Update on Type Approval in the UK draft Certificate of Acceptance received

Wavetrain Systems AS (Wavetrain), a subsidiary of Nordic Technology Group AS
(NTG), has for some time had an application process for Type Approval from
Network Rail in UK for Wavetrain Overlay Miniature Stoplight Crossing (OMSL)
system. The OMSL system integrates Wavetrain's previously product-accepted
Level Crossing Warning System (LCWS), based on acoustic train detection, with
Miniature Stop Lights and audible warning devices to provide clear visual and
audible warnings to users when unsafe to cross.

Following the completion of an independent review according to Common Safety
Method Risk Evaluation and Assessment (CSM-RA), Network Rail has provided
Wavetrain a draft version of the Certificate of Acceptance. Furthermore,
Network Rail has informed Wavetrain that an executed version of the
Certificate is expected to be issued soon. The draft states that the
Certificate authorises a monitored operational trial of a single-track
configuration at Colliery footpath level crossing, leading to full operation
for public use.

While receipt of the draft Certificate is a significant milestone, the
Certificate of Acceptance is not formally granted until signed and issued by
Network Rail.

Wavetrain Systems meets strict safety requirements, can be delivered at
competitive cost, and can be fully installed in hours.

In addition to the UK, Wavetrain has received strong interest and is in active
customer processes with national railway companies in several countries,
including Ireland, Austria, Sweden and Australia.

Upon receipt of the executed Certificate of Acceptance from Network Rail, NTG
will provide more details in an updated stock exchange release.
