4. Grace Periods, Failure to Fulfil, Compensation

4.1   Any potential deadlines issued by Feri for the delivery of services are considered nonbinding unless an obligation thereto is expressly agreed to in writing.

4.2   Should the client establish a reasonable grace period for Feri after a deadline for delivery of service has passed, and Feri exceeds this extension of deadline or fails to deliver at all, the client retains the right to withdraw from the contract and, if Feri is at fault, to claim compensation for damages instead of the contracted services. Paragraphs 281 and 323 of federal law remain unaffected by this clause.

4.3   Force majeure events, general supply chain complications, business disruptions, and other operational disturbances not caused by or related to Feri as well as their consequences release Feri from contractual performance obligations for the duration of the disruption and to the extent of their repercussions. In case of such events, Feri will furthermore be held harmless from consummating any contractual obligation under exclusion of indemnification.

4.4   Exceptions to the content of an analysis, an appraisal, another product, or an invoice must be specifically documented and immediately reported, at the latest within four weeks of receipt. If no objections are raised within this period of time, all analyses, appraisals, and other products or invoices are confirmed as valid.

4.5   The client can settle outstanding accounts against Feri only when such receivables are uncontested or established as legally valid.

5. Supplementary Performance

5.1   Feri's warranty (to provide supplemental performance) covers only those analyses, appraisals, and other products that are expressly delineated in the contract and delivered to the client, as described in section 2.1.

5.2   Feri's obligation to fulfill its warranty is primarily limited to supplementary performance within a reasonable period. If Feri fails to perform, i.e. never delivers, delivers something unacceptable to the client, refuses delivery without notice, or delays delivery without compensation, the client has the right to choose either to reduce remuneration or to extend the rescission of the contract.

5.3   The claim to supplementary performance must be made by the client immediately in writing.

5.4   The client must accord Feri by conservative measure the required time and opportunity needed to provide supplemental performance. If the client declines to provide this, Feri is released from its obligation to provide supplemental performance.

5.5   The warranty period is limited to one year from the transfer of risk, i.e., from the receipt of services performed.
