(b)No later than five (5) Business Days prior to the Closing Date and within three (3) Business Days upon fulfilment or waiver of the last Closing Condition, the Sellers shall procure that the Company provides the Parties with a written statement (the "Estimated Closing Statement") setting forth the (i) Enterprise Value (ii) plus Estimated Closing Cash, (iii) minus Estimated Closing Indebtedness, (iv) minus any liabilities of the Company (whether actual or contingent) that are triggered by, resulting from or otherwise associated with, the transactions contemplated under this Agreement, (v) minus dividends declared or received, (vi) plus/minus the amount, if any, by which the Estimated Net Working Capital exceeds/is less than the Target Net Working Capital, the total of (i) through (vi) multiplied by 90.96% (ninety point ninety six percent) and rounded up or down to the nearest hundredth and (vii) the Estimated Purchase Price resulting therefrom (the "Estimated Purchase Price"), in each case determined in accordance with the Agreed Accounting Principles, together with such schedules and data to support the calculations set forth in the Estimated Closing Statement. A specimen of the Estimated Closing Statement is set out in Exhibit./3.1(b). Furthermore, the Sellers shall provide the Purchasers, no later than (5) Business Days prior to the Closing Date, with a written notice setting forth the allocation of the Estimated Purchase Price, less the Escrow Amount, to each of the Sellers (such written notice also to include a pro-rata allocation of the respective portion of the Estimated Purchase Price to the Acquisition Share 4A and the Acquisition Share 4B).

(c)The Estimated Purchase Price and the Final Purchase Price both are gross purchase prices, each including all Taxes. In particular, the Sellers will not charge the Purchasers any VAT in connection with the sale and transfer of the Acquisition Shares.

(d)In connection with the preparation of the Estimated Closing Statement, the Sellers shall consult in good faith with the Purchasers regarding the amounts and calculations therein and consider in good faith any comments or modifications from the Purchasers. The Sellers shall and shall procure that the Company shall provide the Purchasers and their representatives with reasonable access to all relevant information and personnel of the Company in connection with the preparation of and the Purchasers' review of the Estimated Closing Statement. If the Sellers have complied with their obligations hereunder but the Parties are nevertheless unable to resolve any disagreement with respect to the Estimated Closing Statement, Closing shall not be unduly delayed by the Purchasers and the amounts calculated by the Company in good faith for the Estimated Closing Statement shall be used for the determination of the Estimated Purchase Price.

(a)Upon Closing, the Purchasers shall pay the Estimated Purchase Price, less the Escrow Amount, as allocated to the Sellers in the notification of the Sellers pursuant to Clause 3.1(b), to the Sellers in full in Euro by wire transfer of immediately available funds in cash, free and clear of all fees (other than fees of the recipient's bank), deductions, withholdings and charges to the following bank accounts of the Sellers:

(i)Seller 1: IBAN: [***];

(c)The Parties are in agreement that the remaining amount of the Escrow Amount once due for payment to the Sellers, if any, shall be distributed pro rata exclusively to each Seller 1 – 4 and thus increase only the respective Final Purchase Price of each Seller 1 – 4. Seller 5 shall not receive and has no right to receive any amount from the Escrow Amount.

(a)The Estimated Purchase Price shall be adjusted after Closing as follows (the "Purchase Price Adjustment"):

If the Final Purchase Price based on the Closing Accounts and calculated in accordance with Clause 3.1(a) falls short of or exceeds the Estimated Purchase Price determined in the Estimated Closing Statement in accordance with Clause 3.1(b), then the Estimated Purchase Price shall be reduced or increased, as the case may be, by the full amount of such difference.

(b)Exhibit./1.1(a) contains an example of the calculation of the Purchase Price Adjustments pursuant to Clauses 3.1(a) and 3.3(a) for mere illustrative purposes.

(c)The amount payable based on this Purchase Price Adjustment according to Clause 3.3(a) by the Sellers or the Purchasers shall be a separate payment obligation of either the Sellers or the Purchasers, due and payable, without prejudice to Clause 3.3(d), within twenty (20) Business Days after the Closing Accounts are final and binding on the Parties in accordance with Clause 3.4. Any such payments shall be made (i) if to the Purchasers, to an account specified by the Purchasers in writing for such purpose,

and (ii) if to the Sellers, in such proportion and to such bank accounts as specified in Clause 3.2(a).

(d)If, on the basis of the final and binding Closing Accounts, the Final Purchase Price falls short of the Estimated Purchase Price (such difference, the "Shortfall Amount"), the Purchaser 2 is authorized to instruct, also on behalf of the Sellers and Purchaser 1, the escrow agent under the Escrow Agreement to release from the Escrow Amount and pay to the Purchasers an amount in cash equal to the Shortfall Amount. Such payment releases the Sellers from their payment obligation under Clause 3.3(c) subject to the Escrow Amount being sufficient to cover the Shortfall Amount.

(a)The Closing Accounts shall be prepared as of the end of the Closing Date in accordance with Austrian GAAP and the Agreed Accounting Principles. For the purpose of this Agreement, the sole purpose of the Closing Accounts shall be the computation of the Final Purchase Price (calculated in accordance with the formula set out in Clause 3.1(a) including Exhibit./1.1(a)) and the Purchase Price Adjustment; accordingly, the amounts of the Closing Cash, the Closing Indebtedness and the Closing Net Working Capital shall be derived from the Closing Accounts.

(b)The Purchasers, as the new legal owners of the Company following Closing, shall procure and the Sellers (in particular, those holding management positions in the Company) and the Co-Signor shall support and in any event not obstruct or otherwise hinder, delay or condition, that draft Closing Accounts are prepared and delivered to the Sellers together with the Purchasers' draft calculation of the Purchase Price Adjustment within seventy (70) Business Days after Closing and the Sellers shall procure that all information and support reasonably required by the Company to produce draft Closing Accounts are made available without undue delay.

(c)The Sellers shall jointly notify the Purchasers in writing within thirty (30) Business Days after receipt whether or not the Sellers accept the draft Closing Accounts and the calculation of the Purchase Price Adjustment (such notice in case of non-acceptance an "Objection Notice"). An Objection Notice shall not be made if the amount in dispute in the aggregate (i.e. taking all dispute items together) does not exceed EUR 50,000 (fifty thousand Euro) and shall set out in reasonable detail the Sellers' reasons for such non-acceptance and specify the adjustments which, in the Sellers' opinion, should be made to the draft Closing Accounts or the calculation of the Purchase Price Adjustment in order for it to comply with the requirements of this Agreement. Any item or amount not specifically objected to in the Objection Notice shall become final and binding on the Parties for purposes of this Agreement, except to the extent that an adjustment to a disputed item made in accordance with this Clause 3.4 requires an offsetting adjustment to be made to an undisputed item.

(d)If the Sellers serve an Objection Notice in accordance with Clause 3.4(c), the Purchasers and the Sellers shall use all reasonable efforts to meet and discuss the objections of the Sellers and to agree the adjustments (if any) required to be made to the draft Closing Accounts (and/or Purchasers' draft calculation of the Purchase Price

Adjustment), in each case within fifteen (15) Business Days after receipt by the Purchaser 2 of the Objection Notice.

(e)If the Sellers are satisfied with the draft Closing Accounts (either as originally submitted or after adjustments agreed between the Sellers and the Purchasers pursuant to Clause 3.4(d)) or if the Sellers fail to give a joint Objection Notice within the thirty (30) Business Days period referred to in Clause 3.4(c), then the draft Closing Accounts and calculation of the Purchase Price Adjustment prepared in accordance with this Agreement or after adjustments agreed between the Sellers and the Purchasers pursuant to Clause 3.4(d) shall constitute the final Closing Accounts and Purchase Price Adjustment.

(f)If the Sellers and the Purchasers do not reach agreement within fifteen (15) Business Days of receipt by the Purchaser 2 of the Objection Notice, then the matters in dispute as set out in the Objection Notice (to the extent unresolved) may be referred (on the application of either the Sellers or the Purchasers) for determination by PwC Österreich GmbH Wirtschaftsprüfungsgesellschaft or, if that firm is unable or unwilling to act, by such other independent firm of chartered accountants of international standing as the Sellers and the Purchasers shall agree or, failing agreement, appointed by the President of the Austrian Chamber of Tax Advisors and Auditors (Präsident der Österreichischen Kammer der Steuerberater und Wirtschaftsprüfer) (the "Audit Expert"). The Audit Expert shall be requested to make its decision within thirty-five (35) Business Days (or such later date as the Sellers, the Purchasers and the Audit Expert agree in writing) of confirmation and acknowledgement by the Audit Expert of its appointment and the receipt of the last submission of any Party in accordance with this paragraph. The following provisions shall apply once the Audit Expert has been appointed:

(A)within fifteen (15) Business Days following the acknowledgement by the Audit Expert of its appointment, the Sellers (jointly) and the Purchasers (jointly) shall each prepare a written statement on the matters in dispute which (together with the relevant supporting documents) shall be submitted to the Audit Expert for determination and copied at the same time to the respective other Parties;

(B)following delivery of their respective submissions, the Purchasers (jointly) and the Sellers (jointly) shall each have the opportunity to comment once only on the other's submission by written comment delivered to the Audit Expert not later than ten (10) Business Days after receipt of the other’s submission and, thereafter, neither the Sellers nor the Purchasers shall be entitled to make further statements or submissions except insofar as the Audit Expert so requests (in which case it shall, on each occasion, give the respective other Parties (i.e. the Sellers (jointly) or the Purchasers (jointly), as the case may be) (unless otherwise directed) ten (10) Business Days to respond to any statements or submissions so made). There shall be no material ex parte communication with the Audit Expert;

(C)in giving its determination, the Audit Expert shall state what adjustments (if any) are necessary, solely for the purposes of this Agreement, to the draft Closing Accounts and/or the calculation of the Purchase Price Adjustment in respect of the matters in dispute in order to comply with the requirements of this Agreement and

to determine finally the Closing Accounts, the Final Purchase Price and the Purchase Price Adjustment; for the avoidance of doubt, the Audit Expert (i) shall be bound by the terms and conditions of this Agreement, in particular the Agreed Accounting Principles, and (ii) shall make its determination based solely on the written presentations and supporting materials provided by the Parties and at least one (1) oral hearing (which must be held in the presence of the Parties and their advisors, including by way of video conference) and (iii) may not assign a value to any item (A) greater than the greatest value for such item claimed by either Party (i.e. the Sellers (jointly) or the Purchasers (jointly)) or (B) less than the smallest value for such item claimed by either Party (i.e. the Sellers (jointly) or the Purchasers (jointly)) in each case in such Party's (i.e. the Sellers (jointly) or the Purchasers (jointly)) final submission to the Audit Expert. The Audit Expert shall specify the grounds for its decision with respect to all points of contention between the Sellers and the Purchasers; and

(D)the Audit Expert shall act as an expert (and not as an arbitrator) in making its determination on the basis of this Agreement (in particular the Agreed Accounting Principles) which shall, in the absence of manifest error, be final and binding on the Parties and, without prejudice to any other rights which they may respectively have under this Agreement, the Parties expressly waive, to the extent permitted by law, any rights of recourse they may otherwise have to challenge it.

(g)The Sellers and the Purchasers shall each be responsible for their own costs in connection with the preparation, review and agreement or determination of the Closing Accounts. The fees and expenses of the Audit Expert shall be advanced by the Sellers and the Purchasers in 50/50 proportion, provided that in case of a failure of payment of the share of such advance of the Audit Expert by a Party (i.e. the Sellers or the Purchasers), the other Party (i.e. the Purchasers or the Sellers) may decide in its sole discretion to pay the share of the first mentioned Party to the Audit Expert. Such Party/ies shall be entitled to claim the reimbursement of such advance from the other Party/ies. The Parties shall bear the cost of the Audit Expert in proportion to their respective success and defeat. The Parties shall all be treated as clients (Auftraggeber) within the meaning of the General Terms and Conditions for Auditors 2018 (Allgemeine Auftragsbedingungen für Wirtschaftstreuhandberufe 2018).

(h)To enable the Sellers to meet their obligations under this Clause 3.4, the Purchasers shall provide, and procure that the Company provides, to the Sellers the reasonably necessary access to books, records and other documents of the Company, to the extent legally permitted, to the date that the draft Closing Accounts are agreed or determined.

(i)When the Closing Accounts, the Final Purchase Price and the Purchase Price Adjustment have been agreed or determined in accordance with the preceding provisions of this Clause 3.4, then the Closing Accounts (including the Closing Cash, Closing Indebtedness and Closing Net Working Capital reflected in the Closing Accounts) as well as the Final Purchase Price and the Purchase Price Adjustment shall be final and binding upon the Parties for the purposes of the determination of the Purchase Price Adjustment.

No Party is entitled to exercise any right of retention (Zurückbehaltungsrecht) or set-off (Aufrechnung) in respect of any amount payable by such Party under or pursuant to this Agreement (including the Estimated Purchase Price, the Final Purchase Price, the Purchase Price Adjustment) for or with claims it may have (under this Agreement or otherwise) against the respective other Party/ies and shall not otherwise withhold the proper payment, in full, of any amount payable by such Party/ies to the respective other Party/ies under or pursuant to this Agreement.

Any failure by a Party to make any payment under this Agreement when it is due shall result in the respective Party's (i.e. all Purchasers or all Sellers, as the case may be) immediate default, without any reminder by the other Party/ies being required. In this case, default interest pursuant to Sec 456 of the Austrian Commercial Code (Unternehmensgesetzbuch) shall be payable as from and including the relevant due date until and excluding, the date on which such payment is actually made, without prejudice to any other rights and remedies arising from such failure under this Agreement or applicable law.

If any payments are made after Closing by the Sellers to the Purchasers or are made by the Purchasers to the Sellers, in each case, under this Agreement, the Final Purchase Price shall be deemed to have been decreased if the payments are made by the Sellers to the Purchasers, or increased if the payments are made by the Purchasers to the Sellers, in each case, by an amount equal to such payments.

The completion of the sale of the Acquisition Shares contemplated in this Agreement ("Closing") shall take place at the offices of CERHA HEMPEL Rechtsanwälte GmbH or in such other location as mutually agreed upon by the Parties in writing, on such day as mutually agreed upon by the Parties in writing or, if there is no such agreement, on the first Business Day of the month following the month in which the last Closing Condition has been fulfilled or waived, unless fulfilment or waiver of the last Closing Condition happens less than eight (8) Business Days before such day in which case Closing shall not take place on the first Business Day of the following month but on the first Business Day of the month thereafter, provided however that if the first Business Day of the month thereafter is in December 2023, the Closing shall take place on the first Business Day of January 2024 (such date being the "Closing Date").

All claims asserted against the Sellers for breach of a representation and warranty pursuant to Clause 6 shall be raised by the Purchasers by giving written notice to the Sellers with the basis of such claim and available documents evidencing such claim within forty five (45) Business Days after (i) a Purchaser has become actually aware of the breach of a representation and warranty under this Agreement or (ii) receipt by a Purchaser of a written notice of any claim made or threatened to be made by any third Person which may give rise to a claim hereunder. Failure by the Purchasers to give notice within the period specified above shall exclude or limit

the rights of the Purchasers to make a claim only if and to the extent that such non-compliance has caused or increased the Sellers' liability under this Agreement.

(a)With respect to a breach of a representation and warranty under this Agreement notified by the Purchasers to the Sellers pursuant to Clause 7.1, the Sellers have the opportunity to create, within forty five (45) Business Days after receipt of such notice of breach by the Sellers, at their own expense the position (either in kind or through the payment of an equivalent amount) which would have existed had the respective representation and warranty of the Sellers been true and correct (Verbesserung/Naturalrestitution). If and to the extent the Sellers do not want or are not in the position to perform this kind of remedy, the Purchasers may claim for payment of the monetary compensation in the amount of all damages (whether direct, indirect, incidental or consequential), including, but not limited to, lost profits, interest, fines, Taxes, penalties, costs (including reasonable legal, accounting and other fees and expenses of professional advisors) and other losses (collectively "Damages") which the Purchasers and the Company, respectively, have suffered or incurred and would not have suffered or incurred if the representation and warranty in question had been true and correct.

(a)The Purchasers acknowledge that, other than as expressly provided in Clause 6, the Sellers have not made any guarantee, representation or warranty pertaining to the subject matter of this Agreement and Clauses 6 and 7 contain the exclusive remedies for any kind of claim for a breach of a representation or warranty under Clause 6.

(b)Each of the representations and warranties referred to in Clause 6, shall be construed as a separate one and shall not be otherwise limited or restricted by reference to or inference from the terms of any other representation and warranty except as explicitly stated.

All claims asserted against the Sellers for breach of a representation and warranty under this Agreement shall be time-barred (verjährt) – to avoid that a claim becomes time-barred the Purchasers shall file such claim with the courts competent according to Clause 14(b) of this Agreement before expiration of the term –

(a)in relation to a representation and warranty referred to in Clause 6.14 (Taxes), if a Tax proceeding has not been commenced by a Tax Authority within six (6) years from the Closing Date, but if such Tax proceeding has been commenced within six (6) years from the Closing Date, upon the expiration of six (6) months after the final and formal as well

as materially conclusive assessment of the relevant Taxes (including, if applicable, exhaustion of all extraordinary legal remedies);

(b)in relation to a representation and warranty referred to in Clause 6.1 (Status of the Sellers) or Clause 6.2 (Existence / Ownership of the Acquisition Shares) after five (5) years from the Closing Date;

(c)in relation to a representation and warranty referred to in (A) Clause 6.7 (Intellectual Property) other than Clause 6.7(f) or 6.7(i), or (B) in Clause 6.15 (Litigation and Investigations), after three (3) years from the Closing Date

(d)in relation to (A) a representation and warranty referred to in Clause 6.7(f) or 6.7(i), (B) all other representations and warranties not referred to above in Clauses 7.4(a) to 7.4(c) after two (2) years from the Closing Date;

provided that if a Third Party Claim which could give rise to a claim for breach of a representation or warranty referred to under any of the Clauses 7.4(b) through 7.4(d) is raised within the limitation periods specified in such Clauses, claims against the Sellers for breach of a respective representation and warranty shall be time-barred (verjährt) upon the expiration of six (6) months after the final and formal resolution of the respective Third Party Claim (including, if applicable, exhaustion of all extraordinary legal remedies).

The Purchasers shall not be entitled to multiple recovery, including in the event any circumstances constitute a breach of more than one representation and warranty or result in an indemnity claim under Clauses 10 or 11.

This Clause 7 shall not restrict or limit the obligation of the Purchasers to mitigate any loss or damage which they may suffer in consequence of a breach of a representation and warranty of the Sellers under this Agreement in accordance with applicable law.

(a)The Purchasers shall not be entitled to be paid any sum in respect of a claim for a breach of a representation and warranty pursuant to Clause 6 unless (i) such claim towards the Sellers exceeds on a stand-alone basis the amount of EUR 30,000.00 (thirty thousand Euros) (the "Qualifying Claim") and (ii) the liability of the Sellers to Purchasers in respect of such Qualifying Claim exceeds when aggregated with the aggregated liability of the Sellers hereunder in respect of all other Qualifying Claims, the sum of EUR 150,000.00 (one hundred fifty thousand Euros) (the "Threshold"), in which case the entire amount and not only the excess amount shall be payable.

(b)Subject to Clause 7.7(c), the total liability of the Sellers for a breach of a representation and warranty pursuant to Clause 6 in the aggregate shall not exceed an amount of 35% (thirty five percent) of the Final Purchase Price received by each individual Seller, except that in respect of a breach of the representations and warranties given in Clause 6.1 (Status of the Sellers) and Clause 6.2 (Existence / Ownership of the Acquisition Shares)

For the avoidance of doubt, even if the joint and several liability (Clause 1.4) applies, under the foregoing sentence the aggregate amount of liability for each individual Seller shall not exceed the caps set out above.

(c)The total liability of the Seller 5 for a breach of a representation and warranty (i) given in Clause 6.1 (Status of the Sellers) and Clause 6.2 (Existence / Ownership of the Acquisition Shares) shall not exceed an amount of 100% (one hundred percent) of the Final Purchase Price received by Seller 5, and (ii) given in Clauses 6.3 through 6.19 shall be limited to the Escrow Amount held in escrow on the escrow account subject to and in accordance with the Escrow Agreement.

(b)The Purchasers shall, and shall procure that the Company, assist and cooperate with the Sellers, acting reasonably, in relation to the handling of any Third Party Claim. In particular, the Purchasers (i) shall, and shall, subject to applicable law, procure that the

Company, provide the Sellers without undue delay with all information available for the defence of Third Party Claims and regularly update any information relating to Third Party Claims; (ii) provided that the Sellers have unconditionally assumed in writing towards the Purchasers their liability in full under this Agreement for any loss or liability for the Company or the Purchasers under or in connection with a Third Party Claim, shall obtain the prior written approval of the Sellers for any admission, waiver, acknowledgement, compromise, agreement, withdrawal of action or settlements regarding Third Party Claims; and (iii) shall, and shall, subject to applicable law, procure that the Company, allow the Sellers' legal counsel to participate in any proceedings, audits, meetings or other hearings relating to Third Party Claims at any time (or inform the Sellers as reasonably practical of any outcome of meetings or discussions if the Sellers were not present).
