	6.	Covenants. 

  
 6.1 Access to Information. Before Closing, Seller shall permit, and shall use its commercially reasonable efforts to cause Vesco Holdings and VESCO
to permit, Purchaser and its representatives (including its legal advisors and accountants) to have reasonable access, during normal business hours and upon reasonable advance notice, to the properties, books, records and personnel of VESCO;
provided, that in no event shall Seller, Vesco Holdings or VESCO be obligated to provide (i) access or information in violation of applicable Law or VESCO’s LLC Agreement, (ii) bids, letters of intent, expressions of interest, or other
proposals received from others in connection with the transactions contemplated by this Agreement or otherwise and information and analyses relating to such communications, (iii) any information, the disclosure of which would jeopardize any
privilege available to Seller, Vesco Holdings, VESCO or any of their respective Affiliates relating to such information or would cause Seller, Vesco Holdings, VESCO or any of their respective Affiliates to breach a confidentiality obligation by
which it is bound or (iv) any of Seller’s or Vesco Holding’s internal valuations of the industry of VESCO, Vesco Holdings, VESCO or the VESCO Membership Interest. Purchaser’s access to the properties, books, records and personnel of
VESCO shall be subject to applicable third party manager/operator approvals. In connection with such access, Purchaser’s representatives shall cooperate with Seller’s, Vesco Holding’s and 
  

 11 








 VESCO’s representatives and shall use their commercially reasonable efforts to minimize any disruption of the
business of Seller, Vesco Holdings, VESCO and the manager/operator of the assets of VESCO, as the case may be. Purchaser agrees to abide by any safety rules or rules of conduct reasonably imposed by Seller, Vesco Holdings, VESCO or the
manager/operator of the assets of VESCO, as the case may be, with respect to Purchaser’s access and any information furnished to Purchaser or its representatives pursuant to this Section 6.1. Purchaser shall indemnify, defend and hold
harmless Seller, Vesco Holdings and VESCO and their respective officers, directors, employees and agents from and against any and all Losses asserted against or suffered by them relating to, resulting from, or arising out of, examinations or
inspections made by Purchaser or its representatives pursuant to this Section 6.1, except to the extent such Losses relate to, result from or arise out of, the gross negligence or willful misconduct of Seller. Notwithstanding anything to the
contrary contained herein, before Closing, without the prior written consent of Seller, which may be withheld for any reason, (i) Purchaser shall not contact any suppliers to, or customers of, VESCO or its Affiliates and (ii) Purchaser shall have no
right to perform invasive or subsurface investigations of the properties or facilities of VESCO. 
  
 6.2 Further Assurances. Upon the terms and subject to the conditions contained herein, the Parties agree: (a) to use all commercially reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement, (b) to execute any documents, instruments
or conveyances of any kind which may be reasonably necessary or advisable to carry out any of the transactions contemplated hereunder or thereunder, and (c) to reasonably cooperate with each other in connection with the foregoing. 
  
 6.3 Supplementation and Amendment of Schedules. From time to time
before the Closing, Seller shall have the right to supplement or amend the Schedules with respect to any matter hereafter arising or discovered after the delivery of the Schedules pursuant to this Agreement. No such supplement or amendment shall
have any effect on the satisfaction of the condition to closing set forth in Section 8.2(a); provided, however, if the Closing shall occur, then Purchaser shall be deemed to have waived any right or claim pursuant to the terms of this
Agreement or otherwise, including pursuant to Article 7 hereof, with respect to any and all matters disclosed pursuant to any such supplement or amendment at or before the Closing. 
  
 6.4 Antitrust Approvals. 
  
 (a) Each of Purchaser and Seller shall, and Seller shall cause Vesco Holdings to, (i) make or cause to be made all filings required of each of them or any
of their respective Affiliates under the Antitrust Laws with respect to the transactions contemplated hereby as promptly as practicable and, in any event, within fifteen (15) Business Days after the date of this Agreement, (ii) comply at the
earliest practicable date 
  

 12 








 with any request under the HSR Act or other Antitrust Laws for additional information, documents, or other materials
received by each of them or any of their respective subsidiaries from the Federal Trade Commission (the “FTC”), the Antitrust Division of the U.S. Department of Justice (the “Antitrust Division”) or any other
Governmental Body in respect of such filings or such transactions, and (iii) cooperate with each other in connection with any such filing (including, to the extent permitted by applicable Law, responding to any reasonable requests for copies of all
such documents to the non-filing parties before filing and considering all reasonable additions, deletions or changes suggested in connection therewith) and in connection with resolving any investigation or other inquiry of any of the FTC, the
Antitrust Division or other Governmental Body under any Antitrust Laws with respect to any such filing or any such transaction. Each such party shall use its best efforts to furnish to each other all information required for any application or other
filing to be made pursuant to any applicable Law in connection with the transactions contemplated by this Agreement. Any party may, as it deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other
parties under this Section 6.4 as “outside counsel only.” Such materials and the information contained therein shall be given only to the outside legal counsel of the recipient, and the recipient shall cause such outside counsel not
to disclose such materials or information to any employees, officers, directors or other representatives of the recipient or their Affiliates, unless express written permission is obtained in advance from the source of the materials. Each such party
shall promptly inform the other party hereto of any oral communication with, and provide copies of written communications with, any Governmental Body regarding any such filings or any such transaction. No party hereto shall independently participate
in any formal meeting with any Governmental Body in respect of any such filings, investigation, or other inquiry without giving the other party hereto prior notice of the meeting and, to the extent permitted by such Governmental Body, the
opportunity to attend and/or participate. Subject to applicable Law, the parties hereto will consult and cooperate with one another in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals
made or submitted by or on behalf of any party hereto relating to proceedings under the HSR Act or other Antitrust Laws. Purchaser shall pay all filing fees in connection with all filings under the Antitrust Laws. 
  
 (b) Each of Purchaser and Seller shall, and Seller shall cause Vesco Holdings
to, use its best efforts to resolve such objections, if any, as may be asserted by any Governmental Body with respect to the transactions contemplated by this Agreement under the Antitrust Laws. In connection therewith, if any Legal Proceeding is
instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as in violation of any Antitrust Law, each of Purchaser and Seller shall, and Seller shall cause Vesco Holdings to, cooperate and use its best
efforts to contest and resist any such Legal Proceeding, and to have vacated, lifted, reversed, or overturned any decree, judgment, injunction or other order whether temporary, preliminary or permanent, that is in effect and that prohibits,
prevents, limits or restricts consummation of the transactions contemplated by this Agreement, including by pursuing all available avenues 
  

 13 








 of administrative and judicial appeal and all available legislative action, unless, by mutual agreement, Purchaser and
Seller decide that litigation is not in their respective best interests. Each of Purchaser and Seller shall, and Seller shall cause Vesco Holdings to, use its best efforts to take such action as may be required to cause the expiration of the notice
periods under the HSR Act or other Antitrust Laws with respect to such transactions as promptly as possible after the execution of this Agreement. In connection with and without limiting the foregoing, Purchaser agrees to take promptly any and all
steps necessary to avoid or eliminate each and every impediment under any Antitrust Laws that may be asserted by any Federal, state and local and non-United States antitrust or competition authority, so as to enable the parties to close the
transactions contemplated by this Agreement as expeditiously as possible, including committing to or effecting, by consent decree, hold separate orders, trust or otherwise, the sale or disposition of such of its assets or businesses (including any
acquired pursuant to this Agreement) as are required to be divested in order to avoid the entry of, or to effect the dissolution of, any decree, order, judgment, injunction, temporary restraining order or other order in any suit or preceding, that
would otherwise have the effect of preventing, delaying or limiting the consummation of the transactions contemplated by this Agreement. 
  
 6.5 Use of Name. Purchaser agrees that (i) neither Purchaser nor any of its Affiliates has any right, title or interest in or to the name
“Koch” or any service marks, trademarks, trade names, identifying symbols, logos, emblems, signs or insignia related thereto or containing or comprising the foregoing, including any derivations, modifications or alterations thereof, and
any word, name or mark confusingly similar thereto (collectively, the “Koch Marks”), (ii) neither Purchaser nor any of its Affiliates shall have any right to use the Koch Marks after the Closing Date and (iii) Purchaser shall
immediately after the Closing change the name of Vesco Holdings to any name other than the Koch Marks and Purchaser shall, and Purchaser shall cause its Affiliates to, otherwise cease to hold itself out as having any affiliation with Seller or any
of its Affiliates. In furtherance thereof, as promptly as practicable but in no event later than one hundred twenty (120) days following the Closing Date, Purchaser shall remove, strike over or otherwise obliterate all Koch Marks from all materials
including any vehicles, business cards, schedules, stationery, packaging materials, displays, signs, promotional materials, manuals, forms, computer software and other materials. 
  
 6.6 Preservation of Records. Purchaser shall cause Vesco Holdings to preserve and keep the records relating to VESCO
and Vesco Holdings for a period of seven (7) years from the Closing Date, or, if longer, as required by Law. Purchaser shall cause Vesco Holdings to make such records and personnel available as may be reasonably required by Seller in connection
with, among other things, any insurance claims or indemnification claims by, Legal Proceedings or tax audits against or governmental investigations of Seller or any of its Affiliates or in order to enable Seller to comply with its obligations under
this Agreement and each other agreement, document or instrument contemplated hereby or thereby. In the event Purchaser wishes to destroy such records after that time, Purchaser shall cause Vesco Holdings first to give ninety 
  

 14 








 (90) days prior written notice to Seller, and Seller shall have the right at its option and expense, upon prior written
notice given to Purchaser within that ninety (90) day period, to take possession of the records within one hundred and eighty (180) days after the date of such notice. 
  
 6.7 Publicity. 
  
 (a) Neither Purchaser nor Seller shall, and Seller shall cause Vesco Holdings not to, issue any press release or public announcement concerning this
Agreement or the transactions contemplated hereby without obtaining the prior written approval of the other party hereto, which approval will not be unreasonably withheld, conditioned or delayed, unless, in the reasonable judgment of Seller or
Purchaser, disclosure is otherwise required by applicable Law, provided that, to the extent required by applicable Law, the party intending to make such release shall use its commercially reasonable efforts consistent with applicable Law to consult
with the other party with respect to the text thereof. 
  
 (b)
Each of Purchaser and Seller agree that the terms of this Agreement shall not be disclosed or otherwise made available to the public and that copies of this Agreement shall not be publicly filed or otherwise made available to the public, except
where such disclosure, availability or filing is required by applicable Law and only to the extent required by such Law. In the event that such disclosure, availability or filing is required by applicable Law, each of Purchaser and Seller, as
applicable, agrees to use its commercially reasonable efforts to obtain “confidential treatment” of this Agreement with the U.S. Securities and Exchange Commission (or the equivalent treatment by any other Governmental Body) and to redact
such terms of this Agreement as the other party may request. 
  
 6.8 Tax Matters. 
  
 (a) Tax Allocation.
If VESCO shall have an election in effect under Section 754 of the Code for the taxable year of VESCO that includes the Closing Date, then as promptly as practicable, but in no event later than sixty (60) days after the Closing Date, Purchaser shall
prepare and deliver to Seller a statement (the “Valuation Statement”) valuing the assets of VESCO for purposes of (i) Treasury Regulation Section 1.743-1(d)(2) in determining Purchaser’s adjustment to the federal income tax
basis of the assets of VESCO and for purposes of performing Purchaser’s obligations pursuant to section 3 of Exhibit F to the VESCO LLC Agreement, and (ii) Treasury Regulation Section 1.751-1(a)(2) in determining the character of Seller’s
gain or loss, as the case may be, for federal income tax purposes in respect of the transactions contemplated by this Agreement. Seller shall have fifteen (15) days to review the Valuation Statement and shall notify Purchaser of any disputes with
the valuation as set forth in the Valuation Statement. Seller and Purchaser shall negotiate in good faith to resolve any such dispute before the date that is sixty (60) days before the due date of the tax returns that reflect the valuation. If
Seller and Purchaser cannot resolve the disputed 
  

 15 








 valuation before such date, then Seller and Purchaser shall refer the dispute to PricewaterhouseCoopers LLP (the
“Accounting Referee”) to review and to determine the proper valuation (it being understood that in making such determination, the Accounting Referee shall be functioning as an expert and not as an arbitrator). The Accounting Referee
shall deliver to Seller and Purchaser, as promptly as practicable (but in any case no later than thirty (30) days from the date of engagement of the Accounting Referee), a determination of the valuation. This determination will be binding on the
Parties and all tax returns filed by Purchaser, Seller and each of their Affiliates shall be prepared consistently with such valuation. The cost of such review and report shall be borne by Purchaser. Seller and Purchaser shall use commercially
reasonable efforts to ensure that the Valuation Statement is not disputed by VESCO. 
  
 (b) Tax Elections. Purchaser shall not make an election under Treasury Regulation Section 301.7701-3 (or any similar election under state or local Law) to treat Vesco Holdings as a corporation for tax purposes
for any period before the Closing. 
  
 (c) Interim Closing of
VESCO Books. Seller and Purchaser shall cooperate to request the Management Committee of VESCO to perform an interim closing of the books of VESCO as of the Closing Date pursuant to Treasury Regulation Section 1.706-1(c)(2)(ii). 
  
 6.9 Insurance. 
  
 (a) Purchaser shall not, and shall cause Vesco Holdings not to, assert any
right, claim or interest to or under any insurance policies or rights to proceeds thereof in effect on or before the Closing Date relating to Vesco Holdings, VESCO or Seller. In furtherance thereof, Purchaser, on behalf of itself and Vesco Holdings,
hereby waives any and all rights to or under any such insurance policies. 
  
 (b) Notwithstanding the foregoing Section 6.9(a), if between the date of this Agreement and the Closing, (i) any Loss or damage to the improvements or other tangible personal property of VESCO or Vesco Holdings
shall occur from fire, casualty or any other occurrence, (ii) Seller does not at its discretion replace or restore such property before the Closing Date and (iii) the Closing occurs, then all insurance proceeds received by Seller or Vesco Holdings
as a result of the event causing such loss or damage (net of any retrospective premium, payback or similar obligations in applicable insurance policies) will be delivered by Seller to Purchaser. For the avoidance of doubt, Seller shall not otherwise
have any obligation to replace or restore any such property if such insurance proceeds are assigned to Purchaser. Seller shall have the sole right and authority to provide notices and claims to the applicable insurance carrier and otherwise to
communicate and negotiate with such carrier, but shall use its commercially reasonable efforts to obtain any such proceeds payable to Seller. Notwithstanding the foregoing, the benefit of any insurance proceeds in relation to “business
interruption” damages based upon lost profits or business opportunities in respect of the period before the Closing 
  

 16 








 Date, and insurance proceeds in relation to such Loss or damage to the extent attributable to any such property replaced
or restored before the Closing Date or otherwise used for such purposes, will inure to the benefit of and be payable to Seller, and Purchaser will not be entitled to receive or retain such proceeds. 
  
 6.10 Confidentiality. Purchaser acknowledges that the information
provided to it in connection with this Agreement and the transactions contemplated hereby is subject to the terms of the confidentiality agreement between Purchaser and Seller dated April 27, 2005 (the “Confidentiality Agreement”),
the terms of which are incorporated herein by reference. Effective upon, and only upon, the Closing Date, the Confidentiality Agreement shall terminate. 
  

	7.	Indemnification. 

  
 7.1 Survival of Representations and Warranties and Covenants. All of the representations and warranties made by each Party in this Agreement shall
survive the consummation of the transactions contemplated herein and shall continue in full force and effect after the Closing for a period of nine (9) months; provided, however, that the representations and warranties made by Seller
in Sections 4.6 and 4.8 shall survive Closing until the fifth annual anniversary of the Closing Date. All of the covenants made by each Party in this Agreement shall survive the consummation of the transactions contemplated herein and
shall continue in full force and effect after the Closing indefinitely until all obligations with respect to any such covenants are fulfilled in their entirety. 
  

7.2 Indemnification by Seller. 
  
 (a) Subject to Sections 6.3, 7.1 and 7.5 hereof, Seller hereby agrees to indemnify and hold Purchaser and its directors, officers,
employees, Affiliates, stockholders, agents, attorneys, representatives and permitted assigns (collectively, the “Purchaser Indemnified Parties”) harmless from and against any Losses incurred by any of the Purchaser Indemnified
Parties based upon or arising directly from any breach of the representations, warranties, covenants or agreements made by Seller in this Agreement. 
  
 (b) Purchaser acknowledges and agrees that Seller shall not have any Liability under any provision of this Agreement for any Loss to the extent that such
Loss relates to action taken by Purchaser or any other Person (other than Seller in breach of this Agreement) after the Closing Date. Purchaser shall take and shall cause its Affiliates to take all reasonable steps to mitigate any Loss upon becoming
aware of any event that would reasonably be expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach that gives rise to the Loss. 
  

 17 








 7.3 Indemnification by Purchaser. 
  
 (a) Subject to Sections 7.1 and 7.5, Purchaser hereby agrees to indemnify and hold Seller and its directors,
officers, employees, Affiliates, stockholders, agents, attorneys, representatives and permitted assigns (collectively, the “Seller Indemnified Parties”) harmless from and against any Losses incurred by any of the Seller Indemnified
Parties based upon or arising directly from (i) any breach of the representations, warranties, covenants or agreements made by Purchaser in this Agreement or (ii) except as otherwise provided in Section 7.2(a), all Liabilities of any of VESCO
or Vesco Holdings arising on, before or after the Closing Date. 
  
 (b) Seller shall take and cause its Affiliates to take all reasonable steps to mitigate any Loss upon becoming aware of any event that would reasonably be expected to, or does, give rise thereto, including incurring costs only to the
minimum extent necessary to remedy the breach that gives rise to the Loss. 
  
 7.4 Indemnification Procedures. 
  
 (a) In the event that any Legal Proceedings shall be instituted, or that any claim shall be asserted, by any Person in respect of which payment may be sought under Sections 7.2 or 7.3 hereof ( an “Indemnification
Claim”), the indemnified party shall promptly cause written notice in reasonable detail of the assertion of any Indemnification Claim of which it has knowledge that is covered by this indemnity to be forwarded to the indemnifying party. The
indemnifying party shall have the right, at its sole option and expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the indemnified party, and to defend against, negotiate, settle or otherwise deal with any
Indemnification Claim that relates to any Losses indemnified against hereunder. If the indemnifying party elects to defend against, negotiate, settle or otherwise deal with any Indemnification Claim that relates to any Losses indemnified against
hereunder, it shall within ninety (90) days notify the indemnified party of its intent to do so. If the indemnifying party elects not to defend against, negotiate, settle or otherwise deal with any Indemnification Claim that relates to any Losses
indemnified against hereunder, the indemnified party may defend against, negotiate, settle or otherwise deal with such Indemnification Claim. If the indemnifying party shall assume the defense of any Indemnification Claim, the indemnified party may
participate, at its own expense, in the defense of such Indemnification Claim; provided, however, that such indemnified party shall be entitled to participate in any such defense with separate counsel at the expense of the indemnifying
party if, (i) so requested by the indemnifying party to participate or (ii) in the reasonable opinion of counsel to the indemnified party, a conflict or potential conflict exists between the indemnified party and the indemnifying party that would
make such separate representation advisable; and provided, further, that the indemnifying party shall not be required to pay for more than one such counsel for all indemnified parties in connection with any Indemnification Claim. The
parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or 
  

 18 








 settlement of any such Indemnification Claim. Notwithstanding anything in this Section 7.4 to the contrary,
neither the indemnifying party nor the indemnified party shall, without the written consent of the other party, settle or compromise any Indemnification Claim or permit a default or consent to entry of any judgment unless the claimant and such party
provide to such other party an unqualified release from all Liability in respect of the Indemnification Claim. Notwithstanding the foregoing, if a settlement offer solely for money damages is made by the applicable third party claimant, and the
indemnifying party notifies the indemnified party in writing of the indemnifying party’s willingness to accept the settlement offer and, subject to the applicable limitations of Section 7.5, pay the amount called for by such offer, and
the indemnified party declines to accept such offer, the indemnified party may continue to contest such Indemnification Claim, free of any participation by the indemnifying party, and the amount of any ultimate Liability with respect to such
Indemnification Claim that the indemnifying party has an obligation to pay hereunder, subject to the applicable limitations of Section 7.5, shall be limited to the lesser of (A) the amount of the settlement offer that the indemnified party
declined to accept plus the Losses of the indemnified party relating to such Indemnification Claim through the date of its rejection of the settlement offer or (B) the aggregate Losses of the Indemnified Party with respect to such Indemnification
Claim. If the indemnifying party makes any payment on any Indemnification Claim, the indemnifying party shall be subrogated, to the extent of such payment, to all rights and remedies of the indemnified party to any insurance benefits or other claims
of the indemnified party with respect to such Indemnification Claim. 
  
 (b) After any final decision, judgment or award shall have been rendered by a Governmental Body of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement shall have been consummated, or the
indemnified party and the indemnifying party shall have arrived at a mutually binding agreement with respect to an Indemnification Claim hereunder, the indemnified party shall forward to the indemnifying party notice of any sums due and owing by the
indemnifying party pursuant to this Agreement with respect to such matter. 
  
 7.5 Limitations on Indemnification. 
  
 (a) A Purchaser Indemnified Party may assert an Indemnification Claim pursuant to Section 7.2(a) with respect to representations and warranties of the Seller only to the extent the Purchaser Indemnified Party
gives notice of the Indemnification Claim pursuant to Section 7.4(a) before the expiration of the applicable time period set forth in Section 7.1 for such representation and warranty. Any Indemnification Claim not made in accordance
with Section 7.4(a) by the Purchaser Indemnified Parties on or before the applicable date set forth in Section 7.1, and Seller’s indemnification obligations with respect thereto, will be irrevocably and unconditionally released
and waived by the Purchaser Indemnified Parties. 
  

 19 








 (b) Notwithstanding the provisions of this Article 7, Seller shall not have any indemnification
obligations for Losses under Section 7.2, (i) for any individual item where the Loss relating thereto is less than $100,000 and (ii) in respect of each individual item where the Loss relating thereto is equal to or greater than $100,000,
unless the aggregate amount of all such Losses exceeds three (3%) percent of the Nominal Purchase Price, and then only to the extent of such excess. In no event shall the aggregate amount of Losses to be paid by Seller under Section 7.2
exceed ten (10%) percent of the Nominal Purchase Price. Notwithstanding the foregoing, in no event shall the aggregate indemnification to be paid by Seller under Section 7.2 with respect to a breach by Seller of the representations and
warranties contained in any of Sections 4.6, 4.10, 4.11, 4.12, 4.13 and 4.14 exceed the Purchase Price. 
  
 (c) No representation or warranty of Seller contained herein shall be deemed untrue or incorrect, and Seller shall not be deemed to have breached a
representation or warranty, as a consequence of the existence of any fact, circumstance or event of which (i) is disclosed in response to another representation or warranty contained in this Agreement or (ii) Purchaser is aware as of the Closing
Date. 
  
 (d) No Purchaser Indemnified Party shall have any right
to indemnification under this Article 7 in respect of any matter that is taken into account in the calculation of any adjustment to the Adjusted Purchase Price pursuant to this Agreement. 
  
 (e) The amount of any Losses for which indemnification is provided under this
Article 7 shall be net of any amounts actually recovered or recoverable by the indemnified party under insurance policies or otherwise, and net of any tax benefit realized by Purchaser, with respect to such Losses. 
  
 (f) For purposes of calculating the amount of any Losses for which
indemnification for any breach of any representation or warranty is provided under this Article 7 (but not for purposes of determining whether any particular representation or warranty contained herein has been breached), any materiality or
Material Adverse Effect qualifications in the applicable representations or warranties shall be ignored. 
  
 (g) Notwithstanding anything contained in this Agreement to the contrary, Purchaser, on behalf of itself and each of the other Purchaser Indemnified
Parties, acknowledges and agrees that, except for the representations and warranties contained in Article 4 (as modified by the Schedules hereto), neither Seller nor any other Person is making any express or implied representation or warranty
with respect to Seller, Vesco Holdings, VESCO, their respective Affiliates or the transactions contemplated by this Agreement, and Seller disclaims any representations or warranties, whether made by Seller, Vesco Holdings, VESCO or any of their
respective Affiliates, officers, directors, employees, agents or representatives. Any claims a Purchaser Indemnified Party may have for breach of representation or warranty shall be based solely on the representations and warranties of Seller set
forth in Article 4 (as modified by the Schedules hereto as 
  

 20 








 supplemented or amended). In furtherance of the foregoing, except for the representations and warranties contained in
Article 4 (as modified by the Schedules hereto), Purchaser, on behalf of itself and each of the other Purchaser Indemnified Parties, acknowledges and agrees that none of VESCO, Vesco Holdings, Seller, any of their respective Affiliates or any
other Person will have or be subject to any Liability to Purchaser or any other Person for, and Seller hereby disclaims all Liability and responsibility for, any representation, warranty, projection, forecast, statement, or information made,
communicated, or furnished (orally or in writing) to Purchaser or its Affiliates or representatives, including any confidential memoranda distributed on behalf of Vesco Holdings relating to VESCO or Vesco Holdings or other publications or data room
information provided to Purchaser or its Affiliates or representatives, or any other document or information in any form provided to Purchaser or its Affiliates or representatives in connection with the sale of the Vesco Holdings Membership Interest
and the transactions contemplated hereby (including any opinion, information, projection, or advice that may have been or may be provided to Purchaser or its Affiliates or representatives by any director, officer, employee, agent, consultant, or
representative of VESCO, Vesco Holdings or Seller or any of their respective Affiliates) or for Purchaser’s use of any such information. 
  
 (h) Purchaser, on behalf of itself and each of the other Purchaser Indemnified Parties, acknowledges that it has conducted to its satisfaction, its own
independent investigation of the condition, operations and business of VESCO and Vesco Holdings and, in making its determination to proceed with the transactions contemplated by this Agreement, each of the Purchaser Indemnified Parties has relied on
the results of Purchaser’s independent investigation. The disclosure of any matter or item in any schedule hereto shall not be deemed to constitute an acknowledgment that any such matter is required to be disclosed. 
  
 7.6 Tax Treatment of Indemnity Payments. Seller and Purchaser agree to
treat any indemnity payment made pursuant to this Article 7 as an adjustment to the Adjusted Purchase Price for federal, state, local and foreign income tax purposes. 
  
 7.7 NO CONSEQUENTIAL DAMAGES.

 understanding and agreement between the Parties with respect to the subject matter hereof. This Agreement can be amended,
supplemented or changed, and any provision hereof can be waived, only by written instrument making specific reference to this Agreement signed by the Party against whom enforcement of any such amendment, supplement, modification or waiver is sought.
No action taken pursuant to this Agreement, including any investigation by or on behalf of any Party, shall be deemed to constitute a waiver by the Party taking such action of compliance with any representation, warranty, covenant or agreement
contained herein. The waiver by any Party of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of
any Party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such Party preclude any other or further exercise
thereof or the exercise of any other right, power or remedy. 
  
 9.5 Governing Law. The provisions of this Agreement, all of the documents delivered pursuant hereto, their execution, performance or nonperformance, interpretation, construction and all matters based upon, arising out of or related
to this Agreement or the negotiation, execution or performance of this Agreement (whether in tort or contract) shall be governed by the Laws, both procedural and substantive, of the State of Delaware without regard to its conflict of laws provisions
that if applied might require the application of the Laws of another jurisdiction.

 9.7 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any Law or public policy,
all other terms or provisions of this Agreement shall nevertheless remain in full force and effect so long as the legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such
determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an
acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. 
  
 9.8 Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and
permitted assigns. Nothing in this Agreement shall create or be deemed to create any third party beneficiary rights in any person or entity not a party to this Agreement. No assignment of this Agreement or of any rights or obligations hereunder may
be made by either Seller or Purchaser, directly or indirectly (by operation of law or otherwise), without the prior written consent of the other Party (other than an assignment to an Affiliate) and any attempted assignment without the required
consents shall be void. No assignment of any 
  

 27 








 obligations hereunder shall relieve the assignor of its obligations hereunder, and any such assignor shall remain jointly
and severally liable for its obligations and the obligations of its permitted assignee. Upon any such permitted assignment, the references in this Agreement to Purchaser shall also apply to any such assignee unless the context otherwise requires.

  
 9.9 Non-Recourse. This Agreement may only be enforced
against, and any claims or causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against, the entities that are expressly identified as
Parties. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney or representative of Seller or any of their respective Affiliates shall have any Liability for any obligations or
liabilities of Seller under this Agreement of or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby and thereby. 
  
 9.10 Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this
Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. Once signed, any reproduction of this Agreement made by reliable means (e.g., photocopy, facsimile) is considered an original. 
  
 9.11 Time is of the Essence. With regard to the dates and time periods
set forth or referred to in this Agreement, TIME IS OF THE ESSENCE. 
  
 9.12 Specific Performance. Without limiting any other rights or remedies of the Parties, to the extent all of the conditions to Closing set forth in Article 8 have either been satisfied or waived and a Party fails to
consummate the Closing, the other Party shall have the right to seek a decree of specific performance to cause the breaching party to so consummate the Closing.
