NOTE 1 - CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

          The accompanying financial statements have been prepared by the
          Company without audit. In the opinion of management, all adjustments
          (which include only normal recurring adjustments) necessary to present
          fairly the financial position, results of operations and cash flows at
          March 31, 2000 and 1999 and for all periods presented have been made.

          Certain information and footnote disclosures normally included in
          financial statements prepared in accordance with generally accepted
          accounting principles have been condensed or omitted. It is suggested
          that these condensed financial statements be read in conjunction with
          the financial statements and notes thereto included in the Company's
          September 30, 1999 audited financial statements. The results of
          operations for periods ended March 31, 2000 and 1999 are not
          necessarily indicative of the operating results for the full years.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

     General. The Company has formulated its business plans and strategies based
on certain assumptions of the Company's management regarding the size of the
market for the products which the Company will be able to offer, the Company's
anticipated share of the market, and the estimated prices for and acceptance of
the Company's products. The Company continues to believe its business plans and
the assumptions upon which they are based are valid. Although these plans and
assumptions are based on the best estimates of management, there can be no
assurance that these assessments will prove to be correct. No independent
marketing studies have been conducted on behalf of or otherwise obtained by the
Company, nor are any such studies planned. Any future success that the Company
might enjoy will depend upon many factors, including factors which may be beyond
the control of the Company or which cannot be predicted at this time. These
factors may include product obsolescence, increased levels of competition,
including the entry of additional competitors and increased success by existing
competitors, changes in general economic conditions, increases in operating
costs including cost of supplies, personnel and equipment, reduced margins
caused by competitive pressures and other factors, and changes in governmental
regulation imposed under federal, state or local laws.

     The Company's operating results may vary significantly due to a variety of
factors including changing customers profiles, the availability and cost of raw
materials, the introduction of new products by the Company or its competitors,
the timing of the Company's advertising and promotional campaigns, pricing
pressures, general economic and industry conditions that affect customer demand,
and other factors.

     Results of Operations (Six Months Ended March 31, 2000 Compared to Six
Months

<PAGE>   15

Ended March 31, 1999). During the 1999 fiscal year and the first half of the
2000 fiscal year the focus of the Company's efforts was on development,
manufacturing and distribution of the Company's hardware products. The immediate
focus has been on the DAF (Dissolved Air Flotation), Automatic Back-Flush
Filtration System, O-Zone Mixing Chamber and other related products, some of
which have their own separate markets.

     The Company is continuing its engineering focus on hardware and water
filtration equipment. The first phase of testing was completed in November 1998.
The second phase of testing was completed in April 1999 and has revealed useful
data. Final testing began in January 2000 for the first production unit.
Management is implementing engineering changes prior to the execution of
contracts for production tooling. Management is in negotiations with suppliers
for tooling and production of various support products, and is also negotiating
with an existing manufacturing company for the establishment of a joint venture
to handle most aspects of production, distribution and service.

     For the six months ended March 31, 2000, the Company reported a loss of
$547,646, or $.01 per share. This compares with a loss of $281,932, or $.00 per
share, for the six months ended March 31, 1999. The increase in the loss is
principally due to higher administrative and marketing costs incurred as the
Company nears production.

     Liquidity and Capital Resources. On March 31, 2000 the Company had cash and
cash equivalents of approximately $856,646. The principal source of liquidity
has been sales of securities. Management anticipates that additional capital
will be required to finance the Company's operations. The Company believes that
expected cash flow from operations plus the anticipated proceeds from sales of
securities will be sufficient to finance the Company's operations at currently
anticipated levels for a period of at least twelve months. However, there can be
no assurance that the Company will not encounter unforeseen difficulties that
may deplete its capital resources more rapidly than anticipated.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

     In June 1999 the Company filed an action against Jack Moorehead, Dascore,
LLC, S. Donna Friedman and certain others in the U.S. District Court for the
Southern District of California (Case No. 99-cv-1201-K-LSP). Moorehead is the
former President of the Company, and Dascore LLC is an entity controlled by him
and in a business related to that of the Company. S. Donna Friedman is a former
officer and director of the Company.

     The Complaint alleges, among other things, that the defendants have
infringed and continue to infringe on certain patents owned by the Company, and
that they are

<PAGE>   16

familiar with the Company's intellectual property through their past positions
with the Company. The Complaint also alleges that the defendants have sold or
attempted to sell technology owned by the Company and covered by the Company's
patents, and that the defendants are unfairly competing with the Company by
exploiting its technology without payment. In addition, the action includes
claims of false advertising, in that the defendants are falsely representing
that they own the technology; interference with economic relations and
interference with prospective advantage, relating to the effect that the
defendants' conduct has had on the Company's dealings with third parties; and
misappropriation of trade secrets learned by the defendants while associated
with the Company. The complaint further alleges that the defendants conspired to
convert technology, money and equipment owned by the Company, and used Company
funds to pay personal expenses. Finally, the complaint alleges that Moorehead
and Friedman defrauded the Company and breached their fiduciary duties to the
Company in connection with their departure from the Company and their retention
of property of the Company.

     One of the defendants, Jack Moorehead, has asserted a cross-complaint
against the Company based on a breach of contract cause of action. The case is
currently in the discovery stage.

Item 2. Changes in Securities and Use of Proceeds

     During the period of six months ended March 31, 2000, the Company sold
10,303,505 shares of its Common Stock to approximately 136 investors, at a price
of $.10 per share. The Company believes all of such sales were exempt from the
registration requirements of the Securities Act of 1933, as amended, by virtue
of Section 4(2) thereof and Regulation D thereunder.

Item 3. Defaults upon Senior Securities.
