of the need to file such a return first in writing in case there is any disagreement about whether Sales Taxes are owed and work
in good faith to resolve any disagreement.



(d)          The
Parties agree that prior to the Closing, none of the Parties will negotiate with any taxing authority regarding tax rates or structures
for the Project without the prior written reasonable consent of the other Parties, and that if such consent to negotiate is provided,

for actions taken pursuant to Section 6.11, enter into, amend, modify, cancel or terminate any (i) Contract which would be a material
Purchased Contract or (ii) Land Contract, in each case, in a manner that would have an adverse impact on the ownership or operation
of the Project or increase the liability of Buyer under such Land Contract or Contract after Closing; provided, that Sellers
may enter into Land Contracts that are in substantially the same form as the Land Contracts provided to Buyer for review prior
to the date of this Agreement (so long as such new Land Contracts have a term of at least 60 years from the Commercial Operation
Date and Seller uses commercially reasonable efforts to have a lease term of 99 years from the Commercial Operation Date, and further
such new Land Contracts shall conform to all applicable Laws, including the requirements of North Dakota Century Code, Chapter

or other independent certified public accountants of recognized international standing reasonably acceptable to Buyer, which opinion
shall state that such financial statements present fairly, in all material respects, the financial condition of EDF-EN and its
results of operations and cash flows and have been prepared in conformity with International Financial Reporting Standards, and
that the examination of such accountants in connection with such financial statements has been made in accordance with generally
accepted auditing standards, and that such audit provides a reasonable basis for such opinion in the circumstances and (ii) within
90 days after the close of the second quarterly period of each of the fiscal years of EDF-EN, an unaudited consolidated balance

Section 6.5           Efforts;
Consents; Regulatory and Required Seller Approval.



(a)          Each
Party will use diligent and commercially reasonable efforts to (i) take, or cause to be taken, all appropriate action, and do,
or cause to be done, all things necessary, proper or advisable under applicable Laws or otherwise to promptly consummate and make
effective the transactions contemplated by this Agreement, including cooperating with the other Parties; (ii) obtain all authorizations,
consents, orders and approvals of, and give all notices to and make all filings with, all Governmental Authorities and other third
parties that may be or become necessary for the performance of its obligations under this Agreement and the consummation of the

Contract or Purchased Contract to which Sellers is bound or by which any of Seller’s assets or properties are bound, including
the Regulatory Approvals and (iii) satisfy all conditions to such Party’s obligations under this Agreement. Notwithstanding
the foregoing or anything to the contrary set forth in this Agreement, in connection with obtaining such authorizations, consents,
orders and approvals from Governmental Authorities or third parties, no Party will be required to make payments (other than the
payment of routine filing fees), commence legal or regulatory proceedings (other than the Regulatory Approvals) or agree to modifications
of the terms and conditions of any agreements with third parties or Permits. Nothing in this Section 6.5 shall require any
Party to (A) consent to any action or omission by the other Party or its Affiliates that would be inconsistent with Section 6.3
absent such consent or (B) agree to amend or waive any provision of this Agreement. Each Party shall reasonably cooperate with
the other Party in performing the obligations required by this Section 6.5(a), including the negotiation, execution, and assignment
of Land Contracts, Purchased Contracts and other agreements related to the Project. The Parties will not take any action that is
reasonably likely to have the effect of unreasonably delaying, impairing or impeding the receipt of any required authorizations,
consents, orders or approvals.



(b)          Within
30 days following the execution of this Agreement, Sellers shall send the USFWS a letter, email, or other written communication
informing the USFWS that (i) Sellers and Buyer have entered into an agreement under which Buyer will purchase the Project from
Sellers, (ii) the Parties intend to proceed with construction of the Project, and (iii) the Parties do not intend to obtain an
incidental take permit in connection with the Project. Seller must allow Buyer a reasonable opportunity to review and comment on
any such written communication prior to submission, and any proposed edits shall not be unreasonably rejected.



- 36 -







(c)          From
time to time, but no less often than once a year following the execution of this Agreement and prior to the Closing, Sellers shall
send the USFWS a letter, email, or other written communication informing the USFWS in summary form on new developments relating
to the Project. Seller must allow Buyer a reasonable opportunity to review and comment on any such written communication prior
to submission, and any proposed edits shall not be unreasonably rejected.



(d)          At
least 30 days prior to the Closing Date, Sellers shall submit the final version of the Bird and Bat Conservation Strategy to the
USFWS (and provide a copy thereof to Buyer). Sellers must allow Buyer a reasonable opportunity to comment on the Bird and Bat Conservation
Strategy prior to submission, and any proposed edits shall not be unreasonably rejected. Sellers agree that the comments set forth
in Schedule 6.5(d) are reasonable and shall be reflected in the final Bird and Bat Conservation Strategy.



Section 6.6           Public
Announcements. Subject to a Party’s reasonable judgment that it is required by Law or by the rules of a national securities
exchange to make such disclosure, no Party shall issue any public announcement or other statement with respect to this Agreement
or the transactions contemplated hereby without the prior consent of the other Parties. Additionally, subject to Buyer providing
Sellers with advance written notice and an opportunity to review and comment on such disclosures, each Seller hereby consents to
the disclosure of confidential information regarding the Project and its current status in public filings and informal communications
with regulators to be made by Buyer, but only to the extent that such confidential information is reasonably necessary or required
(based on the advice of counsel) in connection with seeking approval of the transaction contemplated by this Agreement and in developing
the Project; and hereby waives any confidentiality provisions relating thereto currently in effect. Notwithstanding the immediately
preceding sentence, Buyer shall not make any disclosure of confidential information related to the Prime Subcontract or Turbine
Supply Agreement; provided, that Buyer may disclose such confidential information if it is required by a regulator and Buyer
uses reasonable efforts to seek trade secret protection.



Section 6.7           Further
Assurances. Subject to the terms and conditions of this Agreement, at any time or from time to time after the Closing, at any
Party’s request and without further consideration, the other Parties will execute and deliver to such Party such other instruments
of sale, transfer, conveyance, assignment and confirmation, provide such materials and information and take such other actions
as such Party may reasonably request in order to consummate the transactions contemplated by this Agreement.



- 37 -







Section 6.8           Updated
Schedules. From time to time prior to and up to ten (10) Days prior to the Closing Date, a disclosing Party shall provide written
notice to the other Party of any fact, matter, condition, event or circumstance that occurs following the date of this Agreement
and that, individually or in the aggregate, renders the disclosing Party unable, without amending the Schedules, to satisfy their
condition precedent under Article 7 (each, an “Update”). In the event the other Party does not terminate
this Agreement pursuant to Article 8 following delivery of such Update, the disclosing Party shall be permitted to update
the applicable Schedule(s) to properly reflect the fact, matter, condition, event or circumstance disclosed to the other Party
in such Update, and all of the disclosing Party’s representations and warranties set forth in this Agreement made following
the Update shall be subject to the Schedules attached hereto, as modified or amended by such an Update, for purposes of satisfying
the conditions to Closing set forth in Article 7; provided,further, that, if the Closing occurs, such Update
shall not be deemed to have modified the Schedules for purposes of determining whether there has been a breach of the applicable
representations and warranties related to Sellers’ indemnification obligations in Section 9.2. Notwithstanding the foregoing,
to the extent Buyer has a claim for indemnification in accordance with Section 9.2 resulting from a breach of the applicable
representations and warranties based on the fact, matter, condition, event or circumstance described in the Update, Buyer shall
provide Seller with written notice of such claim in accordance with Article 9 (such notice, an “Update Indemnification
Notice”) within ten (10) days of receiving the Update, which notice shall include a description of the claim and
Buyer’s good faith estimate of the amount of such claim; provided, that, in the event that Buyer delivers an Update
Indemnification Notice within such ten (10)-day period, Seller shall have a termination right in accordance with Section 8.1(l).
If Buyer fails to deliver an Update Indemnification Notice within such ten (10)-day period, then Buyer be deemed to have irrevocably
waived such claim.



Section 6.9           Representations
and Warranties. Subject to Section 5.7 of this Agreement, Buyer shall have the right to rely on the representations set forth
in Article 4 regardless of (a) any due diligence done by Buyer and its representatives and (b) any knowledge or information
known or available to Buyer from Sellers or any other source.



Section 6.10         Interconnection
Costs.



(a)          The
Parties hereby agree to cooperate in good faith to evaluate interconnection studies and share information related to the timing
and costs of the Project interconnection. Without limiting the generality of the foregoing, Sellers shall (i) promptly upon receipt
thereof, provide copies of all studies and other communications received from MISO or any other RTO or transmission owner with
respect to MISO Interconnection Queue Request J457; (ii) promptly provide Buyer with copies all drafts of the New GIA and any facility
construction agreements received from MISO or the applicable transmission owner prior to Closing; (iii) provide Buyer a period
of not less than ten (10) days following Buyer’s receipt from Sellers of copies of such draft documents to review and comment
on such draft documents; and (iv) allow Buyer to participate in any telephone calls or negotiating sessions regarding the same.



(b)          If
the Existing GIA is assigned to Buyer at Closing pursuant to Section 2.1, then (i) Sellers shall bear, and Buyer shall have
no obligation with respect to, the historic costs associated with the Existing GIA prior to the Closing, (ii) Buyer shall bear
100% of any additional costs assessed by MISO with respect to the Existing GIA following the Closing, and (iii) Sellers shall be
entitled to any MISO refunds arising from the pre-Closing termination or withdrawal of MISO Interconnection Queue Request J457.



- 38 -







(c)          From
time to time as the study process associated with MISO Interconnection Queue Request J457 progresses, Buyer and Sellers will in
good faith consider whether the NRIS Interconnection Costs or the ERIS Interconnection Costs will be lower, and if the ERIS Interconnection
Costs are lower, consider whether Sellers should amend MISO Interconnection Queue Request J457 to request “ERIS;” provided,
that Buyer acknowledges and agrees that the final decision as to whether to amend MISO Interconnection Queue Request J457 shall
be in the sole discretion of Sellers; provided, further, that if (i) Buyer requests that Sellers amend MISO Interconnection
Queue Request J457 to request “ERIS,” (ii) at the time Buyer requests “ERIS,” the ERIS Interconnection
Costs are estimated to be lower than the NRIS Interconnection Costs, and (iii) Sellers do not amend MISO Interconnection Queue
Request J457 to request “ERIS” prior to the expiration of the time during which such amendment is permitted, then,
notwithstanding Sections 6.10(d) and (e), Sellers agree to pay all Interconnection Costs in excess of the ERIS Interconnection
Costs.



(d)          Subject
to Section 6.10(c), if, following completion of all system impact and facilities studies, the Estimated Interconnection Costs exceed
$[**] (such excess amount, the “Excess Interconnection Costs”), this Agreement shall automatically terminate
within thirty (30) days after such determination unless any Party provides written notice to the other Parties within such 30-day
period that it will pay such Excess Interconnection Costs. For the avoidance of doubt, the Parties agree that the Estimated Interconnection
Costs cannot be determined prior to completion of all system impact and facilities studies associated with MISO Interconnection
Queue Request J457.



(e)          Subject
to Section 6.10(c), if the New GIA is assigned to Buyer at Closing pursuant to Section 2.1, then the responsibility for the
Interconnection Costs shall be as follows:



(i)          Buyer
shall pay all Interconnection Costs up to the base cost of $[**].



(ii)         If
the Interconnection Costs are between $[**] and $[**], such incremental costs shall be paid one-half by Buyer and one-half by Sellers.



(iii)        If
the Interconnection Costs exceed an amount equal to the higher of (A) $[**] or (B) any higher amount agreed to be paid by a Party
pursuant to Section 6.10(d)), then Buyer will pay the amount of such excess.



(iv)         If
Sellers make a cash payment of any portion of the Interconnection Costs owed by Buyer pursuant to this Section 6.10(e) prior to
Closing, and have not received a refund of such amount, Buyer shall reimburse Sellers for such amounts at Closing. If Sellers subsequently
receive a refund of any amounts reimbursed by Buyer, Sellers shall pay such refund to Buyer. If Buyer pays any portion of the costs
associated with the interconnection studies for MISO Interconnection Queue Request J457 (whether before or after Closing), Sellers
shall promptly reimburse Buyer for such amount upon request. Any difference between the Estimated Interconnection Costs and the
actual Interconnection Costs incurred shall be trued up between the Parties at the Commercial Operation Date; provided, that (A)
subject to Sections 6.10(c) and (d), following the Closing Buyer shall bear all Excess Interconnection Costs and (B) following
the Commercial Operation Date, Buyer shall (1) bear any new interconnection costs in addition to those known and allocated between
the parties before such date and (2) be entitled to receive 100% of any refunds related to the New GIA that aren’t known
as of the Commercial Operation Date.

by such Seller or its Affiliates of any such obligations, Buyer shall, in addition to any and all other rights and remedies that
may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an

by this Agreement. In the event that any covenant contained in this Section 6.12 should ever be adjudicated to exceed the
time, geographic, product or service or other limitations permitted by applicable Law in any jurisdiction, then any court is expressly

of Credit; Guaranty.



(a)          To
fulfill Sellers’ full and timely payment obligations hereunder, Sellers shall cause (i) EDF-EN to execute and deliver to
Buyer contemporaneous with the execution of this Agreement, and maintain in full force and effect, the EDF-EN Guaranty, which shall
be subject to the limitations set forth therein, including the EDF-EN Guaranty Expiration; (ii) on or before January 1, 2018, either
(x) EDF-EN to execute and deliver to Buyer and maintain in full force and effect, the Construction Period Guaranty, or (y) the
execution and delivery to Buyer of the Project Surety Bond, in each case subject to the limitations set forth therein, including
the Construction Period Guaranty Expiration; and (iii) EDF-RE to execute and deliver to Buyer on or prior to the Project Substantial
Completion Date, and maintain in full force and effect, the Post-Construction Guaranty, subject to the limitations set forth therein,
including the Post-Construction Guaranty Expiration. Upon the occurrence of a Credit Trigger Event with respect to a Guarantor,
Sellers shall provide Buyer with a Backup LOC with respect to each Guaranty issued by such Guarantor and outstanding at the time
of such Credit Trigger Event. Each such Backup LOC, if issued, shall secure (x) Guarantor’s obligations under the Guaranty
with respect to which such Backup LOC was issued, (y) Sellers’ payment obligations under this Agreement, including all indemnity
and liquidated damages obligations hereunder, and (z) EDF-USD’s payment obligations under the TEPC, including performance
through the end of applicable Infrastructure Facilities Warranty Periods (as defined in the TEPC). The Backup LOC shall terminate
on the sixth (6th) anniversary of the Project Substantial Completion Date. Buyer shall be entitled to draw on such letter of credit
for any uncured breach by Sellers of this Agreement (to the extent Buyer is entitled to indemnification for Losses arising from
such breach under Article 9), by EDF-USD under the TEPC or by the Guarantor of the applicable Guaranty. For the avoidance of doubt,
the EDF-EN Guaranty, the Construction Period Guaranty, the Post-Construction Guaranty, and the Backup LOC(s), each referenced in
this Section 6.13(a), are the same agreements as those referenced in the TEPC, and not in addition to such agreements.



- 41 -







(b)          Upon
the occurrence of a Credit Trigger Event with respect to Buyer, Buyer shall provide Sellers with an irrevocable letter of credit
in the form attached as Exhibit 4.1.2 to the TEPC, issued by a Qualified Institution, with a drawable amount equal to Fifteen
Million and 00/100 Dollars ($15,000,000). Such letter of credit, if issued, shall secure Buyer’s payment obligations, including
Buyer’s indemnity obligations, hereunder. Sellers shall be entitled to draw on such letter of credit for any uncured breach
by Buyer of this Agreement.



Section 6.14         Title
Commitment; Survey; Title Policy.



(a)          Buyer
has reviewed the Survey dated as of October 21, 2016 and the Title Commitment dated as of September 15, 2016 (collectively, the
“Existing Title Evidence”) and accepts those documents and exceptions identified on such Title Commitment,
except as identified in that certain title objection letter dated November 15, 2016 (the “Title Objection Letter”)
attached as Schedule 6.14(a) hereto.  The matters, documents and exceptions not objected to in the Title Objection
Letter shall be Permitted Liens (“Existing Permitted Exceptions”).  Based on Buyer’s review
of the Existing Title Evidence, the Title Objection Letter also contains Buyer’s objections to, and Buyer’s proposed
curative measures for, the Existing Title Evidence (“Existing Title Objections”).  Sellers have
agreed to cure the Existing Title Objections prior to Closing as set forth in the Title Objection Letter.



(b)          Notwithstanding
Section 6.14(a) or Section 6.14(c), Buyer reserves the right to object to the Existing Permitted Exceptions based upon its review
of the then current Title Commitment and updated Survey delivered in connection with Closing pursuant to Section 6.14(c) below,
the Site Plan, any changes in Laws, and the requirements of the Permits, provided, however, that such objections must result from
changes in the Title Commitment, updated Survey, updated Site Plan or Permits which address matters that would materially detract
from the value or materially interfere with the construction, operation or maintenance of the Project as contemplated in the Site
Plan.



(c)          At
least ninety (90) days prior to Closing, Sellers shall cause the Title Company to deliver to Buyer an updated Survey, which updated
Survey shall depict the final Project layout pursuant to the Site Plan and include current wetland information and cultural data,
and current Title Commitment, along with legible copies of all documents identified on such Title Commitment (“Title
Evidence”). If the Title Evidence shows any new documents, new title exceptions or new survey issues not identified
on the Existing Title Evidence (collectively, the “New Exceptions”), then Buyer shall have the right
to reasonably approve or disapprove such New Exceptions. Within twenty (20) days after receipt of the last of the Title Evidence,
Buyer shall provide Sellers with a title objection letter setting forth Buyer’s objections to items identified in the Title
Evidence (“Updated Title Objection Letter”), other than, except as provided in Section 6.14(b), the Existing
Permitted Exceptions (together with the Existing Title Objections, “Title Objections”). Sellers will
use their commercially reasonable efforts to cure each Title Objection. Except for Permitted Liens, prior to the Closing, all Title
Objections shall have been eliminated as an exception to the Title Policy, committed to be insured over by the Title Company in
the Title Policy in form and substance reasonably acceptable to Buyer, or otherwise cured to Buyer’s reasonable satisfaction;
provided that any fee mortgage of landowners under the Land Contracts, manure easement or tenant lease that is superior
to the interest of Sellers and with respect to which a non-disturbance agreement in form and substance acceptable to Buyer has
been obtained and delivered to Buyer at or prior to Closing shall be considered Permitted Liens at Closing.



- 42 -







(d)          At
Closing, Sellers shall cause the Title Company to issue the Title Policy. Sellers shall pay for the Survey (and any amendments,
updates and supplements thereto) and the costs and search fees for the Title Commitments (and any amendments, updates and supplements
thereto) and all recording charges and expenses incurred in connection with recording any Land Contract (or amendments or memoranda
thereof) and any curative documents. Buyer shall pay all Title Policy premiums and the cost to record the Deed.



(e)          General
real estate Taxes and installments of special assessments for the Owned Real Property shall be pro-rated as of the Closing Date,
on a per diem basis based on the latest available data and in accordance with local custom, which proration will be final as of
the Closing Date and not subject to recalculation after the Closing.



Section 6.15         Site
Plan. Promptly following completion, and in any case prior to January 15, 2017, Sellers shall deliver the final Site Plan to
Buyer. The Site Plan shall be reviewed by Buyer in collaboration with Sellers for a period of thirty (30) days following delivery
thereof by Sellers (the “Review Period”). In the event Buyer fails to provide comments to Sellers prior to the expiration
of the Review Period, the Site Plan shall be deemed approved by Buyer as of the date of delivery thereof by Sellers. In the event
Buyer provides comments on the Site Plan to Sellers prior to the termination of the Review Period, Sellers shall review such Buyer
comments and include them in the Site Plan so long as such Buyer comments do not result in an increase in Sellers’ costs
or are consistent with Prudent Industry Practices. To the extent that Buyer still would like changes made that result in an increase
in Sellers’ costs and which are not consistent with Prudent Industry Practices, Buyer shall be responsible for any such costs
arising from those design changes requested by Buyer. Sellers shall deliver to Buyer a revised Site Plan that addresses Buyer’s
comments as soon as reasonably possible after receipt of Buyer’s comments and Buyer shall approve or disapprove such revised
Site Plan in accordance with the same procedures. Notwithstanding the foregoing, Sellers shall (a) use reasonable efforts and employ
best practices to avoid impacts to aquatic features determined to be jurisdictional under the federal Clean Water Act, and in no
case shall the impact to such jurisdictional waters require authorization from the US Army Corps of Engineers, (b) ensure that
the Site Plan conforms in all material respects to all recommendations in the Bird and Bat Conservation Strategy, (c) use reasonable
efforts and employ best practices to avoid impacts to areas which are enrolled as acreage under the Conservation Reserve Program
except for areas with respect to which Sellers have secured authorization for permissive use consistent with standard industry
practices from all relevant agencies, including the United States Department of Agriculture, (d) not locate WTGs in areas subject
to Waterfowl Habitat Protection Easements, and (e) not locate any other facilities in areas subject to Waterfowl Habitat Protection
Easements unless it has obtained appropriate consents from USFWS (for initial construction and all future maintenance and repair
activities) and written confirmation from the USFWS that such consents will not create a federal nexus and require consultation
under the Endangered Species Act.

Section 6.16         5%
Safe Harbor Turbines. In the event that some or all of the 5% Safe Harbor Turbines designated in the Daughter Contract are
determined prior to the Closing Date not to qualify the Project for 100% PTCs due to a failure of one or more of the representations
in Section 4.16 to be true, then to the extent owned by Sellers or any Affiliates of Sellers, Sellers shall, or shall cause their
Affiliates to, allocate other Vestas 2.0MW V110 wind turbine components to the Project such that the Project will qualify for 100%
PTCs.

by the Indemnified Party in the year any indemnification payment for such Losses was received (or an earlier year) arising from
the receipt of any such payment hereunder (grossed up for such increase) and will be decreased to take into account any net tax
benefit realized by the Indemnified Party in the year the Losses were incurred or paid (or an earlier year) arising from the incurrence

Cap. Notwithstanding the foregoing, the aggregate amount of Losses for which an Indemnifying Party shall be liable pursuant
to this Article 9 shall not exceed an amount equal to 50% of the Purchase Price; provided, that such limitation
shall not apply to Losses arising out of (i) Indemnity Claims under Section 9.2(b) or Section 9.3(b) which shall not exceed
the Purchase Price, and Section 9.2(c) which shall be limited in accordance with Section 9.4(e), (ii) Indemnity Claims
based on fraud or willful misconduct or (iii) Indemnity Claims under Section 9.3(c) based on the failure of Buyer to pay
the Purchase Price.



(e)          PTC
Cap. Notwithstanding the foregoing, the aggregate amount of Losses for which Sellers shall be liable for Indemnity Claims
under Section 9.2(c) arising from breaches of the PTC Representations set forth in Section 4.16 (after adjustment pursuant
to Section 9.4(b)) shall not exceed an amount equal to one hundred million dollars ($100,000,000).



(f)          Tax
Treatment. Any indemnity payment made pursuant to this Agreement will be treated as an adjustment to the Purchase Price for
Tax purposes, unless an audit or other administrative or judicial action with respect to the Indemnified Party causes any such
payment not to constitute an adjustment to the Purchase Price for U.S. federal income tax purposes.



(g)          NOTWITHSTANDING
ANYTHING TO THE CONTRARY IN THIS SECTION 9.4, THE PARTIES RETAIN ALL RIGHTS AND REMEDIES AT LAW WITH RESPECT TO FRAUD OR ANY WILLFUL
MISCONDUCT.



(h)          EXCEPT
IN THE CASE OF AN INDEMNITY CLAIM UNDER SECTION 9.2(C), IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY LOST OR PROSPECTIVE PROFITS
NOR ANY PUNITIVE, EXEMPLARY, CONSEQUENTIAL, INCIDENTAL OR INDIRECT LOSSES OR DAMAGES (IN TORT, CONTRACT OR OTHERWISE) UNDER OR
IN RESPECT TO THIS AGREEMENT, OTHER THAN SUCH DAMAGES THAT ARISE OUT OF A CLAIM MADE BY A THIRD PARTY AGAINST BUYER OR SELLERS,
AS APPLICABLE.



Section 9.5           Procedures
for Third Party Claims.



(a)          Promptly
after receipt by an Indemnified Party of notice of the commencement of any Action by a third party (a “Third Party
Claim”) with respect to any matter for which indemnification is or may be owing pursuant to Section 9.2 or 9.3
hereof, the Indemnified Party will give notice thereof to the Indemnifying Party, provided, however, that the failure
of the Indemnified Party to notify the Indemnifying Party will not relieve the Indemnifying Party of any of its obligations hereunder,
except to the extent that the Indemnifying Party demonstrates that the defense of such Third Party Claim has been actually prejudiced
by the Indemnified Party’s failure to give such notice.







- 52 -







(b)          If
any Action referred to in Section 9.5(a) is brought against an Indemnified Party and the Indemnified Party gives notice to
the Indemnifying Party of the commencement of such Action, the Indemnifying Party will be entitled to participate in such Action,
and (unless (x) the Indemnifying Party is also a party to such Action and the Indemnified Party determines in good faith that
joint representation would be inappropriate upon the advice of outside counsel that a conflict of interest exists between the Indemnified
Party and the Indemnifying Party with respect to such Action, or (y) the Indemnifying Party fails to provide reasonable assurance
to the Indemnified Party of its financial capacity to defend such Action and provide indemnification with respect to such Action)
may assume the defense of such Action with counsel satisfactory to the Indemnified Party and, after notice from the Indemnifying
Party to the Indemnified Party of its election to assume the defense of such Action, the Indemnifying Party will not, as long as
it diligently conducts such defense, be liable to the Indemnified Party under this Section 9.5 for any fees of other counsel
with respect to the defense of such Action, in each case subsequently incurred by the Indemnified Party in connection with the
defense of such Action.



(c)          If
the Indemnifying Party is entitled to and assumes the defense of an Action, no compromise or settlement of such claims or Action
may be effected by the Indemnifying Party without the Indemnified Party’s written consent (which shall not be unreasonably
withheld) unless (i) there is no finding or admission of any violation of Law or any violation of the rights of any Person
and no effect on or grounds for the basis of any other Claims that may be made against the Indemnified Party, and (ii) the
sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and the Indemnified Party will have no
Liability with respect to any compromise or settlement of such claims or Action effected without Indemnified Party’s written
consent. Notwithstanding the assumption by the Indemnifying Party of the defense of any Claim or Action, the Indemnified Party
will be permitted to join in such defense and to employ counsel at its own expense. If notice pursuant to Section 9.5(a) is
given to an Indemnified Party of the commencement of any Action and the Indemnifying Party does not, within ten (10) Business Days
after such Indemnified Party’s notice is given, give notice to the Indemnified Party of its election to assume the defense
of such Action, the Indemnifying Party will be bound by any determination made in such Action or any compromise or settlement effected
by the Indemnified Party.



(d)          Notwithstanding
the foregoing, if the Indemnified Party determines in good faith that there is a reasonable probability that an Action may adversely
affect the Indemnified Party or its Affiliates other than as a result of monetary Losses for which it would be entitled to indemnification
under this Agreement, the Indemnified Party may, by notice to the Indemnifying Party, assume the exclusive right to defend, compromise
or settle such Action, but the Indemnifying Party will not be bound by any compromise or settlement effected without its written
consent (which may not be unreasonably withheld).



- 53 -







(e)          The
Indemnifying Party and the Indemnified Party agree to provide each other with reasonable access during regular business hours to
the properties, books and records and Representatives of the other, as reasonably necessary in connection with the preparation
for an existing or anticipated Action involving a Third Party Claim and its obligations with respect thereto pursuant to this Article 9.



Section 9.6           Indemnification
Procedures. The following procedures will apply to any claim for indemnification by Buyer Group or the Seller Group that does
not involve a Third Party Claim:



(a)          Notice
of Claim. A Notice of Claim will be given as soon as practicable, but in no event later than sixty (60) days, after the Indemnified
Party determines that it is or may be entitled to indemnification pursuant to this Agreement; provided, however,
that failure to provide notice will not prejudice the Indemnified Party’s right to indemnity, except to the extent the Indemnifying
Party is irrevocably prejudiced. Notice of Claim will be made as follows:



(i)          in
the case of any Indemnity Claim by any member of Buyer Group, by Buyer to Sellers at the address and in the manner provided in
Section 10.1 (Notices). Buyer will be the Indemnified Party with respect to Indemnity Claims pursuant to Section 9.2,
and no liability in respect of any such Indemnity Claim will be contested, settled, admitted, litigated or otherwise dealt with
by or on behalf of Buyer Group for this purpose by any person other than Buyer; and



(ii)         in
the case of any Indemnity Claim by any member of the Seller Group against Buyer, by Sellers to Buyer at the address and in the
manner provided in Section 10.1 (Notices). Sellers will be the Indemnified Party with respect to Indemnity Claims pursuant
to Section 9.3, and no liability in respect of any such Indemnity Claim will be contested, settled, admitted, litigated or
otherwise dealt with by or on behalf of the Seller Group for this purpose by any person other than Sellers.



(b)          Dispute
Notice. If the Indemnifying Party disputes (x) its obligation to indemnify the Indemnified Party in respect of any Indemnity
Claim set forth in a Notice of Claim, or (y) the Indemnity Claim Amount set forth in a Notice of Claim, a dispute notice (“Dispute
Notice”) will be given as soon as practicable, but in no event later than forty-five (45) days, after the
Notice of Claim is given, as follows:



(i)          in
the case of any Indemnity Claim by any member of Buyer Group against Sellers, a Dispute Notice may be given only by Sellers, and
if given, will be sent by Sellers to Buyer at the address and in the manner provided in Section 10.1 (Notices); and



(ii)         in
the case of any Indemnity Claim by any member of the Seller Group against Buyer, a Dispute Notice may be given only by Buyer, and
if given, will be sent by Buyer to Sellers at the address and in the manner provided in Section 10.1 (Notices).



- 54 -







(A)         If
no Dispute Notice is given within such thirty (30) day period, the validity of the claim for indemnification and the
Indemnity Claim Amount, each as set forth in the Notice of Claim, will be deemed to be agreed, effective on the first (1st) day
following such thirty (30) day period, and the Indemnity Claim Amount set forth in the Notice of Claim will immediately
be an “Indemnity Amount Payable” of the relevant Indemnifying Party.



(B)         If
a Dispute Notice is given within such thirty (30) day period, then:



(1)         The
portion, if any, of the Indemnity Claim Amount which is not disputed in the Dispute Notice will immediately be an Indemnity Amount
Payable of the relevant Indemnifying Party.



(2)         Buyer
and Sellers will negotiate in good faith to settle the dispute, and the portion, if any, of the Indemnity Claim Amount which Buyer
and Sellers agree in writing is payable will immediately be an Indemnity Amount Payable of the relevant Indemnifying Party.



(3)         If
Buyer and Sellers are unable to resolve any portion of the Indemnity Claim Amount within two (2) months following the date the
Dispute Notice is given, either Buyer or Sellers may initiate proceedings specified in Section 10.12 (Governing Law; Venue;
and Jurisdiction) of this Agreement to obtain resolution of the dispute.



(4)         If
neither Buyer nor any Seller initiates legal proceedings in respect of the dispute within twelve (12) months following the date
the Dispute Notice is given, the portion of the Indemnity Claim Amount which is disputed will not be an Indemnity Amount Payable,
and the Indemnified Party will have no further right, under this Agreement, to seek to recover such amount from the Indemnifying
Party.



(5)         If
Buyer or Sellers initiates legal proceedings within the twelve (12) month period specified in Section 9.6(b)(ii)(B)(4), the
amount, if any, determined in a Final Order as payable by the Indemnifying Party will be an Indemnity Amount Payable of the relevant
Indemnifying Party as of the date of such Final Order.



- 55 -







Section 9.7           Payments
of Indemnity Amounts Payable by Buyer. Subject to the limitations in Section 9.4, Buyer will pay to each relevant Indemnified
Party any Indemnity Amount Payable by Buyer, by wire transfer of immediately available dollars (or as otherwise directed pursuant
to any Final Order or as otherwise agreed by the Indemnified Party and the Indemnifying Party) to an account designated by Sellers,
promptly and in no event later than ten (10) Business Days after such Indemnity Amount Payable is established in accordance with
this Agreement.



Section 9.8           Payments
of Indemnity Amounts Payable by Sellers. Subject to the limitations in Section 9.4, any Indemnity Amount Payable by Sellers
to each relevant Indemnified Party will be paid by wire transfer of immediately available dollars (or as otherwise directed pursuant
to any Final Order or as otherwise agreed by the Indemnified Party and the Indemnifying Party) to an account designated by Buyer,
promptly and in no event later than ten (10) Business Days after such Indemnity Amount Payable is established in accordance with
this Agreement.



Section 9.9           Exclusive
Remedy. Except for fraud or willful misconduct, the sole and exclusive remedies for any breach of the terms and provisions
of this Agreement (including any representations and warranties and covenants set forth herein, made in connection herewith or
as an inducement to enter into this Agreement) or any claim or cause of action otherwise arising out of or related to the subject
matter hereof, will be such remedies set forth in this Agreement, including and subject to the limitations set forth in this Article 9.

- 57 -







Section 10.2         Entire
Agreement. Except for the Confidentiality Agreement, this Agreement, the TEPC and the Ancillary Agreements supersede
all prior discussions and agreements between the Parties with respect to the subject matter hereof, and this Agreement, the Ancillary
Agreements, the Confidentiality Agreement and the other documents delivered pursuant to this Agreement contain the sole and entire
agreement between the Parties hereto with respect to the subject matter hereof. The Parties hereto have voluntarily agreed to define
their rights, liabilities and obligations with respect to the subject matter hereof exclusively in contract pursuant to the express
terms and provisions of this Agreement, the Ancillary Agreements, the Confidentiality Agreement and the other documents delivered
pursuant to this Agreement; and the Parties hereto expressly disclaim that they are owed any duties or are entitled to any remedies
not expressly set forth in this Agreement. Furthermore, the Parties each hereby acknowledge that this Agreement embodies the justifiable
expectations of sophisticated parties derived from arm’s-length negotiations; all Parties specifically acknowledge that no
Seller has any special relationship with Buyer that would justify any expectation beyond that of an ordinary buyer and an ordinary
seller in an arm’s-length transaction.



Section 10.3         Expenses.
Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated hereby are consummated,
each Party will pay its own costs and expenses incurred in anticipation of, relating to and in connection with the negotiation
and execution of this Agreement and the transactions contemplated hereby, including all expenses and costs incurred to obtain approvals
required by such Party from Governmental Authorities.



Section 10.4         Disclosure.
Sellers may, at their option, include in the Schedules items that are not material in order to avoid any misunderstanding, and
any such inclusion, or any references to dollar amounts, will not be deemed to be an acknowledgment or representation that such
items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this
Agreement. Information disclosed in any Schedule will constitute a disclosure for purposes of all other Schedules notwithstanding
the lack of specific cross-reference thereto, but only to the extent the applicability of such disclosure to such other Schedule
is readily apparent. In no event will the inclusion of any matter in the Schedules be deemed or interpreted to broaden Sellers’
representations, warranties, covenants or agreements contained in this Agreement. The mere inclusion of an item in the Schedules
will not be deemed an admission by Sellers that such item represents a material exception or fact, event, or circumstance or that
such item is reasonably likely to result in a Material Adverse Effect. Each Party will promptly notify the other Party upon becoming
aware of (a) the occurrence, or failure to occur, of any event, which occurrence or failure has caused any representation
or warranty of such Party contained in this Agreement or in any exhibit, schedule, certificate, document or written instrument
attached hereto to be untrue or inaccurate, (b) any failure of such Party to comply with, perform or satisfy, in any respect,
any covenant, condition or agreement to be complied with, performed by or satisfied by it under this Agreement or any exhibit,
schedule, certificate, document or written instrument attached hereto and (c) any notice or other communication from any Governmental
Authority in connection with this Agreement or the transactions contemplated herein and therein; provided, that such disclosure
will not be deemed to cure, or to relieve any Party of any liability or obligation with respect to, any breach of or failure to
satisfy any representation, warranty, covenant or agreement or any condition hereunder, and will not affect any Party’s right
with respect to indemnification hereunder, except as provided in Section 6.8.



- 58 -







Section 10.5         Waiver.
Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no
such waiver will be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such
term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, will be deemed
to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. All remedies
under this Agreement will be cumulative and not alternative.



Section 10.6         Amendment.
This Agreement may be amended, supplemented or modified only by a written instrument duly executed by or on behalf of each Party.



Section 10.7         No
Third Party Beneficiary. Except for the provisions of Sections 9.2 and 9.3 (which are intended for the benefit of the Persons
identified therein), the terms and provisions of this Agreement are intended solely for the benefit of the Parties and their respective
successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other
Person. For the avoidance of doubt, no Person who is not a Party to this Agreement, may challenge any termination of this Agreement,
for any reason, or enforce or seek to enforce any provisions of this Agreement (except as set forth in the first sentence of this
Section).



Section 10.8         Assignment;
Binding Effect. Buyer may assign its rights to indemnification under this Agreement to any Affiliate or to Buyer’s lenders
for collateral security purposes, but such assignment will not release Buyer from its obligations hereunder. Except as provided
in the preceding sentence, neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party
without the prior written consent of each of the other Party.



Section 10.9         Headings.
The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions
hereof.



Section 10.10         Invalid
Provisions. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future
Law, and if the rights or obligations of any Party under this Agreement will not be materially and adversely affected thereby,
such provision will be fully severable, this Agreement will be construed and enforced as if such illegal, invalid or unenforceable
provision had never comprised a part hereof, the remaining provisions of this Agreement will remain in full force and effect and
will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom and in lieu of such illegal,
invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.



- 59 -







Section 10.11         Counterparts;
Facsimile. This Agreement may be executed in any number of counterparts, each of which will be deemed an original, but all
of which together will constitute one and the same instrument. Any facsimile or portable document format (pdf) copies hereof or
signature hereon will, for all purposes, be deemed originals.



Section 10.12         Governing
Law; Venue; and Jurisdiction.



(a)          This
Agreement, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this
Agreement, or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising
out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into
this Agreement), will be governed by the laws of the State of New York without giving effect to any conflict or choice of law provision.



(b)          THE
PARTIES HEREBY IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT IN MINNEAPOLIS, MINNESOTA FOR PURPOSES
OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY AND EACH PARTY HEREBY
CONSENTS TO THE JURISDICTION OF SUCH COURTS (AND OF THE APPROPRIATE APPELLATE COURTS THEREFROM) IN ANY SUCH SUIT, ACTION OR PROCEEDING
AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF
THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT ANY SUCH SUIT, ACTION OR PROCEEDING THAT IS BROUGHT
IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. DURING THE PERIOD A LEGAL DISPUTE THAT IS FILED IN ACCORDANCE WITH
THIS SECTION 10.12 IS PENDING BEFORE A COURT, ALL ACTIONS, SUITS OR PROCEEDINGS WITH RESPECT TO SUCH LEGAL DISPUTE OR ANY
OTHER LEGAL DISPUTE, INCLUDING ANY COUNTERCLAIM, CROSS-CLAIM OR INTERPLEADER, WILL BE SUBJECT TO THE EXCLUSIVE JURISDICTION OF
SUCH COURT. EACH PARTY HEREBY WAIVES, AND WILL NOT ASSERT AS A DEFENSE IN ANY LEGAL DISPUTE, THAT (A) SUCH PARTY IS NOT SUBJECT
THERETO, (B) SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SUCH COURT, (C) SUCH PARTY’S
PROPERTY IS EXEMPT OR IMMUNE FROM EXECUTION, (D) SUCH ACTION, SUIT OR PROCEEDING IS BROUGHT IN AN INCONVENIENT FORUM OR (E) THE
VENUE OF SUCH ACTION, SUIT OR PROCEEDING IS IMPROPER. A FINAL JUDGMENT IN ANY ACTION, SUIT OR PROCEEDING DESCRIBED IN THIS SECTION 10.12
FOLLOWING THE EXPIRATION OF ANY PERIOD PERMITTED FOR APPEAL AND SUBJECT TO ANY STAY DURING APPEAL WILL BE CONCLUSIVE AND MAY BE
ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY APPLICABLE LAWS.



- 60 -







(c)          EACH
PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY.



Section 10.13         Specific
Performance. The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions
of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed
that the Parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement
and to specifically enforce the terms and provisions of this Agreement and any other agreement or instrument executed in connection
herewith or contemplated hereby, and the Parties agree that specific performance is the remedy intended by the parties for any
such breaches or threatened breaches. The Parties further agree that (a) by seeking the remedies provided for in this Section 10.13,
a Party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement,
including monetary damages and (b) the commencement of any Action pursuant to this Section 10.13 or anything contained in
this Section 10.13 shall not restrict or limit any other remedies under this Agreement that may be available then or thereafter.
