DOF ASA and DOF Subsea AS are pleased to announce that each of the companies have agreed to further extend the principal and interest suspension agreements with, or received extensions of similar concessions from, secured lenders representing in total 91% of the secured debt of DOF ASA and DOF Rederi AS and in total 95% of the secured debt of companies within the DOF Subsea AS group (excluding DOF Subsea Brasil Servicos Ltda.) until 31 May 2022. Reference is further made to the previous announcement on 12 April 2022 regarding summons to bondholders' meetings in DOFSUB07 (ISIN NO0010971005), DOFSUB08 (ISIN NO0010788177) and DOFSUB09 (ISIN NO0010836810) in which DOF Subsea AS requested an extension of the standstill period for the three bonds initially until 31 May 2022 and with the possibility to extend to 30 September 2022 with the approval of an ad-hoc committee of bondholders. DOF Subsea AS is pleased to announce that the bondholders' meetings were held today and the proposed resolution received 100%, 92,53% and 100% of the votes in DOFSUB07, DOFSUB08, and DOFSUB09, respectively.

DOF ASA AND DOF SUBSEA AS: FURTHER EXTENSION OF STANDSTILL AGREEMENTS WITH SECURED LENDERS AND RESULT FROM BONDHOLDERS' MEETINGS

April 29, 2022

Reference is made to the resolutions adopted in the bondholders' meetings in DOF Subsea AS' three bond loans (FRN DOF Subsea AS Senior Unsecured Bond Issue 2013/2020, DOF Subsea AS 9.50% Senior Unsecured Bond Issue 2017/2022 and FRN DOF Subsea AS Senior Unsecured Bond Issue 2018/2023) on 28 February 2022, whereby the bondholders on certain conditions approved to extend their waiver from, and suspension of, all payment obligations under each of the bond loans until 31 March 2022, with a possibility to further extend the standstill arrangement currently in place to 30 April 2022 with the approval of the ad-hoc committee of bondholders. Reference is further made to the announcements on 31 March 2022 regarding the ad -hoc committee's approval of extension of the standstill arrangement with the bondholders described above to 30 April 2022. Discussions and negotiations on the restructuring of the DOF group (the "Group") are progressing, and the Group, its secured lenders and the advisers to the bondholders have since the bondholders' meetings in February 2022 continued negotiations on an overall financial restructuring of the Group. Further progress has been made in such negotiations, but there are still certain issues that remain to be resolved to achieve an overall consensual restructuring of the Group. Consequently, no assurances can be made that the terms of a binding restructuring agreement will be agreed. DOF Subsea AS has requested Nordic Trustee AS to summon bondholders' meetings in the three bond loans to consider the extension of the standstill period initially until 31 May 2022 and with a possibility to extend the standstill period on one or more occasions to 30 September 2022 with the approval of an ad -hoc committee of bondholders to facilitate the finalisation of the negotiation and documentation of the proposed consensual restructuring. The proposal is further described in the attached summons to the bondholders in the three bond loans. A request will also be made to the Group's secured lenders to correspondingly extend the suspension of payments of principal and interest that have been granted by a majority of its secured lenders as necessary to finalise the restructuring. For further information, please contact: CEO, Mons S. Aase, tel: +47 91 66 10 12 CFO, Hilde Drønen, tel. +47 91 66 10 09 With a multi-national workforce of about 3,800 personnel, DOF ASA is an international group of companies which owns and operates a fleet of modern offshore/subsea vessels, and engineering capacity to service both the offshore and subsea market.
