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 the Company 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. The results for the three month period
ended December 31, 2001 are not necessarily indicative of the results to be
expected for the full fiscal year.

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 is effective January 1, 2002.

Management is in the process of evaluating the requirements of SFAS No. 141 and
142, but does not expect these pronouncements will materially impact the
Company's financial position or results of operations.

In October 2001, the FASB issued Statement of Financial Accounting Standards No.
144, Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS 144).
SFAS 144 supersedes SFAS 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of, and APB Opinion No. 30, Reporting

                                       7
<PAGE>

the Results of Operations - Reporting The Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions. SFAS 144 is effective for fiscal years beginning after December
15, 2001 and will carry forward many of the provisions of SFAS 121 and Opinion
30. Under SFAS 144, if a long-lived asset is part of a group that includes other
assets and liabilities, then the provisions of SFAS 144 apply to the entire
group. In addition, SFAS 144 does not apply to goodwill and other intangible
assets that are not amortized. Management does not expect the adoption of SFAS
144 to have a material impact on the results of operations or financial position
of the Company.

NOTE 4 - COMMON STOCK

During the three months period ended December 31, 2001, the Company issued
1,050,000 shares of common stock for cash at a price of $.10 per share. The
Company also issued 100,000 shares against cash received in the prior year of
$10,000. 100,000 shares of common stock were issued for a contribution amounting
to $11,300. The Company issued 18,838 shares for compensation to an employee at
$.15 per share. The Company issued 639,509 shares in the three month ended
December 31, 2001 for indebtedness of $103,294 settled in the prior year.

NOTE 5 - SHARES TO BE ISSUED

The Company received cash of $5,000 for 50,000 shares of common stock to be
issued subsequent to the period ended December 31, 2001. In addition, the
Company received services amounting to $12,040 for 79,086 shares of common stock
to be issued subsequent to the period ended December 31, 2001.

NOTE 6 - LOSS PER SHARE

Loss per share for the three month periods ended December 31, 2001 and 2000 were
determined by dividing net loss for the periods by the weighted average number
of both basic and diluted shares of common stock and common stock equivalents
outstanding. Shares 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 year amounts have been reclassified to conform to the fiscal year
2001 presentation.

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

General
-------

         Results of Operations (Three Months Ended December 31, 2001 Compared to
         -----------------------------------------------------------------------
Three Months Ended December 31, 2000).
--------------------------------------

         General and administrative expenses in the three months ended December
31, 2001 increased by $182,818, from $209,873 in the prior period to $392,691 in
the current period. The increase is principally due to higher legal fees in the
current period because of efforts to resolve several litigation matters that had
been pending for several years. Research and development costs for the quarter
were $22,300, a decrease of $19,098 from the prior period, reflecting the
advanced state of development of the Company's products.. Net loss for the
quarter increased by $155,112, principally due to the higher general and
administrative expenses offset by decreased research and development costs.

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

         On December 31, 2001, the Company had cash and cash equivalents of
approximately $105,044, although $40,000 of that amount was restricted, as it
secures a bond issued in a litigation matter. The principal source of liquidity
of the Company has been sales of securities. 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 December 31, 2001, the Company had an accumulated deficit of
$9,942,428. 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.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

         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,

                                       9
<PAGE>

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.

         The Company had also filed a separate action against two law firms that
had previously represented the Company in civil and corporate matters, Wenthur &
Chachas and Mitchell & Huston (San Diego County Superior Court Case No. GIC
747267). In August 2001, the court granted a summary judgement motion by the
defendants and thereafter entered judgment against the Company for attorneys'
fees and costs totaling $71,481. In January 2002 the Company entered into a
settlement agreement with the defendants, providing for a reduced payment in
full satisfaction of the judgment against the Company.

         The action against Mitchell and Huston alleged legal malpractice in
advising the Company on the settlement agreement with Wenthur & Chachas. The
case was settled in February 2002 when the defendants agreed to make a small
payment to the Company.

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 December 31, 2001 in transactions not registered
under the Securities Act of 1933:

         During the three months ended December 31, 2001 the Company issued (i)
1,050,000 shares of Common Stock to private investors for cash in a private
placement, at a price of $ .10 per share, (ii) 100,000 shares to private
investors for cash in a private placement received in the prior fiscal year,
(iii) 100,000 shares for a cash contribution of $11,300, (iv) 18,838 shares for
compensation to an employee, and (iv) 639,509 shares in cancellation of
obligations totaling $103,294, which took place in the prior year. 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.
