AUSTIN, Texas--(BUSINESS WIRE)--April 28, 2003

DeMarco Energy Systems of America Inc. (OTCBB:DMES) is pleased to announce the sale of its ninth Filter Service Distributorship.

The down payment for the Southeast Austin, Texas distributorship has been received. This completes the Central Texas corridor from north of Waco to north of San Antonio, where sales are already being generated. The company expects to complete this distributorship and receive the final funding the end of July. DeMarco is building other filter service distributorships throughout the Central Texas and West Texas areas.

"This area of our business is growing rapidly and we expect to announce the completion of the distributorships that are 'under construction' in the near future. This division has brought stability to the DeMarco financial condition and is a significant aspect of the day-to-day positive cash flow. We are currently building new territories and expect to begin selling distributorships in other areas of Texas in the very near future. We believe that these distributorships are the most unique and the best opportunity in the nation," stated William C. Berry, Chairman of DeMarco Energy.

A DeMarco Energy distributorship costs $150,000.00 and will return a cash flow of at least $45,000.00 per year to the owner after all expenses and payments. This cash flow starts the very first year. The unique DeMarco Filter Service Distributorship concept allows the distributor the freedom to expand and grow the business while enjoying a great cash flow. It is expected that all distributorships will grow at a minimum of 20% per annum.

The DeMarco distributorship is a total turnkey operation in which the distributor will start with all the sales, tools, inventory and equipment necessary to operate the business. The typical loan requires an initial down payment and repayment of the loan within a period of five years. DeMarco will provide management assistance, which includes accounts receivable accounting, bookkeeping, sales and payroll reports, new sales assistance, installation assistance and most other management areas that may be required.
