15.3 The Customer shall be notified of such changes by e-mail at least 30 calendar days before the planned entry into force of the changes, provided that the adjustment is accompanied by a restriction in the usability of previously generated data or other not only insignificant disadvantages (e.g. adjustment effort).

17.2 In the case of property damage and financial loss caused by other negligence, the Provider and its vicarious agents shall only be liable in the event of a breach of a material contractual obligation, but the amount of liability shall be limited to the damage foreseeable at the time of the conclusion of the contract and typical for the contract; material contractual obligations are those whose fulfillment characterizes the contract and on which the Customer may rely (hereinafter referred to as "cardinal obligation").

17.3 Notwithstanding the provision in Section 17.1, the Provider's liability in the event of a slightly or normally negligent breach of a cardinal obligation proven by the Customer for all damage events falling within the same contractual year shall be limited in terms of amount in accordance with the following provision:

17.4 Liability for damages without fault for defects which were already present at the time of conclusion of the contract shall be excluded.

17.5 Subject to the provisions of Section 17.1, the Provider shall not be liable for the loss of Customer data if the damage is due to the Customer's failure to perform data backups in accordance with Section 10.3 and thereby to ensure that lost Customer data can be restored with reasonable effort.

17.6 The above limitations of liability shall also apply in the event of fault on the part of a vicarious agent of the Provider as well as to the personal liability of the Provider's employees, representatives and bodies.

17.7 For telecommunication services the limitations of liability according to § 44a TKG remain unaffected.

17.8 Insofar as the Service is provided free of charge, the Provider assumes no liability for damages resulting from the use of the Service, except in cases of gross negligence or intent.

If it is not terminated by the end of a contractual year, the contract shall be extended by a further 12 months in each case. Termination of the individual order shall also include termination of the user account and, if applicable, of all users provided for end customers of the customer as of the next possible date. All other agreements of the contractual relationship in

connection with the individual order and these usage agreements, in particular the SLA, shall be deemed terminated at the same time. The GCU shall end at the same time, but not as long as Customer Data is still within the Provider's sphere of influence (see 14.3).

18.3 The right of the parties to terminate for good cause without notice shall remain unaffected. Good cause shall be deemed to exist if one party grossly violates the obligations expressly regulated in these Terms of Use and the entire contractual relationship, and in particular if

f.) the other party has agreed to agreements for the satisfaction of third party creditor claims in connection with payment difficulties.

18.4 Good cause entitling the Provider to terminate the Agreement without notice shall also be deemed to exist if the Customer is in default with the payment of the remuneration or a not insignificant part of the remuneration pursuant to Section 12 for two consecutive months, or is in default with the payment of the remuneration in a period extending over more than two months in an amount equal to the remuneration for the last two months prior to the notice of termination. In the event of extraordinary termination for which the Customer is responsible, the Provider may demand immediate lump-sum compensation in the amount of 50% of the monthly basic fee remaining until the end of the regular contract term. The Customer reserves the right to prove a lower damage, the Provider the right to prove a higher damage.

Upon Customer's request, Provider shall support Customer in this regard against remuneration.

19.2 In the event of termination of the Individual Order, the Provider shall endeavor to support the Customer as best as possible in the changeover to another service provider against remuneration. The parties shall agree on details in a separate migration agreement.

20.2 The place of performance and exclusive place of jurisdiction for all disputes arising from or in connection with the contractual relationship shall be Munich.

20.3 Should individual provisions of these General Terms and Conditions be invalid, this shall not affect the validity of the remaining provisions.

The above provision shall apply mutatis mutandis in the event of loopholes.
