residence is 6707 Corte Calabeza, Tucson, Arizona (the "Employee"). The Company
and Employee are referred to collectively herein as the "Parties."

In consideration of the mutual covenants and promises contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the Parties hereby agree as follows:

Employment. The Company hereby employs Employee as the Polymers Plus G.M. and
employee of the Company. Employee hereby accepts such employment and agrees to
perform those duties and undertake those responsibilities as are customarily
performed by others holding similar positions in similar businesses. Employee
shall perform the duties that are described in the Job Description attached
hereto as Exhibit 1, and Employee shall perform all other duties and activities
that are assigned to Employee by Employee's supervisors or by the Board of
Directors of the Company, as long as such assigned duties and activities are not
inconsistent with the other duties and activities of Employee that are described
in this paragraph. Employee shall report directly to and be supervised by the
President of his designee.

Full-Time Best Efforts. Employee shall devote substantially all of Employee's
full professional time and attention to the performance of Employee's
obligations under this Agreement, and will at all times faithfully, industrially
and to the best of Employee's ability, experience and talent, perform all of
Employee's obligations hereunder. Employee may have other business investments
and participate in other business ventures that, from time to time, require
minor portions of Employee's time, provided that such activities do not
interfere or conflict and are not inconsistent with employee's duties hereunder
and are not detrimental to the Company's business interests.

Term of Employment. The term of Employee's employment shall commence on the
Effective Date and, unless terminated earlier pursuant to the provisions of this
Agreement, shall continue for three years (the "Initial Term"). Upon the
expiration of the Initial Term, Employee's employment by the Company under the
terms of this Agreement shall automatically be renewed for successive 3-year
increments unless written notice is given by either party within 90 days of the
anniversary date on which this Agreement would otherwise terminate. The term of
this Agreement as provided in this Section 3 is referred to herein as the
"Term."

Compensation.

Salary. Until termination of Employee's employment hereunder, unless otherwise
provided herein, the Company shall pay Employee an annual base salary of not
less than $75,000, less applicable withholdings, payable in equal monthly (or
other more frequent periodic) installments at the usual times as payment of
compensation to the Company's senior employees. Employee's base salary shall be
reviewed no less frequently than once each year and may be increased as the
Board of Directors may, in their sole discretion, approve.

Benefits. If the Company elects in its sole discretion to establish any such
plans, Employee shall be entitled to participate in the Company's benefit plans,
including but not limited to any group medical and/or dental plan; group life,
disability or other insurance; and/or 401(k) profit sharing plan, as such plans
are generally available from time to time to similarly situated employees of the
Company. Employee will be entitled to two weeks of paid vacation per year,
earned in accordance with the Company's vacation policy and the Company will
provide a suitable business vehicle.
<PAGE>

promoting  the business of the Company,  including  expenses for  entertainment,
travel and similar  items.  Employee shall obtain and shall provide on a monthly
basis to the Company  receipts  sufficient in detail to satisfy the  information
requirements  of ss.274 of the Internal  Revenue Code of 1986,  as amended.  The
Company shall directly pay or shall reimburse Employee for all such reasonable
expenses upon the request of Employee.

Vacation Days. Employee shall be entitled during the term of this Agreement to
an annual vacation at the rate provided to other executive officers of the
Company (but in no event fewer than 10 working days per calendar year), during
which time Employee compensation shall be paid in full. Employee shall be
entitled to take vacation days at such time or times and in such combination as
Employee shall choose, subject only to the needs and exigencies of the business
of the Company, but Employee shall not take vacation days at such times or in
such combinations as will substantially impair Employee's ability to carry out
Employee's duties under this Agreement or as will substantially impair or harm
the Company's business.

             EXECUTIVE EMPLOYEE CONFIDENTIALITY, NON-COMPETITION AND
                         INVENTION ASSIGNMENT AGREEMENT

This EXECUTIVE EMPLOYEE CONFIDENTIALITY, NON-COMPETITION AND INVENTION
ASSIGNMENT AGREEMENT (the "Agreement"), effective as of January 4, 2000 (the
"Effective Date"), is entered into by and between AMERICAN SOIL TECHNOLOGIES,
INC., a Nevada corporation (the "Company"), and RONALD SALESTROM, whose
principal residence is 6707 Corte Calabeza, Tucson, Arizona (the "Employee").
The Company and Employee are referred to collectively herein as the "Parties."

                                    Recitals

A. As of the Effective Date, the Company and Employee have entered into a
separate Executive Employee Employment Agreement Between AMERICAN SOIL
TECHNOLOGIES, INC. and RONALD SALESTROM (the "Employment Agreement"). Unless
otherwise defined herein, capitalized terms used in this Agreement have the
meanings given in the Employment Agreement. In the event of any conflict between
the terms of this Agreement and the Employment Agreement, the terms of the
Employment Agreement shall govern.

B. Employee's employment by Company creates a relationship of confidence and
trust between Employee and Company with respect to certain information
applicable to the business of the Company and its clients or customers.

C. The Company possesses and will continue to possess information that has
commercial value and is treated by Company as confidential. Such information may
include information created, discovered or developed by Employee during the
period of or arising out of Employee's or Employee employment by Company,
whether before or after the date hereof. Such information may also include
information belonging to Company's owners, managers, clients, business partners,
customers or suppliers. All such information is hereinafter called "Confidential
Information." Confidential Information for purposes of this Agreement also
includes, without limitation, discoveries, developments, designs, improvements,
inventions, blueprints, structures, software, processes, computer programs,
know-how, data, techniques, formulas, marketing, and business plans and
outlines, strategies, budgets, forecasts, projections, unpublished financial
statements, costs, fee schedules, client and supplier lists, client and
prospective client databases, access codes and similar security information and
procedures, and all patents, copyrights, maskworks, trade secrets and other
proprietary rights thereto; provided, however, that the term "Confidential
Information" shall not include any of the foregoing that is in the public domain
other than as the result of a breach of an obligation of confidentiality.

D. Employee recognizes that any unauthorized use or disclosure of Confidential
Information would cause serious injury to Company, and that the Company's
willingness to employ Employee depends upon Employee's commitment to protect
Company's Confidential Information and to comply with all of the provisions of
this Agreement

Agreement

Therefore, for good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Company and Employee hereby agrees as
follows.

Protection of the Confidential Information. At all times during and after
Employee's employment, Employee shall hold all Confidential Information in
confidence and shall protect it with utmost care. Employee shall not disclose,
retain, copy, or permit any unauthorized person to disclose or copy any of the
Confidential Information, except as may be necessary for the conduct of the
Company's business. Employee shall not use any of the Confidential Information
except as necessary to perform Employee's duties as an employee of the Company
as provided in this Agreement and in the Employment Agreement.

Confidential Information Belonging to Third Parties. In the event that Employee
has or has had access to any Confidential Information belonging to any third
party, including but not limited to any of Employee's previous employers,
<PAGE>
Employee shall hold all such Confidential Information in confidence and shall
comply with the terms of all agreements between Employee or Company and any
third party with respect to such Confidential Information.

Exceptions. This Agreement is not to prevent the use or disclosure by Employee
of information that (a) is required by law to be disclosed, but only to the
extent that such disclosure is legally required, (b) becomes a part of the
public knowledge other than by a breach of an obligation of confidentiality, or
(c) is rightfully received from a third party and neither the Company nor
Employee is obligated to hold such information confidential.

Return of Confidential Information. Upon the Company's request, and in any event
upon termination of Employee's employment by the Company for any reason,
Employee shall promptly return to Company all materials in Employee's or
possession or control that contain or represent Confidential Information,
including but not limited to documents, drawings, diagrams, flow charts,
computer programs or files, memoranda, notes, and every other medium, and all
copies thereof.

Non-Competition.

Acknowledgement. Employee acknowledges that (i) the Company and/or its
affiliated and subsidiary organizations are engaged in a variety of business
endeavors; including development of applications for mixing liquids and gases in
small particle sizes (the "Business"); (ii) the Business is conducted throughout
the United States and is expected to be conducted in one or more countries
internationally; (iii) Employee's work for the Company will give Employee access
to trade secrets and confidential information concerning the Company and the
Business, including, without limitation, proprietary information and trade
secrets, investor addresses and contact lists, techniques for raising
development capital for the Company; (iv) the ability of the Company and its
affiliates to continue the Business is likely to be materially jeopardized and
the value of the Company and its affiliates reduced if Employee competes with,
or assists other persons in competing, with the Company and/or any of its
affiliates.

Covenant Not to Compete. Therefore, for a period of 3 years from the date of any
termination of Employee's employment by the Company for any reason, Employee
shall not anywhere in the world, accept employment with or render any service to
a direct competitor of the Company or create or engage in creating or conducting
a competing business. Said Covenant shall not apply in the event that the
Licenses Agreement entered into between Employee and Employer has been
terminated.

"Direct Competitor" and "competing business" for purposes of this Agreement mean
any business or entity that is in any business that is the same or similar to
the Business.

Employee acknowledges that the restrictions imposed by this Agreement are
reasonable and will not preclude Employee from being gainfully employed in other
ways and activities following a termination of employment with the Company.

Without limiting the foregoing, Employee also agrees that, during the Term of
the Employment Agreement, and for a period of 3 years after termination of the
Employment Agreement, Employee shall not do any of the following: carry on any
business or activity (whether directly or indirectly, as a partner, shareholder,
owner, principal, agent, director, affiliate, employee, advisor, or consultant,
or in any other capacity) which is competitive with the Business as conducted by
the Company at the time of termination of Employee's employment.

Enforceability. If any court shall determine that the duration, geographic
limitations, subject or scope of any restriction contained in this Section 5 of
this Agreement is unenforceable, it is the intention of the parties that this
Section 5 of this Agreement shall not thereby be terminated but shall be deemed
amended to the extent required to make it valid and enforceable, such amendment
to apply only with respect to the operation of this Section 5 of this Agreement
in the jurisdiction of the court that has made the adjudication.

                                       2
<PAGE>
Assignment of Inventions. Employee agrees to disclose and to assign immediately
to the Company, or to any persons designated by the Company, or at the Company's
option, any of the Company's successors or assigns, all inventions or
improvements which are or were made, conceived or reduced to practice by
Employee, whether acting independently or with others, during the course of
Employee's employment with the Company, and which (i) were made, conceived of or
first reduced to practice in the performance of any duties assigned to or
undertaken by the Employee as an employee of the Company; or (ii) were made,
conceived of or first reduced to practice with the use of the Company's time,
material, facilities or funds. Such inventions are referred to herein as
"Inventions."

This Agreement shall not diminish the effect or binding nature of nay prior
invention assignments made to the Company by Employee.

Without limiting the foregoing, at all times the Company (or its nominee) shall
have the right to obtain, for its own benefit and in its own name (and entirely
at its expense) patents and patent applications of any type, and all renewals
and extensions of such patents and applications for the inventions and
improvements described in this Section.

In order to protect the right, title and interest of the Company (or its
successors, assigns or nominees) in such inventions or improvements, in
connection with any applications or patents necessary to convey rights to those
improvements or inventions to the Company, Employee shall, without further
compensation, execute and deliver all papers and instruments and perform such
further acts, including giving testimony or furnishing evidence in the
prosecution or defense of appeals, interferences, suits and controversies
relating to any of the inventions or improvements, as may be deemed necessary by
the Company.

Additional Cooperation with Respect to Inventions. Employee shall (a) treat all
information with respect to Inventions as Confidential Information within the
meaning of this Agreement; (b) keep complete and accurate records of the
Inventions, which records will be the property of Company; (c) testify in any
proceedings or litigation related to the Inventions; and (d) in case the Company
will desire to keep secret any Inventions or will for any reason decide not to
have letters patent applied for thereon, refrain from disclosing the Invention
and from applying from letters patent thereon.

Assistance of the Company. Without limiting any of the foregoing, Employee shall
assist Company in every way deemed necessary or desirable by Company (but at the
Company's expense) to obtain and enforce patents, copyrights, trademarks and
other rights and protections relating to any Confidential Information and
Inventions in any and all countries, and to that end Employee will execute all
documents for use in obtaining and enforcing such patents, copyrights,
trademarks and other rights and protections as Company may desire, together with
any assignments thereof to Company or persons designated by it. If Company is
unable for any reason to secure Employee's signature to any document required to
apply for or execute any patent, copyright, maskwork or other applications with
respect to any Inventions (including improvements, renewals, extensions,
continuations, divisions or continuations in part thereof), Employee hereby
irrevocably designates Company and its duly authorized officers and agents as
Employee's agents and attorneys-in-fact and on Employee's behalf to execute and
file any such application and to do all other lawfully permitted acts to further
the prosecution and issuance of patents, copyrights, maskworks or other rights
thereon with the same legal force and effect as if executed by Employee.
Employee's obligation to assist the Company shall continue beyond the
termination of Employee's employment, but Company shall compensate employee at a
reasonable rate after Employee's or Employee termination for time actually spent
by Employee at the Company's request on such assistance.

Employee Inventions. Attached as Exhibit A is a list of all Inventions and
information created, discovered, or developed by Employee whether or not
patentable or Registrable under patent, copyright or similar statutes, made or
conceived or reduced to practice or learned by Employee, either alone or jointly
with others, excluding any Inventions, relating in any way to the Company's
business or demonstrably anticipated research and development that were made by
Employee prior to Employee's employment with the Company (the "Employee
Inventions"). Employee represents that Exhibit A is complete and contains no
confidential information. Employee understands that Employee has no rights in
any such Employee Inventions other that those listed on Exhibit A. If there is

                                       3
<PAGE>
nothing identified on Exhibit A or if "none" is indicated on Exhibit A, employee
represents that Employee has made no Employee Inventions as of the time of
signing this Agreement. Except as listed on Appendix A which is attached to this
Agreement, Employee will not assert any rights to any inventions, discoveries,
concepts or ideas, or improvements thereof or know-how related thereto, as
having been made or acquired by Employee prior to being employed by the Company,
or since then, and not otherwise covered by the terms of this Agreement.

No Conflicts With Prior Obligations. Employee hereby represents and warrants
that Employee's employment by the Company and Employee's performance of
Employee's obligations under this Agreement will not conflict with any
obligations of any nature or type that Employee has or may have to any third
party or third parties. Employee will not disclose to Company or use in
Company's behalf any confidential or proprietary information belonging to a
third party, unless the third party has consented to the disclosure or use of
the information.

Covenant Not to Solicit. For a period of one (1) year from the date of any
termination of Employee's employment with the Company for any reason:

Employee shall not solicit for employment, attempt to employ, or assist any
other person or entity in employing or soliciting for employment, any employee
or representative of Company, either for Employee or for any other entity; and

Employee shall not solicit or influence or attempt to solicit or influence any
client of the Company, customer of the Company or other person who may become a
client or customer of the Company, either directly or indirectly, in any way
that directs or is intended or is likely to direct or cause such actual or
potential client, customer or other person not to purchase the Company's
products and /or services.

Equitable Remedies. Employee acknowledges that breach of this Agreement would
cause Company to suffer irreparable harm for which monetary damages would be
inadequate compensation. Employee agrees that Company will be entitled to an
injunction restraining any actual or threatened breach of this Agreement, or
specific performance, if applicable, in addition to any monetary damages.

Employment Relationship. The employment relationship between Employee and the
Company is governed by the Employment Agreement and , as applicable, this
Agreement.

Entire Agreement. This Agreement and the Employment Agreement to which this
Agreement is attached as an exhibit set forth the entire agreement of the
parties with respect to the subject matter hereof, and supersedes all prior
agreements, whether written or oral.

Waiver and Amendment. This Agreement may be amended only by a writing signed by
both parties hereto. No oral waiver, amendment or modification of this Agreement
shall be effective under any circumstances. The waiver by the Company of a
