TECHNOLOGY LICENSING AGREEMENT

ADDENDUM #2

Whereas Verdisys and Mr. Landers have signed a Licensing Agreement April 25, 2003, and

Whereas both parties wish to execute a second amendment to the Licensing Agreement, and

     Whereas Verdisys’ performance of the following payment terms will constitute a full and complete settlement of all monies outstanding on the original License Fee to Mr. Landers, and

     Whereas all terms and conditions of the Licensing Agreement are still valid except as specifically agreed to in sections 1 through 5 below:

In consideration of the present needs and financial condition of Verdisys and the cash flow demands on Mr. Carl Landers, the parties agree to amend to the Licensing Agreement as follows:

1.	Verdisys will issue to Mr. Landers, at no cost to him, 300,000 new shares of common stock
	and $500,000.00 in cash. Such new shares shall become capable of being traded upon SEC
	declaration of effectiveness of the Verdisys SB-2 filing. All brokerage commissions and
	related expenses shall be borne by Verdisys provided that a discount broker is employed, or
	up to a maximum cost of 1% of sales value if a full service broker is used. Mr. Landers agrees
	that he will sell any and all shares according to the Verdisys, Inc. Insider Trading Policy and
	in such a way as to not adversely affect the trading value of the Verdisys stock.
2.	This agreement shall become effective upon receipt of the payment by Mr. Landers in the
	amount of $100,000.00, immediately following execution of this agreement, both of which
	shall occur no later than February 27, 2004. Verdisys also agrees to pursue a financing plan to
	raise $5 million and to pay the balance of $400,000.00 immediately following the first
	successful raise of new monies into the Company. In the event Verdisys finds it unnecessary
	or is unable to raise new monies, the $400,000.00 payment is due and payable no later than
	May 15, 2004. The failure of Verdisys to make the $400,000.00 payment no later than May
	15, 2004, shall result in the revocation of this Amendment #2, and the termination of the
	License Agreement. During the period of the financing effort, Verdisys agrees to provide
	regular written or e-mailed updates to Mr. Landers.
3.	Under this amendment, these payments totaling $500,000.00 will be considered as the initial
	License Fee payments and as such will be under the same provision set forth in 3-E of the
	License Agreement with no change.
4.	All other terms and conditions of the 2003 License Agreement, including the $500,00 per well
	payment provision and the grant back provisions for future developments, enhancements or
	improvements to the technology, will continue in full force and effect.
5.	In the event that Verdisys fails to perform under this agreement, the License is hereby
	terminated under the Licensing Agreement provision 3-E.
