amount of this Note and accrued but unpaid interest thereon to be converted by (y) the Conversion Price.

Price or round up to the next whole share.”

V.       Applicable
Law. This Amendment shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect
to its conflict of laws principles.

Purchase and Sale

 

Section 2.01 Purchase and Sale. Upon the
terms and subject to the conditions of this Agreement, at the Closing, Buyer agrees to purchase from Seller, and Seller agrees to sell
to Buyer, free and clear of all Liens (other than Liens imposed by state and federal securities laws), all of Seller’s right and
title to, and interest in, the Interests.

 

Section 2.02 Purchase Price.

 

(a)              
The purchase price for the Interests (the “Purchase Price”) shall equal the sum of (i) the Estimated Closing
Purchase Price, plus (ii) the Adjustment Amount (if applicable). The Purchase Price shall be paid in accordance with Section 2.05
and shall be subject to adjustment as provided in Section 2.06 and Section 7.08.

 

(b)               Within
90 days after the Determination Date, Buyer will submit to Seller a schedule setting forth a proposed allocation of the Purchase
Price (and any other relevant amounts for U.S. federal income tax purposes) (i) among the assets of the Company and any Subsidiary
of the Company that is disregarded as separate from Seller for U.S. federal income tax purposes and (ii) if Buyer timely provides
the Section 338(h)(10) Election Notice pursuant to Section 7.07, among the assets of each Company Group member for which
a Section 338(h)(10) Election will be made, which allocation shall be prepared in accordance with Sections 338 and 1060 of the
Code and the Treasury Regulations issued thereunder (the “Proposed Allocation Schedule”). If, within 30 days
following delivery of the Proposed Allocation Schedule, Seller does not notify Buyer in writing of its disagreement with the
Proposed Allocation Schedule, the Proposed Allocation Schedule shall be final and binding. If Seller submits to Buyer a written
notice of objection to any portion of the Proposed Allocation Schedule within 30 days of Seller’s receipt of the Proposed
Allocation Schedule, then the Parties shall work in good faith for a period of 30 days (or such longer period as they may
mutually agree) of Buyer’s receipt of such objection to resolve any and all disagreements with respect to the Proposed
Allocation Schedule and if they are able to do so shall make such revisions to the Proposed Allocation Schedule to reflect such
resolution, which shall be final and binding. If, within 30 days following Buyer’s receipt of such objection, Seller and Buyer
are unable to resolve such disagreement, the Parties shall request an independent accounting firm to be mutually selected to make a
final determination of any disputed items within 30 days and any such determination by the independent accounting firm shall be
final and binding. The costs of the independent accounting firm shall be borne equally by Seller and Buyer. In the event the Parties
agree on the Proposed Allocation Schedule or revisions of such are deemed accepted and rendered final or resolved by the independent
accounting firm (in each case, the “Final Allocation Schedule”), each Party will not (and will cause its
Affiliates to not) take any position inconsistent with the Final Allocation Schedule on any Tax Return (including IRS Form 8594 and,
if applicable, IRS Form 8883) or in any audit, examination or other proceeding relating to Taxes that is inconsistent with the Final
Allocation Schedule, except to the extent otherwise required by Applicable Law.

or remotely by the exchange of signature pages for executed documents, as promptly as practicable (but no later than two Business Days)

that by their terms are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions) or at such other
time or place as Buyer and Seller may agree in writing; provided, however, that if the Marketing Period has not ended at
the time of the satisfaction or waiver of the conditions set forth in Article 8, the Closing shall occur on the earlier to occur
of (a) a date during the Marketing Period specified by Buyer on no less than three Business Days’ notice to the Seller and (b) the
third Business Day following the end of the Marketing Period (subject in each case to the satisfaction or waiver of all the conditions
set forth in Article 8 for the Closing as of the date determined pursuant to this proviso). The Closing shall be effective as of
the Reference Time.

good faith estimates of (i) Closing Net Working Capital (“Estimated Closing Net Working Capital”), (ii) Closing

Transaction Expenses”) and (iv) Closing Cash (“Estimated Closing Cash”), (b) Seller’s calculation of
the Estimated Net Working Capital Adjustment Amount, and (c) on the basis of the foregoing, a calculation of the Estimated Closing Purchase
Price (together with the calculations referred to in the foregoing clauses above, the “Preliminary Closing Statement”).

 

Section 2.05 Closing Deliverables.

 

(a)              
At or prior to Closing, Seller shall deliver or cause to be delivered to Buyer:

 

(i)                
letters of resignation from the directors and officers of each member of the Company Group set forth on Section 2.05(a)(i)
of the Seller Disclosure Schedule, effective as of the Closing;

 

    22

     

    

 

(ii)             
 copies of the Transaction Agreements, duly executed by Seller and the Company, as applicable;

 

(iii)           
a certification from Seller that Seller is not a “foreign person” within the meaning of Section 1445 of the Code
(it being understood that an IRS Form W-9 shall be acceptable); and

 

(iv)            
the certificate referred to in Section 8.02(c).

 

(b)              
At or before Closing, Buyer shall deliver or cause to be delivered to Seller:

 

(i)                
copies of the Transaction Agreements, duly executed by Buyer;

 

(ii)

the certificate referred to in Section 8.03(c).

 

(c)

by wire transfer to Seller’s Bank Account.

 

Section 2.06 Adjustment Amount.

 

(a)               As
soon as reasonably practicable following the Closing Date, and in any event within 90 calendar days thereof, Buyer shall
prepare and deliver to Seller, Buyer’s calculation of (i) Closing Net Working Capital, (ii) Closing Indebtedness,
(iii) Closing Transaction Expenses, (iv) Closing Cash, (v) Closing Net Working Capital Adjustment Amount, and (vi) on
the basis of the foregoing, a calculation of the Closing Purchase Price (together with the calculations referred to in
clauses (i) through (v) above, the “Final Closing Statement”). The Closing Net Working Capital, Closing
Indebtedness and Closing Cash shall be prepared in accordance with GAAP and the defined terms used in this Section 2.06(a); provided, however,
that the Final Closing Statement (and any amounts included therein) shall not give effect to any act or omission by Buyer or any of
its Subsidiaries or the Company taken after the Reference Time or reflect any payments of cash in respect of the Purchase Price, or
any financing transactions in connection therewith or reflect any expense or liability for which Buyer is responsible under this
Agreement. For the avoidance of doubt, neither Section 2.04 nor this Section 2.06 is intended to be used to adjust the
Closing Purchase Price for errors or omissions, under GAAP or otherwise, that may be found with respect to the Financial Statements
or the Target Net Working Capital. No fact or event, including any market or business development, occurring after the Closing Date,
and no change in GAAP or Applicable Law after the Balance Sheet Date, shall be taken into consideration in the calculations to be
made pursuant to Section 2.04 or this Section 2.06. If Buyer fails to timely deliver the Final Closing Statement in
accordance with the first sentence of this Section 2.06(a) within such 90-day period, then the Preliminary Closing Statement
delivered by Seller to Buyer pursuant to Section 2.04 shall be deemed to be Buyer’s proposed Final Closing Statement,
for all purposes hereunder, and Seller shall retain all of its rights under this Section 2.06 with respect thereto, including
the right to dispute the calculations set forth therein in accordance with the provisions of this Section 2.06.

 

    23

     

    

 

(b)              
Following the Closing, Buyer shall provide Seller and its Representatives access to the records, properties, personnel and (subject
to the execution of customary work paper access letters if requested) auditors of the Company Group relating to the preparation of the
Final Closing Statement and shall cause the personnel of the Company Group to cooperate with Seller in connection with its review of the
Final Closing Statement.

 

(c)               If
Seller shall disagree with any of Buyer’s calculations contained in the Final Closing Statement, it shall notify Buyer of such
disagreement in writing, setting forth in reasonable detail the particulars of such disagreement, within 60 days after its
receipt of the Final Closing Statement. In the event that Seller does not provide such a notice of disagreement within such 60-day
period, Seller shall be deemed to have agreed to the Final Closing Statement (including the determinations included therein)
delivered by Buyer, which shall be final, binding and conclusive for all purposes hereunder. In the event any such notice of
disagreement is timely provided, Buyer and Seller shall work in good faith for a period of 30 days (or such longer period as
they may mutually agree) to resolve any disagreements with respect to any calculations contained in the Final Closing Statement. If,
at the end of such period, they are unable to resolve such disagreements, then any such remaining disagreements (such remaining
disagreements, the “Disputed Items”) shall be resolved by KPMG LLP, or if KPMG LLP is unavailable for such
engagement or at the time of such proposed engagement is no longer independent, such other independent accounting firm of
internationally recognized standing as may be mutually selected by Buyer and Seller (such firm, the “Auditor”).
Buyer and Seller shall promptly provide their assertions regarding the Disputed Items in writing to the Auditor and to each other.
The Auditor shall be instructed to render its determination with respect to the Disputed Items as soon as reasonably possible (which
the Parties agree should not be later than 45 days following the date on which the disagreement is referred to the Auditor).
The Auditor shall base its determination solely on (i) the written submissions of the Parties and shall not conduct an
independent investigation and (ii) the extent (if any) to which Closing Net Working Capital, Closing Indebtedness, Closing
Transaction Expenses and/or Closing Cash require adjustment (only with respect to the Disputed Items submitted to the Auditor) in
order to be determined in accordance with Section 2.06(a) (including the definitions of the defined terms used in Section
2.06(a)). The Auditor shall not assign a value to any Disputed Item submitted to the Auditor greater than the greatest value for
such item claimed by either Party or less than the smallest value for such item claimed by either Party. The determination of the
Auditor shall be final, conclusive and binding on the Parties. The date on which Closing Net Working Capital, Closing Indebtedness,
Closing Transaction Expenses, Closing Cash, Closing Net Working Capital Adjustment Amount and Closing Purchase Price are finally
determined in accordance with this Section 2.06(c) is hereinafter referred to as the “Determination Date.”
All fees and expenses of the Auditor relating to the work, if any, to be performed by the Auditor hereunder shall be borne between
Buyer and Seller, based upon a fraction, the numerator of which is the portion of the aggregate amount of the Disputed Items not
awarded to the applicable Party and the denominator of which is the aggregate amount of the Disputed Items. (For example, if Seller
challenges items underlying the calculations of Closing Net Working Capital, Closing Indebtedness and/or Closing Cash in the net
amount of $1,000,000, and the Auditor determines that Seller has a valid claim for $400,000 of the $1,000,000, Seller shall bear 60%
of the fees and expenses of the Auditor and Buyer shall bear 40% of the fees and expenses of the Auditor.)

 

    24

     

    

 

(d)              
The “Adjustment Amount,” which may be positive or negative, shall mean the Closing Purchase Price (as finally
determined in accordance with Section 2.06(a) or Section 2.06(c), as applicable) minus the Estimated Closing Purchase Price.
The Adjustment Amount shall be paid in accordance with Section 2.06(e).

 

(e)              
If the Adjustment Amount is a positive number (such amount, the “Increase Amount”), then, promptly following
the Determination Date, and in any event within three Business Days of the Determination Date, Buyer shall pay to Seller an amount equal
to the Increase Amount in immediately available funds by wire transfer to Seller’s Bank Account. If the Adjustment Amount is a negative
number (the absolute value of such amount, the “Deficit Amount”), then, promptly following the Determination Date,
and in any event within three Business Days of the Determination Date, Seller shall pay to Buyer an amount equal to the Deficit Amount
in immediately available funds by wire transfer to an account of Buyer designated by Buyer. The Parties agree that any payment made pursuant
to this Section 2.06(e) shall be treated as an adjustment to the Purchase Price for U.S. federal income (and other applicable)
tax purposes, except to the extent otherwise required by Applicable Law.

 

Section 2.07 Withholding. Notwithstanding
anything to the contrary contained in the Transaction Agreements, Buyer, its Affiliates and, effective upon the Closing, each Company
Group member, and any of their respective agents, shall be entitled to deduct and withhold from any amount otherwise payable pursuant
to the Transaction Agreements such amounts as are required to be deducted and withheld with respect to the making of such payment under
Applicable Law; provided, however, that if a Person intends to make any deduction or withholding from any such payment it
shall inform the other Person at least five days in advance of the relevant payment of its intention to make such deduction or withholding
(or as soon as practicable if later, in the case of (a) an obligation to deduct or withhold as a result of a change in Law within such
five day period or (b) any payment due within five days of Buyer becoming aware of its obligation to make such payment), including the
amount to be deducted and withheld and the basis for such deduction and withholding, and reasonably cooperates with the other Person to
reduce or eliminate such deduction or withholding. In the event that any amounts are so withheld, Buyer shall (a) timely remit, or cause
to be remitted, such amounts to the applicable Governmental Authority in accordance with Applicable Law and (b) cooperate with Seller
as and to the extent reasonably requested in connection with filing and pursuing any claim for a refund of such Taxes. If any amount is
so withheld and paid over to the applicable Governmental Authority or other appropriate Person, such withheld amounts shall be treated
for all purposes of the Transaction Agreements as having been paid to the Person with respect to which such deduction or withholding was
imposed. Assuming that Seller provides the closing deliverable described in Section 2.05(a)(iii), each of Buyer and Seller hereby
agrees that it is not aware of any Applicable Law in effect as of the date hereof that would require Buyer or any of its Affiliates to
deduct and withhold from any amounts payable to any Person pursuant to this Agreement.

Section 3.18(a) of the Seller Disclosure Schedule sets forth a complete list as of the date hereof of each material Employee
Benefit Plan and separately identifies each Company Benefit Plan. For each material Employee Benefit Plan, Seller has made available to
Buyer, as applicable (i) the current plan document, adoption agreement, trust agreement, insurance Contracts and all amendments thereto
(and, in the case of an unwritten plan, a summary of the material terms thereof), (ii) the most recent determination or opinion letter
from the IRS, (iii) the current summary plan description and summaries of material modifications, (iv) the three most recently
filed annual reports, and (v) actuarial valuation reports for the three most recent plan years.

Except as set forth on Section 3.18(b) of the Seller Disclosure Schedule, (i) no Employee Benefit Plan is, and neither the
Company nor any member of the Controlled Group currently has any liability with respect to, or any obligation to contribute to, (A) a
 “defined benefit plan” as defined in Section 3(35) of ERISA, (B) a pension plan subject to Title IV of ERISA or the funding
standards of Section 302 of ERISA or Section 412 of the Code or (C) a Multiemployer Plan; and (ii) no Company Benefit Plan provides
benefits to any Person who is not a current or former employee of a member of the Company Group or the beneficiary thereof.

 

(c)       
Each Employee Benefit Plan that is intended to be qualified under Section 401(a) of the Code has received a currently effective
favorable determination or opinion letter from the IRS and, to Seller’s Knowledge, nothing has occurred that would reasonably be
expected to result in loss of such qualification.

 

(d)       
Each Employee Benefit Plan has been maintained, operated, and administered in material compliance with its terms and any related
documents or agreements and in material compliance with all Applicable Laws. There have been no prohibited transactions or breaches of
any of the duties imposed on “fiduciaries” (within the meaning of Section 3(21) of ERISA) by ERISA with respect to the
Employee Benefit Plans that would reasonably be expected to result in any material liability or excise tax under ERISA or the Code being
imposed on any member of the Company Group. No member of the Company Group has any liability (including on account of a member of the
Controlled Group) for any Tax under Chapter 43 of the Code or Part 6 of Subtitle B of Title I of ERISA.

 

(e)       
Except as set forth on Section 3.18(e) of the Seller Disclosure Schedule, there is no pending nor, to the Knowledge of Seller,

individual” (as such term is defined in Treasury Regulation Section 1.280G-1) under any employment, severance or termination
agreement or other compensation arrangement of the Seller, the Company or any Employee Benefit Plan currently in effect would be characterized
as an “excess parachute payment” (as such term is defined in Section 280G(b)(1) of the Code).

 

(g)      
Except as set forth on Section 3.18(g) of the Seller Disclosure Schedule, neither the execution and delivery of this Agreement,
nor the consummation of the transactions contemplated herein (either alone or upon the occurrence of any additional or subsequent event),
will cause any (i) payments to become due or payable to any Company Employee or other Company service provider, or (ii) payment,
acceleration, vesting or increase in benefits to any Company Employee or other Company service provider.

 

(h)       
Except as set forth on Section 3.18(h)(i) of the Seller Disclosure Schedule, no Company Benefit Plan provides medical or
other health or life insurance benefits to any Company Employee following such individual’s retirement or other termination of employment
or service, except as required by Section 4980B of the Code or other Applicable Law. Except as set forth on Section 3.18(h)(ii)
of the Seller Disclosure Schedule, no Employee Benefit Plan provides medical or other health or life insurance benefits to any individual
following such individual’s retirement or other termination of employment or service, except as required by Section 4980B of the
Code or other Applicable Law.

 

(i)        
With respect to Company Employees, each Employee Benefit Plan that is subject to Section 409A of the Code complies, by its terms
and in operation, in all material respects with Section 409A of the Code. None of Seller or any of its Subsidiaries (including the Company

Buyer has delivered to Seller a Debt Commitment Letter, pursuant to which the Debt Financing Sources have committed to provide
debt financing for the transactions contemplated by this Agreement in the aggregate amount set forth therein. Buyer has also delivered
to Seller a true, correct and complete (other than the redaction noted below) copy of the fee letter (as amended, supplemented, replaced,

Debt Commitment Letter or the Fee Letter not being satisfied, (iii) cause the Fee Letter or the Debt Commitment Letter to be

with its advisors) has sufficient knowledge and experience in financial and business matters so as to be capable of evaluating the merits
and risks of its investment in the Interests and is capable of bearing the economic risks of such investment.

with the transactions contemplated by this Agreement with the intent to hinder, delay or defraud either present or future creditors of
Buyer.

businesses such as its acquisition of the Interests as contemplated hereunder. Buyer has undertaken such investigation and has been provided
with and has evaluated such documents and information as it has deemed necessary to enable it to make an informed and intelligent decision
with respect to the execution, delivery and performance of this Agreement. Buyer acknowledges that Seller has given Buyer complete and
open access to the employees and facilities of the Company Group and acknowledges that it has been provided to access to the documents

further investigation and request such additional documents and information as it deems necessary. Buyer agrees to accept the Interests
and the Company Group members in the condition they are in on the Closing Date based upon its own inspection, examination and determination
with respect thereto as to all matters and hereby disclaims reliance upon any express or implied representations or warranties of any
nature made by Seller or any Company Group members or any of their respective Representatives, except for those specifically and expressly
set forth in Article 3. Buyer specifically acknowledges and agrees to Seller’s and the Company Group members’ express
disavowal and disclaimer of any other representations or warranties, whether made by Seller, the Company Group members or any of their

any opinion, information, projection, or advice that may have been or may be provided to Buyer, its Affiliates or Representatives by any
Representative or Affiliate of Seller). Accordingly, Buyer acknowledges and agrees that, without limiting the generality of this Section
4.10, neither Seller nor the Company Group members has made any representation or warranty with respect to any projections or other
forecasts and plans. Buyer specifically acknowledges and agrees that except for the representations and warranties contained in Article
3 (as modified by the Seller Disclosure Schedule), none of Seller, the Company Group members or any other Person makes, or has made,
any other express or implied representation or warranty with respect to the Company Group members or the transactions contemplated by
this Agreement.

or area of the term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision
with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision, and this Agreement will be enforceable as so modified after the expiration of the time within which
the judgment may be appealed.

    56

     

    

 

(b)              
Buyer shall keep Seller apprised of all material developments relating to the Debt Financing. Buyer shall promptly (and in any
event within two Business Days) notify Seller of (i) the expiration or termination of the Debt Commitment Letter, (ii) any refusal by
the Debt Financing Sources to provide, or any stated intent by the Debt Financing Sources to refuse to provide, the full Debt Financing
contemplated by the Debt Commitment Letter, (iii) any breach or default (or any change, circumstance, fact occurrence or event that, with
or without notice, lapse of time or both, would reasonably be expected to give rise to any breach or default) by Buyer or, to the knowledge
of the Buyer, any other party to the Debt Commitment Letter or definitive document that may cause Buyer to no longer be able to obtain
all or any portion of the Debt Financing contemplated by the Debt Commitment Letter on the terms described therein (and that Buyer will
not be able to obtain acceptable Alternative Financing), (iv) any change, circumstance, fact occurrence or event of which Buyer becomes
aware that, with or without notice, lapse of time or both, would reasonably be expected to cause Buyer to no longer be able to obtain
all or any portion of the Debt Financing contemplated by the Debt Commitment Letter on the terms described therein (and that Buyer will
not be able to obtain acceptable Alternative Financing), or (v) receipt of any written notice or other written communication from any
Person with respect to any (A) actual or potential breach, default, termination or repudiation by any party to the Debt Commitment Letter
or any definitive document related to the Debt Financing or (B) material dispute or disagreement between or among any parties to the Debt
Commitment Letter or any definitive document that would cause Buyer to no longer be able to obtain all or any portion of the Debt Financing
contemplated by the Debt Commitment Letter on the terms described therein (and that Buyer will not be able to obtain acceptable Alternative
Financing).

 

(c)               Buyer
shall not replace, amend or waive the Debt Commitment Letter or the Fee Letter without Seller’s prior written consent if such
replacement, amendment or waiver (i) reduces the aggregate amount of the Debt Financing (including by changing the amount of fees to
be paid or original issue discount thereof) unless Buyer delivers to Seller evidence in form and substance reasonably acceptable to
Seller that Buyer shall otherwise have available cash sufficient to consummate the Closing, (ii) imposes new or additional
conditions, or otherwise expands any of the conditions, to the receipt of Debt Financing or (iii) effects any other amendment,
modification or waiver that would reasonably be expected to prevent or materially delay or impede the consummation of the
transactions contemplated by this Agreement. Buyer shall provide to Seller copies of any commitment letter associated with a
replacement Debt Financing or Alternative Financing as well as any amendment or waiver of any debt commitment letter (including the
Debt Commitment Letter) that is permitted hereunder.

 

    57

     

    

 

(d)               From
the date hereof until the Closing Date, Seller shall, and shall cause the Company Group members (and its and their respective
Representatives) to, at Buyer’s sole cost and expense, provide such cooperation reasonably requested by Buyer or any of its
Affiliates or Representatives in connection with the arrangement of Debt Financing as required by the terms of the Debt Commitment
Letter, including Commercially Reasonable Efforts to: (i) furnish Buyer with documentation and other information of Seller and the
Company Group members as required under applicable “know your customer” and anti-money laundering rules and regulations,
including the Patriot Act, in each case, that has been reasonably requested in writing by Buyer not less than 5 Business Days prior
to the Closing Date, (ii) facilitating instruments of discharge with respect to the Indebtedness of the Company Group required to be
released prior to the Closing Date in order to transfer the Interests to Buyer free and clear of all Liens (other than Liens imposed
by state and federal securities laws), pursuant to Section 2.01 on the Closing Date, (iii) facilitating the pledging of
collateral to the extent required by the terms of the Debt Commitment Letter and reasonably requested by Buyer (in each case,
subject to and only effective upon the occurrence of the Closing) and assist with the production of factual information required in
connection with the preparation of any credit agreement, pledge and security documents, perfection certificates, mortgages, deeds of
trust, hedging agreements, legal opinions reasonably requested (including on behalf of the Debt Financing Sources), legal opinion
support certificates or other definitive financing documents or other documents related to the Debt Financing (including schedules,
insurance certificates, and evidence of corporate authority) as may be reasonably requested by the Buyer, (iv) participation by
senior management of the Seller and the Company Group in, and assistance with, (1) the preparation of rating agency presentations,
(2) meetings with rating agencies, roadshows, due diligence sessions, drafting sessions and meetings with prospective lenders and
debt investors and (3) the preparation of confidential information memoranda, investor presentations, lender presentations, roadshow
presentations and similar customary documents as may be reasonably requested by Buyer or any Lender, in each case, with respect to
information relating to the Seller and the Company Group in connection with customary marketing efforts of Buyer for all or any
portion of the Debt Financing (collectively, the “Marketing Material”), (v) provide reasonable and customary

cause the Company’s auditors to deliver customary consents and comfort letters (including “negative assurance” and

use of their reports in any materials or disclosures relating to the Debt Financing, (vii) provide reasonably requested information
relating to the compliance by the Seller and the Company Group with all applicable government laws and regulations, (viii) furnish
Buyer with the financial statements and other information described in Section 5.14 and (ix) allow the usual and customary

in a manner that is not intended or reasonably likely to harm, disparage or otherwise adversely affect the Seller’s or any
Company Group member’s reputation or goodwill), subject to Seller’s prior approval of such materials; provided, however,
that nothing herein shall require Seller, the Company Group members or any of their respective Representatives or Affiliates to take
any action that would be effective prior to the Closing Date or to the extent it would, in Seller’s reasonable judgment,
interfere unreasonably with the business or operations of Seller or its Affiliates (including the Company Group members).

 

    58

     

    

 

(e)              
Neither Seller nor any of its Affiliates (including the Company Group members) shall be required to pay any commitment or other
similar fee or make any other payment or incur any other liability or provide or agree to provide any indemnity in connection with the
Debt Financing or any of the foregoing that would be effective prior to the Closing Date or would be treated as a Company Transaction
Expense. None of Seller, its Affiliates or their respective Representatives shall be required to (i) execute or enter into or perform
any Contract contemplated by the Debt Commitment Letter that is not contingent upon the Closing Date or that would be effective prior
to the Closing Date (other than as contemplated under Section 5.12(d)), (ii) adopt resolutions approving the agreements, documents
and instruments pursuant to which the Debt Financing is obtained or take any corporate actions prior to the Closing Date to permit the
consummation of the Debt Financing, (iii) provide in connection with the Debt Financing any information the disclosure of which is prohibited

or any of their respective Representatives incurring any liability with respect to the matters relating to the Debt Financing or cause
any director, officer or employee of Seller, its Affiliates or their respective Representatives to incur any personal liability in connection
with the Debt Financing, or (v) other than with respect to current or historical financial information required to be furnished pursuant
to Section 5.12(d), provide (A) pro forma financial information, including pro forma cost savings, synergies, capitalization or
other pro forma adjustments desired to be incorporated into any pro forma financial information, (B) any description of all or any component
of the Debt Financing (including any such description to be included in any liquidity or capital resources disclosure or any “description
of notes”), (C) projections, risk factors or other forward-looking statements relating to all or any component of the Debt Financing,
or (D) any solvency certificate or similar certification or representation (which items (A) through (D) shall be the sole responsibility
of Buyer). None of Seller, the Company Group members, or any of their respective Representatives or Affiliates shall be required to make
any representation, warranties or certifications in connection with the Debt Financing as to which, after the use of Commercially Reasonable
Efforts to cause such representation, warranty or certification to be true, such Person has in its good faith determined that such representation,
warranty or certification is not true. Seller shall be given a reasonable opportunity to review and comment on any financing documents
and review any materials that are to be presented during any meetings conducted in connection with the Debt Financing, and Buyer shall
give due consideration to all reasonable additions, deletions or changes suggested thereto by Seller.

 

    59

     

    

 

(f)               
 Buyer acknowledges and agrees that Seller will not, except as set forth in this Agreement, have any liability to any Person under
or in connection with, the arrangement of the Debt Financing that Buyer may raise in connection with the transactions contemplated by
this Agreement. Buyer shall promptly, upon request by Seller (including following a valid termination of this Agreement in accordance
with Article 10), reimburse Seller for all reasonable and documented out-of-pocket costs and expenses (including reasonable and
documented out-of-pocket attorneys’ fees) incurred by Seller and the Company Group members in connection with the cooperation of
Seller and its Affiliates contemplated by this Section 5.12 and shall indemnify and hold harmless Seller, the Company Group members,
and their respective Representatives from and against any and all Damages suffered or incurred by any of them of any type in connection
with the arrangement of the Debt Financing, except to the extent such Damages arise from or in connection with gross negligence or Fraud
by Seller, the Company Group members of their respective Representatives.

 

(g)              
Notwithstanding anything to the contrary in this Agreement, the condition set forth in Section 8.02(b), as it applies to
Seller’s obligations under this Section 5.12, shall be deemed satisfied unless Seller willfully fails to perform its obligations
under this Section 5.12 and such willful failure to perform has been the primary cause of the Debt Financing not being obtained.

 

Section 5.13 Return of Assets; Post-Closing
Railroad Asset Transfers.

 

(a)              
If, at any time after the Closing, it is reasonably determined by the Parties that any personal property (other than Railroad Assets)
held by a Party or any of its respective Affiliates (including, in the case of Buyer, the Company Group members) should have been delivered
or conveyed to the other Party’s possession at or prior to the Closing due to the fact that (i) such personal property was included
in the scope of the Business, in the case of such personal property held by Seller or its Affiliates or (ii) such personal property is
not included in the scope of the Business, in the case of such personal property held by Buyer or its Affiliates (including the Company
Group after the Closing), then (a) such Party shall return or transfer and convey such property (without further consideration or for
nominal consideration, if required by Applicable Law) to such other Party or its applicable Affiliate and (b) Seller and Buyer shall,
and shall cause their applicable Affiliates to, execute such documents or instruments of conveyance or assumption and take such further
acts as are reasonably necessary or desirable to effect the transfer back of such asset, in each case such that each Party is put into
the same economic position as if such action had been taken on or prior to the Closing Date.

 

(b)               Without
limiting the generality of Section 5.13(a), from and after the Closing, to the extent requested in writing by Buyer, the
Parties shall, and shall cause their respective Affiliates to, use their respective Commercially Reasonable Efforts to undertake
such subdivisions, transfers and conveyances as are reasonably practicable in order to realign the ownership of Railroad Assets such
that the applicable Company Group member will own all such Railroad Assets previously owned by Sellers and its Affiliates (other
than Company Group members) sited outside of the fence line of the applicable facilities served by the applicable Company Group
member (set forth on the diagrams attached to Section 1.01(a) of the Seller Disclosure Schedule); provided, that as
used in this Section 5.13, “Railroad Assets” shall exclude all locomotives and rail cars. Any transfers or
conveyances consummated pursuant to this Section 5.13(b) shall (x) include the assumption by the Company Group of all known
and unknown historical obligations and liabilities relating to the underlying Railroad Assets, (y) include representations or
warranties of the transferor solely as to title and authority to enter into the transaction contemplated thereby and (z) otherwise
be on an “as-is, where-is” basis. All costs and expenses arising from the transfers and other actions contemplated by
this Section 5.13(b), including any Transfer Taxes imposed in connection therewith, costs of surveys, title work and
attorneys and other advisors’ fees, shall be borne by Buyer and Buyer shall reimburse Seller for all reasonable and documented
out-of-pocket costs and expenses (including reasonable and documented out-of-pocket advisors’ fees) incurred by Seller or any
of its Affiliates in connection the foregoing.

 

    60

     

    

 

Section 5.14 Financial Statement Assistance.
As soon as reasonably practicable after the end of each calendar quarter ending prior to the Closing Date (commencing with the calendar
quarter ending June 30, 2021), Seller shall deliver to Buyer an unaudited consolidated balance sheet for the Company Group as of the last
day of such calendar quarter and the related unaudited statements of income, equity and cash flows for the three-month period then ended
and for the same period in the comparative prior year. Each of the financial statements delivered by Seller pursuant to this Section
5.14 shall be prepared in accordance with GAAP applied on a consistent basis (subject to the absence of footnote disclosures or year-end
audit adjustments). In addition to the foregoing, from and after the date hereof until the first anniversary of the Closing Date, Seller
shall, and shall cause its Affiliates (including, prior to Closing, the Company Group) to, provide Buyer and its Affiliates with reasonable
assistance and good faith cooperation and copies of all existing financial and other records related to the Company Group to the extent
reasonably requested by Buyer or any of its Affiliates to prepare (or have prepared) filings and financial statements and the notes thereto
for the calendar years ended December 31, 2020 and 2019 and each calendar quarter ending after the date hereof up to and including the
first calendar quarter ending immediately following the Closing Date, in each case, meeting the requirements of Regulation S-X promulgated
by the Securities and Exchange Commission. For the avoidance of doubt, preparation of audited financial statements shall not be a condition
to Closing.

 

Section 5.15 Redemption of USS Portfolio Shares.
Prior to the Closing Date, but no later than the Business Day immediately prior to the Closing Date, (a) Seller shall cause USS Portfolio
to redeem all shares of Class A, Series I Preferred Stock of USS Portfolio held by each Company Group member in exchange for cash and
take all such other actions necessary to terminate the relationship between USS Portfolio and the Company Group, including to terminate
all related investment letter agreements by and between USS Portfolio and any Company Group member and (b) immediately following such
redemptions, Seller shall cause each of the Company Group members to declare and pay a special cash distribution or dividend, as applicable,
to distribute excess cash-on-hand (in amounts to be determined by Seller) to Seller.

 

Section 5.16 Guarantees; Letters of Credit.

 

(a)               Without
limiting Section 5.16(b) in any respect, Buyer shall use Commercially Reasonable Efforts to cause itself or the Company Group
members to be substituted in all respects for Seller and any of its Affiliates and for Seller and its Affiliates to be released,
effective as of the Closing, in respect of all liabilities and obligations of Seller and any of its Affiliates under or related to
each of the Seller Guarantees (including by posting letters of credit or cash collateralizing such liabilities and obligations), and
Seller shall reasonably cooperate with Buyer’s efforts. For any Seller Guarantee for which Buyer or any Company Group member,
as applicable, is not substituted in all respects for Seller and its Affiliates (or for which Seller and its Affiliate are not
released), effective as of the Closing, Buyer shall continue to use its Commercially Reasonable Efforts, and shall cause the Company
Group members to use their Commercially Reasonable Efforts, to effect such substitution and release after the Closing, and Seller
shall continue to reasonably cooperate in Buyer’s efforts; provided that Seller and its Affiliates shall not have any
obligation to make payments or incur any costs or expenses, grant any concession or incur any other Liability in connection with
such cooperation pursuant to this Section 5.16(a) except to the extent Buyer agrees to promptly reimburse Seller and its
Affiliates or agrees to fully indemnify Seller and its Affiliates for any such liabilities to Seller’s satisfaction. The
Parties agree that neither Seller nor any of its Affiliates after the Closing will have any obligation to renew any Seller Guarantee
after the expiration thereof.

 

    61

     

    

 

(b)              
Without limiting Section 5.16(a) in any respect, from and after the Closing, Buyer and the Company Group members, jointly
and severally, shall indemnify and hold harmless the Seller Indemnified Parties against any liabilities that Seller or any of its Affiliates
suffer, incur or are liable for by reason of or arising out of or in consequence of (i)  Seller or any of its Affiliates issuing,
making payment under, being required to pay or reimburse the issuer of or any other Person in connection with, or being a party to, any
Seller Guarantee, (ii) any claim or demand for payment made on Seller or any of its Affiliates with respect to any Seller Guarantee
or (iii) any claim or Legal Proceeding by any Person who is or claims to be entitled to the benefit of or claims to be entitled to
payment, reimbursement or indemnity with respect to any Seller Guarantee.

Seller shall cooperate to obtain the consent of the United States Federal Communications Commission (“FCC”) pursuant
to 47 U.S.C. § 310(d) and 47 C.F.R. § 1.948 for the transfer of control of the radio license authorizations set forth on Section
5.17 of the Seller Disclosure Schedule (“FCC Licenses”). Promptly following execution of this Agreement, but not
later than five Business Days following execution of this Agreement, Seller shall initiate the electronic filing of a FCC Form 603, “FCC
Application for Assignments of Authorization or Transfers of Control,” through the FCC’s Universal Licensing System, for each
FCC License and shall be responsible for the filing fees associated with such applications. Buyer shall electronically approve and sign
the FCC Form 603 applications through the Universal Licensing System and shall, within 30 days after the Closing Date, notify the FCC
of the consummation of the transfer of control of each FCC License through the filing of FCC Form 603, Schedule D.

 

    62

     

    

 

Section 5.18 Shared
Contracts. Except as otherwise agreed by Seller and Buyer or as otherwise provided in this Agreement or any other Transaction
Agreement (including with respect to any Shared Contracts that relate to services to be provided under the Transition Services
Agreement), until the earlier of 12 months following the Closing Date and the expiration or termination date of the applicable
Shared Contract (assuming, for these purposes, that the then-current term in effect as of immediately prior to the Closing is not
renewed or extended), the Parties shall (and shall cause their respective Affiliates to) use Commercially Reasonable Efforts to, at
no cost to Seller or its Affiliates, obtain or structure an arrangement for Buyer or its applicable Affiliates to receive the rights
and benefits, and bear the obligations and burdens, of such portion of any such Shared Contract that relates to the Business and is
allocated to the Company Group in accordance with this Section 5.18. Each such arrangement shall provide Buyer with the
ability to direct Seller or its applicable Affiliate to undertake any action or not undertake any action with respect to the
underlying Shared Contract solely as it relates to the Business; provided that Seller and its Affiliates shall not be
required to take any action or not take any action that would constitute a breach or other contravention of the rights of any other
Person, or be ineffective under or contravene Applicable Law or the applicable Shared Contract or materially and adversely affect
the contractual rights of Seller or its Affiliates under such Shared Contract. Buyer shall indemnify and hold harmless Seller and
its Affiliates from any and all Damages or other Liabilities arising out of each such arrangement (other than Shared Contractual
Liabilities (x) allocated to Seller in accordance with this Section 5.18 or (y) arising out of Seller’s breach of this Section
5.18). Seller shall indemnify and hold harmless Buyer and its Affiliates from any and all Damages or other Liabilities arising
out of (x) any breach of any Shared Contract by Seller or its Affiliates or (y) the gross negligence or willful misconduct of Seller
or its Affiliates in connection with Seller’s or its Affiliates’ administration of any such arrangement or any Shared
Contract. With respect to Shared Contractual Liabilities pursuant to, under or relating to any Shared Contract, such Shared
Contractual Liabilities shall be allocated between Seller and Buyer as follows: (a) if a Liability is incurred solely in respect of
the Business or the remainder of Seller’s business (other than the Business), such Liability shall be allocated to Buyer (in
respect of the Business) or Seller (in respect of the reminder of Seller’s business (other than the Business)); and (b) if a
Liability cannot be so allocated under clause (a), such Liability shall be allocated to Seller or Buyer, as the case may be,
based on the relative proportion of total benefit received by the Business and the reminder of Seller’s business (other than
the Business) under the relevant Shared Contract.

 

Section 5.19 Further Assurances. From and
after the Closing, each of Buyer, Seller and the Company shall use Commercially Reasonable Efforts from time to time to execute and deliver
at the reasonable request of the other Party such additional documents and instruments, and to take, or refrain from taking, such other
actions, as may be reasonably required to give effect to this Agreement and the transactions contemplated hereby.

the foregoing quitclaim deed, Seller and GRW shall amend and restate that certain Lease, dated February 1, 2013, by and between
Seller and GRW, to reflect GRW’s ownership of the Gary Locomotive Shop and to incorporate customary arms-length terms for a
commercial lease of similar nature (including separate metering of utilities and fair market rent), in each case in form and
substance reasonably acceptable to Buyer, which amended and restated lease shall become effective upon the Closing. After the
Closing, Buyer and Seller shall take, or cause one or more of their respective Affiliates (including GRW) to take, any and all
actions, and execute and deliver any deeds, subdivision plats, certificates, filings, agreements or other instruments, in each case,
that are reasonably necessary to convey, transfer and assign the approximately three acres of land on which the Gary Locomotive Shop
is situated as depicted on Section 5.20(b)(ii) of the Seller Disclosure Schedule, together with railroad tracks and other
railroad-related equipment situated thereon (commonly referred to as the Repairs in Progress facility), from Seller to GRW as soon

(ii) licenses providing the applicable Company Group member with perpetual access to and use of real estate, tracks and other rail facility
appurtenances thereto owned, licensed or leased by Seller or its Affiliates outside of Seller’s plants in the manner in which such
access and use is provided to such Company Group member as of the date hereof, which licenses will not require the payment of any fee
or other amount by such Company Group Member and shall be in a recordable form (collectively, the “License Agreements”),
in each case, in form and substance reasonably acceptable to Seller and Buyer.

 

(d)              
Notwithstanding anything to the contrary in the foregoing, each Party agrees to negotiate in good faith the deeds, leases, licenses,
agreements, certificates and instruments contemplated by this Section 5.20 and to reasonably cooperate with the other Party in
connection with the consummation of the transactions contemplated by this Section 5.20.

 

Section 5.21 Existing
Asbestos Litigation and US Smelter Existing Claims. Notwithstanding anything in this Agreement to the contrary, from and after
the Closing, Seller shall, at Seller’s sole cost and expense, control in all respects any Legal Proceeding listed on Section
5.21 of the Seller Disclosure Schedule (“Existing Asbestos Litigation”) and the US Smelter Existing Claims,
including the settlement, compromise, prosecution or defense thereof, as applicable; provided, however, that Seller
shall not: (i) settle or compromise any Existing Asbestos Litigation or US Smelter Existing Claims or consent to the entry of any
Order with respect thereto which does not include an unconditional, duly authorized, fully executed and acknowledged (by a duly
registered notary public) written release of the applicable member of the Company Group from all liability in respect of such
Existing Asbestos Litigation or US Smelter Existing Claims; (ii) settle or compromise any Existing Asbestos Litigation or US Smelter
Existing Claims if the settlement imposes equitable remedies or other obligations on the Company Group; (iii) settle or compromise
any Existing Asbestos Litigation or US Smelter Existing Claims if the result is to admit civil or criminal liability on the part of
the Company Group; or (iv) take any action in such capacity pursuant to this Section 5.21 that would reasonably be likely to
adversely affect the business or operations of the Company Group in any material respect, in each case, without first obtaining the
prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed. Seller shall direct legal
counsel selected by Seller pursuant to this Section 5.21 to submit all bills and invoices directly to Seller and, with regard
to the US Smelter Existing Claims, shall direct Wisconsin Central Ltd., and its Affiliates as applicable, to submit any invoices or
other requests for payment directly to Seller. Seller may choose, at its sole option, to relinquish its right to prosecute any
Existing Asbestos Litigation or US Smelter Existing Claims pursuant to this Section 5.21 if requested by Buyer or the
Company, and if so elected, shall use Commercially Reasonable Efforts to permit Buyer or the Company, as applicable, to exert sole
and exclusive control over such Existing Asbestos Litigation or US Smelter Existing Claims; provided, however, that
the costs incurred by Buyer or its Affiliates to defend such Existing Asbestos Litigation or US Smelter Existing Claims shall be
Damages for which indemnification is provided under Section 9.02(a)(iv).

respective Affiliates and Representatives to, reasonably cooperate with the other Party in the defense or prosecution of any Legal
Proceeding that has been or may be instituted hereafter against such other Party or its Subsidiaries or Affiliates relating to or
arising out of the conduct of the Business prior to the Closing (other than Legal Proceedings (x) between a Party or its
Subsidiaries or Affiliates and the other Party or its Subsidiaries or Affiliates or (y) in which a Party or its Subsidiaries or

Legal Proceeding as reasonably requested a Party; (c) making employees (and, to the extent reasonably feasible, former employees)
reasonably available (i) to provide information concerning such Legal Proceeding or the underlying subject matter of such Legal
Proceeding, (ii) for the preparation of any work in connection with such Legal Proceeding or (iii) to testify at a deposition, trial
or other proceeding concerning such Legal Proceeding; and (d) providing access to materials, documents, emails and data residing

that, in no event shall (x) the access to any employees provided pursuant to this Section 5.22 unreasonably interfere with
the duties of such employees or (y) either Party or its respective Subsidiaries or Affiliates be required to provide access to any
materials, documents, emails or data if doing so would violate Applicable Law or may compromise the attorney-client privilege of
such materials, documents, emails and data. The Party requesting cooperation pursuant to this Section 5.22 shall pay the
reasonable expenses (including reasonable attorneys’ fees and expenses) of such cooperating Person incurred as a result of
providing such cooperation.

or assignee of all or any part of the Company Group members or their respective businesses) to, (i) maintain the Company Books and Records
for a period of six years (subject to the earlier disposal procedures in this Section 5.23(c)); (ii) for such six year period,
upon reasonable written notice and during Working Hours, afford to Seller and its agents reasonable access to (A) properties, copies of
Company Books and Records for the period prior to Closing and (B) employees and auditors of the Company Group, in each case to the extent
necessary to permit Seller to perform or satisfy any legal, accounting, Tax or regulatory obligation relating to any period on, before
or that includes the Closing Date. Notwithstanding the foregoing, Buyer shall not be required to provide access or disclose information
to the extent that such access or disclosure would jeopardize the attorney-client privilege or contravene any Applicable Law. Notwithstanding
such six-year period, Buyer or its Affiliates shall be entitled to dispose of any original of the Company Books and Records, provided,
that before Buyer or its Affiliates shall dispose of any such originals, Buyer shall and shall cause its Affiliates to give at least 30
days’ prior written notice of such intention to dispose of any such Company Books and Records to Seller, and Seller and its Affiliates
shall be given an opportunity, at their cost and expense, to remove and retain all or any part of such Company Books and Records as they
may elect upon reasonable written notice to Buyer.

 

(d)               Notwithstanding
anything to the contrary in the Mutual Confidentiality Agreement, this Agreement or the Transition Services Agreement, Seller and
Buyer acknowledge and agree that certain Company Data has been combined or comingled with other data and information owned by Seller
and its Affiliates (other than the Company Group) that is not Related to the Business (“Comingled Data”).
Consequently, and notwithstanding any transfer of Company Data to Buyer and its Affiliates pursuant to this Agreement and the
Transition Services Agreement, Buyer, on behalf of itself and its Affiliates (including the Company Group after the Closing) and
Seller, on behalf of itself and its Affiliates (other than the Company Group after the Closing) agree that the other Party and its
Affiliates may retain and use such Comingled Data in the ordinary course of business, so long as such Comingled Data is used and
maintained by the Parties and their applicable Affiliates in compliance with Applicable Laws and subject to confidentiality
obligations in this Agreement and the Transition Services Agreement. Buyer’s and its Affiliates’ (including the Company
Group after the Closing) ownership of the Company Data hereunder does not create any ownership right, license, or interest in any
other Data of Seller and its Affiliates that is combined or comingled with the Company Data.

 

    66

     

    

 

Section 5.24 Pre-Closing Restructuring.
Prior to the Closing Date, Seller shall cause the applicable Company Group members to undertake the following actions: (a) Birmingham
Southern Railroad Company shall declare an in-kind dividend, in the form of all of the issued and outstanding equity securities of WGN
(the “WGN Equity”), to the Company, as its sole shareholder and (b) the Company shall declare an in-kind distribution
in the form of the WGN Equity to Seller, as its sole member. For the avoidance of doubt, any intercompany accounts or agreements between
WGN, on the one hand, and the Company Group members, on the other hand, shall be settled or terminated prior to Closing, pursuant to Section
5.09.

 

Section 5.25 Cancelled or Forgiven CARES Act
Payroll Taxes. If at any time after the Closing Date, a Governmental Authority forgives or cancels all or any portion of the Liabilities
or obligations of any Company Group member to pay any Taxes that were included in the calculation of Indebtedness under clause (g) of
the definition of Indebtedness, promptly following and, in any event within five Business Days of, receipt of notice of such forgiveness
or cancellation, Buyer shall pay (or cause the applicable Company Group member to pay) to Seller the amount of such forgiven or cancelled
Taxes to the extent included in the calculation of Indebtedness.

 

Section 5.26 Transition Services
Agreement. From and after the date hereof until Closing, Buyer and Seller shall continue good faith negotiations of (a) any
provisions in the form of Transition Services Agreement attached hereto as Exhibit D or form of Railway Services Agreement
attached hereto as Exhibit B that remain bracketed and footnoted as “Subject to Further Negotiation” and (b) the
Service Schedules (as defined in the Transition Services Agreement). In connection with such good faith negotiation of the Services
Schedules, the Parties will endeavor to agree upon Service Schedules (a) that provide Buyer and its Affiliates (including the
Company Group from and after Closing) with the support services from Seller and its Affiliates necessary to conduct the Business for
the applicable Service Terms (as defined in the Transition Services Agreement) and (b) with fees, to the extent practicable, reflect
the actual cost and expense to Seller for the provision of the support services (which for the avoidance of doubt will include
direct costs attributable to the Seller’s or its Affiliates’ employees directly engaged in performing such services,
including without limitation all salaries, wages, compensation, and employee benefits directly allocated to such employees, or
attributable to the materials and supplies consumed in rendering such services and all indirect costs that relate to the foregoing
direct costs incurred in connection with such services). Within 10 Business Days after the date hereof, Seller shall provide Buyer
with a summary that sets forth all material TSA Consents that have not yet been received by Seller or its Affiliates as of such
date. Until Closing, Seller shall keep Buyer reasonably apprised of the status of each TSA Consent and of the discovery of any
additional TSA Consents not previously made known to Buyer. Seller shall use Commercially Reasonable Efforts to obtain each TSA
Consent prior to Closing, and Buyer shall reasonably cooperate with Seller in obtaining each TSA Consent prior to Closing. To the
extent a TSA Consent is not reasonably expected to be obtained prior to Closing, Seller shall provide notice to Buyer and, at
Buyer’s request, (x) facilitate direct communications between Buyer and the applicable third party service provider and (y)
assist with identifying alternative service providers who may be engaged by Buyer to provide the applicable service.

 

    67

     

    

 

Section 5.27 Permit-Sharing.
From and after the date hereof, Buyer, with reasonable cooperation from Seller, shall diligently pursue obtaining Permits in its own name
or the name of the applicable Company Group member for the discharge of stormwater or air emissions currently occurring from the applicable
Company Group member through Seller’s or its Affiliates’ outfalls or facilities, as applicable under the existing Permits
set forth on Section 5.27 of the Seller Disclosure Schedule (“Existing Shared Permits”), which pursuit shall
include: (a) working cooperatively with Seller to determine the feasibility of having the discharge of stormwater or air emissions, as
applicable, from the applicable Company Group member currently from Seller’s or its applicable Affiliates’ outfalls or facilities
under the Existing Shared Permits be covered by separate Permits (“New Permits”) and (b) if such determination is made,
filing applications to obtain New Permits and using Commercially Reasonable Efforts to obtain New Permits, provided that Buyer shall not
be required to construct standalone storm water discharge or air emissions facilities or otherwise incur unreasonable costs and expenses
to obtain a New Permit. Notwithstanding the foregoing, Buyer shall not be required to incur capital expenditures prior to the Closing
in connection with obtaining New Permits. Until a New Permit is obtained for a stormwater discharge or air emission, and for any discharge
or emission for which a New Permit cannot be obtained in accordance with the preceding terms of this Section 5.27, from and after
the Closing, Seller and its applicable Affiliates shall provide for coverage of the discharge of stormwater or air emissions, as applicable,
from the applicable Company Group member through Seller’s or its applicable Affiliates’ outfalls or facilities, as applicable,
with the Existing Shared Permits, and any amended or subsequent Permits needed for such discharge of stormwater or air emissions, which
coverage shall be on commercially reasonable terms set forth in one or more temporary permit-sharing agreements that Buyer and Seller
shall continue to negotiate and shall finalize between the date hereof and the Closing, and which temporary permit-sharing agreements
shall be renewed provided Buyer or the applicable Company Group Member continues to pursue obtaining New Permits that would reasonably
be expected to be issued in accordance with this Section 5.27.

Employee Matters

 

Section 6.01 Maintenance of Compensation
and Benefits. During the period commencing on the Closing Date and ending on December 31, 2022 (the “Continuation
Period”), Buyer shall (or shall cause its Affiliates to) provide each Company Employee who is actively employed by the
Company Group immediately prior to the Closing and that is not covered by a collective bargaining agreement: (a) an annual base
salary, commission opportunities and short- term cash incentive compensation opportunities that in the aggregate are at least equal
in terms of amount to the annual base salary, commission opportunities and short- term cash incentive compensation opportunities
provided to such Company Employee as of immediately prior to the Closing Date, (b) employee benefits, including health and
welfare and retirement benefits (but excluding severance, equity incentive compensation, defined benefit plans and retiree welfare
obligations), that are no less favorable in the aggregate than such benefits provided to such Company Employee immediately prior to
the Closing Date, and (c) severance protections and entitlements as set forth on Section 6.01 of the Seller Disclosure
Schedule.

 

    68

     

    

 

Section 6.02 Collective Bargaining Agreements.
Buyer shall (or cause its Affiliates to) continue in place and abide by any collective bargaining agreement covering a Company Employee
as of the Closing Date including, but not limited to, terms included in any such collective bargaining agreements governing any defined
benefit plan and post-termination welfare benefits. Notwithstanding anything to the contrary in this Article 6, the terms and conditions
of employment for any Company Employee covered by a collective bargaining agreement shall remain in effect in accordance with the terms
of any such agreement post-Closing.

 

Section 6.03 Company Employees. Except as
set forth on Section 6.03 of the Seller Disclosure Schedule, Seller shall, or shall cause its Affiliates (including the Company
Group) to (i) immediately prior to the Closing Date, take all actions necessary to transfer the employment of all employees (other than
Inactive Company Employees) who primarily provide services to the Company Group, but are not employed by a member of the Company Group,
to the Company Group and (ii) prior to the Closing Date, take all actions necessary to transfer the employment of all Inactive Company
Employees and all employees employed by the Company Group that primarily provide services to the Seller or one of its Subsidiaries, other
than the Company Group, to Seller or one of its Affiliates (other than a member of the Company Group). Buyer shall (or shall cause one
of its Affiliates to) offer employment to any Inactive Company Employee who is able to return to active work within six months following
the Closing.

 

Section 6.04 Service Credit. Buyer shall
(or shall cause its Affiliates to) grant each Company Employee full credit for all prior service with Seller, the Company or any of their
respective Affiliates or predecessors of any such entity for all purposes, including for purposes of determining eligibility to participate,
level of benefits, vesting, early retirement eligibility and benefit plan accruals, under each employee benefit plan sponsored or maintained
by Buyer or any of its Affiliates in which such Company Employee is eligible to Participate and in accordance with Applicable Law, including
those providing defined benefit pension and/or post-termination welfare benefits (to the extent the Buyer, the Company or any Subsidiary
of the Company maintains such benefits), to the same extent such service would be recognized by Seller or its applicable Affiliate (including
the Company) under any similar employee benefit plan immediately prior to the Closing; provided, however, that such credit
shall not result in a duplication of benefits.

 

    69

     

    

 

Section 6.05 Welfare Plans. As of the
Closing Date, each Company Employee shall cease participation in the health and welfare benefit plans of Seller (each, a
 “Seller Welfare Plan”) and commence or continue participation in the health and welfare benefit plans maintained
by Buyer or its Affiliates (which, for the avoidance of doubt, after the Closing shall include any Company Benefit Plans). Benefits
in respect of all welfare plan claims incurred by Company Employees on or after the Closing shall be provided by Buyer or its
Affiliates. For purposes of this Section 6.05, a claim shall be deemed “incurred” on the date that the event that
gives rise to the claim occurs (for purposes of life insurance, severance, sickness, accident and disability programs) or on the
date that treatment or services are provided (for purposes of healthcare programs). For each Company Employee who immediately
prior to the Closing Date participated in a healthcare and/or dependent care flexible spending arrangement (an
 “FSA”) under a section 125 plan of Seller, Buyer shall provide the same level of coverage under an equivalent
plan of Buyer or its Affiliate and shall treat the Company Employees as if their participation had been continuous from the
beginning of the Seller’s plan year. As soon as practicable after the Closing, Seller shall transfer to Buyer (or its
applicable Affiliate(s)) a cash lump sum equal to the total amount that Company Employees have contributed to the applicable FSAs of
Seller through the Closing Date for the plan year that includes the Closing, less all amounts that have been paid from such FSAs
through the Closing Date for eligible expense claims incurred by the Company Employees in the plan year that includes the Closing
(such difference, the “FSA Amount”). If the FSA Amount is less than $0, as soon as practicable after the Closing,
Buyer shall transfer to Seller a cash lump sum equal to all amounts that have been paid from Seller’s FSAs through the Closing
Date for eligible claims incurred by the Company Employees in the plan year that includes the Closing, less the total amount that
Company Employees have contributed to Seller’s FSAs through the Closing Date for the plan year that includes the Closing. The
Company Employees’ salary reduction elections shall be taken into account for the remainder of Buyer’s plan year as if
made under Buyer’s plan, and Buyer’s FSA shall reimburse eligible expenses incurred by Company Employees at any time
during the Seller’s plan year, including expenses incurred before the Closing Date, up to the amount of the employee’s
election and reduced by amounts previously reimbursed by the Seller’s FSA.

 

Section 6.06 Pre-Existing Conditions and Co-Payments.
Buyer shall (or shall cause its Affiliates to) use Commercially Reasonable Efforts to:

 

(a)              
waive all limitations as to pre-existing conditions, exclusions, actively-at-work requirements and waiting periods with respect
to participation and coverage requirements applicable to the Company Employees (and their eligible dependents) under any health and welfare
plans in which the Company Employees are eligible to participate on or after the Closing Date to the extent that such limitations were
waived or met under the applicable Seller Welfare Plan or health and welfare Company Benefit Plans as of the Closing Date; and

 

(b)              
provide each Company Employee with credit for the dollar amount of all co-payments, deductibles and similar expenses incurred
by such Company Employee (or any covered dependent thereof) prior to the Closing Date in satisfying any applicable deductible or out-of-pocket
requirements under any health and welfare plans in which such Company Employees are eligible to participate on or after the Closing Date
in the plan year in which the Closing occurs.

 

Section 6.07 WARN Act. Buyer shall be
solely responsible for and assume all liabilities for the provision of notice or payment in lieu of notice and any applicable
penalties under the WARN or any similar Applicable Law arising after the Closing Date as a result of the transactions contemplated
by this Agreement. Prior to the Closing, Seller shall provide Buyer a schedule which shall, as of the Closing Date, set forth a list
of each Company Employee who has experienced an “employment loss” (as defined in WARN) involuntarily within the prior
90-day period, together with such employee’s work location.

 

    70

     

    

 

Section 6.08 U.S. Defined Contribution Plans.
On or prior to the Closing Date, Seller shall transfer sponsorship of the Transtar, LLC Savings Plan for Represented Employees (the
 “Transtar 401(k) Plan”) to the Company. Buyer shall continue to make available to Company Employees the Transtar 401(k)
Plan for the duration of the Continuation Period, with terms and conditions equal to or more favorable than those terms and conditions
contained in the Transtar 401(k) Plan prior to the Closing.

 

Section 6.09 U.S. Defined Benefit Plans. Effective
as of the Closing Date, if required by the terms of an applicable collective bargaining agreement, Buyer or its Affiliate shall adopt
and establish a (or otherwise designate an existing) defined benefit plan that is intended to qualify under Section 401(a) of the Code
and a related trust that is exempt under Section 501(a) of the Code (such plan and trust, the “Buyer DB Plan”). The
Buyer DB Plan shall have terms and features (including benefit accrual provisions) that are substantively identical to the United States
Steel Corporation Plan for Employee Pension Benefits (Revision of 2003) (the “Seller DB Plan”) as it pertains to Company
Employees such that, for the avoidance of doubt, the Seller DB Plan as it pertains to Company Employees is replicated in all material
respects by the Buyer DB Plan (but for the avoidance of doubt, not for purposes of plan administration). Buyer shall cause the Buyer DB
Plan to credit each Company Employee who as of the Closing is an active participant in the Seller DB Plan with full past service credit
for eligibility, vesting, benefit accrual, determination of eligibility for early retirement and other subsidized benefits, and for all
other purposes under the Seller DB Plan where service is taken into account from his or her date of employment with Seller and its Affiliates
(and predecessors) to the extent such service was credited for such purpose on behalf of such Company Employees under the Seller DB Plan.
The accrued benefit of each Company Employee under the Buyer DB Plan as of the Closing Date, taking into account service with Seller and
its Affiliates (and predecessors) but not taking into account the benefit offset described below, will be at least as great as the accrued
benefit of such Company Employee under the Seller DB Plan immediately prior to the Closing Date. The benefit of each Company Employee
under the Buyer DB Plan shall be “offset” by such Company Employee’s accrued benefit under the Seller DB Plan. Each
Company Employee who is an active participant in the Seller DB Plan immediately prior to the Closing shall become a participant in the
Buyer DB Plan as of the Closing and shall cease to be an active participant in the Seller DB Plan as of the Closing. Buyer or its Affiliate
shall be solely responsible for taking all necessary, reasonable and appropriate actions (including, if applicable, the submission of
the Buyer DB Plan to the IRS for a determination of tax-qualified status) to establish, maintain, and administer the Buyer DB Plan so
that it is qualified under Section 401(a) of the Code and the related trust is exempt under Section 501(a) of the Code. For the avoidance
of doubt, Seller shall: (a) retain all assets held in trust on behalf of the Seller DB Plan or otherwise underlying the Seller DB Plan,
and (b) retain all liabilities for accruals, including accruals on behalf of Company Employees, when such accruals are for periods occurring
prior to the Closing Date. Prior to the Closing Date, Seller will deliver to Buyer an amendment to the Seller DB Plan, subject to Buyer’s
review and reasonable comments, reflecting the mutually agreed upon coordination of benefits between the Buyer DB Plan and the Seller
DB Plan, as set forth on Section 6.09 of the Seller Disclosure Schedule.

 

    71

     

    

 

Section 6.10 Accrued Vacation and Sick Leave.
Buyer shall (or shall cause its Affiliates to) recognize and assume the liability with respect to accrued but unused vacation time and
sick leave for all Company Employees; provided that in any jurisdiction where payment of the value of accrued but unused vacation
time to Company Employees is required by Applicable Law as of the Closing Date, Seller will pay, or cause to be paid, all accrued but
unused vacation time to such Company Employees as soon as reasonably practicable after the Closing Date, and Buyer shall promptly, but
in no event more than 15 days after being notified by Seller, reimburse Seller in respect of any such payment.

 

Section 6.11 Workers Compensation. Buyer
shall be responsible for providing benefits in respect of all claims for workers compensation or benefits under the Federal Employees
Liability Act and shall assume any related liabilities, in each case with respect to Company Employees and former employees of the Company;
provided, however, that if Applicable Law does not permit Buyer or its Affiliates to provide such benefits with respect
to injuries or illnesses that arose prior to the Closing Date, Seller shall be responsible for providing, or causing to be provided, such
benefits and Buyer shall promptly, but in no event more than 15 days after being notified by Seller, reimburse Seller in respect
of any such benefits.

 

Section 6.12 Existing Agreements. Prior
to the Closing, Buyer will expressly assume all obligations of Seller pursuant to any special incentive awards with Company Employees,
as set forth on Section 6.12 of the Seller Disclosure Schedule.

 

Section 6.13 No Third Party Beneficiaries. Nothing
in this Article 6, express or implied, (a) is intended to or shall confer upon any Person other than the Parties, including
any Company Employee and Company Employee representative, any right, benefit or remedy of any nature whatsoever under or by reason of
this Agreement, (b) shall establish, or constitute an amendment, termination or modification of, or limit the ability of the Company,
Seller, Buyer or any of their Affiliates to amend, terminate or otherwise modify any benefit plan, or (c) shall create any obligation
on the part of Seller or any of their respective Affiliates to employ any Company Employee for any period following the Closing Date.

 

Section 6.14 Cooperation. From and
after the date hereof, Seller shall provide Buyer and its designees with all information to the extent reasonably necessary to allow
Buyer and its Affiliates to comply with their obligations under this Article 6, including to establish employee benefit plans
consistent with Buyer’s obligations under this Article 6, and shall reasonably cooperate with Buyer and its Affiliates
to use Commercially Reasonable Efforts to assist in establishing insurance and other service provider relationships with respect to
such plans (including in connection with the Transition Services Agreement; provided, however, that in the event of a
conflict between Seller’s obligations under this Section 6.14 and Seller’s obligations pursuant to the Transition
Services Agreement, the Transition Services Agreement shall govern). Such reasonable cooperation shall include, but shall not
necessarily be limited to, (a) providing reasonable access to documentation and other information associated with the terms and
administration of the Employee Benefit Plans, (b) providing reasonable access to employees of Seller and its Affiliates and other
third-parties that have operational knowledge of the Employee Benefit Plans and (c) facilitating introductions to the vendors of
such plans. Notwithstanding the foregoing, Seller shall not be required to provide or cause to be provided access to or to
disclose or cause to be disclosed information where such access or disclosure would jeopardize the attorney-client or other
privilege, contravene any Applicable Law or Contract or contravene any confidentiality undertaking.

or cause to be prepared, at, in the case of income Tax Returns, Seller’s cost and expense and, in the case of non-income Tax Returns,
the Company Group’s cost and expense, any Tax Return of any Company Group member for any Pre-Closing Tax Period that is required
to be filed, and the original due date (including extensions) for which is, after the Closing and Buyer shall prepare, or cause to be
prepared, any Tax Return of any Company Group member for any Straddle Period that is required to be filed, and the original due date (including
extensions) for which is, after the Closing. All such Tax Returns shall be prepared in accordance with past custom and practice of the
applicable Company Group member, except to the extent otherwise required by Applicable Law or this Agreement. The Party required to prepare
any such Tax Return for income Taxes shall provide the other Party with a draft of any such Tax Return not less than 30 days prior to
the due date (including extensions) for such Tax Return (unless the due date for any such Tax Return is within 30 days of the Closing
Date, in which case the preparing Party shall provide such draft to the other Party as soon as reasonably practicable) and the preparing
Party shall accept and incorporate into any such Tax Return any reasonable comments submitted in writing by the non-preparing Party within
20 days of (or, if the due date for any such Tax Return is within 30 days of the Closing Date, as soon as reasonably practicable after)
the preparing Party’s delivery of such Tax Return to the non-preparing Party. Buyer shall timely file or cause to be timely filed
any Tax Return prepared pursuant to this Section 7.01 (for the avoidance of doubt, none of which shall include any Seller Group
Tax Return) and timely pay, or cause to be timely paid, any Taxes shown as due and owing on any such Tax Return; provided, however,
that Seller shall timely reimburse Buyer for the Taxes for which Seller is liable pursuant to Section 9.02(a)(iii) but which are
remitted in respect of any Tax Return to be filed by the Buyer pursuant to this Section 7.01 upon the written request of Buyer
setting forth the computation of the amount owed by Seller. For the avoidance of doubt, such reimbursement obligations shall not be subject
to the limitations on indemnification set forth in Article 9 (except for the last sentence of Section 9.03(a), Sections
9.06(b), 9.06(c) and 9.06(d)). Notwithstanding anything to the contrary in this Agreement (including Section 5.04
or any provision of this Article 7), in no event shall Buyer or any Affiliate of Buyer (including, after the Closing, any Company
Group member) have any right to review, participate in the preparation of or otherwise review, obtain or have access to any Seller Group

Group member) of any written notice of any audit, examination, claim, investigation or other proceeding relating to Taxes of any
Company Group member (each, a “Company Group Tax Claim”) for any Pre-Closing Tax Period or any Straddle Period; provided
that failure to comply with this provision shall not affect Buyer’s right to indemnification under this Agreement except to
the extent such failure shall have adversely prejudiced Seller’s ability to contest any such Tax liabilities. In connection
with such notice provided by Buyer to Seller pursuant to this Section 7.02(a), Buyer shall provide Seller with any relevant
written correspondence or other materials received from the relevant Taxing Authority with respect to any such Group Company Tax
Claim.

Seller shall have the right, but not the obligation, to control, including the selection of counsel at Seller’s cost and
expense, any Company Group Tax Claim for a Pre-Closing Tax Period (provided that Seller shall have first notified Buyer in writing
of Seller’s intention to do so and of the identity of counsel, if any, chosen by Seller in connection therewith (it being understood
by the Parties that Seller has already notified Buyer of its intention to control the matters set forth in clauses (a), (b) and (c) of
Section 3.20(a)(v)(1) of the Seller Disclosure Schedule)), and Buyer shall have the right, but not the obligation, to control any Company
Group Tax Claim for a Pre-Closing Tax Period that Seller does not elect to control pursuant to this Section 7.02(b) and Buyer shall
control any Company Group Tax Claim for any Straddle Period; provided that the Party that controls a Company Group Tax Claim pursuant
to this Section 7.02(b) shall (i) keep the other Party informed on a reasonable basis with respect to the status of any such Company
Group Tax Claim, (ii) allow the other Party to participate (at such Party’s expense) on a reasonable basis in any such Company Group
Tax Claim and (iii) not settle any such Company Group Tax Claim without the prior written consent of the other Party (such consent not
to be unreasonably withheld, conditioned or delayed).

 

(c)              
Notwithstanding anything to the contrary in this Agreement, in no event will Buyer or any Affiliate of Buyer (including, after
the Closing, any Company Group member) have any right to control, participate or otherwise be involved in or have access to any information
with respect to any audit, examination or other proceeding relating to any Seller Group Tax Return or otherwise with respect to Taxes
of any Seller Group or any Seller Group Tax Return.

 

(d)              
In the event of any inconsistency between this Section 7.02 and Section 9.04, this Section 7.02 shall control.

 

Section 7.03 Transfer Taxes. All Transfer
Taxes incurred in connection with transactions contemplated by the Transaction Agreements (including, for the avoidance of doubt, any
real property transfer Tax and any similar Tax) shall be borne 50% by Buyer and 50% by Seller; provided that Transfer Taxes arising
as a result of (a) the transactions contemplated by Section 5.15 (Redemption of USS Portfolio Shares) and Section 5.24
(Pre-Closing Restructuring) and (b) the transfer of real and personal property pursuant to Section 5.20 (Real Estate
Matters), shall be borne entirely by Seller and the Transfer Taxes arising as a result of the transactions contemplated by Section
5.13(b) shall be borne entirely by Buyer. All Tax Returns with respect to Transfer Taxes shall be filed by the Party required to file
the Tax Return under Applicable Law, and Buyer and Seller, as applicable, shall reimburse the filing Party for any Transfer Taxes that
are borne by Buyer or the Seller, respectively, pursuant to this Section 7.03. The parties shall cooperate on a reasonable basis
in connection with the preparation and filing of any Tax Returns for Transfer Taxes. For the avoidance of doubt, such reimbursement obligations
shall not be subject to the limitations on indemnification set forth in Article 9 (except for the last sentence of Section 9.03(a),
Sections 9.06(b), 9.06(c) and 9.06(d)).

 

    74

     

    

 

Section 7.04 Tax Refunds. Buyer shall promptly
pay or cause to be paid to Seller an amount equal to any refund (or any credit in lieu of any refund) of Taxes of any Company Group member,
together with interest thereon received from the applicable Taxing Authority, received or obtained after the Closing with respect to
any Pre-Closing Tax Period or the portion of any Straddle Period ending on the Closing Date, net of any reasonable cost to Buyer or its
Affiliates attributable to the receipt and paying over of such refund; provided, however, such refund shall be property
of Buyer to the extent such refund (i) arises from the carryback of an item of deduction or loss from a period beginning after the Closing
Date or, with respect to any Straddle Period, the portion of such period beginning after the Closing Date, to a Pre-Closing Tax Period
or the portion of any Straddle Period ending on the Closing Date, or (ii) was taken into account in Closing Net Working Capital.

Group member shall have any rights or liability thereunder on or after the Closing Date.

 

Section 7.06 Cooperation on Tax Matters. Buyer
and Seller shall, and shall cause their respective Affiliates (including, in the case of Buyer, the Company Group members after the Closing
Date) to, cooperate, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of any
Tax Return and the preparation for and defense against any audit, examination or other proceeding with respect to Taxes relating to any
Company Group member. Such cooperation shall include the provision of records and information that are reasonably necessary for the preparation
of any such Tax Return or for any such audit, examination or other proceeding and making employees available on a mutually convenient
basis to provide additional information and explanation of any materials provided hereunder.

 

Section 7.07 Section 338(h)(10) Election.
At the request of Buyer, Seller and Buyer shall make one or more joint elections under Section 338(h)(10) of the Code (and under
similar provisions of state or local Tax Law) with respect to the purchase and sale of the Interests pursuant to this Agreement or any
deemed purchase of shares of the Subsidiaries of the Company (each, a “Section 338(h)(10) Election”), provided
that Buyer shall, within 60 days of the Closing Date provide written notice to Seller of Buyer’s decision to make one or more Section 338(h)(10)
Elections and Buyer shall include with such notice a draft IRS Form 8023 (and any form necessary for state or local Tax purposes) for
each such Section 338(h)(10) Election for Seller’s review and approval (such approval not to be unreasonably withheld, conditioned
or delayed) (the “Section 338(h)(10) Election Notice”). If Buyer timely provides the Section 338(h)(10) Election
Notice pursuant to this Section 7.07, each of Buyer and Seller agrees that neither it nor any of its Affiliates shall take, or

any Section 338(h)(10) Elections.

Section 7.08 Straddle Periods. For
purposes of this Agreement, Taxes of any Company Group member for any Straddle Period shall be allocated to the portion of the
Straddle Period ending on the Closing Date, on the one hand, and the portion of the Straddle Period beginning on the day after the
Closing Date, as follows: (a) in the case of Taxes based upon income, gains, deduction, loss, sales, proceeds, profits, receipts,
wages, compensation or similar items, on an interim closing of the books basis as if the Straddle Period ended at the close of the
Closing Date (provided, however, that any exemption, depreciation, amortization or other deductions, credit or other
item that is calculated on an annual basis shall be allocated on a per diem (daily) basis) and (b) in the case of any other Taxes
such as real or personal property Taxes, on a per diem (daily) basis. For the avoidance of doubt, any item of income, gain, loss or
deduction for a Straddle Period that is realized on the transactions contemplated hereby deemed to occur as a result of the Section
338(h)(10) Elections shall be allocated to the portion of any such Straddle Period ending on the Closing Date.

 

Section 7.09 Buyer Tax Acts. Without the
prior written consent of Seller (in the case of clause (b) or (c), such consent not to be unreasonably withheld, conditioned or delayed),
Buyer shall not, and shall cause its Affiliates (including, after the Closing, the Company Group members) not to: (a) take any action
on the Closing Date after the Closing other than in the ordinary course of business or as otherwise expressly contemplated by the Transaction
Agreements or as required by Applicable Law; (b) file (other than in accordance with Section 7.01) or re-file, amend or otherwise
modify any Tax Return of any Company Group member for any Pre-Closing Tax Period or any Straddle Period or make, change or revoke any
Tax election for a Company Group member with retroactive effect to any Pre-Closing Tax Period or any Straddle Period (other than any Section
338(h)(10) Election made in accordance with Section 7.08); or (c) initiate any voluntary disclosure or similar program, agreement
or arrangement, or agree to extend or waive the statute of limitations, in each case with respect to Taxes of any Company Group member
for any Pre-Closing Tax Period. To the maximum extent permitted by Applicable Law, (x) Buyer shall, and shall cause the Company Group
members to, waive or otherwise forego any or all rights to carryback any net operating loss, capital loss, or other similar attribute
for U.S. federal (and applicable state and local) income tax purposes to any Seller Group Tax Return for a Pre-Closing Tax Period or any
Straddle Period and (y) Buyer shall not, and shall cause the Company Group members not to, file or otherwise make any election to carryback
any such tax attribute to any Seller Group Tax Return for a Pre-Closing Tax Period or any Straddle Period.

 

Section 7.10 Other Tax Matters. Notwithstanding
anything to the contrary in this Agreement, the covenants and obligations set forth in this Article 7 shall survive until 60 days
after the expiration of all applicable statutes of limitation (taking into account extensions thereof).

and warranties of the Parties contained in this Agreement shall survive the Closing for a period of 12 months following the Closing Date.
The covenants and agreements of the Parties contained in this Agreement, or in any certificate or other writing delivered pursuant hereto
or in connection herewith, shall survive in accordance with their terms. Notwithstanding the preceding sentences, any breach of covenant,
agreement, representation or warranty in respect of which indemnity may be sought under this Agreement shall survive the time at which
it would otherwise terminate pursuant to the preceding sentence if written notice of the inaccuracy thereof giving rise to such right
of indemnity shall have been given to the Party against whom such indemnity may be sought prior to such time.

 

Section 9.02 Indemnification.

 

(a)               Effective
at and after the Closing, Seller hereby indemnifies Buyer and its Affiliates against and agrees to hold each of them harmless from
any and all Damages actually suffered by Buyer or any of its Affiliates arising out of (i) any misrepresentation or breach of any of
the representations or warranties of Seller contained in this Agreement, (ii) any breach of covenant or agreement made or to be

    78

     

    

 

(b)              
Effective at and after the Closing, Buyer hereby indemnifies Seller and its Affiliates against and agrees to hold each of them
harmless from any and all Damages actually suffered by Seller or any of its Affiliates arising out of any (i) misrepresentation or breach
of any of the representations or warranties of Buyer contained in this Agreement, (ii) breach of covenant or agreement made or to be performed
by Buyer pursuant to this Agreement, (iii) WARN or any similar Applicable Law arising as a result of the transactions contemplated by
this Agreement to the extent Buyer is responsible for such liabilities pursuant to Section 6.07 or (iv) payments by Seller to Canadian
National Railway, Grand Trunk Corporation, Wisconsin Central, Ltd. or any of their respective Affiliates or any out-of-pocket costs and
expenses incurred by Seller or its Affiliates, in each case, arising from Seller’s obligations in Article 3 and 5 of that certain
Omnibus Consent and Amendment Agreement, dated May 19, 2021, by and among Seller, GRW, Canadian National Railway, Grand Trunk Corporation
and Wisconsin Central, Ltd., but excluding any such payments in connection with the US Smelter Existing Claims.

 

(c)              
For purposes of determining any inaccuracy in or breach of the representations and warranties pursuant to Section 9.02(a)
and calculating any resulting Damages thereunder, any reference to “Material Adverse Effect”, “material”, “all
material respects” and similar qualifications in the representations, warranties, covenants and agreements in this Agreement shall
be disregarded; provided, however, that references to “Material Adverse Effect” in Section 3.09(b) and
any use of the term “Material Contract”, “Material Customer” or “Material Supplier” in Article
3 shall not be disregarded.

 

(d)              
Any indemnification pursuant to this Section 9.02 shall be subject to the procedures and limitations set forth in this Article
9, and if applicable, Section 5.21.

 

Section 9.03 Limitations of Liabilities.
The party making a claim under this Article 9 is referred to as the “Indemnified Party,” and the party against
whom such claims are asserted under this Article 9 is referred to as the “Indemnifying Party.” The indemnification
provided for in Section 9.02 shall be subject to the following limitations:

 

(a)              
Seller shall not be liable to Buyer for indemnification pursuant to Section 9.02(a)(i) until the aggregate amount of all
Damages in respect of indemnification pursuant to Section 9.02(a)(i) exceeds $2,400,000 (the “Deductible”),
in which event Seller shall only be required to pay or be liable for Damages in excess of the Deductible; provided, however, that
in no event shall Seller’s aggregate liability pursuant to Section 9.02(a)(i) exceed $2,400,000 (the “Cap”).
Notwithstanding the foregoing, neither the Deductible nor the Cap shall apply to any indemnification claim made by any Indemnified Party
based upon or arising out of any Fraud. Other than in the case of Fraud, in no event shall Seller’s aggregate liability under this
Agreement exceed an amount equal to the Purchase Price.

 

(b)              
Nothing in this Section 9.03 shall be deemed to limit any rights of the Buyer Indemnified Parties as against the R&W
Insurer under the R&W Insurance Policy.

 

    79

     

    

 

Section 9.04 Third Party Claim Procedures.

 

(a)              
The Indemnified Party agrees to give prompt notice in writing to the Indemnifying Party of the assertion of any claim or the commencement
of any Legal Proceeding by any third party (“Third Party Claim”) in respect of which indemnity may be sought under
Section 9.02. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking
into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve
the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have adversely prejudiced the Indemnifying
Party. The Indemnifying Party has received notice of the Existing Asbestos Litigation and US Smelter Existing Claims.

 

(b)              
Subject to Seller’s right to control any Existing Asbestos Litigation or US Smelter Existing Claims in accordance with Section
5.21, the Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, subject to the limitations
set forth in this Section 9.04, shall be entitled to control and appoint lead counsel for such defense, in each case at its own
expense; provided, however, that the Indemnifying Party shall not be entitled to assume control of a Third Party Claim if
(i) the Third Party Claim relates to or arises in connection with any criminal Legal Proceeding, indictment or allegation, (ii) the Third
Party Claim seeks injunctive or other equitable relief, or, if adversely determined, would impair in any material respect the financial
condition, business, operations, reputation or prospects of Buyer or its Subsidiaries (including the Company Group), (iii) the indemnification
obligation of the Indemnifying Party (after the application, if applicable, of any cap on Damages) is determined in good faith by Buyer
to be less than the potential maximum Damages amount of the Third Party Claim at issue, or (iv) with respect to the Third Party Claim,
the Indemnified Party is Buyer or any of its Affiliates and is seeking, or reasonably expects to receive, recovery under the R&W Insurance
Policy or a reductions in the retention thereunder.

 

(c)              
If the Indemnifying Party shall assume the control of the defense of any Third Party Claim in accordance with the provisions of
this Section 9.04, (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall
not be unreasonably withheld, conditioned or delayed) before entering into any settlement of such Third Party Claim, if the settlement
does not expressly unconditionally release the Indemnified Party and its Affiliates from all liabilities and obligations with respect
to such Third Party Claim or the settlement imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates
and (ii) the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel
of its choice for such purpose. The fees and expenses of such separate counsel shall be paid by the Indemnified Party.

 

(d)              
The Indemnified Party shall not admit liability in respect of any Third Party Claim, nor enter into any settlement of such Third
Party Claim, without the prior written consent of the Indemnifying Party.

 

(e)              
Each Party shall cooperate, and cause its Affiliates to cooperate, in the defense or prosecution of any Third Party Claim and shall
furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings,
trials or appeals, as may be reasonably requested in connection therewith.

 

    80

     

    

 

Section 9.05 Direct Claim Procedures. In
the event an Indemnified Party has a claim for indemnity under Section 9.02 against an Indemnifying Party that does not involve
a Third Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party. Such notice
shall set forth in reasonable detail such claim and the basis for indemnification (taking into account the information then available
to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations
hereunder, except to the extent such failure shall have adversely prejudiced the Indemnifying Party. Such notice shall describe the claim
in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably
practicable, of the Damages that have been or may be sustained by the Indemnified Party. Following such notice, the Parties shall proceed
in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved in
accordance with Section 11.11.

 

Section 9.06 Calculation of Damages.

 

(a)              
The amount of any Damages payable under Section 9.02 by the Indemnifying Party shall be net of any amounts actually recovered
by the Indemnified Party under applicable insurance policies, or from any other Person alleged to be responsible therefor. Subject to
the rights of the R&W Insurer as set forth in the R&W Insurance Policy, if the Indemnified Party receives any amounts under applicable
insurance policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the
Indemnifying Party, then to the extent the Indemnified Party’s total recovery exceeds it Damages with respect to the underlying
event, such Indemnified Party shall promptly reimburse the Indemnifying Party for any such excess not to exceed the amount received by
the Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such amount.

 

(b)              
The Indemnifying Party shall not be liable under Section 9.02 for any Damages relating to any matter to the extent that
such matter has been taken into account in connection with the Purchase Price adjustment under Section 2.06.

 

(c)              
Each Indemnified Party must mitigate in accordance with Applicable Law any Damages for which such Indemnified Party seeks indemnification
under this Agreement. If such Indemnified Party mitigates its Damages after the Indemnifying Party has paid the Indemnified Party under
any indemnification provision of this Agreement in respect of those Damages, the Indemnified Party must notify the Indemnifying Party
and pay to the Indemnifying Party the extent of the value of the benefit to the Indemnified Party of that mitigation (less the Indemnified
Party’s reasonable costs of mitigation) within two Business Days after the benefit is received.

 

(d)              
Buyer and Seller agree to treat any indemnification payment made under this Agreement as an adjustment to the Purchase Price for
federal income tax purposes including, as applicable, a corresponding adjustment to Final Allocation Schedule, except to the extent otherwise
required by Applicable Law.

 

Section 9.07 Assignment of Claims. If
the Indemnified Party receives any payment from an Indemnifying Party in respect of any Damages pursuant to Section 9.02 and
the Indemnified Party could have recovered all or a part of such Damages from a third party (a “Potential Contributor”)
based on the underlying claim asserted against the Indemnifying Party, subject to the rights of the R&W Insurer as set forth in
the R&W Insurance Policy, the Indemnified Party shall assign such of its rights to proceed against the Potential Contributor as
are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

 

    81

     

    

 

Section 9.08 No Right to Set-Off. Buyer,
on its own behalf and on behalf of its Affiliates (including after Closing, the Company Group members), hereby unconditionally and irrevocably
waives any rights of set-off, netting, offset, recoupment, or similar rights that Buyer and its Affiliates have or may have with respect
to the payment of the Purchase Price or any other payments to be made by Buyer pursuant to this Agreement or by Buyer, any Company Group
member or their respective Affiliates pursuant to any Transaction Agreements. In this connection, each Party hereby agrees, on behalf
of itself and all of its Affiliates, that in no event shall any Indemnified Party be entitled to indemnification hereunder in respect
of any claim, item or other matter unless and until such claim, item or other matter has been Finally Determined.

 

Section 9.09 Debt Financing Source Liability.
Notwithstanding anything herein to the contrary, Seller and its Affiliates shall not have any claim against any Debt Financing Source
or any Debt Finance Related Party, nor shall any Debt Financing Source or any Debt Finance Related Parties have any liability whatsoever
to Seller and its Affiliates, in connection with the Debt Financing, the Debt Commitment Letter or in any way relating to this Agreement
or any of the transactions or services contemplated thereby or hereby, whether at law, in equity, in contract, in tort or otherwise. Under
no circumstances shall any Party to this Agreement be entitled to recovery from any Debt Financing Source consequential, indirect, punitive,
exemplary or special damages arising out of or relating to the transactions contemplated by this Agreement, the Debt Commitment Letter
or the Debt Financing.

 

Section 9.10 Exclusivity. Except in the
case of Fraud, after the Closing, Section 5.18, Section 6.07, Section 9.02 and Section 11.11 and the R&W
Insurance Policy shall provide the exclusive remedy for any misrepresentation, breach of warranty, covenant or other agreement or other
claim arising out of this Agreement or the transactions contemplated hereby (other than claims with respect to the determination of the
Adjustment Amount, which shall be resolved in accordance with Section 2.06) or any Legal Proceedings against, or Damages suffered
by, Buyer or its Affiliates relating to the Company Group, the Interests or the Business or any actions taken or failed to be taken by
any of the Released Parties in any capacity related to Company Group, the Interests or the Business occurring or arising on or prior to
the Closing Date. Notwithstanding anything to the contrary herein, the exclusive sources of recovery for Buyer and its Affiliates for
indemnification claims under Section 9.02(a)(iii) shall be recourse against (i) first, to the extent coverage is available thereunder,
to the R&W Insurance Policy, and (ii) thereafter, to the extent Buyer or its Affiliates are unable to recover all or any portion of
such Damages from and against the R&W Insurance Policy for whatever reason (including the application of any self-insured retention),
Seller; provided that, for the avoidance of doubt, if the subject matter of such indemnification claim is expressly excluded from
coverage pursuant to the R&W Insurance Policy, Buyer and its Affiliates shall have no obligation to first look to the R&W Insurance
Policy for recovery of such Damages.

that if the Closing shall not have occurred prior to such date and all of the conditions to closing set forth in Article 8, other
than the conditions set forth in Section 8.01(a) or Section 8.02(d) have been satisfied or waived by the Parties entitled

by either Seller or Buyer if any court of competent jurisdiction or other Governmental Authority shall have issued an Order or
taken any other action enjoining, prohibiting or rendering illegal the consummation of the transactions contemplated hereby and such Order
or other action shall have become final and non-appealable; provided that the right to terminate this Agreement pursuant to this
Section 10.01(a)(iii) shall not be available to any Party whose breach of any provision of this Agreement results in such Order
or action;

 

(iv)            
by Buyer if there is any material breach of any representation, warranty, covenant or agreement on the part of Seller set forth
in this Agreement, such that the conditions specified in Section 8.01 or Section 8.02 would not be satisfied at the Closing
(a “Terminating Seller Breach”), except that, if such Terminating Seller Breach is curable by Seller, then, for a period
of up to 30 days after receipt by Seller of notice from Buyer of such breach (the “Seller Cure Period”) such termination
shall not be effective and the End Date shall be automatically revised to be the later of the original End Date and the first Business
Day following the end of the Seller Cure Period, and such termination shall become effective only if the Terminating Seller Breach is
not cured within the Seller Cure Period;

 

    83

     

    

 

(v)               by
Seller if there is any material breach of any representation, warranty, covenant or agreement on the part of Buyer set forth in this
Agreement, such that the conditions specified in Section 8.01 or Section 8.03 would not be satisfied at the Closing (a
 “Terminating Buyer Breach”), except that, if any such Terminating Buyer Breach is curable by Buyer, then, for a
period of up to 30 days after receipt by Buyer of notice from Seller of such breach (the “Buyer Cure
Period”) such termination shall not be effective and the End Date shall automatically be revised to be the later of the
original End Date and the first Business Day following the end of the Buyer Cure Period, and such termination shall become effective
only if the Terminating Buyer Breach is not cured within the Buyer Cure Period; or

 

(vi)            
by Seller if (A) the Marketing Period has ended and all of the conditions set forth in Section 8.01 and Section
8.02 have been satisfied (other than (1) those conditions which by their terms or nature are to be satisfied at the Closing and
(2) those conditions the failure of which to be satisfied is caused by or results from a breach by Buyer of this Agreement) as of
the date the Closing should have occurred pursuant to Section 2.03, (B) Buyer has failed to consummate the transactions contemplated
by this Agreement on or prior to the date on which the Closing should have occurred pursuant to Section 2.03, (C) following such
failure to consummate the transactions contemplated by this Agreement, Seller has confirmed in writing to Buyer that all of the conditions
set forth in Article 8 have been satisfied (other than conditions that, by their nature, are to be satisfied by actions taken at
the Closing and which were, as of the date the Closing should have occurred pursuant to Section 2.03, capable of being satisfied)
or that it is willing to waive any unsatisfied conditions to its obligation to the Closing as set forth in Article 8 and is prepared
to proceed with Closing and (D) Buyer fails to consummate the Closing within five Business Days after the delivery of such notice.

 

(b)

the other Party.

 

Section 10.02 Effect of Termination.

 

(a)              
If this Agreement is terminated as permitted by Section 10.01, such termination shall be without liability of any Party
(or any Representative of such Party) to the other Party; provided, however, that if such termination shall result from
the willful (i) failure to fulfill a condition to the performance of the obligations of the other Party set forth in Article 8
or (ii) failure to perform a covenant of such Party set forth in this Agreement, which act or failure to act constitutes in and of itself
a material breach of this Agreement (each, a “Willful Breach”), such Party shall, except as otherwise provided in this
Section 10.02, be fully liable for any and all Damages incurred or suffered by the other Party as a result of such Willful Breach;
provided, further, that Seller’s liability for Damages incurred or suffered by Buyer as a result of any Willful Breach
shall not exceed $32,000,000. The provisions of Article 1, Section 5.12(e), this Section 10.02 and Article 11
shall survive any termination of this Agreement and, for the avoidance of doubt, the Mutual Confidentiality Agreement shall continue to
survive in accordance with its terms.

 

    84

 Notwithstanding anything to the contrary in this Agreement, in the event that (i) this Agreement has been terminated by either
Seller or Buyer pursuant to Section 10.01(a)(ii) or Section 10.01(a)(iii) (in the case of any Order or other action enjoining,
prohibiting or rendering illegal the consummation of the transactions contemplated hereby brought by a Governmental Authority in respect
of or under any applicable requirements of the ICCTA or the regulations of the STB (each, a “Regulatory Restraint”))
or by Seller pursuant to Section 10.01(a)(v) as a result of a material breach by Buyer of Section 5.03 (with respect to
obtaining STB Approval), (ii) the conditions set forth in Section 8.01(a), Section 8.01(b) (in the case of any Regulatory
Restraint) or Section 8.02(d) have not been satisfied or waived as of the date of such termination, (iii) the Seller Fundamental

Seller Fundamental Warranties and the representation and warranty contained in Section 3.09(b), contained in this Agreement (disregarding
all qualifications contained therein relating to materiality or Material Adverse Effect) were true and correct as of the date of this
Agreement, except with respect to representations and warranties that speak as to an earlier date, which representations and warranties
shall be true and correct at and as of such date, except, in each case, for any inaccuracy or omission that would not reasonably be expected
to, individually or in the aggregate, have a Material Adverse Effect, (v) there has not been a Willful Breach by Seller, and (vi) Seller
has complied in all material respects with its applicable obligations under Section 5.03 (a “Regulatory Failure Termination”),
then concurrently with such termination (in the case of a termination by Buyer) or no later than three Business Days following such termination
(in the case of a termination by Seller), Buyer shall pay to Seller a fee equal to $32,000,000 (the “Regulatory Termination Fee”)
by wire transfer of immediately available funds to a bank account provided to Buyer by Seller. Other than in connection with a Willful
Breach by Buyer, the payment of the Regulatory Termination Fee by Buyer pursuant to this Section 10.02(b) shall be deemed to be
liquidated damages for any and all Damages suffered or incurred by the Seller and its Affiliates in connection with a Regulatory Failure
Termination and Seller’s right to terminate this Agreement and receive payment of the Regulatory Termination Fee pursuant to this
Section 10.02(b) will be the sole and exclusive remedy of Seller and its Affiliates against Buyer for the failure of the Closing
to be consummated by reason of a Regulatory Failure Termination.

 

(c)               Notwithstanding
anything to the contrary contained herein, in the event that (i) all of the conditions set forth in Article 8 have been
satisfied or waived (other than any such conditions which by their nature cannot be satisfied until the Closing Date, but subject to
such conditions being capable of being satisfied if the Closing Date were the date of termination); (ii) Seller has notified Buyer
that all of the conditions set forth in Section 8.01 and Section 8.02 have been
satisfied or waived (other than those conditions that by their nature cannot be satisfied other than at the Closing and those
conditions that are not satisfied as a result of Buyer’s breach), (iii) Buyer fails to consummate the Closing on the date the
Closing should have occurred pursuant to Section 2.03, solely due to the fact that the Debt Financing (or, if Alternative
Financing is being used in accordance with Section 5.12, pursuant to the commitments with respect thereto) is not available
to Buyer, (iv) Seller has complied in all material respects with all of its covenants in this Agreement,
and (v) this Agreement is terminated by Seller pursuant to Section 10.01(a)(vi) (a “Financing Failure
Termination”), then no later than three Business Days following such termination, Buyer shall pay to Seller a fee
equal to $32,000,000 (the “Financing Termination Fee”) by wire transfer of immediately available funds to a bank
account provided to Buyer by Seller. The payment of the Financing Termination Fee by Buyer pursuant to this Section 10.02(c)
shall be deemed to be liquidated damages for any and all Damages suffered or incurred by the Seller and its Affiliates in connection
with a Financing Failure Termination and Seller’s right to terminate this Agreement and receive payment of the Financing
Termination Fee pursuant to this Section 10.02(c) will be the sole and exclusive remedy of Seller and its Affiliates against
Buyer for the failure of the Closing to be consummated by reason of a Financing Failure Termination, including if such Financing
Failure Termination is considered to be Willful Breach by Buyer.

Section 11.02 Seller Disclosure
Schedule. The Seller Disclosure Schedule is incorporated in and made a part of this Agreement as if set forth in full herein. Disclosure
of any item on the Seller Disclosure Schedule shall not constitute an admission or indication that such item or matter is material or
would constitute a Material Adverse Effect, is outside the ordinary course of business or is required to be disclosed. No disclosure
on the Seller Disclosure Schedule relating to a possible breach or violation of any Contract, Law or Order shall be construed as an admission
or indication that any breach or violation exists or has actually occurred. Nothing contained in the Seller Disclosure Schedule should
be construed as an admission of liability or responsibility of any Party to any third party in connection with any pending or threatened
Legal Proceeding or otherwise. Any disclosure, exception, qualification, limitation, document or other item described in any exhibit,
schedule, provision, sub-provision, Section or subsection of the Seller Disclosure Schedule with respect to a particular representation
or warranty contained in this Agreement shall be deemed to be an exception or qualification with respect to all other representations
and warranties contained in this Agreement to the extent that it is reasonably apparent on its face that such disclosure, exception,
qualification, limitation, document or other item is applicable to such other representations and warranties. Except as otherwise expressly
set forth in any Section or subsection of the Seller Disclosure Schedule, in no event will the listing or disclosure of any
information or document in any Section or subsection of the Seller Disclosure Schedule or in the documents referred to or incorporated
by reference in any such Section or subsection of the Seller Disclosure Schedule constitute or be deemed to imply any representation,
warranty, undertaking, covenant or other obligation of Seller not expressly set out in this Agreement or will such disclosure be construed
as extending the scope of any representation or warranty, undertaking, covenant or obligation set out in this Agreement. Where brief
particulars of a matter are set out or referred to in the Seller Disclosure Schedule, or a document is referred to but not attached,
or a reference is made to a particular part only of such a document, full particulars of the matter and full contents of the document
are deemed to be disclosed as if set out in full in the Seller Disclosure Schedule, and the reference to the document in the Seller Disclosure
Schedule shall be deemed to incorporate by reference all terms and conditions of, and amendments, purchase orders, schedules and annexes
to, such document, provided that such documents, amendments, purchase orders, schedules and annexes, as applicable, were made available
to Buyer prior to the date of this Agreement. The information about Contracts or documents listed in the Seller Disclosure Schedule is
for identification purposes and is not intended to summarize the terms of such Contracts or documents. Where the terms and conditions
of a Contract or document are referenced, summarized or described in the Seller Disclosure Schedule, such reference, summary or description
does not purport to be a complete statement of the terms or conditions of such Contract or document and such reference, summary or description
is qualified in its entirety by the specific terms and conditions of such Contract or document, provided that a copy of such Contract
or document was made available to Buyer prior to the date of this Agreement.

 

    87

     

    

 

Section 11.03 Successors and Assigns. The
provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns;
provided that no Party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without
the consent of the other Parties.

 

Section 11.04 Entire Agreement. This Agreement
constitutes the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements and
understandings, both oral and written, between the Parties with respect to the subject matter hereof. Without limiting the foregoing,
it is the intent of the Parties that Article 9 constitutes a comprehensive listing of the conditions of the Parties to their obligations
hereunder. Each Party waives any right to assert any theory of “force majeure,” “frustration of purpose,” “impracticability,”
 “impossibility” or other theory under Applicable Law that would have the effect of excusing any Party from its obligations
to perform hereunder or that would otherwise have the effect of terminating or suspending this Agreement or delaying or preventing the
performance of the transactions contemplated hereby.

 

Section 11.05 Amendment and Waiver.

 

(a)              
Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed,
in the case of an amendment, by Buyer and Seller, or in the case of a waiver, by the Party against whom the waiver is to be effective.

 

(b)              
No failure or delay by any Party in exercising any right, power or privilege hereunder shall impair such right or remedy or operate
or be construed as a waiver or variation thereof or preclude its exercise at any subsequent time nor shall any single or partial exercise
of any such right, power or privilege preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

 

(c)              
Except as set forth in Section 9.10, the rights and remedies herein provided shall be cumulative and not exclusive of any
rights or remedies provided by Law.

 

(d)              
Notwithstanding anything to the contrary contained in this Agreement, Section 4.05 (Financing Capacity), Section
5.12 (Financing), Section 9.09 (Debt Financing Source Liability), this Section 11.05(d) (Amendment
and Waiver), Section 11.08 (Third Party Rights), Section 11.11(c) (Dispute Resolution), Section 11.12
(Governing Law) and Section 11.14 (Waiver of Jury Trial) and the definitions of “Debt Financing Sources”
and “Debt Financing Related Parties” (or any other provision or definition of this Agreement to the extent that such amendment
or waiver would modify the substance of any of the foregoing Sections) may not be amended, modified, supplemented or waived in a manner
that is materially adverse to the Debt Financing Sources without the prior written consent of the Debt Financing Sources.

 

Section 11.06 Costs.
Except as otherwise expressly provided herein (including Section 5.03 and Section 5.12(f)), all costs and expenses incurred
in connection with this Agreement shall be paid by the Party (including its Affiliates) incurring such cost or expense.

 

    88

     

    

 

Section 11.07 Severability. Each term, provision,
covenant and restriction of this Agreement is severable. If any such term, provision, covenant or restriction is held by a court of competent
jurisdiction to be invalid, void or unenforceable, (a) it shall have no effect in that respect and the Parties shall use all reasonable
efforts to replace it in that respect with a valid and enforceable substitute term, provision, covenant or restriction (as applicable),
the effect of which is as close to its intended effect as possible; and (b) the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long
as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party.

 

Section 11.08 Third Party Rights. Except
for Section 5.10, Section 9.02, Section 11.03 and the last sentence of this Section 11.08, no provision of
this Agreement is intended to confer any rights, benefits, remedies, obligations, or liabilities hereunder upon any Person, other than
the Parties and their respective successors and assigns. Notwithstanding the foregoing, the Debt Financing Sources shall be express third
party beneficiaries of Section 9.09, Section 11.05, this Section 11.08, Section 11.11(c), Section 11.12
and Section 11.14, and each of such Sections shall expressly inure to the benefit of the Debt Financing Sources and the Debt Financing
Related Parties, and the Debt Financing Sources and the Debt Financing Related Parties shall be entitled to rely on and enforce the provisions
of such Sections.

 

Section 11.09 Waiver of Conflicts Regarding
Representation; Nonassertion of Attorney-Client Privilege.

 

(a)              
It is acknowledged by each of the Parties, on behalf of itself and its directors, members, partners, officers, employees and Affiliates,
and each of their successors and assigns (all such parties, the “Waiving Parties”), that Seller retained Jones Day
and Baker and Miller PLLC to act as their legal counsel in connection with the transactions contemplated hereby. Each Party hereby agrees
that, in the event of any Dispute arising after the Closing relating to the negotiation, preparation, execution and delivery of this Agreement,
the Transaction Agreements and the consummation of the transactions contemplated hereby and thereby (the “Current Representation”),
Jones Day or Baker and Miller PLLC may represent Seller and its Affiliates and Subsidiaries (including their direct and indirect equityholders)
(collectively, the “Seller Entities”) in such Dispute, even though the interests of the Seller Entities may be directly
adverse to Buyer, the Company Group members or any of their respective Affiliates, and even though Jones Day and Baker and Miller PLLC
may formerly have represented Buyer, the Company Group members or any of their respective Affiliates in a matter substantially related
to such Dispute, or may be handling ongoing matters for Buyer, the Company Group members or any of their respective Affiliates. Buyer,
on behalf of itself and its other Waiving Parties (including the Company Group following the Closing), hereby consents to and waives (and
will not assert) any conflict of interest or any claim or objection arising therefrom or relating thereto.

 

    89

     

    

 

(b)              
Buyer further agrees that all communications among Jones Day, Baker and Miller PLLC, Seller, the Company Group members, any of
their respective Affiliates and Subsidiaries and the other Seller Entities that relate in any way to the Representation (including all
of the client files and records in the possession of Jones Day or Baker and Miller PLLC related thereto) constitute attorney-client privileged
communications between the Seller Entities and Jones Day or Baker and Miller PLLC, as applicable, and the attorney-client privilege and
the expectation of client confidence belongs to the Seller Entities and may be controlled by the Seller Entities and will not pass to
or be claimed by Buyer or any of its Affiliates (including the Company Group members following the Closing and, in connection therewith,
the Company Group members are transferring any rights in respect thereof to Seller). From and after the Closing, Buyer, on behalf of
itself and its other Waiving Parties (including the Company Group members following the Closing), waives and will not assert any attorney-client
privilege with respect to any communication among Jones Day, Baker and Miller PLLC, Seller, the Company Group members, any of their respective
Affiliates and Subsidiaries and the other Seller Entities occurring in connection with the Representation. Notwithstanding the foregoing,
if a Dispute arises between Buyer or any Company Group member, on the one hand, and a third party, on the other hand, Buyer or such Company
Group member may assert confidentiality protection or the attorney-client privilege with respect to all such communications to prevent
the disclosure thereof; provided that Buyer or such Company Group member may not waive such privilege without the prior written
consent of Seller. None of Buyer, the Company Group members or any of Buyer’s other Waiving Parties, or any Person purporting to
act on behalf of or through Buyer, any Company Group member or any of Buyer’s other Waiving Parties, will access or seek to obtain
access to any such communications, or to the files of Jones Day or Baker and Miller PLLC relating to the Current Representation. Neither
Jones Day nor Baker and Miller PLLC will have any duty whatsoever to reveal or disclose any such attorney-client communications or files
to any of Buyer, the Company Group members or any of Buyer’s other Waiving Parties by reason of any attorney-client relationship
between Jones Day or Baker and Miller PLLC, on the one hand, and the Company Group members, on the other hand, or otherwise. In addition,
Buyer agrees that it would be impractical to remove all attorney-client communications from the records (including e-mails and other
electronic files) of the Company Group members. Accordingly, as to any such communications prior to the date hereof, Buyer, on behalf
of itself and its other Waiving Parties (including the Company Group members following the Closing), further agrees that no such Person
may use, rely on or access without the prior written consent of Seller any of such communications in a manner that may compromise the
attorney-client privilege of such communications or otherwise be adverse to Seller or any of its Affiliates.

 

Section 11.10 Counterparts; Effectiveness.
This Agreement may be signed in any number of counterparts, and by each Party on separate counterparts. Each such counterpart shall be
an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective
when each Party shall have received a counterpart hereof signed by the other Parties. Until and unless each Party has received a counterpart
hereof signed by the other Parties, this Agreement shall have no effect and no Party shall have any right or obligation hereunder (whether
by virtue of any other oral or written agreement or other communication). Delivery of a counterpart hereof by email attachment shall be
an effective mode of delivery.

Section 11.11 Dispute Resolution.

 

(a)              
General Provisions. The Parties shall use Commercially Reasonable Efforts to settle amicably any and all disputes, controversies
or claims (whether sounding in contract, tort, common law, statutory law, equity or otherwise) arising out of or relating to this Agreement,
including any question regarding its existence or scope, the meaning of its provisions, or the proper performance of any of its terms
by either Party, or its breach, termination or invalidity (each such dispute, controversy or claim, a “Dispute”). Except
as otherwise expressly provided herein (including the procedures set forth in Section 2.06(c) which will be the sole dispute resolution
procedure respect to the Final Closing Statement), any Dispute shall be resolved in accordance with the procedures set forth in this Section
11.11.

 

(b)              
Resolution by Senior Executives. If a Dispute cannot be resolved at an operational level, either Party may give written
notice to the other Party, requesting that senior management or senior representatives of each Party attempt to resolve the Dispute. Within
15 Business Days after the request, the other Party shall provide a written response. The notice and the response shall designate such
Party’s senior executive and provide a statement of the Party’s position and a summary of reasons supporting that position.
The designated senior executives or representatives shall meet in person at a mutually acceptable place, or by telephone, within 10 Business
Days after receiving the response to seek a resolution. If no resolution is reached by the expiration of 30 calendar days from the date
of the notice of Dispute, either Party may submit the Dispute to resolution as further provided herein.

 

(c)              
Arbitration; Jurisdiction.

 

(i)                
If the Parties are unable to reach a resolution pursuant to Section 11.11(b), the Parties may submit the Dispute for resolution
by binding arbitration under the administration of the American Arbitration Association (“AAA”) in accordance with
its Rules for Arbitration in effect at the time of the arbitration, subject to such modifications set forth in this Agreement.

 

(ii)               
In any Dispute, the arbitral tribunal shall be composed of three arbitrators, selected as follows: (A) each Party shall designate
one arbitrator within 20 calendar days after the request for arbitration is filed; (B) the first two arbitrators shall select the third
arbitrator within 30 calendar days after the last of the first two arbitrators has been nominated, and shall not be affiliated with either
Party; and (C) in the event that the initial two arbitrators fail to agree to a third arbitrator, the third arbitrator shall be chosen
by the AAA. The arbitration proceedings shall be conducted in the English language. The arbitration shall be conducted in Pittsburgh,
Pennsylvania, which shall be the seat of the arbitration. Each Party shall be permitted to present its case, witnesses and evidence, if
any, in the presence of the other Party. Either Party can request a written transcript of the proceedings at that Party’s cost.
The arbitral tribunal shall determine the Dispute consistent with the substantive law described in Section 11.13, and shall apply
this Agreement according to its terms.

 

    91

     

    

 

(iii)               
 The Parties agree that any Disputes resolved pursuant to this Section 11.11 are commercial in nature. The Parties agree
to be bound by any award or order resulting from arbitration conducted hereunder notwithstanding any country’s laws or treaties
with the United States to the contrary. The Parties agree that in the context of an attempt by either Party to enforce an arbitral award
or order, any defenses relating to any other Parties’ capacity or the validity of this Agreement or any related agreement under
any Law are waived. Any judgment on an award or order resulting from an arbitration conducted under this Section 11.11 may be entered
and enforced in any court, in any country, having jurisdiction over either Party or their assets. For the purposes of enforcement of an
award or order as described in the preceding sentence, the Parties submit to the non-exclusive jurisdiction of the state and federal courts
of Delaware and Pennsylvania.

 

(iv)               
Each Party shall bear its own fees and expenses, including fees and expenses of financial and legal advisors and other outside
consultants, in connection with any arbitration conducted under this Section 11.11.

 

(v)               
Notwithstanding anything in this Agreement to the contrary, each of the Parties hereto agrees that it will not bring or support
(or permit any of their controlled Affiliates to bring or support) any claim or cause of action (whether in contract, tort or otherwise),
against any Debt Financing Source or any Debt Financing Related Party in any way relating to this Agreement or any of the transactions
contemplated by this Agreement, including any dispute arising out of or relating in any way to the Debt Commitment Letter, the Debt Financing
or the Definitive Agreements executed in connection therewith or the performance thereof or services provided thereunder, in any forum
other than any federal court in the Borough of Manhattan, New York, New York and any appellate court thereof, and each Party waives any
objection which such Party may now or hereafter have to the laying of the venue of any such action, suit or proceeding, and irrevocably
submits to the jurisdiction of any such court in any such action, suit or proceeding.

 

(d)              
Admissibility into Evidence. All offers of compromise or settlement between the Parties or their Representatives in connection
with the attempted resolution of any Dispute (i) shall be deemed to have been delivered in furtherance of a Dispute settlement, (ii) shall
be exempt from discovery and production and (iii) shall not be admissible into evidence (whether as an admission or otherwise) in any
proceeding for the resolution of the Dispute.

 

(e)              
Proceedings Confidential. Except to the extent necessary to enforce any arbitral award, to enforce other rights of the
Parties, or as required by Applicable Law or the applicable rules of any stock exchange, each Party shall ensure that it and its Affiliates,
and all of their respective Representatives and expert witnesses, shall maintain as confidential the existence of the arbitration proceedings,
the arbitral award, all filings and submissions exchanged or produced during the arbitration proceedings and briefs, memorials, witness
statements or other documents prepared in connection with such arbitration; provided, however, that a Party may disclose
such information to its Affiliates and all of its and its Affiliates’ respective Representatives and expert witnesses; it being
understood that such Affiliates and Representatives will be informed of the confidential nature of the existence of any such arbitration
proceedings, arbitral award, filings and submissions, briefs, memorials, witness statements and other documents and will be directed
to treat the foregoing as confidential in accordance with the terms of this Agreement and each Party will be responsible for the compliance
by its Affiliates and its and their respective Representatives and expert witnesses with this Section 11.11(e). This Section
11.11(e) shall survive the termination of the arbitral proceedings.

 

    92

     

    

 

(f)               
Privilege. Legal professional privilege, including privileges protecting attorney-client communications and attorney work
product of each Party from disclosure or use in evidence, as recognized by Applicable Laws governing each Party’s relationship with
its counsel, including in-house counsel, shall apply to and be binding in any arbitration proceeding under this Section 11.11(f).

 

Section 11.12 Governing Law. This Agreement
shall be governed by and construed in accordance with the Law of the State of Delaware, without regard to the conflicts of Law rules of
such state; provided, however, that notwithstanding anything in this Agreement to the contrary, all claims or causes of
action (whether at law, in equity, in contract, in tort or otherwise) against any Debt Financing Source in any way relating to this Agreement
and any right or obligation with respect to any Debt Financing Source in connection with the Debt Financing or the Debt Commitment Letter
shall be construed and interpreted in accordance with the Laws of the State of New York, without giving effect to any conflicts of law
principles (whether of the State of New York or any other jurisdiction) that would cause the application of the Laws of any jurisdiction
other than the State of New York.

 

Section 11.13 Specific Performance. The
Parties agree that irreparable damage would occur, and that the Parties would not have any adequate remedy at Law, 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, except in the event of (x) a Regulatory Failure Termination and the payment of the Regulatory Termination Fee pursuant to
Section 10.02(b) and (y) a Financing Failure Termination and the payment of the Financing Termination Fee pursuant to Section
10.02(c), the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to specifically
enforce the terms and provisions of this Agreement, without proof of actual damages or otherwise, in addition to any other remedy to which
any Party is entitled at Law or in equity. Each Party agrees to waive any requirement for the securing or posting of any bond in connection
with such remedy. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to
Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy. To the extent any
Party brings a Legal Proceeding to enforce specifically the performance of the terms and provisions of this Agreement (other than an action
to enforce specifically any provision that expressly survives termination of this Agreement), the End Date shall automatically be extended
to (a) the 20th Business Day following the resolution of such Legal Proceeding or (b) such other time period established
by the court presiding over such Legal Proceeding.

 

    93

     

    

 

Section 11.14 Waiver of Jury Trial. EACH
OF THE PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS
AGREEMENT, THE DEBT COMMITMENT LETTER OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY OR THE PERFORMANCE OF ANY SERVICES THEREUNDER
OR THE TRANSACTIONS CONTEMPLATED HEREBY.
