Chairman's Statement

The Company has enjoyed another successful year. Further progress has been made in consolidating our position as a significant explorer and producer of oil and gas in Egypt and Morocco. Independent assessment has shown a considerable growth in our asset base in our Egyptian and Moroccan licences. Our producing assets in Egypt and Morocco provide a balanced portfolio of current revenue delivery and future opportunities for growth. Careful resource management and improvement of facilities, which are already being implemented, are helping us to maximise the resources that we have already discovered. There is also significant upside potential in our other assets, which will be instrumental in providing further upside for Circle's shareholders into the future.

Circle's acreage position and remarkable drilling success rate can be considered as an industry stand-out. I believe that the Company will continue to perform at this level throughout 2011 and into 2012, bolstered by the strong history of its drilling results and the experience of its management team.

The Company conducted an extensive drilling campaign in Morocco and Egypt throughout 2010. The drilling campaign was completed in Morocco in April 2011, whilst in the NW Gemsa Concession in Egypt, the ongoing appraisal and development drilling programme continues apace. To date, throughout 2010, and into early 2011 a total of nine wells have been completed and commercial hydrocarbons have been discovered and tested in eight of these wells, with one well in Morocco, which intersected gas, yet to be re-drilled as a result of encountering mechanical problems. In addition, one well in Egypt has been drilled as a water injector.

The entire Circle team warrants recognition for their skill and efforts in achieving this noteworthy drilling success rate. Although this could not have been achieved without the skill and expertise of Circle's technical team, it is the diligence and dedication of all our staff, associates and partners that has underpinned Circle's capacity to achieve such excellent results.

Operations

Morocco

Despite having to cope with heavy rainfall and intermittent flooding in Morocco, a five well campaign was finished in April 2011 with four tested commercial discoveries and well DRJ-6 from the 2009 drilling campaign also being successfully tested. Well KAB-1, although encountering gas shows, experienced mechanical problems and is planned to be re-drilled during the next drilling campaign.

On the production front, ONZ-4 and ONZ-6 continued in production in 2010. Wells KSR-8 and KSR-9 were also put into intermittent production for long-term testing and to supply local energy requirements with the combined rate of flow from both wells varying between 1.5 to 2.5 MMscfd. Negotiations are close to finalisation with additional gas users in the area and we expect to increase our customer base as soon as the new gas pipeline is completed in 2H 2011. This should see gas off-take increasing from today's levels up to 7 to 8 MMscfd in the latter part of 2011. The addition of a small diameter link from the existing infrastructure to a new client is also close to completion and this will see an immediate uplift in production of another 1MMscfd in the next few weeks.

An updated resource report was compiled by RPS Energy at the start of this month and the new estimate of most likely (P50) URR of gas is 30.6 bcf. This, together with our own internal estimate of gas production and resources remaining to be produced, in areas not included in the report, of 1.5 bcf, gives a total of 32.1 bcf URR for the Sebou Block. This represents an increase of gas resources of 83.5% over the 2010 figure of 17.5 bcf URR.

We are presently acquiring more 3D seismic over our Moroccan acreage and plan to start our next Rharb drilling campaign in early 2012.

Egypt

In Egypt, we have continued with successful appraisal and development wells on the NW Gemsa block. Three oil producers and one water injection well were drilled in 2010 and further development drilling is ongoing for 2011. New facilities, including gas production and water injection, are being progressed to maximise production and recovery efficiency and these should be completed by the end of 2011. The successful implementation of these measures should see significant increases in production levels in 2012. Daily production currently between 7,000 and 8,000 bopd is being managed in accordance with good oil field practice and through to the end of December 2010, total gross production was 4.1 MMBO.

The recent political unrest in Egypt had little impact on the Company's operational activities. Production continued as normal and suffered no delay while drilling was suspended for a couple of days due to a delay in getting necessary supplies from Cairo.

The situation in Egypt has, however, resulted in delays in receiving payment for our oil sales to EGPC (Egyptian General Petroleum Company). At year-end the amount past due was US$10.78 million and since year-end this has increased further. We are currently in discussions with EGPC with a view to resolving this matter and reducing these receivables to more normalised levels.

The updated resource report compiled by RPS Energy took into account the results of the drilling and development activity up to, but not including Geyad-3. The report estimates total most likely (P50) URR at 33.2 MMBO and 38.1 bcf of gas, which together equates to 39.8 MMBOE URR. This constitutes a 65.1% increase over the 2010 figure of 24.1 MMBOE URR.

We are delighted with the success on our NW Gemsa block as drilling progresses and new facilities are installed to maximise both reserves and the long-term uplifted production capability of the field.

Tunisia

In Tunisia, we have been conducting work in planning for exploration wells on the onshore Grombalia and Ras Marmour permits. This drilling activity is likely to be conducted in 2H 2011. In addition, legacy 2D seismic data has been obtained on the offshore Mahdia permit and incorporated into our prospect evaluation. Drilling plans are in progress with mobilisation costs likely to be shared with another area operator for 2012.

Oman

In Oman, we commenced a 900 sq km 3D seismic campaign over the southern portion of our Block 49 onshore. This has been processed and is currently undergoing interpretation as further work is completed to improve our evaluation of prospectivity and reduce the risk for potential drilling locations.

In Block 52 offshore, we started a 2D marine seismic survey in December 2010 which acquired some 5,000 additional kms of 2D. The survey was completed in early 2011 and submitted for processing. Work in 2011 will concentrate on interpretation of the survey together with legacy data, to refine the leads into drillable prospects and then completing a farm-out proposal on the acreage.

Corporate

In March 2011, in accordance with EU regulations relating to events in Libya, the Company froze the shareholding of Libya Oil Holdings (17.75% holding) until further notice. As of the date of this report the shareholding remains frozen.

Outlook

In 2011 and into 2012, Circle intends to further its exploration and production programmes with continued drilling in Egypt through additional appraisal wells and injector support drilling.

In Morocco, we will complete the recently started 3D survey, prepare to commence a further drilling campaign and also enjoy the value added to our country operations due to our new pipeline, which is being laid initially between our Sebou permit and Kenitra.

The coming year will see more operational activity in Tunisia with the drilling of two commitment wells in our land permits in Grombalia and Ras Marmour and we also look forward to more operational progress in Oman .

The Company continues to seek out new projects to increase its exploration and production base by acquiring development, redevelopment projects or producing assets or fiscally and regionally attractive exploration assets. This is a difficult task but we are determined to uphold our stringent technical and commercial requirements, which we believe have evidenced themselves throughout our present portfolio.

I reiterate my confidence and enthusiasm that we remain on track to repeat our success going forward and in doing so praise our teams in all countries for their professionalism and valued contributions to the continuing evolution of the Company.

I am delighted once again, to thank you our shareholders, for your support and to sincerely thank all our staff, associates and partners for their continuing good work and commitment during the past year.

Financial Review

Results for the year

Revenues for 2010 from oil and gas sales were significantly up at US$44.39 million, an increase of over 194% from 2009 revenues. This increase in sales revenue was due to both an increase in volume of oil sales (up by 221% compared to the previous year) and gas sales (up by 37% compared to the previous year) and an increase in both the oil and gas price achieved over 2009. The average oil price achieved for 2010 was US$75.74 per BO versus US$65.90 per BO in 2009 while the average gas price achieved was US$7.43 per Mscf as against US$7.19 per Mscf in 2009.

Gross profit for the year was US$16.90 million as against US$7.37 million for 2009, an increase of 129%.

Operating costs, including exploration expenditure written-off, amounted to US$4.32 million and was down by US$3.40 million on the previous year which resulted in an operating profit for 2010 of US$12.58 million (2009: operating loss of US$0.34 million).

After net finance costs for the year amounting to US$2.18 million (2009: US$13.13 million) the Group recorded a net profit before tax of US$10.40 million for 2010 (2009: net loss of US$13.48 million).

Fundraising

Circle announced on 3 August 2010 that it had successfully raised gross proceeds of US$66.40 million (£42.50 million) through a placing of 141,666,667 new ordinary shares with both existing and new institutional investors. The proceeds raised were targeted to accelerate the Groups exploration activities, fund capital expenditure in both Morocco and Egypt and fund new ventures. Evolution Securities acted as sole book-runner while Fox Davies Capital acted as co-lead manager.

Cash flow

Net cash inflow from operating activities for 2010 amounted to US$8.98 million (2009: US$1.38 million).

Net cash used in investing activities relating to oil and gas assets amounted to US$49.01 million (2009: US$37.57 million) and comprised mainly of US$19.31 million invested in exploration and evaluation assets in Morocco and Oman while US$29.70 million was invested in production and development assets in Morocco and Egypt.

Net cash generated from financing activities totalled US$64.84 million (2009: US$24.42 million) and comprised mainly US$66.40 million from the share placing noted above, US$3.67 million from the exercise of share options less share issue costs of US$3.43 million and interest paid of US$1.8 million.

Group cash balances at year-end amounted to US$47.11 million (2009: US$22.33 million) of which US$ 2.25 million was in restricted accounts leaving US$44.86 million available for use. Current cash balances amount to US$28.60 million of which US$27.35 million is available for use.

Consolidated statement of financial position

Total assets for the Group at 31 December 2010 amounted to US$203.87 million (2009: US$130.04 million) and comprised mainly oil and gas assets of US$137.12 million, cash at bank of US$47.11 million and US$19.35 million of trade and other receivables.

Net assets amounted to US$158.87 million at year end (2009: US$80.95 million) while working capital was US$59.11 million (2009: US$21.40 million).

The significant strengthening in the Groups statement of financial position was due mainly to the August 2010 capital raising and net profits generated for the year.

Glossary of terms

Notes to Editors

Circle Oil Plc (AIM: COP) is an international oil & gas exploration, development and production Company with an expanding portfolio of assets in Morocco, Tunisia, Oman and Egypt with a combination of low-risk near-term production and significant exploration upside potential. The Company listed on AIM in October 2004.

Internationally, the Company has continued to expand its portfolio over the past 2 years and now has assets in the Rharb Basin, Morocco; the Ras Marmour Permit in southern Tunisia; the Mahdia Permit offshore Tunisia; the Grombalia Permit in northern Tunisia and the Zeit Bay area of Egypt. Circle also has the largest licence holding of any company in Oman. In addition to its prospective Block 52 offshore, Circle also has an ongoing exploration program in Block 49 onshore.

Circle's strategy is to locate and secure additional licenses in prospective hydrocarbon provinces and through targeted investment programmes, monetise the value in those assets for the benefit of shareholders. This could be achieved through farm-outs to selected partners who would then invest in and continue the development of the asset into production, or Circle may itself opt to use its own expertise to appraise reserves and bring assets into production, generating sustained cash flow for further investment.

Further information on Circle is available on its website at www.circleoil.net.
