San Leon Energy plc

("San Leon" or the "Company")

Comment on News Article

San Leon Energy plc, the AIM listed company, focused on oil and gas development and appraisal in Africa and Europe, notes a media article in the Nigerian press relating to a claim by SunTrust Oil ("SunTrust") in respect of alleged payments due for the sale of their shares in Martwestern. The Company confirms it has received an application from SunTrust seeking leave (asking for permission) from the High Court Nigeria Holden to serve a petition outside the jurisdiction of Nigeria in respect of alleged amounts due.

Having taken legal advice, the Company believes the claim has no foundation (there being no outstanding liabilities to SunTrust from San Leon following the issue of San Leon shares to SunTrust in September 2016), and additionally the Nigerian courts lack jurisdiction for any such claim. The Company confirms it has instructed its Nigerian solicitors to file objections restraining the applications of SunTrust. This would have the effect of striking out the applications.
