Remedies

In the event of a breach ( Verletzung ) of any of the Sellers’ Warranties (a “ Breach ”), the Sellers shall jointly and severally and in any case fully ( vollumf ä nglich ), within thirty (30) days after a Sellers’ Representative received a notification regarding such a Breach and the estimated Damage from the Purchaser (“ Breach Notice ”), put the Purchaser or, at the election of Purchaser, the Company in the position in which the Purchaser or the Company would have been in had no such breach of a Sellers’ Warranty occurred (restitution in kind; Naturalrestitution ). If the breach results from the existence of a liability, then the Purchaser’s right to request restitution in kind shall include the right to full indemnification from such liability.

If and to the extent Sellers fail to remedy such a Breach in accordance with para (a) above, or if this is not possible or reasonable, Purchaser shall be entitled to seek monetary damage compensation ( Schadenersatz in Geld ) instead of restitution in kind according to Section 5.1.1(a) at Purchaser’s sole discretion, to the Purchaser or the Company. If restitution in kind is fully impossible, then such monetary damages shall replace the remedy of restitution in kind.

If and to the extent that the Sellers fail to provide the requested restitution in

kind within ninety (90) days after the Sellers’ Representative received the Breach Notice, the Purchaser, in its absolute discretion, in whole or in part and in lieu of its right to demand restitution in kind, shall have the right to request the payment of monetary damages to itself or, at the election of the Purchaser, to the Company in such amount as would be necessary to achieve the same effect as a restitution in kind. Until full performance by the Sellers, the Purchaser may freely modify its request.

Scope of and Limitations on Liability

The monetary damage compensation, if any, shall cover damages within the meaning of §§ 249 et seq. BGB, including foreseeable consequential or indirect damages (for the avoidance of doubt including lost profits ( entgangener Gewinn ) and reasonable advisors fees), but excluding (i) internal administration, (ii) other overhead costs and expenses of the Purchaser and (iii) unforeseeable consequential or unforeseeable indirect damages.

The Sellers shall have no obligation to pay any monetary damage compensation under Section 5.1.1 unless (i) the amount of an individual Claim (or the aggregate amount of several Claims arising from the same event or the same circumstances) exceeds EUR 15,000.00 (fifteen thousand Euros) (the “ Qualifying Claim ”) and (ii) the aggregate amount of the Qualifying Claims of the Purchaser exceeds EUR 35,000.00 (thirty five thousand Euros) (the “ Threshold ”), in which case the Purchaser shall be entitled to recover the entire amount ( Freigrenze ). For the avoidance of doubt, the determination of the amount of a Claim for the purpose of this Section shall be made on the basis of the Claim actually asserted by Purchaser and shall not be deemed limited by the monetary limits set forth herein or a pro-rata or several liability. The Qualifying Claim and Threshold shall not apply to the Sellers’ Fundamental Warranties and, for the avoidance of doubt, breaches of Sections 11.2 (Confidentiality) and 11.9 (Non-compete and non-solicitation) of this Agreement.

The Sellers’ aggregate liability for a Breach shall not exceed the amount of EUR 1,000,000.00 (in words: one million Euros) (the “ Cap ”). This limitation shall not apply in the event of a breach of any of the Sellers’ Fundamental Warranties and, for the avoidance of doubt, for breaches of Sections 11.2 (Confidentiality) and 11.9 (Non-compete and non-solicitation) of this Agreement.

The Sellers’ liability in respect of any breach of any of the Sellers’ Warranties shall be excluded or reduced, as the case may be, if, and to the extent that:

the matter to which the Claim relates is specifically reflected as a

liability ( Verbindlichkeit ), provision ( Rückstellung ), depreciation ( Abschreibung ) or individual write off ( Einzelwertabschreibung ) in the Financial Statements; or

the Purchaser shall have caused ( verursacht oder mitverursacht ) or aggravated the Breach or any damage resulting from such breach or failed to use their commercially reasonable efforts to mitigate the Damage in respect of such breach in each case by a gross negligent or wilful act; or

the Purchaser has actually recovered from any third party, including but not limited to, an insurer, any sum in respect of any matter to which a Claim made relates (all duly documented costs and expenses incurred in making such recovery (including reasonable attorney’s fees) deducted).

Section 377 HGB and Section 442 para. 1 BGB shall not apply.

The Sellers shall not be liable for the incorrectness of a Sellers’ Warranty (other than the Sellers’ Fundamental Warranties) if and to the extent the facts underlying such an incorrectness have been disclosed in Schedules or Exhibits to the relevant Sections of Schedule 4.1a) or fairly disclosed in documents and matters which were made available or disclosed in the Data Room. Any facts, matters or circumstances shall be deemed “ fairly disclosed ”, if the disclosure was made in a manner enabling the Purchaser (applying the care of a prudent business person ( Sorgfalt eines ordentlichen Kaufmanns )) to appreciate the significance of the respective information disclosed on the face of the respective document, including the impact of such disclosure to the Sellers’ Warranties. The Purchaser hereby declares that the Purchaser is not positively aware ( positive Kenntnis ) of any possible incorrectness of any of the Sellers’ Warranties as of today.

The limitations set forth in this Section 5.1.2 shall not apply in the event of wrongful deceit ( arglistige T ä uschung ) or other intentional breaches of contract ( vors ä tzliche Vertragsverletzung ).
