Fully Underwritten Rights Issue

18 May 2017. The board of directors of Siem Offshore Inc (the “Company”) has resolved to carry out a fully underwritten rights’ issue with gross proceeds of NOK 190 million (the "Rights Issue").

The net proceeds from the Rights Issue will be used for working capital purposes and some minor capital investments and to serve interest and instalments on the Company´s debt in accordance with its repayment schedules and thereby continue to reduce the Company's debt leverage.

The subscription price in the Rights Issue is set to NOK 1.90 per new share and 100,000,000 new shares will be issued.

In connection with the Rights Issue, the Company has entered into an underwriting agreement with Siem Europe S.à r.l. (the “Underwriter”), a wholly owned subsidiary of Siem Industries Inc, who upon and subject to certain conditions underwrite the subscription of all the shares to be offered in the Rights Issue. New shares not subscribed for by the end of the subscription period will thus be allocated to the Underwriter. The Underwriter will receive an underwriting fee corresponding to 1.00% of the underwritten amount.

A prospectus relating to the Rights Issue, to be approved by the Financial Supervisory Authority of Norway, will be prepared by the Company. The prospectus will be made public prior to the subscription period and represent the subscription material for the Rights Issue. Provided that the prospectus for the Rights Issue is approved by the Financial Supervisory Authority of Norway in time, the subscription period will commence on 30 May 2017 and end on 12 June at 16:30 hours (CET). If the prospectus is not approved in time to maintain this subscription period, the subscription period will commence on the first trading day on the Oslo Stock Exchange following approval of the prospectus and end two weeks thereafter.

Existing shareholders will be granted subscription rights for the shares offered in the Rights Issue pro rata to their existing shareholding in the Company. The shareholders will receive subscription rights on the basis of their shareholding in the Company as of the expiry of 19 May 2017 (as registered in the Company's shareholder register in the VPS as of the expiry of 23 May 2017 (the “Record Date”)). Oversubscription and subscription without subscription rights will be permitted. The subscription rights will be freely tradable and listed on the Oslo Stock Exchange.

The Company has appointed Swedbank Corporate Finance as Manager for the Rights Issue. Advokatfirmaet Wiersholm AS is the Company's legal counsel.
