NOTE 1 - BUSINESS ACTIVITY

Sionix Corporation (the "Company") was incorporated 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 fiscal year ended September 30, 2003.

NOTE 3 - RECENT PRONOUNCEMENTS

On April 30, 2003, the FASB issued FASB Statement No. 149 ("SFAS 149"),
"AMENDMENT OF STATEMENT 133 ON DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES".
FAS 149 amends and clarifies the accounting guidance on (1) derivative
instruments (including certain derivative instruments embedded in other
contracts) and (2) hedging activities that fall within the scope of FASB
Statement No. 133 ("SFAS 133"), ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND
HEDGING ACTIVITIES. SFAS 149 also amends certain other existing pronouncements,
which will result in more consistent reporting of contracts that are derivatives
in their entirety or that contain embedded derivatives that warrant separate
accounting. SFAS 149 is effective (1) for contracts entered into or modified
after June 30, 2003, with certain exceptions, and (2) for hedging relationships
designated after June 30, 2003. The guidance is to be applied prospectively. The
adoption of SFAS No. 149 does not have a material impact on the Company's
financial position or results of operations or cash flows.

On May 15 2003, the FASB issued FASB Statement No. 150 ("SFAS 150"), ACCOUNTING
FOR CERTAIN FINANCIAL INSTRUMENTS WITH CHARACTERISTICS OF BOTH LIABILITIES AND
EQUITY. SFAS 150 changes the accounting for certain financial instruments that,
under previous guidance, could be classified as equity or "mezzanine" equity, by
now requiring those instruments to be classified as liabilities (or assets in
some circumstances) in the statement of financial position. Further, SFAS 150
requires disclosure regarding the terms of those instruments and settlement
alternatives. SFAS 150 affects an entity's classification of the following
freestanding instruments: a) Mandatorily redeemable instruments b) Financial
instruments to repurchase an entity's own equity instruments c) Financial
instruments embodying obligations that the issuer must or could choose to settle
by issuing a variable number of its shares or other equity instruments based
solely on (i) a fixed monetary amount known at inception or (ii) something other
than changes in its own equity instruments d) SFAS 150 does not apply to
features embedded in a financial instrument that is not a derivative in its
entirety. The guidance in SFAS 150 is generally effective for all financial
instruments entered into or modified after May 31, 2003, and is otherwise
effective at the beginning of the first interim period beginning after June 15,
2003. For private companies, mandatorily redeemable financial instruments are
subject to the provisions of SFAS 150 for the fiscal period beginning after
December 15, 2003. The adoption of SFAS No. 150 does not have a material impact
on the Company's financial position or results of operations or cash flows.

In December 2003, the Financial Accounting Standards Board (FASB) issued a
revised Interpretation No. 46, "Consolidation of Variable Interest Entities"
(FIN 46R). FIN 46R addresses consolidation by business enterprises of variable
interest entities and significantly changes the consolidation application of
consolidation policies to variable interest entities and, thus improves
comparability between enterprises engaged in similar activities when those
activities are conducted through variable interest entities. The Company does
not hold any variable interest entities.

NOTE 5 - EQUITY LINE OF CREDIT

On September 17, 2002, the Company entered into an agreement with Cornell
Capital Partners, LP (Investor), pursuant to which the Investor will purchase
the Company's Common Stock, par value $.001 per share (the "Common Stock"), for
an aggregate price of up to Seven Million Five Hundred Thousand Dollars
($7,500,000). Purchase Price" shall be set at one hundred percent (100%) of the
Market Price during the Pricing Period. Market price is defined under the
agreement as lowest closing Bid Price (as reported by Bloomberg L.P.) of the
Common Stock during the Pricing Period. The termination date of this agreement
is earliest of; (1) the Investor makes payment of Advances of $7,500,000, (2)
any stop order or suspension of the effectiveness of the Registration Statement
for an aggregate of fifty (50) Trading Days or (3) the Company shall at any time
fail materially to comply with the requirements of the agreement and such
failure is not cured within thirty (30) days after receipt of written notice
from the Investor or (4) the date occurring twenty-four (24) months after the
Effective Date. To induce the Investor to execute and deliver the Equity Line of
Credit Agreement, the Company has agreed to provide certain registration rights
under the Securities Act of 1933, as amended, and the rules and regulations
there under, or any similar successor statute (collectively, the "1933 Act"),
and applicable state securities laws.

During the Commitment Period, the Company shall not, without the prior written
consent of the Investor, issue or sell (i) any Common Stock without
consideration or for a consideration per share less than the Bid Price on the
date of issuance or (ii) issue or sell any warrant, option, right, contract,
call, or other security or instrument granting the holder thereof the right to
acquire Common Stock without consideration or for a consideration per share less
than the Bid Price on the date of issuance, provided, however, that the Investor
is given ten (10) days prior written notice and nothing in this section shall
prohibit the issuance of shares of Common Stock pursuant to existing contracts
or commitments, upon exercise of currently outstanding options or convertible
securities, or in connection with any acquisition. On the date hereof, the
Company shall obtain from each officer and director a lock-up agreement, as
defined below, in the form annexed hereto as Schedule 2.6(b) agreeing to only
sell in compliance with the volume limitation of Rule 144.

On each Advance Date the Company shall pay to the Investor, directly from the
gross proceeds held in escrow, an amount equal to four percent (4%) of the
amount of each Advance. Under the agreement, upon the execution of this
Agreement the Company was to issue to the Investor, shares of the Company's
Common Stock in an amount equal to Two Hundred Ninety Thousand Dollars
($290,000) divided by the Closing Bid Price on the Closing Date. Upon the
execution of the Agreement the Company was to issue to the Placement Agent
shares of the Company's Common Stock in an amount equal to Ten Thousand Dollars
($10,000) divided by the Closing Bid Price of the Company's Common Stock on the
date hereof. The Company has disclosed such shares totaling $300,000 in the
financial statements for the year ended September 30, 2002.

During the period ended December 31, 2003, the Company received $50,000 proceeds
from promissory notes to Cornell Capital Partners, LP, net of fee of $2,500. The
Company has settled $250,000 by issuing 6,295,947 shares of common stock during
the period ended December 31, 2003 (note 6). The notes payable outstanding at
December 31, 2003 amounted to $300,000.

NOTE 6 - COMMON STOCK

During the period ended December 31, 2003, the Company issued 2,000,004 shares
of its common stock for prepaid services amounting $137,897. The valuation of
shares was based upon market value of the shares at the time of the consummation
of the transaction. During the three month period ended December 31, 2003, the
Company amortized prepaid consulting amounting $33,897. As of December 31, 2003,

The Company issued and put 3,333,333 shares to the escrow account in pursuant to
the Equity Line of Credit during the period ended December 31, 2003 (note 5).
6,295,947 shares were issued out of the escrow account to settle the equity line
of credit, amounting $250,000. 1,383,070 shares remained in the escrow as of
December 31, 2003.

As of December 31, 2003, the Company has 7,349,204 shares of common stock to be

conditions were met. On September 30, 2003, as the conditions in the agreements
were not met, the shares awards were cancelled per the agreements between the
officers and the Company.

NOTE 7 - EARNING PER SHARE

Earnings per share for three month periods ended December 31, 2003 and 2002 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. 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 8 - RECLASSIFICATIONS

Certain prior period amounts have been reclassified to conform to the period
ended December 31, 2003 presentation.

NOTE 9 - LITIGATION, COMMITMENT & EXTRAORDINARY ITEM

LITIGATION:

The lawsuit which was 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 gain of $79,999 in the year ended September 30, 2002, for
the settlement award. The Company also recorded $17,618 as an extraordinary gain
on settlement of debts for forgiven amount of note payable as per the
settlement. In addition, all of outstanding stocks held by the defendants
totaling 7,533,701 shares were returned to the Company and cancelled by the
Company. Certain defendants appealed the settlement, but the judgment of the
court was affirmed on January 21, 2003.

      The Company's counsel was served with a motion in the Federal case by the
attorneys of Mr. Wade Cowart. The motion seeks to have the Company pay damages
of up to $100,000 in connection with a restraining order that the Federal court
previously issued against Mr. Cowart. The Company posted the potential maximum
liability of $100,000 as security bond. Mr. Cowart made motions seeking recovery
on the bond posted by the Company for the original injunction. The motion has
been briefed and is awaiting the decision of the Court.

An action filed by the Company for professional negligence, malpractice, breach
of fiduciary duty and breach of contract against Gilliam, Duncan & Harms, its
previous patent counsel was settled in June 2002. 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

                                       8

Sionix against the defendants. Harms filed a voluntary bankruptcy on December
27, 2001. Sionix filed a Complaint in the U.S. bankruptcy court, alleging claims
against Harms and disputing the dischargeability of the debts owed by Harms to
Sionix. Upon settlement agreement, the Company received $200,000 as a full and
final settlement for this Complaint. The Company has recorded this settlement
amount of $200,000 as a gain on settlement in the financial statement for the
year ended September 30, 2002. In connection with this case, the Company also
received $1,500 as a settlement for dismissal of certain parties from this
action.

The Company was the defendant in a collection action brought by a law firm that
had previously represented it, Murphey & Murphey v. Sionix Corporation. The law
firm sued the Company for the collection of $156,618 in legal fees. The Company
has filed a cross-complaint alleging, among other things, malpractice and breach
of fiduciary duty. On September 25, 2002, the Company settled the case with
payment terms of $165,000 resulting in a settlement loss of $8,382. The Company
paid $145,000 in the fiscal year 2002 and paid $20,000 in 2003.

In July 2003, an action was filed by a group of the Company shareholders located
in San Diego, alleging a variety of international and negligent acts on the part
of the Company, its officers and directors. On September 4, 2003, the Company
and its co-defendants filed demurrers and motions to strike against the
complaint. The court granted the Company and co-defendants' motions. The court
granted the shareholder group a period of forty five days to amend their
complaint and re-file same with court.

In August 2003, an action was filed in Kansas by a group of the Company
shareholders located in several states, alleging a variety of international and
negligent acts on the part of the Company, its officers and directors. Though
originally filed in the state court, the case was moved to the United States
District Court, in and for the District of Kansas. In October 2003, the Company
and its co-defendants filed a motion to dismiss the Kansas case. On October 24,
2003, the Kansas shareholder plaintiffs voluntarily dismissed their action.
Costs were assessed against the plaintiffs by the court.

DISSOLUTION OF JOINT VENTURE:

In October 2000, the Company and the Environmental Products Division of
Hoffinger Industries, Inc. ("EPD") entered into a Joint Venture Agreement to
form Sionix/EDP (the "Joint Venture"), a limited liability corporation, to
develop, market, sell and manufacture water filtration technology products. On
December 12, 2002, the joint venture was dissolved.

NOTE 10- GOING CONCERN

      The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. This basis of accounting contemplates
the recovery of the Company's assets and the satisfaction of its liabilities in
the normal course of business. Through December 31, 2003, the Company had
incurred cumulative losses of $12,822,273 including a loss of $334,793 for the
three month period ended December 31, 2003. The Company's successful transition
from a development stage company to attaining profitable operations is dependent
upon obtaining financing adequate to fulfill its research and development
activities, production of its equipment and achieving a level of revenues
adequate to support the Company's cost structure. Management's plan of
operations anticipates that the cash requirements for the next twelve months
will be met by obtaining capital contributions through the sale of common stock
and cash flow from operations. However, there is no assurance that the Company
will be able to implement its plan. In that regard, on September 17, 2002, the
Company entered into an agreement with an investor, pursuant to which the
Investor will purchase the Company's Common Stock, par value $.001 per share for
an aggregate price of up to Seven Million Five Hundred Thousand Dollars
($7,500,000) (Note 5).

NOTE 11 - SUBSEQUENT EVENT

Subsequent to the period ended December 31, 2003, the Company cancelled
7,349,204 shares issued in the prior years to officers of the Company (note 6).

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

Results of Operations (Three Months Ended December 31, 2003 Compared to Three
-----------------------------------------------------------------------------
Months Ended December 31, 2002).
--------------------------------

         General and administrative expenses in the three months ended December
31, 2003 decreased by $229,894, from $534,121 in the prior period to $304,227 in
the current period. The decrease is principally due to reduced staffing and
manufacturing expense. Research and development costs increased by $10,533,
principally due to research and development relating to expansion of the
Company's product lines. The operating loss for the quarter decreased by
$213,817, due to the decreased general and administrative expenses. Net loss
decreased by $212,908, due to the decrease in the operating loss.

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

         On December 31, 2003, the Company had cash and cash equivalents of
approximately $2,065. The principal source of liquidity has been sales of
securities. Management anticipates that additional capital will be required to
finance the Company's operations. During 2002 the Company entered into an Equity
Line of Credit Agreement with Cornell Capital, L. P. which allows the Company,
at its option, to draw funds from time to time in exchange for the issuance of
shares, up to a maximum of $7,500,000. The Company believes that available
proceeds from the Equity Line of Credit Agreement, proceeds from private
placements, and possible cash flow from the sale of products will be sufficient
to finance the Company's operations. However, the Company has no other
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 quarter.

         As of December 31, 2003, the Company had an accumulated deficit of
$12,822,273. 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.

Item 3. Controls and Procedures.

         Under the supervision and with the participation of our Chief Executive
Officer and Chief Financial Officer, we conducted an evaluation of our
disclosure controls and procedures, as such term is defined under Rule 13a-14(c)
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), within 90 days of the filing date of this report. Based on this
evaluation, our Chief Executive Officer and the Chief Financial Officer
concluded that the Company's disclosure controls and procedures are effective.
Disclosure controls and procedures are designed to ensure that information
required to be disclosed in reports under the Exchange Act are processed and
reported within the time periods specified by law. The design of any such system
of controls is based in part on assumptions about the likelihood of future
events, and there can be no assurance that any such system of controls will
succeed in all circumstances.

    Since the date of the evaluation described above, there have been no
significant changes in our internal controls or in other factors that could
significantly affect these controls.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

         On August 6, 2003 the Company was served with a complaint in an action
entitled Sullivan, et al v. Sionix Corporation, et al, filed in the Superior
Court of the State of California in Orange County (Case No. 03CC00283). The
plaintiffs, sixteen purported shareholders of the Company, seek damages and
declaratory and injunctive relief against the Company, James J. Houtz, Joan
Horowitz, Rodney Anderson and Robert McCray, directors of the Company, based on
alleged fraud and deceit, breaches of fiduciary duty and negligence. The claim
seeks general damages in the amount of at least $1 million, special damages in
the amount of at least $4,000,000, unspecified punitive damages, costs of suit,
attorneys' fees and interest. The action also seeks to enjoin the Company from
paying the legal expenses incurred by the defendant officers and directors in
the action. The plaintiffs filed a Second Amended Complaint in February of 2004.

         The Company believes the action is without merit and plans to
vigorously contest the matter.

Item 2.  Changes in Securities and Use of Proceeds

affiliates pursuant to an Equity Line of Credit agreement, for an aggregate
