      granted by the Sellers and the Seller Related Parties as indicated in Exhibit 2.3 to secure liabilities of the Group Companies. The Sellers’ Security shall be released with effect as of no later
      than forty-five (45) days after the Closing Date to the extent legally permissible and to the extent the relevant beneficiary consents to such release (except for the land charge listed in Exhibit 2.3 with

      respect to which, subject to this Section 2.3, the release of the land charge shall be agreed with the relevant bank no later than forty-five (45), but the release may take longer as it will require registration in the land register). The Sellers’
      Security shall be replaced to the extent necessary by guarantees and securities of the Purchaser or its Affiliates (including the Group Companies), provided that there shall be no obligation of the Purchaser to provide a guarantee or security for
      obligations of persons or legal entities other than the Group Companies. To the extent no full release has occurred within forty-five (45) days after the Closing Date, the Purchaser shall procure (steht dafür ein)
      the due performance by the Company of all of the obligations to Sparkasse Hannover and Volksbank Hannover which are the subject of the Sellers’ Security, and to do nothing (whether by act or omission) which would prevent or hinder the due performance
      of such obligations or impair the ability of the Company to perform such obligations. The Purchaser shall indemnify and hold harmless (freistellen, schadlos halten) the Sellers and any Seller Related Party
      that provided Seller’s Security with regard to obligations of the Group Companies from any claims asserted under the respective Sellers’ Security against the respective security provider following the Closing Date as long as full release and
      discharge of the respective Sellers’ Security in accordance with the terms of this Agreement remains pending.

    The purchase price for the Sold Shares (the “Purchase Price”) shall be determined as follows:

     

    	

          	(a)	
            EUR 27,750,000 (in words: Euro twenty-seven million seven hundred fifty thousand);

            plus, the value of the Earn-out Shares to be transferred to Sellers, if any, subject to and in accordance with Section 4.5 (the “Earn-out”).

            Preliminary Cash Purchase Price

          

     

    On the Closing Date, the Purchaser (or an Affiliate acting on behalf of the Purchaser) shall pay with respect to the Purchase Price an aggregate amount of EUR 28,347,000.00 (in words: Euro
      twenty-eight million three hundred forty-seven thousand) (the “Preliminary Cash Purchase Price”) minus the Holdback and disregarding the Earn-Out to the Sellers as
      follows:

     

    	

          	(i)	
            to the Seller 1 an amount of EUR 13,732,759.60 (in words: Euro thirteen million seven hundred thirty-two thousand seven hundred fifty-nine and sixty cents); and

    Exhibit 4.2
        contains a good faith estimate of the Sellers, which was used to calculate the Preliminary Cash Purchase Price. For the avoidance of doubt, the Purchase Price (other than the Earn-out) shall be calculated in accordance with Sections 4.1 and 5 and
        be based on the relevant actual amounts as of the Purchase Price Accounts Date. Further, the principles for the calculation of the Purchase Price (other than the Earn-out) set forth in Sections 4.1 and 5 shall apply irrespective of how the good

            Holdback

          

     

    	

          	(a)	
            The Purchaser shall be entitled to hold back a portion of the Purchase Price in the aggregate amount of EUR 1,250,000 (in words: Euro one million two hundred fifty thousand) (the “Holdback“) from the
              Preliminary Cash Purchase Price payable on the Closing Date. The Holdback shall serve as collateral for any claim of the Purchaser under or in connection with this Agreement, including, for the avoidance of doubt, any claim of the Purchaser
              for the payment of a Purchase Price Shortfall Amount (collectively, the “Holdback Claims”). The Holdback shall not be an escrow but a holdback only.

          

     

    	

          	(b)	
            If and to the extent (i) the relevant Seller acknowledges a Holdback Claim by the Purchaser, (ii) the relevant Seller and the Purchaser have settled a Holdback Claim or (iii) a competent arbitral tribunal (Schiedsgericht)
              (in accordance with Section 18.11 below) determines by final, non-appealable decision that the (certain) Sellers are liable for the Holdback Claim by the Purchaser, the Purchaser shall be entitled to finally retain from the Holdback the
              amount of such Holdback Claim and such amount shall be deducted from the portion of the Purchase Price payable to the relevant Seller. If the Purchaser finally retains an amount of the Holdback in connection with any claim of the Purchaser
              for the payment of a Purchase Price Shortfall Amount (if any), the Sellers shall promptly restore the Holdback by payment of the respective amount to the Purchaser into the Purchaser’s Bank Account.

          

     

    	

          	(c)	
            Subject to Section 4.4(d) below, within eighteen (18) months after the Closing Date (the “Holdback Period”), the Purchaser shall pay to each Seller a portion of the Holdback which corresponds to the
              relevant Seller’s Pro-Rata Participation in the Holdback minus the aggregate amount of all Holdback Claims against such Seller, which have been resolved in accordance with Section 4.4(b)(i), (ii) or (iii) above (such amount the “Remaining Holdback”).

          

     

    Each Seller’s respective Pro-Rata Participation in the Remaining Holdback shall be paid into the respective Individual Seller’s Bank Account.

     

    	

          	(d)	
            If the Purchaser has issued a notice (the “Holdback Claim Notice”) to a Seller within the Holdback Period which states in reasonable detail the nature and amount of a Holdback Claim and such Holdback
              Claim has not been resolved between the relevant Parties within the Holdback Period, the Purchaser shall not be obliged to pay (a portion of) the Remaining Holdback to the relevant Seller(s) to the extent the Purchaser reasonably expects such
              amount to be required for resolving the Holdback Claim or any other Holdback Claim (the “Holdback Retainer”). If the Parties cannot resolve the underlying Holdback Claim as stated in the Holdback Claim
              Notice within three (3) months following the Holdback Period, the Purchaser shall be obliged to pay the Holdback Retainer to the relevant Seller, unless (i) the Purchaser has initiated arbitration proceedings with respect to such Holdback
              Claim in accordance with Section 18.11 below or (ii) such Holdback Retainer is required to cover any other Holdback Claim. After initiation of arbitration proceedings, the payment of the Holdback Retainer shall be finally settled by (i) the
              arbitral tribunal (Schiedsgericht) or (ii) mutual agreement between the relevant Seller(s) and the Purchaser.

            Earn-out

          

     

    As part of the Purchase Price and subject to the terms and conditions of this Section 4.5 including the achievement of the Earn-out Milestones set forth herein, the Sellers shall be entitled to a
      maximum aggregate number of HSKA Shares that is equivalent to the quotient of (i) EUR 13,750,000 (in words: Euro thirteen million seven hundred fifty thousand) and (ii) the 30-trading-day weighted average trading price of HSKA Shares in the period
      preceding the Closing Date and the 30 Business Days average US Dollar/Euro exchange rate in the period preceding the Closing Date and published by the European Central Bank on the webpage
      https://www.ecb.europa.eu/stats/policy_and_exchange_rates/euro_reference_exchange_rates/html/index.en.html (the “Earn-out Shares”). (The number of Earn-out Shares to which Sellers are entitled to receive shall
      be adjusted by and to the extent of any subsequent split, reclassification or other adjustment of the HKSA Shares.) The Earn-out Shares, if any, shall be issued or transferred as follows and shall be apportioned to the Sellers based on their Pro-Rata
      Participation:

     

    	

          	(a)	
            [***]% of the Earn-out Shares shall become due upon the development and commercialization of a globally deployable cloud‐native PIMS (Product Information Management Solution) of a quality that middle-level and above VetZ users will utilize (the “Cloud PIMS”) with at least [***] (in words: [***]) net active veterinary practices as customers of the Company
              who are paying the Company for the use of Cloud PIMS and are not on a trial subscription (or using other testing arrangements) only (which excludes cloud-based customers acquired following the Signing Date (irrespective of the legal form of
              the acquisition (assumption of contract, asset deal, share deal or otherwise)) but includes customers that are current on‐premise users of VetZ’s software products) (such users, the “Net Active Users”)
              based in any country (other than in the United States of America, Canada and Australia), it being understood that “commercialization” means any active sale effort in commerce to non-affiliated users;

          

     

    	

          	(b)	
            [***]% of the Earn-out Shares shall become due upon the development and commercialization of a Cloud PIMS that is utilized by at least [***] Net Active Users based in the United States of America, Canada and Australia; and

          

     

    	

          	(c)	
            [***]% of the Earn-out Shares shall become due when consolidated annual net revenue of the Group attributable to global practice management software and related software revenue (including revenue resulting from license fees and related
              software transaction fees for ‘petsXL’,‘easyVET’ and ‘vetsXL’) equals or exceeds EUR [***] (in words: Euro [***]) in any fiscal year (including a 12 months’ period) based on billings in the ordinary course of business, provided, that the
              consolidated annual net revenue of the Group and the Purchaser and its Affiliates (other than the Group Companies) generated with customers based in Germany, Austria and Switzerland and attributable to digital x-ray imaging (DXR) products of the Purchaser and its Affiliates (other than the Group Companies) shall be credited towards the EUR [***] (in words: Euro [***]) up to a maximum amount of EUR [***] (in words: Euro [***]) in
              the DXR product revenue in any fiscal year (including a 12 months’ period) based on billings in the ordinary course of business. All billings and revenue referred to in this paragraph (c) shall be determined in accordance with US GAAP as
              applied by US HoldCo for reporting purposes in a manner consistent with past practice. For the avoidance of doubt, all net revenue that is credited towards the targets in this paragraph shall not count more than once in that intercompany
              revenue will be eliminated and revenue will be recorded on a consolidated basis;

          

     

    each of the milestones under lit. (a) through (c), an “Earn-out Milestone”.

     

    In case of a rounding difference when applying the percentage stated under lit. (a), (b) and (c), the number of Earn-out Shares to be issued or transferred will be rounded up to the nearest whole
      number of Earn-out Shares. The Earn-out Milestones pursuant to lit. (a) through (c) above can be achieved in any chronological order. Each Earn-out Milestone can only be achieved once and not partially. The Sellers shall not be entitled to Earn-out
      Shares with respect to a certain Earn-out Milestone if such Earn-out Milestone is not achieved before the sixth (6th) anniversary of the Closing Date and the Sellers’ claim for such unearned portion of the Earn-out Shares shall then lapse and cease
      to exist. 

    

     

    
      19

      
        

    

    The number of Earn-out Shares shall not be less than zero.

     

    Within a period of 6 (six) years following the Closing Date, the Purchaser shall upon written request of the Sellers (acting jointly) (i) provide the Sellers one time per calendar year with a report
      setting forth the status of progress to achieve all Earn-out Milestones since the Closing Date (in case of the first report) as of the end of the preceding calendar quarter and (ii) one time per calendar year, the Purchaser shall invite the Seller’s
      Representative to and hold a conference call (to be scheduled by the Purchaser with reasonably sufficient lead time between the day on which the written request is received by the Purchaser and the day of the conference call) to respond orally to
      reasonable queries received from the Sellers in relation to the achievement of all Earn-out Milestones which queries shall be included in the written request for the relevant conference call.

     

    Promptly after delivery of written confirmation by the Purchaser that any of the foregoing Earn-out Milestones have been achieved, the Purchaser shall cause US HoldCo to issue the applicable number
      of Earn-out Shares or transfer to the Seller such number of Earn-out Shares to the Sellers (which are existing at the date the Earn-out Milestone occurs) and in any event within ten (10) Business Days of the date such Earn-out Milestone has been
      achieved. Purchaser may offset any portion of the Earn-Out due against any amounts which may be due by a Seller or a Sellers’ Guarantor under this Agreement or any related agreement.

     

    Any Earn-out Shares issued pursuant to this Section 4.5 shall be “restricted securities” under the United States Securities Laws and shall not have been registered under the Securities Act of 1933,
      as amended (the “Securities Act”), or any applicable state securities laws, and shall bear an appropriate legend to the effect that such Earn-out Shares may be sold only pursuant to an effective registration
      statement under the Securities Act or under an exemption from such registration and in compliance with applicable United States federal and state securities laws.

     

    The Company shall prepare, and, as soon as practicable but in no event later than forty-five (45) days after the Closing Date, file with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement under the Securities Act on appropriate form covering the resale of the full amount of the Earn-out Shares. The Company shall use its commercially reasonable efforts to have
      the registration statement declared effective by the Commission as soon as practicable, but in no event later than the date, which shall be either: (i) in the event that the Commission does not review the registration statement, ninety (90) days
      after the Closing Date, or (ii) in the event that the Commission reviews the Registration Statement, one hundred and twenty (180) days after the Closing Date (but in any event, no later than four Business Days following the Commission indicating that
      it has no further comments on the registration statement).  Nothing contained herein shall limit or restrict any holder of restricted securities from selling any such shares under Rule 144 and nothing shall prohibit or restrict any Seller or
      affiliate (including any family member) from purchasing any securities of US Holdco on the open market including any derivatives thereof.

     

    With regard to VAT, Section 4.8 shall apply mutatis mutandis to the Earn-out.

     

    	4.6	
            Allocation

          

     

    The Purchase Price shall be allocated among the Sellers pro rata to the nominal amounts of the Sold Shares sold and assigned by the relevant Sellers under this Agreement. Such pro rata participation of the respective Seller in the Purchase Price in percent is herein referred to as such Seller’s “Pro-Rata Participation”. Upon final determination of
      the Purchase Price pursuant to Section 5 (other than the Earn-out), the portion of the Purchase Price to be received by a Seller according to such Pro-Rata Participation shall be referred to as such Seller’s “Absolute
        Participation”, which shall be increased by any portion received under the Earn-out.

    	4.7	
            Adjustments to the Purchase Price

          

     

    The Sellers and the Purchaser are in agreement that any payment by a Seller to the Purchaser or by the Purchaser to a Seller under this Agreement (other than the payment of the Preliminary Cash
      Purchase Price and the payment of the Purchase Price Excess Amount or, as the case may be, Purchase Price Shortfall Amount), in particular any payments pursuant to Sections 9, 11 and 12, as well as any restitution in kind provided under this
      Agreement shall be treated by the Parties as adjustments to the Purchase Price, i.e., an increase or reduction of the Purchase Price and of the relevant Seller’s Absolute Participation, respectively. For the
      avoidance of doubt, the foregoing does not affect the content of the definition of the Purchase Price nor, consequently, the caps pursuant to Section 11.4(b).

     

    	4.8	
            VAT

          

     

    It is the Parties’ understanding that all transactions contemplated under this Agreement are either not subject to VAT (umsatzsteuerbar) or exempt (befreit) from VAT. No Seller shall exercise any right to opt for VAT with respect to the sale and assignment of the Sold Shares under this Agreement. If contrary to the Parties’ understanding a Tax Authority takes
      the view that VAT becomes payable and no Seller has waived any VAT exemption, VAT shall be paid by the Purchaser in addition to the Purchase Price, i.e., the Purchase Price is exclusive of any VAT.  In such
      an instance, an invoice shall be provided to the Purchaser by Sellers.

            FINAL DETERMINATION AND PAYMENT OF THE PURCHASE PRICE

          

     

    	5.1	
            Final Determination of the Purchase Price

          

     

    	

          	(a)	
            The Purchase Price (other than the Earn-Out) shall be considered finally determined once the Purchase Price Accounts have become final and binding upon the Sellers and the Purchaser pursuant to this Section 5.

          

     

    	

          	(b)	
            If the Purchase Price (other than the Earn-Out) exceeds the Preliminary Cash Purchase Price (the “Purchase Price Excess Amount”), the Purchaser shall pay an amount equal to the respective Seller’s
              Pro-Rata Participation of the Purchase Price Excess Amount to the relevant Seller into the respective Individual Seller’s Bank Account.

          

     

    	

          	(c)	
            If the Purchase Price (other than the Earn-Out) falls short of the Preliminary Cash Purchase Price (the “Purchase Price Shortfall Amount”), the respective Seller shall pay an amount equal to the
              relevant Seller’s Pro-Rata Participation of the Purchase Price Shortfall Amount to the Purchaser into the Purchaser’s Bank Account.

          

     

    	

          	(d)	
            Any such amount to be paid by either the Purchaser or the Sellers under Sections 5.1(b) and (c), as the case may be, shall be paid within twenty (20) Business Days after the Purchase Price Accounts have become final and binding upon the
              Sellers and the Purchaser.

          

     

    	5.2

            Miscellaneous

          

     

    	

          	(a)	
            Prior to the date hereof, the Purchaser has had access to information about the Group Companies provided by the Sellers, completed an in-depth due diligence review including a Q&A process and made its own evaluation of the adequacy and

          	(a)	
            Consequences of a Breach. Subject to the provisions of this Section 11, if and to the extent any Sellers’ Guarantee is not true and
                correct or not complete (a “Breach”), the Sellers shall put the Purchaser or, at the election of the Purchaser, the Group Companies (or, at the election of the Purchaser, with respect to the Sellers’
                Guarantee pursuant to Section 3.4 of Exhibit 9.1, US HoldCo), into the same position it or they would be in, if the Breach had not occurred (Naturalrestitution).

                If and to the extent restitution in kind has not been effected by the Sellers within a period of two (2) month after a written request for such remediation has been made by the Purchaser, the Purchaser shall be entitled to request from the
                Sellers compensation in cash (Schadensersatz in Geld) for any Losses (as defined below) incurred by the Purchaser and the Purchaser’s Affiliates (including the Group Companies).

          

     

    	

          	(b)	
            Definition of Losses. “Losses” shall mean all damages (within the meaning of sections 249 et seqq. of the German Civil Code (BGB)) incurred, (i) including any lost profit (entgangener Gewinn) incurred on the
                level of any Group Company but (ii) excluding (x) any actual reduction in value (Minderung) of any Group Company, (y) any consequential damages (Folgeschäden),

                which are not foreseeable (other than lost profit pursuant to lit. (i)), and (z) any lost profit (entgangener Gewinn) incurred on the level of the Purchaser.

          

     

    	

          	(c)	
            Computation of Losses. The present value of any benefits received by the Purchaser or a Group Company in connection with or as
                result of the Breach (including, without limitation, Tax Benefits and savings, and increases in the value of any asset owned by a Group Company (Abzug neu für Alt)) shall be deducted for the purpose
                of computing the Losses (Vorteilsausgleich).

          

     

    
      31

      
        

    

    	

          	(d)	
            Exclusions of Sellers’ Liability. The Sellers shall not be liable for a Breach (except for any Breach of a Fundamental Guarantee),
                if and only to the extent that (i.e., the Sellers are still (partially) liable for a Breach and the Purchaser may still bring a claim to the extent a Breach is only partially affected by an exclusion
                pursuant to (i) to (iii) below):

          

     

    	

          	(i)	
            either the Purchaser or, after Closing, a Group Company have caused or participated in causing (verursacht oder mitverursacht) or have aggravated such Breach or any Losses resulting therefrom or
              failed to mitigate Losses pursuant to section 254 of the German Civil Code (BGB);

          

     

    	

          	(ii)	
            the matter underlying the Breach has been specifically taken into account in the Purchase Price Accounts as a write-off (Abschreibung), value adjustment (Wertberichtigung),

              liability (Verbindlichkeit) or provision (Rückstellung), provided in each case that it has reduced the Purchase Price;
              or

          

     

    	

          	(iii)	
            the Losses are recovered from a third party (other than the Company or any of its Affiliates) or under an insurance policy.

          

     

    	

          	(e)	
            Knowledge of the Purchaser. Other than in case of a Breach relating to a Fundamental Guarantee, the Sellers shall not be liable for
                a Breach if and to the extent the facts and circumstances underlying the Breach were actually known (positive Kenntnis) by the Purchaser, provided that the Purchaser shall be deemed to have actual
                knowledge of the fact and circumstances which were Fairly Disclosed in the Data Room Documents. “Fairly Disclosed” means that the relevant facts, matters and
                circumstances on which the Breach is based were apparent from the Data Room Documents and disclosed in a sufficiently detailed manner on the face of such disclosure so that a reasonable purchaser understands in general the nature, scope and
                financial impact of the fact and circumstances disclosed and the fact that it breaches a specified Sellers’ Guarantee without needing to consider or request any other information or documents not disclosed in the Data Room Documents which
                also implies that the relevant facts, matters or circumstances made available in the Data Room were located in an area of the Data Room where the respective facts, matters or circumstances would be reasonably expected to be disclosed by the
                Seller and identified by the Purchaser. “Data Room Documents” means the documents disclosed in the virtual data room set up for Project Bingo (the “Data Room”). To the extent Data Room Documents are blackened they are not Fairly Disclosed.

          

     

    An electronic copy (“Data Device”) of the Data Room Documents shall be deposited on the date hereof with the acting notary, the Sellers and the Purchaser for
      purposes of providing evidence of the documents disclosed in the Data Room. The notary shall store the Data Device in safe keeping until the earlier of (i) the expiry of six (6) months after the date on which all Parties to the SPA have confirmed to
      the notary in writing that the statute of limitation periods in the SPA have expired and (ii) the expiry of ten years following the Closing Date (the “Deposit Period”). During the Deposit Period, each of the
      Parties shall after the Closing Date, upon reasonable advance notice and during normal business hours, be entitled to inspect the Data Device and review and/or make copies of, in both cases with their own technical equipment, the data contained on
      such Data Device in the notary’s presence (or the presence of a person authorised by the notary), provided that the notary has promptly notified all other Parties if such a request for inspection is made by a Party and given all other Parties with
      reasonable advance notice the possibility to be present during such inspection if they so wish. The notary is instructed to physically hand out the Data Device to any person upon the respective joint written request of all Parties. Upon expiry of the
      Deposit Period, the notary shall physically hand over the Data Device to the Company.

          	(f)	
            Exclusions. Section 442 para. 1 of the German Civil Code (BGB) as well as section 377 HGB
                and the principles contained therein shall not apply to this Agreement.

          

     

    	11.2	
            Breach Notice

          

     

    If the Purchaser obtains actual knowledge that a Breach has occurred, the Purchaser shall, as soon as reasonably practicable, give the Sellers written notice thereof (the “Breach Notice”). Knowledge of the Group Companies shall not be attributed to the Purchaser (keine Wissenszurechnung). The Breach Notice shall state in reasonable detail the
      nature of the alleged Breach and, to the extent feasible, the amount of Losses resulting therefrom. For the avoidance of doubt, in the event of a failure of the Purchaser to comply, in respect of relevant circumstances, with its notification
      obligations pursuant to the first sentence of this Section 11.2 the respective claims of the Purchaser shall not be precluded or forfeited (verwirkt), except to the extent that any increase of the damage is
      attributable to the Purchaser’s failure to give timely a Breach Notice in accordance with this Section 11.2.

     

    	11.3	
            Third Party Claims

          

     

    If a claim of a third party is asserted against the Purchaser or the Company after Closing which may lead to a liability of the Sellers for a Breach, the following shall apply:

     

    	

          	(a)	
            Conduct. The Purchaser shall, and shall direct the Company to, (i) made available to the Sellers a PDF copy of the third party claim
                and (ii) give the Sellers (acting jointly) the opportunity to comment on, and discuss with the Purchaser, any measures the Purchaser or the Company proposes to take or omit in connection with such claim. If the Sellers (acting jointly) have
                acknowledged in writing that the Purchaser has a claim against the Sellers in principle (dem Grunde nach), the Sellers (acting jointly) shall have, at their own costs, the right to defend the claim
                by all appropriate proceedings and shall have the sole power to direct and control such defense, in particular, without limitation, the Sellers may (x) participate in and direct all negotiations and correspondence with the third party, (y)
                appoint and instruct counsel acting, if necessary, in the name of the Purchaser or the Company, and (z) require that the claim be litigated or settled in accordance with the Sellers’ instructions (acting jointly). The Sellers (acting
                jointly) shall conduct such proceedings in good faith with due regard to the concerns and interests of the Purchaser and the Company.

          

     

    	

          	(b)	
            Cooperation. The Purchaser and the Company shall cooperate with the Sellers in the defense of any third party claim to the extent
                reasonable and practicable, provide the Sellers (acting jointly) and its representatives reasonable access to all relevant business records and documents and permit the Sellers (acting jointly) and its representatives, to the extent
                reasonable and practicable, to consult with the directors, employees and representatives of the Purchaser and the Company at usual business hours. All costs and expenses incurred by the Sellers in defending such claim shall be borne by the
                Sellers.

          

     

    	

          	(c)	
            Failure to Comply. For the avoidance of doubt, in the event of a failure of the Purchaser to comply with its obligations pursuant to
                this Section 11.3 the respective claims of the Purchaser shall not be precluded or forfeited (verwirkt), except to the extent that any increase of the damage is attributable to the Purchaser’s
                failure to fully comply with this Section 11.3.

              Limitations of Sellers’ Liability

            

    

    

    

    	

          	(a)	
            De Minimis Amount; Deductible Amount. The Sellers shall be liable for Losses resulting from an individual Breach (other than for
                Breaches of Fundamental Guarantees) only if such Losses exceed an amount of EUR 25,000 (the “De Minimis Amount”)  and until the aggregate amount of individual Breaches exceeds an aggregate amount of
                EUR 300,000 (Freigrenze) (“Threshold”). In case the sum of the individual claims exceeding the De Minimis Amount exceeds the Threshold, the Purchaser may not
                only claim the amount exceeding the Threshold, but the entire amount of the damage incurred. A series of claims for a Breach related to substantially the same or equal underlying circumstances (vergleichbarer Lebenssachverhalt) shall be treated as a single Breach for purposes of this Section 11.4.

          

     

    	

          	(b)	
            Caps.

            General Cap. The Sellers’ aggregate liability for Breaches of the Sellers’ Guarantees (other than for Breaches of the Fundamental
                Guarantees) shall be limited to an aggregate maximum amount equal to fifteen percent (15%) of the Purchase Price actually received by the Sellers (the “General Cap”) and each Seller’s individual
                liability for Breaches of the Sellers’ Guarantees (other than for Breaches of the Fundamental Guarantees) shall be limited to its Pro-Rata Participation in the General Cap.

          

     

    	

          	(ii)	
            Overall Cap. The Sellers’ aggregate liability for Breaches of Fundamental Guarantees as well as all other claims under this
                Agreement shall in any event be limited to an aggregate maximum amount of 100% of the Purchase Price actually received by the Sellers.

        Claim”). However, the Sellers shall not be obliged to pay Relevant Taxes

     

    	

          	(a)

          	(b)	
            if and to the extent that the Relevant Taxes are the result of (i) any change in the accounting and taxation principles or practices of the Company initiated or introduced by the Purchaser or at the request of the Purchaser after the
              Closing Date with regard to Pre-Accounts Date Tax Periods, or (ii) any transaction, action or omission (including the change in the exercise of any Tax election right, the approval or implementation of any reorganization measure or the sale
              of any asset) taken by Purchaser or the Company after the Closing Date with regard to Pre-Accounts Date Tax Periods, unless such change, transaction, action or measure is required in order to comply with Applicable Law or is approved by the

              4% per annum, applying a Tax rate applicable by law in the relevant taxable period and the expected time period in which such Tax Benefits can be realized but for a maximum of three (3) years after the Closing Date and under the assumption
              that the Purchaser or the Company, as applicable, is in a Tax paying position.

          

     

    	

          	(d)	
            if the Purchaser fails to comply with a covenant, obligation or any other kind of commitment set forth in this Section 12 but only if and to the extent that such failure (i) results in the exclusion of the Sellers from any remedies against
              the respective Tax and (ii) has caused or increased the Relevant Taxes;

          

     

    	

          	(e)	
            if and to the extent the Purchaser or the Group Companies (after the Closing Date due to circumstance initiated and caused after the Closing Date) have participated in causing (mitverursacht) such
              Purchaser’s claim within the meaning of section 254 para. 1 of the German Civil Code and has failed to mitigate damages pursuant to section 254 para. 2 of the German Civil Code; and

              sold, liquidated or otherwise disposed (including in Poland (including VetZ Sp. z o.o)) or other subsidiaries of the Company which are not operative any more as of the Closing Date (including costs for winding up/liquidation). In addition,
              the Sellers shall indemnify the Purchaser and, at the request of the Purchaser, the Group Companies as set forth in Exhibit 13.1(b).

    The Parties agree to execute, or cause to be executed all agreements and documents and to take, or cause to be taken, all other actions necessary under Applicable Laws and regulations to
      consummate the transactions contemplated by this Agreement.

     

    	14.2	
            No Interferences

    The Sellers shall provide as soon as reasonably practicable such information regarding the Business and affairs of the Group Companies as the Purchaser or the Purchaser’s Affiliates may reasonably

    	15.1	
            Non-Compete

          

     

    Each of the Sellers and the Guarantors undertakes not to, and shall procure that none of its Affiliates will, for a period of five (5) years from the Closing Date, however only for a period
      legally permissible, engage or be concerned in or otherwise support (as an employee, shareholder, consultant, board member or otherwise) any activity which competes with or results in competition with the Business of any Group Company. In particular,
      each of the Sellers and the Guarantors shall not establish or acquire, or acquire shares in, any business or business entity which would, directly or indirectly, compete with the Business of any Group Company (these obligations collectively the “Non-Compete-Covenant”). The regional scope of the Non-Compete-Covenant shall be equivalent to the regional scope of the Business; for the avoidance of doubt, it extends to such territories which any Group Company
      was planning to enter at the Closing Date, and for which investments to prepare such market entry were made prior to the Closing Date. It is understood, however, that each of the Sellers or any of its Affiliates (including the Guarantors) shall be
      entitled to acquire shares through an index or investment fund of up to one (1) percent of the voting stock in any company conducting a competing business and listed on a stock exchange.

     

    Should the five (5) year time period of the Non-Compete-Covenant eventually be regarded as invalid as a matter of law, the period of the Non-Compete-Covenant shall be reduced to such maximum
      period which has to be considered legally valid beyond doubt, beginning on the Closing Date. If any provision of the Non-Compete-Covenant is or becomes invalid or if it should prove to be incomplete, the remaining provisions shall not be affected
      thereby. The invalid provision shall be deemed replaced by or the incomplete provision shall be deemed completed by a legally valid provision which comes as close as possible to the economic purpose pursued by the Parties and which the Parties would
      have agreed upon had they been aware of the invalidity or incompleteness of the provision concerned. The same shall apply if the Non-Compete-Covenant does not contain a provision, which it needs to contain in order to give full effect to the economic
      purpose expressed herein.

     

    	15.2	
            Non-Solicit

          

     

    Each of the Sellers and the Guarantors undertake not to, and shall procure (dafür einstehen) that its Seller Related Parties will not, for a period of five
      (5) years from the Closing solicit or entice away (abwerben), a director, officer or employee of a Group Company.

     

    	15.3	
            Seller Related Party

          

     

    If any Seller Related Party is engaged in any conduct referred to in Sections 15.1 and/or 15.2, it shall be assumed that the relevant Seller is engaged in such conduct indirectly. The limitations
      of the non-compete covenant pursuant to pursuant to Section 15.1 shall apply mutatis mutandis to this Section 15.3.

              its intention to disclose such information and take into account the reasonable comments of the other Parties and shall limit any disclosure to the minimum required);

          

     

    	

          	(iii)	
            disclosure is of Confidential Information (i) which was lawfully in the possession of the receiving Party or any of its Representatives without any obligation of secrecy before its being received or held, (ii) which was independently

              Sellers disclose any Confidential Information of the Target Companies or on the Target Companies business;

          

     

    	

          	(iv)	
            disclosure is of Confidential Information which has previously become publicly available other than through the disclosing Party’s action or failure to act (or that of its Representatives); or

          

     

    	

          	(v)	
            disclosure is required for the purpose of the performance by the disclosing Party of its obligations or the exercise of its rights under this Agreement, including in connection with any arbitral or judicial proceedings arising out of this
              Agreement, provided that, prior to such disclosure, each recipient is bound by appropriate confidentiality undertakings.

          

     

    	

          	(c)	
            The Purchaser shall be permitted to disclose Confidential Information to its Affiliates and its and its’ Affiliates current and future financing sources and its and their advisers on a need-to-know basis and subject to appropriate
              confidentiality undertakings.

          

     

    	

          	(d)	
            Each of the Sellers, the Guarantors and the Purchaser undertakes that it (and its Representatives) shall only disclose Confidential Information as permitted by this Section 16 if it is reasonably required.

    No press release or other public announcement concerning the transactions contemplated by this Agreement shall be made by either Party unless the form and text of such announcement shall first
      have been approved by the Sellers (in case of a disclosure by the Purchaser) or the Purchaser (in case of a disclosure by a Seller) except that, if a Party is required by Law or by applicable stock exchange regulations or by SEC to make an
      announcement, it may do so after first consulting with the other Parties. If any Party is required by Law or by applicable stock exchange regulations or by the SEC to a disclosure of the contents of this Agreement and/or to make an announcement, it
      shall to the extent legally permitted limit any disclosure or announcement to the minimum required by statute or the authorities and cooperate with the respective other Parties (upon request) with respect to all reasonable steps to resist or avoid
      such disclosure or announcement. The Parties shall make a joint press release regarding the transaction contemplated by this Agreement, the content of which shall be agreed between the Parties in due course and in good faith.

            No Insolvency. No bankruptcy or insolvency or equivalent proceedings concerning the Sellers’ Guarantors have been applied for and
                (ii) no circumstances exist which would trigger the obligation to apply for any bankruptcy, insolvency or equivalent proceedings in any jurisdiction under applicable Law. Neither Sellers’ Guarantor has stopped or suspended payment of its
                debts, becomes unable to pay its debts or otherwise becomes insolvent, illiquid or over-indebted (überschuldet). No assets of the Sellers’ Guarantors have been seized by or on behalf of any third
                party nor are any foreclosure, forfeiture, execution or enforcement proceedings pending or threatened in writing with respect to the Sellers’ Guarantors or its respective assets.

          

     

    	

          	(iv)	
            Binding Agreement. This Agreement and all other agreements executed or to be executed in connection therewith have been or will be
                duly executed on behalf of the Sellers’ Guarantors and constitute binding obligations of the Sellers’ Guarantors, enforceable against them in accordance with the respective terms and conditions.

            The Purchaser’s Guarantor’s Guarantee

          

     

    The Purchaser’s Guarantor hereby unconditionally and irrevocably guarantees (Garantie; not Bürgschaft) to
      the Sellers the proper satisfaction of the payment of the Purchase Price (including the Earn-Out and the Holdback) subject to and in accordance with this Agreement. The Purchaser’s Guarantor hereby waives any rights which it may have to require the
      Sellers to proceed first against or claim payment from the Purchaser, such that as between the Sellers on the one hand and the Purchaser’s Guarantor on the other hand, the latter shall be liable as principal debtor as if it had entered into the
      undertaking to perform such payment obligations under this Agreement itself. A payment of (any portion of) the Purchase Price made by the Purchaser’s Guarantor shall have debt discharging effect for the Purchaser towards the Sellers.

              registered post or courier, or, (ii) transmission, if delivered by telefax or email, provided in case of telefax that the person sending the telefax has received a transmission receipt confirming a successful transmission thereof. The receipt

            Sellers’ and the Guarantors’ Representative

          

     

    	

          	(a)	
            Each Seller and each Guarantor agrees that Seller 1 (or any successor as may be designated by all Sellers and the Guarantors and notified to the Purchaser in accordance with Section 18.1 (“Sellers’
                Representative”) shall act as its authorized representative (Stellvertreter) under this Agreement and shall be entitled to take such action on behalf of all Sellers and the Guarantors, and to
              exercise such rights, power and authority, as required for all purposes in connection with this Agreement, including the right to grant consents, exercise waiver rights, make declarations and receive notices and other documentation, in
              accordance with this Agreement, on behalf of the Sellers and the Guarantors. The Sellers’ Representatives shall be relieved from the restrictions under section 181 German Civil Code. This power of attorney shall not terminate in the event of
              the loss of capacity or death or any insolvency event of any of the Sellers or the Guarantors or by the occurrence of any other event but shall remain in full force and effect. The Purchaser shall be entitled to rely on any statement,
              decision or action taken by the Sellers’ Representative on behalf of the Sellers or the Guarantors, and each Seller and each Guarantor shall be bound thereby.

          

     

    	

          	(b)	
            A decision, act or omission, consent or instruction of the Sellers’ Representative constitutes a decision of the relevant Sellers and the relevant Guarantors and is final, binding and conclusive upon the relevant Sellers and the
              Guarantors, and the Purchaser may rely upon any such decision, act or omission, consent or instruction of any Sellers’ Representative as being the decision, act or omission, consent or instruction of the relevant Sellers and the relevant
              Guarantors.

          

     

    
      43

      
        

    

    	

          	(c)	
            In case of a termination of the Sellers’ Representative’s appointment, the Sellers and the Guarantors, acting jointly, shall first notify the Purchaser of such termination, and shall appoint a replacement Sellers’ Representative within 10
              calendar days after such termination. For so long as no such notice of a new Sellers’ Representative has been provided, any notices delivered to the Sellers’ Representative shall be deemed to be validly made to all the Sellers and the
              Guarantors, and the Purchaser may rely fully on all acts of the Sellers’ Representative.

          	(b)

    	18.4	
            Entire Agreement

          

     

    This Agreement contains the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements and understandings (whether written or oral) with
      respect to all or any part of the subject matter of this Agreement (including the letter of intent dated October 7, 2021), except for the NDA. No side agreements to this Agreement exist.

     

    	18.5	
            Amendments, Supplements

          

     

    Any amendment or supplement to or modification of this Agreement (together with all Exhibits hereto) shall be valid only if made in writing, except where a stricter form (e.g., notarization) is required under mandatory Applicable Law. This shall also apply to this Section 18.5.

     

    	18.6	
            Assignments

          

     

    Unless expressly otherwise provided in this Agreement or unless otherwise agreed in writing between the relevant Parties, neither Party may assign, transfer, pledge, encumber, delegate or
      otherwise dispose of any right, obligation or claim they may have under this Agreement without the relevant other Party’s/ies’ prior written consent, provided that the Purchaser may assign any claims it may have under this Agreement other than claims
      for primary performance (außer Ansprüche auf Erfüllung von Hauptleistungspflichten) for security purposes to the banks, financing institutions, bondholders financing and/or other providers of financing the
      Transaction and/or any agent or trustee acting on their behalf. Notwithstanding the preceding sentence, the Purchaser may assign the benefit of this Agreement and/or of any other transaction document to which it is a party, in whole or in part, to,
      and it may be enforced by any Affiliate of the Seller or the Seller’s Guarantor which is or becomes the legal owner (including by way of acquisition, merger, contribution, spin-off, dissolution) from time to time of any or all of the securities or
      the assets of Purchaser, as if such person was the Purchaser under this Agreement.

          	(a)

          	(b)

          	(c)

              unless the right of retention have been acknowledged (anerkannt) in writing by the respective other Party or Parties or have been established by a final decision (rechtskräftig

                festgestellt) of a competent court (Gericht) or competent arbitral tribunal (Schiedsgericht).

          

     

    	18.8

    Except as expressly otherwise provided in this Agreement, this Agreement shall not grant any rights to, and is not intended to operate for, the benefit of the Guarantors (other than under Sections
      16 and 18) or any third parties (kein echter Vertrag zugunsten Dritter) or with protective effect for any third parties (kein Vertrag mit Schutzwirkungen für Dritte).

     

    	18.9	
            No Joint and Several Liability; Joint Exercise of Rights by the Sellers

          

     

    	

          	(a)	
            Except as expressly otherwise provided in this Agreement, (i) no Seller shall be joint and several liable under or in connection with this Agreement (keine Gesamtschuld) but each Seller shall only
              be severally liable (teilschuldnerische Haftung) for any obligation by such Seller under or in connection with this Agreement and (ii) and the Purchaser and the Purchaser’s Guarantor shall not be joint
              and several liable under or in connection with this Agreement (keine Gesamtschuld) but each of the Purchaser and the Purchaser’s Guarantor shall only be severally liable (teilschuldnerische Haftung) for any obligation by such Party under or in connection with this Agreement.

          

     

    	

          	(b)

            Governing Law

          

     

    This Agreement (including any dispute, controversy or claim arising out of or in connection with this Agreement (or any ancillary agreement), or the breach, termination or (in)validity thereof)
      shall be governed by, and construed in accordance with, the substantive laws of Germany, for the avoidance of doubt excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

     

    	18.11	
            Arbitration

          

     

    All disputes arising out of or in connection with this Agreement or its validity shall be finally settled in accordance with the Arbitration Rules of the German Arbitration Institute (DIS) (Deutsche Institution für Schiedsgerichtsbarkeit e.V.) without recourse to the ordinary courts of law. The arbitral tribunal (Schiedsgericht) shall be comprised of three members. The seat of the arbitration is Frankfurt am Main, Germany. The language of the arbitration shall be English; provided that documents submitted as evidence may be submitted in their original
      German language and without an attendant translation. The rules of law applicable to the merits shall be German law.

     

    
      45

      
        

    

    	18.12	
            Severability

          

     

    Should any provision of this Agreement be or become, or be deemed to be or become, invalid, ineffective or unenforceable as a whole or in part, the validity, effectiveness and enforceability of
      the remaining provisions shall not be affected thereby. Any such invalid, ineffective or unenforceable provision shall, to the extent permitted by Applicable Law, be deemed replaced by such valid, effective and enforceable provision as comes closest
      to the economic intent and purpose of such invalid, ineffective or unenforceable provision as regards subject matter, amount, time, place and extent. The same shall apply in the event that this Agreement contains any gaps (Vertragslücken). The Parties are aware of the decision of the Federal Supreme Court (Bundesgerichtshof) of September 24, 2002. However, it is the express intent of the Parties that this
      Section 18.12 shall not be construed as a mere reversal of the burden of proof (Beweislastumkehr) but rather as a contractual exclusion of section 139 of the German Civil Code (BGB) in its entirety.
