                         EXECUTIVE EMPLOYMENT AGREEMENT
           BETWEEN AMERICAN SOIL TECHNOLOGY, INC. AND RONALD SALESTROM


         This EXECUTIVE EMPLOYMENT AGREEMENT BETWEEN AMERICAN SOIL TECHNOLOGY,
INC. AND Ronald Salestrom (this "Agreement"), effective as of January 4, 2003
(the "Effective Date"), is entered into by and between AMERICAN SOIL TECHNOLOGY,
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."

         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:

         1.       Employment. The Company hereby employs Employee as the Chief
                  Technical Advisor 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 Schedule 1, and Employee shall
                  perform all other duties and activities that are assigned to
                  Employee by the President of the Company. Employee shall
                  report directly to and be supervised by the President or his
                  designee.

         2.       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.

         3.       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 two 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 1-year increments unless written notice is given by
                  either party within 60 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."

         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 gross salary shall be a
         credit against commissions received by Employee for sales to Gigot Agra
         in the percentages as set forth below.

                  the years 2003 and 2004 as long as the products are sold at
                  the Company's published prices.

         2.       5% thereafter as long as the products sold by Employee to
                  Gigot Agra are sold at the Company's published prices.

         3.       Commissions shall be deemed earned as of the date when the
                  Company receives the purchase price for a particular sale and
                  will be paid within fifteen (15) days of receipt of payment by
                  the Company.

         4.       There will be no discount to publish prices without express
                  written approval from the President of the Company.

                  (b) Sale Objectives. It is the Employee's sale objective to

         2003 and 2004 and not less than $3 million in 2005, $5 million in 2006
         and $7.5 million in 2007.

         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.

5.       Expenses.  Employee  is  authorized  to incur  expenses  in  reasonable
         amounts for promoting the business of the Company,  including  expenses

         detail  to  satisfy  the  information  requirements  of  ss.274  of the
         Internal Revenue Code of 1986, as amended.  The Company shall reimburse
         Employee  for all  reasonable  expenses  other than those  incurred  on
         behalf of Gigot Agra.  Specifically the reimbursable or direct expenses
         shall be as follows:

                  of the Company.

                  conducted to determine if the Company is entitled to any of
                  the proceeds if the equipment is sold in whole or in part.

6.       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

                  failure to perform; provided, however, that if Employee has
                  been provided written notice pursuant to this Section 9 on two

                  responsibilities in accordance with the Company's requirements
                  shall constitute Cause and the Company shall not be required

                  harassment, substance abuse, as such policies may be in effect
                  from time to time, if such violation of the Company's policy

         Employee under this Agreement.

            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, 2003 (the
"Effective Date"), is entered into by and between AMERICAN SOIL TECHNOLOGY,
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
TECHNOLOGY, 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,



<PAGE>

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.

1.       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.

2.       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, 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.

3.       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.

4.       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.

5.       Non-Competition.

         (a)      Acknowledgement. Employee acknowledges that (i) the Company is
                  engaged in a variety of business endeavors (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,


                                        2
<PAGE>

                  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.

         (b)      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 License Agreement
                  entered into between Employee and Employer has been
                  terminated.

                  (i)      "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 other than a Company
                           distributor.

                  (ii)     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.

                  (iii)    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. Employee shall
                           be permitted to accept employment with a distributor
                           of the Company and said employment shall not be a
                           breach of this "Covenant Not to Compete".

         (c)      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.

6.       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



                                        3
<PAGE>

         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."

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

         (b)      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.

         (c)      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.

7.       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.

8.       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.

9.       Employee Inventions. Attached as Schedule 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 Schedule 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 Schedule A. If there is nothing identified on Schedule A or
         if "none" is indicated on Schedule 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.

10.      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.

11.      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:

         (a)      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

         (b)      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.

12.      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.

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

15.      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 breach of any provision
         of this Agreement shall not operate or be construed as a waiver of any
         other or subsequent breach of this Agreement by Employee.

16.      Term of Agreement. This Agreement will remain in force during
         Employee's employment by the Company and will continue thereafter until

         public knowledge other than through a violation of this Agreement.

17.      Survival. The provisions of this Agreement shall survive termination or
         expiration of this Agreement and termination of the Employment
         Agreement, for any reason, for a period of 3 years after termination of
         the Term of the Employment Agreement.

18.      Successors and Assigns. This Agreement may not be assigned by Employee,
         but  the  Company  may  assign  any or all of  its  rights  under  this
         Agreement to any  affiliate or  subsidiary  company of the Company,  so
         long  as the  Company  remains  liable  for  the  performance  by  that
         affiliate  or  subsidiary  of the  payment  obligations  of the Company
         hereunder. Except as provided in the preceding sentence, this Agreement
         shall be binding  upon,  and inure to the  benefit  of, the parties and
         their respective personal representatives, successors and assigns.

19.      Severability. Should any provision of this Agreement be considered
         unenforceable by a court of law, the remainder of this Agreement shall
         remain in force to the fullest extent permitted by law.

20.      Governing Law. This Agreement shall be governed by and interpreted in
         accordance with the laws of the State of California, without giving
         effect to principles of conflicts of law. Employee hereby consents to
         the personal jurisdiction of the state and federal courts located in
         the State of California in connection with any litigation related to
         this Agreement and agrees that the exclusive venue for any such
         litigation shall be in such courts located in the State of California.
