In response to recent queries from shareholders regarding whether the financial restructuring that DOF ASA ("DOF" or the "Company", and together with its subsidiaries the "DOF Group") is seeking to agree with the creditors of the DOF Group will be required in light of recent market developments, the Company would like to reiterate that a financial restructuring of the DOF Group's capital structure will be required due to the significant debt level of the DOF Group. As previously communicated by the Company, a robust long-term financing solution is required for the DOF Group to maintain its status as a going concern. Such solution is still expected to require conversion of substantial amounts of debt to equity, which will significantly dilute the current holders of the equity. The current proposal being discussed with the secured creditors and bondholders of the DOF Group does not contemplate any unequal treatment of the shareholders of the Company. As previously informed, the dialogue with the lenders is complex, but constructive. A refinancing solution is not yet in place, and no assurance can at this stage be given that the Company will be able to find a solution with its creditors. If such solution is agreed, the shareholders are urged to consider the proposal when presented by the Company. For further information, please contact: CEO Mons 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. With 40 years in the offshore business, the group has a strong position in terms of experience, innovation, product range, technology and capacity. DOF's core businesses are vessel ownership, vessel management, project management, engineering, vessel operations, survey, remote intervention and diving operations primarily for the oil and gas sector. From PSV charter to Subsea engineering, DOF offers a full spectrum of top quality offshore services to facilitate an ever-growing and demanding industry. The company's main operation centers and business units are located in Norway, the UK, the USA, Singapore, Brazil, Argentina, Canada, Angola, and Australia.

Reference is made to previous announcements regarding the extension of standstill arrangements with the DOF group's secured lenders expiring 28 February 2022 and extension of standstill arrangements with bondholders in DOF Subsea AS' bond issues also expiring 28 February 2022. 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 March 2022. Reference is further made to the previous announcement on 11 February 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 March 2022 and with the possibility to extend to 30 April 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 100.00%, 96.33% and 100.00% of the votes in DOFSUB07, DOFSUB08, and DOFSUB09, respectively. Approval of the proposal set out in the summons required 2/3 majority in all three bonds, and the proposal was consequently approved. Please see the attached minutes from the bondholders' meetings. The extensions of the standstill periods will facilitate the DOF group's continued dialogue with its secured lenders and the bondholders under the DOF group's bonds regarding a long-term financial restructuring of the DOF group.

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 30 September 2021, 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 October 2021, with a possibility to further extend the standstill arrangement currently in place to 28 February 2022 with the approval of the ad-hoc committee of bondholders. Reference is further made to the announcements on 29 October 2021, 30 November 2021 and 31 January 2022 regarding the ad-hoc committee's approval of extension of the standstill arrangement with the bondholders described above to 28 February 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 September 2021 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. DOF Subsea AS has therefore requested Nordic Trustee AS to summon bondholders' meetings in the three bond loans to consider the extension of the standstill period initially until 31 March 2022 and with a possibility to extend the standstill period on one or more occasions to 30 April 2022 with the approval of an ad-hoc committee of bondholders. The proposal is further described in the attached summons to the bondholders in the three bond loans. A request has also been made to the Group's secured lenders to extend the suspension of payments of principal and interest that have been granted by a majority of its secured lenders.
