CIBC commenced an auction process to sell the producing interests in the Guaduas Oil Field. This included establishing data rooms in Houston and in Colombia and soliciting interests from fifty companies. Nine companies went through the data rooms. Bids from several prospective buyers were received in mid-November and this process resulted in the agreement with Sipetrol today. Remaining Assets and Operations After the sale, the only material assets of the Company and its subsidiaries will be the rights associated with the Deep Dindal association contract and certain Colombian tax assets. Neither the Company nor its subsidiaries will have sufficient cash to conduct any additional exploration activities. The Company has been actively seeking to secure additional financing or find a partner to participate in the completion of the Escuela 2 well and test the commercial potential of the Deep Dindal prospect. To date, the Company has been unsuccessful in these efforts; however, the Company is continuing its efforts to find a third party to provide the necessary financing to test the Escuela 2 well. Even if tested, there are no assurances that the Escuela 2 well would be productive and provide additional value. After December 15, 2002, the Company may be in default under the 12-1/2% $110 Million Senior Subordinated Notes. Now that the financial circumstances of the Company are more clearly defined, the Company will accelerate its discussions with representatives of the Senior Subordinated Noteholders. The Company has received notice from Chesapeake that it is currently in default under its 12% $45 Million Senior Secured Notes ("$45 Million Notes"). Chesapeake, as the collateral agent for the $45 Million Notes, holds a lien on the stock of all of the Company's subsidiaries and its cash accounts.
