Specific Disclosure

3.01 (c) (v)

1 It is intended that an employee share scheme will be set up by the Company just prior to the initial public offering of the Company’s shares on the AIM market of the London Stock Exchange plc. Options or shares will be issued to certain directors and key employees in accordance with the terms of the scheme. These options have already been verbally promised to certain key employees. The Company proposes to implement a share incentive scheme (which it is still designing with compensation experts) at the time of the proposed initial public offering and quotation on the AIM Market of the London Stock Exchange plc which will set aside approximately 10% of the share capital of the Company from time to time for grants to employees. The expectation is that at the time of the initial public offering the Company will make grants in respect of shares representing not more than 3% of the Company’s issued share capital immediately following the initial public offering.

2 Xxxxxxx Xxxx, an ex-employee of the Company, was promised options or shares as part of his remuneration package from the Company in exchange for lowering his daily consulting fee. There was never a formal service agreement between him and the Company. The number of options or shares he was eligible for was to be calculated dependent on the length of his service and performance. Following the termination of his employment, this grant of options or shares has never been fulfilled. The Company is currently in discussions with Xx Xxxx to agree a settlement of any claims he may allege. The Company does not expect any such settlement to exceed US$250,000.

3 Under a stock and asset purchase agreement dated May 2, 2002 (as amended by an amendment agreement dated October 18, 2002) between AES Gener S.A., Gener Argentina S.A., Oilgener Inc. (as Sellers), and Energy Holdings LLC (as Buyer) (the “SAPA”) Energy Holdings LLC granted AES Gener SA a capped royalty of 3.0% on the net remuneration from the Fell Block up to a maximum of US$ 3,250,000. The rights and obligations of Energy Holdings LLC were transferred to

GeoPark Argentina Limited by an acknowledgement agreement on 5 November 2002.

4 As partial consideration for the acquisition of the Del Mosquito exploitation concession, Cordex Petroleums Argentina Limited (now GeoPark Argentina Limited), as assignee, agreed to pay to EPP Petróleo S.A., as assignor, an overriding royalty interest of 2.5% (two point five percent) of the marketed hydrocarbons produced from the Del Mosquito area, if any.

5 As partial consideration for the acquisition of the Cerro Xxxx Xxxxx and Loma Cortaderal exploitation concessions, Cordex Petroleums Argentina Limited (now GeoPark Argentina Limited), as assignee, agreed to pay to Triton Argentina Inc. (now Vintage Petroleum), as assignor, an overriding royalty interest of 8.0% (eight percent) of the aggregate future hydrocarbon production, if any, from the areas covered by the Cerro Xxxx Xxxxx and Loma Cortaderal concessions. Vintage shall be entitled to take the hydrocarbon production in kind or have such production marketed by GeoPark Argentina Limited on arms length competitive commercial basis from time to time. If Vintage chooses to have GeoPark Argentina Limited market such production, GeoPark Argentina Limited shall pay the proceeds to Vintage within 10 days of receipt of the funds by GeoPark Argentina Limited from the sale of hydrocarbons from the Cerro Xxxx Xxxxx and Loma Cortaderal areas.

3.01(g)(ii)	1 Secretary of Energy Resolution 5/1996 requires the holder of an Exploitation Concession to file yearly, on or before January 31 each year: · A proposed schedule of well abandonment works to be undertaken during relevant year; and · A report on well abandonment works completed during previous year. The well abandonment schedules filed by the branch of GeoPark Argentina Limited with the Argentine Secretary of Energy on February 24, 2005 display the following situation:

	CONCESSION	# of Plugged Xxxxx	# of Inactive Xxxxx to be plugged	Deadline to plug inactive xxxxx
	Del Mosquito	26	16	January 9, 2011
	Cerro Xxxx Xxxxx	4	1	January 9, 2011
	Loma Cortaderal	2	1	January 9, 2011

2 Until December 31, 2003, the branch of GeoPark Argentina Limited held a gas flaring licence to flare up to 25,000m3/day of natural gas at Del Mosquito block. Such licence was granted by Disposition 80/2003 of the Sub-secretary of Fuels, as there were no natural gas connection and transmission facilities to allow the marketing of the natural gas production. After the expiration of such licence, upon notice to the Secretary of Energy and based on technical evidence that the natural gas production was being exhausted, the branch of GeoPark Argentina Limited continued to flare gas volumes within the limits of what the Company is able to flare under Argentine law.

3 Mendoza Water Departments Inspections: During 2002, the Water Department of the Province of Xxxxxxx inspected the Loma Cortaderal and Cerro Xxxx Xxxxx blocks and made the following observations:

LCx-1 well: the discharge system was not considered safe enough to prevent spills into the Buta Mayin creek. The branch of GeoPark Argentina Limited replied that it was not necessary to build an additional system to prevent a possible leak into the Buta Mayin creek, since the natural flow of the well is extremely low. That notwithstanding, the branch of GeoPark Argentina Limited committed to level the loading facility area and to construct a natural ditch with natural walls to contain possible oil leaks in that area. The branch of GeoPark Argentina Limited did not receive any further requirements from the authorities in connection with this event.

ABM x-1 well: two containers with hydrocarbon were allegedly found flowing into the Buta Ranquil creek. The branch of GeoPark Argentina Limited replied that during the last environmental audits, the fluids in the containers were tested and proved extremely low hydrocarbon content. Accordingly, there was no possibility the creek would be polluted. That notwithstanding, the branch of GeoPark Argentina Limited will study other additional improvements such as the improvement of the walls of both containers to ease the natural drainage of clean water therein contained to the Buta Mayin creek. The branch of GeoPark Argentina Limited did not receive any further requirements from the authorities in

connection with this event.

CDJ-x1 well: Oil and water leaks were allegedly observed between flanges. The branch of GeoPark Argentina Limited replied that it would evaluate the intervention of the well to either put it in production or abandon it definitively. The well was repaired twice and its final repair is not considered appropriate until a final decision is taken on the abandonment or activation of the well. The branch of GeoPark Argentina Limited did not receive any further requirements from the authorities in connection with this wellhead.

CDJ-x2 well: The wellhead cellar was allegedly found loaded with water and oil due to wellhead leakage. The branch of GeoPark Argentina Limited replied that it would undertake studies to decide the intervention or final abandonment of the well. That notwithstanding, a cellar was built to contain the leaks and works were carried to minimize them. The well is inspected regularly to prevent any spills. On January 4th, 2006, the branch of GeoPark Argentina Limited was notified of Resolution 388 passed by the Sub-secretary of the Environment whereby the branch of GeoPark Argentina Limited was required to submit within 10 days a work plan to remediate the soil contaminated with oil in old spills near the location of the CDJ-x2 well. The branch of GeoPark Argentina Limited committed to carry out a remediation plan which has now been implemented.

4 Secretary of Energy Resolutions 340/93 and 25/04 require the holders of Exploitation Concessions in the Austral Basin to file on or before February 28 each year an Annual Survey of Works and Tasks Study prepared by an environmental consulting firm registered with the Secretary of Energy.

Del Mosquito: The 2005 Annual Survey of Works and Tasks Study for the Del Mosquito block reports that all material mitigation and remediation measures recommended in the immediately preceding year are either in process or have already been implemented by the branch of GeoPark Argentina Limited. Newly recommended high priority mitigation and remediation measures include: to build a spill tray in battery “A”, to build waterproof collecting trays to prevent harm to the soil, to fix up emergency pools in batteries “A” and “B”, to protect pumping equipment in productive xxxxx, to remedy the pool in the “DM-5” well and to remedy and patch the pool in the “DM-18” well.

Cerro Xxxx Xxxxx & Loma Cortaderal: An inspection of all xxxxx is carried out every two months at the Loma Cortaderal block. Some of the 2004 recommended mitigation and remediation measures were not implemented and the 2005 Annual Survey of Works and Tasks Study has recommended the following high priority measures: to signal both the area and the xxxxx in it, to waterproof the LC x-1 well, to keep the roads in good general condition, and to prevent water

accumulation in the pools of the ABM X-1 well.

5 GeoPark Chile Limited is obligated to obtain an environmental permit to operate a pipeline. On October 17, 2005, an advisor was hired to prepare and file an Environmental Impact Declaration (Declaración de Impacto Ambiental) before the regional environmental agency COREMA. This Environmental Impact Declaration is expected to be submitted by GeoPark Chile Limited by February of 2006.

If environmental impact is small, an Environmental Impact Declaration will be sufficient and after 60 business days a permit will be granted. If the impact is deemed to be other than small, an Environmental Impact Study will have to be prepared which is used for wider consultation-. According to the information that GeoPark Chile Limited possesses at present and based on the conclusion of the environmental consultant, an Environmental Impact Declaration would be sufficient for this preliminary stage of the project.
