1. Validity

1.1 The following terms and conditions of business apply for all our orders and contracts concerning deliveries and services that a contractual partner is to provide to us or for us. They are the sole valid contract conditions and take precedence over other provisions in so far as we have not ourselves specified or confirmed such provisions in writing. The terms and conditions of business of the contractual partner have no validity.

1.2 For work on buildings (construction works in the sense of §1 VOB/A), the General Contractual Conditions for the Execution of Construction Works (Allgemeinen Vertragsbedingungen für die Ausführung von Bauleistungen = VOB/B DIN 1961) apply in so far as these terms and conditions of business do not specify some other provision.

1.3 Otherwise, the legal relationship between us and the contractual partner is subject to the law of the Federal Republic of Germany. The regulations contained in the UN Convention on Contracts for the International Sale of Goods of 11th. April 1980 do not apply unless they correspond to our terms and conditions
