Losses thereunder, provided that the foregoing sentence shall not apply to the extent the Losses result in a substantial increase of the premiums payable in
respect of any such policy as a result of any such claim.

10.5.2    Neither the Seller nor any other member of the Seller's Group shall be liable for any Losses if and to the extent:

1. the Losses are included as a liability in the Working Capital Statement;
2. the Losses result from an act or omission of the Purchaser or any other member of the Purchaser's Group outside the ordinary
course of business of the Purchaser or such member of the Purchaser's Group, as the case may be; or
3. the Losses result from the failure by the Purchaser to ensure that all reasonable actions necessary or appropriate are taken to
prevent or mitigate any Losses that could give rise to a claim; or

actions of any Governmental Authority not in force on Closing Date, or any change in case law after Closing, any change in corporate structure, tax structure

the Group or any other member of the Purchaser's Group (in whole or in part) in respect of the Loss which is the subject matter of the claim, the Seller, in its
sole discretion, may require that the Purchaser shall procure that all reasonable steps are taken to enforce such recovery and shall, or shall procure that the

pay to the Seller as soon as practicable after receipt an amount equal to (a) any sum
recovered from the third party less any costs and expenses reasonably incurred in obtaining such recovery or, if less, (b) the amount previously paid by the
Seller to the Purchaser.

10.6.2    The Purchaser shall consult with the Seller in good faith with regard to the enforcement by the
Purchaser of any recovery from a third party described in Clause 10.6.1.

than the amount that the Seller paid to discharge the claim as a result of the Purchaser's failure to take reasonable steps under Clause 10.6.1, then the Seller
shall be entitled to claim from the Purchaser the additional amount that the Seller can reasonably demonstrate would have been reasonably recoverable were
Purchaser to have taken such reasonable steps.

10.7    Mitigation of
Losses

10.7.1    The Purchaser shall procure that all reasonable steps are taken to avoid or mitigate any Losses which in the absence of
mitigation might give rise to a liability in respect of any claim under this Agreement.

third party which indemnifies or compensates the Purchaser with respect to any amount paid by the Seller in discharge of any claim under this Agreement
than the Purchaser would have recovered in the absence of such commercial or other interests and (b) settling a third-party claim at a higher amount than the
Purchaser would have settled such claim in the absence of such commercial or other interests. For the avoidance of doubt, the foregoing does not exempt
the Purchaser from its obligation to show evidence of the amount of Losses actually resulting from a breach of the relevant Seller's Warranty in accordance
with Dutch law.

The provisions of Clause 10.2, 10.3 and 10.4 shall not apply to any claim:

10.8.1    based on fraud (bedrog, as defined in Article 3:44 of the Netherlands Civil Code) or the knowing concealment of material
information by the Seller; or

incurred by the Purchaser as a result of a claim under this Agreement in excess of the Escrow Amount, with a view to reflecting that STAK shall not bear
(directly or indirectly) any part of each such Loss. In view of the foregoing, the Seller, the Seller Shareholders and the Individual Shareholders shall be
severally and jointly, as co-principal debtors (hoofdelijk aansprakelijk), liable to STAK, as an irrevocable third party stipulation (onherroepelijk
derdenbeding), for 4,4% (four point four per cent) of:

11.1

If the Purchaser or any other member of the Purchaser's Group becomes aware of any matter or
circumstance that may give rise to a claim (other than the existence of any patent or patent application) against the Seller under this Agreement (including if
any third party gives notice to the Purchaser or any other member of the Purchaser's Group with respect to any matter that does or may give rise to a claim
by the Purchaser vis-à-vis the Seller or any other member of the Seller's Group), then the Purchaser shall within a reasonable period of time deliver a
notice to the Seller setting out such information as is available to the Purchaser or any other member of the Purchaser's Group as is reasonably necessary to
enable the Seller to assess the merits of the claim.  Failure to give such notice shall not affect the rights of the Purchaser, except to the extent that the Seller
is prejudiced by such failure, in which case the amount of the Seller's liability for the claim shall be reduced to the extent of such prejudice.

11.2    Notification of
claims

Without prejudice to what is provided in Clauses 10.1 and 11.1, notices of claims under this Agreement shall be given by the
Purchaser to the Seller within the time limits specified in Clause 10.1, specifying information of the legal and factual basis of the claim and the evidence on
which the Purchaser relies and, if practicable, an estimate of the amount of Losses which are, or are to be, the subject of the claim (including any Losses
which are contingent on the occurrence of any future event).

Schedule 6 Reporting accountants

1

1.1    The Reporting Accountants shall be engaged jointly by the Seller and the Purchaser on the terms set out in this Paragraph 1
and otherwise on such terms as shall be agreed, provided that neither the Seller nor the Purchaser shall unreasonably refuse their agreement to terms
proposed by the Reporting Accountants or by the Purchaser or the Seller, as the case may be. If the terms of engagement of the Reporting Accountants have
not been settled within forty-five (45) Business Days of their identity having been determined (or such longer period as the Seller and the Purchaser may
agree) then, unless the Seller or the Purchaser unreasonably refuse agreement to those terms, those accountants shall be deemed never to have become

1.2    Except to the extent that the Seller and the Purchaser mutually agree otherwise, the Reporting Accountants shall determine their
own procedure and shall make their determination as soon as reasonably practicable and, with respect to the determination pursuant to Clause 5.3.3(c), the
Reporting Accountants:

1. apart from procedural matters and as otherwise set out in this Agreement, shall determine only whether any of the arguments for
an alteration to the draft Working Capital Statement put forward in the notice referred to in Clause 5.3 is correct with respect to the application of the
agreed accounting principles referred to in Clause 5.2 in whole or in part; and if so, what alterations should be made to Working Capital Statement in
order to correct the relevant inaccuracy in it;
2. shall apply the principles set out in Clause 5.2.

1.3    The procedures of the Reporting Accountants shall:

1. give the Seller and the Purchaser a reasonable opportunity to make written representations to them;
2. require that each of the Seller and the Purchaser supply the other with a copy of any written representations at the same time as
they are made to the Reporting Accountants; and
3. permit each Party to be present while oral submissions are being made to the Reporting Accountants.
