and except as specified in Schedule 3.20, (i) each Welfare Plan for which contributions are claimed by the Company as deductions

and every case has complied, with all of the applicable requirements of Section 4980B of the Code, ERISA, Title XXII of the Public
Health Service Act and the Social Security Act, and (iv) all Welfare Plans may be amended or terminated at any time on or the Closing

ARTICLE X


INDEMNIFICATION


 


10.1 By Sellers.
From and after the Closing Date, the Sellers, jointly and severally, shall indemnify and hold harmless Buyer and its successors
and assigns, and their respective officers, directors, employees, Sellers, agents, Affiliates and any Person who controls any of
such Persons within the meaning of the Securities Act or the Exchange Act (each, a “Buyer Indemnified Party”) from
and against any liabilities, claims, demands, judgments, losses, costs, damages or expenses whatsoever (including reasonable attorneys’,
consultants’ and other professional fees and reasonable disbursements of every kind, nature and description incurred by such
Indemnified Party in connection therewith) (collectively, “Damages”) that such Buyer Indemnified Party may sustain,
suffer or incur and that result from, arise out of or relate to (a) any breach of any of the respective representations, warranties,
covenants or agreements of any Seller contained in this Agreement or in the Closing Certificates, (b) any Liability of any Seller
involving Taxes due and payable by, or imposed on the Company with respect to any Seller for any and all taxable periods ending
on or prior to the Closing (whether or not such Taxes have been due and payable), and (c) any Liability of the Company, the Business,
Sellers for any and all periods ending on or prior to the Closing except as disclosed in this Agreement, the Financial Statements
or other Schedule hereto (collectively, “Buyer Indemnifiable Damages”).


 


10.2 By Buyer.
From and after the Closing Date, Buyer shall, or in connection with Section 10.2 (c) shall cause the Company to indemnify and hold
harmless each Seller and its/his respective heirs, legal representatives, successors and assigns, and (if any) their respective
officers, directors, employees, agents, Affiliates and any person who controls such Persons with the meaning of the Exchange Act
(each a “Sellers Indemnified Party”) from and against any Damages that such Sellers Indemnified Party may sustain,
suffer or incur and that result from, arise out of or relate to: (a) any breach of any of the respective representations, warranties,
covenants or agreements of Buyer contained in this Agreement; (b) the nonfulfillment of any covenant, undertaking, agreement or
other obligation of Buyer under this Agreement and (c) Sellers’ capacities as directors and officers of the Company in respect
to any acts or omissions occurring at or prior to the Closing Date, to the fullest extent allowed by applicable law.

10.3 Procedure for Claims.


 


(a) Any Person that desires
to seek indemnification under any part of this Article X (each, an “Indemnified Party”) shall give notice (a “Claim
Notice”) to each party responsible or alleged to be responsible for indemnification hereunder (an “Indemnitor”)
prior to any applicable Expiration Date specified below. Such notice shall explain with specificity the nature of the claim, the
specific Article and section of this Agreement to which the claim relates and the parties known to be involved, and shall specify
the amount of the estimated damages relating thereto. If the matter to which a claim relates shall not have been resolved as of
the date of the Claim Notice, the Indemnified Party shall estimate the amount of the claim in the Claim Notice, but shall also
specify therein that the claim has not yet been liquidated (an “Unliquidated Claim”). If an Indemnified Party gives
a Claim Notice for an Unliquidated Claim, the Indemnified Party shall also give a second Claim Notice (the “Liquidated Claim
Notice”) within 60 days after the matter giving rise to the claim becomes finally resolved, and the Second Claim Notice shall
specify the amount of the claim. Each Indemnitor to which a Claim Notice is given shall respond to any Indemnified Party that has
given a Claim Notice (a “Claim Response”) within 60 days (the “Response Period”) after the later of (i)
the date that the Claim Notice is given or (ii) if a Claim Notice is first given with respect to an Unliquidated Claim, the date
on which the Liquidated Claim Notice is given. Any Claim Notice or Claim Response shall be given in accordance with the notice
requirements hereunder, and any Claim Response shall specify whether or not the Indemnitor giving the Claim Response disputes the
claim described in the Claim Notice. If any Indemnitor fails to give a Claim Response within the Response Period, such Indemnitor
shall be deemed not to dispute the claim described in the related Claim Notice. If any Indemnitor elects not to dispute a claim
described in a Claim Notice, whether by failing to give a timely Claim Response or otherwise, then the amount of such claim shall
be conclusively deemed to be an obligation of such Indemnitor. For the purposes of the immediately preceding sentence, an Indemnitor's
failure to give a timely Claim Response shall not be deemed an election not to dispute a Claim Notice unless the Indemnified Party
shall have given a second Claim Notice after expiration of the Response Period and, another 20 days after the date on which the
Indemnified Party shall have given such second Claim Notice shall have expired without the Indemnitor's having given a Claim Response
within such period.


 


(b) If any Indemnitor shall
be obligated to indemnify an Indemnified Party hereunder, such Indemnitor shall pay to such Indemnified Party within 30 days after
the last day of the Response Period the amount to which such Indemnified Party shall be entitled. In the event of a dispute as
to the amount or manner of indemnification under this Article X, the Indemnified Party may pursue whatever legal remedies may be
available for recovery of the Damages claimed from any Indemnitor in accordance with the arbitration provisions of this Agreement.
If any Indemnitor fails to pay all or part of any indemnification obligation when due, then such Indemnitor Party shall also be
obligated to pay to the applicable Indemnified Party interest on the unpaid amount for each day during which the obligation remains
unpaid at an annual rate equal to the Prime Rate. The Prime Rate in effect on the first business day of each calendar quarter shall
apply to the amount of the unpaid obligation during such calendar quarter.


 


10.4 Claims Period.
Any claim for indemnification under this Article X shall be made by giving a Claim Notice under Article 10.3 on or before the second
anniversary of the Closing (the "Expiration Date"). So long as an Indemnified Party gives a Claim Notice for an Unliquidated
Claim on or before the Expiration Date, such Indemnified Party shall be entitled to pursue its rights of indemnification regardless
of the date on which such Indemnified Party gives the related Liquidated Claim Notice.


 



    	25



    	 



    



 


10.5 Third Party Claims.


 


(a) If any third party
shall notify any Indemnified Party with respect to any actions, suits or other administrative or judicial proceedings (each, an
"Action") which may give rise to a claim for indemnification against any Indemnifying Party under this Article X, then
the Indemnified Party shall promptly (and in any event within five Business Days' after receiving notice of the Action) notify
each Indemnifying Party thereof in writing.


 


(b) Any Indemnifying Party
will have the right to assume and thereafter conduct the defense of the Action with counsel of his or its choice reasonably satisfactory
to the Indemnified Party; provided, however, that the Indemnifying Party will not consent to the entry of any judgment or enter
into any settlement with respect to the Action without the prior written consent of the Indemnified Party (which consent shall
not be unreasonably withheld) unless the judgment or proposed settlement involves only the payment of money damages and does not
impose an injunction or other equitable relief upon the Indemnified Party.


 


(c) Unless and until an
Indemnifying Party assumes the defense of the Action, the Indemnified Party may defend against the Action in any manner he or it
reasonably may deem appropriate.


 


(d) In no event will the
Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to any Action without the prior
written consent of each of the Indemnifying Parties (which consent shall not be unreasonably withheld).


 


10.6 Reduction for
Insurance. The amount which an Indemnifying Party is required to pay to, for, or on behalf of any Indemnified Party pursuant
to this Article X shall be reduced (including, without limitation, retroactively) by any insurance proceeds actually recovered
by or on behalf of the Indemnified Party that reduces the related indemnifiable loss (the "Indemnifiable Loss"). An amount
required to be paid, as so reduced, is hereinafter sometimes referred to as an "Indemnity Payment." If an Indemnified
Party shall have received, or if an Indemnifying Party shall have paid on its behalf, an Indemnity Payment in respect of an Indemnifiable
Loss and shall subsequently receive, directly or indirectly, insurance proceeds in respect of such Indemnifiable Loss, then such
Indemnified Party shall promptly pay to the Indemnifying Party the amount of such insurance proceeds, or, if less, the amount of
the Indemnity Payment. The parties hereto agree that the foregoing shall not affect the subrogation rights of any insurance company
making payments hereunder.


 


10.7 Exclusive
Remedy; Limitation of Liability. Buyer acknowledges and agrees that its sole and exclusive remedy with respect to any and
all claims relating to the subject matter of this Agreement shall be pursuant to the indemnification provisions set forth in this
Article 10. No Seller shall have any liability to Buyer or any Buyer indemnified person for any claim arising out of the negotiation,
execution or delivery of this Agreement, or the transactions provided for herein, whether for defense, indemnification or otherwise,
except as provided for in this Article 10. In furtherance of the foregoing, Buyer hereby waives, to the fullest extent permitted
under applicable law, any and all rights, claims and causes of action it or the Company may have against Sellers arising under
or based upon any Law or Environmental Law, or otherwise except to the extent specifically provided in this Article 10. Notwithstanding
the foregoing, nothing in this Agreement shall limit the rights of and remedies available to Buyer in the event of fraud or intentional
misconduct on the part of the Company or any Seller.
