Issuer or the Indenture Trustee, and the Holders, by their acceptance of the Environmental Trust Bonds, waive any such Claim.

of all other amounts due under or in connection with this Indenture (including, without limitation, all fees, expenses, counsel
fees and other amounts due and owing to the Indenture Trustee) and the performance and observance of all of the covenants and conditions
contained herein or in the Environmental Trust Bonds, has hereby executed and delivered this Indenture and by these presents does
hereby and under the Series Supplement will convey, grant, assign, transfer and pledge, in each case, in and unto the Indenture

required or permitted by this Indenture or by the Series Supplement and may have such letters, numbers or other marks of

The Environmental Trust Bonds shall be typewritten,
printed, lithographed or engraved or produced by any combination of these methods (with or without steel engraved borders), all
as determined by the officers executing the Environmental Trust Bonds, as evidenced by their execution of the Environmental Trust
Bonds.


 


Each Environmental Trust Bond shall be dated
the date of its authentication. The terms of the Environmental Trust Bonds set forth in Exhibit A are part of the terms
of this Indenture.


 


Section 2.02.     
Denominations: Environmental Trust Bonds Issuable in Series. The Environmental Trust Bonds shall be issuable in the
Minimum Denomination specified in the Series Supplement and, except as otherwise provided in the Series Supplement, in integral
multiples of $1,000 in excess thereof.


 


The Environmental Trust Bonds may, at the
election of and as authorized by a Responsible Officer of the Issuer, be issued in one or more Tranches, and shall be designated
generally as the “Environmental Trust Bonds, Series 2021” of the Issuer, with such further particular designations
added or incorporated in such title for the Environmental Trust Bonds of any particular Tranche as a Responsible Officer of the
Issuer may determine. Each Environmental Trust Bond shall bear upon its face the designation so selected for the Tranche to which
it belongs. All Environmental Trust Bonds shall be identical in all respects except for the denominations thereof, the Holder thereof,
the numbering thereon and the legends thereon, unless the Environmental Trust Bonds are comprised of one or more Tranches, in which
case all of the Environmental Trust Bonds of the same Tranche shall be identical in all respects except for the denominations thereof,
the Holder thereof, the numbering thereon, the legends thereon and the CUSIP number thereon. All Environmental Trust Bonds of a
particular Tranche shall be in all respects equally and ratably entitled to the benefits hereof without preference, priority or
distinction on account of the actual time or times of authentication and delivery, all in accordance with the terms and provisions
of this Indenture.


 


The Environmental Trust Bonds shall be created
by the Series Supplement authorized by a Responsible Officer of the Issuer, which shall specify and establish the terms and provisions

(f)               
 the Scheduled Final Payment Date;


 


(g)              
the Final Maturity Date;


 


(h)

(i)               
the Minimum Denominations;


 


(j)               
the Expected Amortization Schedule;


 


(k)

whether or not the Environmental Trust Bonds are to be Book-Entry Environmental Trust Bonds and the extent to which Section
2.11 should apply; and


 


(m)              any
other provisions expressing or referring to the terms and conditions upon which the Environmental Trust Bonds of any Tranche are
to be issued under this Indenture that are not in conflict with the provisions of this Indenture and as to which the Rating Agency
Condition is satisfied.


 


Section 2.03.     
Execution, Authentication and Delivery. The Environmental Trust Bonds shall be executed on behalf of the Issuer by
any of its Responsible Officers. The signature of any such Responsible Officer on the Environmental Trust Bonds may be manual or
facsimile.


 


Environmental Trust Bonds bearing the manual
or facsimile signature of individuals who were at the time of such execution Responsible Officers of the Issuer shall bind the
Issuer, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery
of the Environmental Trust Bonds or did not hold such offices at the date of the Environmental Trust Bonds.


 


At any time and from time to time after the
execution and delivery of this Indenture, the Issuer may deliver Environmental Trust Bonds executed by the Issuer to the Indenture
Trustee pursuant to an Issuer Order for authentication; and the Indenture Trustee shall authenticate and deliver the Environmental
Trust Bonds as in this Indenture provided and not otherwise.


 


No Environmental Trust Bond shall be entitled
to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Environmental Trust
Bond a certificate of authentication substantially in the form provided for therein executed by the Indenture Trustee by the manual
signature of one of its authorized signatories, and such certificate upon any Environmental Trust Bond shall be conclusive evidence,
and the only evidence, that such Environmental Trust Bond has been duly authenticated and delivered hereunder.


 






     4


     


    

 


Section 2.04.      Temporary
Environmental Trust Bonds. Pending the preparation of Definitive Environmental Trust Bonds pursuant to Section
2.13, the Issuer may execute, and upon receipt of an Issuer Order the Indenture Trustee shall authenticate and deliver,
Temporary Environmental Trust Bonds which are printed, lithographed, typewritten, mimeographed or otherwise produced, of the
tenor of the Definitive Environmental Trust Bonds in lieu of which they are issued and with such variations not inconsistent
with the terms of this Indenture as the officers executing the Environmental Trust Bonds may determine, as evidenced by their
execution of the Environmental Trust Bonds.


 


If Temporary Environmental Trust Bonds are
issued, the Issuer will cause Definitive Environmental Trust Bonds to be prepared without unreasonable delay. After the preparation
of Definitive Environmental Trust Bonds, the Temporary Environmental Trust Bonds shall be exchangeable for Definitive Environmental
Trust Bonds upon surrender of the Temporary Environmental Trust Bonds at the office or agency of the Issuer to be maintained as
provided in Section 3.02, without charge to the Holder. Upon surrender for cancellation of any one or more Temporary Environmental
Trust Bonds, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver in exchange therefor a like principal
amount of Definitive Environmental Trust Bonds of minimum denominations. Until so delivered in exchange, the Temporary Environmental
Trust Bonds shall in all respects be entitled to the same benefits under this Indenture as Definitive Environmental Trust Bonds.


 


Section 2.05.     
Registration; Registration of Transfer and Exchange of Environmental Trust Bonds. The Issuer shall cause to be kept
a register (the “Environmental Trust Bond Register”) in which, subject to such reasonable regulations as it
may prescribe, the Issuer shall provide for the registration of Environmental Trust Bonds and the registration of transfers of
Environmental Trust Bonds. The Indenture Trustee shall be “Environmental Trust Bond Registrar” for the purpose
of registering the Environmental Trust Bonds and transfers of Environmental Trust Bonds as herein provided. Upon any resignation
of any Environmental Trust Bond Registrar, the Issuer shall promptly appoint a successor or, if it elects not to make such an appointment,
assume the duties of Environmental Trust Bond Registrar.


 


If a Person other than the Indenture Trustee
is appointed by the Issuer as Environmental Trust Bond Registrar, the Issuer will give the Indenture Trustee prompt written notice
of the appointment of such Environmental Trust Bond Registrar and of the location, and any change in the location, of the Environmental
Trust Bond Register, and the Indenture Trustee shall have the right to inspect the Environmental Trust Bond Register at all reasonable
times and to obtain copies thereof, and the Indenture Trustee shall have the right to rely conclusively upon a certificate executed
on behalf of the Environmental Trust Bond Registrar by a Responsible Officer thereof as to the names and addresses of the Holders
and the principal amounts and number of the Environmental Trust Bonds (separately stated by Tranche).


 


Upon surrender for registration of transfer
of any Environmental Trust Bond at the office or agency of the Issuer to be maintained as provided in Section 3.02, provided
that the requirements of Section 8-401 of the UCC are met, the Issuer shall execute, and the Indenture Trustee shall authenticate
and the Holder shall obtain from the Indenture Trustee, in the name of the designated transferee or transferees, one or more new
Environmental Trust Bonds in any Minimum Denominations, of the same Tranche and aggregate principal amount.


 






     5


     


    

 


At the option of the Holder, Environmental
Trust Bonds may be exchanged for other Environmental Trust Bonds in any Minimum Denominations, of the same Tranche and aggregate
principal amount, upon surrender of the Environmental Trust Bonds to be exchanged at such office or agency as provided in Section
3.02. Whenever any Environmental Trust Bonds are so surrendered for exchange, the Issuer shall, provided that the requirements
of Section 8-401 of the UCC are met, execute, and, upon any such execution, the Indenture Trustee shall authenticate and the Holder
shall obtain from the Indenture Trustee, the Environmental Trust Bonds which the Holder making the exchange is entitled to receive.


 


All Environmental Trust Bonds issued upon
any registration of transfer or exchange of other Environmental Trust Bonds shall be the valid obligations of the Issuer, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the Environmental Trust Bonds surrendered upon such registration
of transfer or exchange.


 


Every Environmental Trust Bond presented or

to Section 2.04 or Section 2.06 not involving any transfer.


 


The preceding provisions of this Section
2.05 notwithstanding, the Issuer shall not be required to make, and the Environmental Trust Bond Registrar need not register,

Section 2.06.      Mutilated,

Environmental Trust Bond and (b) there is delivered to the Indenture Trustee such security or indemnity as may be required by
it to hold the Issuer and the Indenture Trustee harmless, then, in the absence of notice to the Issuer, the Environmental
Trust Bond Registrar or the Indenture Trustee that such Environmental Trust Bond has been acquired by a Protected Purchaser,
the Issuer shall, provided that the requirements of Section 8-401 of the UCC are met, execute, and, upon the Issuer’s
written request, the Indenture Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Environmental Trust Bond, a replacement Environmental Trust Bond of like Tranche and principal
amount, bearing a number not contemporaneously outstanding; provided, however, that, if any such destroyed,
lost or stolen Environmental Trust Bond, but not a mutilated Environmental Trust Bond, shall have become or within seven (7)

lost or stolen Environmental Trust Bond when so due or payable without surrender thereof. If, after the delivery of such
replacement Environmental Trust Bond or payment of a destroyed, lost or stolen Environmental Trust Bond pursuant to the
proviso to the preceding sentence, a Protected Purchaser of the original Environmental Trust Bond in lieu of which such
replacement Environmental Trust Bond was issued presents for payment such original Environmental Trust Bond, the Issuer and

entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense
incurred by the Issuer or the Indenture Trustee in connection therewith.

Trust Bond under this Section 2.06, the Issuer and/or the Indenture Trustee may require the payment by the Holder of such
Environmental Trust Bond of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto
and any other reasonable expenses (including the fees and expenses of the Indenture Trustee and the Environmental Trust Bond Registrar)
in connection therewith.


 


Every replacement Environmental Trust Bond
issued pursuant to this Section 2.06 in replacement of any mutilated, destroyed, lost or stolen Environmental Trust Bond
shall constitute an original additional contractual obligation of the Issuer, whether or not the mutilated, destroyed, lost or
stolen Environmental Trust Bond shall be found at any time or enforced by any Person, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Environmental Trust Bonds duly issued hereunder.


 


The provisions of this Section 2.06
are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Environmental Trust Bonds.


 


Section 2.07.     
Persons Deemed Owner. Prior to due presentment for registration of transfer of any Environmental Trust Bond, the
Issuer, the Indenture Trustee, the Environmental Trust Bond Registrar and any agent of the Issuer or the Indenture Trustee may

Environmental Trust Bond for the purpose of receiving payments of principal of and premium, if any, and interest on such Environmental
Trust Bond and for all other purposes whatsoever, whether or not such Environmental Trust Bond be overdue, and none of the Issuer,
the Indenture Trustee or any agent of the Issuer or the Indenture Trustee shall be affected by notice to the contrary.

Section 2.08.     
Payment of Principal, Premium, if any, and Interest; Interest on Overdue Principal; Principal, Premium, if any, and Interest
Rights Preserved.


 


(a)              
 The Environmental Trust Bonds shall accrue interest as provided in the Series Supplement at the applicable Environmental
Trust Bond Interest Rate, and such interest shall be payable on each applicable Payment Date. Any installment of interest, principal
or premium, if any, payable on any Environmental Trust Bond which is punctually paid or duly provided for on the applicable Payment
Date shall be paid to the Person in whose name such Environmental Trust Bond (or one or more Predecessor Environmental Trust Bonds)
is registered on the Record Date for the applicable Payment Date by check mailed first-class, postage prepaid, to the Person whose
name appears as the Registered Holder (or by wire transfer to an account maintained by such Holder) in accordance with payment
instructions delivered to the Indenture Trustee by such Holder, and, with respect to Book-Entry Environmental Trust Bonds, payments
will be made by wire transfer in immediately available funds to the account designated by the Holder of the applicable Global Environmental
Trust Bond unless and until such Global Environmental Trust Bond is exchanged for Definitive Environmental Trust Bonds (in which
event payments shall be made as provided above) and except for the final installment of principal and premium, if any, payable
with respect to such Environmental Trust Bond on a Payment Date, which shall be payable as provided below.


 


(b)              
The principal of each Environmental Trust Bond of each Tranche shall be paid, to the extent funds are available therefor
in the Collection Account, in installments on each Payment Date as specified in the Series Supplement; provided, that installments
of principal not paid when scheduled to be paid in accordance with the Expected Amortization Schedule shall be paid upon receipt
of money available for such purpose, in the order set forth in Section 8.02(e). Failure to pay principal in accordance with
such Expected Amortization Schedule because moneys are not available pursuant to Section 8.02 to make such payments shall
not constitute a Default or Event of Default under this Indenture; provided, however, that failure to pay the entire
unpaid principal amount of the Environmental Trust Bonds of a Tranche upon the Final Maturity Date for the Environmental Trust
Bonds of such Tranche shall constitute an Event of Default under this Indenture as set forth in Section 5.01. Notwithstanding
the foregoing, the entire unpaid principal amount of the Environmental Trust Bonds shall be due and payable, if not previously
paid, on the date on which an Event of Default shall have occurred and be continuing, if the Indenture Trustee or the Holders of
the Environmental Trust Bonds representing not less than a majority of the Outstanding Amount of the Environmental Trust Bonds
have declared the Environmental Trust Bonds to be immediately due and payable in the manner provided in Section 5.02. All
payments of principal and premium, if any, on the Environmental Trust Bonds shall be made pro rata to the Holders entitled thereto
unless otherwise provided in the Series Supplement. The Indenture Trustee shall notify the Person in whose name an Environmental
Trust Bond is registered at the close of business on the Record Date preceding the Payment Date on which the Issuer expects that
the final installment of principal of and premium, if any, and interest on such Environmental Trust Bond will be paid. Such notice
shall be mailed no later than five (5) days prior to such final Payment Date and shall specify that such final installment will
be payable only upon presentation and surrender of such Environmental Trust Bond and shall specify the place where such Environmental
Trust Bond may be presented and surrendered for payment of such installment.


 


(c)               If
interest on the Environmental Trust Bonds is not paid when due, such defaulted interest shall be paid (plus interest on such
defaulted interest at the applicable Environmental Trust Bond Interest Rate to the extent lawful) to the Persons who are
Holders on a subsequent Special Record Date, which date shall be at least fifteen (15) Business Days prior to the Special
Payment Date. The Issuer shall fix or cause to be fixed any such Special Record Date and Special Payment Date, and, at least
ten (10) days before any such Special Record Date, the Issuer shall mail to each affected Holder a notice that states the
Special Record Date, the Special Payment Date and the amount of defaulted interest (plus interest on such defaulted interest)
to be paid.

Intermediary of the Collection Account to comply with entitlement orders of any Person other than the Indenture Trustee; and


 


(l)       all
of the Environmental Trust Bond Collateral constituting investment property has been and will have been credited to the Collection
Account or a subaccount thereof, and the Securities Intermediary for the Collection Account has agreed to treat all assets credited
to the Collection Account (other than cash) as “financial assets” within the meaning of the UCC.


 


Accordingly, the Indenture Trustee has a
first priority perfected security interest in the Collection Account, all funds and financial assets on deposit therein, and all
securities entitlements relating thereto. The representations and warranties set forth in this Section 2.18 shall survive
the execution and delivery of this Indenture and the issuance of any Environmental Trust Bonds, shall be deemed re-made on each
date on which any funds in the Collection Account are distributed to the Issuer or otherwise released from the Lien of the Indenture
and may not be waived by any party hereto except pursuant to a supplemental indenture executed in accordance with Article IX
and as to which the Rating Agency Condition has been satisfied.

Maintenance of Office or Agency. The Issuer shall initially maintain in Milwaukee, Wisconsin an office or agency
where Environmental Trust Bonds may be surrendered for registration of transfer or exchange. The Issuer shall give prompt written

Money for Payments To Be Held in Trust. As provided in Section 8.02(a), all payments of amounts due and payable
with respect to any Environmental Trust Bonds that are to be made from amounts withdrawn from the Collection Account pursuant to

except as provided in this Section 3.03 and Section 8.02.


 


Each Paying Agent shall meet the eligibility
criteria set forth for any Indenture Trustee under Section 6.11. The Issuer will cause each Paying Agent other than the
Indenture Trustee to execute and deliver to the Indenture Trustee an instrument in which such Paying Agent shall agree with the
Indenture Trustee (and if the Indenture Trustee acts as Paying Agent, it hereby so agrees), subject to the provisions of this Section
3.03, that such Paying Agent will:


 


(a)           hold
all sums held by it for the payment of amounts due with respect to the Environmental Trust Bonds in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided and pay such
sums to such Persons as herein provided;


 


(b)           give
the Indenture Trustee, unless the Indenture Trustee is the Paying Agent, and the Rating Agencies written notice of any Default
by the Issuer of which it has actual knowledge in the making of any payment required to be made with respect to the Environmental
Trust Bonds;


 


(c)           at
any time during the continuance of any such Default, upon the written request of the Indenture Trustee, forthwith pay to the Indenture
Trustee all sums so held in trust by such Paying Agent;


 


(d)           immediately, with notice to the Rating Agencies, resign as a Paying Agent and forthwith pay to the Indenture Trustee all
sums held by it in trust for the payment of Environmental Trust Bonds if at any time the Paying Agent determines that it has ceased
to meet the standards required to be met by a Paying Agent at the time of such determination; and


 


(e)           comply with all requirements of the Code, the Treasury regulations promulgated thereunder and other tax laws with respect
to the withholding from any payments made by it on any Environmental Trust Bonds of any applicable withholding taxes imposed thereon
and with respect to any applicable reporting requirements in connection therewith.

The Issuer may at any time, for the purpose
of obtaining the satisfaction and discharge of this Indenture or for any other purpose, by Issuer Order direct any Paying Agent
to pay to the Indenture Trustee all sums held in trust by such Paying Agent, such sums to be held by the Indenture Trustee upon
the same trusts as those upon which the sums were held by such Paying Agent; and, upon such payment by any Paying Agent to the
Indenture Trustee, such Paying Agent shall be released from all further liability with respect to such money.


 


Subject to applicable laws with respect to
escheatment of funds, any money held by the Indenture Trustee or any Paying Agent in trust for the payment of any amount due with
respect to any Environmental Trust Bond and remaining unclaimed for two (2) years after such amount has become due and payable
shall be discharged from such trust and be paid to the Issuer upon receipt of an Issuer Request; and, subject to Section 10.16,
the Holder of such Environmental Trust Bond shall thereafter, as an unsecured general creditor, look only to the Issuer for payment
thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture Trustee or such Paying
Agent with respect to such trust money shall thereupon cease; provided, however, that the Indenture Trustee or such
Paying Agent, before being required to make any such repayment, may at the expense of the Issuer, cause to be published once, in
a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City
of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty
(30) days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. The
Indenture Trustee may also adopt and employ, at the expense of the Issuer, any other reasonable means of notification of such repayment
(including mailing notice of such repayment to Holders whose right to or interest in moneys due and payable but not claimed is
determinable from the records of the Indenture Trustee or of any Paying Agent, at the last address of record for each such Holder).


 


Section 3.04.     
Existence. The Issuer shall keep in full effect its existence, rights and franchises as a limited liability company

laws of any other State or of the United States of America, in which case the Issuer will keep in full effect its existence, rights
and franchises under the laws of such other jurisdiction) and will obtain and preserve its qualification to do business in each
jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Indenture,
the other Basic Documents, the Environmental Trust Bonds, the Environmental Trust Bond Collateral and each other instrument or
agreement referenced herein or therein.

Performance of Obligations; Servicing; SEC Filings.


 


(a)           The Issuer (i) shall diligently pursue any and all actions to enforce its rights under each instrument or agreement included
in the Environmental Trust Bond Collateral and (ii) shall not take any action and shall use its best efforts not to permit any
action to be taken by others that would release any Person from any of such Person’s covenants or obligations under any such
instrument or agreement or that would result in the amendment, hypothecation, subordination, termination or discharge of, or impair
the validity or effectiveness of, any such instrument or agreement, except, in each case, as expressly provided in this Indenture,
the Series Supplement, the Sale Agreement, the Servicing Agreement, any Intercreditor Agreement or such other instrument or agreement.


 


(b)           The
Issuer may contract with other Persons to assist it in performing its duties under this Indenture, and any performance of such
duties by a Person identified to the Indenture Trustee herein or in an Officer’s Certificate shall be deemed to be action
taken by the Issuer. Initially, the Issuer has contracted with the Servicer to assist the Issuer in performing its duties under

(d)           If
the Issuer shall have knowledge of the occurrence of a Servicer Default under the Servicing Agreement, the Issuer shall promptly
give written notice thereof to the Indenture Trustee and the Rating Agencies and shall specify in such notice the response or
action, if any, the Issuer has taken or is taking with respect to such Servicer Default. If a Servicer Default shall arise from
the failure of the Servicer to perform any of its duties or obligations under the Servicing Agreement with respect to the Environmental
Control Property, the Environmental Trust Bond Collateral or the Environmental Control Charges, the Issuer shall take all reasonable
steps available to it to remedy such failure.


 


(e)           As

(f)           
in the case of an exercise of the Covenant Defeasance Option, the Issuer shall have delivered to the Indenture Trustee an

the Issuer delivers to the Indenture Trustee an Opinion of Counsel of external counsel of the Issuer to the effect that:

the court would hold that the deposited moneys or U.S. Government Obligations would not be in the bankruptcy estate of Wisconsin
Electric (or any of its Affiliates, other than the Issuer, that deposited the moneys or U.S. Government Obligations); and (ii)
in the event Wisconsin Electric (or any of its Affiliates, other than the Issuer, that deposited the moneys or U.S. Government
Obligations) were to be a debtor in a case under the Bankruptcy Code, the court would not disregard the separate legal existence
of Wisconsin Electric (or any of its Affiliates, other than the Issuer, that deposited the moneys or U.S. Government Obligations)
and the Issuer so as to order substantive consolidation under the Bankruptcy Code of the Issuer’s assets and liabilities
with the assets and liabilities of Wisconsin Electric or such other Affiliate; and

Rating Agency Condition shall have been satisfied with respect to the exercise of any Legal Defeasance Option or Covenant Defeasance
Option.

may determine, to the Holders of the particular Environmental Trust Bonds for the payment of which such moneys have been deposited
with the Indenture Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest; but such moneys
need not be segregated from other funds except to the extent required herein or in the Servicing Agreement or required by law.
Notwithstanding anything to the contrary in this Article IV, the Indenture Trustee shall deliver or pay to the Issuer from
time to time upon Issuer Request any moneys or U.S. Government Obligations held by it pursuant to Section 4.02 which, in
the opinion of a nationally recognized firm of Independent registered public accountants expressed in a written certification thereof
delivered to the Indenture Trustee (and not at the cost or expense of the Indenture Trustee), are in excess of the amount thereof

that any such payment shall be subject to the satisfaction of the Rating Agency Condition.

Collateral, or ordering the winding-up or liquidation of the Issuer’s affairs, and such decree or order shall remain unstayed
and in effect for a period of ninety (90) consecutive days;


 


(f)           
the commencement by the Issuer of a voluntary case under any applicable U.S. federal or state bankruptcy, insolvency or
other similar law now or hereafter in effect, or the consent by the Issuer to the entry of an order for relief in an involuntary
case or proceeding under any such law, or the consent by the Issuer to the appointment or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Issuer or for any substantial part of the Environmental Trust
Bond Collateral, or the making by the Issuer of any general assignment for the benefit of creditors, or the failure by the Issuer
generally to pay its debts as such debts become due, or the taking of action by the Issuer in furtherance of any of the foregoing;
or


 


(g)          
any act or failure to act by the State of Wisconsin or any of its agencies (including the PSCW), officers or employees which
violates or is not in accordance with the State Pledge.


 






     35


     


    

 


The Issuer shall deliver to a Responsible
Officer of the Indenture Trustee and to the Rating Agencies, within five (5) days after a Responsible Officer of the Issuer has
knowledge of the occurrence thereof, written notice in the form of an Officer’s Certificate of any event (i) which is an
Event of Default under Section 5.01(a), Section 5.01(b), Section 5.01(f) or Section 5.01(g) or (ii)
that with the giving of notice, the lapse of time, or both, would become an Event of Default under Section 5.01(c), Section
5.01(d) or Section 5.01(e), including, in each case, the status of such Default or Event of Default and what action
the Issuer is taking or proposes to take with respect thereto.


 


Section 5.02.     
Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default under
Section 5.01(g)) should occur and be continuing, then and in every such case the Indenture Trustee or the Holders representing
not less than a majority of the Outstanding Amount of the Environmental Trust Bonds may declare the Environmental Trust Bonds to
be immediately due and payable, by a notice in writing to the Issuer (and to the Indenture Trustee if given by Holders), and upon
any such declaration the unpaid principal amount of the Environmental Trust Bonds, together with accrued and unpaid interest thereon
through the date of acceleration, shall become immediately due and payable.


 


At any time after such declaration of acceleration
of maturity has been made and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee
as hereinafter in this Article V provided, the Holders representing not less than a majority of the Outstanding Amount of
the Environmental Trust Bonds, by written notice to the Issuer and the Indenture Trustee, may rescind and annul such declaration
and its consequences if:


 


(a)           
the Issuer has paid or deposited with the Indenture Trustee a sum sufficient to pay:


 


(i)            all
payments of principal of and premium, if any, and interest on all Environmental Trust Bonds due and owing at such time as if such
Event of Default had not occurred and was not continuing and all other amounts that would then be due hereunder or upon the Environmental
Trust Bonds if the Event of Default giving rise to such acceleration had not occurred; and


 


(ii)         
all sums paid or advanced by the Indenture Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Indenture Trustee and its agents and counsel; and


 


(b)          
all Events of Default, other than the nonpayment of the principal of the Environmental Trust Bonds that has become due solely
by such acceleration, have been cured or waived as provided in Section 5.12.


 


No such rescission shall affect any subsequent
default or impair any right consequent thereto.


 






     36


     


    

 


Section 5.03.     
Collection of Indebtedness and Suits for Enforcement by Indenture Trustee.


 


(a)        If
an Event of Default under Section 5.01(a) or Section 5.01(b) has occurred and is continuing, subject to Section
10.18, the Indenture Trustee, in its own name and as trustee of an express trust, may institute a Proceeding for the
collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and, subject to the
limitations on recourse set forth herein, may enforce the same against the Issuer or other obligor upon the Environmental
Trust Bonds and collect in the manner provided by law out of the property of the Issuer or other obligor upon the
Environmental Trust Bonds, wherever situated the moneys payable, or the Environmental Trust Bond Collateral and the proceeds
thereof, the whole amount then due and payable on the Environmental Trust Bonds for principal, premium, if any, and interest,
with interest upon the overdue principal and premium, if any, and, to the extent payment at such rate of interest shall be
legally enforceable, upon overdue installments of interest, at the respective rate borne by the Environmental Trust Bonds or
the applicable Tranche and in addition thereto 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 Indenture Trustee and its
agents and external counsel.


 


(b)         
If an Event of Default (other than an Event of Default under Section 5.01(g)) occurs and is continuing, the Indenture
Trustee shall, as more particularly provided in Section 5.04, proceed to protect and enforce its rights and the rights of
the Holders, by such appropriate Proceedings as the Indenture Trustee shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy or legal or equitable right vested in the Indenture Trustee by this Indenture
and the Series Supplement or by law, including foreclosing or otherwise enforcing the Lien of the Environmental Trust Bond Collateral
securing the Environmental Trust Bonds or applying to a court of competent jurisdiction for sequestration of revenues arising with
respect to the Environmental Control Property.


 


(c)         
If an Event of Default under Section 5.01(e) or Section 5.01(f) has occurred and is continuing, the Indenture
Trustee, irrespective of whether the principal of any Environmental Trust Bonds shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions
of this Section 5.03, shall be entitled and empowered, by intervention in any Proceedings related to such Event of Default
or otherwise:


 


(i)           
to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest owing and unpaid in
respect of the Environmental Trust Bonds and to file such other papers or documents as may be necessary or advisable in order to
have the claims of the Indenture Trustee (including any claim for reasonable compensation to the Indenture Trustee and each predecessor
Indenture Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred,
and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee, except as a result of negligence or bad
faith) and of the Holders allowed in such Proceedings;


 


(ii)       
unless prohibited by applicable law and regulations, to vote on behalf of the Holders in any election of a trustee in bankruptcy,
a standby trustee or Person performing similar functions in any such Proceedings;


 






     37


     


    

 


(iii)       
 to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute all amounts
received with respect to the claims of the Holders and of the Indenture Trustee on their behalf; and


 


(iv)        
to file such proofs of claim and other papers and documents as may be necessary or advisable in order to have the claims
of the Indenture Trustee or the Holders allowed in any judicial proceeding relative to the Issuer, its creditors and its property;


 


and any trustee, receiver, liquidator, custodian
or other similar official in any such Proceeding is hereby authorized by each of such Holders to make payments to the Indenture
Trustee, and, in the event that the Indenture Trustee shall consent to the making of payments directly to such Holders, to pay
to the Indenture Trustee such amounts as shall be sufficient to cover reasonable compensation to the Indenture Trustee, each predecessor
Indenture Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all
advances made, by the Indenture Trustee and each predecessor Indenture Trustee except as a result of negligence or bad faith.


 


(d)         
Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize or consent to or vote for or accept
or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Environmental
Trust Bonds or the rights of any Holder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any Holder
in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person.


 


(e)         
All rights of action and of asserting claims under this Indenture, or under any of the Environmental Trust Bonds, may be
enforced by the Indenture Trustee without the possession of any of the Environmental Trust Bonds or the production thereof in any
trial or other Proceedings relative thereto, and any such action or proceedings instituted by the Indenture Trustee shall be brought
in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements
and compensation of the Indenture Trustee, each predecessor Indenture Trustee and their respective agents and attorneys, shall
be for the ratable benefit of the Holders of the Environmental Trust Bonds.


 


(f)          In
any Proceedings brought by the Indenture Trustee (and also any Proceedings involving the interpretation of any provision of this
Indenture to which the Indenture Trustee shall be a party), the Indenture Trustee shall be held to represent all the Holders of
the Environmental Trust Bonds, and it shall not be necessary to make any Holder a party to any such Proceedings.


 


Section 5.04.     
Remedies; Priorities.


 


(a)         
If an Event of Default (other than an Event of Default under Section 5.01(g)) shall have occurred and be continuing,
the Indenture Trustee may do one or more of the following (subject to Section 5.05):


 


(i)            institute
Proceedings in its own name and as trustee of an express trust for the collection of all amounts then payable on the
Environmental Trust Bonds or under this Indenture with respect thereto, whether by declaration of acceleration or otherwise,
and, subject to the limitations on recovery set forth herein, enforce any judgment obtained, and collect from the Issuer or
any other obligor moneys adjudged due, upon the Environmental Trust Bonds;


 






     38


     


    

 


(ii)        
institute Proceedings from time to time for the complete or partial foreclosure of this Indenture with respect to the Environmental
Trust Bond Collateral;


 


(iii)       
exercise any remedies of a secured party under the UCC, the Statute or any other applicable law and take any other appropriate
action to protect and enforce the rights and remedies of the Indenture Trustee and the Holders of the Environmental Trust Bonds;


 


(iv)         
at the written direction of the Holders of a majority of the Outstanding Amount of the Environmental Trust Bonds, either
sell the Environmental Trust Bond Collateral or any portion thereof or rights or interest therein, at one or more public or private
sales called and conducted in any manner permitted by law, or elect that the Issuer maintain possession of all or a portion of
the Environmental Trust Bond Collateral pursuant to Section 5.05 and continue to apply the EC Charge Collection as if there
had been no declaration of acceleration; and


 


(v)          
exercise all rights, remedies, powers, privileges and claims of the Issuer against the Seller, the Administrator, Wisconsin
Electric or the Servicer under or in connection with, and pursuant to the terms of, the Sale Agreement, the Administration Agreement,
any Intercreditor Agreement or the Servicing Agreement;


 


provided, however, that the
Indenture Trustee may not sell or otherwise liquidate any portion of the Environmental Trust Bond Collateral following such an
Event of Default, other than an Event of Default described in Section 5.01(a) or Section 5.01(b) unless (A) the Holders
of 100 percent of the Outstanding Amount of the Environmental Trust Bonds consent thereto, (B) the proceeds of such sale or liquidation
distributable to the Holders are sufficient to discharge in full all amounts then due and unpaid upon the Environmental Trust Bonds
for principal, premium, if any, and interest after taking into account payment of all amounts due prior thereto pursuant to the
priorities set forth in Section 8.02(e) or (C) the Indenture Trustee determines that the Environmental Trust Bond Collateral
will not continue to provide sufficient funds for all payments on the Environmental Trust Bonds as they would have become due if
the Environmental Trust Bonds had not been declared due and payable, and the Indenture Trustee obtains the written consent of Holders
of at least 66 2/3 percent of the Outstanding Amount of the Environmental Trust Bonds. In determining such sufficiency or insufficiency
with respect to clause (B) above and clause (C) above, the Indenture Trustee may, but need not, obtain and conclusively rely upon
an opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed
action and as to the sufficiency of the Environmental Trust Bond Collateral for such purpose.


 






     39


     


    

 


(b)         If
an Event of Default under Section 5.01(g) shall have occurred and be continuing, the Indenture Trustee, for the
benefit of the Secured Parties, shall be entitled and empowered, to the extent permitted by applicable law, to institute or
participate in Proceedings necessary to compel performance of or to enforce the State Pledge and to collect any monetary
damages incurred by the Holders or the Indenture Trustee as a result of any such Event of Default, and may prosecute any such
Proceeding to final judgment or decree. Such remedy shall be the only remedy that the Indenture Trustee may exercise if the
only Event of Default that has occurred and is continuing is an Event of Default under Section 5.01(g).


 


(c)         
If the Indenture Trustee collects any money pursuant to this Article V, it shall pay out such money in accordance
with the priorities set forth in Section 8.02(e).


 


Section 5.05.     Optional
Preservation of the Collateral. If the Environmental Trust Bonds have been declared to be due and payable under Section
5.02 following an Event of Default and such declaration and its consequences have not been rescinded and annulled, the Indenture
Trustee may, but need not, elect to maintain possession of all or a portion of the Environmental Trust Bond Collateral. It is
the desire of the parties hereto and the Holders that there be at all times sufficient funds for the payment of principal of and
premium, if any, and interest on the Environmental Trust Bonds, and the Indenture Trustee shall take such desire into account
when determining whether or not to maintain possession of the Environmental Trust Bond Collateral. In determining whether to maintain
possession of the Environmental Trust Bond Collateral or sell or liquidate the same, the Indenture Trustee may, but need not,
obtain and conclusively rely upon an opinion of an Independent investment banking or accounting firm of national reputation as
to the feasibility of such proposed action and as to the sufficiency of the Environmental Trust Bond Collateral for such purpose.


 


Section 5.06.      Limitation
of Suits. No Holder of any Environmental Trust Bond shall have any right to institute any Proceeding, judicial or otherwise,
to avail itself of any remedies provided in the Statute or to avail itself of the right to foreclose on the Environmental Trust
Bond Collateral or otherwise enforce the Lien and the security interest on the Environmental Trust Bond Collateral with respect
to this Indenture and the Series Supplement, or for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless:


 


(a)         
such Holder previously has given written notice to the Indenture Trustee of a continuing Event of Default;


 


(b)         
the Holders of not less than a majority of the Outstanding Amount of the Environmental Trust Bonds have made written request
to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee
hereunder;


 


(c)         
such Holder or Holders have offered to the Indenture Trustee indemnity satisfactory to it against the costs, expenses and
liabilities to be incurred in complying with such request;


 


(d)         
the Indenture Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity has failed to
institute such Proceedings; and


 






     40


     


    

 


(e)          no
direction inconsistent with such written request has been given to the Indenture Trustee during such sixty-day period by the
Holders of a majority of the Outstanding Amount of the Environmental Trust Bonds; it being understood and intended that no
one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other Holders or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided.


 


In the event the Indenture Trustee shall receive
conflicting or inconsistent requests and indemnity from two or more groups of Holders, each representing less than a majority of
the Outstanding Amount of the Environmental Trust Bonds, the Indenture Trustee in its sole discretion may file a petition with
a court of competent jurisdiction to resolve such conflict or determine what action, if any, shall be taken, notwithstanding any
other provisions of this Indenture.


 


Section 5.07.     
Unconditional Rights of Holders To Receive Principal, Premium, if any, and Interest. Notwithstanding any other provisions
in this Indenture, the Holder of any Environmental Trust Bond shall have the right, which is absolute and unconditional, (a) to
receive payment of (i) the interest, if any, on such Environmental Trust Bond on the due dates thereof expressed in such Environmental
Trust Bond or in this Indenture or (ii) the unpaid principal, if any, of the Environmental Trust Bonds on the Final Maturity Date
therefor and (b) to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent
of such Holder.


 


Section 5.08.     
Restoration of Rights and Remedies. If the Indenture Trustee or any Holder has instituted any Proceeding to enforce
any right or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any reason or has been determined
adversely to the Indenture Trustee or to such Holder, then and in every such case the Issuer, the Indenture Trustee and the Holders
shall, subject to any determination in such Proceeding, be restored severally and respectively to their former positions hereunder,
and thereafter all rights and remedies of the Indenture Trustee and the Holders shall continue as though no such Proceeding had
been instituted.


 


Section 5.09.     
Rights and Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Indenture Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.


 


Section 5.10.     
Delay or Omission Not a Waiver. No delay or omission of the Indenture Trustee or any Holder to exercise any right
or remedy accruing upon any Default or Event of Default shall impair any such right or remedy or constitute a waiver of any such
Default or Event of Default or an acquiescence therein. Every right and remedy given by this Article V or by law to the
Indenture Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture
Trustee or by the Holders, as the case may be.


 






     41


     


    

 


Section 5.11.     
Control by Holders. The Holders of not less than a majority of the Outstanding Amount of the Environmental Trust
Bonds (or, if less than all Tranches are affected, the affected Tranche or Tranches) shall have the right to direct the time,
method and place of conducting any Proceeding for any remedy available to the Indenture Trustee with respect to the Environmental
Trust Bonds of such Tranche or Tranches or exercising any trust or power conferred on the Indenture Trustee with respect to such
Tranche or Tranches; provided, that:


 


(a)         
such direction shall not be in conflict with any rule of law or with this Indenture or the Series Supplement and shall not
involve the Indenture Trustee in any personal liability or expense;


 


(b)         
subject to other conditions specified in Section 5.04, any direction to the Indenture Trustee to sell or liquidate
any Environmental Trust Bond Collateral shall be by the Holders representing 100 percent of the Outstanding Amount of the Environmental
Trust Bonds as provided in Section 5.04;


 


(c)         
if the conditions set forth in Section 5.05 have been satisfied and the Indenture Trustee elects to retain the Environmental
Trust Bond Collateral pursuant to Section 5.05, then any direction to the Indenture Trustee by Holders representing less
than 100 percent of the Outstanding Amount of the Environmental Trust Bonds to sell or liquidate the Environmental Trust Bond Collateral
shall be of no force and effect; and


 


(d)          the
Indenture Trustee may take any other action deemed proper by the Indenture Trustee that is not inconsistent with such direction;


 


provided, however, that the
Indenture Trustee’s duties shall be subject to Section 6.01, and the Indenture Trustee need not take any action that
it determines might involve it in liability or might materially adversely affect the rights of any Holders not consenting to such
action. Furthermore and without limiting the foregoing, the Indenture Trustee shall not be required to take any action for which
it reasonably believes that it will not be indemnified to its satisfaction against any cost, expense or liabilities.


 


Section 5.12.     
Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Environmental Trust
Bonds as provided in Section 5.02, the Holders representing not less than a majority of the Outstanding Amount of the Environmental
Trust Bonds of an affected Tranche may waive any past Default or Event of Default and its consequences except a Default (a) in
payment of principal of or premium, if any, or interest on any of the Environmental Trust Bonds or (b) in respect of a covenant
or provision hereof which cannot be modified or amended without the consent of the Holder of each Environmental Trust Bond of all
Tranches affected. In the case of any such waiver, the Issuer, the Indenture Trustee and the Holders shall be restored to their
former positions and rights hereunder, respectively, but no such waiver shall extend to any subsequent or other Default or Event
of Default or impair any right consequent thereto.


 


Upon any such waiver, such Default shall
cease to exist and be deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be
deemed to have been cured and not to have occurred, for every purpose of this Indenture, but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right consequent thereto


 






     42


     


    

 


Section 5.13.     
Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Environmental Trust Bond by such
Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken,
suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against
any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 5.13 shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit
instituted by any Holder, or group of Holders, in each case holding in the aggregate more than ten (10) percent of the Outstanding
Amount of the Environmental Trust Bonds or (c) any suit instituted by any Holder for the enforcement of the payment of (i) interest
on any Environmental Trust Bond on or after the due dates expressed in such Environmental Trust Bond and in this Indenture or (ii)
the unpaid principal, if any, of any Environmental Trust Bond on or after the Final Maturity Date therefor.


 


Section 5.14.      
Waiver of Stay or Extension Laws. The Issuer 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 wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture;
and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted.


 


Section 5.15.     
Action on Environmental Trust Bonds. The Indenture Trustee’s right to seek and recover judgment on the Environmental
Trust Bonds or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the Lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Holders
shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under
such judgment upon any portion of the Environmental Trust Bond Collateral or any other assets of the Issuer.


 


ARTICLE
VI



THE INDENTURE TRUSTEE


 


Section 6.01.      
Duties of Indenture Trustee.


 


(a)         
If an Event of Default has occurred and is continuing, the Indenture Trustee shall exercise the rights and powers vested
in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under
the circumstances in the conduct of such person’s own affairs.


 






     43


     


    

 


(b)         
 Except during the continuance of an Event of Default:


 


(i)          
the Indenture Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture,
and no implied covenants or obligations shall be read into this Indenture against the Indenture Trustee; and


 


(ii)         
in the absence of bad faith on its part, the Indenture 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 Indenture Trustee and conforming
on their face to the requirements of this Indenture.


 


(c)         
The Indenture Trustee may not be relieved from liability for its own negligent action, its own bad faith, its own negligent
failure to act or its own willful misconduct, except that:


 


(i)           
this Section 6.01(c) does not limit the effect of Section 6.01(b);


 


(ii)         
the Indenture Trustee shall not be liable for any error of judgment made in good faith by the Indenture Trustee unless it
is proved that the Indenture Trustee was negligent in ascertaining the pertinent facts; and


 


(iii)        
the Indenture Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance
with a direction received by it hereunder.


 


(d)         
Every provision of this Indenture that in any way relates to the Indenture Trustee is subject to Section 6.01(a),
Section 6.01(b) and Section 6.01(c).

(g)         
No provision of this Indenture shall require the Indenture Trustee to expend or risk its own funds or otherwise incur financial
liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have
reasonable grounds to believe that repayments of such funds or indemnity satisfactory to it against such risk or liability is not
reasonably assured to it.


 


(h)          Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Indenture
Trustee shall be subject to the provisions of this Section 6.01 and to the provisions of the Trust Indenture Act.


 


(i)           In
the event that the Indenture Trustee is also acting as Paying Agent or Environmental Trust Bond Registrar hereunder, the protections
of this Article VI shall also be afforded to the Indenture Trustee in its capacity as Paying Agent or Environmental Trust
Bond Registrar.


 






     44


     


    

 



 


(j)            Except
for the express duties of the Indenture Trustee set forth in the Basic Documents, the Indenture Trustee shall have no obligation
to administer, service or collect Environmental Control Property or to maintain, monitor or otherwise supervise the administration,
servicing or collection of the Environmental Control Charges.


 


(k)           Under no circumstance shall the Indenture Trustee be

perform or to be responsible for the performance of any of the Servicer’s obligations under the Basic Documents.

with March 15, 2022, on or before March 15th of each fiscal year ending December 31, the Indenture Trustee shall (i) deliver to
the Issuer a report (in form and substance reasonably satisfactory to the Issuer and addressed to the Issuer and signed by an

of compliance made by the Indenture Trustee and delivered pursuant to Section 6.01(l)(i).


 


(m)         The
Indenture Trustee shall not be required to take any action it is directed to take under this Indenture if the Indenture Trustee
determines in good faith that the action so directed is inconsistent with the Indenture, any other Basic Document or Applicable
Law, or would involve the Indenture Trustee in personal liability.


 


(n)          The
Indenture Trustee shall not be responsible for special, indirect, punitive or consequential damages, except for its own willful
misconduct, negligence or bad faith.

no event shall the Indenture Trustee be liable for failure to perform its duties hereunder if such failure is a direct result of
another party’s failure to perform its obligations hereunder.


 


(p)          Any
discretion, permissive right or privilege of the Indenture Trustee hereunder shall not be deemed to be or otherwise construed as

Section 6.02.     
Rights of Indenture Trustee.


 


(a)          The
Indenture Trustee may conclusively rely and shall be fully protected in relying on any document (including electronic documents
and communications delivered in accordance with the terms of this Indenture) believed by it to be genuine and to have been signed
or presented by the proper person. The Indenture Trustee need not investigate any fact or matter stated in such document.


 


(b)          Before
the Indenture Trustee acts or refrains from acting, it may require and shall be entitled to receive an Officer’s Certificate
or an Opinion of Counsel of external counsel of the Issuer (at no cost or expense to the Indenture Trustee) that such action is
required or permitted hereunder. The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith
in reliance on such Officer’s Certificate or Opinion of Counsel.


 


(c)           The
Indenture Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through
agents or attorneys or a custodian or nominee, and the Indenture Trustee shall not be responsible for any misconduct or negligence
on the part of, or for the supervision of, any such agent, attorney, custodian or nominee appointed with due care by it hereunder.
The Indenture Trustee shall give prompt written notice to the Rating Agencies, of the appointment of any such agent, custodian
or nominee to whom it delegates any of its express duties under this Indenture; provided, that the Indenture Trustee shall
not be obligated to give such notice (i) if the Issuer or the Holders have directed the Indenture Trustee to appoint such agent,
custodian or nominee (in which event the Issuer shall give prompt notice to the Rating Agencies of any such direction) or (ii)
of the appointment of any agents, custodians or nominees made at any time that an Event of Default on account of non-payment of
principal or interest on the Environmental Trust Bonds or insolvency of the Issuer has occurred and is continuing.


 


(d)          The
Indenture Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized
or within its rights or powers; provided, however, that the Indenture Trustee’s conduct does not constitute
willful misconduct, negligence or bad faith.


 


(e)           The
Indenture Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Environmental Trust Bonds shall be full and complete authorization and protection from liability in respect
to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.


 


(f)           The
Indenture Trustee shall be under no obligation to (i) take any action or exercise any of the rights or powers vested in it by
this Indenture or any other Basic Document at the request or direction of any of the Holders pursuant to this Indenture or (ii)
to institute, conduct or defend any litigation hereunder or thereunder or in relation hereto or thereto or to investigate any
matter, at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture and the Series Supplement
or otherwise, unless it shall have grounds to believe in its discretion that security or indemnity against the costs, expenses
and liabilities which may be incurred therein or thereby is to its satisfaction assured to it.


 






     46


     


    

 


(g)          In
no event shall the Indenture Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder
arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages,
acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss
or malfunctions of utilities, communications or computer systems services, it being understood that the Indenture Trustee shall
use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable
under the circumstances.


 


(h)          The
Indenture Trustee shall not be deemed to have notice or knowledge of any Default or Event of Default unless a Responsible Officer
of the Indenture Trustee has actual knowledge thereof or the Indenture Trustee has received written notice thereof pursuant to
Section 10.04(a)(i).


 


Section 6.03.     
Individual Rights of Indenture Trustee. The Indenture Trustee in its individual or any other capacity may become
the owner or pledgee of Environmental Trust Bonds and may otherwise deal with the Issuer or its Affiliates with the same rights
it would have if it were not Indenture Trustee. Any Paying Agent, Environmental Trust Bond Registrar, co-registrar or co-paying
agent or agent appointed under Section 3.02 may do the same with like rights. However, the Indenture Trustee must comply
with Section 6.11 and Section 6.12.


 


Section 6.04.     
Indenture Trustee’s Disclaimer. The Indenture Trustee shall not be responsible for and makes no representation
(other than as set forth in Section 6.13) as to the validity or adequacy of this Indenture or the Environmental Trust Bonds,
it shall not be accountable for the Issuer’s use of the proceeds from the Environmental Trust Bonds, and it shall not be
responsible for any statement of the Issuer in this Indenture or in any document issued in connection with the sale of the Environmental
Trust Bonds or in the Environmental Trust Bonds other than the Indenture Trustee’s certificate of authentication. The Indenture
Trustee shall not be responsible for the form, character, genuineness, sufficiency, value or validity of any of the Environmental
Trust Bond Collateral, or for or in respect of the Environmental Trust Bonds (other than the certificate of authentication for
the Environmental Trust Bonds) or the Basic Documents, and the Indenture Trustee shall in no event assume or incur any liability,
duty or obligation to any Holder, other than as expressly provided in this Indenture. The Indenture Trustee shall not be liable
for the default or misconduct of the Issuer, the Seller or the Servicer under the Basic Documents or otherwise, and the Indenture
Trustee shall have no obligation or liability to perform the obligations of such Persons.


 


Section 6.05.      Notice
of Defaults. If a Default occurs and is continuing and if it is actually known to a Responsible Officer of the Indenture
Trustee, the Indenture Trustee shall mail to each Rating Agency and each Holder notice of the Default within ten (10)
Business Days after such Default was actually known to a Responsible Officer of the Indenture Trustee (provided that the
Indenture Trustee shall give the Rating Agencies prompt notice of any payment default in respect of the Environmental Trust
Bonds). Except in the case of a Default in payment of principal of and premium, if any, or interest on any Environmental
Trust Bond, the Indenture Trustee may withhold the notice if a Responsible Officer in good faith determines that prompt
notice of the Default is not likely to be material to Holders and the Default is likely to be cured and therefore that
withholding the notice is in the interests of Holders. Except for an Event of Default under Section 5.01(a) or Section
5.01(b) that occurs at a time when the Indenture Trustee is acting as the Paying Agent, and except as provided in the
first sentence of this Section 6.05, in no event shall the Indenture Trustee be deemed to have knowledge of a
Default.


 






     47


     


    

 


Section 6.06.     
Reports by Indenture Trustee to Holders.


 


(a)           So
long as Environmental Trust Bonds are Outstanding and the Indenture Trustee is the Environmental Trust Bond Registrar and Paying
Agent, upon the written request of any Holder or the Issuer, within the prescribed period of time for tax reporting purposes after
the end of each calendar year, the Indenture Trustee shall deliver to each relevant current or former Holder such information
in its possession as may be required to enable such Holder to prepare its U.S. federal income and any applicable local or State
tax returns. If the Environmental Trust Bond Registrar and Paying Agent is other than the Indenture Trustee, such Environmental
Trust Bond Registrar and Paying Agent, within the prescribed period of time for tax reporting purposes after the end of each calendar
year, shall deliver to each relevant current or former Holder such information in its possession as may be required to enable
such Holder to prepare its U.S. federal income and any applicable local or State tax returns.


 


(b)          On
or prior to each Payment Date or Special Payment Date therefor, the Indenture Trustee will deliver to each Holder of the Environmental
Trust Bonds on such Payment Date or Special Payment Date a statement as provided and prepared by the Servicer, which will include
(to the extent applicable) the following information (and any other information so specified in the Series Supplement) as to the
Environmental Trust Bonds with respect to such Payment Date or Special Payment Date or the period since the previous Payment Date,
as applicable:


 


(i)             the
amount of the payment to Holders allocable to principal, if any;


 


(ii)            the
amount of the payment to Holders allocable to interest;


 


(iii)           the
aggregate Outstanding Amount of the Environmental Trust Bonds, before and after giving effect to any payments allocated to principal
reported under Section 6.06(b)(i);


 


(iv)           the
difference, if any, between the amount specified in Section 6.06(b)(iii) and the Outstanding Amount specified in the related
Expected Amortization Schedule;


 


(v)            any
other transfers and payments to be made on such Payment Date or Special Payment Date, including amounts paid to the Indenture
Trustee and to the Servicer; and


 


(vi)           the
amounts on deposit in the Capital Subaccount and the Excess Funds Subaccount, after giving effect to the foregoing payments


 


(c)          The
Issuer shall send a copy of each of the Certificate of Compliance delivered to it pursuant to Section 3.03 of the Servicing
Agreement and the Annual Accountant’s Report delivered to it pursuant to Section 3.04 of the Servicing Agreement
to the Rating Agencies, the Indenture Trustee and to the Servicer for posting on the 17g-5 Website in accordance with Rule 17g-5
under the Exchange Act. A copy of such certificate and report may be obtained by any Holder by a request in writing to the Indenture
Trustee.


 






     48


     


    

 


(d)          The
Indenture Trustee may consult with counsel and the advice or opinion of such counsel with respect to legal matters relating to
this Indenture and the Environmental Trust Bonds shall be full and complete authorization and protection from liability with respect
to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.


 


Section 6.07.      Compensation
and Indemnity. The Issuer shall pay to the Indenture Trustee from time to time reasonable compensation for its services.
The Indenture Trustee’s compensation shall not, to the extent permitted by law, be limited by any law on compensation
of a trustee of an express trust. The Issuer shall reimburse the Indenture Trustee for all reasonable out-of-pocket expenses,
disbursements and advances incurred or made by it, including costs of collection, in addition to the compensation for its
services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Indenture
Trustee’s agents, counsel, accountants and experts. The Issuer shall indemnify and hold harmless the Indenture Trustee
and its officers, directors, employees and agents (each an “Indemnified Person”) against any and all cost,
damage, loss, liability, tax or expense (including reasonable attorneys’ fees and expenses, the fees of experts and
agents and any reasonable extraordinary out-of-pocket expenses) incurred by it in connection with the administration and the
enforcement of this Indenture, the Series Supplement and the other Basic Documents, including the costs and expenses of
defending themselves against any claim of liability in connection with the exercise of the Indenture Trustee’s rights,
powers and obligations under this Indenture, the Series Supplement and the other Basic Documents and the performance of its
duties hereunder and obligations under or pursuant to this Indenture, the Series Supplement and the other Basic Documents and
the costs of defending any claim or bringing any claim to enforce the Issuer’s indemnification obligations hereunder.
The Issuer shall not be required to indemnify the Indemnified Person for any amount paid or payable by such Indemnified
Person in the settlement of any action, proceeding or investigation without the prior written consent of the Issuer which
consent shall not be unreasonably withheld. Promptly after receipt by an Indemnified Person of notice of the commencement of
any action, proceeding or investigation, such Indemnified Person shall, if a claim in respect thereof is to be made against
the Issuer under this Section 6.07, notify the Issuer in writing of the commencement thereof. Failure by an
Indemnified Person to so notify the Issuer shall not relieve the Issuer from the obligation to indemnify and hold harmless
such Indemnified Person under this Section 6.07. With respect to any action, proceeding or investigation brought by a
third party for which indemnification may be sought under this Section 6.07, the Issuer shall be entitled to conduct
and control, at its expense and with counsel of its choosing that is reasonably satisfactory to such Indemnified Person, the
defense of any such action, proceeding or investigation (in which case the Issuer shall not thereafter be responsible for the
fees and expenses of any separate counsel retained by such Indemnified Person except as set forth below); provided that such
Indemnified Person shall have the right to participate in such action, proceeding or investigation through counsel chosen by
it and at its own expense. Notwithstanding the Issuer’s election to assume the defense of any action, proceeding or
investigation, such Indemnified Person shall have the right to employ separate counsel (including local counsel), and the
Issuer shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the defendants in any such action
include both the Indemnified Person and the Issuer and the Indemnified Person shall have reasonably concluded that there may
be legal defenses available to it that are different from or additional to those available to the Issuer, (ii) the Issuer
shall not have employed counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person within
a reasonable time after notice of the institution of such action or (iii) the Issuer shall authorize the Indemnified Person
to employ separate counsel at the expense of the Issuer. Notwithstanding the foregoing, the Issuer shall not be obligated to
pay for the fees, costs and expenses of more than one separate counsel for the Indemnified Person other than one local
counsel, if appropriate. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense
incurred by the Indenture Trustee through the Indemnified Person’s own willful misconduct, negligence or bad faith. The
rights of the Indenture Trustee set forth in this Section 6.07 are subject to and limited by the priority of payments
set forth in Section 8.02(e).


 






     49


     


    

 


The payment obligations to the Indenture Trustee
pursuant to this Section 6.07 shall survive the discharge of this Indenture and the Series Supplement or the earlier resignation
or removal of the Indenture Trustee. When the Indenture Trustee incurs expenses after the occurrence of a Default specified in
Section 5.01(e) or Section 5.01(f) with respect to the Issuer, the expenses are intended to constitute expenses of
administration under the Bankruptcy Code or any other applicable U.S. federal or State bankruptcy, insolvency or similar law


 


Section 6.08.     
Replacement of Indenture Trustee and Securities Intermediary.


 


(a)           The
Indenture Trustee (or any other Eligible Institution in any capacity under the Indenture) may resign at any time upon thirty (30)
days’ prior written notice to the Issuer subject to Section 6.08(c). The Holders of a majority of the Outstanding
Amount of the Environmental Trust Bonds may remove the Indenture Trustee (or any other Eligible Institution in any capacity under
the Indenture) with thirty (30) days’ prior written notice by so notifying the Indenture Trustee (or such other Eligible
Institution) and may appoint a successor Indenture Trustee (or successor Eligible Institution in the applicable capacity). The
Issuer shall remove the Indenture Trustee if:


 


(i)             the
Indenture Trustee fails to comply with Section 6.11;


 


(ii)            the
Indenture Trustee is adjudged a bankrupt or insolvent;


 


(iii)           a
receiver or other public officer takes charge of the Indenture Trustee or its property;


 


(iv)           the
Indenture Trustee otherwise becomes incapable of acting; or


 


(v)            the
Indenture Trustee fails to provide to the Issuer any information reasonably requested by the Issuer pertaining to the Indenture
Trustee and necessary for the Issuer or the Sponsor to comply with its respective reporting obligations under the Exchange Act
and Regulation AB and such failure is not resolved to the Issuer’s and the Indenture Trustee’s mutual satisfaction
within a reasonable period of time.


 






     50


     


    

 


Any removal or resignation of the Indenture
Trustee shall also constitute a removal or resignation of the Securities Intermediary. The Issuer shall remove any person (other
than the Indenture Trustee) acting in any capacity under the Indenture that fails to constitute an Eligible Institution with 30
days’ prior notice.


 


(b)          If
the Indenture Trustee gives notice of resignation or is removed or if a vacancy exists in the office of Indenture Trustee for
any reason (the Indenture Trustee in such event being referred to herein as the retiring Indenture Trustee), the Issuer shall
promptly appoint a successor Indenture Trustee and Securities Intermediary. If any person (other than the Indenture Trustee) acting
in any capacity under the Indenture as an Eligible Institution is removed, fails to constitute an Eligible Institution or if a
vacancy exists in any such capacity for any reason, the Issuer shall promptly appoint a successor to such capacity that constitutes
an Eligible Institution.


 


(c)           A
successor Indenture Trustee (or any other successor Eligible Institution) shall deliver a written acceptance of its appointment
as the Indenture Trustee and as the Securities Intermediary (or any such other capacity) to the retiring Indenture Trustee (or
any such other capacity) and to the Issuer. Thereupon the resignation or removal of the retiring Indenture Trustee (or any such
other Person) shall become effective, and the successor Indenture Trustee (or such other successor Eligible Institution) shall
have all the rights, powers and duties of the Indenture Trustee and Securities Intermediary (or such other Eligible Institution),
as applicable, under this Indenture and the other Basic Documents. No resignation or removal of the Indenture Trustee (or any
other Person acting as an Eligible Institution) pursuant to this Section 6.08 shall become effective until acceptance of
the appointment by a successor Indenture Trustee having the qualifications set forth in Section 6.11 (or acceptance of
the appointment by such other successor Eligible Institution). Notice of any such appointment shall be promptly given to each
Rating Agency by the successor Indenture Trustee. The successor Indenture Trustee shall mail a notice of its succession (or the
succession of any other Eligible Institution) to Holders. The retiring Indenture Trustee shall promptly transfer all property
held by it as Indenture Trustee to the successor Indenture Trustee. The retiring Eligible Institution shall promptly transfer
all property held by it in its capacity hereunder to the successor Eligible Institution).


 


(d)          If
a successor Indenture Trustee (or other successor Eligible Institution) does not take office within sixty (60) days after the
retiring Indenture Trustee (or other retiring Eligible Institution) resigns or is removed, the retiring Indenture Trustee (or
other retiring Eligible Institution), the Issuer or the Holders of a majority in Outstanding Amount of the Environmental Trust
Bonds may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee (or other successor
Eligible Institution).


 


(e)           If
the Indenture Trustee fails to comply with Section 6.11, any Holder may petition any court of competent jurisdiction for
the removal of the Indenture Trustee and the appointment of a successor Indenture Trustee.


 


(f)           Notwithstanding
the replacement of the Indenture Trustee pursuant to this Section 6.08, the Issuer’s obligations under Section
6.07 shall continue for the benefit of the retiring Indenture Trustee.


 






     51


     


    

 


Section 6.09.     Successor Indenture Trustee by Merger. If the Indenture Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving
or transferee corporation or banking association without any further act shall be the successor Indenture Trustee; provided,
however, that, if such successor Indenture Trustee is not eligible under Section 6.11, then the successor Indenture
Trustee shall be replaced in accordance with Section 6.08. Notice of any such event shall be promptly given to each Rating
Agency by the successor Indenture Trustee.


 


In case at the time such successor or successors
by merger, conversion, consolidation or transfer shall succeed to the trusts created by this Indenture any of the Environmental
Trust Bonds shall have been authenticated but not delivered, any such successor to the Indenture Trustee may adopt the certificate
of authentication of any predecessor trustee and deliver the Environmental Trust Bonds so authenticated; and, in case at that time
any of the Environmental Trust Bonds shall not have been authenticated, any successor to the Indenture Trustee may authenticate
the Environmental Trust Bonds either in the name of any predecessor hereunder or in the name of the successor to the Indenture
Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Environmental Trust Bonds
or in this Indenture provided that the certificate of the Indenture Trustee shall have.


 


Section 6.10.    
Appointment of Co-Trustee or Separate Trustee.


 


(a)           Notwithstanding
any other provisions of this Indenture, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which
any part of the trust created by this Indenture or the Environmental Trust Bond Collateral may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee
or co-trustees, or separate trustee or separate trustees, of all or any part of the trust created by this Indenture or the Environmental
Trust Bond Collateral, and to vest in such Person or Persons, in such capacity and for the benefit of the Secured Parties, such
title to the Environmental Trust Bond Collateral, or any part hereof, and, subject to the other provisions of this Section
6.10, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section
6.11 and no notice to Holders of the appointment of any co-trustee or separate trustee shall be required under Section
6.08. Notice of any such appointment shall be promptly given to each Rating Agency by the Indenture Trustee.


 


(b)          Every
separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions
and conditions:


 


(i)             all
rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred or imposed upon and
exercised or performed by the Indenture Trustee and such separate trustee or co-trustee jointly (it being understood that such
separate trustee or co-trustee is not authorized to act separately without the Indenture Trustee joining in such act), except
to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Indenture Trustee
shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including
the holding of title to the Environmental Trust Bond Collateral or any portion thereof in any such jurisdiction) shall be exercised
and performed singly by such separate trustee or co-trustee, but solely at the direction of the Indenture Trustee;


 






     52


     


    

 


(ii)            no
trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and


 


(iii)           the
Indenture Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee.


 


(c)          Any
notice, request or other writing given to the Indenture Trustee shall be deemed to have been given to each of the then-separate
trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee
shall refer to this Indenture and the conditions of this Article VI. Each separate trustee and co-trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly
with the Indenture Trustee or separately, as may be provided therein, subject to all the provisions of this Indenture, specifically
including every provision of this Indenture relating to the conduct of, affecting the liability of, or affording protection to,
the Indenture Trustee. Every such instrument shall be filed with the Indenture Trustee.


 


(d)          Any
separate trustee or co-trustee may at any time constitute the Indenture Trustee, its agent or its attorney-in-fact with full power
and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Indenture on its behalf and
in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the Indenture Trustee, to the extent permitted by law,
without the appointment of a new or successor trustee.


 


Section 6.11.     Eligibility;

including the optional provision permitted by the second sentence of Section 310(b)(9) of the Trust Indenture Act; provided, however,
that there shall be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act any indenture or indentures under
which other securities of the Issuer are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the
Trust Indenture Act are met.


 


Section 6.12.     Preferential
Collection of Claims Against Issuer. The Indenture Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding
any creditor relationship listed in Section 311(b) of the Trust Indenture Act. An Indenture Trustee who has resigned or been removed

the Issuer in accordance with Section 3.04(a) of the Servicing Agreement. In the event such firm requires the Indenture
Trustee to agree to the procedures performed by such firm, the Issuer shall direct the Indenture Trustee in writing to so agree;

ACCOUNTS, DISBURSEMENTS AND RELEASES


 


Section 8.01.     Collection
of Money. Except as otherwise expressly provided herein, the Indenture Trustee may demand payment or delivery of, and shall
receive and collect, directly and without intervention or assistance of any fiscal agent or other intermediary, all money and
other property payable to or receivable by the Indenture Trustee pursuant to this Indenture and the other Basic Documents. The
Indenture Trustee shall apply all such money received by it as provided in this Indenture. Except as otherwise expressly provided
in this Indenture, if any default occurs in the making of any payment or performance under any agreement or instrument that is
part of the Environmental Trust Bond Collateral, the Indenture Trustee may take such action as may be appropriate to enforce such
payment or performance, subject to Article VI, including the institution and prosecution of appropriate Proceedings. Any
such action shall be without prejudice to any right to claim a Default or Event of Default under this Indenture and any right
to proceed thereafter as provided in Article V.


 


Section 8.02.     
Collection Account.


 


(a)          Prior
to the Closing Date, the Issuer shall open or cause to be opened with the Securities Intermediary located at the Indenture
Trustee’s office located at the Corporate Trust Office, or at another Eligible Institution, one or more segregated
trust accounts in the Indenture Trustee’s name for the deposit of Estimated EC Charge Collections, EC Charge
Collections and all other amounts received with respect to the Environmental Trust Bond Collateral (the “Collection
Account”). The Collection Account will consist of three subaccounts: a general subaccount (the “General
Subaccount”); an excess funds subaccount (the “Excess Funds Subaccount”); and a capital
subaccount (the “Capital Subaccount” and, together with the General Subaccount and the Excess Funds
Subaccount, the “Subaccounts”). For administrative purposes, the Subaccounts may be established by the
Securities Intermediary as separate accounts. Such separate accounts will be recognized individually as a Subaccount and
collectively as the “Collection Account.” Prior to or concurrently with the issuance of the Environmental Trust
Bonds, the Member shall deposit into the Capital Subaccount an amount equal to the Required Capital Level. All amounts in the
Collection Account not allocated to any other subaccount shall be allocated to the General Subaccount. Prior to the Initial
Payment Date, all amounts in the Collection Account (other than funds deposited into the Capital Subaccount up to the
Required Capital Level) shall be allocated to the General Subaccount. All references to the Collection Account shall be
deemed to include reference to all subaccounts contained therein. Withdrawals from and deposits to each of the foregoing
subaccounts of the Collection Account shall be made as set forth in Section 8.02(d) and Section 8.02(e). The
Collection Account shall at all times be maintained in an Eligible Account and will be under the sole dominion and exclusive
control of the Indenture Trustee, through the Securities Intermediary, and only the Indenture Trustee shall have access to
the Collection Account for the purpose of making deposits in and withdrawals from the Collection Account in accordance with
this Indenture. Funds in the Collection Account shall not be commingled with any other moneys. All moneys deposited from time
to time in the Collection Account, all deposits therein pursuant to this Indenture and all investments made in Eligible
Investments as directed in writing by the Issuer with such moneys, including all income or other gain from such investments,
shall be held by the Securities Intermediary in the Collection Account as part of the Environmental Trust Bond Collateral as
herein provided. The Securities Intermediary shall have no liability in respect of losses incurred as a result of the
liquidation of any Eligible Investment prior to its stated maturity or its date of redemption or the failure of the Issuer or
the Servicer to provide timely written investment direction.


 






     57


     


    

 


(b)          The
Securities Intermediary hereby confirms that (i) the Collection Account is, or at inception will be established as, a “securities
account” as such term is defined in Section 8-501(a) of the UCC, (ii) it is a “securities intermediary” (as
such term is defined in Section 8-102(a)(14) of the UCC) and is acting in such capacity with respect to such accounts, (iii) the
Indenture Trustee for the benefit of the Secured Parties is the sole “entitlement holder” (as such term is defined
in Section 8-102(a)(7) of the UCC) with respect to such accounts and (iv) no other Person shall have the right to give “entitlement
orders” (as such term is defined in Section 8-102(a)(8)) with respect to such accounts. The Securities Intermediary hereby
further agrees that each item of property (whether investment property, financial asset, security, instrument or cash) received
by it will be credited to the Collection Account. Such property, other than cash, shall be treated by it as a “financial
asset” within the meaning of Section 8-102(a)(9) of the UCC. The Indenture Trustee shall hold any Environmental Trust Bond
Collateral consisting of money in the Collection Account and hereby confirms that for such purpose, the Collection Account is
a “deposit account” within the meaning of Section 9-102(a)(29) of the UCC. The Indenture Trustee further confirms
that for purposes of perfecting the security interest in such deposit account, it shall act as the “bank” within the
meaning of Section 9-102(a)(8) of the UCC. Notwithstanding anything to the contrary, the State of New York shall be deemed to
be the jurisdiction of the Securities Intermediary for purposes of Section 8-110(e) of the UCC and of the Indenture Trustee acting
as the “bank” for purposes of Section 9-304(a) of the UCC, and the Collection Account (as well as the securities entitlements
related thereto) shall be governed by the laws of the State of New York. The Securities Intermediary represents and agrees that
(i) the “account agreement” (within the meaning of the Hague Securities Convention establishing the Collection Account
is governed by the law of the State of New York and that the law of the State of New York shall govern all issues specified in
Article 2(1) of the Hague Securities Convention and (ii) at the time of entry of such account agreement, the Securities Intermediary
had one or more offices (within the meaning of the Hague Securities Convention) in the United States of America which satisfies
the criteria provided in Article 4(1)(a) or (b) of the Hague Securities Convention.


 


(c)          The
Indenture Trustee shall have sole dominion and exclusive control over all moneys in the Collection Account through the Securities
Intermediary and shall apply such amounts therein as provided in this Section 8.02.


 


(d)          Estimated
EC Charge Collections and EC Charge Collections shall be deposited in the General Subaccount as provided in Section 6.11
of the Servicing Agreement. All deposits to and withdrawals from the Collection Account, all allocations to the subaccounts of
the Collection Account and any amounts to be paid to the Servicer under Section 8.02(e) shall be made by the Indenture
Trustee in accordance with the written instructions provided by the Servicer in the Monthly Servicer’s Certificate, the
Semi-Annual Servicer’s Certificate or upon other written notice provided by the Servicer pursuant to Section 6.11(a)
of the Servicing Agreement, as applicable.


 


(e)          On
each Payment Date, the Indenture Trustee shall apply all amounts on deposit in the Collection Account, including all Investment
Earnings thereon, to pay the following amounts, in accordance with the Semi-Annual Servicer’s Certificate, in the following
priority:


 


(i)             all
amounts owed by the Issuer to the Indenture Trustee (including legal fees and expenses and outstanding indemnity amounts) shall
be paid to the Indenture Trustee (subject to Section 6.07) in an amount not to exceed the amount set forth in the Series
Supplement;


 


(ii)            the
Servicing Fee with respect to such Payment Date and all unpaid Servicing Fees for prior Payment Dates shall be paid to the Servicer;


 


(iii)           the
Administration Fee for such Payment Date shall be paid to the Administrator and the Independent Manager Fee for such Payment Date
shall be paid to the Independent Manager, and in each case with any unpaid Administration Fees or Independent Manager Fees from
prior Payment Dates;


 


(iv)           all
other ordinary and periodic Operating Expenses for such Payment Date not described above shall be paid to the parties to which
such Operating Expenses are owed;


 


(v)            Periodic
Interest for such Payment Date, including any overdue Periodic Interest (together with, to the extent lawful, interest on such
overdue Periodic Interest at the applicable Environmental Trust Bond Interest Rate), with respect to the Environmental Trust Bonds
shall be paid to the Holders of Environmental Trust Bonds;


 


(vi)           principal
due and payable on the Environmental Trust Bonds as a result of an acceleration upon an Event of Default or on the Final Maturity
Date of the Environmental Trust Bonds shall be paid to the Holders of Environmental Trust Bonds;


 


(vii)          Periodic
Principal for such Payment Date, including any overdue Periodic Principal, with respect to the Environmental Trust Bonds shall
be paid to the Holders of Environmental Trust Bonds, pro rata if there is a deficiency;


 


(viii)         any
other unpaid Operating Expenses (including fees, expenses and indemnity amounts owed to the Indenture Trustee but unpaid due to
the limitation in Section 8.02(e)(i)) and any remaining amounts owed pursuant to the Basic Documents shall be paid the
parties to which such Operating Expenses or remaining amounts are owed;


 


(ix)            replenishment
of the amount, if any, by which the Required Capital Level exceeds the amount in the Capital Subaccount as of such Payment Date
shall be allocated to the Capital Subaccount;


 






     58


     


    

 



 


(x)              the Return on Invested Capital then due and payable, and any related taxes thereon, shall be paid to Wisconsin Electric;


 


(xi)             the
balance, if any, shall be allocated to the Excess Funds Subaccount for distribution on subsequent Payment Dates; and


 


(xii)            after
the principal of and premium, if any, and interest on all of the Environmental Trust Bonds, and all of the other foregoing amounts
have been paid in full, including, without limitation, amounts due and payable to the Indenture Trustee under Section 6.07
or otherwise, the balance (including all amounts then held in the Capital Subaccount and the Excess Funds Subaccount), if
any, shall be paid to the Issuer, free from the Lien of this Indenture and the Series Supplement.


 


All payments to the Holders of the Environmental
Trust Bonds pursuant to Section 8.02(e)(v), Section 8.02(e)(vi) and Section 8.02(e)(vii) shall be made to
such Holders pro rata based on the respective amounts of interest and/or principal owed, unless, in the case of Environmental Trust
Bonds comprised of two or more Tranches, the Series Supplement provides otherwise. Payments in respect of principal of and premium,
if any, and interest on any Tranche of Environmental Trust Bonds will be made on a pro rata basis among all the Holders of such
Tranche. In the case of an Event of Default, then, in accordance with Section 5.04(c), in respect of any application of
moneys pursuant to Section 8.02(e)(v) or Section 8.02(e)(vi), moneys will be applied pursuant to Section 8.02(e)(v)
and Section 8.02(e)(vi), as the case may be, in such order, on a pro rata basis, based upon the interest or the principal
owed.


 


(f)               
If on any Payment Date, or, for any amounts payable under Section 8.02(e)(i), Section 8.02(e)(ii), Section
8.02(e)(iii) and Section 8.02(e)(iv), on any Business Day, funds on deposit in the General Subaccount are insufficient
to make the payments contemplated by Section 8.02(e)(i), Section 8.02(e)(ii), Section 8.02(e)(iii), Section
8.02(e)(iv), Section 8.02(e)(v), Section 8.02(e)(vi), Section 8.02(e)(vii), and Section 8.02(e)(viii),
the Indenture Trustee shall (i) first, draw from amounts on deposit in the Excess Funds Subaccount, and (ii) second,
draw from amounts on deposit in the Capital Subaccount, in each case, up to the amount of such shortfall in order to make the payments
contemplated by Section 8.02(e)(i), Section 8.02(e)(ii), Section 8.02(e)(iii), Section 8.02(e)(iv),
Section 8.02(e)(v), Section 8.02(e)(vi), Section 8.02(e)(vii) and Section 8.02(e)(viii). In addition,
if on any Payment Date funds on deposit in the General Subaccount are insufficient to make the allocations contemplated by Section
8.02(e)(ix), the Indenture Trustee shall draw from amounts on deposit in the Excess Funds Subaccount to make such allocations
to the Capital Subaccount.


 


(g)               On
any Business Day upon which the Indenture Trustee receives a written request from the Administrator stating that any Operating
Expense payable by the Issuer (but only as described in Section 8.02(e)(i), Section 8.02(e)(ii), Section 8.02(e)(iii)
and Section 8.02(e)(iv)) will become due and payable prior to the next Payment Date, and setting forth the amount and
nature of such Operating Expense, as well as any supporting documentation that the Indenture Trustee may reasonably request, the
Indenture Trustee, upon receipt of such information, will make payment of such Operating Expenses on or before the date such payment
is due from amounts on deposit in the General Subaccount, the Excess Funds Subaccount and the Capital Subaccount, in that order
and only to the extent required to make such payment.

Section 8.03.     
General Provisions Regarding the Collection Account.


 


(a)               So
long as no Default or Event of Default shall have occurred and be continuing, all or a portion of the funds in the Collection
Account shall be invested in Eligible Investments and reinvested by the Indenture Trustee upon Issuer Order; provided,
however, that such Eligible Investments shall not mature or be redeemed later than the Business Day prior to the next Payment
Date or Special Payment Date, if applicable, for the Environmental Trust Bonds. All income or other gain from investments of moneys
deposited in the Collection Account shall be deposited by the Indenture Trustee in such Collection Account, and any loss resulting
from such investments shall be charged to the Collection Account. The Issuer will not direct the Indenture Trustee to make any
investment of any funds or to sell any investment held in the Collection Account unless the security interest Granted and perfected
in such account will continue to be perfected in such investment or the proceeds of such sale, in either case without any further
action by any Person, and, in connection with any direction to the Indenture Trustee to make any such investment or sale, if requested
by the Indenture Trustee, the Issuer shall deliver to the Indenture Trustee an Opinion of Counsel of external counsel of the Issuer
(at the Issuer’s cost and expense) to such effect. In no event shall the Indenture Trustee be liable for the selection of
Eligible Investments or for investment losses incurred thereon. The Indenture Trustee shall have no liability in respect of losses
incurred as a result of the liquidation of any Eligible Investment prior to its stated maturity or its date of redemption or the
failure of the Issuer or the Servicer to provide timely written investment direction. The Indenture Trustee shall have no obligation
to invest or reinvest any amounts held hereunder in the absence of written investment direction pursuant to an Issuer Order.


 


(b)               Subject
to Section 6.01(c), the Indenture Trustee shall not in any way be held liable by reason of any insufficiency in the Collection
Account resulting from any loss on any Eligible Investment included therein except for losses attributable to the Indenture Trustee’s
failure to make payments on such Eligible Investments issued by the Indenture Trustee, in its commercial capacity as principal
obligor and not as trustee, in accordance with their terms.


 


(c)              
If (i) the Issuer shall have failed to give written investment directions for any funds on deposit in the Collection Account
to the Indenture Trustee by 11:00 a.m. New York City time (or such other time as may be agreed by the Issuer and Indenture Trustee)
on any Business Day or (ii) a Default or Event of Default shall have occurred and be continuing with respect to the Environmental
Trust Bonds but the Environmental Trust Bonds shall not have been declared due and payable pursuant to Section 5.02, then
the Indenture Trustee shall, to the fullest extent practicable, invest and reinvest funds in such Collection Account in Eligible
Investments specified in the most recent written investment directions delivered by the Issuer to the Indenture Trustee; provided,
that if the Issuer has never delivered written investment directions to the Indenture Trustee, the Indenture Trustee shall not
invest or reinvest such funds in any investments.


 


(d)              
The parties hereto acknowledge that the Servicer may, pursuant to the Servicing Agreement, select Eligible Investments on
behalf of the Issuer.


 


(e)               Except
as otherwise provided hereunder or agreed in writing among the parties hereto, the Issuer shall retain the authority to
institute, participate and join in any plan of reorganization, readjustment, merger or consolidation with respect to the
issuer of any Eligible Investments held hereunder, and, in general, to exercise each and every other power or right with
respect to each such asset or investment as Persons generally have and enjoy with respect to their own assets and investment,
including power to vote upon any Eligible Investments.

Section 8.04.     
Release of Environmental Trust Bond Collateral.


 


(a)              
So long as the Issuer is not in default hereunder and no Default hereunder would occur as a result of such action, the Issuer,
through the Servicer, may collect, sell or otherwise dispose of written-off receivables relating to any Environmental Trust Bond
Collateral, at any time and from time to time in the ordinary course of business, without any notice to, or release or consent
by, the Indenture Trustee, but only as and to the extent permitted by the Basic Documents; provided, however, that
any and all proceeds of such dispositions shall become Environmental Trust Bond Collateral and be deposited to the General Subaccount
immediately upon receipt thereof by the Issuer or any other Person, including the Servicer. Without limiting the foregoing, the
Servicer, may, at any time and from time to time without any notice to, or release or consent by, the Indenture Trustee, sell or
otherwise dispose of any Environmental Trust Bond Collateral previously written-off as a defaulted or uncollectible account in
accordance with the terms of the Servicing Agreement and the requirements of the proviso in the immediately preceding sentence.


 


(b)               The
Indenture Trustee may, and when required by the provisions of this Indenture shall, execute instruments to release property from
the Lien of this Indenture, or convey the Indenture Trustee’s interest in the same, in a manner and under circumstances
that are not inconsistent with the provisions of this Indenture. No party relying upon an instrument executed by the Indenture
Trustee as provided in this Article VIII shall be bound to ascertain the Indenture Trustee’s authority, inquire into
the satisfaction of any conditions precedent or see to the application of any moneys. The Indenture Trustee shall release property
from the Lien of this Indenture pursuant to this Section 8.04(b) only upon receipt of an Issuer Request accompanied by
an Officer’s Certificate, an Opinion of Counsel of external counsel of the Issuer (at the Issuer’s cost and expense)
and (if required by the Trust Indenture Act) Independent Certificates in accordance with Section 314(c) of the Trust Indenture
Act and Section 314(d)(1) of the Trust Indenture Act meeting the applicable requirements of Section 10.01.


 


(c)              
The Indenture Trustee shall, at such time as there are no Environmental Trust Bonds Outstanding and all sums payable to
the Indenture Trustee pursuant to Section 6.07 or otherwise have been paid, release any remaining portion of the Environmental
Trust Bond Collateral that secured the Environmental Trust Bonds from the Lien of this Indenture and release to the Issuer or any
other Person entitled thereto any funds or investments then on deposit in or credited to the Collection Account.


 


Section 8.05.      Opinion
of Counsel. The Indenture Trustee shall receive at least seven (7) days’ notice when requested by the Issuer to
take any action pursuant to Section 8.04, accompanied by copies of any instruments involved, and the Indenture Trustee
shall also require, as a condition to such action, an Opinion of Counsel of external counsel of the Issuer, in form and
substance satisfactory to the Indenture Trustee, stating the legal effect of any such action, outlining the steps required to
complete the same, and concluding that all conditions precedent to the taking of such action have been complied with and such
action will not materially and adversely impair the perfection or priority of the remaining security for the Environmental
Trust Bonds or the rights of the Holders in contravention of the provisions of this Indenture and the Series Supplement; provided, however,
that such Opinion of Counsel shall not be required to express an opinion as to the fair value of the Environmental Trust Bond
Collateral. Counsel rendering any such opinion may rely, without independent investigation, on the accuracy and validity of
any certificate or other instrument delivered to the Indenture Trustee in connection with any such action.


 






     61


     


    

 


Section 8.06.     Reports
by Independent Registered Public Accountants. As of the Closing Date, the Issuer shall appoint a firm of Independent registered
public accountants of recognized national reputation for purposes of preparing and delivering the reports or certificates of such
accountants required by this Indenture and the Series Supplement. In the event such firm requires the Indenture Trustee to agree
to the procedures performed by such firm, the Issuer shall direct the Indenture Trustee in writing to so agree, it being understood
and agreed that the Indenture Trustee will deliver such letter of agreement in conclusive reliance upon the direction of the Issuer,
and the Indenture Trustee makes no independent inquiry or investigation to, and shall have no obligation or liability in respect
of, the sufficiency, validity or correctness of such procedures. Upon any resignation by, or termination by the Issuer of, such
firm, the Issuer shall provide written notice thereof to the Indenture Trustee and shall promptly appoint a successor thereto
that shall also be a firm of Independent registered public accountants of recognized national reputation. If the Issuer shall
fail to appoint a successor to a firm of Independent registered public accountants that has resigned or been terminated within
fifteen (15) days after such resignation or termination, the Indenture Trustee shall promptly notify the Issuer of such failure
in writing. If the Issuer shall not have appointed a successor within ten (10) days thereafter, the Indenture Trustee shall promptly
appoint a successor firm of Independent registered public accountants of recognized national reputation; provided, that
the Indenture Trustee shall have no liability with respect to such appointment. The fees of such Independent registered public
accountants and its successor shall be payable by the Issuer as an Operating Expense.

The Indenture Trustee is hereby authorized
to join in the execution of any such supplemental indenture and to make any further appropriate agreements and stipulations that
may be therein contained.


 


(b)              
Subject to paragraph (c) of this Section 9.01, the Issuer and the Indenture Trustee, when authorized by an Issuer Order,

Section 9.02.      Supplemental
Indentures with Consent of Holders. Subject to paragraph (c) of Section 9.01, the Issuer and the Indenture Trustee, when authorized
by an Issuer Order, also may, with prior notice to the Rating Agencies and with the consent of the Holders of not less than a

delivered to the Issuer and the Indenture Trustee, enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture or of modifying in
any manner the rights of the Holders of the Environmental Trust Bonds under this Indenture; provided, however, that

the provisions of this Indenture and the Series Supplement relating to the application of collections on, or the proceeds of the
sale of, the Environmental Trust Bond Collateral to payment of principal of or premium, if any, or interest on the Environmental
Trust Bonds, or change any place of payment where, or the coin or currency in which, any Environmental Trust Bond or the interest
thereon is payable;


 






     64


     


    

 


(iii)            
reduce the percentage of the Outstanding Amount of the Environmental Trust Bonds or of a Tranche thereof, the consent of
the Holders of which is required for any such supplemental indenture, or the consent of the Holders of which is required for any
waiver of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences provided for
in this Indenture;


 


(iv)            reduce
the percentage of the Outstanding Amount of the Environmental Trust Bonds required to direct the Indenture Trustee to direct the

those provisions of this Indenture or the other Basic Documents referenced in this Section 9.02 cannot be modified or waived
without the consent of the Holder of each Outstanding Environmental Trust Bond affected thereby;


 


(vi)            modify any of the provisions of this Indenture in such manner as to affect the calculation of the amount of any payment
of interest, principal or premium, if any, due on any Environmental Trust Bond on any Payment Date (including the calculation of
any of the individual components of such calculation) or change the Expected Amortization Schedule or Final Maturity Date of any
Tranche of Environmental Trust Bonds;


 


(vii)         
decrease the Required Capital Level;


 


(viii)         
permit the creation of any Lien ranking prior to or on a parity with the Lien of this Indenture with respect to any part

Indenture on any property at any time subject hereto or deprive the Holder of any Environmental Trust Bond of the security provided
by the Lien of this Indenture;


 


(ix)             cause
any material adverse U.S. federal income tax consequence to the Seller, the Issuer, the Managers, the Indenture Trustee or the
then-existing Holders; or


 


(x)              impair
the right to institute suit for the enforcement of the provisions of this Indenture regarding payment or application of funds.


 


It shall not be necessary for any Act of Holders
under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient
if such Act shall approve the substance thereof.


 


Promptly after the execution by the
Issuer and the Indenture Trustee of any supplemental indenture pursuant to this Section 9.02, the Issuer shall mail to
the Rating Agencies a copy of such supplemental indenture and to the Holders of the Environmental Trust Bonds to which such
supplemental indenture relates either a copy of such supplemental indenture or a notice setting forth in general terms the
substance of such supplemental indenture. Any failure of the Issuer to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental indenture.

Section 10.01. 
Compliance Certificates and Opinions, etc.


 


(a)               Upon
any application or request by the Issuer to the Indenture Trustee to take any action under any provision of this Indenture,
the Issuer shall furnish to the Indenture Trustee (i) an Officer’s Certificate stating that all conditions precedent,

any such application or request as to which the furnishing of such documents is specifically required by any provision of
this Indenture, no additional certificate or opinion need be furnished.


 






     66


     


    

 


Every certificate or opinion with respect
to compliance with a condition or covenant provided for in this Indenture shall include:


 


(i)                 a
statement that each signatory of such certificate or opinion has read or has caused to be read such covenant or condition and

a statement that, in the opinion of each such signatory, such signatory has made such examination or investigation as is
necessary to enable such signatory to express an informed opinion as to whether or not such covenant or condition has been complied
with; and


 


(iv)              
a statement as to whether, in the opinion of each such signatory, such condition or covenant has been complied with.


 


(b)              
Prior to the deposit of any Environmental Trust Bond Collateral or other property or securities with the Indenture Trustee
that is to be made the basis for the release of any property or securities subject to the Lien of this Indenture, the Issuer shall,
in addition to any obligation imposed in Section 10.01(a) or elsewhere in this Indenture, furnish to the Indenture Trustee
an Officer’s Certificate certifying or stating the opinion of each person signing such certificate as to the fair value (within
ninety (90) days of such deposit) to the Issuer of the Environmental Trust Bond Collateral or other property or securities to be
so deposited.


 


(c)              
Whenever the Issuer is required to furnish to the Indenture Trustee an Officer’s Certificate certifying or stating
the opinion of any signer thereof as to the matters described in Section 10.01(b), the Issuer shall also deliver to the
Indenture Trustee an Independent Certificate as to the same matters, if the fair value to the Issuer of the securities to be so
deposited and of all other such securities made the basis of any such withdrawal or release since the commencement of the then-current
fiscal year of the Issuer, as set forth in the certificates delivered pursuant to Section 10.01(b) and this Section 10.01(c),

with respect to any securities so deposited, if the fair value thereof to the Issuer as set forth in the related Officer’s
Certificate is less than the lesser of (A) $25,000 or (B) one percent of the Outstanding Amount of the Environmental Trust Bonds.


 






     67


     


    

 


(d)              
 Whenever any property or securities are to be released from the Lien of this Indenture other than pursuant to Section
8.02(e), the Issuer shall also furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion
of each person signing such certificate as to the fair value (within ninety (90) days of such release) of the property or securities
proposed to be released and stating that in the opinion of such person the proposed release will not impair the security under
this Indenture in contravention of the provisions hereof.


 


(e)              
Whenever the Issuer is required to furnish to the Indenture Trustee an Officer’s Certificate certifying or stating
the opinion of any signatory thereof as to the matters described in Section 10.01(d), the Issuer shall also furnish to the
Indenture Trustee an Independent Certificate as to the same matters if the fair value of the property or securities with respect
thereto, or securities released from the Lien of this Indenture (other than pursuant to Section 8.02(e)) since the commencement
of the then-current calendar year, as set forth in the certificates required by Section 10.01(d) and this Section 10.01(e),
equals 10 percent or more of the Outstanding Amount of the Environmental Trust Bonds, but such certificate need not be furnished
in the case of any release of property or securities if the fair value thereof as set forth in the related Officer’s Certificate
is less than the lesser of (A) $25,000 or (B) one percent of the then Outstanding Amount of the Environmental Trust Bonds.


 


(f)                Notwithstanding
any other provision of this Section 10.01, the Indenture Trustee may (A) collect, liquidate, sell or otherwise dispose
of the Environmental Control Property and the other Environmental Trust Bond Collateral as and to the extent permitted or required
by the Basic Documents and (B) make cash payments out of the Collection Account as and to the extent permitted or required by
the Basic Documents.


 


Section 10.02. 
Form of Documents Delivered to Indenture Trustee. In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by
the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may
certify or give an opinion as to such matters in one or several documents.


 


Any certificate or opinion of a Responsible
Officer of the Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his or her certificate or opinion is based are erroneous. Any Opinion of Counsel may be
based, insofar as it relates to factual matters (including financial and capital markets), upon a certificate or opinion of, or
representations by, an officer or officers of the Servicer or the Issuer and other documents necessary and advisable in the judgment
of counsel delivering such Opinion of Counsel.


 


Whenever in this Indenture, in
connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuer shall
deliver any document as a condition of the granting of such application, or as evidence of the Issuer’s compliance with
any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the
effective date of such certificate or report (as the case may be), of the facts and opinions stated in such document shall in
such case be conditions precedent to the right of the Issuer to have such application granted or to the sufficiency of such
certificate or report. The foregoing shall not, however, be construed to affect the Indenture Trustee’s right to rely
conclusively upon the truth and accuracy of any statement or opinion contained in any such document as provided in Article
VI.


 






     68


     


    

  



 


Where any Person is required to make, give
or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture,
they may, but need not, be consolidated and form one instrument.


 


Section 10.03. 
Acts of Holders.


 


(a)             Any
request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by agents duly appointed in writing, and except as herein otherwise expressly provided such action shall become effective
when such instrument or instruments are delivered to the Indenture Trustee and, where it is hereby expressly required, to the
Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to
as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument
or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01)
conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 10.03.


 


(b)             The
fact and date of the execution by any Person of any such instrument or writing may be proved in any manner that the Indenture
Trustee deems sufficient.

ownership of Environmental Trust Bonds shall be proved by the Environmental Trust Bond Register.


 


(d)             Any
request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Environmental Trust Bonds
shall bind the Holder of every Environmental Trust Bond issued upon the registration thereof or in exchange therefor or in lieu
thereof, in respect of anything done, omitted or suffered to be done by the Indenture Trustee or the Issuer in reliance thereon,
whether or not notation of such action is made upon such Environmental Trust Bond.


 


Section 10.04. 
Notices, etc., to Indenture Trustee, Issuer and Rating Agencies. Any notice, report or other communication given

Section 10.05. 
Notices to Holders; Waiver. Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class, postage prepaid to each
Holder affected by such event, at such Holder’s address as it appears on the Environmental Trust Bond Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice
to Holders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Holder
shall affect the sufficiency of such notice with respect to other Holders, and any notice that is mailed in the manner herein provided
shall conclusively be presumed to have been duly given.


 


Where this Indenture provides for notice in
any manner, such notice may be waived in writing by any Person entitled to receive such notice, either before or after the event,
and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Indenture Trustee,
but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such a waiver.


 


In case, by reason of the suspension of regular
mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event of
Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice
as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.


 






     70


     


    

 


Where this Indenture provides for notice to
the Rating Agencies, failure to give such notice shall not affect any other rights or obligations created hereunder and shall not
under any circumstance constitute a Default or Event of Default.


 


Section 10.06. 
Rule 17g-5 Compliance. The Indenture Trustee agrees that any notice, report, request for satisfaction of the Rating
Agency Condition, document or other information provided by the Indenture Trustee to any Rating Agency under this Indenture or
any other Basic Document to which it is a party for the purpose of determining or confirming the credit rating of the Environmental
Trust Bonds or undertaking credit rating surveillance of the Environmental Trust Bonds shall be provided, substantially concurrently,
to the Servicer for posting on a password-protected website (the “17g-5 Website”). The Servicer shall be responsible
for posting all of the information on the 17g-5 Website.


 


Section 10.07. 
Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision
hereof that is required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision
shall control.

Section 10.10. 
Severability. Any provision in this Indenture or in the Environmental Trust Bonds that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without
invalidating the remainder of such provision (if any) or the remaining provisions hereof (unless such construction shall be unreasonable),
and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in
any other jurisdiction.


 


Section 10.11. 
Benefits of Indenture. Nothing in this Indenture or in the Environmental Trust Bonds, express or implied, shall give
to any Person, other than the parties hereto and their successors hereunder, and the Holders, and any other party secured hereunder,
and any other Person with an ownership interest in any part of the Environmental Trust Bond Collateral, any benefit or any legal
or equitable right, remedy or claim under this Indenture.


 


Section 10.12.  Legal
Holidays. In any case where the date on which any payment is due shall not be a Business Day, then (notwithstanding any
other provision of the Environmental Trust Bonds or this Indenture) payment need not be made on such date, but may be made on
the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and no
interest shall accrue for the period from and after any such nominal date.

recording is to be effected by the Issuer and at its expense accompanied by an Opinion of Counsel at the Issuer’s cost and

of the Holders or any other Person secured hereunder or for the enforcement of any right or remedy granted to the Indenture Trustee
under this Indenture.

Recourse to Issuer. No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or

the Managers or any owner of a membership interest in the Issuer (including Wisconsin Electric) in its respective individual
capacity, or of any successor or assign of any of them in their respective individual or corporate capacities, except as any
such Person may have expressly agreed in writing. Each Holder by accepting an Environmental Trust Bond specifically confirms
the nonrecourse nature of these obligations, and waives and releases all such liability. The waiver and release are part of
the consideration for the issuance of the Environmental Trust Bonds. Notwithstanding any provision of this Indenture or the
Series Supplement to the contrary, Holders shall look only to the Environmental Trust Bond Collateral with respect to any
amounts due to the Holders hereunder and under the Series Supplement and the Environmental Trust Bonds and, in the event such
Environmental Trust Bond Collateral is insufficient to pay in full the amounts owed on the Environmental Trust Bonds, shall
have no recourse against the Issuer in respect of such insufficiency. Each Holder by accepting an Environmental Trust Bond
specifically confirms the nonrecourse nature of these obligations and waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Environmental Trust Bonds.

This Tranche { } Environmental Trust Bond,

including this Tranche { } Environmental Trust Bond, Series 2021 (herein called the “Tranche { } Environmental Trust Bonds”),
all issued and to be issued under that certain Indenture dated as of [•], 2021 (as supplemented by the Series Supplement
(as defined below), the “Indenture”), between the Issuer and U.S. Bank, National Association, in its capacity
as indenture trustee (the “Indenture Trustee”, which term includes any successor indenture trustee under the
Indenture) and in its separate capacity as a securities intermediary (the “Securities Intermediary”, which term
includes any successor securities intermediary under the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee
and the Holders of the Environmental Trust Bonds. For purposes herein, “Series Supplement” means that certain
Series Supplement dated as of [______], 2021 between the Issuer and the Indenture Trustee. All terms used in this Environmental
Trust Bond that are defined in the Indenture, as amended, restated, supplemented or otherwise modified from time to time, shall
have the meanings assigned to such terms in the Indenture.


 


All [Tranches]3
of the Environmental Trust Bonds are and will be equally and ratably secured by the Environmental Trust Bond Collateral
pledged as security therefor as provided in the Indenture.


 


The principal of this Tranche { }
Environmental Trust Bond shall be payable on each Payment Date only to the extent that amounts in the Collection Account are
available therefor, and only until the outstanding principal balance thereof on the preceding Payment Date (after giving
effect to all payments of principal, if any, made on the preceding Payment Date) has been reduced to the principal balance
specified in the Expected Amortization Schedule which is attached to the Series Supplement as Schedule A, unless
payable earlier because an Event of Default shall have occurred and be continuing and the Indenture Trustee or the Holders
representing not less than a majority of the Outstanding Amount of the Environmental Trust Bonds have declared the
Environmental Trust Bonds to be immediately due and payable in accordance with Section 5.02 of the Indenture (unless
such declaration shall have been rescinded and annulled in accordance with Section 5.02 of the Indenture). However,
actual principal payments may be made in lesser than expected amounts and at later than expected times as determined pursuant
to Section 8.02 of the Indenture. The entire unpaid principal amount of this Tranche { } Environmental Trust Bond
shall be due and payable on the Final Maturity Date hereof. Notwithstanding the foregoing, the entire unpaid principal amount
of the Environmental Trust Bonds shall be due and payable, if not then previously paid, on the date on which an Event of
Default shall have occurred and be continuing and the Indenture Trustee or the Holders of the Environmental Trust Bonds
representing not less than a majority of the Outstanding Amount of the Environmental Trust Bonds have declared the
Environmental Trust Bonds to be immediately due and payable in the manner provided in Section 5.02 of the Indenture
(unless such declaration shall have been rescinded and annulled in accordance with Section 5.02 of the Indenture). All
principal payments on the Tranche { } Environmental Trust Bonds shall be made pro rata to the Holders of the Tranche { }
Environmental Trust Bonds entitled thereto based on the respective principal amounts of the Tranche { } Environmental Trust
Bonds held by them.

the designated transferee or transferees. No service charge will be charged for any registration of transfer or exchange of this
Tranche { } Environmental Trust Bond, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section
2.04 or Section 2.06 of the Indenture not involving any transfer.


 


Each Holder, by acceptance of a Tranche
{ } Environmental Trust Bond, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer or the Indenture Trustee on the Tranche { } Environmental Trust Bonds or under the Indenture or any
certificate or other writing delivered in connection therewith, against (a) any owner of a membership interest in the Issuer
(including Wisconsin Electric Power Company) or (b) any shareholder, partner, owner, beneficiary, agent, officer, director or

their individual or corporate capacities, except as any such Person may have expressly agreed in writing. Each Holder by

and releases all such liability. The waiver and release are part of the consideration for issuance of the Tranche { }
Environmental Trust Bonds.

Amount of the Environmental Trust Bonds, on behalf of the Holders of all the Environmental Trust Bonds, to waive compliance by
the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Tranche { } Environmental Trust Bond (or any one of more Predecessor Environmental Trust
Bonds) shall be conclusive and binding upon such Holder and upon all future Holders of this Tranche { } Environmental Trust Bond
and of any Tranche { } Environmental Trust Bond issued upon the registration of transfer hereof or in exchange hereof or in lieu
hereof whether or not notation of such consent or waiver is made upon this Tranche { } Environmental Trust Bond. The Indenture

SECTION 2.Deposit Accounts.


 


(a)       The
parties hereto each acknowledge that collections with respect to the Initial Customer Property, the Additional Customer Property
and the Receivables may from time to time be deposited into one or more designated accounts of the Company or the Buyer (the “Deposit
Accounts”) and that such Deposit Accounts may be subject to a security interest of the Administrative Agent and account

remit funds to the Receivables Purchasers and the Buyer at the times and in the manner specified in the Receivables Agreements;
provided, that:


 


(A)       to the extent the combined
amounts of remittance are insufficient to satisfy amounts owed in respect of the Initial Customer Charges, the Additional Customer
Charges and the Receivables, such allocation and remittances shall be made [on a pro rata basis as among the Initial Customer Charges,

(B)       late

the Initial Bond Trustee, if such late payment penalties are allocable to the Initial Customer Charges and are not allowed to be
retained by the Company under the Initial Bond Agreements, (x) to the Additional Bond Trustee, if such late payment penalties are
allocable to the Additional Customer Charges and are not allowed to be retained by the Company under the Additional Bond Agreements,
(y) to the Receivables Purchasers to the extent that any such late payment penalties are included in the Receivables sold
to the Receivables Purchasers, and (z) otherwise to the Company; and

Initial Bond Issuer, the Additional Bond Trustee, the Additional Bond Issuer, the Buyer and the Receivables Purchasers shall each
have the right to require an accounting from time to time of collections, deposits, allocations and remittances by the Company
relating to the Deposit Accounts.  Because of difficulties inherent in allocating collections on a daily basis, (i) the Initial
Property Servicer may implement  estimates for the purposes of determining the amount of collections which are allocable to
the Initial Customer Property, which allocations will be subject to annual reconciliations in accordance with the terms of the
Initial Bond Agreements but will otherwise be deemed conclusive, subject to reconciliation as provided in the following sentences
and (ii) the Additional Property Servicer may implement  estimates for the purposes of determining the amount of collections
which are allocable to the Additional Customer Property, which allocations will be subject to annual reconciliations in accordance
with the terms of the Additional Bond Agreements but will otherwise be deemed conclusive, subject to reconciliation as provided
in the following sentences; provided that unless an Event of Default (as defined in the Initial Indenture or the Additional
Indenture and any corresponding term in the Receivables Purchase Agreement) has occurred and is continuing, the Company shall only
be required to prepare one such accounting during any fiscal year. 


 


In the event that the estimated
remittances to the Initial Bond Issuer for any calendar year are less than the actual amounts of Initial Customer Charge
collections, the Initial Bond Issuer shall look to the Initial Property Servicer for any such shortfall and shall have no
claims against the Receivables Purchasers or the Additional Bond Issuer for such amounts.   In the event that the
estimated remittances to the Initial Bond Issuer are greater than the actual amounts of Initial Customer Charge collections,
the Initial Property Servicer shall have the right, in accordance with the terms of the Initial Bond Agreements, to net an
amount equal to such excess collections out of monies otherwise to be paid to the Initial Bond Issuer, and the Receivables
Purchasers acknowledge that they shall look solely to the Initial Property Servicer for such excess collections and shall
have no claims against the Initial Bond Issuer for such funds.  In the event that the estimated remittances to the
Additional Bond Issuer for any calendar year are less than the actual amounts of Additional Customer Charge collections, the
Additional Bond Issuer shall look to the Additional Property Servicer for any such shortfall and shall have no claims against
the Initial Bond Issuer or the Receivables Purchasers for such amounts. In the event that the estimated remittances to the
Additional Bond Issuer are greater than the actual amounts of Additional Customer Charge collections, the Additional Property
Servicer shall have the right, in accordance with the terms of the Additional Bond Agreements, to net an amount equal to such
excess collections out of monies otherwise to be paid to the Additional Bond Issuer, and the Receivables Purchasers
acknowledge that they shall look solely to the Additional Property Servicer for such excess collections and shall have no
claims against the Additional Bond Issuer for such funds.  Notwithstanding the foregoing, nothing in this paragraph
shall prohibit any party from netting any such reconciliation payments owing by such party (the “remitting
party”) to another party (the “receiving party”) against the amounts to be paid hereunder to the remitting
party by such receiving party.


 






    D-7 


     


    

 


(c) The Initial Bond Trustee, the
Initial Bond Issuer, the Additional Bond Trustee and the Additional Bond Issuer waive any interest in deposits to the Deposit Accounts
to the extent that they are properly allocable to Collections with respect to Receivables. The Administrative Agent and Buyer and
the Additional Bond Trustee and the Additional Bond Issuer waive any interest in deposits to the Deposit Accounts to the extent
that they are properly allocable to Initial Customer Charges. The Administrative Agent and Buyer and the Initial Bond Trustee and
the Initial Bond Issuer waive any interest in deposits to the Deposit Accounts to the extent they are properly allocable to the
Additional Customer Charges. Each of the parties hereto acknowledges the respective ownership and security interests of the others
in amounts on deposit in the Deposit Accounts to the extent of their respective interests as described in this Agreement.


 


(d) In no event may the Initial
Bond Trustee take any action with respect to the Initial Customer Charges in a manner that would result in the Initial Bond Trustee
obtaining possession of, or any control over, collections of Additional Customer Charges, Collections of Receivables or any Deposit
Account.  In the event that the Initial Bond Trustee obtains possession of any Collections related to the Receivables, the
Initial Bond Trustee shall notify the Administrative Agent of such fact, shall hold such Collections in trust and shall promptly
deliver them to the Administrative Agent upon request.  In the event that the Initial Bond Trustee obtains possession of any
collections of Additional Customer Charges, the Initial Bond Trustee shall notify the Additional Bond Trustee of such fact, shall
hold such collections in trust and shall promptly deliver them to the Additional Bond Trustee upon request. 


 


In no event may the Additional Bond
Trustee take any action with respect to the Additional Customer Charges in a manner that would result in the Additional Bond
Trustee obtaining possession of, or any control over, collections of Initial Customer Charges, Collections of Receivables or
any Deposit Account.  In the event that the Additional Bond Trustee obtains possession of any Collections related to the
Receivables, the Additional Bond Trustee shall notify the Administrative Agent of such fact, shall hold such Collections in
trust and shall promptly deliver them to the Administrative Agent upon request.  In the event that the Additional Bond
Trustee obtains possession of any collections of Initial Customer Charges, the Additional Bond Trustee shall notify the
Initial Bond Trustee of such fact, shall hold such collections in trust and shall promptly deliver them to the Initial Bond
Trustee upon request.

Except as contemplated by this Section 2
with respect to the Administrative Agent’s exercise of control over the Deposit Accounts, in no event may the Administrative
Agent or Buyer take any action with respect to the collection of Receivables in a manner that would result in the Administrative
Agent or Buyer, as applicable, obtaining possession of, or any control over, collections of Initial Customer Charges or collections
of Additional Customer Charges. In the event that the Administrative Agent or Buyer obtains possession of any collections of Initial
Customer Charges, the Administrative Agent or Buyer, as applicable, shall notify the Initial Bond Trustee of such fact, shall hold
such collections in trust and shall promptly deliver them to the Initial Bond Trustee upon request. In the event that the Administrative
Agent or Buyer obtains possession of any collections of Additional Customer Charges, the Administrative Agent or Buyer, as applicable,
shall notify the Additional Bond Trustee of such fact, shall hold such collections in trust and shall promptly deliver them to
the Additional Bond Trustee upon request.

successor shall be subject to satisfaction of the Initial Bonds Rating Agency Condition (as defined below) and the Additional
Bonds Rating Agency Condition (as defined below) and otherwise satisfy the provisions of the Initial Servicing Agreement, the

automatically cause the removal of the Company as the Initial Property Servicer or as the Receivables Servicer,
