INVESTMENT IN CANADIAN OIL DEAL

Solo Oil plc, the AIM listed International Oil and Gas Exploration and Development Company, today announces it has paid Reef Resources Ltd ("Reef") the Stage 1 loan payment of C$750,000 as per the agreement announced on the 29th April 2010, pending the completion of the technical and legal due diligence which is expected to be by the 19th May.

The Reef team are currently executing on the Stage 1 work program to commence oil and gas production. Solo understands from Reef that the anticipated production re-start date is on or before June 1, 2010.

About Reef:

Reef is an incorporated oil and gas exploration and production company with existing assets in Ontario and ongoing negotiations and options for the acquisition of other assets in Canada. Reef's strategy is to build shareholder value through internally generated exploration and development drilling through selective acquisitions, joint ventures and farm-ins. Reef's primary asset in Ontario has estimated proved and probable reserves of 35,533 boe and 159,370 boe respectively as assessed by a qualified reserves evaluator in July 2009. The Ontario production asset is currently shut-in awaiting development financing.

The Ontario asset also has gas storage rights and a gas re-injection permit for gas re-cycle arbitrage and enhanced oil recovery. A key component of Reef's strategy is to identify and exploit undervalued prospects in the Ontario basin by utilizing the company's 23,500 acres of proprietary 3D seismic. In addition to its Ontario asset, Reef has identified multiple oil and gas acquisition and development opportunities throughout Canada.

Reef has established a four stage production development program on its Ontario asset which includes the drilling of a series of multi-zone well targets (vertical and horizontal) and executing recompletions and tie-ins. The loan from Solo covers the first two stages of expenditure on this program. The successful execution of this program will also enable Reef to capitalize on the gas storage and gas recycling rights on the acreage once depleted.
