Announcement of the terms of the underwriting and the Unused Warrants Option Agreement in connection with the Warrant Program

26 May 2026 07:10 CEST

Oslo, 26 May 2026: Reference is made to the stock exchange announcement
published by the Company earlier today, 26 May 2026, regarding the
commencement of the exercise period for the 67,680,945 warrants issued on ISIN
NO0013711523 in connection with the rights issue and related private placement
(Nw.: frittstående tegningsretter) (the "Warrants").

Each Warrant gives the holder the right to subscribe for one (1) new share in
the Company at an exercise price of NOK 8.2508 (the "Exercise Price"),
representing a 20% discount to the volume-weighted average trading price
(VWAP) quoted on the Oslo Stock Exchange for trades in the shares in the
Company during the period from 8 May 2026 to 22 May 2026.

The exercise period for the Warrants runs from 08:00 hours (CEST) on 26 May
2026 to 16:30 (CEST) on 9 June 2026 (the "Exercise Period"). The total gross
proceeds to the Company if all Warrants are exercised will amount to
approximately NOK 558 million (the "Maximum Warrant Proceeds").

THE UNDERWRITING
In connection with the exercise of the Warrants, the Company has entered into
underwriting agreements (the "Underwriting Agreements") with Pareto Securities
AS (the "Manager") and certain new investors (together with the Manager, the
"Underwriters"). Pursuant to the Underwriting Agreements, the Underwriters
have undertaken, severally and not jointly, to secure minimum gross proceeds
of NOK 150 million in connection with the exercise of Warrants (the "Total
Underwriting Obligation"), representing 26.86% of the Maximum Warrant
Proceeds. The underwriting provided pursuant to the Underwriting Agreements
(the "Underwriting") is subject to a utilisation cap of NOK 300 million (the
"Utilisation Cap"), representing 53.72% of the Maximum Warrant Proceeds. The
extent to which the Underwriting is triggered depends on the Warrant
utilisation, as follows:

a) if Warrants for a total amount in the range between NOK 0 and NOK 150
million (i.e. 0% and 26.86% of the Maximum Warrant Proceeds) have been validly
exercised prior to the expiry of the Exercise Period, then the Underwriting
shall be drawn in full;

b) if Warrants for a total amount in the range between NOK 150 million and the
Utilisation Cap have been validly exercised prior to the expiry of the
Exercise Period, then the Underwriters' commitment shall be reduced on a
linear basis for the amount of Warrant exercise in that interval (i.e. the
Underwriters shall subscribe for new shares for a total amount equal to the
difference between the Utilisation Cap and the amount for which Warrants have
been validly exercised), resulting in proceeds of NOK 300 million from the
Warrants Exercise and Underwriting in total; and

c) if Warrants for a total amount at or above the Utilisation Cap have been
validly exercised prior to the expiry of the Exercise Period, then the
Underwriters shall not be required to subscribe for any shares based on their
Underwriting obligations.

The Underwriting is divided between the Underwriters as follows:

* Pareto Securities AS, NOK 67,000,000
* Fenja Capital I A/S, NOK 25,000,000
* Fredrik Lundgren, NOK 15,000,000
* Wilhelm Risberg, NOK 15,000,000
* Schonfeld Global Master Fund L.P., NOK 13,000,000
* Selandia Alpha Invest A/S, NOK 10,000,000
* Infinitas Investment Group LTD, NOK 5,000,000

The Underwriters will receive an underwriting fee of 9% of their respective
underwriting commitments, payable in cash.

If the Underwriting is triggered, the board of directors (the "Board") intends
to carry out a private placement directed at the Underwriters for subscription
of new shares at a subscription price equal to the Exercise Price as described
above (the "Contemplated Underwriting Private Placement") by use of the board
authorization granted by the Company's annual general meeting held on 8 May
2026 (the "Board Authorisation"). If the Underwriting is triggered, the
Contemplated Underwriting Private Placement will be carried out as soon as
possible after the expiry of the Exercise Period.

The Contemplated Underwriting Private Placement represents a deviation from
the shareholders' preferential rights to subscribe for and be allocated new
shares. The Board has considered this deviation and the Contemplated
Underwriting Private Placement is in line with the equal treatment obligations
under the Norwegian Public Limited Liability Companies Act and the Norwegian
Securities Trading Act. The Board assessed several factors when deciding on
the transaction structure, including inter alia certainty to secure minimum
proceeds of NOK 150 million in relation to the exercise of the Warrants. On
this basis, the Board considers the Contemplated Underwriting Private
Placement to be in the common interest of the Company and its shareholders,
that there are sufficient reasons for deviating from the shareholders'
preferential rights, and that the Contemplated Underwriting Private Placement
is not in breach of applicable rules and regulations for equal treatment.

THE UNUSED WARRANTS OPTION AGREEMENT
The Company has also entered into an unused warrants option agreement (the
"Unused Warrants Option Agreement") with the Underwriters (the "Option
Holders"). Pursuant to the Unused Warrants Option Agreement, each Option
Holder has been granted a right, but not an obligation, to subscribe for new
shares in the Company at the Exercise Price (the "Unused Warrants Option").
The total number of new shares for which the Unused Warrants Option may be
exercised (the "Option Shares") shall be equal to the lower of (i) 67,680,945
(being the total number of Warrants) less (a) the number of Warrants validly
exercised prior to the expiry of the Exercise Period and (b) any shares issued
in the Contemplated Underwriting Private Placement, and (ii) the number of new
shares in the Company that may be listed on the Oslo Stock Exchange without
triggering the requirement for the preparation of a new listing prospectus. If
the Unused Warrants Option is exercised for more Option Shares than available,
allocations shall be made on a pro rata basis among the exercising Option
Holders.

The Unused Warrants Option must be exercised by written notice to Pareto
Securities AS no later than the expiry of the Exercise Period (i.e. 16:30 CEST
on 9 June 2026).

If any Unused Warrants Options are exercised, the Board intends to carry out
another private placement (in addition to the Contemplated Underwriting
Private Placement) directed at the relevant Option Holders for subscription of
new shares at a subscription price equal to the Exercise Price (the
"Contemplated Warrant Option Private Placement") by use of the Board
Authorisation. If Unused Warrants Options are exercised, the Contemplated
Warrant Option Private Placement will be carried out as soon as possible after
the expiry of the Exercise Period.

The Contemplated Warrant Option Private Placement represents a deviation from
the shareholders' preferential rights to subscribe for and be allocated new
shares. The Board has considered this deviation and the Contemplated Warrant
Option Private Placement is in line with the equal treatment obligations under
the Norwegian Public Limited Liability Companies Act and the Norwegian
Securities Trading Act and on this basis, the Board considers the Contemplated
Warrant Option Private Placement to be in the common interest of the Company
and its shareholders, and that there are sufficient reasons for deviating from
the shareholders' preferential rights.
