                                    AGREEMENT

         THIS SALES AGREEMENT (this "Agreement") is made and entered into on May
1, 2003, by and between, EnerTeck Chemical Corporation, a Texas corporation (the
"Company") on the one hand, and Allan F. Dow & Associates, Inc., also a Texas
corporation (the "Sales Representative"-SR) on the other hand.

         In consideration of the mutual representations, warranties, covenants
and promises contained herein and other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties hereto agree
as follows:

         1. Services. For a period of two (2) year from the date hereof, SR will
use its professional and marketing contacts to assist the Company in promoting
its EnerBurn(TM) product at key accounts with the potential to purchase at least
40,000 gallons per year (the "SR's Accounts") are at least testing EnerBurn in
commercial applications.

         2. Compensation. The Company shall compensate SR with payment of
$100,000

when the SR's Accounts, which collectively have the potential to purchase 40,000
gallons of EnerBurn, have first introduced the EnerBurn product and it is
incorporated into a test and/or it is used on a commercial basis, in a
customer's fleet(s). SR and Company will mutually agree upon and determine, case
by case, on the potential to purchase EnerBurn, for each SR customer, that shall
apply to the aforementioned 40,000 gallon requirement that would trigger the
aforementioned $100,000 payment. In addition, SR will be paid up to $250,000 as
a commission from the sale of the first 40,000 gallons of EnerBurn sold by SRs;
this payment will be made at the rate of $6.25 per gallon of EnerBurn sold. In
both cases, payment to SR will be due 30 days from the date of shipment or the
date of invoice, which ever is earlier.

For EnerBurn sales effected by the SR in excess of 40,000 gallons, the Company
agrees to compensate SR consistent with the Company's Commission and Finder Fee
Policy for EnerBurn Sales developed for Company during the Term of this
contract. Commissions will be paid for thirty nine (39) months from the date of
the first sale to each new account independent of the Term of this SR Agreement.
Further, such Commissions, as a percent of revenue, shall be no less than 5% for
sales in months 1 thru 15, 3.5% for sales in months 16 thru 27, and 2% for sales
in months 28 thru 39. SR will keep Company advised of all sales opportunities
identified by SR.

In addition to the foregoing Fees, Company agrees to reimburse SR for reasonable
out-of-pocket expenses incurred by SR in performing Services in Paragraph 1.,
above. All expenses and any charges for Professional Services must be
pre-approved by Company.

         3. Independent Contractor. SR shall, at all times, render services
pursuant to this Agreement as an independent contractor and not as an employee,
agent or servant of Company, nor shall SR, by reason of this Agreement or the
services performed pursuant hereto, be deemed an employee of Company for
purposes of withholding employee payroll taxes, contributions, pensions or
otherwise.
