NOTE 1 - BUSINESS ACTIVITY

Sionix Corporation (the "Company") was incorporated in Utah in 1985. The Company
was formed to design, develop, and market an automatic water filtration system
primarily for small water districts.

The Company is in the development stage and its efforts have been principally
devoted to research and development, organizational activities, and raising
capital.

NOTE 2 - BASIS OF PRESENTATION

The accompanying unaudited financial statements of Sionix Corporation have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
required by generally accepted accounting principles 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 interim periods are not necessarily
indicative of the results for any future period. These statements should be read
in conjunction with the Company's audited financial statements and notes thereto
for the year ended September 30, 2001.

NOTE 3 - RECENT PRONOUNCEMENTS

On July 20, 2001, the FASB issued SFAS No. 141, "Business Combinations," and
SFAS No. 142, "Goodwill and Other Intangible Assets." These statements make
significant changes to the accounting for business combinations, goodwill, and
intangible assets.

SFAS No. 141 establishes new standards for accounting and reporting requirements
for business combinations and will require that the purchase method of
accounting be used for all business combinations initiated after June 30, 2001.
Use of the pooling-of-interests method will be prohibited. This statement is
effective for business combinations completed after June 30, 2001.

SFAS No. 142 establishes new standards for goodwill acquired in a business
combination and eliminates amortization of goodwill and instead sets forth
methods to periodically evaluate goodwill for impairment. Intangible assets with
a determinable useful life will continue to be amortized over that period. This
statement becomes effective January 1, 2002.

In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 143, "Accounting for Asset
Retirement Obligations". SFAS 143 addresses financial accounting and reporting
for obligations associated with the retirement of tangible long-lived assets and
the associated asset retirement costs. This Statement is effective for financial
statements issued for fiscal years beginning after June 15, 2002.

SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets,"
was issued in August 2001. SFAS No. 144 is effective for fiscal years beginning
after December 15, 2001, and addresses financial accounting and reporting for
the impairment or disposal of long-lived assets. This statement supersedes SFAS
No. 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," and the accounting and reporting provisions of APB
Opinion No. 30, "Reporting the Results of Operations - Reporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently
Occurring Events and Transactions," for the disposal of a segment of a business.

The adoption of above pronouncements, did not materially impact the Company's
 financial position or results of operations.

NOTE 4 - COMMON STOCK

During the six months period ended March 31, 2002, the Company issued 3,547,000
shares of common stock for cash at a price of $.10 per share, including 100,000
shares for cash of $10,000 received in the prior year. 100,000 shares of common
stock were issued for contribution at a price of $.11 per share. The Company
issued 18,838 shares for compensation to an employee at $.15 per share. The
Company issued 92,929 shares for services received totaling $13,990. The Company
issued 639,509 shares in the first quarter for debts of $103,294 settled in the
prior year.

                                       7
<PAGE>

According to a legal settlement, the Company cancelled 7,533,701 shares of
common stock issued to the former president and the director (Note 8). No gain
or loss was recorded from this transaction since the transaction was recorded at
par value at the time of issuance and reversed the recording of the issuance of
the stock at par value.

NOTE 5 - SHARES TO BE ISSUED

The Company received cash of $44,500 for 445,000 shares of common stock to be
issued subsequent to the period ended March 31, 2002.

NOTE 6 - EARNINGS PER SHARE

Earnings or loss per share for the three month periods ended March 31, 2002 and
2001 were determined by dividing net income for the periods by the weighted
average number of both basic and diluted shares of common stock and common stock
equivalents outstanding. Stocks to be issued are regarded as common stock
equivalents and are considered in diluted earnings per share calculations.

Weighted average number of shares used to compute basic and diluted loss per
share is the same since the effect of dilutive securities is anti-dilutive.

NOTE 7 - RECLASSIFICATIONS

Certain prior period amounts have been reclassified to conform to the period
ended March 31, 2002 presentation.

NOTE 8 - LEGAL SETTLEMENTS

A malpractice case brought by the Company against its former counsel, Wenthur
and Chachas, was settled in January 2002 for a $20,000 payment by the Company.
The Company has recorded $50,000 (the difference between $70,000, the amount
previously reserved, and the actual settlement amount) as a gain on settlement
in the financial statement.

An action was filed by the Company for professional negligence, malpractice,
breach of fiduciary duty and breach of contract against Gilliam, Duncan & Harms,
its previous patent counsel. The complaint alleged that the patent attorneys
represented the Company and Jack Moorehead, former President of the Company,
contemporaneously and failed to advise the corporation of the inherent conflict
of interest in representing both parties. The action further alleged the patent
attorneys aided Moorehead and others in misappropriating the Company's
intellectual property and trade secrets. The action went to trial, and in
December 2001 a minute order was issued announcing a judgment in favor of Sionix
against the defendants. The judgment is still subject to appeal. One of the
principal defendants in the case has filed bankruptcy, and the Company has filed
a motion to establish that the obligation to the Company is not dischargeable in
bankruptcy.

The Company is the defendant in a collection action brought by a law firm that
had previously represented it, Murphey & Murphey v. Sionix Corporation. The law
firm seeks collection of approximately $156,000 in legal fees. The Company has
filed a cross-complaint alleging, among other things, malpractice and breach of
fiduciary duty. The Company intends to vigorously contest the action. The legal
fees have been accrued in the financial statements.

Extraordinary gain:

The lawsuit which had been filed by the Company against its former President,
Dascore, LLC, an entity controlled by the former President and in a business
related to that of the Company; and a former officer and director of the Company
(the "Defendants"), was settled. The Company alleged that the Defendants had (1)
infringed on certain patents owned by the Company, through knowledge gained in
their former positions; (2) sold or attempted to sell technology owned by the
Company and covered by patents; (3) conspired to convert technology, money and
equipment owned by the Company to pay personal expenses, and (4) defrauded the
Company and breached their fiduciary duties in connection with their departure
by retention of property owned by the Company. As a result of this settlement,
the Company recorded a receivable of $79,999 for the settlement award. The
Company recorded $17,618 as an extraordinary gain for the reduction amount of
note payable as per the settlement. In addition, all of outstanding shares of
Common Stock held by the defendants were returned and cancelled.

Item 2.     Management's Discussion and Analysis or Plan of Operation

General
-------

         Results of Operations (Three Months Ended March 31, 2002 Compared to
         -----------------------------------------------------------------------
Three Months Ended March 31, 2001).
--------------------------------------

         General and administrative expenses in the three months ended March 31,
2002 decreased by $34,301, from $243,001 in the prior period to $208,700 in the
current period. The increase is principally due to decreased legal fees in the
current period because of the resolution of various litigation matters during
the current period. No research and development costs were incurred during the
current quarter, compared to $156,643 during the prior period, reflecting the
advanced state of development of the Company's products in the current period.
Net loss for the quarter decreased $346,943. This decrease was principally due
to income from a legal settlement, an extraordinary gain on the settlement of
debts, and the lack of research and development expenses during the period.

        Liquidity and Capital Resources.
        -------------------------------

         On March 31, 2002, the Company had cash and cash equivalents of
approximately $69,818. The principal source of liquidity has been sales of
securities and, to a lesser extent, the settlement of legal claims. Management
anticipates that additional capital will be required to finance the Company's
operations. The Company believes that anticipated proceeds from sales of
securities and other financing activities, plus possible cash flow from
operations towards the end of the fiscal year, will be sufficient to finance the
Company's operations. However, the Company has no commitments for financing, and
there can be no assurance that such financing will be available or that the
Company will not encounter unforeseen difficulties that may deplete its capital
resources more rapidly than anticipated. Also, the Company may not be able to
generate revenues from operations during the fiscal year.

         As of March 31, 2001, the Company had an accumulated deficit of
$10,007,800. It can be expected that the future operating results will continue
to be subject to many of the problems, expenses, delays and risks inherent in
the establishment of a developmental business enterprise, many of which the
Company cannot control.

         The Company is the plaintiff in an action for professional negligence,
malpractice, breach of fiduciary duty and breach of contract against Gilliam,
Duncan & Harms, its previous patent counsel (San Diego County Superior Court,
Case No. GIC754391). The complaint alleged that the patent attorneys represented
the Company and Jack Moorehead, former President of the Company,
contemporaneously and failed to advise the corporation of the inherent conflict
of interest in representing both parties. The action further alleged the patent
attorneys aided Moorehead and others in misappropriating the Company's
intellectual property and trade secrets. The action went to trial, and in
December 2001 a minute order was issued announcing a judgment in favor of Sionix
against the defendants in the amount of $525,962. The judgment is still subject
to appeal. One of the principal defendants in the case has filed bankruptcy, and
the Company has filed a motion to establish that the obligation to the Company
is not dischargeable in bankruptcy.

         The Company is the defendant in a collection action brought by a law
firm that had previously represented it, Murphey & Murphey v. Sionix Corporation
(San Diego Superior Court, North County Division, Case No. GIN 019186). The law
firm seeks collection of approximately $156,000 in legal fees. The Company has
filed a cross-complaint alleging, among other things, malpractice and breach of
fiduciary duty. The Company intends to vigorously contest the action.

Item 2.    Changes in Securities and Use of Proceeds

         The following is a description of securities issued by the Company
during the three months ended March 31, 2002 in transactions not registered
under the Securities Act of 1933:

         The Company issued 13,843 shares to a single attorney for legal
services rendered.

         The Company issued 2,592,000 shares to twenty-four investors in a
private placement, at a price of $.10 per share.

         The Company believes each of the foregoing transactions was exempt by
virtue of Section 4(2) from the registration requirement of the Securities Act
of 1933.
