Lindal has extensive experience and competence corresponding well to these challenges, and it is considered to be in the best interests of the company and shareholders that he will be leading the Board of Directors through this phase.

Result from bondholders' meetings Reference is made to the summons to bondholders' meetings in DOFSUB07 (ISIN NO 001 0670144), DOFSUB08 (ISIN NO 001 078817.7) and DOFSUB09 (ISIN NO 001 083681.0) issued dated 3 April 2020 and the addendum to the summons issued 21 April 2021. The bondholders' meetings were held today, and the proposed resolution received 99.06%, 98.40% and 100% 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 and this pre-condition for a continued constructive dialogue between the DOF Group and its secured lenders and bondholders is then satisfied. Please see the attached minutes from bondholders' meetings. Update on tender activities There has been a sharp decline in the tender activities, with few new contract opportunities and less projects to bid for. Due to the sharp decline in the oil price, the oil companies have reduced their exploration activity substantially and some have also started to reduce existing production. It must be expected that the Group will continue to experience adverse consequences of the sharp decline in the oil price, and the responses of the oil companies to such decline. Several of the Group's vessels will finish their firm contract periods during 2020, and if the challenging market continues most of these vessels could move into lay-up. On the positive side, DOF is pleased to announce that Equinor Energy has awarded Skandi Vega a new contract. The vessel is owned by DOF Rederi. The duration of the contract is 6 months firm, with up to 6 months option. Equinor has an option to change the contract to a 2 or 3 year firm period within the next 4 months. Skandi Vega has been on contract to Equinor since the delivery in 2010. The new award is another sign of the quality provided by the crew and vessel. Due to the developments after the announcement of the financial report of the Group for the 4th quarter 2019, the expectations regarding EBITDA for 2020 expressed therein will no longer apply. It is currently too early to express any view on the expected EBITDA for 2020 in light of the changed environment.

ADDENDUM TO BONDHOLDERS' SUMMONS

April 21, 2020

DOF Subsea AS ("DOF Subsea" or the "Company", and together with its subsidiaries the "Group") has earlier requested and obtained approval for a new bond debt structure, as part of a comprehensive refinancing (proposals 5 December 2019, and revised proposal on 12 February 2020, together the "Original Refinancing Proposal"). These approvals were conditional upon, amongst others, approvals from secured lenders and the completion of a NOK 200 million equity raise within 30 April 2020. As described in the press release on 27 March 2020 (available on http://www.newsweb.oslobors.no/message/499850), the Company has, after the bondholder approvals were obtained, been faced with significant negative market developments not foreseen when the Original Refinancing Proposal was put forward, including the effect of COVID-19, the sharp decline in oil prices, and extreme currency fluctuations, which also have had a direct negative impact on the Company's liquidity. As a consequence of the sudden and significant uncertainties caused by these recent developments, the ongoing refinancing of the Group will necessarily be delayed and the Group has announced that it will continue its dialogue with the banks and bondholders to secure a long term financing solution, which also must be sufficiently robust after the recent developments. In order to facilitate such continued dialogue, the Company today summons bondholder meetings in the three bonds to approve a stand-still as further set out in the attached summons (the "Proposal"). During the first part of this period, the Company will seek to stabilize the situation (together with its major lenders), and then reopen the dialogue with all stakeholders, including secured lenders and bondholders. The Company has engaged ABG Sundal Collier ASA and Pareto Securities AS as its financial advisors with respect to the Proposal. Accordingly, Bondholders may contact ABG Sundal Collier ASA at +47 22 01 61 66 or Pareto Securities AS Fixed Income Sales at +47 22 87 87 70 for further information.

COMPANY UPDATE, REQUEST FOR STAND-STILL AND SUMMONS TO BONDHOLDERS' MEETINGS IN DOF SUBSEA AS

April 3, 2020

Financial calendar

April 2, 2020

DOF ASA ("DOF") and DOF Subsea AS ("DOF Subsea" and together with DOF and their respective subsidiaries the "Group") will below provide an update on the effects of the recent extreme currency fluctuations (including the liquidity impact), the sharp decline in the oil price and COVID-19 and an update on the ongoing refinancing process described in previous announcements by the Group. Currency effects and liquidity impact The negative development in the exchange rate for NOK has had a material negative impact on key financial figures of the Group, related to both equity/solidity and liquidity. Future currency developments will necessarily impact on these figures, but it is likely that the equity of the Group as of 31 March 2020 will be materially adversely affected by this development. The negative developments in the exchange rates for NOK have resulted in a currency loss in excess of NOK 200 million. Although the currency fluctuations have caused overdrafts on certain of the cash pool accounts comprised by DOF Subsea's Group Account Agreement, DOF Subsea has with the support from its lenders obtained a consent to the relevant limits being exceeded and is therefore not in default under these arrangements. Preliminary effects of COVID-19 and the decline in the oil price The Group has been able to continue normal operations of its vessels even if replacement of crew has become, and is expected to become, increasingly difficult due to COVID-19. However, there is a general increased risk in the sector of postponements of offshore projects as a result of COVID-19 and the decline in the oil price, which also could involve the Group`s vessels and assets even if the Group so far, naturally only to a limited extent, has been impacted by these events. It should therefore be expected that both COVID-19 and the oil price development will have an adverse negative effect on the Group. The sudden and extreme currency fluctuations have resulted in liquidity challenges for the Group. The Group is in a close and constructive dialogue with its banks in order to discuss alternatives to solve the liquidity situation of the Group in the short and medium term as a result of the recent developments. The Group has with the support of its lenders on very short notice already been granted a credit facility by certain of its lenders in the amount of NOK 100 million to cover its immediate liquidity needs. As part of these discussions, the parties are also discussing a new and larger credit facility to cover the Groups short term liquidity needs, required waivers from certain of the Group's covenants as of 31 March 2020, including both the equity and liquidity covenants, as well as deferrals of interest payments and amortizations. The Group has thereby in consultation with its secured lenders initiated a process to take the necessary steps to seek to secure the required liquidity for the Group. Due to the nature and extent of the recent developments, it is currently necessarily too early to conclude on all of the implications of such developments, including the Group's ability to successfully secure the required solutions with the banks and other creditors. Refinancing update The Group has previously announced that it expected to obtain an agreement with the banks for the refinancing (in the form of an agreed term sheet) by the end of Q1 2020. Such agreement was one of the conditions for the previously announced amendments to the bond loans approved by the bondholders of DOF Subsea. As a consequence of the sudden and significant uncertainties caused by the recent developments, the ongoing refinancing of the Group will necessarily be delayed. The Group has, however, established a constructive dialogue with its secured lenders with the objective to facilitate a continued financing of the Group and continue its dialogue with the banks and bondholders to secure a long term financing solution, which also must be sufficiently robust after the recent developments. It is, however, currently too early to assess the length of the delay and the implications of these events on the refinancing process.
