PRESS RELEASE

PARAGON OFFSHORE ANNOUNCES APPROVAL OF ADMINISTRATION APPLICATION AND APPOINTMENT OF JOINT ADMINISTRATORS IN THE UNITED KINGDOM

· English Court places Paragon Offshore plc in administration as part of ongoing chapter 11 process

· Joint Administrators from Deloitte LLP appointed

· Paragon will continue to operate in normal course during administration

· Paragon’s U.S. chapter 11 confirmation hearing scheduled to begin June 7, 2017 with chapter 11 emergence targeted for early July

HOUSTON, May 23, 2017 —Paragon Offshore plc (“Paragon” or the “company”) (OTC: PGNPQ) announced today that the High Court of Justice, Chancery Division, Companies Court of England and Wales (the “English Court”) considered the company’s previously disclosed application for administration in the United Kingdom and granted an order, pursuant to paragraph 13 of Schedule B1 to the Insolvency Act 1986, appointing two partners of Deloitte LLP as administrators of the company (the “Joint Administrators”) on Tuesday, 23 May 2017.

As previously disclosed, the appointment of the Joint Administrators is a necessary component of the consensual plan of reorganization (the “Consensual Plan”) under chapter 11 of the United States Bankruptcy Code that the company announced on May 2, 2017. Under the Consensual Plan, Paragon’s existing equity is deemed worthless and the company’s secured creditors and unsecured bondholders will receive equity in a new reorganized parent company. The next major milestone in Paragon’s chapter 11 cases is the confirmation hearing scheduled to begin on June 7, 2017 in the U.S. Bankruptcy Court in Delaware. Assuming the Consensual Plan is confirmed, Paragon is planning for its emergence from chapter 11 in early July; however, this timing is subject to the completion of certain conditions precedent to emergence including, among other things, the reorganization of the corporate structure of Paragon and its subsidaires.

As previously disclosed, under administration, Paragon will continue to conduct business in its normal course. Drilling contracts will continue and vendors and employees will continue to be paid. The Joint Administrators will assume all powers to manage the affairs of the company; however, Paragon’s existing board has agreed to remain involved in an advisory capacity to the Administrators until the company emerges from chapter 11, and the existing executive management team will remain responsible for the operational management of the Paragon group.

Additional Information

Details of the Consensual Plan can be found in the Current Report on Form 8-K filed by the company with the U.S. Securities and Exchange Commission (the “SEC”) on May 3, 2017. Additional information will be available on Paragon’s website at www.paragonoffshore.com or by calling Paragon’s Restructuring Hotline at 1-888-369-8935.
