Total Principal Amount: $75,000                               Date July 19, 2007

FOR VALUE RECEIVED, the undersigned, American Soil Technologies, Inc., a Nevada
corporation (the "Company"), hereby promises to pay to the order of Norma L.
Minna located at 14150 Enadia Way, Van Nuys, CA 91405 or assigns (the "Holder"),
in lawful money of the United States of America, and in immediately payable
funds, the principal sum of seventy five thousand dollars ($75,000), with
interest thereon, both before and after default until paid, at the rate of ten
percent (10%) per annum, upon the terms and conditions set forth herein. The
Holder may agree to accept interest payments in Common Shares.

     1. MATURITY DATE/INTEREST PAYMENTS. The Company shall pay to the Holder
monthly interest payments in cash with the first payment due on August 18, 2007.
Upon conversion of this Debenture as allowed in this Agreement, all accumulated
but unpaid interest shall be extinguished. This Debenture shall mature and all
principal and accrued interest shall be fully due and payable by the Company to
Holder on July 18, 2009 the "Maturity Date"). Interest shall be computed on the
actual days in a year and the actual number of days elapsed.

     2. CONVERTIBILITY. This Debenture may be converted by the Holder at any
time beginning upon execution of this Debenture and ending upon the Maturity
Date at a conversion rate of one (1) share of Company Common Stock (the
"Shares") per an amount equal to the closing price of the stock on the day
immediately preceding the date of this Debenture. The conversion rate for this
<PAGE>
debenture is nineteen cents per share ($0.19). No accrued interest will be paid
upon conversion. The Shares to be issued upon conversion shall not be subject to
any liens, security interests, pledges, encumbrances, charges, restrictions,
demands or claims of any other party whatsoever. Company shall use its best
efforts to expeditiously file with and have declared effective by the Securities
and Exchange Commission a registration statement in an appropriate form to
register the Shares issuable upon conversion of this Debenture to ensure that
Company will have freely tradable stock available to Holder in the event Holder
elects to convert this Debenture to Shares.

     3. WARRANT. The Holder shall have the right for value received, subject to
the terms and conditions set forth in the Warrant Agreement attached hereto as
Exhibit A, to purchase, shares of common stock of the Company (the "Warrant
Shares") upon exercise at a purchase price of thirty cents ($0.30 ) per share
(the "Warrant Price"). Said Warrant Shares shall be the same amount as the
number of shares that may be converted

     4. PREPAYMENT. The Company may prepay this Debenture prior to the Maturity
Date and prior to the receipt of a conversion election, in whole or in part, at
any time.

     5. TRANSFERABILITY. This Debenture shall be freely transferable by the
Holder provided such transfer is in compliance with applicable federal and state
securities laws.

     6. TERMINATION. Holder may terminate funding this Debenture immediately
upon the occurrence of any of the following events:

     a.   Bankruptcy of the Company;

     b.   Serious violations (SEC, Reporting, or other) that would adversely
          affect the Company's publicly traded stock; or

     c.   A prohibition against selling Company product(s) (polymer) in the
          United States.

     7. DEFAULT. In the event of the Company's failure to pay the principal and
interest due hereunder within ten (10) days following the Maturity Date, Holder
shall have the option, by written notice to the Company, to declare the unpaid
principal amount due to Holder, together with all accrued interest thereon,
immediately due and payable. In the event Company fails to cure the default
within twenty (20) days of the date of receipt of the written notice by Holder,
Holder may pursue any legal remedy available to Holder.

     8. NOTICES. Notices to be given hereunder shall be in writing and shall be
deemed to have been sufficiently given if delivered personally or sent by
overnight courier or messenger or sent by registered or certified mail (air mail
if overseas), return receipt requested, or by telex, facsimile transmission,

mail, return receipt requested, shall be deemed to have been received on the
fifth business day after the date of mailing. The Parties shall give written
notice of any change of address to each other.

     9. INVESTOR STATUS. By providing the principal amount(s) set forth in this
Debenture, Holder acknowledges and certifies that this Debenture represents a
highly speculative investment and that Holder's personal financial situation is
such that (i) Holder can afford to hold the Debenture for an indefinite period
of time and to sustain a complete loss of this investment, and (ii) Holder has
adequate means of providing for Holder's current needs and possible
contingencies and has no need for liquidity in this investment in the Company.
By virtue of Holder's knowledge and experience in financial and business
matters, Holder is capable of evaluating the merits and risks of an investment
in the securities.

     Holder, if a corporation, partnership, trust or other form of business
entity, (i) is authorized and otherwise duly qualified to purchase and hold the
Debenture, (ii) has obtained such additional tax and other advice that it has
deemed necessary, and (iii) has not been formed for the specific purpose of
acquiring the Debenture.

     Holder consents to the affixing by the Company of such legends on
certificates representing the securities as any applicable federal or state
securities law may require from time to time. Holder further acknowledges and
certifies that in evaluating the suitability of an investment in the Company,
Holder has relied on Holder's own independent investigations and has not relied
upon any representations or other information (whether oral or written) from the
Company, and its officers, directors, agents, employees or representatives.
Holder acknowledges that in making the decision to invest in the Company, Holder
has, prior to any purchase of the securities, been given the information on the
Company, its business, and its financials, had access and opportunity to examine
this offer, and had an opportunity to ask questions of, and to receive answers
from, the Company or any person acting on its behalf concerning the terms and
conditions of this offering. Holder has been furnished with access to all
publicly available materials relating to the business, finances, and operations
of the Company and material relating to the offer and sale of the securities,
which have been requested. Holder has received complete and satisfactory answers
to any such inquiries. Holder acknowledges that Holder has not received any
formal disclosure document regarding this investment, and Holder is an
accredited investor as defined in Rule 501 of Regulation D of the Securities Act
of 1933, as amended.

                                       3

     10. GOVERNING LAW. This Debenture shall be governed by and construed and
interpreted in accordance with the laws of the state of California applicable to
contracts made and to be performed entirely therein, without giving effect to
the rules and conflicts of law.

     11. ATTORNEYS FEES. In the event of default by the Company requiring the
Holder or any assignee thereof to refer this Debenture to an attorney for
collection, the Company agrees to pay all reasonable costs and expenses incurred
in attempting or effecting collection hereunder, including reasonable attorney's
fees, whether or not suit is instituted.

     12. MODIFICATION. This Debenture may be modified or amended only by an
agreement in writing signed by the party against whom the agreement is sought to
be enforced.

     13. CONFORMITY WITH LAW. All agreements between the Company and Holder are
expressly limited, so that in no event or contingency whatsoever, whether by
reason of the advancement of the proceeds of this Debenture, acceleration of
maturity of the unpaid principal balance, or otherwise, shall the amount paid or
agreed to be paid to Holder of this Debenture for the use, forbearance, or
detention of the money to be advanced under this Debenture exceed the highest
lawful rate permissible under applicable usury laws. If, under any circumstances
whatsoever, fulfillment of any provision of this Debenture or any other
agreement pertaining hereto, after timely performance of such provision is due,
shall involve transcending the limit of validity prescribed by law which a court
of competent jurisdiction deems applicable, then, ipso facto, the obligations to
be fulfilled shall be reduced to the limit of such validity, and if, under any
circumstances whatsoever, Holder shall ever receive as interest an amount that
exceeds the highest lawful rate, the amount that would be excessive interest
shall be applied to the reduction of the unpaid principal balance under this
Debenture and not to the payment of interest, or, if such excessive interest
exceeds the unpaid balance of principal under this Debenture, such excess shall
be refunded to Company. This provision shall control every other provision of
all agreements between Company and Holder.

either in the event that a registration statement covering the resale of the
Warrant Shares and naming the Holder as a selling stockholder thereunder is not
then effective or the Warrant Shares are not freely transferable without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act of
1933, as amended (the "Securities Act"), or (ii) if this Warrant shall have been
issued pursuant to a written agreement between the original Holder and the

to receive Warrant Shares shall be deemed to have become holder of record of
such Warrant Shares as of the Date of Exercise of this Warrant.

this Warrant (or any New Warrant, as applicable), with the Form of Election to
Purchase attached hereto (or attached to such New Warrant) appropriately

of Warrant Shares so indicated by the holder hereof to be purchased.

3. PIGGYBACK REGISTRATION RIGHTS. The Holder is granted rights of registration
in that said warrant shall be included in the Company's next registration. The

The Company will pay all registration expenses in connection therewith.

times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Holder. The Company covenants that all Warrant
Shares that shall be so issuable and deliverable shall, upon issuance and the
payment of the applicable Exercise Price in accordance with the terms hereof, be
duly and validly authorized, issued and fully paid and nonassessable.

5. PAYMENT OF EXERCISE PRICE. The Holder shall pay the Exercise Price in cash.

hereto and their respective successors and assigns. This Warrant may be amended

exclusive benefit of the Company and the Holder.

the relative rights of the Company and its stockholders.

unenforceable in any respect, the validity and enforceability of the remaining
terms and provisions of this Warrant shall not in any way be affected or
impaired thereby and the parties will attempt in good faith to agree upon a
valid and enforceable provision which shall be a commercially reasonable
substitute therefore, and upon so agreeing, shall incorporate such substitute
provision in this Warrant.

by its authorized officer as of the date first indicated above.
