Opinion of Counsel to the effect that the
Notes will not be delisted as a result of such deposit, defeasance and discharge.


 


If the Company shall be deemed to have
paid and shall be discharged from any and all obligations in respect of all of the Notes pursuant to this Section 8.02 and
all amounts outstanding to the Trustee hereunder or the Collateral Agent under the Pledge Agreement shall have been paid in full,
then the Company shall be released of its obligations under the Pledge Agreement and the Collateral shall be released from the
security interest granted in favor of the Collateral Agent thereunder.


 


SECTION 8.03.Defeasance of Certain
Obligations. The Company may omit to comply with any term, provision or condition set forth in, and this Indenture will no
longer be in effect with respect to, any covenant in Article 4 or Section 5.01 and clauses (iii), (iv) and
(vii) of Section 6.01 and Article 11 shall be deemed not to be an Event of Default, if:


 


(A)with reference to this Section 8.03,
the Company has deposited or caused to be irrevocably deposited with the Trustee (or another trustee satisfying the requirements
of Section 7.08) as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the
Holders of the Notes, (i) money in an amount or (ii) U.S. Government Obligations which through the payment of principal
and interest in respect thereof in accordance with their terms will provide not later than one day before the due dates thereof
or earlier redemption (irrevocably provided for under agreements satisfactory to the Trustee), as the case may be, of any payment
referred to in subclause (x) or (y) of this clause (A) money in an amount, or (iii) a combination
thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay and discharge without consideration of the reinvestment of such

interest and after payment of all
federal, state and local taxes or other charges and assessments in respect thereof payable by the Trustee (x) the principal
of, premium, if any, and each installment of interest on the outstanding Notes on the due date thereof or earlier redemption (irrevocably
provided for under arrangements satisfactory to the Trustee), as the case may be, and (y) any mandatory sinking fund payments
or analogous payments applicable to the Notes and the Indenture with respect to the Notes on the day on which such payments are
due and payable in accordance with the terms of the Notes and the Indenture with respect to the Notes;


 


(B)the Company has delivered to
the Trustee (i) an Opinion of Counsel to the effect that the beneficial owners will not recognize income, gain or loss for
federal income tax purposes as a result of the Company’s exercise of its option under this Section 8.03 and will be
subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such
deposit and defeasance had not occurred and (ii) an Opinion of Counsel to the effect that the creation of the defeasance trust
does not violate the Investment Company Act of 1940 and after the passage of 123 days following the deposit, the trust fund will
not be subject to the effect of Section 547 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and Creditor
Law;


 


(C)immediately after giving effect
to such deposit on a pro forma basis, no Event of Default or event that after the giving of notice or lapse of time or both would
become an Event of Default shall have occurred and be continuing on the date of such deposit or during the period ending on the
123rd day after the date of such deposit, and such deposit shall not result in a breach or violation of, or constitute a default
under, any other agreement or instrument to which the Company is a party or by which the Company is bound; and


 


(D)if at such time the Notes are
listed on a national securities exchange, the Company has delivered to the Trustee an Opinion of Counsel to the effect that such
Notes will not be delisted as a result of such deposit, defeasance and discharge.


 


If the Company shall have satisfied
each of the conditions set forth above in this Section 8.03 and all amounts outstanding to the Trustee hereunder or the Collateral
Agent under the Pledge Agreement shall have been paid in full, then the Company shall be released of its obligations under the
Pledge Agreement and the Collateral shall be released from the security interest granted in favor of the Collateral Agent thereunder.


 


SECTION 8.04.Application of Trust
Money. Subject to Section 8.05, the Trustee will hold in trust the money or U.S. Government Obligations deposited
with it pursuant to Sections 8.01, 8.02 or 8.03, and apply the deposited money and the proceeds from deposited U.S. Government
Obligations to the payment of principal of, premium, if any, and interest on the Notes in accordance with such Notes and the Indenture.
Such money and U.S. Government Obligations need not be segregated from other funds except to the extent required by law.


 




    	43



    	 



    

SECTION 8.05.Repayment to Company.
Subject to Sections 7.07, 8.01, 8.02 and 8.03, the Trustee will promptly pay to the Company upon request any excess money
held by the Trustee at any time and thereupon be relieved from all liability with respect to such money. The Trustee will pay to
the Company upon request any money held for payment with respect to the Notes that remains unclaimed for two years, provided
that before making such payment the Trustee may at the expense of the Company publish once in a newspaper of general circulation
in New York City, or send to each Holder of the Notes entitled to such money, notice that the money remains unclaimed and that
after a date specified in the notice (at least 30 days after the date of the publication or notice) any remaining unclaimed
balance of money will be repaid to the Company. After payment to the Company, Holders of the Notes entitled to such money must
look solely to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee with
respect to such money will cease.


 


SECTION 8.06.Reinstatement.
 If and for so long as the Trustee is unable to apply any money or U.S. Government Obligations held in trust pursuant to Sections 8.01,
8.02 or 8.03 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 obligations under the Indenture and the Notes will be
reinstated as though no such deposit in trust had been made. If the Company makes any payment of principal of, premium, if any,
or interest on the Notes because of the reinstatement of its obligations, it will be subrogated to the rights of the Holders of
such Notes to receive such payment from the money or U.S. Government Obligations held in trust.


 


Article 9



Amendments, Supplements and Waivers


 


SECTION 9.01.Amendments Without
Consent of Holders. (a) The Company and the Trustee may amend or supplement the Indenture or the Notes without notice
to or the consent of any Noteholder


 


(i)to cure any ambiguity, defect
or inconsistency in the Indenture or the Notes;


 


(ii)to comply with Section 5.01;


 


(iii)to comply with any requirements
of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act;


 


(iv)to evidence and provide
for the acceptance of appointment hereunder by a successor Trustee;


 


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


 




    	44



    	 



    

(vi)to provide for any guarantee
of the Notes, to secure-the Notes or to confirm and evidence the release, termination or discharge of any guarantee of or lien
securing the Notes when such release, termination or discharge is permitted by the Indenture;


 


(vii)to provide for or confirm
the issuance of Additional Notes;



or


 


(viii)to make any other change
that does not materially and adversely affect the rights of any Holder.


 


SECTION 9.02.Amendments With Consent
of Holders.  (a) Except as otherwise provided in Sections 6.02, 6.04 and 6.07 or paragraph (b), the Company
and the Trustee may amend the Indenture with respect to the Notes and the Notes with the written consent of the Holders of a majority
in principal amount of the outstanding Notes, and the Holders of a majority in principal amount of the outstanding Notes by written
notice to the Trustee may waive future compliance by the Company with any provision of the Indenture with respect to the Notes
or the Notes.


 


(b)Notwithstanding the provisions of paragraph (a),
without the consent of each Holder of Notes affected, an amendment or waiver may not:


 


(i)reduce the principal amount
of or change the stated maturity of any installment of principal of any Note;


 


(ii)reduce the rate of or change
the stated maturity of any interest payment on any Note;


 


(iii)reduce the amount payable
upon the redemption or any required repurchase of any Note or change the times at which any Note may be redeemed or repurchased
or, once notice of redemption or a Change of Control Offer has been given, the time at which it must thereupon be redeemed or repurchased;


 


(iv)make any Note payable in
money other than that stated in such Note;


 


(v)impair the right of any Holder
of Notes to receive any principal payment, premium payment, if any, or interest payment on such Holder’s Notes, on or after
the stated maturity thereof, or to institute suit for the enforcement of any such payment;


 


(vi)make any change in the percentage
of the principal amount of the Notes required for amendments or waivers; or


 


(vii)modify or change any provision
of the Indenture affecting the ranking of the Notes in a manner adverse to the Holders of the Notes.


 




    	45



    	 



    

(c)It is not necessary for Noteholders
to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if their consent approves the
substance thereof.


 


(d)An amendment, supplement or waiver
under this Section will become effective on receipt by the Trustee of written consents from the Holders of the requisite percentage
in principal amount of the outstanding Notes. After an amendment, supplement or waiver under this Section becomes effective, the
Company will send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. The Company
will send supplemental indentures to Holders upon request. Any failure of the Company to send such notice, or any defect therein,
will not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.


 


SECTION 9.03.Effect of Consent.
(a) After an amendment, supplement or waiver becomes effective, it will bind every Holder of Notes unless it is of the type requiring
the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder
affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note
that evidences the same debt as the Note of the consenting Holder.


 


(b)If an amendment, supplement or waiver
changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate
notation of the changed terms on the Note and return it to the Holder, or exchange it for a new Note that reflects the changed
terms. The Trustee may also place an appropriate notation on any Note thereafter authenticated. However, the effectiveness of the
amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.


 


SECTION 9.04.Trustee’s Rights
and Obligations. The Trustee shall be provided with, and will be fully protected in relying upon, an Opinion of Counsel
and an Officer’s Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to
this Article is authorized or permitted by the Indenture. Upon receipt of such an Opinion of Counsel and Officer’s Certificate,
it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The
Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee’s own rights,
duties or immunities under the Indenture.


 


SECTION 9.05.Conformity with Trust
Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the
Trust Indenture Act.


 


SECTION 9.06.Payments for Consents.
Neither the Company nor any of its Subsidiaries or Affiliates may, directly or indirectly, pay or cause to be paid any consideration,
whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture with respect to the Notes or the Notes unless such consideration is offered to be paid,
or agreed to be paid to all Holders of the Notes that consent, waive or agree to amend such term or provision within the time period
set forth in the solicitation documents relating to the consent, waiver or amendment.

Article 10



Miscellaneous


 


SECTION 10.01.Trust Indenture
Act of 1939.  The Indenture shall incorporate and be governed by the provisions of the Trust Indenture Act that are
required to be part of and to govern indentures qualified under the Trust Indenture Act.


 


SECTION 10.02.Noteholder Communications;
Noteholder Actions. (a)The rights of Holders to communicate with other Holders with respect to the Indenture or
the Notes are as provided by the Trust Indenture Act, and the Company and the Trustee shall comply with the requirements of Trust
Indenture Act Sections 312(a) and 312(b). Neither the Company nor the Trustee will be held accountable by reason of any disclosure
of information as to names and addresses of Holders made pursuant to the Trust Indenture Act.


 


(b)(i)Any request, demand, authorization,
direction, notice, consent to amendment, supplement or waiver or other action provided by this Indenture to be given or taken by
a Holder (an “Act”) may be evidenced by an instrument signed by the Holder delivered to the Trustee. The fact
and date of the execution of the instrument, or the authority of the person executing it, may be proved in any manner that the
Trustee deems sufficient.


 


(ii)The Trustee may make reasonable
rules for action by or at a meeting of Holders of Notes, which will be binding on all the Holders of Notes.


 


(c)Any Act by the Holder of any Note binds
that Holder and every subsequent Holder of a Note that evidences the same debt as the Note of the acting Holder, even if no notation
thereof appears on the Note. Subject to paragraph (d), a Holder may revoke an Act as to its Notes, but only if the Trustee
receives the notice of revocation before the date the amendment or waiver or other consequence of the act becomes effective.


 


(d)The Company may, but is not obligated
to, fix a record date (which need not be within the time limits otherwise prescribed by Trust Indenture Act Section 316(c))
for the purpose of determining the Holders of Notes entitled to Act with respect to any amendment or waiver or in any other regard,
except that during the continuance of an Event of Default with respect to the Notes, only the Trustee may set a record date as
to notices of default, any declaration or acceleration or any other remedies or other consequences of such Event of Default. If
a record date is fixed with respect to the Notes, those Persons that were Holders of Notes at such record date and only those Persons
will be entitled to act, or to revoke any previous act, whether or not those Persons continue to be Holders of Notes after the
record date. No Act will be valid or effective for more than 90 days after the record date.


 


SECTION 10.03.Notices.
 (a) Any notice or communication to the Company will be deemed given if in writing (i) when delivered in person or (ii) five
days after mailing when mailed by first class mail, or (iii) when sent by facsimile transmission, with transmission confirmed.

the notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and the waiver
will be the equivalent of the notice. Waivers of notice by Holders must be filed with the Trustee, but such filing is not a condition
precedent to the validity of any action taken in reliance upon such waivers.


 


SECTION 10.04.Certificate and
Opinion as to Conditions Precedent. Upon any request or application by the Company to the Trustee to take any action
under the Indenture, the Company will furnish to the Trustee:

an informed opinion as to whether or not such covenant or condition has been complied with; and


 


(iv)a statement as to whether
or not, in the opinion of each such person, such condition or covenant has been complied with, provided that an Opinion
of Counsel may rely on an Officers’ Certificate or certificates of public officials with respect to matters of fact.


 


SECTION 10.06.Payment Date Other
Than a Business Day. If any payment with respect to a payment of any principal of, premium, if any, or interest on any
Note (including any payment to be made on any date fixed for redemption or purchase of any Note) is due on a day which is not a

the same agreement.


 


SECTION 10.11.Separability.
 In case any provision in the Indenture or in the Notes is invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions will not in any way be affected or impaired thereby.


 


SECTION 10.12.Table of Contents
and Headings.  The Table of Contents, Cross-Reference Table and headings of the Articles and Sections of the Indenture
have been inserted for convenience of reference only, are not to be considered a part of the Indenture and in no way modify or
restrict any of the terms and provisions of the Indenture.


 


SECTION 10.13.No Liability of
Directors, Officers, Employees, Incorporators and Stockholders. No director, officer, employee, incorporator or stockholder
of the Company,


 




    	49



    	 



    

as such, will have any liability for any obligations
of the Company under the Notes, or the Indenture or for any claim based on, in respect of, or by reason of, such obligations. Each
Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration
for issuance of the Notes.


 


SECTION 10.14.Waiver of Jury Trial.
EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT

shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon
as practicable under the circumstances.

Notes and this Indenture to the Holders and the Trustee, according to the provisions of this Indenture or the Notes (the “Obligations”),
shall be secured, as provided in the Pledge Agreement. Each Holder of the Notes, by its acceptance thereof, consents and agrees
to the terms of the Pledge Agreement (including, without limitation, the provisions providing for foreclosure and release of Collateral)
as the same may be in effect or may be amended from time to time in accordance with its terms and authorizes and directs the Collateral
Agent to enter into the Pledge Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith.
The Company shall deliver to the Trustee copies of all documents delivered to the Collateral Agent pursuant to the Pledge Agreement,
and shall cause to be done all such acts and things as may be necessary or proper, or as may be required by the provisions of the
Pledge Agreement, to assure and confirm to the Trustee and the Collateral Agent that the security interest in the Collateral contemplated
hereby, by the Pledge Agreement or any parts thereof, as from time to time constituted, so as to render the same available for
the security and benefit of this Indenture and the Notes, secured hereby, according to the intent and purposes herein expressed.
The Company shall cause to be taken any and all actions reasonably required to cause the Pledge Agreement to create and maintain,
as security for the Obligations of the Company, hereunder, a valid and enforceable perfected Lien in and on all the Collateral,
in favor of the Collateral Agent for the benefit of the Trustee and Holders and other Secured Parties (as defined in the Pledge
Agreement), if any, and subject to no other Liens other than Liens permitted by Section 4.03(a) hereof.

in accordance with the provisions of the Pledge Agreement. In addition, subject to the terms of the Pledge Agreement, upon the
request of the Company pursuant to an Officers’ Certificate certifying that all conditions precedent hereunder have been
met and (at the sole cost and expense of the Company) the Collateral Agent shall release the Collateral that is sold, conveyed
or disposed of in compliance with the provisions of the Pledge Agreement and this Indenture. Upon receipt of such Officers’
Certificate, the Collateral Agent shall execute, deliver or acknowledge any necessary or proper instruments of termination, satisfaction
or release to evidence the release of any Collateral permitted to be released pursuant to this Indenture or the Pledge Agreement,

of Default with respect to the Notes shall have occurred and be continuing and the maturity of the Notes shall have been accelerated
(whether by declaration or otherwise) and the Trustee shall have delivered a notice of acceleration to the Collateral Agent, no
release of Collateral pursuant to the provisions of the Pledge Agreement shall be effective as against the Holders of Notes.


 


(c)The release of any Collateral from
the terms of this Indenture and the Pledge Agreement shall not be deemed to impair the security under this Indenture in contravention
of the provisions hereof if and to the extent the Collateral is released pursuant to the terms of this Indenture or the terms of
the Pledge Agreement. To the extent applicable, the Company shall cause TIA Section 313(b), relating to reports, and TIA Section 314(d),
relating to the release of property or securities from the Lien and security interest of the Pledge Agreement and relating to the
substitution therefor of any property or securities to be subjected to the Lien and security interest of the Pledge Agreement,

pursuant to the Pledge Agreement, (i) all documents required by TIA Section 314(d) and (ii) an Opinion of Counsel,

required by TIA Section 314(d).


 




    	51

the Trustee. In the event that the Company wishes to release Collateral in accordance with the Pledge Agreement and

Trustee has received, all documentation required by TIA Section 314(d) in connection with such release, and the Opinion of
Counsel delivered pursuant to Section 11.04, the Trustee shall deliver a certificate to the Collateral Agent setting forth

the terms of the Pledge Agreement and (b) collect and receive any and all amounts payable in respect of the Obligations of
the Company hereunder.


 


SECTION 11.07.Authorization of
Receipt of Refunds by the Trustee Under the Pledge Agreement. The Trustee is authorized to receive any funds distributed

such day is a Business Day. At least 15 days before a special record date, the Company will send to each Holder and to the
Trustee a notice that sets forth the special record date, the payment date and the amount of interest to be paid.


 


2.Indenture.


 


This is one of the Notes designated as “3.45%
Senior Secured Notes due 2020” (the “Notes”) issued under an indenture dated as of June 25, 2015 (as amended
from time to time) (the “Indenture”) between the Company and U.S. Bank National Association, as Trustee, (the
“Trustee”). Capitalized terms used herein are used as defined in the Indenture unless otherwise indicated. The
terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement
of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note
and the terms of the Indenture, the terms of the Indenture will control.


 


The Notes are general unsubordinated obligations
of the Company. The Notes are secured by a pledge by the Company of all of the outstanding common stock of the Company’s
principal subsidiary, Indianapolis Power & Light Company, pursuant to a Pledge Agreement


 




    	A-4



    	 



    

Supplement dated June 25, 2015 between the
Company and The Bank of New York Mellon Trust Company, N.A., as Collateral Agent, which supplements the Pledge Agreement dated
as of November 14, 2001 between the Company and the Collateral Agent. The Indenture limits the original aggregate principal
amount of the Notes to $405,000,000, but Additional Notes may be issued pursuant to the Indenture, and the originally issued Notes
and all such Additional Notes will be considered the same series of Notes.


 


3.Repurchase of Notes Upon a Change
of Control.


 


Upon the occurrence of a Change of Control
Triggering Event, the Holder of this Note will have the right to require the Company to repurchase all or any part (no note
of a principal amount of $2,000 or less will be repurchased in part) of this Note at a repurchase price in cash equal to 101% of
the principal amount of this Note plus accrued and unpaid interest, if any, to, but not including, the date of repurchase, as further
described in the Indenture.


 


4.Redemption; Discharge Prior to Redemption
or Maturity.


 


This Note is subject to optional redemption,
as further described in the Indenture. There is no sinking fund or mandatory redemption applicable to this Note.


 


If the Company deposits with the Trustee money
or U.S. Government Obligations sufficient to pay the then outstanding principal of, premium, if any, and accrued interest on the
Notes to redemption or maturity, the Company may in certain circumstances be discharged from the Indenture with respect to the
Notes or may be discharged from certain of its obligations under certain provisions of the Indenture with respect to the Notes.


 


5.Registered Form; Denominations; Transfer;
Exchange.


 


The Notes are in registered form without coupons
in minimum denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. A Holder may register the
transfer or exchange of Notes in accordance with the Indenture. The Trustee may require a Holder to furnish appropriate endorsements
and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Pursuant to the Indenture,
there are certain periods during which the Trustee will not be required to issue, register the transfer of or exchange any Note
or certain portions of a Note.


 


6.Defaults and Remedies.


 


If an Event of Default, as defined in the
Indenture, with respect to the Notes occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of
the Notes may declare all the Notes to be due and payable. If a bankruptcy or insolvency default with respect to the Company occurs
and is continuing, the Notes automatically become due and payable. Holders of the Notes may not enforce the Indenture or the Notes
except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or Notes.
Subject to certain limitations, Holders of a majority in principal amount of the Notes then outstanding may direct the Trustee
in its exercise of remedies.


 


7.Amendment and Waiver.


 




    	A-5



    	 



    

Subject to certain exceptions, the Indenture
with respect to the Notes and such Notes may be amended, or default may be waived, with the consent of the Holders of a majority
in principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company and the Trustee may amend
or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency.
