("Union Jack" or the "Company")

AGM Resolutions

Union Jack Oil plc (AIM: UJO), announces it has received a request for certain ordinary resolutions to be included in the business to be considered by shareholders at the Company's forthcoming annual general meeting ("AGM") (the "Resolutions").

The request has been made on behalf of a shareholder holding a total of 13,421,874 ordinary shares in UJO, equivalent to approximately 9.16% of the Company's issued share capital (excluding shares held in treasury).

In addition to ordinary resolutions to put each of the current Board directors up for re-election (in accordance with best practice, as followed by the Company at last year's AGM), a resolution has been proposed to appoint former director, Craig Howie, to the Board of the Company.

In accordance with its obligations under company law, the Board will include the Resolutions in the notice of the Company's forthcoming annual general meeting to be held in June.
