must be returned to us immediately.

§ 4 Costs and payment
(1) Unless agreed in writing, our prices apply as ex works and do not include packaging and the additional applicable amount of
value-added tax. Costs of the packing are charged separately.
(2) The payment of the purchasing price is to be made exclusively to the account specified on the invoice.
(3) Unless agreed, and/or as stated in the offer the purchase price is due within 14 days starting from invoice date without
deductions. The relevant date for meeting this deadline shall be considered as the date of receipt of payment by us.
Default interest shall be calculated at 8% above the respective basic interest rate per annum. The right to assertion for higher
amounts of default compensation remains reserved.

§ 5 Offsetting and retention rights
(1) The buyer is entitled to offsetting and retention rights only if its counterclaims are validly determined or undisputed.
The buyer can only be entitled to exercise a right of retention if the counterclaims are based on the same contractual
relationship.

§ 6 Delivery time
(1) The start of the delivery time as indicated by us is dependent on the buyer’s timely and due fulfilment of his contractual
obligations. We reserve the right to raise an objection to non-fulfilment of the contract.
(2) If the buyer fails to accept the goods or culpably breaches duties of cooperation, we will be entitled to demand the refund of
the losses incurred to this extent, including any additional expenses. Further claims remain reserved. If the above pre-requisites
exist, the danger of accidental loss or deterioration of the goods will pass to the buyer for the time in which the acceptance or
payment of the latter are delayed.
(3) Further legal claims and rights of the buyer due to delayed delivery remain unaffected.

§ 7 Transfer of risks on shipment
(1) If the goods are sent to the buyer at the buyer’s request, the risk of accidental loss or accidental deterioration of the goods shall
pass to the buyer upon dispatch to the latter, at the latest upon leaving our warehousing facilities. This applies irrespective of
whether the shipment occurs from the place of delivery or who bears the freight costs.

§ 8 Retention of title
(1) We reserve the ownership rights till the complete payment of the delivered goods according to the delivery contract.
This also applies to all future shipments, even if we do not make explicit reference thereto. We are entitled to take the purchase
goods back, if the buyer acts in violation of the contract.
(2) The buyer is obliged to treat the goods purchased carefully, till the ownership is not transferred to him. In particular he is
obligated, at his own expense, to affect a replacement value insurance against theft, fire and water damages. If maintenance
and inspection work has to be carried out, the buyer shall proceed accordingly in good time and at his own costs. Till the
transfer of ownership, the buyer has to inform us immediately in writing, if the delivered goods have been seized or subjected
to other interventions by a third party. If the third party is unable to reimburse for the losses, the buyer is liable to cover the
court and out of court costs of a lawsuit in accordance with § 771 ZPO.
(3) The buyer is entitled to resell the reserved goods in normal business transactions. The debts of the buyer from the further sale
of the retained goods are already relinquished to us in the amount of the final billing amount agreed with us (including value
added tax). This transfer applies irrespective of whether the goods were resold without or after processing. The buyer remains
responsible for the collection of the debt after such transfer. Our authority to claim remains unaffected by it. We will not,
however, exercise our claims, as long as the buyer fulfils its payment obligations as agreed, does not delay payments and in
particular is not the subject of insolvency proceedings and does not discontinue payments.
(4) The processing, manipulation or alteration of the goods occurs in our name and by our order. In this case, the contingent right
of the buyer to the purchased good shall continue with the transformed item. If the purchased goods are inseparably merged
with other goods not belonging to us, we will acquire co-ownership of the new items in the ratio of the objective value of our
goods with the other goods at the time of merging. The same applies to the case of a mixture. If the mixing occurs in such way
that the goods belonging to the buyer are considered as the main component, the buyer shall be deemed to have already
transferred to the seller, a pro rata share in the title of new goods and shall store the goods the share of the seller therein on
behalf of the seller. To safeguard our claim against the buyer, the buyer also transfers such claims to us, which arise for the
buyer as a result of the incorporation of the goods in real property; we hereby accept this assignment.
(5) We are obliged to release the security held by us on demand of the buyer, providing that the realizable security value exceeds
the amount to be secured by more than 20%.

§ 9 Guarantee and notice of defects and recourse
(1) The warranty rights of the buyer require that he duly examine the goods and notify the defects in accordance with § 377 HGB.
(2) Claims for defects are null and void in 12 months after delivery of the goods to the buyer by us (reference: in case of sale of
used goods the guarantee period can be excluded completely). The above provisions do not apply, if the law in accordance with
§ 438 Para. 1 No. 2 (Structures and material for structures), § 479 paragraph 1 BGB (right of recourse) and § 634a paragraph 1 of
the German Civil Code (construction defects) specifies longer time-limits. Our consent must be obtained prior to any return of
goods.
(3) If, despite all care taken, the delivered goods exhibit a defect, that already existed at the time of transfer of risk, we will, at our
choice, either repair the goods or supply replacement goods, provided that the notice of defects was given in due time. We
must be given an opportunity to correct the defects within a reasonable period. Recourse claims shall remain unaffected by the
above regulation without restriction.
(4) If our repair or replacement fails to correct the defects, buyer shall be entitled to either withdraw the contract or reduce the
compensation.
(5) Defect claims do not apply if there is only a minor deviation from the agreed nature of the goods or only a minor impairment of
usability, if there are natural wear or tear and if defects that occur due to inappropriate or negligent handling, excessive use,
use of unsuitable equipment and facilities, of defective construction works or arising due to other impacts, which are not part of
the contract. If the buyer or a third party has carried out improper modifications or repair work, claims of defects for these and
for consequences incurred do not exist.
(6) Claims by the buyer on account of the required expenditure , in particular for transportation, road costs, labours costs and cost
of materials, as far as the expenditures are increased, because the object of delivery has been forwarded afterwards to another
place other than the buyer’s establishment, unless, the transfer would correspond to its designated use.
(7) Recourse claims of the buyer against us are valid only if the buyer has not has not entered into specific agreements beyond the
legal claims for defects. Furthermore, as for the scope of the buyer’s right of recourse against the seller, paragraph 6 applies
accordingly.
(8) In the case of fraudulent concealment of a defect or in the case of the acceptance of a warranty for the condition of the goods
at the time of the transfer of risk according to § 444 BGB (the seller’s declaration that the object of purchase has a certain
property during the transfer of risk and that the seller, independent of negligence, is prepared to take responsibility for all
consequences of his defects) the buyer’s rights lie solely in accordance with legal regulations.
(9) Damage claims, in case of defects, against the seller are excluded.

§ 10 Other
(1) This contract and all legal relations between the parties are subject to the rights of the Federal Republic of Germany under the
exclusion of UN purchasing law (CISG).
(4) Place of delivery and exclusive area of jurisdiction and for all disputes, according to this contract, is our registered place of
business, unless stated otherwise.
(5) Alterations and additions to this contract must be made in writing. This also applies to changes to this written form. Additional
oral agreements have not been made.
(6) Should any individual provisions of this contract be or become invalid or contain any loopholes, all other terms shall remain
unaffected. A so-called safeguarding clause (the parties undertake to adopt a legal regulation that comes closest to the
economic purpose of the invalid regulation and/or which closes this loophole) should not be negotiated in AGB terms, but
rather as a separate agreement.

claims.

immediately. The third party shall be liable for any costs incurred by us in this regard. If they are not able to fulfil our claims, the
buyer will be liable.

rights or copyrights, the buyer shall give us an immediate written notice. In such case we shall reserve any defence and out-of-court
measures to pursue our rights. The buyer shall support us here.

jurisdiction.

10. Partial inefficacy

respects. Sellers and buyers are obligated in such a case, to replace an ineffective term by an effective one, which comes closest to
the economic purpose of the invalid one.
