                    ASSIGNMENT, LICENSE AND ROYALTY AGREEMENT

         THIS World-Wide Exclusive Assignment, License and Royalty Agreement
(the "Agreement") is made effective this 5th day of July, 2000 by, between and
among Hadronic Press, Inc., a Florida Corporation with principal offices at
35246 U. S. 19 North, Suite 115, Palm Harbor, Florida 34684-1909 ("UPI") and
EarthFirst Technology, Inc., with principal offices at 7887 Bryan Diary Road,
Suite 105, Largo, Florida 33777 ("EFT"). (EFT and HPI, collectively the
"Parties")

                                   BE IT KNOWN

         For a period commencing approximately 1978 through the date given
above, Dr. Ruggero Maria Santilli ("Dr. Santilli") has developed a technology
embodied in a number of scientific journals, reports and periodicals generally
under the heading of Hadronic Mechanics or similar identifiers. Over the course
of time, Dr. Santilli granted all rights to the results of his research to HPI
in exchange for, among other things, partial financial support for a period from
approximately 1984 through January 1998. The Santilli-HPI Agreement is annexed
hereto and made a part hereof as Exhibit 1.

         During November, 1997, EFT (formerly Toups Technology Licensing, Inc.)
was formed as a Florida corporation to, among other things, develop various
technologies in particular, a nonfossil, non-polluting alternative fuel. During
December, 1997, Dr. Santilli and EFT memorialized their association in that
Scientific Consultant Agreement under which Dr. Santilli would provide
scientific consultation relating to any EFT technology and EFT would provide the
financing and resources necessary to mature Dr. Santilli's theories to practical
application.

         At January, 1998, EFT engaged Dr. Santilli as the Company's Scientific
Advisor. At January, 1998, Dr. Santilli was predominately engaged in the
theoretical practice of his research. At that time Dr. Santilli sought to
acquire the funds and expertise to aid in developing equipment to substantiate
his Hadronic Mechanics theory as it relates to the production of a non-fossil,
non-polluting alternative fuel. During January, 1998 through June, 1998, EFT
expended approximately $500,000 and employed engineers, machinists and
significant managerial support such that on June 29, 1998, Dr. Santilli
submitted a US Patent application for ELECTROMAGNETION, file number 09/106,170.
During June, 1998, EFT received the worldwide exclusive rights to
ELECTROMAGNETION by virtue of the ELECTROMAGNETION License Agreement, Between
June and August, 1998, EFT expended approximately $500,000 and employed
engineers, machinists and significant managerial support such that on August 13,
1998, Dr. Santilli submitted a US Patent application for New CHEMICAL SPECIES
FOR GASES AND THEIR NEW TECHNOLOGIES, file number 09/133,348.

         From September, 1998 through September, 1999, EFT expended in excess of
$1,500,000 and employed engineers, machinists outside consultants and
significant managerial support such that on September 11, 1999, Dr. Santilli
submitted two US

Patent applications: MAGNEGAS, A NOVEL, HIGHLY EFFICIENT, NONPOLLUTANT, OXYGEN
RICH AND COST COMPETITIVE COMBUSTIBLE GAS AND ASSOCIATED METHOD file number
09/372,278 and DURABLE AND EFFICIENT EQUIPMENT FOR THE PRODUCTION OF A
COMBUSTIBLE AND NON-POLLUTANT GAS FROM UNDERWATER ARCS AND METHOD file number
09/372,277.

         On February 3, 2000, HPI re-assigned its world-wide rights to the above
cited patent applications to EFT such assignments are annexed hereto as Exhibit
2. During the course of 1999, Dr. Santilli and EFT developed initial commercial
uses based on the aforesaid patent applications for the production of a cutting
gas, irrigation water, and the destruction of certain liquid contaminants.

         HPI and EFT now desire to amend their agreements so that all rights to
the aforesaid patent applications as well as all derivatives, improvements or
associated patents or inventions thereof become housed in one corporate entity.
Further, the Parties hereon desire to construct an operating means to
efficiently commercialize current and future applications which are based in
whole or in part on the foregoing intellectual property as well as all
derivatives, improvements or associated patents or inventions thereof.

                                  NOW THEREFORE

         In consideration of the mutual promises and performances set forth
herein and ten ($10.00) dollars and other good and valuable consideration, the
Parties hereto unequivocally agree to the following terms and conditions.

         TERMINATION OF THIS AGREEMENT

         10.      TERMINATION. The Parties hereon acknowledge that major
portions of this Agreement will compel either or both Parties to take actions
which, in the future, would be difficult to terminate. The reassignment of
intellectual property from EFT to HPI, the issuance of common shares from EFT to
HPI and the payment of patent prosecution fees by HPI are items which,
regardless of the termination of this Agreement, would irrevocably alter the
position of both Parties. Those factors which could give rise to the termination
of the license rights granted USMAGNEGAS by HPI are set forth in the annexed
License and Royalty Agreement. This Agreement therefore may only be terminated:

                  a.       Becomes insolvent which insolvency is determined by
Certified Independent Public Accountants acceptable to both HPI and EFT;

                  b.       Declares bankruptcy;

                  c.       Fails to abide by any terms of this Agreement and
such default is not cured within 45 days following notice of such default.
Should either Party determine a default has occurred, notice shall be sent in
the manner described in item 19 hereon. Following the delivery of a default
notice, the receiving Party shall immediately set forth in writing (i) their
agreement/disagreement to such default and, if in agreement, specific steps to
cure such default within a 45 day period.

                  d.       Should the forty-five day period following proper
deliver of a default notice pass without corrective action, then this Agreement
shall be null and void and there shall be no further obligation of either party.

delay or omission by the parties to take action on account of such default, and
no express waiver shall affect any default other than the default specified in
the waiver and it shall be operative only for the time and to the extent therein
stated.

         13.      BENEFIT. This Agreement is made and entered into for the sole
protection and benefit of EFT and HPI, their successors and assigns and no other
person or persons have any right to action hereon or rights as a third party
