  • The Customer acknowledges that before entering into an agreement for the purchase of any Goods from CDTEK LTD he has expressly represented and warranted that he is not insolvent and has not committed any act of bankruptcy, or, being a company with limited or unlimited liability, knows of no circumstances which would entitle any debenture holder or secured creditor to appoint a receiver, administrative receiver, or liquidator, to petition for winding-up of the company or exercise any other rights over or against the company’s assets.
  • Goods, the subject of any agreement by CDTEK LTD to sell, (which by expression means, without limitation, any Order) shall be at the risk of the Customer as soon as they leave the premises of CDTEK LTD or that of a nominated supplier, and the Customer shall insure such Goods against loss and damage naming CDTEK LTD as loss payee and shall produce to CDTEK LTD evidence of such insurance on request.
  • Such Goods shall remain the sole and absolute property of CDTEK LTD as legal and equitable owner until such time as the Customer shall have paid to CDTEK LTD the agreed price together with interest due and with the full price of any other Goods the subject of any other contract with CDTEK LTD, and CDTEK LTD may reclaim such Goods as soon as the payment for them becomes overdue, without having to rescind the contract with the Customer.

5. CARRIAGE AND DELIVERY

  • CDTEK LTD reserves the right to charge carriage on deliveries as appropriate.

  • No liability for direct or consequential loss or damage arising from delay in delivery of the Goods, including without prejudice to the generality of the foregoing any delays due to an Act of God, war, civil disturbance, strikes, lock-outs, or any act outside CDTEK LTD’s control, will be accepted.

The submission of a claim within this time limit does not necessarily mean that CDTEK LTD will accept liability in relation to such claim.
