Proposed Open Offer at 22p Per Share

Pan Andean Resources PLC 2 December 1999 PAN ANDEAN RESOURCES PLC PROPOSED OPEN OFFER OF 4,368,810 NEW ORDINARY SHARES AT 22 PENCE PER SHARE Introduction Following the announcement on 17 November 1999 that the Company had raised £3,747,098, before expenses, through a placing of 17,032,264 Ordinary Shares ('the Placing'), Pan Andean Resources PLC ('Pan Andean' or 'Company') is pleased to announce that it is proposing to raise up to £961,138 before expenses (£900,000 after expenses), through an open offer of 4,368,810 New Ordinary Shares at 22p per share ('the Open Offer'). The Company will be posting a Prospectus and Open Offer application form to Qualifying Shareholders on 6 December 1999. Background to and Reasons for the Open Offer Since acquiring the Chapare oil concession in central Bolivia in 1993, Pan Andean and partners have spent approximately $32 million on seismic, geophysical and geochemical studies of the hydrocarbon opportunities. The work to date has identified at least ten targets in the southern third of the block. We now intend to drill an exploratory well at Chipiriri some 22km north of Pan Andean's first well at Todos Santos. A suitable rig will shortly become available and Pan Andean expects to spud the well in early 2000. The total target depth is 3.75km metres and the expected drilling time is fifty days. Road, platform and well design is already underway. Since Chipiriri lies in virgin forest our civil construction partners must drive a road through to the well site. Pan Andean believes that the Chapare region is oil prone, with associated gas. Should we encounter commercial hydrocarbons, Pan Andean expects to extend an existing pipeline and refine liquids at the nearby refinery. There is export capacity in the existing products pipeline. A newly completed gas pipeline now provides access to the large and rapidly growing Brazilian market. Pan Andean has also studied gas markets within Bolivia and in neighbouring Argentina. As part of our fundraising exercise, including the recently completed private placing, Pan Andean wishes to offer existing shareholders the opportunity to subscribe for New Ordinary Shares at the same price as the investors in the private placing. Funds raised will be used to drill one or more wells in the Chapare block as well as cover corporate costs. Open Offer The Open Offer is being made by Rowan Dartington & Co. Limited ('Rowan Dartington') on behalf of the Company. Under the Open Offer, up to 4,368,810 New Ordinary Shares are being offered to Qualifying Shareholders at 22p per share, payable in full on application, on the following basis: 1 New Ordinary Share for every 11 Existing Ordinary Shares held at the close of business on 17 November 1999 and so in proportion for any other number of Existing Ordinary Shares then held. Qualifying Shareholders may apply for up to their maximum entitlement of New Ordinary Shares as set out in the Application Form enclosed with this document. Application forms are personal to Shareholders and may not be transferred except to satisfy bona fide market claims. Application forms, together with remittances for the full amount subscribed, must be received by the Company's registrars, Computershare Services (Ireland) Limited not later than 3.00 p.m. on 23 December 1999. Application forms may be split, but only to satisfy bona fide market claims, up to 3.00 p.m. on 21 December 1999. To the extent to which New Ordinary Shares are not applied for, Qualifying Shareholders should note that their entitlements will lapse and the Directors may instruct Rowan Dartington to place such New Ordinary Shares with other investors. Detailed information on the Open Offer, including the procedure for acceptance and payment, will be set out in the letter from Rowan Dartington contained in Part II of the Prospectus. Application has been made for all the New Ordinary Shares to be issued pursuant to the Open Offer to be admitted to listing on the Alternative Investment Market of the London Stock Exchange Limited. It is expected that admission to the Alternative Investment Market will become effective and that dealings will commence on 4 January 2000. Current Trading and Prospects The Directors believe that Pan Andean is now a well established company in oil and gas exploration in Bolivia. With the funds raised from the Open Offer and the recent Placing the Directors are confident that the Company's drilling programme in the current financial year can proceed as planned.
