2.5 If one or more provisions in these General Terms and Conditions are null and void or nullified, the remaining provisions of these General Terms and Conditions will continue to apply. The Client and the Service Provider will agree on new provisions to replace the null and void provisions, taking into account the purpose and purport of the original provisions as much as possible.

3.3 Agreements to which the Service Provider is a party will be presumed to have been concluded:

7.2 If the parties agree that the Agreement will be amended or supplemented, this may affect the time at which the Agreement’s performance is completed. The Service Provider will inform the Client of any such change in the completion time as soon as possible.

8.10 Small defects that can be properly repaired during the defects liability period cannot constitute grounds for withholding approval, provided that they do not prevent the work from being taken into use.
8.11 The Service Provider will be entitled to complete the work in parts, unless this provision is deviated from by Agreement or unless such partial completion has no independent value.
9.1 The Service Provider should be enabled to verify any complaints submitted and it should be offered the opportunity to repair any faults in the performance or the supply. The Client will, however, remain obliged to pay for the work performed and the goods purchased.

9.7 If a timely complaint is submitted and if the Service Provider finds such complaint to be well-founded, the Service Provider shall, at its discretion, supply new goods or repair the defects, or will take the goods back in return for a credit entry of the purchase price in favour of the Client.
9.8 If it has become impossible or pointless to perform repairs, the Service Provider will be liable only within the limits of the Articles ‘Liability’ and ‘Warranty’.
complaints in respect of work performed
9.9 The Client should communicate to the Service Provider any complaints pertaining to performances delivered verbally and in writing immediately during such performance or, if this is not possible, in writing within eight days of the relevant performance. The notice of default should specify the defect in as much detail as possible, so as to enable the Service Provider to respond adequately.
9.10 If a complaint is well-founded, the Service Provider will perform the services agreed as yet (or have others do so), unless such performance has now become demonstrably pointless to the Client. In that case, the Client should notify the Service Provider thereof in writing.
9.11 If it is no longer possible or has become pointless to perform the agreed activities as yet, the Service Provider’s liability will be limited in accordance with the provisions laid down below under the headings ‘Liability’ and ‘Warranty’

The user will be entitled to demand the advance payment of all or part of the amount due, as a down payment. Only after such advance payment has been made will the user commence its performance of the work.
11.2 If the Client fails to effect payment within the agreed period of time, the Client will be in default by operation of law. In that event, the Client will owe the Service Provider interest at a 1.5% rate per month or part of a month, unless the statutory interest rate or the statutory commercial interest rate is higher, in which case the highest interest rate will apply. The interest on the payable amount will be calculated from the time that the Client defaults to the time of full payment of the amount due.
11.3 If the Client is liquidated, is declared bankrupt or its bankruptcy is filed for, is admitted to statutory composition pursuant to the Dutch Natural Persons Composition Act [Wet schuldsanering natuurlijke personen], is placed under guardianship, dies, attachment is levied against it or is granted a suspension of payments, provisionally or otherwise, the user’s claims vis-à-vis the Client will become immediately due and payable.

12.2 If the user has incurred higher costs which were reasonably necessary, those costs will also qualify for compensation. Court costs and enforcement costs will also be borne by the Client.
13.1 The Client relinquishes its right to the Service Provider to claim deductions from and/or settlement of payments of all obligations in the Agreement.
13.2 The Service Provider will be entitled to suspend performance of its obligations or to dissolve the Agreement in the following events:
- the Client fails to perform the obligations ensuing from the Agreement or fails to perform them in good time or in full;
- circumstances of which the Service Provider has learned following the Agreement’s conclusion give it good reason to fear that the Client will not perform its obligations, or will not perform them on time or in full; if there is good reason to fear that the Client will only perform its obligations in part or will not perform them properly, suspension will be permitted only insofar as this is justified by the relevant failure;
- upon the Agreement’s conclusion, the Client was requested to provide security for the performance of its obligations arising from that Agreement and such security was not provided or is insufficient. As soon as security has been provided, the right to suspend performance will lapse, unless the performance has been unreasonably delayed as a result.
13.3 In addition, the Service Provider may dissolve the Agreement or have it dissolved if circumstances arise of such a nature that performance of the Agreement is impossible or can no longer be required pursuant to standards of fairness and reasonableness, or if any other circumstances arise of such a nature that continued unamended maintenance of the Agreement can no longer reasonably be expected.

14.2 For purposes of these General Terms and Conditions, the term ‘force majeure’ will cover - in addition to its definition in law and legal precedent – all external causes, foreseen or otherwise, which the Service Provider is unable to influence, but as a result of which the Service Provider is unable to fulfil its obligations.
