NON-NEGOTIABLE PROMISSORY NOTE

$125,000.00 April 1, 2006

FOR VALUE RECEIVED, the undersigned, Esconde Resources LP, a Texas limited partnership (“Maker”), hereby unconditionally promises to pay to The Jerry E. Polis Family Trust (“Payee,” together with Maker, the “Parties”), in lawful money of the United States of America, the principal sum of One Hundred Twenty Five Thousand Dollars ($125,000.00), together with interest on the unpaid principal balance from time to time outstanding, from the date hereof until the principal balance is paid in full, at a rate of 12.0% per annum (the “Interest Rate”). Interest will be calculated on the basis of a year of 365 or 366 days, as applicable, and charged for the actual number of days elapsed.

1. Payments

1.1 Principal and Interest. The principal amount of this Note will be due and payable in monthly installments, the first of which will be made on August 1, 2006 (each such date being a “Payment Date”). Principal will be paid out of Maker’s net cash flow from the Hamlett #1 well located in Scurry County, Texas. Each monthly payment of principal will be equal to no less than half of the monthly cash flow from said well. Maker will have the right, at any time, to prepay all or any portion of the outstanding principal amount without premium or penalty. All payments on this Note will be applied to the payment of accrued interest before being applied to the payment of principal.

1.2 Manner of Payment. Principal, interest, and all other amounts due under this Note will be payable, in U.S. dollars, to Payee by check or wire transfer in immediately available funds to an account designated by Payee in writing. If any payment of principal or interest on this Note is due on a day that is not a Business Day, such payment will be due on the next succeeding Business Day, and such extension of time will be taken into account in calculating the amount of interest payable under this Note. “Business Day” means any day other than a Saturday, Sunday or legal holiday in the State of Nevada.
