                                     NOTES TO THE UNAUDITED FINANCIAL STATEMENTS
                                                          JUNE 30, 2001 AND 2000
--------------------------------------------------------------------------------

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 (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, 2000.

NOTE 3 - RECENT PRONOUNCEMENTS

In January 2001, the Financial Accounting Standards Board Emerging Issues Task
Force issued EITF 00-27 effective for convertible debt instruments issued after
November 16, 2000. This pronouncement requires the use of the intrinsic value
method for recognition of the detachable and imbedded equity features included
with indebtedness, and requires amortization of the amount associated with the
convertibility feature over the life of the debt instrument rather than the
period for which the instrument first becomes convertible. Management is in the
process of evaluating the requirements of EITF 00-27, but does not expect this
pronouncement will materially impact the Company's financial position or results
of operations.

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.

                                                   (A DEVELOPMENT STAGE COMPANY)
                                     NOTES TO THE UNAUDITED FINANCIAL STATEMENTS
                                                          JUNE 30, 2001 AND 2000
--------------------------------------------------------------------------------

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.

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.


NOTE 4 -  COMMON STOCK

During the nine month period ended June 30, 2001, the Company issued 1,930,000
shares of common stock for cash at a price of $.10 per share to private
investors. In addition, 295,492 shares of common stock were issued to
independent contractors for various services at prices of $.10 - $.28. Lastly,
in connection with the Company's registration statements on Form S-8, 1,400,000
shares of common stock were issued to consultants at $.22 per share for a total
amount of $308,000, for the services to be provided through December 2001. The
Company has amortized $154,000 of consulting fees through June 30, 2001.

NOTE 5 - SHARES TO BE ISSUED

The Company received cash of $392,500 for 3,925,000 shares of common stock to be
issued subsequent to the period ended June 30, 2001. In addition, the Company
received the services amounting $35,115 for 325,460 shares of common stock to be
issued subsequent to the period ended June 30, 2001. In that regard, through
July 12, 2001, the Company has issued 3,775,000 shares of common stock.

NOTE 6 - EARNING PER SHARE

Earnings per share for the three and nine month periods ended June 30, 2001 and
2000 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.

The following table reconciles the number of shares used in the basic and
diluted earnings per share calculations (in millions):

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

General
-------

         Results of Operations (Three Months Ended June 30, 2001 Compared to
         -------------------------------------------------------------------
Three Months Ended June 30, 2000).
----------------------------------

         General and administrative expenses in the three months ended June 30,
2001 decreased by $429,955, from $809,659 in the prior period to $379,704 in the
current period. The decrease is principally due to non-cash expenses for the
prior period relating to stock compensation to officers and employees; no stock
compensation was paid to officers or employees during the current period, as
they became subject to a stock option plan. Also, legal fees decreased due to
reduced levels of activity in the pending litigation during the current period,
as compared with the prior period. Research and development costs for the
quarter were $13,136, principally for production drawings by an outside
contractor; there were no such expenses in the June 30, 2000 period. Net loss
for the quarter decreased by $417,938, principally due to the lack of stock
compensation in the current quarter and, to a lesser degree, the reduction in
legal fees.

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

         On June 30, 2001, the Company had cash and cash equivalents of
approximately $325,829, although $140,000 of that amount is 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 June 30, 2001, the Company had an accumulated deficit of
$9,249,160. 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 new business enterprise, many of which the Company cannot
control.

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

                                       10
<PAGE>

for the Southern District of California (Case No. 99-cv-1201-L-NLS). Moorehead
is the former President of the Company, and Dascore LLC is an entity that is 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 certain patents owned by the
Company, and that they are familiar with the Company's intellectual property
through their past positions with the Company.

         In April, 2001 the Company entered into a settlement agreement in open
court with certain defendants, including Moorehead, under which the defendants
are to return approximately 7,800,000 shares of the Company's Common Stock held
by them for cancellation. In addition, Moorehead and the other defendants waived
any claims to the Company's patents, agreed to refrain from infringing patents
owned and/or developed by the Company, and agreed to refrain from using the
Company's technology developed while Mr. Moorehead was associated with the
Company.

         Following the settlement, the defendants alleged that no settlement
agreement existed. The Company filed a motion to enforce the Settlement
Agreement, and in early August the court ruled that the Settlement Agreement is
binding. That ruling is subject to appeal.

         If it becomes final, the settlement resolves all patent and technology
issues among the parties, with the exception of patent no. 6,035,240, which
remains in dispute between the Company and Dascore. That patent concerns data
acquisition, such as monitoring the quality of water, water pressure and any
number of other monitoring or control issues.

         The Company also settled an action in which it was a defendant, Barnett
v. Sionix Corporation, filed in Orange County Superior Court, (Case No.
00CC05463). The complaint sought repayment of approximately $150,000 in alleged
loans by the plaintiff, who is the mother-in-law of the former Chief Executive
Officer of the Company, Michael Taylor. The Company had cross-complained against
the plaintiff and Mr. Taylor for breach of fiduciary duty relating to the
alleged loans. Under the settlement, the Company will retain those shares of
stock that Michael Taylor had previously voluntarily returned to the Company,
and the Company and Michael Taylor waive any additional claims against each
other, including claims for loans Michael Taylor asserts he made to the Company
while Taylor was Chief Financial Officer. Barnett agreed to substantially reduce
her claims against the Company and the Company agreed to a repayment schedule of
the reduced sum.

         The Company is the plaintiff in a pending 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. GIC 754391), and a separate action against Wenthur & Chachas,
its previous corporate counsel, and the individual attorneys in those firms (San
Diego County Superior Court Case No. GIC 747267). The action against the patent
attorneys alleges that the patent attorneys represented the Company and
Moorehead contemporaneously and failed to advise the corporation of the inherent
conflict of interest in representing both parties. The action further alleges
the patent attorneys aided Moorehead and others in misappropriating the
Company's intellectual property and trade secrets. The action seeks monetary
damages, attorneys fees and interest.

                                       11
<PAGE>

         The action against the former corporate counsel seeks damages arising
out of their alleged creation of false documents to defraud the corporation with
respect to certain intellectual property rights and securities transactions. The
defendants in that action have filed a motion for summary judgment, which was
granted in August, 2001. The Company plans to appeal the ruling.

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 June 30, 2001 in transactions not registered under
the Securities Act of 1933:

         During the three months ended June 30, 2001 the Company issued
4,175,000 shares of Common Stock to private investors for cash in a private
placement. In addition, the Company issued 314,862 shares to two individuals for
services rendered. 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

         None.

Item 4. Submission of Matters to a Vote of Security Holders
