Invoiced amounts are to be paid in full within 14 days of invoice issue unless otherwise agreed in writing.  Determining for the date of the payment is receipt by OhmEx GmbH. Cheques first apply as payment upon clearing.  If the customer fails to issue payment by the deadline, the outstanding amount is subject to an interest of 5% p.a. from the payment deadline.

The right to assert higher interest and further damages in the event of default hereby remains unaffected.

IV. Retention of title

4.1. The following retention of title serves to secure all currently existing and future accounts receivable of OhmEx GmbH against the customer from the delivery and service contract existing between the parties.

4.2. The goods delivered by OhmEx GmbH to the customer remain the property of OhmEx GmbH until payment in full of all secured demands. The goods and quasi goods under the terms of this clause subject to retention of title are hereinafter called reserved goods.

4.3. The customer stores the reserved goods without charge on behalf of OhmEx GmbH.

4.4. OhmEx GmbH reserves ownership and rights to be granted until full payment of the owed amount. Prior to this rights are always only temporary and may be revoked at the discretion of OhmEx GmbH at any time.

4.5 In the event of a breach of duty by the customer, in particular in the event of delayed payment, OhmEx GmbH also has the right without setting a deadline to demand the surrender of the delivered goods and/or to withdraw from the contract; the customer is obligated to surrender the goods. The demand to surrender the goods does not represent a declaration of withdrawal on the part of OhmEx GmbH unless this expressly declares a withdrawal from the contract.

4.6. In the event of delayed payment on the part of the purchaser OhmEx GmbH has the right to claim back the goods; the customer is obligated to surrender these. The customer already here permits OhmEx GmbH to enter his premises and offices.

4.7. If the reserved goods are processed by the customer, it is agreed that the processing occurs on behalf of and to the account of OhmEx GmbH as manufacturer and that OhmEx GmbH directly assumes co-ownership if the processing occurs with the goods of several owners or the value of the processed item is higher than the value of the reserved goods to the new product. In the event that no such ownership acquisition should occur at OhmEx GmbH, the customer hereby assigns his future ownership or co-ownership to the newly created product to OhmEx GmbH as security.  If the reserved goods are combined with other goods to a unified object or inseparably mixed and one of the other items is to be viewed as the main item, OhmEx GmbH hereby assigns, if the main items is its property, the customer the co-ownership of the combined items at the relationship as described in line 1.

4.8. In the event of a re-sale of the reserved goods the customer hereby assigns as security the account receivable arising from this against the purchaser to OhmEx GmbH. OhmEx hereby accepts this assignment. The same applies to any other demands that replace the reserved goods or arise regarding the reserved goods, such as insurance claims or claims arising for unauthorised actions or loss or destruction.  OhmEx GmbH revocably entitles the customer to collect the accounts receivable assigned to OhmEx GmbH in its own name. OhmEx GmbH may only revoke this right to collect in the event of an enforcement event.

4.9. If a third party should acquire the reserved goods, particularly through seizure, the customer shall immediately report the ownership of OhmEx GmbH and inform OhmEx GmbH in order that this can assert its ownership rights. In the event that the third party should not be in a position to reimburse OhmEx GmbH for court and legal fees arising in this conjunction, the customer shall be liable herefor.

4.10. If OhmEx GmbH should withdraw from the contract on the grounds of a breach of contract (enforcement event) on the part of the customer, in particular in the event of a default of payment, this has the right to demand the return of the reserved goods. Further rights such as compensation for use etc. hereby remain unaffected.

4.11. Upon the occurrence of problems with payment, cessation of payment, knowledge of applications for insolvency proceedings, opening of preliminary insolvency proceedings or the issue of an affidavit or a court or out of court settlement the right to further processing, use or instalment of the reserved goods hereby expires.


V. Deadlines for deliveries and delay

5.1. Deadlines and dates provided by OhmEx GmbH for deliveries and services always only apply as approximations unless a fixed deadline or date is expressly promised or agreed.

The customer shall not acknowledge the infringement of rights alleged by the third party and shall leave all disputes to either OhmEx GmbH or only conduct these with the approval of OhmEx GmbH.

8.6 The customer shall report complaints with a comprehensible description of the fault symptoms in writing and where possible under the provision of written records, hard copy or other documents illustrating the defect.


IX. Guarantee, material defects

9.1. The guarantee term is 18 months following delivery, however 12 months at the most following initial operation. The date of the initial operation is to be reported in writing to OhmEx GmbH.

9.2. If the performance is defective and does not only insignificantly impair its contractual use, OhmEx GmbH initially has the right to perform repairs or a new delivery (subsequent performance). If the customer has set OhmEx GmbH a reasonable deadline upon first request and OhmEx GmbH refuses subsequent performance or this fails, the customer reserves the right regarding the rectification of defects either to rescind the contract or to demand a discount.  In the event of an insignificant deviation that does not impair the function the customer may only demand a discount.

9.3. If OhmEx GmbH after the reporting of a fault has performed services but no material defect exists and the customer should have recognised this, the customer shall assume all arising costs.  By the invoicing of the costs the respective invoice rates for services from OhmEx GmbH shall be based on the respective applicable list prices.

9.4. Liability for material defects expire as such for services provided by OhmEx GmbH in which the customer modifies or intervenes with the performance unless the customer proves that the intervention did not cause the defect.  Liability for material defects shall also expire if the customer after recognising the defect does not report this without delay to OhmEx GmbH or the performance is not used under the contractually agreed conditions corresponding to the documentation.

9.5. A legal defect of the contractual performance is given when the rights required for the contractually intended purpose have not been sufficiently granted. In the event of legal defects OhmEx GmbH provide assurance that it shall create a legally defect-free possibility of use for the contractual performance or will take back the performance subject to the contract with the deduction of a reasonable compensation for use at the discretion of OhmEx GmbH. The latter is only permitted if a remedial action is not reasonable for OhmEx GmbH.

9.6. Customer claims for expenses for the purpose of subsequent performance, particularly transport, work and material costs are hereby excluded, insofar as the costs are increased due to the subject of the performance being subsequently relocated to a site other than the place of performance.

9.7. The customer is entitled to guarantee claims against OhmEx GmbH for one year from acceptance of the respective performance. This restriction does not apply to claims to compensation that arise on the grounds of a breach of claims to subsequent performance by defect by OhmEx GmbH. Claims to damage that are on the grounds of a rejected subsequent performance may only be asserted during the statutory period of limitation if the claim to subsequent performance is asserted by the customer within the shortened term for claims to material defects.

9.8. The provisions of clause IX apply to all claims to damages.

9.9. OhmEx assumes no liability for damage through corrosion.


X. Industrial property rights and copyrights

10.1. Insofar as a third party asserts claims against a third party on the grounds of an infringement of an industrial property right or copyright (hereinafter protected rights) by a product supplied by OhmEx GmbH and used for the contractual purpose, OhmEx GmbH is liable to the customer as follows:

a) OhmEx GmbH shall at its discretion and at its expense either obtain rights of use for the product, modify the product so that protected rights are not infringed or exchange the product. If this is not possible for OhmEx GmbH under reasonable conditions, it shall take back the product against refunding of the purchase price.

b) The aforementioned obligations on the part of OhmEx GmbH only exist when the customer informs OhmEx GmbH regarding claims asserted by a third party in writing and without delay, does not acknowledge an infringement and reserves all defence measures and settlement claims to OhmEx GmbH. If the customer should cease use of the product for limitation of damage or other important grounds he is obligated to inform the third party that the ceasing of use does not represent any acknowledgement of an infringement.

10.2. Claims on the part of the customer are excluded insofar as he is responsible for the infringement of protected rights.

10.3. Claims on the part of the customer are furthermore excluded insofar as the infringement of protected rights is based on special instructions of the customer, through an application not foreseeable by OhmEx GmbH or is caused in that the customer modifies the product or using this together with a product not supplied by OhmEx GmbH.

10.4. Further claims against OhmEx GmbH are hereby excluded; the agreements to liability remain however equally unaffected as the right of the customer to withdraw from the contract.


XI. Liability for compensation on the grounds of culpability

11.3. Any declaration on the part of OhmEx GmbH (e.g. in service specifications, product descriptions etc.) expressly does not represent a guarantee declaration. A guarantee is only then to be assumed if an express and written declaration is issued and the subject and content of the guarantee is specified.  From a guarantee declaration OhmEx GmbH is only liable to compensation if this is expressly assumed in the guarantee. This liability is by soft negligence limited to the limitations in clause 11.2.

11.4. To claims to compensation for expenditure and other liability claims against OhmEx GmbH clauses 11.1. to 11.3. apply correspondingly. This limitation does not apply to claims to damages that are on the grounds of a breach of the duty to provide subsequent performance on the part of OhmEx GmbH. Claims to damages on the grounds of a rejected subsequent performance may only be asserted during the term of the statute of limitation if the claim to subsequent performance is asserted by the customer within the shortened term for material defects.

11.5.Insofar as OhmEx GmbH provides technical information or acts as an adviser and this information does not belong to the contractually agreed performance, this is free of charge and subject to the exclusion of all liability.


XII. Export

The contracting parties shall also impose this obligation on their employees and any involved third parties.

14.2. Insofar as one of the contracting parties is hindered through force majeure in fulfilling its contractual duties, this is not considered a breach of contract and the deadlines set in or in conjunction with the contract shall be extended correspondingly. The same applies, insofar as OhmEx GmbH is reliant of third party advance performance and this is delayed on the grounds of force majeure.

14.3. Each party shall make every effort to undertake that which is necessary and reasonable to limit the extent of the consequences that are caused through force majeure.  The contracting party affected by force majeure shall inform the other party in writing without delay of the beginning and the end of the obstruction.
