Corporate Presentation

Disclaimer

The information contained in this document (the "Corporate Presentation") has been prepared by Jersey Oil and Gas Plc ("JOG"). JOG is a UK company quoted on AIM, a market operated by London Stock Exchange plc. This Corporate Presentation has not been fully verified and is subject to material updating, revision and further verification and amendment without notice. This Corporate Presentation has not been approved by an authorised person in accordance with Section 21 of the Financial Services and Markets Act 2000 (as amended) ("FSMA") and therefore it is being provided for information purposesonly.

While the information contained herein has been prepared in good faith, neither JOG nor any of its directors, officers, agents, employees or advisers give, have given or have authority to give, any representations or warranties (express or implied) as to, or in relation to, the accuracy, reliability or completeness of the information in this Corporate Presentation, or any revision thereof, or of any other written or oral information made or to be made available to any interested party or its advisers (all such information being referred to as "Information") and liability therefore is expressly disclaimed. Accordingly, neither JOG nor any of its directors, officers, agents, employees or advisers take any responsibility for, or will accept any liability whether direct or indirect, express or implied, contractual, tortious, statutory or otherwise, in respect of, the accuracy or completeness of the Information or for any of the opinions contained herein or for any errors, omissions or misstatements or for any loss, howsoever arising, from the use of this Corporate Presentation.

The views of JOG's management/directors and/or its partners/operators set out in this document could ultimately prove to be incorrect. No warranty, express or implied, is given by the presentation of these figures here and investors should place no reliance on JOG's or any operator's estimates cited in this document.

No assurance can be given that hydrocarbon resources and reserves reported by JOG, will be recovered at the rates estimated or that they can be brought into profitable production. Hydrocarbon resourceand reserve estimates may require revisions and/or changes (either up or down) based on actual production experience and in light of the prevailing market price of oil and gas. A decline in the market price for oil and gas could render reserves uneconomic to recover and may ultimately result in a reclassification of reserves as resources. There are uncertainties inherent in estimating the quantity of resources and reserves and in projecting future rates of production, including factors beyond JOG's control. Estimating the amount of hydrocarbon resources and reserves is an interpretive process and, in addition, results of drilling, testing and production subsequent to the date of an estimate may result in material revisions to original estimates. Any hydrocarbon resources data contained in this document are unaudited management estimates only and should not be construed as representing exact quantities. The nature of reserve quantification studies means that there can be no guarantee that estimates of quantities and quality of the resources disclosed will be available for extraction. Therefore, actual production, revenues, cash flows, royalties and development and operating expenditures may vary from theseestimates. Such variances may be material. Any reserves estimates contained in this document are based on production data, prices, costs, ownership, geophysical, geological and engineering data, and other information assembled by JOG (which it may not necessarily have produced). The estimates may prove to be incorrect and potential investors should not place reliance on the forward looking statements contained in this document concerning JOG's resources and reserves or potential production levels. Hydrocarbon resources and reserves estimates are expressions of judgement based on knowledge, experience and industry practice. They are therefore imprecise and depend to some extent on interpretations, which may ultimately prove to be inaccurate. Accordingly, two different independent parties may not necessarily arrive at the same conclusions. The views of management/directors as set out in this document could ultimately prove to be incorrect. Estimates that were reasonable when made may change significantly when new information from additional analysis and drilling becomes available.

This Corporate Presentation may contain "forward-looking statements" that involve substantial risks and uncertainties, and actual results and developments may differ materially from those expressed or implied by these statements. These forward-looking statements are statements regarding JOG's intentions, beliefs or current expectations concerning, among other things, JOG's results of operations, performance, financial condition, prospects, growth, strategies and the industry in which JOG operates. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. These forward-looking statements speak only as of the date of this Corporate Presentation and JOG does not undertake any obligationto publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date of this Corporate Presentation.
