WITNESSETH: Purchaser has performed plugging, abandonment and/or closing of the Tajiguas Facility and the Molino Field facilities in or offshore California and may hereafter conduct certain related limited environmental monitoring activity that has been proposed by Purchaser in plans currently under review by California governmental bodies or agencies (hereinafter the entirety of the foregoing is referred to as "the Work"); Purchaser has incurred costs and expenses for the portion of the Work that has been performed and has authorized prior hereto expenditure for the portion of the Work that has been proposed by Purchaser in plans currently under review by such governmental bodies or agencies (hereinafter all such costs, expenses and authorized expenditure are referred to as "the Cost"); Seller is obligated to bear a portion of the Cost, its share being one million one hundred thousand five hundred nineteen point seventy-one Dollars ($1,100,519.71); and In satisfaction of such obligation and payment for Seller's share of the Cost, Seller wishes to sell, and Purchaser wishes to buy, shares of Seller's common stock and warrants to purchase additional shares of such common stock on the terms and conditions set forth in this Agreement. The parties, intending to be legally bound, hereby agree as follows: 1. Sale and Purchase of Units -------------------------- 1.01 Agreement to Sell and Purchase.

The sale and delivery of the Units at Closing shall be in satisfaction and payment of, but only of, Seller's share of the Cost.
