Notice of Annual General Meeting

The Company announces that its Annual General Meeting ("AGM") will be held at, Trafalgar Court, Les Banques, St Peter Port, Guernsey, Channel Islands at 15.30 p.m. (BST) on Tuesday, 25 May 2021.

The Board of Directors of the Company notes the potential impact of the COVID-19 pandemic on the AGM and considers the well-being of Shareholders and other AGM attendees as a priority.

If the restrictions on travel introduced by the States of Guernsey to address the COVID-19 pandemic remain in place at the intended time scheduled for the meeting, physical attendance at the Annual General Meeting may not be possible. Accordingly, the Company urges Shareholders to vote by proxy and to appoint the chairman of the meeting as their proxy for that purpose. All votes on the resolutions contained in the Notice of Annual General Meeting will be held by poll so that all voting rights exercised by Shareholders, who are entitled to do so at the Annual General Meeting, will be counted.

Whilst restrictions in the Bailiwick of Guernsey have been eased, any person arriving into the Bailiwick of Guernsey is presently required to register their journey on a travel tracker and is required to self-isolate for a period of 14 days if they take a COVID test on Day 1 and another COVID test on Day 13 and have negative results. Otherwise if they decline to have a test they are required to self-isolate for 21 days upon arrival.

All Shareholders are urged to submit Forms of Proxy in respect of the AGM to ensure their vote is registered. Shareholders should complete and sign the Form of Proxy accompanying the Notice of AGM in accordance with the instructions printed on the Form of Proxy.

The Company will continue to monitor developments, including any regulatory changes as the situation in relation to COVID-19 continues. If it becomes necessary or appropriate to revise the arrangements for the AGM, further announcements will be made and information will be made available on our website at: http://www.RiverstoneREL.com/investors/reports-and-presentations/.

The Notice of AGM and Form of Proxy have been dispatched to all Shareholders. An electronic copy of the Notice of AGM and Form of Proxy are also available on the Company's website http://www.RiverstoneREL.com/investors/reports-and-presentations/.
