Information about changes in the CDTi European sales organization

Following the press release on November 12 by Clean Diesel Technology Inc. (CDTi) and its partner Pirelli to voluntary dissolve their joint venture Eco Emission Enterprise (E3), see attached, CDTi has decided to resume the operations in Europe in a similar manner as conducted prior to the joint venture.

This means for us here at CDTi Sweden AB (before Unikat AB and Engine Control Systems) that we will resume selling products direct to distributors, OEM’s and the end customer effective Monday, 25 November, 2013.

For you, as our customer or distributor, it will mean that orders should be placed to CDTi Sweden direct. We CDTi will then confirm the order and ship the goods as before from our storage in Malmö, Sweden to the delivery address you have requested. The invoice will be issued from CDTI and paid to the CDTi bank account as before.

There will be no changes to your prices, payment conditions etc.

As you can understand this change will require us to transfer a number of orders already placed from E3 to CDTi. I hope that this doesn’t cause you too many problems. When this is done we will inform you separately and also send you a new order confirmation.

From now on any request, enquiry, support for products sold by E3 shall be addressed to CDTi Sweden.

Please, continue to pay all outstanding invoices to the E3 account as you have been paying up until now.

If you have any further questions or concerns please don’t hesitate to contact us.

Best regards and look forward to a continued good cooperation.
