ARTICLE
I.

DEFINITIONS AND RULES OF CONSTRUCTION

 

SECTION 1.01.                   
Definitions and Rules of Construction.

 

(a)       Unless
otherwise defined herein, capitalized terms used herein shall have the meanings assigned to them in that certain Indenture
(including Appendix A thereto) dated as of the date hereof (the “Indenture”), between the Issuer and U.S.
Bank National Association, in its capacity as indenture trustee (the “Indenture Trustee”) and in its separate

ARTICLE
II.

TRANSFER OF ENVIRONMENTAL CONTROL PROPERTY

 

SECTION 2.01.                   
Transfer of Environmental Control Property.

 

(a)               In
consideration of the Issuer’s delivery to or upon the order of the Seller of $113,507,309, subject to the conditions
specified in Section 2.02, the Seller does hereby irrevocably sell, assign and otherwise transfer to the Issuer, without
recourse or warranty, except as set forth herein, all right, title and interest of the Seller in, to and under the Environmental
Control Property (such sale, assignment and transfer of the Environmental Control Property includes, to the fullest extent permitted
by the Statute, the right to impose, collect and receive Environmental Control Charges and the assignment of all revenues and
proceeds of or arising from the Environmental Control Charges related to the Environmental Control Property, as the same may be
adjusted from time to time). Such sale, assignment and transfer of the Environmental Control Property is hereby expressly stated to
be a sale or other absolute transfer and, pursuant to Section 196.027(5)(c) of the Statute and the Financing Order, shall constitute
a sale and absolute transfer of all of the Seller’s right, title and interest, in, to and under, and not a pledge of, or
secured transaction relating to, the Seller’s right, title and interest, in, to and under the Environmental Control Property.
The preceding sentence is the statement referred to in Section 196.027(5)(c) of the Statute. The Seller and the Issuer agree that
after giving effect to the sale, assignment and transfer contemplated hereby the Seller has no right, title or interest in, to or
under the Environmental Control Property to which a security interest could attach because (i) it has sold, assigned and transferred
all right, title and interest in and to the Environmental Control Property to the Issuer, and (ii) as provided in Section
196.027(5)(c) of the Statute, after such transfer the Environmental Control Property is not subject to any claims of the Seller or
the Seller’s creditors, other than creditors holding a prior security interest in the Environmental Control Property perfected
under Section 196.027(5)(b) of the Statute. If such sale, assignment and transfer is held by any court of competent jurisdiction not
to be an absolute transfer as provided in Section 196.027(5)(c) of the Statute, then such sale, assignment and transfer shall be
treated as a pledge of the Environmental Control Property and as the creation of a security interest (within the meaning of the
Statute and the applicable UCC) in the Environmental Control Property and, without prejudice to its position that it has absolutely
transferred all of its rights in the Environmental Control Property to the Issuer, the Seller hereby grants a security interest in
the Environmental Control Property to the Issuer (and to the Indenture Trustee for the benefit of the Secured Parties) to secure
their respective rights under the Basic Documents to receive the Environmental Control Charges and all other Environmental Control
Property (the “Back-Up Security Interest”).(b)Subject to Section 2.02, the Issuer does hereby purchase the
Environmental Control Property from the Seller for the consideration set forth in this Section 2.01(a).

the Environmental Control Property to be transferred on the Closing Date;

 

(b)             
on or prior to the Closing Date, the Seller shall have received the Financing Order creating the Environmental Control Property;

and correct with the same force and effect as if made on the Closing Date (except to the extent that they relate to an earlier
date); on and as of the Closing Date no breach of any covenant or agreement of the Seller contained in this Sale Agreement has
occurred and is continuing; and no Servicer Default shall have occurred and be continuing;

 

(e)               as of the Closing Date, (i) the Issuer shall have sufficient funds available to pay the purchase price for the Environmental
Control Property to be transferred on such date and (ii) all conditions to the issuance of the Environmental Trust Bonds intended
to provide such funds set forth in the Indenture shall have been satisfied or waived;

 

(f)               on or prior to the Closing Date, the Seller shall have taken all action required to transfer to the Issuer ownership of
the Environmental Control Property to be transferred on such date, free and clear of all Liens other than Liens created by the
Issuer pursuant to the Basic Documents and to perfect such transfer, including, without limitation, filing any statements or filings
under the Statute or the applicable UCC;

 

(g)               the Seller shall have delivered to the Rating Agencies and the Issuer any Opinions of Counsel required by the Rating Agencies;

counsel (as selected by the Seller, and in form and substance reasonably satisfactory to the Issuer and the Underwriters) to the
effect that (i) the Issuer will not be subject to U.S. federal income tax as an entity separate from its sole owner and that the
Environmental Trust Bonds will be treated as debt of the Issuer’s sole owner for U.S. federal income tax purposes and (ii)
for U.S. federal income tax purposes, the Seller will not be treated as recognizing gross income upon the issuance of the Environmental
Trust Bonds; 

 

(i)                on and as of the Closing Date, each of the LLC Agreement, the Servicing Agreement, this Sale Agreement, the Indenture, the
Financing Order and the Statute shall be in full force and effect;

 

(j)               
 the Environmental Trust Bonds shall have received a rating or ratings required by the Financing Order;

 

    3 

     

    

 

(k)              
the Seller shall have delivered to the Indenture Trustee and the Issuer an Officer’s Certificate confirming the satisfaction
of each condition precedent specified in this Section 2.02; and

 

(l)               
the Seller shall have received the purchase price for the Environmental Control Property.

makes the following representations and warranties, as of the Closing Date, and the Seller acknowledges that the Issuer has relied
thereon in acquiring the Environmental Control Property. The representations and warranties shall survive the sale, assignment
and transfer of the Environmental Control Property to the Issuer and the pledge thereof to the Indenture Trustee pursuant to the
Indenture. The Seller agrees that (i) the Issuer may assign the right to enforce the following representations and warranties to
the Indenture Trustee and (ii) the representations and warranties inure to the benefit of the Issuer and the Indenture Trustee.

 

SECTION 3.01.         Organization and Good Standing. The Seller is a corporation duly organized, validly existing and in active status

are currently owned and to conduct its business as such business is now conducted by it, and has the requisite corporate power
and authority to obtain the Financing Order and own the rights and interests under the Financing Order and to sell and assign those
rights and interests to the Issuer whereupon such rights and interests shall become “environmental control property”
as defined in Section 196.027(1)(h) of the Statute.

 

SECTION 3.02.         Due Qualification. The Seller is duly qualified to do business and is in good standing, and has obtained all necessary
licenses and approvals, in all jurisdictions in which the ownership or lease of property or the conduct of its business shall require
such qualifications, licenses or approvals (except where the failure to so qualify or obtain such licenses and approvals would
not be reasonably likely to have a material adverse effect on the Seller’s business, operations, assets, revenues or properties).

 

SECTION 3.03.         Power and Authority. The Seller has the requisite corporate power and authority to execute and deliver this Sale
Agreement and to carry out its terms; and the execution, delivery and performance of obligations under this Sale Agreement have
been duly authorized by all necessary corporate action on the part of the Seller under its organizational or governing documents
and laws.

 

SECTION
3.04.          Binding
Obligation. This Sale Agreement constitutes a legal, valid and binding obligation of the Seller, enforceable against the
Seller in accordance with its terms, subject to applicable insolvency, reorganization, moratorium, fraudulent transfer and
other laws relating to or affecting creditors’ or secured parties’ rights generally from time to time in effect
and to general principles of equity (including concepts of materiality, reasonableness, good faith and fair dealing),

SECTION 3.05.         
No Violation. The consummation of the transactions contemplated by this Sale Agreement and the fulfillment of the
terms hereof do not and will not: (a) conflict with or result in any breach of any of the terms and provisions of, or constitute
(with or without notice or lapse of time) a default under, the Seller’s organizational documents or any indenture, or other
material agreement or instrument to which the Seller is a party or by which it or any of its property is bound; or (b) result in
the creation or imposition of any Lien upon any of the Seller’s properties pursuant to the terms of any such indenture, agreement
or other instrument (other than any Lien that may be granted in the Issuer’s favor or any Lien under the Basic Documents
or any Liens created by the Issuer pursuant to the Statute) or violate any existing law or any existing order, rule or regulation
applicable to the Seller of any Governmental Authority having jurisdiction over the Seller or its properties.

 

SECTION 3.06.         
No Proceedings.  There are no proceedings pending and, to the Seller’s
knowledge, there are no proceedings threatened and, to the Seller’s knowledge, there are no investigations pending or threatened,
before any Governmental Authority having jurisdiction over the Seller or its properties involving or relating to the Seller or
the Issuer or, to the Seller’s knowledge, any other Person: (a) asserting the invalidity of the Statute, the Financing Order,
this Sale Agreement, any of the other Basic Documents or the Environmental Trust Bonds; (b) seeking to prevent the issuance of
the Environmental Trust Bonds or the consummation of any of the transactions contemplated by this Sale Agreement or any of the

federal income tax or state income or franchise tax classification of the Environmental Trust Bonds as debt.

 

SECTION 3.07.         
Approvals. Except for UCC financing statement filings and other filings under the Statute, no approval, authorization,
consent, order or other action of, or filing with, any Governmental Authority is required in connection with the execution and
delivery by the Seller of this Sale Agreement, the performance by the Seller of the transactions contemplated hereby or the fulfillment
by the Seller of the terms hereof, except those that have been obtained or made and those that the Seller, in its capacity as Servicer
under the Servicing Agreement, is required to make in the future pursuant to the Servicing Agreement.

 

SECTION 3.08.         
The Environmental Control Property.

 

(a)        
Information. Subject to Section 3.08(h) below, at the Closing Date, all written information, as amended or
supplemented from time to time, provided by the Seller to the Issuer with respect to the Environmental Control Property (including
the Expected Amortization Schedule and the Financing Order) is true and correct in all material respects.

 

    5

     

    

 

(b)         Title.
It is the intention of the parties hereto that the sale, assignment and transfer of the Environmental Control Property herein
contemplated constitutes a sale or other absolute transfer of the Environmental Control Property from the Seller to the
Issuer and that no interest in, or right or title to, the Environmental Control Property shall be part of the Seller’s
estate in the event of the filing of a bankruptcy petition by or against the Seller under any bankruptcy law. No portion of
the Environmental Control Property has been sold, transferred, assigned, pledged or otherwise conveyed by the Seller to any
Person other than the Issuer, and, to the Seller’s knowledge (after due inquiry), no security agreement, financing
statement or equivalent security or lien instrument listing the Seller as debtor covering all or any part of the
Environmental Control Property is on file or of record in any jurisdiction, except such as may have been filed, recorded or
made in favor of the Issuer or the Indenture Trustee in connection with the Basic Documents. The Seller has not authorized
the filing of any financing statement against it that includes a description of Environmental Trust Bond Collateral including
the Environmental Control Property other than any financing statement filed, recorded or made in favor of the Issuer or the
Indenture Trustee in connection with the Basic Documents.

 

(c)        
Transfer Filings. On the Closing Date, immediately upon the sale hereunder, the Environmental Control Property shall
be validly transferred and sold to the Issuer, and the Issuer shall own all of the Environmental Control Property free and clear
of all Liens other than Liens created by the Issuer pursuant to the Indenture. All actions or filings, including filings under
the Statute and the applicable UCC, necessary to give the Issuer a valid ownership interest in the Environmental Control Property
have been taken or made. No further action is required to establish the Issuer’s ownership interest. All applicable filings
also have been made to the extent required by applicable law in any jurisdiction to perfect the Back-Up Security Interest granted
by the Seller to the Issuer.

 

(d)        
Financing Order; Other Approvals. On the Closing Date, under the laws of the State of Wisconsin and the United States
in effect on the Closing Date: (i) the Financing Order pursuant to which the rights and interests of the Seller, including the
right to impose, collect and receive the Environmental Control Charges and, in and to the Environmental Control Property transferred
on such date have been created, is Final and in full force and effect; (ii) as of the issuance of the Environmental Trust Bonds,
the Environmental Trust Bonds are entitled to the protections provided by the Statute and, accordingly, the Financing Order and
the Environmental Control Charges are not revocable by the PSCW; (iii) under the terms of the Financing Order, the initial Environmental
Control Charges shall become effective the first day of the first full month following the issuance of the Environmental Trust
Bonds; (iv) the process by which the Financing Order creating the Environmental Control Property was adopted and approved, and
the Financing Order and the Tariff themselves, comply with all applicable laws, rules and regulations; and (v) no other approval,
authorization, consent, order or other action of, or filing with any Governmental Authority is required in connection with the
creation of the Environmental Control Property transferred on such date, except those that have been obtained or made.

 

    6

     

    

 

(e)         State
Action. Under the Statute, the State of Wisconsin pledged to and agreed with the Holders not to take or permit any action
that impairs the value of the Environmental Control Property or, except for the True-Up Adjustments, reduce, alter or impair
the Environmental Control Charges that are imposed, collected and remitted for the benefit of the Holders until any
principal, interest, premium, or other charge incurred, or contract to be performed, in connection with the Environmental
Trust Bonds are paid or performed in full. Furthermore, under the contract clauses of the State of Wisconsin and United
States constitutions, the State of Wisconsin, could not take any action of a legislative character, including the repeal or
amendment of the Statute or the Financing Order that substantially impairs the value of the Environmental Control Property
or, except for the True-Up Adjustments, substantially reduces, alters or impairs the Environmental Control Charges to be
imposed, collected and remitted to the Issuer for the benefit of the Holders of the Environmental Trust Bonds, unless such
action is a reasonable exercise of the sovereign powers of the State of Wisconsin and of a character reasonable and
appropriate to further a significant and legitimate public purpose and, under the takings clauses of the State of Wisconsin
and United States Constitution, the State of Wisconsin could not repeal or amend the Statute or the Financing Order or take
any other action in contravention of the State Pledge, without paying just compensation to the Holders, as determined by a
court of competent jurisdiction, if doing so would constitute a permanent appropriation of a substantial property interest of
the Holders in the Environmental Control Property and deprives the Holders of their reasonable expectations arising from
their investments in the Environmental Trust Bonds. There is no assurance, however, that, even if a court were to award just
compensation, it would be sufficient to pay the full amount of principal of and interest on the Environmental Trust
Bonds.

 

(f)        
Assumptions. On the Closing Date, based upon the information available to the Seller on such date, the assumptions
used in calculating the Environmental Control Charges are reasonable and are made in good faith. Notwithstanding the foregoing,
the Seller makes no representation or warranty, express or implied, that amounts actually collected arising from those Environmental
Control Charges will in fact be sufficient to meet the payment obligations on the Environmental Trust Bonds or that the assumptions
used in calculating such Environmental Control Charges will in fact be realized.

 

(g)       
Creation of Environmental Control Property. Upon the effectiveness of the Financing Order and the transfer of the
Environmental Control Property pursuant to this Sale Agreement:

 

(i)        
For purposes of the Statute, the Environmental Control Property constitutes a present property right;

 

(ii)       
the Environmental Control Property consists of the right to impose, collect and receive Environmental Control Charges in
an amount necessary to provide for recovery of the principal of and interest on the Environmental Trust Bonds and other Financing
Costs, the right to obtain True-Up Adjustments of the Environmental Control Charges as provided in the Financing Order and the
Statute, and all revenues or other proceeds arising from those rights and interests; and

 

(iii)      the
Environmental Control Property shall continue to exist until the Environmental Trust Bonds are paid in full and all Financing Costs
have been recovered in full.

 

(h)         Nature
of Representations and Warranties. The representations and warranties set forth in this Section 3.08, insofar as
they involve conclusions of law, are made not on the basis that the Seller purports to be a legal expert or to be rendering
legal advice, but rather to reflect the parties’ good faith understanding of the legal basis on which the parties are
entering into this Sale Agreement and the other Basic Documents and the basis on which the Holders are purchasing the
Environmental Trust Bonds, and to reflect the parties’ agreement that, if such understanding turns out to be incorrect
or inaccurate, the Seller will be obligated to indemnify the Issuer and its permitted assigns (to the extent required by and
in accordance with Section 5.01), and that the Issuer and its permitted assigns will be entitled to enforce any rights
and remedies under the Basic Documents on account of such inaccuracy to the same extent as if the Seller had breached any
other representations or warranties hereunder.

 

    7

     

    

 

(i)         
Prospectus. As of the date hereof, the information describing the Seller under the caption “Review of the Environmental
Control Property” and “Wisconsin Electric Power Company — The Depositor, Sponsor, Seller and Initial Servicer”
in the prospectus dated May 4, 2021 relating to the Environmental Trust Bonds is true and correct in all material respects.

 

(j)         
Solvency. After giving effect to the sale of the Environmental Control Property hereunder, the Seller:

 

(i)        
is solvent and expects to remain solvent;

 

(ii)       
is adequately capitalized to conduct its business and affairs considering its size and the nature of its business and intended
purpose;

 

(iii)      
is not engaged in nor does it expect to engage in a business for which its remaining property represents unreasonably small
capital;

 

(iv)      
reasonably believes that it will be able to pay its debts as they come due; and

 

(v)       
is able to pay its debts as they mature and does not intend to incur, or believes that it will not incur, indebtedness that
it will not be able to repay at its maturity.

 

(k)        
No Court Order. There is no order by any court providing for the revocation, alteration, limitation or other impairment
of the Statute, the Financing Order, the Environmental Control Property or the Environmental Control Charges or any rights arising
under any of them or that seeks to enjoin the performance of any obligations under the Financing Order.

 

(l)         Survival of Representations and Warranties The representations and warranties set forth in this Section 3.08
shall survive the execution and delivery of this Sale Agreement and may not be waived by any party hereto except pursuant to a
written agreement executed in accordance with Article VI and as to which the Rating Agency Condition has been satisfied.

 

SECTION 3.09.          Limitations
on Representations and Warranties. Without prejudice to any of the other rights of the parties, the Seller will not be in
breach of any representation or warranty as a result of a change in law by means of any legislative enactment, constitutional
amendment or voter referendum. THE SELLER MAKES NO REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, THAT BILLED ENVIRONMENTAL
CONTROL CHARGES WILL BE ACTUALLY COLLECTED FROM CUSTOMERS AND NO REPRESENTATION THAT AMOUNTS COLLECTED WILL BE SUFFICIENT TO
MEET THE OBLIGATIONS ON THE ENVIRONMENTAL TRUST BONDS.

and, to the extent consistent with applicable state, local and other tax law, for purposes of state, local or other taxes, so long
as any of the Environmental Trust Bonds are Outstanding, the Seller agrees to treat such Environmental Trust Bonds as indebtedness

Sale Agreement, (i) to the fullest extent permitted by law, including applicable PSCW Regulations and the Statute, the Issuer shall
have all of the rights originally held by the Seller with respect to the Environmental Control Property, including the right (subject
to the terms of the Servicing Agreement) to exercise any and all rights and remedies to collect any amounts payable by any Customer

of Title. The Seller shall execute and file such filings, including, without limitation, filings with the Wisconsin
Department of Financial Institutions pursuant to the Statute, and cause to be executed and filed such filings, all in such
manner and in such places as may be required by law to fully preserve, maintain, protect and perfect the ownership interest
of the Issuer, and the back-up precautionary security interest of the Issuer pursuant to Section 2.01, and the first
priority security interest of the Indenture Trustee in the Environmental Control Property, including, without limitation, all
filings required under the Statute and the applicable UCC relating to the transfer of the ownership of the rights and
interest in the Environmental Control Property by the Seller to the Issuer or the pledge of the Issuer’s interest in
the Environmental Control Property to the Indenture Trustee. The Seller shall deliver or cause to be delivered to the Issuer
and the Indenture Trustee file-stamped copies of, or filing receipts for, any document filed as provided above, as soon as
available following such filing. The Seller shall institute any action or proceeding necessary to compel performance by the
PSCW, the State of Wisconsin or any of their respective agents of any of their obligations or duties under the Statute or the
Financing Order and the Seller agrees to take such legal or administrative actions, including defending against or
instituting and pursuing legal actions and appearing or testifying at hearings or similar proceedings, in each case as may be
reasonably necessary (a) to seek to protect the Issuer and the Secured Parties from claims, state actions or other actions or
proceedings of third parties which, if successfully pursued, would result in a breach of any representation set forth in Article
III or any covenant set forth in Article IV and (b) to seek to block or overturn any attempts to cause a repeal
of, modification of or supplement to the Statute or the Financing Order, or the rights of Holders of the Environmental Trust
Bonds by legislative enactment or constitutional amendment that would be materially adverse to the Issuer or the Secured
Parties or which would otherwise cause an impairment of the rights of the Issuer or the Secured Parties. The costs of any
such actions or proceedings undertaken by the Seller will be reimbursed by the Issuer as an Operating Expense in accordance
with the priorities set forth in Section 8.02(e) of the Indenture. The Seller’s obligations pursuant to this Section
4.07 shall survive and continue notwithstanding the fact that the payment of Operating Expenses pursuant to Section
8.02(e) of the Indenture may be delayed (it being understood that the Seller may be required to advance its own funds to
satisfy its obligations hereunder).

 

    11

shall not, prior to the date which is one year and one day after the termination of the Indenture and payment in full of the Environmental
Trust Bonds or any other amounts owed under the Indenture, petition or otherwise invoke or cause the Issuer to invoke the process
of any Governmental Authority for the purpose of commencing or sustaining an involuntary case against the Issuer under any U.S.
federal or state bankruptcy, insolvency or similar law, appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator
or other similar official of the Issuer or any substantial part of the property of the Issuer, or ordering the winding up or liquidation
of the affairs of the Issuer.

its subsidiaries to, pay all material taxes, assessments and governmental charges imposed upon it or any of its properties or assets
or with respect to any of its franchises, business, income or property before any penalty accrues thereon if the failure to pay
any such taxes, assessments and governmental charges would, after any applicable grace periods, notices or other similar requirements,
result in a Lien on the Environmental Control Property; provided, that no such tax need be paid if the Seller or one of
its Affiliates is contesting the same in good faith by appropriate proceedings promptly instituted and diligently conducted and
if the Seller or such Affiliate has established appropriate reserves as shall be required in conformity with generally accepted
accounting principles.

 

SECTION 4.10.         
Notice of Breach to Rating Agencies, Etc. Promptly after obtaining knowledge thereof, in the event of a breach in
any material respect (without regard to any materiality qualifier contained in such representation, warranty or covenant) of any
of the Seller’s representations, warranties or covenants contained herein, the Seller shall promptly notify the Issuer, the
Indenture Trustee and the Rating Agencies of such breach. For the avoidance of doubt, any breach which would adversely affect scheduled
payments on the Environmental Trust Bonds will be deemed to be a material breach for purposes of this Section 4.10.

 

SECTION 4.11.         
Use of Proceeds. The Seller shall use the proceeds of the sale of the Environmental Control Property in accordance
with the Financing Order and the Statute.

negligence of such Indemnified Person or resulting from a breach of a representation or warranty made by such Indemnified Person
in any of the Basic Documents that gives rise to the Seller’s breach. The Seller shall
not be required to indemnify an 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 Seller, 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 Seller under this Section 5.01(f),
notify the Seller in writing of the commencement thereof. Failure by an Indemnified Person to so notify the Seller shall relieve
the Seller from the obligation to indemnify and hold harmless such Indemnified Person under this Section 5.01(f) only to
the extent that the Seller suffers actual prejudice as a result of such failure. With respect to any action, proceeding or investigation
brought by a third party for which indemnification may be sought under this Section 5.01(f), the Seller 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 Seller shall not thereafter be responsible for the
fees and expenses of any separate counsel retained by the Indemnified Person except as set forth below); provided, that
the 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 Seller’s election to assume the defense
of any action, proceeding or investigation, the Indemnified Person shall have the right to employ separate counsel (including local
counsel), and the Seller 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 Seller 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 Seller, (ii) the Seller
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, (iii) the Seller shall authorize the Indemnified Person to employ
separate counsel at the expense of the Seller or (iv) in the case of the Indenture Trustee, such action exposes the Indenture Trustee
to a material risk of criminal liability or forfeiture or a Servicer Default has occurred and is continuing. Notwithstanding the
foregoing, the Seller shall not be obligated to pay for the fees, costs and expenses of more than one separate counsel for the
Indemnified Persons other than one local counsel, if appropriate.

 

(g)         The
Seller shall indemnify the Servicer (if the Servicer is not the Seller) for the costs of any action instituted by the
Servicer pursuant to Section 5.02(d) of the Servicing Agreement which are not paid as Operating Expenses in accordance with
the priorities set forth in Section 8.02(e) of the Indenture.

 

    14

     

    

 

(h)       
The remedies provided in this Sale Agreement are the sole and exclusive remedies against the Seller for breach of its representations
and warranties in this Sale Agreement.

 

(i)         
Indemnification under this Section 5.01 shall survive any repeal of, modification of, or supplement to, or judicial
invalidation of, the Statute or the Financing Order and shall survive the resignation or removal of the Indenture Trustee or the
termination of this Sale Agreement and will rank pari passu with other general, unsecured obligations of the Seller. The Seller
shall not indemnify any party under this Section 5.01 for any changes in law after the Closing Date, whether such changes
in law are effected by means of any legislative enactment, any constitutional amendment or any final and non-appealable judicial
decision.

 

SECTION 5.02.          Merger,
Conversion or Consolidation of, or Assumption of the Obligations of, Seller. Any Person (a) into which the Seller may be
merged, converted or consolidated and which is a Permitted Successor, (b) that may result from any merger, conversion or
consolidation to which the Seller shall be a party and which is a Permitted Successor, (c) that may succeed to the properties
and assets of the Seller substantially as a whole and which is a Permitted Successor, (d) which results from the division of
the Seller into two or more Persons and which is a Permitted Successor, or (e) which otherwise succeeds to all or
substantially all of the retail electric distribution business of the Seller (a “Permitted Successor”) and
which Person in any of the foregoing cases executes an agreement of assumption to perform all of the obligations of the
Seller hereunder (including the Seller’s obligations under Section 5.01 incurred at any time prior to or after
the date of such assumption), shall be the successor to the Seller under this Sale Agreement without further act on the part
of any of the parties to this Sale Agreement; provided, however, that (i) immediately after giving effect to such
transaction, no representation, warranty or covenant made pursuant to Article III or Article IV shall have been
breached and, if the Seller is the Servicer, no Servicer Default and no event which, after notice or lapse of time, or both,
would become a Servicer Default shall have occurred and be continuing, (ii) the Seller shall have delivered to the Issuer and
the Indenture Trustee an Officer’s Certificate and an Opinion of Counsel from external counsel stating that such
consolidation, conversion, merger, division or succession and such agreement of assumption complies with this Section
5.02 and that all conditions precedent, if any, provided for in this Sale Agreement relating to such transaction have
been complied with, (iii) the Seller shall have delivered to the Issuer, the Indenture Trustee and each Rating Agency an
Opinion of Counsel from external counsel of the Seller either (A) stating that, in the opinion of such counsel, all filings
to be made by the Seller and the Issuer, including filings with the PSCW pursuant to the Statute and the applicable UCC, have
been executed and filed that are necessary to fully maintain the respective interests of the Issuer and the Indenture Trustee
in the Environmental Control Property and reciting the details of such filings or (B) stating that, in the opinion of such
counsel, no such action shall be necessary to maintain such interests, (iv) the Seller shall have delivered to the Issuer,
the Indenture Trustee and each Rating Agency an Opinion of Counsel from independent tax counsel stating that, for U.S.
federal income tax purposes, such consolidation, conversion, merger, division or succession and such agreement of assumption
will not result in a material adverse U.S. federal income tax consequence to the Issuer or the Holders of Environmental Trust
Bonds and (v) the Seller shall have given each Rating Agency prior written notice of such transaction.  When any Person
(or more than one Person) acquires the properties and assets of the Seller substantially as a whole or otherwise becomes the
successor, by merger, conversion, consolidation, sale, transfer, lease or otherwise, to all or substantially all the assets
of the retail electric distribution business of the Seller in accordance with the terms of this Section 5.02, then,
upon satisfaction of all of the other conditions of this Section 5.02, the preceding Seller shall automatically and
without further notice be released from all of its obligations hereunder.

 

    15

     

    

 

SECTION 5.03.         
Limitation on Liability of Seller and Others. The Seller and any director, officer, employee or agent of the Seller
may rely in good faith on the advice of counsel or on any document of any kind, prima facie properly executed and submitted by
any Person, respecting any matters arising hereunder. Subject to Section 4.07, the Seller shall not be under any obligation
to appear in, prosecute or defend any legal action that is not incidental to its obligations under this Sale Agreement and that
in its opinion may involve it in any expense or liability.

MISCELLANEOUS PROVISIONS

 

SECTION 6.01.         
Amendment. This Sale Agreement may be amended in writing by the Seller and the Issuer with ten Business Days’
prior written notice given to the Rating Agencies, but without the consent of any of the Holders, (i) to cure any ambiguity, to
correct or supplement any provisions in this Sale Agreement or for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions in this Sale Agreement or of modifying in any manner the rights of the Holders; provided,
however, that such action shall not, as evidenced by an Officer’s Certificate delivered to the Issuer and the Indenture
Trustee, adversely affect in any material respect the interests of any Holder or (ii) to conform the provisions hereof to the description
of this Sale Agreement in the Prospectus.

 

In addition, this Sale Agreement may be
amended in writing by the Seller and the Issuer with (i) the prior written consent of the Indenture Trustee, (ii) the satisfaction

of the Environmental Trust Bonds, the consent of a majority of the Holders of each affected Tranche of Environmental Trust Bonds.
In determining whether a majority of Holders have consented, Environmental Trust Bonds owned by the Issuer, Seller or any Affiliate
of the Issuer or Seller shall be disregarded, except that, in determining whether the Indenture Trustee shall be protected in relying
upon any such consent, the Indenture Trustee shall only be required to disregard any Environmental Trust Bonds it actually knows
to be so owned. Promptly after the execution of any such amendment or consent, the Issuer shall furnish copies of such amendment
or consent to each of the Rating Agencies.

 

It shall not be necessary for the consent
of Holders pursuant to this Section to approve the particular form of any proposed amendment or consent, but it shall be sufficient
if such consent shall approve the substance thereof.

 

Notwithstanding the foregoing, in no event
shall this Sale Agreement be amended without the approval of the PSCW if (1) such approval is required pursuant to Wis. Stat. §
196.52, or (2) such amendment would increase the ongoing Financing Costs of the Issuer.

FORM OF BILL OF SALE

 

See attached

BILL OF SALE

 

This Bill of Sale is being delivered pursuant
to the Environmental Control Property Purchase and Sale Agreement, dated as of May 12, 2021 (the “Sale Agreement”),
by and between Wisconsin Electric Power Company (the “Seller”) and WEPCo Environmental Trust Finance I, LLC
(the “Issuer”). All capitalized terms used but not otherwise defined herein shall have the respective meanings
ascribed to such terms in the Sale Agreement.

 

In consideration of the Issuer’s delivery
to or upon the order of the Seller of $113,507,309, the Seller does hereby irrevocably sell, assign and otherwise transfer to the
Issuer, without recourse or warranty, except as set forth in the Sale Agreement, all right, title and interest of the Seller in,
to and under the Environmental Control Property created or arising under the Financing Order dated November 17, 2020 issued by
the Public Service Commission of Wisconsin under the Statute (such sale, assignment and transfer of the Environmental Control Property
includes, to the fullest extent permitted by the Statute, the right to impose, collect and receive Environmental Control Charges
and the assignment of all revenues, collections, claims, rights, payments, money or proceeds of or arising from the Environmental
Control Charges related to the Environmental Control Property, as the same may be adjusted from time to time). Such sale, assignment
and transfer of the Environmental Control Property is hereby expressly stated to be a sale or other absolute transfer and, pursuant
to Section 196.027(5)(c) of the Statute and the Financing Order, shall constitute a sale and absolute transfer of all of the Seller’s
right, title and interest, in, to and under, and not a pledge of, or secured transaction relating to, the Seller’s right,
title and interest, in, to and under the Environmental Control Property. The preceding sentence is the statement referred to in
Section 196.027(5)(c) of the Statute. The Seller and the Issuer agree that after giving effect to the sale, assignment and transfer
contemplated hereby the Seller has no right, title or interest in, to or under the Environmental Control Property to which a security
interest could attach because (i) it has sold, assigned and transferred all right, title and interest in and to the Environmental
Control Property to the Issuer, and (ii) as provided in Section 196.027(5)(c) of the Statute, after such transfer the Environmental
Control Property is not subject to any claims of the Seller or the Seller’s creditors, other than creditors holding a prior
security interest in the Environmental Control Property perfected under Section 196.027(5)(b) of the Statute. If such sale, assignment
and transfer is held by any court of competent jurisdiction not to be an absolute transfer as provided in Section 196.027(5)(c)
of the Statute, then such sale, assignment and transfer shall be treated as a pledge of the Environmental Control Property and
as the creation of a security interest (within the meaning of the Statute and the applicable UCC) in the Environmental Control
Property and, without prejudice to its position that it has absolutely transferred all of its rights in the Environmental Control
Property to the Issuer, the Seller hereby grants a security interest in the Environmental Control Property to the Issuer (and to
the Indenture Trustee for the benefit of the Secured Parties) to secure their respective rights under the Basic Documents to receive
the Environmental Control Charges and all other Environmental Control Property.

 

The Issuer does hereby purchase the Environmental
Control Property from the Seller for the consideration set forth in the preceding paragraph.

 

    22

     

    

 

The Seller and the Issuer each acknowledge
and agree that the purchase price for the Environmental Control Property sold pursuant to this Bill of Sale and the Sale Agreement
is equal to its fair market value at the time of sale.

 

The Seller confirms that (i) each of the
representations and warranties on the part of the Seller contained in the Sale Agreement are true and correct in all respects on
the date hereof as if made on the date hereof and (ii) each condition precedent that must be satisfied under Section 2.02 of the
Sale Agreement has been satisfied upon or prior to the execution and delivery of this Bill of Sale by the Seller.

 

This Bill of Sale may be executed by the
parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts
shall together constitute but one and the same instrument.

 

This
Bill of Sale shall be construed in accordance with the laws of the State of Wisconsin, without reference to its conflict of law
provisions, and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with such law.

 

    23

     

    

 

IN WITNESS WHEREOF, the Seller and the Issuer
have duly executed this Bill of Sale as of this 12th day of May, 2021.
