                          NOTE TO FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 1 - BASIS OF PRESENTATION
------------------------------

The accompanying unaudited financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Rule 10-01 of Regulation S-X. Accordingly, they do
not include all of the information and notes required by accounting principles
generally accepted in the United States of America for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring adjustments) considered necessary for a fair presentation have been
included. Operating results for the nine-month period ended April 30, 2002 are
not necessarily indicative of the results that may be expected for the year
ended July 31, 2002. For further information, please refer to the consolidated
financial statements and notes thereto included in the Company's Annual Report
on Form 10-KSB for the year ended July 31, 2001.

NOTE 2 - ORGANIZATION, LINE OF BUSINESS AND SIGNIFICANT BUSINESS RISKS
----------------------------------------------------------------------

Organization and Line of Business
---------------------------------

American Technologies Group, Inc. (the "Company" or "ATG"), a Nevada
corporation, is engaged in the development, commercialization and sale of
products and systems using its patented and proprietary technologies. The
resulting products are intended to offer cost-effective solutions to reduce, and
in some cases eliminate, hazardous chemical by-products or emissions resulting
from industrial and combustion processes. The Company's proprietary catalyst
technology may improve many commercial products including detergents and
cosmetics.

The Company has suspended substantive operations subsequent to July 31, 2001.
Management is currently pursuing various options to obtain additional funding,
including the sale and/or license of certain technologies to related and other
parties, and the sale of a majority equity position to investors with a
different business plan.

Significant Business Risks
--------------------------

Since its inception, the Company has incurred significant operating losses. The
ability of the Company to operate as a going concern is dependent upon its
ability (1) to obtain sufficient additional debt and/or equity capital, and (2)
generate significant revenues through its existing assets and operating
business. The Company plans to raise additional working capital through private
offerings of debt and equity. The successful outcome of future activities cannot
be determined at this time and there are no assurances that if achieved, the
Company will have sufficient funds to execute its business plans or generate
positive operating results. These issues, among others, raise substantial doubt
about the ability of the Company to continue as a going concern. The financial
statements do not include any adjustments relating to the recoverability and
classification of asset carrying amounts or the amount and classification of
liabilities that might result should the Company be unable to continue as a
going concern.

Net Income (Loss) Per Share
---------------------------

Net loss per common share is based upon the weighted average number of common
shares outstanding during the fiscal year under the provisions of Statement of
Financial Accounting Standards No. 128, "Earnings Per Share." Common share
equivalents were not considered as they either would be anti-dilutive or had no
impact on earnings per share for any periods presented. However, the impact
under the treasury method of dilutive stock options would have been incremental
shares of 32,186 and 409,439 for the nine months ended April 30, 2002 and 2001,
respectively.

Segments
--------

The Company operates in one business segment, technology products, as a result
of its sale of its mining business in fiscal 2000.

                          NOTE TO FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 3 - PROPERTY AND EQUIPMENT
-------------------------------

On August 25, 2000, the Company sold its land and buildings with a net book
value of approximately $950,000 to a third party in a sale-leaseback transaction
for total consideration of $1,300,000. As a result of the sale, the Company paid
its note payable of $877,500 with related accrued interest and recorded a
deferred gain of $286,125 on the sale. During the nine months ended April 30,
2001, the Company amortized $40,034 of the deferred gain. The deferred gain was
fully recognized later in fiscal 2001 when the lease converted to a
month-to-month lease.

In November 2001, the Company transferred ownership of its remaining property
and equipment with a net book value of $54,554. The property and equipment was
distributed to a creditor of the Company who is owed approximately $225,000 as
of April 30, 2002. The two parties have not yet determined the amount of the
liability that will be settled in connection with this transaction. Therefore,
the disposal has been recorded as a $54,554 loss on the accompanying statement
of operations.

NOTE 4 - NOTE PAYABLE - RELATED PARTY
-------------------------------------

In November 2001, the Company signed a promissory note with a third party who
has since become the Company's chief executive officer for $400,000. The note is
secured by the Company's water distiller patents and is due August 8, 2002. As
of April 30, 2002, the Company has a balance of $381,331 under the promissory
note. There can be no assurances that the lender will continue to lend amounts
up to the original commitment of $400,000. Borrowings bear interest at 9% per

ITEM 2   MANAGEMENT'S DISCUSSION AND ANALYSIS

As reported in the previous 10-Q for the period ended October 31, 2001, the
Company largely had ceased operations during the prior fiscal year and had begun
focusing efforts on restructuring and refinancing. In the nine months ended
April 30, 2002, the Company successfully continued these efforts to settle
various pending law suits, reduce outstanding liabilities, acquire an equity
funding facility to finance acquisition of new products, entities and
technologies, and otherwise strengthen the business.

In November 2001, the Company announced and signed a promissory note with Dr.
Gary Fromm for $400,000. These funds were to permit completion of audits
necessary for filing of the overdue 10-K and other efforts necessary to enable
the Company's restructuring program to proceed. In early February 2002 Lawrence
Brady resigned as Chairman and CEO of the Company to be replaced by Dr. Gary
Fromm. In February 2002, the Company filed with the SEC to send a proxy to
shareholders to increase authorized shares to enable an acquisition program to
proceed.

In the interim, the Company has continued to explore possibilities for licensing
and distributing the distiller for manufacture and sales in selected Asian
markets. The same is true for the Force products, which still find interested
customers both domestically and overseas. Efforts are underway to examine
strengthening the distribution network so as to increase sales. The acquisition
of new entities, technologies and products to create value for shareholders,
too, is underway in the form of evaluating possible investments.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, the Company has incurred significant operating losses. The
ability of the Company to operate as a going concern is dependent upon its
ability to (1) obtain sufficient additional capital and (2) generate significant
revenues through its existing assets and operating business. The Company plans
to raise additional working capital through private offerings of debt and
equity. The successful outcome of future activities cannot be determined at this
time and there are no assurances that if achieved, the Company will have
sufficient funds to execute its business plans or generate positive operating
results. These issues, among others, raise substantial doubt about the ability
of the Company to continue as a going concern.

Total assets decreased by $8,998 from the period ending January 31, 2002 to the
period ending April 30, 2002 largely due primarily to amortizing patents. Total
liabilities decreased by $75,778 from $6,265,444 to $6,189,666 at January 31,
2002 and April 30, 2002, respectively. This decrease was principally due to
various settlements of employee claims for payroll accruals.

The Company decreased the cash used in operations by $884,906 (from $1,270,538
to $385,632) for the nine months ended April 30, 2001 and April 30, 2002,
respectively, due almost exclusively to the reduction of personnel and
non-essential operating expenses.

In November 2001, the Company signed a promissory note with Dr. Gary Fromm for
$400,000. The note is secured by the Company's water distiller patents and is
due August 8, 2002. Through April 30, 2002, the Company has received
approximately $381,331 in borrowings under the promissory note. There can be no
assurances that the lender will continue to lend amounts up to the original
commitment of $400,000. Borrowings bear interest at 9% per annum with interest
payments due monthly.
