Det vises til børsmelding fra DOF ASA ("DOF" fortsatt diskusjonen for å enes om alternative løsninger for å gjennomføre Restruktureringen for det tilfelle at den ekstraordinære generalforsamlingen i DOF ikke godkjenner vedtakene som kreves for å gjennomføre Restruktureringen. Som et resultat av ovennevnte diskusjoner har partene i Restruktureringsavtalen i dag inngått en tilleggsavtale til Restruktureringsavtalen (""Tilleggsavtalen""). Partene har der blitt enige om de konkrete tiltak som vil bli iverksatt av kreditorene for å kunne gjennomføre Restruktureringen med forbehold om oppfyllelse eller fritak av visse standardbetingelser. For det tilfelle at den ekstraordinære generalforsamlingen i DOF stemmer ned de vedtak som kreves for å kunne gjennomføre Restruktureringen er DOF i henhold til vilkårene i Tilleggsavtalen forpliktet til å åpne rekonstruksjonsforhandlinger etter rekonstruksjonsloven av 7. mai 2020 og foreslå en rekonstruksjon med følgende nøkkelelementer: (i) en del av DOFs direkte finansielle gjeld vil bli konvertert til egenkapital; og (ii) ingen andre forpliktelser for DOF eller Gruppen vil bli påvirket av rekonstruksjonen. Alle andre elementer av Restruktureringen vil bli iverksatt etter at rekonstruksjonen er gjennomført. Gjennomføringen av rekonstruksjonsforslaget vil kreve at en ny ekstraordinær generalforsamling i DOF godkjenner forslaget med minst 50 % av aksjene representert på generalforsamlingen. Dersom Restruktureringen gjennomføres ved en rekonstruksjon vil de eksisterende aksjene i DOF representere 1 % av de fullt utvannede aksjene i DOF etter ferdigstillelse med mindre annet blir avtalt mellom Gruppens kreditorer. Til sammenligning vil de eksisterende aksjonærene representere 4 % av de fullt utvannede aksjene i DOF dersom Restruktureringsavtalen blir vedtatt som foreslått på første ekstraordinære generalforsamling. Dersom rekonstruksjonsforslaget ikke kan gjennomføres enten fordi nødvendig flertall på den andre ekstraordinære generalforsamlingen ikke oppnås eller av andre grunner vil det bli åpnet konkursbehandling i DOF. I henhold til Tilleggsavtalen har kreditorene i Gruppen avtalt å etablere et nytt selskap (""Newco"") som vil gi et tilbud om å overta hele Gruppens virksomhet fra konkursboet gjennom et oppkjøp direkte eller indirekte av datterselskapene mot at deres krav mot DOF blir underordnet. Det vil ikke bli tilbudt kontantvederlag. Dersom et slikt tilbud aksepteres vil Newco bli det nye morselskapet i Gruppen og det vil bli søkt om notering av aksjene til Newco på Oslo Børs eller Euronext Expand Oslo. Dersom Restruktureringen gjennomføres etter en konkurs i DOF vil eksisterende aksjonærer i DOF ikke motta noen egenkapitalandel i den restrukturerte gruppen. Styret og ledelsen i DOF er overbevist om at det er i aksjonærenes interesse at Restruktureringen gjennomføres på et frivillig grunnlag og at aksjonærene vil oppnå best mulig resultat ved å støtte Restruktureringen på den ekstraordinære generalforsamlingen i DOF. Dersom en frivillig løsning ikke oppnås må styret imidlertid ta hensyn til kreditorenes interesser som Gruppens viktigste økonomiske interessenter samt søke å sikre videre drift av Gruppens virksomhet til fordel for sine kunder ansatte og andre interessenter. Styret er av den oppfatning at gjennomføringen av Restruktureringen gjennom de alternative gjennomføringsstegene som er avtalt i Tilleggsavtalen vil være det beste alternativet for DOF og konsernet dersom aksjonærene ikke støtter restruktureringen på den ekstraordinære generalforsamlingen. Alle alternativene ovenfor inkludert formell konkurs i morselskapet DOF ASA for å kunne gjennomføre Restruktureringen er strukturert for å unngå negative konsekvenser for den løpende driften av Gruppen og for å unngå tap for Gruppens kunder leverandører og andre handelskreditorer. Følgelig er ingen andre kreditorer enn de finansielle kreditorene forutsatt å bli berørt av slike alternative implementeringer av Restruktureringsavtalen.

Reference is made to the announcement made by DOF ASA ("DOF" as set out in the announcement on 22 June 2022 engaged in good faith discussions to agree alternative steps to implement the Restructuring in the event that the extraordinary general meeting of DOF does not pass the resolutions required to implement the Restructuring. Following such discussions the parties to the Restructuring Agreement have today entered into an addendum to the Restructuring Agreement (the ""Addendum"") detailing the steps that will be taken by the creditors subject to satisfaction or waiver of certain customary conditions to implement the Restructuring in such event. In the event that the extraordinary general meeting of DOF rejects the resolutions required to implement the Restructuring DOF shall subject to the terms of the Addendum procure that reconstruction proceedings are opened under the Norwegian Reconstruction Act of 7 May 2020 and propose a reconstruction with the following key elements: (i) a portion of DOF's direct financial indebtedness will be converted into equity; and (ii) no other liabilities of DOF or the Group will be affected by the reconstruction. All other elements of the Restructuring will be implemented following completion of the reconstruction. Implementation of the reconstruction proposal will require that an additional extraordinary general meeting of DOF approves the proposal with at least 50% of the shares represented at the general meeting. If the Restructuring is implemented by way of a reconstruction the existing shares in DOF will represent 1% of the fully diluted shares in DOF post completion unless otherwise agreed among the Group's creditors compared to 4% of the fully diluted shares in DOF if the Restructuring Agreement is adopted as proposed in the first extraordinary general meeting. If the reconstruction proposal cannot be implemented either because the required majority at the second extraordinary general meeting is not obtained or for other reasons bankruptcy proceedings will be opened in DOF. Pursuant to the Addendum the creditors of the Group have agreed to establish a new company (""Newco"") that will make an offer to acquire the entire business of the Group from the bankruptcy estate through an acquisition directly or indirectly of its subsidiaries against a subordination of their claims against DOF. No cash consideration will be offered. If such offer is successful Newco will become the new parent company in the Group and an application will be made for the listing of the shares of Newco on Oslo Børs or Euronext Expand Oslo. If the Restructuring is implemented following a bankruptcy in DOF the existing shareholders in DOF will not retain any equity interest in the restructured group. The board of directors and management of DOF firmly believe that it is in the best interest of DOF's shareholders that the Restructuring is implemented on a consensual basis and that the shareholders will obtain the best recovery by supporting the Restructuring at the extraordinary general meeting of DOF. However if a consensual solution is not possible the board of directors must have regard to the interest of its creditors as the main economic stakeholders of the Group as well as seeking to secure the continued operations of the business of the Group to the benefit of its customers employees and other stakeholders. To this end the board of directors is of the opinion that the implementation of the Restructuring through the alternative implementation steps agreed in the Addendum will be the best option available to DOF and the Group if the shareholders do not support the Restructuring at the extraordinary general meeting. All scenarios above including in case of a formal bankruptcy in the parent company DOF ASA to effect the Restructuring are structured to avoid any interruption to the ongoing operations of the Group and to avoid losses for the Group's customers suppliers and other trade creditors. Consequently no other creditors than the financial creditors are envisaged to be affected by such alternative implementations of the Restructuring Agreement.
