Under no circumstances do these include delays caused by acts of God or other events beyond the control and influence of the provider.The latter is to be assumed e.g. whenever the provider, in order to manufacture or to deliver the contractually agreed goods, is dependent on receiving goods or services from a third party and a delay is caused by the provider not receiving these goods or services from the third party on time. The provider does not assume the risk of procurement. If agreed delivery times or not met for reasons beyond the control of the provider, the provider shall inform the customer immediately and shall inform him at the same time about the new estimated delivery time.

This also applies to programs which are given to the customer on the basis of warranty agreements or maintenance contracts. The customer is obliged to inform the provider of the test results immediately after completion of the tests. If the provider does not receive any test results from the customer within a period of 5 weeks after delivery, the software is deemed to be tested and free of defects.
7.3 With regard to the software, the customer shall take appropriate precautions in the event that the software does not work properly in whole or in part (e.g. by data backup, documentation of software use, fault diagnosis, regular checking of the results, emergency planning).

9.3 The customer is required to inform the business partner with whom he plans to enter into a contractual commitment prior to the contract conclusion and in written form that the title to the goods is still retained by the provider. A copy of this notification is to be sent to provider immediately.
9.4 A physical disposal of the goods prior to the fulfillment of the payment obligations can only be made once a written confirmation from the provider to do so is obtained. This confirmation can be granted by the provider upon conclusion of the contract.
9.5 In a case in which the physical disposal of the goods is made by the customer prior to the complete fulfillment of his payment obligations, i.e. thus for goods to which the provider still retains the title of ownership, the following regulations apply irrespective of whether the disposal was granted by the provider or not.
Is the disposal made
a) by merging, mixing or processing the goods according to §§ 946-950 BGB, the provider will receive co-ownership in these new products to the value which is based on the relation of the goods to the goods with which these are merged, mixed or processed. § 947 Abs. 2 BGB is not affected whenever the goods of the provider are the main component in the new product;
b) by selling or transferring the goods or the new products according to clause 5 a), the customer is required to waive all rights and claims arising from the sale in favor of the provider in writing within seven days if applicable. This shall be accepted by the provider. An additional waiver will not become necessary.
c) by a different disposal of these goods for which the customer is still required to waive all rights and claims arising from the underlying exchange transactions in favor of the provider in writing within seven days if applicable and where the goods are concerned. This shall be accepted by the provider. An additional waiver will not become necessary.
9.6 In cases as described in clause 5 b), the provider is required to release the rights and claims transferred to him when requested by the customer for cases in which the realized value of this collateral exceeds the amount due from the customer by more than 10%. The provider will decide which part of the collateral he will release.
9.7 In cases as described in clause 5 a), the customer has the right for a retransfer of ownership towards the provider, and in cases as described in clause 5 b) and c), the customer is owed the right for the reassignment of these claims, provided all payment obligations of the customer towards the provider have been met completely.
9.8 In cases of seizures or other interventions by third parties, the customer is obliged to inform the provider immediately thus the provider can object according to § 771 ZPO.

§10 Material Defects, Rights of the Customer in Cases of Material Defects
10.1 All information regarding the properties of the goods that the customer receives from the provider via sales catalogues, price lists or other promotion documents, are under no circumstances to be considered sourcing agreements or warranties. Agreements of this kind need to be made between the contract partners expressly in writing.
10.2 The software is in the agreed state and is suitable for the contractually assumed use for standard application without further agreement. The software has the quality that is to be expected of this type of software, however it is not without flaws. Limitations, in regard to the functionality of the program which may arise from hardware defects, environmental conditions, operating errors and similar cases, are not a flaw. A minor reduction of the quality will not be taken into account.
10.3 Furthermore, the provider will not assume any responsibility
a) for defects of the goods that arise from product descriptions and specifications of the customer
b) for any defectiveness of the goods when the due purchase price has not been paid by the due date
c) for any parts, materials or other pieces of equipment which were manufactured by the customer or which were commissioned by the customer
d) for any product defects which may arise due to incorrect installation, assembly or use, faulty use, negligence or other reasons relating to the environment of the customer, including third parties commissioned by the customer
e) for reduced functionality or system failures which are outside the control of the provider, e.g. failures in the mobile data networks, interruptions of connections of any kind
f) the listed exemptions from liability do not apply in such cases in which defects are due to ill intent or gross negligence by the provider.
10.4 Legal rights accruing from defects can only be claimed by the customer if the goods are immediately checked for defects upon delivery, and the provider is informed not later than two weeks after the delivery by receiving a written report from the customer in which all defects are described in detail. If defects are not recognizable at the time of delivery, these are to be reported in writing once they are detected.
10.5 Reporting defects does not equal the assertion of any claims due to defects unless the customer clearly states such when reporting the defects. Otherwise an additional written statement is needed from the customer for the assertion of specific claims due to defective goods.
10.6 When defects are reported, the provider retains the right to examine the incriminated goods. For this reason and at his own option, he can request the customer to provide him with access to the goods at their current location or have the goods send back to his business premises, for which the provider will bear the incurred cost. If the examination of the goods by the provider show that the goods are not defective and that such could have been noticed by the customer, the provider has the right to request the customer to reimburse him for any cost incurred, especially for transport or for the shipping and handling of the goods.
10.7 If the delivered goods are inadequate, the provider may choose if he either wants to perform a subsequent fulfillment to eliminate any defects (rectification) or if he wants to make a new shipment of non-defective goods (replacement delivery). The right of refusal of the provider for a subsequent fulfillment remains unaffected in accordance with the legal requirements. The provider has the right to make the owed subsequent fulfillment dependent on the payment of the customer for the goods, however the customer has the right to retain a partial payment of the balance due which is in relation to the defective parts.
10.8 The customer is required to allow for an opportunity and an appropriate period of time until which the provider may perform the subsequent fulfillment. Goods that have been replaced by the provider are to be sent back to the provider if this is requested by him. Subsequent fulfillments do not include the installation or the removal of incriminated parts. The cost for installation or removal will be charged to the customer.
10.9 Additionally, defects in regard to the software are to be reported in writing in such a manner that these error symptoms are described comprehensively and, if applicable, that these are proven by written records, hard copies and other methods that help to illustrated the defects. The notice of defects needs to illustrate how the listed defects can be reproduced. The possibility to reproduce such defects is a requirement for the acceptance of any claims.In cases of material defects in regard to the software, the provider has the right for a subsequent fulfillment based on the following regulations: the subsequent fulfillment to remove the defects is handled by the provider at his own option or by supplying a software that is free of these defects or by showing the customer how to avoid any negative impacts these defects may cause. In cases of defect software, at least three attempts to rectify these defects are to be accepted by the customer. Furthermore, the customer is expected to accept a newer and comparable version of the program or a comparable prior version of the program without the defects in cases in which this is reasonable. The provider has the right to reject rectification measures if these are not economical sensible or manageable. In these cases, the customer may cancel the contract.
10.10 The customer will support the provider during the failure analysis and during attempts to rectify the defects by describing any problems clearly, by informing the provider in an extensive manner and by allowing for the necessary time and opportunity needed by the provider in order to remove the defects. The provider may handle the removal of the defects at his own option either at the premises of the customer or via remote analysis. The customer is required to provide the technical requirements and further, to allow for access to the software upon receiving a request by the provider to do so. For this, the customer will bear any incurred cost.
10.11 The contract partners agree on the following defect classes and reaction times:
a) Defect Class 1: Operation-impending defects/ the defect prevents the use of the goods or of the software: the defect prevents the use at the customer; no workaround is available: the provider immediately begins with the removal of the defects and continues these activities vehemently even beyond the regular business hours (working days between 08:00 a.m. and 05:00 p.m.).
b) Defect Class 2: Non-critical operating defects: the defect impedes operations at the customer extensively / the defect impedes the usage of the goods: the use of the software at the customer can be realized when using a workaround or with temporary limitations or difficulties: upon receiving a timely notification, the provider shall begin with the removal of any such defects on the same day if reasonable, or, if the notification is received with a delay, at the beginning of the next working day. The provider shall continue his efforts during the regular working hours. The provider may offer a temporary workaround initially, and remove the defects at a later date if this is reasonable for the customer.
c) Defect Class 3: Miscellaneous defects: the provider shall remove the defects with his next regular program update if this is reasonable for the customer.
10.12 The period of limitation for any claims of the customer due to defects is three months. The period starts with the supply of the goods to the customer. The legally mandated statute of limitation is valid for claims that are due to faulty goods or are due to intent or deception by the provider or as far as the provider has assumed a guarantee.
§11 Limitation of Liability and Claims for Damages
11.1 If not stated to the contrary in the terms and conditions (including further regulations), the provider shall be liable for any violations to these contractual and non-contractual duties in accordance with the legal regulations.
11.2 The provider is liable for any claims – independent of the legal basis – on the basis of the encumbrance liability for intent and gross negligence. For simple negligence, the provider is only liable (and hereby with reservations in view to mitigating factors that may arise from the standard of liability in accordance with the legal regulations, e.g. due care for own affairs) fora) claims arising from loss of life, bodily injury or harmfulness to health b) for claims arising from a substantial violation to a central contractual duty (i.e. a duty whose fulfillment is in itself the basis for a proper implementation of the contract and for which the contract partner can regularly expect a compliance); in such cases, any claims for compensation are limited to the foreseeable and typically encountered damages but not more than 10% of the order value per claim and 5% of the order value for all claims arising from and in connection with the contract as a whole.c) The limitation of liability as stated in clause 2 is also valid for a breach of duty by or respectively for a group of persons for whose violations the provider is liable in accordance with the valid legal regulations. They are not applicable if the provider has maliciously hidden a defect or has assumed a guarantee for the condition of these goods and for any claims of the customer in accordance with the product liability laws.
11.3 The limitation of liability according to clause 2 as stated above, are also applicable in meaning for the reimbursement of costs and provisions.
§12 Additional Rights and Duties of the Customer
12.1 The customer is only allowed to offset due payments if his claim is uncontested and has been decided in a legally binding manner. The counter-claim is only uncontested or is decided legally binding, if both contract partners shall arrive at an agreement in regard to the reason and the amount. This can only be assumed once the counter-claim as been confirmed by the provider in writing to at least the amount that is to be offset. Additional legal requirements for offsetting payments are not affected.
12.2 The customer may only transfer any rights arising from the contractual agreement if the provider has given written consent. Any request for transfer needs to be send by the customer to the provider immediately and in writing. If a transfer of rights is made without the prior consent of the provider, the non-established or rejected request will be viewed as a prohibition of assignment agreement between the contract partners. § 354a HGB will remain unaffected.
12.3 The customer must not initiate any measures or have these initiated by a third party which may violate the rights of intellectual property as they are used by the provider in connection with the goods. In particular, any brand names or other distinctive features which are imprinted on or which are attached to the goods of the provider must not be concealed, or changed, or removed by the customer.
12.4 If the customer wants to further process the goods, especially in order to create new products, the customer will give the provider the assurance that the new products will not violate the commercial trademarks of any third party. The customer will indemnify the provider against any possible liability that may arise from any such violations and assumes all fees the provider may incur in such a case in which he will need to defend himself against claims resulting from a violation.
§13 Confidentiality and Data Protection
13.1 The contract partners are contractually committed to keeping items to which they will be given access to prior and during the fulfillment of the contract by their respective contractual partner (such as e.g. software, documents, information regarding prices and sales terms and which are legally protected and / or contain business and trade secrets or which are designated as confidential) confidential at all times and beyond the term of the contract, unless these are already made public without any violation to the agreement of confidentiality. Each contract partner will store these items in such a manner that safeguards against any access of a third party. Should the customer violate his duty of confidentiality, he is liable to pay damages in the amount of 10 % of the order value with the customer but at least EUR 10,000 to the provider for each case of breach of duty as contractual penalty in accordance with § 13 while simultaneously waiving any legal right for an objection to the continuation of offense. The contractual penalty is hereby defined by reasonable discretion. For this, relevant factors are the importance of the violation of duty, the negative impact for the provider (including any intangible negative impacts) and the degree of violation and fault of the customer. In cases in which the contract partners do not arrive at an agreement, the decision of an arbitrator i.e. a judge of the Higher Regional Court of Düsseldorf as appointed by the president of this Higher Regional Court shall be legally binding once both contract partners have given their statements (a written statement will suffice).
13.2 The customer will grant access to the contractual items only to those employees and any additional third party who, in order to perform their operational duties, and must have access to these. He will instruct these persons accordingly about the classified nature of these items.
13.3 The provider shall process the data of the customer as necessary for the fulfillment of the business processes according to the regulations for data protection. The provider may name the customer as a reference customer once his duties have been successfully completed.
The customer is committed towards the provider to inform his customers in regard to the tracking and the collection of vehicle information if the customer should choose to use this function. The provider is committed to deleting the date in accordance with the regulations for data protection, the legal requirements or when demanded by the customer. The customer is informed that all data on the IT systems of the provider is stored at a European computer center. Deviating locations for data storage are to be agreed upon taking into account the costs incurred in each case.
§14 Other Contractual Clauses
14.1 These terms and conditions and any contracts which are in reference to them, shall be governed by guidelines and regulations of the German law. Except where these terms and conditions constitute deviating agreements, the legal regulations are applicable. Not applicable are the guidelines and regulations of the UN conventions for the international sale of goods (CISG).
14.2 The place of jurisdiction for disputes arising from these terms and conditions and for contracts which are in reference to them, is the city of Wuppertal. The provider has the right to file suit to the court at the seat of the customer.
14.3 Any deviation to the terms and conditions for contracts that are in reference to them can only be made, if the both contract partners agree to them expressly, mutually and in writing. If the deviations are defined during the conclusion of the contract and not subsequently, these become only applicable if they are expressly stated in the order confirmation of the provider. The aforementioned regulations are also applicable if the written from requirement is waived.
14.4 Should individual clauses of the terms and conditions become invalid or unenforceable or should they become invalid or unenforceable once a contract is concluded, this shall not affect any other contractual aspects of this contract. In such a case, the invalid or unenforceable clause shall be substituted by a valid and enforceable clause which shall be effective in a manner which most closely reflects the economic objective intended by both contract partners in regard to the clause which has become invalid or unenforceable.
